Description
Technical field
This utility model relates to medical apparatus and instruments, specifically, relates to a kind of heater for transfusion.
Background technology
Giving patient's transfusion when (comprising blood transfusion liquid, loading liquid), the temperature of used liquid (blood or medicinal liquid) often is lower than patient temperature, (for example used blood is the banked blood of getting from blood bank when the temperature difference is larger, perhaps medicinal liquid is in very low ambient temperature), after liquid is input in the patient body, can produce comparatively strong low temperature stimulation to the patient, make the patient untoward reaction such as feel cold of pain, health occur, can cause blood vessel wall generation spasm when serious, what impact was infused normally carries out delay treatment.
For above-mentioned situation, general way is that the packed or bottling liquid (blood or medicinal liquid) that will soon use is first put into hot water and soaked in the Hospitals at Present, after its temperature rises near patient temperature, it is taken out from hot water, hang on the drip stand and infuse to the patient.Although this method can reduce the untoward reaction that causes because of the temperature difference, but transfusion time is often very long, in infusion process, used packed or bottling liquid can be gradually function of environment heat emission towards periphery, its temperature descends gradually, temperature and the gap between the patient temperature of the liquid in the input patient body increase gradually along with the passing of transfusion time, still untoward reaction can occur in the transfusion later stage.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of heater for transfusion, this heater for transfusion can be heated to liquid continuous, make the temperature of the liquid in the input patient body all the time close to patient temperature, avoid the untoward reaction that causes because of the temperature difference.The technical scheme that adopts is as follows:
A kind of heater for transfusion is characterized in that comprising warmer and lower warmer; Upper warmer comprises heating container body and container cover, heating container body upper end is provided with vessel port, container cover is installed in the vessel port, heating container body bottom is provided with infusion tube via hole, be provided with mezzanine space between the inwall of heating container body and the outer wall, the outer wall of heating container body is provided with the first water inlet and the first outlet that is communicated with mezzanine space; Lower warmer comprises tank, tank is in heating container body below, tank is provided with the second water inlet that is communicated with the cavity of tank, and described the first outlet is communicated with the second water inlet by water-supply-pipe, and the outer wall of tank is provided with the tube for transfusion containing groove.
During use, in mezzanine space, add hot water (in case of necessity by the first water inlet, before adding hot water, the emptying water that originally remained in mezzanine space and the tank cavity of elder generation), the hot water that adds can enter in the cavity of tank through the first outlet, water-supply-pipe and the second water inlet, all is full of hot water in last mezzanine space and the tank cavity; The temperature of institute's heating water is generally equal to or a little more than patient temperature.Packed or the bottling liquid that then will soon be used for transfusion is put into the heating container body, and container cover covered in vessel port, tube for transfusion embeds in the tube for transfusion containing groove after passing infusion tube via hole, like this, hot water in the mezzanine space can be heated to packed or bottling liquid, and the hot water in the tank can further be heated to the liquid of the tube for transfusion of flowing through.
Usually, above-mentioned the first water inlet is located at the position near the vessel port of heating container body, and the first outlet is located at heating container body bottom, and the second water inlet is located at the tank top.
The outside of preferred above-mentioned heating container body is coated with heat-insulation layer, to reduce thermal loss.
Usually be provided with at the heating container body and be linked with, whole heater for transfusion can be hung on the drip stand by being linked with.
Preferred above-mentioned tube for transfusion containing groove is circular groove (being that inner surface is the groove of arc surface), the arc surface diameter of this circular groove is consistent with the external diameter of tube for transfusion, like this, after tube for transfusion embeds in the tube for transfusion containing groove, tube for transfusion outer surface and tube for transfusion containing groove inner surface close contact can be guaranteed better heat transfer efficiency.
In the infusion process, after hot water in mezzanine space and the tank cavity is heated to transfusion liquid, himself temperature can descend, in order to make the hot water in mezzanine space and the tank cavity keep required temperature, in infusion process, the hot water in mezzanine space and the tank cavity can be changed.
In a kind of scheme, above-mentioned tank is provided with the second outlet that is communicated with the cavity of tank, and the second water outlet is provided with switch valve.During use, can adopt more heat-exchanging water of manual operation.Add hot water from the first water inlet when needing more heat-exchanging water, and the opening switch valve, the second outlet is opened, from the second outlet draining; After finishing the operation of heat-exchanging water more, the closing switch valve cuts out the second outlet.The second outlet is located at the tank bottom usually.
In the another kind of scheme, in order to realize automatically more heat-exchanging water, above-mentioned heater for transfusion also comprises hot water supply apparatus, and hot water supply apparatus comprises boiler, temperature sensor, electric heater unit, control circuit, water pump, feed pipe and return pipe; Temperature sensor is in the cavity of boiler, and electric heater unit is installed on the boiler, and temperature sensor is connected with the corresponding input of control circuit, and electric heater unit is connected with the corresponding outfan of control circuit; Boiler is provided with feed water inlet and the water return outlet that is communicated with the boiler cavity; The feed water inlet is communicated with the first water inlet by feed pipe, and water pump is located on the feed pipe; Tank is provided with the second outlet that is communicated with the cavity of tank, and the second outlet is communicated with water return outlet by return pipe.Electric heater unit can heat the water in the boiler; Temperature sensor is for detection of the temperature of the water in the boiler.When the water temperature that detects when temperature sensor is lower than preset temperature, output signal to control circuit, control circuit makes the electric heater unit energized, to the heating of the water in the boiler, water temperature is risen; When the water temperature that detects when temperature sensor reaches preset temperature, output signal to control circuit, control circuit makes the electric heater unit deenergization, suspends heating.After starting water pump, hot water in the boiler enters in mezzanine space and the tank cavity through feed water inlet, feed pipe, the first water inlet, original water then is back in the boiler through the second outlet, return pipe, water return outlet in mezzanine space and the tank cavity, thereby realizes automatically more heat-exchanging water; Be back to water in the boiler after electric heater unit heating, water temperature is increased to temperature required, can again supply with in mezzanine space and tank cavity, realizes that water circuit adds heat utilization.When only needing the intermittent hot water of changing in mezzanine space and the tank cavity, can one switch valve be set at the second water outlet, opening switch valve when needing more heat-exchanging water is finished closing switch valve after the operation of heat-exchanging water more.
This utility model can be realized transfusion liquid is continued to heat, and carried out for two steps by heating container body and tank and heat, heating effect is good, makes the temperature of the liquid in the input patient body all the time close to patient temperature, avoids the untoward reaction that causes because of the temperature difference.This utility model is simple in structure, and manufacturing cost is lower, and is easy to use.
