Abstract
The present invention relates to an electro-thermal energy storage transfusion warmer which is composed of an electric heating part, a dielectric heat storage part and a heat insulation part. An electro-thermal container combines electric heating operation and dielectric heat storage. An electrode couple is arranged in dielectric liquid for heat storage. Both input ends of an alternating current power supply are respectively connected with one electrode of the electrode couple. Before transfusion, the electro-thermal energy storage transfusion warmer can be energized firstly to carry out heating operation for about 3 to 5 minutes according to the change of a room temperature. After a power supply is cut off, a transfusion tube can be maintained within a temperature range to which a human body is adapted, and the temperature can be maintained for dozens of minutes. The electro-thermal energy storage transfusion warmer can continuously and effectively heat a transfusion tube, increase the safety, and repeatedly heat a transfusion tube for repeated use. The present invention has the advantages of energy saving, environmental protection and safe use.
Description
Technical field
The present invention relates to a kind of transfusion additional device, particularly a kind of electric heating energy storage device of the insulation that is used to infuse.
Background technology
In the present clinical treatment, the transfusion medicinal liquid is room temperature or cold preservation, temperature of liquid often is lower than body temperature, make patient's discomfort even fear of cold behind the input sick body, especially in cold season, patient's state of an illness is increased the weight of, use hot water bag, hot towel to give the transfusion hot compress at first, innovation and creation afterwards various electrical heating or chemistry heat the infusion warmer tool.Thermostat is still rare but the transfusion that really obtains even to this day, the penetration and promotion application is heated.The electrical heating device of heating, CN1375338 for example, CN2426741 makes heating wire or resistive film heating by galvanization, heat energy reaches tube for transfusion with the heating medicinal liquid, must switch on simultaneously and infuse during transfusion, as use the 220V alternating current, make the people produce insecurity, worry to touch the electric leakage accident, have a power failure or power supply trouble etc. increases patient and medical personnel's mental burden.Another kind of cold disposable infusion bag of heating relies on the generation heat of exothermic chemical reaction to heat to medicinal liquid, and manufacturing process is complicated, the only disposable use of cost height, and the chemical refuse contaminated environment of generation increases the burden of environmental conservation.There is the defective of structure and composition separately in the constant temperature utensil of heating of above-mentioned two classes, restricted its ability to accept with ruck applied in medical industry.Therefore safe and reliable, cheap and good-quality infusion heating device is still particularly pressing for of transfusion patient of people.
Summary of the invention
The objective of the invention is to be used for the transfusion existing defective of thermostat of heating at above-mentioned two classes, design a kind of not only safe and reliable, but also good and cheap, long-lived electric heating energy storage infusion warmer.
The present invention realizes above-mentioned target by the following technical solutions.
Electric heating energy storage infusion warmer, it comprises power supply, temperature controller, electric heating vessel and heat-insulation layer thereof, electric heating vessel includes storage thermal electrolysis matter liquid, pair of electrodes places in the storage thermal electrolysis matter liquid, two inputs of alternating current power supply link to each other with an electrode of electrode pair respectively, and the solute that it is characterized in that electrolyte solution comprises the mixture of alkali metal salt, alkali salt or above-mentioned two kinds of chemical compounds; Solute accounts for 1～3% of gross weight in the electrolyte aqueous solution; Electrode is iron-nickel alloy electrode or ferrochrome electrode or ferrum rare earth alloys electrode.
Described electric heating vessel is a Baltimore groove, contains storage thermal electrolysis liquid in this groove, and the minim pipette of transfusion is clipped in the middle of the electric heating vessel, and Baltimore groove is the soft insulating vessel that insulant is made, and also can be the rigid insulation container.
Described storage thermal electrolysis liquid is the aqueous solution of alkali metal salt or alkali salt, comprises hydrochlorate, sulfate, phosphate and carbonate, and the aqueous solution of hydrochlorate and sulfate, phosphate and sulfate mixture.
Described electrode pair is an alloy high resistance electrode of the same race, also can be alloy high resistance electrode not of the same race, comprises the iron-nickel alloy electrode, ferrochrome electrode or ferrum rare earth alloy electrode.
The construction features of above-mentioned electric heating energy storage transfusion thermophore is to change electric energy into heat by the high resistance electrode, reach electric field energy and be transformed into heat energy, this thermal energy storage is in the accumulation of heat electrolyte solution, when accumulation of heat solution reaches rated temperature, the temperature controller disconnecting circuit stops the heating of storage thermal electrolysis matter solution.Give the tube for transfusion that is clipped in the electric heating vessel with the Reasonable Speed unidirectional delivery by adding the heat-insulation layer heat, thereby the transfusion of the tube for transfusion of flowing through is heated, after cutting off the electricity supply, storage thermal electrolysis matter solution still can be effectively to liquid heat in the tube for transfusion, and not charged transfusion increases the security, can heat repeatedly, reuse, reach energy-conserving and environment-protective, the purpose of safe handling.
