The peripheral side wall of the limit piece 20 is in sliding abutting connection with the peripheral side wall of the limit groove 21.
The support block 10 and the support table 11 are provided with a rectangular elastic film 22 at a side far away from the arc groove, and in this embodiment, the elastic film 22 may be made of TPE. One end of the elastic membrane 22 in the length direction is fixedly arranged at the position, close to the supporting block 10, of the side wall of the guide piece 2 relative to the second arc groove 4 and the side wall of the attaching piece 1 relative to the first arc groove 3 through medical glue, and the other end of the elastic membrane 22 in the length direction is fixedly arranged at the position, close to the supporting table 11, of the side wall of the first fixing piece 5 relative to the first arc groove 3 and the side wall of the second fixing piece 6 relative to the second arc groove 4 through medical glue.
The implementation principle of the embodiment 2 is as follows: when the operation of cell collection is performed, it is necessary to rotate the collector from time to time so that the collector can sufficiently collect the cells at the place to be collected. When the collector needs to be rotated, firstly, the knob 15 moves in the direction away from the limit groove 21, the knob 15 drives the rotating shaft 14 to move in the same direction, the rotating shaft 14 drives the limit piece 20 to slide in the limit groove 21, when the limit piece 20 is abutted against the side wall of the limit groove 21, which is close to the knob 15, the first convex strips 16 are separated from the clamping state of the grooves 18, the smooth parts 19 on the rotating shaft 14 are positioned at the positions close to the first convex strips 16, at the moment, the knob 15 is rotated, the knob 15 drives the rotating shaft 14 to rotate in the first through hole 12, and the rotating shaft 14 is clamped with the second convex strips 17 through the grooves 18, so that the guide piece 2 and the attaching piece 1 rotate in the same direction along with the rotating shaft 14. When the guide piece 2 and the attaching piece 1 rotate to a required angle, the knob 15 can be moved towards the direction where the limit groove 21 is located, the knob 15 drives the rotating shaft 14 to move in the same direction, and the limit piece 20 on the rotating shaft 14 moves in the direction away from the supporting table 11 in the limit groove 21, so that the limit piece 20 is separated from a state of abutting with the side wall of the limit groove 21, which is close to the knob 15. The groove 18 is in sliding clamping connection with the first raised strip 16, so that the guide piece 2 and the second fixing piece 6 are relatively fixed, and the attaching piece 1 and the first fixing piece 5 are relatively fixed; at this time, the cell collection operation can be continued.
When the angle of the guide piece 2 and the attaching piece 1 in the body of the person to be collected is adjusted, the elastic membrane 22 is abutted against the skin at the incision of the person to be collected, so that the probability that the skin at the incision of the person to be collected is extruded by a gap between the supporting table 11 and the supporting block 10 to cause damage when the guide piece 2 and the attaching piece 1 are rotated is reduced, and the protection of the skin protector to the person to be collected is facilitated to be improved.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
