Problems solved by technology
As for blood sampling, at present, the blood collection bag and the vacuum sampling tube are mainly operated separately. Since the blood collection operation and the sampling operation are carried out separately, it is easy to cause the risk of contamination of the blood sample during the sampling operation, thereby affecting the follow-up of the blood sample. In addition, because the blood collection bag and the vacuum sampling tube are used together, although identification labels are pasted on the blood collection bag and the vacuum sampling tube, it is inevitable that the medical staff will mistakenly paste them during the actual operation. This also brings various hidden dangers to the subsequent processing of blood samples

Embodiment Construction
[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0017] Such as figure 1 The shown integrated vacuum sampling device includes a vacuum sampling tube 11, a sampling needle 16, a connecting cap 13 and a housing 14. The connecting cap 13 and the housing 14 are both hollow cavity structures, and at the entrance of the vacuum sampling tube 11 The piercing cap 12 is sealed and connected, the sampling needle 16 is fixedly connected to the needle seat 15, and the tip of the sampling needle 16 pierces through the piercing cap 12 and is located in the inner cavity of the vacuum sampling tube 11. Between the sampling needle 16 and the piercing cap 12 form...

The invention provides an integrated vacuum sampling device. The device comprises a vacuum sampling tube (11) and a sampling needle (16). An inlet portion of the vacuum sampling tube (11) is connected with a puncture cap (12) in a sealed mode, the sampling needle (16) is fixedly connected to a needle seat (15), and the tip of the sampling needle (16) pierces the puncture cap (12) and then is located in an inner cavity of the vacuum sampling tube (11). A seal structure is formed between the sampling needle (16) and the puncture cap (12). When the integrated vacuum sampling device is used for blood sampling, the inlet portion of the vacuum sampling tube is connected with the puncture cap in a sealed mode, and the seal structure is further formed between the sampling needle and the puncture cap, so that a blood sample entering the vacuum sampling tube is taken in a completely sealed state. The sampling operation is easy and fast; when the blood sample is taken, the pollution risk is effectively reduced, and the mistake to confuse reserved samples do not occur, and it is guaranteed that the blood sample can be taken safely and reliably.
Description
technical field [0001] The invention relates to the technical field of safe sampling for blood transfusion, in particular to an integrated vacuum sampling device matched with a blood collection bag. Background technique [0002] During the clinical blood transfusion operation, it is usually required to perform blood sampling at the same time as the blood collection operation. As for blood sampling, at present, the blood collection bag and the vacuum sampling tube are mainly operated separately. Since the blood collection operation and the sampling operation are carried out separately, it is easy to cause the risk of contamination of the blood sample during the sampling operation, thereby affecting the follow-up of the blood sample. In addition, because the blood collection bag and the vacuum sampling tube are used together, although identification labels are pasted on the blood collection bag and the vacuum sampling tube, it is inevitable that the medical staff will mistaken...
