Description

Technical Field

[0001] This utility model relates to the technical field of medical packaging, and in particular to an oxidation color-changing aging device for the opening of a medical cotton swab packaging. Background Technology

[0002] In clinical medical practice, medical cotton swabs are indispensable medical supplies, widely used for wound disinfection, sampling, and other procedures. According to medical disinfection and isolation guidelines, medical cotton swabs must be used within 4 hours of opening the package to meet safety standards. Beyond this time, the risk of bacterial contamination increases dramatically, and continued use can easily lead to adverse consequences such as wound infection in patients, seriously affecting medical quality and patient safety.

[0003] However, current medical cotton swab packaging lacks effective means of indicating the expiration time after opening. Medical staff, busy with their work, find it difficult to constantly monitor when the swabs have been opened, often resulting in unused swabs being used even four hours after opening. Existing packaging, relying solely on production date and expiration date markings, cannot meet the monitoring needs for post-opening expiration time, leading to the misuse of large quantities of expired swabs and posing a significant threat to medical safety. This problem urgently needs to be solved; developing a device that starts timing immediately upon opening the cotton swab packaging and provides a visual color-changing indication after four hours is urgently needed to ensure the standardization and safety of medical procedures. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose an oxidation color-changing aging device for the opening of medical cotton swab packaging. Through structural design and the application of color-changing materials, it can intuitively indicate the usage time of medical cotton swabs after opening, observe the color of the color-changing material layer to determine whether the cotton swab is within its expiration date, avoid using expired cotton swabs, reduce the risk of medical infection, ensure the stability of the color-changing material layer through a transparent protective layer, and make the packaging easy to open by the coordinated design of each component, thereby improving the efficiency of medical work.

[0006] To achieve the above objectives, this utility model proposes an oxidation-discoloration aging device for the opening of a medical cotton swab packaging, comprising a cotton swab packaging bag, a color-changing material layer, a transparent protective layer, an opening device, and a tear-off opening. The color-changing material layer is disposed below the opening of the cotton swab packaging bag and is composed of a coating containing a chemical indicator. When not exposed to air, it exhibits an initial color, and after 4 hours of oxidation upon exposure to air, it gradually transforms into a warning color. Its thickness is 0.1-0.3 mm. The transparent protective layer covers the outside of the color-changing material layer and is made of medical-grade transparent plastic film with a thickness of 0.05-0.1 mm. The opening device is located at the opening of the cotton swab packaging bag, and the tear-off opening is connected to the opening device. A connector is provided between the tear-off opening and the transparent protective layer. When the tear-off opening is pulled, it causes the opening device to separate from the cotton swab packaging bag, and simultaneously the connector tears the transparent protective layer, exposing the color-changing material layer to air and initiating oxidation and discoloration.

[0007] This utility model discloses an oxidation color-changing aging device for the opening of medical cotton swab packaging. Through structural design and the application of color-changing materials, it provides a direct indication of the expiration time of medical cotton swabs after opening. By observing the color of the color-changing material layer, it can determine whether the cotton swab is within its expiration date, avoid using expired cotton swabs, reduce the risk of medical infection, ensure the stability of the color-changing material layer through a transparent protective layer, and make the packaging easy to open by the coordinated design of each component, thus improving the efficiency of medical work.

[0008] In addition, the oxidation color-changing aging device for the opening of a medical cotton swab packaging as proposed above may also have the following additional technical features:

[0009] Specifically, the color-changing material layer achieves color change based on an oxidation-reduction reaction, with the initial color being light blue and the warning color being red.

[0010] Specifically, the connector is an easy-tear connection structure, including but not limited to easy-tear lines and easy-tear adhesive strips.

[0011] Specifically, the opening device is integrally formed with the cotton swab packaging bag, the opening device is connected to the main body of the cotton swab packaging bag through a weakening line, and the tear opening is located at the end of the opening device away from the weakening line.

[0012] Specifically, the edge of the transparent protective layer is sealed to the cotton swab packaging bag. When the connector is not pulled, the transparent protective layer completely covers the color-changing material layer, preventing the color-changing material layer from contacting the air.

[0013] The advantages of this invention compared to existing technologies are as follows:

[0014] (1) Through structural design and the application of color-changing materials, the effective use time of medical swabs after opening is intuitively indicated. Medical staff can quickly determine whether the swabs are within the effective use time by observing the color of the color-changing material layer, which effectively avoids the use of expired swabs, strictly follows the disinfection and isolation standards, and greatly reduces the risk of medical infection.

[0015] (2) The transparent protective layer protects the stability of the color-changing material layer. The coordinated design of the opening device, tear-out and connector makes the packaging easy to open and convenient to operate, which is in line with the usage habits of clinical medical staff and improves the efficiency of medical work.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which:

[0021] As shown in the figure: 1. Cotton swab packaging bag; 2. Color-changing material layer; 3. Transparent protective layer; 4. Opening device; 5. Tear opening; 6. Connector. Detailed Implementation

[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0023] The following description, in conjunction with the accompanying drawings, describes an oxidation and color-changing aging device for the opening of a medical cotton swab packaging according to an embodiment of the present invention.

