Description

Technical Field

[0001] The present invention relates to the technical field of peritoneal dialysis fluid exchange, and in particular to an environment monitoring method and device for peritoneal dialysis fluid exchange. Background Art

[0002] Peritoneal dialysis is the main alternative treatment for end-stage renal failure. It uses the patient's own peritoneum as a semipermeable membrane and injects peritoneal dialysis fluid into the abdominal cavity to achieve solute exchange between the blood and the peritoneal dialysis fluid, remove metabolic waste in the blood, maintain the body's electrolyte and acid-base balance, and remove excess fluid. Peritoneal dialysis patients need to perform such fluid changes frequently. However, during peritoneal dialysis fluid changes, once bacteria in the air enter the abdominal cavity, they will infect the patient and cause an inflammatory reaction, which is tantamount to adding insult to injury for peritoneal dialysis patients. Therefore, it is very important to reduce the bacterial growth in the fluid change environment and reduce the potential hidden dangers of the fluid change environment to peritoneal dialysis fluid changes.

[0003] The indoor parameter regulating equipment in the prior art usually monitors the indoor temperature or humidity in real time, and then when the temperature or humidity exceeds a threshold, immediately controls the air conditioner and other equipment to adjust the indoor temperature or humidity. For example, the patent "An indoor environment monitoring system and its monitoring method" (publication (announcement) number: CN103557579A) collects indoor air quality data through an air environment detection collector, and then automatically adjusts the air quality in real time through air conditioning, etc. Such an environmental monitoring system is suitable for ordinary families, but not for peritoneal dialysis exchange rooms. Because during the patient's peritoneal dialysis exchange process and before the start of peritoneal dialysis exchange, turning on regulating equipment such as air conditioners or fans will increase the chance of infection. Therefore, there is an urgent need for an environmental monitoring method specifically for peritoneal dialysis exchange rooms to reduce the probability of infection, especially for less professional home exchange patients, and an environmental monitoring method specifically for peritoneal dialysis exchange rooms is even more needed. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention proposes an environmental monitoring method and device for peritoneal dialysis fluid exchange, which reduces the probability of infection in peritoneal dialysis patients during fluid exchange operations.

[0005] In a first aspect, the present invention provides an environmental monitoring method for peritoneal dialysis fluid exchange.

[0006] In a first possible implementation, a method for monitoring the environment of peritoneal dialysis fluid exchange includes:

[0007] Obtain the peritoneal dialysis fluid exchange time and determine the environmental adjustment time based on the peritoneal dialysis fluid exchange time;

[0008] During the environmental adjustment time, current environmental parameters are obtained, including current environmental temperature, current environmental humidity, and current environmental dust concentration, and parameters of the peritoneal dialysis fluid exchange chamber are adjusted according to the current environmental temperature, current environmental humidity, and current environmental dust concentration; and after the first preset time period of the environmental adjustment time ends, the peritoneal dialysis fluid exchange time begins;

[0009] During the peritoneal dialysis fluid exchange time, the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration in the peritoneal dialysis fluid exchange room are obtained, and step-by-step early warning and protection are carried out based on the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration.

[0010] In combination with the first possible implementation, in a second possible implementation, determining the environmental adjustment time according to the peritoneal dialysis fluid exchange time includes:

[0011] Determine the start time of peritoneal dialysis fluid exchange according to the peritoneal dialysis fluid exchange time;

[0012] Determining the end time of environmental adjustment according to the first preset time period and the start time of peritoneal dialysis fluid exchange;

[0013] The start time of the environmental adjustment is determined according to the end time of the environmental adjustment and the second preset time period.

[0014] In combination with the first possible implementation, in a third possible implementation, parameters of the peritoneal dialysis fluid exchange chamber are adjusted according to the current ambient temperature, the current ambient humidity, and the current ambient dust concentration, including:

[0015] Compare the current ambient temperature with the first temperature threshold and the second temperature threshold respectively to obtain a temperature comparison result, and adjust the temperature according to the temperature comparison result;

[0016] Compare the current ambient humidity with the first humidity threshold and the second humidity threshold respectively to obtain a humidity comparison result, and adjust the humidity according to the humidity comparison result;

[0017] The current ambient dust concentration is compared with a preset dust concentration threshold. If the current ambient dust concentration is greater than the preset dust concentration threshold, the air purifier is triggered to turn on.

