Description

Technical Field

[0001] This invention relates to the field of dual-channel separate toilet technology, and more particularly to a dual-channel separate toilet for nuclear medicine and a radioactive waste liquid treatment system. Background Technology

[0002] Nuclear medicine is a medical technique that uses radioactive isotopes, beams, and nuclear radiation to treat lesions with concentrated irradiation. It has become an important treatment for diseases such as malignant tumors. Because nuclear medicine treatment uses nuclear radiation to irradiate diseased cells, the excrement of patients receiving treatment may contain radioactive materials. If not properly handled, this can easily cause radioactive contamination, endangering the safety of medical personnel and the surrounding environment. The existing device is based on the main body as the supporting structure. The water tank provides the flushing water source, and the cover and support plate provide protection and support during toileting. The overall structure is basically the same as that of an ordinary toilet. There is no special mechanism for separating urine and feces. Only a single sewage channel is set up. So when the patient uses the toilet, after flushing the water tank, the mixture of urine and feces carrying radioactivity is flushed into the single sewage channel and then transported to the underground decay pool for decay treatment before being discharged. The single-channel toilets currently used in hospitals have a single sewage discharge channel, which causes urine and feces to be mixed together and discharged into the decay tank when patients use them. This single-channel toilet makes it difficult to physically separate urine and feces at the source, resulting in non-radioactive feces and radioactive urine flowing together into the decay tank. This increases the total amount of radioactive waste liquid, greatly increases the pressure on the hospital's decay tank capacity, and significantly increases the treatment cost and radiation risk. Therefore, the above-mentioned technical problems need to be solved. Summary of the Invention

The water tank is fixed to one side of the upper end of the main body, the support plate is U-shaped and installed above the main body, and the cover plate is hinged to the upper part of the main body and adapted to the support plate. The main body is characterized in that: a separation mechanism for separating the urination and defecation areas is provided inside the main body, and a urination discharge channel and a defecation discharge channel are respectively opened on both sides of the bottom of the main body corresponding to the separation mechanism. The urination discharge channel and the defecation discharge channel both penetrate the bottom of the main body and extend to the outside of the main body. The main body is equipped with a risk analysis module, which is used to calculate the initial radioactivity concentration of the waste liquid and the real-time intensity of ultraviolet light, thereby determining the required irradiation time of ultraviolet light, and controlling the start and stop of ultraviolet light and the switching of the red and green warning lights on the water tank.

[0008] Preferably, an electromagnetic flow meter is fixedly installed on the urination and sewage discharge channel on the bottom surface of the main body, and the electromagnetic flow meter is sealed to the urination and sewage discharge channel.

[0009] Preferably, the separation plate is made of a radiation-resistant and corrosion-resistant material.

[0010] Preferably, the radioactive waste treatment system includes a risk analysis module; The risk analysis module calculates the mean and standard deviation of multiple data points acquired at the same time, removes outliers to obtain valid monitoring data, calculates the initial radioactivity concentration of the waste liquid by combining urine volume, flushing water volume and total radionuclide activity, and calculates the ultraviolet intensity in real time by taking into account factors such as aging, pollution, temperature, voltage and material transmittance decay of the ultraviolet lamp strip, derives the required irradiation time, and indicates the disinfection status through red and green warning lights.

[0011] Preferably, the analysis steps of the risk analysis module are as follows: M1: Calculates the mean and standard deviation of multiple data points acquired simultaneously using a multi-probe sensor, and obtains valid monitoring data after removing outliers; based on the measured urine volume... With flushing water volume Calculate the total volume of waste liquid And combined with the total activity of the radionuclides excreted this time Calculate the initial radioactivity concentration of the waste liquid ; M2: Real-time collection of cumulative usage time Surface pollutant accumulation Ambient temperature Power supply voltage Calculate the aging factor separately Pollutants Temperature Influence Factors Voltage factor and the material's violet transmittance attenuation factor And comprehensively calculate the real-time intensity of ultraviolet radiation. ; M3: According to the formula Calculate the UV lamp irradiation time required to reduce the radioactivity risk to a safe level. ,in denoted as the rate constant for the disinfection and purification of waste liquid containing radioactive nuclides by ultraviolet light.

