2. A blood collection tube holder as claimed in claim 1, wherein a ring groove (9) adapted to the blood collection tube cover is further provided around the test tube slot.

3. A blood collection tube mould frame as claimed in claim 1, wherein a limit screw cap (4) is further provided at one end of the support column (4) located at the support (3).

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a blood collection tube mould frame.

Background

The blood sampling pipe is in process of production with the blood sampling block directly place on the test tube mouth of pipe, get into the test tube again and take out the negative pressure, if the block cooperates improperly with the test tube mouth, can lead to this test tube to take out the negative pressure difficulty, the result is that the blood sampling pipe does not have negative pressure or the negative pressure is low on the side, if the test tube does not have negative pressure or the negative pressure is low on the side leads to in the clinical use can not accomplish the negative pressure blood sampling.

Disclosure of Invention

In order to solve the technical problem, the invention provides a blood collection tube mold frame, which is characterized by comprising: the fixed base is provided with a support column;

the support, be provided with a plurality of test tube slotted holes and a plurality of support column hole on the support, the support column runs through the support column hole, the support column outside still is provided with coaxial spring, the spring setting is in the support with between the unable adjustment base.

Furthermore, a ring groove matched with the blood sampling tube cover is arranged around the test tube slot hole.

Furthermore, one end of the support column, which is positioned on the support, is also provided with a limiting threaded cap.

Compared with the prior art, the special die set for the blood collection tube can solve the problem of unbalanced negative pressure pumping caused by the fact that the blood collection tube cap is directly placed on a test tube in the production process of the blood collection tube. It changes ordinary die carrier structure, increases spring assembly, makes the heparin tube block place on the die carrier upper plate, not with the test tube contact, remains the determining deviation between test tube and the block, when taking out the negative pressure and accomplish the back, pushes down block and top board, and top board compression spring accomplishes the block.

Detailed Description

The invention will be further explained with reference to the drawings.

Referring to fig. 1-3, a heparin tube mould frame is characterized by comprising: the fixed base 7 is arranged on the support column 5 on the fixed base 7;

support 3, be provided with a plurality of test tube slotted holes 8 and a plurality of support column hole on the support 3, support column 4 runs through the support column hole, the support column 4 outside still is provided with coaxial spring 5, spring 5 sets up support 3 with between the unable adjustment base 7.

And a ring groove 9 matched with the blood sampling tube cover is also arranged around the test tube slot hole.

The support column 4 is positioned at one end of the support 3 and is also provided with a limiting threaded cap 4.

When the test tube assembling device works, the cap 1 is placed on the ring groove 9, negative pressure is pumped when the test tube enters a negative pressure pumping box, when the negative pressure reaches a specified value, the cap 1 and the support 3 are pressed downwards, the support 3 compresses the spring 5, and the cap 1 is matched with the test tube 2 to complete assembling; the device can ensure the balance of the negative pressure value of each test tube when the negative pressure is pumped, and solve the problem that the individual blood sampling tube has no negative pressure or has low negative pressure.

Compared with the prior art, the special die set for the blood collection tube can solve the problem of unbalanced negative pressure pumping caused by the fact that the blood collection tube cap is directly placed on a test tube in the production process of the blood collection tube. It changes ordinary die carrier structure, increases spring assembly, makes the heparin tube block place on the die carrier upper plate, not with the test tube contact, remains the determining deviation between test tube and the block, when taking out the negative pressure and accomplish the back, pushes down block and top board, and top board compression spring accomplishes the block.

The above embodiments are merely illustrative of the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and implement the invention, and not to limit the scope of the invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the scope of the present invention.
