Abstract
Description
Technical Field
[0001] This invention relates to the field of fumigation therapy technology, specifically to a dermatological drug atomization fumigation device. Background Technology
[0002] In clinical dermatology, drug fumigation therapy is a commonly used external treatment method in traditional Chinese medicine. It mainly uses the chemical and physical effects of hot medicinal steam to allow the medicinal components to be absorbed through the skin, thereby achieving the therapeutic effects of unblocking meridians, regulating qi and blood, and eliminating pathogens and strengthening the body's resistance. It can be widely used in the treatment of skin diseases such as eczema, neurodermatitis, and chronic pruritus.
[0003] In traditional fumigation equipment, liquid Chinese medicine is typically converted into tiny mist particles, which are then sprayed directly onto the skin along with steam. This allows the medicine to penetrate the skin's surface and stratum corneum more easily, reaching the dermis and subcutaneous tissue, significantly improving drug absorption efficiency. However, since steam is sprayed directly onto the skin surface, excessively high steam temperatures can easily burn the skin. Conversely, if the fumigation temperature is too low, skin pores cannot open fully, reducing drug penetration. Furthermore, during steam delivery through pipes, the steam accumulates on the skin surface, and the originally fine steam particles condense and aggregate into larger particles, affecting drug absorption. Therefore, this invention provides a dermatological drug atomization fumigation device to reduce the accumulation of atomized drugs at the skin contact point, ensure the temperature stability and particle dispersion of the atomized drugs, and improve drug absorption. Summary of the Invention
[0004] To address the aforementioned issues, this invention provides a dermatological drug atomization fumigation device, which reduces the aggregation of atomized drugs at the skin contact site, ensures the temperature stability and particle dispersibility of the atomized drugs, and improves drug absorption.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a dermatological drug atomization fumigation device, comprising a fumigation machine body for generating atomized drug liquid, the fumigation machine body being connected to a ventilation pipe for conveying the atomized drug liquid; the ventilation pipe being connected to a fumigation head for contacting the patient's skin, a detection chamber being provided at the connection between the fumigation head and the ventilation pipe, and a first temperature sensor being provided in the detection chamber for detecting real-time temperature data of the atomized drug liquid.
[0006] The fumigation head is equipped with a vibration mechanism for dispersing the atomized drug solution. The vibration mechanism includes a heating bladder located in the detection chamber. A power component for squeezing the heating bladder is provided on one side of the heating bladder. The heating bladder is connected to an exchange tube. A heat exchange plate is rotated and fitted on the fumigation head. The heat exchange plate is arranged alternately around the fumigation head. A push bladder connected to the exchange tube is provided between the heat exchange plate and the fumigation head.
[0007] It also includes a control panel, which is used to adjust the rotation speed of the power components based on real-time temperature data, and the heat exchange fins adjust the expansion of the propulsion bladder according to the gas output of the heating bladder.
[0008] Furthermore, the power component includes a motor, which is fixedly connected to the outer wall of the testing chamber. The output shaft of the motor is rotatably engaged with the testing chamber. A cam is eccentrically fixedly connected to the output shaft of the motor, and the cam is located on the side of the heating bag away from the fumigation head.
[0009] A bracket is fixedly connected to the side of the heating bag near the fumigation head, and the side of the heating bag away from the ventilation pipe is fixedly connected to the detection chamber through the bracket; the heating bag is connected to the outside world and the pushing bag through the exchange pipe respectively, and a second one-way valve is provided for the exchange pipe between the heating bag and the outside world, and a first one-way valve is provided for the exchange pipe between the heating bag and the pushing bag.
[0010] When the heating element is in its normal state, there is a gap between the cam and the heating element; when the heating element is in a compressed state, the cam abuts against the heating element.
[0011] Furthermore, a vibrating plate is also fitted inside the testing chamber and the fumigation head with a gap, with one end of the vibrating plate located between the cam and the testing chamber;
[0012] An installation block is fixedly connected to the inner wall of the fumigation head. A movable block is slidably fitted on the installation block. The end of the movable block away from the installation block is rotatably fitted with the heat exchange plate. The push bag is located between the bottom of the heat exchange plate and the installation block. The movable block is fixedly connected to the end of the vibrating plate away from the cam.
[0013] Furthermore, springs are fixedly connected to both sides of the movable block, and the end of the spring away from the movable block is fixedly connected to the mounting block.
[0014] Furthermore, the length of the heat exchange fins gradually increases along the gas delivery direction of the ventilation duct, and an extension fin is fixedly connected to the side of the heat exchange fins closest to the ventilation duct.
