A protective sheath for a disposable surgical scalpel includes at least three modes of operation, (i) a protective mode, (ii) an open mode, and (iii) a permanently locked mode. In the open mode, a locking strip of the scalpel handle resides in one opening of the sheath to keep the sheath substantially immobile during use of the scalpel blade. In the protective mode, the locking strip resides in a second opening of the sheath to keep the sheath substantially immobile when the scalpel blade is not in use. In the permanently locked mode, a button connected to the sheath is depressed into the second opening and engages the locking strip, thereby preventing the blade from being used and allowing the scalpel to be safely disposed.

In the protected configuration the needle shield is prevented from sliding proximally along the needle a sufficient distance to expose the needle tip.

The manufacturing method for the air intake apparatus has a holding-portion forming step, a temporarily fixing step, and a joining step. In the holding-portion forming step, a holding portion is formed. In the temporarily fixing step, the porous member is held by the holding portion.

Thus, an air intake apparatus, in which the opening is reliably covered with the porous member, can be manufactured. In the air intake apparatus manufactured by this manufacturing method, a peripheral portion of the porous member is doubly sealed with the holding portion that is an outer edge part of the opening. Consequently, the opening is reliably covered with the porous member, so that intake noise is reliably reduced.
