Abstract

A manually openable clamping holder for releasably fixing a single-use medical device to a medical treatment apparatus has a sensor for detecting the position of the clamping jaws of the clamping holder. With the clamping holder, the correct equipping of a medical treatment apparatus with the appropriate single-use device can be monitored economically and with simple operation.

First claim

What is claimed is:

1. A manually openable clamping holder configured to releasably fix a single-use device to a medical treatment apparatus, the clamping holder comprising:
coacting clamping jaws, of which at least one of the clamping jaws is displaceable manually against an action of a closing element from a closed position of the clamping jaws into an opened position of the clamping jaws, with the displaceable clamping jaw having a raised area thereon; and
a micro-switch configured to detect the opened position of the clamping jaws as the clamping jaws fix the single-use device, with one of the clamping jaws having a base part that houses the micro-switch therein, and with the micro-switch having a displaceable pin that is displaced upon interaction thereof with the raised area of the displaceable clamping jaw, wherein the pushing of the pin closes an electric circuit such that the micro-switch detects the closed position of the clamping jaws.

2. The clamping holder according to claim 1 , wherein the closing element has a helical torsion spring.

3. The clamping holder according to claim 1 , wherein the single-use device is an adsorber, a dialysis filter, or an infusion bottle.

4. The clamping holder according to claim 1 , wherein the single-use device is an infusion fluid container, or a dialysis filter.

5. A dialysis device comprising:
a manually openable clamping holder configured to releasably fix a single-use device to the dialysis device, the clamping holder including
coacting clamping jaws, of which at least one of the clamping jaws is displaceable manually against an action of a closing element from a closed position of the clamping jaws into an opened position of the clamping jaws, with the displaceable clamping jaw having a raised area thereon; and
a micro-switch configured to detect the opened position of the clamping jaws as the clamping jaws fix the single-use device, with one of the clamping jaws having a base part that houses the micro-switch therein, and with the micro-switch having a displaceable pin that is displaced upon interaction thereof with the raised area of the displaceable clamping jaw, wherein the pushing of the pin closes an electric circuit such that the micro-switch detects the closed position of the clamping jaws.

6. A medical blood treatment device comprising:
a manually openable clamping holder configured to releasably fix a single-use device to the medical blood treatment device, the clamping holder including
coacting clamping jaws, of which at least one of the clamping jaws is displaceable manually against an action of a closing element from a closed position of the clamping jaws into an opened position of the clamping jaws, with the displaceable clamping jaw having a raised area thereon; and
a micro-switch configured to detect the opened position of the clamping jaws as the clamping jaws fix the single-use device, with one of the clamping jaws having a base part that houses the micro-switch therein, and with the micro-switch having a displaceable pin that is displaced upon interaction thereof with the raised area of the displaceable clamping jaw, wherein the pushing of the pin closes an electric circuit such that the micro-switch detects the closed position of the clamping jaws.

7. The medical blood treatment device according to claim 6 , wherein the medical blood treatment device is a device for adsorption therapy, a device for an infusion of medical fluids, a device for dialysis, or a device for plasmapheresis.

8. A manually openable clamping holder configured to releasably fix a single-use device to a medical treatment apparatus, the clamping holder comprising:
coacting first and second clamping jaws, the second clamping jaw being displaceable and having a raised ridge area extending longitudinally across a portion thereof wherein said area is adjacent an axis about which the second clamping jaw rotates relative to the first clamping jaw, the second clamping jaw being displaceable manually against an action of a closing element from a closed position of the first and second clamping jaws into an opened position of the first and second clamping jaws; and
a sensor configured to detect the first and second clamping jaws relative to each other as the first and second clamping jaws fix the single-use device, the sensor being a micro-switch having a displaceable pin that is pushed into the micro-switch upon interaction with the raised ridge area of the second clamping jaw so as to close an electric circuit such that the micro-switch detects the closed position of the first and second clamping jaws.

9. The clamping holder according to claim 8 , wherein the displaceable pin is displaced by the raised ridge area when the second clamping jaw is in the closed position of the first and second clamping jaws.
