Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a method and system for detecting the concentration of saline sol in a diffusion mode of a saline sol therapeutic device based on a saline solution. Background Art

[0002] Salt sol therapy device, also known as rock salt aerosol therapy device, is a salt therapy device that produces salt sol (salt sol is an aerosol formed by dry salt particles dispersed and suspended in the air) to treat patients with respiratory diseases. There are currently two types of rock salt aerosol generating equipment on the market. One is to directly grind the salt mine and blow it out to form salt aerosol; the other is to produce rock salt aerosol based on salt solution, specifically to atomize the salt solution into salt mist, and then dry it to form salt aerosol; among them, salt solution generates salt aerosol because the salt aerosol particles formed by it have small particle size and uniform particle size, so they can enter the human lungs for treatment, achieving better therapeutic effects, becoming the first choice in the salt therapy industry.

[0003] There are two ways for patients to receive treatment with a salt sol therapy device. One is to use a small salt sol therapy device and perform single-person treatment through a breathing mask, which is the single-person mode. The other is to build a salt therapy room and use the salt sol therapy device to generate salt sol and diffuse it into the entire salt therapy room for use by multiple people, which is the diffusion mode.

[0004] Accurate detection of saline sol concentration is an important condition for achieving precision treatment. Currently, saline sol concentration is mainly detected through PM2.5 concentration sensors. However, in diffusion mode, due to the presence of other particulate matter in the air of the treatment environment, the data detected by the PM2.5 concentration sensor is inaccurate and cannot truly reflect the concentration of saline sol. As a result, the saline sol concentration cannot be accurately controlled, affecting the effect of precision treatment. Summary of the Invention

[0005] In order to solve the problem of inaccurate salt sol concentration detection in the diffusion mode of the above-mentioned salt solution-based salt sol therapy device, the present invention provides a salt sol concentration detection method in the diffusion mode of the salt solution-based salt sol therapy device. According to the fact that the ratio of salt mass to water mass of the salt solution remains unchanged before and after atomization, the concentration of the salt sol is calculated by detecting the change in relative humidity in the treatment environment.

[0006] To achieve the above object, the present invention proposes a technical solution, a method for detecting the concentration of saline sol in the diffusion mode of a saline sol therapeutic device based on a saline solution, comprising the following steps:

[0007] S1 obtains the parameters of relative humidity, temperature and saline solution concentration of the treatment environment;

[0008] S2 obtains the absolute humidity increase based on the relative humidity of the treatment environment and the ring temperature;

[0009] S3 calculates the concentration of the salt sol in the treatment environment according to the absolute humidity increase and the concentration of the salt solution.

[0010] Furthermore, in step S1, the relative humidity of the treatment environment includes the initial relative humidity of the treatment environment and the current relative humidity of the treatment environment, and the initial relative humidity of the treatment environment and the current relative humidity of the treatment environment are obtained through a hygrometer; the temperature of the treatment environment includes the initial treatment environment temperature and the current treatment environment temperature, and the initial treatment environment temperature and the current treatment environment temperature are obtained through a thermometer.

[0011] Specifically, the treatment environment is a relatively closed space such as a salt therapy room, a family bedroom, or a salt therapy chamber.

[0012] The salt solution concentration parameters can be obtained directly from the salt solution configuration ratio or measured by a salinity meter.

[0013] Furthermore, in step S2, relative humidity is defined as the percentage of the water vapor pressure in the air to the saturated water vapor pressure at the same temperature, or the ratio of the absolute humidity of moist air to the saturated absolute humidity that can be achieved at the same temperature, which can also be expressed as the ratio of the water vapor partial pressure in moist air to the saturated pressure of water at the same temperature;

[0014] According to the definition of relative humidity, one expression of relative humidity is:

[0015]

[0016] Where: RH is relative humidity; ρ is absolute humidity, unit is g / m 3 ρ t The saturated absolute humidity at the treatment environment temperature T, in g / m 3 .

