Description

Technical Field

[0001] The utility model relates to the technical field of infusion needle protection accessories, and more specifically to an infusion needle protection device with a protection card slot. Background Art

[0002] Disposable intravenous infusion needles are used to connect syringes, infusion sets or blood transfusion sets for intravenous infusion of medicines and blood transfusions. After use, the infusion needle needle is exposed to the outside because it has no protective device, which can easily cause harm to the nurses and patients using it. In particular, the needle punctured near the scalp can easily cause harm to the patient again after being pulled out. This requires an infusion needle that can protect the needle after the infusion needle is used. A series of protection measures currently developed, such as Chinese patent CN201820640136.2, an infusion needle anti-puncture injury protective cover, CN201620766827.8, an intravenous infusion needle with a protective cover, etc., are relatively complex in structure, high in cost, and difficult to use repeatedly. There is a need for an infusion needle protection device with a protective card slot that has a simpler structure and can be used multiple times. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. The drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work:

[0015] Figure 1 It is a structural schematic diagram of an infusion needle protection device with a protection slot according to a preferred embodiment of the utility model. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be combined with the technical solution in the embodiments of the utility model for a clear and complete description. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
