Abstract
(EN)
A safe injection device, relating to the field of medical instruments, comprising a needle tube (1), a needle seat (2), an elastic member, a sliding block (4), a needle tip sleeve (5), a protective sleeve (6) and an outer cover (7); the needle seat (2), the elastic member, the sliding block (4), the needle tip sleeve (5) and the protective sleeve (6) are sequentially sleeved by taking the needle tube (1) as a shaft; and the sliding block (4) is configured to rotate in an irreversible manner after one use. The injection device has a simple and reasonable structure, is safe, telescopic and easy to use, avoiding the fear of a needle tip during injection when in use. After the injection device has been used, by means of the eccentric center principle, a downward pressing stroke is blocked, and the injection device cannot be completely pressed again, and at this time, the needle tip will no longer be exposed, thereby more effectively avoiding the risk of cross infection caused by accidentally touching the needle tip after use; in addition, this structure makes it difficult to return to the original position after use, thus after being used, the injection needle is safer and will not be used again, effectively avoiding cross infection. After the injection device has been used, a warning that the device has been used is given by raising the colored sliding block (4).

L'invention concerne un dispositif d'injection sûr, se rapportant au domaine des instruments médicaux, comprenant un tube d'aiguille (1), un support d'aiguille (2), un élément élastique, un bloc coulissant (4), un manchon de pointe d'aiguille (5), un manchon de protection (6) et un couvercle externe (7) ; le support d'aiguille (2), l'élément élastique, le bloc coulissant (4), le manchon de pointe d'aiguille (5) et le manchon de protection (6) sont emmanchés de manière séquentielle en prenant le tube d'aiguille (1) comme corps ; et le bloc coulissant (4) est configuré pour tourner de manière irréversible après une utilisation. Le dispositif d'injection est doté d'une structure simple et raisonnable, est sûr, télescopique et facile à utiliser, évitant de craindre la pointe de l'aiguille pendant l'injection lors de l'utilisation. Une fois que le dispositif d'injection a été utilisé, au moyen du principe de l'excentrique, la course de pression vers le bas est bloquée, le dispositif d'injection ne peut pas être complètement enfoncé à nouveau, et la pointe de l'aiguille n'est alors plus exposée, ce qui permet d'éviter efficacement le risque d'infection croisée provoquée par le contact accidentel de la pointe d'aiguille après utilisation ; en outre, cette structure rend difficile le retour à la position d'origine après utilisation, se qui fait que, après utilisation, l'aiguille d'injection est plus sécurisée et ne sera pas utilisée à nouveau, évitant efficacement une infection croisée. Une fois que le dispositif d'injection a été utilisé, un avertissement indiquant que le dispositif a été utilisé est donné par l'élévation du bloc coulissant de couleur (4).

一种安全型注射装置,涉及医疗器械领域,包括针管(1)、针座(2)、弹性件、滑块(4)、针尖套(5)、保护套(6)和外盖(7),针座(2)、弹性件、滑块(4)、针尖套(5)和保护套(6)以该针管(1)为轴依次套设;该滑块(4)被配置为在使用一次后不可逆地旋转。该注射装置结构简单合理,安全、可伸缩,使用方便,在使用过程中避免了注射时对针尖产生恐惧。使用完后通过偏心原理,阻挡下压行程,无法再次完全下压,此时针尖也不会再露出,从而更加有效的避免了使用后意外误触针尖发生交叉感染的风险,且该结构使得使用后不易再回到原待使用位置,从而使注射针头在使用后更加安全且不会二次使用,有效避免了交叉感染。该注射装置使用完毕后通过彩色的滑块(4)升起进行使用过的警示。