[0018] In combination with the third implementable manner, in a fourth implementable manner, temperature adjustment is performed according to the temperature comparison result, including:

[0019] When the current ambient temperature is lower than the first temperature threshold, the air conditioner is triggered to start the heating mode and raise the current ambient temperature to the third temperature threshold within the ambient adjustment time;

[0020] When the current ambient temperature is greater than the second temperature threshold, the air conditioner is triggered to start the cooling mode, and the current ambient temperature is reduced to the fourth temperature threshold within the environmental adjustment time; the fourth temperature threshold < the first temperature threshold < the second temperature threshold < the third temperature threshold.

[0021] In combination with the third implementable manner, in a fifth implementable manner, humidity adjustment is performed according to the humidity comparison result, including:

[0022] When the current ambient humidity is lower than the first humidity threshold, the humidifier is triggered to turn on, and the current ambient humidity is raised to the third humidity threshold within the ambient adjustment time;

[0023] When the current ambient humidity is greater than the second humidity threshold, the dehumidifier is triggered to turn on and the current ambient humidity is reduced to the fourth humidity threshold within the ambient adjustment time; the fourth humidity threshold < the first humidity threshold < the second humidity threshold < the third humidity threshold.

[0024] In combination with the first possible implementation, in the sixth possible implementation, step-by-step early warning protection is performed based on real-time temperature, real-time humidity, real-time dust concentration, and real-time oxygen concentration, including:

[0025] When one or more of the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration is within the first-level warning range, the environmental data within the first-level warning range will be displayed in red on the preset display screen;

[0026] When multiple of the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration are within the second-level warning range, the alarm is triggered to sound three alarms, and the environmental data within the second-level warning range is displayed in red on the preset display screen;

[0027] When the real-time dust concentration and the real-time oxygen concentration are within the third-level warning range, the alarm is triggered to emit a continuous alarm sound, and the real-time dust concentration and the real-time oxygen concentration are displayed in red on the preset display screen.

[0028] In a second aspect, the present invention provides an environmental monitoring device for peritoneal dialysis fluid exchange.

[0029] In a seventh possible implementation, an environmental monitoring device for peritoneal dialysis fluid exchange is based on the above-mentioned environmental monitoring method for peritoneal dialysis fluid exchange, and includes a square outer shell and an inner cavity; a plurality of display screens are provided on one side of the square outer shell, and a support plate is provided on the other side of the square outer shell; a controller, an alarm, a temperature and humidity sensor, a dust sensor, and an oxygen concentration sensor are provided in the inner cavity; the controller is respectively connected to the alarm, the temperature and humidity sensor, the dust sensor, the oxygen concentration sensor and each display screen.

[0030] In combination with the seventh possible implementation method, in the eighth possible implementation method, the controller is used to receive environmental parameters collected by the temperature and humidity sensors, dust sensors and oxygen concentration sensors, send each environmental parameter to each display screen for display, and adjust the peritoneal dialysis fluid exchange chamber according to the current environmental parameters within the environmental adjustment time. It is also used to perform step-by-step early warning and protection according to real-time environmental parameters during the peritoneal dialysis fluid exchange time.

[0031] In combination with the seventh possible implementation method, in the ninth possible implementation method, the connection end of the support plate is set at the edge of the square shell, and the free end of the support plate is set with a hole; the hook on the wall is passed through the hole of the support plate, and the environmental monitoring equipment is fixed on the wall, and forms a V shape with the wall.

[0032] In combination with the seventh possible implementation method, in the tenth possible implementation method, an environmental monitoring device for peritoneal dialysis fluid exchange includes a host computer and a camera. The host computer is communicatively connected to a controller for receiving current environmental parameters sent by the controller and adjusting the peritoneal dialysis fluid exchange chamber according to the current environmental parameters; the camera is arranged at the top of the square shell, and the controller controls the camera to photograph the peritoneal dialysis fluid exchange chamber during the peritoneal dialysis fluid exchange time.

[0033] It can be seen from the above technical solution that the beneficial technical effects of the present invention are as follows:

[0034] 1. Determine the environmental adjustment time based on the peritoneal dialysis fluid exchange time, adjust the environmental parameters of the peritoneal dialysis fluid exchange chamber during the environmental adjustment time, and enter the peritoneal dialysis fluid exchange time after the environmental parameter adjustment is completed. In this way, the environmental adjustment time is determined according to the peritoneal dialysis fluid exchange time, and the environmental parameters are adjusted before the peritoneal dialysis fluid exchange begins. After a period of time after the adjustment time, the peritoneal dialysis fluid exchange begins. Compared with adjusting the environmental parameters directly during the peritoneal dialysis fluid exchange time or starting the peritoneal dialysis fluid exchange immediately after the environmental parameter adjustment, this reduces the probability of infection during the fluid exchange operation for the patient, thereby reducing the negative impact of the fluid exchange environment on the health of the peritoneal dialysis patient.

