Description

Technical Field

[0001] The present invention relates to the technical field of detection kits, and more particularly to a detection kit for premature rupture of membranes for obstetrics and gynecology. Background Art

[0002] Premature rupture of membranes refers to the rupture of the fetal membranes before delivery. This may lead to serious complications such as premature birth and infection. Therefore, timely and accurate diagnosis is crucial. The premature rupture of membranes detection kit for obstetrics and gynecology is a medical detection tool used to quickly and accurately diagnose whether the fetal membranes have ruptured prematurely.

[0003] When testing for premature rupture of membranes, you first need to collect a sample. To ensure the accuracy of the sample, insert the collecting end of the collector into the pregnant woman's vagina to collect the sample. To ensure that the collecting end of the collector can absorb more samples and prevent the sample from being easily lost, thereby improving the accuracy of the test, the collecting end of the collector has a certain degree of hygroscopicity. After the sample collection is completed, the sample collected by the collecting end of the collector is placed in the dissolving solution. The dissolving solution is stirred by the collector to fully mix the sample and the dissolving solution to form a test solution. Finally, the test solution is dropped onto the test strip and the result displayed on the test line on the test strip is observed.

[0004] However, since the collection end of the collector has a certain degree of hygroscopicity, after the collection end is placed in the dissolving solution, the sample may be partially adsorbed by the collection end and difficult to be completely released into the dissolving solution, resulting in insufficient sample amount in the test solution and affecting the test results. Summary of the Invention

DETAILED DESCRIPTION

[0030] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] The principles of premature rupture of membranes detection in obstetrics and gynecology include but are not limited to immunoassays, protein marker assays, and antibody binding assays. This protocol uses immunoassays, which are based on the principles of immunoassays and use monoclonal and polyclonal antibodies to detect specific proteins in vaginal secretions. These proteins are present in high levels in amniotic fluid but are extremely low in normal vaginal secretions. When the membranes rupture, the proteins in the amniotic fluid will appear in the vaginal secretions. Therefore, the presence of these proteins can be used to determine whether the membranes have ruptured.

[0032] Testing for premature rupture of membranes using an immunoassay typically involves the following steps: Step 1: Use the sterile collector 4 to insert the collection end 41 into the vagina 5 to 7 cm deep, and stay there for at least 15 seconds to ensure that the collection end 41 fully collects the sample; Step 2: Place the collection end 41 into the test tube 2 containing the buffer solution and mix evenly to form a test solution; Step 3: Drop the test solution on the dripping area of ​​the test strip 3. The test solution and the test strip 3 will fully react, and the result displayed on the test strip 3 can be finally interpreted.

[0033] If the control line (C line) on test strip 3 is visible, the test result is negative, indicating that no rupture of membranes is detected; if both the control line (C line) and the test line (AF line) are visible, the test result is positive, indicating rupture of membranes; if no line is visible, or only the test line (AF line) is visible, the test result is invalid and needs to be retested.

[0034] In order to ensure that the sample can be fully mixed with the buffer solution within a unit time, thereby improving the detection accuracy, refer to the instructions for Figures 1 to 4 A premature rupture of membranes detection kit for obstetrics and gynecology, comprising a box body 1 and a collector 4, wherein a partition 11 and a buckle cover 12 are provided in the box body 1, the buckle cover 12 is located above the partition 11, and a refrigeration chamber 13 is provided between the partition 11 and the buckle cover 12; A test tube 2 is placed in the cold storage chamber 13. The test tube 2 is used to hold the dissolved liquid. A plurality of extrusion protrusions 21 are fixedly provided in the test tube 2. The plurality of extrusion protrusions 21 are arranged at equal intervals. The plurality of extrusion protrusions 21 are all located in the dissolved liquid. A collecting end 41 is provided at the end of the collector 4, and an extrusion area is set between the multiple extrusion protrusions 21. The collecting end 41 mixes the sample and the dissolving liquid to form a test solution by vertically moving in the extrusion area. A test strip 3 is placed in the box body 1, and premature rupture of membranes is detected by dripping the test solution onto the test strip 3.

