Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] According to an embodiment of this utility model, this application discloses a transfer device for ethylene oxide sterilization, referring to... Figure 1 and Figure 2 The system includes a mobile platform 1, a sterilization circulation chamber 2, an equipment box 4, a power lifting mechanism, and a clamping assembly 5.

The sterilization circulation chamber 2 is mounted on the mobile platform 1 and is used to store and transport sterilized instruments or items. The top of the sterilization circulation chamber 2 has a removable sealing cover 3, with a sealing ring made of silicone material between the sealing cover 3 and the sterilization circulation chamber 2. A groove on the top of the sterilization circulation chamber 2, which is embedded in the groove of the contact surface between the sealing cover 3 and the sterilization circulation chamber 2, forms a sealed environment to prevent gas leakage.

A partition 13 is provided in the center of the ventilation jacket 11, which divides the ventilation jacket 11 into an upper channel and a lower channel. The equipment box 4 is located outside the analysis and circulation chamber 2, and a gas circulation device is installed inside the equipment box 4.

The outlet of the activated carbon box is connected to the inlet of the desorption circulation box 2 via a pipe. The outlet of the desorption circulation box 2 is connected to the inlet of the blower. When the blower is turned on, gas enters from the inlet of the activated carbon box, passes through the activated carbon, and then enters the desorption circulation box for gas circulation. After gas circulation, it exits from the outlet of the desorption circulation box 2, forming a closed loop, thus forming a gas circulation purification circuit. The outer side of the equipment box 4 is provided with a removable cover plate 41, which is fixed to the equipment box 4 with bolts for easy maintenance and replacement of the activated carbon adsorbent 10.

[0026] Reference Figure 1 A power lifting mechanism is mounted on the mobile platform 1 to move the sealing cover 3 up and down and back and forth.

Through the coordinated action of the first power telescopic rod 73 and the second power telescopic rod 81, precise position adjustment of the sealing cover 3 within space is achieved.

[0027] Reference Figure 2The clamping assembly 5 is disposed on the lower surface of the sealing cover 3 and is used to clamp the product transfer box 6.

The fixed end of each hydraulic telescopic rod 53 is fixed to the sealing cover 3 by bolts, and the telescopic end is connected to the corresponding clamping slider 52 through a connector to drive the clamping slider 52 to slide along the guide rod 51. A clamping plate 54 is installed on the lower surface of the clamping slider 52. The outer side of the clamping plate 54 is provided with a slot 541. The shape and size of the slot 541 are adapted to the locking block 61 on the outer side of the product transfer box 6. The clamping and releasing of the product transfer box 6 is realized by the extension and retraction of the hydraulic telescopic rod 53. The mobile platform 1 is internally embedded with a rechargeable lithium battery pack, which is connected to the electrical components in the device via wires to provide power to the device. The power of the power lifting mechanism and clamping assembly can also be controlled by an external hydraulic station.

[0028] The implementation process of a transfer device for ethylene oxide sterilization according to an embodiment of this application is as follows: The product to be transferred is loaded into the product transfer box. After the device is started, the second power telescopic rod extends vertically to lift the sealing cover. Then, the first power telescopic rod extends horizontally to push the translation slider along with the sealing cover to the top of the product transfer box. Then, the hydraulic telescopic rod retracts, causing the slot on the clamping plate to lock the locking block on the outer side of the product transfer box, completing the clamping action. Then, the second power telescopic rod extends vertically again to lift the product transfer box. The first power telescopic rod retracts horizontally to bring the product transfer box to the top of the analytical circulation box. The second power telescopic rod then retracts vertically to cover the sealing cover on the upper surface of the analytical circulation box. At this time, the product transfer box is located inside the analytical circulation box. Then, the moving platform is started to transfer the analytical circulation box to the designated work position. During the transfer process, the fan installed in the equipment box is started as needed. When the fan is working, the gas in the analytical circulation box is extracted through the pipeline and sent to the activated carbon adsorption element for purification treatment. The purified gas is then returned to the interior of the analytical circulation box through the pipeline, forming a gas circulation purification loop. Once the equipment box is moved to the designated workstation, it can be removed from the analytical circulation box and placed at the designated workstation using the hydraulic telescopic rod.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
