Referring to fig. 1-4, a special built-in serum cup of inspection heparin tube, including heparin tube 1, cup 2 and

filter screen

3, 2 activity suits of cup are inside

heparin tube

1, 2 external diameters of cup and 1 internal diameter of heparin tube are the same, cup 2 is upper and lower both ends open-ended cavity body, 2 inside inner chambers 21 that form of cup, 2 open-tops of cup are for drawing mouthful 22, filter screen 3 is fixed to be installed in 2 bottom openings of cup, 3 central authorities of filter screen are fixed with and have

elastic rubber slab

31, 31 thickness of rubber slab is greater than 3 thickness of filter screen, 31 diameters of rubber slab are greater than the blood sampling syringe needle external diameter. This scheme is through setting up cup 2, through heparin tube 1 and serum cup integrated design, need not manually to number the serum cup, has reduced potential unexpected mistake risk by a wide margin, sets up simultaneously that filter screen 3 can effectually remove impurity in the serum, promotes the advantage of blood specimen test accuracy.

Further, cup 2 is for moulding the material hard and making, and cup 2 still includes clamp 4, and clamp 4 is formed by the outside roll-over in 2 lateral walls tops of cup, and 1 corresponding position of heparin tube is equipped with the clamp seat 11 of annular evagination, and clamp 4 and clamp seat 11 closely agree with.

Further, the inner cavity 21 is in a conical column shape with a small upper part and a big lower part, and the inner diameter of the extraction opening 22 is larger than the outer diameter of the blood collecting needle head. This scheme is the circular cone column through setting up inner chamber 21, can effectual promotion liquid level, when serum is less, also does benefit to and draws the needle and absorb.

Furthermore, the aperture of the filter screen 3 is 0.05-0.1mm, and the wall thickness of the bottom of the cup body 2 is 0.05-0.1 mm. According to the scheme, the aperture of the filter screen 3 and the wall thickness of the bottom of the cup body 2 are set to be 0.05-0.1mm, and the lower limit of the size of suspended foreign matters needing to be intercepted is 0.05-0.5mm according to the existing research, so that the filter screen 3 is favorable for intercepting foreign matters such as blood clots and fibrin yarns suspended in blood serum or blood plasma and enabling the blood plasma or the blood serum to pass through smoothly, the sample needle of a testing instrument is prevented from being blocked, a better filtering effect can be obtained, and good testing precision is guaranteed.

Further, the filter screen 3 is made of nylon cloth, plastic, gauze or non-woven fabric. This scheme is made for nylon cloth, plastics, gauze or non-woven fabrics through setting up filter screen 3, has effectively reduced manufacturing cost.

Furthermore, the annular bottom of the inner wall of the clamp seat 11 is an inclined plane 111 inclined from inside to outside, the clamp 4 comprises an elastic bending portion 41, a clamping portion 42 and a tight attaching surface 43, the clamping portion 42 is annular, the clamping portion 42 is connected with the top of the side wall of the cup body 2 through the elastic bending portion 41, the clamping portion 42 is tightly fitted in the clamp seat 11, and the bottom of the clamping portion 42 is tightly attached to the surface of the inclined plane 111 to form the smooth and tight attaching surface 43. According to the scheme, the clamp 4 and the clamp seat 11 are adopted, so that the cup body 2 can be tightly fixed in the blood collection tube 1, the blood collection needle is prevented from being inserted to cause the cup body 2 to move randomly, meanwhile, the elastic bending portion 41 and the clamping portion 42 are arranged to be matched with the structure formed by the clamp seat 11, and after blood collection is completed, the cup body 2 can move freely in the blood collection tube 1, so that subsequent centrifugal operation is facilitated, and a good filtering effect is obtained.

The utility model discloses when using:

when not in use, the clamp 4 is tightly fitted on the clamp seat 11, and the close-fitting surface 43 is tightly fitted on the inclined surface 111, so that the cup body 2 is tightly fitted in the blood collection tube 1.

When the blood sampling tube 1 communicates with the external blood sampling needle, the blood sampling needle sequentially penetrates through the sealing cover of the blood sampling tube 1 and the inner cavity 21 of the cup body 2, and pierces the rubber plate 31 to penetrate into the inside of the blood sampling tube 1 below the cup body 2, and the collected blood samples flow into the inside of the blood sampling tube 1 due to the vacuum effect and are stored at the lower part of the blood sampling tube 1. The blood sampling is accomplished, removes the blood taking needle, and the blood taking needle breaks away from in the rubber slab 31, because rubber slab 31 has elasticity, can self-sealing the perforation that the blood taking needle caused, keeps apart the blood sample in blood sampling 1 lower part.

It should be noted that, when the blood sampling needle is inserted, the clamp 4 is clamped on the clamp seat 11, so that the problem that the blood sampling needle cannot pierce the rubber plate 31 due to downward movement of the cup body 2 due to the inserted downward pressure is avoided; when taking out the blood sampling needle, because the frictional resistance of rubber slab 31, cup 2 can be along with blood sampling needle together rebound, clamp 4 breaks away from clamp seat 11, clamping part 42 is under the effect of elastic bending portion 41, the tight top lateral wall of cup 2 of clamp to make hug closely face 43 hug closely 2 top lateral walls, need slightly press cup 2 downwards again this moment, make elastic bending portion 41 take place elastic deformation, and make cup 2 slide in clamp 4 below, let cup 2 can be free slide from top to bottom in heparin tube 1.

And (3) putting the blood collection tube 1 after blood collection into a centrifuge for centrifugal separation, wherein the blood sample is gradually layered, the upper layer is light yellow serum, and the lower layer is solid substances such as dark red blood cells and the like. Because the cup 2 can be free slide from top to bottom in heparin tube 1, under the effect of centrifugal force, cup 2 can get rid of to heparin tube 1 bottom to the extrusion blood sample. Under the action of the extrusion force, the liquid pure serum passes through the filter screen 3 and enters the inner cavity 21, and foreign matters such as blood clots and fibrin threads in the serum, and solid substances such as blood cells and the like are blocked by the filter screen 3 and remain below the filter screen 3. After the centrifugation is stopped, the pure serum is substantially introduced into the inner cavity 21, and the pure serum is extracted by inserting the extraction needle into the extraction port 22.

In addition, the conical column shape of the inner cavity 21 can effectively improve the liquid level height, and is favorable for the suction of an extraction needle when the serum is less.

The filter screen 3 is used for intercepting foreign matters such as blood clots and fibrin threads suspended in blood serum or blood plasma and enabling the blood plasma or the blood serum to pass through smoothly so as to avoid blocking a sample needle of a testing instrument, and according to the existing research, the lower limit of the size of the suspended foreign matters needing to be intercepted is 0.05-0.5mm, preferably 0.05-0.1mm, so that the aperture of the filter screen 3 and the wall thickness of the top of the cup body 2 are set according to the lower limit, and a better filtering effect can be obtained.

The utility model discloses possessing heparin tube 1 and serum cup integrated design, having reduced latent unexpected mistake risk by a wide margin, and conveniently getting rid of impurity in the serum, effectively promoting the advantage of blood specimen test accuracy, solved artificial separation serum and leaded to latent mistake accident risk easily, impurity in the serum is got rid of to the manpower, the too loaded down with trivial details problem of operation.

The above description is only an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
