Embodiment

[0018] Such as figure 1 As shown, the respiratory resistance and power detection catheter of the present invention includes a catheter body 11, and also includes an upper airway micro-pressure sensing chip 15, an esophageal micro-pressure sensing chip 16, a gastric micro-pressure sensing chip 17, and esophageal electrodes 1-2. 10. Such as figure 2 As shown, the catheter body 11 is provided with a wire lumen 12 for accommodating a wire 13 and an air lumen 14 for communicating with the atmosphere.

[0019] Wherein, the upper airway micro-pressure sensing chip 15 is a differential pressure micro-pressure sensing chip, which is provided with two pressure contact surfaces for measuring the upper airway pressure (taking atmospheric pressure as a reference), and is installed on the top of the catheter body 11; When the respiratory resistance and power detection catheter is placed in the human body for measurement, the upper airway micro-pressure sensor chip 15 is located in the up...

Abstract

The invention discloses a respiratory resistance and power detection catheter, which comprises a catheter body, an upper airway micro pressure sensing chip, an esophagus micro pressure sensing chip, a stomach micro pressing sensing chip and an esophagus electrode, wherein a lead tube cavity for accommodating a lead is formed in the catheter body; the upper airway micro pressure sensing chip is used for detecting the upper airway pressure; the esophagus micro pressure sensing chip is used for detecting the esophagus pressure; the stomach micro pressing sensing chip is used for detecting the stomach pressure; and the esophagus electrode is used for detecting a diaphragm electric signal. The respiratory resistance and power detection catheter has the function of detecting the upper airway resistance and the respiratory center driving simultaneously, so that pain caused by repeated insertion of the catheter into the body of a patient is avoided.

Description

technical field [0001] The invention relates to a medical detection catheter, in particular to a respiratory resistance and power detection catheter. Background technique [0002] In patients with sleep apnea, the upper airway dilator muscles relax during sleep, resulting in narrowing of the upper airway and causing ventilation disorders. Patients with chronic obstructive pulmonary disease often experience decreased ventilation and respiratory failure at night; it is not clear whether the reason is due to increased upper airway resistance at night, decreased central respiratory drive, or both. Because of the different treatment methods for respiratory failure caused by increased upper airway resistance and decreased central respiratory drive, it is very important to distinguish between the two. However, there is no catheter that can simultaneously detect the drive of the respiratory center and the resistance of the upper airway. [0003] Diaphragm is the main respiratory m...
