Abstract

The utility model relates to a transfusion device with a heating device. The transfusion device with a heating device comprises one main body of the transfusion device and a temperature control element connected with a power supply. The output end of the temperature control element is directly connected with an electrothermal element. The transfusion device with a heating device also comprises a short pipe arranged in a region of the lower part of the main body of the transfusion device and a clamping element for grasping the short pipe. The clamping element is enclosed on the outer part of the electrothermal element. A transfusion medium is heated by a simple structure or a device. Any poison-side effect can not be generated to a human body.

Description

A kind of transfusion device reaches and is its heater

This utility model relates to a kind of transfusion device and is this transfusion device heater in case of necessity.

The transfusion device of clinical practice when the body temperature of room temperature and human body differs greatly, can bring discomfort to patient, even can bring out other pathological changes, so should regulate the temperature difference between infusion medium and the human body in case of necessity when transfusion.Regulating the best mode of the temperature difference is that transfusion device is heated, announced " a kind of infusion set of energy regulator solution temperature " as Chinese patent CN87203628U, this device utilizes by the heater of attemperating unit control and directly the outfan of existing transfusion device is heated, and reduces the temperature difference between infusion medium and the human body with this.But existing transfusion device generally all is to be made by pvc material, and the heat stability of polrvinyl chloride is relatively poor, easily makes harmful chloride ion separate and enter in the human body with infusion medium to a certain position of transfusion device direct heating, causes adverse consequences.

Task of the present utility model provides a kind of transfusion device and is its heater, and it can prevent effectively that harmful substance enters in the human body in to transfusion device heating process.

This utility model comprises a transfusion device main body, with temperature control parts that join with power supply, this temperature control parts outfan directly and electroheat member join, described transfusion device lower body part zone is provided with the short tube that has no side effect when being heated, and is coated on the hold assembly that is used to catch described short tube of electroheat member outside.

Described short tube can be made by glass or nontoxic plastic material.

Described electroheat member can be made of the conducting polymer with positive temperature coefficient.

This utility model just can thoroughly solve the infusion medium heating problems, so structure is simple especially because only need a better heat stability and nontoxic short tube be installed on former transfusion device specific features; The heater block of Cai Yonging is to be made of conducting polymer simultaneously, its temperature of temperature control component controls is arranged, so heater block big fluctuation can not occur in the temperature preset range again.

Schematic appearance when accompanying drawing 1 is this utility model user mode;

Accompanying drawing 2 is cut-away section structural representations of hold assembly among Fig. 1.

Referring to Fig. 1, it comprises transfusion device main body 1 and heater 2, and transfusion device main body 1 is basic identical with transfusion device of the prior art, and it is to be made by pvc material cheap, that flexility is good.The lower area that different is in transfusion device main body 1 preferably is equipped with the good short tube of thermal stability 12 in the bottom of filter 11, short tube 12 is preferably selected the non-conductor of heat for use and the material that has no side effect constitutes, as glass or nontoxic plastic material etc.

Heater 2 comprises hold assembly 21 and for this hold assembly provides the temperature control parts 22 of equilibrium temperature, and the link that joins with power supply.During to 1 heating of transfusion device main body, catch above-mentioned short tube 12 with hold assembly 21 earlier, energized is adjusted temperature control parts 22 according to ambient temperature more then, makes it reach the temperature that is suitable for human body.

Referring to Fig. 2, it provides the concrete structure of hold assembly 21, and it is made of two clamp holders 211 that connect by means of axle, presses this clamp holder and can make its front portion action.Clamp holder 211 front portions are equipped with electroheat member 212, and this electroheat member top is equipped with heat-conducting block 213, and its underpart is equipped with electrode slice 214.Heat-conducting block 213 approaches the mouth part position and is provided with the groove that adapts with above-mentioned short tube 12 shapes, and it can be made of the good conductor material of heat.

Electroheat member 212 can be made of the conducting polymer with positive temperature coefficient (PTC), and when the Curie-point temperature of heating surpassed design temperature, this electroheat member can produce big impedance, and electroheat member 212 is opened circuit.
