Description

Technical Field

[0001] The utility model belongs to the technical field of composite film bags, in particular to a medical composite film bag. Background Art

[0002] Traditional medical sterilization self-sealing bags are composed of medical composite membrane and medical dialysis paper from top to bottom. The two are connected by three edges of hot ironing to form a U-shaped cavity. The opening of the U-shaped cavity is the bag mouth. The medical dialysis paper at the bag mouth extends outward as a whole over the medical composite membrane to form a sealing tongue. A double-sided tape is attached to the sealing tongue. The double-sided tape is composed of release paper and double-sided adhesive strips. The double-sided tape and the medical composite membrane are on the same side of the medical dialysis paper. This double-sided tape can play a role in sealing the packaging bag. When using it, you only need to fold it along the specified folding line, peel off the release paper on the double-sided tape, and then use the double-sided adhesive strips of the double-sided tape to stick the medical composite membrane and medical dialysis paper at the bag mouth. The bag mouth can be sealed without the help of other sealing equipment. It is convenient and quick to use.

[0003] However, due to the viscosity of the double-sided tape itself and the sealing and pasting method, the packaged products may collide during transportation or during steam sterilization (especially pressure steam sterilization), whether it is pre-vacuum or pulsating vacuum, because the sterilizer will be evacuated and then steam will be injected. During this process, a large pressure difference will be generated inside and outside the ziplock bag, resulting in expansion or contraction. The expansion can easily cause the double-sided tape at the bag opening to burst, affecting its use. Summary of the invention

[0004] The utility model aims to provide a medical composite film bag, which can effectively avoid the explosion of the sealing part and improve the sealing performance of the bag mouth.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a medical composite membrane bag, comprising medical dialysis paper and a medical composite membrane body, characterized in that: the medical dialysis paper and the medical composite membrane body are connected by three edges through hot fusion to form a U-shaped cavity, the opening of the U-shaped cavity is the bag opening, the medical dialysis paper extends outward at the bag opening to form a sealing tongue, a buckle is fixedly connected to the outer wall of the medical composite membrane body and one side close to the bag opening, a fastening strip is arranged on the back of the sealing tongue, and two connecting ribs are fixedly connected between the fastening strip and the sealing tongue.

[0006] In order to facilitate the sealing tongue to be inserted into the buckle, as a preferred medical composite film bag of the utility model, the width of the buckle is equal to the width of the medical dialysis paper and the medical composite film body.

[0007] In order to facilitate the connection rib to enter the penetration port, as a preferred medical composite film bag of the utility model, the outer wall of the buckle is provided with two penetration ports, and the two penetration ports are connected to the outside of one side close to the sealing tongue.

[0008] In order to facilitate the pasting of the sealed bag mouth, as a preferred medical composite film bag of the utility model, the front end surface of the sealing tongue and the side of the fastening strip close to the sealing tongue are both provided with an adhesive layer.

[0009] In order to isolate the protective adhesive layer, as a preferred medical composite film bag of the utility model, the outer walls of the two adhesive layers are both provided with isolation paper.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] When the utility model is used, the sealing tongue is pasted and fixed to the outer wall of the medical composite membrane body, and then the fastening strip is pasted and fixed to the outer wall of the buckle, and the double fixation effectively improves the sealing strength; when the utility model expands due to the pressure difference, the buckle will be squeezed outward, and the buckle applies pressure to the outer fastening strip, and the fastening strip and the sealing tongue are connected by two connecting ribs. At this time, the fastening strip and the buckle are pulled more and more tightly under the pulling of the two connecting ribs, thereby improving the connection strength between the fastening strip and the buckle, effectively avoiding the explosion of the sealing part, and improving the sealing performance of the bag mouth.
