Abstract
The utility model relates to an electronic heating apparatus for medical transfusion, which can heat the physic liquor and maintain constant temperature. The utility model has the technical proposal that a heating resistor and a bidirectional thyristor are connected with an AC 220V circuit in series; the catelectrode of the bidirectional thyristor is provided with a branch circuit which is connected with a varistor, a thermistor, a resistor and a diode in series, and is connected with a control electrode of the bidirectional thyristor; both ends of the resistor are respectively provided with a capacitor which is connected with the anode of the bidirectional thyristor; the heating resistor heats the physic liquor through a heat-transfer system to make the transfusion and the human body temperature are mutually compatible. When the environment temperature is between 18 DEG C and-30 DEG C, the utility model can satisfy the transfusion usage of the general medicine and the medicine providing with crystals under the room temperature.
Description
This utility model relates to a kind of transfusion heater, especially can make the homothermic medical infusion electronic heater of infusion process medicinal liquid.
At present, when known ambient temperature is lower than 18 ℃, medical transfusion will improve the temperature of medicinal liquid input human body with boiled water or hot water bag heating transfusion pipe or medicine bottle; Very inconvenient, can not eliminate the stimulation of the temperature difference to human body.
The purpose of this utility model provides a kind of medical infusion electronic heater, and it can not only heat medicinal liquid, and can effectively keep the constant temperature of medicinal liquid.
This utility model its objective is such realization: a polyphone heating resistor and bidirectional triode thyristor in the 220V alternating current circuit, and establish the control utmost point of a branch road polyphone rheostat, critesistor, resistance, diode, connection bidirectional triode thyristor at the bidirectional triode thyristor negative electrode; Respectively establish electric capacity and bidirectional triode thyristor anode at the resistance two ends and connect.The bidirectional triode thyristor conducting of energising back, heating resistor begins heating, and along with the resistance increase of temperature rising critesistor, the electric current that leads to the bidirectional triode thyristor control utmost point reduces, and bidirectional triode thyristor ends; Because exothermic temperature descends gradually, the resistance of critesistor descends, and the bidirectional triode thyristor conducting reaches the purpose of heated at constant temperature so repeatedly.
Owing to adopt such scheme, can when medical transfusion, effectively guarantee the medicinal liquid heated at constant temperature, eliminate owing to the stimulation of the temperature difference human body; Guarantee that room temperature has the transfusion heating of crystallization medicine; The convenient nursing personnel improve therapeutic quality simultaneously.
Below in conjunction with accompanying drawing and example this utility model is further specified:
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is a circuit assembly drawing of the present utility model.
Fig. 3 is the vertical section structural map of first embodiment of medical infusion electronic heater.
Fig. 4 is the part section structural map of second embodiment of medical infusion electronic heater.
In Fig. 1, contact between two leads of power line (1) heating resistor (2) and bidirectional triode thyristor (3), on bidirectional triode thyristor (3) negative electrode, a branch road is set, the control utmost point of polyphone rheostat (5), critesistor (8), resistance (7), diode (4), connection bidirectional triode thyristor (3); The two ends of resistance (7) respectively connect 1 capacitor (6) respectively, and the other end of capacitor (6) is connected with the bidirectional triode thyristor anode.Usually rheostat (5) maximum value should be not little 50 kilo-ohms.Use for assembling at the wiring point of power line shown in Fig. 2 (11), heating resistor wiring point (112), critesistor wiring point (118) wiring board (9).
In the embodiment shown in fig. 3, power line (1) is drawn by wiring board (9), fixing circuit board (9) is on bottom (13), the tubular hole (21) that to change warmware (20) inwardly is fixed on automatically controlled closing (10) top, heating resistor (2) is connected with lead-out wire (12), is inserted by tubular hole (21) one ends, and critesistor (8) and lead-out wire (18) are in succession, insert by tubular hole (21) other end, build bottom.Present embodiment is to establish one 3/4ths circular trough (22) above an approximate rectangular electric-controlled box, during use tube for transfusion is pressed in the groove, and after the energising, the constant temperature that the medicinal liquid of this groove of flowing through promptly heats up and maintenance and human body adapt.
In another embodiment shown in Figure 4, heating resistor (2) is fixed on the fabric that adapts with medicine bottle, the external woollen blanket is made heat-insulation layer (16) and is made bottle cover (15), bottle cover (15) seam crossing connect with band and the seam that stays the 5-10 millimeter as liquid level visor (14), electric-controlled box (10) is fixed on the lower end of bottle cover (15), the upper end symmetry fixedly is linked with (17), heating resistor (2) is connected on wiring point (112) on the wiring board (9) in the electric-controlled box with line, and critesistor (8) is fixed on the position near the heating thermo-flask, flask cover internal layer.The ectonexine of bottle cover is used waterproof material and is made.This embodiment is applicable to that for infundibulate bottle cover room temperature has crystalline infusion medicine, and with medicine bottle bottle cover (15) energized of packing into, crystallization is dissolved gradually, and the constant temperature that can keep medicinal liquid and human body to adapt in infusion process.
