The specific dimensions adopted in the present embodiment are only for illustrating the technical solution, and do not limit the protection scope of the present utility model.

The embodiment of the utility model discloses an autogenous cutting hole retainer. As shown in fig. 1 and 2, the autogenous cutting hole retainer comprises a sleeve 1 and an end cover 3, one end of the sleeve 1 is provided with a soft backing plate 4 attached to the neck, the other end is provided with an end pipe 2 which is mutually communicated, and the end pipe 2 and the sleeve 1 are coaxially distributed.

As shown in fig. 1 and 2, an annular first clamping groove 21 is formed in the inner wall of the end pipe 2, at least two second clamping grooves 22 which are symmetrical along the center of the axis of the end pipe 2 are formed in one end, far away from the sleeve 1, of the end pipe 2, and the second clamping grooves 22 are communicated with the first clamping groove 21. The end face of the end cover 3 is vertically provided with a connecting pipe 31, the connecting pipe 31 is inserted in the end pipe 2 and seals the end pipe 2, the side wall of the connecting pipe 31 is provided with clamping blocks 32 corresponding to the two second clamping grooves 22, and the clamping blocks 32 are tightly matched with the first clamping grooves 21. The end cover 3 is provided with a plurality of air grooves 33 communicated with the inside of the connecting pipe 31, the air grooves 33 are circumferentially and equidistantly arranged along the axis of the end cover 3, and one side of the end cover 3 facing the connecting pipe 31 is provided with a film 34 for shielding the air grooves 33.

The membrane 34 may be connected to the end cover 3 at the middle part, and the membrane 34 has a certain elasticity, and in a natural state, the membrane 34 is kept flat on the end cover 3 to block each air groove 33, so that an operator can jack up the outer peripheral part of the membrane 34 from the outside of the end cover 3.

When a patient needs to speak, the clamping block 32 corresponds to the second clamping groove 22, then the connecting pipe 31 is moved into the end pipe 2, the clamping block 32 is driven to be inserted into the first clamping groove 21, the end cover 3 is rotated, the clamping block 32 moves along the first clamping groove 21 so as to be staggered with the second clamping groove 22, at the moment, the clamping block 32 abuts against the inner wall of the first clamping groove 21, the relative rotation of the connecting pipe 31 is limited, the outer wall of the connecting pipe 31 abuts against the inner wall of the end pipe 2, the end pipe 2 is closed, the end pipe 2 is not required to be always covered by the patient, and the use is convenient and quick.

As shown in fig. 2, since the film 34 is disposed inside the end cap 3, the air flow ejected from the inside of the connection pipe 31 blows the film 34, so that the film 34 is kept flat and covers the air groove 33, and the operator can insert a pipe from the outside, lift the film 34 from the air groove 33 by the pipe, and further extend into the connection pipe 31, and perform operations such as oxygen transportation by the pipe. When the operator pulls out the catheter, the membrane 34 is restored under the action of the self elastic force, and the air groove 33 is covered again.

Be equipped with on the end cover 3 along the hem 35 of end cover 3 circumference distribution, be equipped with first anti-skidding line 351 on the hem 35, end pipe 2 lateral wall is equipped with two otic placodes 24, and the one end that end pipe 2 was kept away from to two otic placodes 24 all is equipped with second anti-skidding line 241, increases the frictional force between finger contact when first anti-skidding line 351 and second anti-skidding line 241 do benefit to the operator to hold between the fingers, makes things convenient for the operator to twist end cover 3. The side wall of the end pipe 2 is provided with an annular groove 23, and the groove 23 provides a basis for an operator to tie the end pipe 2 by using a belt for fixing.

The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
