Description

一种通用安全护套 A universal safety shield

技术领域 FIELD

[0001] 本发明涉及一种医疗注射针具安全保护装置,具体涉及一种可注射针、采血针、配药针、冲洗针等医用针类的通用安全护套。 [0001] The present invention relates to a medical needle having a safety device, particularly relates to a universal safety shield an injectable needles, blood collection needles, dispensing needles, needles and other medical needle flush class.

背景技术 Background technique

[0002] 注射针、采血针、配药针、冲洗针等医用针类在使用完毕后,大都数人都会随手丢弃,由于传统的注射针、采血针、配药针、冲洗针等医用针类没有安全保护装置,清理废弃物和回收时,常会受到针扎的伤害,存在交叉感染的风险。 [0002] needle, blood collection needles, dispensing needle, irrigation needles and other medical needle class after use, most of the several people will readily discarded due to the conventional injection needles, blood collection needles, dispensing needle, irrigation needles and other medical needle type without security when protection devices, cleaning up waste and recycling, often suffer needlestick injuries, there is a risk of cross-infection.

[0003] 为此,中国专利文献CN103285458A公开了一种安全保护套,其由连接座和侧开保护套组成,连接座为内腔与针座相配的管状构件,侧开保护套设有连接座及针管容置腔,侧开保护套的下端与连接座可转动铰接,连接座可转动至连接座及针管容置腔中,针管容置腔的侧面及下端开口,连接座及针管容置腔中设有直立的倒勾板,连接座及针管容置腔两相对的侧壁与连接座之间设有相互卡扣机构。 [0003] To this end, Chinese patent CN103285458A discloses a safety guard, which is connected to the base and the side opening protective cover, which connects the base of the tubular member and the lumen of the needle holder matching, the protective sleeve is provided with side opening connecting base and the needle accommodating chamber side opening protective sleeve lower end and the connector holder rotatably hingedly connected to the seat can be rotated to the connector holder and the needle receiving chamber, the side surface and the lower end of the needle receiving chamber opening, the connecting base and the needle receiving chamber barbed upstanding plate is provided, each provided with snap connection means between the seat and the needle cannula receiving chamber with two opposite side walls connecting base.

[0004] 在上述专利文献所述的安全保护套中,针管使用完毕后,旋转套设在针座上的侧开保护套,使针管部分置于侧开保护套的针管容置腔中,且侧开保护套与针管连接座上的卡扣机构相互扣合,从而将针管锁定在针管容置腔内,进而防止使用过后的针头意外伤人和污染环境。 [0004] In the safety guard described in Patent Document, the rear needle after use, the rotary sleeve provided on side of the needle seat to open the protective sleeve, the needle tube portion disposed side opening protective cover needle accommodating chamber, and side guard and locking mechanism of the needle tube connecting base engaging each other, so as to lock the needle retention chamber in the syringe, thereby preventing accidental needle injuries after the use and environmental pollution. 但是上述专利文献所述的安全保护套存在以下不足之处:在该安全保护套中,侧开保护套的下端与连接座可转动铰接,这样当针管容置腔将针管锁定时,侧开保护套的上端、侧开保护套的下端以及连接座之间会形成三角形结构,致使使用后的针管占用空间较大,不利于针管的回收放置;而且,如图1所示,针管容置腔在锁定针管的同时将针座和连接座也收纳在其内,从而增加了针管容置腔的体积,进而也增加了侧开保护套的总体面积,导致原材料使用量增加,产品的生产成本提高。 However, the presence of the above-described Patent Document security cover the following shortcomings: the security sleeve, side opening protective sleeve lower end and the connector holder rotatably hinged, such that when the needle receiving lumen needle tube locking, Side Protection the upper end of the sleeve, the opening side of a triangular structure formed between the lower end of the protective sleeve and the connecting seat, the needle cannula so that the use of space is large, the recovery is not conducive to placement of the needle tube; Further, as shown, the needle tube accommodated in a chamber locking needle while the needle hub and connecting base is also stored therein, thereby increasing the volume of the needle accommodating chamber, and further increases the side opening guard general area, result in increased use of raw materials, production costs increase.