[0017] Furthermore, the absolute humidity increase can be expressed as:

[0018] ρ increase = ρ2 - ρ1 (2)

[0019] Where: 增 is the absolute humidity increase, unit is g / m 3 ; ρ2 is the current environmental absolute humidity, unit is g / m 3 , ρ1 is the initial environmental absolute humidity, unit is g / m 3 .

[0020] Specifically, according to the definition of absolute humidity, absolute humidity is the mass of water vapor per unit volume of air, in g / m 3 In other words, absolute humidity is the concentration of water vapor in the air, that is, the increase in absolute humidity reflects the increase in the mass of water vapor in unit volume of air, that is, the increase in water vapor concentration.

[0021] Furthermore, in step S3, the salt solution expression is:

[0022]

[0023] Where: C 溶 is the concentration of salt solution, M 盐 is the mass of salt in the salt solution, in g; M 水 is the mass of water in the salt solution, in g;

[0024] The ratio of the increased water vapor concentration in the air to the salt sol concentration is equal to the ratio of the water mass to the salt mass in the salt solution, and the expression is:

[0025]

[0026] Where: C 盐 is the concentration of saline sol in the treatment environment, in mg / m 3 ρ 增 The water vapor concentration in the treatment environment (i.e., the absolute humidity increase) is expressed in g / m 3 ;M 盐 is the mass of salt in the salt solution, in g; M 水 is the mass of water in the salt solution, in g.

[0027] In a treatment setting, the added water vapor in the air can be considered the water vapor generated by the atomization of the saline solution. During atomization, salt and water enter the air in proportion to the concentration of the saline solution. That is, the mass of salt and water entering the air is proportional to the mass of salt and water in the saline solution. Therefore, the concentration of salt entering the air and the concentration of water entering the air are proportional to the mass of salt and water in the saline solution. Before the formation of the halosol, some water was already present in the air, so the concentration of water vapor entering the air through atomization is equal to the increase in the water vapor concentration in the air.

[0028] Furthermore, the salt sol concentration formula is:

[0029]

[0030] Where: C 盐 is the concentration of saline sol in the treatment environment, in mg / m 3 ; C 溶 is the concentration of saline solution; RH2 is the relative humidity of the current treatment environment; RH1 is the relative humidity of the initial treatment environment; ρ T2 The saturated absolute humidity corresponding to the current treatment environment temperature T2, in g / m 3 ρ T1 is the saturated absolute humidity corresponding to the initial treatment environment temperature T1, in g / m 3 .

[0031] Saturated absolute humidity ρ t : The maximum content of water vapor in the air at a certain temperature T. The higher the temperature T, the more water vapor can be contained in a unit volume of air, and the saturated absolute humidity ρ T The larger the saturated absolute humidity ρ T Positively correlated with temperature T.

[0032] According to formula (5), the concentration of the saline solution is obtained when the solution is prepared. It is only necessary to detect the ambient temperature and relative humidity before the start of the saline sol therapy device, as well as the current ambient temperature and humidity, to obtain the concentration of the saline sol in the treatment environment, regardless of whether there are other particulates in the treatment environment.

[0033] Specifically, the relative humidity of the treatment environment ranges from 40% to 60%.

[0034] Specifically, the treatment environment temperature range is 18°C ​​to 26°C.

[0035] In order to realize the detection of salt sol concentration in the diffusion mode, a detection system of salt sol concentration in the diffusion mode is also disclosed, including a hygrometer and a processor;

[0036] The hygrometer is used to detect the temperature and relative humidity of the environment and transmit the detected data to the processor;

[0037] The processor receives data detected by the thermometer and the hygrometer, calculates the concentration of the salt sol, and displays the concentration of the salt sol on the display.

[0038] A hygrometer can detect both the temperature and relative humidity of the environment at the same time, or both a thermometer and a hygrometer can be used for measurement at the same time.

[0039] Furthermore, the processor can display the salt sol concentration in real time; an interval time t can also be set to collect temperature and relative humidity data once every time t, and display the salt sol concentration once.

[0040] Beneficial effects of the present invention:

[0041] 1. The salt sol concentration is calculated by measuring the relative humidity of the environment based on the relationship between the absolute humidity increase, salt sol concentration and salt solution concentration in the salt therapy room. This method is less affected by the environment and is not affected by impurity particles in the environment, and can accurately detect the concentration of salt sol.

