[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: See also Figure 1-Figure 6 , a color-changing consumables management indicator card, comprising a card body 1, such as Figure 2 As shown, an inner cavity is formed inside the card body 1, the inner cavity is pre-evacuated, and a water-proof and air-permeable transparent container 2 is arranged inside the card body 1, and a ferrous ion solution is contained inside; In the present invention, the transparent container 2 is made of polyethylene, polypropylene or polytetrafluoroethylene, which is water-proof and breathable, allowing oxygen to pass through, thereby causing an oxidation reaction in the ferrous ion solution. At the same time, these materials also have good transparency, chemical corrosion resistance and air permeability, ensuring that the transparent container 2 can maintain stable performance during long-term use.

[0020] like Figure 2 As shown, a gas cylinder 8 is fixedly installed in the inner cavity, and a plunger 9 is movably arranged inside the gas cylinder 8 up and down. The plunger 9 is used to transport the oxygen in the gas cylinder 8 to the inner cavity. After the oxygen is transported to the inner cavity, the ferrous ion solution changes from green to yellow through an oxidation reaction, which can intuitively display whether the medical consumables are expired, thereby avoiding the information lag problem of traditional label marking or electronic recording methods, and improving the accuracy and efficiency of validity period management. Specifically, when the ferrous ion solution appears green, it indicates that the consumables are not expired; when the ferrous ion solution appears yellow, it indicates that the consumables are expired. By observing the depth of the color, it is also possible to determine which stage the consumables are in.

[0021] like Figure 1As shown, an observation window 7 is provided on the card body 1 at a position corresponding to the transparent container 2 . The observation window 7 is closed by transparent glass, so as to facilitate observation of the color change of the ferrous ion solution in the transparent container 2 .

[0022] like Figure 2 As shown, an exhaust pipe 10 is connected through the bottom of the gas cylinder 8, and a one-way valve 11 is installed on the exhaust pipe 10 to discharge oxygen and allow the oxygen to enter the inner cavity.

[0023] In this embodiment, a threaded groove 13 and a limit groove 15 are provided on the top of the plunger 9, a threaded rod 14 is screwed into the threaded groove 13, the threaded rod 14 is rotatably installed on the inner top wall of the inner cavity, a limit rod 16 is movably inserted into the limit groove 15, and the top end of the limit rod 16 is fixedly installed on the inner wall of the gas cylinder 8. When the threaded rod 14 rotates, it can drive the plunger 9 to move downward, thereby discharging the oxygen in the gas cylinder 8, and the limit rod 16 plays a limiting role to prevent the plunger 9 from rotating.

[0024] The rotation of the threaded rod 14 can be controlled manually or electrically driven. In this embodiment, the electric drive method is selected. Specifically, Figure 4 As shown, a driven wheel 17 is fixedly mounted on the outer wall at the top end of the threaded rod 14, and a driving wheel 18 is meshed with the outer wall of the driven wheel 17. The driving wheel 18 is driven to rotate by a motor 19 fixedly mounted on the inner top wall of the inner cavity. Thus, the operation of the motor 19 can drive the threaded rod 14 to rotate, thereby moving the plunger 9.

[0025] like Figure 6 As shown, an installer 22 is also provided on the back of the card body 1. The installer 22 can be a magnetic block or an adhesive sticker to be adsorbed or adhered to the outer box, cabinet, etc. of the consumables.

[0026] Embodiment 2: See also Figure 5 On the basis of the first embodiment, in this embodiment, an RFID tag 21 is further provided, and the RFID tag 21 can be adhered to the outer box of the consumables, and a main control board 20 for identifying the RFID tag 21 is installed in the inner cavity, and the output end of the main control board 20 is electrically connected to the input end of the motor 19; When in use, the card body 1 is placed close to the RFID tag 21 on the outer box of the consumables, and the main control board 20 automatically reads the information to obtain the remaining validity period of the consumables. Then, the main control board 20 controls the motor 19 to run and release a corresponding amount of oxygen according to the validity period data, so that the color change of the iron ion solution matches the validity period of the consumables. The specific RFID technology is not repeated in this embodiment.

[0027] By precisely controlling the amount of oxygen entering the inner cavity, the rate of the oxidation reaction can be regulated, thereby making the color change process of the ferrous ion solution more controllable. According to the shelf life of the consumables, the amount of oxygen entering can be controlled to achieve a precise match with the shelf life of the consumables.

[0028] Taking a disposable syringe as an example, the card body 1 of the present invention is fixed outside the syringe packaging box. When the syringe is produced, its RFID tag information (including production date, expiration date, etc.) is entered into the system. When the syringe is put into storage or distributed for use, the card body 1 is automatically adjusted to the correct starting color by scanning the RFID tag. Over time, the color of the color card gradually changes until it completely turns yellow, indicating expiration. Medical staff can quickly determine whether the syringe is usable by simply observing the color of the color card.

[0029] The color-changing consumables management indicator card of the present invention not only greatly simplifies the validity period management process of medical consumables and improves management efficiency, but also effectively avoids the misuse of expired consumables through intuitive color changes, ensuring medical quality and patient safety. In addition, its intelligent and environmentally friendly design concept also conforms to the development trend of modern medicine, and has broad market application prospects and social value.

[0030] Embodiment three: See also Figure 2 and Figure 3 On the basis of the first embodiment, in this embodiment, the transparent container 2 is fixed in the positioning sleeve 3, the bottom end of the positioning sleeve 3 is positioned by the positioning plate 4, and the top end is inserted in the top groove 5. Specifically, the positioning plate 4 is fixedly installed on the inner bottom wall of the inner cavity, and the top groove 5 is opened on the inner top wall of the inner cavity. In this way, the positions of the positioning sleeve 3 and the transparent container 2 can be effectively fixed, and the positioning sleeve 3 and the transparent container 2 can also be conveniently disassembled for replacement and reuse.

[0031] like Figure 2 As shown, the top of the top groove 5 is closed by a sealing cap 6 .

[0032] In the present invention, an inflation nozzle 12 is also provided at the bottom of the gas cylinder 8 for replenishing oxygen into the gas cylinder 8 for reuse; in addition, a vacuum nozzle (not shown in the figure) is also provided on the outer wall of the card body 1 for vacuuming the inner cavity.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
