Description

Technical Field

[0001] The present invention relates to the technical field of urology surgery, in particular to a clinical catheter assembly device for urology surgery. Background Art

[0002] A urinary catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is a tube made of flexible materials such as natural rubber and silicone rubber. It can be inserted into the bladder through the urethra to drain urine. When installing the catheter, the end of the catheter is inserted from the patient's urethra to the bladder. By observing the urine flow, it is determined whether the ball head of the catheter end has entered the bladder. After urine flow, the catheter is controlled to continue to penetrate 3-5 cm, and the water bag is further filled with liquid to expand the water bag and get stuck in the patient's bladder to prevent the catheter from falling off, thereby achieving the fixation of the catheter.

[0003] In the prior art, during the installation of a urinary catheter, due to the presence of a certain distance between the ball head and the water bag of the urinary catheter, the urinary catheter needs to be further inserted after urination to ensure that the water bag completely enters the bladder. However, the further insertion distance into the urethra is generally manually controlled, and the insertion depth is easily inaccurate based on experience and feeling. If the insertion depth is too deep, it is easy to damage the bladder wall, while if the insertion depth is too shallow, it is easy to cause the water bag to expand and damage the urethra, increasing the patient's pain.

[0031] The detection mechanism includes a valve block 200 that is movably connected to the inside of the hose 100. It should be noted that the hose 100 is provided with a drainage ball head 109 and the part of the internal tube body that is movably connected to the valve block 200 is made of a tough material to avoid deformation and leakage, while reducing the impact of bending on fluidity and ensuring the drainage effect. The hose 100 is provided with a valve tube 104, and the side wall of the valve tube 104 is provided with a flow hole 103. The side wall of the valve block 200 is provided with a flow hole 201 that cooperates with the flow hole 103. The inner side wall of the hose 100 is provided with a detection hole 102 that is connected to the outside. The valve block 200 is also provided with a connecting hole 3 202 that cooperates with the detection hole 102. The hose 100 is provided with a sealed cavity 106. The liquid guide tube 108 is connected to the inside of the sealed cavity 106. The sealed cavity 106 is connected to the inside of the liquid bag 105. The interior of the fixed frame 300 is provided with a sampling mechanism.

[0032] Reference Figure 2-3 The valve block 200 is a multi-section design, and the diameter of each section of the valve block 200 gradually increases along the direction from the drainage ball head 109 to the fixed frame 300. The end of the valve block 200 with the smallest diameter is movably connected to the valve tube 104, and the sealing chamber 106 is designed to cooperate with the section of the valve block 200 with the largest diameter.

[0033] Reference Figure 4-7The sampling mechanism includes a sealed chamber 303 opened inside the fixed frame 300, a slider 307 is connected to the interior of the fixed frame 300, a collection bottle 302 is clamped at the bottom outlet of the sealed chamber 303, a piston block 306 is connected to the interior of the sealed chamber 303, the top of the piston block 306 is connected to the piston rod 305 connected to the fixed frame 300, a sampling sleeve 313 is connected to the fixed frame 300, and the interior of the sampling sleeve 313 is connected to multiple groups of connecting rods 314 connected to the piston block 306, a return spring 316 is provided between the connecting rod 314 and the sampling sleeve 313, a guide tube 308 is provided inside the fixed frame 300, a liquid path groove 309 connecting the guide tube 308 and the hose 100 is provided inside the slider 307, and a buffer component and an emptying component are also provided inside the fixed frame 300.

[0034] Furthermore, the buffer assembly includes a magnetic ring 1 315 arranged at the bottom of the sampling sleeve 313, a magnetic ring 2 317 cooperating with the magnetic ring 1 315 is arranged at the top of the sealed chamber 2 303, a one-way air intake valve 318 and a one-way exhaust valve 2 320 are arranged on the side wall of the sealed chamber 2 303, the one-way air intake valve 318 is positioned close to the top of the sealed chamber 2 303, the one-way exhaust valve 2 320 is positioned close to the bottom of the sealed chamber 2 303, and a one-way exhaust valve 1 319 is arranged at the top of the sealed chamber 2 303.

[0035] It should be noted that the internal diameters of the one-way air intake valve 318 and the one-way exhaust valve 2 320 are the same, and the internal diameter of the one-way air intake valve 318 is larger than the internal diameter of the one-way exhaust valve 1 319. When the piston block 306 moves downward, air can be quickly taken in through the one-way air intake valve 318 to balance the pressure and reduce resistance. When the piston block 306 rises, it can provide resistance and exhaust slowly to avoid the negative pressure from sucking up the urine sample too quickly and causing pressure on the patient.

[0036] Reference Figure 4-6 The emptying component includes a valve tube 2 311 arranged on the side wall of the slider 307, and a drainage tube 304 is provided at the bottom of the fixed frame 300. The valve tube 2 311 is movably connected to the hose 100 and the drainage tube 304 at the same time. The top of the valve tube 2 311 is a closed design, and the bottom of the valve tube 2 311 is an open design. The side wall of the valve tube 2 311 is provided with a connecting hole 4 312 that cooperates with the hose 100.

