Problems solved by technology

This problem means that pre-mixed formulations of multiple actives may not be suitable as these have a fixed ratio of active components which may not be changeable by the healthcare professional or user
[0006] Additional problems arise where multiple drug compound treatments are required, since many users cannot cope with having to use more than one delivery system or make the necessary precise calculations of the required dosage combinations

Embodiment Construction

[0055] The drug delivery system of the present disclosure is capable of administering a user-unsettable or fixed or predetermined dose of a second drug (secondary drug compound) from a secondary storage and from a primary storage via a single output or drug delivery interface. Variable doses of the first drug (primary drug compound). By setting the dose of the primary drug by the user, the fixed dose of the second drug can be automatically determined. In a preferred embodiment, the drug delivery interface is a needle cannula (hollow needle). Figure 1 to Figure 3 Three different embodiments of the invention are shown, each having a medicated module 4 attached to a drug delivery device 7 . Each module is preferably self-contained and provided as a sealed and sterile disposable module with attachment means 8 compatible with attachment means 9 at the distal end of device 7 . Although not shown, the medicated module may be supplied by the manufacturer in a protective sterile con...

Abstract

A common delivery system for two drugs (1, 2), the injection system having a drug delivery device (7), the drug delivery device (7) comprising a main reservoir containing a first drug (1) (11), the injection system having a secondary reservoir (5, 17, 30) containing a second drug (2), wherein the drug delivery device (7) has only one dose setter for the main reservoir (11) and automatically determines the dose of the second drug (2). Both drugs (1,2) are delivered via a single rationing interface (3, 16, 21, 31).

Description

technical field [0001] The present disclosure relates to medical devices and methods for delivering at least two medicaments from separate reservoirs using a device having only a single dispense interface. A single delivery program, initiated by the user, delivers a non-user settable dose of the second medicament and a variable settable dose of the first medicament to the patient. The agent is available in two or more reservoirs, containers, or packages, each containing individual (single drug compound) or premixed (multiple drug compounds formulated in combination) agent . The present invention may be particularly beneficial where the therapeutic response for a particular target patient population can be optimized through the control and determination of the treatment regimen. Background technique [0002] Some disease states require treatment with one or more different drugs. Some pharmaceutical compounds need to be delivered in a specific relationship to each other in ...
