Abstract
Description
Technical Field
[0001] This utility model relates to the field of urinary catheter fixation technology, specifically to an external urinary catheter adjuster. Background Technology
[0002] Urinary catheterization involves inserting a catheter through the urethra into the bladder to drain urine. The purpose is to relieve urinary retention, obtain an uncontaminated urine sample for examination, measure residual urine, assess bladder temperature, capacity, and pressure, and administer contrast agents or medications to aid in diagnosis or treatment. One end of the catheter is inserted into the patient's bladder, and the other end is connected to a urine bag, which is usually secured to the patient's leg.
[0003] For some patients who are able to get out of bed, a certain length of the external urinary catheter needs to be left to allow for leg movement. However, if the external catheter is too long, it will hinder the patient's movement and may even cause traction or pulling on the catheter. If the external catheter is too short, it will restrict the patient's range of motion, and activities with large strides, such as climbing stairs, will also pull on the catheter, potentially causing injury. Therefore, there is an urgent need for an external urinary catheter adjuster to adjust the length of the external urinary catheter to meet the needs of different patients in different usage scenarios. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model proposes an external urinary catheter regulator to solve the above problems.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] The external urinary catheter regulator provided by this utility model includes:
[0007] Straps;
[0008] An adjustment seat is provided on one side of the strap. An adjustment groove is provided on the front side of the adjustment seat. Multiple positioning grooves are evenly distributed along the length of the bottom of the adjustment groove. A fixed winding post is provided on the front side of the adjustment seat next to the adjustment groove.
[0009] The movable winding column has an adjustment block at one end, which is slidably installed in the adjustment groove. The movable winding column has an axially opened insertion hole, and a pin is movably inserted into the insertion hole. The inner end of the pin can be inserted into any positioning groove, and the outer end of the pin is provided with a toggle part.
[0010] A urinary catheter, which is S-shaped and wrapped around the fixed and movable posts.
[0011] Furthermore, a rack parallel to the adjustment groove is provided on the front side of the adjustment seat next to the adjustment groove, and a gear meshing with the rack is provided on the movable spiral column.
[0012] Furthermore, two first limiting plates are spaced apart on the fixed winding post, and two second limiting plates are spaced apart on the movable winding post.
[0013] Furthermore, a first support block is provided at the outer end of the fixed winding post, and a first baffle is slidably installed on the first support block along the axial direction of the fixed winding post. The first baffle can be placed outside the space between the two first limiting plates. A second support block is provided at the outer end of the actuating part, and a second baffle is slidably installed on the second support block along the axial direction of the movable winding post. The second baffle can be placed outside the space between the two second limiting plates.
[0014] Furthermore, rollers are provided on the inner sides of both the first and second baffles.
[0015] Furthermore, a retaining ring is provided on the inner side of the end of the insertion hole away from the positioning groove, a boss is provided at the position of the pin inside the insertion hole, and a spring is sleeved on the part of the pin located between the boss and the retaining ring.
[0016] As can be seen from the above technical solution, the external urinary catheter regulator provided by this utility model is:
[0017] When the movable post moves away from the fixed post, it can bend and fold the catheter portion to shorten the length of the external catheter. Conversely, when the movable post moves closer to the fixed post, it will shorten the pull on the catheter, thus allowing for sufficient external catheter length. The patient can first pull the lever outward to pull the pin out of the positioning groove, then move the movable post to the appropriate position in the adjustment groove, and finally insert the pin into the corresponding positioning groove to adjust the catheter's mobility. This is convenient to operate and can fix the external catheter, preventing excessive shaking of the catheter from interfering with the patient's activities. Attached Figure Description

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0032] like Figure 1-4 As shown, the external urinary catheter regulator provided in this embodiment includes a strap 1, an adjustment seat 2, a movable winding post 3, and a urinary catheter 4.
[0033] The strap 1 can be wrapped and fixed around the patient's leg. The adjustment seat 2 is located on one side of the strap 1. The front side of the adjustment seat 2 has an adjustment groove 21. The adjustment groove 21 is strip-shaped. Multiple positioning grooves 211 are evenly distributed along the length of the bottom of the adjustment groove 21. A fixing post 22 is provided on the front side of the adjustment seat 2 next to the adjustment groove 21.
