Abstract
Description
Technical Field
[0001] This invention relates to the technical field of urinary catheters, and more particularly to an adjustable urinary catheter fixation bracket. Background Technology
[0002] In the field of medical care, for patients who need to use urinary catheters for a long period or temporarily, ensuring that the urinary catheter and its connected urine collection bag are securely and comfortably fixed is not only key to improving the patient's quality of life, but also an important measure to reduce complications.
[0003] Traditional fixation methods rely on medical tape to directly attach the urine collection bag to the skin surface. While this method is simple and easy to implement, it does have some significant problems in practical applications. For example, due to the influence of daily activities (such as walking and turning over), the catheter, which is only fixed by tape, is easily pulled downward by the weight of the urine inside the collection bag, causing displacement. This displacement causes repeated pulling and friction between the catheter and the skin, which may not only lead to poor drainage but also cause friction damage to the skin, resulting in uncomfortable pain. Furthermore, frequent friction may damage the skin barrier function, making it easier for bacteria and other pathogens to invade, leading to local inflammation and increasing the risk of urinary tract infections. Summary of the Invention
[0004] To overcome the drawback of urinary catheters being prone to displacement due to the weight of urine in the collection bag, this invention provides an adjustable urinary catheter fixation bracket.
[0005] An adjustable catheter fixation bracket includes a fixing belt, a first fixing block fixedly connected to the fixing belt, a rotating frame rotatably connected to the first fixing block, a guide tube rotatably connected to the first fixing block, a connecting frame splined to the guide tube, the rotating frame and the connecting frame engaging at their proximal ends, a spring fixedly connected between the first fixing block and the guide tube, a spring wound around the connecting frame, one end of the spring contacting the first fixing block, a connecting strap wound around the rotating frame, a rotating plate fixedly connected to the end of the connecting strap away from the first fixing block, and a bandage fixedly connected to the rotating plate.
[0006] Optionally, both the waist belt and the bandage are secured with Velcro.
[0007] Optionally, it also includes a rotating rod, which is rotatably connected to the first fixed block. A rotating block is fixedly connected to the rotating rod, and a first torsion spring is fixedly connected between the rotating block and the first fixed block. A friction block is fixedly connected to the side of the rotating frame near the rotating block. When the rotating block swings, it contacts the friction block and engages in frictional contact.
[0008] Optionally, it also includes an impact frame, which is rotatably connected to the side of the first fixed block near the connecting frame. The first fixed block is fixed with a metal plate, the impact frame contacts the metal plate, and a second torsion spring is fixed between the impact frame and the first fixed block.
[0009] Optionally, the connecting frame has a convex surface on the side near the impact frame, and the connecting frame is pressed and engaged with the impact frame through the convex surface.
[0010] Optionally, the side of the impact frame closest to the convex surface is configured as an outwardly protruding hook.
[0011] Optionally, it also includes a second fixing block symmetrically distributed along the rotating plate. The second fixing block is fixedly connected to the rotating plate and is rotatably connected to an elastic latch. The second fixing block and the latch on it engage with each other.
[0012] Optionally, it also includes a rubber pad corresponding to the buckle, the rubber pad being fixed to the corresponding buckle for securing the urine collection bag.
[0013] Optionally, the fixing belt has a storage cavity for storing a spare urine collection bag.
[0014] Optionally, it also includes a cover plate, which is rotatably connected to the side of the fixing belt near the storage cavity, and magnets that attract each other are fixed to both the fixing belt and the cover plate.
[0015] The beneficial effects are: This invention utilizes the strength of the waist to lift and counteract the weight of the urine collection bag through the connecting strap, and prevents the rotating frame from rotating indefinitely through the torque of the spring, thereby preventing the connecting strap from loosening and making the catheter less likely to be pulled downward by the weight of the urine in the urine collection bag, thus avoiding the negative impact on the patient caused by catheter displacement.
