Abstract
Description
Technical Field
[0001] The invention relates to a method for using a portable device for preventing cross contamination of masks when they are temporarily placed. Background Art
[0002] Wearing masks to prevent COVID-19 infection has been advocated by countries around the world. In addition to using special recycling containers to recycle discarded masks, reducing unnecessary mask waste is particularly important for reducing environmental pollution. The recommended wearing time for ordinary surgical medical masks and N95 masks is 4 hours and 8 hours, respectively. When the demand for masks increases significantly or the supply is insufficient at the beginning of the outbreak, it is usually acceptable to appropriately extend the use time and limited reuse. In addition, in work and life when wearing masks, in common situations such as temporary drinking, eating and changing clothes, it is often necessary to temporarily remove the mask and store it properly.
[0003] How to properly place a temporarily removed mask has always been a challenging problem. Respiratory pathogens may exist on the inside or outside of a used mask. When a mask is reused, these pathogens may cause infection through hand or skin infection, or contact with mucus after ingestion. If a worn mask is placed randomly, it will cause the mask to contaminate the surrounding clean environment. Studies have shown that the survival duration of the new coronavirus on different surfaces ranges from 2 hours to 9 days, and it can survive on the surface of a mask for 7 days. Placing the mask (outside or inside) directly on a table or other surface will undoubtedly cause the pathogens on the mask to contaminate the surrounding environment. On the other hand, if the inner side of a sterile mask is placed directly on an unclean surface, the mask may be contaminated, causing the wearer to inhale exogenous pathogens when it is worn again. Summary of the invention
[0004] The present invention provides a portable device for preventing cross contamination when a mask is temporarily placed. The device is easy to operate, compact, and takes up little space. When in use, the device only needs to be placed on a flat surface, and is easy to carry and place. The device prolongs the service life of the mask, improves the utilization rate of the mask, and reduces unnecessary waste of the mask. The device is truly "small in size, big in function", eliminates the worry of secondary contamination when the mask is temporarily placed, is conducive to the economical use of the mask, and provides strong support for reducing environmental pollution caused by mask consumption.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is:
[0006] A portable device for preventing cross contamination of masks when they are temporarily placed, characterized in that: the interior of a main body tube is hollow, a plurality of circular holes are arranged at the top of the main body tube, a self-expanding rubber pad is arranged at the bottom of the main body tube, a plurality of base brackets are arranged on the circumference of the bottom of the main body tube, the self-expanding rubber pad is used for the base bracket to open, and a plurality of slideways are arranged on the outer wall of the main body tube;
[0007] The outer sleeve is hollow inside, and a plurality of radial limiting beams are arranged at the top of the outer sleeve, and an elastic bracket is arranged on the limiting beam. The initial state of the elastic bracket is open, and a pair of elastic branches are arranged at the top of the elastic bracket, and an elastic hook is arranged on the elastic branch;
[0008] The limiting beam is slidably embedded in the slideway, so that the outer sleeve is slidably sleeved on the outer wall of the main body tube. The outer sleeve can slide longitudinally, and the outer sleeve controls the opening and closing of the base bracket and the elastic bracket through longitudinal sliding.

[0024] like Figures 1 to 11 A portable device for preventing cross contamination of masks when they are temporarily placed is shown, characterized in that: the interior of the main body tube 1 is hollow, a plurality of circular holes 3 are arranged at the top of the main body tube 1, a self-expanding rubber pad 6 is arranged at the bottom end of the main body tube 1, a plurality of base brackets 5 are arranged on the circumference of the bottom end of the main body tube 1, the self-expanding rubber pad 6 is used for the base bracket 5 to open, and a plurality of slideways 4 are arranged on the outer wall of the main body tube 1.
[0025] The outer sleeve 2 is hollow inside, and a plurality of radial limiting beams 7 are arranged at the top of the outer sleeve 2. An elastic bracket 8 is arranged on the limiting beam 7. The initial state of the elastic bracket 8 is open. A pair of elastic branches 9 are arranged at the top of the elastic bracket 8. An elastic hook 10 is arranged on the elastic branch 9. The elastic hook 10 is used to hang the ear hanging part of the mask to prevent the mask from contacting the external environment and prevent cross contamination.
[0026] The limiting beam 7 is slidably embedded in the slideway 4, so that the outer sleeve 2 is slidably mounted on the outer wall of the main tube 1. The outer sleeve 2 can slide longitudinally. The outer sleeve 2 controls the opening and closing of the base bracket 5 and the elastic bracket 8 by longitudinal sliding. The elastic bracket 8 passes through the circular hole 3, so that the top of the elastic branch 9 is above the top of the main tube 1. The elastic hook 10 can prevent the elastic branch 9 from sliding into the interior of the main tube 1.
[0027] In the embodiment, the outer sleeve 2 is sleeved on the outer wall of the main tube 1, and the limiting beam 7 is slidably embedded in the slideway 4. The outer sleeve 2 can slide longitudinally on the outer wall of the main tube 1. When not in use, the outer sleeve 2 is located at the bottom of the main tube 1. The outer sleeve 2 wraps the top of the base bracket 5, so that the base bracket 5 is in a closed state, and the elastic bracket 8 can be pulled into the main tube 1 through the circular hole 3. Through the elastic hook 10, the top of the elastic branch 9 is above the top of the main tube 1 to prevent it from completely sliding into the main tube 1.
[0028] When in use, the outer sleeve 2 is slid upward along the outer wall of the main tube 1, driving the elastic bracket 8 to move upward together, and the outer sleeve 2 slides away from the top of the base bracket 5. Through the elasticity of the self-expanding rubber pad 6, the base bracket 5 can be in an open state, which is convenient for standing on a desktop or other plane. The outer sleeve 2 slides to the top of the main tube 1. Due to the limitation of the limiting beam 7, the outer sleeve 2 is prevented from sliding out of the top of the main tube 1. At this time, the elastic bracket 8 passes through the circular hole 3 and is in an open state. Due to the open state of the elastic bracket 8, the outer sleeve 2 is prevented from sliding downward. The elastic hook 10 is used to hang the ear hanging part of the mask, so that the mask is suspended to avoid contact with the external environment and prevent cross contamination.
[0029] After use, the outer sleeve 2 is slid downward to the initial position, and the base bracket 5 and the elastic bracket 8 are in a closed state.
[0030] Advantages of the present invention:
[0031] It is easy to operate, compact, and takes up little space. When in use, you only need to find a flat surface to place it, which is easy to carry and place. It improves the utilization rate of masks and reduces unnecessary waste of masks. It is truly "small size, big function". It eliminates the worries of secondary pollution when temporarily placing masks, is conducive to the economical use of masks, and provides strong support for reducing environmental pollution caused by mask consumption.
[0032] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.