[0034] An adjusting block 31 is provided at one end of the movable rotating column 3. The adjusting block 31 is slidably installed in the adjusting groove 21. Specifically, as shown in the figure... Figure 4 As shown, the opening width of the adjusting groove 21 is smaller than its internal width, and the size of the movable winding post 3 is adapted to the opening width of the adjusting groove 21. The size of the adjusting block 31 is adapted to the internal width of the adjusting groove 21, and the adjusting block 31 is disc-shaped, allowing it to rotate axially within the adjusting groove 21. An insertion hole 32 is axially provided on the movable winding post 3, and a pin 33 is movably inserted into the insertion hole 32. The inner end of the pin 33 can be inserted into any positioning groove 211, and the outer end of the pin 33 is provided with a toggle part 34.
[0035] like Figure 4 As shown, preferably, a retaining ring 321 is provided on the inner side of the end of the insertion hole 32 away from the positioning groove 211, and a boss 331 is provided at the position of the pin 33 inside the insertion hole 32. A spring 37 is sleeved on the part of the pin 33 between the boss 331 and the retaining ring 321. The spring 37 can provide an elastic force to push the pin 33 into the positioning groove 211, so that the pin 33 can be stably inserted into the corresponding positioning groove 211 when it is not pulled outward, so as to keep the movable rotating post 3 from moving.
[0036] The urinary catheter 4 is S-shaped and wraps around the fixed winding post 22 and the movable winding post 3. When the movable winding post 3 moves away from the fixed winding post 22, it can partially bend and fold the urinary catheter 4 to shorten its length. Conversely, when the movable winding post 3 moves closer to the fixed winding post 22, it will shorten the pull on the urinary catheter 4, thus reserving enough length for the external urinary catheter 4. The patient can first pull the actuating part 34 outward to pull the pin 33 out of the positioning groove 211, then move the movable winding post 3 to the appropriate position in the adjustment groove 21, and finally insert the pin 33 into the corresponding positioning groove 211 to adjust the mobility of the urinary catheter 4. This is convenient to operate and can fix the external urinary catheter 4, preventing excessive shaking of the urinary catheter 4 from interfering with the patient's activities.
[0037] In one embodiment, a rack 23 parallel to the adjustment groove 21 is provided on the front side of the adjustment seat 2, next to the adjustment groove 21, and a gear 35 meshing with the rack 23 is provided on the movable winding column 3. In actual use, when the movable winding column 3 moves and adjusts within the adjustment groove 21, the gear 35 and the rack 23 will mesh and drive the movable winding column 3 to rotate. When the movable winding column 3 rotates, it can promote the movement of the catheter 4 it is in contact with, reduce the friction between the movable winding column 3 and the catheter 4 during movement, and prevent the catheter 4 from being damaged by excessive friction. When the movable winding column 3 moves away from the fixed winding column 22 to bend and shorten the catheter 4, it can rotate synchronously and drive the catheter 4 to be drawn between the movable winding column 3 and the fixed winding column 22. When the movable winding column 3 moves closer to the fixed winding column 22 to increase the mobility of the catheter 4, it can rotate synchronously and assist in bringing the catheter 4 out.
[0038] Preferably, two first limiting plates 221 are spaced apart on the fixed winding post 22, and two second limiting plates 36 are spaced apart on the movable winding post 3. The catheter 4 can be placed between the two first limiting plates 221 and the two second limiting plates 36 respectively to prevent the catheter 4 from deviating during adjustment.
[0039] Furthermore, a first support block 222 is provided at the outer end of the fixed winding post 22. A first baffle 223 is slidably mounted on the first support block 222 along the axial direction of the fixed winding post 22. The first baffle 223 can be positioned outside the space between the two first limiting plates 221. A second support block 341 is provided at the outer end of the actuating part 34. A second baffle 342 is slidably mounted on the second support block 341 along the axial direction of the movable winding post 3. The second baffle 342 can be positioned outside the space between the two second limiting plates 36. The first baffle 223 and the second baffle 342 can prevent the catheter from disengaging between the two first limiting plates 221 or the two second limiting plates 36 during adjustment. When it is necessary to install or remove the catheter 4, it is only necessary to slide the first baffle 223 and the second baffle 342 away from the outside of the first limiting plate 221 and the outside of the second limiting plate 36.
[0040] like Figure 4 As shown, preferably, rollers 5 are provided on the inner sides of both the first baffle 223 and the second baffle 342 to reduce the friction between the first baffle 223 and the second baffle 342 and the catheter 4.
[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model, and they should all be covered within the scope of the claims and description of this utility model.
