Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a self-lubricating one-way push-type urinary catheter clamp. Background Art

[0002] As we all know, a urinary catheter is a tube that is inserted from the urethra into the bladder to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) that can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, there is an air bag near the head of the catheter to fix the catheter in the bladder and prevent it from coming out. The drainage tube is connected to a urine bag to collect urine. When using it as a whole, the most important thing is how to effectively and correctly insert the urinary catheter into the urethra.

[0003] At present, the existing urinary catheters are basically held by the doctor, and then disinfected and smeared with silicone oil for lubrication. This operation makes the catheterization operation more complicated, prolongs the duration of the catheterization operation, and is not conducive to a one-time quick completion.

[0004] Therefore, it is necessary to provide an instrument that can quickly help doctors complete urinary catheterization. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a self-lubricating one-way push-type urinary catheter clamp which can effectively improve the intubation efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A self-lubricating one-way push-type catheter clamp comprises a clamp tube and tweezers, wherein the clamp tube is in a "C" shape, and two ends of the clamp tube are respectively and evenly provided with silicone oil cotton balls and iodine cotton balls along the tube wall, and an active opening is respectively provided on the upper and lower end faces of the middle part of the clamp tube, and two mutually symmetrical slide grooves are provided at the inner wall of the port of the active opening, and a slider is provided at the clamping end of the tweezers, and the two ends of the slider are placed in the slide groove, and a push plate is hinged on the slider, and the push plate is in an inclined state, and a torsion spring is provided at the hinge of the push plate and the slider, and the torsion of the torsion spring needs to be greater than the gravity of the push plate and less than the friction between the push plate and the catheter, and under the action of the torsion spring, the bottom end of the push plate keeps contacting the catheter.

[0008] Preferably, a blocking block is provided at the lower end of the sliding block so that the pushing plate can only rotate to a 90° position.

[0009] Preferably, the silicone oil cotton balls and iodine cotton balls are covered with a layer of film that can be torn off manually.

[0010] Preferably, an extension portion is provided at the bottom of the push plate.

[0011] Due to the adoption of the above scheme, the utility model relies on the clamp tube to clamp the urinary catheter, so as to avoid the operator's hands from excessively touching the urinary catheter and avoiding excessive exposure of the urinary catheter after disinfection, thereby reducing the risk of urinary tract infection in patients; at the same time, silicone oil cotton balls and iodine cotton balls are respectively arranged at both ends of the clamp tube, so that when the urinary catheter moves in the clamp tube, one end can be disinfected and the other end can be coated with lubricant, so that the whole process can be completed synchronously as the urinary catheter is pushed in the clamp tube, making the whole intubation process smoother and more efficient, and the silicone oil cotton balls and iodine cotton balls are evenly arranged on the inner wall of the clamp tube, so that the disinfection and lubrication will be more uniform, ensuring that the disinfection and lubrication are sufficient.

[0018] like Figures 1 to 3 As shown, a self-lubricating one-way push-type catheter clamp provided in the present embodiment comprises a clamp tube 1 and tweezers 2, the clamp tube 1 is in a "C" shape, and the two ends of the clamp tube 1 are respectively and evenly provided with silicone oil cotton balls 3 and iodine cotton balls 4 along the tube wall, and the upper and lower end surfaces of the middle part of the clamp tube 1 are respectively provided with a movable opening 5, and the inner wall of the port of the movable opening 5 is provided with two mutually symmetrical slide grooves 6, and the clamping end of the tweezers 2 is provided with a slider 7, and the two ends of the slider 7 are placed in the slide groove 6, and a push plate 8 is hinged on the slider 7, and the push plate 8 is in an inclined state, and a torsion spring 9 is provided at the hinge of the push plate 8 and the slider 7, and the torsion force of the torsion spring 9 needs to be greater than the gravity of the push plate 8 and less than the friction between the push plate 8 and the catheter 100, and under the action of the torsion spring 9, the bottom end of the push plate 8 keeps touching the catheter 100.

