Description
Technical Field
The invention relates to the field of peritoneal dialysis, in particular to a heater for peritoneal dialysis.
Background
Peritoneal Dialysis (PD) is a dialysis method that uses the peritoneum of the body itself as a dialysis membrane, called peritoneal dialysis for short; the dialysate filled into the abdominal cavity exchanges solute and moisture with the plasma components in the capillary vessel on the other side of the peritoneal cavity, so that metabolites and excessive moisture remained in the body are removed, and nutrients necessary for the human body are supplemented by the dialysate; the aim of kidney substitution or supporting treatment is achieved by continuously updating the dialysis solution, a peritoneal dialysis patient adopting a peritoneal dialysis treatment mode can be treated by adopting a manual or automatic peritoneal dialysis machine mode, and the manual treatment can occupy more time in the day.
The peritoneal dialysis machine has the advantages that the peritoneal dialysis machine can be used for realizing night treatment and free work and life in daytime by the peritoneal dialysis machine, the heating and temperature measurement on the heater of the existing peritoneal dialysis machine on the market are basically completed by sharing one supporting groove, before infusion treatment, the peritoneal dialysis liquid medicine bag is placed at the supporting groove for heating and heat preservation, the liquid level surface of the peritoneal dialysis liquid medicine bag is fully contacted with a heating position and a temperature sensing probe, in fact, the heating and heat preservation of the peritoneal dialysis liquid medicine bag by adopting one supporting groove are very feasible, the using method can be provided by manufacturers of the peritoneal dialysis machines for instructions and video guidance for the use of patients, meanwhile, medical personnel in nephrology department of hospitals can also train the use of the peritoneal dialysis machine for the patients, and the related use can be extremely simple, the patient who is normal and has independent action ability can correctly use the automatic peritoneal dialysis machine on the market at present to heat and preserve heat of the peritoneal dialysis liquid medicine bag for infusion therapy, and hidden risks do not exist on the basis of correct use of heating and temperature measurement of the automatic peritoneal dialysis machine on the market at present; however, once the patient carelessly operates, for example, before treatment, when the membrane dialysis solution bag is placed in the supporting groove, the liquid level surface of the peritoneal dialysis solution bag is only in contact with the heating position and is not in contact with the temperature sensing probe, so that the temperature sensing probe cannot detect the real temperature of the solution in the peritoneal dialysis solution bag, and the temperature read by the temperature sensing probe is substantially the mixed temperature of the indoor air temperature and the non-heating position of the supporting groove; in cold winter, the mixed temperature is possibly seriously lower than the real liquid medicine temperature of the peritoneal dialysis liquid medicine bag, so that the heating position continuously heats the peritoneal dialysis liquid medicine bag, the liquid medicine temperature of the peritoneal dialysis liquid medicine bag on the heating position is possibly seriously higher than 37 ℃, although the peritoneal dialysis liquid medicine bag needs to be touched by hands before the medical advice is used, the action is lost when the patient is in urgent use, or the patient is insensitive to the temperature, or the patient forgets carelessly; in hot summer, the mixed temperature is possibly seriously higher than the real liquid medicine temperature of the peritoneal dialysis liquid medicine bag, so that the heating position stops heating the peritoneal dialysis liquid medicine bag in advance, the temperature of the peritoneal dialysis liquid medicine bag on the heating position is possibly seriously lower than 37 ℃, although the liquid medicine temperature is detected by touching the peritoneal dialysis liquid medicine bag before the medical prescription is used, the action is lost when the peritoneal dialysis liquid medicine bag is used urgently, or the patient is insensitive to the temperature, or the patient forgets carelessly; because the nerve endings in the abdominal cavity of the human body are far less sensitive to cold and heat than the external skin of the human body, the peritoneal dialysis solution which is possibly seriously higher than 37 degrees or seriously lower than 37 degrees is injected into the abdominal cavity of the patient without generating corresponding cold and heat sensing reaction, the excessively high or excessively low temperature of the peritoneal dialysis solution can damage the abdominal cavity, such damage is difficult to physically detect and effectively quantify, can be attributed to either insufficient design considerations or errors in the method of use, although the probability may be extremely small, no medical accident of the automatic peritoneal dialysis machine due to abnormal heating and heat preservation caused by the misplacement of the peritoneal dialysis solution bag is actually seen, this does not represent an implicit risk of use of the heating and thermometry of currently available automated peritoneal dialysis machines.
