Description

Technical Field

[0001] The utility model relates to the technical field of blood centrifuge equipment, in particular to a blood centrifuge equipment. Background Art

[0002] In medical testing, centrifuges are often used as instruments to separate serum, plasma, precipitate proteins, or examine urine sediment. Centrifuges can be used to quickly precipitate the mixed liquid in a test tube, thereby separating the components of various substances with different specific gravities to achieve the purpose of concentration or separation from other particles.

[0003] Currently, when performing a centrifugation experiment on blood, the blood is first drawn from the patient's body into a test tube, and then multiple test tubes are placed in the centrifugal tank of a blood centrifuge. The high-speed rotation of the rotor in the blood centrifuge can provide a large centrifugal force to the blood in the test tube, thereby separating the serum and blood cells in the blood. However, different types of test tubes are used in different laboratory departments in hospitals, and different test tube types have different diameters and lengths. Generally, the diameter of a test tube is between 10mm and 13mm, and the length is between 50mm and 100mm. The depth of the centrifugal tank in existing centrifuge equipment cannot be changed, which makes it difficult to separate blood cells with longer lengths. After the liquid test tube is placed in the centrifuge tank, the distance between the top of the blood test tube and the open end of the centrifuge tank is relatively long, which makes the blood test tube easily thrown out of the centrifuge tank during high-speed rotation. After the blood test tube whose length is less than the opening depth of the centrifuge tank is placed in the centrifuge tank, the blood test tube enters the centrifuge tank as a whole under the action of gravity until the top of the blood test tube completely enters the centrifuge tank. When taking the blood test tube out of the centrifuge tank, it is not appropriate to directly clamp the outer wall of the blood test tube with fingers and pull it out of the centrifuge tank, which increases the cumbersomeness of taking out the smaller blood test tube from the centrifuge tank and reduces the practicality of the centrifuge equipment.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-5 The present invention provides an embodiment of a blood centrifuge device, comprising:

[0032] The blood centrifuge body 1 and the rotor have multiple connecting frames 2 fixedly installed on the outer wall of the rotor in an annular distribution, wherein multiple support blocks 4 are fixedly installed between two adjacent connecting frames 2, and multiple adapting holes 7 for adapting to test tubes are opened on the top of the support blocks 4. The multiple support blocks 4 are distributed in an annular shape under the action of the multiple connecting frames 2. When the centrifugal force test of the blood needs to be performed, the blood test tube is placed inside the adapting hole 7. When the rotor rotates rapidly, the multiple support blocks 4 rotate rapidly with the rotor, so that the blood test tube placed inside the adapting hole 7 is subjected to a strong centrifugal force, thereby separating the serum and blood cells (this is a prior art and will not be described in detail here).

[0033] Multiple limiting plates 3 are slidably installed just above the multiple supporting blocks 4, and multiple through holes are opened on the tops of the multiple limiting plates 3. The middle of the open ends of the multiple through holes and the middle of the open ends of the multiple adapting holes 7 are on the same horizontal line. The blood test tube is placed inside the adapting hole 7. First, the bottom of the blood test tube is inserted into the through hole. The bottom of the blood test tube passes through the through hole and enters the interior of the adapting hole 7 until the bottom of the blood test tube and the bottom of the inner cavity of the adapting hole 7 are fitted together.

[0034] The diameter of the adapting hole 7 is the same as that of the through hole. The diameters of the through hole and the adapting hole 7 are both greater than 13 mm, so that blood test tubes of different diameters can pass through the through hole and be inserted into the interior of the adapting hole 7. The opening depth of the adapting hole 7 is much less than 50 mm, so that the bottom of a blood test tube with a length of less than 50 mm can fit with the bottom of the inner cavity of the adapting hole 7, and the top of the blood test tube can be located directly above the limiting plate 3.

[0035] An adjusting member for adjusting the position of the limit plate 3 is provided on the outside of the support block 4. By adjusting the height of the limit plate 3 through the adjusting member, the distance between the limit plate 3 and the support block 4 can be adjusted, and the adjusted limit plate 3 can be positioned.

[0036] Insert the bottom of the blood test tube into the adapter hole 7 until the bottom of the blood test tube and the bottom of the inner cavity of the adapter hole 7 are fitted together, then push the limit plate 3 to move it away from the support block 4 until the distance between the top of the limit plate 3 and the top of the blood test tube is not less than 10 mm, and then fix the moved limit plate 3 through the adjustment piece, so that the blood test tube can be limited by the through hole and the adapter hole 7 to prevent the blood test tube from being thrown out from the inside of the adapter hole 7 when the support block 4 rotates at high speed. When taking the blood test tube out of the adapter hole 7, pinch the outer wall of the blood test tube at the top of the limit plate 3 with your fingers, and then pull the blood test tube out of the adapter hole 7, which reduces the cumbersomeness of taking out smaller blood test tubes from the inside of the adapter hole 7 and increases the practicality of the blood centrifuge body 1.

