Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and more specifically, particularly relates to a blood collection tube which is convenient for classification. Background Art

[0002] During the blood collection process at the blood station, medical staff need to draw the volunteer's blood into a blood collection tube. Existing blood collection tubes are generally classified by the color of the caps. Existing blood collection tube caps are generally red, black, gray, purple, orange, green, etc. Each color of blood collection tube has its specific use and testing items.

[0003] The existing application number is: CN201410054665.0. The blood collection tube is composed of a sealing cover and a test tube, and the sealing cover is composed of a tube cover and a rubber plug. The tube cover and the rubber plug are formed by a two-color injection molding process. First, the tube cover is integrally injection molded, and then the rubber plug is injection molded and filled in the tube cover. The tube cover (1) is composed of a lower chamber (11) that matches the test tube, an upper chamber (14) that accommodates the rubber plug crown, a step (12), and a cylindrical opening (13) extending downward from the top of the upper chamber. The opening (13) and the top of the rubber plug together form a groove, which reduces the amount of rubber used and significantly reduces costs.

[0004] Based on the above, when the existing blood collection tubes are in use, when medical staff use the blood collection tubes at night, it is difficult for medical staff to distinguish the color of the blood collection tube caps because the medical staff's bodies block the light and the blood collection tubes are in a relatively dim environment, which makes it inconvenient to use. At the same time, after the blood collection is completed, the medical staff needs to shake the blood collection tube to mix the blood and the anticoagulant. When the blood in the blood collection tube is too full, the blood and anticoagulant in the blood collection tube have a small flow range, which affects the mixing efficiency of the blood and the anticoagulant.

[0041] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0042] Embodiment 1:

[0043] As attached Figure 1 To Attachment Figure 5 As shown:

[0044] The utility model provides a blood collection tube that is convenient to classify, comprising a first blood collection tube body 1, a second blood collection tube body 2, a blood collection tube cap 3, a blood collection connection hole 4, a sealing plug 5 and a blood collection auxiliary mechanism;

[0045] The second blood collection tube body 2 is interference-connected to the lower end of the first blood collection tube body 1;

[0046] The blood collection tube cap 3 is inserted into the upper end of the first blood collection tube body 1, and the outer periphery of the blood collection tube cap 3 is provided with an anti-slip pattern structure;

[0047] The blood sampling connection hole 4 is provided at the middle position of the upper end of the blood sampling tube cap 3;

[0048] The sealing plug 5 is fixedly connected to the inner upper end of the blood collection tube cap 3, and the sealing plug 5 is a disc-shaped rubber structure;

[0049] The blood sampling auxiliary mechanism is provided outside the second blood sampling tube body 2 .

[0050] The blood sampling auxiliary mechanism includes: a holding magnetic block 101, a first limit block 102, a second limit block 103 and a sealing ring 104;

[0051] The holding magnetic block 101 is a circular magnet structure, and the holding magnetic block 101 is fixedly connected to the outer periphery of the second blood collection tube body 2;

[0052] The first limit block 102 is a circular ring structure, and the first limit block 102 is fixedly connected to the inner upper end of the second blood collection tube body 2;

[0053] The second limit block 103 is a circular ring structure, and is fixedly connected to the lower end of the outer side of the first blood collection tube body 1. The second limit block 103 is arranged below the first limit block 102.

[0054] The sealing ring 104 is a circular rubber structure, and the sealing ring 104 is fixedly connected to the middle position of the outer side of the first blood sampling tube body 1 .

[0055] During use, when the medical staff needs to draw blood from the volunteer, the second blood collection tube body 2 is moved downward. The downward movement of the second blood collection tube body 2 drives the first limit block 102 to move downward. The first limit block 102 moves downward until it overlaps with the second limit block 103 and stops. At this time, the medical staff can draw blood from the volunteer. When the medical staff has completed the extraction of the blood sample in the blood collection tube, the medical staff moves the second blood collection tube body 2 upward. At this time, the first blood collection tube body 1 shrinks into the interior of the second blood collection tube body 2, reducing the occupied space of the entire blood collection tube and facilitating the subsequent disposal of medical waste. When the medical staff needs to hold multiple groups of blood collection tubes, the holding magnetic blocks 101 on the periphery of each group of second blood collection tube bodies 2 are magnetically connected to each other, which prevents the blood collection tube from falling off in the hands of the medical staff and facilitates the medical staff to hold the blood collection tube.

[0056] Embodiment 2:

The classification lamp 203 is electrically connected to the positive electrode of the button battery inside the classification lamp 203. The light color of the classification lamp 203 is consistent with the color of the blood collection tube cap 3. The classification lamp 203 is fixedly connected to the upper end of the first blood collection tube body 1.

[0066] During use, when the medical staff draws blood from the volunteer, the blood collection needle is inserted into the sealing plug 5, and the blood collection needle squeezes the mixing ball 202 downward. The mixing ball 202 is squeezed inside the mixing hose 201 and falls into the second blood collection tube body 2. At the same time, the mixing ball 202 moves downward to drive the classification trigger 205 to rotate. The rotation of the classification trigger 205 drives the classification trigger electrode 206 to rotate in the opposite direction. The classification trigger electrodes 206 rotate in the opposite direction and contact under the action of the classification squeezing spring 207. At this time, the circuit of the classification lamp 203 is connected and emits light. The medical staff can classify the blood collection tubes according to the light of the classification lamp 203, which is convenient for the medical staff to classify the blood collection tubes in a relatively dim environment.
