Label printing and pasting means 20 disposed above the blood collection tube containing means 2;
And a first transfer means 30 for transferring a blood collection tube selectively taken out from the blood collection tube storage means 2 to the label printing sticking means 20.

Each blood collection tube storage means 2 includes four blood collection tube storage cases 3 that can be taken in and out of the housing 80. The blood collection tube storage case 3 is stored in the housing 80 so that the first transfer means 30 side is inclined downward. The
6 is a perspective view of the blood collection tube storage case 3 as viewed obliquely from above, FIG. 7A is a perspective view of the blood collection tube storage case 3 as viewed from obliquely below, and FIG. 8A is a longitudinal sectional view of a part of the blood collection tube housing case 3, FIG. 8B is a sectional view taken along the line AA in FIG. 8A, and FIG. The side view which shows the state which accommodated the blood vessel storage case 3 in the housing 80, FIG. 10 is the perspective view which looked at the accommodation state of the blood collection tube storage case 3 shown in FIG. 9 from diagonally downward, FIG. 12 is a schematic top view of the substrate 7 showing the relationship between the blood collection tube housing case 3 and a substrate 7 described later.
As shown in FIGS. 6 and 8, a remaining amount detection slide plate 4 is provided inside the blood collection tube storage case 3.
The remaining amount detection slide plate 4 includes a base portion 4a extending along the bottom surface of the blood collection tube storage case 3, and a partition plate portion 4b that rises vertically from the front end of the base portion 4a and partitions the inside of the blood collection tube storage case 3 in the front-rear direction. And an L-shaped main body. An inverted T-shaped guide member 4c is fixed to the base portion 4a with an appropriate fixing member such as a bolt. A magnet 4d extending in the longitudinal direction of the blood collection tube housing case 3 is fixed to the bottom of the guide member 4c.
In the remaining amount detecting slide plate 4 configured as described above, the narrow portion of the inverted T-shaped guide member 4c is inserted into the longitudinally extending guide slit 3a provided on the bottom surface of the blood collection tube housing case 3. By fitting, it is attached to the blood collection tube housing case 3 so as to be movable in the longitudinal direction.
9-12, the board | substrate 7 is provided in the position corresponding to the front part of the blood-collecting-tube accommodation case 3 in the housing 80, and the slide for residual amount detection is provided in the center of the width direction of this board | substrate 7. As shown in FIG. A plurality of magnetic sensors 7a for detecting the position of the magnet 4c provided on the plate 4 are provided in a row.
9 to 11, a case vibration mechanism 8 for vibrating the blood collection tube storage case 3 is provided at a position corresponding to the rear portion of the blood collection tube storage case 3 in the housing 80. The case vibration mechanism 8 includes a motor 8a and an elliptical cam 8b. The motor 8a is driven by the control device 70 as necessary to rotate the cam 8b. Thereby, the cam 8b vibrates the rear part of the blood collection tube storage case 3 up and down.
With the configuration described above, the remaining amount detection slide plate 4 can freely move in the front-rear direction inside the blood collection tube housing case 3 along the guide slit 3a. The remaining amount detection slide plate 4 is stopped by the blood collection tube when the blood collection tube is housed in the blood collection tube housing case 3. However, as described above, the blood collection tube housing case 3 is housed in the housing 80 so that the first transfer means 30 side is lowered, and the rear portion of the blood collection tube housing case 3 is required by the case vibration mechanism 8. It can be vibrated up and down according to. For this reason, when the number of blood collection tubes in the blood collection tube storage case 3 decreases as a result of use, the remaining amount detection slide plate 4 causes the vibration by the case vibration mechanism 8 and its own weight as the number of blood collection tubes decreases. Then, it slides forward of the blood collection tube storage case 3.
As the remaining number of blood collection tubes in the blood collection tube storage case 3 is larger, the remaining amount detection slide plate 4 is located behind the blood collection tube storage case 3, but the remaining number of blood collection tubes in the blood collection tube storage case 3 is As the amount decreases, the remaining amount detection slide plate 4 moves to the front of the blood collection tube housing case 3.
The magnetic sensor 7 a provided on the substrate 7 detects the position of the remaining amount detecting slide plate 4 by the magnet 4 d provided on the remaining amount detecting slide plate 4 and sends the position information to the control device 70. In the illustrated embodiment, four magnetic sensors 7a are provided. Preferably, these four magnetic sensors 7a are equal to or the length of the magnet 4a provided on the remaining amount detection slide plate 4. It is arranged at narrower intervals. As a result, the magnet 4d of the remaining amount detecting slide plate 4 can be stopped across the two magnetic sensors 7a, so that the position of the remaining amount detecting slide plate 4 can be detected more finely. The control device 70 estimates the remaining amount of blood collection tubes in the blood collection tube storage case 3 based on the position information of the remaining amount detection slide plate 4 sent from the magnetic sensor 7a.
The remaining amount of blood collection tubes in the blood collection tube storage case 3 estimated by the control device 70 can be displayed on the monitor 81, for example.
Further, when the remaining amount of the blood collection tube falls below a predetermined value, that is, when the position of the remaining amount detection slide plate 4 exceeds a predetermined position, the control device 70 displays a monitor 81 or a warning lamp (not shown). Or the like can be used to warn that the remaining amount is low.
In this way, the remaining amount of the blood collection tube in the blood collection tube storage case 3 is constantly monitored, and if necessary, the remaining amount is displayed or a warning is issued. It is possible to prevent the blood collection tube from suddenly disappearing and the automatic blood collection tube preparation device from stopping. In addition, since it is possible to replenish the blood collection tube at an optimal timing that does not affect the processing, the replenishment operation of the blood collection tube does not lower the processing efficiency of the automatic blood collection tube preparation device.

