Description

Technical Field

[0001] The invention relates to the technical field of medical care, in particular to a sputum removal auxiliary device. Background Art

[0002] For patients with lung infection, timely clearing of lung secretions is one of the most important steps in the treatment process, because sputum is composed of protein and contains a large number of pathogens. If sputum is retained in the airway for a long time, it will aggravate the respiratory infection and even excessive sputum will accumulate in the airway and block the airway. Patients will experience a series of symptoms of hypoxia: breath holding, difficulty breathing, and even suffocation. Patients with lung infection have very weak respiratory function, so expectoration is even more important. Generally, the nursing staff in the department will first manually tap the patient's back before expectorating the patient. The vibration will cause the sputum in the trachea to fall off, which will help the subsequent expectoration work.

[0003] In order to assist patients in expectorating, some hospitals use expectoration assist devices to imitate the back-banging vibration to assist patients in expectorating. However, most general expectoration assist devices use a vibrating vest or a vibrating head to vibrate the patient's body. The use of the vibrating head requires manual assistance from medical staff throughout the process. The vibrating vest fits tightly against the patient's body during use, and after inflation, it will compress the patient's chest cavity, making it inconvenient for the patient to cough and expectorate. In addition, if the vibrating vest malfunctions during use or the patient is unwell, it cannot be quickly separated immediately. Summary of the invention

The hook 512 is rotatably connected to one end of the waist binding belt 509. By providing the ventilation frame 501, the roller frame 502, the support roller 503, the buffer roller sleeve 504, the insertion strip 505, the first elastic band 506, the hanging ring 507, the second elastic band 508, the waist binding belt 509, the waist belt sleeve 510, the lumbar support pad 511 and the hook 512, the waist of the patient can be fixed by the waist binding belt 509 during back slapping, which improves the stability and avoids compressing the patient's chest cavity at the same time, ensuring that the patient can stop back slapping at any time to achieve a non-compressive fixation and rapid separation mechanism.

[0034] Working principle: During storage, the device is folded and installed on the wall at the head of the hospital bed; When providing lighting, as Figure 3 shown, manually unfold the backrest plate 101 so that the lighting lamp 104 faces downward to provide lighting; during back slapping, as Figure 2As shown, clean the sundries at the head end of the hospital bed surface. After manually unfolding the backrest plate 101 to an appropriate angle, start the adjustment motor 212. The adjustment motor 212 drives the driving bevel gear 213 through the worm and worm gear reducer 211. The driving bevel gear 213 drives the driven bevel gear 214 to rotate. The driven bevel gear 214 drives the electric support rotating shaft 210, causing the extension arms 205 at both ends of the electric support rotating shaft 210 to rotate. The extension arms 205 drive the backrest plate 101 to adjust to an appropriate angle and ensure that the support roller 503 supports the hospital bed surface. Then, energize the heating rod 308 and adjust the temperature of the thermostat 309. The heating rod 308 heats the heat-conducting liquid to a specified temperature and conducts heat through the hot compress liquid bag 301. Then, the patient leans back on the hot compress liquid bag 301. After adjusting the position, pass the waist belt 509 around the waist and hang the hook 512 on the hanging ring 507. At this time, the device forms a hot compress on the patient. Then, energize the ring-shaped electromagnet 415. After the ring-shaped electromagnet 415 is energized, its current direction changes periodically, causing the permanent magnet 417 to be attracted and pushed out periodically. When the permanent magnet 417 is attracted and pushed out periodically, it will periodically draw and push the transmission liquid through the driving piston 416, causing the driven piston 408 to be drawn periodically by hydraulic transmission. The back pat conduction head 407 drives the sponge back pat pad 409 to form a periodic vibrating back pat on the patient's back. The vibrating back pat frequency is from ten to fifty hertz to correspond to different sputum viscosity levels, so as to assist the patient in expectorating phlegm. When in use, the back pat frequency can be changed by changing the current commutation frequency of the ring-shaped electromagnet 415, and the start and stop of the sponge back pat pad 409 can be changed by changing the on / off of the solenoid valves 404 at different positions. When the back pat is uncomfortable, the patient can lean forward to separate the back from the hot compress liquid bag 301 and then lean back to continue the back pat after waiting for relief.
