Abstract

本发明公开了一种能够及时提醒更换液体或拔掉输液针的输液报警器。一种在输液时用的报警器,包括有弹簧秤,弹簧秤由拉环、圆形刻度盘、弹簧、吊钩、指针组成,所述圆形刻度盘上设有刻度孔,刻度孔内插有刻度插头,刻度插头为倒L形,静触点绝缘连接在刻度插头的上端,指针外端绝缘连接有动触点,动触点和静触点相对设置。所述动触点和静触点与报警器电连接。所述动触点和静触点与呼叫器电连接。当瓶内液体输完时,动触点和静触点相接触,报警器或呼叫器接通,可以及时提醒陪护、护士或病人更换液体或拔掉输液针。

Description

一种在输液时用的报警器
技术领域
本发明涉及报警装置,特别是一种在输液时用的报警器。
背景技术
病人在输液时,需要陪护、护士或病人自己经常查看输液瓶内的液体还有多少,根据液体的多少决定是否需要更换液体或拔掉输液针。有时由于查看不及时,尤其是深夜输液时,陪护、护士或病人容易出现打瞌睡现象,瓶子内没有液体的情况下,当液体在输液管内下行到一定的高度时候,由于血管内的压力和输液管内的压力平衡,输液会自动停止,此时输液器内的液面位于输液器上的滴壶下面,还经常出现回血现象。更换液体时,需要将滴壶下面的空气排出气,再进行输液,给输液带来不必要的麻烦。
发明内容
本发明解决的技术问题是提供一种能够及时提醒更换液体或拔掉输液针的输液报警器。
一种在输液时用的报警器,包括有弹簧秤,弹簧秤由拉环、圆形刻度盘、弹簧、吊钩、指针组成,所述圆形刻度盘上设有刻度孔,刻度孔内插有刻度插头,刻度插头为倒L形,静触点绝缘连接在刻度插头的上端,指针外端绝缘连接有动触点,动触点和静触点相对设置。
所述动触点和静触点与报警器电连接。
所述动触点和静触点与呼叫器电连接。
所述圆形刻度盘上排列有2-4个刻度孔。
所述圆形刻度盘上排列有3个刻度孔。
本发明的技术效果是,输液时,将输液瓶挂在拉钩上,将静触点设在与该输液瓶相配的刻度孔内,当输液瓶内液体减少时,在弹簧的作用下,指针顺时针转动方向转动,当瓶内液体输完时,动触点和静触点相接触,报警器或呼叫器接通,可以及时提醒陪护、护士或病人更换液体或拔掉输液针。
附图说明
图1为本发明的结构示意图。
图2为本发明不带刻度插头的结构示意图。
图3为本发明的刻度插头结构示意图。
具体实施方式
结合附图对本发明作进一步详细说明,本发明包括包括有弹簧秤,弹簧秤由拉环、圆形刻度盘2、弹簧、吊钩6、指针组成,所述圆形刻度盘2上设有刻度孔1,刻度孔1内插有刻度插头5,刻度插头5为倒L形,静触点4绝缘连接在刻度插头5的上端,指针外端绝缘连接有动触点3,动触点3和静触点4相对设置,所述动触点3和静触点4与报警器7电连接。报警器可以为蜂鸣器。动触点3和静触点4也可以与其它能起提醒作用的装置连接,比如,动触点3和静触点4可以作为收音机开关使用。
为能充分发挥医院现有的呼叫器作用,所述动触点3和静触点4与呼叫器电连接。
输液瓶的规格一般情况下为100ml、250ml、500ml,也有些特殊的,比如人血白蛋白是50ml的,根据输液瓶规格在所述圆形刻度盘2上排列有2-4个刻度孔。。
经常用的输液瓶规格为100ml、250ml、500ml,为方便输液,在所述圆形刻度盘2上排列有3个刻度孔,对应100ml、250ml、500ml的输液瓶。
输液时,将刻度插头5插在与输液瓶相对应的刻度孔1内,输液瓶内的液体在输液过程中不断减少,弹簧随着重量的减少向上收缩,当动触头3和静触头4相接触时,报警器7或呼叫器接通报警或呼叫,提醒陪护、护士或病人更换液体或拔掉输液针。
