The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0020] In this embodiment, after loading the dressing into the loading box 6, the loading box 6 is clamped onto the metal heating cylinder 5, and then the cylinder cover 4 is closed. The inside of the second heat insulation cylinder 22 is heated by the electric heater 21. When heating, a sterilization medium (such as water, air, etc.) is filled into the second heat insulation cylinder 22. The electric heater 21 is an electromagnetic heater.

[0024] Example 3: Refer to Figures 1 - 9 , a sterilization device for producing a sterile wound repair dressing, including a base 1, further including: a bracket 11 fixedly installed on the base 1, a first heat insulation cylinder 2 fixedly installed on the bracket 11, and cylinder covers 4 provided at both ends of the first heat insulation cylinder 2; an electric heater 21 fixedly installed on the inner wall of the first heat insulation cylinder 2; a roller 23 rotatably installed on the side wall of the first heat insulation cylinder 2, and a second heat insulation cylinder 22 is rollingly arranged on the roller 23; a metal heating cylinder 5 provided in the second heat insulation cylinder 22, a loading box 6 is snap-fitted on the metal heating cylinder 5, and the dressing is stored in the loading box 6; when sterilizing by heating in the second heat insulation cylinder 22, the second heat insulation cylinder 22 drives the loading box 6 to rotate around the axis of the second heat insulation cylinder 22.

[0025] Refer to Figure 1 and Figure 7, a mounting seat 41 is fixedly installed on the outer wall of the first heat insulation cylinder 2, a hinge seat 42 is fixedly installed on the cylinder cover 4, the hinge seat 42 is hinged to the mounting seat 41, a second motor 43 is fixedly installed on the mounting seat 41, the output shaft of the second motor 43 is fixedly connected to the hinge seat 42, and a sealing ring 44 is rotatably installed on the cylinder cover 4. After the cylinder cover 4 is closed, the sealing ring 44 abuts against and seals the end of the second heat insulation cylinder 22.

[0026] Start the second motor 43. The second motor 43 drives the hinge seat 42 to rotate, and the hinge seat 42 drives the cylinder cover 4 to rotate, thereby controlling the opening or closing of the cylinder cover 4. After the cylinder cover 4 is closed, the sealing ring 44 abuts against and seals the wall of the end of the second heat insulation cylinder 22.

[0027] Among them, two sets of cylinder covers 4 are provided, which are respectively arranged at both ends of the first heat insulation cylinder 2. The cylinder covers 4 at both ends can be opened simultaneously, and then feeding can be carried out from both ends, thereby improving the feeding speed.

[0028] In summary, in this embodiment, by introducing the second motor 43 and the corresponding transmission mechanism, the automatic opening and closing of the cylinder cover 4 are realized, manual operation is reduced, the automation degree of the equipment is improved, and the design of feeding from both ends at the same time greatly shortens the feeding time and improves the production efficiency. The design of the sealing ring 44 ensures the sealing performance of the cylinder cover 4 when it is closed, avoids the leakage of high-temperature medium, and thus ensures the sterilization effect.

[0029] Example 4: Refer to Figures 1 - 9 , a sterilization device for producing sterile wound repair dressings, including a base 1, and further including: a bracket 11 fixedly installed on the base 1, a first heat insulation cylinder 2 fixedly installed on the bracket 11, and cylinder covers 4 arranged at both ends of the first heat insulation cylinder 2; an electric heater 21 fixedly installed on the inner wall of the first heat insulation cylinder 2; a roller 23 rotatably installed on the side wall of the first heat insulation cylinder 2, and a second heat insulation cylinder 22 is rollingly arranged on the roller 23; a metal heating cylinder 5 is arranged inside the second heat insulation cylinder 22, a loading box 6 is snap-fitted on the metal heating cylinder 5, and dressings are stored in the loading box 6; when sterilization is carried out inside the second heat insulation cylinder 22, the second heat insulation cylinder 22 drives the loading box 6 to rotate around the axis of the second heat insulation cylinder 22. Refer to Figures 3 - 7 , a sealing cavity is arranged inside the cylinder cover 4, a third motor 7 is fixedly installed inside the sealing cavity, and the output shaft of the third motor 7 extends outside the sealing cavity and is fixedly installed with a circulation fan 71.

[0030] In this embodiment, start the third motor 7. The third motor 7 drives the circulation fan 71 to rotate. When the circulation fan 71 rotates, it sucks the high-temperature medium between the interlayer of the second heat insulation cylinder 22 and the metal heating cylinder 5, and then blows it into the inside of the metal heating cylinder 5 from the end of the metal heating cylinder 5, so that the high-temperature medium circulates and flows, improving the efficiency of high-temperature sterilization of dressings.

[0031] In this embodiment, the high-temperature medium is circulated by the circulation fan 71, so that the high-temperature medium can contact the dressing more effectively, thereby improving the high-temperature sterilization efficiency of the dressing. At the same time, the circulation of the high-temperature medium also further helps to evenly distribute the heat inside the second heat insulation cylinder 22, reducing the problem of uneven temperature caused by the accumulation of the high-temperature medium.

