A long-time constant temperature heating device for infusion tube

Abstract

The invention discloses a long-term constant-temperature heating device for infusion tubes, which belongs to the field of medical technology, and comprises a rectangular parallelepiped body, on the top of the flat body there is a curved groove arranged in a roundabout way for placing the infusion tube, and under the curved groove A phase change material is encapsulated in the deformed body, and the bottom of the curved groove is surrounded by the phase change material. An embedded groove for placing a chemical heating unit is provided in the deformed body below the phase change material, and the chemical heating unit is encapsulated There are chemical reactants for heat generation; since the phase change material continuously releases heat at a constant phase change temperature, it ensures that the temperature fluctuation of the heated liquid medicine or blood is small, and the drug effect is good; The thermal method stores energy for phase change materials, avoiding the complicated accessories and electricity storage problems used in electric heating.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a long-time constant temperature heating device for infusion tubes. Background technique [0002] The storage temperature of the medicinal solution is usually lower than 20°C, and the temperature of the medicinal solution will be lower in winter, especially for the cold storage of blood. If the temperature of the liquid medicine or blood is too low, it will irritate the blood vessels, so it is necessary to increase the temperature when the liquid medicine or blood is transfused to alleviate the discomfort symptoms such as chills caused by the liquid medicine or blood; especially due to refrigeration There are often some coagulated blood clots in the blood, and these coagulated blood clots can easily block blood vessels during blood transfusion and cause danger to patients. [0003] Chinese Patent Publication No. CN106964031A discloses a heating device for infusion, which mainly...

AI Technical Summary

Problems solved by technology

If the temperature of the liquid medicine or blood is too low, it will irritate the blood vessels, so it is necessary to increase the temperature when the liquid medicine or blood is transfused to alleviate the discomfort symptoms such as chills caused by the liquid medicine or blood; especially due to refrigeration There are often some coagulated blood clots in the blood, and these coagulated blood clots can easily block blood vessels during blood transfusion and cause danger to patients

[0003] Chinese Patent Publication No. CN106964031A discloses a heating device for infusion, which mainly uses chemical reactants to obtain heat. Although it solves the problem of complex structure of the existing electrolytic heat method to a certain extent, the heat generated by the chemical reactants Limited is a one-time use product that cannot be reused. On the other hand, the heated infusion tube is directly wrapped around the outside of the heating body, resulting in more heat loss and low heating efficiency. It cannot achieve the purpose of long-term constant temperature heating. Especially in special environments such as winter, field disaster relief, and the patient's physical condition is extremely weak, the input of low-temperature medicinal liquid or blood will cause the patient's body temperature to drop, vasoconstriction, etc., causing secondary damage to the patient. Injury, therefore, it is also necessary to heat and keep warm the liquid medicine or blood before infusion to reduce the temperature difference with the human body

At present, although there are related patent applications for infusion heating devices, electric heating is usually used, the overall structure is complex, and it is difficult to adjust to a suitable temperature, which is inconvenient to use
