DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0115] The foregoing embodiments discloses as an example system, means and methods are provided for collecting, sampling and testing stool samples, all pertains to both mechanical and electrical, manual, semi-automatic, automatic means and methods for automatic sampling and homogenization or extraction of the stool samples, enabling their usability in various diagnosis and detection applications.

[0116] A toilet is a fixture used primarily for the disposal of human urine and feces (stool). In one embodiment of the invention, the term toilet refers in a non-limiting manner to the commercially available western vortex-flushing toilet bowl, which creates a self-cleansing effect. The term toilet seat refers in a non-limiting manner to a hinged unit consisting of seat, and usually a lid, which is bolted onto a toilet bowl for a flush toilet. A toilet seat may consist of the seat itself, which may be contoured for the user to sit on, and the lid, which covers the toilet when it is not in usethe lid may be absent in some cases, particularly public restrooms.

[0117] A detector for analyzing stool specimen, according to the present invention, refers to any means for stool test involves (e.g., biological-, microbial- or chemical-) analysis of fecal matter to diagnose the presence or absence of a medical condition, more specifically, yet in a non-limiting manner, stool test as referred hereinafter, includes biomarkers, microbial marker, chemical markers in general. More specifically, and in a way of example, stool test includes fecal occult blood test, the fecal occult blood test is commonly used to diagnose many conditions that cause bleeding in the gastrointestinal system including colorectal cancer or stomach cancer. Stool tests also include microbiology tests, namely parasitic diseases such as ascariasis, hookworm, strongyloidiasis and whipworm can be diagnosed by examining stools under a microscope for the presence of worm larvae or eggs. Some bacterial diseases can be detected with a stool culture. Toxins from bacteria such as Clostridium difficile (C. diff) can also be identified. Viruses such as rotavirus can also be found in stools. Stool tests further include chemical tests, namely a fecal pH test may be used to determine lactose intolerance or the presence of an infection. Steatorrhea can be diagnosed using a fecal fat test that checks for the malabsorption of fat. Stool tests further include fecal immunochemical test (FIT) and stool DNA test (sDNA), e.g., the PreGen-Plus test, stool guaiac test for fecal occult blood (gFOBT), fecal porphyrin quantification: e.g., HemoQuant. Hence for example, fecal occult blood (FOB) refers to blood in the feces that is not visibly apparent (unlike other types of blood in stool such as melena or hematochezia). A fecal occult blood test (FOBT) checks for hidden (occult) blood in the stool (feces). Similarly, tests may look for globin, DNA, or other blood factors including transferrin, while conventional stool guaiac tests look for heme.

[0118] It is an essence of the present invention to provide means and methods for easy and hygienic collection of stool, provided in a retraction/spring-like mechanism which is designed to collect a stool sample and transfer a specimen of it into an extraction-homogenization buffer, with minimal handling and minimal manual operation. The retraction/spring-like mechanism may be provided in some embodiments with a stool collector for directly eliminating stool upon it, and it may also be provided in some embodiments with a built-in detection unit. Thus, in various embodiments, the present invention provides an easily operable and elegant solution for diagnosing stool, by providing a system which enables the steps of the entire diagnostic processfrom collecting the stool, through homogenizing it with a buffer and on to the detection processing, without having to manually perform any step.

[0119] Reference is now made to FIG. 1 schematically presenting a perspective three-dimensional view of a first embodiment of the present invention, providing retractable swab 3, along with retraction/spring-like mechanism 10 provided in housing 11. The retractable swab 3 is configured to have a proximal end connected to retraction/spring-like mechanism 10, found within housing 11, and a distal end which is switchable between two configurations: an extended configuration, having the distal end located outside of housing 11, and a retracted configuration, having the distal end located inside housing 11. In the embodiment shown in FIG. 1, housing 11 is characterized by a round bottle-like shape, having top cover 8 and bottom sealing cover 13. In some embodiments, interconnected to housing 11 is swab-conducting tube 5, which is a tube-like member directing to an aperture in housing 11, and facilitating the transfer of retractable swab 3 from an extended configuration to a retracted configuration and vice versa. Retractable swab 3 may also be provided with cap 4, for sealing and closing the aperture in housing 11, or the aperture in swab-conducting tube 5.

[0120] In its extended configuration, retractable swab 3 is designed to be in contact with a stool specimen, and configured to retain at least a portion of the stool on its surface area. In its retracted configuration, retractable swab 3 is designed to be incorporated into housing 11, and specifically to be in contact with homogenization chamber 22, which preferably comprises a homogenizing buffer. The buffer may be provided in some embodiments in a sack-like compartment inside chamber 22. The switch between the extended configuration and the retracted configuration is performed by operating operation button 7, which may be in a non-limiting manner a pin, a safety catch, clasp, knob, clamp, snap, latch, or a bolt and thus may be operated by pressing, pushing, pulling, twisting, sliding and any combination thereof.

