Safely Inject is a special injection tube which can be automatically stopped after intravenous injection.
Intravenous injection in the hospital must be stopped in time when it almost completes. Otherwise, the residual air left in the tube will be injected into the patients body after liquids injection, which can be at a substantial risk (too much air into the intravenous may cause sudden death.)
Safely Inject can stop injecting automatically when there arent liquids left in the injection tube. This design will be especially effective for undeveloped areas where lack of health care conditions in order to avoid causing of medical dangerou.
