Description

[Detailed Description of the Invention] The present invention relates to a measuring centrifuge tube stand for accommodating centrifuge tubes with caps.

As centrifuge tubes with caps for measuring body fluids, there have been known products made of soft synthetic resin that are composed of a tube body and a cap provided with a connecting body that allows the cap to be opened and closed freely. These centrifuge tubes are opened by pushing up the protrusion provided at the end of the cap with your finger.If you are lining up the centrifuge tubes in a centrifuge tube stand, it will be easier to handle them if you point the protrusion in a certain direction. be. However, conventional centrifuge tube stands do not have an upper lid and do not have accommodation holes for fixing the cap connector, so the centrifuge tubes rotate and it is difficult to keep several centrifuge tubes in a fixed direction, and the caps cannot be opened or closed at the same time. It was inconvenient because I couldn't do it sometimes. In addition, after injecting the specimen into the centrifuge tube, the tube must be shaken one by one by hand in order to bring it into contact with the reagent, making the operation complicated.

The present invention solves these drawbacks.In a centrifuge tube stand consisting of a hexahedral container for accommodating centrifuge tubes with caps, an insertion hole for erecting the centrifuge tubes with caps is provided on the top surface of the container, and This centrifuge tube stand for measurement has a housing hole for fixing the cap connector of the centrifuge tube in the upper lid which can be opened and closed in the form of an upward extension.

Hereinafter, the present invention will be explained with reference to drawings showing preferred embodiments. FIG. 1 is a perspective view showing an example in which a centrifuge tube is partially inserted into a container 1 according to the present invention, and FIG. 2 is a side longitudinal cross-sectional view showing a state in which a centrifuge tube 2 is inserted into the container 1. The container 1 is preferably a horizontally elongated rectangular parallelepiped, and the front surface thereof may be sloped with a wide base (trapezoidal when viewed from the side), and the upper surface 3 is provided with several centrifuge tubes, preferably 5 to 6 centrifuge tubes, at predetermined intervals. Insertion hole 4 for 2
exists. Correspondingly, at the bottom 5 of the container,
Preferably, several bottom insertion holes 6 are provided for inserting the bottom of the centrifuge tube. For example, as shown in FIG. 2, the bottom portion having the insertion hole is raised with respect to the bottom surface of the container. However, for example, when a self-supporting centrifuge tube is used, the bottom insertion hole 6 is not necessary, and in that case, the bottom and the bottom surface may coincide.

A housing hole 8 for housing a cap connector 10 of a centrifuge tube is provided in the upper lid 7, which extends upward from the back of the container and is openable and closable. This accommodation hole 8
is located at a position corresponding to the centrifuge tube insertion hole 4, and serves to accommodate and fix the cap connector 10 that is bent and protrudes rearward when the cap 9 of the centrifuge tube 2 is closed.

The connecting portion 12 between the upper lid 7 and the container back surface 11 is located at approximately the same height as the upper surface of the cap 9 of the centrifuge tube 2 and is bendable. When the upper lid 7 is closed in this way, the centrifuge tube 2 is fixed vertically, and in this case, the cap connecting body 10 protruding rearward from the cap 9 of the centrifuge tube 2 is fixed in the accommodation hole 8. The directions of the centrifuge tubes 2 are all fixed, and all the cap protrusions for opening the caps face toward the front of the container 1. Providing a window 14 on the front part 13 of the centrifuge tube stand is convenient for identifying the centrifugation situation in the centrifuge tube.

The container 1 of the invention is made from materials such as paper, synthetic resin, sheet metal, etc., and can be assembled from a piece of cardboard, as is known from FIG.

The centrifuge tube stand of the present invention is extremely useful for accommodating centrifuge tubes used in immunological measurements.

When using the centrifuge tube stand of the present invention, since all the centrifuge tubes face forward as described above, the cap can be opened and closed quickly. For example, tablets, powders, etc. for adsorbing substances that cause non-specific reactions in immunological reactions are individually placed in these centrifuge tubes, a sample such as plasma is added thereto, and the top lid 7 of the container 1 is closed. By closing, the caps 9 of each centrifuge tube 2 fixed in the insertion hole 4 and the bottom insertion hole 6 can be closed at once. Furthermore, by shaking while holding the top lid 7 and the bottom with your fingers, the inside of each centrifuge tube can be closed. samples can be easily processed at once. In this state, the entire centrifuge can be loaded into a centrifuge for centrifugation, and if several centrifuge tube stands are placed in parallel and loaded into the centrifuge, processing efficiency can be further improved. do.
