Lung lavage device

Abstract

The invention provides a lung lavage system. The lung lavage system comprises a positive-pressure and negative-pressure power element capable of generating positive pressure and negative pressure, a lung lavage pipeline (102) and a gas, liquid and solid mixing module (104), wherein the lung lavage pipeline comprises an aerial fog inlet air path and an aerial fog exhausting air path; the aerial fog inlet air path is an air path from an exhausting hole of the positive-pressure and negative-pressure power element to a patient; the aerial fog exhausting air path is an air path from the patient to an air inlet of the positive-pressure and negative-pressure power element; the gas, liquid and solid mixing module is arranged at the downstream of the positive-pressure and negative-pressure power element in the aerial fog inlet air path. The lung lavage system provided by the invention is a brand new lung lavage method capable of discharging foreign matters in lungs; the positive-pressure and negative-pressure power element capable of generating the positive pressure and the negative pressure is used as a power source of the aerial fog inlet air path and the aerial fog exhausting air path, so that the system is simplified; the positive pressure and the negative pressure alternately switches to convey aerial fog to the lungs of the patient and exhaust the aerial fog; the foreign matters in the lungs are discharged by utilizing inertia and the time is very short in each time of lung lavage, so that influences on breathing are small and the patient feels more comfortable.

Description

technical field [0001] The invention relates to the medical field, in particular to a lung washing system. Background technique [0002] Pneumoconiosis is a systemic disease mainly caused by diffuse fibrosis (scarring) of lung tissue caused by long-term inhalation of productive dust (dust) during occupational activities and retention in the lungs. One of the current treatments for patients with pneumoconiosis involves large-volume whole-lung lavage. This operation is to bathe the patient's lungs under general anesthesia. The usual practice is that the doctor inserts a "Y"-shaped double-lumen bronchial tube through the patient's mouth to separate the left and right lungs. The "Y"-shaped double-lumen bronchial catheter inserted into the lungs is mainly used to separate "air and water": one lung is supplied with oxygen and ventilated by an anesthesia ventilator to maintain the body's gas exchange; the other lung is connected to lavage The tubing is lavaged (lung washed).

AI Technical Summary

Problems solved by technology

[0003] 1. Doctors have high technical requirements, and the intubation position error generally cannot exceed 1 cm

[0004] 2. There are potential safety hazards. After all, it is a highly professional operation. During the lung washing process, certain water pressure injuries, barotrauma, and even irreversible damage may occur.

If you do not pay attention to some subtle links, such as the water temperature of the lavage fluid or the postoperative care measures are not in place, or the two lungs are the same, causing the patient to suffocate, it is very likely that the patient will die

[0005] 3. Many patients are not suitable for this operation, such as those with cardiovascular disease, blood disease, or organic diseases such as liver, kidney, and brain; or malformations of the trachea and main bronchus, etc.

[0008] 1. It usually takes too long to send the aerosol into the patient's lungs and inhale the aerosol, the patient's breathing will be substantially affected, and there is even a risk of gas suffocation

[0009] 2. Use a vacuum pump to suck the mist. If the time is too short, you may not be able to pump out much mist, which will affect the cleaning effect.

[0010] 3. When the patient washes the lungs with aerosol, in consideration of safety and affecting the patient's breathing, the patient cannot participate, and a second person, such as a doctor or nurse, is required to perform it, which is very inconvenient and even limits the application occasions, such as only in hospital

[0011] 4. The aerosol entering the patient's lungs may separate into liquid water, which is the same as the aforementioned whole lung lavage, creating a dangerous situation of water-soaked lungs again.
