Description

Technical Field

[0001] The present invention relates to an expiratory positive pressure oscillation device, and more particularly, to an expiratory positive pressure oscillation device that is easy to disassemble, assemble, and clean. The expiratory positive pressure oscillation device comprises a base and a detachable cover. The detachable cover comprises a front cover and a rear cover. The user can easily assemble the front cover, allowing the first magnetic component of the front cover to quickly achieve the correct working position. Furthermore, the user can easily disassemble the front cover, allowing the first magnetic component of the front cover to quickly move out of the working position, making the expiratory positive pressure oscillation device easier to clean. Background Art

[0002] Expiratory Positive Oscillation Pressure (OPEP) Therapy is a treatment method for airway clearing. When the user actively exhales into the OPEP device, the OPEP device will provide resistance and create positive intrathoracic pressure to increase lung volume and expand the upper airway. In particular, the OPEP device's expiratory positive pressure oscillation can enhance the intensity of ciliary beating, making the airway clearing more effective.

[0003] The prior art, such as the US patent No. US6581598, mainly discloses a positive expiratory pressure device. When the user applies positive expiratory pressure at the patient input end (202), air pressure is applied to the cone (425) of the rocker assembly (400) through the opening (326) to close the opening (326); wherein the expiratory pressure will cause the cone (425) to rise, so that the joystick assembly (400) overcomes the magnetic field force between the magnet (350) carried on the pivot magnet support (330) and the steel pin (450) carried on the joystick assembly, and rotates around the magnet (350) and the steel pin (450) carried on the joystick assembly. The pivot pin (460) pivots; as the cone (425) moves upward, the conical configuration of the conical interior (325) of the connector (322) increases the effective exhaust area, thereby reducing the patient-induced expiratory pressure exerted on the cone (425); when the magnetic force of the air and the Venturi effect overcome the air pressure applied to the cone (425), the cone (425) will move downward again into the conical surface (325), momentarily closing the expiratory air flow through the opening (326).

[0004] The patent family for this prior art includes German Patent No. DE60035328T2, European Patent No. EP1103287B1, and Spanish Patent No. ES2288832T3. The conventional rotatable adjusting dial 600 has a complex structure, comprising at least an abutment 611, a pair of guides 650, two cam surfaces 641, 642, a circumferential groove 660, a circumferential flange 661, a guide tab 665, and a flange 661. This makes it difficult to disassemble and clean, and difficult to reassemble after cleaning. Therefore, there is still a need for improvement in this prior art. Summary of the Invention

[0005] In response to the improvement needs of the above-mentioned prior art, the present invention aims to provide an expiratory positive pressure oscillation device that is easy to disassemble, assemble and clean, the expiratory positive pressure oscillation device comprising a base, a rocker arm pivotally mounted on the base, a detachable cover, a first magnetic component and a second magnetic component; an air inlet passage of the base is provided with a manifold, the rocker arm has a convex valve body, the manifold fixes a valve seat, the detachable cover is composed of a front cover and a rear cover, the first magnetic component is arranged on the rocker arm, the second magnetic component is arranged on a sliding seat of the front cover, and the sliding seat is located above the first magnetic component; wherein the base and the front cover are positioned by a positioning column, and the front cover and the rear cover are positioned by a hook, so that the first magnetic component can quickly reach the correct working position through the front cover and quickly leave the working position through the front cover.

[0006] Advantageous Effect (1) of the present invention is that the detachable cover is composed of a front cover and a rear cover, making it easy for the user to assemble the front cover, allowing the first magnetic component of the front cover to quickly reach the correct working position. Furthermore, the user can easily disassemble the front cover, allowing the first magnetic component of the front cover to quickly move out of the working position, making it easy to clean the positive pressure oscillation device.

[0007] The second beneficial effect of the present invention is that the rear cover has an extension on both sides, each extension having a plurality of exhaust slots, and the exhaust slots are adjacent to the valve seat to shorten the exhaust path; the moment the exhaled air flow drives the convex valve body to separate from the conical tube, the exhaled air flow is discharged through the exhaust slots, thereby reducing exhaust backflow and avoiding interference with the rocker arm and oscillation frequency.