[0035] It should be noted that in order to provide medical staff with a stable operating platform, facilitate sample collection, solution mixing and detection operations, and in order to prevent the test solution from deteriorating or being affected by external contamination, the box body 1 is used as a support for other components, or the detection test is completed in the box body 1, and transparent covers are provided on the front and rear sides of the box body 1. The situation of the test tube 2 in the box body 1 can be observed through the transparent cover. A cooling fan is provided in the cold storage chamber 13, and heat dissipation holes are opened on the box body 1. A power supply module is also provided in the cold storage chamber 13, and the power supply module is used to power the cooling fan. The buckle cover 12 is movably and detachably arranged in the box body 1, and an ice pack can also be added to the cold storage chamber 13 by removing the buckle cover 12, thereby assisting in lowering the temperature in the cold storage chamber 13. As a mature existing technology, we will not go into details here.

[0036] Furthermore, in order for the collection end 41 to collect more samples, the collection end 41 needs to have certain hygroscopic properties. The collector 4 includes, but is not limited to, a medical swab. The material of the collection end of the medical swab, i.e., the collection end 41, includes, but is not limited to, medical cotton. Medical cotton has good hygroscopicity and softness, can effectively absorb liquid samples, and is less irritating to the patient's mucous membrane. The test strip 3 includes a supporting housing, which is provided with a sample dripping hole and a display hole. The support housing is provided with a test strip. During use, the test solution is dripped into the dripping hole. After the test solution is dripped onto the test strip, the content displayed on the test strip is observed through the display hole. As a mature existing technology, it will not be described in detail here.

[0037] It should also be noted that the shape of the extrusion protrusion 21 includes but is not limited to a hemispherical shape, the material of the extrusion protrusion 21 includes but is not limited to rubber, and the distance between the centers of two corresponding extrusion protrusions 21 is smaller than the distance between the tops of two corresponding extrusion protrusions 21, that is, the distance between multiple extrusion protrusions 21 changes with the change of height in the test tube 2, and as the horizontal height in the extrusion protrusion 21 decreases, the distance between multiple extrusion protrusions 21 becomes smaller. The design of the distance between multiple extrusion protrusions 21 changing from large to small makes it easier for the collection end 41 to be located between multiple extrusion protrusions 21 during the downward movement, and can guide the movement of the extrusion protrusion 21. When the collection end 41 moves to the center of the multiple extrusion protrusions 21, the extrusion protrusion 21 can squeeze the collection end 41.

[0038] The specific implementation scenario is as follows: place the test tube 2 in the box body 1, and ensure that the test tube 2 is located in the cold storage chamber 13, add the dissolving liquid into the test tube 2, and then use the handheld collector 4 to collect the sample through the collecting end 41. When the collecting end 41 collects enough samples, the collecting end 41 will expand to a certain extent compared with the initial state, and then insert the collector 4 into the tube mouth of the test tube 2, so that the collector 4 is located at the center of the tube mouth of the test tube 2, and move the collector 4 downward in the test tube 2. When the collecting end 41 is located between the multiple squeezing protrusions 21, the multiple squeezing protrusions 21 squeeze the collecting end 41, and the squeezing protrusions 21 squeeze the collecting end 41. The end 41 will cause the collecting end 41 to deform, and can also discharge the sample adsorbed in the collecting end 41 into the dissolving liquid, and then move the collecting end 41 upward. Since the squeezing protrusion 21 releases the squeezing of the collecting end 41, the collecting end 41 will adsorb the dissolving liquid in the test tube 2 under the action of the hygroscopic property of the collecting end 41. The collecting end 41 moves back and forth vertically in the dissolving liquid in the test tube 2 to stir the dissolving liquid in the test tube 2. In this way, the collector 4 is moved back and forth vertically, and the sample in the collecting end 41 is fully mixed with the dissolving liquid by re-squeezing the collecting end 41, and then the test liquid is dripped onto the test strip 3, thereby improving the detection accuracy.