As shown in FIG. 7, on the back surface of each blood collection tube storage case 3, two rows of magnetic block mounting portions 9 to which a magnetic block 10 for identifying each blood collection tube storage case 3 can be mounted are provided on the left and right. Yes. In the illustrated embodiment, five magnetic block mounting portions 9 are provided in one row.
A magnetic sensor 7b is provided at a position on the substrate 7 corresponding to the magnetic block mounting portion 9 of each blood collection tube storage case 3 (see FIGS. 9 to 12). In this embodiment, the blood collection tube housing case 3 is provided with two rows of five magnetic block mounting portions 9 on the left and right, and therefore the magnetic sensor 7b is also provided with two rows on the left and right. .
The blood collection tube housing case 3 is identified by a combination of mounting the magnetic block 10 to one row of the magnetic block mounting portion 9. Specifically, the blood collection tube housing case 3 is identified based on the combination of which position of the five magnetic block attachment portions 9 the magnetic block 10 is attached to and at which position the magnetic block is not attached. In the present embodiment, since there are five magnetic block mounting portions 9 in one column, a case type of 5 bits (32 types) can be identified.
The other row of the magnetic block mounting portion 9 is used for verification for error prevention. The magnetic block 10 is attached to the magnetic block attachment portion 9 of the other row under the conditions opposite to those of the first row. Specifically, when a magnetic block is attached to the magnetic block attachment portion 9 of one row, no magnetic block is attached to the corresponding magnetic block attachment portion 9 of the other row. When no magnetic block is attached to the magnetic block attachment portion 9 in the other row, the magnetic block is attached to the corresponding magnetic block attachment portion 9 in the other row (see FIG. 12).
Thus, by reversing the mounting conditions of the magnetic blocks 10 in the rows of the two magnetic block mounting portions 9, the magnetic sensor 7b compares the presence or absence of the magnetic blocks in the two rows and compares the magnetic blocks in the two rows. By determining whether the presence or absence of 10 is in the opposite state, it is possible to immediately confirm the misidentification due to the loss of the magnetic block and the failure of the magnetic sensor, and the control device 70 determines the type of the blood collection tube housing case 3. There is no misunderstanding.
If the type of the blood collection tube storage case 3 is misrecognized due to a missing magnetic block or a misidentification due to a failure of the magnetic sensor, this results in a mistake in taking the blood collection tube. However, as described above, the blood collection tube storage case 3 By providing the magnetic block row for identification and the magnetic block row for collation in this, it is possible to reliably prevent the type of the blood collection tube housing case 3 from being erroneously recognized.
The magnetic sensor 7 b reads the presence / absence of the magnetic block 10 in the magnetic block mounting portion 9 of the accommodated blood collection tube housing case 3 and sends the read information to the control device 70.
The control device 70 identifies the blood collection tube housing case 3 based on the combination of the presence / absence of the magnetic block 10 in the magnetic block mounting portion 9 in one row. In addition, the control device 70 associates the identification information (such as the type and size of the blood collection tube) of the blood collection tube stored in each blood collection tube storage case 3 in advance with the case identification information of each blood collection tube storage case 3. I remember it.
The control device 70 recognizes where the necessary blood collection tube is accommodated based on the case identification information read by the magnetic sensor 7b regardless of the accommodation position of the blood collection tube accommodation case 3.
For this reason, when the user pulls out some or all of the blood collection tube storage cases 3 and replenishes the blood collection tube storage cases 3 with each other, it remembers which blood collection tube storage case 3 is in which position. There is no need, and the blood collection tube housing case 3 after replenishment of the blood collection tube can be placed in an arbitrary place. As a result, the burden on the user when the blood collection tube is replenished is reduced, and problems such as a mistake in taking the blood collection tube due to a wrong insertion of the blood collection tube storage case 3 are eliminated.
In addition, the keyboard (not shown) associates the identification information (the type and size of the blood collection tube) of the blood collection tube stored in each blood collection tube storage case 3 with the case identification information of each blood collection tube storage case 3. ) Or a touch panel monitor 81 or the like, and can be arbitrarily set by the user.
Since the automatic blood collection tube preparation apparatus of the illustrated embodiment includes a total of eight blood collection tube storage cases 3, it can process eight types of blood collection tubes. In hospitals, blood collection tubes for outpatients and ward patients are prepared using an automatic blood collection tube preparation device, but the types of blood collection tubes to be prepared may differ between outpatients and ward patients. Specifically, for example, the Spitz tube is rarely used in the outpatient department, but the Spitz tube may be used in the ward. Thus, in order to cope with the preparation of different types of blood collection tubes, the number of the 8 blood collection tube storage cases may be insufficient. In addition, when performing a special test such as a nosocomial infection test, a special blood collection tube is often used to request an inspection from an external inspection organization. Even when such a special blood collection tube is used, the number of the eight blood collection tube storage cases may be insufficient.
Increasing the number of automatic blood collection tube labeling mechanisms increases the number of blood collection tube storage cases, but the number of automatic blood collection tube labeling mechanisms of the automatic blood collection tube preparation device for spitz tubes and special blood collection tubes that are not frequently used Increasing the number is undesirable from the viewpoint of cost and the size of the apparatus.
Like the automatic blood collection tube preparation apparatus in this embodiment, a magnetic block is provided in each blood collection tube storage case 3 to enable identification of the case, and the identification information of the blood collection tube stored in each blood collection tube storage case 3 (the blood collection tube) And the case identification information of each blood collection tube storage case 3 are associated with each other and stored in the control device 70, for example, the collection provided in the blood collection tube storage means 2 in advance. A larger number (for example, 10) of blood collection tube storage cases 3 than the number of blood vessel storage cases 3 (a total of 8 in this embodiment) is prepared, and the control device 70 has all 10 cases of the blood collection tube storage cases 3. If the identification information and the type of blood collection tube are stored in association with each other, special blood collection tubes, Spitz tubes, etc. can be processed simply by replacing the blood collection tube storage case 3 with another blood collection tube storage case as necessary. It becomes possible to do.

