Description

A facial isolation sampling protective mask

Technical Field

The invention relates to the technical field of medical appliances, and in particular to a facial isolation sampling protective cover.

Background Art

Every pneumonia patient needs a nucleic acid test to be diagnosed, and the specimens tested are generally throat swabs. However, when nurses ask patients to open their mouths and take throat swab specimens from their throats, it is very easy to get infected. At present, when taking throat swab specimens, patients usually need to take off their masks to cooperate with medical staff. Because there will be a certain amount of throat irritation during this process, patients are likely to cough, sneeze, vomit, etc., which means that a large number of droplets carrying pathogens may be spread.

Summary of the invention

In view of the shortcomings of the prior art, the present invention provides a facial isolation sampling protective cover, which overcomes the shortcomings of the prior art and has a reasonable design. The blocking piece allows the sampling port to only pass through the end of the throat swab sampling tool, while other parts are in a blocked state, thereby effectively preventing the spraying of droplets and aerosols in the patient's mouth, greatly improving the safety factor during sampling.

To achieve the above objectives, the present invention is implemented through the following technical solutions:

A facial isolation sampling protective mask comprises a mask assembly, a liner and a sampling port assembly;

DETAILED DESCRIPTION

In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

Please refer to Figures 1-8, the present invention provides a technical solution: a facial isolation sampling protective mask, including a mask assembly, a liner 1 and a sampling port assembly;

Among them, the mask assembly includes a mask body 2, a telescopic ring 3, an elastic binding belt 4 and an expansion ring 6, the elastic binding belt 4 is connected to the mask body 2, the mask body 2 is provided with an installation opening 5, the outer ring surface of the telescopic ring 3 is tightly connected to the edge of the installation opening 5, the inner ring surface tension of the telescopic ring 3 is greater than the outer ring surface tension of the telescopic ring 3, when worn, the inner ring surface has a concave state biased toward the face direction and a convex state biased away from the face direction; the expansion ring 6 is tightly connected to the inner ring surface of the telescopic ring 3, and the outer diameter of the expansion ring 6 is greater than the inner diameter of the telescopic ring 3; the telescopic ring 3 needs to be pre-treated during production and processing to make the inner ring surface tension greater than the outer ring surface tension, so as to achieve stable convexity or stable concavity along the axial direction; the tension of the inner ring surface of the telescopic ring will be insufficient over time, resulting in unreliable convex or concave state, and the expansion ring 6 is added to further limit the tension effect of the inner ring surface of the telescopic ring 3;

The liner 1 comprises a tube body 7 and an internal clamp ring 8; an external thread a9 is provided at one end of the tube body 7, the internal clamp ring 8 is sleeved on the tube body 7, and a support leg extends from the tube body 7 and away from the end of the external thread a9; the support leg comprises a symmetrically arranged left support leg 17 and a right support leg 18, and the left support leg 17 and the right support leg 18 are symmetrically supported on both sides of the mouth and nose, and a second protective pad 19 is provided at the end of the support leg; the present invention innovatively adopts the liner 1, and when in use, the adopted liner 1 is retracted and supported on the face to ensure the stability of the support, and the second protective pad 19 provided on the support leg can reduce the damage to the face. In the present invention, the cover body is clamped between the liner 1 and the external clamp ring 12 on the sampling port assembly, which can effectively fix the cover body and improve the stability during use; in addition, the second protective pad 19 includes a rubber layer, a foam layer and a release layer compounded in sequence, and the second protective pad 19 is bonded to the support foot. The second protective pad 19 is adhesively connected to the support foot to facilitate later replacement. In addition, the protective pad has good cushioning protection performance, which further improves the wearing comfort.

The sampling port assembly includes a mounting cover 10 and a baffle 11. An external clamp ring 12 is fixedly mounted on one side of the mounting cover 10. An internal thread a13 is provided on the inner wall of the mounting cover 10. With the matching connection of the external thread a9 and the internal thread a13, the expansion ring 6 is clamped between the internal clamp ring 8 and the external clamp ring 12. A sampling port is provided in the middle of the mounting cover 10, and the baffle 11 is evenly installed in the sampling port. Therefore, when sampling nucleic acid for a patient, the patient can first be asked to wear the protective cover of the present invention, and the patient's oral cavity is aligned with the sampling port. The nurse can then pass through the sampling port through the throat swab sampling tool to smoothly enter the patient's oral cavity to take the throat swab specimen. Because when passing through the sampling port, the baffle 11 is used to make the sampling port only pass through the end of the swab, and the other parts are all in a blocking state, thereby effectively preventing the spraying of droplets and aerosols in the patient's oral cavity, greatly improving the safety factor during sampling. Furthermore, since the sampling port assembly is connected by the internal thread a13 and the internal thread a13, it is convenient to disassemble, assemble and replace the sampling port assembly after sampling, so as to facilitate cleaning and disinfection.

In this embodiment, the position of the sampling port may also correspond to the patient's nostril, so that when sampling, the nasal swab sampling tool may pass through the sampling port into the patient's nasal cavity to take the specimen.

In the present invention, the baffles 11 can be uniformly arranged strip-shaped plastic baffles, one end of which is fixedly mounted on the inner surface of the sampling port, and the other end of which is in contact with the inner surface of the sampling port. Therefore, when the throat swab sampling tool is inserted, one or two of the strip-shaped plastic baffles will bend inward, while the other strip-shaped plastic baffles remain in a blocking state, so as to effectively prevent the spraying of droplets and aerosols in the patient's mouth.

In the present invention, the baffle 11 can also be a circular baffle with a cross opening in the middle. When inserting the throat swab sampling tool, it can enter the patient's oral cavity from the cross opening, and the elastic effect of the cross opening makes other parts all blocked.

In the present invention, the mask assembly further includes a first protective pad 16, which is an annular structure, and has a card slot 14, which is engaged with the edge of the mask body 2, and a plurality of rubber protrusions 15 are evenly distributed on the surface of the first protective pad 16. The rubber protrusions can increase the friction of the face; in the present invention, the first protective pad 16 can be detachably connected to the edge of the mask body 2, which can increase the comfort of wearing.

The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