[0035] 2. During the peritoneal dialysis fluid exchange process, the temperature, humidity, dust, and oxygen concentration in the peritoneal dialysis fluid exchange room are monitored in real time, and step-by-step early warning and protection are carried out, which is conducive to patients taking rescue measures in time, greatly reducing the bacterial infection and other negative effects on the body caused by the environment when patients are changing fluids at home, and solving the hidden dangers of the home fluid exchange environment to peritoneal dialysis fluid exchange operations.

[0045] Combine Figure 1As shown, this embodiment provides an environmental monitoring method for peritoneal dialysis fluid exchange, comprising:

[0046] Step S01, obtaining the peritoneal dialysis fluid exchange time, and determining the environment adjustment time according to the peritoneal dialysis fluid exchange time;

[0047] Step S02: During the environmental adjustment time, current environmental parameters are obtained, including current environmental temperature, current environmental humidity, and current environmental dust concentration; parameters of the peritoneal dialysis fluid exchange chamber are adjusted according to the current environmental temperature, current environmental humidity, and current environmental dust concentration; and after the first preset time period of the environmental adjustment time ends, the peritoneal dialysis fluid exchange time begins;

[0048] Step S03: During the peritoneal dialysis fluid exchange time, the real-time temperature, real-time humidity, real-time dust concentration, and real-time oxygen concentration in the peritoneal dialysis fluid exchange room are obtained, and step-by-step early warning and protection are performed based on the real-time temperature, real-time humidity, real-time dust concentration, and real-time oxygen concentration.

[0049] Optionally, determining the environmental adjustment time according to the peritoneal dialysis fluid exchange time includes: determining the start time of the peritoneal dialysis fluid exchange according to the peritoneal dialysis fluid exchange time; determining the end time of the environmental adjustment according to the first preset time period and the start time of the peritoneal dialysis fluid exchange; determining the start time of the environmental adjustment according to the end time of the environmental adjustment and the second preset time period.

[0050] Optionally, 30 minutes ≤ first preset time period ≤ 60 minutes, 5 minutes ≤ second preset time period ≤ 20 minutes. In some embodiments, when the peritoneal dialysis fluid exchange time is from 10:00 to 10:30, the peritoneal dialysis fluid exchange start time is determined to be 10:00, and when the first preset time period is 30 minutes, the end time of the environmental adjustment is determined to be 30 minutes before 10:00, that is, the end time of the environmental adjustment is 9:30. When the second preset time period is 5 minutes, the start time of the environmental adjustment is determined to be 5 minutes before the end time, that is, the start time of the environmental adjustment is 9:25. Then, when the peritoneal dialysis fluid exchange time starts at 10:00, the temperature, humidity and dust concentration of the peritoneal dialysis fluid exchange chamber are adjusted between 9:25 and 9:30.

[0051] In some embodiments, the environmental parameters are adjusted half an hour to one hour before the start of peritoneal dialysis fluid exchange. The peritoneal dialysis fluid exchange is carried out during a period of time after the adjustment time. Compared with adjusting the environmental parameters directly during the peritoneal dialysis fluid exchange time or starting the peritoneal dialysis fluid exchange immediately after the environmental parameters are adjusted, the probability of infection of the environment on the patient undergoing fluid exchange is reduced, and the negative impact of the environment on the fluid exchange operation is reduced.

[0052] Optionally, parameters of the peritoneal dialysis fluid exchange chamber are adjusted according to the current ambient temperature, current ambient humidity and current ambient dust concentration, including: comparing the current ambient temperature with the first temperature threshold and the second temperature threshold respectively to obtain a temperature comparison result, and adjusting the temperature according to the temperature comparison result; comparing the current ambient humidity with the first humidity threshold and the second humidity threshold respectively to obtain a humidity comparison result, and adjusting the humidity according to the humidity comparison result; comparing the current ambient dust concentration with a preset dust concentration threshold, and triggering the air purifier to turn on when the current ambient dust concentration is greater than the preset dust concentration threshold.

