Description

Technical Field

[0001] The present invention relates to the field of urine testing, and in particular to a toilet with a urine testing device and a urine testing method. Background Art

[0002] Urinalysis is a routine medical test item suitable for health monitoring of the vast majority of people. Urine needs to be collected in a plastic cup and then tested with a test strip. This process not only requires adjusting posture during urination, but also requires attention to avoid contaminating the urine and causing splashing. The traditional urine collection process is already inconvenient for adults, and even more inconvenient or difficult for the elderly or young children. In the current urine collection method, it is necessary to consider that the landing point of urine from different people varies greatly, making it difficult to accurately control the contact of urine with the test paper. If the urine is collected before contacting the test paper, the urinal that controls the collection of urine will be contaminated. If a disposable membrane material is used as a collection urinal, it needs to be kept taut during the transmission process, otherwise it will be difficult to unwind and rewind. However, the membrane material in a taut state cannot collect urine, which causes many problems in its actual use. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem of inconvenience in sampling during the current urine test process and to propose a toilet with a urine test device and a urine test method.

[0004] To achieve the above-mentioned object, the present invention adopts the following technical solution: a toilet with a urine testing device includes a mounting frame and a buffer seat ring movably connected thereto, the buffer seat ring including a ring body and two elastic slides on which an unwinding assembly and a rewinding assembly are slidably mounted, and a support rod movably connected to the mounting frame for pressing and holding the elastic slides in displacement; The unwinding assembly and the winding assembly for conveying the urinary catheter film are symmetrically installed at the bottom of the ring body, and a driving assembly for unidirectionally transmitting the wound urinary catheter film is installed on one side of the winding assembly; One end of the buffer seat is equipped with a clamping seat for positioning the test paper at a specified position; Under the pressure of the ring and the support of the support rod, the two elastic slides carry the unwinding assembly and the rewinding assembly to move toward each other in an arc track, so that the top of the taut urinary catheter membrane remains unchanged, and the bottom is loose and hangs down to the test paper on the clamping seat.

[0005] As a further description of the above technical solution: the buffer seat ring also includes two arc-shaped sliding grooves symmetrically opened at the bottom of the ring body, the bottom of the ring body is fixed with a hook plate for limiting the sliding of the support rod therein, and the bottom of the ring body is integrally formed with a support seat that cooperates with the support on the mounting frame.

[0006] As a further description of the above technical solution: the elastic slide includes a frame body for installing the corresponding unwinding component or the rewinding component, and a slider that slides in the arc-shaped slide groove is provided on the top of the frame body, and a spring is fixed on one side of the slider, and the other end of the spring is fixed to the inner wall of the arc-shaped slide groove, and the side wall of the frame body is provided with an inclined guide groove that fits the support rod.

[0007] As a further description of the above technical solution: the unwinding assembly includes an unwinding frame fixed on a corresponding frame, and a first guide roller and a feed roller are rotatably installed at both ends of the unwinding frame. A first one-way ratchet for controlling the one-way rotation of the feed roller and the unwinding frame is provided between the feed roller and the unwinding frame, and a circle of triangular cutters for evenly forming holes at the bottom of the urinary catheter membrane is provided on the side wall of the first guide roller.

[0008] As a further description of the above technical solution: the winding assembly includes a winding frame fixed on the corresponding frame body, and the two ends of the winding frame are rotatably connected to the second guide roller and the winding roller, and the winding roller and the winding frame are unidirectionally transmitted through a second one-way ratchet.

[0009] As a further description of the above technical solution: the driving assembly includes a driving gear rotatably connected to the middle section of the winding frame, the driving gear is engaged with a driven gear fixed to one end of the winding roller, the surface of the driving gear is provided with a swing arm that rotates unidirectionally through a third one-way ratchet, and a counterweight block is installed at the bottom end of the swing arm.

[0010] As a further description of the above technical solution: the wheel bodies of the first one-way ratchet and the second one-way ratchet are fixed with ratchet teeth that rotate in the same direction, the ratchet teeth of the third one-way ratchet are fixed with the driving gear and the wheel body is fixed to the swing arm on one side of the gear.

[0011] As a further description of the above technical solution: the sliding angle of the frame body in the arc-shaped slide groove is a deflected sliding around the end of the first guide roller or the second guide roller as the center of the circle.

