Description

Technical Field

[0001] The present invention relates to the technical field of urinary catheters, and in particular to an adjustable urinary catheter fixing bracket. Background Art

[0002] In the field of medical care, for patients who need long-term or temporary use of a urinary catheter, ensuring that the catheter and its connected urine collection bag are securely and comfortably fixed is not only the key to improving the patient's quality of life, but also an important measure to reduce complications.

[0003] The traditional fixation method relies on using medical tape to directly stick the urine collection bag to the skin surface. Although this method is simple and easy, it does have some significant problems in actual application. For example, due to the influence of daily activities (such as walking and turning over), the catheter fixed solely by tape is easily pulled downward by the weight of the urine in the urine collection bag, thereby shifting. This displacement will cause 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, causing uncomfortable pain. The skin barrier function may also be destroyed due to frequent friction, making it easier for bacteria and other pathogens to invade, thereby leading to local inflammation and increasing the risk of urinary tract infection. Summary of the Invention

[0004] In order to overcome the disadvantage that a urinary catheter is easily displaced by the weight of urine in a urine collection bag, the present invention provides an adjustable urinary catheter fixing bracket.

[0005] An adjustable urinary catheter fixing bracket includes a fixing belt, which is fixedly connected to a first fixing block, which is rotatably connected to a rotating frame, which is rotatably connected to a guide tube, which is splined to a connecting frame, and the ends of the rotating frame and the connecting frame that are close to each other are engaged with each other, a clockwork is fixedly connected between the first fixing block and the guide tube, a spring is wound on the connecting frame, one end of the spring is in contact with the first fixing block, a connecting belt is wound on the rotating frame, an end of the connecting belt away from the first fixing block is fixedly connected to a rotating plate, and the rotating plate is fixedly connected to a bandage.

[0006] Optionally, both the fixing belt and the bandage are attached by Velcro.

[0007] Optionally, it also includes a rotating rod, which is rotatably connected to the first fixed block, the rotating rod is fixed with a rotating block, a first torsion spring is fixed between the rotating block and the first fixed block, and a friction block is fixed on the side of the rotating frame close to the rotating block. When the rotating block swings, it contacts and frictionally engages with the friction block.

[0008] Optionally, a collision frame is further included, which is rotatably connected to the side of the first fixed block close to the connecting frame. The first fixed block is fixed with a metal sheet, the collision frame is in contact with the metal sheet, and a second torsion spring is fixed between the collision frame and the first fixed block.

[0009] Optionally, a convex surface is provided on a side of the connecting frame close to the impact frame, and the connecting frame is extruded and fitted with the impact frame through the convex surface.

[0010] Optionally, a side of the impact frame close to the convex surface is configured to be in an outwardly protruding hook shape.

[0011] Optionally, it further includes a second fixing block symmetrically distributed along the rotating plate, the second fixing block is fixedly connected to the rotating plate, the second fixing block is rotatably connected to an elastic lock, and the second fixing block and the lock thereon are engaged with each other.

[0012] Optionally, a rubber pad corresponding to the lock buckle is further included, and the rubber pad is fixedly connected to the corresponding lock buckle for fastening the urine collection bag.

[0013] Optionally, a storage cavity for storing a spare urine collection bag is opened in the fixed waist belt.

[0014] Optionally, a cover plate is further included, which is rotatably connected to a side of the fixed waist belt close to the storage cavity, and the fixed waist belt and the cover plate are both fixed with magnets that attract each other.

[0015] The beneficial effect is that the present invention utilizes the strength of the waist to pull the connecting belt against the weight of the urine collection bag, and prevents the rotating frame from rotating infinitely by the torsional action of the spring, thereby preventing the connecting belt from loosening at will, making it difficult for the urinary catheter to be pulled downward by the weight of the urine in the urine collection bag, thereby avoiding the negative impact of the displacement of the urinary catheter on the patient.

[0016] The present invention uses a snap-fit ​​connection between the rotating frame and the connecting frame so that the connecting belt can be freely and adaptively adjusted to a corresponding length before the fixed belt is fastened to accommodate patients of different heights. After the fixed belt is fastened, the connecting belt is restricted by the spring and can only move to a limited extent. It is neither completely free to move nor completely fixed. This ensures a certain degree of lifting while taking into account the patient's normal walking daily activities.

[0017] The present invention utilizes the rotating block to swing until the friction block contacts and rubs when the patient is in dynamic activities, making it more difficult for the rotating frame to rotate, thereby making it more difficult for the connecting belt to be pulled downward. When the patient is in a static state such as lying down or sitting quietly, the rotating block is disengaged from the friction block, and the connecting belt is only restricted by the spring, making it convenient for the patient to move his legs and feet relatively easily in a static state.

[0018] The present invention uses the impact frame to impact the metal sheet, thereby generating an impact sound, reminding the patient that the urine collection bag is moving down, and that the patient should be careful not to move too much or whether the urine collection bag needs to be replaced.

[0019] The present invention compresses the corners of the urine collecting bag by means of the rubber pads on the lock buckle, thus eliminating the need to use additional adhesive tape to stick the urine collecting bag to the rotating plate.

