Respiration assistance thoracic cavity saccule counterpulsation drainage device and respiration assistance drainage method

Abstract

The invention discloses a respiration assistance thoracic cavity saccule counterpulsation drainage device and a respiration assistance drainage method. The drainage device comprises a drainage tube, wherein the drainage tube is communicated with a liquid collector; an air bag is formed on the drainage tube, and is connected with one end of an air inlet tube; the other end of the air inlet tube is connected with a pressure controller; a drainage inlet is formed in the end, near the air bag, on the drainage tube; a pressure sensor is formed on the outer wall of the drainage tube arranged at the drainage inlet; and the pressure sensor is electrically connected with a pressure controller through a transmission wire. The drainage device and the drainage method have the advantages that the pressure in the thoracic cavity is detected through the pressure sensor arranged on the drainage tube; the pressure controller is controlled to generate positive pressure or negative pressure according to requirements; the pressure in the thoracic cavity is changed by the air bag for accelerating the discharging of gas and liquid from the thoracic cavity; the effect of a respiration pump is achieved; the effects of a simple respirator can be partially achieved but the relevant side effects of the respirator are avoided; the burden of the cardio-pulmonary function of a patient can be reduced; and the requirements of respiratory metabolism are met.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a breathing-assisted chest cavity balloon counterpulsation drainage device and a method thereof. Background technique [0002] The incidence of atelectasis and secondary pulmonary infection after thoracic surgery or severe chest trauma is relatively high, especially in the elderly, long-term smokers, acute and chronic respiratory infections, and severe chest trauma. The reasons are as follows: [0003] 1. Thoracic surgery requires tracheal intubation and ventilator-assisted breathing. The time for tracheal intubation is too long. The tracheal intubation balloon compresses the local tracheal mucosa, resulting in mucosal congestion, edema, exudation, and even necrosis. The cilia lose their function, resulting in accumulation of secretions. Efficient discharge. [0004] 2. The postoperative incision pain makes the patient dare not take a deep breath and cough hard, which leads to th...

AI Technical Summary

Problems solved by technology

[0003] 1. Thoracic surgery requires tracheal intubation and ventilator-assisted breathing. The time for tracheal intubation is too long. The tracheal intubation balloon compresses the local tracheal mucosa, resulting in mucosal congestion, edema, exudation, and even necrosis. The cilia lose their function, resulting in accumulation of secretions. effective discharge

[0004] 2. The postoperative incision pain makes the patient dare not take a deep breath and cough hard, which leads to the ineffective discharge of sputum, mucus, and blood clots in the bronchi

[0005] 3. For those who smoke for a long time before operation and have a history of chronic lung disease, their ventilatory reserve function decreases, FEV1.0 decreases, the smooth muscle hyperplasia of the bronchiole wall, the cartilage ring collapses, the lumen is narrowed, the ventilation and ciliary motor function are affected, and the self-purification function decreases

[0006] 4. Did not pay attention to respiratory function exercise before operation, and did not master the correct cough method after operation

[0007] 5. Pneumonia and effusion in the pleural cavity caused by poor closed chest drainage tube and wall adhesion

[0008] 6. After surgery (especially sleeve lobectomy, lobectomy, segmentectomy, etc.), the angle of the bronchus changes and the cilia are damaged, which affects the discharge of sputum.

Greatly increase the suffering of patients, prolong the length of hospital stay, increase medical expenses, and consume social resources
