Description

本实用新型涉及一种兽用静脉进针器,属于兽医医疗器械。

目前,兽医使用的针具已有很多,但用针具在病兽体静脉部位进行注射时,尚无结构简单,操作方便的进针器械。

中国专利申请CN87204864提出的兽用万能进针器结构复杂,无进针力度调节装置,对不同病兽进针时会出现进针不足或过度现象。

本实用新型的目的是提供一种体积小、重量轻、结构简单、操作安全、方便、进针准确,对不同病兽可调节进针力度和控制进针深度的兽用静脉进针器。

本实用新型的兽用静脉进针器,外形似手枪,其结构主要由枪管系统、持针器和板机系统组成。顶杆用于上机并直接控制进针深度,后调节螺母,可根据不同病兽,调节弹簧行程来控制进针力度,持针器后端内孔为锥度可套入枪管前端锥度杆上,持针器前端有一斜面,可倾斜紧贴病兽静脉,控制进针角度,右手持枪,在硬物上向下压顶杆、顶杆凸台被板机勾住,持针器内装入针具并套入枪管,将持针器斜面紧贴病兽静脉血管,扣动板机,即可准确进针。经加长枪管和顶杆前端长度可作成兽用三胃进针器或穴位穿刺等进针器。

本实用新型同现有技术相比,具有结构简单,使用安全、方便的优点。由于采用了装有调节弹簧行程的螺母『4』,可根据不同病兽调节进针力度,克服了经常出现的进针不足或进针过度的缺点;又由于顶杆『2』为一园柱形凸台且后有空腔的钢杆,一改通常采用的板把上机为顶压顶杆『2』上机,并由顶杆『2』直接控制进针深度;枪管前端作成锥杆,持针器后端也作成锥孔,利于装御。

本实用新型的具体结构由以下的实施例及其附图给出。

图1是根据本实用新型提出的兽用静脉进针器的剖面图。

下面结合图1详细说明提出的具体装置的细节及工作情况。

参照图1,该进针器的枪管系统由枪管『1』、顶杆『2』、弹簧『3』、螺母『4』装配而成。封闭式枪管『1』前端作成锥杆,可套入持针器『5』的后锥孔,后端装有调节弹簧行程的螺母『4』;顶杆『2』为一园柱形凸台且后有空腔的钢杆,顶杆『2』前端伸出枪管『1』的长度直接控制进针深度;枪管『1』和顶杆『2』空腔内装有弹簧『3』。

持针器『5』前端有一斜面,可紧贴病兽静脉血管控制进针角度,后端内孔为锥孔,可套在枪管『1』上,持针器『5』内装针具。

板机系统由板机『6』、勾轴『7』、弹簧『8』组成。视不同病兽,调节弹簧行程螺母『4』后,右手持枪,在硬物上顶压顶杆『2』,顶杆『2』随之后移,板机『6』扣住顶杆『2』的凸台,将持有针具的持针器『5』套入枪管『1』前端,持针器『5』前端斜面紧贴病兽静脉血管,勾动板机『6』,板机『6』在勾轴『7』作用下,脱离顶杆『2』的凸台,在弹簧『3』的作用下,顶杆『2』急速前移,推动针具准确进入兽体。

本兽用静脉进针器,除持针器『5』外,其余机件全部安装在枪身内,枪把『9』由沉头螺钉『10』固定在枪身上。