Then turn off the red warning light and turn on the green warning light.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the cooperation of limiting blocks, separation plates and snap-fit ​​blocks, it is easy to accurately separate the urine and feces areas, improve the convenience and stability of separation operation, and thus achieve the functions of accurate classification and isolation of urine and feces and radiation protection. Furthermore, through the cooperation of the separation plate with urine discharge channels, feces discharge channels, cleaning nozzles and ultraviolet light strips, it is easy to realize classified transportation and classified decay treatment, improve the treatment efficiency of radioactive pollutants, prevent the discharge channel from being blocked and leaking, and thus achieve the functions of standardized treatment of urine and feces and ensure safe use. Ultimately, it solves the problem that the existing toilets with a single discharge channel cannot classify and treat excrement. 2. The risk analysis module calculates the total volume of waste liquid based on the urine volume measured by the electromagnetic flowmeter and the flushing water volume. Combined with the total activity of the nuclides in this discharge, the initial radioactivity concentration of the waste liquid is accurately determined, providing a scientific basis for the quantitative calculation of subsequent ultraviolet irradiation time. This overcomes the shortcomings of traditional toilets that cannot quantify the level of radioactive contamination. Taking into account the aging factor, contamination factor, temperature influence factor, voltage factor, and material transmittance decay factor of the ultraviolet lamp strip, the actual output intensity of ultraviolet light is calculated in real time, making the derivation of irradiation time more consistent with actual working conditions. This avoids insufficient disinfection or energy waste caused by ignoring environmental and device decay factors. Based on the real-time calculated required irradiation time, the working time of the ultraviolet lamp strip is automatically controlled, and the disinfection status is intuitively indicated by red and green warning lights. This allows medical staff and subsequent users to clearly judge the safe and usable status of the toilet, effectively reducing the risk of cross-infection and radioactive residue exposure in the nuclear medicine department.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: See Figures 1 to 6 A dual-channel separate toilet and radioactive waste treatment system for nuclear medicine includes a main body 1, a water tank 2, a cover plate 3, and a support plate 4. The water tank 2 is fixed to one side of the upper end of the main body 1. The support plate 4 is U-shaped and installed above the main body 1. The cover plate 3 is hinged to the upper part of the main body 1 and adapted to the support plate 4. The main body 1 has a separation mechanism inside for separating the urination and defecation areas. Urine discharge channels and defecation discharge channels are respectively opened on both sides of the bottom of the main body 1 corresponding to the separation mechanism. In use, the urine discharge channel uses an independent pipeline and is connected to the defecation discharge channel. The system is completely physically isolated and uses radiation-proof and corrosion-resistant materials to collect patients' radioactive urine and transport it to the subsequent decay treatment system. The fecal sewage channel uses an independent pipeline that is directly connected to the hospital's ordinary treatment tank for discharging non-radioactive feces, which do not enter the radioactive waste liquid treatment system. Both the urine and fecal sewage channels run through the bottom of the main body 1 and extend to the outside of the main body 1. Through the main body 1, water tank 2, cover plate 3, support plate 4, separation mechanism, and dual sewage outlet, it is easy to separate the urine and feces areas and complete the classified sewage discharge.

[0019] Reference Figures 3 to 4 As shown, the separation mechanism includes a limiting block 7, a separation plate 5, and a snap-fit ​​block 6. There are two limiting blocks 7, which are obliquely fixed to the inner walls on both sides of the main body 1. The separation plate 5 is inserted and installed between the two limiting blocks 7. Snap-fit ​​blocks 6 are fixed to both ends of the separation plate 5 at the limiting blocks 7. The snap-fit ​​blocks 6 engage with the limiting blocks 7. Through the limiting blocks 7, the separation plate 5, the snap-fit ​​blocks 6, and the inner walls of the main body 1, the separation plate 5 can be quickly snapped on to achieve separation of the urination and defecation areas.

