Device for peritoneal dialysis

Abstract

The invention discloses a device for peritoneal dialysis. The device comprises a body, a first connecting hose, an irrigation and drainage pump and an upper cover plate; a box-shaped space is formed by the four side walls of the body in an enclosing mode, a liquid supply pipe, an irrigation and drainage pipe and a waste discharge pipe are integrated in the box-shaped space, the body, the liquid supply pipe, the irrigation and drainage pipe and the waste discharge pipe are integrally formed through injection molding, the irrigation and drainage pipe, the waste discharge pipe and the liquid drainage pipe are connected with three liquid flow-through ports of a first three-way valve in a one-to-one correspondence mode, and communication between every two corresponding pipes in at least pipes in pairs in a certain state is achieved; the first connecting hose connects two sections, not communicated, of the irrigation and drainage pipe, and the first connecting hose is located outside the side wall of the body; the irrigation and drainage pump is detachably connected with the body; the upper cover plate covers the upper portion of the body to form the box-shaped top wall, and one end of the first three-way valve penetrates through the upper cover plate to be connected with the liquid supply pipe, the irrigation and drainage pipe and the waste discharge pipe. According to the technical purpose, the defects that an existing peritoneal dialysis device is complex in structure and inconvenient to operate are overcome, and the device which is simple in structure and easy to operate and is used for peritoneal dialysis is provided.

Description

technical field [0001] The invention relates to the field of medical equipment. Specifically, it is a device for peritoneal dialysis. Background technique [0002] Peritoneal Dialysis (PD) is one of the more effective blood purification methods at present, and is suitable for replacement therapy of renal function after renal injury in humans. Its main principle is to pour the prepared sterile and non-pyrogenic dialysate into the patient's peritoneal cavity through the catheter, use the semipermeable membrane characteristics of the peritoneum to diffuse, infiltrate, and exchange, and constantly replace the peritoneal dialysate to achieve clearing. The purpose of metabolizing waste or toxins in the body and correcting water, electrolyte, and acid-base imbalances. The working principle of peritoneal dialysis treatment is to perfuse the dialysate into the peritoneal cavity and retain it for a period of time, then remove the exchanged waste fluid from the body, which consists o...
