DE102006035257A1 - Catheter-plug connection device for mentally retarded patients, has upper and lower plates that are connected using hinge joint, and neck that secures and encompasses outer regions of coupling and connector for connecting tube ends - Google Patents

Abstract

The device has an upper plate and a lower plate that are connected using a hinge joint. A magnet lock for an external magnet is mounted in an inner area. A neck is formed in the sides of the upper part and the lower part. The neck axially secures and encompasses outer regions of a coupling (6) and a connector (6`) for connecting tube ends (7, 8). The magnet is coated with polysulphone and polycarbonate.

Description

The The invention relates to a device for catheter connectors for connecting and securing hoses in the medical field.

A Coupling or a Y or T piece connect two or more pieces of hose. These should not be accidental, unintentional or can be dismantled by partially dumb patients.

The leads in the worst case for leakage of supply fluid, from body fluids up to serious health problems

give up This invention is a security against unauthorized opening of Clutches, or Y or T pieces to work safely and open with the keys as possible can.

To a special magnetic lock has been developed. It is relative inexpensive manufacturable and solvable with a standard magnet that the medical Personnel anyway, to secure debile patients.

Base this solution are two plastic half shells that are connected via a resilient film hinge are. In these plastic shells is in each case a cavity a known magnetic lock integrated with magnetic tongues. It reminds in the function of the magnetic locks for securing debiler Patients. Decisive for the feature is that the sides of the upper shell and in the lower shell one constriction each having the coupling or the plug or a Y or T piece laterally so that they do not pull apart. According to the invention, it is provided on the one hand to bring the magnetic lock on the side of the hinge and on the other hand, on the opposite side of the hinge, that depends on the locking force of the lock.

there can the coupling and the plug have a known snap connection or a Luer-Lock thread. Also compounds where the clutch a locking sleeve owns, can opened by debile patients become.

To open the Device according to the invention you use a standard magnet that is suitable for securing debilitated patients anyway in the medical staff is in use.

It is natural every other special magnet can be used when placed on the magnetic fields of the castle is tuned.

To the touch of the magnetic lock with the standard magnet open the magnetic Tongues within the magnetic lock and the half-shells spring through the residual elasticity of the film hinge automatically apart. Then you can the Open the coupling or the Y or T piece again.

Instead of the simple film hinge is a known from cosmetics provided with three-part hinge, which is offset by the drawstrings let the half-shells spring into the two stable layers "up" and "to". That's a significant one Increase comfort.

The Upper shell and the lower shell together with the film-like hinge as well as the serving of the magnet should be made of a heat-resistant plastic for the purpose of sterilization such as a polysulfone and / or a polycarbonate getting produced. Seals are also made of heat-resistant, made of elastic TPE, silicone or rubber.

Further embodiments of the present invention are the following examples and the 1 to 14 refer to. Showing:

1 and 2 - coupling and plug on two pieces of tubing,

3 to 6 - Coupling and plug on two pieces of hose - surrounded by a closed device with magnetic lock,

7 to 10 - Coupling and connector on two pieces of hose- surrounded by an open device with magnetic lock on the side of the hinge and with magnet,

11 to 14 - Coupling and connector on two pieces of hose- surrounded by an open device with magnetic lock opposite the hinge and with magnet.

The 1 and 2 show a clutch 6 and plugs 6 ' on two pieces of tubing 7 and 8th in the closed state.

In the 3 to 6 is this clutch 6 and the plug 6 ' mounted on two pieces of tubing 7 . 8th and without aids hardly or very difficult to solve surrounded by a closed device 10 with a magnetic lock known from fixations of debilies ago 4 ,

This device 10 has an upper shell 1 and a lower shell 2 on top of that by a springing hinge 3 are connected and in their interior 5 a magnetic lock 4 for an external magnets 14 is mounted.

In the pages 9 . 11 the upper shell 1 and in the lower shell 2 is ever a constriction 12 . 13 is formed, which is the outer areas of a clutch 6 and a plug 6 ' for connecting the hose ends 7 . 8th Secure and grip axially. Almost the constrictions 12 . 13 which could also be referred to as constrictions, like a firm hand around the otherwise easily detachable shells 1 and 2 around.

How to solve such, secured by unauthorized connection is in the 7 to 10 to see.

The coupling 6 and plugs 6 ' stuck firmly on two pieces of tubing 7 . 8th and are surrounded by an open device 10 with the magnetic lock 4 on the side of the hinge 3 and with a permanent magnet 14 to solve by putting it to the magnetic lock 4 approach leads.

The 11 to 14 illustrate the construction of open device 10 with an active hinge 3 . 3 ' . 3 '' , It works that way besides having a normal movie hinge 3 with fixed axis of rotation two outwardly and at a distance offset traction bands 3 ' . 3 '' are formed. They are easily and elastically overstretched when opening in a medium opening angle. As a result, this hinge has a labile central position and two stable end positions, in which it snaps in each case after opening or after closing.

With an external magnet 14 became the magnetic lock 4 open. The latter is opposite the active hinge 3 . 3 ' . 3 '' been formed.
