Description

A kind of SCM Based timing heated circuit

Technical field

This utility model relates to timing heated circuit field, is specifically related to a kind of SCM Based timing heated circuit.

Background technology

Low temperature infusion reaction is puzzlement medical personnel difficult problems for many years, after low temperature medicinal liquid enters vein, very easily make patient occur ice-cold, acid is swollen fiber crops pain etc. uncomfortable sensation, the symptoms such as vasospasm, shiver with cold, uncomfortable in chest, tachypnea can be caused time serious.Especially postoperative patient, baby, gerontal patient, fever patient, low temperature large capacity transfusion can cause the generation of the multiple complications such as coagulation function obstacle, wound healing are slow, extended hospital stay, the reduction of drug metabolism speed, serious even entail dangers to life, medical personnel and family members mostly taked to compensate in the method for inserting needle position hot compress in the past, this method not only uses inconvenience, and fluid temperature is fluctuated, there is certain negative effect to the stability of the property of medicine and curative effect.

Therefore need design one can timing heated, keep a kind of device of temperature constant.

Utility model content

For solving the problem, this utility model provides a kind of SCM Based timing heated circuit, can precise control of temperature, can timing heated, ensure that the stability of drug effect, practical.

For achieving the above object, the technical scheme that this utility model is taked is: a kind of SCM Based timing heated circuit, comprise single-chip microcomputer, control circuit, power supply, heating plate, tube for transfusion, temperature sensor, temperature indicator, warning circuit, reset circuit and clock circuit, single-chip microcomputer is connected with control circuit, temperature indicator, warning circuit respectively, control circuit, heating plate, tube for transfusion, temperature sensor are connected successively, power supply is connected with single-chip microcomputer, heating plate respectively, and temperature sensor, reset circuit are all connected with single-chip microcomputer with clock circuit 10; Described single-chip microcomputer 1 adopts STC89C52.

As preferably, described heating plate by half slot clip on tube for transfusion.

As preferably, described temperature sensor adopts DS18B20.

This utility model controls heating plate by control circuit, makes heating plate by the medicine liquid heating in tube for transfusion to optimum temperature 32-34 DEG C, and the absorption of human body to medicinal liquid is best at this temperature, and patient also feels comfortable.

This utility model has following beneficial effect: can control heating plate by single-chip microcomputer and carry out timing heated, the heating-up temperature of medicinal liquid is made to remain on 32-34 DEG C, ensure that the stability of drug effect, do not need manually to heat, this reduces the labor intensity of medical personnel.

Detailed description of the invention

In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.

As Figure 1-3, this utility model embodiment provides a kind of SCM Based timing heated circuit, comprise single-chip microcomputer 1, control circuit 2, power supply 3, heating plate 4, tube for transfusion 5, temperature sensor 6, temperature indicator 7, warning circuit 8, reset circuit 9 and clock circuit 10, single-chip microcomputer 1 respectively with control circuit 2, temperature indicator 7, warning circuit 8 is connected, control circuit 2, heating plate 4, tube for transfusion 5, temperature sensor 6 is connected successively, power supply 3 respectively with single-chip microcomputer 1, heating plate 4 is connected, temperature sensor 6, reset circuit 9 is all connected with single-chip microcomputer 1 with clock circuit 10, described single-chip microcomputer 1 adopts STC89C52.

It should be noted that described heating plate 4 by half slot clip on tube for transfusion.

In addition, described temperature sensor 6 adopts DS18B20.

This detailed description of the invention controls heating plate 4 by control circuit, makes heating plate 4 by the medicine liquid heating in tube for transfusion to optimum temperature 32-34 DEG C, and the absorption of human body to medicinal liquid is best at this temperature, and patient also feels comfortable; Its concrete operation principle: first the temperature value detected is passed to single-chip microcomputer by temperature sensor, shown in real time by Single-chip Controlling group of four figures pipe, and judge temperature whether in prescribed limit, for exceeding or reporting to the police respectively lower than design temperature scope, and realize the control to heater block by single chip machine controlling circuit.

This detailed description of the invention can carry out timing heated by STC89C52 single-chip microcomputer to medicinal liquid, do not need manually to heat, save time and save trouble, and can the temperature of real-time ensuring medicinal liquid basicly stable, thus ensure that the stability of drug effect, also reduce the labor intensity of medical personnel.

The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