[0042] 2. This measurement method is simple in logic and does not require the use of expensive detection instruments. It can accurately detect the concentration of salt sol in the salt therapy room using only a conventional hygrometer. It is low in cost and has strong applicability.

The drawings are used to provide a further understanding of the present invention and constitute a part of the specification.

For those skilled in the art, other drawings can be obtained based on the drawings without paying any creative work.

[0045] Figure 2 Schematic diagram of the salt sol concentration detection system under the diffusion mode of the present invention. DETAILED DESCRIPTION

[0046] The following is a combination of the embodiments of the present invention Figure 1 and Figure 2 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

[0047] like Figure 1 As shown, a method for detecting the concentration of saline sol in the diffusion mode of a saline sol therapeutic device based on saline solution includes the following steps:

[0048] S1 obtains the parameters of ambient relative humidity, ambient temperature and salt solution concentration;

[0049] S2 obtains the absolute humidity increase based on the ambient relative humidity and ambient temperature;

[0050] S3 calculates the concentration of salt sol in the environment based on the increase in absolute humidity and the concentration of the salt solution.

[0051] In step S1, the ambient relative humidity includes the initial treatment environment relative humidity and the current treatment environment relative humidity, and the initial treatment environment relative humidity and the current treatment environment relative humidity are obtained through a hygrometer; the ambient temperature includes the initial treatment environment temperature and the current treatment environment temperature, and the initial treatment environment temperature and the current treatment environment temperature are obtained through a thermometer.

[0052] In this embodiment, the treatment environment is a salt therapy room (i.e., a salt sol treatment room).

[0053] The salt solution concentration parameters can be obtained directly from the salt solution configuration ratio or measured by a salinity meter.

[0054] In step S2, the expression (1) of relative humidity is obtained according to the definition of relative humidity:

[0055]

[0056] Where: RH is relative humidity; ρ is absolute humidity, unit is g / m 3 ρ T The saturated absolute humidity at ambient temperature T, in g / m 3 .

[0057] The specific meaning is:

[0058] Absolute humidity ρ: the mass of water vapor per unit volume of air, unit: g / m 3 ;

[0059] Saturated absolute humidity ρ T : The maximum content of water vapor in the air at a certain temperature T, in g / m 3 ;

[0060] Relative humidity RH: the percentage of water vapor pressure in the air to the saturated water vapor pressure at the same temperature, or the ratio of the absolute humidity of moist air to the saturated absolute humidity that can be reached at the same temperature. It can also be expressed as the ratio of the water vapor partial pressure in moist air to the saturated pressure of water at the same temperature.

[0061] From the above formula we can see that the saturated absolute humidity ρ T It is not fixed, but changes with temperature. The higher the temperature T, the more water vapor can be contained in a unit volume of air, and the saturated absolute humidity ρ T The larger the saturated absolute humidity ρ T Positively correlated with temperature T.

[0062] It should be noted that the saturated absolute humidity ρ at different temperatures T t It can be obtained through experimental measurement, aerodynamic calculation, or by querying the temperature-saturated absolute humidity (i.e., saturated water vapor table) comparison table. In this embodiment, the saturated absolute humidity ρ at different temperatures T is obtained by querying the temperature-saturated absolute humidity comparison table. T .

[0063] Furthermore, the absolute humidity increase can be expressed as formula (2):

[0064] ρ increase = ρ2 - ρ1 (2)

[0065] Where: 增 is the absolute humidity increase, ρ2 is the current environmental absolute humidity, and ρ1 is the initial environmental absolute humidity.

[0066] It should be noted that at different temperatures T, the saturated absolute humidity ρT Therefore, the change in relative humidity cannot directly reflect the increase in water vapor in the air. The change in absolute humidity is needed to reflect the actual increase in water vapor per unit volume.

[0067] Specifically, according to the definition of humidity, absolute humidity is the concentration of water vapor in the air, that is, the increase in absolute humidity is the increase in water vapor concentration in the air.

