FIELD: medicine. ^ SUBSTANCE: group of inventions refers to medical equipment and aims at injection of an active pharmaceutical component. All versions of said device contain retainers for prevention of medicine loss before injection. The first and second versions of the device comprise a case wherein there is a sectioned needle travelling along the central advance axis (X-X). The medicine is supplied to the needle. In the first and third versions of the device, the retainers are placed on the walkway of the needle. The needle is deformed with respect to the central advance axis (X-X) in the injection device when it passes through the retainers. In the second and fourth versions of the device, the retainers comprise an elastic flange ledge which when in rest seals the needle and is taken back when the needle advances. ^ EFFECT: reduced risk of implant fall-out during storage and transportation of the injection device to an injection place. ^ 50 cl, 4 dwg |