As shown in FIG. 7, an opening 3 b for the blood collection tube push-out means 11 is formed at the front end of the bottom surface of the blood collection tube storage case 3.

The direction detection sensor 22 is disposed above the delivery cam 21. The sensor 22 detects the direction of the blood collection tube in the delivery cam 21 and sends the information to the printer 23 via the control device 70.
The printer 23 prints necessary information on the label in accordance with the direction of the blood collection tube based on the information detected by the sensor 22. The necessary information printed on the label is specifically information related to the patient corresponding to the blood collection tube to which the label is to be attached, and more specifically, for example, associated with the patient ID or the patient ID. Sample ID and the like. Information about this patient is sent from the control device 70. Information about the patient is printed on the label in a readable form such as a barcode and / or characters and symbols.
On the other hand, after the direction of the blood collection tube is detected by the sensor 22, the delivery cam 21 rotates, and the blood collection tube is dropped from the delivery cam 21 onto the pressurization table 27. Next, the pressurization table 27 moves the blood collection tube upward. The pushed-up, blood collection tube is supported at three points by a pressure table 27, a sticking roller 26, and an auxiliary roller 28.
In this state, the sticking roller 26 is rotated, whereby the blood collection tube is rotated and the printed label is attached to the surface of the blood collection tube.
When the application of the label is completed, the pressurization table 27 is lowered, and the blood collection tube falls on the discharge conveyor 40 below the pressurization table 27.

The blood collection tube discharge conveyor 40 extends in the horizontal direction across the two automatic blood collection tube labeling mechanisms 1 and onto the tray transfer conveyor 61 of the blood collection tube collection mechanism 60.
All the blood collection tubes to which the printed labels are attached by the two automatic blood collection tube labeling mechanisms 1 are dropped onto the discharge conveyor 40 and are carried to the blood collection tube collection mechanism 60 by the discharge conveyor 40.