[0008] The third advantage of the present application is that the rocker arm is pivoted to the pair of pivot seats of the base by a pivot, one end of which is fixed with a first stopper; after the pivot passes through the pivot holes of the pivot seats and a pivot hole of the rocker arm, the other end of the pivot is sleeved with a second stopper, so that the rocker arm is quickly assembled by the pivot and the second stopper and is quickly disassembled by the second stopper.

[0024] Please refer to Figures 1 to 6. In a preferred embodiment, the exhalation positive pressure oscillation device of the present invention includes a base 10, a rocker arm 20, a valve seat 30, a detachable cover 40, a first magnetic component 50, and a second magnetic component 60. The base 10 has an air inlet channel 11, a manifold 12 is provided on the side of the air inlet channel 11, and the rear end of the air inlet channel 11 is fluidically connected to an air inlet portion 13; the rocker arm 20 has a convex valve body 21, and the rocker arm 20 is pivotally mounted on the base 10; the valve seat 30 has a tapered tube 31 to accommodate the convex valve body 21, and the valve seat 30 is fixed to the manifold 12; the detachable cover The body 40 is composed of a front cover 41 and a rear cover 42. The removable cover 40 is fixed to the base 10 to accommodate the rocker arm 20 and the valve seat 30. The first magnetic assembly 50 is disposed on the front end 25 of the rocker arm 20, and the second magnetic assembly 60 is disposed on a sliding seat 70 of the front cover 41, with the sliding seat 70 positioned above the first magnetic assembly 50. The base 10 and the front cover 41 are positioned by a positioning post 15, and the front cover 41 and the rear cover 42 are positioned by a hook 43, allowing the first magnetic assembly 50 to quickly reach the correct working position through the front cover 41 and quickly disengage from the working position through the front cover 41. Therefore, the user can easily assemble and disassemble the front cover 41, and the expiratory positive pressure oscillation device is easy to clean.

[0025] Please refer to Figures 6 to 8 for an explanation of the exhalation positive pressure oscillation process of a preferred embodiment: When the user exhales, the exhaled airflow generates a positive thrust in the conical tube 31, driving the rocker arm 20 to rotate. The distance between the first magnetic component 50 and the second magnetic component 60 is shortened, generating a reverse thrust (as shown in Figure 7). The moment the convex valve body 21 separates from the conical tube 31, the positive thrust decreases (the pressure of the airflow is instantly released), and according to the Bernoulli equation, the airflow continues to pass through the conical tube 31. When the convex valve body 21 closes the conical tube 31, the convex valve body 21 and the conical tube 31 feedback an exhalation resistance (as shown in FIG8 ); the rocker arm 20 generates an exhalation positive pressure oscillation through the cyclic action of the forward thrust and the reverse thrust (as shown in FIG7 and FIG8 ).

[0026] The following describes how the front cover 41 and the base 10 are assembled: a positioning post 15 is formed on the base 10 and located at a circular end 14 thereof. The front cover 41 has a positioning portion 45, which positions the base 10 and the front cover 41 relative to each other (as shown in Figure 6). Furthermore, the positioning post 15 can be a polygonal hollow post, and the positioning portion 45 can be a polygonal frame to prevent relative rotation between the front cover 41 and the base 10. Furthermore, the front cover 41 has a curved bottom edge 44, which secures the front cover 41 against the circular end 14 of the base 10. Therefore, the front cover 41 is easily assembled with the base 10 and easily removed from the base 10 for cleaning. After cleaning, the front cover 41 and the base 10 can be easily reassembled using the positioning post 15 and the positioning portion 45 (as shown in Figures 3 and 6).

[0027] The front cover 41 and the rear cover 42 are assembled as follows: the front cover 41 has a multi-curved edge 48, and the rear cover 42 has a multi-curved stepped surface 49. The front cover 41 is secured to the multi-curved stepped surface 49 via the multi-curved edge 48. Furthermore, a hook 43 is formed on the front cover 41 and located on the multi-curved edge 48 (as shown in FIG. 3 ). The multi-curved stepped surface 49 of the rear cover 42 has a hook slot 430 (as shown in FIG. 2 ). The hook 43 and the hook slot 430 secure the front and rear covers 41 and 42 to each other (as shown in FIG. 6 ). Therefore, the front and rear covers 41 and 42 are easy to assemble and disassemble for cleaning. After cleaning, the front and rear covers 41 and 42 can be easily reassembled using the hook 43 and the hook slot 430 (as shown in FIG. 2 and FIG. 6 ).

