[0021] The following will clearly and completely describe the technical solution of the utility model in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1-3 , a medical device packaging bag, a packaging bag body 100: a square or rectangular packaging bag body 100 is designed, and a material suitable for medical device packaging is used, such as durable, clean, and easy-to-sterilize plastic or cloth (such as non-woven fabric).
[0023] Design of the supporting member 110: A supporting member 110 is designed on the inner side of the bottom of the packaging bag body 100, and the supporting member is fixed to the bottom of the packaging bag body 100 by means including but not limited to heat pressing or sewing.
[0024] Three-section structure: Two longitudinal folds are arranged on the support member 110, dividing the support member 110 into three parts: two side sections and a middle section. The side sections correspond to the front and rear sides of the packaging bag body 100, and the middle section corresponds to the inner bottom of the packaging bag body 100.
[0025] Installation of the legs 120: Four legs 120 are installed at the four corners of the bottom of the support member 110. The legs 120 include but are not limited to metal or plastic materials, and are designed to be retractable to adapt to different ground conditions, or fixed to provide stable support.
[0026] The support leg 120 is not flush with the edge of the packaging bag body 100, but is retracted inward by a certain distance to ensure that the bottom end of the support leg 120 forms the vertex of a triangle, thereby enhancing the structural stability.
[0027] Construction of virtual vertex 130: The virtual vertex 130 is not a physical structure, but a concept set to describe the geometric relationship between the support leg 120 and the bottom edge of the packaging bag body 100. The position of the virtual vertex 130 is determined through design considerations in the middle of the four side lines of the bottom of the packaging bag body 100. The position of the virtual vertex 130 is the point where the extension line of the support leg 120 and the bottom edge of the packaging bag body 100 intersect. In actual production, these virtual vertices 130 can be indicated by marking or reserving folds on the material. The virtual vertex 130 is connected to the upper end of the support leg 120 to form four triangular support structures 140, each of which is composed of a support leg 120 and the corresponding two sides of the packaging bag body 100.
[0028] Function of the triangular support structure 140: The triangle is one of the most stable geometric shapes known in mechanics. In the design of the packaging bag, the triangular support structure 140 formed by the support leg 120, the bottom edge of the packaging bag body 100, and the virtual vertex 130 utilizes the stability principle of the triangle. When the packaging bag is placed on the ground or other supporting surfaces, the bottom end of the support leg 120 contacts the ground, and the virtual vertex 130 forms a closed triangle with the upper end of the support leg 120 and the edge of the packaging bag body 100 visually or physically. When the packaging bag is loaded with medical devices and placed on the ground or other supporting surfaces, the support leg 120 transfers the weight of the items in the bag to the ground. The triangular structure formed by the support leg 120 can disperse the concentrated force to a larger area, reducing the pressure on the packaging bag material. Since the triangular support structure 140 formed by the support leg 120 provides a wide support base, it can effectively resist tilting and tipping even on uneven ground or under certain external forces, protecting the safety of the internal medical devices. This triangular structure utilizes the inherent stability of a triangle. When an item is placed in the packaging bag, the weight is transferred to the supporting member 110 through the packaging bag body and then distributed to the four legs 120, thereby providing uniform support.
[0029] Through the above design, a medical device packaging bag with a stable structure is realized, which can effectively disperse the weight of the internal items, reduce the stress of the packaging bag body material, and extend the service life. The triangular support structure 140 formed by the support feet 120 and the virtual apex 130 enhances the anti-tilting and anti-overturning capabilities of the packaging bag, and remains stable even when loaded with heavy objects or placed on uneven ground. By reducing the risk of overturning, the medical devices in the packaging bag are better protected, and the risk of damage to the medical devices due to overturning of the packaging bag is reduced.
[0030] In some embodiments, a sealing member 150 is disposed on one of the long sides of the top of the packaging bag body 100 .
[0031] The main function of the seal 150 is to provide a sealing mechanism for the packaging bag 100 to ensure that the medical device remains sterile during storage and transportation. This is critical for the safe use of medical devices, as they often need to be used under sterile conditions to avoid the risk of infection. In addition to maintaining sterility, the seal 150 can also prevent dust, liquids or other contaminants from entering the interior of the packaging bag, thereby protecting the medical device from damage.
[0032] In some embodiments, two sides of the sealing member 150 are parallel to the long sides of the packaging bag body 100 .
[0033] The seal 150 is made of the same material as the packaging bag body 100, including but not limited to plastic or cloth. The seal 150 is arranged parallel to the long side of the packaging bag body 100, which can provide a continuous sealing effect. This means that from one end to the other, the seal 150 can form a straight line to ensure the sealing of the entire long side. When the seal 150 is pulled or stressed, since it is parallel to the long side of the packaging bag body 100, the force can be more evenly distributed to the entire sealing area, reducing the risk of local damage.
[0034] In some embodiments, an adhesive coating 160 is disposed on the sealing member 150 .
[0035] The main function of the adhesive coating 160 is to provide a sealing effect. When the seal 150 is pressed or closed, the adhesive coating 160 can adhere to the corresponding part of the packaging bag body 100 to form a closed packaging environment. A well-designed adhesive coating 160 should ensure that the user can easily open and close the packaging bag, while ensuring that sufficient adhesion is provided in the closed state to maintain the seal.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