[0068] In step S3, the salt solution expression (3) is obtained according to the salt solution concentration definition:

[0069]

[0070] Where: C 溶 is the concentration of salt solution, in g / m 3 , M 盐 is the mass of salt in the salt solution, in g; M 水 is the mass of water in the salt solution, in g;

[0071] The ratio of the water vapor concentration evaporated into the air by the salt sol therapy device to the salt sol concentration is the same as the ratio of the water mass to the salt mass in the salt solution, that is, the ratio of the increased water vapor concentration in the air to the salt sol concentration is equal to the ratio of the water mass to the salt mass in the salt solution. Expression (4) is:

[0072]

[0073] Where: C 盐 is the salt sol concentration, unit is mg / m 3 ρ 增 is the increased water vapor concentration (i.e., the increase in absolute humidity), in g / m 3 , M 盐 is the mass of salt in the salt solution, in g, M 水 is the mass of water in the salt solution, in g.

[0074] In a treatment setting, the added water vapor in the air can be considered the water vapor generated by the atomization of the saline solution. During atomization, salt and water enter the air in proportion to the concentration of the saline solution. That is, the mass of salt and water entering the air is proportional to the mass of salt and water in the saline solution. Therefore, the concentration of salt entering the air and the concentration of water entering the air are proportional to the mass of salt and water in the saline solution. Before the formation of the halosol, some water was already present in the air, so the concentration of water vapor entering the air through atomization is equal to the increase in the water vapor concentration in the air.

[0075] It should be noted that the salt sol in this embodiment refers to an ideal state of complete drying; in actual use, the water in the salt sol is not completely dry, but the water content is generally within 0.3%, which can be ignored and is calculated based on the ideal drying state.

[0076] In this embodiment, formula (1), (2), and (3) are substituted into formula (4) to obtain formula (5) for the concentration of the salt sol:

[0077]

[0078] Where: C 盐 is the salt sol concentration, unit is mg / m 3 ; C 溶 is the concentration of saline solution, RH2 is the relative humidity of the current treatment environment, and RH1 is the relative humidity of the initial treatment environment; ρ T2 The saturated absolute humidity corresponding to the current treatment environment temperature T2, in g / m 3 ρ T1 is the saturated absolute humidity corresponding to the initial treatment environment temperature T1, in g / m 3 .

[0079] The concentration of the salt solution can be calculated when the solution is prepared, or displayed when the salt solution is purchased, or detected by a salt concentration meter.

[0080] According to formula (5), the concentration of the saline solution in this embodiment is obtained when the solution is prepared. It is only necessary to detect the ambient temperature and relative humidity before the start of the saline sol therapy device, as well as the current ambient temperature and humidity, to obtain the concentration of the saline sol in the treatment environment, regardless of whether there are other particulate matter in the treatment environment.

[0081] In this embodiment, the relative humidity RH of the treatment environment ranges from 40% to 60%.

[0082] In this embodiment, the treatment environment temperature T ranges from 18 to 26°C.

[0083] It should be noted that in this embodiment, the relative humidity range and the temperature range of the treatment environment are only set to achieve the best treatment effect and provide the most comfortable treatment environment for patients, but are not limited to the relative humidity and temperature shown in this embodiment and are still applicable under other relative humidity and temperature conditions.

[0084] It is known that the relationship between saturated absolute humidity and temperature is (6):

[0085]

[0086] Where: S is the saturated absolute humidity, unit is g / m 3; e is a constant representing the base of the natural logarithm function, and its value is approximately 2.71828; T is the thermodynamic temperature, in K; P is the absolute pressure, in Pa;

[0087] The conversion formula between Celsius and Kelvin temperature in thermodynamic temperature is:

[0088] T(K)=T(℃)+273.15

[0089] T(K) is the thermodynamic temperature (Kelvin), and T(°C) is the Celsius temperature.

[0090] In particular, in the present invention, only in formula (6) and its description, T represents thermodynamic temperature, with the unit being K; in any other place, T represents Celsius temperature.

[0091] In the present invention, the saturated absolute humidity S at temperature T is expressed as ρ T .

