Description

Technical Field

[0001] The invention relates to the technical field of urinary catheter placement devices, in particular to a urinary catheter placement device which is convenient for collecting urine. Background Art

[0002] A urinary catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride. It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine. It is mainly used in indwelling catheterization. For example, in bladder management after cervical cancer surgery, a urinary catheter is usually required to assist the patient in urination and collect urine specimens and other postoperative management tasks. In particular, collecting urine through a urinary catheter is an important means of detecting postoperative recovery status data.

[0003] When collecting urine samples with the existing urinary catheter, in order to achieve the purpose of aseptic operation, it is necessary to disinfect the external pipe of the urinary catheter twice, then pierce the urinary catheter with a needle tip and extract urine for sampling, which greatly increases the workload of medical staff and makes the collection of urine samples with the urinary catheter very cumbersome, not convenient and fast enough. In addition, since urine samples need to be collected multiple times to observe the patient's recovery status, multiple pinholes will be left on the urinary catheter, which not only damages the urinary catheter, but also easily causes the inside of the urinary catheter to be contaminated by bacteria through the pinholes, resulting in urinary tract infection, affecting the safety of the urine sample collection work with the urinary catheter.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing urinary catheter, and even if it can be solved, it needs to be solved with the cooperation of external tools, which cannot achieve the desired effect.

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 creative work are within the scope of protection of the present invention.

[0036] The collection mechanism 2 includes a urine collection unit 21 . The urine collection unit 21 is disposed outside the urinary catheter 11 . The urine collection unit 21 is used to sample and collect urine in the urinary catheter 11 .

[0037] As a further limitation of the collection mechanism 2 of the present invention, the urine collection unit 21 includes a connecting tube 2101, which is arranged on the outside of the urinary catheter 11, and a connecting tube 2102 is clamped inside the connecting tube 2101, one end of the connecting tube 2102 penetrates into the inside of the urinary catheter 11, and two first rubber gaskets 2103 are fixedly connected to the inner wall of the connecting tube 2101, and a second rubber gasket 2104 is fixedly connected to the inner wall of the connecting tube 2102. A fixing ring 2105 is fixedly connected to the inner wall of the connecting tube 2101, and the fixing ring 2105 is located on the left side of the first rubber gasket 2103. A compression spring 2106 is fixedly connected to the left side of the fixing ring 2105, and the other end of the compression spring 2106 is fixedly connected to a limiting disk 2107. An opening is provided on the left side of the limiting disk 2107, a sliding groove 2108 is provided on the upper part of the outer surface of the connecting tube 2101, and a connecting frame 2109 is slidably connected inside the sliding groove 2108, and the bottom surface of the connecting frame 2109 is fixedly connected to the outer surface of the limiting disk 2107, and a sampling syringe 2110 is provided on the left side of the connecting tube 2101. The needle of the sampling syringe 2110 passes through the limiting disk 2107, the fixing ring 2105 and the two first rubber gaskets 2103 in sequence and extends to the left side of the second rubber gasket 2104, and a fixing frame 2111 is fixedly connected to the upper part of the outer surface of the connecting tube 2101, and a rotating rod 2112 is rotatably connected to the inner part of the fixing frame 2111, and a rotating cylinder 2113 is fixedly connected to the outer surface of the rotating rod 2112, and the rotating cylinder 2113 is fixedly connected to the rotating cylinder 21 13 is rotatably connected to the inside of the fixed frame 2111, the outer surface of the rotating cylinder 2113 is fixedly connected to a plurality of color cards 2114, the outer surface of the rotating rod 2112 is fixedly connected to two ratchet gears 2115, the front and back sides of the connecting frame 2109 are fixedly connected to connecting plates 2116, the two connecting plates 2116 are both located inside the fixed frame 2111, the upper surfaces of the two connecting plates 2116 are fixedly connected to two connecting springs 2117, the tops of the two connecting plates 2116 are each provided with a ratchet plate 2118, each connecting spring 2117 is fixedly connected to the bottom surface of the ratchet plate 2118, the upper surfaces of the two ratchet plates 2118 are meshed with the outer surface of the ratchet gear 2115, and the interior of each connecting spring 2117 is provided with There are telescopic rods 2124, and the telescopic ends of each telescopic rod 2124 are fixedly connected to the bottom surface of the ratchet plate 2118, and the bottom ends of each telescopic rod 2124 are fixedly connected to the upper surface of the connecting plate 2116. By setting the urine collection unit 21, the two first rubber gaskets 2103 are used in conjunction with the connecting tube 2101 to effectively isolate external bacteria from entering the interior of the urinary catheter 11. At the same time, the sampling syringe 2110 can be used to conveniently sample urine in the urinary catheter 11 without leaving pinholes on the urinary catheter 11, thereby reducing damage to the urinary catheter 11. After the urine collection work is completed, the urinary catheter 11 will not be contaminated by bacteria due to too many pinholes, causing urinary tract infection in the patient, thereby effectively increasing the safety of the urine sample collection work of the urinary catheter 11.

