Embodiment Construction

[0022] With reference to the accompanying drawings, figure 1 One embodiment of the present invention is shown.

[0023] Refer below figure 1 , shows a longitudinal section according to an embodiment of the present invention. The whole device is indicated by reference numeral 10 . In this embodiment, there is an outer first body part 120 , which may be formed from a plurality of parts, which cooperates with a second body part 122 . The outer first body part 120 may be provided with an opening to enable a user to see inside to determine whether the device has been expelled.

[0024] The second body part 122 is mounted coaxially within the first body part 120 for reciprocating movement. The second body part 122 houses the spring 90 and the needle 44 in a protective manner, as shown in the figures, ie, the needle 44 is not exposed. At a distal point of the second body member 122 from the front, abutment legs 124 and 126 each include an end portion 128 and 130 , respectively. ...

Abstract

A portable medicament dispensing device having a mechanism which is not susceptible to jamming for dispensing the medication to a user. The device employs a three rack system for coupling the relative motion between reciprocating body members housing the ancillary components and a barrel plunger associated with the syringe. One embodiment further provides a cap with optional needle sheath.

Description

technical field [0001] The present invention relates to a medicament dispenser, and more particularly, the present invention relates to a structure for dispensing medicaments wherein the structure has mechanically connected components so as to substantially reduce component jamming which may normally be caused by such devices. Background technique [0002] Single-use single-dose drug delivery devices are known and are commonly used to dispense drugs, such as epinephrine, to users in an emergency manner, the so-called "epi pen" being a typical example of such a device. A significant disadvantage inherent in these devices involves jamming. Existing devices typically use a spring structure for moving critical components such as the needle and the barrel that helps deliver the drug to the needle. In the event of a jam, the results could be fatal if the user fails to fix the device to function properly. In some cases, repair is not possible within the given emergency time const...