[0012] As a further description of the above technical solution: the clamping seat includes a pin seat fixed at the bottom of the ring body, and a positioning arm is rotatably provided on the inner wall of the pin seat, the positioning arm is provided with a clip for clamping the test paper, the end of the positioning arm is provided with a push rod for finger pressing, and the inner wall of the pin seat is provided with a limiting boss for limiting the deflection angle of the positioning arm.

[0013] A urine test method comprising the following steps: S1. Clamp the test paper at the bottom of the clamping seat or pass it through the middle hole of the first guide roller on the catheterization membrane, and then lower the seat ring in the upright folded state; S2, sitting on the buffer seat ring, so that the two elastic carriages move in an arc trajectory with the unwinding assembly and the rewinding assembly under the pressure of the ring body and the support of the support rod. At this time, the top of the urinary catheter membrane remains tense, and the bottom loses tension and droops; S3. When using: S3.1 If the test strip is located at the bottom of the holder: The bottom of the catheter membrane hangs down above the test paper and forms a drainage pattern, collecting urine and contacting the exposed part of the test paper. S3.2 If the test strip is located in the middle of the urethral catheterization membrane: The test paper penetrates the hole of the catheter membrane, and the area it passes through is exposed. Under the gravity of the test paper, the loosened area at the bottom of the catheter membrane is pressed and collapsed to form a drainage shape, which gathers urine on the test paper for full contact.

[0014] S4. When the test is completed: S4.1 If the test strip is located at the bottom of the holder: Rotate the clamp to remove the test paper clamped at a fixed point, and then remove the unexposed area of the test paper by hand; S4.1 If the test strip is located in the middle of the urethral catheterization membrane: Pinch the unexposed area of the test paper at the bottom of the tilted catheter membrane and pull it out of the perforation of the catheter membrane.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: When the present invention is in use, through the one-way transmission driving assembly, during the folding process, the counterweight block deflects with the ring body, the center of gravity changes, and the swing arm drives the driving gear to rotate, and the driving gear can drive the driven gear to rotate multiple times to realize the winding roller to replace the urinary catheter film. When the person uses it later, the ring body is reset. At this time, the counterweight block drives the swing arm to move back, and the third one-way ratchet does not drive the driving gear to rotate at this time. In this way, there is no need for personnel to rewind the film, and the rewinding and replacement of the urinary catheter film can be realized during the retraction and release process after each use, avoiding the problem of contamination affecting the test results due to the subsequent use of the film not being rewound. At the same time, when in use, as a person sits or stands on the circle body, the circle body and the support rod work together to deflect and displace the elastic slide in the arc-shaped slide groove under the pressure of the human body, and the displacement of the elastic slide moves toward each other along the first guide roller and the second guide roller of the unwinding assembly and the rewinding assembly as the center of the circle, forming a state in which the top of the catheterization membrane remains taut and the bottom is relaxed, so that the bottom is relaxed and hangs down above the test paper. This method can keep the catheterization membrane taut when no one is sitting on the circle body, which is convenient for transmission. At the same time, it can switch to the catheterization state when a person is in use through the change of shape, which is convenient for collecting urine to the position of the test paper. It is simple and convenient to use and has a reliable and stable structure. At the same time, when people are using it, the counterweight, unwinding assembly and rewinding assembly are installed on one side of the ring body, which makes it heavy. There will be a large impact force when it is put down from the upright folded state. If it is like this for a long time, it is very easy to cause damage to the ring body. In this solution, two support rods are designed to be forked in an eight-shaped pattern and supported on the corresponding elastic slides on both sides of the ring body. When the ring body falls, under the guidance of the hook plate, the support rod deflects and finally inserts into the oblique guide groove on the inner wall of the elastic slide to make contact, so that the impact force of its fall is used by the oblique guide groove to cause the frame to slide slightly in the arc slide groove and press the spring. The elastic force of the spring reacts to reset it, and cooperates with the metal elasticity of the support rod to play a buffering role, avoiding the ring body directly hitting the mounting frame and causing damage; When in use, the feeding roller, the winding roller, the first guide roller and the second guide roller all have open ends, so the urinary catheter membrane can be replaced simply and quickly, and is easy to use.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1 - Figure 18 As shown, the present invention provides: a toilet with a urine testing device, including a mounting frame 10 and a buffer seat ring 20 movably connected thereto, the buffer seat ring 20 including a ring body 21 and two elastic slides 23 on which an unwinding assembly 30 and a rewinding assembly 40 are slidably mounted, and a support rod 26 movably connected to the mounting frame 10 for pressing and displacing the elastic slides 23; The bottom of the ring body 21 is symmetrically mounted with an unwinding assembly 30 and a rewinding assembly 40 for conveying the urinary catheter film 70. A drive assembly 50 for unidirectionally driving and rewinding the urinary catheter film 70 is mounted on one side of the rewinding assembly 40. Through the coordinated action of the counterweight 55, the swing arm 54, and the third one-way ratchet 53, the device can automatically drive the driving gear 51 and the driven gear 52 to complete multiple turns of rewinding and replacement of the urinary catheter film 70 by gravity during the folding process, so that the film surface can be replaced without manual intervention after each use, eliminating the risk of contamination of the test paper due to failure to manually rewind. One end of the buffer seat ring 20 is equipped with a clamping seat 60 for positioning the test paper at a specified position; Under the pressure of the ring body 21 and the support of the struts 26, the two elastic slides 23 carry the unwinding assembly 30 and the rewinding assembly 40 in an arc-shaped displacement toward each other, keeping the top of the urinary catheter membrane 70 taut while the bottom relaxes and droops onto the test strip on the clamping seat 60. During use, the coordinated design of the annular chute, the inclined guide groove 233, and the spring 234 allows the elastic slides 23 to move downward along the arc-shaped trajectory after the ring body 21 bears the pressure of the human body, keeping the top of the urinary catheter membrane 70 continuously taut while the bottom naturally relaxes and droops, achieving an optimal urine guiding state and ensuring that urine can be stably collected on the test strip. At the same time, the two figure-eight struts 26, the hook plate 25, and the spring 234 act as a buffer, effectively absorbing the impact force when the seat ring is lowered and folded back, preventing the seat ring from directly impacting the mounting frame 10 and causing damage.

