Breathing assembly supporting voice function, ventilation method thereof and breathing machine

Abstract

The invention discloses a breathing assembly supporting a voice function, a ventilation method thereof and a breathing machine, and the breathing assembly comprises: a monitoring module which is usedfor monitoring the mouth end pressure and the expiratory pressure of a patient; an air suction module which is used for providing air for the patient during air suction; an expiration module which isused for exhausting gas generated by expiration of the patient and further used for controlling the pressure of the expiration branch to be larger than the pressure of the mouth end according to the pressure, monitored by the monitoring module, of the mouth end, wherein meanwhile the pressure of the expiration channel is increased due to lung contraction in the expiration process of the patient, so that gas in the expiration channel of the patient does not pass through the expiration branch, but flow to the mouth, and the vocal cord of the patient vibrates and makes a sound. Compared with a voice valve in the prior art, the breathing assembly does not need to be dismantled, element abrasion can be avoided, and therefore cost is reduced, and meanwhile due to the fact that dismantling is notneeded, clinical operation is easy, and the sound production requirement of a patient can be rapidly met.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a breathing assembly supporting voice function, a ventilating method and a ventilator. Background technique [0002] Tracheotomy refers to cutting the trachea of ​​the patient's neck and inserting a tube to solve problems such as dyspnea and respiratory dysfunction. Patients who undergo tracheotomy clinically need intubation for assisted breathing and gas exchange with the outside world. The gas does not flow through the upper airway and vocal cords, making it impossible to make a sound, which hinders communication between doctors and patients. Now clinically, the voice valve is used to help the patient to make a sound. The principle is to use a one-way valve to prevent the exhaled gas from passing through the exhalation branch of the tracheal intubation, so as to pass through the upper airway and make the vocal cords vibrate and make a sound. [0003] However, when...

AI Technical Summary

Problems solved by technology

[0003] However, when using the voice valve, the intubation tube needs to be removed to install the voice valve, and the voice valve needs to be removed after use

Some patients can quickly adapt to the voice valve, while some patients need to gradually increase the time of wearing the voice valve through training. Repeated disassembly of the voice valve will cause complicated clinical operations and wear of components, resulting in increased costs

There are also some voice valves that are designed to be embedded in the intubation tube, but they still need to be reinstalled, the operation steps are not simplified, and at the same time, they need to conform to the design of respiratory mechanics, which increases the production cost of the product

Therefore, there is the problem of inconvenient use in the existing voice valve device
