Description
Technical Field
[0001] This utility model relates to the field of pregnancy testing technology, specifically to a pregnancy testing device for obstetrics and gynecology. Background Technology
[0002] In daily life, women can easily conduct early pregnancy tests at home using tools such as pregnancy test strips without professional operation. In hospital obstetrics and gynecology departments, these devices are also often used for rapid screening during initial consultations to provide a reference for subsequent diagnosis and treatment. When using traditional pregnancy test devices, it is usually necessary to immerse the urine absorption area of the test strip in urine or directly collect urine. The urine is allowed to penetrate upwards by the capillary action of the test strip itself, and the result is judged by the color development of the test area and the control area. However, the penetration speed of urine is not always stable. Insufficient penetration can lead to insufficient reaction in the test area, or excessive penetration can cause urine to overflow and contaminate the hands. In addition, the amount of urine absorbed in the absorption area is difficult to control. Too much urine can dilute the antibodies, or too little urine can fail to cover the test area, thus affecting the accuracy and efficiency of the test. In view of this, we propose a pregnancy testing device for obstetrics and gynecology. Utility Model Content
[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a pregnancy test device for obstetrics and gynecology, which can effectively solve the problems of unstable urine penetration rate and difficulty in controlling urine absorption volume in the existing pregnancy test devices, which affect the accuracy and efficiency of the test and easily contaminate the hands.
[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a pregnancy testing device for obstetrics and gynecology, including a main body, including a shell, a sleeve disposed on the shell for engaging the urine inlet position of the shell, and a test strip disposed inside the shell; The urinary catheterization mechanism includes a pressing block on the housing, a trapezoidal block one located below the pressing block, a trapezoidal block two located on one side of the trapezoidal block one for pressing and engaging with the trapezoidal block one, a piston cylinder one located on one side of the trapezoidal block two for aspirating urine, two sets of release cylinders located below the test strip, an air bladder ring located inside the two sets of release cylinders, and a piston cylinder two located on the side of the trapezoidal block two away from the piston cylinder one. The piston cylinder two can be used to inflate and deflate the air bladder ring.
[0005] Furthermore, one end of the housing is snapped into the inner wall of the sleeve, and the surface of the test strip is fixedly connected to the inner wall of the housing. The test strip can be divided into a detection area and a control area.
[0006] Furthermore, the pressing block is slidably connected to the inner wall of the housing, the bottom of the pressing block is fixedly connected to the top of the trapezoidal block, and the surface of the trapezoidal block is slidably connected to the inner wall of the housing.
[0007] Furthermore, the bottom of trapezoidal block two is slidably connected to the inner wall of the housing, a spring is fixedly connected to one side of trapezoidal block two, the end of the spring away from trapezoidal block two is fixedly connected to one side of piston cylinder one, and the surface of piston cylinder one is fixedly connected to the inner wall of the housing.
[0008] Furthermore, a rubber piston is fitted onto the inner wall of piston cylinder one, and one side of the rubber piston one is fixedly connected to the side of trapezoidal block two near the spring via piston rod two.
[0009] Furthermore, one end of the piston cylinder is fixedly connected to a suction nozzle via a catheter. The surfaces of both the suction nozzle and the catheter are fixedly connected to the inner wall of the housing, and the catheter communicates with the two sets of release cylinders.
[0010] Furthermore, a piston rod is fixed to the side of the trapezoidal block two away from the spring, and a rubber piston is fixedly connected to the end of the piston rod one away from the trapezoidal block two.

The surfaces of both sets of airbag rings are fixedly connected to the inner wall of the release cylinder.
[0012] The technical solution provided by this utility model has the following advantages compared with the known public technology: This invention uses mechanical transmission to control the extraction and release of urine, ensuring accurate delivery of urine to the detection and control areas of the test strip. This avoids insufficient reaction caused by uneven penetration, significantly reducing the probability of false negatives or false positives. The test can be completed with simple pressing and flipping, simplifying the process. Even non-professionals can quickly get started, making it especially suitable for home testing. When not in use, it effectively isolates dust and contaminants, and during use, it prevents urine leakage, reducing the risk of hand contact contamination, thus balancing hygiene and safety. The linkage components achieve coordinated operation of urine extraction, sealing, and release, with stable cooperation between components, reducing errors caused by improper operation and effectively improving the accuracy and efficiency of the device.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0017] The present invention will be further described below with reference to the embodiments.