[0015] Furthermore, the fumigation head has several heat dissipation holes, and a filter screen is installed between the heat dissipation holes and the heat exchange tube; the end of the heat exchange tube away from the heating bag is connected to the outside through the filter screen.
[0016] Furthermore, the push bag is connected to a discharge pipe, which is located inside the moving block; and the moving block has a mating cavity, in which a squeezing block is rotatably mated, the squeezing block is fixedly connected to the heat exchange plate, and one end of the discharge pipe is located inside the mating cavity;
[0017] When the push bladder is in a contracted state, the squeeze block separates from the discharge tube; when the push bladder is fully inflated, the squeeze block abuts against the discharge tube.
[0018] Furthermore, the control panel is also electrically connected to a second temperature sensor and an electric heating tube. The second temperature sensor is located on the heat exchange plate, and the heat exchange plate on which the second temperature sensor is installed is located on the side of the heat exchange plate away from the detection chamber; the electric heating tube is located on the side of the filter screen close to the heat exchange tube, and the electric heating tube is arranged in a ring around the fumigation head.
[0019] The second temperature sensor is used to measure the comparative temperature data around the heat exchanger in real time. The control panel is also used to compare the real-time temperature data with the set standard range. If the real-time temperature is greater than the standard range, the step temperature between the real-time temperature and the maximum value of the standard range is calculated, and the corresponding speed adjustment command is obtained to the power unit based on the step temperature. If the real-time temperature is within the standard range, a standby command is sent to the power unit. If the real-time temperature is less than the standard range, a start command is sent to the electric heating tube until the real-time temperature is consistent with the standard range.
[0020] Meanwhile, the control panel compares the comparison temperature data with the burn temperature. If the comparison temperature data is greater than the burn temperature, the control panel displays an alarm command; if the comparison temperature data is less than the burn temperature, it determines whether the comparison temperature data is within the standard range. If the comparison temperature data is within the standard range, it sends a standby command to the electric heating element; if the comparison temperature data is not within the standard range, it sends a start command to the electric heating element.
[0021] Furthermore, the control panel is also used to calculate the difference between real-time temperature data and comparative temperature data, compare the difference with the set change value, and if the difference is greater than the change value, an abnormal operation command is displayed; if the difference is less than or equal to the change value, a normal operation command is displayed.
[0022] Furthermore, a suction cup is fixedly connected to the end of the fumigation head away from the testing chamber, and the suction cup is arranged circumferentially around the outer edge of the fumigation head.
[0023] The above approach has the following beneficial effects:
[0024] 1. In this solution, during the continuous heating of the medicinal liquid by the fumigation machine body to form an atomized medicinal liquid, the atomized medicinal liquid is transported to the fumigation head through the ventilation pipe. The real-time temperature of the atomized medicinal liquid is measured by the first temperature sensor. The control panel adjusts the rotation speed of the power component based on the real-time temperature. The faster the rotation speed of the power component, the greater the amount of gas expelled by the heating bladder through the exchange pipe, resulting in a greater expansion of the bladder. This increases the degree of blockage of the heat exchange plate inside the fumigation head, prolongs the cooling time of the atomized medicinal liquid, and reduces the risk of burns when the atomized medicinal liquid comes into contact with the skin.
[0025] 2. In this solution, during the process of the power component driving the heating bag to move, the reciprocating expansion of the driving bag is used to re-disperse the atomized drug liquid in contact with the heat exchange plate, thereby reducing the aggregation of the atomized drug liquid due to continuous condensation, thus ensuring the particle dispersion of the atomized drug liquid and improving the drug absorption effect.
[0026] 3. This solution uses a control panel to cool and disperse the atomized medicine in the ventilation duct, which reduces the accumulation of atomized medicine at the skin contact point, thus facilitating the absorption of the medicine by the skin at the fumigation site.
[0027] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0037] The following detailed description illustrates the specific implementation method:
[0038] Example 1:
[0039] As attached Figures 1 to 5 As shown: A dermatological drug atomizing fumigation device includes a fumigation machine body (not shown) for generating atomized drug solution, the fumigation machine body is connected to a ventilation pipe 1 for conveying the atomized drug solution; the ventilation pipe 1 is connected to a fumigation head 2 for contacting the patient's skin, and a detection chamber 3 is provided at the connection between the fumigation head 2 and the ventilation pipe 1, and a first temperature sensor (not shown) is provided in the detection chamber 3 for detecting the real-time temperature data of the atomized drug solution.
