JPH03181852A - Method and container for collecting blood clot from test tube after separation of serum by centrifugal method from blood specimen collected using serum separating agent-containing test tube - Google Patents

Abstract

PURPOSE:To collect blood clot from which a serum separating agent is perfectly removed by covering a test tube having the serum separating agent already subjected to the separation of serum using a centrifugal method received therein with a serum collecting container and centrifugalizing the same in such a state that the container is turned downwardly. CONSTITUTION:A blood clot collecting container 2 is a tubular one closed at its one end having thickness enough to simply make a test tube ready to obtain blood clot 4 detachable. The opening part of the test tube ready to obtain blood clot 4 is covered with a blood clot collecting container 2 and the test tube is set to a centrifuge in such a state that the opening part of the blood clot collecting container 2 is turned downwardly to be subjected to centrifugation. When the centrifugation is performed by this method, since a separating agent 3 is lighter than the blood clot 4 in specific gravity, the separating agent 3 is above the blood clot 4 before the start of centrifugation but the blood clot 4 is positioned above the separating agent 3 after centrifugation. That is, the position of the blood clot part and that of the separating agent are reversed. When the covered blood clot collecting container 2 is detached, the separating agent remains in the original test tube having the separating agent received therein and the blood clot 4 enters the blood clot collecting container 2. By this method, the blood clot from which the separating agent is perfectly removed can be collected.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention involves placing a container over a test tube containing a separating agent that separates blood into serum and blood clots using the specific gravity after serum separation, and centrifuging it upside down. A blood clot collection method and container for collecting blood clots based on the difference in specific gravity between a separation agent and a blood clot.

[Prior Art] Conventionally, in order to obtain a blood clot from a test tube containing a serum separating agent for serum bone Mf&, the separating agent was scraped out with a stick, spatula, etc.

[Problems to be Solved by the Invention] When removing the separating agent using the conventional method, the test tube body, scraping rod, scraper, etc. become sticky and dirty with the separating agent, and it takes a lot of effort to remove the dirt. there were.

When scraping out the separating agent with a stick or spatula, it takes too much time to completely remove the separating agent, and it is actually impossible. Blood type tests, irregular antibody tests, etc. using blood tests were not possible.

Therefore, when it is better to collect blood in a test tube containing a separation agent, such as a biochemical test, it is not possible to conduct an accompanying test using blood cell components, and the sample is collected in a separate test tube without a separation agent. Blood had to be drawn again, which placed a heavy mental and physical burden on the patient and a heavy financial burden on the testing party.

The present invention aims to reduce the mental and physical burden on the patient and the economic burden on the testing side, and to help streamline testing techniques by re-centrifuging the test tube upside down with a blood clot collection container on top. The aim is to obtain a blood clot from which the separating agent has been completely removed.

[Means for solving the problem] In order to achieve the above purpose, the blood clot collection container is a tubular container with one end closed and having a length and thickness that allows the test tube from which the blood clot is to be obtained to be easily attached and removed. Make it. Place a blood clot collection container over the closed end of the test tube from which you wish to obtain a blood clot (Figure 1), place the blood clot collection container in a centrifuge with the closed end facing down, and centrifuge.

[Function] When centrifugation is performed as described above, the separation agent has a lower specific gravity than the blood clot, so before the centrifugation starts, the result is as shown in Figure 3, but after centrifugation, the result is as shown in Figure 4. In other words, the positions of the blood clot and separating agent are reversed. When the clot collection container that had been placed over the tube is removed, the separation agent remains in the original test tube containing the separation agent, and the clot enters the tL clot collection container.

[Example] To explain the example with reference to the drawings, as shown in Figure 1, it has the shape of a test tube, and is made of a material that does not break easily, such as transparent plastic. A blood clot collection container is placed over the opening of the test tube in which the blood clots are to be obtained, using a centrifuge for serum separation, using a medium-sized centrifuge.
Place the clot collection container in a centrifuge with the closed end facing down and centrifuge. The centrifugation conditions are the same as those used for serum separation (for example, 3000 r, p, m for 10 minutes).The blood clot is removed from the centrifuge, the blood clot collection container is removed, and the blood clot is used as necessary.

[Effects of the Invention] Since the present invention is configured as explained above, it has the following effects.

Separating agent no longer sticks to the test tube body, scraping rod, scraper, etc. and causes stains when removing the separating agent.

The separation agent can be completely removed in a short period of time, and blood type tests, irregularity antibody tests, etc. using blood cell components can be performed without any separation agent remaining.

Therefore, it is better to collect blood in a test tube containing a separating agent.It is possible to perform tests using blood cell components accompanying the specimen such as biochemical tests, and it is better to collect blood in a separate test tube that does not contain a separating agent. This reduces the mental and physical burden on the patient and the financial burden on the testing party.

In addition, as medical waste has become a problem, blood clots and
Removing IPI is an invaluable aid in waste disposal.
