摘要：
A disposable anti-acupuncture intravenous infusion puncture needle comprises a needle base (3), a needle sleeve, a flexible hose (6) and a needle head (4). The needle sleeve is sleeved on the needle head (4), the flexible hose (6) is communicated with the needle base (3). The disposable anti-acupuncture intravenous infusion puncture needle further comprises a plurality of sliding members (1, 2) and a plurality of limit mechanisms (11, 12, 13, 21, 31, 32). The needle base (3) is barrel-shaped, one end of the needle base (3) is fixed and communicated with the needle head (4), and the other end of the needle base (3) is connected with the flexible hose (6). The sliding members (1, 2) are barrel-shaped, with openings at two ends thereof. The plurality of sliding members (1, 2) are nested in each other, the sliding member (1) located at an innermost layer is movably sleeved on the needle base (3), and the total length of the sliding members (1, 2) in a movement direction is larger than the length of the needle head (4). The limit mechanisms (11, 12, 13, 21, 31, 32) are arranged on the sliding members (1, 2) and the needle base (3). With the plurality of sliding members (1, 2) being sleeved on the needle base (3) in a layered way, the operation position of the disposable anti-acupuncture intravenous infusion puncture needle is shorter in length, and when in use and after being used, the needle head (4) is shielded by unfolding the sliding members (1, 2) layer by layer, improving safety and alleviating the pain of patients.L'invention concerne une aiguille à ponction et perfusion intraveineuse jetable non dédiée à l'acupunture comprenant une base (3), un manchon, un tuyau flexible (6) et une tête (4).