[0020] This solution addresses the issues of existing toilet-attached urine testing devices during use and storage, such as forgetting to manually rewind the membrane 70, the inability to automatically switch tension on the catheter membrane 70, and the seat being easily damaged by impact from falling. This solution addresses the problems of urine not being accurately collected on the test strip due to the membrane 70 not being relaxed in time, the cumbersome process of securing and removing the test strip, which affects test efficiency, and the excessive impact force that damages the cushioning seat 20 structure when the device is folded and lowered. This solution features automatic membrane retraction and rapid switching to the catheterization state of the membrane 70 after transport, simple test strip replacement, and a durable seat structure, providing greater convenience, reliability, and longevity for urine testing.

[0021] Specifically, such as Figure 4 and Figure 5 As shown, the buffer seat ring 20 also includes two arc-shaped sliding grooves 22 symmetrically opened at the bottom of the ring body 21, and a hook plate 25 is fixed at the bottom of the ring body 21 for limiting the sliding of the support rod 26 therein, and a support seat 24 is integrally formed at the bottom of the ring body 21 to cooperate with the support on the mounting frame 10.

[0022] By setting the buffer seat ring 20, a hook plate 25 is fixed on the ring body 21 of the buffer seat ring 20, and the hook plate 25 can limit the support rod 26. The two support rods 26 are inclined in an eight-shaped shape, and there is a certain angle compared to the angle change of the ring body 21. When the ring body 21 is stored, it deflects around the active point of the mounting frame 10. At this time, the support rod 26 also begins to deflect under the limitation of the hook plate 25, but the support rod 26 is deflected in an inclined shape, which will slide in the hook plate 25. At the same time, when the support rod 26 is active, it can slide into and out of the inclined guide groove 233. As the frame 231 moves downward, the support rod 26 moves downward at the same time and has a horizontal displacement until it moves horizontally to the position of the inclined guide groove 233 and then inserts into the inclined guide groove 233 (there is a distance difference between the ring body 21 and the support rod 26 at the active point of the mounting frame 10, which forms a state where the support rod 26 is inserted into the inclined guide groove 233). The arc-shaped sliding groove 22 can meet the requirements of the sliding block 232 on the frame 231 to cooperate with the limited sliding, and its curvature can lead the frame 231 to deflect at a certain angle.

[0023] The support rod 26 can also provide a certain supporting effect on the ring body 21 based on the mounting frame 10 .

