Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a blood leukocyte concentration pipe. BACKGROUND

[0002] In blood sample examination, the reasons for leukopenia include drug side effects, certain drugs, anti-thyroid drugs, certain antibiotics and anti-psychotic drugs, which can cause leukopenia; infection, certain viral infections, such as influenza, viral hepatitis, etc., which can cause a decrease in the number of leukocytes; blood system diseases, such as aplastic anemia, myelodysplastic syndrome, etc., which directly affect the hematopoietic function of bone marrow, leading to a decrease in leukocyte production; autoimmune diseases, such as systemic lupus erythematosus, etc., which can produce antibodies against their own cells in the patient's body, and these antibodies can attack and destroy leukocytes; malignant tumors: during the treatment process, such as radiotherapy and chemotherapy, which can inhibit the hematopoietic function of bone marrow, leading to leukopenia.

[0003] In blood examination, the following cases require leukocyte concentration: 1. Samples that require leukocyte morphology observation for clinical staining, some samples have few leukocytes due to various reasons, and the number of leukocytes that can be observed by conventional film making is limited, which can easily miss abnormal cells; 2. Special items require leukocyte concentration detection, such as lupus erythematosus cell examination.

[0004] However, the commonly used leukocyte concentration method is to directly centrifuge the blood tube, discard the plasma layer, and take the leukocyte layer for film making. This method has poor leukocyte acquisition effect due to the large area and thin thickness of the leukocyte layer. UTILITY MODEL CONTENTS

[0005] In order to solve the above technical problems, the utility model designs a blood leukocyte concentration pipe to facilitate the concentration and acquisition of leukocytes.

[0006] The blood leukocyte concentration pipe of the utility model has the advantages that the outer pipe body is a transparent cylindrical pipe, the inner pipe body is installed in the outer pipe body, the rubber pad is arranged between the bottom of the inner pipe body and the outer pipe body to support the inner pipe body, the upper part of the inner pipe body is a funnel-shaped pipe body, the funnel-shaped pipe body and the long columnar transparent pipe body below the neck part of the funnel-shaped pipe body have a volume ratio of 2:3, and the leukocyte layer is concentrated in the funnel-shaped pipe body.

[0007] An observation window is further formed in the outer pipe body.

[0008] The pipe cover is made of elastic soft rubber, and the surface has anti-slip stripes.

[0009] The utility model has the advantages that the leukocyte layer is concentrated in the funnel-shaped pipe body, the leukocyte layer is thick and the area is small, the leukocyte acquisition effect is good, the leukocyte concentration pipe is convenient to use, and the leukocyte concentration pipe can be used for leukocyte concentration and acquisition.

[0010] When the blood examination white blood cell concentration is carried out, the shape design of the inner tube body is wide at the top and narrow at the bottom, the wide-mouthed funnel design can effectively utilize the space, and the dropper is convenient to extend into the cell for sucking, the lower narrow long cylinder, and the design of the volume ratio of the upper and lower two sections 2:3 can ensure that the white blood cell layer falls below the position of the funnel neck after centrifugation, which can effectively reduce the area of the white blood cell layer and increase the thickness of the white blood cell layer, and the wide-mouthed funnel design is convenient for the common medical dropper to extend into the white blood cell layer for sucking, the device is simple to operate, and the concentrated white blood cells can be easily and effectively obtained.

[0020] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0021] Embodiment 1

[0022] In order to facilitate the concentration of white blood cells in blood examination, refer to Figures 1 to 4As shown, the blood leukocyte concentration tube in the embodiment comprises an outer tube body 2, which is a transparent cylindrical tube. The outer tube body 2 is connected with a tube cover 1 at the top. The tube cover 1 is made of elastic soft rubber and has anti-skid stripes 11 on the surface. An inner tube body 3 is installed in the outer tube body 2. The outer tube body 2 and the inner tube body 3 are made of PET plastic or medical borosilicate glass. A rubber pad 4 is arranged between the bottom of the inner tube body 3 and the outer tube body 2 to fill and support, so as to prevent the inner tube body 3 from directly contacting and rubbing with the outer tube body 2 during centrifugation, thereby preventing the tube body from being broken. The upper part of the inner tube body 3 is provided with a funnel-shaped tube body 31. Below the neck of the funnel-shaped tube body 31 is a long columnar transparent tube body 32. The caliber of the long columnar transparent tube body 32 is 0.5 cm. The volume ratio of the funnel-shaped tube body 31 to the long columnar transparent tube body 32 is 2:3, which can effectively reduce the area of the leukocyte layer 6 and increase the thickness of the leukocyte layer 6, so as to ensure that the leukocyte layer 6 falls below the position of the neck of the funnel after centrifugation, and facilitate the common medical dropper to be inserted into the leukocyte layer 6 to suck the leukocyte layer 6.

[0023] When the blood leukocyte concentration is performed, the blood is sucked into the inner tube body 3, the tube cover 1 is covered, and the blood leukocyte concentration tube is placed into a centrifuge for centrifugation. The blood amount is controlled to be below the warning scale line 22 to prevent the blood from spilling out of the tube. Figure 5 And Figure 6 As shown, the blood plasma layer 5, the leukocyte layer 6 and the red blood cell layer 7 of the blood are distinct. For the blood sample after centrifugation, the disposable dropper can be directly used to remove the blood plasma layer 5 and then suck the leukocyte layer 6, so as to effectively and accurately obtain the concentrated leukocyte, and the operation is simple and easy to implement.

[0024] In order to better observe the effect of the blood after centrifugation and facilitate the sucking of the leukocyte layer 6, the outer tube body 2 is further provided with an observation window 21.

[0025] The preferred embodiments disclosed above are only used to help describe the utility model. The preferred embodiments do not describe all the details and limit the utility model to the specific embodiments. Apparently, according to the content of the specification, many modifications and changes can be made.
