Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a vaccine patch for protecting wounds after injection. Background Art

[0002] The vaccination, hygiene and efficiency of children's vaccines have always been the focus of people's attention. The three major problems that arise in the process of children's vaccination are: 1. Children will experience strong pain during the vaccination process, which makes the injection inefficient; 2. Children's physical condition needs to be monitored in real time within 24 hours after vaccination, which is an unnecessary extra consumption and burden for parents; 3. There are many types of vaccination equipment and the operation is complicated, and it is often necessary to go to the hospital for time-consuming pre-vaccination waiting.

[0003] The above problems are well solved through the use of vaccine patches in the medical process. However, although the vaccine patches can reduce pain, they will still leave pinholes on the skin after use. When the pinholes on the skin are not completely healed, the wounds exposed to the air are susceptible to infection and cannot provide effective follow-up protection for the user. For this reason, we propose a vaccine patch that protects wounds after injection.

[0004] The purpose of the present invention is to provide a vaccine patch for protecting wounds after injection, so as to solve the problems raised in the above background technology.
