Abstract
Description
Technical Field
[0001] The utility model relates to a sterilization box, in particular to an endoscope sterilization box used for medical treatment. Background Art
[0002] As an indispensable medical device in modern medicine, medical endoscopes are widely used in various departments, including general surgery, urology, gastroenterology, and respiratory medicine. They can enter the body through natural orifices or surgically created channels, assisting doctors in disease screening, diagnosis, and minimally invasive surgery. However, because endoscopes come into direct contact with the patient's body fluids and tissues during use, their hygiene and sterilization are crucial.
[0003] Traditional endoscope sterilization methods primarily rely on pressure steam sterilization, hydrogen peroxide low-temperature plasma sterilization, and ethylene oxide sterilization. While effective, these methods often require cumbersome packaging and storage of endoscopes during the sterilization process to ensure they remain free of contamination. Furthermore, due to the unique material and structure of endoscopes, traditional packaging materials, such as paper and plastic bags, are easily scratched during the sterilization process, leading to secondary contamination of the medical device. Furthermore, endoscopes require regular leak testing, but this is not always performed during sterilization. This makes it very easy for endoscopes to leak, leading to cross-infection between patients. Utility Model Content

[0014] The beneficial effects of the utility model are:
[0015] 1. The utility model adopts a combination of a cleaning cabin and an equipment cabin, which solves the problem of cumbersome disinfection operations for daily use of endoscopes. When performing the disinfection operation, it is only necessary to place the endoscope in the cleaning cabin and engage the end of the endoscope rod on the flushing pipe. Subsequent inspection and cleaning can be carried out through the liquid level sensor controller to analyze the data and transmit the data to the controller, and then the controller operates the micromotor, liquid pump, liquid supply valve, disinfectant valve, water valve and drain valve to complete the automatic inspection and cleaning and disinfection operations, simplify the disinfection operation steps, and reduce the operator's operating time. At the same time, the airtightness of the endoscope will be tested before the disinfection operation, which effectively prevents the occurrence of cross-infection of pathogens between patients due to leakage of the endoscope.
[0016] 2. The utility model adopts a combination of a locking through hole, a limiting through hole and a flushing pipe arranged on the same axis, so that the endoscope can be erected relatively vertically in the utility model, which is convenient for subsequent inspection, cleaning and disinfection operations. At the same time, it ensures that the operator can accurately lock the endoscope rod on the flushing pipe when placing the endoscope, simplifying the operating steps, and preventing the endoscope rod from causing irreversible mechanical damage to the flushing pipe due to deviation in the placement position, effectively extending the service life of the flushing pipe, reducing the number of maintenance times and the use cost of the utility model, and indirectly improving the service life of the utility model.
[0017] 3. The utility model connects the water inlet end of the liquid suction pump to the disinfectant pipe with a disinfectant valve and the water inlet pipe with a water valve respectively, so that when the utility model is in use, the operator does not need to manually operate the disinfectant valve and the water valve to open and close to switch the cleaning and disinfection modes. The opening and closing of the disinfectant valve and the water valve can be completed by the controller to achieve the conversion between cleaning and disinfection, which simplifies the operating steps and solves the problem of ineffective disinfection of the endoscope due to the operator opening the wrong valve due to busy work. At the same time, it saves the operator's operating time and improves the practicality of the utility model.
[0018] 4. The utility model combines the first liquid level sensor, the second liquid level sensor, the third liquid level sensor, the liquid level sensor controller and the controller, so that when the endoscope is inspected, cleaned and disinfected, the liquid level information can be transmitted to the controller in a timely manner through the first liquid level sensor, the second liquid level sensor and the third liquid level sensor through the liquid level sensor controller, and then subsequent operations are performed through the controller to ensure that during inspection, the monitoring data of the first liquid level sensor and the third liquid level sensor can be used to analyze whether there is a dripping problem in the endoscope. At the same time, when performing disinfection, the monitoring data feedback of the second liquid level sensor is used to control the start and stop of the liquid pump through the controller, so that the disinfectant can immerse the endoscope and complete the disinfection work, reducing the operating steps of the operator and saving the operator's operating time, thereby effectively improving the work efficiency of endoscope disinfection.
