Description

Technical Field

[0001] This utility model relates to the field of puncture needle technology, specifically a convenient butterfly-shaped puncture needle for internal canal puncture. Background Technology

[0002] A search revealed a Chinese patent with authorization number CN 2540972Y, which discloses a double-butterfly multifunctional intravenous puncture needle. Its structure consists of a puncture needle hub, a butterfly-shaped fixing plate, and a needle handle. The needle handle is located at the rear right side of the needle hub, and sterile silicone is placed within the needle handle. An auxiliary tube head is located on the side of the needle hub. The space between the auxiliary tube head and the sterile silicone in the needle hub lumen serves as a blood storage groove. The auxiliary tube head connects to an infusion tube with a standard needle hub and a plate-shaped shut-off valve. An interface cap is provided on the standard needle hub, and the butterfly-shaped positioning plate is located at the front of the puncture needle hub. Compared with existing technologies, this double-butterfly multifunctional intravenous puncture needle has the advantages of reasonable design, simple structure, easy processing, small size, convenient use, and multiple uses, thus possessing significant potential for widespread application.

[0003] The aforementioned patent has the following shortcomings:

[0004] 1. Existing puncture needles have a simple structure, which makes it inconvenient to fix the puncture needle during use, thus making it impossible to achieve stable puncture and force control, which increases the patient's pain and results in poor use.

[0005] 2. Existing puncture needles have a simple structure and lack a separate protective device for the needle tip. During storage, the tip is easily damaged, rendering it unusable and increasing usage costs. Utility Model Content
