Description

Electric sputum aspirator

Technical Field

Background

Sputum aspiration is a common operation in clinical care and home care, and particularly for patients incapable of spontaneously expelling sputum, such as intensive care patients, postoperative patients and respiratory tract infection patients, timely and effective sputum aspiration is an important means for maintaining respiratory tract patency and preventing infection and complications. At present, the traditional manual sputum aspirator is gradually replaced by an electric sputum aspirator due to complex operation and low efficiency.

The existing electric sputum aspirator generally relies on a negative pressure air pump to generate negative pressure, and sputum in the respiratory tract of a patient is sucked out through a drainage tube. However, these devices have some problems in practical use: the existing electric sputum aspirator generally adopts a constant negative pressure mode, and the structure of the device is simplified, but the electric sputum aspirator has a great risk in actual operation. When the front end of the drainage tube is blocked or adsorbed on the inner wall of the respiratory tract of a patient, the constant negative pressure easily causes damage to the respiratory tract. In sputum aspiration operation, medical staff needs to accurately judge the position of the front end of the drainage tube, and can effectively aspirate sputum without injuring the airway. However, the existing device lacks an effective observation means, and medical staff can only judge the position of the drainage tube through the hand feeling change during operation or the sound of the negative pressure air pump, so that the operation difficulty is increased, and higher requirements are also put on the experience and skill of the medical staff. The operation interface and the control mode of the existing electric sputum aspirator are complex, and medical staff can be used skillfully after professional training. In emergency or home care environments, ease and intuitiveness of operation is particularly important. The complex operation not only increases the workload of the healthcare staff, but may also delay the optimal treatment timing. The sputum aspiration procedure involves the patient's body fluids and cleaning and disinfection of the device is particularly important. However, the structural design of the existing devices is inconvenient to detach and clean, and is prone to risk of cross infection, and particularly, the sanitation problem is more remarkable when a plurality of patients share one set of devices.

In view of the foregoing, there is a need for an improved device that addresses these issues.
