Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure sterilization devices, in particular to a high-pressure sterilization device for a hospital disinfection supply room. Background Art

[0002] The Sterile Supply Room (SSR) is the hospital's supply unit for sterile items. It is responsible for the cleaning, packaging, sterilization, and supply of medical equipment. The SSR can sterilize medical equipment in a variety of ways, including the use of an autoclave when high-pressure sterilization is required.

[0003] When sterilizing medical equipment in existing autoclaves, the equipment is typically placed in a sterilization frame before being placed inside the autoclave for high-pressure sterilization. However, the sterilization frame's hollow mesh structure makes it difficult to concentrate high-pressure steam. Consequently, the high-pressure steam in the autoclave is evenly distributed, sterilizing the equipment and resulting in low sterilization efficiency. To address this issue, we propose a high-pressure sterilization device for hospital disinfection supply rooms. Utility Model Content

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0021] As attached Figure 1-4 The shown embodiment is a high-pressure sterilization device for a hospital disinfection supply room, comprising a base 1, foot pads 2 are provided at the four corners of the lower surface of the base 1, a controller 3 is installed on one side of the upper surface of the base 1, a sterilization cylinder 4 is installed on the other side above the base 1, a heater 5 is installed on the lower surface of the sterilization cylinder 4, a movable shaft 6 is provided on one side of the upper surface of the sterilization cylinder 4, a limit baffle 7 is provided on the other side of the upper surface of the sterilization cylinder 4, a handle 8 is installed on the movable end of the sterilization cylinder 4 through the movable shaft 6, an adjusting screw 9 is inserted through the middle of the upper surface of the handle 8, a sealing cover 10 is installed on the output end of the adjusting screw 9 through a bearing, a pressure relief valve 11 is installed on the rear end of the upper surface of the sealing cover 10, a pressure gauge 12 is installed on the front end of the upper surface of the sealing cover 10, a limit block 13 is installed on one side of the outer surface of the sealing cover 10, the limit block 13 is clamped into the limit baffle 7, and a sealing ring is provided on the inner ring surface of the sealing cover 10.

[0022] A positioning ring 14 is provided on the lower part of the inner surface of the sterilization cylinder 4, and a support plate 15 is placed on the upper surface of the positioning ring 14. The diameter of the support plate 15 is equal to the diameter of the inner ring surface of the sterilization cylinder 4. An opening is provided in the middle of the upper surface of the support plate 15, and a first funnel-shaped pressure collecting plate 16 is inserted and installed through the inner surface of the opening of the support plate 15. A second funnel-shaped pressure collecting plate 17 is mounted on the upper surface of the first pressure collecting plate 16, and a support net 18 is placed and installed on the inner surface of the first pressure collecting plate 16. Openings are provided in the middle of the end faces of the first pressure collecting plate 16 and the second pressure collecting plate 17 with smaller diameters. The diameter of the opening opened on the end face of the second pressure collecting plate 17 is larger than the diameter of the opening opened on the end face of the first pressure collecting plate 16.

[0023] During operation, deionized water can first be added into the sterilization cylinder 4 to reach the water level line of the positioning ring 14. At this time, the support plate 15 can be placed on the upper surface of the positioning ring 14, and the first pressure collecting plate 16 can be inserted into the middle opening of the upper surface of the support plate 15. At this time, the support net 18 can be placed in the first pressure collecting plate 16, and the medical equipment to be sterilized can be placed on the support net 18. At this time, the second pressure collecting plate 17 can be covered to the upper surface of the first pressure collecting plate 16. In this case, the first pressure collecting plate 16 and the second pressure collecting plate 17 can together form a closed high-pressure sterilization space, which is conducive to gathering high-pressure steam to improve the sterilization efficiency. When the space in the sterilization cylinder 4 is sufficient, multiple first pressure collecting plates 16 and second pressure collecting plates 17 can be stacked and combined, which is conducive to achieving the effect of classified placement of medical equipment and increasing the number of medical equipment sterilized at a single time.

[0024] When the medical equipment is placed, the sealing cover 10 can be moved to the top of the sterilization cylinder 4 through the handle 8 and the movable shaft 6, and the end of the handle 8 away from the movable shaft 6 will be stuck in the limit baffle 7, and the limit block 13 set on the outer surface of the sealing cover 10 will be synchronously stuck in the limit baffle 7. In this case, the adjusting screw 9 can be turned clockwise to control the sealing cover 10 to seal the opening of the sterilization cylinder 4 with the cooperation of the bearing. At this time, the heater 5 can be controlled by the controller 3 to start heating the deionized water in the sterilization cylinder 4. When the deionized water is heated, a large amount of high-temperature steam will be generated, thereby causing the sterilization cylinder 4 to be heated. The air pressure increases, and the high-temperature steam generated on the bottom surface of the sterilization cylinder 4 will enter the first pressure collecting plate 16 through the openings opened on the lower surface of the support plate 15 and the first pressure collecting plate 16. Since the high-pressure sterilization space composed of the first pressure collecting plate 16 and the second pressure collecting plate 17 is funnel-shaped, in this case, the efficiency of discharging the high-temperature steam entering the first pressure collecting plate 16 and the second pressure collecting plate 17 is reduced, so that the high-temperature steam can stay in the first pressure collecting plate 16 and the second pressure collecting plate 17 for a longer time, avoiding the state of uniform distribution of high-pressure steam in the sterilization cylinder 4, which is beneficial to the effect of gathering high-pressure steam to comprehensively sterilize medical equipment and improve the sterilization efficiency.

[0025] In summary: the high-pressure sterilization device can concentrate high-pressure steam and thus reduce the sterilization space, which is beneficial to concentrate high-pressure steam to fully sterilize medical equipment and improve the sterilization efficiency.

[0026] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
