[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sample transfer device for transferring a blood sample from a vacuum blood collection tube after blood collection to a test tube.

[0002]

2. Description of the Related Art The presence or absence of infection with various viruses,
Blood tests, which provide other useful information, occupy an extremely important position among various medical tests. Blood collection for this blood test is generally performed using a vacuum blood collection tube.

FIG. 2 is an explanatory diagram showing blood collection by a vacuum blood collection tube. A blood collection cap 1 having a substantially tray-like shape is used for this blood collection, and a blood collection needle 1a is provided above the center of the plate surface of the blood collection cap 1. Is projectingly arranged, and the introducing needle 1b is projectingly arranged below. The blood collection cap 1 is adapted to be fitted to the outside of the vacuum blood collection tube 3, and the vacuum blood collection tube 3
Is sealed in a state in which the inside is kept in a vacuum by a sealing lid 4 provided with a rubber insertion portion 4a in the central portion.
Further, in the vacuum blood collection tube 3, a separating agent having a specific gravity intermediate between serum and platelets is stored in advance.

Therefore, in order to collect blood from the subject 2,
First, as shown in FIG. 2 (a), the blood collection needle 1a of the blood collection cap 1 is inserted into the blood vessel of the subject 2, and in this state, the vacuum blood collection tube 3 is sealed with the sealing lid 4 as shown in FIG. 2 (b). Fit into the blood collection cap 1. By doing so, the insertion portion 4a of the vacuum blood collection tube 3 is penetrated by the introduction needle 1b, and the inside of the blood vessel and the inside of the vacuum blood collection tube 3 are connected,
Blood is collected in the vacuum blood collection tube 3 held in vacuum.

When the blood sample collected in the vacuum blood collection tube 3 is centrifuged by the centrifuge in this way, the serum 5 and the platelets 3 are separated by the separating agent 6 in the vacuum blood collection tube 3 as shown in FIG. To be separated. Therefore, when performing a blood test, the serum 5 separated from the platelets 7 is transferred to a test tube by a separating agent 6 as shown in FIG. 3, and various kinds of serum 5 collected in the test tube are subjected to various tests. The inspection is done.

In this case, when transferring the serum 5 from the vacuum blood collection tube 3 to the test tube, the sealing lid 4 of the vacuum blood collection tube 3 is removed and the serum 5 is poured into the test tube, or a syringe is inserted into the insertion portion 4a. This is done by penetrating the needle of No. 3 to suck the serum 5 into the syringe and discharging the sucked serum 5 to the test tube.

[0007]

When the serum 5 is transferred from the vacuum blood collection tube 3 to the test tube as in the conventional case, the sealing lid 4 of the vacuum blood collection tube 3 is removed and the serum 5 is poured into the test tube. The inspector wears gloves to keep the test tube in a stable state and makes every effort to prevent failure during injection. However, in this method, if the injection fails and the serum 5 may be scattered, a problem occurs in preventing infection. Further, in the method of transferring the serum 5 from the vacuum blood collection tube 3 to the test tube using a syringe, there is almost no risk of the serum 5 being scattered, but since the syringe is discarded each time, there is a problem in terms of test cost. Occurs.

The present invention has been made in view of the current state of the transfer of a blood sample from a vacuum blood collection tube to a test tube as described above, and an object thereof is to prevent the blood sample from scattering.
Another object of the present invention is to provide a sample transfer device that can safely and efficiently transfer a blood sample while reducing the number of discarded parts and reducing the inspection cost.

[0009]

In order to achieve the above object, a vacuum blood collection tube after blood collection is mounted on the upper surface side of a support,
The present invention, which is a sample transfer device in which a test tube is mounted on the lower surface side of the support and transfers the blood sample in the vacuum blood collection tube to the test tube, is provided on the upper surface side of the support, and A tube guide for guiding a blood vessel, a mounting surface on which a sealing lid of the vacuum blood collection tube guided by the tube guide is disposed, and a projecting upward from the mounting surface,
An introduction needle penetrating the airtight lid, a sealing means provided on the lower surface side of the support for sealingly disposing the inspection tube, and a pressure control means provided in the sealing means for controlling the pressure in the inspection tube. It is configured to have.