[0038] The outer surface of the connecting tube 2102 is fixedly connected with a limiting ring 2119, and the left side of the limiting ring 2119 contacts the right end of the connecting tube 2101. The limiting ring 2119 can limit the position of the connecting tube 2101 on the connecting tube 2102, preventing the connecting tube 2101 from excessively moving to the left and affecting the sealing performance, thereby improving the matching accuracy of the connecting tube 2102 and the connecting tube 2101;

[0039] Two clamping rings 2120 are fixedly connected to the outer surface of the connecting tube 2102. The two clamping rings 2120 are clamped in the interior of the connecting tube 2101. The clamping rings 2120 can increase the contact area between the connecting tube 2102 and the connecting tube 2101, thereby increasing the sealing of the gap between the connecting tube 2102 and the connecting tube 2101, making it difficult for external bacteria and impurities to enter the interior of the connecting tube 2101 through the gap between the connecting tube 2102 and the connecting tube 2101.

[0040] The inner wall of the fixing frame 2111 is fixedly connected with two symmetrical sliding rods 2121, and the inner walls of the two connecting plates 2116 are respectively slidably connected with the outer surfaces of the sliding rods 2121. The sliding rods 2121 can increase the stability of the connecting plates 2116 when sliding left and right, so that the connecting plates 2116 are not prone to excessive swinging, thereby increasing the reliability of the connecting plates 2116.

[0041] Two rubber blocks 2122 are sleeved on the outer surface of the rotating rod 2112, and the side surfaces of the two rubber blocks 2122 that are away from each other are fixedly connected to the inner wall of the fixing frame 2111. A plurality of cylindrical bars 2123 are fixedly connected to the outer surface of the rotating rod 2112, and the outer surfaces of the plurality of cylindrical bars 2123 are in contact with the inner wall of the rubber blocks 2122. Through the contact and cooperation between the rubber blocks 2122 and the cylindrical bars 2123, movement resistance can be provided for the rotation of the rotating rod 2112, so that the rotating rod 2112 is not easily rotated due to vibration and shaking, thereby improving the stability of the rotating rod 2112 after rotation.

