Description

A medical composite film soft bag

Technical Field

The utility model relates to the technical field of medical soft bags, in particular to a medical composite film soft bag.

Background Art

All sources of nutrition or nutritional supplements are provided to patients who cannot eat normally, especially those who cannot tolerate large-volume feeding or require high energy. It is suitable for the following situations: preoperative preparation for patients with high catabolic conditions, limited fluid intake (such as patients with heart failure), cachexia, anorexia, recovery period, chewing or swallowing difficulties, and malnutrition; it is not very convenient to give enteral nutrition to patients at work; there are two types of enteral nutrition commonly used in hospitals:

1. Before use, you need to shake the bottle, then open the bottle cap with a wine opener, replace it with a rubber bottle cover, and give it to the patient. However, it is bottled and fragile during operation, and a small amount of liquid medicine will stick to the bottle wall, causing waste. It also has a lid and needs to be opened with a wine opener, which increases the workload on the one hand and fails to meet the sterility requirements on the other hand.

2. Some patients use short peptides, and it is even more difficult to find their containers; use a 500ML 0.9% sodium chloride liquid bag, pour the brewed short peptide solution into the 500ML 0.9% sodium chloride liquid bag. Although this method is convenient for our work, 500ML of saline is just poured out, which is a waste. Secondly, the liquid bag needs to be cut open with scissors, and then the liquid is poured out, and then the brewed enteral nutrition is poured in. Finally, find something to cover the incision to prevent leakage. This method has many disadvantages, namely, it increases the workload, cannot be sterile, and will cause nutrient loss;

To address this, the present application proposes a medical composite film soft bag.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

1-3, a medical composite film soft bag comprises a soft bag body 1, one end of the soft bag body 1 is connected to an infusion nozzle 2, a rubber plug 3 is installed on the infusion nozzle 2, the end of the soft bag body 1 opposite to the infusion nozzle 2 is open, the open end of the soft bag body 1 is sealed by a leak-proof double-layer zipper structure, the leak-proof double-layer zipper structure is a double-track sealing strip 4, an empty section 9 is provided between the double-track sealing strip 4, the double-track sealing strip 4 can seal the open end by pressing the soft bag body 1, which is a common sealing structure of some sealed bags on the market; wherein, the four corners of the soft bag body 1 are chamfered to prevent sharp end corners from scratching medical staff.

The material of the soft bag body 1 is a composite film, which includes an inner layer 11, a middle layer 12 and an outer layer 13. The inner layer 11 and the middle layer 12 are connected, and the middle layer 12 and the outer layer 13 are connected. Among them, the material of the inner layer 11 is polyethylene film, which is a completely non-toxic inert polymer, chemically stable, and will not fall off or degrade into foreign matter; the material of the middle layer 12 is polypropylene film, which is a dense material with excellent water and air barrier properties; the material of the outer layer 13 is polyamide film, which is mainly used to improve the mechanical strength of the soft bag.

Among them, an integrated first connecting strip 5 is connected to the soft bag body 1, a female buckle 6 is installed on the first connecting strip 5, a second connecting strip 7 is connected to the soft bag body 1, a sub-buckle 8 is installed on the second connecting strip 7, the first connecting strip 5 is connected to one side of the soft bag body 1, and the sub-mouth 8 is located on the other side of the soft bag body 1. When the female buckle 6 is buckled on the sub-buckle 8, as shown in Figure 3, the empty section 9 is in a bent state at this time, which can further improve the sealing effect of the double-track sealing strip 4 and prevent the double-track sealing strip 4 from being opened due to excessive liquid weight and the liquid from spilling.

When using the utility model, medical staff open the double-track sealing strip 4, and only need to pour the nutrient solution to be used into the soft bag body 1 through the open end, and then seal it through the double-track sealing strip 4, so that the sterility requirement can be guaranteed, and time and labor can be saved during the operation; if the patient has high sodium, warm water can also be given to the patient, which is convenient and can achieve sterile operation;

Secondly, the soft bag body 1 of the composite film does not contain plasticizers, and there is no risk of DEHP leakage; the water vapor permeability is extremely low, so the infusion concentration remains stable and the storage period of the product can be guaranteed; the gas permeability is extremely low, even very unstable infusions can be well preserved and have good thermal stability.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
