DETAILED DESCRIPTION

When the currently available technology is used, its airbag structure is relatively complex, the operation is difficult, and the airbag is easily damaged by the hospital's medical equipment. In addition, the technology has no thermal insulation function. During the infusion process, the liquid in the infusion tube may be at a low temperature, which may cause physical discomfort to the patient when it is injected into the patient's body.

Please refer to Figures 1 to 5. This embodiment provides a thermal insulation fixer for an intravenous catheter, including an elastic arm guard 10. Its main function is to fit closely to the user's arm due to its elastic deformation characteristics. A heating group is provided on the outer surface of the elastic arm guard 10, and a thermal insulation fixation group is provided on the inner surface of the elastic arm guard 10. Two elastic straps 11 are provided at the ends of both sides of the elastic arm guard 10 in parallel. The main purpose of the elastic strap 11 is to bind the user's arm. The front end of the elastic strap 11 is connected to one end of the elastic arm guard 10, and the end of the elastic strap 11 is connected to the other side of the elastic arm guard 10. A buckle 12 is provided in the middle of the elastic strap 11 to connect the two ends of the elastic strap 11 to each other.

First, the heating group is disclosed. The heating group includes three heating plates 20. The heating plates 20 can emit heat after being powered on. The heating plates 20 are linearly arranged on the surface of the elastic arm 10. The main purpose is to increase the heating area. A power interface 21 is provided on one side of the heating plate 20, which is located on the outer surface of the elastic arm 10. The power interface 21 is mainly used to connect to an external power supply to provide power to the heating plate 20. Through the set heating group, the internal temperature of the heating device is heated.

Secondly, the thermal insulation fixing group is disclosed, which includes an elastic thermal insulation cotton 30. The elastic thermal insulation cotton 30 has the characteristics of good elasticity and thermal insulation, can fit the user's skin, and play a role in thermal insulation. The top of the elastic thermal insulation cotton 30 is connected to the heating plate 20, and the heat emitted by the heating plate 20 can be directly conducted to the elastic thermal insulation cotton 30. An intravenous indwelling needle needle groove 31 is provided in the middle of the inner side of the elastic thermal insulation cotton 30, which is mainly used to fix the intravenous indwelling needle to prevent it from moving. An infusion tube groove 32 is provided on the side of the intravenous indwelling needle needle groove 31, and the other end of the infusion tube groove 32 is connected to the outside of the elastic thermal insulation cotton 30, which is convenient for connecting and fixing the infusion tube and avoiding squeezing the infusion tube. At the same time, the contact area between the infusion tube and the elastic thermal insulation cotton 30 is increased, and the heat conduction efficiency is increased. Through the set thermal insulation fixing group, the intravenous indwelling needle and the infusion tube can be fixed, and at the same time, the temperature in the equipment is maintained, the liquid in the infusion tube is heated, and the user is prevented from feeling uncomfortable.

The intravenous indwelling needle heat preservation fixer in this embodiment is used in the following manner:

After inserting an intravenous catheter into the patient, the elastic arm guard 10 covers the needle tip of the patient's intravenous catheter, the elastic band 11 is tied to the patient's arm, and the buckle 12 is locked. The device is fixed to the patient's arm through the elastic band 11, and the external power supply is turned on through the power interface 21 on the side of the heating group. The heating plate 20 is turned on to generate heat. The heating plate 20 transfers the heat to the elastic thermal insulation cotton 30 in the thermal insulation fixing group. The elastic thermal insulation cotton 30 receives the heat to maintain the temperature of the intravenous catheter needle and the infusion tube, and the intravenous catheter needle tip groove 31 and the infusion tube groove 32 on the elastic thermal insulation cotton 30 are used to fix the intravenous catheter needle and the infusion tube to prevent them from falling off or causing harm to the patient.
