Abstract

Shown and described is a user unit (1) for determining output parameters from respiratory gas analyses, particularly for use in spiroergometry devices, with a preferably replaceable breathing tube (2) and a housing part (3), wherein the breathing tube (2), also preferably, can be inserted into the housing part (3) in order to put the user unit into a measuring mode. A provision is made according to the invention that a nose clip (4) connected to the housing part (3) and designed to seal the nose of a user (5) during the determination of the output parameters is provided on the top side of the housing part (3).

Claims

1. A user unit for determining output parameters from respiratory gas analyses, particularly for use in spiroergometry devices, with a preferably replaceable breathing tube and a housing part, wherein the breathing tube, also preferably, can be inserted into the housing part in order to put the user unit into a measuring mode, characterized in that a nose clip connected to the housing part (3) and designed to seal the nose of a user during the determination of the output parameters is provided on the top side of the housing part and a chin rest connected to the housing part and designed to rest against the chin of a user during the determination of the output parameters is provided on the bottom side of the housing part, wherein the nose clip is mounted on the housing part such that it can be depth-adjusted in the axial direction of the breathing tube and fixed at various points on the housing part and wherein the chin rest is mounted on the housing part such that it can be depth-adjusted in the axial direction of the breathing tube and fixed at various points on the housing part.

2. The user unit as set forth in claim 1, wherein after the insertion of the breathing tube into a test subject'"'"'s mouth, the housing part can be held on the test subject'"'"'s head merely by means of the nose clip and the breathing tube and Supported on the test subject'"'"'s chin by means of the chin rest.

3. The user unit as set forth in claim 1, wherein the nose clip has a substantially U-shaped clamping bracket with two clamping arms, wherein the two clamping arms are angled in an L shape at the free ends and wherein a clamping area for insertion of the nose that is open to the side of a mouthpiece of the breathing tube is formed between the angled ends.

4. The user unit as set forth in claim 1, wherein each clamping arm has at its angled end a clamp roller that can be rotated about the longitudinal axis (X₂) of the clamping arm, the clamping area being formed between the clamp rollers.

5. The user unit as set forth in claim 1, wherein a cylindrical roller body that is mounted such that it can rotate about the longitudinal axis (X₂) of the clamping arm is provided for the clamp roller on the angled end of the clamping arm, the clamp roller having a central opening for placement onto the roller body and, preferably, being movable on the roller body in the axial direction.

9. The user unit as set forth in claim 1, wherein at least one guide projection and/or a guide slot is provided on the housing part and/or on the screw head to guide the support arms.

11. The user unit as set forth in claim 1, wherein the chin rest has a substantially U-shaped bracket with two support arms, the two support arms being bent in an L shape and connected to the housing part.
