Abstract

本实用新型涉及一种一次性使用麻醉导管。目前，市场上使用的进口导管价格昂贵，且由于喷药孔在前端、易堵塞，在制作弹簧丝时金属芯棒的摩擦屑在药剂中形成污染而不能使用，国产的导管塑料制作成型，无定型弹簧，并随着气候变化，有时太硬而损伤患者造成事故，有时太软易折不能到达指定位置，而不能使用。本实用新型中将喷药孔设计在前端侧面且斜向导管运动反方向，将弹簧丝设计在管壁中间，从而克服了目前导管的缺点。本实用新型具有柔软度适中，喷药剂阻力小、易渗散、无污染、造价低等优点。

Description

一次性使用麻醉导管
所属技术领域
本实用新型涉及一种一次性使用麻醉导管，适用于医疗用人体麻醉领域。
背景技术
当前，市场上一般使用的麻醉导管，进口产品价格昂贵，且出剂口在前顶端、易堵塞，金属弹簧丝与麻醉剂接触，易形成杂物。国产导管中无弹簧，其导管软硬度受温度影响极大，有时太硬损伤肌体、有时太软形成曲折不能到达指定位置。给麻醉医师带来极大不便，严重的还带来医疗事故，本实用新型克服了上述缺点。
发明内容
本实用新型的目的在于提供一种一次性使用麻醉导管。
本实用新型是通过以下技术方案实施的，它包括管壁、弹簧丝、喷药孔、观察窗、药剂孔等构成。
喷药孔设计成斜向导管运动反方向，弹簧丝设计置在管壁中间。
有益效果
本实用新型具有柔软度适中、置管方便、喷药剂阻力小、易渗散、无污染、造价低、无血肿、无软组织损伤等优点。
下面结合附图对本实用新型作进一步说明
附图1为本实用新型结构示意图。
附图2为附图1中的A-A向剖视图。
附图中，1为导管头部、2为喷药孔、3为柔软头、4为弹簧丝、5为管壁、6为观察窗、7为药剂孔。
如附图所示，弹簧丝4设置在管壁5中间，药剂不与弹簧丝5接触，药剂不受金属屑的污染，喷药孔2设计成斜向导管运动反方向，减少喷药的阻力，且容易使药剂渗散开。
具体实施例
取本实用新型所设计的导管一根，在特定的装置下将导管头部刺入人体，由于弹簧丝4有适当软硬度，使得整个导管进入人体指定位置，推动注射器，将药剂经过药剂孔7流入到喷药孔2喷入人体，由于喷药孔2是沿柔软头1运动反方向设置，所以喷药孔2不易被堵塞，且能顺利让药剂喷出扩散。同时由于弹簧丝4设置在管壁5中间，不出现弹簧丝4的自身相摩而产生金属屑污染药剂，且弹簧丝4的软硬度适中，使得导管不会出现弯折、太硬的现象，从而避免了医疗事故的出现，方便了麻醉师，造福了患者。
