The width of the groove is 3mm-4 mm. The utility model discloses simple structure, convenient operation, excellent in use effect, economical and durable, low cost improves work efficiency. When infusion is carried out, the infusion tube is wound in a rotating mode and fixed in the groove of the heater main body, the heating reaction contacts at the upper end and the lower end are pressed, chemical substances in the heating cavity generate exothermic reaction, a heat-conducting medium with colors changed according to temperature change is arranged in the heat-conducting cavity, the temperature of the heat-conducting medium is judged by observing the change of the heat-conducting medium through the observation port, and the infusion tube is wound in the groove and is in close contact with the heat-conducting cavity to achieve the heating and heat preservation effects.

Description

Portable Infusion Warmer

technical field

The utility model relates to a medical auxiliary device, in particular to a portable infusion heater.

Background technique

In colder weather in winter, when infusion or infusion of refrigerated blood, nutrient solution, or medical solution, it is usually necessary to heat it. Clinically, most enteral nutrition solutions are recommended to be diluted with cold or warm water, and the infusion volume is generally greater than 500ml, the speed is from 30 to 150ml/h, and the duration is longer. Because the temperature of the nutrient solution is lower, the patient often suffers from diarrhea and abdominal pain. At this time, it is necessary to heat the infusion. The traditional heating method mainly uses a heating source to continuously heat the wall of the infusion bag or infusion tube. This not only cannot control the heating temperature, but also easily leads to excessive heating time and high temperature. , so that the liquid reacts and affects the therapeutic effect. The commonly used disposable infusion constant temperature heater is packaged with a heating material inside, and after contacting with oxygen and moisture in the air, a chemical reaction occurs to generate heat. When it is in use, the infusion tube is directly wound outside the heater, so it is easy to lose heat, and it is difficult to control the heating temperature. The contact between the infusion tube and the heater is too short, resulting in a short use time of the infusion constant temperature heater and poor heating effect of the liquid medicine.

Contents of the invention

The purpose of this utility model is to provide an infusion heater to overcome the deficiencies of the prior art.

A portable infusion heater, comprising a heater body with a spiral groove on the outer surface, characterized in that an axial heating chamber is arranged in the middle of the heater body, and there is a A heat conduction chamber, and the upper and lower ends of the heating chamber are provided with heating reaction contacts, and the upper and lower ends of the heat conduction chamber are provided with observation ports.

The width of the groove is 3mm-4mm.

The utility model has the advantages of simple structure, convenient operation, good use effect, economy and durability, low cost and improved work efficiency.

Description of drawings

Fig. 1 is a schematic diagram of the planar structure of the utility model.

Fig. 2 is a schematic diagram of the three-dimensional structure of the utility model.

Among them, 1. heater main body, 2. heating chamber, 3. heat conduction chamber, 4. heating reaction contact, 5. observation port, 6. groove.

Detailed ways

As shown in Figure 1, a portable infusion heater includes a heater body 1 with a spiral groove 6 on the outer surface. 2 and the outer surface of the heater body 1 is a heat conduction chamber 3, and the upper and lower ends of the heating chamber 2 are provided with heating reaction contacts 4, and the upper and lower ends of the heat conduction chamber 3 are provided with observation ports 5.

Considering that the infusion tube is firmly fixed, the width of the groove 6 is 3mm-4mm.

When using the utility model, when performing infusion, first rotate the infusion tube and fix it in the groove 6 of the heater main body 1, press the heating reaction contacts 4 at the upper and lower ends to make the chemical substances in the heating chamber 2 generate heat reaction, the heat conduction medium in the heat conduction cavity 3 (the heat conduction medium that changes color according to the temperature change can be selected), and the change shape or color of the heat conduction medium can be observed through the observation port 5 to judge the temperature of the heat conduction medium. The groove 6 is in close contact with the heat conduction cavity 3 to achieve the effect of heating and heat preservation.

Claims (2)
