Abstract

能自行排气、不会形成空气栓塞的流量指示管,属医疗器材,由管子与浮珠组成,管子透明,内有斜度,上口小,下口大,两端连接输液器滴定管两边的皮管,外有刻度,标有浮珠在相应位置时药液的流速,浮珠在管子内,游离且显眼,它可取代目前输液器上的滴定管而应用于临床中。

Description

流量指示管
技术领域  本实用新型涉及一种指示输液流量的管子,属医用医疗器械。
背景技术  目前输液器上用于指示输液流量的是一种滴定管,滴定管内有空气,使用时需用手倒置排气,麻烦,降低输液器高度时,输液器内空气可能进入病人血管,形成空气栓塞,对病人有害。
发明内容  本实用新型的目的就是提供一种不需用手倒置排气,不会形成空气栓塞的流量指示管。
本实用新型由管子与浮珠组成,管子透明,内有斜度,上口小,下口大,两端分别连接输液器滴定管两边的皮管,外有刻度,标有浮珠在相应位置时药液的流速,浮珠放在管子内,游离且显眼,管子内流速改变时,浮珠在管子内的高度即改变,对应管子外的刻度即读出药液流速,药液在管子内流动,空气自行排净,不需倒置排气,管子内不会有余下的空气,不会形成空气栓塞。
与传统的输液器滴定管相比,它用管子与浮珠来取代原来存有空气的滴定管,使之不需用手倒置排气,不出现空气栓塞。
附图说明图  1产品的结构简图
图中:1、管子  2、浮珠  3、刻度
具体实施方式  本实用新型由管子1与浮珠2组成,管子1透明,内有斜度,上口小,下口大,两端连接输液器滴定管两边的皮管,外有刻度3,标有浮珠2处于相应位置时药液的流速,浮珠2放在管子1内,游离且显眼,液体在管子1内流动时,对浮珠2有冲力,流速大,冲力也大,浮珠2离管子1上口的距离也远,看浮珠2所在的位置对应管子1外的刻度3,即可读出药液的流速。

Claims (1)

1.流量指示管由管子(1)与浮珠(2)组成,其特征在于:管子(1)透明,内有斜度,上口小,下口大,两端连接输液器滴定管两边的皮管,外有刻度(3),标有浮珠(2)在相应位置时药液的流速,浮珠(2)放在管子(1)内,游离且显眼。
