The utility model discloses a puncture proof scalp needle, comprising a needle, needle and needle cap, needle seat is fixed on one end of the needle, needle needle extending from one side of the wing, the needle cap for a hollow plastic tube is arranged and fixed with the needle sleeve needle, needle cap corresponding needle wing is provided with a guide groove, groove of the guide slot close to the needle outlet end and end guide groove are respectively provided with the corresponding needle wing, card at the end of the guide groove near the needle outlet end is provided with a hook, the hook is connected with the guide groove to the needle outlet end extends a convex, when no infusion, needle wing scalp needle raised by the card is arranged in the guide groove when; intravenous infusion needle, wing scalp needle inserted into the groove guide needle outlet; when the infusion is completed when the scalp needle, needle wing card into the guide card slot is arranged on the rear end of the hook. The anti pricking scalp needle of the utility model has the advantages of simple structure and convenient operation. When the scalp needle is used for infusion, the needle head and the needle cap can be fixed, and when the infusion is finished, the scalp needle is firmly fixed in the clamping groove at the end of the needle cap guiding groove, thereby avoiding accidental needle injury.
【技术实现步骤摘要】
本技术涉及一种头皮针,特别是涉及一种防刺头皮针。
技术介绍
针刺伤是感染乙肝、丙肝和艾滋病等血液性疾病的主要传播途径,而由针刺伤医 务人员从而引发血源感染的潜在危险正日趋严重。所造成的医务人员的职业暴露引发血源 感染的潜在危险正日趋严重。美国疾病控制中心(CDC)资料显示,截止2000年底美国医务 人员中已有57人被确诊感染了艾滋病病毒,由皮肤刺伤造成的感染48人,占84. m。而经 世界卫生组织的调查分析显示,每年因不安全的针操作而感染致命疾病的人数达210万之 多,给被感染者造成了极大的痛苦和不幸,并导致了庞大的医疗开支,加重了社会及家庭的 经济负担。据美国疾病疾控中心统计显示,使用更安全的医疗器械装置可以避免62%-68% 的锐气伤的发生,故开发出更安全的带针医疗器械产品是十分必要。目前临床上使用的头皮针由于进针前将保护套丢弃,造成其安全性能欠佳。专利 号为200420038952. 4,专利名为一次性安全型静脉输液头皮针的技术中,公开了一种 一次性安全型静脉输液头皮针,包括针头、针头针翼、保护套构成,在保护套内的端部设有 消毒棉塞,在保护套后段的壁上设 ...
【技术保护点】
1.防刺头皮针,其包括针头、针座和针帽,针座一端固定有针头,针座一侧延伸出针翼,针帽为一段中空的塑料管,套设在针座固定有针头的一端,其特征在于:所述针帽对应针翼设有导槽,所述导槽靠近针出口端和导槽末端均设有对应针翼的卡槽,导槽末端的卡槽靠近针出口端设有卡钩,该卡钩与导槽相接处向针出口端延伸出一凸起,当未进行输液时,头皮针的针翼由凸起卡置于导槽内;当进行静脉输液时,头皮针的针翼卡入导槽针出口端的卡槽;当头皮针输液完毕时,针翼卡入导槽末端设置的卡槽卡钩内。