[0024] like Figures 1-3As shown in the figure, an oxidative color-changing aging device for the opening of a medical cotton swab packaging according to an embodiment of the present invention includes a cotton swab packaging bag 1, a color-changing material layer 2, a transparent protective layer 3, an opening device 4, and a tear-off opening 5.

[0025] It is understandable that when medical staff are ready to use the cotton swabs, they will operate the tear strip 5. The tear strip 5 is connected to the opening device 4. During the process of pulling the tear strip 5, the opening device 4 will separate from the cotton swab packaging bag 1 along with the movement of the tear strip 5. Because the opening device 4 is located at the opening of the cotton swab packaging bag 1, and through certain designs (such as being integrally formed with the packaging bag and having a weakening line), this separation operation is convenient and reasonable.

[0026] Meanwhile, the connector 6 between the tear-off opening 5 and the transparent protective layer 3 plays its role. The connector 6 is an easy-tear connection structure, such as an easy-tear line or easy-tear adhesive strip. When the tear-off opening 5 is pulled, the connector 6 will cause the transparent protective layer 3 to tear open. The transparent protective layer 3 is made of medical-grade transparent plastic film with a thickness of 0.05-0.1mm. It originally covers the outside of the color-changing material layer 2, and its function is to protect the color-changing material layer 2 from external factors when it is unopened. After being torn open, it allows the color-changing material layer 2 to be exposed to the air.

[0027] A color-changing material layer 2 is located below the opening of the cotton swab packaging bag 1. It consists of a coating containing a chemical indicator and has a thickness of 0.1-0.3 mm. When not exposed to air, it displays its initial color. Once exposed to air, it begins an oxidation reaction over 4 hours, gradually changing to a warning color. This allows medical personnel to visually determine whether the cotton swab is still within its effective usage period simply by observing the color of the color-changing material layer 2, thus avoiding the use of expired cotton swabs and ensuring medical safety.

[0028] In one embodiment of this utility model, such as Figures 1-3 As shown, the color-changing material layer 2 achieves color change based on a redox reaction, with an initial color of light blue and a warning color of red.

[0029] Understandably, when the medical cotton swab packaging is unopened, the color-changing material layer 2 is sealed under the transparent protective layer 3, isolating it from the outside air, and at this time it appears as an initial light blue color. The transparent protective layer 3 is made of medical-grade transparent plastic film with a thickness of 0.05-0.1mm. It not only protects the color-changing material layer 2 from external factors such as friction and moisture, but also ensures that medical staff can clearly see the color of the color-changing material layer 2.

[0030] When medical staff need to use cotton swabs, they pull the tear strip 5. The tear strip 5 is connected to the opening device 4. Pulling the tear strip 5 will cause the opening device 4 to separate from the cotton swab packaging bag 1. At the same time, the connector 6 between the tear strip 5 and the transparent protective layer 3 is pulled, causing the transparent protective layer 3 to tear open, and the color-changing material layer 2 is exposed to the air.

[0031] Oxygen in the air acts as an oxidant, reacting with the chemical indicator in the color-changing material layer 2 in a redox reaction. Over the next four hours, as the redox reaction continues, the color of the color-changing material layer 2 gradually changes from light blue to red. When medical staff observe that the color-changing material layer 2 has turned red, it indicates that four hours have passed since the packaging was opened and the color-changing material layer 2 came into contact with air. At this point, the swab has exceeded its effective usage time and should no longer be used. This color-changing design based on a redox reaction, using light blue as the initial normal indicator color and red as the warning color, provides a clear and easily observable color change, helping medical staff accurately determine the expiration date of the swab and effectively ensuring the safety of medical procedures.

[0032] In one embodiment of this utility model, such as Figures 1-3 As shown, connector 6 is an easy-tear connection structure, including but not limited to easy-tear lines and easy-tear adhesive strips.

[0033] It is understandable that during the packaging production stage, a suitable easy-tear connection structure will be selected as the connector 6 according to actual needs, such as an easy-tear line or an easy-tear adhesive strip. If an easy-tear line is used, an easy-to-tear line will be pressed into a suitable position between the tear opening 5 and the transparent protective layer 3 through a specific process to form the easy-tear line connector 6; if an easy-tear adhesive strip is used, an adhesive strip with easy-tear properties will be pasted between the tear opening 5 and the transparent protective layer 3.

[0034] In one embodiment of this utility model, such as Figures 1-3 As shown, the opening device 4 is integrally formed with the cotton swab packaging bag 1. The opening device 4 is connected to the main body of the cotton swab packaging bag 1 through a weakening line, and the tear opening 5 is located at the end of the opening device 4 away from the weakening line.

[0035] It is understandable that, during the production process, the opening device 4 and the cotton swab packaging bag 1 are manufactured using an integrated molding process. This method ensures the integrity and stability of the opening device 4 and the cotton swab packaging bag 1. Simultaneously, a weakening line is provided at the connection point between the opening device 4 and the main body of the cotton swab packaging bag 1. The presence of the weakening line reduces the connection strength between the opening device 4 and the main body of the cotton swab packaging bag 1, but still ensures that the two remain connected when no external force is applied, guaranteeing the airtightness of the packaging.

