Artificial eardrum protecting mechanism and implementation method thereof

Abstract

The invention relates to an artificial eardrum protecting mechanism and an implementation method thereof. The artificial eardrum protecting mechanism comprises a base, a PET (polyethylene terephthalate) film and an upper cap. The base is conical cavity. A central through hole is reserved at the center of the base. A semicircular groove with a snap fastener structure is machined at the upper edge of the central through hole. The upper cap is cylindrical cavity, a through hole is reserved at the upper bottom center of the cylinder, an inner cavity below the inner wall of the cylinder upper bottom is conical, and a semicircular flange with a snap fastener structure is machined on the inner wall plane of the upper bottom of the upper cap. The PET film is disposed between the semicircular groove and the semicircular flange to allow the central part of the PET film to be in a tensioning state, and the PET film is tightened and fastened by the semicircular groove and the semicircular flange to form an artificial protecting film of the mechanism. The PET film is used as through hole isolation protecting film of a hearing passage, good tensioning consistency of the PET film is utilized, high pressure is prevented from impacting eardrums of operators directly under high water pressure, high air pressure and high noise environments while the smooth hearing passage can be maintained.

Description

technical field [0001] The present invention relates to the technology of human eardrum protection earplugs, in particular to an artificial eardrum protection mechanism and its realization method. In the environment of operation, land high-pressure operation, and high noise, human eardrum protection earplugs are used to protect the safety of the staff's eardrums. Background technique [0002] Under the environment of high water pressure underwater, high air pressure on land, high noise and other environments, the environmental pressure will cause damage to the eardrum of the staff. In order to avoid high pressure directly impacting the eardrum (tympanic membrane) of the operator, it will cause irreparable damage. The method of wearing earplugs is usually adopted to protect the staff's eardrum safety. Existing earplugs are usually molded by silica gel or plastic, and the pressure is reduced through the earplugs, and a hearing channel can also be formed through the sm...

Problems solved by technology

[0003] Although the existing earplugs can reduce the damage to the operator's eardrum (tympanic membrane) in high water pressure, high air pressure, and high noise environments, due to the existence of the small hole in the center of the earplug, the transparent small hole fails to seal the eardrum (tympanic membrane) It is isolated from the outside, so it cannot completely prevent water and air from pouring into the ear through small holes under high pressure, so the existing earplugs cannot completely avoid high pressure from directly impacting the operator's eardrum (tympanic membrane). The hearing channel of the operator is lost. Therefore, it is necessary to transform and design a new artificial eardrum protection mechanism structure through technical transformation, and apply it to human eardrum protection earplugs to achieve high water pressure, high air pressure, and high noise environments. It can avoid the direct impact of high pressure on the operator's eardrum (tympanic membrane), and can also retain the effect of unimpeded hearing channels. Through technical transformation, the shortcomings of the existing technology are overcome. There is no such device on the market that can protect the human eardrum (tympanic membrane). There is no relevant report in the literature