[0121] It is in accordance with an embodiment of the present invention, wherein the apparatus is configured to provide homogenized stool to an external diagnostic unit. A non-limiting example would be a dripping mechanism which would enable dripping the homogenized stool directly onto a strip provided externally to the apparatus.

The swab dimensions are configured to provide the analysis volume a specific, predefined and constant (meter-dose) stool analysis volume. Stool resecting lips 210 can be used. The swab retracting mechanism 139 can be in connection with a plurality of swiveling, actuating or rotating wings which homogenize the stool-in-buffer solution so a homogeneous solution or suspension is provided. The device may also contain an analysis window 250 or any display for showing in a direct or indirect (e.g., wireless) manner.

Step III (FIG. 22c) depicts indicating analysis result(s) on one or more windows 250 showing, qualitatively or quantitatively, presence or one or more predefined suspected pathologies. In a manner of example, faecal calprotectin analysis is set for upper limit of 112 g/g of faece; positive (green, upper window 201) indicates patient has lower calprotectin than set limit. Hence, patient apperantly has no IBD-related indication. The lactoferrin concentration (microgrammes/gram faecal weight) is 01.4 for IBS patients, 6.642 for UC patients, 412.7 for CD patients and 0.52 for healthy controls (medianinterquartile range), see http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2036.2010.04306.x/abstract, currently available link which is incorporated herein as a reference. Hence, simultaneously and concurrently to said calprotectin analysis, lactoferrin is analyzed in an analysis set at upper limit of 20 g/g showing the patient has an idiopathic non-IBD infection. Thus, overall checkup of an IBD-patient shows he/she currently suffers from a GI infection which seemingly not related with his/her IBD illness.

Example 1

[0196] One embodiment of the aforesaid retractable stool's specimen swab is hereby presented as a non limiting example. This stool sample collecting and diagnosing device and kit thereof is characterized by a first (e.g., multiuse-) module comprising a motor actuating a rotatable axle; and a second (e.g., disposable-) module comprising: a rotatable shaft reversibly connectable with the axle, the shaft is further connected to and wounded by an elongated cord's proximal portion, the cord's distal portion comprises means for retaining stool material when introduced in or at the surface of stool to be sampled; a pierceable chamber with predefined volume of stool-sample homogenizing fluid; a stool-sampling cabinet of a predefined volume throughout which the cord is crossing from the shaft via at least one stool resecting lip and from an aperture of the cabinet cork outwardly, the cabinet configured to accommodate a meter dosed stool sample; and a diagnosing strip to which a predefined small volume of stool sample is introduced after being wet by the homogenizing fluid.

[0197] It is another object to of the present invention to provide a method of stool sample collecting and diagnosing by means of a device as defined above and below.

[0198] Reference is now made to both FIG. 23 & FIG. 29a&b, which schematically illustrate a side view of a stool sampler according to an embodiment of the present invention. This stool sampler, interchangeably further termed hereinafter as device, sampler, kit, comprises as a kit two modules: a first module, provided hereinafter in a non-limiting manner as a multiuse module, A comprising inter alia a motor; and second module, provided hereinafter in a non-limiting manner as a disposable, changeable or replicable module, B, reversibly interconnectable to said first (e.g., multiuse-) module, A and comprises the collecting and diagnosing systems.

[0199] Let's begin the description with the description of one embodiment of the disposable module, B. An elongated stool sampling cord (301), having a main longitudinal axis, the cord comprises a stool retaining structure and surface at its distal portion, and a proximal tip configured to anchor a rotatable shaft (305) thus reciprocally and reversibly be wounded along shaft (305), thereby elongating or shortening cord's length along its main axis to a required measure.

[0200] In this embodiment, the cord snugly pierces an aperture (302a) in a cork or stopper (2b) plugged over both (i) an inner meter-dozed stool sample collecting cabinet (303a) and (ii) a tube-like container (304) provided in a concentered manner outwardly said cabinet (303a). Stool sample collecting cabinet (303a) is having at least one stool resecting lip, here, e.g., a syncline of concaved rubbed lips (303b), wherein container (304) is configured to retain a predefined measure of a fluid for homogenizing said meter-dosed stool-sample.