[0037] It should be noted that the portion where the valve tube 2 311 is movably connected to the hose 100 and the drainage tube 304 is made of a tough material, thereby avoiding leakage due to deformation.

[0038] Reference Figure 4-6The top of the slider 307 is provided with a bend extending into the interior of the sealed chamber 2 303, and a spring is provided between the top of the slider 307 and the fixed frame 300. The bottom of the slider 307 is provided with an air path groove 310, and the air path groove 310 is L-shaped. One end of the air path groove 310 is toward the guide tube 308, and the other end of the air path groove 310 is toward the interior of the urine storage tank 301.

[0039] It should be noted that the urine storage box 301 is made of transparent plastic material, and scale lines are set on the surface of the urine storage box 301, which can be used to observe the amount of urine inside the urine storage box 301.

[0040] The workflow of the urology clinical catheter assembly device is as follows:

[0041] When the patient is catheterized, the drainage ball head 109 is inserted along the patient's urethra. During the process of the drainage ball head 109 and the hose 100 entering the bladder from the urethra, in the initial state, refer to Figure 2 , the flow hole 201 and the flow hole 103 are not connected, and the communication hole 302 is connected to the detection hole 102. Therefore, when the drainage ball head 109 enters the bladder, urine will not enter the hose 100 through the flow hole 103, so the urine storage box 301 will not discharge urine. Only when the liquid bag 105 completely enters the bladder, the hose 100 is further inserted until the detection hole 102 enters the bladder, and the urine inside the bladder enters the hose 100 through the detection hole 102 under the action of pressure. Stable urine discharge is observed through the urine storage box 301, and it can be judged that the drainage ball head 109 and the liquid bag 105 have entered the bladder. At this time, physiological saline is injected into the catheter 108 from the injection port 107 through the syringe. After the physiological saline enters the sealed cavity 106 through the catheter 108, the sealed cavity 106 and the liquid bag 105 are connected. The connection inflates the sac 105 so that it can form a snap-fit ​​mechanism in the bladder, keeping the drainage ball head 109 in the bladder to maintain catheterization work and prevent the drainage ball head 109 and the hose 100 from slipping out of the bladder. While the sealing cavity 106 is filled with physiological saline, the pressure will also push the valve block 200 away from the drainage ball head 109, so that the valve block 1200 moves to the flow hole 201 and overlaps with the flow hole 103 and is connected. The connecting hole 3 202 is separated from the connection with the detection hole 102 under the movement of the valve block 200. At this time, the urine inside the bladder only enters through the drainage ball head 109, and through the connection between the flow hole 103 and the flow hole 2 201, the urine further enters the hose 100 to realize urination, thereby ensuring single-channel urination, ensuring the stability of urination, and reducing the risk of urinary tract infection.

[0042] When urinating through the detection hole 102, since there are more drainage holes 101 opened on the surface of the drainage ball head 109 in the traditional scheme, the urine remaining in the urethra can also enter through the drainage hole 101. However, when urinating only through the detection hole 102 during the intubation process, since the detection hole 102 is only opened on the side wall of the hose 100 and can maintain close contact with the inner wall of the urethra through the pressure of the urethral muscle tissue during the entry process, it is difficult for urine in the urethra to enter through the detection hole 102. Only when the detection hole 102 enters the bladder will the urine enter from the detection hole 102 to realize urination, thereby avoiding the influence of the residual urine in the urethra on the observation of urination.

[0043] Compared with traditional urinary catheter assemblies, during the intubation process, this solution uses the detection hole 102 set on the side of the liquid sac 105 away from the drainage ball head 109 to discharge urine, thereby automatically detecting whether the liquid sac 105 has completely entered the bladder, ensuring the liquid sac 105 is filled and fixed, and at the same time avoiding the influence and interference of residual urine in the urethra on the intubation, avoiding accidental damage to the patient's urethra and bladder during the intubation and liquid sac 105 filling process, and during the subsequent liquid sac 105 filling and installation, through the connection between the liquid sac 105 and the sealing cavity 106, the valve block 200 can be pushed to move to change the connection state of the detection hole 102, thereby realizing single-channel urination of the drainage ball head 109, ensuring the stability of urine drainage, and reducing the risk of urinary tract infection.

[0044] Traditionally, urine samples are collected directly from urine collection bags or from the end of a urine catheter. However, samples collected from urine collection bags are prone to sedimentation and are contaminated by mixing with multiple urine samples, which is not conducive to regular extraction and testing. In addition, when collecting samples from collection bags and the end of a urine catheter, urine is prone to leakage during contact collection, increasing the workload of staff.