[0020] The present invention utilizes the storage cavity to store an empty urine collection bag, so that the patient can replace the urine collection bag in time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0032] Example 1: An adjustable urinary catheter fixing bracket, such as Figures 1-4 As shown, it includes a fixed belt 101, the two ends of the fixed belt 101 are bonded by Velcro, and the front side of the fixed belt 101 is fixedly connected to a first fixed block 102, and the first fixed block 102 is rotatably connected to a rotating frame 103, and the right side of the first fixed block 102 is rotatably connected to a guide tube 105, and the guide tube 105 is splined with a connecting frame 104 along the left and right directions. A spring 106 is fixed between the first fixed block 102 and the guide tube 105, and a spring 107 is wound on the connecting frame 104. The right end of the spring 107 contacts the first fixed block 102, and a connecting belt 108 is wound around the middle of the rotating frame 103. The end of the connecting belt 108 away from the first fixed block 102 is fixedly connected to a rotating plate 109, and 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, and the two ends of the bandage 110 are bonded by Velcro.

[0033] When in use, first use tape to stick the urine collection bag to the freely rotatable rotating plate 109, then tie the bandage 110 to the patient's leg, and then pull the connecting frame 104 to the right, so that the connecting frame 104 slides to the right along the guide tube 105 until it is separated from the right end of the rotating frame 103, and the spring 107 is compressed. Then, pull the fixed belt 101 upward to the patient's waist. During the upward pulling process, the connecting belt 108 is adaptively pulled out to the corresponding length, and then loosen the connecting frame 104 so that the connecting frame 104 is Under the action of the spring 107, it slides to the left until it catches the rotating frame 103, and then the fixed belt 101 is tied around the patient's waist. In this way, the present invention uses the strength of the waist to pull the connecting belt 108 to resist the weight of the urine collection bag, and through the torsional action of the spring 106, it prevents the rotating frame 103 from rotating indefinitely, thereby preventing the connecting belt 108 from loosening at will, making it difficult for the urinary catheter 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 urinary catheter.

[0034] Moreover, the present invention uses the snap-fit ​​connection between the rotating frame 103 and the connecting frame 104 so that the connecting belt 108 can be freely and adaptively adjusted to a corresponding length before the fixed belt 101 is fastened to accommodate patients of different heights. After the fixed belt 101 is fastened, it is restricted by the spring 106 and can only move to a limited extent. It cannot move completely freely, nor is it completely fixed. This ensures a certain degree of lifting while taking into account the patient's normal walking daily activities.

[0035] Example 2: Based on Example 1, 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 fixed to the rotating rod 201, and a first torsion spring 203 is fixed between the rotating block 202 and the first fixed block 102. A friction block 204 is fixed to the left side of the rotating frame 103. When the rotating block 202 swings up and down, it contacts and frictionally cooperates with the friction block 204.

[0036] Patients are most likely to pull on the catheter during dynamic activities such as walking. Therefore, in order to further strengthen the restriction of the connecting belt 108 when the patient walks, the specific operation is as follows:

[0037] When the patient walks, affected by human body movements, the rotating block 202 will swing up and down until it contacts the friction block 204, and the first torsion spring 203 will adaptively deform. Due to the friction between the rotating block 202 and the friction block 204, the rotating frame 103 is more difficult to rotate, and thus the connecting belt 108 is more difficult to be pulled downward. When the patient is in a static state such as lying down or sitting quietly, 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 convenient for the patient to move his 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, and a convex surface 301 is provided on the side of the connecting frame 104 close to the impact frame 302. The connecting frame 104 is squeezed and matched with the impact frame 302 through the convex surface 301. The side of the impact frame 302 close to the convex surface 301 is set to a hook protruding outward, and a metal sheet 303 is fixed to the upper right part of the first fixed block 102. The impact frame 302 is in contact with the metal sheet 303, and a second torsion spring 304 is fixed between the impact frame 302 and the first fixed block 102.

[0039] The rotation of the connecting frame 104 drives the convex surface 301 to rotate. The connecting frame 104 squeezes the impact frame 302 through the convex surface 301 and rotates to separate from the metal sheet 303. The second torsion spring 304 is deformed. When the impact frame 302 rotates to separate from the convex surface 301, the second torsion spring 304 resets and drives the impact frame 302 to rotate in the opposite direction until it contacts the metal sheet 303, making a knocking sound, reminding the patient that the urine collection bag is moving down, and attention should be paid to whether the movement range is too large or whether the urine collection bag needs to be replaced.

[0040] Example 3: Based on Example 2, Figure 7 and Figure 8As shown, it also includes second fixing blocks 401 symmetrically distributed along the rotating plate 109. There are eight second fixing blocks 401 in total. The second fixing blocks 401 are fixedly connected to the rotating plate 109. An elastic lock 402 is rotatably connected to the second fixing blocks 401. The second fixing blocks 401 and the lock 402 thereon are engaged with each other. A rubber pad 403 for fastening the urine collection bag is fixed to the lock 402.

[0041] Before fixing the urine collection bag on the rotating plate 109, first rotate all the lock buckles 402 upward to open them, then place the urine collection bag between the lock buckles 402, and then rotate the lock buckles 402 downward to close them, so that the rubber pads 403 press the corners of the urine collection bag tightly. In this way, there is no need to use additional tape to stick the urine collection bag to the rotating plate 109.

[0042] like Figure 7 and Figure 9 As shown, a cover plate 502 is also included. A storage cavity 501 for storing a spare urine collection bag is opened in the fixed belt 101. The cover plate 502 is rotatably connected to a side of the fixed belt 101 close to the storage cavity 501. Magnets 503 that attract each other are fixed to the fixed belt 101 and the cover plate 502.

[0043] Open the cover 502 , stack a plurality of empty spare urine collection bags in the storage chamber 501 , then close the cover 502 and fix the cover 502 to the fixed waist belt 101 via the magnet 503 .
