Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to an adjustable catheter fixation device. Background Technology
[0002] Currently, in urological nursing, indwelling catheterization is a routine procedure. When a catheter is left in place for an extended period of time, it needs to be secured to improve its stability and facilitate both the doctor and the patient.
[0003] Patent CN219963707U discloses a catheter fixation strap, relating to the field of medical device technology. It solves the problem of inconvenience in using existing technologies that rely on breathable medical tape or 3M transparent dressing adhesive for secondary catheter fixation. The fixation strap includes a connecting strap, a first fixation part, and a second fixation part. In use, the connecting strap is wrapped around the patient's leg, and then the catheter is passed through the first and second fixation parts. The second fixation part is then connected to the first fixation part to limit the catheter's position on the connecting strap, thus achieving secondary fixation of the catheter and avoiding the inconvenience of using breathable medical tape or 3M transparent dressing adhesive. However, this solution has the following problems:
[0004] The catheter is relatively long and is used to connect the urine bag to the genitals. During use, the catheter may become tangled, and patients may pull on it while moving. The length of the catheter between the genitals and the fixation strap needs to be adjusted. For this solution, the catheter fixation strap needs to be re-secured, which is not only time-consuming, but also may cause the catheter to fall out of the body during the operation.
[0005] Based on this, the present invention designs an adjustable catheter fixation device to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable catheter fixation device.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 An adjustable catheter fixation device includes a support and fixation mechanism 1 and a catheter limiting component 2;
[0030] One end of the support and fixing mechanism 1 is equipped with a catheter limiting component 2;
[0031] The support and fixation mechanism 1 includes a support bar 11, a skin-friendly pad 12, a fastening component, and a limiting wheel 15; the fastening component is installed on the support bar 11, the outer wall of the support bar 11 is evenly and uniformly fixedly connected to multiple skin-friendly pads 12, the inner end of the support bar 11 is rotatably connected to multiple limiting wheels 15, and an inlet / outlet hole 16 is opened at the connection between the support bar 11 and the catheter limiting component 2.
[0032] The support bar 11 is made of elastic material, and both ends of the support bar 11 always tend to close automatically, wrapping around the patient's leg. The cross-section of the support bar 11 is U-shaped.
[0033] The fastening assembly includes a fixing strap 13 and a hook and loop fastener 14; the two ends of the support strip 11 are fixedly connected to the two fixing straps 13 respectively, and the hook and loop fastener 14 is divided into a rough side and a barbed side, which are fixedly connected to the two fixing straps 13 respectively, and the rough side and the barbed side of the hook and loop fastener 14 are adhered to each other.
[0034] In this invention, a urinary catheter is placed between the support bar 11 and the limiting wheel 15. The limiting wheel 15 restricts the urinary catheter and reduces the friction when the urinary catheter moves inside the support bar 11. One end of the urinary catheter is connected to the urine bag, and the other end extends from one side of the support bar 11, passes through the inlet / outlet hole 16 and enters the urinary catheter limiting component 2, and then continues to extend until it is connected to the genitals. The urinary catheter limiting component 2 restricts the urinary catheter, so that the urinary catheter can only be stretched forward in one direction. Then the support bar 11 is placed on the human leg, and the fixing strap 13 and the support bar 11 are fixed in the appropriate position on the human leg by Velcro 14 at different positions.
[0035] In this invention, the urinary catheter is better secured to the leg by the support bar 11, the fixing strap 13 and the Velcro 14. The urinary catheter limiting component 2 ensures that the urinary catheter can only be stretched forward in one direction. While adjusting the condition of the urinary catheter, it prevents the urinary catheter from accidentally falling off due to force on one side. The excess urinary catheter is placed inside the support bar 11 under the restriction of the limiting wheel 15 for the purpose of constriction and storage of the urinary catheter.
[0036] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the catheter limiting assembly 2 includes a pre-limiting assembly 21 and a one-way limiting assembly 22; the one-way limiting assembly 22 is installed inside the pre-limiting assembly 21.
[0037] The pre-limiting component 21 includes an opening and closing plate 211, a fixing plate 212, and a fixing component 213; one end of the support bar 11 is fixedly connected to the fixing plate 212, the opening and closing plate 211 is aligned on the upper side of the fixing plate 212, one end of the fixing plate 212 and the opening and closing plate 211 are hinged, and the other end of the fixing plate 212 and the opening and closing plate 211 is provided with a fixing component 213 for controlling whether the fixing plate 212 and the opening and closing plate 211 are locked;
[0038] The fixing component 213 includes a buckle 2131; the other end of the opening and closing plate 211 is fixedly connected to the buckle 2131, and the other end of the fixing plate 212 is provided with a slot 2132 that engages with the buckle 2131.
[0039] The one-way limiting component 22 includes a base 221, a spring 222, a locking block 223, and a connecting plate 224. Two bases 221 are symmetrically arranged on the inner sides of the opening and closing plate 211 and the fixing plate 212, and are fixedly connected to the opening and closing plate 211 and the fixing plate 212 respectively. One end of the connecting plate 224 is fixedly connected to the rear end of the base 221, and the other end of the connecting plate 224 is rotatably connected to the rear end of the locking block 223 through a bearing. The front end of the base 221 and the front end of the locking block 223 are fixedly connected to both ends of the spring 222 respectively.
[0040] In this invention, the urinary catheter passes through the inlet / outlet hole 16 and enters the urinary catheter limiting assembly 2. After being stretched to a suitable length, it is connected to the genitals. When the urinary catheter enters the fixing plate 212, the opening and closing plate 211 is closed, and the buckle 2131 and the slot 2132 are engaged, initially limiting the urinary catheter. At this time, the urinary catheter contacts the front end of the locking block 223. When the urinary catheter is stretched forward, the front end of the locking block 223 is subjected to frictional force and moves with the bearing as the fixed point, causing the spring 222 to contract and deform. After the urinary catheter stops stretching, it returns to its original position. When the urinary catheter is stretched backward, the front end of the locking block 223 is subjected to frictional force and moves with the bearing as the fixed point, causing the spring 222 to extend and deform. The upper and lower locking blocks 223 limit the urinary catheter and prevent the urinary catheter from being stretched backward.
[0041] In this invention, the interaction between the upper and lower locking blocks 223 and the catheter adjusts the catheter's position, ensuring that the catheter can only be stretched forward in one direction. This prevents the catheter from accidentally dislodging due to force on one side of the urine bag, thus reducing the risk of catheter dislodgement.
[0042] The skin-friendly pad 12 is in direct contact with the patient's skin, and multiple ventilation holes are evenly arranged on the skin-friendly pad 12 for heat dissipation from the patient's skin.
[0043] In its natural state, the spring 222 keeps the locking block 223 tilted. When the catheter is stretched, only the front end of the locking block 223 is subjected to force, which better limits the catheter.
[0044] The buckle 2131 is U-shaped and protrudes from the opening and closing plate 211. The slot 2132 is T-shaped. The snap-fit end of the buckle 2131 is elastic and is used to enter the slot 2132 and snap-fit with it. When the snap-fit end is snap-fit with the slot 2132, the operator pinches the snap-fit end of the buckle 2131 to deform it and better align it with the slot 2132. When it is necessary to end the snap-fit, the operator pinches the protruding part of the snap-fit end of the buckle 2131 to deform it. At this time, the buckle 2131 and the slot 2132 have no snap-fit function.
[0045] 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 of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