[0039] Compared with the existing technology, when mixing the sample and the dissolving liquid, the collection end 41 is squeezed in the dissolving liquid, and the dissolving liquid is stirred with the collection end 41 to achieve sufficient mixing of the sample and the dissolving liquid. This not only allows the sample to be fully released, reduces the sample residue on the collection end 41, improves the mixing efficiency, but also ensures the accuracy of the test results.

[0040] Refer to the instruction manual Figures 1 to 6 To further improve the efficiency of mixing between the sample and the dissolving solution, reduce the number of times the operator needs to vertically lower the collection end 41 within the test tube 2, and simplify the operator's operating intensity, specifically, a placement hole 121 is defined on the buckle cover 12, through which the test tube 2 is placed within the refrigerated chamber 13. An auxiliary drive mechanism 5 is provided at the bottom of the buckle cover 12. The auxiliary drive mechanism 5 includes a collar 52, which is located below the buckle cover 12 and is concentrically disposed with the placement hole 121 and adapted to fit within the test tube 2. The auxiliary drive mechanism 5 also includes a fixed base 51, which is fixedly disposed at the bottom of the buckle cover 12. The collar 52 is rotatably disposed relative to the fixed base 51. A slot 521 is defined on the collar 52, and a limit bar 22 is fixedly disposed on the test tube 2, which is adapted to fit within the slot 521. A gear 53 is fixedly provided on the collar 52 , a rotary driver is fixedly provided in the refrigerating chamber 13 , and a driving tooth is fixedly provided on the output shaft of the rotary driver, and the driving tooth is meshed with the gear 53 .

[0041] It should be noted that the number of placement holes 121 is as follows: Figure 1 As shown in FIG, the two corresponding gears 53 are arranged in pairs, and the rotation driver is configured as a motor. The driving teeth are fixedly mounted on the output shaft of the motor and located between the two corresponding gears 53. One driving tooth can drive both gears 53 to rotate, thereby reducing the use of a driving source. The limiting strip 22 is adapted to the retaining groove 521. That is, after the limiting strip 22 slides into the retaining groove 521, it can limit the position of the test tube 2. At the same time, the rotation of the collar 52 can drive the test tube 2 to rotate along its central axis.

[0042] It should also be noted that the test tube 2 is placed in the cold storage chamber 13 through the placement hole 121, so that the limit bar 22 slides into the card slot 521, and then the rotary drive is started. The rotation of the rotary drive output shaft causes the driving gear to rotate, and the driving gear engages with the gear 53 to rotate the transmission ring 52. The rotation of the ring 52 drives the test tube 2 to rotate, and the squeezing protrusion 21 rotates synchronously with the test tube 2, and the collection end 41 is moved vertically back and forth in the test tube 2. The rotation of the squeezing protrusion 21 can squeeze different positions of the collection end 41, thereby improving the squeezing efficiency of the collection end 41, and the rotation of the test tube 2 can accelerate the flow rate of the dissolved liquid in the test tube 2. The flow of the dissolved liquid in the test tube 2 and the sufficient squeezing of the test tube 2 can fully mix the sample in the dissolved liquid and improve the mixing efficiency of the sample and the dissolved liquid, thereby reducing the number of times the operator moves the collection end 41 vertically in the test tube 2 and simplifying the operating steps of the staff.

[0043] Refer to the instruction manual Figures 5 to 7 , when the sample and the dissolving liquid are fully mixed to form a test solution, it is necessary to take out the test tube 2 and drip the test solution onto the test strip 3, or use a dropper to transfer the test solution and drip it onto the test strip 3. In order to simplify the dripping steps and improve the dripping efficiency, specifically, an isolation layer 23 is fixedly provided in the test tube 2, and a dripping mechanism 6 is provided in the test tube 2. The dripping mechanism 6 includes a guide seat 63, which is fixedly provided on the isolation layer 23. A connecting tube 62 is slidably provided on the guide seat 63, and a movable seat 61 is fixedly provided on the top of the connecting tube 62. An elastic member 64 is provided between the connecting tube 62 and the guide seat 63. A through hole 1 621 is provided on the connecting tube 62, and a through hole 2 631 is provided on the guide seat 63. The through hole 1 621 is adapted to the through hole 2 631. The discharge end of the through hole 2 631 extends to the outside of the test tube 2 and is located directly above the test strip 3. The partition 11 is hingedly provided with a box cover 14 , and the box body 1 is provided with a positioning hole 15 , and the test strip 3 is adapted to fit into the positioning hole 15 .

