Description

Technical Field

[0001] The invention relates to the technical field of sterilization effect detection equipment, in particular to an ethylene oxide sterilization effect detection device. Background Art

[0002] The ethylene oxide sterilization effect detection device is mainly used to verify whether the sterilization effect of ethylene oxide (EO) sterilization process meets the requirements. Its working principle generally includes the following steps: Sample placement: Place the sterilized sample to be tested in a specific container or carrier to ensure that the sample can represent the actual sterilized items, and use a specific method to extract the residual ethylene oxide from the sample. Common detection methods include gas chromatography and high-performance liquid chromatography. These methods can be used to analyze the extracted samples to determine the concentration of residual ethylene oxide, compare the test results with relevant standards or regulations, and determine whether the residual ethylene oxide is within the allowable range. According to the test results, evaluate whether the effect of ethylene oxide sterilization meets the specified requirements, so as to verify the effectiveness of ethylene oxide sterilization.

[0003] The traditional detection method usually involves culturing the specimen and then observing the color change of the biological indicator with the naked eye. The culturing time for detecting bacteria using this method is relatively long. In addition, when the specimen is taken out of the sterilization device, the specimen may be affected by the external environment, and airborne bacteria may adhere to the outer wall of the specimen, seriously affecting the detection effect of the specimen. In response to the above problems, the following solutions are proposed. Summary of the invention

The mechanism provides an installation position for subsequent mechanisms, which plays a stabilizing effect during operation, ensures the normal operation of the equipment, and avoids problems such as bumps;

[0005] The pulling mechanism includes a pulling shell fixedly connected to the inner wall of the through hole on the side wall of the equipment shell, a feeding port is opened on the top of the pulling shell, and a sliding door is slidably connected inside the feeding port;

[0006] The cleaning mechanism includes a sliding tube slidably connected to the inner wall of the mounting hole, a water outlet trough 1 is provided on the side wall of the sliding tube, a sprinkler is fixedly connected to the bottom of the air pressure plate, and a reset spring 1 is sleeved on the outer wall of the sliding tube 1. The reset spring 1 provides pressure for the sliding tube 1 during operation and provides mechanical power for subsequent reset.

[0007] Preferably, the detection mechanism also includes an infrared spectrometer fixedly connected to the bottom of the air pressure plate, a scraper is fixedly connected to the top of the air pressure plate, and a baffle is fixedly connected to the side wall of the air pressure plate. The present invention is internally provided with an equipment housing, a pulling housing, a scraper, and a baffle. The baffle is closely fitted to the equipment housing, thereby increasing the sanitary environment of the equipment before the equipment is operated.

[0008] Preferably, the detection mechanism also includes a mounting groove provided on the top of the device housing, a collecting plate is fixedly connected to the bottom of the device housing, and a water outlet is provided at the bottom of the collecting plate.

[0009] Preferably, the pulling mechanism also includes an airbag fixedly connected to the bottom of the sliding door, a fixed plate is fixedly connected to the inner wall of the pulling shell, a plurality of limiting columns are fixedly connected to the inner wall of the pulling shell, the outer wall of the limiting column is slidably connected to the outer wall of the pulling spring, and a plurality of pulling springs are fixedly connected to the side wall of the fixed plate. The air pressure plate is driven upward by an electric telescopic rod to form a negative pressure on the inner wall of the equipment shell and the bottom of the air pressure plate. At this time, the airbag inside the sliding door is deformed by the negative pressure and fits into the gap between the sliding door and the feed port to improve the sealing effect of the equipment. In addition, bacterial detection under a negative pressure environment can ensure the physical isolation between the sample and the operator, and prevent the leakage of ethylene oxide gas from causing harm to the staff.

