Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical instrument and equipment, and particularly relates to a sputum excretion device with a multidirectional damping structure. BACKGROUND

[0002] In the prior art, many diseases of the human body can cause increased secretion of sputum, including diseases such as pneumonia, bronchiectasis, bronchial asthma, and pulmonary fibrosis, and timely promotion of the migration and removal of airway secretions is indispensable for chest physical extracorporeal mechanical treatment, and a high-frequency oscillation sputum excretion device is the preferred choice in the medical field.

[0003] The high-frequency oscillation sputum excretion system used in the sputum excretion device mainly delivers air into the high-frequency oscillator cavity through the air blower, excites the pressure sensor to deliver a signal to the control panel, and controls the high-frequency oscillator to work, relying on the high-frequency oscillator to periodically inhale and exhale air, excite the pulsation of the airflow, and input the gas in the high-frequency oscillator cavity to the vest through the air guide pipe, and the pulsating airflow produces mechanical vibration on the vest, which is similar to the action of a human palm patting the back of a patient, thereby assisting the patient in excreting sputum.

[0004] In the working process of the high-frequency oscillation sputum excretion device, the lower the vibration and noise, the more superior the mechanical dynamic performance, the longer the service life, and the better the quality. However, the existing high-frequency oscillation sputum excretion device has the following shortcomings:

[0005] (1) The device has large vibration, large noise, and short service life: this is mainly because the existing high-frequency oscillation sputum excretion device adopts a suspended front and rear clamping high-frequency oscillator, specifically suspending and clamping the high-frequency oscillator in the middle of the front and rear buffer support blocks, and fastening the front and rear buffer support members to the plastic rear shell through screws, which cannot concentrate the mass of the high-frequency oscillator in the rigid part of the device, and the elastic modulus of the plastic rear shell is low. Since the high-frequency oscillator is a dynamic balance that constantly changes in high-frequency vibration, the cross-sectional size of the suspension is small, and the mass of the entire vibration assembly is distributed on the contact surface of the elastic front and rear buffer support blocks, the damping support and constraint conditions are not enough, the damping effect is not good, the buffer support blocks are directly subjected to the dynamic balance of the high-frequency oscillator that constantly changes in high-frequency vibration, which easily causes the device to shake, and even causes the desktop on which the sputum excretion device is placed to vibrate. Due to the large vibration, the structural noise is also relatively obvious, and the service life of the plastic rear shell is also relatively short due to the long-term influence of vibration.

[0006] (2) The air outlet is directly connected to the exhaust hole of the high-frequency oscillator without anechoic structure, and the vibration of the air guide pipe connected to the vest and the air outlet is large due to the influence of the airflow excitation force.

[0007] (3) the front shell where the display screen and touch screen of the device are located is directly fastened on the rear shell or frame by screws, and the air outlet directly abuts against the front shell, due to the large mechanical vibration caused by the exciting force in the air guide pipe connected with the air outlet, the front shell is vibrated, and the human-computer interaction use experience of the display screen and touch screen is not good.