[0024] Specifically, such as Figure 8 As shown, the elastic slide 23 includes a frame body 231 for installing the corresponding unwinding component 30 or the winding component 40, and a slider 232 is provided on the top of the frame body 231 for sliding in the arc-shaped slide groove 22, and a spring 234 is fixed on one side of the slider 232, and the other end of the spring 234 is fixed to the inner wall of the arc-shaped slide groove 22, and the side wall of the frame body 231 is provided with an inclined guide groove 233 that fits the support rod 26.

[0025] By setting up the elastic slide 23, its frame 231 not only bears the installation support of the unwinding component 30 or the rewinding component 40, but its top slider 232 is just embedded in the arc-shaped slide 22 at the bottom of the ring body 21, so that when it bears the weight of the human body or the counterweight position, the frame 231 can move smoothly along the predetermined curve; one side of the slider 232 is pre-installed with a spring 234, and the other end is fixed to the inner wall of the slide, so that the frame 231 obtains moderate damping during the downward pressure process and quickly returns to its original position after the external force disappears. This spring 234 buffer design not only ensures the smoothness and stability of the tension switching of the catheter membrane 70, but also prevents the mechanism from repeatedly moving up and down. The support rod 26 is guided and slid along the inclined guide groove 233 when the frame 231 moves downward, thereby forming a force conversion and displacement guide, effectively controlling the movement angle and speed of the frame 231, so that the urinary catheterization membrane 70 is always kept in a taut state at the top and naturally hangs down at the bottom, thereby realizing accurate urine guidance; the overall structure cooperates with the slider 232, the spring 234 and the inclined guide groove 233, which not only makes the unwinding and rewinding motion trajectory controllable and slow, but also has the functions of automatic reset and impact absorption, thereby greatly improving the reliability and comfort of use of the device.

[0026] Specifically, such as Figure 8 As shown, the unwinding assembly 30 includes an unwinding frame 31 fixed on the corresponding frame 231, and a first guide roller 32 and a feeding roller 33 are rotatably installed at both ends of the unwinding frame 31. A first one-way ratchet 34 for controlling the unidirectional rotation of the feeding roller 33 is provided between the unwinding frame 31, and the side wall of the first guide roller 32 is provided with a circle of triangular cutters for evenly forming holes at the bottom of the urinary catheter membrane 70.

[0027] The unwinding frame 31 in the unwinding assembly 30 is tightly combined with the frame body 231 to form an integral support. The first guide roller 32 and the feed roller 33 are axially connected at both ends to enable the catheter film 70 to be smoothly transported along a predetermined trajectory during the unwinding process. The first one-way ratchet 34 embedded between the feed roller 33 and the unwinding frame 31 remains free to rotate when the film is unwound outward, and is automatically locked when it is retracted, ensuring that the catheter film 70 only slides in the unwinding direction and does not relax in the reverse direction due to external forces, thereby always maintaining the tension of the film. At the same time, a circle of triangular cutters arranged around the side wall of the first guide roller 32 precisely perforates the bottom of the catheter film 70. The tip of the cutter cuts small holes along the film surface at uniform intervals. When the test strip is inserted into or passes through these holes, the film and the test strip can be tightly attached and the fluid can be smoothly guided. The cutter structure itself resets itself when the catheter film 70 passes by without hindering continuous unwinding. This design enables the unwinding assembly 30 to not only automatically control the film falling speed and tension, but also provide stable hole position support during the contact process between the film body and the test paper.

[0028] Specifically, such as Figure 7As shown, the winding assembly 40 includes a winding frame 41 fixed on the corresponding frame body 231, and the two ends of the winding frame 41 are rotatably connected to the second guide roller 43 and the winding roller 42, and the winding roller 42 and the winding frame 41 are unidirectionally transmitted through the second one-way ratchet 44.

[0029] The core of the winding assembly 40 lies in the close combination of the winding frame 41 and the frame body 231, making the entire mechanism a rigid whole. The second guide roller 43 and the winding roller 42 are connected to the two ends through bearings respectively, to ensure the smooth guidance of the film during the winding process; after the second one-way ratchet 44 is introduced between the winding roller 42 and the winding frame 41, the winding roller 42 can only rotate freely in the direction of ensuring the recovery of the film. When the user sits down again to cause the frame body 231 to reset or the counterweight block 55 swings the arm 54 to drive the active gear 5 When the meshing driven gear 52 drives the winding roller 42 to rotate, the second one-way ratchet 44 performs a locking function to prevent any reverse relaxation, so that the urinary catheter film 70 can be firmly wound into the winding roller 42 with multiple turns. This one-way transmission mechanism not only ensures that the urinary catheter film 70 can be completely wound up and replaced with a new film segment after each use, but also maintains the film tension during use through the ratchet self-locking function, avoiding film relaxation caused by external force swinging or the seat ring being lifted, thus realizing the dual functions of automatic winding and tension maintenance.