[0042] The specific implementation of this embodiment is as follows: when it is necessary to collect a patient's urine specimen through the urinary catheter 11, it is only necessary to insert the needle of the sampling syringe 2110 into the connecting tube 2101 until the needle of the sampling syringe 2110 successively pierces the two first rubber gaskets 2103 and the second rubber gaskets 2104 and extends into the connecting tube 2102. At this time, it is only necessary to pull the internal pull rod and piston of the sampling syringe 2110 to suck the urine in the urinary catheter 11 through the connecting tube 2102 into the sampling syringe 2110 to complete the urine specimen collection work. At the same time, by utilizing the elastic force of the first rubber gasket 2103 and the second rubber gasket 2104 themselves, when the sampling syringe 2110 withdraws from the connecting tube 2101, the needle of the sampling syringe 2110 remaining in the first rubber gasket can be automatically sealed. The pinholes on the gasket 2103 and the second rubber gasket 2104 can effectively isolate external bacteria from entering the interior of the urinary catheter 11. At the same time, the sampling syringe 2110 can be used to conveniently collect urine samples from the interior of the urinary catheter 11 without leaving pinholes on the urinary catheter 11, thereby reducing damage to the urinary catheter 11 and preventing the urinary tract infection of the patient due to excessive bacterial contamination of the pinholes after the urine collection work is completed. This effectively increases the safety of the urine sample collection work of the urinary catheter 11. In addition, when the sampling syringe 2110 is inserted into the interior of the connecting tube 2101, the needle tube of the sampling syringe 2110 will push the limiting plate 2107 to move to the right and force the compression spring 2106 to be compressed under the limit of the fixing ring 2105. At this time, the limiting The disk 2107 will drive the connecting frame 2109 to slide to the right inside the sliding groove 2108, so that the connecting plate 2116 can drive the ratchet plate 2118 to move to the right with the assistance of the sliding rod 2121, and the inclined ratchet on the ratchet plate 2118 and the bending limit of the connecting spring 2117 by the telescopic rod 2124 can drive the ratchet gear 2115 to break through the friction between the rubber block 2122 and the cylindrical bar 2123 to rotate, so that the rotating rod 2112 drives the rotating cylinder 2113 to rotate a certain distance. At this time, the color card 2114 exposed to the outside of the fixed frame 2111 will also switch with the rotation of the rotating cylinder 2113, and then the color cards 2114 of different colors can be used to record the number of times the connecting cylinder 2101 is used. When the specified number of times is reached, the color card 2114 will display the corresponding color, which means that the connecting tube 2101 has been used many times and the degree of bacterial contamination is high. It is only necessary to use the friction between the limiting ring 2119 and the connecting tube 2101 to manually remove the connecting tube 2101 from the connecting tube 2102, disinfect the connecting tube 2102 and the second rubber gasket 2104, and then install a new connecting tube 2101. When the sampling syringe 2110 is pulled out from the inside of the connecting tube 2101 after urine collection is completed, the compression spring 2106 will push the limiting plate 2107 to move to the left, and then the connecting frame 2109 cooperates with the connecting plate 2116 to drive the ratchet plate 2118 to move to the left. At this time, the inclined ratchet on the ratchet plate 2118 and the ratchet gear 2115 is used.The elastic force of the connecting spring 2117 and the friction between the rubber block 2122 and the cylindrical bar 2123 limit the rotation rod 2112, which will cause the ratchet plate 2118 to disengage from the ratchet gear 2115, so that the ratchet plate 2118 cannot drive the ratchet gear 2115 to rotate, and the rotation rod 2112 can only rotate clockwise, ensuring the switching stability and accuracy of the color card 2114.

[0043] Example 2: Please refer to Figure 5 and Figure 6 The present invention provides a technical solution: a urinary catheter device for convenient urine collection. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The collection mechanism 2 also includes a collection and disinfection unit 22, which is arranged on the top of the urine collection unit 21. The collection and disinfection unit 22 is used for disinfection during the urine collection process.

[0044] As a further limitation of the collecting mechanism 2 of the present invention, the collecting and disinfecting unit 22 includes a liquid adding cylinder 2201, the bottom end of the liquid adding cylinder 2201 passes through the interior of the connecting cylinder 2101, the liquid adding cylinder 2201 is located between the two first rubber gaskets 2103, a liquid adding syringe 2202 is arranged on the top of the liquid adding cylinder 2201, the inner wall of the liquid adding cylinder 2201 is fixedly connected with a connecting ring 2203, the upper surface of the connecting ring 2203 is fixedly connected with one end of a reset spring 2204, the other end of the reset spring 2204 is fixedly connected with a closing plate 2205, the inner wall of the liquid adding cylinder 2201 is fixedly connected with a positioning ring 2206, the bottom surface of the positioning ring 2206 is in contact with the upper surface of the closing plate 2205, the upper surface of the closing plate 2205 is provided with a stepped groove 2207, the inner wall of the liquid adding cylinder 2201 is fixedly connected with a sealing block 2208, the sealing block 2208 is slidably connected to the inside of the stepped groove 2207, and a sealing column 2209 is fixedly connected to the upper surface of the closing plate 2205. The sealing column 2209 is clamped in the inside of the positioning ring 2206. An air vent 2210 is provided on the upper surface of the closing plate 2205. By setting up a collection and disinfection unit 22, a safe disinfection solution such as furacillin solution can be added to the inside of the connecting tube 2101. When the needle of the sampling syringe 2110 passes through the connecting tube 2101 and the connecting tube 2102 and enters the inside of the catheter 11, it will first come into contact with the disinfection and sterilization solution, thereby further preventing external bacteria from contaminating the catheter 11 during the urine sample collection process. At the same time, there is no need to repeatedly disinfect the catheter 11 during the collection process, which not only increases the convenience of collecting urine samples from the catheter 11, but also reduces the workload of medical staff to a certain extent.