[0040] The fumigation head 2 is equipped with a vibration mechanism for dispersing the atomized drug solution. The vibration mechanism includes a heating bladder 32 located in the detection chamber 3. A power component (not shown in the figure) for squeezing the heating bladder 32 is provided on one side of the heating bladder 32. The heating bladder 32 is connected to an exchange tube 7. A heat exchange plate 4 is rotatably fitted on the fumigation head 2. The heat exchange plate 4 and the fumigation head 2 are arranged alternately with the heat exchange plate 4 as the center. A push bladder 42 connected to the exchange tube 7 is provided between the heat exchange plate 4 and the fumigation head 2.
[0041] The power component includes a motor (not shown in the figure), which is fixedly connected to the outer wall of the detection chamber 3. The output shaft of the motor is rotatably engaged with the detection chamber 3. A cam 31 is eccentrically fixedly connected to the output shaft of the motor. The cam 31 is located on the side of the heating bag 32 away from the fumigation head 2. A bracket is fixedly connected to the side of the heating bag 32 near the fumigation head 2. The side of the heating bag 32 away from the ventilation pipe 1 is fixedly connected to the detection chamber 3 through the bracket. The heating bag 32 is connected to the outside world and the pushing bag 42 through the exchange pipe 7. A second one-way valve 34 is provided between the heating bag 32 and the outside world. The second one-way valve 34 can only allow outside air to flow unidirectionally into the heating bag 32. A first one-way valve 33 is provided between the heating bag 32 and the pushing bag 42 through the exchange pipe 7. The first one-way valve 33 can only allow air in the heating bag 32 to flow unidirectionally into the pushing bag 42. When the heating bag 32 is in a normal state, there is a gap between the cam 31 and the heating bag 32. When the heating bag 32 is in a compressed state, the cam 31 abuts against the heating bag 32.
[0042] The testing chamber 3 and the fumigation head 2 are also fitted with a vibrating plate 6 with a clearance. One end of the vibrating plate 6 is located between the cam 31 and the testing chamber 3. The inner wall of the fumigation head 2 is fixedly connected to the mounting block 5. A moving block 51 is slidably fitted on the mounting block 5. The end of the moving block 51 away from the mounting block 5 is rotatably fitted with the heat exchange plate 4. The pushing bag 42 is located between the bottom of the heat exchange plate 4 and the mounting block 5. The moving block 51 is fixedly connected to the end of the vibrating plate 6 away from the cam 31.
[0043] The fumigation head 2 has several heat dissipation holes 21, and a filter screen 23 is provided between the heat dissipation holes 21 and the exchange pipe 7; the end of the exchange pipe 7 away from the heating bag 32 is connected to the outside through the filter screen 23.
[0044] It also includes a control panel, which is used to adjust the rotation speed of the power components based on real-time temperature data, and the heat exchange plate 4 adjusts the expansion of the push bag 42 according to the gas output of the heating bag 32.
[0045] The specific implementation process is as follows:
[0046] First, the fumigation head 2 is preheated to ensure temperature uniformity during the delivery of atomized medicine, which facilitates drug fumigation treatment of the skin covered by the fumigation head 2.
[0047] During the delivery of the atomized medicine through the ventilation pipe 1, the real-time temperature of the atomized medicine is measured by a first temperature sensor. The control panel adjusts the rotation speed of the power component based on the real-time temperature. As the power component drives the cam 31 to rotate continuously, the cam 31, eccentrically connected to the output shaft of the power component, continuously contacts or separates from the heating bag 32. This allows the heating bag 32 to continuously draw in outside air through the first one-way valve 33 and the second one-way valve 34 on the exchange pipe 7. The air inside the heating bag 32 then continuously fills the pushing bag 42 through the exchange pipe 7, causing the pushing bag 42 to move the heat exchange plate 4. The faster the rotation speed of the power component, the greater the amount of gas expelled from the heating bag 32 through the exchange pipe 7, resulting in a greater expansion amplitude of the pushing bag 42. This increases the degree of blockage inside the fumigation head 2 by the heat exchange plate 4, extending the cooling time of the atomized medicine and reducing the risk of burns when the atomized medicine comes into contact with the skin.
