Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a urine test strip paper separating device. Background Art

[0002] With the development of modern medical testing technology, urine testing has become one of the routine testing items in clinical medicine. In the process of urine testing, test strips are indispensable consumables. The test strips need to be inserted into the urine analyzer to realize urine testing. In order to improve its efficiency and accuracy, test strip sorting devices are often used to send them out.

[0003] Most of the existing test strip sorting devices are of the drum type and the flat plug-in plate type. Both the drum type test strip sorting device and the flat plug-in plate type test strip sorting device must adjust the gap between the hopper and the moving part so that the gap can just allow one test strip to pass through in order to achieve paper separation. When the gap is greater than the thickness of a test strip, there is a high probability that two test strips will be separated at the same time, causing the device to be unusable. The test strips used are of different thicknesses, and the gap between the hopper and the moving part remains unchanged after adjustment. When encountering thinner test strips, it is very likely that two test strips will be separated at the same time. When encountering thicker test strips, the moving part will get stuck and cause a malfunction. Summary of the invention

[0026] The driving mechanism includes a first motor 5 and a connecting rod 1 6 and a connecting rod 2 7 which are hinged at one end. The first motor 5 is installed on the support seat 2 on the left side of the base 1 through a fixing frame. The end of the connecting rod 1 6 away from the connecting rod 2 7 is hinged to the output shaft of the first motor 5, and the end of the connecting rod 2 7 away from the connecting rod 1 6 is hinged to the bottom end of the inclined plate 3.

[0027] A connecting piece 8 is fixed to the central axis of the bottom end of the inclined plate 3 away from the hopper, and the connecting piece 8 is hinged to the end of the connecting rod 2 7 away from the connecting rod 1 6.

[0028] The hopper includes a symmetrically arranged first hopper wall 9, and the two first hopper walls 9 are respectively installed and fixed on the support seat 2 on the corresponding side through a connecting block 10. The side of the connecting block 10 is L-shaped, which is convenient for tightening the first hopper wall 9 close to the support seat 2 and the top of the support seat 2 through bolts. The first hopper wall 9 is installed on the support seat 2 on the corresponding side through the connecting block 10. There is a certain gap between the first hopper wall 9 and the support seat 2, which is convenient for the slider 19 to move along the slide groove 18, so that the slider 19 and the first hopper wall 9 do not conflict with each other. The first hopper wall 9 is arranged in a right-angled triangle, and the hypotenuse of the first hopper wall 9 is arranged in affixed with the inclined plate 3 to prevent the reagent strip from falling from the gap. One right-angled side of the first hopper wall 9 is parallel to the top of the support seat 2, and the other right-angled side is parallel to the front of the support seat 2. A second hopper wall 11 is arranged between the other right-angled sides of the two first hopper walls 9, and the bottom end of the second hopper wall 11 is fixed with a The third hopper wall 12, the bottom end of the third hopper wall 12 abuts against the inclined plate 3, the angle between the inclined plate 3 and the third hopper wall 12 is about 95-110 degrees, which can make the reagent strip in the hopper fall without hindrance, the symmetrical surface of the first hopper wall 9 is provided with a mounting groove, the mounting groove is provided with a fourth hopper wall 13, the bottom end of the fourth hopper wall 13 is fixed with a stopper 14 arranged toward the third hopper wall 12, the stopper 14 is arranged parallel to the inclined plate 3, and the stopper 14 is in the shape of a triangular pyramid The gap between the stopper 14 and the inclined plate 3 is larger than the thickness of one test strip and smaller than the thickness of two test strips. When the test strips are moved upward along the inclined plate 3 (except for the test strips contained in the test strip slot 4), part of them are blocked by the stopper 14 and slide back into the hopper. Part of the test strips not blocked by the stopper 14 fall back into the hopper due to gravity. The last part of the test strips are swept back into the hopper by the sweeping wheel 21 (brush), thereby realizing the function of separating a single test strip.

[0029] The third hopper wall 12 is provided with a plurality of prisms 15 for mounting test strips at equal intervals. The test strips are in conflict with the prisms 15 and are not in direct contact with the third hopper wall 12, which can effectively prevent the test strips from adhering to the third hopper wall 12 and causing the test strips to block the hopper, and has a certain protective effect on the test strips. The bottom end of the third hopper wall 12 is evenly provided with a plurality of limit blocks 16 extending downward and parallel to the prisms 12, and a first through groove 17 is provided on the inclined plate 3 corresponding to the limit blocks 16. The combination of the limit blocks 16 and the first through groove 17 can effectively prevent the test strips from falling along the lower end of the inclined plate 3.

