Breathable sterilization bag structure

This creation relates to medical sterilization bags, especially a gas permeable sterilization bag structure.

Medical devices must undergo a sterilization process prior to use to ensure safe use. Moreover, the disinfection of the medical device is to put the medical device into a medical sterilization bag, seal it, and then send it into a sterilization process for disinfection. After the sterilization process is completed, the bag and the medical device can be maintained in a sterile state. status.

After the sterilization of the conventional sterilization bag, the bag of the sterilization bag needs to be torn open to take out the medical device. In particular, in the case where the opening of the bag opening after the tearing is small, it is difficult for the user to take the instrument in the sterilization bag, resulting in inconvenience in use. In addition, during the process of inserting the hand into the bag, the user may also touch the use site of the device to cause particle contamination, which may cause a risk of infection of the patient.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

One of the aims of the present invention is to provide a gas permeable sterilization bag structure, wherein the bag body can be completely peeled off from one side of the tear opening through the arrangement of the sealing structure, and the sealing structure is designed by labor saving. In combination with the material, the integrity of the bag can be maintained when the tear is opened, so that the objects in the sterilization bag can be taken out to avoid contamination of objects in the sterilization bag.

In order to achieve the above purpose, the present invention is a gas permeable sterilization bag structure comprising a bag body, a gas permeable sheet and a sealing structure. The bag body has an accommodating space, a tearing opening on one side of the accommodating space, and an engaging opening that communicates with the accommodating space; the gas permeable sheet is coupled to the bag body corresponding to the joint opening; the sealing structure is disposed on the bag body and sealed One side of the accommodating space, the sealing structure comprises at least one peeling edge adjacent to the tearing opening and contacting, and the width of the at least one peeling edge across the bag body is equal to the width of the tearing opening.

Another object of the present invention is to provide a gas permeable sterilization bag structure, wherein the bag system is composed of an easily peelable or flexible substrate, and the breathable film is composed of a gas permeable substrate, thereby achieving a full open type of the bag body. Peelability and gas permeability.

Another object of the present invention is to provide a gas permeable sterilization bag structure which is provided with a plurality of heat sealing zones on both sides of the tear opening to prevent peeling due to inadvertent pulling and tearing at the peeling edge, and can maintain the Tear the flatness of the opening.

Compared with the prior art, the breathable sterilization bag structure of the present invention is provided with a sealing structure on the bag body, the sealing structure comprising at least one peeling edge adjacent to the tear opening, and at least one peeling edge spanning the bag body The width is equal to the width of the tearing opening, according to which, when the side of the tearing opening is applied, the bag body can be completely opened by one side of the tearing opening due to the arrangement of the sealing structure, so as to directly expose the waiting Sterilizing objects. Thereby, it is advantageous to tear the bag body structure out, that is, to take out the object in the bag (one-time tearing away), instead of taking the object after tearing (two-stage tearing off). Accordingly, the risk of infection can be prevented from being touched during the removal of the object in the bag, thereby avoiding contamination of objects in the sterilization bag; in addition, the bag system of the present invention is composed of an easily peelable or flexible substrate. The gas permeable sheet is composed of a gas permeable substrate, and the material can facilitate the easy peeling of the bag body and increase the practicality of the creation.