[0010]

According to this structure, the vacuum blood collection tube after blood collection is guided by the tube guide from the upper surface side of the support body and mounted with the sealing lid facing the mounting surface, and the test tube is mounted from the lower surface side of the support body. Are sealed by the sealing means. Thus, when the vacuum blood collection tube is attached, the introduction needle protruding upward from the mounting surface penetrates the sealing lid. Then, the pressure control means provided in the sealing means lowers the pressure in the test tube, whereby the blood sample is transferred from the vacuum blood collection tube into the test tube through the introduction needle, and after the transfer of the blood sample, the pressure control means is used. By increasing the pressure in the test tube, the test tube containing the blood sample is removed from the sealing means and a blood test is performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Here, FIG. 1 is an explanatory diagram including a cross-sectional portion showing the configuration of the present embodiment. As shown in the figure, in this embodiment, the support 10 on which the vacuum blood collection tube 3 after blood collection is mounted is provided with a mounting surface 10c having a substantially disc shape, and the peripheral edge of the mounting surface 10c. The tube guide 10a
Are formed. An introduction needle 11 protruding upward is fixed to the center of the mounting surface 10c.
A skirt 10b is formed so as to project on the back surface side of the mounting surface 10c so as to surround one position. Further, a ring-shaped sealing body 12 is detachably arranged on the outer side of the skirt 10b, and one end of a tube 13 is fixed to a part of the sealing body 12, and the other end of the tube 13 is fixed. A pressure controller 14 is connected to. Although not shown, the sealing body 12 is fixedly arranged on the test stand by a support frame, and the test tube 8 is attached to the sealing body 12.
Can be attached and detached freely.

Next, the operation of transferring the blood sample in the embodiment having such a configuration will be described. First, the test tube 8 to which the blood sample is transferred is fitted into the sealing body 12 arranged on the test table, and then the serum 5 and the platelet 7 which have already been described with reference to FIG. 3 are separated. The vacuum blood collection tube 3 containing the blood sample separated by the agent 6 is moved in the direction of the mounting surface 10c along the tube guide 10a with the sealing lid 4 facing the mounting surface 10c. By this movement, the introduction needle 11 penetrates the insertion portion 4, and the vacuum blood collection tube 3 is fitted and fixed to the support body 10 in a state where the insertion portion 4 is in contact with the mounting surface 10c.

In this state, when the pressure controller 14 is operated to reduce the pressure in the test tube 8, the vacuum blood collection tube 3
The serum 5 therein is transferred into the test tube 8 via the introduction needle 11. At the time when the transfer of the serum 5 in the vacuum blood collection tube 3 into the tester 8 is completed, the pressure controller 14 is operated to increase the pressure in the test tube 8 and return it to the atmospheric pressure.
The test tube 8 can be easily removed from the sealing body 12. At the time of this transfer, the serum 5 transferred from the introduction needle 11 into the test tube 8 is prevented from scattering to the sealing body 12 due to the presence of the skirt 10b. In this way, the serum 5 is collected from the test tube 8 containing the serum 5 transferred from the vacuum blood collection tube 3, and various blood tests are performed. At this time, the vacuum blood collection tube 3 and the support 10 that have been transferred are discarded.

As described above, according to the embodiment, the vacuum blood collection tube 3 containing the blood sample is easily attached, and the inspector simply controls the pressure of the pressure controller 14 so that the vacuum blood collection can be performed in a completely non-contaminated state. The blood sample in the blood vessel 3 can be safely transferred into the test tube 8. Only the vacuum blood collection tube 3 and the support body 10 are discarded after the transfer is completed, and there is no need to discard the syringe or the like, and it is possible to reduce the inspection cost.

In this embodiment, the case where one support is used has been described, but in reality, a large number of supports are arranged on the test stand and at the same time, blood samples from a plurality of vacuum sampling tubes are collected. It is possible to perform the transfer at the same time and to perform the efficient transfer operation.

[0016]

According to the present invention, the vacuum blood collection tube after blood collection is mounted from the upper surface side of the support body to the mounting surface with the sealing lid facing, and the test tube from the lower surface side of the support body by the sealing means. A vacuum blood collection tube in which the introduction needle, which is hermetically arranged and projects upward from the mounting surface, penetrates the sealing lid of the vacuum blood collection tube and reduces the pressure in the test tube by the pressure control means provided in the sealing means. Since the blood sample of the above is transferred into the test tube through the introduction needle, the blood sample in the vacuum blood collection tube can be safely transferred to the test tube in a completely non-contaminated state, and the discarded parts after the transfer is reduced. It is also possible to reduce the inspection cost.
