Description

Manual control jet ventilation device of tracheal intubation guide tube with ventilation function

Technical Field

The utility model belongs to the field of medical instruments, and particularly relates to a manual control jet ventilation device of a tracheal intubation guide tube with a ventilation function.

Background

Jet ventilation is a common ventilation mode in air passage management, and air flow is sprayed into an air passage of a patient through a jet ventilation pipe under low pressure by a jet ventilation device to ensure oxygenation. The method can be divided into high-frequency jet ventilation and low-frequency jet ventilation according to the frequency, the low-frequency jet ventilation can be manually controlled, and the low-frequency jet ventilation can be implemented only by manually controlling a jet ventilation device and an oxygen source. The hand controlled jet aerator is one hand controlled handle type jet aerator comprising mainly oxygen supplying pipeline, pressure gauge, handle, oxygen supplying pipe and thyrocricocentesis kit and is easy to carry about. The manual control jet ventilation oxygen supply device can be connected with the cricothyroid membrane puncture connector through the extension tube through the manual control valve to carry out manual control jet ventilation, and oxygen is sent into the airway of a patient through the extension tube. The manual control jet ventilation technology has the characteristics of low tidal volume, low intrathoracic pressure and end-expiratory pressure, can reduce the damage of lung tissues and air passages, can obviously shorten the rescue time when rescuing patients, increases gas exchange, and quickly improves the anoxic state of the patients.

In intensive care units, many patients require long-term retention of the endotracheal tube for ventilator ventilation, but endotracheal tube replacement is required in the following cases: 1. damaging the air bag of the tracheal catheter; 2. twisting or flattening the tracheal tube; 3. the model of the tracheal catheter needs to be changed; 4. the sputum scab attached to the inner wall of the trachea is not easy to be sucked out. The current common guide tube for replacing the tracheal cannula is a plastic solid hose with the length of about 50cm and the diameter of 5mm, and has certain support property. When the tracheal catheter needs to be replaced, the guide tube is lubricated and then inserted into the tracheal cannula, the position and the insertion depth of the tracheal cannula are fixed, the air bag is loosened, the tracheal cannula is pulled out, a new tracheal cannula is inserted into the guide tube until the original depth is reached, the guide tube can be pulled out, and whether the position of the new tracheal cannula is proper or not is checked so as to be stably fixed.

The problems existing at present are as follows:

1. the manual control jet ventilation device can effectively improve the oxygenation of a patient, but the existing equipment only provides a cricothyroid membrane puncture connection oxygen supply pipeline, does not have a connector directly connected with a tracheal cannula, and cannot be connected with a tracheal catheter for oxygen supply in an airway.

2. Intensive care unit patients often have complicated pulmonary diseases and long-term mechanical ventilation, long intubation time with trachea, poor oxygenation function, and are difficult to tolerate an anoxic state. At present, a tracheal intubation guide tube is generally adopted for replacing the tracheal intubation, but the guide tube is a solid hose, so that oxygen can not be provided in the process of replacing the tracheal intubation, and the tracheal intubation is replaced for a long time under the anaerobic supply condition for patients without spontaneous respiration and poor oxygen storage or patients with difficult tube replacement, so that the patients are extremely easy to suffer from oxygen deficiency, even a series of adverse consequences such as respiratory sudden cardiac arrest occur, and the like, and potential safety hazards exist.