[0037] According to the above embodiment, when the blood test tube rotates rapidly with the rotor as the center, the huge centrifugal force generated is offset in the direction away from the rotor, so that the outer wall of the blood test tube fits with the through hole and the inner wall of the adapter hole 7, resulting in the outer wall of the blood test tube being subjected to a large extrusion force, which easily causes the outer wall of the blood test tube to be deformed and damaged. Therefore, in a further embodiment, a plurality of bellows 6 are further provided, one end of which is fixedly connected to the bottom of the limit plate 3, and the other end of the plurality of bellows 6 is fixedly connected to the top of the support block 4. The plurality of bellows The inner cavity of the tube 6 and the inner cavity of the adapting hole 7 and the through hole are connected to each other. When the bottom of the blood test tube is inserted into the through hole, it enters the interior of the bellows 6 and penetrates the bellows 6 and is inserted into the inner cavity of the adapting hole 7 until the bottom of the blood test tube and the bottom of the inner cavity of the adapting hole 7 fit together. At this time, the inner wall of the bellows 6 and the outer wall of the blood test tube fit tightly. When the blood test tube is subjected to a large centrifugal force, the bellows 6 prevents the blood test tube from deviating and fitting the adapting hole 7 and the inner wall of the through hole, thereby avoiding deformation and damage of the blood test tube.

[0038] The inner diameter of the bellows 6 is 10 mm, which enables the inner wall of the bellows 6 to fit tightly with the outer walls of blood test tubes of different sizes, thereby adapting to blood test tubes of different diameters.

[0039] The bellows 6 is made of rubber material, which allows the bellows 6 to have plastic deformation ability, so that a blood test tube with a diameter greater than 10 mm can be inserted into the bellows 6, while the inner wall of the bellows 6 is close to the outer wall of the blood test tube. It can also improve the flexibility of the bellows 6 and prevent the bellows 6 from squeezing the outer wall of the blood test tube and causing damage to the blood test tube.

[0040] When the limiting plate 3 moves up and down, the top of the bellows 6 moves together with the limiting plate 3 , thereby controlling the distance between the two ends of the bellows 6 .

[0041] The adjusting part includes a guide plate 5 and a slider 10. The guide plates 5 are symmetrically installed on both sides of the top of the support block 4. The limit plate 3 is located between the two guide plates 5. The adjacent sides of the two guide plates 5 are provided with guide grooves in the vertical direction. The slider 10 is slidably installed in the inner cavity of the guide groove, and one side of the slider 10 is fixedly connected to one side of the limit plate 3. Push or press the two sliders 10 at the same time to allow the two sliders 10 to move in the vertical direction through the guide groove, thereby controlling the distance between the limit plate 3 and the support block 4.

[0042] A guide rod 8 is fixedly installed in the inner cavity of the guide groove along the vertical direction, and the slider 10 is slidably sleeved on the outside of the guide rod 8. A guide hole is opened on the top of the slider 10, and the slider 10 is slidably sleeved on the outside of the guide rod 8 through the guide hole, thereby limiting the sliding trajectory of the slider 10 and preventing the slider 10 from falling off inside the guide groove.

[0043] The guide plate 5 is provided with a horizontal plate 12 on the side away from the limit plate 3 for sliding installation. The side of the horizontal plate 12 close to the guide groove extends into the inner cavity of the guide groove and is fixedly connected to the outer wall of the slider 10. A mounting hole is symmetrically opened on one side of the horizontal plate 12, and a limiting bolt 13 is detachably installed in the inner cavity of the mounting hole. A threaded hole 9 is opened in the vertical direction on the side of the guide plate 5 away from the limit plate 3, and the guide groove is located between the two mounting holes. When the limiting plate 3 is slid, the position of the limiting plate 3 is fine-tuned so that the middle of the open ends of the two mounting holes and the middle of the open end of the threaded hole 9 closest to itself are in the same horizontal line, and then the lower head end of the limiting bolt 13 is passed through the mounting hole and inserted into the inside of the threaded hole 9, and then the big head end of the limiting bolt 13 is continuously rotated until the big head end of the limiting bolt 13 is tightly fitted with the outer wall of the horizontal plate 12 to achieve the fixation of the horizontal plate 12.

[0044] A finger pressure plate 11 for its own movement is fixedly installed on the side of the horizontal plate 12 away from the slider 10. When the limit plate 3 moves up, press the top of the guide plate 5 with your thumb, fit the index finger and the bottom of the finger pressure plate 11, and move the index finger toward the thumb to achieve the upward movement of the limit plate 3. When the limit plate 3 needs to be moved down, press the two finger pressure plates 11 at the same time with your thumb to achieve the downward movement of the limit plate 3.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
