Description

Technical Field

[0001] The invention belongs to the technical field of disinfection and sterilization of medical waste, and in particular relates to an autoclave disinfection and sterilization device for medical waste treatment. Background Art

[0002] Medical waste contains a variety of harmful pathogens, and its viruses and bacteria are the source of disease transmission. If medical waste is not properly disposed of, it may cause disease transmission. High-temperature steam sterilization refers to the wet heat treatment process that uses high-temperature steam to kill all microorganisms on the transmission medium. Medical waste is exposed to a water vapor atmosphere at a certain temperature and stays for a certain period of time. During this period, the latent heat released by the water vapor can cause protein denaturation and coagulation of pathogenic microorganisms in the medical waste, resulting in the death and decomposition of the pathogenic microorganisms, thereby rendering the medical waste harmless and achieving the purpose of safe disposal.

[0003] The autoclave equipment has high-temperature steam that interferes with vision during use, and the internal environment of the equipment is complex. The existing technology uses manual observation or adding cameras through transparent windows on the equipment, which cannot accurately grasp the number of bacterial colonies and cannot achieve online real-time detection and monitoring of the sterilization effect. It is necessary to open the autoclave equipment after the medical waste is treated, manually sample the treated medical waste, and take it to special equipment for testing. In addition, installing a transparent observation window on high-temperature and high-pressure equipment is costly, troublesome to maintain later, and there are also safety hazards.

[0004] According to the current existing technology, the following problems are found: Problem 1: During the sampling and testing process after autoclaving, the processed medical waste remains in the equipment and cannot be further processed, resulting in low efficiency of the entire process.

[0005] Question 2: If the medical waste autoclave equipment fails or there is a problem in the operation, and the incompletely disinfected medical waste is opened without online monitoring, the exposed bacteria and viruses will spread with the airflow, causing environmental pollution and personal infection, posing a great threat to personal safety. Summary of the invention

[0006] In view of this, the present invention proposes an autoclave disinfection and sterilization device for medical waste treatment, which can solve the problem that the current sampling, collection and detection process cannot further treat medical waste, and at the same time solve the problem that the sterilization and disinfection treatment process cannot be accurately judged.

[0007] The present invention is implemented as follows: The present invention provides an autoclave disinfection and sterilization device for medical waste treatment, comprising a shell, one side of which is connected to an air pump; the air pump is connected to an exhaust gas processor for treating chemical toxic gases generated inside the shell; the other side of the shell is connected to a steam generator for conveying high-temperature steam to the inside of the shell; A shooting detection component is fixedly installed on the top of the shell; a feeding component for conveying medical waste into the shell is also fixedly installed on one side of the shell; The shooting and detection assembly includes a mounting pipe; a high-speed microscope camera is fixedly mounted on the top of the mounting pipe; a reflector is fixedly mounted below the high-speed microscope camera; a light source is fixedly mounted on one side of the reflector; and a guide mirror is fixedly mounted below the reflector through a sealing plug; A liquid storage box for receiving condensed water vapor is fixedly installed on the upper part of the shell through a connecting rod; a light guide plate is fixedly installed on the bottom of the liquid storage box; the liquid storage box is located below the guide mirror; an opening is provided at the center position above the liquid storage box, and one end of the guide mirror close to the liquid storage box extends into the interior of the liquid storage box through the opening.

[0008] The technical effects of the autoclave disinfection and sterilization device for medical waste treatment provided by the present invention are as follows: by setting a shooting detection component, the autoclave disinfection state inside the equipment can be fed back to the control management center in real time, so that the entire process can be controlled at any time; by setting a reflector, the light emitted by the light source can be reflected into the inside of the liquid storage box to provide the light required for shooting with a high-speed microscope camera; by setting a guide mirror, one end of the guide mirror is extended into the condensed water vapor, and the state of microorganisms in the condensed water vapor is transmitted and amplified from the end of the guide mirror away from the high-speed microscope camera to the end of the guide mirror close to the high-speed microscope camera, thereby improving the imaging effect and making subsequent analysis and feedback more convenient; by setting a light guide plate, the light reflected by the reflector can be expanded to the entire liquid storage box; by setting a sealing plug, the shooting detection component can be separated from the high-temperature and high-pressure state inside the shell to avoid affecting the electronic equipment of the shooting detection component.

[0009] On the basis of the above technical solution, the autoclave disinfection and sterilization device for medical waste treatment of the present invention can also be improved as follows: Furthermore, the top of the shell has a distillation top, and the distillation top is in the shape of an inverted quadrangular pyramid; the top of the installation pipe is fixed to the distillation top by a connecting rod; the installation pipe passes through the bottom surface of the distillation top, and the outer wall of the installation pipe is connected to the bottom surface frame of the distillation top.

[0010] The beneficial effect of adopting the above further scheme is: by setting the distillation top as an inverted tetrahedron and connecting the distillation top with the outer wall of the installation pipe, the condensed water vapor generated during the steam pressing process can drip into the liquid storage box along the distillation top and the outer wall of the installation pipe.

[0011] Furthermore, the feed assembly includes a feed channel, which is fixedly mounted on the outer wall of the shell; a feed bin door is hingedly mounted on one side of the feed channel; and a pulverizer for pulverizing medical waste is also mounted on the other side of the feed channel.

[0012] Furthermore, a detection component for controlling the feeding stop is fixedly installed inside the shell; the detection component includes an adjustment slot and a laser sensor; there are multiple adjustment slots, which are fixedly installed on the four inner walls of the shell in a staggered manner; the laser sensor is installed on the adjustment slot in an up and down sliding manner.

