Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a binding type urinary catheter fixator. Background Technique

[0002] A urinary catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC), which can be inserted into the bladder through the urethra to guide urine to flow out. After the urinary catheter is inserted into the bladder, there is an air bag near the head end of the urinary catheter to fix the urinary catheter in the bladder and prevent it from slipping out easily. The drainage tube is connected to a urine bag to collect urine. For urological surgeons, almost all surgeries require indwelling urinary catheters. Some patients need to indwell urinary catheters for a long time. A long part of the urinary catheters of these patients is often externally placed and in a movable state, which brings inconvenience to life. If not careful, it is easy to cause pain and urethral injury by pulling.

[0003] Currently, in clinical practice, generally, adhesive tape is used to wrap around the urinary catheter and then fixed to the patient's thigh side. However, as the patient moves, after being fixed by the adhesive tape wrapping method, it is inconvenient to adjust the fixing angle of the urinary catheter, which brings discomfort to the patient to a certain extent. At the same time, the patient's skin sweats, and the adhesive tape is very easy to fall off. Repeatedly tearing and pasting the adhesive tape, the adhesiveness of the adhesive tape is not good, and replacing it again increases the medical cost. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a binding type urinary catheter fixator to solve the technical problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A binding type urinary catheter fixator, including a fixing band and a seat body. A gear is movably installed in the middle of the seat body, and fixing blocks are fixedly installed at both ends of the fixing band. A clamping block is movably installed at one end of the fixing block, and a limiting block is fixedly installed at one end of the clamping block. The fixing block and the clamping block are connected by a spring. Sliding grooves are opened at both ends of the fixing band, and sliders are movably installed inside the sliding grooves. A guiding groove matched with the limiting block is opened at one end of the slider.

[0006] By adopting the above technical scheme, the limiting block is limited by the guiding groove, so that the clamping block moves along the fixing block to both sides, releasing the limit on the gear, thereby facilitating the patient to adjust the fixing angle of the urinary catheter by rotating the elastic clip in different activity scenarios, and thus alleviating the discomfort of the patient to a certain extent.

[0007] The utility model is further set as that a clamping interface is opened at one end of the fixing band, and a protruding block is fixedly installed at the other end of the fixing band. The number of the clamping interfaces is set in multiple groups.

[0008] By adopting the above technical solution, the fixing method of inserting the raised block into the card interface is used to replace the traditional tape fixing method, thereby preventing the problem that the adhesive tape is likely to fall off due to the patient's sweating and the viscosity is reduced due to repeated tearing of the adhesive tape, resulting in poor fixing effect, and strengthening the fixing effect of the catheter.

[0009] The utility model is further arranged such that one end of the gear is fixedly installed with an elastic clip, and guiding parts are provided at both ends of the elastic clip. One end of the elastic clip is provided with a flared part, and one end of the fixing belt is fixedly installed with a ring.

[0010] By adopting the above technical solution, guiding parts are provided at both ends of the elastic clip, so that the catheter can more easily be clamped into the clamping space of the elastic clip through the flared part formed by the guiding parts, facilitating the fixing of the catheter.

[0011] The utility model is further arranged such that one end of the slider is provided with a mounting hole, and a rotating shaft is movably installed on one side of the mounting hole, and a stop block is fixedly installed on one side of the rotating shaft.

[0012] By adopting the above technical solution, by installing the stop block, the position of the slider is limited and locked by the stop block, preventing the slider from loosening and causing the gear to slip off, thereby reducing the fixing effect of the elastic clip on the catheter, and at the same time achieving the purpose of quickly adjusting the elastic clip.

[0013] The utility model is further arranged such that one end of the stop block is arranged as an arc surface, and a clamping groove matched with the stop block is provided at one end of the slider.

[0014] By adopting the above technical solution, by providing the clamping groove, the arc surface of the clamping groove can provide better surface contact, reduce friction and wear with the stop block, provide stable connection performance, and ensure the tight fit between the stop block and the clamping groove.

[0015] The utility model is further arranged such that one end of the clamping block is arranged as a tapered shape matched with the gear, and both sides of the limiting block are arranged as arc surfaces.

[0016] By adopting the above technical solution, by arranging arc surfaces on both sides of the limiting block, the curve shape of the arc surface can make the stress distribution of the limiting block more uniform, reduce stress concentration points, thereby improving the strength and durability of the structure of the limiting block.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] The utility model is provided with a gear, a spring, a clamping block, a limiting block, etc. By pulling the stop block, the stop block rotates around the rotating shaft to release the limit on the sliders at both ends of the seat body. Then, gently press the sliders to slide along the sliding groove towards the inner side of the seat body, so that the guiding groove limits the limiting block, and the clamping block moves towards both sides along the fixed block to release the limit on the gear. Thus, it is convenient for patients to adjust the fixing angle of the urinary catheter through the rotation angle of the elastic clip in different activity scenarios, thereby alleviating the discomfort of patients to a certain extent. By setting a fixing belt to replace the adhesive tape fixing method, the problems of easy falling off of the adhesive tape due to sweating of patients and poor fixing effect caused by repeated tearing of the adhesive tape to reduce its viscosity are prevented.

