Technical Field

The utility model relates to the technical field of medical equipment, in particular to a multi-end easy-to-fix blood taking needle.

Background

Blood tests are a routine and important in vitro detection means required for disease diagnosis. When blood is collected, medical staff who needs to perform blood collection need to find the blood vessel position to puncture firstly, after the puncture is successful, the blood collection needle is fixed by using an adhesive tape or a specific gesture, and then the blood collection needle connected with the rear end of the blood collection needle is inserted into the negative pressure catheter to take a certain amount of blood for inspection. And a plurality of test projects are needed for new patient admission, so the number of the blood sample collecting tubes is more, and the average number of the blood sample collecting tubes is 8-12.

Although the blood taking needle used in the prior art can meet the requirements of blood collection of hospitals, the following defects are found in the practical application process:

1. the blood collection needle used in the prior art can puncture the bottle stopper of the collection tube for 5 times at most due to safety, otherwise, blood leakage condition can occur to increase blood infection, so that after the blood collection needle reaches the upper collection limit, medical staff is required to prick and put the tourniquet again, and a new blood collection needle is used for carrying out a round of blood collection flow, so that the time required for blood collection is increased, discomfort of a patient is increased due to repeated needle insertion, and even the problem of repeated puncture of the blood collection needle can cause influence on the quality and effect of blood collected subsequently.

2. In the process of collecting blood, a certain time is needed, the blood taking needle is required to be fixed so as not to deviate, a small amount of blood is collected by a single person and is pressed in a short time by a general medical staff, but when more blood samples are required to be collected, the medical staff is often required to carry a blood taking needle after the medical adhesive tape is fixed and pricked into a blood vessel, and the blood taking needle still can deviate or deviate when the medical staff takes or tears the medical adhesive tape.
