[Prior art and its problems]

 As one of the means for treating diseases such as rheumatoid arthritis and systemic lupus erythematosus and reducing the symptoms, a plasma cold filtration method as shown in FIG. 3 has been proposed.

The plasma cooling filtration method will be described with reference to FIG. 3. Blood is sent from its supply source to the primary filter 3 through the blood supply line 2 by operating the blood pump 1, where it is converted into blood cells and plasma. The separated blood cells are sent to the blood cell return line 4 side for remixing with the purified plasma described below.

On the other hand, plasma is sent from the plasma supply lines 6a and 6b to the secondary bag 8 through the cooling bag 7 on the plasma supply lines 6a and 6b, where it is filtered. The plasma is cooled to 4 to 25 ° C., preferably around 4 ° C. in the bag section 7, and the cryogel of the high molecular weight substance produced by this cooling is removed from the plasma by the filtration treatment by the secondary filter 8. To be removed. The filtrate from the secondary filter 8, that is, purified plasma, is returned to the purified plasma return line 9 while being heated to the initial liquid temperature in the heating bag 10, and further, the blood cells returned from the primary filter 3 are returned. It is remixed and returned to the source. Since the secondary filter tends to become clogged while continuing plasma filtration, a cleaning line 11 is attached to the filter 8 and a cleaning pump 12 is installed in the middle of the line 11.

Besides, in the figure, 13, 14, 15 are drip chambers.

FIG. 4 schematically shows the entire automatic blood processing apparatus applied to the implementation of the above-mentioned filtration method, in which various operation parts are provided on the front upper part 17 connected to the rear end of the flat part 16 provided on the front. A throat is provided, and a blood circuit integrated tray 19 (shown by a one-dot chain line) is attached to a lower portion 18 of the front surface connected to the front end of the flat portion 16. Furthermore, the blood pump 1, the plasma pump 5, and the washing pump 12 shown in FIG. 3 are sequentially installed on the flat surface portion 16 from the left side. In the other figures, 20 is a cooling part of the cooling bag 7, 21 is a heating part of the heating bag 10, 22 is a holder for the first filter 3, and 23 is a holder for the second filter 8.

FIG. 5 schematically shows an entire blood circuit integrated tray 19 used by being attached to the lower front surface 18 of the automatic plasma cooling / filtering apparatus (see FIG. 4), and the tray body 19a is a relatively hard plastic thin plate. The blood circuit is divided into five blocks, that is, a blood line 2, a plasma line first half 6a, a plasma line second half 6b, a washing line 11, and a return line 4, 9 on the front surface thereof.

The line is made of a flexible and elastic plastic tube. On the front surface of the tray body 19 a, there are fastening portions 24 for stopping the line at various points, and a drip chamber 13 incorporated in the line. The fastening portions 25, 26 and 27 of 14, 14 and 15 are formed respectively.

Among the above lines, in the middle of the blood line 2, the first half 6a of the plasma line, and the washing line 11, the blood pump 1, the plasma pump 5, and the washing pump 5 mounted on the flat portion 16 of the device shown in FIG. Since it is necessary to dispose the pump 12, the middle of the equal lines 2, 6a, 11 is curved and projected upward from the upper end of the tray main body 19a, and the pump 1. It is designed to receive the operations of 5 and 12.

The blood circuit integrated tray 19 is attached to the lower part of the front surface of the apparatus shown in FIG. 4, the first and second filters 3 and 8 are attached to the holders 22 and 23, the cooling bag 7 is attached to the cooling section 20, and the heating is performed. As shown in FIG. 3, the heating bag 10 is installed in the portion 21 and then the ends of the lines accumulated in the tray body 19a are connected to the first and second filters 3.8 and the cooling bag 7. The entire circuit can be constructed.

The blood circuit integrated tray 19 is transported and stored in a packaging bag 31 as schematically shown in FIG. 6. During transportation and storage, the blood circuit integrated tray 19 of the lines 2, 6 a and 11 is stored. The curved protrusions 28, 29, 30 have a fold, which causes a narrowed portion in the duct, which causes a problem that blood, plasma, and washing liquid cannot be normally sent during use.

The present invention has been made for the purpose of eliminating such conventional problems.

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. The same reference numerals denote the same parts throughout the drawings.

FIG. 1 is an overall schematic explanatory view showing one embodiment of the present invention, in which an extension 32 extends upward from an upper end of a tray body 19a and a curved protrusion 28, 29, via a cutoff 33. The extension 32 is provided with a fastening portion 34, 35, 36 for detachably fastening and restraining the top of the curved projection 28, 29, 30. There is.

The structure of the fastening portions 34, 35, 36 is not particularly limited as long as it has a configuration that allows the curved projections 28, 29, 30 to be detachably fastened and restrained, and constitutes, for example, a circuit. A grooved fastening is suitable which fits the flexible elastic plastic tube in frictional engagement.

The cut-off portion 33 is used to cut-off and remove the extended portion 32 as appropriate, and for example, a cut is formed in a dodge shape along the cut-off line or a thin-walled portion is formed along the cut-off line. The one with the configuration such as is applied.

Since the extension portion 32 has a function of protecting the curved protrusions 28, 29, 30 from being deformed by an external force during transportation and storage, the curved protrusions 28, 29, 30 are kept in a normal state where they cannot be bent forever. Can be held at

In use, the extension portion 32 is cut and removed based on the cut portion 33, so that the blood circuit integrated tray is attached in a conventional manner, for example, to an automatic plasma cooling / filtering device (see FIG. 4). Can be used.

FIG. 2 is an overall schematic explanatory view showing an example of another embodiment of the present invention. In this embodiment ^, the extension height of the extension 32 ^, is the curved protrusions 28, 29 ,. 30 height by remote small protrusion, Thus to curved protrusions 28, 29, 30 fastening part 34 in a state obtained by subtracting the protrusion ^{height, 35, 36,} since the configuration is secured ing.

In the present embodiment, the fastening portion 35 for the center of the curved protrusion ^29, is provided transversely central upper portion in the extension ^32,該止attachment part ^35, the central curved protrusion 29 It is possible to reduce the protruding height by fixing and restraining the top part while pressing it downward.

Furthermore extensions 33 longitudinal direction fastener part 34 to two parallel to the top center ^{of,,, 36,} are provided,該止attachment part ^34, 36 on both sides of the curved protrusions 28, ^30, It is possible to reduce the protruding height by fixing and constraining in a state where a loop is formed as shown in the figure.

[0023] Thus, by reducing the projecting height of the curved protrusions 28, 29, 30, this and the like can be an extension 33 of smaller extension ^height, fit well within.

In this embodiment ^{, since} the extension height of the extension portion 33 can be made smaller, the size of the stacking tray body can be made smaller than that of the embodiment shown in FIG.

[0025]

[Effect of device]

 Since the blood circuit integrated tray of the present invention can protect the curved protruding portion of the circuit protruding upward from the upper end of the tray main body from an external force by the extension extending upward from the upper end of the tray main body, it can be curved during transportation and storage. The protruding parts will not be bent, and blood, plasma, cleaning liquid, etc. can be sent normally during use.

In addition, since the extension portion can be easily cut and removed upon use, based on the cut portion, it is easy and convenient to use.