[0020] Reference Figures 3 to 6 As shown, a cleaning nozzle 8 is installed at an angle on the inner wall of the main body 1 on one side of the separation plate 5. The pipe of the cleaning nozzle 8 passes through the inner wall of the main body 1 and is connected to the water tank 2. Through the cleaning nozzle 8, the main body 1, and the water tank 2, it is convenient to flush the inside of the toilet and keep it clean. A trapezoidal groove is opened on the main body 1, and a U-shaped installation tube 9 is fixedly installed in the trapezoidal groove. Through holes are opened at equal intervals near the inner side wall of the U-shaped installation tube 9, and an ultraviolet lamp strip 10 is installed on the inner side of the U-shaped installation tube 9 corresponding to the through holes. Multiple cleaning heads are fixedly connected at equal intervals at the bottom of the U-shaped installation tube 9. Through the trapezoidal groove, the U-shaped installation tube 9, the through holes, and the ultraviolet lamp strip 10, it is convenient to carry out ultraviolet sterilization and disinfection of the inside of the toilet.

[0021] Reference Figures 2 to 3As shown, an electromagnetic flow meter 11 is fixedly installed on the urination and sewage discharge channel on the bottom surface of the main body 1. The electromagnetic flow meter 11 is sealed to the urination and sewage discharge channel. Through the urination and sewage discharge channel and the electromagnetic flow meter 11, it is convenient to monitor the sewage flow and realize sewage data collection. The separation plate 5 is made of radiation-proof and corrosion-resistant material. The separation plate 5 made of radiation-proof and corrosion-resistant material is easy to adapt to the nuclear medicine department environment and extend its service life.

[0022] Working principle: When using this invention, the dual-channel separate toilet must first be installed in the designated toilet of the nuclear medicine department. After fixing the device, connecting the power supply and the pipeline, the electromagnetic flowmeter 11 fixedly installed on the urination channel at the bottom of the main body 1 is connected to the external dedicated pipeline. At the same time, the urination channel is connected to the pre-set radioactive waste liquid decay treatment system through the dedicated pipeline to ensure the sealing and dedicated nature of the urination channel. Meanwhile, the feces channel at the bottom of the main body 1 is directly connected to the ordinary sewage treatment tank in the hospital through an independent pipeline to achieve complete physical isolation between the urination channel and the feces channel, avoiding cross-contamination of radioactive materials. This is also the core design principle of the nuclear medicine department's special toilet for the treatment of radioactive excrement. That is, through the dual independent pipeline design, the urine containing radioactivity and the feces without radioactivity are treated separately, which reduces the risk of radioactive contamination and also reduces the load on the radioactive waste liquid treatment system. After the device is installed and debugged, when the patient uses it, first open the cover plate 3 and sit on the U-shaped support plate 4. At this time, the separation mechanism consisting of the limiting block 7, the separation plate 5 and the snap-fit ​​block 6 inside the main body 1 has been pre-installed. The separation plate 5 is snapped and fixed to the two limiting blocks 7 on both sides of the inner wall of the main body 1 by the snap-fit ​​blocks 6 at both ends. It is securely installed between the two limiting blocks 7, dividing the inside of the main body 1 into two independent areas, corresponding to the urination area and the defecation area respectively. Its separation principle is based on human usage habits and the direction of excretion. Through the blocking effect of the separation plate 5, the urine flows accurately into the urination area on one side and the feces fall into the defecation area on the other side, thereby achieving the initial physical separation of urine and feces. When a patient urinates, urine, guided by the separation plate 5, flows entirely into the urine discharge channel on the corresponding side of the bottom of the main body 1. From there, it is transported via the urine discharge channel and dedicated pipeline to the decay pool of the subsequent decay treatment system for radioactive decay treatment. Feces, on the other hand, fall into the area separated by the separation plate 5 and are directly discharged into the hospital's general treatment tank through the corresponding feces discharge channel at the bottom of the main body 1, without needing to enter the radioactive waste liquid treatment system. This dual-channel separation of wastewater discharge avoids cross-contamination between radioactive urine and non-radioactive feces at the source. Furthermore, the separation plate 5 is made of radiation-resistant and corrosion-resistant materials, making it suitable for the special needs of nuclear medicine departments. In special environments, it can effectively block the penetration of radioactive materials and extend the service life of the device. During the excretion process, the electromagnetic flowmeter 11 on the urination channel at the bottom of the main body 1 is always in working condition. Since the electromagnetic flowmeter 11 is sealed to the urination channel, it can monitor the flow of excrement in the urination channel in real time and accurately, and complete the collection and recording of flow data of radioactive urine samples from patients in the nuclear medicine department. This provides basic data support for subsequent radioactive waste treatment and patient condition monitoring. This design makes up for the inability of ordinary toilets to monitor the flow of radioactive excrement and is suitable for the clinical monitoring needs of the nuclear medicine department. After the patient finishes using the toilet, the cover 3 is closed, and the flushing program is started. At this time, the cleaning nozzle 8 (which is installed at an angle on the inner wall of the main body 1 on one side of the separation plate 5) connected to the water tank 2 draws water from the water tank 2 to perform directional flushing of the single-sided cavity separated by the separation plate 5 and the surface of the separation plate 5, ensuring that there is no excrement residue on the surface of the separation plate 5 and the urination area, and avoiding the adhesion of radioactive materials. At the same time, the U-shaped installation pipe 9 fixedly installed in the trapezoidal groove on the main body 1 works synchronously. Multiple cleaning heads fixed at equal intervals at the bottom of the U-shaped installation pipe 9 spray water synchronously to thoroughly flush the entire inner area of ​​the toilet, ensuring that there is no residual dirt in the defecation area and the inner wall of the main body 1. The wastewater generated by flushing flows into the corresponding urination and defecation channels and is discharged with the corresponding excrement, realizing the classified treatment of flushing wastewater and avoiding secondary pollution. After the toilet is flushed, the equidistant through holes inside the U-shaped installation tube 9 near the inner wall come into play. The ultraviolet light strip 10 installed on the inner side of the U-shaped installation tube 9 corresponding to the through holes is activated, emitting ultraviolet light through the through holes into the inner cavity of the toilet, the surface of the separation plate 5, and the two sewage outlets for full-area ultraviolet sterilization and disinfection. The principle is to use the bactericidal effect of ultraviolet light to kill the germs remaining inside the toilet, while reducing the risk of residual radionuclide contamination, ensuring that the inner cavity of the toilet is in a clean and safe state, providing protection for the next patient's use, and further reducing the hidden dangers of cross-infection and radioactive contamination in the nuclear medicine department. The entire workflow forms a closed loop of "installation and commissioning - separation and discharge - flow monitoring - directional + full-area flushing - ultraviolet disinfection", which not only meets the special treatment requirements of the nuclear medicine department for radioactive excrement, but also ensures the safety and hygiene of use.