[0036] In one embodiment of this utility model, such as Figures 1-3As shown, the edge of the transparent protective layer 3 is sealed to the cotton swab packaging bag 1. When the connector 6 is not pulled, the transparent protective layer 3 completely covers the color-changing material layer 2, preventing the color-changing material layer 2 from contacting the air.

[0037] It is understandable that during the production stage, when the transparent protective layer 3 is made, its edges are sealed to the cotton swab packaging bag 1. The sealing method can employ heat sealing, adhesive sealing, or other processes to ensure a seamless connection, preventing the entry of external air, moisture, and impurities. After the sealing is completed, the transparent protective layer 3 completely covers the color-changing material layer 2. The color-changing material layer 2, located below the opening of the cotton swab packaging bag 1, is composed of a coating containing a chemical indicator and displays its initial color when not exposed to air. At this point, the transparent protective layer 3 acts as a barrier, isolating the color-changing material layer 2 from the external environment and preventing premature oxidation. This ensures that the color-changing material layer 2 maintains its initial state when the cotton swab packaging is unopened.

[0038] This design ensures that the color-changing material layer 2 is not affected by the outside air when the packaging is unopened. Only after the packaging is opened and the transparent protective layer 3 is torn off will the color-changing material layer 2 come into contact with the air and begin to change color, providing medical staff with a reliable basis for judging the expiration time of cotton swabs after opening.

[0039] It should be noted that the color-changing material layer 2 described in this embodiment is composed of a coating containing a chemical indicator. This chemical indicator is typically a substance with redox response properties, such as certain metal ion complexes or organic compounds. Taking a common iron-based chemical indicator as an example, it exists in a stable state in the coating. When not exposed to air, due to the lack of an oxidant (oxygen in the air), the chemical indicator is in a reduced state, causing the color-changing material layer 2 to exhibit its initial color, which is set to pale blue in this device.

[0040] When the color-changing material layer 2 comes into contact with air, the oxygen in the air acts as a strong oxidant, reacting with the chemical indicator in a redox reaction. During this process, the molecular structure of the chemical indicator changes, and the electron cloud distribution also changes, leading to a change in its light absorption and reflection characteristics, which macroscopically manifests as a change in color.

[0041] To achieve the precise color-changing function within 4 hours, the concentration of chemical indicators, reaction accelerators, and other additives in the paint formulation are carefully controlled during the design process. For example, by adjusting the concentration of the chemical indicator, the rate of its reaction with oxygen can be controlled. If the concentration is too high, the reaction may be too fast, resulting in color change in less than 4 hours; if the concentration is too low, the reaction will be too slow, taking more than 4 hours to change color.

[0042] Specifically, in actual practice, when medical staff are about to use the medical cotton swabs, they will first grasp the tear opening 5 with their hands. Since the tear opening 5 is connected to the opening device 4, and the opening device 4 is integrally formed with the cotton swab packaging bag 1 and connected by a weakening line, as the tear opening 5 is pulled, the opening device 4 is subjected to a pulling force and separates from the cotton swab packaging bag 1 along the weakening line, thereby opening the packaging opening.

[0043] As the tear strip 5 is pulled, the connector 6 between the tear strip 5 and the transparent protective layer 3 is also pulled. Under the pulling force, the material structure at the tear line is damaged and torn, ultimately causing the transparent protective layer 3 to tear. The transparent protective layer 3 originally covered the outside of the color-changing material layer 2. It is made of medical-grade transparent plastic film with a thickness of 0.05-0.1mm, and can protect the color-changing material layer 2 from external factors before it is torn.

[0044] When the transparent protective layer 3 is torn open, the color-changing material layer 2 located below the opening of the cotton swab packaging bag 1 is exposed to the air. The color-changing material layer 2 is composed of a coating containing a chemical indicator (such as an iron-based chemical indicator) and has a thickness of 0.1-0.3 mm. Before contact with air, the color-changing material layer 2 is initially pale blue. After contact with air, the oxygen in the air undergoes a redox reaction with the chemical indicator.

[0045] Over the next four hours, as the redox reaction continues, the color of the color-changing material layer 2 gradually changes from light blue to red. Medical staff can observe the color of the color-changing material layer 2 at any time during the use of the cotton swab. When the color-changing material layer 2 turns red, it indicates that four hours have passed since the packaging was opened and the color-changing material layer 2 was exposed to air. At this point, the cotton swab has exceeded its effective usage time and should not be used, thus ensuring the safety of medical procedures.

[0046] In summary, the oxidation color-changing aging device for the opening of a medical cotton swab packaging according to this utility model, through structural design and application of color-changing materials, provides a direct indication of the expiration date of the medical cotton swab after opening. By observing the color of the color-changing material layer, it is possible to determine whether the cotton swab is within its expiration date, avoid using expired cotton swabs, reduce the risk of medical infection, ensure the stability of the color-changing material layer through a transparent protective layer, and make the packaging easy to open through the collaborative design of each component, thereby improving the efficiency of medical work.
