Abstract

本发明涉及一种配套输液器用静脉输液针的带翼(1)的连接座,属于医疗器械技术领域。本发明的特点是当翼(1)的伸展宽度L不小于连接座座体(4)底部(2)的半径R时,座体后端(3)外圆周直径不小于座体端口(5)的外圆周直径,连接座分型面位于翼(1)伸展最宽与座体(4)底部(2)之间,以便塑料在模具内注塑成型后轴向脱模。因此,模具制作时,可采用双排或多排的配件排列方式,单次注塑成型配件数量相对较多,大大提高了连接座注塑生产效率。

Description

一种翼形输液针连接座
所属技术领域
本发明涉及一种配套输液器用静脉输液针的带翼的连接座,属于医疗器械技术领域。
背景技术
常规静脉输液针连接座一般未设置突出的翼,不便于医务人员临床使用过程中将连接座与输液器接头旋紧,容易出现输液时漏液。虽然有少部分产品在连接座上设置有突出的翼,但由于连接座座体后端外圆周直径小于座体端口的外圆周直径,模具设计只能采用滑块侧面脱模,再轴向抽芯脱模的方式,配件在模具上的排列为单排,单次注塑成型配件数量少,生产效率低。
发明内容
本发明提供了一种翼形输液针连接座,它具有便于医务人员临床使用过程中将连接座与输液器接头旋紧,且该配件便于注塑成型脱模,模具制作时,可采用双排或多排的配件排列方式,单次注塑成型配件数量相对较多,大大提高了连接座注塑的生产效率。
本发明解决其技术问题所采用的技术方案是:当翼的伸展宽度L不小于连接座座体底部的半径R时,座体后端外圆周直径不小于座体端口的外圆周直径,连接座分型面为翼伸展最宽与座体底部之间,即位于A、B面之间,以便塑料在模具内注塑成型后轴向脱模。因此,模具制作时,可采用双排或多排的配件排列方式,单次注塑成型配件数量相对较多,达到了即能方便于医务人员临床使用过程中将连接座与输液器接头旋紧的结构,又大大提高了连接座注塑生产效率的目的。
本发明结构简单,模具容易制作,生产大大得到提高,且产品方便于医务人员临床使用过程中将连接座与输液器接头旋紧。
附图说明
图1是实施例的结构示意图;
图1中:1.翼,2.底部,3.座体后端,4.座体,5.座体端口
具体实施方式
下面,结合附图说明本发明的实施情况:
当翼(1)的伸展宽度L不小于连接座座体(4)底部(2)的半径R时,座体后端(3)外圆周直径不小于座体端口(5)的外圆周直径,连接座分型面位于翼(1)伸展最宽与座体(4)底部(2)之间,即位于A面与B面之间,以便塑料在模具内注塑成型后轴向脱模。因此,模具制作时,可采用双排或多排的排列方式,单次注塑成型配件数量相对较多,达到了即能方便于医务人员临床使用过程中将连接座与输液器接头旋紧的结构,又大大提高了连接座注塑生产效率的目的。
