The invention discloses a label-free blood sample test tube based on physical examination blood collection and a use method thereof, belonging to the field of medical blood collection test tubes, and a label-free blood sample test tube based on physical examination blood collection and a use method thereof. There is a pressing thumb groove, the pressing thumb groove and the tube body are integrated structure, and the marking pressure bag is embedded in the pressing thumb groove, which can realize the integrated design of the inner double display arc plate and the tube body of the blood sample test tube, and cooperate with the marking pressure bag at the same time The setting can effectively protect the inner double-display arc-shaped board, so that it is not easy to cause it to fail or cause marks on it due to accidental touch before use, which will affect the later use. Compared with the existing technology, it effectively reduces the medical staff The workload during blood collection for physical examination effectively improves work efficiency, and effectively avoids the confusion of blood samples caused by label drop, and effectively avoids the deviation of later physical examination results.

The present invention relates to an artificial blood vessel and its production method. Its main technical scheme lies in that the outer wall of its vessel blank has several coils which are spaced and made up by warp yarn in the taking-out mode, and the coils are arranged on the outer wall of vessel blank in spiral form or network form, and elastic band is passed through the coils, and positioned on the outer wall of the vessel blank by means of coils. Said invented blood vessel can raise anti-bending strength and anti-compressing strength of artificial blood vessel.

A simple and robust on-chip blood plasma separation device is provided. The device is configured to integrate with downstream detection modules and provides sample-to-answer microfluidic POC diagnostics devices.

The invention relates to the field of medical treatment, in particular to a hematology-department blood-transfusion-tube blocking-free and anti-caking structure and a method. The hematology-department blood-transfusion-tube blocking-free and anti-caking structure comprises an upper connecting tube, a connecting cover is arranged at the lower end of the upper connecting tube, the upper connecting tube is surrounded by the connecting cover, the connecting cover comprises a wide upper end and a narrow lower end and is a gradually-narrowed arc-shaped shell, and a first-stage filtering structure in the middle is connected onto the arc-shaped shell through a side filtering ring and comprises a lower channel opening; a middle filtering net is arranged in the middle of the lower channel opening and faces a first-stage medicine discharging opening in the lower portion of the upper connecting tube, an arc-shaped structure is arranged above the first-stage filtering structure and surrounds the first-stage medicine discharging opening, and an overflowing route changing opening is formed between the first-stage medicine discharging opening and the arc-shaped structure. In the prior art, direct blocking is generated and dredging cannot be conducted, or dredging cannot be conducted after blocking, or impurities enter the human body and cause injuries. According to hematology-department blood-transfusion-tube blocking-free and anti-caking structure and the method, implementation is safer.