[0053] In some embodiments, peritoneal dialysis patients require frequent fluid changes, and an excessive presence of bacteria in the environment can easily lead to bacterial infection. For example, in the summer, the ambient temperature in the peritoneal dialysis fluid exchange room is particularly high. However, if the air conditioner is turned on during the fluid exchange process, dust in the air will fly everywhere, increasing the risk of infection for the patient. Therefore, in this embodiment, the air conditioner is turned on one to half an hour before the fluid exchange to cool the room to a suitable temperature, providing a comfortable temperature environment for the patient while reducing the risk of bacterial infection.

[0054] Optionally, temperature adjustment is performed based on the temperature comparison result, including: when the current ambient temperature is lower than the first temperature threshold, triggering the air conditioner to start the heating mode, and raising the current ambient temperature to a third temperature threshold within the ambient adjustment time; when the current ambient temperature is higher than the second temperature threshold, triggering the air conditioner to start the cooling mode, and lowering the current ambient temperature to a fourth temperature threshold within the ambient adjustment time; the fourth temperature threshold < the first temperature threshold < the second temperature threshold < the third temperature threshold.

[0055] Optionally, the first temperature threshold is 25 degrees and the second temperature threshold is 28 degrees. In some embodiments, when the temperature is too high in the summer, the current temperature is far above 28 degrees, indicating that the indoor temperature rises quickly, so the indoor temperature parameter is adjusted to a fourth temperature threshold, which is far below the standard temperature range of 25-28 degrees. In this way, during the period from the end of the environmental adjustment time to the start of peritoneal dialysis fluid exchange, the indoor temperature begins to rise again, also starting from the fourth temperature threshold. By the time the peritoneal dialysis fluid exchange starts, the peritoneal dialysis fluid exchange room can still provide a more comfortable temperature for the patient. Conversely, in the winter, when the temperature is too low, the current temperature is far below 25 degrees, indicating that the indoor temperature drops quickly, so the indoor temperature parameter is adjusted to a third temperature threshold, which is far greater than the second temperature threshold. In this way, when the peritoneal dialysis fluid exchange starts, the temperature in the peritoneal dialysis fluid exchange room can meet the patient's fluid exchange conditions.

[0056] Optionally, performing temperature adjustment according to the temperature comparison result further includes: obtaining a temperature change rate of the peritoneal dialysis fluid exchange chamber according to the current ambient temperature, and determining a first temperature threshold or a fourth temperature threshold according to the temperature change rate of the peritoneal dialysis fluid exchange chamber.

[0057] Optionally, the current ambient temperature and current climate data are obtained, and the historical climate of the same geographical location as the current climate is searched in the network database to obtain the indoor temperature changes of the same historical climate in the same period, and the temperature change rate of the peritoneal dialysis exchange room is determined based on the found indoor temperature changes.

[0058] In some embodiments, based on the current ambient temperature and current climate data, the indoor temperature change for the same geographical location and historical climate is: a 10-degree increase between 9:30 and 10:00. The fourth temperature threshold is determined to be 15 degrees based on the temperature change. Thus, at 9:30, the indoor temperature is adjusted to 15 degrees, and by the time the fluid exchange begins at 10:00, the room temperature has just reached the minimum temperature standard of 25 degrees. If the indoor temperature change is: a 10-degree decrease between 9:30 and 10:00, the third temperature threshold is determined to be 38 degrees based on the temperature change. At 9:30, the indoor temperature is adjusted to 38 degrees, and by the time the fluid exchange begins at 10:00, the room temperature has just reached the maximum temperature standard of 28 degrees.

[0059] Optionally, humidity adjustment is performed based on the humidity comparison result, including: when the current ambient humidity is less than the first humidity threshold, triggering the humidifier to turn on, and raising the current ambient humidity to a third humidity threshold within the ambient adjustment time; when the current ambient humidity is greater than the second humidity threshold, triggering the dehumidifier to turn on, and lowering the current ambient humidity to a fourth humidity threshold within the ambient adjustment time; the fourth humidity threshold < first humidity threshold < second humidity threshold < third humidity threshold.

[0060] Alternatively, the first humidity threshold is 50% and the second humidity threshold is 60%. In some embodiments, when the current humidity is far above 60%, indicating a humid climate and a rapid increase in indoor humidity, the indoor humidity parameter is adjusted to a fourth humidity threshold, which is far below the standard humidity range of 50%-60%. In this way, from the end of the environmental conditioning time to the start of peritoneal dialysis fluid exchange, the indoor humidity begins to increase from the fourth humidity threshold. By the time peritoneal dialysis fluid exchange begins, the peritoneal dialysis fluid exchange room can still provide a more comfortable humidity for the patient. Conversely, when the humidity is too low, the current humidity is far below 50%, indicating a dry climate and a decrease in indoor humidity, the indoor humidity parameter is adjusted to a third humidity threshold, which is far greater than the second humidity threshold. In this way, by the time peritoneal dialysis fluid exchange begins, the humidity in the peritoneal dialysis fluid exchange room can meet the patient's fluid exchange conditions.

