Abstract

PURPOSE:To reduce the residual amount of a liquid when the liquid in a bag has been exhausted and to reduce the waste amount of medical fluid by forming a bag port for medical treatment making the form of the base end in a wedge form cutting the side surfaces obliquely from two opposite directions. CONSTITUTION:The base end 2 of a port 1 is made in a wedge form by cutting the side surfaces obliquely from the front side and the rear side, to form two oblique surfaces 3 and 4. And, inside the port 1, a diaphragm 5 is furnished. By fixing the port 1 to face the two oblique surfaces 3 and 4 of the port base end 2 to the rear side of a bag, bag sheets 6 and 7 are contacted almost closely to the oblique end surfaces when the bag is made empty. The port 1 can be used favorably for a bag for medical treatment such as a blood bag, a fluid transfusion bag, a peritoneum dialysis bag, and the like. The port and the bag can be fixed by a heat fusing in the same manner as the conventional way.

In the case of blood bags, when the blood in the bag is separated into blood cell components and plasma components by centrifugation, these two components
The blood adhering to part 5 remained even after centrifugation, and the supernatant plasma component was often mixed with the plasma component when it was discharged from the bag. In such a case, it is necessary to perform centrifugation again. Furthermore, when injecting liquid into an empty bag, there is a problem in that a relatively large amount of air enters the bag due to the air that initially collects in the area 25.

In the present invention, the above-mentioned problem is solved by forming the proximal end of the port into a specific shape. That is, the first invention is a cylindrical port installed in a medical bang for introducing and introducing fluid, and the shape of the proximal end is wedge-shaped by cutting the side surfaces diagonally from two opposing directions. This medical bag port is characterized by its shape. Further, the second invention provides such a port with a wedge-shaped proximal end portion.
This medical bag is characterized in that two oblique end surfaces are sandwiched and fixed between sheets so as to face the front and back sides of the bag, respectively.

FIG. 3 is a side sectional view showing the port 1 attached to a medical bag. In the figure, 6 and 7 are sheets constituting the bag, 9 and 10 are port covers, and 11 is a peel tab for opening the port cover. Port 1 is fused and fixed together with the bag sheet and port cover at part 8. As shown in the figure, by fixing the two diagonal end surfaces 3 and 4 of the proximal end of the port so that they face the front and back sides of the bag, the bag sheets 6 and 7 can be attached to these diagonal surfaces when the bag is empty. It almost sticks to the edge. Therefore, as can be seen from the figure, the space 25 shown in FIG. 8 is less likely to be formed, and the above-mentioned problem does not occur.

The port of the present invention can be suitably used in medical bags such as blood bags, infusion bags, and peritoneal dialysis bags. As for its manufacturing method, it can be manufactured by cutting the proximal end of a conventional port into a wedge shape, or it can be manufactured from the beginning by molding into a wedge shape. Further, the port and the bag can be fixed by heat fusion as in the past, and when the material is vinyl chloride resin, high frequency fusion is suitable.

According to the present invention, no extra space is created at the proximal end of the port when the bag is emptied, so when the liquid in the bag is drained, there is less remaining liquid, and the amount of wasted chemical liquid is reduced. Become. Furthermore, when used in blood bags, the rate of re-centrifugation due to residual blood adhering to the top of the bag during centrifugation is reduced, making work more efficient. Another advantage is that the amount of air that accumulates in the upper part of the bag when a medical solution is injected into the bag is reduced.