[0010] Preferably, the pulling mechanism also includes a rolling plate fixedly connected to the end of the pulling spring away from the fixed plate, the end of the rolling plate away from the pulling spring is fixedly connected to a pulling belt, the end of the pulling belt away from the rolling plate is fixedly connected to the bottom of the air pressure plate, and a rotating column is rotatably connected to the inner wall of the equipment shell, and the outer wall of the rotating column is rotatably connected to the outer wall of the pulling belt. Before use, the object to be inspected is placed on the upper end of the rolling plate, and the sliding door is closed, and the power of the electric telescopic rod is turned on. At this time, the electric telescopic rod will drive the air pressure plate to move upward. At this time, the air pressure plate drives one end of the pulling belt to move upward, and drives the rolling plate to move toward the center of the equipment through the pulling belt. Subsequently, the absorption characteristics of the sample in the infrared region are measured by an infrared spectrometer. Through comparison and quantitative analysis, the sterilization effect and the concentration of residual ethylene oxide can be detected. Before the baffle moves upward, the baffle will block the side through hole of the equipment shell. The above method reduces the contact between the inside of the equipment and the external environment, and avoids the influence of the air environment on the detection effect.

[0011] Preferably, the cleaning mechanism also includes a water tank fixedly connected to the inner wall of the mounting groove, and a water pipe is connected through the outer wall of the water tank, a sliding pipe 2 is slidably connected to the inner wall of the through hole in the water tank, a water outlet groove 2 is opened at the outer wall of the sliding pipe 2, and the end of the sliding pipe 2 away from the water tank is fixedly connected to the water outlet pipe, and a reset spring 2 is sleeved on the outer wall of the water outlet groove 2. Utilizing the negative pressure generated by the above, during the upward movement of the air pressure plate, the top of the sliding pipe 1 will contact the bottom of the water outlet pipe. As the electric telescopic rod is continuously raised, the pressure generated will exceed the limits of the reset spring 2 and the reset spring 1, forcing the sliding pipe 1 and the sliding pipe 2 to move. At this time, the liquid inside the water tank passes through the water outlet groove 2 along the water outlet pipe and the sliding pipe 1 to reach the sprinkler. At this time, the negative pressure at the bottom of the air pressure plate will draw out disinfected water and sandblast on the inner wall of the equipment casing to clean the inside of the equipment, thereby avoiding the growth of miscellaneous bacteria inside the equipment and affecting the efficiency of subsequent detection.

[0012] Preferably, the cleaning mechanism also includes a sewage pipe fixedly connected to the bottom of the collecting plate, a fixing frame fixedly connected to the inner wall of the sewage pipe, and a hydraulic pipe fixedly connected to the outer wall of the fixing frame.

[0013] Preferably, the cleaning mechanism also includes a baffle fixedly connected to the end of the hydraulic pipe away from the fixed frame, a return spring three is sleeved on the outer wall of the hydraulic pipe, a water outlet plate is fixedly connected to the top of the baffle, the outer wall of the water outlet plate is slidably connected to the inner wall of the limiting block, and after the air pressure plate reaches the highest position, the disinfectant is pumped into the interior of the equipment in the above manner. At this time, the negative pressure inside the equipment casing will be converted into normal air pressure, and as the electric telescopic rod drives the air pressure plate to move downward, the bottom of the air pressure plate is converted from normal air pressure to high pressure. At this time, the high-pressure gas will act on the surface of the baffle, and force the baffle to move, and squeeze the hydraulic pipe to move downward. At this time, the baffle will detach from the inner wall of the limiting block, and the internal mixed liquid will be discharged outward through the pipeline composed of the limiting block and the water outlet plate, thereby realizing the discharge of sewage.

[0014] The present invention has the following beneficial effects:

[0015] (1) Before use, the present invention places the object to be tested on the upper end of the rolling plate, closes the sliding door, and turns on the power of the electric telescopic rod. At this time, the electric telescopic rod will drive the air pressure plate to move upward, and the air pressure plate will drive one end of the pulling belt to move upward, and the rolling plate will move toward the center of the equipment through the pulling belt. Then, the absorption characteristics of the sample in the infrared region are measured by an infrared spectrometer. Through comparison and quantitative analysis, the sterilization effect and the concentration of residual ethylene oxide can be detected. Before the baffle moves upward, the baffle will block the side through-hole of the equipment housing. In this way, the contact between the inside of the equipment and the external environment is reduced, and the air environment is prevented from affecting the detection effect.

