Description

一种骨髓穿刺针
技术领域:
本实用新型属于医疗器械技术领域,具体地讲是一种骨髓穿刺针。
背景技术:
血液病、网状内皮系统疾病、多发性骨髓瘤的诊断,某些感染性疾病进行骨髓液细菌培养或涂片查病原体,需利用骨髓穿刺针通过骨穿刺吸取骨髓的方法来完成。目前在临床上采集骨髓液,一直采用的骨髓穿刺针,包括针头、针柄和针芯。在长期的临床工作中发现其针芯在骨穿过程中容易滑脱,从而导致骨穿失败,给患者带来痛苦。
发明内容:
本实用新型的目的是提供一种在采集骨髓液时,能够防止穿刺针针芯滑脱的骨髓穿刺针。
本实用新型的技术方案是:包括针柄、针头和针芯,其特征是在针芯上端固定设有锥形铝块,在针头上设有与锥形铝块相吻合的锥形槽。
本实用新型的有益效果是:本实用新型结构简单,使用方便,在采集骨髓液时,能够防止穿刺针芯滑脱,减轻了患者的痛苦。
附图说明:
附图1为本实用新型的结构示意图。
图中1、针柄,2、针头,3、针芯,4、锥形铝块,5、锥形槽。
具体实施方式:
包括针柄1、针头2和针芯3,其特征是在针芯3上端固定设有锥形铝块4,在针头2上设有与锥形铝块4相吻合的锥形槽5。在采集骨髓液时,将针芯3刺入骨髓腔,锥形铝块4与锥形槽5牢牢卡在一起,针芯3即不易滑脱。
