Abstract
Description
Technical Field
[0001] This application relates to the technical field of medical devices, and in particular, to a medical breathing mask. Background Art
[0002] A breathing mask is a device that transfers oxygen from a storage tank into the human lungs. The breathing mask can cover the nose and mouth (oral-nasal mask) or the entire face (full-face mask). Oxygen masks are mainly made of plastic, silicone, or rubber. When in use, the bottom of the mask contacts the human face and is fixed with an elastic band. The mask connector is docked with external ventilators, anesthesia machines, etc. to achieve oxygen supply and anesthesia operations for patients.
[0003] The current masks usually have an inflatable airbag at the bottom, etc., and the airbag contacts the patient's face to ensure good airtightness. However, patients who usually use breathing masks need to wear them for a long time. At the same time, due to the need to ensure airtightness, there is a certain downward pressure, which will to a certain extent hinder blood flow and may seriously cause local skin necrosis, which is not conducive to the recovery of patients. Manually adjusting the position of the mask intermittently will also increase the burden of nursing work. Therefore, to solve the above problems, this application provides a medical breathing mask.
[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content
[0005] In order to solve the problem that the existing mask is prone to cause muscle necrosis by continuously squeezing one place, this application provides a medical breathing mask.
[0006] A medical breathing mask provided by this application includes a mask body and a connector that constitute the breathing mask, and a fastener for cooperating with an elastic band is arranged on the outside of the connector. The bottom end of the mask body is separately provided with an outer airbag and an inner airbag, which are arranged at equal intervals between the outer airbag and the inner airbag, and the outer airbag and the inner airbag alternately expand. An air charging and discharging structure for controlling the expansion of the outer airbag and the inner airbag is arranged outside the mask body.
[0007] Preferably, a rigid spacer fixedly connected to the mask body is arranged between the outer airbag and the inner airbag.
[0008] Preferably, the height of the spacer is less than the diameter of the outer airbag or the inner airbag after expansion.
[0009] Preferably, the air charging and discharging structure includes an outer air tube communicated with the outer airbag, and a valve is arranged on the outer air tube.
[0010] Preferably, the air charging and discharging structure further includes an inner air tube communicated with the inner airbag, and a valve is also arranged on the inner air tube.
[0011] Preferably, an operation ball is detachably installed at the end of the outer trachea or the inner trachea.
[0012] In summary, the present application includes the following beneficial technical effects:
[0013] By arranging two equidistant outer airbags and inner airbags below the cover body, and the outer airbag and the inner airbag are independent of each other, they can be inflated separately to contact the patient's face, so that the convenient switching of the fitting position can be realized. Compared with the manual position switching of the prior art, the convenience of operation is improved, and at the same time, the airtight effect is not lost.
[0014] The device is provided with two independent tracheas, and valves are arranged on the tracheas, so that the inflation operation of the two airbags can be conveniently realized, and thus the convenient switching of the airbags can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following further describes the present application in detail with reference to the Figure 1 - Figure 5 drawings.
[0022] Embodiment 1: Refer to Figure 1 - Figure 4, a medical breathing mask, comprising a mask body 1 and a connector 2 that form the breathing mask, and a fastener 3 for cooperating with an elastic band is arranged on the outer side of the connector 2. It is characterized in that: an outer airbag 4 and an inner airbag 6 are separately arranged at the bottom end of the mask body 1, the outer airbag 4 and the inner airbag 6 are arranged at equal intervals, the outer airbag 4 and the inner airbag 6 expand alternately, an air charging and discharging structure for controlling the expansion of the outer airbag 4 and the inner airbag 6 is arranged outside the mask body 1, a rigid spacer 9 fixedly connected to the mask body 1 is arranged between the outer airbag 4 and the inner airbag 6, the height of the spacer 9 is less than the diameter after the expansion of the outer airbag 4 or the inner airbag 6, the spacer 9 ensures the mutual independence between the outer airbag 4 and the inner airbag 6, and at the same time, there is a certain distance between the spacer 9 and the lowest end position of the airbag, avoiding discomfort for the patient due to its rigid material.
[0023] The air charging and discharging structure includes an outer air tube 5 communicated with the outer airbag 4, and a valve 8 is arranged on the outer air tube 5. The air charging and discharging structure further includes an inner air tube 7 communicated with the inner airbag 6, and a valve 8 is also arranged on the inner air tube 7. The valve 8 is used to control the on-off of the inner air tube 7 or the outer air tube 5. During the use of the mask, the outer airbag 4 can be inflated at intervals. Connect the outer air tube 5 to an external inflation device, open the valve 8, inflate, after the inflation is completed, close the valve 8, then open the valve 8 on the inner air tube 7, and release the gas in the inner airbag 6. At this time, the inner airbag 6 no longer has pressure on the skin below it, while the outer airbag 4 presses on the skin, so as to ensure the restoration of blood circulation in the skin below the inner airbag 6. In this way, the inner airbag 6 can also be inflated, while the outer airbag 4 deflates, realizing the exchange of the pressing position and avoiding local necrosis caused by too long pressing.
[0024] Embodiment 2: Refer to Figure 5 , a medical breathing mask, comprising a mask body 1 and a connector 2 that form the breathing mask, and a fastener 3 for cooperating with an elastic band is arranged on the outer side of the connector 2. It is characterized in that: an outer airbag 4 and an inner airbag 6 are separately arranged at the bottom end of the mask body 1, the outer airbag 4 and the inner airbag 6 are arranged at equal intervals, the outer airbag 4 and the inner airbag 6 expand alternately, and an air charging and discharging structure for controlling the expansion of the outer airbag 4 and the inner airbag 6 is arranged outside the mask body 1.
[0025] The air charging and discharging structure includes an outer air tube 5 communicated with the outer airbag 4, and a valve 8 is arranged on the outer air tube 5. The air charging and discharging structure further includes an inner air tube 7 communicated with the inner airbag 6, and a valve 8 is also arranged on the inner air tube 7. An operation ball 10 is detachably installed at the end of the outer air tube 5 or the inner air tube 7. One-way valves with the same direction of air flow are arranged at both ends of the operation ball 10. When the operation ball 10 is pressed, the air inside it enters the air tube. After releasing the operation ball 10, under the action of its own elasticity, the external air flow enters its interior from the other end, and in this way, the convenient inflation operation is completed reciprocally.
[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
