Abstract

本实用新型涉及一种带有侧微孔的注射针。主要目的是减少在注射时,针尖给病人带来的痛苦感。该注射针头的针尖的一侧面壁上开有注液孔,而在针尖的另一侧面与注液孔相对的位置开有与内部相通的侧微孔。该注射针在注射过程中,在病人体内的局部压力减小,可减少病人的痛苦感,且针尖不会折断,使用安全可靠。

Description

一种带有侧微孔的注射针
技术领域
本使用新型涉及医用领域的一种注射针,具体的说是一种带有侧微孔的注射针。 
背景技术
目前,医用注射针头常用规格有5#、6#、7#、8#、12#、16#各种型号的,而这些型号的注射针头多为斜面单孔,注射时局部组织承受的压强大,容易产生疼痛,病人有痛苦感,当注射切割皮肤时,来自由肌肉组织的本能反应,肌肉就会夹紧针头,启针时给病人带来痛苦感,有时甚至会折针。 
发明内容
为了减少注射针在注射时,针尖给病人带来的痛苦感,本使用新型提供一种带有侧微孔的注射针。该注射针在注射过程中,在病人体内的局部压力减小,可减少给病人带来的痛苦感,针尖不会折断。 
本实用新型的技术方案是:一种带有侧微孔的注射针,包括注射针头,注射针头的针尖的一侧面壁上开有注液孔,在所述针尖的另一侧面与注液孔相对的位置开有与内部相通的侧微孔,且距针尖三分之一范围内的针壁上开有若干均布的孔。 
本实用新型与常用的注射针相比具有如下有益效果:由于采用上述技术方案,在现有的注射针头前端的锥段上开有与注液孔相对且与内部相通的侧微孔,且距针尖三分之一范围内的针壁上开有若干均布的孔,这样在注射时,针尖周围有药液填充,注射压力分布到注液孔与侧微孔上以及针身上均布的一排排孔上,局部压力降低,病人的疼痛感就会减轻,针尖就不会被肌肉夹的过紧,也不会折针。 
附图说明
图1为本实用新型的结构示意图 
图2为图本实用新型的半剖视图;
图3为图1的右视图。 
图中1-注射针头,2-针尖,3-注液孔,4-侧微孔,5-孔。 
具体实施方式
下面结合附图对本实用新型作进一步说明: 
由图1至图3所示,带有侧微孔的注射针包括注射针头1,注射针头1的针尖2的一侧面壁上开有注液孔3,而在针尖2的另一侧面与注液孔3相对的位置开有与内部相通的侧微孔4,侧微孔4可为1至3个。此外,在距针尖2三分之一范围内的针壁上开有若干均布的孔5。该注射针是在现有的注射针头1上做了上述改进,这样在静脉注射及肌肉注射时,针尖2周围有药液填充,注射压力分布到注液孔3与侧微孔4上以及针身上均布的一排排孔5上,局部压力降低,病人的疼痛感就会减轻,针尖就不会被肌肉夹的过紧,也不会折针。
