Three-cavity sterile bag and preparation method thereof

Abstract

The invention discloses a three-cavity sterile bag and a preparation method thereof. The square sterile bag consists of a double-cavity inner bag and an outer packaging bag, wherein the double-cavity inner bag is formed by welding horn-shaped liquid filling ports, arc-shaped insufficient soldering strips with opening points, thermal transfer with independent cavities, hanging holes, an A liquid medicament cavity, an intermediate liquid medicament cavity, a C liquid medicament cavity, three-cavity bag sides, three-cavity bag corners, straight-strip sealing grids, a medicament delivery plug and a medicament feeding plug into a whole through heat seal; and one side of the outer packaging bag is provided with an outer packaging bag welding edge and an outer packaging bag opening mouth. The preparation method of the sterile bag comprises the steps of bag molding, preparation of filling junctions of the bag, filling, lamp inspection, packaging and sterilization. The three-cavity sterile bag is simple in structure and easy to operate; and for the insufficient soldering of the bag, scientific external force opening points are designed, so that the insufficient soldering of the bag is more operable.

Description

A three-chamber aseptic bag and its manufacturing method technical field The invention relates to an infusion bag, in particular to a three-cavity aseptic bag and its manufacturing method Background technique In clinical practice, if a patient needs to infuse multiple different infusions at the same time, it is generally adopted to mix a variety of single different products before use. Different single varieties are taken out and mixed evenly, and then the mixed medicinal liquid is input into the human body. However, "sterility" is an absolute concept by definition, but unfortunately, in today's highly developed science and technology, absolute sterility can neither be achieved nor verified. Above, this method of mixing increases the chances of the drug being contaminated with microorganisms. At the same time, due to the high construction and operating costs of the aseptic dispensing room, it is difficult to establish a sterile dispensing room in general hospitals. Simu...

Problems solved by technology

However, "sterility" is an absolute concept by definition, but unfortunately, in today's highly developed science and technology, absolute sterility can neither be achieved nor verified.

Above, this hybrid approach increases the chances of drug products being contaminated with microbiological risks

At the same time, due to the high construction and operating costs of the sterile dispensing room, it is difficult to establish a sterile dispensing room for general hospitals

At the same time, it also hinders the promotion of mixed infusion methods with therapeutic advantages

Moreover, taking the medicine multiple times will result in multiple punctures of the rubber stopper, which may cause the risk of particle contamination of the infusion product due to repeated friction between the rubber stopper and the insertion needle, and at the same time, the production and use costs are relatively high

But now the medical multi-cavity bag mixed liquid bag that has been used has a complicated manufacturing process. Generally, a single-layer film is folded into double parts, and the infusion tube mouth is welded to make a bag, and then through the side or back, the A variety of different liquid medicines are poured into each chamber in the bag, and sealed into a multi-chamber bag by high-temperature welding

There are also many production processes, and the inner layer in contact with the liquid medicine is directly exposed to the air during bag making, which affects the stability of the final product quality

And part of the filling port is closed, and the gas content of the open-type potting to protect the liquid medicine in the bag is difficult to control, and the production cost is also high
