Description

Technical Field

[0001] The invention relates to the technical field of sterilization devices, and in particular to a high-temperature steam sterilization device with multi-point air intake. Background Art

[0002] The contents in this section merely provide background information related to the present invention and may not constitute prior art.

[0003] A sterilizer is an instrument that can kill and remove all microorganisms on the transmission medium, including bacterial spores and non-pathogenic microorganisms. It usually includes three methods: moist heat disinfection and sterilization, dry heat disinfection and sterilization, and chemical disinfection and sterilization. Steam sterilizers are widely used in the medical field. Steam sterilizers are moist heat disinfection and sterilization equipment, usually composed of a disinfection chamber, a control system, an overpressure protection device, etc. The high-temperature water vapor generated is used to act on the microorganisms loaded for a certain period of time, causing the microbial protein to denature and cause the microorganism to die, thereby achieving the purpose of disinfection.

[0004] In the actual use of traditional high-temperature steam sterilization devices, the items to be sterilized are first placed in the high-temperature sterilization device. After closing the door, high-temperature steam is introduced into the sterilization device through the air intake pipe. In the subsequent disinfection process, the high-temperature steam fills the sterilization device and the surface of the items to be sterilized is disinfected by the high-temperature and high-heat steam.

[0005] However, the above-mentioned related technologies have the following defects. In actual use, there is only one pipe leading to the sterilization device. The high-temperature and hot steam needs a period of time to diffuse to fill the internal space of the sterilization device. The short diffusion time will also cause uneven temperature inside the sterilization device. It is difficult to achieve the same disinfection effect for items to be sterilized of different sizes within the same disinfection time. It is necessary to extend the ventilation time of the high-temperature steam, thereby extending the disinfection time. This not only increases the disinfection cost, but also reduces the efficiency of disinfection. Summary of the invention

[0052] Reference Fig. 9 A sealing ring 69 is provided on the storage hole 64, and the inner diameter of the sealing ring 69 is larger than the aperture of the storage hole 64. As an embodiment of the present application, the material of the sealing ring 69 is set to be silicone rubber. In actual use, the gap between the top of the storage box 6 and the bottom of the water outlet 4 is sealed by the sealing ring 69, so as to form a relatively closed space between the inside of the sterilization box body 1 and the inside of the storage box 6. During the sterilization process, with the continuous infusion of high-temperature steam, a positive pressure high-temperature and high-pressure sterilization environment is gradually formed inside the sterilization box body 1, so that the medical devices placed inside the sterilization box body 1 can be effectively sterilized.

[0053] During the sterilization process, after the high-temperature steam contacts the inner cavity side wall of the sterilization box body 1, as the sterilization time increases, the high-temperature steam gradually condenses into water droplets. The condensed water droplets are first filtered through the filter net 41. After the filtration is completed, the water droplets gradually gather and fall, and flow into the water outlet 4. Then the water droplets pass through the water outlet 4 into the storage hole 64 below, and finally the water droplets condensed by the high-temperature steam are collected by the storage box 6.

A silicone plug 67 is provided at one end of the water outlet pipe 66 away from the storage box 6. The opening of the water outlet pipe 66 is blocked by the silicone plug 67 to prevent condensed water from flowing out of the storage box 6 through the water outlet pipe 66 during the disinfection process. After the disinfection is completed, the silicone plug 67 is opened to pour out the condensed water in the storage box 6 through the water outlet pipe 66.

[0055] Reference Fig.10 As an embodiment of the present invention, an arc-shaped collection block 68 is provided at the bottom of the storage box 6. Two arc-shaped collection blocks 68 are provided. The two arc-shaped collection blocks 68 are symmetrically arranged on both sides of the through hole 65. The arc-shaped concave surface of the arc-shaped collection block 68 is inclined upward toward the storage hole 64. Fig.10As shown, the condensed water falls into the storage bin 62 through the storage hole 64 and drips onto the arc-shaped collecting block 68. Since the surface of the arc-shaped collecting block 68 is inclined, the condensed water automatically gathers in the direction of the perforation 65 under the action of its own gravity. When the condensed water in the storage bin 62 needs to be poured out, the silicone plug 67 can be opened to more conveniently pour out the condensed water in the storage bin 62.