[0018] A pregnancy testing device for obstetrics and gynecology includes a main body 100, comprising a housing 101, a sleeve 102 disposed on the housing 101 for engaging the urine inlet of the housing 101, and a test strip 103 disposed inside the housing 101. One end of the housing 101 is engaged with the inner wall of the sleeve 102, and the surface of the test strip 103 is fixedly connected to the inner wall of the housing 101. The test strip 103 can be divided into a detection area and a control area. The housing 101 serves as the main frame of the device, providing installation and protection space for the internal components. The sleeve 102 engages with the urine inlet of the housing 101 to protect the urine inlet and prevent urine leakage from contaminating the interior of the housing 101. It should be noted that the test strip 103 is fixedly connected to the inner wall of the housing 101 through a connecting structure such as a test strip box. Its position corresponds to the urine flow path and can receive urine entering the device. The detection area and control area on the test strip 103 are the core reaction areas. When urine flows through the test strip 103, the detection area will have a specific reaction with HCG in the urine, and the control area will have a corresponding reaction to confirm the validity of the test. Finally, the color development of the two areas is used to determine whether pregnancy has occurred. Furthermore, the urine catheterization mechanism 200 includes a pressing block 201 disposed on the housing 101, a trapezoidal block 204 disposed below the pressing block 201, a trapezoidal block 205 disposed on one side of the trapezoidal block 204 for pressing and engaging with the trapezoidal block 204, a piston cylinder 202 disposed on one side of the trapezoidal block 205 for drawing urine, two sets of release cylinders 2011 disposed below the test strip 103, an air bladder ring 2015 disposed inside the two sets of release cylinders 2011, and a piston cylinder 203 disposed on the side of the trapezoidal block 205 away from the piston cylinder 202. The piston cylinder 203 can be used to inflate and deflate the air bladder ring 2015. The main function of the urine catheterization mechanism 200 is to accurately deliver urine to the detection area and control area of the test strip 103. Specifically, the pressing block 201 is slidably connected to the inner wall of the housing 101. The bottom of the pressing block 201 is fixedly connected to the top of the trapezoidal block 204. The surface of the trapezoidal block 204 is slidably connected to the inner wall of the housing 101. The bottom of the trapezoidal block 205 is slidably connected to the inner wall of the housing 101. A spring 2010 is fixedly connected to one side of the trapezoidal block 205. The end of the spring 2010 away from the trapezoidal block 205 is fixedly connected to one side of the piston cylinder 202. The surface of the piston cylinder 202 is fixedly connected to the inner wall of the housing 101. A rubber piston 2013 is sleeved on the inner wall of the piston cylinder 202. The piston rod 2012 is fixedly connected to the trapezoidal block 205 near the spring 2010. One end of the piston cylinder 202 is fixedly connected to the suction nozzle 207 via the catheter 206. The surfaces of the suction nozzle 207 and the catheter 206 are fixedly connected to the inner wall of the housing 101, and the catheter 206 communicates with the two sets of release cylinders 2011. The suction nozzle 207 is fixed to the inner wall of the housing 101 and is located at the urine inlet end of the housing 101. When the sleeve 102 covers one end of the housing 101, the sealing gasket inside the sleeve 102 can block the urine inlet end of the suction nozzle 207, preventing the catheter 206 and other catheterization components from being contaminated. It should be noted that, during use, the urine inlet end of the housing 101 can be inserted into the container containing urine first, so that the suction nozzle 207 can be completely immersed in the urine. At this time, by pressing the pressing block 201, the trapezoidal block 204 on the pressing block 201 can squeeze the trapezoidal block 205, causing the trapezoidal block 205 to move axially. This can drive the piston rod 2012 to pull the rubber piston 2013, thereby drawing urine into the container through the suction nozzle 207 and the catheter 206. Furthermore, a piston rod 208 is fixed to the side of trapezoidal block 205 away from spring 2010. A rubber piston 2014 is fixedly connected to the end of piston rod 208 away from trapezoidal block 205. The surface of rubber piston 2014 is sleeved on the inner wall of piston cylinder 203. The surface of piston cylinder 203 is fixedly connected to the inner wall of housing 101. One end of piston cylinder 203 is fixedly connected to two sets of airbag rings 2015 through air guide pipe 209. The surfaces of both sets of airbag rings 2015 are fixedly connected to the inner wall of release cylinder 2011. Airbag rings 2015 are inflatable rubber airbags that can be used to seal the port of release cylinder 2011 