Description

Electronic auto-controlling heating apparatus having thermal insulation

This utility model relates to the heating and heat-insulating device that a kind of clinical treatment is used, and particularly a kind of electronics of work such as transfusion, blood transfusion, bladder irrigation that is applicable to is controlled heating warmer automatically.

In clinical treatment work, often need transfuse blood, infuse or the indwelling catheter patient is carried out bladder irrigation the patient.For avoiding in the liquid holding bottle temperature of liquid low excessively, general normal employing hot water bag or electric blanket are wrapped liquid holding bottle, so that temperature of liquid is consistent with human body temperature in the liquid holding bottle, otherwise, can cause infusion reaction.Adopt the method troublesome poeration of hot water thermal insulating, particularly the hot water cooling is fast in the winter time, is difficult for reaching ideal heat insulation effect.Wayward with the electric blanket heating-up temperature, when clinical heating, there is the body phenomenon to produce, influence the clinical treatment effect.

The purpose of this utility model provides a kind of electronics and controls heating warmer automatically, it is compact conformation not only, and volume is little, and realizes the constant temperature insulation reliably when heating, liquid level is monitored automatically, can significantly improve the clinical treatment effect and alleviate medical personnel's labor intensity.

The purpose of this utility model is achieved in that this device comprises and has the shell body of hanging, the inner housing that can pack liquid holding bottle into and electronic automatic control system thereof, wherein the corresponding part with inner housing of shell body is provided with the opening trough_like observation port, and the shell body sidewall is provided with acoustic-optic alarm.Inner housing is provided with the heating wire that critesistor is controlled near liquid holding bottle mouth one end, can monitor the infraluminescence pipe and the receiving tube of liquid level in the liquid holding bottle, is symmetricly set in the opening trough_like observation port grooves on two sides.

Because this utility model adopts the assembled housing, the heating wire of critesistor control is located on the inner housing, so compact conformation, safe and reliable, the opening trough_like observation port that inner and outer shell is provided with, infraluminescence pipe and receiving tube are more effectively played a role, be contained in acoustic-optic alarm and temperature regulating switch on the shell body sidewall, made things convenient for patient and medical personnel to observe, not only processing ease monitors directly perceived, and realize constant temperature insulation reliably by electronic automatic control system, liquid level is monitored automatically, guarantees medical effect, helps alleviating medical personnel's labor intensity.

The utility model is described in further detail below in conjunction with accompanying drawing.

Describe concrete structure of the present utility model in detail according to Fig. 1-9.This device comprises having hangs 3 shell body 1, the inner housing 2 and the electronic automatic control system thereof of the liquid holding bottle of can packing into.Wherein shell body 1 and inner housing 2 corresponding positions are provided with opening trough_like observation port 7 and 10.Shell body 1 sidewall is provided with the supply socket 4 that electronic automatic control system can be installed and the cavity of electronic circuit board, is processed with indicator lamp hole 5 and temperature regulating switch hole 6 at one side cavity.Inner housing 2 is provided with the heating wire 8 of critesistor RT control near liquid holding bottle mouth one end, the both sides of opening trough_like observation port 10 are processed with transverse concave groove 9, during assembling, ready made electronic circuit board and supply socket 4 are respectively charged in the shell body 1 sidewall cavity, again inner housing 2 is packed into and reinforce in the shell body 1, and make the display lamp of acoustic-optic alarm in the electronic automatic control system and indicator lamp hole 5 and the temperature regulating switch hole 6 that temperature regulating switch exposes shell body 1 respectively.Infraluminescence pipe and the receiving tube symmetry that can monitor liquid level in the liquid holding bottle are placed in the opening trough_like observation port grooves on two sides 9.

Electronic automatic control system comprises that constant temperature is incubated automatic control section, liquid level automatic monitoring warning part and power supply voltage stabilizing part (as shown in Figure 9).Wherein constant temperature is incubated automatic control section and forms bleeder circuit by R8, W, R9, RT, RT is a critesistor, it is installed in lower housing portion, fluid temperature is converted to the signal of telecommunication and amplify by IC1-3, form voltage comparator by R11, R12, R13, R14, K and IC1-4 again, temperature current potential after amplifying is compared with setting current potential, and its result triggers controllable silicon T control heating wire RL switching electricity through R16, EL4, realizes heating and thermostatic control.Stir temperature regulating switch K and can set different constant temperature scopes.EL4 can display working condition.When heating, display lamp EL4 is luminous, otherwise just not luminous.

Whether the liquid level automatic monitoring warning is partly surveyed medicinal liquid and is used up by infraluminescence pipe and receiving tube, EL3, EL1 and finish.When opening has liquid, the output of EL1 no signal, when liquid will use up in do not pack into bottle or the bottle, EL1 had signal output, this signal amplifies to IC1-1 through C1, give audion BG1 then, make the C2 two ends become electronegative potential, thereby make EL2 luminous by high potential, IC2 and JT send fast sound simultaneously, make in addition and the D1 conducting force heater to quit work, realize the liquid level warning and the function that quits work automatically.

The voltage voltage stabilizing is partly formed power supply blood pressure lowering and filtering by C5, D2, D3, C4, R15, finishes power supply voltage stabilizing task by IC1-2 then.This device does not adopt transformator and adopts capacitance decompression, consumes the mode of voltage stabilizing, so compact conformation obviously reduces volume.
