Description

Peritoneal dialysis assembly

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a peritoneal dialysis subassembly.

Background

Peritoneal dialysis is to regularly and regularly inject prepared dialysate into the peritoneal cavity of a patient through a catheter by utilizing the characteristic that the peritoneum is used as a semi-permeable membrane through the action of gravity, and because the concentration gradient difference of solutes exists at two sides of the peritoneum, the solute at one side with high concentration moves to one side with low concentration (dispersion action); 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 children peritoneal dialysis is characterized in that: the dosage is small, about 10ml/kg, and the requirement on dosage accuracy is high; the peritoneal dialysis catheter has small lumen, which causes slow flow rate and prolongs dialysis time; the infant patient has low fitness, is easy to be irritated and low in compliance, and is easy to shift and fold the peritoneal dialysis catheter, so that unsmooth dripping is caused; insufficient natural gravity will also result in slow flow rates and thus prolonged dialysis times. The existing peritoneal dialysis liquid inlet and outlet methods mainly depend on gravity, and the peritoneal dialysis metering method commonly used by children is an electronic scale metering method, so that the metering method has low accuracy, difficult liquid quantity guarantee and extremely easy overdose.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in the figure 1, the peritoneal dialysis set of the present invention is schematically shown, which comprises a liquid storage container 1, an infusion pump 2, a reversing valve 3, a peritoneal dialysis tube 4 and a drainage bottle 5 with negative pressure. Stock solution container 1 is used for storing the dislysate, is equipped with leakage fluid dram 11 and dosing port 12 on the stock solution container 1, and medical personnel's accessible dosing port 12 injects the medicament into the dislysate. The liquid inlet end of the infusion pump 2 is communicated with the liquid outlet 11 of the liquid storage container 1, the reversing valve 3 is respectively communicated with the liquid outlet end of the infusion pump 2, the peritoneal dialysis tube 4 and the drainage bottle 5, the reversing valve 3 is used for reversing liquid, the reversing valve 3 has an infusion state and a liquid outlet state, when the reversing valve 3 is in the infusion state, the reversing valve 3 connects the infusion pump 2 with the peritoneal dialysis tube 4, the infusion pump 2 conveys the dialysate in the liquid storage container 1 to the peritoneal dialysis tube 4 according to a preset flow value and a preset flow rate value so as to realize quantitative and constant-speed peritoneal dialysis, so that uncomfortable symptoms such as children abdominal pain caused by unstable infusion flow rate are avoided, the infusion pump 2 can ensure the infusion precision, and the condition that the dialysis quantity measurement precision is insufficient is avoided; when the reversing valve 3 is in a liquid discharge state, the peritoneal dialysis tube 4 and the drainage bottle 5 are communicated by the reversing valve 3, and the drainage bottle 5 with negative pressure can suck the dialysate in the abdomen of the child so as to discharge the dialysate in the abdomen.
