[0055] Those skilled in the art will appreciate that elements in the Figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, dimensions may be exaggerated relative to other elements to help improve understanding of the invention and its embodiments. Furthermore, when the terms ‘first’, ‘second’, and the like are used herein, their use is intended for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. Moreover, relative terms like ‘front’, ‘back’, ‘top’ and ‘bottom’, and the like in the Description and/or in the claims are not necessarily used for describing exclusive relative position. Those skilled in the art will therefore understand that such terms may be interchangeable with other terms, and that the embodiments described herein are capable of operating in other orientations than those explicitly illustrated or otherwise described.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0056] The following description is not intended to limit the scope of the invention in any way as they are exemplary in nature, serving to describe the best mode of the invention known the inventors as of the filing date hereof. Consequently, changes may be made in the arrangement and/or function of any of the elements described in the exemplary embodiments disclosed herein without departing from the spirit and scope of the invention.
[0057] The body fluid sampling device according the invention may take on different sizes and shapes, depending on the fluid(s) and size of the sample to be collected, and on the area of the body where the sample is to be collected. The sample may be collected on the skin or on a mucosa, but the sample may have to be collected through the skin/mucosa, in such case the sampler may be equipped with a cutting blade to open the skin/mucosa and release the body fluid to be sampled. A reactant may be added by the user on the surface of the skin/mucosa to facilitate the conservation of the sample or to enable specific analyses. Optionally, the thermal inertia of the body fluid sampling device is adapted to the above parameters and to the transport constraints, so that the storage temperature of the body fluid sample is kept optimal from the user's fridge to the fridge of the analysis lab with sufficient margin. The transport of the collected sample from the user's location to the analysis lab may be done by the user himself, by postal services, or by a dedicated logistics organization using human transporters or autonomous or remotely controlled unmanned vehicles. Depending on the circumstances, the sampling device may be equipped with geo-localization and long-range communication capabilities so as to be collectable without any further action from the user after the sampling process has been executed.
[0058] The authentication of the patient and ensuring the correspondence between the authenticated user/patient and the sample, optionally with the sampling device, is optionally accomplished via differing levels of antitampering measures, as the stakes may be very high for the patient, for example, the result may determine whether the patient is placed in quarantine or released from quarantine, authorized to travel, authorized to work, it may serve as confirmation of the efficiency of a treatment, and/or the releasing of payment for a treatment, etc. Such anti-tampering measures may increase to include filming the entire body fluid sampling process from opening the box containing the sampling device to sealing the box to be mailed to the sample analysis organization, optionally encrypting, and storing the movie for later use, for example to be used as a proof in court in case of legal proceeds.

[0122] Optionally, the body fluid sampling device advantageously includes an insulating cover or sleeve adapted to slide over the sample container so as to extend the transport time possibilities. In one embodiment, the isolating cover or sleeve is manually set in place by the user via a tab actuated by the user according to written instructions provided with the device, or automatically slid in place by a second mechanism optionally triggered by thermal contraction of an element after the device has reached a sufficiently low temperature in the refrigerator.
[0123] Any embodiment of the body fluid sampling device such as those described herein is optionally equipped with a unique identification code, and may carry an electronically readable identification tag. Depending on the circumstances, the sampling device is optionally equipped with geo-localization and long-range communication capabilities so as to be collectable without any further action from the user after the sampling process has been executed.
[0124] The body fluid sampling device according the invention is made to use standard analysis tubes as well-known in the industry, so that the tubes' content can be analyzed on standard automatized analysis equipment.
[0125] The body fluid sampling device according the invention thereby provides a non-medically trained user, such as the patients themselves, with the main functionalities of:
[0126] 1. sampling a body fluid (for example blood), optionally auto-sampling (self-administered sampling);
[0127] 2. optionally dispensing one or more droplet(s) of the sampled fluid for immediate analyses: and
[0128] 3. providing a standard medical analysis tube filled with a sample of body fluid (for example blood) for analysis in a medical lab.