The tray transfer conveyor 61 transfers the empty tray supplied from the empty tray storage unit 62 to the collection position. At the collection position, when the blood collection tube for one patient, the blood collection instruction, and if necessary, the label for manual pasting is put into the empty tray, the tray transfer conveyor 61 moves the collected tray to the front of the automatic blood collection tube preparation device. To the first tray housing part 63 or the second tray housing part 64.
The first tray accommodating portion 63 is provided adjacent to the front of the empty tray accommodating portion 62, and is configured to accommodate the collected trays stacked in the vertical direction. The first tray accommodating portion 63 lifts the collected tray on the tray transfer conveyor 61 upward by a nail or the like (not shown) and accommodates it inside.
The 2nd tray accommodating part 64 is arrange | positioned so that it may extend along the width direction ahead of the blood-collecting-tube automatic preparation apparatus.
Specifically, the second tray accommodating portion 64 is formed of a passage having a width capable of accommodating a tray formed on the upper end surface of the blood collection tube accommodating means 2 in the two automatic blood collection tube labeling mechanisms 1. Each automatic blood collection tube labeling mechanism 1 includes a label printing pasting unit 20 above the blood collection tube storage unit 2, and the label printing pasting unit 20 is arranged behind the automatic blood collection tube preparation device. Thus, a space is formed above the blood collection tube storage means 2. A second tray housing portion 64 is provided in a space formed above the blood collection tube housing means 2.
The second tray accommodating portion 64 is configured such that one end thereof extends to the tray transfer conveyor 61, and the collected tray is extruded from the tray transfer conveyor 61 to the second tray accommodating portion 64 by the tray pushing means 66. ing. In the illustrated embodiment, the second tray accommodating portion 64 is configured with a length that can accommodate three recovered trays.
With the configuration described above, the collected tray obtained by collecting the blood collection tube after labeling for each patient is selectively accommodated in either the first tray accommodating portion 63 or the second tray accommodating portion 64.
The second tray housing portion 64 is disposed above the blood collection tube housing means 2 and on the front side of the blood collection tube automatic preparation device. In this way, the automatic collection device for blood collection is enlarged by providing the storage portion for the collected tray above the collection tube storage means 2 in the automatic collection device for blood collection and on the front side of the automatic collection device for blood collection. Therefore, the collected tray can be stored in a place where the user can easily take it out.
The allocation of the collected trays to the first tray accommodating portion 63 and the second tray accommodating portion 64 includes, for example, a ward tray that is not used immediately in the first tray accommodating portion 63 and the second tray accommodating portion 64. It is conceivable to store an outpatient tray to be used immediately.

Each of the enlarged views of the comb-shaped rack is shown.
As shown in the drawing, the second transfer means 35 includes a guide member 36 extending in a substantially horizontal direction so as to cross the transfer conveyors 31L and 31R extending vertically in the first transfer means 30L and 30R, and along the guide member 36. And a comb-shaped rack 37 provided so as to be movable in the lateral direction.
The comb rack 37 of the second transfer means 35 has a shape capable of rubbing against the comb rack 32 of the first transfer means 30, and the comb rack 32L (or 23R) of the first transfer means 30L (or 30R). ) And a position that rubs against the comb rack 32R (or 32L) of the other first transfer means 30R (or 30L).
When the comb-shaped rack 37 of the second transfer means 35 is positioned below the comb-shaped rack 32 on which the blood collection tube of the first transfer means 30 is mounted, the transfer conveyor 31 of the first transfer means 30 is rotated in reverse. The comb rack 32 of the first transfer means 30 is lowered downward. Then, when the comb rack 32 of the first transfer means 30 rubs against the comb rack 37 of the second transfer means 35, the comb rack 32 of the first transfer means 30 moves to the comb rack 37 of the second transfer means 35. The blood collection tube is transferred.
After the blood collection tube is transferred from the comb rack 32 of the first transfer means 30 to the comb rack 37 of the second transfer means 35, the comb rack 37 of the second transfer means 35 is moved to the other first transfer means 30. Move to transfer conveyor 31.
In this state, when the transfer conveyor 31 of the other first transfer means 30 is driven in a normal rotation, the comb-shaped rack 32 of the other first transfer means 30 moves upward. Then, when the comb rack 32 of the other first transfer means 30 rubs against the comb rack 37 of the second transfer means 35, the comb rack 37 of the second transfer means 35 to the comb rack of the first transfer means 30. The blood collection tube is moved to 32.

