WATER RESERVOIR FOR A DEVICE FOR GAS HUMIDIFICATION IN LAPAROSCOPY

Abstract

The present invention relates to a water reservoir for a device for gas humidification in laparoscopy with a water reservoir for connecting to a gas supply device (insufflator).

Claims

1. A device for gas humidification in laparoscopy for connecting to a gas supply device (insufflator), including a water reservoir in a plastic chamber with an optional first absorbent humidification means, wherein the plastic chamber includes a gas inlet and a gas outlet, wherein the gas inlet is connected directly or through an optional tube to the insufflator, and wherein the gas outlet leads to a gas tube, one or more substantially cylindrical humidification means made of a second absorbent material, a gas tube, through which gas can be supplied to a patient, wherein the one or more substantially cylindrical humidification means made of a second absorbent material with at least one cylindrical front face are in contact with the water reservoir, and wherein the other cylindrical front face or the cylinder barrel is positioned in the gas flow.

2. The device of claim 1, wherein the first and/or the second humidification means is made from a material, which can transport liquid by the capillary effect.

3. The device of claim 1, wherein the plastic chamber contains an access for humidifying the humidification means.

4. The device of claim 1, wherein a heated gas tube at the gas outlet of the plastic chamber.

5. The device of claim 1, wherein a temperature probe in the gas tube.

6. The device of claim 1, wherein the plastic chamber contains one to five substantially cylindrical humidification means.

7. The device of claim 1, wherein the one to five substantially cylindrical humidification means are positioned in the gas flow such that the gas flow is supplied via a cylindrical front face.

8. The device of claim 1, wherein the one to five substantially cylindrical humidification means and/or the first humidification means are heated.

9. The device of claim 1, wherein the water reservoir with the first humidification means is disposed concentrically about the gas flow.

10. The device of claim 1, wherein the gas tube is heated by a heating wire.

11. The device of claim 1, wherein that the one to five substantially cylindrical humidification means are positioned in the gas flow such that the gas flow is supplied via the cylindrical barrel surface.

Description

DESCRIPTION OF THE FIGURES

[0034] FIG. 1 shows the cross-section of a gas humidification device according to the invention with a substantially cylindrical humidification means (8), which is wrapped by a heating wire (11). The first humidification means is in a round plastic chamber that is disposed concentrically about the gas flow (arrows).

[0035] FIG. 2 shows a possible configuration for several (here: three) cylindrical humidification means (8) in the gas flow. The cylindrical humidification means (8) are disposed in parallel in the gas flow in a manner that the gas flow successively passes the cylinders.

[0036] FIG. 3 shows another possible configuration for several (here: two) cylindrical humidification means (8) in the gas flow. The cylindrical humidification means (8) are disposed at the angle of 90° relative to each other.
