[0021] Such as Figures 1-3As shown in the figure, an embodiment of the present utility model provides a disposable portable sterile cotton swab for ophthalmology, which includes a tube body 1, a rubber head 2 provided at one end of the tube body 1 (the rubber head is firmly bonded), and a moisture absorption part 3 provided at the other end of the tube body 1. The moisture absorption part 3 is connected to a control unit 4 that can accommodate the moisture absorption part 3 into the tube body 1. The control unit 4 is arranged in the tube body 1 between the rubber head 2 and the moisture absorption part 3.

[0022] In this embodiment, the control unit 4 includes a support rod 41 and a switch 42. One end of the switch 42 is connected to the middle of the support rod 41, and the other end extends out of the tube body 1. An opening for the switch 42 to slide is provided on the tube body 1. Plugs 43 that slide along the inner wall of the tube body 1 are respectively provided at both ends of the support rod 41. A pressure relief hole 44 is provided on one side of the tube body 1 at the rubber head 2 end, and the moisture absorption part 3 is fixed on the plug 43. The plug 43 is a rubber plug, and the rubber plug is made of medical silicone rubber, which has good biocompatibility, no irritation, no toxicity, and no allergic reaction to human tissues. It has good physical and chemical properties, can maintain its original elasticity and softness during contact with body fluids and tissues, and is not degraded. The plug 43 is firmly bonded to the moisture absorption material.
