Embodiment Construction

[0033] Figure 1A A perspective view of an alternative cap (10) and associated medicated device (12) according to the invention is shown. The cap includes an elongated hollow body (14) having a first open end (16) and a second closed end (18) opposite the first open end. In this embodiment, the dosing device is a disposable insulin pen comprising a reservoir (20) in which liquid insulin is stored, a piston (22) at the rear end (24) of the insulin pen, and a A hypodermic needle (not shown) at the tip of the front portion (26) from which insulin administration takes place. The hypodermic needle has a removable sheath (28) covering the needle. Along the insulin pen body and near the front, there is provided a transparent part or parts (30) through which the level of liquid insulin can be visually checked. The insulin pen may be an existing disposable insulin pen as generally available on the market provided with an existing cap which is simply discarded and replaced by the repl...

Abstract

A replaceable cap (10) for a transdermal liquid dosing device (12) such as an insulin pen is provided. The cap includes an elongate hollow body (14) with a first open end (16) which can be placed over a front part (26) of the dosing device and a second closed end (18) opposite the first end. The cap body also includes a cavity which opens into the interior (50) of the cap body and which houses a control unit (52) which includes a timer unit, a switch mechanism (56) that stands at least partially proud of the cavity so as to project into the interior of the body, and a timer display unit (58) which displays time counted by the timer unit on an outer surface of the body of the cap. The switch mechanism is engaged by abutment of a surface of the front part of the dosing device when the cap is placed on the dosing device, and released when the cap is removed from the dosing device, the engagement and / or releasing of the switch mechanism causing the timer unit to reset after the elapse of a predetermined period of time, the time since the timer unit was last reset thereby indicating the time that has elapsed since the dosing device was last used.

Description

technical field [0001] The present invention relates to replaceable caps for medicated devices, and more particularly to replaceable caps for transdermal liquid medicated devices such as insulin pens. Background technique [0002] People with insulin-dependent diabetes need to adhere to a strictly prescribed regimen of liquid insulin injections to control their diabetes. One common means of administering insulin is through a reusable transdermal liquid dosing device commonly referred to as an "insulin pen," which consists of a plastic syringe with an insulin reservoir and a cap covering the proximal end of the syringe. cap, insulin is infused from the proximal end of the syringe through the hypodermic needle. [0003] It is known from several published studies that because diabetics require multiple daily insulin injections, the injection process quickly becomes so routine that individual doses can be easily forgotten. There is often no easy and reliable way to determine -...
