[0005] The purpose of this invention is to provide a medical sterilization bag with a double-sealing structure to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a medical sterilization bag with a double-sealing structure, comprising a sterilization bag; the sterilization bag consists of a bag body and a sealing tape, the sealing tape is adhered to the upper end of the bag body with adhesive, a first adhesive is provided on the upper side of the sealing tape, a bending crease is provided on the upper side of the bag body corresponding to the position below the sealing tape, a first adhesive is provided on one side of the upper end of the bag body, an outer protective film and an inner bag are provided inside the bag body, the outer protective film is attached to the outside of the inner bag, heat sealing rings are provided on both sides and the bottom of the bag body, a desiccant and a sterilization pack are placed inside the bag body, a tear is provided on one side of the upper end of the bag body, and a label is adhered to the outside of the bag body with adhesive.

[0007] Preferably, a carrying handle is provided at the upper end of the bag body, and the carrying handle is fixed to the upper side of the bag body by adhesive.

[0008] Preferably, the outer side of the bag is provided with a self-cleaning layer, which is a nano-silicon coating layer.

[0009] Preferably, the sterilization pack consists of a non-woven fabric bag and negative ion powder, with the negative ion powder filling the inside of the non-woven fabric bag.

[0010] Preferably, the desiccant package consists of a desiccant and a non-woven fabric package, with the desiccant filling the inside of the non-woven fabric package.

[0011] Preferably, a release film is disposed on the outer side of the first colloid and the second colloid, and the release film is attached to the outer side of the first colloid and the second colloid.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. First, the upper side of the bag is sealed with the second adhesive; then the sealing tape is folded along the crease on the upper side of the bag, and the first adhesive on the sealing tape will stick to the bag.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the present invention, a medical sterilization bag with a double sealing structure includes a sterilization bag 1; the sterilization bag 1 is composed of a bag body 3 and a sealing strip 7, the sealing strip 7 is pasted to the upper end of the bag body 3 with adhesive, a first adhesive 9 is provided on the upper side of the sealing strip 7, a bending line is provided on the upper side of the bag body 3 corresponding to the position below the sealing strip 7, the first adhesive 9 is provided on one side of the upper end of the bag body 3, an outer protective film 14 and an inner bag 10 are provided inside the bag body 3, the outer protective film 14 is attached to the outside of the inner bag 10, heat sealing rings 2 are provided on both sides and the bottom of the bag body 3, a desiccant 13 and a sterilization pack 12 are placed inside the bag body 3, a tear 15 is provided on one side of the upper end of the bag body 3, and a label 4 is pasted to the outside of the bag body 3 with adhesive.

[0025] A carrying handle 11 is provided at the upper end of the bag body 3. The carrying handle 11 is fixed to the upper side of the bag body 3 with adhesive. The adhesive firmly fixes the carrying handle 11 to the bag body 3. When it is necessary to move or transfer the sterilization bag 1, medical staff can easily lift the sterilization bag 1 through the carrying handle 11 to avoid direct contact with the bag body 3, reduce the risk of contamination, and make the handling process more convenient and labor-saving. A self-cleaning layer 5 is provided on the outside of the bag body 3. The self-cleaning layer 5 is a nano-silicon coating layer. The special molecular structure of the nano-silicon coating layer used in the self-cleaning layer 5 gives it strong hydrophobicity and low surface energy. When the surface of the sterilization bag 1 is contaminated with dust, stains or liquids, these substances are difficult to adhere to the surface and will slide off on their own under the action of gravity or external force, thereby realizing the self-cleaning function of the surface of the sterilization bag 1, keeping the outside of the sterilization bag 1 clean, and reducing the possibility of external contamination of the contents of the bag.

[0026] The sterilization bag 12 consists of a non-woven fabric bag and negative ion powder. The negative ion powder is filled inside the non-woven fabric bag. When the sterilization bag 12 is in use, the non-woven fabric bag has good air permeability, which allows the negative ion powder to fully contact the surrounding air. The negative ion powder releases negative ions, which can combine with the positive charge on the surface of bacteria, destroy the cell membrane structure of bacteria, interfere with the physiological metabolic process of bacteria, and prevent bacteria from surviving and reproducing normally, thereby achieving the purpose of sterilization and maintaining the sterile state inside the sterilization bag 1.

[0027] The desiccant pack 13 consists of a desiccant and a non-woven fabric pack. The desiccant is filled inside the non-woven fabric pack. When the desiccant pack 13 is in use, the non-woven fabric pack allows moisture molecules to pass through. The desiccant has strong water absorption and can absorb water vapor inside the sterilization bag 1. When the humidity inside the bag is high, the desiccant absorbs moisture, reduces the humidity inside the bag, and prevents problems such as microbial growth and rusting of metal instruments caused by dampness, thus providing a dry storage environment for the items inside the bag.

[0028] A release film 8 is provided on the outer side of the first colloid 9 and the second colloid 6. The release film 8 is attached to the outer side of the first colloid 9 and the second colloid 6. The surface of the release film 8 has a special coating with extremely low surface energy. The adhesion between the release film 8 and the first colloid 9 and the second colloid 6 is much less than the cohesive force of the first colloid 9 and the second colloid 6 themselves. This can effectively isolate the first colloid 9 and the second colloid 6 from contact with external substances, prevent the first colloid 9 and the second colloid 6 from accidentally adhering to other objects when the sterilization bag 1 is not in use, and ensure the stickiness of the first colloid 9 and the second colloid 6. When it is necessary to seal the sterilization bag 1, simply tear off the release film 8 to expose the first colloid 9 and the second colloid 6, and a firm bond can be achieved between the sealing tape 7 and the bag body 3 and between the upper end of the bag body 3.

[0029] The working principle and usage process of this utility model are as follows: When using the sterilization bag 1, the heat sealing ring 2 heats the sides and bottom of the bag body 3 to achieve a tight seal, thereby reducing the multi-layer seal between the outer protective film 14 and the inner bag 10 on both sides and bottom. After the items are placed inside the bag body 3, the upper side of the bag body 3 is first sealed by the second adhesive 6; then the sealing tape 7 is folded along the crease on the upper side of the bag body 3, and the first adhesive 9 on the sealing tape 7 will adhere to the bag body 3. The sealing tape 7 is then folded on both sides to wrap around and adhere the sides of the bag body 3, achieving a secondary seal. The double seal effectively prevents external bacteria from entering and ensures a sterile environment inside the bag. The outer protective film 14 and the inner bag 10 provide physical protection for the items and prevent external physical damage. The desiccant 13 absorbs moisture inside the bag to prevent moisture from affecting the sterilization effect and item preservation. The sterilization pack 12 releases sterilizing substances to continuously inhibit bacterial growth. The tear opening 15 facilitates quick opening of the sterilization bag 1 during use. The label 4 is used to mark the information of the items inside the bag.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
