Internal fluid connector

Abstract

A medical device is provided comprising a reservoir adapted to contain a fluid drug in an interior thereof, and a pump assembly. The pump assembly comprises a pump inlet, a pump outlet and an internal flow path arranged there between, and a fluid connector having an inlet and an outlet. The fluid connector is arranged to be operated from an initial state in which the fluid connector is arranged within the interior of the pump and an actuated state in which fluid communication is established between the interior of the reservoir and the interior of the pump assembly via the fluid connector and with the outlet of the fluid connector being arranged in the flow path of the pump assembly.

AI Technical Summary

Benefits of technology

The present invention provides a skin mountable drug delivery device that is convenient, cost-effective, and easy to use. The device includes a reservoir for containing a fluid drug and a pump assembly with a built-in actuatable means for connecting the pump assembly to the reservoir. The pump assembly includes a pump inlet, a pump outlet, and an internal flow path. The device also includes a fluid connector with seals that can be penetrated by a pointed end for easy sterilization. The device can be used with various types of pumps and can be adapted for different applications. The invention also provides a medical assembly comprising a medical device and a transcutaneous device unit for easy and secure application to the skin of a subject. The transcutaneous device has a pointed end for penetrating the skin and is in fluid communication with the pump outlet.

Problems solved by technology

The first class comprises infusion pumps which are relatively expensive pumps intended for 34 years use, for which reason the initial cost for such a pump often is a barrier to this type of therapy.

Although it can be expected that the above described second class of fully or partly disposable infusion devices can be manufactured considerably cheaper than the traditional durable infusion pump, they are still believed to be too expensive to be used as a real alternative to traditional infusion pumps for use on an every-day basis.