[0045] The specific implementation of this embodiment is as follows: insert the liquid adding syringe 2202 without a needle into the liquid adding cylinder 2201, the liquid outlet of the liquid adding syringe 2202 will contact the closing plate 2205, and the downward pressure will force the return spring 2204 to shrink under the limit of the connecting ring 2203, so that the closing plate 2205 is out of contact with the positioning ring 2206, and at the same time, when the closing plate 2205 slides downward, the stepped groove 2207 is out of contact with the sealing block 2208, and at this time, the push rod of the liquid adding syringe 2202 is pushed to move the liquid adding syringe 2202. The disinfection and sterilization solution in the cylinder 2202 enters the liquid adding cylinder 2201 through the gap between the step groove 2207 and the step groove 2207 and the sealing block 2208, and finally flows into the gap between the two first rubber gaskets 2103 in the connecting cylinder 2101. As the closing plate 2205 moves downward, it also drives the sealing column 2209 and the positioning ring 2206 to separate, and then the air between the two first rubber gaskets 2103 passes through the vent hole 2210 and the gap between the sealing column 2209 and the positioning ring 2206. The gap between the two first rubber gaskets 2103 is discharged outward, so that the disinfection solution is filled between the two first rubber gaskets 2103 without too much air remaining. In addition, since the liquid outlet end of the liquid adding syringe 2202 is conical and the diameter is smaller than the diameter of the liquid adding syringe 2202, the liquid adding syringe 2202 will not block the air outlet at the sealing column 2209. When the liquid adding syringe 2202 is filled and removed, the reset spring 2204 resets and pushes the sealing plate 2205 to contact the positioning ring 2206 again to seal the liquid adding syringe 2202. 1. At this time, when the needle of the sampling syringe 2110 passes through the connecting cylinder 2101 and the connecting tube 2102 and enters the interior of the urinary catheter 11, it will first contact with the disinfection and sterilization solution between the two first rubber gaskets 2103, thereby further preventing external bacteria from contaminating the urinary catheter 11 during the urine sample collection process. At the same time, there is no need to repeatedly disinfect the urinary catheter 11 during the collection process, which not only increases the convenience of collecting urine samples from the urinary catheter 11, but also reduces the workload of medical staff to a certain extent.

[0046] Example 3: Please refer to Figure 7-Figure 9 The present invention provides a technical solution: a urinary catheter device for convenient urine collection. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A limiting mechanism 3 is arranged inside the urinary catheter 11. The limiting mechanism 3 is used in conjunction with the collecting mechanism 2. The limiting mechanism 3 is used to limit the position of the urinary catheter 11 in the patient's bladder.