[0129] Referring now to
[0130] The use or operation of the device can be described as follows: [0131] 1. Typically the user holds the device between his thumb and major finger, placed on the two buttons 2, and applies his index on the safety button 1001. [0132] 2. A combination of levers, stoppers, cams, or any other mechanical elements such as well-known in the micro-mechanics art triggers the movement of the piston p1 when the buttons 1001 and 1002 are pressed by the user. At the same time, it triggers the movement of the cutting blade 1004. [0133] 3. The spring 1012 actuates the piston p1, to which the plunger-septum p2 is attached, so that the plunger impales on the needle tip ii, the tip ii piercing through the plunger, and opens the connection between the suction area 1010 and the tube chamber 1011. The cutting blade moves and cuts the skin of the patient. [0134] 4. The spring continues to pull the piston p1, so that a vacuum is created within the chamber 1011 of the medical analysis tube 1007. The patient starts bleeding, the blood is aspired through the cannula 1006 into the tube chamber 1011. The cutting blade 1004 continues its movement and retracts within the device's structure. [0135] 5. The piston p1 reaches the end of its stroke against button 1003, the suction stops, the sample is contained within the tube chamber 1011. Typically the volume of the sample is 500 μL. with one cutting blade, 1 ml with two cutting blades. [0136] 6. The user removes the device from the patient's skin, cleans the wound, applies a Band-Aid if necessary. [0137] 7. Optionally, the user uses button 1003 to expel a small part of the sample, typically 1025 μL, and uses it on an immediate test as available on the market. [0138] 8. User uses button 1003 to disconnect piston p1 from plunger-septum p2, so that plunger-septum p2 remains in the tube 1007 to keep it tightly sealed. [0139] 9. User releases the tube 1007 from the device's structure, upon removing the tube the plunger-septum p2 disengages from the cannula 1006 and closes. [0140] 10. User sends or brings the tube to a medical analyses lab to be analyzed. [0141] 11. The analysis lab analyses the blood sample and communicates the test results to the patient and/or to the relevant authorities. [0142] 12. Optionally, treatment and/or quarantine protocol is initiated to ensure that a test subject having a positive test is handled in a manner to minimize the spread of the pathogen.
[0143] In another embodiment, the body fluid sampling device according the invention may include integrated analysis functions. The sample may be collected on the skin or on a mucosa, but the sample may have to be collected through the skin/mucosa, in such case the sampler is optionally equipped with a cutting blade to open the skin/mucosa and release the body fluid to be sampled. A reactant is optionally added by the user on the surface of the skin/mucosa to facilitate the conservation of the sample or to enable specific analyses.

[0162] Referring now to
[0163] The device's structure 5000 preferably includes two or more push buttons 5200 and the mechanism 5300 is configured to ensure that only the activation of all push-buttons 5200 launches the sampling process so that the risk of inadvertent launching is minimized. The mechanism 5300 may include a combination of levers, stoppers, cams, or any other mechanical elements well known in the micro-mechanics art, or may preferably be made of flexible elements that can release the sampling just by being deformed when the user/patient presses the push-button(s) 5200. The device's structure 5000 optionally includes means to expel a small quantity of the blood from the device 4100 for quick on-site analysis. A second embodiment of the cutting blade 5450 is shown in these figures, but of course, any version could be used.
[0164] Referring now to
[0165] The suction chamber 5400 contains 1 or more cutting blade(s) 5450 of a second embodiment, in principle 1 for up to 500 μl, and 2 if 1 ml need be collected, as required depending on the sample size to be collected. For the reader's information, the duration of blood flow is about 30′ for 500 μl for one incision, and so about the same time for 1 ml using two incisions. The cutting blade 5450 has an elastic or spring portion 5458 which has been loaded at the assembly of the device 4100, and is held under tension by a mechanical finger 5350. The mechanical finger 5350 is linked to the mechanism 5300 so that the mechanism 5300 can release the cutting blade 5450 when actuated. The cutting blade is positioned so as to lacerate the user/patient's skin through the passage 5150 when released. The suction chamber is closed by an air-tight membrane 5420 made of an air-tight material that can be lacerated by the cutting blade 5450 while at the same time cutting the user/patient's skin without tearing. Optionally, the suction chamber 5400 contains an air-tight elastic lining 5410 which allows the mechanism 5300 to actuate the mechanical finger 5350 in an air-tight manner, and optionally includes means to expel a small quantity of blood for quick on-site analyses. Appropriate materials for the membrane 5420 and the optional elastic lining 5410 are well-known in the art and may include silicone, rubber, and other elastomers and/or plastics in one or more layers. The suction chamber 5400 is made so as to minimize its volume, so that the majority of the collected blood doesn't remain in the suction chamber 5400 and can be fed into the vacuum tube, and a minimal part of the vacuum provided by the tube is used to establish vacuum in the suction chamber 5400. The channel 7000 connecting the suction chamber 5400 to the inside 6100 of the tube holder 6000 may be a needle 7200 with the suction end 7100 of the needle connected to the suction chamber 5400 and the dispensing end 7300 of the needle adapted to enter the vacuum tube and bring the collected blood into the tube. Typically, the needle 7200 may be made of stainless steel, but other materials available nowadays in the industry such as other metals, composites and/or plastics may be used.