[0016] (2) The present invention drives the air pressure plate to move upward through the electric telescopic rod, so that negative pressure is formed on the inner wall of the equipment shell and the bottom of the air pressure plate. At this time, the air bag inside the sliding door is deformed by the negative pressure and fits into the gap between the sliding door and the feed inlet, thereby improving the sealing effect of the equipment. In addition, bacterial detection is performed under a negative pressure environment to ensure physical isolation between the sample and the operator, thereby preventing the leakage of ethylene oxide gas from causing harm to the staff.

[0017] (3) The present invention utilizes the negative pressure generated above. During the upward movement of the air pressure plate, the top of the sliding tube 1 will contact the bottom of the water outlet pipe. As the electric telescopic rod is continuously raised, the pressure generated will exceed the limit of the return spring 2 and the return spring 1, forcing the sliding tube 1 and the sliding tube 2 to move. At this time, the liquid inside the water tank passes through the water outlet trough 2 along the water outlet pipe and the sliding tube 1 to reach the sprinkler. At this time, the negative pressure at the bottom of the air pressure plate will draw out disinfected water and blast sand on the inner wall of the device casing to clean the inside of the device, thereby preventing the growth of miscellaneous bacteria inside the device and affecting the efficiency of subsequent detection.

[0018] (4) In the present invention, after the air pressure plate reaches the highest position, the disinfectant is pumped into the interior of the device in the above-mentioned manner. At this time, the negative pressure inside the device casing will be converted into normal air pressure, and as the electric telescopic rod drives the air pressure plate to move downward, the bottom of the air pressure plate will be converted from normal air pressure to high pressure. At this time, the high-pressure gas will act on the surface of the blocking plate, forcing the blocking plate to move and squeezing the hydraulic pipe to move downward. At this time, the blocking plate will detach from the inner wall of the limiting block. At this time, the internal mixed liquid will be discharged outward through the pipeline composed of the limiting block and the water outlet plate, thereby realizing the discharge of sewage.

[0041] A specific application of this embodiment is: before use, the present invention places the object to be inspected on the upper end of the rolling plate 208, closes the sliding door 203, and turns on the power of the electric telescopic rod 102. At this time, the electric telescopic rod 102 will drive the air pressure plate 103 to move upward. At this time, the air pressure plate 103 drives one end of the pulling belt 209 to move upward, and drives the rolling plate 208 to move toward the center of the equipment through the pulling belt 209. Then, the absorption characteristics of the sample in the infrared region are measured by the infrared spectrometer 105.

At this time, the air bag 204 inside the sliding door 203 is deformed by the negative pressure and fits into the gap between the sliding door 203 and the feed inlet 202. By utilizing the negative pressure generated above, during the upward movement of the air pressure plate 103, the top of the sliding tube 1 301 will contact the bottom of the water outlet pipe 309. As the electric telescopic rod 102 is continuously raised, the pressure generated will exceed the limits of the return spring 2 310 and the return spring 1 304, forcing the sliding tube 1 301 and the sliding tube 2 307 to move. At this time, the liquid in the water tank 305 flows through the water outlet trough 2 308 along the water outlet pipe 309 and the sliding tube 1 301 reaches the sprinkler 303, at which time the negative pressure at the bottom of the air pressure plate 103 will draw out the disinfectant and spray it on the inner wall of the equipment housing 101. After the air pressure plate 103 reaches the highest position, since the disinfectant is drawn into the equipment in the above manner, the negative pressure inside the equipment housing 101 will be converted into normal air pressure, and as the electric telescopic rod 102 drives the air pressure plate 103 to move downward, the bottom of the air pressure plate 103 is converted from normal air pressure to high pressure.
