Problems solved by technology

[0003] 1. When the mask is worn, breathing is difficult due to the limited space in the cavity of the mask. Wearing it for a long time will cause lung discomfort or even lung damage. Therefore, general masks need to be removed when worn for 2 to 4 hours. It is not allowed to wear masks for strenuous exercise; for medical staff who work on the front line of anti-epidemic for a long time, it is impossible to take off the masks halfway, the discomfort and even physical damage felt are particularly obvious, and some medical staff even fainted due to wearing masks for a long time ;
[0004] 2. Due to the rapid outbreak of the epidemic, the supply of masks is in short supply, especially for medical masks, which have many production processes and low production efficiency, making it difficult to meet the needs of epidemic prevention

Embodiment 1

[0028] Such as Figure 1~4 As shown, a kind of anti-suffocation mouth mask device, comprises airtight mouth mask body 1 and auxiliary respirator 4, described mouth mask body 1 both sides are provided with transom 3, described transom 3 and mouth mask body 1 are integrally formed, in A replaceable filter disc 6 is provided in the louver 3, and the front end of the mouth mask body 1 is provided with a vent, and a replaceable filter disc 6 is also provided at the vent, and the outer end of the vent is connected to the auxiliary respirator 4 Removable connection, the mask body 1 is fixed to the wearer's ear or head through the binding part 2, and the auxiliary respirator 4 includes a folding telescopic tube 4-1, embedded in the wall of the folding telescopic tube 4-1 Inside the return spring 4-2, the outer end of the folded telescopic tube is provided with a first one-way valve 4-3 only for gas to flow into the tube, and the inner end is connected to the vent port, and is provided...

Embodiment 2

[0037] On the basis of embodiment 1, this embodiment has made further improvement, and its difference with embodiment 1 is:

[0038] The mask body 1 is made of airtight fabric.

[0039] Working principle of the present invention is:

[0040] 1. By replacing the filter sheet 6, the present invention can be used for a long time, which greatly reduces the cost of mask consumption. Specifically, the filter sheet 6 can be mass-produced on automated machinery through molds. Due to the simple process, the production capacity can be greatly improved , reduce mask consumption;

[0041]2. When the auxiliary respirator 4 is not needed for normal wearing, the auxiliary respirator 4 can be unscrewed and breathed through the air port and the louver 3;

[0042] 3. When the auxiliary respirator 4 needs to be used, for example, in a long-time social occasion, or a medical staff working for a long time, the auxiliary respirator 4 can be screwed on, and the foldable telescopic tube 4-1 can be ...

Abstract

The invention discloses an anti-suffocation mask device, which relates to the technical field of medical equipment, and comprises an air-tight mask body and an auxiliary respirator, air windows are arranged on two sides of the mask body, replaceable filter discs are arranged in the air windows, an air vent is arranged at the front end of the mask body, the replaceable filter discs are arranged atthe air vent, and the outer end of the air vent is detachably connected with the auxiliary respirator. The mask device can effectively relieve the suffocation feeling when a user wears the mask, enables the user to breathe smoothly, protects the lung health, and is suitable for long-time social occasions and long-time anti-epidemic working occasions of medical staff. And meanwhile, the replaceablefilter disc is arranged, so that the procedures of a mask production line can be greatly reduced, the production efficiency is improved, and the large-scale anti-epidemic supply requirement is met.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anti-breathing mask device. Background technique [0002] In addition to home isolation, masks as traditional epidemic prevention devices have become very scarce. At present, masks with preventive effects recognized by the public include medical disposable masks, medical surgical masks, medical N95 masks, medical KN95 masks, etc. The materials of these masks Most of them are composed of waterproof layer, filter layer and skin-friendly layer. Although they can play a certain role in epidemic prevention, they still have the following defects: [0003] 1. When the mask is worn, breathing is difficult due to the limited space in the cavity of the mask. Wearing it for a long time will cause lung discomfort or even lung damage. Therefore, general masks need to be removed when worn for 2 to 4 hours. It is not allowed to wear masks for strenuous exercise; for medical staff ...