[0044] It should be noted that the elastic member 64 is configured as a spring, the top end of which is fixed to the connecting tube 62, and the bottom end of which is fixed to the guide seat 63. A limit seat is fixedly disposed within the test tube 2, located above and abutting against the top of the movable seat 61. The extrusion protrusion 21 is located above the limit seat. The discharge end of the second through-hole 631 is located at the center of the bottom of the test tube 2, ensuring that the test tube 2 does not deviate from the test strip 3 even if the test tube 2 rotates.

[0045] It should also be noted that the test strip 3 is placed in the corresponding positioning hole 15. During the vertical movement of the collecting end 41 in the test tube 2, the collecting end 41 and the squeezing protrusion 21 are squeezed to fully mix the sample and the dissolved liquid. When the mixing is completed and the test liquid is to be dripped onto the test strip 3, the collecting end 41 is moved downward to the bottom of the multiple squeezing protrusions 21, and then the collecting end 41 is pressed downward on the moving seat 61. The driving connecting cylinder 62 of the moving seat 61 moves downward. During the downward movement of the connecting cylinder 62, the elastic member 64 is elastically deformed. When the tube 62 is pulled downward, the elastic member 64 is deformed. After the first hole 621 is connected with the second through hole 631, the test liquid in the test tube 2 is discharged onto the test strip 3 through the discharge end of the second through hole 631, and then the collection end 41 is moved upward. Under the action of the elastic force of the elastic member 64, the movable seat 61 is reset, and the first through hole 621 and the second through hole 631 are misaligned and no longer connected, thereby achieving the effect of automatically dripping the test liquid. There is no need to remove the test tube 2 or use a dropper to transfer the test liquid. The test liquid can be discharged by simply pressing the movable seat 61 downward, and the time for pressing the movable seat 61 downward is 1 to 2 seconds, which simplifies the operation steps and improves the dripping efficiency.

[0046] Press the movable seat 61 downward for 1 to 2 seconds to discharge the test solution through the second through hole 631. If the operator presses the movable seat 61 downward for too long due to an operation error, too much test solution will be discharged through the second through hole 631. Excessive test solution dripped onto the test strip 3 will cause the test sensitivity of the test strip 3 to decrease, thereby affecting the accuracy of the test result. To avoid this situation, refer to the attached manual. Figures 5 to 8 Specifically, a second isolation layer 24 is fixedly installed within the test tube 2. A drainage area 25 is defined between the first isolation layer 23 and the second isolation layer 24. A buffer area 26 is defined between the second isolation layer 24 and the bottom inner wall of the test tube 2. A first capillary tube 66 is fixedly installed on the test tube 2. A drainage tube 65 is fixedly connected to the second through-hole 631. The bottom end of the drainage tube 65 is located within the drainage area 25, and the top end of the first capillary tube 66 is located within the drainage area 25. The bottom end of the first capillary tube 66 extends below the test tube 2, and the test strip 3 is located directly below the first capillary tube 66. Multiple sets of second capillary tubes 67 are fixedly installed on the second isolation layer 24. The top ends of the multiple sets of second capillary tubes 67 are all higher than the top ends of the first capillary tube 66, and the diameters of the multiple sets of second capillary tubes 67 are all larger than the diameter of the first capillary tube 66. Capillary tube 3 68 and capillary tube 4 69 are fixedly connected to test tube 2. The bottom end of capillary tube 3 68 is located in the discharge area 25, and the bottom end of capillary tube 4 69 is located in the buffer area 26. The top ends of capillary tube 3 68 and capillary tube 4 69 are both fixedly connected to test tube 2, and the top ends of capillary tube 3 68 and capillary tube 4 69 are both located above the liquid surface of the test solution in test tube 2.

