Description

Synthetic resin transparent bag for sterilizing Iogas sterilization of medical equipment and its manufacturing method {TRANSPARENT PLASTIC ENVELOPES FOR STERILIZING THE MEDICAL DEVICES USING EO GAS AND METHOD FOR PREPARING THEM}

The present invention relates to a synthetic resin transparent bag used for sterilizing sterilization of EO gas of medical instruments, especially syringes. Medical devices such as syringes are put in a packaging bag and sterilized with IOS gas. An envelope for packaging a medical device is an envelope having one side wall formed of paper and the other side wall made of a transparent film so that the contents of the medical device can be seen from the outside. The envelope in which the whole side wall of an envelope is formed from the transparent film is used.

The sterilization method using IOS gas is composed of IOS gas permeable paper on one side, and the other side wall is made of transparent synthetic resin film, inserting medical instruments therein, and then bonding the paper plate and IOS gas impermeable synthetic resin sheet and In the high-pressure chamber containing the pressure gas, the gas is introduced into the bag through the fine pores between the fibers constituting the paper having the gas permeability, and then the air is discharged and sterilized.

This sterilization method consists of inserting paper and plastic film medical instruments, then bonding the paper and plastic films at the four peripheries of the medical instruments and sterilizing them in an Iogas pressure chamber filled with ion gas. While there is an advantage that the four peripheral edges of the adhesive can be bonded at the same time, the adhesive state is separated because the adhesion state of the heterogeneous paper and the resin film is not properly made. In addition, medical device packaging bags are formed of paper and resin film, so problems appear in the separate collection after use. In particular, the envelope formed of paper and plastic film is a phenomenon that the consumer avoids use because the paper part is damaged when storing or transporting medical instruments.

Another method of sterilization using IOS gas is a transparent synthetic resin film composed of IOS gas impermeable transparent synthetic resin with upper, lower, left and right sidewalls. It was then composed of a method of sterilizing inside the IOS gas sterilizer and taking it out of the sterilizer to seal the open end by a separate bonding process.

In this method, the front side of the bag is made of transparent synthetic resin film, so there is no adhesion failure, no problem of collecting and removing paper, and there is little risk of damage because paper is not used, while one end is opened in the IOS gas pressure chamber. After opening and sterilizing, the opened end should be removed from the IOS gas pressure chamber and bonded in a separate bonding process. Therefore, the bag forming and sealing are carried out in a separate process, resulting in a rise in labor costs in the manufacturing process. Work is inconvenient because it does not end with 2 steps.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sterile bag for a medical device that can solve the problems of the above-described conventional method in which the entire bag is made of transparent synthetic resin and can be manufactured in a single process.

The above object of the present invention is to create an unpenetrated scratch having a permeability of about 20,000 to 30,000 cc / 24h of the film so that foreign matter such as bacteria does not penetrate through the ion gas through the transparent film constituting the side wall of the bag. A plastic bag for sterilizing and disinfecting medical devices is achieved.

The envelope of the present invention is manufactured in a form in which a cover film is attached to an upper surface of a bottom film having a groove into which a medical device is inserted. It is preferable that both the bottom film and the cover film are formed of a polypropylene film, and the bottom film has a thickness of 40 to 100 microns and the cover film is preferably formed of a film having a thickness of 20 to 50 microns. .

In the bag for sterilizing the ion gas of the medical apparatus according to the present invention, fine scratches were formed on one of the bottom film and the cover film constituting the bag.

The minute scratches formed on the envelope according to the present invention may be formed only on one side wall or both side walls of both side walls constituting the envelope.

Fine scratches according to the present invention are minute enough to be invisible to the naked eye. Scratches as described above allow Io gas to pass but keep moisture and other dirt out.

Referring to the bag manufacturing method using the film in the bag for syringe packaging as follows.

The bottom film and the cover film used in the present invention are formed of a transparent synthetic resin, for example, polypropylene resin. The bottom film has a thickness of 40 to 100 microns and the cover film has a thickness of 20 to 50 microns.

The method of the present invention comprises the steps of forming a groove for inserting a medical device in the bottom film, inserting a syringe inside the groove, covering the cover film processed with scratches on the bottom film in which the syringe is inserted, and four peripheral top surfaces of the bottom film. Welding the bottom film and the cover film by heating and pressing, inserting the bag with the medical device inserted therein and covering the cover film in the IOS gas sterilizer, injecting the IOS gas into the bag, and the IOS gas-infused bag. Consists of a method for producing a bag for sterilizing the ion gas of the medical device comprising the step of discharging the ion gas from.

In the method of the present invention, the groove for inserting the medical device of the bottom film has a mold having a groove sized to be inserted into the syringe to move along the conveyor and to supply the bottom film supplied from the bottom film roll. The top film is formed by pressing or vacuuming the bottom film of the groove portion with the top mold covered thereon.

The step of inserting a medical device is a step of inserting a medical device into the groove portion of the bottom film which has been subjected to the groove forming process. In general, a medical device can be directly inserted by a person, but if necessary, an automatic system is automatically used. The medical device may be inserted into the groove.

Covering the cover film on the bottom film is a step of covering the cover film on the bottom film obtained through the medical instrument insertion step, in which the cover film supplied from the cover film roll is placed on the bottom film.

The step of welding by pressing the four peripheral upper surface of the bottom film by welding, the step of making a sealing bag in which the medical device is inserted by heating and pressing the four peripheral parts of the bottom film, by installing a pressing die heated from the four peripheral upper surface of the bottom film As the pressing die is lowered, the cover film is heated and compressed to compress the bottom film and the cover film.

The sterilization step of the IOS gas is a step of inserting a sealed bag with a medical device into the IOS gas pressure chamber so that the IOS gas is injected into the sealed bag and sterilized. Drain the dragon gas. After this process, a unit of sterile transparent sealing bag is obtained.

According to the present invention, a packaging bag for a medical device composed of a transparent synthetic resin bottom film and a transparent synthetic resin cover film can be injected and discharged with ion gas after adhering four peripheral portions of the bag in a state where the medical device is contained. In the bag composed of a synthetic resin, since the open end is opened, the sterilization process can be omitted by injecting sterilized by injecting gas, and the bag is taken out and sealed, thereby facilitating sterilization and packaging of the medical device.
