Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouch structure for sterilizing a medical instrument,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouch structure for packaging a medical instrument of a sterilizer used in a sterilizer for sterilizing a medical instrument such as a surgical tool at a high temperature.

In general, medical instruments such as scalpels or scissors are sterilized at a high temperature of 140 to 190 ° C for 3 to 250 minutes through a sealed dry sterilizer without packaging, and sterilized The medical device is taken out of the dry heat sterilizer and used for surgery.

As described above, the effect of sterilizing the surgical instrument through the dry heat sterilizer is in the region, but when the closed door is opened to draw the sterilized surgical instrument from the high pressure steam sterilizer, the outside air is drawn into the dry heat sterilizer, The sterilizing effect is extremely reduced due to pathogens contained in the air, and particularly, when the exposed surgical instruments are moved in the air, the surgical instruments may be contaminated with the pathogens contained in the air, thereby causing a problem of extreme sterilization.

In order to solve such a problem, it is preferable to sterilize the surgical instrument to be sterilized in a dry sterilizer by wrapping it in a packaging material capable of withstanding high temperatures. However, in this case, it is troublesome to wrap the surgical tool with the packaging material, The sterilizing effect can not be increased, and the sterilized packaging film must be cut with a separate tool to draw out the sterilized surgical tool, and thus the surgical tool is again contaminated by pathogens in the air during withdrawal .

In order to solve such a problem of the packaging film, a medical packaging roll obtained through a manufacturing apparatus of Korean Patent No. 10-1396568 can be used. In this case, the packaging roll is made of a synthetic resin film (e.g., polyurethane resin) , The edges of the two synthetic resin films are thermally fused to form an envelope to sterilize the surgical instrument with high temperature heat by putting a medical instrument in the envelope. When used in a dry heat sterilizer sterilized at a high temperature of 140 to 190 ° C, In severe cases, the synthetic resin in the form of envelope sticks strongly to the surgical tool, which makes it difficult to separate the synthetic resin and the surgical tool from each other. In the separation operation, there is a defect that contaminates the surgical tool, The problem is pointed out.

The two edges of the prepared laminated film are thermally fused (heat-sealed) at 160 to 200 ° C, Which is used in a high-temperature environment for sterilization of medical instruments.

The open part of the obtained pouch is sealed with a heat-resistant adhesive tape (for example, silicone, capton tape, PET or the like), or the laminated film of the open part and the laminated film are thermally fused at 160 to 200 ° C .

The present invention relates to a heat-resistant polyester film and a heat-resistant adhesive such as a polyurethane-based nylon which are excellent in heat resistance and adhesion, and can withstand a high temperature of 140 to 190 ° C without being damaged or damaged. It is suitable for the application of pouches used for sterilization by packing medical instruments including surgical instruments inside a dry heat sterilizer which is sterilized at a high temperature of 140 ~ 190 ℃ for 3 ~ 250 minutes through a sealed dry heat sterilizer, If a single film is provided with a film which is not damaged or broken at a high temperature of 140 to 190 DEG C, it causes a very high cost increase. However, the present invention can be achieved by bonding an inexpensive polyester (PET) film and nylon It is possible to provide a pouch using a formed piece of film, thereby reducing manufacturing costs.
