Abstract

A medical pump comprises a pumping mechanism located in a housing and a display placed on a support member which is articulated on the housing. The support member is pivotable with respect to the housing around a first axis between a folded-back position and an folded-out position. The display is pivotable with respect to the support member around a second axis between a first position, called a non pivoted position, and a second position, called a pivoted position, wherein the first axis and the second axis are parallel to each other. This allows the support member, in a first movement, to pivot around the first axis and, in a second movement, to pivot the display around the second axis. These two movements are independent from each other and it is therefore possible to perform the movements simultaneously or subsequently.

Claims

1. A medical pump, wherein a pumping mechanism located in a housing and a display placed on a support member which is articulated on the housing, the support member being pivotable with respect to the housing around a first axis between a folded-back position and an folded-out position, characterized in that the display is pivotable with respect to the support member around a second axis between a first position, called non pivoted position, and a second position, called pivoted position, wherein the first axis and the second axis are parallel to each other.

2. A medical pump according to claim 1, wherein the display is placed in a frame which is pivotable with respect to the support member in order to pivot around the second axis between the non pivoted position and the pivoted position.

3. A medical pump according to claim 1, wherein the support member is configured to rotate around the first axis from the folded-back position to the folded-out position in a direction which is opposed to the direction of rotation of the display or the frame of the display from the non pivoted position to the pivoted position.

4. A medical pump according to claim 1, wherein the support member is configured to rotate around the first axis from the folded-back position to the folded-out position in a direction which is identical to the direction of rotation of the display or the frame of the display from the non pivoted position to the pivoted position.

5. A medical pump according to claim 2, wherein the support member and the display or the frame holding the display block the access to the pumping mechanism when the support member is in the folded back position and the display or the frame is in the non pivoted position, whereas when the support member is in the folded-out position, the pumping mechanism is accessible.

6. A medical pump according to claim 2, wherein the frame is provided with a keyboard which is preferably placed aside the display.

7. A medical pump according to claim 1, wherein the support member comprises an arbor and two arms parallel to each other and perpendicular to the arbor.

8. A medical pump according to claim 1, wherein indexation means are provided for defining the privileged pivot positions of the support member with respect to the housing of the pump.

9. A medical pump according to claim 8, wherein the indexation means comprise on the one hand side a bushing fixed on the arbor and being provided with at least one depression and on the other hand side of a came provided with a projection, the came being placed in the housing of the pump and being mobile exclusively in translation parallel to the axis of the arbor and means being provided for pushing the projection of the came against the corner of the bushing provided with the depression(s).

10. A medical pump according to claim 1, wherein retaining means are provided with liberation means for preventing the display or the frame from pivoting in one direction with respect to the support member if the liberation means are not actuated.

11. A medical pump according to claim 10, wherein the retaining means comprise on the one hand side a ratched wheel fixed on the support member and on the other hand side a pawl fixed on the display or the frame of the display.

12. A medical pump according to claim 1, wherein the pump is a pump of the push-syringe type and in that the two pivot axes are parallel to the axis of a syringe placed into the pump.

13. A medical pump according to claim 1, wherein a spring is provided which is configured to keep the support member in the folded-out position if no external force is exerted on the support member.

14. A medical pump according to claim 13, wherein the pump is a peristaltic pump and in that the two pivot axes are parallel to the camshaft of the pumping mechanism.

15. A medical pump according to claim 14, wherein the display is placed in a frame which is pivotable with respect to the support member in order to pivot around the second axis between the non pivoted position and the pivoted position and that a counterplate is placed on the part of the frame directed to the pumping mechanism when the support member is in folded-back position and the frame is in the non pivoted position.

16. A medical pump according to claim 15, wherein the first axis is placed in such a way that when the display or the frame holding the display is in its non pivoted position and the support member is moving to its folded-back position, the last part of the movement of the counterplate is essentially horizontal and perpendicular to the axis.

17. A medical pump according to claim 16, wherein the first axis is placed essentially vertically bellow the place for a tubing located against the most protruding pumping finger of the pumping mechanism.

18. A medical pump according to claim 13, wherein retaining means are provided with liberation means for retaining the display or the frame holding the display in the closed position against the effect of the spring if the liberation means are not actuated.

19. A medical pump according to claim 1, wherein detecting means are provided for detecting the position of the support member or of the display with respect to the housing of the pump.