[0023] Example 2: See Figure 7 The main body 1 is equipped with a risk analysis module; The risk analysis module uses a multi-probe sensor to calculate the mean and standard deviation of multiple data points acquired simultaneously, removing outliers to obtain valid monitoring data. It calculates the total volume of waste liquid based on the urine volume measured by the electromagnetic flowmeter and the flushing water volume, and combines this with the total activity of the excreted radionuclides to determine the initial radioactive concentration of the waste liquid. The module comprehensively considers the aging factor, contamination factor, temperature influence factor, voltage factor, and material transmittance decay factor of the ultraviolet lamp strip, calculates the ultraviolet intensity in real time, and then derives the ultraviolet lamp irradiation time required to reduce the radioactive risk to a safe level, alerting the user via red and green warning lights. A liquid level sensor is installed inside water tank 2 to monitor the liquid level data inside water tank 2; The sensor connects to itself Data is collected by each probe, through Multiple probes enable a single sensor to acquire data simultaneously. For each corresponding item, the acquired data is preprocessed; the collected data is sorted according to the collection time, and corresponding items collected at the same time are grouped together. averaging the data and standard deviation The calculation, and the mean obtained from the calculation. and standard deviation Collect data fluctuation range for corresponding items The system is configured to compare the collected data for a given item with its fluctuation range, mark data outside the fluctuation range as outliers, and record the number of outliers. ,like If the collected data is abnormal, the data will be re-tested; if If outliers are removed, the mean of the remaining corresponding test data after outlier removal is calculated.
