DETAILED DESCRIPTION

[0034] The following further describes the present application in conjunction with the drawings. It is necessary to point out that the following detailed description is only used to further describe the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0035] The principle of premature rupture of fetal membranes detection for gynecology and obstetrics includes but is not limited to immunoassay, protein marker assay and antibody binding assay. In this scheme, immunoassay is adopted. Based on the principle of immunoassay, monoclonal and polyclonal antibodies are used to detect specific proteins in vaginal secretions. These proteins have a high content in amniotic fluid, but a very low content in normal vaginal secretions. When the fetal membranes rupture, the proteins in the amniotic fluid appear in the vaginal secretions, so the rupture of the fetal membranes can be judged by detecting these proteins.

[0036] The premature rupture of fetal membranes detection using immunoassay usually includes the following steps:

[0037] Step one: insert the collection end 41 into the vagina 5 to 7 cm deep using the sterile collector 4, stay for at least 15 seconds to ensure that the collection end 41 fully collects the sample;

[0038] Step two: put the collection end 41 into the test tube 2 containing buffer, mix evenly to form a test solution;

[0039] Step three: drop the test solution on the droplet area of the test strip 3, the test solution fully reacts with the test strip 3, and finally interpret the result displayed on the test strip 3.

[0040] The control line (C line) on the test strip 3 is visible, the test result is negative, indicating that no fetal membrane rupture is detected; if both the control line (C line) and the test line (AF line) are visible, the test result is positive, indicating that the fetal membrane has ruptured; if no line is visible, or only the test line (AF line) is visible, the test result is invalid, and retesting is required.

[0041] In order to ensure that the sample can be fully mixed with the buffer in a unit of time, thereby improving the detection accuracy, refer to the attached Figures 1 to 4 A fetal membrane rupture detection kit for gynecology and obstetrics includes a box body 1 and a collector 4, the box body 1 is provided with a partition plate 11 and a cover 12, the cover 12 is located above the partition plate 11, and the partition plate 11 and the cover 12 form a refrigeration chamber 13 therebetween;

[0042] The test tube 2 is placed in the refrigeration chamber 13, the test tube 2 is used to hold the dissolving solution, a plurality of extrusion protrusions 21 are fixedly arranged in the test tube 2, the plurality of extrusion protrusions 21 are arranged at equal intervals, and the plurality of extrusion protrusions 21 are all located in the dissolving solution;

[0043] The end of the collector 4 is provided with a collection end 41, the plurality of extrusion protrusions 21 are arranged as an extrusion area, the collection end 41 mixes the sample with the dissolving solution to form a test solution by vertically moving in the extrusion area, the test strip 3 is placed in the box body 1, and the fetal membrane rupture detection is performed by dropping the test solution on the test strip 3.

[0044] It should be noted that, in order to provide a stable operation platform for medical staff, facilitate sample collection, solution mixing and detection operation, and prevent the test solution from deteriorating or being affected by external pollution, the box body 1 is used as the support for other components, or the detection test is completed in the box body 1, transparent cover plates are arranged on the front side and the rear side of the box body 1, the condition of the test tube 2 in the box body 1 can be observed through the transparent cover plates, a cooling fan is arranged in the refrigeration chamber 13, a cooling hole is formed in the box body 1, a power supply module is further arranged in the refrigeration chamber 13, the power supply module is used to supply power for the cooling fan, the cover 12 is movably and detachably arranged in the box body 1, and an ice bag can be added to the refrigeration chamber 13 by detaching the cover 12, thereby assisting to reduce the temperature in the refrigeration chamber 13, and as mature prior art, no further description is given here.

[0045] Further, in order to enable the collection end 41 to collect more samples, the collection end 41 needs to have certain hygroscopic properties, and the collector 4 includes but is not limited to being provided as a medical swab, and the material of the collection end of the medical swab, i.e. the collection end 41, includes but is not limited to being provided as medical cotton, which has good hygroscopicity and softness, can effectively absorb liquid samples, and at the same time has less irritation to the mucous membrane of the patient. The test strip 3 includes a supporting shell, the supporting shell is provided with a sample dropping hole and a display hole, and the supporting shell is provided with a test paper. When in use, the test liquid is added to the dropping hole, and after the test liquid is added to the test paper, the content displayed by the test paper is observed through the display hole. As a mature prior art, it will not be described in detail here.

[0046] It should also be noted that the shape of the extrusion protrusion 21 includes but is not limited to using a hemisphere, and the material of the extrusion protrusion 21 includes but is not limited to using rubber. The distance between the centers of the corresponding two extrusion protrusions 21 is less than the distance between the tops of the corresponding two extrusion protrusions 21, i.e. the distance between the plurality of extrusion protrusions 21 changes with the change in height in the test tube 2. As the horizontal height in the extrusion protrusion 21 decreases, the distance between the plurality of extrusion protrusions 21 becomes smaller. The design of the distance between the plurality of extrusion protrusions 21 changing from large to small facilitates the collection end 41 to move downward and be located between the plurality of extrusion protrusions 21, which can guide the movement of the extrusion protrusion 21. When the collection end 41 moves to the center of the plurality of extrusion protrusions 21, the extrusion protrusion 21 can extrude the collection end 41.