[0028] The rear cover 42 and the base 10 are assembled as follows: The rear cover 42 has an upper track 42a (e.g., a track formed by a long, rectangular protrusion) on either side, and the base 10 has a lower track 10a (e.g., a track formed by a long, rectangular groove) on either side. When the upper track 42a penetrates the lower track 10a, the rear cover 42 is secured to the base 10 (as shown in Figures 2 and 4). Furthermore, the rear cover 42 has an extension 46 on either side, each of which has a plurality of exhaust slots 460. The exhaust slots 460 are located adjacent to the valve seat 30 to shorten the exhaust path (as shown in Figure 6). The moment the exhaled airflow drives the convex valve body 21 away from the tapered tube 31, the exhaled airflow is discharged through the exhaust slots 460, reducing exhaust backflow and preventing interference with the rocker arm 20 and the oscillation frequency (as shown in Figures 7 and 8).

[0029] The materials and functions of the rear cover 42 are listed and described: the material of the rear cover 42 can be selected from transparent material, translucent material, or opaque material to give the expiratory positive pressure oscillation device different identification functions and textures. For example, if the material of the rear cover 42 is transparent, after disassembly and cleaning, the user can identify whether the expiratory positive pressure oscillation device has been correctly reassembled and whether the oscillation function is normal.

[0030] The following describes how the rocker arm 20 and the base 10 are combined: the base 10 has a pair of pivot seats 16 (as shown in FIG2 ), and the rocker arm 20 is pivoted on the pivot seats 16 via a pivot 17; a first stop block 18 is fixed to one end 171 of the pivot 17, and after the pivot 17 passes through the pivot holes 161 of each pivot seat 16 and a pivot hole 26 of the rocker arm 20, a second stop block 19 is sleeved on the other end 172 of the pivot 17 (as shown in FIG2 to FIG4 ), so that the rocker arm 20 can be quickly assembled and disassembled via the pivot 17 and the second stop block 19.

[0031] The combination of the sliding base 70 and the front cover 41 is illustrated as follows: the sliding base 70 has a plurality of sliding hooks 71, and the sliding base 70 hooks a sliding slot 410 of the front cover 41 through the plurality of sliding hooks 71, so that the sliding base 70 slides on the front cover 41 through the sliding slot 410 (as shown in Figures 3 and 6); each sliding hook 71 has a protrusion 72, and the sliding slot 410 has a plurality of recesses 411. The sliding base 70 forms a plurality of positioning points (as shown in Figure 5) through each protrusion 72 and the plurality of recesses 411 to fine-tune the working position of the second magnetic component 60 (as shown in Figure 6).

[0032] Please refer to Figures 1 to 12 for an illustration of the inhalation method of the exhalation positive pressure oscillation device: A one-way valve 80 is further disposed on a circular end 14 of the base 10. This one-way valve 80 comprises a one-way valve seat 81 and a one-way valve disc 82. The one-way valve seat 81 has a plurality of air inlet holes 83 (as shown in Figure 2). When the user inhales, the inhaled air flows through the plurality of air inlet holes 83, pushing the one-way valve disc 82 to open the one-way valve 80 and enter the air inlet passage 11 (as shown in Figure 9). When the user exhales, an exhaled airflow passes through the air inlet passage 11 to close the one-way valve 80, and the exhaled airflow generates a forward thrust in the conical tube 31 to drive the rocker arm 20 to rotate. The distance between the first magnetic component 50 and the second magnetic component 60 is shortened, generating a reverse thrust (as shown in FIG10 ). The moment the convex valve body 21 separates from the conical tube 31, the forward thrust decreases, and the reverse thrust drives the rocker arm 20 to return to its original position. The moment the convex valve body 21 closes the conical tube 31, the convex valve body 21 and the conical tube 31 feedback an exhalation resistance (as shown in FIG11 ). The rocker arm 20 generates an exhalation positive pressure oscillation through the cyclic action of the forward thrust and the reverse thrust (as shown in FIG10 and FIG11 ).

[0033] Please refer to Figures 13 and 14, which list and illustrate how to add a mouthpiece to the exhalation positive pressure oscillation device: the air inlet portion 13 of the base 10 is further fluidically connected to a mouthpiece 90 (for example: a connecting tube 92 of the mouthpiece 90 is fixed to the air inlet portion 13), and the mouthpiece 90 has a curved portion 91 to form a better angle of use.