[0061] Optionally, performing humidity adjustment according to the humidity comparison result further includes: obtaining a humidity change rate of the peritoneal dialysis fluid exchange chamber according to the current ambient humidity, and determining a first humidity threshold or a fourth humidity threshold according to the humidity change of the peritoneal dialysis fluid exchange chamber.

[0062] Optionally, the current ambient humidity and current climate data are obtained, and the historical climate of the same geographical location as the current climate is searched in the network database to obtain the indoor humidity changes of the same historical climate in the same period, and the humidity change rate of the peritoneal dialysis exchange room is determined based on the found indoor humidity changes.

[0063] In some embodiments, based on the current ambient humidity and current climate data, if the indoor humidity change for the same geographic location and historical climate is: a 5% increase between 9:30 and 10:00, then the fourth humidity threshold is determined to be 45% based on the humidity change. Thus, at 9:30, the indoor humidity is adjusted to 45%, and by 10:00, when the fluid exchange begins, the indoor humidity has just reached the minimum humidity standard of 50%. If the indoor humidity change is: a 5% decrease between 9:30 and 10:00, then the third humidity threshold is determined to be 65%, based on the humidity change. At 9:30, the indoor humidity is adjusted to 65%, and by 10:00, when the fluid exchange begins, the indoor humidity has just reached the maximum humidity standard of 60%.

[0064] Optionally, step-by-step early warning protection is performed based on the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration, including: when one or more of the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration is within the first-level warning range, the environmental data within the first-level warning range will be marked in red and displayed on the preset display screen; when multiple of the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration are within the second-level warning range, the alarm will be triggered to sound three alarms, and the environmental data within the second-level warning range will be marked in red on the preset display screen; when the real-time dust concentration and real-time oxygen concentration are within the third-level warning range, the alarm will be triggered to sound a continuous alarm, and the real-time dust concentration and real-time oxygen concentration will be marked in red on the preset display screen.

[0065] Optionally, one or more of the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration being in the first level warning range includes: the absolute value of the difference between the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration and their respective corresponding standard ranges being in the first level warning range.

[0066] In some embodiments, when the real-time temperature is 20 degrees, which is 5 degrees different from the minimum temperature standard and is in the first-level warning range, the real-time temperature data will be displayed in red on the display screen to remind the patient that the current temperature is low and to take protective measures as soon as possible.

[0067] Optionally, multiple of the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration are in the second-level warning range, including: the difference between two or more of the real-time temperature, real-time humidity, real-time dust concentration and real-time oxygen concentration and their respective corresponding standard ranges is in the second-level warning range.

[0068] In some embodiments, when the real-time humidity is 40%, which is 10% different from the minimum humidity standard and is in the second-level warning range, the real-time humidity data will be displayed in red on the display screen and an alarm will be sounded to remind the patient that the current humidity is low and it is very easy to breed bacteria, and the fluid change operation must be completed as soon as possible or protective measures must be taken.

[0069] In some embodiments, oxygen is a necessary condition for human survival, and in order to ensure sterile or low-bacteria conditions, the peritoneal dialysis exchange room needs to close doors and windows. For some relatively narrow peritoneal dialysis exchange rooms, if patients stay in them for a long time, the oxygen concentration may be too low, affecting the patient's breathing and having a negative impact on the body. In a few peritoneal dialysis exchange rooms with too high oxygen concentrations, bacteria are more likely to breed, and too high dust concentrations are also more likely to cause infection in patients. Therefore, when the oxygen concentration and dust concentration are in the third-level warning range, the alarm is triggered to emit a continuous alarm sound, urging the patient to leave the peritoneal dialysis exchange room immediately, ensuring the patient's safety and reducing the probability of infection during the exchange.

[0070] Combine Figure 2 and Figure 4 As shown, the present invention provides an environmental monitoring device for peritoneal dialysis fluid exchange, based on the above-mentioned environmental monitoring method for peritoneal dialysis fluid exchange, comprising a square shell 1 and an inner cavity 2; a plurality of display screens 3 are provided on one side of the square shell, and a support plate 7 is provided on the other side of the square shell; a controller, an alarm, a temperature and humidity sensor, a dust sensor, and an oxygen concentration sensor are provided in the inner cavity; the controller is respectively connected to the alarm, the temperature and humidity sensor, the dust sensor, the oxygen concentration sensor and each display screen.