[0047] The implementation scenario is as follows: the test tube 2 is placed in the box body 1, and it is ensured that the test tube 2 is located in the refrigeration chamber 13. The dissolving liquid is added to the test tube 2, and then the collector 4 is held by hand to collect samples through the collection end 41. When the collection end 41 collects enough samples, the collection end 41 will swell compared to the initial state. Then the collector 4 is inserted into the mouth of the test tube 2, so that the collector 4 is located at the center of the mouth of the test tube 2. The collector 4 is moved downward in the test tube 2. When the collection end 41 is located between the plurality of extrusion protrusions 21, the plurality of extrusion protrusions 21 extrude the collection end 41. The extrusion of the collection end 41 by the extrusion protrusion 21 will cause the collection end 41 to deform, and also enable the sample adsorbed in the collection end 41 to be discharged into the dissolving liquid. Then the collection end 41 is moved upward. Due to the extrusion of the collection end 41 by the extrusion protrusion 21 being released, the collection end 41 will adsorb the dissolving liquid in the test tube 2 under the action of the hygroscopic property of the collection end 41. The vertical reciprocating movement of the collection end 41 in the dissolving liquid in the test tube 2 can agitate the dissolving liquid in the test tube 2. In this way, the collector 4 is vertically reciprocated, and the sample in the collection end 41 is fully mixed with the dissolving liquid by the reciprocating extrusion of the collection end 41. Then the test liquid is added to the test strip 3, so as to improve the detection accuracy.

[0048] Compared with the prior art, when the sample is mixed with the dissolving solution, the collecting end 41 is pressed in the dissolving solution, and the collecting end 41 is used to stir the dissolving solution, so that the sample is fully mixed with the dissolving solution, the sample is fully released, the residual sample on the collecting end 41 is reduced, the mixing efficiency is improved, and the accuracy of the detection result is ensured.

[0049] With reference to the description accompanying drawings Figures 1 to 6 To further improve the mixing efficiency between the sample and the dissolving solution, reduce the number of times that the operator vertically moves the collecting end 41 in the test tube 2, and simplify the operation intensity of the worker, specifically, the cover 12 is provided with a placing hole 121, the test tube 2 is placed in the refrigeration chamber 13 through the placing hole 121, the bottom of the cover 12 is provided with an auxiliary driving mechanism 5, the auxiliary driving mechanism 5 includes a sleeve ring 52, the sleeve ring 52 is located below the cover 12, the sleeve ring 52 is concentrically arranged with the placing hole 121, and the sleeve ring 52 is matched with the test tube 2. The auxiliary driving mechanism 5 further includes a fixed seat 51 fixedly arranged at the bottom of the cover 12, the sleeve ring 52 is rotationally arranged with the fixed seat 51, the sleeve ring 52 is provided with a clamping groove 521, the test tube 2 is fixedly provided with a limiting strip 22, and the limiting strip 22 is matched with the clamping groove 521. The sleeve ring 52 is fixedly provided with a gear 53, and the refrigeration chamber 13 is fixedly provided with a rotating driver, and the output shaft of the rotating driver is fixedly provided with a driving tooth, and the driving tooth is engaged with the gear 53.

[0050] It should be noted that the number of placing holes 121 is arranged in pairs as shown in Figure 1 The rotating driver is arranged as an electric motor, the driving tooth is fixedly arranged on the output shaft of the electric motor, the driving tooth is located between the two corresponding gears 53, one driving tooth can drive two gears 53 to rotate, thereby reducing the use of the driving source. The limiting strip 22 is matched with the clamping groove 521, that is, after the limiting strip 22 slides into the clamping groove 521, the test tube 2 can be limited, and the rotation of the sleeve ring 52 can drive the test tube 2 to rotate along the central axis.

[0051] It also needs to be explained that the test tube 2 is put into the refrigeration chamber 13 through the placement hole 121, the limiting strip 22 slides into the clamping groove 521, and then the rotary driver is started. The rotation of the output shaft of the rotary driver drives the driving teeth to rotate, the driving teeth are engaged with the gear 53 to drive the sleeve ring 52 to rotate, the rotation of the sleeve ring 52 drives the test tube 2 to rotate, the extrusion protrusion 21 rotates synchronously with the test tube 2, the vertical reciprocating movement of the collection end 41 in the test tube 2, the rotation of the extrusion protrusion 21 can extrude different positions of the collection end 41, which improves the extrusion efficiency of the collection end 41, and the rotation of the test tube 2 can speed up the flow speed of the dissolving liquid in the test tube 2. The flow of the dissolving liquid in the test tube 2 cooperates with the full extrusion of the test tube 2 to make the sample fully mixed in the dissolving liquid, and can improve the mixing efficiency of the sample and the dissolving liquid, thereby reducing the number of times of the operator vertically moving the collection end 41 in the test tube 2, and simplifying the operation steps of the worker.