[0019] This embodiment relies on the clamp tube 1 to clamp the urinary catheter 100, so as to prevent the operator's hands from excessively touching the urinary catheter 100 and to prevent the urinary catheter 100 from being overly exposed after disinfection, thereby reducing the risk of urinary tract infection in patients; at the same time, silicone oil cotton balls 3 and iodine cotton balls 4 are respectively provided at both ends of the clamp tube 1, so that when the urinary catheter 100 moves in the clamp tube 1, one end can be disinfected and the other end can be coated with lubricant, so that the whole process can be completed synchronously with the urinary catheter 100 being pushed in the clamp tube 1, making the whole intubation process smoother and more efficient, and the silicone oil cotton balls 3 and iodine cotton balls 4 are evenly arranged on the inner wall of the clamp tube 1, so that the disinfection and lubrication will be more uniform, ensuring that the disinfection and lubrication are sufficient.

[0020] During the specific intubation operation of this embodiment, the urinary catheter 100 is first inserted into the clamp tube 1 from the end provided with the iodine cotton ball 4, and the clamp tube 1 is in a "C" shape. The diameter of the clamp tube 1 needs to be tightly matched with the diameter of the urinary catheter 100, that is, after the urinary catheter 100 is inserted, the clamp tube 1 will give the urinary catheter 100 a certain elastic clamping force, so that when the urinary catheter 100 is pushed, on the one hand, the assembly between the clamp tube 1 and the urinary catheter 100 is maintained, and on the other hand, the silicone oil cotton ball 3 and the iodine cotton ball 4 can be scraped, and then the iodine and silicone oil can seep out so as to be applied to the urinary catheter 100. When the catheter 100 is inserted into the clamp tube 1, the iodine cotton ball 4 will be scraped first to disinfect the inserted catheter 100. As the catheter 100 continues to be pushed, the catheter 100 will contact the pushing plate 8. At this time, the pushing plate 8 is in a vertical direction under the action of the torsion spring 9. If the catheter 100 is pushed continuously, the two pushing plates 8 will be pushed apart, and the bottom of the pushing plate 8 will be pressed against the catheter 100. At this time, the preliminary installation of the catheter 100 is completed, and there is no need to push the catheter 100 externally afterwards. When it is necessary to continue pushing the catheter 100, grasp the tweezers 2 and then move the tweezers 2 toward the iodine cotton ball 4, so that the slider 7 slides along the slide groove 6 toward the end of the iodine cotton ball 4. At this time, the pushing plate 8 is tilted toward the silicone oil cotton ball 3, and the torsion spring 9 is not strong enough to clamp the catheter 100 and move together. Therefore, during the sliding process of the slider 7, the pushing plate 8 rotates along the hinge point and then moves to the other end as the slider 7 slides. Then, the gripping forceps 2 slide back, and after the slider 7 slides back, the push plate 8 and the catheter 100 will rotate toward the end of the iodine cotton ball 4 under the resistance of the push plate 8, so that the push plate 8 presses the catheter 100 at both ends of the catheter 100, and the catheter 100 itself has a certain flexibility, so as to form a clamping effect on the catheter 100, and then as the forceps 2 move, the catheter 100 will be clamped and pushed to the other end, and the catheter 100 can be pushed in the clamp tube 1 repeatedly. Among them, when the catheter 100 is gradually pushed out from the other end of the clamp tube 1, it will be evenly coated with silicone oil, so that the catheter can be directly inserted to avoid the long-term exposure of the pushed catheter 100.

[0021] Furthermore, in order to prevent the push plate 8 from rotating to the other side, that is, to prevent the push plate 8 from over-rotating, a blocking block 10 is provided at the lower end of the slider 7 of this embodiment, so that the push plate 8 can only rotate to a 90° position, thereby ensuring that the push plate 8 does not rotate beyond the vertical angle, thereby ensuring the normal operation of the push plate 8.

[0022] Furthermore, in order to prevent the silicone oil cotton balls 3 and iodine cotton balls 4 from being exposed to the air when not in use, a manually removable coating 11 is laid on the silicone oil cotton balls 3 and iodine cotton balls 4 in this embodiment. When performing the intubation operation, it is only necessary to tear off the coating 11 before performing the subsequent operation.

[0023] Furthermore, in order to enhance the clamping force of the pushing plate 8 on the urinary catheter 100, an extension portion 12 is provided at the bottom of the pushing plate 8 of this embodiment, so as to increase the clamping force of the pushing plate 8 by increasing the contact area.

[0024] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