[0092] An example of a treatment environment is a salt therapy room with a space of 50m 3 , close doors and windows, air purifier or fresh air system to form a relatively closed space. Before turning on the salt sol therapy device, the ambient temperature T1 of the salt therapy room is measured to be 20℃ through a thermometer, and the relative humidity RH1 of the salt therapy room is measured to be 50% through a hygrometer. The concentration of the salt solution used by the salt sol therapy device is 10%; set the salt sol output concentration, and after turning on the salt sol therapy device for 30 minutes, the current temperature T2 of the salt therapy room is measured to be 20℃, and the relative humidity RH2 is 51%. The ambient temperature has not changed, ρ T2 =ρ T1 By looking up the temperature-saturated absolute humidity comparison table in Table 1, we can get the saturated absolute humidity ρ corresponding to the ambient temperature of 20℃. T1 17.3g / m 3 , put it into formula (5) to get:

[0093]

[0094] The current salt sol concentration is: C 盐 =19.22mg / m 3 .

[0095] Table 1 Temperature-saturated absolute humidity comparison table

[0096]

[0097] It should be noted that the temperature-saturated absolute humidity comparison table in Table 1 is usually called a saturated water vapor table or a saturated absolute humidity table.

[0098] In a further embodiment, after the treatment is completed, the salt sol therapy device is turned off, the salt therapy room is disinfected and fully ventilated to purify the indoor air to ensure the accuracy of concentration detection when the salt sol therapy device is turned on again.

[0099] like Figure 2 As shown, in order to detect the concentration of salt sol in the diffusion mode, the detection system used in this embodiment includes a thermometer, a hygrometer, and a processor;

[0100] The thermometer is used to detect the temperature of the environment and transmit the detected data to the processor;

[0102] The processor receives data detected by the thermometer and the hygrometer, calculates the concentration of the salt sol, and displays the concentration of the salt sol on the display in real time.

[0103] Specifically, the processor obtains data detected by the thermometer and the hygrometer in a wired or wireless manner.

[0104] In this embodiment, the thermometer and the hygrometer are directly connected to the processor and can provide real-time feedback of the detected temperature and humidity data.

[0105] It should be noted that the processor can display the salt sol concentration in real time; the processor can also set an interval time t, collect data once every time t, and display the salt sol concentration once.

[0106] The above interval time t can be set according to actual treatment conditions, equipment status, standard requirements and other conditions, and can be 30s, 1min, 2min, etc., or any other time interval that meets the requirements.

[0107] Specifically, the processor stores the salt sol concentration calculation formula (5), and enters the temperature-saturated absolute humidity comparison table and the temperature-saturated absolute humidity corresponding relationship formula. After obtaining the temperature parameters and relative humidity parameters from the hygrometer, the corresponding saturated absolute humidity can be automatically extracted to calculate the current salt sol concentration.

[0108] In this embodiment, the hygrometer can feed back the ambient temperature and relative humidity to the processor in real time, and the processor can display the current salt sol concentration in real time based on the received temperature data and relative humidity data.

[0109] In a further embodiment, the processor can also be connected to a signal terminal through a network, including but not limited to fixed terminals or mobile terminals such as computers, mobile phones, and mobile computers; the network connection includes communication lines, wifi signal wireless connections, cloud platforms and other data transmission methods; the salt sol concentration of the treatment environment can be displayed in real time on the signal terminal, which is convenient for medical staff and patients to view.

[0116] e. After the treatment, turn off the salt sol therapy device and the patient leaves the salt therapy room;

[0117] f. Disinfect the salt therapy room, ventilate it and purify the indoor air.

[0118] In a further embodiment, before the salt sol therapy device is turned on, the temperature of the salt therapy room is adjusted to 18° C. to 26° C. and the relative humidity is adjusted to 40% to 60% to increase the comfort of the patient's treatment.

[0119] In a further embodiment, if the patient has an abnormal reaction during treatment, an alarm message is promptly issued and the patient is transferred for emergency treatment.

[0120] In a further embodiment, after the treatment is completed, the patient rinses his mouth with water after leaving the salt therapy room to prevent the salt sol from over-stimulating the patient's oral mucosa.
