Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 and give, including big right horn plate 1 of a left side, annular spout 2 has been seted up to horn plate 1 right side internal surface, 2 internal rotations of spout are connected with about axial semi-ring shape piece 3, be equipped with in the semi-ring shape piece 3 can swing from beginning to end drum 4, axial cylinder piece 5 about drum 4 sliding connection has, the coaxial pjncture needle 6 that is equipped with of 5 left ends of cylinder piece, the drum 4 is run through to 6 left ends of pjncture needle, the round hole 7 that link up about drum 4 right-hand member was seted up, 5 right sides of cylinder piece are equipped with the drain pipe 8 with pjncture needle 6 intercommunication, 8 right-hand members of drain pipe stretch out round hole 7 and are equipped with bottle lid 9, threaded.

In order to enable the cylinder 4 to swing back and forth, the upper end and the lower end of the cylinder 4 are respectively provided with a connecting block 11, and the upper end and the lower end of the semi-annular block 3 are respectively in rotary connection with the connecting blocks 11 on the corresponding sides through pin shafts.

In order to enable the cylindrical block 5 to slide left and right, a plurality of connecting rods 12 are uniformly distributed at the right end of the cylindrical block 5 along the circumferential direction of the cylindrical block, and the right ends of the connecting rods 12 penetrate through the round holes 7 and are provided with push plates 13.

For better drainage effect, the upper end of the bottle cap 9 is provided with an air inlet pipe 14, the free end of the air inlet pipe 14 is provided with an air bag 15, and the right end of the air bag 15 is provided with an air outlet pipe 16.

In order to prevent the air in the air bag 15 from entering the drainage bottle 10, a one-way air inlet valve 17 with an opening facing the air bag 15 is arranged in the air inlet pipe 14.

In order to prevent outside air from entering the air bag 15, the air outlet pipe 16 is provided with a one-way air outlet valve 18 which is opened far away from the air bag 15.

In order to make the trumpet-shaped plate 1 fit with the skin of a patient, the left end of the trumpet-shaped plate 1 is provided with an arc-shaped groove 19.