[0182] In another embodiment, the device 4100 may be remotely triggered via a smartphone, optionally, following a face recognition or recognition of a QR code visible on the device. Given the device is glued on the arm, the patient has a hand free to control such remote triggering.
[0183] In still another embodiment, the capillary blood sampling system according the invention includes a patient biometric based authentication system, a device authentication system and a disposable capillary blood sampling device providing a non-medically trained user with the ability to (a) sample a capillary blood, optionally auto-sampling; (b) optionally, using one or more droplet(s) of the sampled capillary blood, to immediately analyze blood; and (c) to provide a standard medical analysis tube filled with a sample of capillary blood for analysis in a point of care or in a medical lab, the device including an interface for a vacuum tube, the vacuum tube providing suction necessary to fill the vacuum tube with the blood.

[0205] As a result, the adhesive integrated dressing 3174 is adapted to ensure the attachment of the blood sampling device 3100 to the patient's skin, the air-tightness between the patient's skin and the blood sampling device 3100 during the sampling process, and the dressing of the wound after the sampling process.
[0206] In another embodiment, the vaccine and/or drug injecting device according the invention provides a non-medically trained user with the ability to (a) inject vaccines and/or drugs, optionally auto-injecting; (b) a data processing and validating system which is configured to receive data related to the vaccine and/or drug entered by the user/patient through the app, or by the HMO who received it previously (whereby the entry of the data may be performed e.g. manually or by scanning a QR-code); and (c) a system configured for sending to and, optionally, receiving from a network (such as the Internet) data.
[0207] Self-administration may be accomplished with the help of devices such as those described in PCT/US2012/048044, PCT/IB2018/000559; PCT/IB2013/000659; and PCT/IB2020/055874, the contents of which is incorporated herein by reference thereto and relied upon.
[0208] As emphasized earlier, the present invention provides means for the injection and administration of vaccines and/or drug by a non-medically trained user, the means being implemented in a vaccine and/or drug injection device. The vaccine and/or drug injection device of the invention may use one or more needle(s) as means to inject the vaccine and/or drug into the user/patient's body. For the purpose of the present disclosure, the functioning of the vaccine and/or drug injection device of the invention is described as if containing one needle, but it must be understood that the injecting device of the invention may contain more than one needles in order to increase the amount of vaccine and/or drug injected and/or to decrease the injection time. The vaccine and/or drug injecting device according the invention provides a non-medically trained user with the ability to (a) inject vaccines and/or drugs, optionally self-injecting; (b) a data processing and validating system which is configured to receive data related to the vaccine and/or drug entered by the user/patient through the app, or by the HMO who received it previously (whereat the entry of the data may be performed e.g. manually or by scanning a QR-code); and (c) a system configured for sending to and, optionally, receiving from a network (such as the Internet) data.
[0209] The device according to the present invention allows authentication for vaccines and/or drug administration. Therefore, the device according to the present invention comprises means to allow the verification of one or more of the following items:
[0210] 1. The data of the physician or healthcare responsible (MED) for the vaccines/drug administration and his/her (MED) specific approval for the use of the vaccines and/or drug administration to the user/patient. The device according to the present invention is adapted to receive data related to the vaccine and/or drug entered by the user/patient through the app, or by the HMO who received it previously (whereby the entry of the data may be performed e.g. manually or by scanning a QR-code).
