TECHNICAL FIELD

The present invention generally relates to a universal interface for an infusion system. Specifically it relates to a new carrier system for an infusion system with improved wearing comfort and handling.

BACKGROUND

Medical devices that pump medication into an individual is known and commonly used in the medical industry. Typically the medication that is delivered from such medical devices depends on the medical condition that is sought to be treated. For example, it is getting increasingly common to deliver insulin using an insulin pump to treat a diabetic patient.

Typically, the medical pump devices use a reservoir or a cartridge that contains the medicine to be delivered. Due to miniaturization of products there is an expectation that such infusion systems that carry the medication would be smaller thereby making the ability to wear and operate the system more discreet. As different users would like to hide the infusion system in different places, it is important to provide an interface that will allow a user this flexibility.

Therefore there is a need in the industry to design a an interface where the infusion system can be properly carried by the user, does not hinder in the proper operation of the infusion device and is comfortable for carrying on the body of the user.

SUMMARY

It is against the above background that the present invention proves certain unobvious advantages and advancements over the prior art.

DETAILED DESCRIPTION

The following description of the preferred embodiment is merely exemplary in nature and is in no way intended to limit the invention or its application or uses.

The present invention generally relates to a small size infusion system to be carried on the body of a user using an interface that allows for an increased comfort of carrying the infusion system and for discreet operation of the infusion system.

Referring in particular to FIG. 1, an infusion system is generally shown. The infusion system comprises an infusion pump or a unit 2, a tube or a catheter 12, and an infusion set 13. As shown, the infusion pump 12 is connected to the infusion set 13 via the tube 12. Although not shown in the drawing, the infusion pump 2 comprises a fluid storing device and the medication is delivered from the fluid storing device through the infusion set 13.

Although not expressly shown in the figures, the infusion pump 2 has at least one control to control the infusion of medication from fluid storing means. Alternatively, the infusion pump 2 may have display and controls or be void of both display and controls. Although not shown in the drawings the infusion pump 2 may be controlled remotely to dispense medication using a remote control device such as a smart phone, a PDA or any other mobile devices. Although not specifically mentioned, the infusion pump 120 may be a one time use pump such that after the dispensing of the medication the pump is disposed.

In accordance with this invention, there are 3 possibilities to carry the infusion pump close to the body: directly stick the infusion pump on the skin using a carrier system such as a patch clip, wear it with different textile carrying systems or integrate it in clothes.

In order to give maximum flexibility to the users, different carrying systems need to be optimized for different everyday situations (Sport, Office, Driving, etc). Since it is not possible to expect a user to exchange a carrier system depending on the activity they are engaged in, it is important to design an universal easy (dis)connectable interface between the infusion pump and the different carrying systems (patch clip, textile carrying and integrated in clothes systems).

Multi-wearability of the interface signifies different ways in which the infusion pump can be carried. For example, the infusion pump may be carried in a conventional way, or to adhere the pump on directly on the skin or to carry it with ergonomic textile carrying systems or to integrate it in the everyday clothes. In order to have an interface, the infusion pump may have a mechanical durable part for example a press button 6 as shown in FIG. 4 is integrated in the infusion pump housing to connect the infusion pump to different carrying systems.

In order to achieve connectibility with different carrying systems it's necessary to separate these the pump 2 from the infusion set 13. The disposable insulin path has the unique function to transport insulin as in conventional actual insulin pumps. A conventional fluid path (reservoir-catheter 12-canula) is appropriate to separate the infusion site from the carrying site of the infusion pump and permits the multiwearability of the interface.

The preferred solution to allow multiwearability is to use a conventional fluid path containing a reservoir in the infusion pump and a catheter or tube (12) which connects the reservoir with the canula in the infusion set head (13) as shown in FIGS. 1 and 2. This configuration permits to separate the fluid path/canula-skin connection of the carrying system-fluid path/canula connection.

A carrier is an element of the infusion System which attaches or joins the infusion unit (2) to a carrying system. As shown in FIG. 4, preferably, the infusion unit 2 is provided with a mechanical attachment such as press button (6) which is integrated into the infusion unit (2) so as not protrude out of the housing of the infusion unit (2). This mechanical attachment permits to fix the infusion unit (2) on 2 different types of carriers: Elastic textile carrier (1) and Patch clip carrier (10). The elastic textile carrier (1) is fixed on different textile carrying systems, could be attached with a small hanger (FIG. 16) to a bra or a neckband (FIG. 15) or ironed (FIG. 17, FIG. 18) with an adhesive surface on clothes. The patch clip carrier (10) is fixed on a plaster or adhesive.

Elastic Textile Carrier

The elastic textile carrier (1) is made of a textile or plastic flexible base (4) on which is attached an elastic belt (3) through which the infusion unit (2)can be slided (FIG. 1). The press button with ribbon (5) (female part) locks the press button (6) (male part) on the infusion unit (2).

A textile or plastic hanger (FIG. 16) could be attached at the elastic textile carrier to suspend the infusion unit (2) from a bra, a neckband (FIG. 15) or other accessories. This hanger (FIG. 16) could be opened/closed and adjusted in length with a press button, a Velcro or any other fastener.

On the backside of the elastic textile carrier (1) could additionally include an adhesive coating paste covered with a protective film (FIG. 18). In this configuration the elastic textile carrier (1) could be stuck on clothes with heat (ironing for example) which allows the adhesive coating paste to smelt and stick.

Patch Clip Carrier

The patch clip carrier (10) is stuck on skin with a plaster and therefore has a more rigid structure compared to the elastic textile holder (1). The infusion unit (2)is slided with a rail in this structure and fixed with the same sort of press button as for the elastic textile holder (1). The plaster is attached on the backside of the patch clip carrier. This configuration is called double patch (FIG. 7) because the infusion unit (2) and the infusion set head (13) are both stuck on the skin.

Carrying Systems

As shown in the figures the are several types of carrying systems. For example, one such carrying system is a Double Patch system (FIG. 3, FIG. 7) which consists of sticking the infusion unit (2) onto the body. Textile carrying systems (FIG. 1) are worn under clothes and clothes-integrated carrying systems (FIG. 2) are adhered (FIG. 17, FIG. 18) or attached (FIG. 16) on clothes.

Textile Carrying Systems (FIG. 1)
