Description

Technical Field

[0001] The utility model relates to the technical field of indwelling needle protection, in particular to a pediatric indwelling needle protection device. Background Art

[0002] During the treatment of young children, their blood vessels are small and fragile. Repeated punctures with traditional scalp needles not only cause great pain and fear to the children, but also increase the risk of vascular damage and infection. Therefore, pediatric indwelling needles are more commonly used. However, children are lively and active by nature. If protective measures are not taken during the use of indwelling needles, the needles may be pulled out easily, causing secondary injuries to the children.

[0003] The utility model patent with authorization announcement number CN212631350U discloses a protective mesh for an indwelling needle. The mesh comprises a protective layer, with elastic bands sewn to the top and bottom of the protective layer, a first fixing band sewn to the left side of the protective layer, a second fixing band sewn to the right side of the protective layer, a sub-strip sewn to the front of the second fixing band, and a mother-strip sewn to the back of the first fixing band. The arrangement of the protective layer, elastic band, first fixing band, second fixing band, sub-strip, and mother-strip solves the problem of indwelling needle protection easily rubbing against clothing during intermittent use, causing the film to curl and tear, and in severe cases, causing the indwelling needle protection to fall out. The mesh can effectively prevent the film from curling and tearing, which can cause the indwelling needle protection to fall out, and is convenient for users to wear, thereby improving the practicality of the mesh.

[0004] Although the indwelling needle protective net can prevent the indwelling needle from falling out, when using the device, the protective net needs to be put on the outside of the hand. This design only relies on the elasticity of the net to fix the indwelling needle. Therefore, the overall installation firmness of the net is poor, and it is difficult to achieve effective fixation of the indwelling needle. At the same time, the overall installation method will continue to tighten the child's hand, which may easily cause discomfort to the child's hand. In view of this, we propose a pediatric indwelling needle protection device. Utility Model Content
