Description

Technical Field

[0001] This invention relates to the field of thoracic surgery nursing technology, specifically to a vibration-assisted sputum expectoration device for thoracic surgery nursing. Background Technology

[0002] Thoracic surgery nursing is a professional care focused on patients with chest diseases, covering preoperative preparation and postoperative recovery guidance. Thoracic surgery nursing involves collaboration with a multidisciplinary team of doctors, respiratory therapists, and others to jointly develop a patient care plan.

[0003] In thoracic surgery clinical nursing practice, vibration sputum clearance technology has become an important means to help patients clear respiratory secretions. Currently, the mainstream vibration sputum clearance devices mainly cover two types: pneumatic vest type and handheld vibration head type. Among them, the pneumatic vest type device drives the chest wall to vibrate to achieve sputum clearance by alternating inflation and deflation of the built-in airbag. However, because its core components are integrated inside the vest, it is very easy to cause airway sealing failure due to micro-damage during cleaning and disinfection. Moreover, the fixed size design makes it difficult to adapt to the individualized needs of patients with different body types. In contrast, although the vibration head type device can vibrate the lung area on the back, it is highly dependent on the nurse's hand operation, which increases the human workload and brings many inconveniences to clinical nursing work.

[0028] Working principle: During installation, the female hook and loop fastener 205 is attached to the surface of the male hook and loop fastener 102, so that the first zipper assembly 103 and the second zipper assembly 206 are connected, thereby fixing the bottom sealing connecting fabric 204 to the back of the fixed isolation vest 101. During disassembly, the first zipper assembly 103 and the second zipper assembly 206 are pulled apart, and the male hook and loop fastener 102 and the female hook and loop fastener 205 are torn apart, so that the bottom sealing connecting fabric 204 is separated from the fixed isolation vest 101, thereby allowing the fixed isolation vest 101 to be washed separately. When adjusting the height of the vibrating airbag 402, the electromagnetic brake 212 is activated, and the drive motor 211 is started. The drive motor 211 drives the transmission wheel 209 to rotate through the first wheel shaft 207. The transmission wheel 209 drives the transmission rope 210 on the surface to move. The moving transmission rope 210 drives the sliding seat 301 to slide along the inside of the guide rail groove 215 through the rope receiving tube 312, thereby realizing the height adjustment of the vibrating airbag 402. After the vibrating airbag 402 is adjusted to the specified height, the electromagnetic brake 212 is activated to lock the second wheel shaft 208, thereby locking the transmission wheel 209 on the surface of the second wheel shaft 208, thereby positioning the transmission rope 210 and the sliding seat 301, and thus realizing the height positioning of the support shell 401 and the vibrating airbag 402. When adjusting the pressure of the support shell 401 and the vibrating airbag 402 on the back, the electromagnetic coil 305 is energized. After the electromagnetic coil 305 is energized, it generates a magnetic field with the opposite polarity to that of the magnet 306, so that the polarities of the electromagnetic coil 305 and the magnet 306 are the same at their proximal ends, thereby generating a repulsive force. This repulsive force, combined with the elastic force of the pre-tension spring 304, forms a pushing force on the lifting seat 302, causing the lifting seat 302 to rise. When the lifting seat 302 rises, it presses down the adapter frame 407 through the transmission link 408. The pressed adapter frame 407 presses the support shell 401 and the vibrating airbag 402 tightly against the back of the fixed isolation vest 101, thereby making the vibrating airbag 402 close to the patient's back. By changing the magnetic force of the electromagnetic coil 305, the pressure of the vibrating airbag 402 on the patient's back can be changed. During vibration, connect the external connector 406 to the output pipe of the high-frequency chest wall oscillation sputum suction device, start the high-frequency chest wall oscillation sputum suction device, and the high-frequency chest wall oscillation sputum suction device generates periodically changing airflow that enters the air distribution chamber 405. Through the connection of the air guide hose 404 to the vibration airbag 402, the periodically changing airflow drives the vibration airbag 402 to periodically expand and contract. During vibration-assisted sputum clearance, first, attach the female Velcro 205 to the back of the fixed isolation vest 101. Then, connect the external connector 406 to the output pipe of the high-frequency chest wall vibration sputum clearance device. Next, pull the tightening rope 105 to bring the fixed isolation vest 101 into contact with the patient's body. Then, tie and secure the tightening rope 105. Next, adjust the height of the vibration airbag 402 to cover the lung area on the back. Then, adjust the pressure of the support shell 401 and the vibration airbag 402 on the back. Then, start the high-frequency chest wall vibration sputum clearance device to make the vibration airbag 402 vibrate periodically. The periodic vibration of the vibration airbag 402 taps the patient's back, thereby achieving vibration-assisted sputum clearance for the patient.
