Description

Trachea cannula catheter air bag air pressure monitoring device

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a trachea cannula pipe gasbag air pressure monitoring device.

Background

The establishment of the artificial high-grade airway of the critical patient is an effective means for ensuring the airway to be unobstructed, and plays an extremely important role in the rescue process.

However, the establishment of artificial high-grade airways also damages and destroys to some extent the normal physiological anatomical functions of the body. In a sedated state or a critically ill patient with disturbance of consciousness, the artificial high airway enables the epiglottis of the patient to be in a semi-open state, the glottis is exposed outside, the swallowing function is inhibited, and the patient cannot discharge the oropharyngeal secretions out of the body, so that the oropharyngeal secretions or gastrointestinal tract refluxes are retained above the subglottal gasbag, and the oropharyngeal and gastrointestinal tract refluxes mostly contain a large amount of bacteria, fungi, acidic substances and the like.

In order to solve the problems, the tracheal intubation catheter is provided with an air bag structure, so that the functions of closing an airway and fixing the catheter are achieved, the supply of tidal volume is guaranteed, and oropharyngeal secretions are prevented from entering the lung, so that the occurrence of complications such as lung infection, tracheal injury and the like is reduced. Ensuring the proper pressure of the air bag is an important prerequisite for ensuring the function of the air bag and reducing related injuries.

The monitoring value of the air bag pressure is composed of the elastic retraction force of the air bag, the extrusion force of the air pipe wall to the air bag and the impact force generated by the air passage pressure. The normal value range pressure (25-30 cmH 2O), if the air bag is not inflated enough, namely the air bag pressure is less than 20cmH2O, oropharyngeal secretions and stomach contents enter the lung along air bag folds and the tracheal wall, inhalation pneumonia, airway mucosal injury, ulceration and the like are caused, meanwhile, the occurrence probability of ventilator-associated pneumonia can be increased, the course of disease of a patient is prolonged, even the life is critical and the like; if the air inflation amount of the air sac is too large, the capillary perfusion of the tracheal mucosa is obviously reduced when the air sac pressure exceeds 30cmH2O (22 mmHg), and the blood supply of the tracheal mucosa is completely blocked when the air sac pressure reaches 50cmH2O (37 mmHg), so that the airway injury, necrosis, perforation and the like are finally caused.

Therefore, the key point for improving the success rate of the treatment of the critical patients is to manage the air bag pressure, and the ideal air bag pressure is to keep the minimum pressure for effectively sealing the gap between the air bag and the trachea and prevent the air bag from oppressively damaging the mucous membrane.

Chinese patent No. CN201620488587 discloses a tracheal catheter balloon pressure monitoring alarm, wherein it also discloses a housing, a processor, a pressure monitor, an air leakage monitor, an audible and visual alarm and a display screen are arranged in the housing, the left lower side of the housing is connected with an air bag inflation connector, and the right side of the housing is connected with an injector. When the device is used, the current pressure value is monitored by the pressure monitor and displayed on the display screen, the current air leakage is monitored by the air leakage monitor, and the inflation volume and the inflation time interval are obtained after processing.

The tracheal catheter air bag pressure monitoring alarm has the following defects:

first, the structure is tedious, requiring the entire pressure monitoring alarm to be moved to the patient's bedside and connected to the endotracheal tube, taking up excessive space.

Secondly, the inflation efficiency is low, and the injector is not directly connected with the indicating air bag, but is integrated on the shell, which is equivalent to prolonging the inflation channel.

Third, since the housing must be located near the patient, the medical personnel cannot move far away or hear the alarm.
