Double-mouth pipe of transfusion bag

Abstract

The invention provides a double-mouth pipe of a transfusion bag. The double-mouth pipe comprises a medicine distribution pipe and a transfusion pipe, wherein the medicine distribution pipe and the transfusion pipe are vertically fixed on a double-pipe body seat; a medicine distribution pipe through hole and a transfusion pipe through hole are separately arranged on the medicine distribution pipe and the transfusion pipe; the aperture of the medicine distribution pipe through hole is smaller than that of the transfusion pipe through hole; a gasket is arranged inside the top end of the medicine distribution pipe through hole; a rubber plug is placed on the gasket; two sides of the double-pipe body seat are in an elongated and thin wing shape, and four corners of the double-pipe body seat are all chamfers; and multiple convex ribs are arranged outside the double-pipe body seat. The double-mouth pipe of the transfusion bag has the advantages that: the transfusion pipe and the medicine distribution pipe are separated, thus cross infection is avoided when medicine liquid is used; the aperture of the medicine distribution pipe hole is smaller than that of the transfusion pipe hole, thus the material consumption is reduced and the production cost is lowered; and two sides of the double-pipe body seat are in an elongated and thin wing shape, and four corners of the double-pipe seat are all chamfers, thus bag breakage and liquid leakage caused by excessive extension of the membrane at the transfusion bag joint are avoided.

Description

technical field [0001] The invention relates to the technical field of medical packaging, in particular to a double-mouth tube of an infusion bag. Background technique [0002] In today's medical field, infusion to patients has become a frequently used medical method, so the amount of infusion container or infusion bag is very large; because the infusion bag is light in weight and easy to transport, it has been widely used. Most of the existing medical infusion bag interfaces are single-tube interfaces. Since the infusion and drug dosing share a catheter, it is easy to cause cross-contamination. [0003] In order to make the infusion bag mouth and the connection port welded firmly, two wings are made at the connection end of the connection port. The walls of the two wings are too thick in the prior art, and the heating is uneven when the connection port and the infusion bag are connected and heat-sealed, which affects the heat-sealing quality and will Water leakage and se...

[0003] In order to make the infusion bag mouth and the connection port welded firmly, two wings are made at the connection end of the connection port. The walls of the two wings are too thick in the prior art, and the heating is uneven when the connection port and the infusion bag are connected and heat-sealed, which affects the heat-sealing quality and will Cause water leakage and seepage, and cause material waste and high cost
