Abstract

The present invention relates to improvements on automatic injection devices, in particular for self-administered drug therapies, providing for a high degree of internal stability of the syringe and, therefore, of the associated needle, thanks to a series of elastic wasp-waisted elements and a mobile tip made of a transparent material in the preferred embodiment, which besides enabling the regulation of the length of projection of the needle during the injection also allows the user to see the exact spot where the needle will enter the flesh.

Claims

AMENDED CLAIMS[received by the International Bureau on 2 February 1998 (02.02.98); original claims 1-5 replaced by new claims 1-3 (1 page)]
1. Improvements on automatic injection devices comprising an outer barrel divided into two sections, which are screwed together when in use, and, when the spring drive member (3) housed in the rear section (1) is loaded, the forward section (2) containing the syringe (7) may be upturned and introduced forward end first into the rear section (1) , the improvements being characterized in that the rear section (1) is both kept in this position, compared to the forward section (2) , and protected by means of a cap (9) provided with a catch (9) .
2. Improvements on automatic infection devices according to which in the forward section (2) of the outer barrel there is a sliding sleeve (12) which houses the syringe (7) , the housing being characterised in that it consists of a set of moderately elastic platelike elements (11) , made of plastic or the like, whose longitudinal section is wasp- waisted so as to hold the syringe (7) firmly in the correct position and enable the extraction of the needle protection
(13) .
3. Improvements on automatic injection devices, featuring an adjustable tip (Iβ) at the forward end of the forward section (2) of the barrel, whose length may be regulated with known means, thus enabling the regulation of the length of the needle-point (13) projecting from the tip during the injection, the tip being characterized in that it is made of a transparent material , so that the patient may see the exact spot where the needle (13) will enter the flesh.
