Problems solved by technology

Additionally, ensuring sterility prior to use can also be an issue when using these injection devices
Although automated injection devices facilitate self-injection by patients, all of the above disadvantages lead to high costs and increased risk of user error

Embodiment Construction

[0047] Referring to the drawings, an injection device 2 according to an embodiment of the present invention includes a housing 3 having a base 3a and a cover 3b. The base 3a includes a syringe holder 12 for placing the syringe 1 therein. The syringe 1 may be of a standard type widely used for manual percutaneous injection of liquid medicines. Such transdermal injection may include, for example, subcutaneous injection. The syringe 1 comprises a needle 7, a barrel 10 (possibly a glass barrel) with a flange 11, a plunger 9 for forcing liquid through the needle, and a needle cap 8 for covering the needle when the syringe is not in use.

[0048] The syringe holder 12 has a shape that allows the syringe 1 to be inserted into the base 3a, the shape of the holder being configured to conform to the shape of the syringe with a certain clearance so as to allow easy insertion of the syringe into the holder in the correct orientation. In particular, given the shape, size and position of ...

Abstract

An injection device (2) comprising a housing (3), a syringe cradle (12) for removably receiving a syringe (1) having a needle (7), a container (10) with a flange (11), a plunger (9) and a removable needle cap (8) in the housing, and a system for performing automated injection comprising: a cap actuation mechanism (4) for gripping, storing and retrieving the needle cap, a syringe actuation mechanism (5) for moving the syringe in an injection direction (Id) from a position where the needle is inside the housing to an injection position where the needle projects out of a needle port of the housing on a skin contact face of the housing, and a plunger actuation mechanism (6) for advancing the plunger for administration of the liquid drug.

Description

[0001] field of invention [0002] The invention relates to an automatic injection device. Background technique [0003] Many medications are contained in manually actuated syringes (prefilled syringes) that include a container with a needle and a plunger rod to expel the medication. An advantage of such standard prefilled syringes is their wide availability and the wide range of drugs that can be accommodated in such syringes. However, manually actuating the syringe is often uncomfortable or difficult for some patients, and there are also safety risks associated with the needle cap not being properly replaced on the needle after the syringe has been used. [0004] To provide an alternative and increase the ease of administering liquid medications to patients, automated or automatic injection devices have become very popular. Automated injection devices are generally easier to operate by untrained individuals, such as patients. However, such automatic injection devices typi...
