Problems solved by technology

While such a sensor has several advantages: 2-3 minutes is sufficient as far as the examination is concerned, it is easy to perform, and is similar to taking body temperature in the mouth, keeping the sensor in place throughout the examination is a challenge. Difficult and requires patient cooperation
Additional disadvantage is the need to frequently calibrate the sensor between measurements
Thus, the sensor is disposable and the display part is expensive

Embodiment Construction

[0025] In a preferred embodiment, the device of the invention is a probe 20 having a section 24 formed for guiding it into the patient's gastrointestinal tract, and this section comprises two parallel Tubes 1 and 2. The material of tubes 1 and 2 should be readily permeable to gases, but substantially impermeable to any other substance, especially to other substances of body fluids. This material can be any flexible substance like a plastic material, especially a polymer, such as polyethylene, polyvinyl chloride, polyurethane, polyvinyl acrylate or polycarbonate, but also latex, silicone or silicone rubber.

[0026] The diameters of the tubes 1 and 2 of the probe 20 may be the same or different. The probe 20 in FIG. 1 includes a thicker tube 1 and a thinner tube 2 . At the distal end of the probe 20 at the end of the section 24 to be introduced into the gastrointestinal tract of the patient, the tube 2 is connected to the end of the tube 1 , for example with a gas-tight join...

Abstract

The invention relates to a pressure measuring device (20) for examining respiratory insufficiency and local tissue perfusion disorders in a patient, the pressure measuring device (20) comprising a distal end (22), a section (24) to be introduced into the body and fixed part (3). The section (24) to be introduced consists of the first pipe (1) to which an additional pipe (4) is connected. The second tube (2) is arranged substantially parallel to the first tube (1). At least a section (24) of the first tube (1) is manufactured from a material permeable to gases, especially carbon dioxide, but substantially impermeable to bodily fluids, preferably silicone rubber. The device does not include any balloons, can be introduced into a patient's stomach without prior preparation, and can be used to examine premature infants.

Description

technical field [0001] The present invention relates to diagnostic probes and kits for manometric examination of respiratory insufficiency and regional perfusion disorders of the body. Background technique [0002] Manometry devices have been widely used in medical practice to examine the partial pressure of specific tissues in relation to the concentration of carbon dioxide, referred to as pCO, throughout the gastrointestinal tract, especially in the stomach 2 , for measurements made within the stomach and / or gastrointestinal system, the partial pressure of carbon dioxide is specifically referred to as p g CO 2 . Under steady-state circulation, this partial pressure of carbon dioxide is nearly equal to that of arterial blood; thus, the method has proven useful for detecting disorders of the respiratory regulatory system. Conversely, in acutely ill patients, tissue-specific pCO 2 Values ​​higher than pCO in blood 2 value. The difference between these two values ​​is re...
