Description

The expiratory positive pressure oscillation device is easy to disassemble, assemble and clean

The invention relates to an exhalation positive pressure oscillation device, in particular to an exhalation positive pressure oscillation device that is easy to disassemble, assemble and clean. The exhalation positive pressure oscillation device has a base and a detachable cover. The detachable cover Consisting of a front cover and a rear cover, the user can easily assemble the front cover, so that the first magnetic element of the front cover can quickly reach the correct working position. Furthermore, the user can easily disassemble the front cover, so that the first magnetic element of the front cover can quickly leave the working position, and it is easy to clean the expiratory positive pressure oscillation device.

OPEP Therapy is a treatment method for airway cleaning. When the user actively exhales on the OPEP device, the OPEP device will provide resistance to form a positive intrathoracic pressure to increase lung volume and expand the upper airway. In particular, the positive expiratory pressure oscillation of the OPEP device can enhance the strength of ciliary beating, so that the effect of airway cleaning is better.

Known technology such as U.S. Patent No. US6581598 mainly discloses a positive pressure exhalation device (Positive expiratory pressure device). Air Pressure is applied to the cone (425) of the rocker assembly (400) to form the closure of the opening (326); where the expiratory pressure will raise the cone (425) so that the rocker assembly (400) overcomes its pivotal position. The magnetic field force between the magnet (350) carried on the shaft magnet support (330) and the steel pin (450) carried on the rocker assembly pivots about its pivot pin (460); when the cone (425 ) moves upward, the conical configuration of the conical interior (325) of the coupler (322) increases the effective expulsion area, thereby reducing the patient-induced exhalation pressure exerted on the cone (425); when As the magnetic force of the air and the Venturi effect overcome the air pressure applied to the cone (425), the cone (425) will again move down into the conical surface (325), momentarily shutting off the exhalation flow through the opening (326).
