Description

Technical Field

[0001] The utility model relates to the technical field of peritoneal dialysis, in particular to a limb fixing device for peritoneal dialysis. Background Art

[0002] Peritoneal dialysis is one of the main alternative treatments for patients with uremia. Peritoneal dialysis uses the peritoneum as a semipermeable membrane. The peritoneal dialysis fluid is introduced through a catheter pre-buried in the patient's abdomen and retained for 3-4 hours. The peritoneal dialysis fluid is then led out by the catheter. The osmotic difference helps the patient excrete excess water and metabolic waste from the body to complete the dialysis process. Peritoneal dialysis needs to be performed every day to maintain a stable and normal internal environment in the patient. As a home treatment method, peritoneal dialysis has many unique advantages. Now, during peritoneal dialysis, the patient's limbs need to be stabilized to prevent the body from shaking, which will affect the peritoneal dialysis treatment.

[0003] The cam is configured to move the legs and the legs together so that the legs can be moved in a controlled manner and the two legs can be adjusted accordingly.

[0004] Although the above solution solves the problems mentioned in the background technology, it still has the following shortcomings: when the limbs are clamped by the left and right clamping plates, the skin at the bottom of the limbs can easily be squeezed by the clamping structure when the clamping structure moves, causing pain and other discomfort to the patient, reducing the patient's usage experience. Utility Model Content

[0005] The purpose of the utility model is to provide a limb fixing device for peritoneal dialysis to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] As a preferred solution of the utility model, a thread groove structure corresponding to the thread structure on the outer side of the threaded rod is provided on the inner side of the threaded sleeve, and the threads on the left and right ends of the threaded rod are in opposite directions. The left and right threaded sleeves are correspondingly rotatably connected to the outer left and right ends of the threaded rod.

[0009] As a preferred solution of the utility model, the jackets at the left and right ends are both arc-shaped structures, the left and right ends are left-right symmetrical structures, and the bottoms are correspondingly installed on the tops of the movable seats at the left and right ends.

[0010] As a preferred solution of the utility model, the elastic pads at the left and right ends are connected to the inner side of the jacket at a side away from the placement seat.

[0011] As a preferred solution of the utility model, the placement seat is an overhead structure, and the inside of the placement seat has a space that passes through from left to right.

[0012] As a preferred solution of the utility model, the width of the jacket is slightly smaller than the internal width of the placement seat, and the bottoms of the left and right jackets are movably placed inside the placement seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, a limb fixing device for peritoneal dialysis is provided, and the jacket and the placement seat structure in the device are utilized to separate the bottom of the limb from the jacket, and can prevent the jacket from accidentally getting caught on the patient's skin during movement, thereby causing harm to the patient, thereby solving the problem of causing discomfort such as pain to the patient and reducing the patient's use experience.

[0023] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0024] A limb fixing device for peritoneal dialysis, comprising two groups of front and rear fixing seats 1, wherein a threaded rod 2 is installed inside each fixing seat 1, a knob 3 is installed at the left end of the threaded rod 2, a threaded sleeve 4 is connected to the outside of the threaded rod 2, a movable seat 5 is connected to the top of the threaded sleeve 4, a clamping sleeve 6 is installed on the top of the movable seat 5, a placement seat 7 is installed at the bottom of the fixing seat 1, a sponge pad 8 is installed on the top of the placement seat 7, elastic pads 9 are installed on the left and right sides of the placement seat 7, and a connecting rod 10 is installed between the front and rear fixing seats 1;

[0025] Specifically, a thread groove structure corresponding to the thread structure on the outer side of the threaded rod 2 is provided on the inner side of the threaded sleeve 4, and the threads on the left and right ends of the threaded rod 2 are provided in opposite directions, and the left and right end threaded sleeves 4 are correspondingly rotatably connected to the left and right ends of the outer side of the threaded rod 2;

[0026] In this embodiment, the threaded sleeve 4 on the surface of the threaded rod 2 can be operated by the rotation of the threaded rod 2 to facilitate left and right movement.

[0027] Specifically, the left and right end jackets 6 are both arc-shaped structures, and the left and right ends are left-right symmetrical structures, and the bottoms are correspondingly installed on the tops of the left and right end movable seats 5;

[0028] In this embodiment, the jacket 6 can stably follow the movement of the movable seat 5 to move.

[0029] Specifically, the left and right elastic pads 9 are connected to the inner side of the jacket 6 at a side away from the placement seat 7;

[0030] In this embodiment, the other end of the elastic pad 9 will stretch along with the position of the movable seat 5, so as to conveniently isolate the skin and increase the comfort.

[0031] Specifically, the placement seat 7 is an overhead structure, and the placement seat 7 has a space that passes through from left to right. The width of the jacket 6 is slightly smaller than the width of the inside of the placement seat 7, and the bottoms of the left and right jackets 6 are movably placed inside the placement seat 7.

[0032] In this embodiment, when the left and right end jackets 6 are movable and adjusted, their bottoms can also be properly placed inside the placement seat 7, so as to support and isolate the skin and limbs.

[0033] The working process of the utility model is as follows: firstly, the limb fixing device for peritoneal dialysis is placed on a flat surface such as a bed surface. When performing peritoneal dialysis, firstly, the knob 3 is turned to control the threaded rod 2 to rotate and pull away the positions of the left and right end movable seats 5, and the elastic pad 9 is pulled and stretched, so that the patient's limbs are placed on the top of the placement seat 7 in the middle of the left and right end jackets 6. Secondly, the knob 3 is turned again to shorten the distance between the jackets 6, so that the inner side of the jackets 6 clamps the left and right sides of the patient's limbs. At the same time, the elastic pad 9 will also shorten and contact the patient's skin tightly, so as to isolate and prevent accidental injury. Finally, dialysis work can be performed.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
