Abstract

A medical pump includes a cuboid pump housing and a front lid that is pivotably hinged to the pump housing. The front lid includes a display, in particular a touch display, and/or operating elements. The front lid is attached to the pump housing with at least one first hinge element and at least one second hinge element. The at least one first hinge element and/or the at least one second hinge element includes or forms at least one electrical connection between the pump housing and the front lid for electrical linking and exchange of data.

First claim

What is claimed:

1. A medical pump comprising:
a pump housing that is cuboid;
a fluid pump located in the pump housing;
a front lid pivotably hinged to the pump housing; and
a display and/or operating elements provided in the front lid, wherein:
the display and/or operating elements are configured to operate the fluid pump,
the front lid is mounted to the pump housing with at least one first hinge element and at least one second hinge element, and
the at least one first hinge element and/or the at least one second hinge element each comprise or form at least one electrical connection between the pump housing and the front lid for electrical linking, supply, and exchange of data,
wherein the at least one first hinge element and/or the at least one second hinge element is configured to be electrically connected at a pump housing side with a first internal circuit board of the pump housing and at a front lid side with a second internal circuit board of the front lid,
wherein:
the at least one first hinge element is formed with a hinge bolt and a hinge sleeve, wherein the hinge sleeve comprises a hinge sleeve passage extending from a first sleeve opening to a second sleeve opening, wherein at least a portion of the hinge bolt extends inside the hinge sleeve passage from the first sleeve opening towards the second sleeve opening, and the hinge bolt is rotatable relative to the hinge sleeve on a swivel axis extending between the first sleeve opening and the second sleeve opening,
the hinge bolt comprises and an internal hinge bolt passage extending from a first bolt passage opening located adjacent to and outside the first sleeve opening to a second bolt passage opening adjacent to the second sleeve opening,
the at least one first hinge element comprises at least one single electrical conductor extending continuously and entirely through the hinge bolt passage and the hinge sleeve passage, from a first location protruding outside the first bolt passage opening and the first sleeve opening to a second location protruding outside the second bolt passage opening and the second sleeve opening, and
wherein the at least one single electrical conductor is electrically connected at the pump housing side with the first internal circuit board of the pump housing and/or at the front lid side with the second internal circuit board of the front lid.

2. The medical pump according to claim 1 , wherein the at least one first hinge element and/or the at least one second hinge element is configured for exchanging electrical potentials.

3. The medical pump according to claim 1 , wherein the at least one first hinge element is configured to transfer electrical mass potentials.

4. The medical pump according to claim 3 , wherein the at least one second hinge element is configured to transfer at least a supply voltage and at least a data signal.

5. The medical pump according to claim 4 , wherein the data signal is transferrable by modulation on the supply voltage or a carrier signal.

6. The medical pump according to claim 1 , wherein the at least one first hinge element and/or the at least one second hinge element further comprises an additional electrical conductor electrically connected with the first internal circuit board of the pump housing by at least one electrically conductive spring and/or with the second internal circuit board of the front lid by at least one further electrically conductive spring.

7. The medical pump according to claim 1 , wherein the at least one single electrical conductor is electrically connected at the front lid side with the second internal circuit board of the front lid.

8. The medical pump according to claim 1 , wherein the at least one first hinge element comprises a rotating assembly, and the at least one first hinge element and/or the at least one second hinge element further comprises an additional electrical connection comprising at least one electrically conductive spring configured to slide against the rotating assembly during pivoting of the front lid relative to the pump housing.

9. The medical pump according to claim 1 , wherein the hinge bolt is provided on the front lid, and the hinge sleeve is provided on the pump housing, and wherein the hinge bolt is rotatably supported in the hinge sleeve during pivoting of the front lid relative to the pump housing.

10. The medical pump according to claim 8 , wherein the hinge bolt comprises a portion of at least one additional electrical connection between the pump housing and the front lid, and the at least one electrically conductive spring is provided adjacent to the hinge sleeve and positioned to slide against the hinge bolt during pivoting of the front lid relative to the pump housing.

11. The medical pump according to claim 10 , wherein the at least one electrically conductive spring is positioned to slide against an outer circumference of the hinge bolt during pivoting of the front lid relative to the pump housing.

12. The medical pump according to claim 1 , wherein the hinge bolt extends along the swivel axis, and the first bolt passage opening extends radially from the swivel axis.

13. The medical pump according to claim 12 , wherein the second bolt passage opening extends axially along the swivel axis and the second bolt passage opening is located concentrically with the second sleeve opening.

14. The medical pump according to claim 1 , wherein the at least one single electrical conductor comprises a monolithic body extending entirely from the first location to the second location.
