Background
In the daily medical activities such as transfusion, blood transfusion, hemodialysis, blood drawing, blood donation and the like, medical staff must use a disposable needle with a liquid guiding pipe, and one needle needs to be punctured into a blood vessel of a patient for transfusion or blood drawing, so that when the patient suffers from a blood infectious disease, the medical staff can increase the probability of infection.
When the existing disposable needle head with the drainage tube is used, a puncture needle is inevitably contacted with blood of a patient, after corresponding medical activities are completed, the puncture needle is required to be pulled out, and since the puncture needle is infected by the blood of the patient, the puncture needle cannot puncture a third person, otherwise, the punctured third person can be cross-infected with the patient. In the actual medical activity, when a puncture needle is used for puncturing a patient, the pipe sleeve on the needle head is generally discarded because of no place for placement, when the puncture needle is pulled out of a blood vessel of the patient, the puncture needle is prevented from being exposed outside, the puncture needle is ensured not to puncture other people, a protective measure is required to be taken, the original hollow pipe sleeve is generally adopted for sleeving, but in the actual work, the original hollow pipe sleeve cannot be found, or even if the hollow pipe is found, the puncture needle cannot be used for puncturing the other hand of a nursing staff when the hollow pipe is covered, particularly in the busy operation, the puncture needle cannot be used for puncturing the other hand of the nursing staff, therefore, medical staff engaged in the work are very easy to be invaded by accidental blood-borne disease cross infection, particularly nurses, the risk of the nurses in the nursing work is greatly increased, and meanwhile, the virus propagation probability is improved. According to statistics of relevant test data, when the hollow tube is sleeved, the proportion of accidental pricks of medical staff is extremely high, and particularly the proportion of accidental pricks of the medical staff in departments such as an emergency room, an outpatient infusion room, a hemodialysis room, an ICU and the like is higher. Therefore, many medical staff are reluctant to engage in the medical and nursing work of patients with blood-borne diseases (such as hepatitis B, hepatitis C, syphilis, AIDS, etc.). At present, the medical staff who are engaged in the work have great mental stress in the actual work and have anxiety and panic in the mind. On the other hand, the treatment of needles used by patients with these blood-borne diseases (such as hepatitis B, hepatitis C, syphilis, AIDS, etc.) also has the risk of infecting others. How to protect the working safety of medical staff and prevent the medical staff from being infected when the medical staff is engaged in the work is a technical problem which is expected to be solved but not solved by a medical system for a long time.
