[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] Example

[0026] like Figure 1-Figure 5 As shown, the utility model is a reusable indwelling needle holder;

[0027] The inner end of the arm wearing ring 1 is fixedly installed with an automatic memory steel sheet 4, the outer end of the arm wearing ring 1 is symmetrically fixedly installed with a soft silicone arc edge 5, and the lower end of the arm wearing ring 1 is equidistantly fixedly installed with a non-slip soft silicone strip 6. The automatic memory ability of the steel sheet is used to bite on the wrist, and the wearing is quick. The soft silicone arc edge 5 can improve the comfort of the patient, and the non-slip soft silicone strip 6 plays a role of non-slip and breathable.

[0028] The interface fixing buckle 2 is fixedly installed on the upper surface of the arm wearing ring 1, and a metal lining 8 is fixedly installed on the inner end of the interface fixing buckle 2. A threaded slot 9 is provided on the inner end of the metal lining 8. Reinforcement convex strips 7 are fixedly installed at equal intervals on the inner end of the interface fixing buckle 2. The reinforcement convex strips 7 are divided into two groups and symmetrically arranged on the inner side of the interface fixing buckle 2. The interface fixing buckle 2 and the interface protection part 3 are both made of silicone and can be reused after disinfection and cleaning, which is convenient for quickly clamping and fixing the connector of the indwelling needle, and quick and convenient installation and disassembly;

[0029] The end of the interface protection part 3 is integrally installed with a connecting piece 10, and a connecting thread 11 is provided on the outer surface of the connecting piece 10. The shape and position of the connecting piece 10 correspond to the threaded slot 9, and the connecting piece 10 can be threadedly connected to the inner end of the threaded slot 9 through the connecting thread 11. A silicone sheet 12 is fixedly provided at the rear end of the interface protection part 3. The connecting piece 10 is made of plastic material and has a certain elastic deformation ability. The interface protection part 3 and the silicone sheet 12 are used to cover the end of the interface to improve the safety of the indwelling needle and avoid touching and damage.

[0030] Specific working principle:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the reusable indwelling needle fixator is used, the arm wearing ring 1 is placed on the upper part of the patient's arm, the non-slip soft silicone strip 6 is in contact with the patient's skin, and then the two ends of the arm wearing ring 1 are bent inward at the same time, and the two ends of the automatic memory steel sheet 4 are subjected to the bending force, and the automatic memory ability of the steel sheet is used to bite on the wrist to complete the wearing of the arm wearing ring 1. The soft silicone arc edge 5 has an arc-shaped structure, which can improve the patient's comfort and avoid injury to the patient's skin. The non-slip soft silicone strip 6 is in contact with the patient's skin surface, playing a role of non-slip and breathable. Then the connector of the indwelling needle is pressed downward from the opening at the upper end of the interface fixing buckle 2. The elasticity of the interface fixing buckle 2 and the metal lining 8 can be used to quickly snap the interface of the indwelling needle into the interior of the interface fixing buckle 2 and fix it, and the reinforcement convex strip 7 fits tightly on the indwelling needle connector. The outer surface has a high friction force, which improves the stability of the engagement and plays a buffering and protective role for the indwelling needle connector. When no infusion is performed, in order to prevent the patient from touching it or children from playing with it, the indwelling needle connector can be plugged into the inner side of the interface protective member 3, and the connecting piece 10 on the interface protective member 3 is aligned with the threaded groove 9 provided on the interface fixing buckle 2, and the connecting piece 10 is threadedly connected to the inside of the threaded groove 9 using the connecting thread 11 to complete the installation. The interface protective member 3 and the silicone sheet 12 are used to cover the end of the interface to improve the safety of the indwelling needle and avoid touching and damage. If the interface protective member 3 is not needed, it can also be removed. The above completes a series of operations of the reusable indwelling needle holder. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