[0030] Specifically, such as Figure 7 As shown, the driving assembly 50 includes a driving gear 51 rotatably connected to the middle section of the winding frame 41, the driving gear 51 meshes with a driven gear 52 fixed to one end of the winding roller 42, and a swing arm 54 is unidirectionally rotated on the surface of the driving gear 51 through a third one-way ratchet 53, and a counterweight 55 is installed at the bottom end of the swing arm 54. Specifically, as shown in FIG. Figure 6 and Figure 18 As shown, the first one-way ratchet 34 and the second one-way ratchet 44 have their wheel bodies fixed with ratchet teeth that rotate in the same direction, and the ratchet teeth of the third one-way ratchet 53 are fixed with the driving gear 51 and the wheel body rotates and is fixed to the swing arm 54 on one side of the gear.

[0031] The driving assembly 50 is firmly mounted on the middle section of the winding frame 41 by rotating the driving gear 51 so that it meshes with the driven gear 52 fixed at the end of the winding roller 42, ensuring that the driven gear 52 rotates with the driving gear 51 and stably drives the winding roller 42 to rewind the urinary catheter film 70; a third one-way ratchet 53 is embedded on the surface of the driving gear 51, and its ratchet teeth are fixed to the driving gear 51 as a whole, while the wheel body of the third one-way ratchet 53 rotates freely through the bearing and is fixed to the swing arm 54; after the counterweight 55 is added to the bottom end of the swing arm 54, when the seat ring is folded or lifted, the gravity of the counterweight 55 drives the swing arm 54 to swing, and the third one-way ratchet 53 is fixed to the swing arm 54. The wheel body of the one-way ratchet 53 drives the driving gear 51 to rotate continuously for multiple turns in a one-way locking manner as the swing arm 54 moves, thereby realizing the automatic recovery of the catheter film 70 by the winding roller 42; when the seat ring returns to the horizontal use state, the counterweight block 55 drives the ratchet wheel body to deflect in the opposite direction along the return direction of the swing arm 54, but because the third one-way ratchet 53 only allows the ratchet teeth to engage along the predetermined direction, the driving gear 51 can remain stationary and is not affected by the reset of the swing arm 54, completing the automatic film replacement without reverse loosening. The overall structure not only realizes the automatic multi-turn winding of the catheter film 70, but also stably maintains the film tension and position by virtue of the ratchet self-locking function.

[0032] Specifically, such as Figure 16 As shown, the sliding angle of the frame 231 in the arc-shaped sliding groove 22 is a deflected sliding around the end of the first guide roller 32 or the second guide roller 43 as the center of the circle.

[0033] The moving trajectory of the frame 231 in the arc-shaped chute 22 takes the end of one side of the first guide roller 32 or the second guide roller 43 as the geometric center, and the other end of the guide roller is driven to rotate by eccentric arc sliding, ensuring that the catheterization membrane 70 always maintains tension balance with the end of one side of the guide roller as the fulcrum during the downward movement of the frame 231, and there will be no lateral displacement of the guide roller or distortion of the membrane surface due to offset; at the same time, this center-of-center deflection sliding provides a constant curvature arc for the relative displacement of the membrane and the frame 231, so that the frame 231 can move downward smoothly when subjected to human body pressure, and accurately return along the opposite arc path after the external force disappears, avoiding jamming or impact caused by sudden trajectory changes in traditional linear guides; by sliding in an arc around the end of the guide roller, not only is the top membrane surface always kept in a high tension state concentric with the guide roller, but the bottom also automatically obtains sufficient relaxation margin at the same offset angle, thereby realizing the change of urine guidance angle and improving the efficiency and accuracy of catheterization during use.

[0034] Specifically, such as Figure 9As shown, the clamping seat 60 includes a pin seat 61 fixed to the bottom of the ring body 21, and a positioning arm 63 is rotatably provided on the inner wall of the pin seat 61. The positioning arm 63 is provided with a clip 65 for clamping the test paper, and the end of the positioning arm 63 is provided with a push rod 64 for finger pressing. The inner wall of the pin seat 61 is provided with a limiting boss 62 for limiting the deflection angle of the positioning arm 63.

