Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
As shown in fig. 1 to 3, a medical mask with oxygen inhalation and high efficiency filtration functions comprises a mask body 1, wherein a filter screen for filtering droplets and aerosol is arranged on the mask body 1. The two sides of the mask are provided with a bandage 2 for fixing. The mask body 1 is provided with an elbow 3 which is communicated with a gas storage bag 4, and the end part of the elbow 3 extending into the inner side of the mask body 1 is provided with a one-way valve 5. And an air inlet pipe 6 for connecting the oxygen therapy apparatus is provided on the bent pipe 3. Oxygen provided by the oxygen therapy device is introduced into the air storage bag 4 through the air inlet pipe 6 and the bent pipe 3 or enters the inner side of the inlet cover body 1 through the one-way valve 5. When the oxygen flow that the oxygen therapy apparatus provided can not satisfy patient's demand of breathing in, the oxygen in the gas storage bag 4 then gets into the inlet cover body 1 through check valve 5 in, is favorable to providing sufficient oxygen suppliment flow for the patient.
As shown in fig. 4, a hollow rubber ring 7 is installed at the opening of the mask; the rubber ring 7 is filled with a gas or liquid-like fluid. Be equipped with the mount of supporting usefulness on the lateral wall of rubber ring 7 outer ring, the mount is used for finalizing the design to the lateral wall profile of rubber ring 7 to scribble on the lateral wall of rubber ring 7 full viscose and fixed with gauze mask body 1, the opening of gauze mask can not warp, guarantees fixed firm. The top of the inner ring of the rubber ring 7 is provided with an angular recess 8, and the angular recess 8 is used for clamping the nose bridge, so that the rubber ring 7 is conveniently attached to the protruding part of the nose bridge.
Wherein, the rubber ring 7 is provided with an adjusting hole, and an adjusting pipe 9 is arranged on the adjusting hole to communicate with an adjuster with adjustable volume. The regulator comprises a hollow cylindrical cylinder body 10 communicated with the rubber ring 7, and a movable rubber plug 11 is arranged in the cylinder body 10. By adjusting the filling volume of the fluid by changing the amount of the rubber stopper 11, the expansion and contraction of the rubber ring 7 can be controlled. Moreover, because the outer ring profile of the rubber ring 7 is supported by the fixing frame, the volume variable of the rubber ring 7 is concentrated at the inner ring, so that the fit degree of the rubber ring 7 and the face is higher; the tightness of the rubber ring 7 is ensured.
As shown in fig. 5, in order to adjust the amount of the rubber stopper 11 inserted, a cap 12 is sleeved on the cylinder 10; an external thread is provided on the outer side wall of the cylinder 10, and an internal thread adapted to the external thread is provided on the cylindrical lid body 12. The cap 12 is screwed to the cylinder 10 from the open end of the cylinder 10. The bottom of the cover body 12 is integrally formed with a connecting rod 13 fixed with the rubber plug 11. The cover body 12 is rotated to move the cover body 12 toward the cylinder body 10, and the connecting rod 13 on the cover body 12 drives the rubber plug 11 to go deep into the cylinder body 10, so as to reduce the volume of the cylinder body 10. Because cylinder body 10 and annular rubber ring 7 intercommunication, the fluid in the cylinder body 10 can be extruded in annular rubber ring 7, and rubber ring 7 takes place the inflation, makes the profile of rubber ring 7 inner ring and human face hug closely, prevents that gas from leaking from gauze mask body 1 and facial clearance, and the leakproofness is good.
In order to ensure that the mask body 1 and the elbow 3 are firmly fixed, a fixing piece 14 is also stuck on the mask body 1; the fixing piece 14 is composed of two hard plates, and the mask body 1 is clamped by the two hard plates from the inner side and the outer side. The two hard plates are fixed in a hot riveting mode. One end of the bent tube 3 passes through the fixing piece 14 and extends into the mask body 1. Can avoid influencing the installation of return bend 3 because of the material of gauze mask body 1 is softer.
In order to ensure the filtering effect, the filter screen sequentially comprises three filter layers from outside to inside; the first filter layer is an antistatic spunbond microfiber layer having a coating of electrically charged electrospun sub-micrometer fibers; the coating may be comprised of microfibers, sub-micrometer fibers, nanofibers interwoven with partially gelled sub-micrometer fibers, or combinations thereof. The fiber coating may be electrostatically charged. The coated electrospun fibers can be polymeric fibers or polymeric fibers loaded with biocides such as silver, copper oxide, and the like. The second filter layer is a melt-blown microfiber nonwoven layer; the third filter layer is a spunbond microfiber nonwoven layer. The coating can reduce the gaps among the fibers to achieve a protection level above N95. The three filter layers can intercept the particles flowing in the gas through common mechanical action mechanisms such as inertial deposition, gravity deposition, Browner diffusion and the like, and can realize the purification of the air and the killing of common bacteria and viruses through the electrostatic action, so that the whole filter screen has the characteristics of low resistance, high efficiency, dust removal, sterilization and the like
Because the gauze mask in this embodiment is connected with the oxygen therapy apparatus, the pressure intensity of gauze mask inboard is great, in order to guarantee to dress firm, preferring to use the bandage 2 of wear-type. The check valve 5 is a check valve 5 with a check membrane commonly used in existing masks, and is not described in detail in this embodiment.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that other variations and modifications may be made without departing from the spirit and scope of the present invention, and the scope of the present invention is intended to be protected by the following claims.