[0047] It should be noted that the drain tube 65 is configured as a Y-shaped structure to prevent the test liquid discharged from the bottom end of the drain tube 65 from directly falling on the top of capillary tube 1 66 or capillary tube 2 67. The lengths of the multiple sets of capillary tube 2 67 are different, that is, the horizontal heights of the multiple sets of capillary tube 2 67 are different, but the horizontal heights of the top ends of the multiple sets of capillary tube 2 67 are all higher than the horizontal height of the top ends of capillary tube 1 66. The design of capillary tube 3 68 prevents the formation of a closed cavity in the discharge area 25, while allowing the excess test liquid in the discharge area 25 to be discharged back into the test tube 2. The design of capillary tube 4 69 prevents the formation of a closed cavity in the buffer area 26, while allowing the excess test liquid in the buffer area 26 to be discharged back into the test tube 2. The bottom end of capillary tube 3 68 is located in the discharge area 25 at a higher position than the highest point of capillary tube 2 67, preventing capillary tube 3 68 from directly transporting the test liquid in the discharge area 25. The principle of capillary water absorption and transfer is the automatic rise of liquid within the capillary due to surface tension, adhesion, and the meniscus effect. This phenomenon is widely used in nature and industry, and as a mature existing technology, it will not be elaborated on here. It is worth mentioning that one of the multiple sets of capillary tubes 67 can also be arranged so that the top of capillary tube 1 66 is at the same horizontal plane.

[0048] It should also be noted that after the movable seat 61 is pressed downward, the test liquid in the movable seat 61 enters the discharge area 25 through the drain pipe 65. Under normal circumstances, the operator presses the movable seat 61 downward, and the movable seat 61 automatically resets after 1 to 2 seconds. As the test liquid in the discharge area 25 increases, the test liquid level in the discharge area 25 is higher than the capillary 1 66. The top of the capillary 1 66 absorbs the test liquid, and the bottom of the capillary 1 66 discharges the test liquid onto the test strip 3. If the operator makes an error and presses the movable seat 61 for too long, which causes the test liquid level in the discharge area 25 to be higher than the abnormal amount, then the capillary 1 68 It will absorb the excess test liquid in the discharge area 25 and discharge it into the test tube 2. In cooperation with the top ends of the multiple capillaries 67, the capillaries 67 initially absorb the test liquid in the discharge area 25 and transfer the test liquid in the discharge area 25 to the buffer zone 26. Since the diameter of the capillary 67 is larger than that of the capillary 1 66, the capillary 67 can quickly lower the height of the liquid level in the discharge area 25 in a short period of time, so that the liquid level in the discharge area 25 changes rapidly to discharge the excess test liquid, ensuring that the amount of test liquid discharged on the test strip 3 is 3 to 4 drops, and preventing the bottom end of the capillary 1 66 from discharging excessive test liquid onto the test strip 3, thereby ensuring that the test results are not affected.

[0049] The test tube 2, collector 4 and capillary tube 66 are all disposable medical devices. The design of the test tube 2 and capillary tube 66 makes replacement easy and more hygienic.

[0050] Refer to the instruction manual Figure 5 and Figure 9During the vertical movement of the collection end 41 within the test tube 2, in order to vertically position the test tube 2 and prevent it from moving when the collection end 41 is lifted, a cam 7 is rotatably mounted on the buckle cover 12. After rotation, the cam 7 engages the top of the test tube 2, thereby limiting the vertical position of the test tube 2. A groove is defined at the bottom of the cam 7, within which a ball bearing rolls, reducing friction with the top of the test tube 2. As the test tube 2 rotates, the ball bearing rolls against the top of the test tube 2, reducing friction and preventing the cam 7 from shifting during rotation, thereby releasing the vertical position of the test tube 2.

[0051] It should be noted that the cam 7 is rotated so that it contacts the top of the test tube 2. The position where the cam 7 contacts the test tube 2 does not affect the rotation of the test tube 2. The cam 7 vertically positions the test tube 2. When the test tube 2 needs to be removed, the cam 7 can be rotated again to release the positioning of the test tube 2. Each cam 7 can position two test tubes 2.

[0052] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