[0201] As defined above, rotatable shaft (305) is in connection (e.g., coupled directly or provided via a gear mechanism) with an axle of electric motor (308) that spins the interconnected cord clockwise, counter-clockwise or both, in one speed (single RPM) or in a range of RPMs. It is in the scope of the invention when the motor is selected from various types possible, e.g., electric motors, mechanical motors, spring loaded mechanical motors, automatic motors, semiautomatic or manually activated motors etc. By aforesaid shaft's rotation, the cord initially elongates to a desired length so the cord can be conveniently inserted to or adjacent to a stool to be sampled, e.g., stools in a remote toilet bowl. After cord's distal portion is contacted with said stool, shaft's rotation shortens the cord, and by its way backwardly, stool enters cabinet (303a) via cork's piercing aperture (302a), whist stool accommodates within stool cabinet (303a) and not leaving the cabinet due to the effective resection action and the wiping of the cord by resecting lips (303b). Hence, backward rotation of the shaft provided a meter-dosed stool sample within the sampling cabinet. Upon subsequent piercing of both cabinet (303a) and fluid container (304), fluid is effectively wetting the stool thus extracting the markers to be analyzed and provide the suspension to appropriate rheological properties allowing the sample to flow and be diagnosed on a diagnosing strip. Then, rapid rotation of the shaft spins cord's abutment, the effective stiffing homogenizing the wetted stool suspension, allowing predefined one or more soluble markers to wet one or more diagnosing strips, and thus quantitatively, semi-quantitatively or qualitatively real-time indicating the condition of a patient.

[0202] Reference is now made to both FIGS. 24-27 which schematically illustrate views of disposable module B of a stool sampler according to the above defined embodiment. FIG. 24 schematically shows one diagnostic strip (314), having, according to one embodiment of the technology red (314a) or green (314b) indications for under a critical measure or significant over critical measure of a marker of a medical condition, respectively; or according to yet another embodiment of the technology, indication of a first marker of a first condition (marking strip of window 314a) and/or second marker of a second condition (marking strip of window 314b) etc.

[0203] Hence for example, 60 g/g faecal calprotectin can be provided as a critical measure for IBD condition, See Smith, Lyn A., and Daniel R. Gaya. Utility of faecal calprotectin analysis in adult inflammatory bowel disease. World J Gastroenterol 18.46 (2012): 6782-678 which is incorporated herein with its citations as a reference. Much similarly, critical measures are indicative for fecal occluded blood tests, see Beg, M., et al. Occult gastro-intestinal bleeding: detection, interpretation, and evaluation. JIACM 3.2 (2002): 153-158; lactoferrin, see Vaishnavi, Chetana, Deepak K. Bhasin, and Kartar Singh. Fecal lactoferrin assay as a cost-effective tool for intestinal inflammation. The American journal of gastroenterology 95.10 (2000): 3002; those two and citations thereof are incorporated herein as references.

[0204] Reference is still made to FIG. 24 schematically illustrating a front view wherein diagnosing button (315) comprising a piercing member, e.g., a pushable drawing pin-like member, having a movable, pushable, rotatable or otherwise actuatable head and a nail interconnected with said head and substantially perpendicular to head's plane. When actuated, the nail pierces a separating wall, membrane or the like. The nail shank has at least one crossing aperture, configured to be expose, thus being open, when actuated and piercing said wall or membrane; thus providing a capillary-size open aperture for flowing of homogenized stool fluid from the inner volume of the disposable module to the lower portion of diagnostic strip 314. It is acknowledged that thin-layer chromatography (TLC), filter paper strips and other diagnostic members are utilizable here, see Sherwal, B. L., and Subhash Dadeya. Filter paper strip kit: a cost-effective transport media. Tropical doctor 35.2 (2005) and references thereof incorporated herein as a reference.

[0205] Reference is now made to FIG. 25, schematically illustrating a perspective view of the disposable module B. Cord (301) is freely yet sealingly reciprocated linearly along cord's main axis, via cork's aperture. The cork (302) is a stopper provided as a top wall of container 4. Rotatable shaft 5 has a main longitudinal axis; one side along said axis is provided within the disposable module where is connected to the proximal end of the cord. Its opposite end (6), located outside disposable module B, is a push-in fitting or push-in connector, configured for fast, reversible and easy connection of the disposable module B, via shaft's push-in connector with the multiuse module A, via motor's axle or gear thereof.

[0206] Now for the description with the multiuse module, A. Reference is now made to FIGS. 23, 26, 28 29a & 29b. Multiuse module A comprises, inter alia, at least one motor (308), e.g., electrical motor, and power source, e.g., one or more 1.5V batteries (309), a processor (306) is connected to the motor. On/Off switch (312) is connected to the same. In one example, the motor, batteries and processor are hermetically enveloped by O-ring (311) containing lid (313) of the water-proof housing (307).

[0207] According to one embodiments of the invention, multiuse module A further comprises image acquiring means, such as color CCD, or data acquiring sensors, and a processor and communicator configured to acquire the diagnostic results and real-time transmit it to a remote location, to a remote smartphone e.g., via Wi-Fi of Bluetooth communication protocols.
