Technical Field

[0001] The invention relates to a medical cough-assisting expectorant device, in particular to a vibration-assisted expectorant device. Background Art

[0002] Vibration expectoration is a common operation after respiratory diseases and lung surgery. In elderly patients, due to incorrect expectoration methods or weak coughing, sputum accumulates in the respiratory tract, which aggravates the disease and may even lead to respiratory failure, seriously affecting the treatment and prognosis of patients. At present, the main method of expectoration is the use of expectorant drugs, such as Mucosolvan injection, Cherno tablets, nebulization, etc., and vibration expectoration is a simple and effective important method. At present, nursing staff or teaching patients' family members to use hollow palms to hit the patient's back to achieve the effect of expectoration, but because the rhythm, strength and method of each person's back patting are different, the expectoration effect is greatly weakened, and the palm is prone to fatigue when patting repeatedly, resulting in unsustainable expectoration, which seriously affects the efficiency of expectoration. The vibrating expectorators currently used in clinical practice are usually large and bulky, and require professional use, which is extremely inconvenient, so they are now basically limited to use in ICU (intensive care unit). Therefore, a simpler, more convenient, practical and efficient vibrating expectorator is needed clinically. Summary of the invention

[0004] To this end, the present invention provides a vibration-assisted expectoration device, including a handle, a shell and an end. A motor assembly, a vibration assembly and a speed regulating device are arranged in the shell. A replaceable power supply is arranged in the handle, and the power supply is electrically connected to the speed regulating device. The speed regulating device is electrically connected to the motor assembly. The speed regulating device adjusts the speed frequency of the motor assembly. The motor assembly controls the vibration assembly to vibrate up and down. The speed regulating device has a speed regulating knob. The handle can be rotatably sleeved on the upper end of the shell and connected to the speed regulating knob in the shell. Rotating the handle drives the speed regulating knob to rotate, thereby adjusting the speed frequency of the motor assembly. The end is arranged at the lower end of the shell and connected to the vibration assembly.

[0005] In the present invention, the principle of artificial back patting to expel sputum is imitated, and the principle of up and down vibration of the vibrator is utilized. The sputum is loosened by up and down reciprocating vibration to facilitate coughing out. The motor speed is adjusted by rotating the handle, thereby adjusting the vibration frequency. It is suitable for the needs of various patients and is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
