Heating tray for peritoneal dialysis

Abstract

The invention discloses a heating tray for peritoneal dialysis. The heating tray for peritoneal dialysis is provided with a liquid level contact surface for placing a peritoneal dialysis liquid medicine bag, the liquid level contact surface is provided with a heating area and a temperature sensing area, and the liquid level contact surface is also provided with a liquid level detection area; the liquid level detection area is connected with the heating area and the temperature sensing area, and the liquid level detection area is used for monitoring the flowing state of liquid medicine in a peritoneal dialysis liquid medicine bag to be used in a heating and heat preservation state in the treatment process; the flow state information of the liquid medicine in the to-be-used peritoneal dialysis liquid medicine bag is provided for the related peritoneal dialysis equipment, so the excessive injection caused by failure of a related gas circuit switch or a valve connected with the to-be-used peritoneal dialysis liquid medicine bag when the related peritoneal dialysis equipment is in a non-injection state is prevented.

Description

technical field [0001] The invention relates to the field of peritoneal dialysis, in particular to a heating tray for peritoneal dialysis. Background technique [0002] Peritoneal dialysis (peritoneal dialysis, PD) is a dialysis method that uses the body's own peritoneum as a dialysis membrane, referred to as peritoneal dialysis; through the dialysate poured into the peritoneal cavity and the plasma components in the capillaries on the other side of the peritoneum, solutes and water are exchanged. The exchange of the metabolites and excess water retained in the body can be removed, and the nutrients necessary for the human body can be supplemented through the dialysate; through continuous renewal of the dialysate, the purpose of kidney replacement or supportive treatment can be achieved. Dialysis patients can be treated manually or with an automatic peritoneal dialysis machine, and manual treatment will take up more time during the day. [0003] The automatic peritoneal dia...

Problems solved by technology

These gas circuit switches will produce tens of thousands of switching actions during the treatment process for many years. The more times of switching, the easier it is to age and fail, and the failed switches will bring various safety hazards.

Calculated by changing the liquid 4 times a day, there are 3 bags of supplementary bags for each treatment, each bag is 2000 ml, and the switch is switched once every 20 ml. There will be 109,500 more actions in the annual meeting. Based on the 8-year service life of an automatic peritoneal dialysis machine, 876,000 more actions will be performed in 8 years. The actual number of switching actions will be more, so it is more prone to wear, aging and failure

If the air circuit switch of the liquid medicine bag to be used on the heating tray fails, it is very likely to cause excessive injection, expand the patient's abdominal cavity, and even cause rupture, resulting in a safety accident