[0047] As a further limitation of the limiting mechanism 3 of the present invention, the limiting mechanism 3 includes a liquid feeding pipe 301, which is clamped in the interior of the urinary catheter 11, and the outer surface of the guide head 13 is fixedly connected with an annular rubber bag 302, and the outer surface of the annular rubber bag 302 is fixedly connected with three positioning rubber bags 303, and the inner wall of each positioning rubber bag 303 is fixedly connected to the outer surface of the guide head 13, one end of the liquid feeding pipe 301 passes through the interior of one of the annular rubber bags 302, and the other end of the liquid feeding pipe 301 is fixedly connected with a docking pipe 304, and the inner wall of the docking pipe 304 is fixedly connected with a stabilizing ring 305, and the bottom surface of the stabilizing ring 305 is fixedly connected with a telescopic spring 306, and the inner wall of the docking pipe 304 is fixedly connected with a sealing plate 307, and the upper surface of the sealing plate 307 is provided with a liquid inlet 308, and the inner surface of the sealing plate 307 is clamped with a blocking plate 309, and the upper surface of the blocking plate 309 is connected to the telescopic spring 306. 6 is fixedly connected, and a plurality of water inlet grooves 310 are provided on the outer surface of the blocking plate 309. By setting the limiting mechanism 3, when the guide head 13 is extended into the patient's bladder to divert urine, not only can the positioning rubber bag 303 be expanded to limit the position of the guide head 13 and the catheter 11 in the patient's bladder, but also because there is a certain gap between the three positioning rubber bags 303, it can ensure that the urine at the bottom of the patient's bladder can also be smoothly guided out of the catheter 11 through the urine inlet hole 14, and the impurities in the urine will not be blocked by the positioning rubber bag 303. Accumulation, thereby reducing the friction between the catheter 11 and the impurities on the patient's urethra when the catheter 11 is taken out, which can not only improve the smoothness of the catheter 11 to a certain extent and reduce the pain of the patient, but also prevent the patient's urethra from being scratched and causing urethral infection, further improving the safety and comfort of the catheter 11 when it is used;

[0048] A reinforcing ring 311 is fixedly connected to the top of the butt joint pipe 304, and the inner wall of the reinforcing ring 311 is fixedly connected to the outer surface of the liquid delivery pipe 301. The reinforcing ring 311 can increase the connection firmness between the butt joint pipe 304 and the liquid delivery pipe 301, making it difficult for the butt joint pipe 304 and the liquid delivery pipe 301 to be loosened, thereby increasing the reliability of the cooperation between the butt joint pipe 304 and the liquid delivery pipe 301.

[0049] The bottom end of the docking tube 304 is threadedly connected to a sealing cover 312, and a plurality of anti-skid grooves 313 are provided on the outer surface of the sealing cover 312. The sealing cover 312 cooperates with the anti-skid grooves 313 to close the docking tube 304 when the docking tube 304 is not in use, thereby preventing liquid from leaking through the docking tube 304 and ensuring the pressure strength of the liquid inside the liquid delivery tube 301.

[0050] The specific implementation of this embodiment is as follows: after one end of the urinary catheter 11 enters the patient's bladder through the guide head 13, the sealing cover 312 is manually rotated through the anti-slip groove 313 to open the sealing cover 312, and then the water injection syringe is inserted into the butt joint 304. As the internal pressure of the butt joint 304 increases, the water flow will push the blocking plate 309 to move upward and force the telescopic spring 306 to shrink under the limit of the stabilizing ring 305. When the blocking plate 309 moves upward, the blocking plate 309 is out of contact with the sealing plate 307. At this time, the liquid can enter the liquid delivery tube 301 through the liquid inlet 308 on the sealing plate 307 and the water inlet groove 310 on the blocking plate 309, and finally flow into the three positioning rubber bags 303 and the annular rubber bag 302, so that the positioning rubber bag 303 and the annular rubber bag 302 expand, fix the position of the urinary catheter 11 and the guide head 13 inside the patient's bladder, and at the same time, due to the three positioning rubber bags 30 3, thereby ensuring that urine at the bottom of the patient's bladder can also be smoothly discharged from the catheter 11 through the urine inlet hole 14, and impurities in the urine will not accumulate in the patient's bladder due to the obstruction of the positioning rubber bag 303, thereby reducing the friction between the catheter 11 and the impurities on the patient's urethra when the catheter 11 is taken out, which can not only improve the smoothness of the removal of the catheter 11 to a certain extent and reduce the pain of the patient, but also prevent the patient's urethra from being scratched and causing urethral infection, further improving the safety and comfort of the catheter 11 when used. Finally, as the positioning rubber bag 303 and the annular rubber bag 302 expand to a certain extent, the water injection syringe stops injecting water. At this time, the elastic force provided by the telescopic spring 306 can be used to push the blocking plate 309 to contact the sealing plate 307 again, so that the sealing plate 307 blocks the water inlet trough 310, and the blocking plate 309 blocks the liquid inlet 308 to prevent liquid leakage.