[0016] This invention uses the snap-fit mechanism between the rotating frame and the connecting frame to allow the connecting belt to be freely and adaptively cut to the corresponding length before the fixing belt is tied on, so as to accommodate patients of different heights. After the fixing belt is tied on, it is restricted by the spring and can only perform limited movements. It cannot move freely at all, nor is it completely fixed. Thus, it can ensure a certain degree of lifting while taking into account the patient's normal daily activities of walking.
[0017] This invention utilizes the swinging block to contact the friction block during the patient's dynamic activities, making the rotating frame more difficult to rotate and thus making the connecting belt more difficult to pull downwards. When the patient is in a static state such as lying down or sitting, the rotating block disengages from the friction block, and the connecting belt is only restricted by the spring, allowing the patient to move their legs and feet relatively easily in a static state.
[0018] This invention uses an impact frame to strike a metal plate, thereby producing an impact sound to remind the patient that the urine collection bag is moving downwards, and that the patient should be careful not to move too much or whether the urine collection bag needs to be replaced.
[0019] This invention uses rubber pads on the buckle to press the corners of the urine collection bag tightly, thus eliminating the need to use additional tape to stick the urine collection bag to the rotating plate.
[0020] This invention utilizes a storage cavity to store an empty urine collection bag, making it convenient for patients to change the urine collection bag in a timely manner. Attached Figure Description

Detailed Implementation
[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.
[0032] Example 1: An adjustable catheter fixation bracket, such as Figures 1-4 As shown, the device includes a fixed waist belt 101, with both ends of the fixed waist belt 101 glued together with Velcro. A first fixing block 102 is fixed to the front side of the fixed waist belt 101. A rotating frame 103 is rotatably connected to the first fixing block 102. A guide tube 105 is rotatably connected to the right side of the first fixing block 102. A connecting frame 104 is splined along the left and right direction inside the guide tube 105. The ends of the rotating frame 103 and the connecting frame 104 are engaged with each other. A spring 106 is fixed between the first fixing block 102 and the guide tube 105. A spring 107 is wound around the connecting frame 104. The right end of the spring 107 contacts the first fixing block 102. A connecting strap 108 is wound around the middle of the rotating frame 103. A rotating plate 109 is fixed to the end of the connecting strap 108 away from the first fixing block 102. A hinge shaft is provided in the middle of the rotating plate 109. A bandage 110 is fixed between the two sides of the rotating plate 109. The two ends of the bandage 110 are glued together with Velcro.
[0033] In use, first use tape to attach the urine collection bag to the freely rotating plate 109, then tie the bandage 110 around the patient's leg. Next, pull the connecting frame 104 to the right, causing it to slide along the guide tube 105 to the right until it disengages from the right end of the rotating frame 103, compressing the spring 107. Then, pull the fixing belt 101 upwards to the patient's waist. During the upward pull, the connecting strap 108 is adaptively stretched to the corresponding length. Finally, release the connecting frame 104, allowing it to... Under the action of spring 107, it slides to the left until it locks the rotating frame 103, and then the fixing belt 101 is tied around the patient's waist. In this way, the present invention uses the strength of the waist to lift against the weight of the urine collection bag through the connecting belt 108, and prevents the rotating frame 103 from rotating indefinitely by the torque of the spring 106, thereby preventing the connecting belt 108 from loosening at will. This makes the catheter less likely to be pulled downward by the weight of the urine in the urine collection bag, so as to avoid the negative impact on the patient caused by the displacement of the catheter.
[0034] Moreover, the present invention allows the connecting belt 108 to be freely and adaptively adjusted to the corresponding length before the fixing belt 101 is tied on, so as to accommodate patients of different heights. After the fixing belt 101 is tied on, it can only perform limited movements due to the restriction of the spring 106. It cannot move freely or be completely fixed, thus ensuring a certain degree of lifting while taking into account the patient's normal daily activities of walking.
