Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a new type of blood collection tube. Background Art

[0002] Peripheral blood refers to blood from the fingertips and earlobes. It is mostly used for some simple and easy tests that use a small amount of blood and have rapid measurements. The more commonly used items include routine blood tests, blood type, micro-method or rapid blood sugar and uric acid tests. In the process of taking peripheral blood, you first need to use a peripheral blood collection needle to pierce your finger, then use a blood collection pipette to absorb the blood overflowing from the fingertips, and then squeeze the blood into a collection tube.

[0003] The above operation method requires concentration on inserting the tip of the blood collection tube into the test tube, which involves an alignment process. Moreover, many components are required, the degree of integration is low, and multiple taking and discarding actions are required. The process is cumbersome, which affects work efficiency and is not practical. Utility Model Content

[0007] When using the above-mentioned new blood collection tube, the needle is pointed towards the fingertip and then the sealing plug needle is inserted inward into the opening of the tube body. The inclination angle of the drainage hose is adjusted by the positioning structure. Then, the patient's fingertips are held with one hand and squeezed repeatedly. At the same time, the tube body is held with the other hand and the thumb is used to repeatedly squeeze the extrusion head. The blood overflowing from the fingertips is sucked into the tube body through negative pressure. After the appropriate amount is sucked in, the sealing plug is pulled out and discarded, and then the sealing cap is buckled on the open end of the tube body to complete the collection.

[0008] Preferably, a plurality of pinching grooves are provided on the circumferential surface of the sealing plug.

[0009] Preferably, the drainage hose is 2-4 cm long and is a transparent rubber hose.

[0010] Preferably, the positioning structure comprises an iron wire which is integrally formed with the outer wall of the drainage hose and is located at one end close to the sealing plug.

[0011] Preferably, an annular groove is provided on the outer wall of the tube body on the side close to the opening, a ring sleeve is sleeved in the annular groove, and one side of the ring sleeve is connected to the sealing cover through a soft film.

[0012] Preferably, the tube body is made of transparent plastic material and has scales on its side walls. A plurality of sealing rubber rings that abut against and fit against the inner wall of the cover are fixedly connected to the outer wall of the open end of the tube body.

[0013] Preferably, a puncture rubber pad is provided in the middle through hole of the sealing cover.

[0014] The beneficial effects are:

[0015] By pricking the needle toward the fingertip, and then inserting the sealing plug needle inward into the opening of the tube body, adjusting the inclination angle of the drainage hose through the positioning structure, and then holding the patient's fingertip with one hand and squeezing it repeatedly, while holding the tube body with the other hand, the thumb repeatedly squeezes the squeezing head, and the blood overflowing from the fingertip is sucked into the tube body through negative pressure. After the appropriate amount of blood is sucked in, the sealing plug is pulled out and discarded, and then the cap is buckled on the open end of the tube body. The whole operation process is quick and convenient, with a high degree of integration, and at the same time avoids the alignment operation process, thereby improving work efficiency and practicality.
