Description

Technical Field

[0001] The utility model relates to the technical field of urine testing equipment, in particular to a device for testing urine of a patient. Background Art

[0002] Traditionally, before placing the patient's urine into the testing equipment for examination, a reagent strip needs to be immersed in the urine sample so that the urine sample reacts with the reagent and produces a color change. The reagent strip adsorbed with urine is then placed in the colorimetric slot of the urine analyzer for testing. The urine testing equipment automatically calculates the corresponding results of various components by comparing the color in the reagent strip and the reflectivity of the urine with the standard curve.

[0003] The patent document with application number 202321733901.2 discloses a urine inspection device, including a box body and a controller arranged on the side wall of the box body, a detection cup and a recovery trough are installed on the lower wall of the box body, an electric slide rail is fixedly provided on the upper wall of the inner wall of the box body, an electric telescopic rod is connected to the electric slide rail, the lower end of the electric telescopic rod is connected to a mounting frame, a detector and a stirring blade are respectively provided on the lower wall of the mounting frame, a motor is correspondingly provided on the upper wall of the mounting frame, and the stirring blade and the motor are connected to each other; the mounting frame and the stirring blade are connected to each other by a clamping fixing component.

[0004] However, in actual operation, due to various factors (such as the viscosity of urine, the material of the reagent strip and improper operation, etc.), there may be a lot of urine sample remaining on the surface of the reagent strip. When the reagent strip is taken out from the test cup, the urine remaining on the surface of the reagent strip may drip. The dripping urine may no longer react with the reagent layer, which may cause the test result to be low. In addition, if it comes into contact with the non-reactive area of ​​the reagent strip or other test item areas, it may cause cross contamination, resulting in errors in the test results. Utility Model Content

[0005] The utility model discloses a device for testing patient urine, which aims to solve the problem that in the actual operation process, due to the influence of various factors (such as the viscosity of urine, the material of the reagent tape and improper operation, etc.), a large amount of urine sample may remain on the surface of the reagent tape. When the reagent tape is taken out from the detection cup, the urine remaining on the surface of the reagent tape may drip, and the dripping urine may no longer react with the reagent layer, thereby possibly causing a low test result. In addition, if it contacts the non-reactive area of ​​the reagent tape or other test item areas, it may cause cross contamination, resulting in errors in the test results. Technical problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A device for testing urine of a patient, comprising a base frame, two clamping plates and six test cups, and further comprising:

[0008] Liquid suction mechanism: located inside the detection cup, the liquid suction mechanism includes two connecting frames, one side outer wall of the connecting frame is provided with a limit plate, the top outer wall of the limit plate is provided with two slide grooves and a mounting groove, the inner wall of the mounting groove is connected with a threaded rod through a thread, the circumferential outer wall of the threaded rod is fixedly connected with a limit block, the inner wall of the slide groove is slidably connected with a fixed plate, and one side outer wall of the fixed plate is provided with a liquid suction plate;

[0009] Limiting mechanism: located on the circumferential inner wall of the detection cup.

[0010] Before use, the test cup containing the urine sample is placed at the designated position of the urine inspection instrument, and the reagent tape is placed above the test cup through the mechanical structure inside the instrument. When in use, the operator first puts the limiting mechanism on the cup wall of the test cup, and then slides the two fixed plates along the corresponding slide grooves to connect them, and then manually rotates the threaded rod to drive the limiting block to rotate to the top of the fixed plate, thereby limiting the fixed plate. When the reagent tape passes through the two absorbent plates and extends into the inside of the test cup containing urine, due to the presence of the reagent tape's own water absorption layer, the urine can be quickly and evenly distributed on the reagent tape. As the urine is immersed, the various components in the urine begin to react chemically with the reagent layer on the reagent tape, so that the color of the reagent block changes. When the operator pulls up the reagent tape, the urine sample remaining on the surface of the reagent tape is adsorbed by the absorbent plate, and the excess urine sample drips back into the test cup along the inner wall of the fixed plate. The device can effectively prevent the urine sample from dripping into the non-reactive area outside the reagent tape, reduce the error of the test result, and effectively prevent cross contamination.

[0011] In a preferred solution, the liquid absorption plate is an arc-shaped structure, and the two fixed plates form an hourglass-shaped structure.

[0012] The large openings at both ends of the hourglass-shaped fixing plate make it easy for the reagent tape to extend into the interior of the test cup to absorb and react with the urine sample. The small opening in the middle is used in conjunction with the arc-shaped absorbent plate to limit the reagent tape and at the same time enable the absorbent plate to fit tightly against both sides of the reagent tape, thereby facilitating the adsorption of urine samples remaining on the surface of the reagent tape. When the reagent tape is pulled upward, the contact between the residual urine sample and the surface of the reagent tape is increased, so that this part of the urine sample can continue to react with the reagent layer on the reagent tape, making the test results more uniform and accurate.

