Description

Peritoneal dialysis device

Technical Field

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

Background

Peritoneal dialysis is to inject prepared dialysate into abdominal cavity of patient, and utilizes the characteristic that peritoneum is semi-permeable membrane to make blood in capillary vessel of peritoneum and dialysate undergo extensive material exchange so as to attain the goal of removing in vivo metabolic product and toxic material and correcting imbalance of water electrolyte and acid-base balance.

The conventional peritoneal dialysis device comprises a main pipe, an input pipe, an output pipe, a dialysate bag and a waste liquid bag, wherein the input pipe is connected with the dialysate bag and the main pipe, and the output pipe is connected with the waste liquid bag and the main pipe. The main pipe is connected with a pipeline which is placed in the abdominal cavity of a patient, the dialysate bag is hung at a high position, the waste liquid bag is hung at a low position, then the dialysate can enter the abdominal cavity of the patient through the input pipe and the main pipe, and the waste liquid can be conveyed to the waste liquid bag through the main pipe and the output pipe.

During peritoneal dialysis, balancing experiments are sometimes required, and are described in Shandong Hospital 2002, volume 42, No. 22, and in various papers.

The procedure for carrying out the balancing experiment using the conventional peritoneal dialysis set was as follows: A. putting the dialyzate left overnight in a waste liquid bag, and extracting a small amount of dialyzate to be used as a specimen; B. inputting the new dialysate in the dialysate bag into the abdominal cavity of the patient, and changing the body position of the patient; C. then the dialysate bag is lowered to make about 200ml of dialysate in the abdominal cavity enter the dialysate bag, and a small amount of dialysate is extracted as a specimen; D. raising the dialysate bag to allow the rest dialysate to re-enter the abdominal cavity of the patient; E. after two hours, repeating the step C; F. d, repeating the step D; G. after four hours, the dialysate was placed in a waste bag and a small amount was withdrawn as a specimen.

In the above steps C and E, the dialysate specimen is left to be taken, and the syringe needle is required to be punctured into the dialysate bag medicine adding opening for extraction, so that the risk of needle stick injury exists in the process.

In the above steps a and G, since the waste liquid bag usually has no output port, the dialysate sample to be taken needs to be extracted by puncturing the output tube or the waste liquid bag with the syringe, and besides the risk of needle stick injury, the needle hole after puncturing with the syringe is not easy to seal and easily causes leakage.

During peritoneal dialysis, it is often necessary to additionally infuse the abdominal cavity with some drugs depending on the patient's condition. When using conventional peritoneal dialysis device, can only pierce the syringe needle into the dislysate bag and add the medicine mouth in, inject the liquid medicine into the dislysate bag, then input the abdominal cavity again, except that equally having the needle stick and hindering the risk, because the liquid volume of adding the medicine is less, the liquid medicine is difficult to export completely again in the dislysate bag, can lead to the dose inaccurate.

In addition, among the dialysis process, the omentum in the abdominal cavity can lead to being responsible for the jam sometimes to lead to the dislysate to be difficult to input and output, conventional peritoneal dialysis device can not help the siphunculus this moment, and the siphunculus operation is comparatively loaded down with trivial details.
