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.

Described PET thin film is placed between semicircle groove and convex moulding, after being tightened, buckles by semicircle groove and convex moulding, by base, PET thin film and upper cap, is assembled successively and is formed artificial tympanum protection mechanism integral body.
The implementation method of described artificial tympanum protection mechanism, is characterized in that, comprises the steps:
A) PET thin film is placed between semicircle groove and convex moulding, the top semicircle groove of base is matched with the convex moulding of the contact position of upper cap cylinder upper base inwall;
B) make PET thin film center partly form tensioning state; after being tightened by semicircle groove and convex moulding, buckle; rely on friction self-locking and two kinds of forms of double buckle to act on simultaneously; PET thin film is entirely stretched in the middle of the through hole of base central through hole and upper cap, thereby forms the artificial protecting film in device.
The tapering of the seat body cone of base is 5 degree, and the inner chamber tapering of cylinder upper base inwall bottom is 5 degree.
Beneficial effect of the present invention: the through hole as audition passage is completely cut off to protecting film with PET thin film; make it have following characteristics: simple in structure; easy for installation; utilize the feature of PET membrane tension high conformity; realization is under high hydraulic pressure, hyperbar operation, high noise environments; can avoid high pressure directly to impact operator's tympanum (tympanum), can retain again the effect of unimpeded audition passage.Applicable to production in enormous quantities, cost is lower.