Hereinafter, the operation of the second transfer means 35 configured as described above will be described more specifically.
The comb rack 37 of the second transfer means 35 is normally positioned between the two transfer conveyors 31L and 31R of the first transfer means 30.
For example, while the label printing sticking means 20R of one automatic blood collection tube labeling mechanism 1R cannot be used due to a failure or the like, the collection collected in the blood collection tube storage portion 2R of the automatic blood collection tube labeling mechanism 1R. When a blood vessel is used, the blood collection tube is taken out from the corresponding blood collection tube storage case 3R of the automatic blood collection tube labeling mechanism 1R using the blood collection tube pushing means 11R, and the first transfer conveyor 30R of the automatic blood collection tube labeling mechanism 1R is used. A blood collection tube is placed on the comb-shaped rack 32R. Next, the first transfer conveyor 30 </ b> R is driven to rotate in the forward direction, and the comb-shaped rack 32 </ b> R on which the blood collection tubes are placed is once conveyed above the second transfer means 35.
Next, the comb rack 37 of the second transfer means 35 is moved to the first transfer conveyor 31R of the first transfer means 30R. Thereafter, the first transfer conveyor 31R is driven in the reverse direction to lower the comb rack 32R on which the blood collection tubes are placed, and the comb rack 32R of the first transfer conveyor 31R is moved to the comb rack of the second transfer means 35. Rub with 37. As a result, the blood collection tube placed on the comb-shaped rack 32R of the first transfer conveyor 31R is replaced with the comb-shaped rack 37 of the second transfer means 35. The second transfer means 35 is a comb-shaped carrying a blood collection tube. The rack 37 is moved to the first transfer means 30L of the other automatic blood collection tube labeling mechanism 1L.
Thereafter, the first transfer conveyor 31L of the other automatic blood collection tube labeling mechanism 1L is driven to rotate forward, and the comb rack 32L is raised upward. Thereby, the comb-shaped rack 32L of the first transfer conveyor 31L rubs against the comb-shaped rack 37 of the second transfer means 35, and the blood collection tube placed on the comb-shaped rack 37 of the second transfer means 35 is It is placed on the comb-shaped rack 32L of one transfer means 30L.
Thereafter, the other automatic blood collection tube labeling mechanism 1L is operated as usual, and the label printing processing of the blood collection tube is performed.
As described above, the second transfer means 35 is used to transfer the other automatic blood collection tube labeling mechanism 1L (or from the first transfer means 30R (or 30L) of one automatic blood collection tube labeling mechanism 1R (or 1L). 1R) is configured so that the blood collection tube can be moved to the first transfer means 30L (or 30R), whereby the label printing sticking means 20R (or 20L) of one of the blood collection automatic labeling mechanisms 1R (or 1L) is provided. ) Cannot be used due to a failure or the like, the blood collection tube stored in the automatic blood collection tube labeling mechanism 1R (or 1L) can be used to prepare the blood collection tube. Even if the sticking means 20R (or 20L) cannot be used due to a failure or the like, the processing can be continued without stopping the processing of the entire apparatus.
Further, the rack 32 of the first transfer means 30 and the rack 37 of the second transfer means 35 are both formed in a comb shape, and the blood collection tubes are replaced by rubbing them together, thereby collecting the blood collection tubes. The configuration for replacing the blood vessels can be simplified.

In the above description, when the label printing application means 20R of one automatic blood collection tube labeling mechanism 1R becomes unusable due to a failure or the like, the automatic blood collection labeling mechanism 1R is used by using the second transfer means 35. An example has been described in which the accommodated blood collection tube is transferred from the first transfer means 30R of the automatic blood collection tube labeling mechanism 1R to the first transfer means 30L of the automatic blood collection labeling mechanism 1L.
However, the second transfer means 25 is not limited to the case where the label printing sticking means 20 of the automatic blood collection tube labeling mechanism 1 is out of order. For example, an order to the blood collection tube housed in one automatic blood collection labeling mechanism 1R is provided. It can also be used when the concentration is concentrated.
Specifically, when orders for blood collection tubes housed in one automatic blood collection tube labeling mechanism 1R are concentrated, all the blood collection tubes are processed by the label printing pasting means 20R of the automatic blood collection tube labeling mechanism 1R. Instead, the second transfer means 35 is used to transfer some of the blood collection tubes from the first transfer means 30R of the automatic blood collection tube labeling mechanism 1R to the first transfer means 30L of the automatic blood collection labeling mechanism 1L. If the second transfer means 30R is operated so that the label print sticking means 20L of the blood collection automatic label sticking mechanism 1L also performs processing, the processing speed of the entire apparatus can be improved.
