Description

Technical Field

[0001] The invention relates to the field of mechanical technology, in particular to a one-handed peritoneal dialysis fluid exchange auxiliary device. 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 concentration gradient difference of solutes on both sides of the peritoneum, the solutes on the high-concentration side move to the low-concentration side (diffusion effect); water moves from the hypotonic side to the hypertonic side (osmotic effect). The peritoneal dialysate is continuously replaced to achieve the purpose of removing metabolic products and toxic substances in the body and correcting water and electrolyte imbalance.

[0003] Peritoneal dialysis generally requires four peritoneal dialysis fluid changes a day. For peritoneal dialysis patients with one-hand disability (such as hemiplegia, one-hand disability, etc.), it will be difficult to perform fluid changes independently without the assistance of others. Therefore, peritoneal dialysis brings great inconvenience to such patients. In view of this, we propose a one-handed peritoneal dialysis fluid change auxiliary device to help such patients complete the fluid change process independently. Summary of the invention

[0028] The one-hand peritoneal dialysis fluid exchange auxiliary device of this embodiment is used in the following steps:

[0029] The first step is to place the double pipe joint 511 in the corresponding peritoneal dialysis fluid double pipe joint positioning groove 41 with one hand. The shape of the groove matches the double pipe joint 511 to fix the joint and the pipeline. The rubber pull ring 513 on the double pipe joint 511 is removed with one hand to expose the port of the double pipe joint 511.

[0030] In the second step, the iodine liquid micro-cap 24 on the external short tube 2 is inserted into the iodine liquid micro-cap disassembly hole 43 with one hand, the external short tube handheld portion 24 is rotated, and the iodine liquid micro-cap 24 is disassembled from the external short tube 2 joints with one hand to expose the port of the external short tube 2 joints, and the port of the external short tube 2 joints is docked with the port of the double pipe joint 511, and the iodine liquid micro-cap 24 disassembled in the iodine liquid micro-cap disassembly hole 43 is removed and discarded;
