Description
Technical field
This utility model relates to a kind of auxiliary facilities of medical apparatus and instruments, especially relates to a kind of perfusion device heater that the perfusion device is heated of being used for.
Background technology
The perfusion device is a kind of hemoperfusion when treatment armarium commonly used that carries out, carrying out hemoperfusion during low ambient temperature needs blood is suitably heated, what adopt at present is the method for the extracorporeal circulation pipeline being carried out indirect, and the limited length of extracorporeal circulation pipeline, cause heats not good, also should not guarantee ideal heats by the length of extended body external circulation line.When under the environment of cold, using the perfusion device, be difficult to reach the requirement that body temperature is satisfied in blood heat, the blood coagulation phenomenon takes place easily.In addition, when carrying out the hemoperfusion treatment, blood heat descends and mainly occurs in perfusion device position, in actual use, blood heat improves with hot-water soak pipeline or mode that the perfusion device is heated in a lot of medical institutions, but can't guarantee constant temperature, and operation is inconvenience also.
Summary of the invention
Main purpose of the present utility model provides a kind of device that can carry out heated at constant temperature to blood perfusion device.
For achieving the above object; the utility model proposes a kind of perfusion device heater; perfusion device heater; comprise the heating film that can be wrapped on the perfusion device outer wall; control unit; it is connected with heating film by a heating performance element, is connected the temperature sensor between control unit and the heating film, the protected location that is connected with the heating performance element.
By above scheme as seen, the perfusion device heater in this utility model can carry out heated at constant temperature to blood perfusion device, thereby the blood in the perfusion device is carried out heated at constant temperature, prevents that effectively the situation that blood solidifies in the perfusion device from taking place.
Description of drawings
Fig. 1 is the electric control theory block diagram of this utility model embodiment;
Fig. 2 is the circuit diagram of this utility model embodiment electric control system;
Fig. 3 is the structural representation of this utility model embodiment.
The utility model is described in further detail below in conjunction with drawings and Examples.
The specific embodiment
Referring to Fig. 1, perfusion device heater comprises heating film 2, control unit 30, heating performance element 50, temperature sensor 20, protected location 40 and the display unit 70 that links to each other with control unit 30.Wherein control unit 30 is carried out heating unit 50 by control and is controlled conduction time on the heating film 2, thereby changes the temperature of heating film 2.After starting heating, 2 pairs of perfusion device heating of heating film, the temperature data at heating film place is gathered in temperature sensor 20 in real time, and pass control unit 30 back and carry out the data operation processing, the process computing draws the real time temperature value and outputs on the display unit and shows, simultaneously control unit 30 obtains this output controlled quentity controlled variable according to error between last time real time temperature value that collects and the temperature threshold that requires to set according to medical treatment and the last controlled quentity controlled variable of exporting by fuzzy operation.The output controlled quentity controlled variable is controlled the conduction time of heating film 2 by heating performance element 50, thereby changes the temperature on the heating film, reaches thermostatically controlled purpose.
When temperature sensor 20 or heating performance element 50 when meeting accident fault, when for example the temperature on the heating film 2 surpassed design temperature+1 ℃, protected location 40 detected heating film 2 temperature anomalies, cuts off heating power supply automatically, guarantees the safety of system.
Referring to Fig. 2; heating film 2, temperature sensor 20, control unit 30, LCD display module 7, heating performance element 50 and protected location 40 constitute embodiment; control unit adopts microcontroller 31 in the present embodiment; display unit is a LCD display 7; heating performance element 50 is made of a solid-state relay 51 and peripheral circuit thereof; heating performance element 50 is controlled the conduction time of heating film 2 according to the output of microcontroller 31, thereby changes the temperature of heating film 2.Protected location 40 comprises a DC relay 41, temperature switch and warning circuit; DC relay 41 can cut off the power supply of heating performance element 50 under the control of temperature switch; temperature switch adopts a magnetic-sensing temperature switch 42; warning circuit mainly is made of a buzzer 43 and a light emitting diode 44; magnetic-sensing temperature switch 42 links to each other with warning circuit, and magnetic-sensing temperature switch 42 can detect the temperature of heating film.
When using perfusion device heater, by thermoregulation button 9 design temperature threshold values, heating film 2 begins perfusion device 1 is heated, and when the temperature of heating film rose to temperature threshold, heating film 2 was in aforementioned keeping warm mode, and holding temperature is constant.As something unexpected happened, make when the temperature of heating film 2 rise to surpass design temperature+1 ℃, promptly reach the operating point of magnetic-sensing temperature switch 42, magnetic-sensing temperature switch 42 makes DC relay 41 cut off alternating current power supply, simultaneously, buzzer 43 and light emitting diode 44 in the warning circuit send sound and light alarm signal, call user's attention.DC relay 41 in the protected location 40 and magnetic-sensing temperature switch 42 constitute the duplicate protection of heating system.
Referring to Fig. 3, heating film 2 is used to be wrapped in the outer wall of perfusion device 1 among Fig. 3.Control box 3 is connected with power supply by power line 4, and be connected by data connecting line 5 and heating film 2, the temperature sensor that is arranged on the heating film 2, control box 3 has a control panel 6, and control panel 6 is provided with the light emitting diode 44 and the heated condition green indicating lamp 11 of LCD display 7, startup button 8, thermoregulation button 9, redness.
During use, heating film 2 is wrapped on perfusion device 1 outer wall, power line 4 plugs are inserted 220V voltage, press thermoregulation button 9 and set heating-up temperature, wherein temperature regulating range is 30～37 ℃, and presses start key 8, heated condition green indicating lamp 11 is lighted, and heating film 2 begins to heat.When temperature rose to design temperature, heating film 2 was in keeping warm mode, maintains temperature threshold the blood in the perfusion device is carried out the preheating of a period of time, when the blood in the perfusion device is elevated to temperature threshold gradually, can begin to carry out the hemoperfusion treatment.Cause the temperature show value to surpass design temperature+1 ℃ in case meet accident, will trigger the heating overtemperature alarm, red light emitting diode 44 is lighted, and while perfusion device heater cuts off heating power supply automatically, guarantees security of system.
Compare with perfusion device heater of the prior art, this utility model can carry out heated at constant temperature to the perfusion device, guarantee carrying out smoothly of under the environment of cold hemoperfusion, prevent hemostasis-coagulation and shiver, and make heating-up temperature surpass when setting value to cut off heating power supply automatically meeting accident, remind the user simultaneously, have advantages such as easy to operate, simple in structure, safe and reliable.
Certainly, the foregoing description only is embodiment of this utility model, in the actual use of this utility model, more changeableization can also be arranged.For example heat performance element 50 and use IGCT to substitute solid-state relay 51 actions, perhaps display unit 70 uses light-emitting diode display etc., and these change does not influence enforcement of the present utility model.
This utility model is not limited to the foregoing description, under the situation that does not break away from main scope of this utility model and design, can have multiple other distortion, change and replacement to be included within the described scope of claims.
