Abstract
The utility model relates to a thermostatic heater for transfusion. The utility model can heat injected liquids which are injected into a human body under any condition of not changing the structure of an existing venous transfusion syringe, the injected liquids can be heated to a constant temperature of 35 DEG to 36 DEG and the utility model belongs to the technical field of a medical instrument. The utility model is characterized in that a thermostatic heater for transfusion is composed of an upper jacket, a lower jacket and a spring and a heating tank for a transfusion pipe is respectively arranged in the middle parts of insulative heat insulation layers of the upper jacket and the lower jacket. A heating resistor and a thermistor are arranged at the back part of the heating tank for the transfusion pipe and are connected with a power supply through conducting wires, the thermistor is arranged in the insulative heat insulation layer of the upper jacket and the heating resistor is arranged at a position of the lower jacket near the heating tank for the transfusion pipe. The utility model has the advantages of simple structure, safe and convenient operation and low cost, can be repeatedly used, can heat the injected liquids under the condition of not changing the existing transfusion pipe at any time and is a novel applicable product.
Description
Technical field: this utility model relates to a kind of transfusion thermostatic heater, and it can carry out heated constant temperature at 35 ℃-36 ℃ to the injection that injects human body not changing under the existing venous transfusion syringe any structure condition, belongs to medical instruments field.
Background technology: intravenous injection is one of main means of modern medicine disease treatment, but never consider of the influence of the temperature of injection during intravenous injection now to human body, when ambient temperature is low especially in the winter time, injection temperature in the infusion bottle is well below human body temperature, when the low temperature intravenous fluid enters in patient's body, often allow the patient feel under the weather, the patient of old people, child and body constitution difference especially experiences bad, and the utmost point is unfavorable for the sick body rehabilitation.
Summary of the invention: the purpose of this utility model is overcoming the shortcoming of prior art, invent a kind of existing transfusion syringe any structure and shape of not changing, an additional transfusion thermostatic heater on the tube for transfusion before injection enters human body just allows be about to inject the intravital injection temperature of people and remain on 35 ℃-36 ℃.
Structure of the present utility model is: a kind of transfusion thermostatic heater, it is characterized in that constituting jointly by top chuck, bottom chuck and spring, thermal insulating layer middle part at top chuck and bottom chuck has a tube for transfusion heating tank, heating resistor and critesistor are equipped with in tube for transfusion heating tank rear portion, and heating resistor is connected with power supply by lead with critesistor; Critesistor is contained in the thermal insulating layer of top chuck, and heating resistor is contained in the close tube for transfusion heating tank place of bottom chuck; Critesistor one end is connected with relay indicating light with heating resistor, and the other end is connected with power supply, and rechargeable battery is connected in parallel in the supply socket; Tube for transfusion heating tank semicircle radian and tube for transfusion tube wall external diameter coupling.
Operation principle of the present utility model is: tube for transfusion is clipped in the tube for transfusion heating tank (11) at top chuck (12), bottom chuck (13) middle part, socket (1) plugs in, heating resistor (5) is started working, and tube for transfusion heating tank (11) environment temperature rises, and the injection that flows through is heated.Heating resistor (5) is connected in series with critesistor (6), be installed in critesistor (6) monitoring transfusion pipe heating tank (11) environment temperature at any time of the thermal insulating layer (8) of top chuck (13), when temperature is higher than 36 ℃, critesistor (6) resistance value increases, and the electric current that flows through heating resistor (5) reduces, and caloric value descends, when temperature is lower than 35 ℃, critesistor (6) resistance value reduces, and the electric current that flows through heating resistor (5) increases, and caloric value rises.Because the injection liquid measure that flows through in the tube for transfusion in the unit interval is little, so only need to consume less electric energy electric weight heating, heater only needs less power just can keep tube for transfusion heating tank (11) environment temperature 35 ℃ of-36 ℃ of scopes at any time, realizes goal of the invention.
This utility model transfusion thermostatic heater profile is except that adopting clip structure, can also adopt hollow cylinder etc., then tube for transfusion directly is inserted into the middle part and has in the cylindrical transfusion thermostatic heater of bottoming hole, all the other structures are constant, can realize immediately heating the object of the invention of injection equally.
Tube for transfusion heating tank (11) in this utility model can be processed as the groove shape; Also can be directly make thermal insulating layer (8) with softish insulation material, softish insulation material can directly be combined closely with tube for transfusion automatically during use, naturally groove of formation.
This utility model transfusion thermostatic heater has simple in structure, safe and convenient to use, and cost is low, can reuse, and under the condition that does not change original tube for transfusion, heats injection immediately, is a kind of novel suitable product, and vast market prospect is arranged.
Description of drawings: below in conjunction with the accompanying drawing illustrated embodiment, this utility model structure is described further, but this utility model protection domain is not limited thereto embodiment.
Fig. 1 is the circuit diagram of this utility model transfusion thermostatic heater.
Fig. 2 is the structural representation of this utility model clip shape transfusion thermostatic heater embodiment.
Fig. 3 is a clip shape transfusion thermostatic heater deployed condition sketch map shown in Figure 2.Wherein above a width of cloth figure be top chuck cutaway view, below a width of cloth figure be bottom chuck cutaway view.
The specific embodiment: by shown in Figure 2, this utility model transfusion thermostatic heater adopts clip structure, power supply adopts 12 volts of power supplys, rechargeable battery (3) is prepared for cases of emergency such as power failures, heating resistor (5) and critesistor (6) are selected the type of market public offering for use, and relay indicating light (4) is connected in parallel with heating resistor (5).During use, the transfusion thermostatic heater of this utility model clip profile directly is clipped on one section tube for transfusion before injection enters human body, plugs in, relay indicating light (4) is lighted, heating resistor (5) operate as normal, and the injection during transfusion is heated.After having infused, powered-down, this utility model transfusion thermostatic heater quits work.
