Description
Technical Field
The utility model relates to the field of sterilization packaging, in particular to a medical packaging bag suitable for multiple sterilization modes.
Background
In medical sterilization packaging, common sterilization methods include pressure steam sterilization, Ethylene Oxide (EO) sterilization, formaldehyde steam (formalin) sterilization, radiation sterilization, and hydrogen peroxide plasma sterilization. These sterilization methods are different in their own characteristics and require different performance from the sterilized packaging materials. For example: in the common sterilization modes, except for the material for packaging by radiation sterilization, the ventilation is not needed, and other sterilization modes all need ventilation materials to facilitate the entering and exiting of sterilization factors; the radiation sterilization has great damage to the polypropylene material, and the polymer molecular chain is broken under the impact of high energy to cause the material to be embrittled; but polypropylene (PP) material is a better choice for pressure steam sterilization packaging; polyethylene (PE) materials can be suitable for radiation sterilization, but cannot withstand the high temperatures of pressurized steam; the gas-permeable material for hydrogen peroxide plasma sterilization cannot adopt biological fiber and the like.
Therefore, medical packaging bags which can be simultaneously suitable for more than three common sterilization modes in the market are almost difficult to find. The packaging box can be suitable for packaging in various sterilization modes, is more convenient for customers to use, and greatly reduces the inventory of different sterilization mode packages required by the customers.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a medical packaging bag suitable for multiple sterilization modes, so that the problem that the medical packaging bag suitable for more than three sterilization modes simultaneously is lacked in the prior art is solved.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a be suitable for medical wrapping bag of multiple sterilization mode, medical wrapping bag is scalded through three-sided sealing by first sheet and second sheet and is formed, does not seal the part formation sack that scalds the connection, with the part that the sack is relative is at the bottom of the bag, first sheet is the non-woven fabrics, the second sheet is PET/easily take off the PP complex film, the printing has pressure steam sterilization sign, ethylene oxide sterilization sign, formaldehyde steam sterilization sign and hydrogen peroxide plasma sterilization sign on the bag body of medical wrapping bag.
Preferably, the PET/easy-to-tear PP composite film is formed by compounding a PET film with the thickness of 12 microns and an easy-to-tear PP film with the thickness of 40-60 microns.
Preferably, the non-woven fabric is made of polypropylene.
Preferably, the gram weight of the non-woven fabric is 60 to 90 grams per square meter.
Preferably, the pressure steam sterilization indicator, the ethylene oxide sterilization indicator, the formaldehyde steam sterilization indicator and the hydrogen peroxide plasma sterilization indicator are printed on the inner surface of the non-woven fabric facing the PET/easy-to-tear PP composite film.
Preferably, the bag bottom is V-shaped.
According to the medical packaging bag applicable to various sterilization modes, compared with the prior art, the medical packaging bag has the following beneficial effects:
1) the air-permeable material of the packaging bag is made of special non-woven fabric material, so that the air permeability is excellent, and the risk of sterilization failure caused by bag explosion due to insufficient air permeability during pressure steam sterilization is avoided; during ethylene oxide sterilization, the sterilization medium can enter conveniently, and the ethylene oxide after sterilization can be analyzed, so that the risk of the excessive residual ethylene oxide is greatly reduced;
2) the plastic film of the packaging bag adopts a PET/easy-to-tear PP composite film with high temperature resistance, not only can bear pressure steam sterilization, but also has high peeling strength after being sealed and ironed with special non-woven fabric, good peeling effect and no fiber scraps, and reduces the risk of secondary pollution to medical instruments or articles when being peeled and opened;
3) the non-woven fabric material has good air permeability and strong microbial barrier performance, while the PET/easy-to-tear PP composite film is an airtight material, so that the microbial barrier performance is better, and the composite film is a transparent material, therefore, the packaging bag formed by combining the non-woven fabric and the polypropylene easy-to-tear peelable composite film has good bacteria resistance and higher safety, and meanwhile, the articles in the packaging bag can be conveniently checked;
4) the sterilization applicability is strong, the sterilization can be applicable to sterilization in various sterilization modes, multiple purposes are really realized, the inventory cost is reduced, and the storage site is saved;
5) the breathable material non-woven fabric is printed with a pressure steam sterilization indicator, an ethylene oxide sterilization indicator, a formaldehyde steam sterilization indicator and a hydrogen peroxide plasma sterilization indicator, after any one of the sterilization modes is subjected to sterilization treatment, the color of the corresponding sterilization indicator can change, whether the package is subjected to sterilization treatment or not can be judged according to the color change of the sterilization indicator, and the sterilized article can be protected.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that the following examples are illustrative only and are not intended to limit the scope of the present invention.
Referring to fig. 1 and 2, a medical packaging bag according to a preferred embodiment of the present invention is formed by connecting a first sheet and a second sheet by three-edge sealing, wherein the portion that is not sealed and connected forms a bag opening 2, the portion opposite to the bag opening 2 is a bag bottom 1, the sealing and connecting portion is shown as 5, the first sheet is a non-woven fabric 3, the second sheet is a PET/easy-to-tear PP composite film 4, and a pressure steam sterilization indicator 61, an ethylene oxide sterilization indicator 62, a formaldehyde steam sterilization indicator 63, and a hydrogen peroxide plasma sterilization indicator 64 are printed on the inner surface of the non-woven fabric 3.
According to the preferred embodiment, the nonwoven fabric 3 is made of polypropylene, is available under the trade name DuraMed (www.berryplastics.com) from pure nonwoven fabric (china), has good air permeability, tensile strength and tear strength, has good microbial barrier properties, and is suitable for pressure steam sterilization, ethylene oxide sterilization, formaldehyde steam sterilization, hydrogen peroxide plasma sterilization, and the like, and has a handling property in bag making that cannot be achieved by ordinary nonwoven fabrics. Compared with the common non-woven fabric, the non-woven fabric has the advantages of good stiffness, compact texture and good bacterium resistance.
According to the preferred embodiment, the PET/easy-to-tear PP composite film 4 is formed by compounding a PET film with the thickness of 12 microns and an easy-to-tear PP film with the thickness of 40-60 microns, the trade name of the PET/easy-to-tear PP composite film is the PET/easy-to-tear PP composite film, and the PET/easy-to-tear PP composite film is purchased from Henan institute medical equipment packaging Limited company.
