Injection device
An injection device comprises a housing with a receptacle for a product, a dosing mechanism for setting a product dosage to be administered and for displaying the product dosage that has been set, and a dispensing mechanism for dispensing the product. The dosing mechanism comprises a dosing sleeve which is rotatable relative to the housing in a first direction for setting a product dosage and which is rotatable relative to the housing in a second, opposite direction for correcting or dispensing a product dosage. The dispensing mechanism comprises a piston rod, at least one sleeve, and a clutch. The device further comprises a first detector for detecting movement of the clutch relative to the dosing sleeve and/or the housing and/or the at least one sleeve and a data processing unit connected to the first detector for reading, storing, processing, transmitting, and/or displaying signals received from the first detector.
Method and monitoring device for monitoring operation of a drug delivery device
The present invention relates to a method and to a monitoring device for monitoring operation of a drug delivery device, the monitoring device comprising of at least a first and a second sensor arranged at a distance from each other with regard to a first direction and being adapted to generate a first and a second electrical signal in response to an operation of the device, a processing unit configured to determine a time delay between the first and the second electrical signals and being adapted to determine at least one state parameter of the drug delivery device on the basis of said time delay.
Point-of-Care Testing Apparatus
An apparatus for collecting, diluting and dispensing a predetermined volume of a patient fluid sample, such as blood, into the collection port of a point-of-care diagnostic test. The apparatus is constructed and arranged to collect a predefined volume of fluid sample by wicking, to mix the whole blood with a dilution reagent, and to dispense a predefined volume (within predefined tolerances) of diluted fluid sample into the collection port of the POC test kit. The apparatus has an elongate body with an internal cavity and a capillary tube in fluid connection with the internal cavity. A mixing valve separates the capillary tube and the internal cavity and selectively opens and closes the fluid connection between the capillary tube and the internal cavity. A plunger reciprocates within the valve body between a retracted limit position and a distal limit position for creating negative and positive pressure within the internal cavity.
Sensor for use with a drug delivery device
An optical decoding system including an optical sensor integral with or attachable to a housing of a drug delivery device and configured to be directed at first and second rotatable components of a dose setting and dispensing mechanism of the drug delivery device and a processor configured to: (i) cause the optical sensor to capture images of the first and second rotatable components at least at the beginning and end of a medicament dose dispensing process; (ii) determine a rotational position of both the first and second rotatable components in each of the captured images; and (iii) determine from the rotational positions of the first and second rotatable components an amount of medicament delivered by the dose setting and dispensing mechanism of the drug delivery device.
Spring arrangement and drug delivery device herewith
The present disclosure is directed to a spring arrangement for use in a drug delivery device and a drug delivery device including such a spring arrangement. The spring arrangement includes a clutch spring which is located axially interposed between a stationary housing component and an axially movable sleeve. The sleeve includes clutch features adapted to engage corresponding clutch features of a clutch element. The clutch spring biases the clutch features and the corresponding clutch features into engagement. The sleeve is coupled to a button such that upon actuation of the button the sleeve is translated against the bias of the clutch spring from a proximal position in which the sleeve is rotationally locked to the housing component into a distal position in which the sleeve is rotationally un-locked from the housing component. Upon release of the button the clutch spring translates the sleeve and the button into the proximal position.
Pen needle removal device for a drug delivery device
A removal device (121, 221) for removing and disposing of a pen needle (113, 213) connectable to a drug delivery device (111, 211) includes a body (123, 223) having a cavity (141, 241) for receiving the pen needle of the drug delivery device such that a patient end (116, 216) of a needle (115, 215) of the pen needle is covered by the body. An ejector (151, 251) is movably connected to the body (123, 223) for engaging the received pen needle (113, 213) and selectively ejecting the engaged pen needle from the body. The pen needle (113, 213) is securely retained within the removal device (121, 221) without exposing the needle (115, 215) of the pen needle until the pen needle (113, 213) can be properly disposed of, such as in a sharps container, thereby substantially preventing an accidental needle stick.
Pen-type injector
The present invention relates to injectors, such as pen-type injectors, that provide for administration of medicinal products from a multidose-cartridge and permit a user to set the delivery dose. The injector may include a housing, a piston rod adapted to operate through the housing, a dose dial sleeve located between the housing and the piston rod, and a drive sleeve located between the dose dial sleeve and the piston rod. The dose dial sleeve may have a helical thread of first lead and the drive sleeve may have a helical groove of second lead. The first lead of the helical thread and the second lead of the helical groove may be the same.
Medicament delivery device and methods for delivering drugs to infants and children
A method of delivering epinephrine includes placing a distal end surface of a medical injector into contact with a target location of a patient. The medical injector includes a housing, an energy storage member, and a medicament container containing a dose of epinephrine effective for administration to the patient experiencing anaphylaxis and having a weight of less than 15 kg. The medicament container is coupled to a needle. The medical injector is actuated such that the energy storage member produces a force to move the needle from a first needle position to a second needle position. A distal tip of the needle extends from the distal end surface by a distance of between 7 millimeters and 8 millimeters when the needle is in the second needle position. A portion of the force is exerted to expel the dose of epinephrine when the needle is in the second position.
Monitoring device
The present invention relates to a monitoring device (10) arranged to be operably connected to a medicament delivery device (12), said medicament delivery device (12) comprising a manually operated movable dose activation element (20), said monitoring device (10) comprising an electronic circuit (42), said electronic circuit (42) comprising an optical sensor (68), wherein said optical sensor (68) is positioned in relation to said dose activation element (20) so as to detect a manual operation of said dose activation element (20) from an initial position; said electronics circuit further comprising a vibration sensor (70), wherein said vibration sensor (70) is positioned in relation to said medicament delivery device so as to detect specific vibration spectra produced by the medicament delivery device when said dose activating element (20) is operated, wherein said electronic circuit (42) comprises computing elements capable of correlating the information from the optical sensor (68) with the information from the vibration sensor (70) when said dose activation element (20) is operated in order to register when a correct dose has been set.
System and method for detecting applied force during injection
A medical device (100) includes an insulin pen (102), a pen needle (104) and a force sensor (106). The device also includes a microprocessor (206) to receive a signal from the force sensor (106). Audible and/or visual indicators (218, 220) provide feedback to a user to encourage proper injection technique. The device may also include an adaptor assembly comprising a sensor housing (306) and a first sensor (304) within the sensor housing, and a transfer needle assembly (308), the transfer needle assembly providing a connection (310) for a pen needle, and providing a fluid conduit between the pen needle (312) and the insulin pen (302). A second force sensor (314) is associated with a thumb button of the insulin pen (302).