when inflated. It should be noted that when trapezoidal block 205 is squeezed by trapezoidal block 204, piston rod 208 can drive rubber piston 2014 to move, thereby quickly filling the gas inside piston cylinder 203 into the two sets of airbag rings 2015 through air guide tube 209, causing airbag rings 2015 to expand and seal release cylinder 2011, ensuring that the entire path of catheter 206 is in a relatively sealed state when drawing urine. As trapezoidal block 204 continues to squeeze trapezoidal block 205, rubber piston 2014 continues to move. After moving a short distance, rubber piston 2014 will block the air outlet of piston cylinder 203, preventing piston cylinder 203 from emitting air and avoiding over-inflation that could cause airbag ring 2015 to over-expand and rupture. Furthermore, after sufficient urine has been collected, the housing 101 can be removed from the urine container. Then, the sleeve 102 is quickly placed over one end of the housing 101, blocking the suction nozzle 207. The housing 101 is then flipped over so that the test strip 103 is below the release cylinder 2011. At this point, the pressing block 201 is released. The elasticity of the spring 2010 causes the trapezoidal block 205 to slowly reset, thereby resetting the trapezoidal block 204 and the pressing block 2011. 1. The piston rod 208 also resets, driving the rubber piston 2014 to reset and extracting the gas inside the airbag ring 2015, causing the airbag ring 2015 to contract and opening the port of the release cylinder 2011. At this time, the piston rod 2012 also drives the rubber piston 1013 to reset. Since the suction nozzle 207 has been blocked by the sealing gasket of the sleeve 102, the urine will be discharged from the port positions of the two sets of release cylinders 2011, accurately released into the detection area and control area of the test strip 103.
[0019] The working principle of this utility model is as follows: The housing 101 serves as an overall frame, providing installation space for components such as the test strip 103 and the urine catheterization mechanism 200, while protecting the internal structure from external contamination. The sleeve 102 is snapped into the urine inlet of the housing 101. When not in use, the suction nozzle 207 is sealed by the internal sealing gasket to prevent components such as the urine catheter 206 from being contaminated by dust or impurities. When in use, it can be removed or loosened to expose the suction nozzle 207 for drawing urine. The test strip 103 is fixed to the inner wall of the housing 101, and its detection area and control area correspond to the outlet of the release tube 2011 to ensure that urine can flow accurately through the two areas to complete the HCG detection and validity verification. The user inserts the urine inlet end of the housing 101 into a container filled with urine, so that the suction nozzle 207 is completely immersed in the urine. Pressing the pressing block 201 causes it to slide down along the inner wall of the housing 101, which drives the bottom trapezoidal block 1 204 to move down simultaneously. The trapezoidal block 1 204 and the inclined surface of trapezoidal block 205 are pressed together, pushing the trapezoidal block 205 to move towards the piston cylinder 1 202. At this time, the spring 2010 is compressed. The trapezoidal block 205 pulls the rubber piston 1 2013 inside the piston cylinder 1 202 through the piston rod 2012, so that a negative pressure is formed inside the piston cylinder 1 202. The urine is drawn in through the suction nozzle 207 and the catheter 206 and temporarily stored in the catheter 206 and the release cylinder 2011. As trapezoidal block 205 moves, piston rod 208 on its other side pushes rubber piston 2014 inside piston cylinder 203, forcing gas in piston cylinder 203 into airbag ring 2015 through air guide tube 209. After airbag ring 2015 expands, it seals the outlet of release cylinder 2011 to prevent leakage when drawing urine, ensuring that a closed space is formed inside catheter 206 and release cylinder 2011 to prevent urine from contaminating the inside of shell 101. After collecting sufficient urine, the user removes the housing 101 from the container, reattaches the sleeve 102 to the urine inlet of the housing 101, seals the nozzle 207 with the sealing gasket to prevent urine backflow, and flips the housing 101 so that the test strip 103 is below the release tube 2011. The user releases the pressing block 201, the spring 2010 resets, pushing the trapezoidal block 205 to move in the opposite direction, the rubber piston 2013 resets, and the urine in the catheter 206 and release tube 2011 is ready to be released under pressure. The rubber piston 2014 resets, the airbag 2015 deflates and contracts, the outlet of the release tube 2011 opens, and the urine drips precisely onto the detection area and control area of the test strip 103. Finally, the detection area reacts with HCG in the urine to produce color, and the control area simultaneously develops color to verify the validity of the test. The user can read the results through the observation window.
