Abstract

The utility model discloses a transfusion warming instrument which comprises a warming sleeve and a temperature controller, wherein, the warming sleeve is a semienclosed outer flexible sleeve which is made of thermal conductive materials and can contain a transfusion tube; the warming sleeve is provided with a crack along the lengthwise direction, and the infusion tube can be pressed into the warming sleeve through the crack; at least one heating element is arranged in the warming sleeve body along lengthwise direction; at least one temperature is arranged in the warming sleeve, and the heating element and the temperature sensor both are connected with the temperature controller through leads or electrical connectors. The transfusion warming instrument uses the heating element to heat the transfusion tube and the temperature controller to control the warming temperature to make transfusin liquid enter a human body at a proper temperature, thereby solving the problem that a patient feels discomfortable caused by low temperature of the transfusion liquid.

Description

The transfusion heating instrument

Technical field

This utility model relates to a kind of liquid heating, particularly relates to a kind of device of heating for institute's transfusion in the medical transfusion process.

Background technology

There is the deficiency of two aspects in the present infusion solution heating device that uses of each medical institutions, and the one, need to use special transfusion heating tube or the transfusion bag of heating, cause the increase of use cost; The 2nd, the liquid after heating apparatus is heated usually needs to import in the patient body again through one section exposed tube for transfusion, under low temperature environment and low flow rate conditions, temperature of liquid after heating can reduce again again, even near low ambient temperature, has weakened the effect of heating greatly.

Summary of the invention

The purpose of this utility model is to provide a kind of and can effectively heats with the transfusion liquid in pipe that suitable temperature is used to routine, and heats is not subject to the transfusion heating instrument of low temperature environment influence.

The technical scheme that its technical problem that solves this utility model adopts is: the transfusion heating instrument, comprise heat sleeve pipe and temperature controller, wherein, the sleeve pipe of heating is a semiclosed overcoat flexible pipe that holds tube for transfusion of being made by Heat Conduction Material, have a crack along its length at it, by this crack tube for transfusion is pressed in the sleeve pipe of heating during use; In the steam jacket tube body, be provided with at least one heater element along its length; In the sleeve pipe of heating, be provided with at least one temperature sensor; Heater element all links to each other with temperature controller by lead or electrical connector with temperature sensor.

As improvement of the present utility model, described heater element is two or more, uniform distribution on the telescopic cross-sectional direction of heating.

As the another improvement of this utility model, described temperature sensor is two, is distributed in heat telescopic head and afterbody.

The beneficial effects of the utility model are: by the heating of heater element, heat passes to flowing liquid in the tube for transfusion of the sleeve pipe Nei Baona that heats by the sleeve pipe of heating, temperature controller can make steam jacket guarantee and be held in the suitable temperature of heating according to the heating power of the temperature signal adjusting heater element of temperature sensor feedback.Simultaneously, the telescopic structure of heating can make the heating that is wrapped of tube for transfusion part as much as possible, improves heating effect, the influence of shielding low temperature environment.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 is a sketch map of the present utility model;

Fig. 2 is the telescopic cross-sectional enlarged diagram of heating.

The specific embodiment

With reference to Fig. 1, the transfusion heating instrument comprises heat sleeve pipe 2 and temperature controller 1, and the sleeve pipe 2 of heating is a semiclosed overcoat flexible pipe that holds tube for transfusion, and it is made by Heat Conduction Material, also can be made by exothermic material.The sleeve pipe 2 of heating has a crack along its length, by this crack tube for transfusion is pressed in the sleeve pipe 2 of heating during use.In sleeve pipe 2 bodies of heating, be provided with a heater element 3 along its length; In the sleeve pipe 2 of heating, also be provided with a temperature sensor 4; Heater element 3 all links to each other with temperature controller 1 by lead or electrical connector with temperature sensor 4.Temperature controller 1 is regulated the heating power of heater element 3 by the temperature signal of collecting temperature pick off 4 feedbacks, makes the sleeve pipe 2 of heating with the liquid in the suitable temperature heating transfusion pipe, thereby makes institute's transfusion be heated to the temperature that human body is fit to.

Transfusion is heated evenly in order to make, and heater element 3 is two or more, uniform distribution on the cross section of overcoat flexible pipe 2.

In order to control institute's transfusion temperature better, reach the temperature range that is fit to human body, this utility model can be provided with two temperature sensors 4, each one of the head of the sleeve pipe 2 of heating and afterbody.

This utility model is provided with the passage 5 of sealing in sleeve pipe 2 bodies of heating, be full of air in the passage 5 of sealing, and such benefit has three, one, because the minimizing of steam jacket tube body material can make rapider the reaching evenly of heating; The 2nd,, air duct can reduce distributing of heat, has insulation effect; The 3rd, because the steam jacket tube wall is thin, allow being pressed into or taking out of tube for transfusion easilier.

The foregoing description only is to description of the present utility model, protection domain of the present utility model is not done any restriction, is equal to this utility model or becomes bad technical scheme all to belong within the protection domain of the present utility model.
