Description

Dual-purpose gauze mask of doctor-patient

Technical Field

The invention belongs to the field of medical instruments, relates to the field of protective articles, and particularly relates to a medical and patient dual-purpose mask.

Background

The mask is an important protection tool for preventing and controlling respiratory infectious diseases. The existing common mask has two forms, one is without a breathing valve, the cost is low, the protection is comprehensive, but the condition that extra pressurization is needed in the bidirectional ventilation process exists, so that the breathing process of a wearer becomes laborious. The other mask is provided with an expiratory valve which is communicated in a one-way, so that the mask can smoothly exhaust, and the inspiratory process still needs extra force of a user. The above two kinds of masks are mainly used for protecting uninfected people (such as family members and doctors), but if the prevention and control can be performed from the perspective of the infection source, the infected people can be brought with the masks, so that the droplet infection can be isolated from the source, and the diseases can be more effectively prevented and controlled. And the infected person only needs to block the own droplets, the inhalation process does not need to be interfered, and the smoother inhalation process is more beneficial to the recovery of the patient. However, if doctors and patients use different masks, different production lines are set, which increases the production cost and is not beneficial to resource allocation in emergency.

Disclosure of Invention

The invention aims to introduce a one-way valve seat, so that the mask can be suitable for infected people and uninfected people according to requirements.

In order to achieve the purpose, the invention adopts the technical scheme that:

a medical and patient dual-purpose mask comprises a mask body, a flexible one-way valve seat and a one-way valve, wherein the flexible one-way valve seat is added into the medical and patient dual-purpose mask, and the one-way valve can be pushed to any surface of the mask, so that any surface of the mask can be worn outwards.

The structure of the mask body is basically consistent with that of a common mask with a breather valve removed, and the mask body comprises a mask surface, an elastic belt and a metal strip. The mask surface is of a multi-layer fabric structure and has air filtering capability, an opening for mounting the flexible one-way valve seat is reserved on the mask surface, and the mask surface does not contain other protrusions except the opening; the mask surface is divided into two completely identical surfaces, namely a surface A and a surface B, and the surface A is marked with: the infected person wears the face outward; indicated on panel B: the uninfected person wears the face outward. The two sides of the mask surface are provided with elastic bands for wearing the mask. The metal strips are embedded among the multiple layers of fabrics on the mask surface and are more attached to the mask when the mask is worn.

The flexible one-way valve seat is of a conical barrel-shaped structure made of flexible materials and comprises a large opening and a small opening, the large opening is connected with an opening on the mask surface, and the small opening is connected with the one-way valve. Because the one-way valve seat is made of flexible materials, the one-way valve seat can be manually pushed to any surface of the mask by a user, and then the one-way valve is driven to be positioned on any surface of the mask.

The one-way valve is positioned at the small opening of the one-way valve seat and is provided with the one-way valve, so that air can only pass from the surface A to the surface B.

The height of the one-way valve and the one-way valve seat can meet the following requirements: when the one-way valve seat is pushed to any side of the mask, the whole structure of the one-way valve is required to be on the side of the mask surface, and the condition that partial structure is still left on the other side cannot exist.

Further, the material of the one-way valve seat includes but is not limited to rubber, multi-layer non-woven fabric, woolen cloth and the like; structures which are convenient to be connected with other parts, including but not limited to a suture opening, a wing-shaped fixing piece and the like, can be reserved at the edges of the large opening and the small opening of the one-way valve seat; the cross-section of the cone-barrel structure is not necessarily circular.

Further, the specific implementation manner of the mask body includes, but is not limited to, that the strap is connected with the mask surface by sewing or gluing; the elastic belt and the mask surface are integrally molded.

The invention has the advantages that: can make the check valve can be pushed to the arbitrary one side of gauze mask through flexible one-way disk seat to make the one-way conductivity ability of gauze mask can be used to exhale or breathe in, reduction in production cost when satisfying different crowds demands.

Drawings

FIG. 1 is a view of the case when A is worn face-out;

fig. 2 shows the case when the B-side is worn out.

In the figure: the mask comprises a mask A face 1, a metal strip 2, a mask B face 3, a flexible one-way valve seat 4 and a one-way valve 5.

Detailed Description

The present invention is further illustrated by the following specific examples.

A dual-purpose mask for doctors and patients comprises a mask body, a flexible one-way valve seat 4 and a one-way valve 5.

The structure of the mask body is basically consistent with that of a common mask with a breather valve removed, and the mask body comprises a mask surface, an elastic belt and a metal strip 3. The mask face of the multilayer fabric structure comprises a mask A face 1 and a mask B face 3 which are the same, the mask face has air filtering capacity, an opening for installing a flexible one-way valve seat 4 is reserved on the mask face, elastic belts on two sides of the mask face and the mask face are integrally formed, and metal strips 3 are buried in an implanting interlayer of the mask face. The mask surface is characterized in that: 1) the mask surface does not contain other protrusions except the opening position; 2) the mask surface was divided into two identical faces, face a and face B, with red on face a indicating: the infected person wears the face outward, pushing the one-way valve to the face; red on side B indicates: the uninfected person wears the face outward, pushing the one-way valve to the face.

The flexible one-way valve seat 4 is of a rubber cone-barrel-shaped structure, and a large opening is bonded on an opening of the mask surface; the one-way valve 5 is located at the small opening of the flexible one-way valve seat 4 and has a one-way valve through which air can only pass from the a-side to the B-side. When an infected person wears the mask, the flexible one-way valve seat 4 is pushed to completely push the mask to the surface A (the one-way valve is on the surface A), and then the surface A of the mask is worn outwards; at the moment, the external air is directly led to the surface B from the surface A through the one-way valve 5, the air suction process of a patient is not interfered and is smoother, and the exhaled air is filtered through the mask surface to isolate droplet infection.

When the uninfected person wears the mask, the one-way valve seat is pushed to completely push the mask to the surface B of the mask (the one-way valve is on the surface B), and then the surface B of the mask is worn outwards; at the moment, the outside air is filtered through the mask surface to prevent infection, the exhaled air is directly led to the surface B from the surface A through the one-way valve 5, and the exhalation process is not interfered and is smoother.

The above-mentioned embodiments only express the embodiments of the present invention, but not should be understood as the limitation of the scope of the invention patent, it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the concept of the present invention, and these all fall into the protection scope of the present invention.