[0032] Refer to Figures 3 - 8 , the loading box 6 includes a box body 61. Moving wheels 64 are rotatably installed at the bottom of the box body 61. Vent holes 62 for the high-temperature medium to pass through are provided on the box wall of the box body 61. Installation strips 51 are fixedly installed on the outer wall of the metal heating cylinder 5. The installation strips 51 are fixedly connected to the inner wall of the second heat insulation cylinder 22. First ventilation grooves 52 are provided on the cylinder wall of the metal heating cylinder 5. Second ventilation grooves 53 communicating with the inside of the metal heating cylinder 5 are provided on the installation strips 51.

[0033] Among them, during the circulation process, the high-temperature medium passes through the first ventilation groove 52 and the second ventilation groove 53 and moves to the cavity between the second heat insulation cylinder 22 and the metal heating cylinder 5, and then is drawn into the chamber where the circulation fan 71 is located by the circulation fan 71, and then enters the middle of multiple loading boxes 6 under the drive of the circulation fan 71.

[0034] Among them, during the circulation process, the high-temperature medium passes through the pores on the dressing, raising the temperature of the dressing, thereby achieving sterilization.

[0035] Refer to Figures 4 - 6 and Figure 8 , an installation frame 54 is fixedly installed on the inner wall of the metal heating cylinder 5. A limiting plate 55 is fixedly installed on the installation frame 54. A guide groove 56 is provided on the limiting plate 55. A guide rail strip 63 is fixedly installed on the outer wall of the loading box 6. When the loading box 6 moves to the inside of the metal heating cylinder 5, the guide rail strip 63 is inserted into the guide groove 56.

[0036] In this embodiment, the guide rail strip 63 is aligned with the guide groove 56, and then the loading box 6 is pushed. Under the action of the moving wheels 64, the loading box 6 moves on the limiting plate 55, thereby transporting the loading box 6 into the metal heating cylinder 5. When the metal heating cylinder 5 is turned over, the guide rail strip 63 abuts against the guide groove 56, thereby preventing the loading box 6 from sliding.

[0037] Refer to Figure 1 and Figure 2 , a storage box 8 is fixedly installed on the base 1. A suction pump 81 is fixedly installed on the outer wall of the storage box 8. The input end of the suction pump 81 is connected to the storage box 8. The output end of the suction pump 81 is communicated with the inside of the cylinder cover 4 through a transmission pipe 82. In this embodiment, the sterilization medium in the storage box 8 is sucked into the metal heating cylinder 5 by the suction pump 81.

[0038] As Figure 9 shown, furthermore, a filter block is provided in the storage tank 8, and the filter block is preferably activated carbon. One group of the two suction pumps 81 is used to suck the sterilization medium into the storage tank 8, and the other group is used to suck the sterilization medium into the metal heating cylinder 5. After sterilization is completed, the gaseous sterilization medium is compressed into the storage tank 8. After the dressing is replaced, the filtered high-temperature sterilization medium is sent into the metal heating cylinder 5 again. Among them, when the sterilization medium is compressed into the storage tank 8, the heat can be further increased.

[0039] In summary, the device uses an electromagnetic heater to heat the metal heating cylinder 5. This method not only has a fast heating speed, but also has a high energy conversion efficiency. During the heating process, the high-temperature medium (such as high-temperature steam) inside the metal heating cylinder 5 is driven by the circulation fan 71 to circulate around the dressing, ensuring uniform heating of the dressing and improving the sterilization efficiency.

[0040] The opening and closing of the cylinder cover 4 are driven by the second motor 43, realizing automatic operation, reducing manual intervention, and improving work efficiency. Moreover, both ends of the device can be loaded, and this design speeds up the loading speed and further improves the production efficiency.

[0041] The rotating design of the second heat insulation cylinder 22, combined with the disturbance of the high-temperature medium by the metal heating cylinder 5, effectively prevents the accumulation of the high-temperature medium in the cylinder and ensures the uniformity of the temperature distribution. Among them, the matching design of the guide rail strip 63 and the guide groove 56 ensures the stable rotation of the loading box 6 in the metal heating cylinder 5 and avoids the displacement or scattering of the dressing during the sterilization process.

[0042] The device is equipped with a storage tank 8 for storing and recycling the sterilization medium, which not only reduces the waste of the medium but also reduces the operating cost. The filter block (such as activated carbon) in the storage tank 8 can effectively filter and purify the sterilization medium to ensure the purity and sterilization effect of the medium when it is reused.

[0043] A method for using a sterilization device for producing sterile wound repair dressings includes the following steps: S1. Store the dressing in the loading box 6, and then open the cylinder cover 4 and insert the loading box 6 into the metal heating cylinder 5; S2. Close the cylinder cover 4, send the medium into the second heat insulation cylinder 22, and use the electric heater 21 and the metal heating barrel to cooperate to heat the medium; S3. During the process of the medium heating up and maintaining the heat preservation, use the second heat insulation cylinder 22 to drive the loading box 6 to rotate.