[0211] 2. The temperature of the vaccines and/or drug administration from shipment to injection (if required). The device according to the present invention is adapted to handle information from a temperature tracer or reagent paper (typically placed in a shipment box during shipment), optionally GPS tracer (also typically placed in a shipment box during shipment). Optionally, the tracers can be returned to the vaccine and/or drug producer. Related to the device, a timer must be switched on in the app when the user/patient takes the device out of its thermal protection. Warnings have to be given by the system (app and/or device) to the user/patient related with this event.
[0212] 3. Patient safety in case of patient reaction a) immediately at the time of injection (e.g. fainting); and b) after the vaccine (e.g. 15 minutes after the injection). For the aforementioned situation a), the device according to the present invention is adapted to receive from the user/patient an input (e.g. by pushing a physical button or a button in the app), so as to validate that the injection has been given. If there is no validation after a certain time after the patient has initiated the injection, an alarm is triggered to alert the MED, and, optionally, trigger an emergency procedure. For the aforementioned situation b), the system of the present invention is configured to allow the user/patient to confirm (e.g. by pushing a physical button or a button in the app) to the MED that he or she is not in need of emergency aid.
[0213] The main features of a vaccine and/or drug injecting device of the above embodiment of the invention are that the body of the injecting device contains a mechanism that actuates the needle of the invention when the user/patient depresses the “inject” button. Such mechanism is well known in the micromechanics arts, and can contain levers, clips, springs, flexible elements, sliders, gears, cams, etc.
[0214] The injection device can be any suitable injection device such as those depicted in US patent applications Nos. 63/114,162, 62/864,572, 62/511,361, Ser. Nos. 15/524,748, 31/040,459, 14/235,107, and 16/930,383, the content of which is incorporated by reference and relied upon as critical disclosure in the present application.
[0215] Capillary blood sampling devices for non-medically trained users of the current art usually create the wound in the patient's skin by perforation with one or more needles, or even without perforation, which only allows for the collection of relatively small volumes of fluid, typically less than 150 μl in 5-10 minutes.
[0216] In another embodiment, the present invention provides means for the capillary blood sampling device 10, 1100, 2010, 2210, 3100, 4100 to make a significantly larger cut than what is usually known in existing capillary blood sampling devices, so that a significantly larger amount of blood, typically more than 500 μl, preferably 1 ml can be collected over a reasonable period of time, typically less than 15 minutes, preferably less than 10 minutes. The capillary blood sampling device of the invention uses one or more cutting blade(s) 1004 (e.g., but not limited to cutting blades 302, 5450, 5456, 3260, 3360, 3460), instead of one or more needle(s), so that the user/patient's skin is lacerated instead of punctured. For the purpose of the present disclosure, the functioning of the sampling device of the invention is described assuming it contains one cutting blade, but it must be understood that the sampling device of the invention may contain more than one cutting blade in order to increase the amount of blood collected and/or to decrease the blood collection time. Moreover, the current invention provides cutting solutions that favor a quick healing of the wound after the blood sampling is complete. The purpose of the invention is therefore to create a wound in the user/patient's skin that has an optimal depth for cutting as many capillaries as possible, while avoiding unnecessary wound width and length so that the natural healing of the wound can happen as fast as possible after the blood collection. The ideal cutting depth may vary as function of the patient's age, gender, ethnical group and/or health condition, as a result several adapted versions of sampling devices may be provided. Typically ideal cutting depth is between 1 mm and 2 mm.

[0219] Typically, the natural release trajectory 3250 of the cutting blade 3260 is substantially circular, elliptical or spiral. As a result, the laceration in the patient's skin 3290 is substantially circular and with a relatively large radius, and the wound length 3296 is relatively long for a small portion at the desired depth 3292. When elements of the device's structure 3242, 3244, 3246 interact with the finger 3270 of the cutting blade 3260, the resulting trajectory 3240 of the cutting blade 3260 is modified so that the resulting laceration of the patient's skin 3290 has a steeper dive and retraction path, resulting in a shorter wound length 3294 for a longer proportion of the wound at the desired depth 3292. The modified trajectory 3240 allows for a larger volume of capillary blood to be collected, for a globally smaller wound, favoring a quicker healing of the wound after the blood collection.