[0052] Referring to the description Figures 5 to 7 When the sample and the dissolving liquid are fully mixed to form a test solution, the test tube 2 needs to be taken out to drop the test solution on the test strip 3, or a dropper is used to transfer and drop the test solution on the test strip 3. In order to simplify the dropping steps and improve the dropping efficiency, specifically, a separation layer one 23 is fixedly arranged in the test tube 2, a droplet mechanism 6 is arranged in the test tube 2, the droplet mechanism 6 includes a guide seat 63 fixedly arranged on the separation layer one 23, a connecting barrel 62 is slidably arranged on the guide seat 63, a moving seat 61 is fixedly arranged on the top of the connecting barrel 62, an elastic element 64 is arranged between the connecting barrel 62 and the guide seat 63, a through hole one 621 is formed in the connecting barrel 62, a through hole two 631 is formed in the guide seat 63, the through hole one 621 and the through hole two 631 are matched, and the liquid discharge end of the through hole two 631 extends to the outside of the test tube 2 and is located directly above the test strip 3. The cover 14 is hingedly arranged on the partition plate 11, the positioning hole 15 is formed in the box body 1, and the test strip 3 is matched with the positioning hole 15.

[0053] It should be noted that the elastic element 64 is a spring, the top end of the spring is fixedly arranged with the connecting barrel 62, and the bottom end of the spring is fixedly arranged with the guide seat 63. A limiting seat is fixedly arranged in the test tube 2, the limiting seat is located above the moving seat 61 and abuts with the top of the moving seat 61. The extrusion protrusion 21 is located above the limiting seat. The liquid discharge end of the through hole two 631 is located at the center of the bottom of the test tube 2, so that even if the test tube 2 rotates, there will be no positional deviation between the test tube 2 and the test strip 3.

[0054] It also needs to be explained that the test strip 3 is placed in the corresponding positioning hole 15, and during the vertical movement of the collection end 41 in the test tube 2, the collection end 41 is extruded by the extrusion protrusion 21 to fully mix the sample and the dissolving solution. When the mixing is completed, the test solution is added on the test strip 3, the collection end 41 is moved downward, the collection end 41 is moved below the plurality of extrusion protrusions 21, and then the collection end 41 is pressed downward to move the moving seat 61. The driving connecting cylinder 62 of the moving seat 61 moves downward, and the elastic member 64 is elastically deformed during the downward movement of the connecting cylinder 62. When the through hole one 621 communicates with the through hole two 631, the test solution in the test tube 2 is discharged through the discharge end of the through hole two 631 to the test strip 3, and then the collection end 41 is moved upward. The moving seat 61 is reset under the action of the elasticity of the elastic member 64, the through hole one 621 and the through hole two 631 are out of position and no longer communicate, and the effect of automatically adding the test solution is achieved. The test solution does not need to be removed from the test tube 2 or transferred by a dropper. It only needs to press the moving seat 61 downward to discharge the test solution. The time for pressing the moving seat 61 downward is 1-2 seconds. The operation steps are simplified and the dripping efficiency is improved.

[0055] The moving seat 61 is pressed downward, the pressing time is 1-2 seconds, the test solution is discharged through the through hole two 631, and if the operator presses the moving seat 61 downward for too long due to operation error, too much test solution will be discharged through the through hole two 631. Too much test solution added on the test strip 3 will reduce the detection sensitivity of the test strip 3, thereby affecting the accuracy of the detection result. In order to avoid this situation, refer to the drawings in the specification Figures 5 to 8 , specifically, the test tube 2 is fixedly provided with a second isolation layer 24, the first isolation layer 23 and the second isolation layer 24 are arranged as a discharge area 25, the second isolation layer 24 and the bottom inner wall of the test tube 2 are arranged as a buffer area 26, the test tube 2 is fixedly provided with a capillary one 66, the through hole two 631 is fixedly communicated with a liquid discharge pipe 65, the bottom end of the liquid discharge pipe 65 is located in the discharge area 25, the top end of the capillary one 66 is located in the discharge area 25, the bottom end of the capillary one 66 extends below the test tube 2, and the test strip 3 is located directly below the capillary one 66. A plurality of capillary twos 67 are fixedly arranged on the second isolation layer 24, the top ends of the plurality of capillary twos 67 are higher than the top end of the capillary one 66, and the diameters of the plurality of capillary twos 67 are greater than the diameter of the capillary one 66. The test tube 2 is fixedly communicated with a capillary three 68 and a capillary four 69, the bottom end of the capillary three 68 is located in the discharge area 25, the bottom end of the capillary four 69 is located in the buffer area 26, the top ends of the capillary three 68 and the capillary four 69 are fixedly communicated with the test tube 2, and the top ends of the capillary three 68 and the capillary four 69 are located above the liquid level of the test solution in the test tube 2.

