Background

Hand washing is an indispensable thing in daily life, and especially for doctors who need to perform operations or examinations, hand washing and disinfection are more important ways to protect themselves and others.

Currently, in the medical field, there are two main ways for a doctor to disinfect the hands:

1. washing hands with a disinfectant hand sanitizer;

2. spraying or smearing the hand with the washing-free disinfectant, and rubbing the hands with each other.

For the first, the doctor needs to go to the adjacent hand washing sink, wash his hands with the hand sanitizer, and rinse with running water. This can take a certain amount of time, especially in some emergency situations, where valuable rescue time is lost to and from the sink. Meanwhile, subjective factors of doctors during hand washing may cause poor hand washing and disinfecting effects. From the perspective of water resource protection, the water consumption of the common running water hand washing mode is large.

The second hand washing mode is greatly improved compared with the first hand washing mode, a doctor only needs to press a container nozzle for containing disinfectant, the disinfectant can be extruded out of the palm of the hand, and then hands rub each other to finish hand disinfection work. This approach has certain limitations, however, such as the possibility of contamination of the nozzle by the physician pressing on the container nozzle; the excessive pressing force can cause the waste of disinfectant, and the insufficient pressing force can cause the poor disinfection effect; uneven application of the disinfecting liquid may also lead to poor disinfection.
