Description

A New Disposable Infusion Warmer

The utility model belongs to a medical and sanitation device, which is mainly an additional device for infusion, which is used for heating the infused liquid, and its application relates to the fields of medical treatment, sanitation and health care.

When intravenous infusion is performed in cold weather, the patient's limbs will feel cold, and in severe cases, the whole body will feel cold and shiver, and sometimes the condition may even be aggravated. This just needs a kind of long-term, stable device that warms liquid medicine, to reduce the pain of patient. And a kind of existing infusion warming device is an electric heating device, is to be heating element with electric heating wire, electric heating film, reaches the warming purpose to medicinal liquid by the heat conduction of liquid medium in medicinal liquid. However, its application is restricted by the power supply, its stability and safety are relatively poor, and its device is complicated and its operation is cumbersome, so it is not easy to popularize and use. The other is a hollow two-story one-chamber or three-story two-chamber cylindrical heating device, the hollow part is directly connected to the infusion tube, and the heating is realized by using the heat released by the chemical reaction, but its structure is complicated and the heat utilization rate is low. The heating effect is poor, and the operation is also complicated.

The utility model aims at improving the existing deficiencies of the existing transfusion warmer, and designs a novel disposable transfusion warmer which is simple in structure, convenient to use, strong in stability and safety.

The utility model is realized through the following technical solutions: a new type of disposable infusion warmer, including a heating chamber 1 and heating raw materials 2 in the heating chamber. The heating chamber 1 is a cylindrical or polygonal long cylindrical container, The cylinder wall is engraved with a "ring S-shaped" groove 3 with a large inside and a small outside, and small holes 4 with a certain aperture and interval. The arrangement of the small holes 4 can be random and the size can be different. Put on a cover that also has a plurality of small holes, and adjust the number of holes by rotating to adjust the air intake, thereby controlling the heating temperature. The heating chamber 1 is formed by injection molding of non-toxic plastic. The heating material 2 is metal powder, electrolyte solution and solid porous loose material, and its ratio is: metal powder 50-80%, electrolyte solution 10-40%, porous loose material 10-40%, and the diameter of the metal powder is required to be 0.1- 0.2mm, the diameter of the solid porous loose material is 0.2-0.3mm, the heating material 2 is filled in the heating chamber 1 and sealed 5 on the basis of stirring evenly, and finally the whole heater is sealed and packaged.

Concrete structure of the present utility model is provided by accompanying drawing 1,2.

Fig. 1 is the structural representation of the utility model.

Figure 2 is a top view of the heating chamber.

Below in conjunction with accompanying drawing, specific structure of the present utility model is described in detail.

Referring to Fig. 1, Fig. 2, the utility model is to comprise heating warehouse 1 and heating raw material 2 two parts in the heating warehouse. The heating chamber 1 is a cylindrical container, and the wall of the cylinder is engraved with a "ring S-shaped" groove 3 with a large inside and a small outside, so as to increase the contact length and area between the infusion tube and the container. The small holes 4 at intervals, the arrangement of the small holes 4 can be random, and the size can be different. The outside of the heating chamber 1 can also be covered with a cover that also has a plurality of small holes, and the number of holes can be adjusted by rotating to adjust the air intake, thereby controlling the heating temperature. The heating material 2 is metal powder, electrolyte solution and solid porous loose material. The diameter of the metal powder is 0.1-0.2mm to increase its surface area. The diameter of the porous loose material is 0.2-0.3mm to facilitate the entry of oxygen and has a certain Supporting function, the presence of the electrolyte solution will make the reaction continue to occur and accelerate the exothermic speed. The ratio of the exothermic raw materials is: metal powder 50-80%, electrolyte solution 10-40%, porous loose material 10-40%. The heating material 2 is filled in the heating chamber 1 and sealed 5 on the basis of stirring evenly, and then the whole heating device is sealed and packaged to isolate the air.

When in use, open the sealed packaging bag to allow air to enter the compartment through the small holes, and the exothermic reaction will occur immediately. Later, insert the infusion tube into the "ring S-shaped" groove, and fix the warmer on the infusion tube. 3 -After 5 minutes, the temperature in the heating chamber can rise to 50-70°C, and the temperature can last for 3-4 hours. In addition, the length of the continuous heating time and the temperature in the heating chamber can be adjusted by the size of the chamber capacity and the number and size of the air intake holes, and the air intake volume can also be adjusted by using the rotating outer cover; It can also be regulated according to the speed of the dripping speed of the medicine.

The utility model has simple structure, is not limited by the power supply when used, is convenient to operate, has high heat utilization rate, good heating effect, good safety and stability, and is not only suitable for hospital clinics, but also for families, and has a wide range of applications. It has low cost and large consumption, and is a new product with excellent social and economic benefits.