[0223] Typically the natural release trajectory 3350 of the cutting blade 3360 is substantially circular or spiral. As a result, the laceration in the patient's skin is substantially circular and with a relatively large radius, and the wound length is relatively long for a relatively small portion at the desired depth. When an element of the device's structure 3342 interacts with the finger 3370, the resulting trajectory 3340 of the cutting blade 3360 can be modified so that the resulting laceration of the patient's skin has a steeper dive and retraction path, resulting in a shorter wound length, and a longer proportion of the wound at the desired depth. The modified trajectory 3340 allows for a larger amount of blood volume to be collected, for a generally smaller wound, favoring a quicker healing of the wound after the blood collection. As an example, the element of the device's structure 3342 is made to shrink locally the radius 3352 of the natural release trajectory 3350 by an offset 3341 on a part of the release trajectory 3340. In addition, the element of the device's structure 3342 can be made with a more complex shape so as to provide a more elaborated modified trajectory 3340.

[0228] In another embodiment, the invention provides for verification of self-administered medical processes. An objective of this embodiment is to make sure the user/patient is identified: [0229] For blood sampling: to make sure the blood in the sampling tube(s) is the blood of this patient [0230] For injection: to make sure the injection is made in this patient. [0231] What may be at stake here is: [0232] For blood sampling [0233] Reliable blood sampling; [0234] Authorization to work, to travel, to be in contact with family in times of epidemics; [0235] Authorization to use a certain treatment; [0236] Automatized detection of epidemics by large-scale sampling programs; [0237] Verification of the efficiency of a given treatment (payment subject to treatment success);
[0238] For Injections: authorization to work, to travel, to be in contact with family after a vaccine/treatment has been taken may be at stake. In addition, keeping personal immunization record up to date and automatized monitoring of large-scale vaccination programs is at stake. Still further, payment of a treatment may be at stake, contingent on vaccination and only if fully administered. Therefore, making a secure patient & process verification is crucial.
[0239] In another aspect, verification of self-administered medical processes is important. For example, use of a smartphone application may be made in order to make a video (or a time-lapse) where the patient's face as well as the process itself are visible in the video all along the process duration. A comparison of the patient's ID with the patient's face may be made. The patient's face recognition and whole process may be observed. The system could be configured to launch the process only when all ID's are confirmed. Automatized handling of the logistics (sampling tube collection & transport, treatment re-supply, etc.) may be implemented. In the case that the smartphone app is configured to analyze the video in real-time, step-by-step instructions may be provided to the patient in real-time, while the process is being executed. Other features could be included such as automated monitoring of process performance. Despite the potential, there will always be challenges to deal with, particularly in degraded conditions, when dealing with insufficient network coverage at the moment of running the process. Optionally, temporary network coverage may be provided via drones/balloons for the duration of the treatment campaign. It would be best however, if the App is able to run independently of network coverage. Saving all data on the smartphone and making verifications at a later stage may also be desirable. Respecting private data regulations is an issue of course. The App may be configured to run a first analysis and then an encryption routine to make private data unreadable, with full video optionally saved for later use in case of need (e.g. formal proof in a court).
[0240] Main components of the system include a smartphone or laptop/computer or similar and camera (may be included in the smartphone/laptop/computer), the application to be run by the smartphone or laptop/computer; the device for running the injection/sampling process, which may be re-usable. In addition, the treatment to be injected/one or more empty tubes/vials to contain the collected blood sample(s) (may be under vacuum).
[0241] As for some key features of the system of the invention, the app must be able to read treatment container/sampling tube's unique ID using for example a standard bar-code/QR-code. The App must be able to identify key process steps. The device may need to include automatized wireless signal emission (information: ID/process started/process ongoing/process finished/error). Such signal may be visible (e.g. blinking/colored LEDs) for easy interpretation in the video. The device of the invention may optionally include visible features/landmarks for easier orientation verification in the video. The App should be able to launch the treatment process. The device is optionally equipped with remote triggering feature and advantageously includes a unique ID.
[0242] Referring now to
[0243] The invention may have other uses. For example, it may be applied to another medical treatment other than an injection (the device may be a pills distributor). It may be applied to filling a voting form at home, signing documents, proving one's ID during a teleconference, or taking a remote exam.