[0030] A slide groove 18 is provided on one side of the hypotenuse of the first hopper wall 9 close to the support seat 2, and sliders 19 matching the slide groove 18 are provided in the middle of the left and right ends of the inclined plate 3. The inclined plate 3 is slidably set at the discharge port through the connection between the sliders 19 and the slide groove 18. The first hopper wall 9 is hinged at the rear end of the fourth hopper wall 13 with two auxiliary wheels, and the two auxiliary wheels are used to assist the inclined plate 3 to slide along the discharge port.

[0031] A rotating rod 20 is rotatably mounted on one end of the inclined plate 3 between the top ends of the two first hopper walls 9, and a plurality of sweeping wheels 21 are evenly distributed on the rotating rod 20. The sweeping wheel 21 is a brush, and a fixed shaft is arranged between the brush and the fourth hopper wall 13. Both ends of the fixed shaft are respectively inserted into the first hopper wall 9 on the corresponding side. The fixed shaft is used to clean dust or other things on the brush. The brush can brush off excess test strips and clean dust and impurities. One end of the rotating rod 20 passes through the first hopper wall 9 on the corresponding side and is provided with a driven wheel 22 through a coupling. The bottom end of the coupling is fixed to the support seat 2 on the corresponding side. The driven wheel 22 is connected to a second motor 23 through a belt, and the second motor 23 is installed on the support seat 2 below the coupling.

[0032] A transfer mechanism for taking out the test strips in the test strip slots 4 is provided at one end of the two support seats 2 away from the hopper.

[0033] The transport mechanism includes a rotating shaft 24 disposed above the support seat 2, both ends of the rotating shaft 24 are connected to the top of the support seat 2 through a connecting rod 25, at least one strip-taking hook 26 is evenly distributed on the rotating shaft 24, one end of the rotating shaft 24 passes through the connecting rod 25 on the corresponding side and is provided with a third motor 27, the third motor 27 is installed on the support seat 2 on the corresponding side through a motor seat, the upper part of the inclined plate 3 passes between the support seat 2 and the rotating shaft 24, and the inclined plate 3 is provided with a second through slot 28 corresponding to the strip-taking hook 26. The strip-taking hook 26 takes out the test strip from the test strip slot 4 and is taken away by an external pushing mechanism or other device.

[0034] The support seat 2 is arranged in a 7 shape, the hopper is arranged between the outer corners of the two support seats 2, the second motor 23 is located at the inner corners of the two support seats 2, the bottom ends of the two support seats 2 (i.e., one end of the 7-shaped support seat 2) are fixedly installed with the base 1, and a transfer mechanism is installed above the other ends of the two support seats 2 and the other end of the 7-shaped support seat 2.

[0035] The working principle of the present invention is as follows: the test strips are stored in the hopper, the first motor 5 drives the rotating rod 1 6 to rotate around the first motor 5 and drives the rotating rod 2 7 to move around the connecting member 8 in a fan shape, and finally drives the connecting member 8 to drive the inclined plate 3 to move up and down along the inclined mouth. When the inclined plate 3 moves down to the discharge port of the hopper, the test strips fall into the test strip slot 4, and the first motor 5 drives the inclined plate 3 to move up along the discharge port. Since the inclined plate 3 is inclined at an inclined angle to form a slope, during the upward movement of the inclined plate 3, except for the test strips in the test strip slot 4, most of the remaining test strips will slide down along the inclined plate 3 (part of which is blocked by the block on the fourth hopper wall 13). 14 is blocked, and a part of it slides back into the hopper due to its own weight), and returns to the hopper. When the test strips follow the inclined plate 3 to move up, that is, a few test strips are sucked up by the inclined plate 3, the brush will brush off the excess test strips during the self-rotation (driven by the rotating rod 20 to rotate) and re-enter the hopper to ensure that only one test strip is separated. The inclined plate 3 separates the test strips one by one in the reciprocating motion, and the brush can clean the dust and impurities on the inclined plate 3 and in the test strip slot 4 during the self-rotation process to ensure the long-term normal operation of the equipment.