[0056] Reference Fig. 9 , 10 A guide block 71 is provided at the top of the storage box 6. There are multiple guide blocks 71. The multiple guide blocks 71 are evenly arranged along the length direction of the storage box 6. The width of the guide block 71 is adapted to the width of the through groove 12. The spacing between adjacent guide blocks 71 is adapted to the width of the annular reinforcement rib 11. The limiter 7 is used to limit the position of the guide block 71 in the through groove 12.

[0057] Reference Fig.10 , 11 As an embodiment of the present invention, a limiting block 72 is fixedly provided at both ends of one of the guide blocks 71, and a receiving hole 73 is provided on the side wall of the limiting block 72. There are two receiving holes 73, and the two receiving holes 73 are symmetrically provided on both sides of the limiting block 72 along the length direction of the limiting block 72. The limiting member 7 is configured as a limiting pin, and a limiting member 7 is slidably provided in each receiving hole 73. An elastic member 74 is provided in the receiving hole 73, and the elastic member 74 is configured as a spring. One end of the spring is fixedly connected to the limiting member 7, and the other end is fixedly connected to the inner wall of the receiving hole 73. A driving member 75 is provided on the limiting block 72, and the driving member 75 is used to drive the limiting member 7 to move toward the receiving hole 73.

[0058] Reference Fig.11 As an embodiment of the present invention, the driving member 75 is configured as a driving plate, a sliding hole 76 is opened at the top of the limit block 72 along the length direction of the accommodating hole 73, a sliding block 77 is slidably arranged in the sliding hole 76, the driving member 75 is slidably arranged on the top of the limit block 72, one end of the sliding block 77 is fixedly connected to the limit member 7, and the other end is fixedly connected to the bottom of the driving member 75.

[0059] Before sterilizing the articles, the storage box 6 needs to be installed first, and the storage box 6 needs to be moved onto the support frame 5. By driving the two driving members 75 to move in a direction close to each other, that is, pinching the two driving members 75, the driving member 75 can drive the limiting member 7 to move toward the receiving hole 73, so that the limiting member 7 completely enters the receiving hole 73, and then drives the storage box 6 to move horizontally on the support frame 5, driving the guide block 71 and the strip block 61 to slide into the through groove 12. When the limiting block After 72 passes through the through slot 12 and comes out from the other side, the inner wall of the through slot 12 no longer blocks the accommodating hole 73. At this time, the limiting member 7 can extend out of the accommodating hole 73 under the action of the elastic member 74. Since the two limiting blocks 72 are arranged on both sides of the guide block 71, a limiting member 7 is provided on each limiting block 72. At this time, the side wall of the limiting member 7 abuts against the side wall of the annular reinforcement rib 11, thereby being able to limit the position of the guide block 71 in the through slot 12, thereby completing the installation of the storage box 6.

[0060] After completing the disinfection and sterilization of the items, select the limit block 72 on any side to drive the driving member 75 on the limit block 72 to move in a direction close to each other. At this time, the driving member 75 can drive the limit member 7 to move toward the accommodating hole 73, so that the limit member 7 re-enters the accommodating hole 73, and then the storage box 6 can be driven to move along the length direction of the guide block 71 on the support frame 5, so that the limit block 72 on the selected side enters the through groove 12, and at the same time, the limit block 72 on the other side moves in a direction away from the sterilization box body 1, and the disassembly of the storage box 6 is completed. After the storage box 6 is removed from the support frame 5, the silicone plug 67 can be opened to pour out the condensed water collected in the storage box 6.

[0061] Reference Fig.11As an embodiment of the present invention, the end of the stopper 7 away from the receiving hole 73 is set as an inclined surface 8. Due to the setting of the inclined surface 8, the stopper 7 is in a right-angle trapezoidal structure. The end surface of the stopper 7 close to the sterilization box body 1 is a large end surface, and the end surface of the stopper 7 away from the sterilization box body 1 is a small end surface. The end area of ​​the stopper 7 close to the sterilization box body 1 is significantly larger than the end area of ​​the far end of the sterilization box body 1. The inclined surface 8 is used to abut the side wall of the through groove 12. When the storage box 6 is installed in place, the large end surface of the stopper 7 abuts against the outer end surface of the annular reinforcing rib 11. When installing the storage box 6, first drive the storage box 6 to move to a position flush with the height of the support frame 5, then align the guide block 71 and the strip block 61 with the position of the through groove 12, and then drive the storage box 6 to move toward the bottom of the sterilization box body 1, and the limit block 72 located on the side of the guide block 71 is first inserted into the through groove 12. As the storage box 6 moves further, the inclined surface 8 of the limit member 7 located on the limit block 72 abuts against the side wall of the through groove 12. As the storage box 6 moves further, the limit member 7 is pushed into the accommodating hole 73 under the extrusion of the side wall of the through groove 12. Then, the storage box 6 is continuously driven to move to complete the installation of the storage box 6. When the storage box 6 is installed in place, the large end face of the limit member 7 abuts against the outer end face of the annular reinforcement rib 11. By providing the inclined surface 8, when installing the storage box 6, there is no need to manually drive the driving member 75 to move to drive the limiting member 7 to enter the receiving hole 73, which further simplifies the operating steps of the staff and improves the work efficiency of the staff.

