Description
Technical field
This utility model relates to the technical field of medical auxiliary equipment, specifically a kind of device that carries out heated at constant temperature at the pipeline of medical Transfusion device.
Background technology
At present, medical Transfusion device has become a kind of medical apparatus and instruments important and commonly used, and using medical Transfusion device that the patient is treated becomes the most frequently used treatment means.But, in infusion process, particularly in the situation that the Cold Winter room temperature is lower or use the low temperature medicinal liquid and blood plasma when infusing, often can because fluid temperature is excessively low, cause the patient symptoms such as shiver with cold, medicine irritation pain and limbs discomfort to occur.
For this reason, some Medical constant-temperature heaters occurred, it can be extremely close with patient's body temperature with the liquid heating of being inputted by vein, thereby minimizing is crossed the low infusion reaction that causes because of the temperature of infusion fluid.The infusion reaction such as cold, swollen, sour, numb that has brought to the patient part because of low temperature when having solved transfusion, blood transfusion; Improve to drip speed, shorten a transfusion time, avoided the loss of indigenous method preheating to medicine, guaranteed drug effect in time with give full play to, be conducive to improve service quality.
Yet more existing constant temperature heating devices are to be made of heater and clamping device, utilize clamping device that heating apparatus is clamped on the tube for transfusion, and its heat that discharges is transmitted on the tube for transfusion of medical Transfusion device.But the heater of the medical Transfusion device of the type is because the area of clamping is little, and heat conducting efficient is lower.Therefore, when the flow of medicine in the tube for transfusion was very fast, the effect of its intensification or insulation will weaken.Simultaneously, the constant temperature heating device of the type once can only heat a tube for transfusion, can not carry out heat treated to a plurality of tube for transfusions simultaneously, when transfusion patient quantity increases, need to increase the quantity of this constant temperature heating device, thereby increased the cost of equipment and the workload of health care provider.The heated at constant temperature water tank of another kind of type then places whole bottle among the water tank, thereby has increased the volume of thermostatic water tank; When the dried up case of the syringe needle of transfusion device was far away, medicinal liquid heat loss in the process that flows was more, was unfavorable for that the fluid temperature that will input human body remains near the human body temperature scope, has lost the meaning of thermostatic water tank.
Summary of the invention
The purpose of this utility model is to provide a kind of improved heater for transfusion device, and it can overcome, and heater once can only heat a tube for transfusion in the prior art, has increased manpower and equipment cost; Perhaps volume is excessive, the uppity some shortcomings of temperature.
To achieve these goals, the technical solution of the utility model is: a kind of heater for transfusion device, it mainly comprises casing, it is characterized in that: be provided with at least two coil boxes arranged side by side in the casing, be provided with heating apparatus in the casing, each coil box is equipped with pipe box liquid inlet and outlet, and casing is provided with and the water tank liquid inlet and outlet of managing the box liquid inlet and outlet and matching.
During use, heater of the present utility model is provided with thermostatic water tank and is located at the interior heating apparatus of water tank, a plurality of coil boxes can be set in the water tank, separate by dividing plate between the adjacent coil box, pipe box on the coil box advances, liquid outlet links to each other with the transfusion organ pipe, make the liquid in the tube for transfusion device flow to pipe box liquid outlet by pipe box inlet, because the coil box is arranged in the thermostatic water tank, liquid can be heated in the process that flows, by setting the water temperature of thermostatic water tank, so that the liquid of final effuser box liquid outlet reaches the transfusion temperature of setting, this utility model is a kind of safety that can carry out constant-temp transfusion under the varying environment temperature, reliable Medical constant-temperature heater, not only dwindled the volume of thermostatic water tank, can also add simultaneously the liquid in the overabundant heat root tube for transfusion device, heat conduction efficiency is high, can reduce distributing of heat in the medicinal liquid flow process, has guaranteed the fully in time performance of drug effect.

Fig. 2 is the structural representation of this utility model one embodiment.
Fig. 3 is radiator valve control structure block diagram of the present utility model.
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
Each attached number in the figure is expressed as follows: 1 pipe box inlet, 2 pipe box liquid outlets, 3 coil boxes, 4 snake pipes, 5 water tank inlets, 6 water tank liquid outlets, 7 casings, 8 heat preservation sandwich layers, 9 electrical heating wires, 10 radiator valves, 11 electric power connection line sockets, 12 dividing plates.
A kind of heater for transfusion device described in the utility model, it mainly comprises casing, its difference with the prior art is: be provided with at least two coil boxes arranged side by side in the casing, be provided with heating apparatus in the casing, each coil box is equipped with pipe box liquid inlet and outlet, and casing is provided with and the water tank liquid inlet and outlet of managing the box liquid inlet and outlet and matching.Described casing is thermostatic water tank, be provided with heat preservation sandwich layer between the inside and outside surface layer of casing, be provided with dividing plate in the casing, dividing plate is separated adjacent coil box, and described heating apparatus is formed by connecting with the radiator valve that links to each other with electrical heating wire by electrical heating wire.Described radiator valve is provided with single-chip microcomputer and A/D signal adapter, and single-chip microcomputer is connected with peripheral hardware keyboard and temperature indicator, and the A/D signal adapter links to each other with temperature sensor by signal amplifier, and described temperature sensor is arranged in the casing.The coil box adopts the Dispoable medical plastic material to make, and is provided with snake pipe in the coil box, and the diameter range of described snake pipe is 4-6mm.
In the enforcement, the thermostatic water tank initial temperature is set as 37
, close to human body temperature, deposit 5 coil boxes in the water tank, can place according to demand a plurality of coil boxes.Coil box contact area is larger, heat conduction efficiency is high, can be quickly with the medicine liquid heating of the thermostatic water tank of flowing through to design temperature, thermostatic water tank can be positioned over simultaneously from the place of patient close to, reduced the loss of heat in the medicinal liquid flow process, thereby avoided because of the lower infusion reaction that occurs of medicine temperature.Radiator valve has extended out keyboard input circuit and temperature display circuit simultaneously, and the keyboard input circuit is used for inputting the temperature value of setting, and liquid crystal display circuit is used for the temperature of display setting, the actual temperature of thermostatic water tank, running status and the time of system.The medical worker can pass through LCDs facilities for observation working condition, and adjusts the parameters such as plant capacity, temperature and time by keyboard.
