Embodiment Construction

[0026] A safety syringe according to the invention is described below with reference to the drawing, which is designated as a whole by the reference numeral 100 .

[0027] The syringe 100 includes a syringe body 1 (shown in FIGS. 2 and 4 ) made of glass. The syringe body 1 is substantially cylindrical, hollow inside and has cylindrical chamber openings at the front and rear. The body 1 has at its front end a head 10 into which a needle 11 is sunk. The body 1 has at its rear end a flange 12 protruding radially therefrom for easy grasping by the user.

[0028] As shown in FIG. 3 , a plunger 2 made of rubber can axially slide in a cylindrical cavity of the syringe body 1 in a sealed manner. The plunger 2 is supported at the front end by a rod 20 made of glass or plastic. The rod 20 has at its rear end a flange 21 which is located on the outside of the syringe body 1 so as to be able to be manually manipulated by the user.

[0029] At the rear of the rod 20 there is provided a...

Abstract

A safety syringe (100) comprises a glass syringe body (1), a plunger (2) slidable inside the syringe body (1) and provided at the rear with a manually operable stem (20), an injection needle (11) mounted at the front end (10) of the syringe body (1), a sheath (3) mounted integrally on the syringe body (1), a sleeve (4) mounted slidably on the shcath to pass from a retracted use position to an advanced safety position, in which the needle (11) is protected by the sleeve (4), locking means mutually provided in the sheath and in the sleeve to lock the sleeve (4) in position when it is in the retracted use position and in the forward safety position, and operating means (22) integrally mounted with the stem (20) of the piston to cooperate with locking means (43) so as to allow movement of the sleeve (4) from the retracted use position to the advanced safety position. <IMAGE>

Description

technical field [0001] The present invention relates to a disposable glass syringe equipped with an automatic safety device protecting the needle once the injection is performed. The invention also relates to an associated security pack that can be applied to disposable glass syringes. Background technique [0002] Syringes generally include a cylindrical body opening at the rear for receiving a plunger. Instead, a needle with a hollow interior is fitted to the head of the syringe body. [0003] Due to health regulations and to avoid the spread of infectious diseases, syringes generally must be used only once and then discarded. For this reason, there is an increasing demand for disposable syringes suitable for avoiding reuse. [0004] Also, syringes generally have drawbacks from a safety standpoint. In fact, once the syringe is used, the needle is continuously exposed at the head of the syringe body, thus posing a risk of injury or accidental sticking of the needle. ...