[0062] As an embodiment of the present invention, a sliding layer is covered on the inclined surface 8, and the material of the sliding layer is set to polytetrafluoroethylene. During actual use, the friction between the sliding layer and the side wall of the annular reinforcement rib 11 can be effectively reduced, further facilitating the staff to install the storage box 6.

[0063] In addition, as a possible embodiment of the present invention, an anti-skid pad is provided on the side walls of the driving member 75 that are away from each other. The material of the anti-skid pad is set to silicone rubber. Silicone rubber has a certain water absorption and anti-skid effect. It can effectively avoid slipping between the staff's hands and the side walls of the driving member 75 during the process of moving the driving member 75, thereby improving the user experience during use.

[0064] The implementation principle of a high-temperature steam sterilization device with multiple air intake points proposed in an embodiment of the present invention is as follows:

[0065] When the articles are sterilized with high-temperature steam, the storage box 6 needs to be installed first, and the storage box 6 needs to be moved onto the support frame 5. The two driving members 75 are driven to move toward each other, that is, the two driving members 75 are pinched. At this time, the driving member 75 can drive the limiting member 7 to move toward the accommodating hole 73, so that the limiting member 7 completely enters the accommodating hole 73, and then the storage box 6 needs to be moved horizontally on the support frame 5, and the guide block 71 and the strip block 61 need to slide into the through groove 12. When the limiting member 7 is moved, the guide block 71 and the strip block 61 are moved horizontally. After the positioning block 72 passes through the through slot 12 and comes out from the other side, the inner wall of the through slot 12 no longer blocks the accommodating hole 73, and the limiting member 7 can extend out of the accommodating hole 73 under the action of the elastic member 74. Since the two limiting blocks 72 are respectively arranged on both sides of the guide block 71, a limiting member 7 is arranged on each limiting block 72. At this time, the large end surface of the limiting member 7 abuts against the outer end surface of the annular reinforcing rib 11, and the position of the guide block 71 in the through slot 12 can be limited, thereby completing the installation of the storage box 6;

[0066] After completing the installation of the storage box 6, the external high-temperature steam is connected to the steam inlet 25 at the top of the horizontal tube 231, and then the angle seat valves 24 on the two vertical tubes 232 are opened, and the external high-temperature steam can enter the first air inlet passage 21 and the second air inlet passage 22 respectively through the connecting pipe 23, and then enter the first branch pipe 26 and the second branch pipe 27, and finally enter the interior of the sterilization box body 1 through the air inlet hole 32. After the high-temperature steam enters the sterilization box body 1, it first enters the air guide groove 31 in the air guide plate 3, and passes through the several air guide holes 33 opened on the air guide plate 3 from bottom to top, so as to realize the uniform diffusion of the high-temperature steam from bottom to top, and realize the disinfection of the items in the sterilization box body 1.

[0067] After completing the disinfection and sterilization of the items, select the limit block 72 on any side to drive the driving member 75 on the limit block 72 to move in the direction of approaching each other. At this time, the driving member 75 can drive the limit member 7 to move toward the accommodating hole 73, so that the limit member 7 re-enters the accommodating hole 73, and then the storage box 6 can be driven to move along the length direction of the guide block 71 on the support frame 5, so that the limit block 72 on the selected side enters the through groove 12. After that, the disassembly of the storage box 6 can be completed. After the storage box 6 is removed from the support frame 5, the silicone plug 67 can be opened to pour out the condensed water collected in the storage box 6.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