[0035] Example 2: Based on Example 1, as follows Figure 2 and Figure 5As shown, it also includes a rotating rod 201, which is rotatably connected to the first fixed block 102. A rotating block 202 is fixedly connected to the rotating rod 201. A first torsion spring 203 is fixedly connected between the rotating block 202 and the first fixed block 102. A friction block 204 is fixedly connected to the left side of the rotating frame 103. When the rotating block 202 swings up and down, it contacts and rubs against the friction block 204.
[0036] The patient is prone to pulling on the urinary catheter during dynamic activities such as walking. Therefore, in addition to the restriction provided by the spring 106, the following measures are taken to further strengthen the restriction on the connecting strap 108 when the patient is walking:
[0037] When the patient walks, the rotating block 202 swings up and down until it contacts the friction block 204 due to the influence of the body's movement. The first torsion spring 203 deforms adaptively. Due to the friction between the rotating block 202 and the friction block 204, the rotating frame 103 is more difficult to rotate, and the connecting belt 108 is more difficult to be pulled down. When the patient is in a static state such as lying down or sitting, the first torsion spring 203 is in a natural state, the rotating block 202 is disengaged from the friction block 204, and the connecting belt 108 is only restricted by the spring 106, which makes it easier for the patient to move their legs and feet relatively easily in a static state.
[0038] like Figure 2 , Figure 5 and Figure 6 As shown, it also includes an impact frame 302, which is rotatably connected to the right side of the first fixed block 102. A convex surface 301 is provided on the side of the connecting frame 104 near the impact frame 302. The connecting frame 104 is pressed and engaged with the impact frame 302 through the convex surface 301. The side of the impact frame 302 near the convex surface 301 is configured as an outwardly protruding hook shape. A metal sheet 303 is fixedly connected to the upper right side of the first fixed block 102. The impact frame 302 contacts the metal sheet 303. A second torsion spring 304 is fixedly connected between the impact frame 302 and the first fixed block 102.
[0039] The connecting frame 104 rotates, causing the convex surface 301 to rotate. The connecting frame 104, through the convex surface 301, squeezes the impact frame 302 to rotate until it separates from the metal plate 303. The second torsion spring 304 deforms. When the impact frame 302 rotates to separate from the convex surface 301, the second torsion spring 304 resets, causing the impact frame 302 to rotate in the opposite direction until it contacts the metal plate 303, making an impact sound to remind the patient that the urine collection bag is moving downwards. The patient should pay attention to the fact that the range of motion should not be too large or whether the urine collection bag needs to be replaced.
[0040] Example 3: Based on Example 2, such as Figure 7 and Figure 8As shown, it also includes eight second fixing blocks 401 symmetrically distributed along the left and right sides of the rotating plate 109. The second fixing blocks 401 are fixedly connected to the rotating plate 109. The second fixing blocks 401 are rotatably connected to the elastic buckles 402. The second fixing blocks 401 and the buckles 402 on them engage with each other. The buckles 402 are fixedly connected to the rubber pads 403 for fastening the urine collection bag.
[0041] Before fixing the urine collection bag onto the rotating plate 109, first turn upwards to open all the latches 402, then place the urine collection bag between each latch 402, and then turn downwards to close the latches 402, so that the rubber pads 403 press against the corners of the urine collection bag. In this way, there is no need to use additional tape to stick the urine collection bag onto the rotating plate 109.
[0042] like Figure 7 and Figure 9 As shown, it also includes a cover plate 502, and a storage cavity 501 for storing spare urine collection bags is opened in the fixed waist belt 101. The cover plate 502 is rotatably connected to the side of the fixed waist belt 101 near the storage cavity 501. Magnets 503 that attract each other are fixedly attached to both the fixed waist belt 101 and the cover plate 502.
[0043] Open the cover 502, stack multiple empty spare urine collection bags in the storage chamber 501, then close the cover 502 and fix the cover 502 to the fixing belt 101 by magnet 503.
