Description

Technical Field

[0001] The utility model relates to the technical field of sterilizers, in particular to a drug adding device for an ethylene oxide sterilizer. Background Art

[0002] Ethylene oxide sterilizer is a key equipment for manufacturers of disposable sterile medical devices. It has special requirements for installation, operation and use management. Ethylene oxide is used as a sterilizer. Ethylene oxide is a broad-spectrum sterilizer that can kill various microorganisms at room temperature, including spores, Mycobacterium tuberculosis, bacteria, viruses, fungi, etc. During the sterilization process, the sterilization chamber is first evacuated by a vacuum pump.

[0003] After searching, the patent document with announcement number: CN220656032U discloses an automatic dosing device for an ethylene oxide sterilizer. The device installs the ethylene oxide cylinder inside the movable box by pulling the movable box, and then pushes the movable box to fix it inside the sterilization cabinet. When the ethylene oxide required for sterilization is insufficient, it is convenient for people to replace the ethylene oxide cylinder, and the sterilization effect of the sterilization cabinet can be prevented from being affected when the ethylene oxide cylinder is replaced.

[0004] When the above device replaces the ethylene oxide cylinder, the two connectors need to be disassembled and assembled with the two ethylene oxide cylinders in turn, which makes the replacement of the ethylene oxide cylinders more complicated when there are many instruments to be sterilized. Therefore, we propose a dosing device for an ethylene oxide sterilizer to solve the above problem. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in 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.

[0023] A circular ring 3 is fixedly installed inside the sterilizer body 1, and a circular plate 4 is rotatably connected to the inner wall of the circular ring 3. The circular ring 3 assists the circular plate 4 in rotation and prevents the ethylene oxide cylinder 7 from moving during rotation. A plurality of placement grooves 5 are provided on the outer wall of the circular plate 4, and a bottle adding hole 6 is provided on the outer wall of the circular ring 3. After all the ethylene oxide cylinders 7 are finished, new ethylene oxide cylinders 7 are added through the bottle adding hole 6, and ethylene oxide cylinders 7 are placed inside the placement grooves 5.

[0024] A through hole 8 is provided at the top of the ring 3, a sliding hole 9 is provided at the bottom of the ring 3, a material drop groove 10 is provided inside the sterilizer body 1, a collection frame 11 is placed inside the sterilizer body 1, and the ethylene oxide gas cylinder 7 falls into the collection frame 11 along the placement groove 5, the sliding hole 9 and the material drop groove 10.

[0025] A servo motor 15 is fixedly installed inside the sterilizer body 1. A circular hole is opened on the outer wall of the ring 3. The inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the servo motor 15. One end of the output shaft of the servo motor 15 is fixedly connected to the outer wall of the circular plate 4. The operation of the servo motor 15 drives the circular plate 4 to rotate, so that the ethylene oxide cylinder 7 is located below the ejector pin 14.

[0026] An air outlet mechanism is provided on the outer wall of the ring 3, and the air outlet mechanism includes a pin 14. The top of the ring 3 is fixedly connected to a frame 12, and an electric push rod 13 is fixedly connected to the inside of the frame 12. The bottom of the output end of the electric push rod 13 is fixedly connected to the top of the pin 14, and a plurality of air outlet holes 16 are opened on the outer wall of the frame 12.

[0027] Working principle: Place the instrument to be sterilized into the stainless steel mesh basket 2, and then place it into the sterilizer body 1, and place it in front of the ring 3. The servo motor 15 drives the circular plate 4 to rotate. When one of the ethylene oxide cylinders 7 is located below the ejector 14, the servo motor 15 stops rotating. At the same time, the last used ethylene oxide cylinder 7 falls into the collection frame 11 along the placement groove 5, the slide hole 9 and the blanking groove 10. The electric push rod 13 drives the ejector 14 downward. The ejector 14 moves downward to pierce the top cover of the ethylene oxide cylinder 7. The ethylene oxide gas in the ethylene oxide cylinder 7 is released and discharged from multiple air outlets 16, and part of it is discharged from the gap between the ring 3 and the circular plate 4. The ethylene oxide gas fills the room of the sterilizer body 1 to sterilize the instrument. After the disinfection is completed, the exhaust gas is purified by the existing purifier, and then the sealed door is opened to take out the stainless steel mesh basket 2.
