Abstract

A pump device for use in operating theatres and to arrangements composed of corresponding pump devices and endoscopes. A pump device according to the invention for use in operating theatres includes a pump unit with a pump and a control unit, and a pump hose attached to the pump unit. The pump unit further includes a light source that can be controlled by the control unit to display the operating state of the pump unit. The pump hose has a fibre optic which extends along the pump hose, wherein the first end of the fibre optic is designed to couple in light from the controllable light source. The arrangement according to the invention includes a pump device according to the invention and an endoscope, which is designed to deliver flushing liquid to the operating site.

Claims

1. A pump device for use in operating theaters, comprising a pump unit with a pump and a control unit, and a pump tube connected to the pump unit,

wherein

the pump unit comprises a light source actuatable by the control unit to display the operating state of the pump unit and the pump tube has an optical fiber extending along the pump tube, wherein the first end of the optical fiber is arranged for coupling-in light from the actuatable light source.

2. The device as claimed in claim 1,

wherein

the light source is embodied to output radiation outside of the visible range and provision is made of a conversion element for converting the radiation from the light source into visible light.

3. The device as claimed in claim 1,

wherein

the optical fiber has one or more faults for light exit between the first end and the second end.

4. The device as claimed in claim 3,

wherein

the distances between the two faults adjacent to one another in each case decrease toward the second end proceeding from the first end of the optical fiber.

5. The device as claimed in claim 1,

wherein

the light source is variable in color, the control unit being embodied to control the color change of the light source.

6. The device as claimed in claim 5,

wherein

the control apparatus is embodied to change the color of the light source in a manner dependent on the flow direction.

7. The device as claimed in claim 1,

wherein

the control apparatus is embodied to let the light source pulsate or blink depending on the flow rate.

8. The device as claimed in claim 1,

wherein

the pump apparatus has one or more sensors for monitoring operational parameters of the pump unit and/or properties of the fluid to be pumped, the control apparatus being embodied to display the measured values from the sensor or sensors by way of the light source.

9. The device as claimed in claim 1,

wherein

the optical fiber is arranged on the outer side of the pump tube, the optical fiber being adhesively bonded onto the pump tube or being coextruded with the latter, or the pump tube being a multi-lumen tube, with the optical fiber being guided through a chamber of the multi-lumen tube or being coextruded with the multi-lumen tube.

10. The device as claimed in claim 1,

wherein

the actuatable light source is arranged at the pump tube and connected to the control unit of the pump unit by means of an electric line, which extends along the pump tube in place of the optical fiber

11. An arrangement comprising a pump device and an endoscope,

wherein

the pump device as claimed in claim 1, and the embodied endoscope are embodied to supply rinsing liquid into the operating region, wherein the free end of the pump tube is connected to the endoscope for supplying rinsing liquid.