[0045] When the present invention is to sample urine, the sampling sleeve 313 is lifted up until the magnetic ring 1 315 is attracted to contact with the magnetic ring 2 317 to fix the sampling sleeve 313. At this time, the return spring 316 drives the connecting rod 314 to rise under the elastic force, and further drives the piston block 306 to rise. The pressure between the piston block 306 and the collection bottle 302 becomes smaller. At the same time, during the upward movement of the piston block 306, the gas between the top of the piston block 306 and the sealed chamber 2 303 can be slowly discharged through the smaller diameter of the one-way exhaust valve 1 319, and then the urine sample from the hose 100 to the inside of the bladder can be slowly sucked in through the liquid path groove 309 and the guide tube 308 through the negative pressure effect, and is away from the hose 100 through the guide tube 308. One end is discharged into the interior of the collection bottle 302 to achieve contactless urine sampling. When the piston block 306 moves up to contact the slider 307 and drives the slider 307 to move up, the upward movement of the slider 307 can make the liquid path groove 309 move up to be disconnected from the connection with the guide tube 308, and stop sampling the liquid. At the same time, the air path groove 310 moves up to be connected with the guide tube 308. The negative pressure between the top of the piston block 306 and the sealed chamber 2 303 makes the external gas be sucked into the sealed chamber 2 303 and the collection bottle 302 through the air path groove 310 and the guide tube 308 after the liquid sampling is completed at the end of the sampling, thereby achieving the drainage of the guide tube 308, reducing the internal liquid residue, and thereby reducing the cross contamination of samples in subsequent sampling, while also ensuring the cleanliness after sampling.

[0046] It should be noted that, at the end of sampling, when the piston block 306 drives the slider 307 to rise, the valve tube 2 311 moves upward synchronously with the slider 307, so that the connecting hole 4 312 moves to the inside of the hose 100 and communicates with the hose 100, so that the hose 100 is connected with the drainage tube 304 through the connecting hole 4 312 and the valve tube 2 311 to achieve urination. After the sampling is completed, the collection bottle 302 is replaced. When sampling is performed again later, the sampling sleeve 313 is pushed downward to the lowest point to separate the magnetic ring 1 315 from the adsorption of the magnetic ring 2 317. When the sampling sleeve 313 moves downward, it can synchronously push the piston rod 305 and the piston block 306 to move downward, and the urine is discharged through the one-way exhaust valve 2 320. The second valve 311 moves downward, causing the fourth communication hole 312 to be disconnected from the hose 100, so that the hose 100 is connected with the liquid path groove 309 and the guide tube 308, so that the negative pressure inside the collection bottle 302 directly acts on the hose 100 for sampling. Then, the sampling sleeve 313 is pulled to the highest point again, so that the magnetic ring 1 315 and the magnetic ring 2 317 are adsorbed and fixed, and sampling is performed according to the above sampling process.

[0047] It should be noted that, in the initial state, the piston block 306 is located above the inside of the sealed chamber 303, pushing the slider 307 to keep the air path groove 310 connected with the guide tube 308. At this time, the hose 100 forms a passage with the drainage tube 304 through the connecting hole 4 312 and the valve tube 2 311, which is convenient for intubation and observation of urine. Each time sampling is performed, the negative pressure inside the collection bottle 302 is accumulated by pressing down and lifting the sampling sleeve 313, and then the valve tube 2 311 is moved to switch the connection between the hose 100 and the liquid path groove 309 or the drainage tube 304 to achieve sampling.

[0048] During the sampling process, negative pressure is generated inside the collection bottle 302 by moving the sampling sleeve 313 downward and upward, and the movement of the slider 307 makes the hose 100 and the inside of the collection bottle 302 in one-way communication at the early stage of the sampling process. The elasticity of the return spring 316 and the diameter design of the one-way exhaust valve 319 slowly draw urine samples from the urethra and bladder. The urine sample will not come into contact with other parts inside the fixing frame 300, thus avoiding urine contamination. In addition, the sample taken is fresh, avoiding the collection of deposited urine samples. During this period, the piston block 306 drives the slider 307 to move upward, changing the internal connection state, so that the guide tube 308 is connected with the air path groove 310, and air is inhaled at the end of sampling to drain the guide tube 308, thereby reducing the internal liquid residue and thus reducing the cross contamination of the subsequent samples. At the same time, the hose 100 and the drainage tube 304 are restored to connection, which can facilitate the collection of fresh urine samples without affecting the normal urination work, reduce the risk of contact and leakage, improve the cleanliness of sample collection, and reduce the psychological pressure of the staff.

[0049] It should be noted that when the piston block 306 moves downward to discharge the gas through the one-way exhaust valve 2 320, the gas will be compressed inside the collection bottle 302. By designing the volume ratio of the sealed chamber 2 303 and the internal volume of the collection bottle 302, a suitable volume of sample can be taken inside the collection bottle 302, thereby achieving quantitative sampling, and there will be no risk of leakage after sampling.

[0050] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