[0071] Optionally, the temperature and humidity sensor includes a temperature sensor and a humidity sensor.

[0072] Optionally, the controller is used to receive environmental parameters collected by temperature and humidity sensors, dust sensors and oxygen concentration sensors, send each environmental parameter to each display screen for display, and adjust the peritoneal dialysis fluid exchange chamber according to the current environmental parameters during the environmental adjustment time. It is also used to perform step-by-step early warning and protection according to real-time environmental parameters during the peritoneal dialysis fluid exchange time.

[0073] Optionally, the current environmental parameters include current environmental temperature, current environmental humidity, and current environmental dust concentration. The real-time environmental parameters include real-time temperature, real-time humidity, real-time dust concentration, and real-time oxygen concentration.

[0074] In some embodiments, the controller compares the current ambient temperature with the first temperature threshold and the second temperature threshold respectively to obtain a temperature comparison result, and adjusts the temperature according to the temperature comparison result; compares the current ambient humidity with the first humidity threshold and the second humidity threshold respectively to obtain a humidity comparison result, and adjusts the humidity according to the humidity comparison result; compares the current ambient dust concentration with the preset dust concentration threshold, and triggers the air purifier to turn on when the current ambient dust concentration is greater than the preset dust concentration threshold.

[0075] Combine Figure 2 As shown, optionally, an environmental monitoring device for peritoneal dialysis fluid exchange includes a host computer and a camera 4. The host computer is communicatively connected to the controller, and is used to receive current environmental parameters sent by the controller and adjust the peritoneal dialysis fluid exchange chamber according to the current environmental parameters; the camera 4 is set at the top of the square shell 1, and the controller controls the camera to take pictures of the peritoneal dialysis fluid exchange chamber during the peritoneal dialysis fluid exchange time.

[0076] Combine Figure 3 As shown, in some embodiments, the controller 10 is in communication with the host computer 11. After the host computer 11 obtains the peritoneal dialysis fluid exchange time, it obtains the environmental adjustment time based on the peritoneal dialysis fluid exchange time and sends it to the controller 10. After the environmental adjustment begins, the controller 10 obtains the current environmental parameters and sends the current environmental parameters to the host computer 11. The host computer triggers the air conditioner, humidifier, dehumidifier, and air purifier and other equipment to adjust the parameters based on the current environmental parameters. The controller 10 is respectively connected to the temperature and humidity sensor 12, dust sensor 13, and oxygen concentration sensor. After the peritoneal dialysis fluid exchange begins, the temperature and humidity sensor 12, dust sensor 13, and oxygen concentration sensor 14 are triggered to start real-time data collection. The temperature and humidity sensor 12, dust sensor 13, and oxygen concentration sensor 14 send the collected data to the controller 10, and the controller 10 sends the collected data to the display screen 3 and the host computer 11. At the same time, the controller 10 is also connected to the alarm 5, which is triggered according to the collected real-time temperature, real-time humidity, real-time dust concentration, and real-time oxygen concentration to provide step-by-step early warning protection.

[0077] Combine Figure 4 As shown, optionally, the connection end of the support plate 7 is disposed on the edge of the square housing 1, and a hole is provided at the free end of the support plate 1. A hook 9 on the wall is inserted into the hole of the support plate 7, and the environmental monitoring device is fixed to the wall, forming a V-shape with the wall surface 8. This allows the patient to see the data on the display screen even when standing directly below or close to the environmental monitoring device, thereby increasing the patient's viewing angle and providing greater convenience.

[0078] In some embodiments, the environmental monitoring device for peritoneal dialysis fluid exchange simultaneously monitors the temperature, humidity, dust concentration, and oxygen concentration in the peritoneal dialysis fluid exchange chamber in real time. The host computer and the environmental monitoring device for peritoneal dialysis fluid exchange adjust the ambient temperature of the peritoneal dialysis fluid exchange chamber before peritoneal dialysis fluid exchange, thereby providing a more comfortable fluid exchange environment for the patient and reducing the probability of infection during the fluid exchange operation. Furthermore, the environmental monitoring device for peritoneal dialysis fluid exchange can be hung on the wall, allowing the patient or doctor to view the current environmental parameters at any time, greatly facilitating peritoneal dialysis fluid exchange operations.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
