Technical Field
The utility model relates to the technical field of medical equipment, in particular to a peritoneal dialysis assembly.
Background
Peritoneal dialysis is to use the peritoneum as a semi-permeable membrane, and to inject the prepared dialysate into the peritoneal cavity of a patient through a catheter by using the gravity effect, so that the concentration gradient difference of solutes exists at two sides of the peritoneum, and the solute at one side with high concentration moves to one side with low concentration (diffusion effect); the water moves from the hypotonic side to the hypertonic side (osmosis). The peritoneal dialysis solution is continuously replaced to achieve the purposes of removing in vivo metabolites and toxic substances and correcting water and electrolyte balance disorder. The primary function of the peritoneal dialysis set is to transport the dialysis solution and the patient's body waste.
At present, after a dialysis tube group in the peritoneal dialysis component is connected with an indwelling needle, the dialysis tube group is often bonded with a connecting part of the indwelling needle so as to achieve the effects of preventing leakage and leakage, but the peritoneal dialysis component is not beautiful and the connection tightness of the peritoneal dialysis component is influenced. The name of the utility model creation of Chinese patent publication No. CN209713808U, published 2019, 12 and 3 is 'a children peritoneal dialysis device', the application discloses an infusion apparatus, an aseptic bottle, a connecting joint and a three-way joint, wherein the infusion apparatus, the aseptic bottle and the connecting joint are respectively connected with the three joints of the three-way joint; one end of the connecting joint, which is far away from the three-way joint, is connected with a peritoneal dialysis tube; and a control component for controlling the flow direction of the liquid is arranged on the tee joint. The defect is that the inner hole of the connecting joint is a single round hole, so that the transverse positioning of the dialysis tube group on the connecting joint cannot be effectively realized, and the connection tightness of the peritoneal dialysis device is influenced.
Disclosure of Invention
The utility model overcomes the defects in the prior art and provides the peritoneal dialysis component with the protective sleeve on the dialysis tube group, thereby realizing the effects of improving the sealing property of the peritoneal dialysis component, improving the connection tightness of the peritoneal dialysis component, optimizing the appearance of the product of the peritoneal dialysis component and the like.
