Description

A vacuum sealed sampling tube

Technical Field

The utility model belongs to the technical field of sampling tubes, in particular to a vacuum sealed sampling tube.

Background Art

A vacuum sampling tube is a medical device used to collect and preserve blood samples. When the vacuum sampling tube leaves the factory, the tube body is evacuated. The principle of blood collection is to use the vacuum state inside the tube body to suck blood into the tube body, and the needle of the blood collection needle connected to the sampling tube is inserted into the vacuum tube. Under the action of the negative pressure in the sampling tube, the blood flows into the sampling tube body through the catheter, thereby achieving the effect of blood collection. However, in actual use of the vacuum sampling tube in the prior art, when medical staff completes blood collection, they need to pull the needle out of the rubber block with force. At this time, when the medical staff uses greater force, the sampling tube will shake while pulling out the needle, which can easily spill blood, and the needle will leave holes in the rubber block. When collecting blood, medical staff often need to collect blood from multiple sampling tubes before they can test them together. The blood is easily contaminated, so it needs to be improved.

The working principle and use process of this utility model:

First, the medical staff can tear off the film 11, and connect the needle of the blood collection needle to the sampling tube body 1, penetrate the fixing block 4 and the rubber block 3 into the interior of the sampling tube body 1, so that the blood flows into the sampling tube body. The medical staff can read the amount of blood inside the sampling tube body 1 through the scale 10. After pulling out the part of the blood collection needle connected to the human body, the medical staff can place the sampling tube body 1 on the platform, and press the base 6 with their fingers, and pull out the needle inside the sampling tube body 1 at the same time.

Then, the medical staff can rotate the base 6 to disengage the mounting block 5 from the inside of the circular ring block 7, and remove the base 6 and the plastic block 9 as a whole. Then, the medical staff passes the plastic block 9 through the inside of the fixed block 4, and rotates the base 6 to rotate the circular ring block 7, thereby fixing it to the outside of the fixed block 4, and allowing the plastic block 9 to penetrate into the inside of the rubber block 3.