[0035] The clamping seat 60 fixes the pin seat 61 to the bottom of the buffer seat ring 20. The inner wall of the pin seat 61 is provided with a precisely matched rotating bearing surface. The positioning arm 63 can rotate freely around this rotating axis without any shaking clearance. The upper end of the positioning arm 63 can accurately position the test paper under the urinary catheter membrane 70 by rotating; the metal clip 65 installed at the lower end of the positioning arm 63 firmly clamps the edge of the test paper in an elastic clamping manner, and uses the friction between the clip 65 and the test paper to prevent it from slipping during the seating or removal process; at the same time, the limiting boss 62 on the inner wall of the pin seat 61 engages with the end of the positioning arm 63, limiting the maximum deflection angle of the arm body, which not only ensures that the test paper is in the same direction when it is moved out of the ring body 21, but also avoids excessive rotation causing interference between the test paper and the urinary catheter membrane 70 or the seat ring structure, thereby realizing rapid installation, stable retention and easy replacement of the test paper.

[0036] Urine test method: S1. Clamp the test paper at the bottom of the clamping seat 60 or pass it through the middle hole of the first guide roller 32 on the urinary catheterization membrane 70, and then lower the seat ring in the upright folded state; S2. Sit on the buffer seat ring 20, so that the two elastic carriages 23 move toward each other in an arc trajectory with the unwinding assembly 30 and the rewinding assembly 40 under the pressure of the ring body 21 and the support of the support rod 26. At this time, the top of the urinary catheter membrane 70 remains tense, and the bottom loses tension and droops; S3. When using: S3.1. If the test paper is located at the bottom of the holder 60: The bottom of the urinary catheter membrane 70 hangs down above the test paper and forms a drainage shape, collecting urine and contacting the exposed part of the test paper. S3.2. If the test strip is located at the middle hole of the urinary catheterization membrane 70: The test paper penetrates the hole of the catheter membrane 70, and the area it passes through is exposed. Under the weight of the test paper, the loose area at the bottom of the catheter membrane 70 is pressed and collapsed to form a drainage shape, which collects urine on the test paper for full contact.

[0037] S4. When the test is completed: S4.1. If the test paper is located at the bottom of the holder 60: Rotate the clamping seat 60 to remove the test paper clamped at a fixed point, and then remove the unexposed area of the test paper by hand; S4.1. If the test strip is located at the middle hole of the urinary catheterization membrane 70: Pinch the unexposed area of the test paper at the bottom of the inclined catheterization membrane 70 and pull it out of the hole in the catheterization membrane 70.

[0038] When the present invention is in use, as the user sits or stands on the ring body 21, the ring body 21 is subjected to pressure and the frame 231 of the elastic slide 23 is moved downward to a horizontal state (after the buffer seat 20 is folded and lowered, the elastic slide 23 is supported on the surface of the support rod 26 by the action of the spring 234 through the inclined guide groove 233 on the surface, so that the ring body 21 is tilted at an angle of about five degrees). As the frame 231 is pressed downward and the inclined guide groove 233 on its surface cooperates and slides with the support rod 26, the frame 231 is displaced and slides in the arc-shaped slide groove 22, pressing the spring 234 to contract; As the frame 231 moves, the Figure 16 As shown, the frame 231 slides in the arc-shaped chute 22, and deflects with one end of the first guide roller 32 or the second guide roller 43, and the deflection takes the other end of the first guide roller 32 or the second guide roller 43 as the center of the circle, so that the top of the urinary catheter film 70 kept in a taut state by the first guide roller 32 and the second guide roller 43 remains in a taut state, but the bottom of the urinary catheter film 70 in an inclined state deflects with one end of the first guide roller 32 and the second guide roller 43, and the bottom of the urinary catheter film 70 in an inclined state deflects with the first guide roller 32 and the second guide roller 43. Figure 14 and attached Figure 15 As shown, the urinary catheter membrane 70 becomes loose and hangs down from the tightened state, so that it forms a urine guiding state with a tightened top and a relaxed bottom.

