Abstract

Hospital stretch contacts today have a strain joint, which is typically made of two plastic parts that are 'clicked' together. The joint is broken for safety reasons if the patient / user pulls hard during an alarm call. Once the joint is broken, it weakens and needs to be replaced. The invention is characterized in that the plastic joint in the drawstring is replaced by an aluminum joint, which is 'clicked' together by a magnet in each part of the joint, so that the joint is held together by magnetism. A magnetic link does not weaken over time. The invention replaces the old broken joints which do not work as intended: - The new joint is easy to disassemble and assemble (magnets look exactly together). - The new joint is easy to sterilize (the old joints are infectious spreaders, because they are typically bonded together when the knee joint no longer works). - The new joint is easy to install and replace. - Magnet assembly extends joint life. - The new link solves a major problem in hospitals and the like.

Hospital stretch contacts today have a strain joint, which is typically made of two plastic parts that are 'clicked' together. The joint is broken for safety reasons if the patient / user pulls hard during an alarm call. Once the joint is broken, it weakens and needs to be replaced. The invention is characterized in that the plastic joint in the drawstring is replaced by an aluminum joint, which is 'clicked' together by a magnet in each part of the joint, so that the joint is held together by magnetism. A magnetic link does not weaken over time. The invention replaces the old broken joints which do not work as intended:

- The new joint is easy to disassemble and assemble (magnets search precisely together).

- The new joint is easy to sterilize (the old joints are infectious spreaders, because they are typically bonded together when the knee joint no longer works).

- The new joint is easy to install and replace. - Magnet assembly extends joint life.

- The new link solves a major problem in hospitals and others.

Description.

The invention consists of a load link for mounting on a drawstring with connection to a contact, so that the patient can call for help

The loading link consists of two aluminum containers, each containing opposite neodyme magnet (2 and 3). See Figure 1

The function of the load link is to break the connection between the patient cord and the contact part (pull cord) (1). The two neodymium magnets (3), mounted in aluminum containers (2), assemble the two joints and act as an overload safety clutch.

Magnets can be varied so that the breaking strength can be changed as needed.

Advantages of this invention over prior art.

Replacement for the known mechanical break joints made of plastic, which do not work as intended, as they quickly wear out and lose tensile strength.

EP 0930630 A1 discloses a mechanical loading joint comprising two half-links with a knuckle joint.

The well-known cords and knuckle joints are infectious spreaders because they are not easily separable and have a short life.

The invention is easy to separate and assemble, as the magnets search precisely together and, as permanent magnets, have constant and uniform breaking strength.

Precisely the magnetic assembly makes separation and sterilization simple and effective and extends the life of the cord. The magnetic assemblies are easy to assemble and replace and protect the fixed installation against defects in the event of severe drag.

Elegant solution to a major problem in all hospitals.

Claims (3)

Requirements. 1. A load link mounted on a drawbar for hospital extension contacts, characterized by comprising two aluminum joints each containing one opposing magnet (1,2,3), which together holds the load link by magnetism. 2. A load link according to claim 1, characterized in that the magnets in the load link (3) are permanent neodymium magnets.
