The elastic band 200 is connected with a non-slip gripping pad 208, and the other end of the left connecting band 101 is buckled. Velcro or magnetic suction can be detachably connected to the other end of the right connecting belt 102. In this disclosure, the Velcro structure is preferred.

In this embodiment, the base pad 100 is brought into contact with the patient's arm, and then the left connecting belt 101 and the right connecting belt 102 are respectively connected around the patient's arm. After the connection is completed, the retention needle is placed on the surface of the base pad 100. After the placement is completed, the medical staff pulls the anti-slip gripping pad 208 to drive the elastic band 200 to move, and then limits the elastic band 200 through the limiting component. At this time, the indwelling needle is located in the indwelling needle fixed cavity formed between the elastic band 200 and the base pad 100 400, thereby completing the fixation of the indwelling needle; no matter what structure is used, the connection between the left connecting belt 101 and the right connecting belt 102 can achieve adjustment, so as to be suitable for patients with different arm circumferences; it should be noted that when the left connecting belt 101 and the right connecting belt 102 are connected, the The belt 101 and the right connecting belt 102 are connected as a whole. In this state, the base pad 100 is put on the patient's arm and the patient's position is fixed through elastic force, and the same effect can be achieved.

Please refer to Figures 1, 3 and 4. In some embodiments, the elastic band 200 is connected to a non-slip gripping pad 208. The limiting component includes a fixing post 201.

The arrangement of the ventilation holes 300 improves the patient's comfort and prevents part of the skin from being stuffy due to long-term fixation. In case of discomfort, the installation of wear-resistant coating can improve the overall service life.

Specifically, the working principle of the new fixation device for indwelling needles provided by this disclosure is:

The medical staff brings the base pad 100 into contact with the patient's arm, and then connects the left connection belt 101 and the right connection belt 102 around the patient's arm respectively. After the connection is completed, the retention needle is placed on the surface of the base pad 100. After the placement is completed, the medical staff The person pulls the anti-slip gripping pad 208 to drive the elastic band 200 to move until the fixing post 201 passes through the fixing hole 206, and then moves the elastic band 200 downward. First, the limit block 205 is squeezed, so that the return spring 203 is in a compressed state. , when the elastic band 200 is in the appropriate position, the limiting block 205 is ordered to enter the opening 207 under the action of the rebound force of the return spring 203, completing the fixation of the elastic band 200. At this time, the retention needle is located between the elastic band 200 and the base pad 100. The indwelling needle fixing cavity 400 is formed therebetween, thereby completing the fixation of the indwelling needle.