[0013] In a preferred embodiment, the limiting mechanism includes a mounting ring, the circumferential inner wall of the mounting ring is provided with two adapting grooves, the inner wall of the adapting groove is provided with a mounting plate, the outer wall of one side of the mounting plate is provided with a toothed plate, the bottom outer wall of the connecting frame is provided with two side plates, a gear is connected between the two side plates through a bearing, and the gear is meshed with the toothed plate.

[0014] When in use, first put the mounting ring on the cup wall of the detection cup. Since the gear and the toothed plate are meshed with each other (it should be noted that the meshing connection method between the toothed plate and the gear can also adopt the sliding connection method between the slider and the slide groove), the gear moves on the toothed plate. When the gear moves to the bottom of the toothed plate, the bottom end of the connecting frame is just engaged with the first limit groove, thereby fixing the position of the limit plate.

[0015] As can be seen from the above, a patient urine testing device includes a base frame, two clamping plates and six test cups, and also includes:

[0016] Liquid suction mechanism: located inside the detection cup, the liquid suction mechanism includes two connecting frames, one side outer wall of the connecting frame is provided with a limit plate, the top outer wall of the limit plate is provided with two slide grooves and a mounting groove, the inner wall of the mounting groove is connected with a threaded rod through a thread, the circumferential outer wall of the threaded rod is fixedly connected with a limit block, the inner wall of the slide groove is slidably connected with a fixed plate, and one side outer wall of the fixed plate is provided with a liquid suction plate;

[0017] Limiting mechanism: located on the inner wall of the circumference of the test cup. The patient urine testing device provided by the utility model can effectively prevent the urine sample from dripping into the non-reactive area outside the reagent strip, reduce the error of the test result, and effectively prevent the technical effect of cross contamination.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0025] The utility model discloses a patient urine testing device which is mainly used in actual operation. Due to the influence of various factors (such as the viscosity of urine, the material of the reagent tape and improper operation, etc.), there may be a situation where a lot of urine sample remains on the surface of the reagent tape. When the reagent tape is taken out from the test cup, the urine remaining on the surface of the reagent tape may drip. The dripping urine may no longer react with the reagent layer, which may cause a low test result. Moreover, if it contacts the non-reactive area or other test item area of ​​the reagent tape, it may cause cross contamination, resulting in an error in the test result.

[0026] Reference Figure 1 , Figure 3 and Figure 4 , a patient urine testing device, comprising a base frame 1, two clamping plates 2 and six test cups 3, and also comprising:

[0027] Liquid suction mechanism: located inside the detection cup 3, the liquid suction mechanism includes two connecting frames 7, one side outer wall of the connecting frame 7 is provided with a limit plate 11, the top outer wall of the limit plate 11 is provided with two slide grooves 16 and a mounting groove 17, the inner wall of the mounting groove 17 is connected with a threaded rod 12 through a thread, the circumferential outer wall of the threaded rod 12 is fixedly connected with a limit block 13, the inner wall of the slide groove 16 is slidably connected with a fixed plate 14, and one side outer wall of the fixed plate 14 is provided with a liquid suction plate 15;

[0028] Limiting mechanism: located on the inner circumferential wall of the detection cup 3.

[0029] It should be noted that the liquid absorbing plate 15 is made of elastic water absorbing material, such as sponge, which has strong water absorption.

[0030] Among them, the absorbent plate 15 is an arc-shaped structure, and the two fixed plates 14 form an hourglass-shaped structure. The openings at both ends of the hourglass-shaped fixed plate 14 are large, which is convenient for the reagent tape to extend into the interior of the detection cup 3 to absorb the urine sample and react with it. The opening in the middle is small and is used in conjunction with the arc-shaped absorbent plate 15 to limit the reagent tape. At the same time, the absorbent plate 15 can be tightly attached to the two sides of the reagent tape, so as to facilitate the adsorption of the urine sample remaining on the surface of the reagent tape. When the reagent tape is pulled upward, the contact between the residual urine sample and the surface of the reagent tape is increased, so that this part of the urine sample can continue to react with the reagent layer on the reagent tape, making the test result more uniform and accurate.

[0031] Specifically, before use, the test cup 3 containing the urine sample is placed at the designated position of the urine testing instrument, and the reagent tape is placed above the test cup 3 through the mechanical structure inside the instrument. When in use, the operator first puts the limiting mechanism on the cup wall of the test cup 3, and then slides the two fixing plates 14 along the corresponding slide grooves 16 to connect them, and then manually rotates the threaded rod 12, thereby driving the limiting block 13 to rotate to the top of the fixing plate 14, thereby limiting the fixing plate 14. When the reagent tape passes between the two liquid absorption plates 15 and extends into the inside of the test cup 3 containing urine, Finally, due to the presence of the water-absorbing layer of the reagent tape itself, urine can be quickly and evenly distributed on the reagent tape. As the urine is immersed, the various components in the urine begin to chemically react with the reagent layer on the reagent tape, so that the color of the reagent block changes. When the operator pulls up the reagent tape, the urine sample remaining on the surface of the reagent tape is adsorbed by the absorbent plate 15, and the excess urine sample drips back into the detection cup 3 along the inner wall of the fixed plate 14. This device can effectively prevent the urine sample from dripping into the non-reactive area outside the reagent tape, reduce the error of the test result, and effectively prevent cross contamination.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 In a preferred embodiment, the limiting mechanism includes a mounting ring 5, the circumferential inner wall of the mounting ring 5 is provided with two adapting grooves, the inner wall of the adapting groove is provided with a mounting plate 8, the outer wall of one side of the mounting plate 8 is provided with a tooth plate 9, the bottom outer wall of the connecting frame 7 is provided with two side plates, a gear 10 is connected between the two side plates through a bearing, and the gear 10 is meshed with the tooth plate 9.

