Abstract
Description
Technical Field
[0001] The utility model relates to human daily necessities, in particular to medical instruments, in particular to an auxiliary device for single-handed peritoneal dialysis fluid exchange. Background Art
[0002] Peritoneal dialysis (PD) uses the properties of the peritoneum as a semi-permeable membrane. The prepared dialysate is regularly and regularly infused into the patient's peritoneal cavity through a catheter by gravity. Due to the difference in solute concentration gradients on both sides of the peritoneum, the solute on the high-concentration side moves to the low-concentration side (diffusion effect); water moves from the hypotonic side to the hypertonic side (osmotic effect). The peritoneal dialysis fluid is continuously replaced to achieve the purpose of removing metabolic products and toxic substances in the body and correcting water and electrolyte imbalance. One of the obstacles to peritoneal dialysis treatment is the treatment of complications, especially peritonitis related to peritoneal dialysis. Peritonitis can lead to peritoneal failure, change the dialysis method and even death. Peritoneal dialysis generally requires four peritoneal dialysis fluid changes a day. For patients with diabetes, poor eyesight, the elderly, one-handed disability, trauma, arthritis, tremors, etc., it is very inconvenient to perform peritoneal dialysis by self-operation with both hands, which is not conducive to the long-term self-exchange of fluids at home for the above patients. Utility Model Content
[0003] The utility model aims to provide an auxiliary device for one-handed peritoneal dialysis fluid exchange, which solves the technical problem in the prior art that some patients are inconvenient to operate peritoneal dialysis with both hands at home.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] An auxiliary device for one-handed peritoneal dialysis fluid exchange comprises a shell, a clamping mechanism and at least one cap changing mechanism are arranged on the front side of the shell, a pull ring buckle is arranged on one side of the shell, and a positioning mechanism is arranged on the shell; the clamping mechanism comprises two clamps, the cap changing mechanism comprises a cap changing hole, and a limiting structure is arranged on the inner wall of the cap changing hole.
[0006] Furthermore, the positioning mechanism includes a plurality of suction cups, and the suction cups are arranged on the lower side of the shell.
[0007] Furthermore, the positioning mechanism includes a plurality of positioning holes, the positioning holes are arranged on the upper side of the shell, and screws are arranged in the positioning holes.
[0008] Furthermore, the pull ring buckle is arranged on the left side or the right side of the shell.
[0009] Furthermore, there are two cap-changing mechanisms, which are respectively located on both sides of the clamping mechanism.
[0010] Working principle:
[0011] Patients who do peritoneal dialysis have an external catheter on their bodies. The head of the external catheter is closed with an iodine cap. The iodine cap is a disposable cap. A new iodine cap is used to close after each peritoneal dialysis. The peritoneal dialysis fluid is generally contained in a bag-shaped container, and the container extends a connecting tube outward. The head of the connecting tube is generally closed with a pull ring. During use, the iodine cap and the pull ring are generally removed respectively, and then the external catheter and the connecting tube are docked, and peritoneal dialysis can be performed. When the general person operates, it is necessary to operate the external catheter with one hand, the iodine cap with one hand, or the connecting tube with one hand, the pull ring with one hand, or the external catheter with one hand, and the connecting tube with one hand, and the above operation cannot be completed by one hand. This device replaces the fixed clamping effect of one hand by a clamping mechanism and a cap changing mechanism, so that the patient can complete the above operation with one hand.
[0012] Compared with the prior art, the utility model has the beneficial effect of enabling the patient to complete peritoneal dialysis fluid exchange independently with one hand. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the embodiments and drawings of the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example 1
[0023] See also Figure 1 , Figure 2 , the utility model provides a technical solution:
[0024] An auxiliary device for one-handed peritoneal dialysis fluid exchange comprises a square shell 1, a clamping mechanism 2 and at least one cap changing mechanism 3 are arranged on the front side of the shell 1, a pull ring buckle 4 is arranged on one side of the shell 1, and a positioning mechanism is arranged on the shell 1; the clamping mechanism 2 comprises two clamps, the cap changing mechanism 3 comprises a cap changing hole, and a limiting structure is arranged on the inner wall of the cap changing hole.
[0025] Furthermore, the positioning mechanism includes a plurality of suction cups, which are arranged on the lower side of the housing 1 .
[0026] Furthermore, the positioning mechanism includes a plurality of positioning holes, which are arranged on the upper side of the housing 1 , and screws are arranged in the positioning holes.
[0027] Furthermore, the pull ring buckle 4 is arranged on the left side or the right side of the housing 1 .
[0028] Furthermore, there are two cap changing mechanisms 3 , which are respectively located on both sides of the clamping mechanism 2 .
[0029] Specifically, the housing 1 is fixed on a desktop or other location by the positioning mechanism 2 to prevent the housing 1 from moving along with the patient's operation.
[0030] Specifically, two cap-changing mechanisms 3 are used for removing old iodine caps 21 and installing new iodine caps 21 respectively, preventing patients from operating and replacing iodine caps 21 and causing pollution. Cap-changing mechanism 3 is a hole with a limited structure, and the external conduit 22 with iodine caps 21 is inserted into the hole, and the limited structure can be two parallel clamping surfaces, or the lines with damping function, and the clamping surface is used to clamp the gripping portion of iodine caps 21, and the lines with damping function are used to increase the friction with the outer surface of iodine caps 21, and the limited structure prevents the iodine caps 21 from rotating, so that when the patient can tighten or loosen the external conduit 22 with the iodine caps 21, the iodine caps 21 do not follow the rotation. The external conduit 22 connecting the abdominal cavity is long enough, and when one end of the external conduit 22 is rotated with the iodine caps 21, the part connected to the human body will not be affected, that is, the external conduit 22 will not be loosened between the human body or the human body will not be made to feel uncomfortable.

[0035] Step 2: insert one end of the iodine cap 21 on the external catheter 22 connected to the abdominal cavity into the cap changing mechanism 3 (the right side in the figure, for placing the old iodine cap 21);
[0036] Step 3: Pull out the pull ring 11. You can pull it up with one hand to separate the pull ring 11 from the connecting tube 12, or you can clamp the pull ring 11 on the pull ring buckle 4 and pull out the pull ring 11 in the reverse direction.
[0037] Step 4, rotating the external catheter 22 to separate the external catheter 22 from the iodine cap 21;
[0038] Step 5, connecting the external conduit 22 to the connecting tube 11;
