Abstract

Medical device having a detachable cover element A medical device ( 1 ) for administering a medical solution to a patient comprises a housing ( 10 ), a receptacle ( 12 ) for receiving a pumping apparatus ( 3 ) for administering the medical solution to the patient, and a cover element ( 2 ) for covering the receptacle ( 12 ). The cover element ( 2 ), in a connected state, is pivotably connected to the housing ( 10 ) about a pivot axis (P) by means of a hinge connection, the hinge connection being releasable for detaching the cover element ( 2 ) from the housing ( 10 ). In this way a medical device is provided which may have an increased adjustability for use in different environments in a healthcare environment.

First claim

The invention claimed is:

1. A medical device for administering a medical solution to a patient, comprising:
a housing;
a receptacle for receiving a pumping apparatus for administering the medical solution to the patient;
a cover element for covering the receptacle,
wherein the cover element, in a connected state, is pivotably connected via a hinge connection to the housing to pivot about a pivot axis, the hinge connection being releasable for detaching the cover element from the housing; and
a blocking device disposed at the pivot axis, the blocking device for blocking, in the connected state of the cover element, movement of the cover element directed along the pivot axis with respect to the housing to detach the cover element from the housing,
wherein the blocking device comprises a blocking pin displaceably arranged on one of the housing and the cover element transverse to the pivot axis, the blocking pin being configured to interact with a blocking element arranged on the other of the housing and the cover element for blocking a movement of the cover element with respect to the housing opposite to an insertion direction directed along the pivot axis.

2. The medical device according to claim 1 , wherein the hinge connection is formed by at least one hinge device configured to pivotably connect the cover element to the housing.

3. The medical device according to claim 2 , wherein the at least one hinge device comprises a hinge pin arranged on one of the cover element and the housing and a pin receptacle arranged on the other of the cover element and the housing, the pin receptacle being configured to pivotably receive the hinge pin.

4. The medical device according to claim 3 , wherein the hinge pin is insertable into the pin receptacle in the insertion direction directed along the pivot axis for establishing the hinge connection.

5. The medical device according to claim 4 , wherein a first hinge device of the hinge connection comprises a first hinge pin, and a second hinge device of the hinge connection comprises a second hinge pin, wherein the first hinge pin and the second hinge pin are configured such that, when connecting the cover element to the housing, the first hinge pin of the first hinge device comes into engagement with an associated first pin receptacle prior to the second hinge pin of the second hinge device coming into engagement with an associated second pin receptacle.

6. The medical device according to claim 3 , further comprising a sensor device for detecting whether the hinge pin is received in the pin receptacle.

7. The medical device according to claim 6 , wherein the sensor device comprises a movable lever configured to interact with the hinge pin when inserting the hinge pin into the pin receptacle.

8. The medical device according to claim 2 , wherein the at least one hinge device comprises a damping element for damping a pivoting movement of the cover element with respect to the housing.

9. The medical device according to claim 1 , wherein the blocking pin and/or the blocking element comprise a run-up slope configured to cause a displacement of the blocking pin for enabling the connecting of the cover element to the housing and/or the releasing of the cover element from the housing.

10. The medical device according to claim 1 , wherein the cover element comprises a lock element for locking the cover element with the housing when the cover element is connected to the housing and is closed for covering the receptacle.

11. The medical device according to claim 1 , wherein the cover element comprises a cover body formed from a transparent material.

12. The medical device according to claim 1 , further comprising a control device constituted to evaluate whether the cover element is connected to the housing and is closed for covering the receptacle in order to enable an administration operation dependent on the evaluation.

13. A medical device for administering a medical solution to a patient, comprising:
a housing;
a receptacle for receiving a pumping apparatus for administering the medical solution to the patient;
a cover element for covering the receptacle,
the cover element, in a connected state, being pivotably connected to the housing about a pivot axis by means of a hinge connection, the hinge connection being releasable for detaching the cover element from the housing,
the hinge connection being formed by at least one hinge device configured to pivotably connect the cover element to the housing,
the at least one hinge device comprising a hinge pin arranged on one of the cover element and the housing and a pin receptacle arranged on the other of the cover element and the housing, the pin receptacle being configured to pivotably receive the hinge pin, and
a sensor device for detecting whether the hinge pin is received in the pin receptacle.

14. The medical device according to claim 13 , wherein the sensor device comprises a movable lever configured to interact with the hinge pin when inserting the hinge pin into the pin receptacle.