[0039] During use, the test paper can be installed in two ways. One is to fix it on the clamping seat 60 and install it by rotating the bottom of the positioning arm 63 on the pin seat 61. The bottom of the positioning arm 63 has multiple clips 65 to clamp the test paper. By rotating the positioning arm 63, it can be rotated ninety degrees to remove the test paper from the bottom of the ring body 21, making it easy to replace the test paper. Second, combined with the Figure 17 As shown, the surface of the first guide roller 32 pokes a hole smaller than the test paper on the urinary catheter membrane 70. When necessary, the test paper can be inserted into the hole in the middle of the urinary catheter membrane 70 (as shown in FIG. Figure 8 As shown, the side wall of the second guide roller 43 is provided with a circle of triangular cutters that evenly form holes on the bottom of the urinary catheterization film 70. The urinary catheterization film 70 is stretched to fit tightly against the test paper and clamp it. At this time, the gravity of the test paper further cooperates with the relaxation of the bottom of the urinary catheterization film 70 to press it down, maintaining a better catheterization and contact detection effect. Combined with attachment Figure 18As shown, the figure shows the rotation state from a rear view (the rotation direction is described based on the direction of this view in this paragraph), and it should be noted that the ratchet used in this device only needs to be able to achieve unidirectional rotation. The actual structure adopted is to achieve unidirectional engagement between the internal ratchet and the external wheel body, wherein the feed roller 33 rotates unidirectionally in the clockwise direction R2 of the figure to maintain unidirectional discharging, and the ratchet teeth of the first one-way ratchet 34 rotate with the feed roller 33, and the wheel body is fixed on the unwinding frame 31; correspondingly, the winding roller 42 is basically the same as the feed roller 33, and is also fixed with the ratchet teeth of the second one-way ratchet 44, so that when it rotates, it cooperates with the unidirectional rotation of the wheel body fixed on the winding frame 41, Unlike the feeding roller 33, the ratchet end of the second one-way ratchet 44 also has a one-way transmission effect on the driven gear 52. The driven gear 52 is fixed to one end of the winding roller 42 and rotates coaxially to achieve one-way cooperation; correspondingly, R3 is the rotation direction of the driving gear 51. Because the driving gear 51 is meshed with the driven gear 52, its transmission direction is fixed to the counterclockwise direction of R3, and the driving gear 51 is fixed to the ratchet teeth of the third one-way ratchet 53, and the wheel body of the third one-way ratchet 53 is rotatably connected to one side of the driving gear 51 and fixed to the swing arm 54, so that the rotation direction of the swing arm 54 is Y1 or the opposite direction of Y1. It can be foreseen that this rotation is combined with the following. See the attached Figure 2 When the ring body 21 is stored vertically, the swing arm 54 and the counterweight 55 drive the wheel body of the third one-way ratchet 53 to rotate in the opposite direction to the Y1 direction, so that the wheel body engages with the ratchet teeth to rotate the driving gear 51, and the driving gear 51 drives the winding roller 42 to rotate multiple circles through the driven gear 52. When the ring body 21 is placed horizontally for use, the wheel body of the third one-way ratchet 53 deflects along the Y1 direction with the swing arm 54, so that the driving gear 51 is not affected, and the counterweight 55 and the swing arm 54 are reset. This method realizes the automatic winding and replacement of the urinary catheter membrane 70 during the retraction and extension process of the buffer seat ring 20, avoiding the situation where the user fails to replace the urinary catheter membrane 70 and urine contamination occurs.

[0040] In summary, this solution combines gravity drive with the transmission of the third one-way ratchet 53. The counterweight 55, the swing arm 54, and the third one-way ratchet 53 automatically complete the multiple-turn winding and replacement of the urinary catheter membrane 70 during the folding and resetting of the seat ring, fundamentally eliminating the tediousness and risk of omissions in manual winding. The curved chute 22, the oblique guide groove 233, the spring 234, and the figure-eight support rod 26 cooperate to allow the elastic slide 23 to move down along a predetermined arc when the user sits down, causing only the bottom of the urinary catheterization membrane 70 to relax and sag while the top remains taut, automatically switching between the alternate transmission state and the urinary catheterization state during the detection process, achieving precise urine collection. Furthermore, the hook plate 25 guides the support rod 26 into the oblique guide groove 233 to create a buffering effect, effectively absorbing impact energy when the seat is folded down and raised back up, significantly improving the durability and reliability of the overall structure. The test strips have a dual installation and positioning method, which makes the replacement and removal of the test strips more convenient, and patients can use them according to their needs.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
