Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a circumferential guide rail for peritoneal dialysis. Background Technology
[0002] Peritoneal dialysis uses the body's own peritoneum as a dialysis membrane. During dialysis, a certain concentration of peritoneal dialysis fluid is placed into the abdominal cavity. After being filtered by the peritoneum, excess metabolic products and water are drained out of the body to maintain water and electrolyte balance and achieve the purpose of replacing the work of the kidneys. It is one of the important replacement therapies for patients with end-stage renal disease.
[0003] The patient requires long-term peritoneal dialysis treatment. Currently, there are no dedicated nursing beds for peritoneal dialysis patients. Therefore, dialysis is performed on ordinary hospital beds or nursing beds.
[0004] Before performing peritoneal dialysis, the peritoneal dialysis fluid needs to be removed from the incubator.
[0005] During treatment, some patients, lacking a designated place to store their drainage bags, place them directly on the ground, or even temporarily store plastic buckets or boxes under the bed on the floor.
[0006] Different patients require different positions during peritoneal dialysis, as instructed by medical staff. For each position, there are specific requirements for the placement of the drainage bag to prevent the dialysis tubing from being misplaced, bent, or accidentally pulled, which could affect the dialysis effect. Utility Model Content
[0007] The purpose of this invention is to provide a circumferential guide rail for peritoneal dialysis, so as to solve the technical problem that ordinary hospital beds cannot properly place drainage bags according to the patient's position during dialysis in the existing technology.
[0008] To solve the above-mentioned technical problems, this utility model specifically provides a circumferential guide rail for peritoneal dialysis, including a movable pad and an annular track set on the movable pad. The annular track is elliptical and its major axis is aligned with the direction of the bed. A storage box for placing drainage bags is slidably installed on the annular track.
[0009] The circular track is arranged in a ring around the edge of the movable pad to match the hospital bed, and the storage box slides along the circular track to any position to accommodate patients in different positions.
[0010] Furthermore, the cross-section of the annular track is convex in shape;
[0011] The storage box is connected to an inverted U-shaped slider via a pivot. The slider wraps around the annular track and slides in contact with the annular track.
[0012] Furthermore, the slider includes a connecting plate rotatably connected to the rotating shaft, and the connecting plate is in contact with the top surface of the annular track;
[0013] Rotary rollers that fit against the sides of the annular track are rotatably connected to both ends of the connecting plate. The rollers located on both sides of the annular track clamp the annular track to fix the storage box on the annular track.
[0014] Furthermore, a rotating shaft is provided at both ends of the storage box.
[0015] Furthermore, an elastic element is fixedly installed on the top side of the annular track to limit the slider;
[0016] The elastic element is specifically a teardrop-shaped protrusion of elastic material.
[0017] Compared with the prior art, this utility model has the following advantages:
[0018] In this invention, during peritoneal dialysis, one end of the dialysis catheter is connected to the patient's abdomen, and the other end is connected to the drainage bag in the storage box. The convex-shaped annular track forms a surrounding space on the bed, allowing the storage box to slide to any position to accommodate patients in different positions without affecting the patient's rest. This ensures that the dialysis catheter is placed in an orderly manner and does not restrict the patient's movement. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1 to 3 As shown, this utility model specifically provides a circumferential guide rail for peritoneal dialysis, including a movable pad 1, an annular track 2 disposed below the movable pad 1, and a storage box 3 for placing drainage bags slidably mounted on the annular track 2.
[0027] In this embodiment, there are two implementations based on whether or not a movable pad is present.
[0028] Example 1:
[0029] Includes a movable pad 1, and a circular track 2 installed on the movable pad 1.
[0030] Example 2:
[0031] Excluding the movable pad 1, the circular track 2 is placed directly on the ordinary hospital bed.
[0032] In practical applications, Example 1 is generally chosen. It should be further explained here that the circular track 2 can be as follows: Figure 1 The closed loop shown can also be a non-closed structure with the head and foot sections of the bed separated, depending on the actual needs.
[0033] When it is a closed ring structure, the ring track 2 is elliptical, and its major axis is aligned with the direction of the bed. Its major axis needs to be as long as possible so that the patient can lie inside the ellipse. In this case, the ring track 2 forms a surrounding space, and only one sliding box 3 is needed.
[0034] When it is a non-closed ring structure, the ring track 2 cannot form a closed structure. In this case, two slide boxes 3 are needed, located on the ring track 2 on both sides respectively.
[0035] Since there are many embodiments of this utility model, this embodiment is described using a movable pad 1 and a closed ring structure for the annular track 2. However, it is not excluded that other embodiments may be selected according to specific needs.
[0036] The circular track 2 surrounds the inner edge of the movable pad 1, and the storage box 3 can move along the circular track 2 to any position on the edge of the movable pad 1 to accommodate patients in any position.
[0037] During peritoneal dialysis, one end of the dialysis tubing is connected to the patient's abdomen, and the other end is connected to the drainage bag inside the storage slide 3, which is located on the annular track 2 at the bottom of the movable pad 1.
[0038] The storage box 3 can slide along the circular track 2 to any position on the edge of the movable pad 1, preventing the dialysis tubing from being pulled when the patient moves. That is, the position of the storage box 3 can be adjusted according to the patient's position. When the patient is on the left side of the movable pad 1, the storage box 3 can be moved along the circular track 2 to the left side of the movable pad 1.
[0039] It should be noted that when moving the storage slide box 3, the drainage bag needs to be removed from the storage slide box 3. After moving the storage slide box 3 to the designated position, the drainage bag is then placed back into the storage slide box 3 (in this utility model). Figure 1 In the image, the storage slide 3 shown is only a single location and is not a storage slide 3 of actual scale.
[0040] Furthermore, the cross-section of the annular track 2 is convex in shape;
[0041] The storage box 3 is connected to an inverted U-shaped slider 4 via a rotating shaft 7. The slider 4 wraps around the annular track 2 and slides in contact with the annular track 2.
[0042] With the circular track 2 set as an ellipse, in order to enable the sliders 4 located on the front and rear sides of the storage box 3 to slide smoothly on the circular track 2, the slider 4 includes a connecting plate 5 rotatably connected to the rotating shaft 7, and the connecting plate 5 is in contact with the top surface of the circular track 2.
[0043] Rotating rollers 6, which fit against the sides of the annular track 2, are rotatably connected to both ends of the connecting plate 5. The rotating rollers 6 on both sides of the annular track 2 clamp the annular track 2 to fix the storage box 3 on the annular track 2. The storage box 3 is rotatably connected to the connecting plate 5 via a rotating shaft 7. During the movement of the storage box 3, the connecting plate 5 can adaptively deflect according to the curvature of the ellipse.
[0044] The connecting plate 5 mainly bears the weight of the storage box 3 and the liquid bag. The rollers 6 on both sides of the connecting plate 5 are used to constrain and fix the storage box 3 on the annular track 2 and reduce the frictional resistance of the storage box 3 when it moves.
[0045] To improve the stability of the storage box 3 on the circular track 2, such as Figure 3As shown, a rotating shaft 7 is provided at both ends of the storage box 3, and two sliders 4 are installed through the two rotating shafts 7.
[0046] In addition, an elastic element is fixedly installed on the top side of the annular track 2 to limit the slider 4. The elastic element is specifically a teardrop-shaped protrusion of elastic material.
[0047] When needed, simply press the slider 4 down firmly to lock it onto the circular track 2 so it won't easily fall off. When not needed, simply pull it up firmly to disassemble it.
[0048] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
