Description
Technical field
This utility model belongs to the armarium technical field, specifically, relates to and is used for device that extracorporeal circulation liquid is heated on the hsempdiakysing systems.
Background technology
In blood purification treatment, be back in the intravital process behind the intravital blood lead body of the patient external purifying, will cause scattering and disappearing of heat, can cause that patient shivers, health feels cold, spirit is shunk, and cause vasoconstriction, spasm, joint ache, multiple complications even threat to life safety such as have a stomach-ache.Therefore, requirement must be heated extracorporeal circulation liquid in blood purification treatment at present, with the additional heat loss, generally adopt the method for heating fluid road system liquid to carry out heat exchange clinically by means of dialyser, the blood of the heat that scattered and disappeared outside the lead body is carried out the heating of necessity.Early stage blood purification heater is heating and pick off to be placed in the liquid road directly liquid is heated and temperature detection, and the easy dirty of heater, corrosion are polluted liquid, clean trouble before using; Or twine on the tube wall of loop and add thermal sensing device and carry out indirect and temperature survey, but this indirect thermometric is accurate inadequately, control temperature instability.So began afterwards generally to adopt safer, health, add thermal control more accurately the hot plate mode extracorporeal circulation liquid is heated.
At notification number is CN200951223, the day for announcing is JIUYUE in 2007 26 days, name is called in the Chinese utility model patent of " blood purification flat heating device ", be that the heating bag that will contain drainage tube is placed on the thermal transfer plate, the thermal transfer plate below is provided with heater, heating bag is serially connected in the extracorporeal circulation liquid line, and whole device is packed in the box, and temperature transducer is installed in drainage tube and stretches out the outer outfan of box body.Its defective is that temperature transducer remains by the temperature of measuring the liquid line outer wall and realizes indirect measurement to temperature of liquid, because away from heater itself, thereby be difficult to heater power be carried out in good time accurately control according to testing result, the heater output is lacked effective monitoring, poor stability; Whole device lacks necessary provision for thermal insulation, influences control accuracy
The utility model content
Problem to be solved in the utility model provides a kind of control accuracy height, uses safer hsempdiakysing systems heating plate device.
For solving the problems of the technologies described above, the hsempdiakysing systems heating plate device that this utility model provides, include base plate, cover plate, heater and heat transfer plate, heater and heat transfer plate are installed in the box that is made of base plate and cover plate, and heater is positioned at the below of heat transfer plate, be embedded with two temperature sensors on the heat transfer plate, one of them temperature sensor is used for monitoring the temperature of heat transfer plate and feeds back to control system carries out timely adjustment to the heater output, and another temperature sensor is used for the heat transfer plate maximum temperature is carried out independent monitoring specially.
The liquid bag that drainage tube will be housed during use lies on the heat transfer plate, and input, the outfan of drainage tube is connected with the joint of extracorporeal circulation pipeline respectively, covers cover plate then, makes liquid bag concora crush between heat transfer plate and cover plate.When liquid enters the liquid bag, heater is started working, and utilizes the environment temperature sensor that is arranged on the main frame casing that the ambient temperature before starting working is detected, the initial power when starting working with the decision heater.In the heater work process; being inlaid in one of them temperature sensor monitors on the heat transfer plate the temperature of heat transfer plate and feeds back to control system the heater output is carried out timely adjustment; another temperature sensor is used for the heat transfer plate maximum temperature is carried out independent monitoring specially; make temperature of liquid can not be higher than 41 ℃, reach the purpose of protection patient safety.Temperature sensor directly detects utilization to the temperature of heat transfer plate, detects more direct; Utilize two temperature sensors and combining environmental temperature sensor to realize data acquisition and feedback control, detect more comprehensively, temperature controlled precision of easier realization and accuracy use safer.
Above-mentioned heater is sealed between capping and the heat transfer plate, is provided with insulator below capping, and the inwall of base plate is provided with heat-barrier material, is provided with insulating collar between the faying face of base plate and cover plate, and the inwall of cover plate is equipped with thermal insulation board.After heater and heat transfer plate taked above-mentioned provision for thermal insulation, can reduce the loss of heat to greatest extent, and make the monitoring of temperature sensor more accurate.
The technique effect that this utility model is obtained is: temperature monitoring is accurate more, reliable with control, uses safer.
