Abstract

PURPOSE:To completely prevent a blood bag from being punctured in the case of a centrifugal separation processing and to obtain the blood bag with the satisfactory disentangled state of blood platelets by forming a projecting part on the inside of a bag-shaped main body and forming a blood housing room over the upper and lower sides of an extension line in the tip of the projecting part. CONSTITUTION:On the inside of a main body 2, a thick projecting part 12 is formed and over the upper and lower sides of an extension line 0 in the tip of the projecting part 12, a space is spread to form a blood housing room 13. The projecting part 12 is formed while setting width W1 in the range of 0.6mm to 1.2mm and setting thickness D1 in the range of 0.8mm to 1.4mm. The width W1 and the thickness D1 is gradually formed to be large from 0.6mm to 1.2mm toward a bottom part B in the range of a size and the thickness D1 is also gradually formed to be large from 0.8mm to 1.4mm from a side part S to a corner part R and the bottom part B.

The blood bag is formed by sandwiching two sheets made of flexible synthetic resin between an upper mold having a bag edge shape and a flat plate (lower mold) and welding them using high frequency. was.

夫もされていたが、調整が困難であった。However, as shown in FIG.
Only the upper side 23 of the bag-like main body 22 was swollen, and the lower side 24 was flat. Further, near the welding part 25 on the peripheral edge of the main body 21, there were few protruding parts 26 (resin reservoirs) of vA fat, and the wall tended to be thin (the protruding parts 26 usually have a width W2 of 0.000.
For this reason, when the blood bag 20 is centrifuged to separate blood components, the welded parts are likely to peel off and the bank etc. There was a risk that this would occur. In addition, the volume of the blood storage chamber formed inside the bag-like body was small, and when loosening the platelets separated by centrifugation and settling at the bottom of the body, it was difficult to loosen the platelets due to stirring. If the platelets were to be forcibly loosened and collected, there was a risk that the platelets would be destroyed. Further, as in the blood bag 30 shown in FIG. 5, attempts have been made to make the protruding portion 36 thicker so that the main body 32 is inflated, but this adjustment is difficult.

Two flexible synthetic resin sheets (19, 20) are sandwiched between an upper mold 16 having a groove 17 corresponding to the shape of the bag-like body 2 of the bag and a high frequency The present invention provides a method for manufacturing the blood bag 1 according to the first invention, which is welded.

すい。[Function] The protruding portion 12 formed inside the peripheral edge of the bag-like main body 2 can be formed thicker, and the welded portion 11 has a thicker wall thickness, so that centrifugal force can be applied when separating blood components. There is no risk of the bag-like main body 2 being banked even if the blood storage chamber 13
Because it is widely formed, it is easy to stir, and the fluidity of air is good, making it easy to loosen platelets that have settled in plasma, for example.

A bag-like main body 2 made of flexible synthetic resin, a connecting tube 4 loaded with a communicating piece 3 at the upper end of the main body 2, and a blood outlet 6 covered with a protector 5. A welded portion 11 is formed at the outer edge of the main body 2, which is composed of a liquid transfer tube 8 to which a blood collection needle 7 is attached, and a connection tube 10 to a blood component separation bag 9.

In other words, the width W1 gradually decreases from the side S to the corner R1 and the bottom B.・Thick from 6mm to 1.2mm (formed and thickened, gradually becoming 0.8m from side S to corner R1 bottom B)
It is preferable to form it large from m to 1.4+am.

As shown in the figure, first, an upper mold 16 in which a groove 14 corresponding to the shape of the blood bag 1 and the main body 2 and an edge mold 15 of the main body 2 are formed, and a lower mold in which a mold 17 corresponding to the shape of the main body 2 is formed. Two flexible synthetic resin sheets 19.2 are placed between the mold 18 and the mold 18.

しやすくなり、肉厚の突出部１２を形成しやすくなる。By lowering the upper mold 16 and applying high frequency electricity, the resin constituting the sheet 19.20 is melted, and the molten resin flows up and down due to the pressing force of the mold 16.18.
(Since the groove 17 corresponding to the shape of the main body 2 is also formed in the lower mold 18, the molten resin can easily flow out in the direction of the groove 17, making it easier to form the thick protrusion 12.

ことを確認できた。Next, the communicating piece 3 is broken, the supernatant plasma component is stored in the blood component separation bag 9 via the connecting tube IO, and the bag 9 is centrifuged again under predetermined conditions to separate the plasma components. platelets are precipitated. The bag 9 is placed on a shaking rock and the platelets precipitated at the bottom of the bag 9 are loosened and collected while being vibrated. During centrifugation, the protrusion 12 is formed thickly, so it is confirmed that no banks occur at all, and when loosening platelets, the blood storage chamber is formed wide, making it easy to stir. It was confirmed that the loosening condition was good.
