Diagnostic probe and kit for tonometric examination of respiratory insufficiency and regional perfusion failure of the body
First Claim
1. A tonometric device (20) for examination of respiratory insufficiency and regional tissue perfusion failure in patients comprising:
- a distal end (22) for introducing into the gastrointestinal tract of the body of a patient,a section (24) introduced into the body, anda section (3) for fixing the position of the device to the patient,wherein the section to be introduced (24) comprises;
a first tube (1) to which an additional tubing (4) is connected,a second tube (2) arranged substantially parallel with and fixed to the first tube (1), wherein the distal end (22) of the second tube (2) is in direct communicating connection with the first tube (1) and an entire length of each of the first tube (1) and the second tube (2) are made of a material readily permeable for gases and substantially impermeable for body fluids and other substances, and an additional tubing (5) is connected to the second tube (2), wherein the outer diameter of the first tube (1) ranges from 2 to 4 mm and its wall thickness from 0.5 to 1.0 mm, and the outer diameter of the second tube (2) ranges from 1.0 to 1.5 mm and its wall thickness from 0.3 to 0.5 mm.

Abstract
The invention relates to a tonometric device (20) for examination of respiratory insufficiency and regional tissue perfusion failure in patients, comprising a distal end (22), a section (24) to be introduced into the body, and a fixing part (3). The section (24) to be introduced comprises a first tube (1) to which an additional tubing (4) is connected. A second tube (2) is arranged substantially parallel with the first tube (1). At least the section (24) of the first tube (1) is made of a material permeable for gases, especially for carbon'"'"' dioxide, but substantially impermeable for body fluids, preferably of silicone rubber. The device does not comprise any balloon, it can be introduced into the patient stomach without preliminary preparation, and is useful for examination of premature babies.
