Description

Human body infusion heating device

The invention relates to a human body infusion heating device, which is convenient for carrying and carrying out, and can generate heat energy as long as the power source is connected, and can add body fluid (including dialysate, physiological saline, blood, etc.). Warm action to relieve the discomfort caused by the cold infusion into the human body.

According to the fact that the proportion of Taiwan's dialysis population is the highest in the world. Hemodialysis and peritoneal dialysis are often heard for the treatment of kidney disease. Hemodialysis refers to the treatment of about 2 to 4 times a week. It takes more time, peritoneum. Dialysis is to first implant a catheter in the abdomen. The patient can operate the dressing water at home. It is not necessary to go to the dialysis center to perform treatment by the nursing staff, so that the patient can still maintain the work and quality of life; only, the winter temperature is low, cold. The potion is difficult to receive in the stomach. It is clinically proven that the heating temperature of the dialysate is the best at 37 degrees equivalent to the body temperature. Therefore, whether the patient is going to perform peritoneal dialysis at home or on the out side, the patient will heat the dialysate and start the operation. Dialysis. The heating method generally used is heating with a microwave oven or an electric blanket. When you want to go out, you should use a microwave oven or electric blanket to heat the dialysate before going out. After that, put it into the insulated bag for heat preservation. Therefore, when you want to perform peritoneal dialysis, the dialysate still maintains a certain temperature to relieve the dialysis. The uncomfortable feeling; however, the above-mentioned methods and effects of heating and preserving the temperature of the dialysate are not ideal, and there are the following disadvantages:

First, patients use microwave ovens and electric blankets to heat dialysate, and can not accurately control the heating temperature, so this heating method is not accurate.

Second, the microwave oven is heated by water molecules, there is a danger of local overheating causing deterioration of the human body fluid; while the electric blanket is used for warmth, the preset temperature is too high (for example, above 45 °C), there will be safety concerns about destroying human infusion, so It is reasonable to say that microwave ovens and electric blankets should not be used to heat dialysate. Even in home environments, microwave ovens and electric blankets should be discarded.

Third, when the patient wants to go out, he must first heat the dialysate at home, and the heat preservation device should be used to keep the patient warm and inconvenient when traveling.

Fourth, the heat preservation time must be done quite well, and it must be able to provide long-term heat preservation effect, otherwise even if the dialysate has been warmed to the most appropriate temperature, but because of poor insulation, when the peritoneal dialysis is to be performed, Only when the dialysate could not be maintained at the optimum temperature of 37 degrees, the warm work done in the morning was in vain.

5. In addition, if the infusion bag is leaking, the electric blanket has the danger of electric shock and doubts.

In view of the above situation, the inventors invested a lot of time to research relevant knowledge, and compared various advantages and disadvantages, carried out research and development of related products, and after many experiments and tests, finally introduced a "human infusion heating device" to improve the above.