[0013] The beneficial effects of adopting the above further scheme are: by setting the adjustment groove, the position of the laser sensor can be actively adjusted, thereby controlling the feed amount; by setting the laser sensor and the adjustment groove for staggered installation, the feed situation can be detected from multiple positions, thereby determining the feed amount more accurately.

[0014] Furthermore, a stirring assembly for stirring medical waste is fixedly installed inside the shell, and the stirring assembly includes a stirring rod and a stirring motor, and the stirring motor is fixedly installed on the outer wall of the shell; the output shaft of the stirring motor passes through the outer wall of the shell and is fixedly connected to one end of the stirring rod through a coupling; the other end of the stirring rod is rotatably mounted on the inner wall of the shell through a bearing; and the connection position between the output shaft of the stirring motor and the shell is sealed.

[0015] Furthermore, the lens of the high-speed microscope camera passes through the reflector.

[0016] The beneficial effects of adopting the above further scheme are: by setting the lens of the high-speed microscope camera to pass through the reflector, the light emitted by the light source is prevented from affecting the imaging of the high-speed microscope camera; in order to ensure the reflection efficiency of the reflector, the back of the reflector is made of highly reflective material, so the lens of the high-speed microscope camera is set to pass through the reflector to avoid the high-reflective material on the back of the reflector affecting the shooting of the high-speed microscope camera.

[0017] Furthermore, a plurality of small holes are distributed on the side walls of the liquid storage box near the bottom, and the diameters of the small holes are all between 0.2-0.5 mm.

[0018] The beneficial effect of adopting the above further scheme is: by setting small holes on the liquid storage box, the condensed water vapor in the liquid storage box can seep out from the small holes, ensuring that the condensed water vapor inside the liquid storage box is in a flowing state, avoiding the same pictures taken by the high-speed microscope camera in different time periods, thereby affecting subsequent analysis and judgment.

[0019] Furthermore, a discharge bin door for discharging medical waste is rotatably installed at the bottom of the shell body through a hinge. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Optionally, in the above technical solution, a plurality of small holes are distributed on the side walls around the bottom of the liquid storage box 27 , the apertures of the small holes are all between 0.2-0.5 mm, and all the small holes are located on the light guide plate 28 .

[0030] Optionally, in the above technical solution, a discharge bin door 12 for discharging medical waste is also rotatably mounted on the bottom of the shell 10 via a hinge.

[0031] Optionally, in the above technical solution, a heat pipe for heating medical waste is provided at the bottom of the shell 10 .

[0032] Optionally, in the above technical solution, a bracket is welded and fixed to the bottom of the shell 10.

[0033] The specific process and principle of the present invention are as follows: Collect the medical waste, open the feed bin door 32, and feed the collected waste into the system through the feed channel 31; Under the action of gravity, the waste falls along the feed channel 31 to the crusher 33, where the waste is crushed by the crusher 33 and sent into the housing 10; As the amount of waste increases, it accumulates inside the housing 10 and the height gradually increases until the four intersections formed by the four laser sensors 342 are blocked. At this time, the feed bin door 32 is closed, and the medical waste is stopped from being transported into the housing 10. At this time, the interior of the shell 10 is ready, and the steam generator 40 passes high-temperature steam into the shell 10 through the pipeline to sterilize and disinfect the crushed medical waste. At the same time, the stirring motor 72 drives the stirring rod 71 to stir the medical waste accumulated in the shell 10 so that it can be fully sterilized and disinfected by the high-temperature steam. The high-temperature steam inside the shell 10 floats up with the microorganisms inside the shell 10, and condenses at the distillation top 11 on the top of the shell 10; due to the special inverted quadrangular pyramid shape of the distillation top 11 on the top of the shell 10, the condensate carrying the microorganisms slides down along the distillation top 11 to the outer wall of the installation pipe 21 after condensation, and drips along the outer wall of the installation pipe 21 into the liquid storage box 27; There are small holes on the side wall of the liquid storage box 27 near the bottom. After a period of accumulation, the condensed liquid entering the liquid storage box 27 will overflow through the small holes on the side wall of the liquid storage box 27. The more condensed liquid in the liquid storage box 27, the faster the overflow speed. In this way, the condensed liquid in the liquid storage box 27 is always in a flowing state, and when the storage volume reaches a certain level, the dripping amount and the overflowing amount reach a balance. During the high-temperature disinfection and sterilization process, the air pump 50 is started at regular intervals to introduce harmful gases inside the housing 10 into the exhaust gas processor 60; After a period of high-temperature sterilization (the time is determined according to the amount of medical waste to be processed, and the larger the amount of medical waste to be processed, the longer the time), the light source 24 is started to emit illumination light, which is reflected by the reflector 23 to the bottom of the liquid storage box 27 and diffused by the light guide plate 28 to the entire liquid storage box 27, illuminating the condensate. The guide mirror 25 images the scene inside the liquid storage box 27 from the end far from the high-speed microscope camera 22 to the end close to the high-speed microscope camera 22. The high-speed microscope camera 22 takes a photo and uploads it to the background terminal. The technician analyzes the types of microorganisms in the photo to determine whether the high-temperature sterilization needs to be continued. After the high-temperature disinfection and sterilization is completed, the discharge bin door 12 at the bottom of the shell 10 is opened to take out the waste from the shell 10 .

[0034] The present invention avoids starting the autoclave equipment for sampling to determine the autoclave treatment process, and instead uses the microbial status to reflect indirectly. The entire autoclave treatment process will not be affected during the detection process, which greatly ensures the safety of technicians.

[0035] The above description is only a preferred embodiment of the present invention and is 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.
