Description

Technical Field

[0001] The invention relates to the technical field of medical supplies, and in particular to a breathing mask. Background Art

[0002] When using a ventilator to help patients breathe, a breathing mask is required. The structure of the breathing mask includes a hard cover, a trachea interface set on the cover for connecting the ventilation pipeline, a wearing belt connected to the cover, and a decompression cushion connected to the cover. Patients who cannot breathe independently need to use a ventilator for a long time, and the breathing mask is worn for a long time. Although the decompression cushion on the breathing mask has a certain anti-pressure injury function, because the decompression cushion is pressed on the same part of the face for a long time, the compressed part cannot be relaxed, and it is easy to get pressure injuries after being compressed for a long time. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide an anti-pressure breathing mask device to solve the technical problem that the existing respirator mask will fixedly apply pressure to the same part of the face when in use, which is easy to cause facial pressure injuries.

[0004] The anti-pressure breathing mask device of the present invention comprises a hard mask shell, a trachea interface and a wearing belt are connected to the mask shell, a circle of supporting sheet is arranged at the edge of the mask shell, and an inner decompression air cushion ring and an outer decompression air cushion ring for contacting with facial skin are arranged on the supporting sheet;

[0005] The anti-pressure breathing mask device also includes a first bronchus connected to the inner decompression gasket and a second bronchus connected to the outer decompression gasket, the first bronchus is provided with a first electromagnetic reversing valve, and the second bronchus is provided with a second electromagnetic reversing valve;

[0006] The anti-pressure breathing mask device also includes an air pump, an exhaust pipe connected to the air outlet of the air pump, and a three-way joint connected to the outlet of the exhaust pipe, the first bronchus is connected to one outlet of the three-way joint, and the second bronchus is connected to the second outlet of the three-way joint;

[0007] The anti-pressure breathing mask device also includes a controller for controlling the switching of the first electromagnetic reversing valve and the second electromagnetic valve.

[0008] Furthermore, the first electromagnetic reversing valve and the second electromagnetic valve are two-position three-way electromagnetic valves.

[0009] Furthermore, the inner pressure-reducing air gasket and the outer pressure-reducing air gasket are silicone gaskets.

[0010] Beneficial effects of the present invention:

[0011] The anti-pressure injury breathing mask device of the present invention arranges an inner pressure-reducing air cushion ring and an outer pressure-reducing air cushion ring on the edge of the mask shell, and controls the inner pressure-reducing air cushion ring and the outer pressure-reducing air cushion ring to be alternately inflated and deflated; when the inner pressure-reducing air cushion ring is inflated and pressed on the facial skin, the outer pressure-reducing air cushion ring is deflated and released from the facial skin; when the outer pressure-reducing air cushion ring is inflated and pressed on the facial skin, the inner pressure-reducing air cushion ring is deflated and released from the facial skin; in this way, the breathing mask no longer applies fixed pressure to the same part of the face, and the problem of pressure injury to the face caused by wearing the breathing mask for a long time can be effectively avoided.

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] As shown in the figure, the anti-pressure breathing mask device in this embodiment includes a hard mask shell 1, to which a trachea interface 2 and a wearing strap 3 are connected, and a circle of support sheet 4 is provided on the edge of the mask shell, and an inner decompression air cushion ring 5 and an outer decompression air cushion ring 6 for contacting the facial skin are provided on the support sheet.

[0016] The anti-pressure breathing mask device also includes a first bronchus 7 connected to the inner decompression gasket and a second bronchus 8 connected to the outer decompression gasket. The first bronchus is provided with a first electromagnetic reversing valve 9, and the second bronchus is provided with a second electromagnetic reversing valve 10.

[0017] The anti-pressure breathing mask device also includes an air pump 11, an exhaust pipe 12 connected to the air outlet of the air pump and a three-way joint 13 connected to the outlet of the exhaust pipe, the first bronchus is connected to one outlet of the three-way joint, and the second bronchus is connected to the second outlet of the three-way joint.

[0018] The anti-pressure breathing mask device further comprises a controller 14 for controlling the switching of the first electromagnetic reversing valve and the second electromagnetic valve.

[0019] In this embodiment, the first electromagnetic reversing valve and the second electromagnetic valve are two-position three-way electromagnetic valves.

[0020] The anti-pressure injury working principle of the anti-pressure injury breathing mask device in this embodiment is as follows:

[0021] After the breathing mask is worn on the patient's face, the controller 14 controls the first electromagnetic reversing valve and the second electromagnetic valve to be reversing at a set interval. When the first electromagnetic reversing valve is controlled to connect the first bronchus 7 with the exhaust pipe 12, the inner decompression gasket 5 is inflated and pressed on the facial skin; after the inner decompression gasket is inflated, the second electromagnetic valve is immediately controlled to be reversed to disconnect the second bronchus 8 from the exhaust pipe 12. After disconnection, the second bronchus 8 is connected to the atmosphere, and the outer decompression gasket 6 is deflated and loosened from the facial skin. When the set interval is reached, the controller first controls the second electromagnetic reversing valve to be reversed to connect the second bronchus 8 with the exhaust pipe 12, so that the outer decompression gasket 6 is inflated and pressed on the facial skin; then the first electromagnetic valve is immediately controlled to be reversed to disconnect the first bronchus 7 from the exhaust pipe 12. After disconnection, the first bronchus 7 is connected to the atmosphere, and the inner decompression gasket 5 is deflated and loosened from the facial skin.

[0022] In this way, the inner decompression gasket 5 and the outer decompression gasket 6 are alternately inflated and deflated, so that the breathing mask no longer applies fixed pressure to the same part of the face, which can effectively avoid the problem of facial pressure injuries caused by wearing the breathing mask for a long time.

[0023] As an improvement to the above-mentioned embodiment, the inner decompression air cushion ring and the outer decompression air cushion ring are silicone air cushion rings; the silicone air cushion has good contact comfort with the skin and can improve the anti-pressure injury effect.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