Fixing blocks 9 are fixedly installed at both ends of the fixing belt 1. A clamping block 14 is movably installed at one end of the fixing block 9. A limiting block 15 is fixedly installed at one end of the clamping block 14. The fixing block 9 and the clamping block 14 are connected by a spring 10. Sliding grooves 11 are formed at both ends of the fixing belt 1. Sliders 12 are movably installed inside the sliding grooves 11. A guiding groove 13 that matches the limiting block 15 is formed at one end of the slider 12. By pulling the blocking block 7, the limiting of the sliders 12 at both ends of the seat body 19 by the blocking block 7 with the rotating shaft 16 as the rotation center is released. Then, the slider 12 is gently pressed to slide along the sliding groove 11 towards the inside of the seat body 19, so that the guiding groove 13 limits the limiting block 15, causing the clamping block 14 to move towards both sides along the fixing block 9, releasing the limitation on the gear 8, so as to facilitate the adjustment of the fixing angle of the catheter by rotating the elastic clip 4 at different activity scenarios for the patient.

[0027] Please refer to Figure 1 , a clamping interface 2 is formed at one end of the fixing belt 1. A protruding block 3 is fixedly installed at the other end of the fixing belt 1. The number of clamping interfaces 2 is set in multiple groups. The fixing method of inserting the protruding block 3 into the clamping interface 2 replaces the traditional adhesive tape fixing method, thereby preventing the problem that the adhesive tape is likely to fall off due to the patient sweating and the viscosity is reduced due to repeated tearing of the adhesive tape, resulting in poor fixing effect, and strengthening the fixing effect of the catheter.

[0028] Please refer to Figure 1 , an elastic clip 4 is fixedly installed at one end of the gear 8. Guiding parts 5 are formed at both ends of the elastic clip 4. An expanding opening part 6 is formed at one end of the elastic clip 4. A ring 20 is fixedly installed at one end of the fixing belt 1. Due to the guiding parts 5 formed at both ends of the elastic clip 4, the catheter can more easily be clamped into the clamping space of the elastic clip 4 through the expanding opening part 6 formed by the guiding parts 5, facilitating the fixing of the catheter.

[0029] Please refer to Figure 4 , an installation hole 17 is formed at one end of the slider 12. A rotating shaft 16 is movably installed on one side of the installation hole 17. A blocking block 7 is fixedly installed on one side of the rotating shaft 16. By installing the blocking block 7, the position of the slider 12 is limited and locked by the blocking block 7, preventing the slider 12 from loosening and causing the gear 8 to slip off, reducing the fixing effect of the elastic clip 4 on the catheter, and simultaneously achieving the purpose of quickly adjusting the elastic clip 4.

[0030] Please refer to Figure 4 , one end of the blocking block 7 is arc-shaped. A clamping groove 18 that matches the blocking block 7 is formed at one end of the slider 12. By forming the clamping groove 18, the arc surface of the clamping groove 18 can provide better surface contact, reduce the friction and wear with the blocking block 7, provide stable connection performance, and ensure the tight fit between the blocking block 7 and the clamping groove 18.

[0031] Please refer to Figure 2, one end of the clamping block 14 is arranged in a sharp conical shape for mating with the gear 8, and both sides of the limiting block 15 are arranged in an arc shape. Through the arc-shaped arrangement of both sides of the limiting block 15, the curve shape of the arc surface can make the stress distribution of the limiting block 15 more uniform, reduce the stress concentration points, and thus improve the strength and durability of the structure of the limiting block 15.

[0032] The working principle of the present utility model is as follows: When in use, first, according to the thigh circumference of the patient, the protruding block 3 is inserted into the clamping interface 2 at the corresponding position, so as to fix the fixing belt 1 on the side of the patient's thigh, and the excess part of one end of the fixing belt 1 is bound through the loop 20 to prevent scratching the patient's skin. Then, the catheter is inserted into the elastic clip 4 along the guiding part 5 for fixation. By pulling the blocking block 7, the blocking block 7 rotates around the rotating shaft 16 to release the limit on the sliders 12 at both ends of the seat body 19. Then, gently press the sliders 12 to slide inward along the sliding groove 11 towards the seat body 19, so that the guiding groove 13 limits the limiting block 15, making the clamping block 14 move towards both sides along the fixing block 9, releasing the limit on the gear 8, so as to facilitate the patient to adjust the fixing angle of the catheter through the rotation angle of the elastic clip 4 in different activity scenarios. After the adjustment is completed, stop pressing the sliders 12, so that the clamping blocks 14 at both ends reset under the action of the spring 10 and continue to limit and fix the gear 8 again. At this time, the sliders 12 are ejected and reset under the extrusion of the limiting block 15, and the blocking block 7 is rotated to the inside of the clamping groove 18, so that the blocking block 7 is limited again to lock the position of the sliders 12, and that's it.
