Description
Technical field
The utility model belongs to field of medical article technology more particularly to a kind of transfusion heater.
Background technique
Infusion (loading liquid, blood transfusion liquid) typically refers to input large bolus injection liquid/blood into human body by intravenous drip
Process, medical fluid/blood is packaged in the infusion bottle or bag of glass or plastics, is free of preservative and bacteriostatic agent.Make
With when by infusion apparatus adjust drop speed, medical fluid/blood is steady and sustained to be inputted by vein, have supplement human body moisture,
Electrolyte, while being also applied for not can be carried out the patient of oral nutrient the effects of adjusting osmotic pressure in human body.Therefore infusion/blood
As a kind of medical procedure, had been widely used in the treatment of clinical disease.
In general, medical fluid storage temperature is below 20 °, and it can be lower in the temperature of winter medical fluid, especially blood is all
It is refrigerated in refrigerating chamber, temperature is lower.Since the lower medical fluid/blood of temperature can generate stimulation to blood vessel, thus patient is carrying out
When loading liquid/blood, usually using hold perfusion tube increase medical fluid/blood temperature, alternatively, by do not run out of rice and fuel hot water and
Alleviate the malaise symptoms such as loading liquid/blood bring chilly using the methods of hot-water bottle.Simultaneously because in the reason of refrigerating blood
Often there is the clot of partial agglomeration, these clots during blood transfusion be easy blocking blood transfusion tube, be unfavorable for infusion smoothly into
Row.
For these problems during loading liquid/blood, there has been proposed the methods of many solutions.For example,
200410025664.X discloses a kind of electric heating energy-storage infusion warmer, and the electric heating energy-storage warmer is by electric heating, electrolyte heat accumulation
With insulating heat conduction holes part form, wherein electric heating and electrolyte heat accumulation are combined into one, electrode contraposition in heat accumulation electrolyte solution,
With alternating current to 3-5 minutes heating electrolyte solutions of electrode energization after, the electric heating energy-storage warmer of cutting off the power can hold perfusion tube
It resumes and leads dozens of minutes.Patent 201420827305.5 discloses a kind of transfusion bag heater, which includes shell
Body and hook positioned at case top are equipped with heating sheet at shell semi-circular tube internal cavities position, can add to bags of blood
Heat；It is in close contact between heating bag and infusion bag, can reduce energy consumption.Infusion bottle or transfusion bags are added using heating device
Heat or production can heating transfusion bag etc., these technologies increase the fluid temperature before infusion/blood to a certain extent, alleviate and suffer from
The discomfort of person, but still have some disadvantages:
(1) heating method is dangerous: electric heating energy-storage infusion warmer carries out electrolyte solution using electric pole type heating method
Heating, electrolyte solution gasification is serious during the energization for this method, and electrode tends not to be completely soaked in a liquid, leads to electricity

In the risk for bringing unexpected injury to user.
(2) heating device volume is big: electric heating energy-storage infusion warmer and transfusion bag heater volume are all bigger, are unfavorable for
Individual during infusion/blood matches.
(3) temperature actuated is complicated: electric heating energy-storage infusion warmer and transfusion bag heater realize transfusion temperature control operation
Process very complicated is unfavorable for user's use.
(4) manufacturing cost is high: component is more in electric heating energy-storage infusion warmer and transfusion bag heater device, at high cost,
It is unfavorable for being widely used to promote.
