In this embodiment, the track 301 and the slider 401 may be preferably made of plastic, and the track 301 and the slider 401 may have a certain toughness and may be bent appropriately within a certain range.

In addition, in the prior art, the length of the scalp needle 101 of the conventional infusion apparatus is about 2.3 cm, so in the preferred embodiment, the length of the slider 401 may be between 2.5 cm and 3 cm; the diameter of the slider 401 (when a round tube is used) is preferably set to about 0.4 cm.

Example 2

The main difference between the present embodiment 2 and the above embodiment 1 is that, in the security application provided in the present embodiment, the security application further includes a lower layer application 601, where the lower layer application 601 is in a strip shape, one surface of the lower layer application 601 is divided into an adhesive area 602 and two adhesive-free areas 603, as shown in fig. 14, where the two adhesive-free areas 603 are respectively disposed at two ends of the lower layer application 601, the adhesive area 602 is disposed between the two adhesive-free areas 603, and an adhesive 203 is disposed in the adhesive area 602; the lower layer application 601 is used for fixing the needle handle 102, the glue-free areas 603 at two ends of the lower layer application 601 are used for manually peeling off the lower layer application 601, and the width of the upper layer application 201 is smaller than or equal to the width of the glue-free area 602, as shown in fig. 15.

In daily clinical work, after the needle handle 102 of the scalp needle is inserted into the heparin cap; the medical staff can use a high-lift platform method (technical terms, those skilled in the art can understand that the description is not repeated here) to fix the needle handle 102 of the scalp needle to the lower layer application 601, and when the scalp needle is fixed, the needle handle 102 of the scalp needle is preferentially fixed at the position of the lower layer application 601; then, after the transfusion hose 103 connected to the scalp needle 101 is rewound once, the medical staff can fix the transfusion hose 103 close to the scalp needle 101 once again at the original position (namely above the lower-layer application 601) by utilizing the upper-layer application 201, so that the fixing effect of the whole scalp needle can be enhanced, and on the other hand, the lower-layer application 601 and the upper-layer application 201 cannot be adhered to the heparin cap, so that the adhesive 203 on the lower-layer application 601 and the upper-layer application 201 can be effectively prevented from being remained on the heparin cap, and the cleaning is difficult;

in applying the upper layer application 201, two points need to be paid priority:

1. in order to make the direction of the track 301 on the upper layer application 201 consistent with the direction of the scalp needle 101, so that when the transfusion is completed and the scalp needle 101 is pulled out, the medical staff can manually slide out of the slider 401 and wrap the scalp needle 101 to realize the function of preventing the injury of the sharp instrument, which is described in detail in embodiment 1 and is not repeated here.

2. Because the two ends of the lower-layer application 601 are the glue-free areas 603, and the width of the upper-layer application 201 is smaller than or equal to the width of the glue-free areas 602, when the upper-layer application 201 is applied, the upper-layer application 201 can be preferentially applied to the position above the glue-free areas 602, namely, the upper-layer application 201 does not cover the glue-free areas 603 at the two ends of the lower-layer application 601, so that the glue-free areas 603 at the two ends of the lower-layer application 601 cannot be directly applied to the skin of a patient, and a medical staff can hold the glue-free areas 603 at the two ends of the lower-layer application 601 by hands when transfusion is completed and a transfusion device is required to be removed, thereby being convenient to operate and convenient and quick to peel off the lower-layer application 601 and the upper-layer application 201.

In this embodiment, the materials of the upper layer application and the lower layer application may be the same or different, and the materials of the upper layer application and the lower layer application that are commonly used in the prior art may be respectively adopted, which is not described here again.