[0033] Among them, a support plate is provided on the bottom outer wall of the mounting plate 8, and the length of the mounting plate 8 is the same as the length of the tooth plate 9. The support plate abuts against the bottom of the connecting frame 7, which not only facilitates the limiting of the gear 10, but also supports the bottom of the connecting frame 7.

[0034] In the specific implementation process, a first limiting groove 6 is opened on the top outer wall of the mounting ring 5, one end of the bottom of the connecting frame 7 is clamped on the inner wall of the first limiting groove 6, and the outer walls of both sides of the limiting plate 11 are clamped on the circumferential inner wall of the mounting ring 5.

[0035] The cross section of the mounting ring 5 is an "H"-shaped structure. The mounting ring 5 of the "H"-shaped structure facilitates the simultaneous positioning and fixing of the detection cup 3 and the connecting frame 7, thereby improving the stability of the device.

[0036] During specific use, a second limiting groove is provided on the top outer wall of the connecting frame 7 and close to one side of the limiting plate 11. The second limiting groove is adapted to the limiting block 13. When the fixed plate 14 needs to be replaced, the threaded rod 12 is first rotated 180 degrees in the opposite direction to drive the limiting block 13 to rotate to the inner wall of the second limiting groove. This arrangement avoids blocking the fixed plate 14 from sliding upward for replacement.

[0037] Specifically, when in use, the mounting ring 5 is first sleeved onto the cup wall of the detection cup 3. Since the gear 10 and the tooth plate 9 are meshed with each other (it should be noted that the meshing connection method between the tooth plate 9 and the gear 10 can also adopt a sliding connection method between a slider and a slide groove), the gear 10 moves on the tooth plate 9. When the gear 10 moves to the bottom of the tooth plate 9, one end of the bottom of the connecting frame 7 is just engaged with the first limit groove 6, thereby fixing the position of the limit plate 11.

[0038] Reference Figure 1 In a preferred embodiment, a mounting rod is provided on the top outer wall of the base frame 1, one end of the mounting rod is connected to the bottom outer wall of one of the clamping plates 2 through a bearing, a connecting column is provided between the two clamping plates 2, six equally spaced limit openings are provided on the top outer wall of one of the clamping plates 2, six equally spaced fixed grooves are provided on the top outer wall of one of the clamping plates 2, the detection cup 3 passes through the inner wall of the limit opening and the bottom of the detection cup 3 is matched with the bottom inner wall of the fixing groove, and a trash box 4 is provided on the top outer wall of one of the clamping plates 2.

[0039] Specifically, after the reagent strip adsorbs the urine sample and reacts and is taken out from the test cup 3, the operator can quickly disassemble and remove the fixed plate 14 and the absorbent plate 15 in the absorbent mechanism, and put the used fixed plate 14 and the absorbent plate 15 into the garbage box 4 for collection and cleaning. When the operator tests the urine samples in multiple test cups 3, he only needs to rotate the clamping plate 2. When the clamping plate 2 rotates, it drives the test cup 3 to rotate to the specified position, avoiding the operator walking back and forth, thereby reducing the operator's workload.

[0040] Working principle: Before use, the test cup 3 containing the urine sample is placed at the designated position of the urine testing instrument, and the reagent tape is placed above the test cup 3 through the mechanical structure inside the instrument. When in use, the operator first puts the limiting mechanism on the cup wall of the test cup 3, and then slides the two fixing plates 14 along the corresponding slide grooves 16 to connect them, and then manually rotates the threaded rod 12, thereby driving the limiting block 13 to rotate to the top of the fixing plate 14, thereby limiting the fixing plate 14. When the reagent tape passes through between the two absorbent plates 15 and extends into the inside of the test cup 3 containing urine, due to the presence of the reagent tape's own water absorption layer, the urine can be quickly and evenly distributed on the reagent tape. As the urine is immersed, the various components in the urine begin to react chemically with the reagent layer on the reagent tape, thereby changing the color of the reagent block. When the operator pulls up the reagent tape, the urine sample remaining on the surface of the reagent tape is adsorbed by the absorbent plate 15, and the excess urine sample drips back into the inside of the test cup 3 along the inner wall of the fixing plate 14.

[0041] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