[0056] It should be noted that the drain pipe 65 is provided in Y-shaped structure to avoid the test solution discharged from the bottom end of the drain pipe 65 directly falling on the top end of the capillary tube one 66 or the capillary tube two 67. The lengths of the plurality of capillary tube twos 67 are different, that is, the horizontal heights of the plurality of capillary tube twos 67 are different, but the horizontal heights of the top ends of the plurality of capillary tube twos 67 are higher than the horizontal height of the top end of the capillary tube one 66. The design of the capillary tube three 68 avoids forming a closed cavity in the discharge area 25, and at the same time can discharge the excess test solution in the discharge area 25 into the test tube 2; the design of the capillary tube four 69 avoids forming a closed cavity in the buffer area 26, and at the same time can discharge the excess test solution in the buffer area 26 into the test tube 2, and the bottom end of the capillary tube three 68 is higher than the highest position of the capillary tube two 67 in the discharge area 25 to avoid the capillary tube three 68 directly conveying the test solution in the discharge area 25. The principle of capillary water absorption and water transport is the automatic rising phenomenon of liquid in the capillary tube due to surface tension, adhesion and meniscus effect, which has wide application in nature and industry, and as a mature prior art, it will not be described in detail here. It is worth mentioning that one of the plurality of capillary tube twos 67 can also be provided at the same horizontal position as the top end of the capillary tube one 66.

[0057] It should also be noted that after pressing the moving seat 61 downward, the test solution in the moving seat 61 enters the discharge area 25 through the drain pipe 65, and under normal circumstances, the operator presses the moving seat 61 for 1-2 seconds and then the moving seat 61 automatically resets. With the increase of the test solution in the discharge area 25, the liquid level of the test solution in the discharge area 25 is higher than that of the capillary tube one 66, the top end of the capillary tube one 66 absorbs the test solution, and the bottom end of the capillary tube one 66 discharges the test solution onto the test strip 3. If the operator operates incorrectly and presses the moving seat 61 for too long, the liquid level of the test solution in the discharge area 25 is higher than the abnormal amount, and then the capillary tube three 68 will absorb the excess test solution in the discharge area 25 and discharge it into the test tube 2. In combination with the top end of the plurality of capillary tube twos 67 absorbing the test solution in the discharge area 25 in the initial stage, the test solution in the discharge area 25 is transported into the buffer area 26. Since the diameter of the capillary tube two 67 is larger than that of the capillary tube one 66, the capillary tube two 67 can quickly reduce the height of the liquid level in the discharge area 25 in a short time, so that the liquid level in the discharge area 25 changes rapidly to discharge the excess test solution, ensuring that the amount of test solution discharged on the test strip 3 is 3-4 drops, avoiding excessive test solution being discharged from the bottom end of the capillary tube one 66 onto the test strip 3, and ensuring that the detection result is not affected.

[0058] The test tube 2, the collector 4 and the capillary tube one 66 and other components are disposable medical devices, which are convenient to replace and more sanitary through the design of the test tube 2 and the capillary tube one 66.

[0059] Referring to the drawings Figure 5 With Figure 9In the process of vertically moving the collection end 41 in the test tube 2, in order to be able to vertically position the test tube 2 and avoid the movement of the test tube 2 when the collection end 41 is lifted, specifically, the cam 7 is rotationally arranged on the buckle 12, the cam 7 is in contact with the top end of the test tube 2 after rotation, and the cam 7 is used for vertically limiting the test tube 2. The bottom of the cam 7 is provided with a groove, and the groove is provided with a ball which rolls, and the ball is used to reduce the friction between the test tube 2 and the top end. In the process of rotating the test tube 2, the ball is in rolling contact with the top end of the test tube 2 to reduce the friction, so as to avoid the test tube 2 from rotating and causing the cam 7 to deviate and release the vertical positioning of the test tube 2.

[0060] It should be noted that the cam 7 is rotated to make the cam 7 contact the top end of the test tube 2, and the position where the cam 7 contacts the test tube 2 does not affect the rotation of the test tube 2. The cam 7 generates vertical positioning of the test tube 2. When the test tube 2 needs to be taken out, the cam 7 only needs to be rotated again to release the positioning of the test tube 2. Each cam 7 can position two test tubes 2.

[0061] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application.