[0019] 5. The utility model solves the problem that the water in the endoscope cavity flows back to the liquid pump, causing large errors in the detection results and misjudgment, due to the one-way valve that is locked at the connection between the flushing pipe and the connecting hose. This problem is solved by the one-way valve that is arranged at the connection between the flushing pipe and the connecting hose. At the same time, it prevents the backflow of sewage in the endoscope cavity from polluting the flushing pipe and the connecting hose, causing contamination to the endoscope during subsequent disinfection work.
[0020] 6. The utility model provides pads on both sides of the flushing pipe corresponding to the bottom wall of the cleaning chamber to ensure that the water and disinfectant solution in the endoscope cavity can be discharged quickly and timely after the inspection work is completed, thereby shortening the operation time of the utility model and improving the working efficiency of the utility model.

[0034] The specific working principle is:
[0035] The mirror rod tube mouth of the endoscope that needs to be cleaned is inserted through the engaging through-hole and the limiting through-hole to be engaged on the flushing pipe, and the micromotor is started through the controller. The micromotor drives the microscrew to rotate, and the microscrew drives the threaded lifting ring to move downward through rotation, and the pressure plate moves downward accordingly. The elastic seal is deformed by the clamping force between the bottom wall of the cleaning chamber and the pressure plate, so that the elastic seal fills the gap between the outer wall of the flushing pipe and the inner wall of the endoscope mirror rod. Then the liquid pump is started to inject water into the inner cavity of the endoscope mirror rod. After the mirror rod of the endoscope passes through the engaging through-hole on the first limiting fixing plate, the first limiting fixing plate forms a closed layer plate, which isolates the upper end space of the cleaning room from the lower end space. Two relatively closed spaces are formed, so when the first liquid level sensor sends a signal, the inner cavity of the endoscope is filled with aqueous solution and overflows to the drain port. At this time, the liquid pump is stopped, and the values of the first liquid level sensor and the third liquid level sensor are monitored at the same time; after standing for a certain period of time, when the first liquid level sensor has no water flow sensing, check whether the third liquid level sensor has water flow sensing during this period. If the third liquid level sensor has no water flow sensing, it means that the endoscope is completely sealed and there is no large water leakage; if the third liquid level sensor has water flow sensing during this period, it means that the endoscope is not completely sealed and there is a large water leakage. The controller sends an alarm through the alarm device. At this time, the operator needs to manually turn off the alarm device and The endoscope is inspected and repaired; when there is no major water leakage in the endoscope, the micro motor is started in reverse by the controller, and the lifting ring is driven upward by the micro screw to restore the elastic seal to its original shape. At this time, the water in the inner cavity of the endoscope rod flows into the cleaning chamber through the holes on the pad and is discharged through the drain pipe. After the aqueous solution is discharged, the drainage volume recorded by the third liquid level sensor is compared with the injected water volume (that is, the data counted by the flow meter minus the drainage volume counted by the first liquid level sensor, and the water volume in the diameter of the flushing pipe and the connecting hose at the rear end of the flow meter) to determine whether the endoscope has a minor water leakage; after the test is completed, the controller controls the opening of the liquid supply valve and the drain valve. The endoscope is cleaned. After cleaning and draining are completed, the controller controls the closing of the drain valve and the water valve, and at the same time starts the disinfectant valve to inject disinfectant into the cleaning chamber for immersion disinfection. Although the first limit fixing plate divides the cleaning chamber into two parts, the interior of the endoscope is a through structure, the disinfectant solution can flow through the endoscope rod to the cleaning chamber in the upper part. When the second liquid level sensor detects that the disinfectant is full of the cleaning chamber, the controller controls the closing of the upper liquid valve and the liquid pump, and the disinfection is allowed to stand. When the disinfection time is up, the controller controls the drain valve to discharge the disinfectant in the cleaning chamber to complete the disinfection operation of the endoscope. The operator can then take out the endoscope and dry it.
