2. Description of the Related Art A conventional blood sedimentation tube has both ends opened and a length of 3 mm.
It is made of a glass tube of 0 cm and 3 mm inside diameter.
This glass tube is 1 m over 20 cm from the opening at one end.
A scale is attached every m. In the case of using such a conventional blood sedimentation tube, first, a blood anticoagulant, for example, 3.8% sodium citrate added to blood, is sucked with a human mouth to reduce the pressure in the blood sedimentation tube to reduce the blood. Was inhaled to point 0 (base point) of the sedimentation tube, or blood was inhaled to point 0 of the sedimentation tube using a syringe or the like. Further, the blood sedimentation tube was allowed to stand vertically, and the sedimentation state of red blood cells was measured every hour. At the end of the blood sedimentation test, the used blood sedimentation tube was washed, sterilized, dried and the like, and the used blood sedimentation tube was recycled.

[0003] However, in order to perform a blood sedimentation test using such a conventional blood sedimentation tube, it is necessary for a person to suck blood directly by mouth or to use a syringe to inject blood to the zero point of the blood sedimentation tube.
This operation is simple but requires skill and it takes time for manual work, so that it is difficult and impossible to process a large number of samples in a short time. In the course of examination work and in the course of cleaning, sterilization, drying, etc. by reusing, there is a possibility that healthcare workers may be infected with blood-borne diseases, for example, hospital-acquired infections such as viral hepatitis and AIDS. The accompanying work was also troublesome. Furthermore, if the conventional blood sedimentation tube has been used for a long period of time, fats and proteins adhere to the wall surface, so that the washing becomes incomplete and accurate data cannot be obtained.

In order to solve these problems, a blood sedimentation tube disclosed in Japanese Utility Model Publication No. 7-9092 has recently been developed. As shown in FIG. 6, the blood sedimentation tube 21 is made of a synthetic resin tube 22 of polyethylene, polystyrene, polypropylene, or the like, has a uniform inner diameter, and is open at both ends. A liquid inlet 23 is formed at the lower end of the synthetic resin tube 22, while a tapered opening 24 is formed at the upper end opening. The tapered opening 24 is configured so that the porous synthetic resin body 25 can be easily inserted into a predetermined position in the synthetic resin tube 22. The blood sedimentation tube 21 thus configured has a porous resin body (containing a superabsorbent polymer) that allows gas to pass therethrough but does not allow liquid to pass through a synthetic resin tube having a uniform inner diameter and open at both ends. Since it is inserted, insert the liquid inlet side of the sedimentation tube into the blood collected at the time of use, and depressurize the blood sedimentation tube from the other end of the sedimentation tube, so that the blood is immediately transferred to the insertion position of the porous synthetic resin body. Many were able to be introduced at the same time, but on the other hand, if the porous synthetic resin body dipped even a small amount of water droplets or blood at the time of use due to water penetration, the air permeability would be instantaneous. In addition, there is a problem that the blood sedimentation tube itself cannot be used.

[0005] Further, since the porous synthetic resin body is water-immersed, the blood cannot be stopped unless the pore diameter of the porous synthetic resin body is small and long. Therefore, it is necessary to increase the suction pressure in the blood sedimentation tube. When a superabsorbent polymer such as cornstarch in xerogel state comes into contact, not only cornstarch in xerogel state on the surface of the porous synthetic resin body becomes a normal gel, but this gel flows out into the blood sedimentation tube and red blood cells It will affect sedimentation.

The porous synthetic resin body 5 is a porous body obtained by subjecting a thermoplastic resin powder such as polyethylene, polypropylene, ethylene vinyl acetate copolymer, polystyrene, acrylonitrile copolymer or the like to semi-melt molding. It is obtained by adhering a superabsorbent polymer (xerogel) to the surface. This semi-solid molding means that the powder layer of the thermoplastic resin as described above is filled in a mold having a predetermined shape, the filling layer is pressed for the purpose of adjusting the porosity, and the powder particle layer is uniformly formed. This is a molding method in which the particles are cooled when the contact surfaces of the particles are fused in a semi-molten state, and furthermore, the voids between the particles form a completely continuous three-dimensional space (pores). The hydrophilic polymer refers to a polymer compound having a water absorbing ability and a sealing ability, such as gelatin, agar, and gum arabic, and the xerogel refers to a state in which the superabsorbent polymer is in a dry state.

As described above, the porous synthetic resin body 5 is obtained by adhering a highly water-absorbing polymer in a xerogel state to a porous body obtained by half-molding the above-mentioned thermoplastic resin powder. Therefore, when a gas such as air passes, but a liquid such as blood comes into contact with the porous synthetic resin body 5, the superabsorbent polymer in a xerogel state instantly absorbs the liquid and a xerogel-like superabsorbent polymer. Swells so that liquid cannot pass through. Note that the porous synthetic resin body 5 has a scale of 20 cm in which one end face thereof is attached in increments of 1 mm from the liquid inlet 3 side.
Is inserted into the space 2 between the synthetic resins so as to be located at the zero point (base point).
