Problems solved by technology

[0003] The existing vacuum blood collection tube centrifuges have large vibration and high noise during operation, and the speed and centrifugal force are limited to a certain extent. At the same time, the number and placement direction of the blood collection tubes are also limited. It is required that the vacuum blood collection tubes must be placed symmetrically in an even number Can refer to a kind of vacuum blood collection tube automatic decap centrifuge of publication number C7201410415Y at the same time, its radial outer end is free to hang in the air when its rotating blue frame rotates, when the vacuum blood collection tube quantity that there is placed on each hanging basket is different, also can be in When working, the vibration is large, the noise is high, and the speed and centrifugal force are limited to a certain extent.

Embodiment 1

[0045] Embodiment one: see Figure 1-12 , a vacuum blood collection tube centrifuge, including a casing 1, a centrifugal motor 2 and a rotating blue frame 3.

[0046] The output end of the centrifugal motor 2 is connected with the rotating frame 3 and is used to drive the rotating frame 3 to rotate; the rotating frame 3 is provided with four hanging baskets 7 .

[0047] see Figure 1-4 , The casing 1 is provided with a centrifuge cylinder, the centrifuge cylinder has a centrifuge chamber 1-1 inside, and the rotating basket 3 is located in the centrifuge chamber 1-1.

[0048] see Figure 5-6 , four radial struts 3-1 are fixed on the rotating frame 3, and the outer end of each radial strut 3-1 is connected with the inner wall of the centrifuge chamber 1-1 by a kinematic pair.

[0049] In the present invention, since the outer ends of a plurality of radial struts 3-1 on the rotating frame 3 are connected to the inner wall of the centrifuge chamber 1-1, the rotating frame 3 is ...

Embodiment 2

[0069] Embodiment 2: This embodiment is basically the same as Example 1, the difference lies in the specific structure of the connection between the outer end of each radial strut 3-1 and the inner wall of the centrifugal chamber 1-1.

[0070] In this example, see Figure 13-14 , the inner wall of the centrifugal chamber 1-1 is fixedly provided with a bearing outer ring 6-1, and the outer end of each radial strut 3-1 is fixedly connected to the bearing inner ring 6-2, and the bearing outer ring 6-1 is connected to the bearing The inner rings 6-2 are connected by rollers 6-3. Since the bearing outer ring 6-1 and the bearing inner ring 6-2 are connected by the roller 6-3, when the bearing outer ring 6-1 and the bearing inner ring 6-2 rotate with each other, the motion process can be reduced. The friction coefficient in the middle, and at the same time ensure its rotation accuracy, it has the advantages of high precision, good rigidity, fatigue resistance, high speed and so on. ...

Abstract

The invention discloses a vacuum blood collection tube centrifuge. The vacuum blood collection tube centrifuge comprises a casing (1), a centrifugal motor (2) and a rotary basket rack (3); the outputend of the centrifugal motor (2) is connected with the rotary basket rack (3) and used for driving the rotary basket rack (3) to rotate; and a plurality of hanging baskets (7) are arranged on the rotary basket rack (3). The vacuum blood collection tube centrifuge is characterized in that a centrifugal chamber (1-1) is arranged in the casing (1); the rotary basket rack (3) is positioned in the centrifugal chamber (1-1); a plurality of radial support rods (3-1) are fixedly arranged on the rotary basket rack (3); and the outer ends of the radial support rods (3-1) are in kinematic pair connectionwith the inner wall of the centrifugal chamber (1-1). The vacuum blood collection tube centrifuge has small vibration and low noise during working and is more suitable for working conditions of highrotating speed and high centrifugal force, and severe limitation to the number and positions of vacuum blood collection tubes is avoided.

Description

technical field [0001] The invention belongs to a centrifuge for vacuum blood collection tubes. Background technique [0002] Medical centrifuges generally refer to vacuum blood collection tube centrifuges in hospital laboratories, blood stations, blood banks, physical examination centers, etc. [0003] The existing vacuum blood collection tube centrifuges have large vibration and high noise during operation, and the speed and centrifugal force are limited to a certain extent. At the same time, the number and placement direction of the blood collection tubes are also limited. It is required that the vacuum blood collection tubes must be placed symmetrically in an even number Can refer to a kind of vacuum blood collection tube automatic decap centrifuge of publication number C7201410415Y at the same time, its radial outer end is free to hang in the air when its rotating blue frame rotates, when the vacuum blood collection tube quantity that there is placed on each hanging bas...
