Interface welding mould of transfusion soft bag

Abstract

The present invention discloses an interface welding mould of transfusion soft bag, including upper shoe and lower shoe formed by locking, the lower shoe is provided with lower welding mould and lowerheating pipe, the upper shoe is provided with external welding mould, upper heating pipe and inner movable welding mould, which is covering arranged in the external welding mould and capable of doingup and down movement, the lower welding mould, external welding mould and inner movable welding mould together composing the interface welding surface of the transfusion soft bag. The invention is interface welding mould of transfusion soft bag with simple and compact structure, low cost, wide application and capable of improving welding accuracy for improving transfusion soft bag products quality.

Description

technical field [0001] The invention mainly relates to the field of medical packaging equipment, in particular to an interface welding mold for soft infusion bags. Background technique [0002] Existing large transfusion soft bags need to be welded at high temperature for many times between the plastic film dedicated to the soft bag and plastic interfaces of various shapes to ensure that the plastic film and the plastic interface are welded firmly and prevent the problem of false welding from causing waste. However, the existing upper and lower interface welding molds for infusion soft bags are symmetrically designed according to the cross-sectional shape of the welded part, and the interface welding mold has no floating self-adaptability. The external dimensions of the interface need to be highly consistent, which puts high demands on the manufacture of plastic interfaces. Therefore, at this stage, most manufacturers of soft bag infusion solutions use imported plastic inte...

Problems solved by technology

However, the existing upper and lower interface welding molds for infusion soft bags are symmetrically designed according to the cross-sectional shape of the welded part, and the interface welding molds have no floating self-adaptability. The external dimensions of the interface need to be highly consistent, which puts high demands on the manufacture of plastic interfaces

Therefore, at this stage, most manufacturers of soft bag infusion solutions use imported plastic interfaces, which increases the production cost a lot.

However, if the domestic plastic interface is used due to its low manufacturing precision, the qualified rate of the product will be reduced, and at the same time, there is a possibility that the liquid medicine may deteriorate during storage, which seriously affects the life safety of users.
