Abstract

胸腔穿刺针是一种从病人胸腔中抽取积液的装置。针座(3)内设有圆柱形空腔(9),空腔(9)顶端为圆球状并与针头(5)的末端相通,针头(5)和针座(3)连铸为一体,在空腔(9)内置有单向球形阀体(8)并于空腔(9)顶端相吻合,在空腔(9)约1/3处,腔壁上设有三个等距的凸状点(4),正好将单向球形阀体(8)挡于顶端空腔(9)内。这种胸腔穿刺针不易堵塞,能准确确定穿刺针是否已进入胸腔,且一个人就可以完成全部穿刺工作。

Description

胸腔穿刺针
技术领域  本实用新型涉及一种医疗器械,具体地说是一种从病人胸腔中抽取积液的装置。
背景技术  现在医院中给患者进行胸腔穿刺用的穿刺针,都是用一个大的针头外加接一段橡胶管,在给患者进行穿刺时,需两个人才能完成工作,一名医务人员拿针头给患者穿刺,另一名医务人员拿止血钳夹住橡胶管,每抽完一次,必须有一个人用止血钳夹住橡胶管,另一人将针管拔下,将体液排掉;同时,由于针头无刻度,医务人员无法准确掌握针头的穿入深度,且针头只有一个针孔,容易堵塞,易给患者带来更大痛苦。
发明内容本实用新型的目的是提供一种不易堵塞、能准确掌握穿刺深度,且只用一个人即可完成全部穿刺工作的胸腔穿刺针。
本实用新型由针头、针头座和球形阀体组成,针头上设置有刻度标尺,且在距针尖端1厘米范围内,沿针管周围相隔120°角方向位置开三个小孔,其特征在于:针座的空腔内置有球形阀体。
本实用新型由于在针座的空腔内置有一球形阀体,将针管插在针管接口上,一人手握针头座就可以进行穿刺,穿进去后抽取积液时,球形阀体自动打开,当抽满针管拔下针管排放积液时,由于胸腔内的负压球形阀体自动关闭,积液不会回流,且由于针头上设置有刻度标尺和多孔,这样也不会使针头不易堵塞,医务人员还能准确掌握穿刺深度,即节省了工作人员,又加快了穿刺速度。
附图说明  附图为本实用新型的结构示意图。
具体实施方式  结合附图对本实用新型作进一步说明。穿刺针(5)上设置有刻度标尺(6),且在距针尖端1厘米范围内,沿针管周围相隔120°角方向位置开三个小孔(7)。针座(3)内设有圆柱形空腔(9),空腔(9)顶端为圆球状并与针头(5)的末端相通,针头(5)和针座(3)连铸为一体,在空腔(9)内置有单向球形阀体(8)并于空腔(9)顶端相吻合,在空腔(9)约1/3处,腔壁上设有三个等距的凸状点(4),正好将单向球形阀体(8)挡于顶端空腔(9)内,使单向球形阀体(8)既不会掉出,又能保持单向球形阀体(8)与空腔(9)顶端之间有一定的间隙。针座口处接有导管(2),导管(2)的另一端安有注射器接口(1)。使用时,将导管与针座相连,并将注射器插在导管的注射器接口上,一人手握针头座就可以进行穿刺,确定穿刺点后,根据患者胸壁厚度将穿刺针刺入穿刺点,根据穿刺针上的刻度标尺判断是否已进入胸腔,穿进去后抽取积液时,由于拉动针栓,球形阀体自动打开,积液被抽出,当抽满针管,拔下针管排放积液时,由于胸腔内的负压,球形阀体自动关闭,积液不会回流。