[0048] Since the heating bag 32 comes into contact with the liquid vapor discharged from the ventilation pipe 1 immediately, the air inside the heating bag 32 is continuously heated. When the volume inside the heating bag 32 does not change, based on the ideal gas law PV=nRT, when the volume of the heating bag 32 remains constant, the internal air temperature (T) increases, and the pressure (P) must increase to maintain the equilibrium. Therefore, the higher the temperature of the atomized liquid at the current time, the higher the air pressure inside the heating bag 32. When the air is delivered to the push bag 42 through the exchange pipe 7, the high-pressure air diffuses rapidly to quickly fill the internal space of the push bag 42, so that the push bag 42 can expand more rapidly per unit time. This increases the lifting distance of the push bag 42 relative to the heat exchange plate 4, making it easier for the heating plate to form staggered and segmented spaces inside the fumigation head 2, so as to reduce the direct contact of the excessively hot atomized liquid with the skin surface and reduce the risk of burns.
[0049] Simultaneously, as the power component drives the cam 31 to rotate, the reciprocating expansion of the push bladder 42 re-vibrates and disperses the atomized medicine on the heat exchange plate 4, reducing the accumulation of the atomized medicine due to continuous condensation. The cam 31 continuously contacts the vibrating plate 6 placed on the inner wall of the detection chamber 3, causing the vibrating plate 6 to drive the moving block 51 to slide on the mounting block 5. During the repeated rotation of the cam 31, the vibrating plate 6 continuously drives the heat exchange plate 4 on the moving block 51 to vibrate back and forth, increasing the vibration amplitude at the end of the heat exchange plate 4 away from the moving block 51. Based on the lever principle, this strengthens the vibration force at the end of the heat exchange plate 4 away from the moving block 51, thereby enhancing the vibration and dispersion of the atomized medicine inside the fumigation head 2 and the medicine adhering to the surface of the heat exchange plate 4, thus reducing the accumulation of the atomized medicine.
[0050] During the process of the heating bladder 32 drawing in outside air through the exchange tube 7, the filter screen 23 filters the outside air, reducing the occurrence of impurities and dust in the outside air entering the exchange tube 7 and the interior of the heating bladder 32 and causing blockages. This reduces the need for internal cleaning, facilitates long-term use, and allows for easy mixing of outside air with the hot air inside the heating bladder 32. It also reduces the occurrence of condensation of the atomized medicine when the outside air comes into contact with the atomized medicine discharged from the ventilation tube 1.
[0051] Example 2:
[0052] The difference from Embodiment 1 is that springs are fixedly connected to both sides of the movable block 51, and the end of the spring away from the movable block 51 is fixedly connected to the mounting block 5.
[0053] The specific implementation process is as follows: During the vibration of the heat exchange plate 4 driven by the moving block 51, the springs on both sides of the moving block 51 are squeezed by the moving block 51. During the rotation of the cam 31, when the cam 31 stops squeezing and resetting the vibrating plate 6, the springs that applied pressure release their elasticity and push the moving block 51 to move, so that the heat exchange plate 4 on the moving block 51 can still maintain vibration, thereby reducing the occurrence of condensation of atomized drug liquid during the static placement of the heat exchange plate 4, so as to ensure the uniform dispersion of atomized drug and improve the drug absorption effect.
[0054] Example 3:
[0055] The difference from Embodiment 2 is that the length of the heat exchange plate 4 gradually increases along the gas delivery direction of the ventilation pipe 1, and an extension plate 41 is fixedly connected to the side of the heat exchange plate 4 near the ventilation pipe 1.
[0056] The specific implementation process is as follows: The length of the heat exchange plate 4 is maintained to ensure the dividing effect of the heat exchange plate 4 on the inside of the fumigation head 2, maintain the movement time and movement length of the atomized medicine, facilitate the slow cooling of the atomized medicine during the movement process, and maintain the temperature stability during the contact process between the skin and the atomized medicine.
[0057] Example 4:
[0058] The difference from Embodiment 3 is that the push bladder 42 is connected to a discharge pipe 71, which is located inside the moving block 51; and the moving block 51 has a mating cavity, in which a squeezing block 43 is rotatably fitted. The squeezing block 43 is fixedly connected to the heat exchange plate 4, and a rotating shaft is rotatably fitted at the connection between the heat exchange plate 4 and the moving block 51. The heat exchange plate 4 is fixedly connected to the squeezing block 43 through the rotating shaft, and one end of the discharge pipe 71 is located inside the mating cavity; when the push bladder 42 is in a contracted state, the squeezing block 43 is separated from the discharge pipe 71, and when the push bladder 42 is fully expanded, the squeezing block 43 abuts against the discharge pipe 71.
[0059] The specific implementation process is as follows: During the expansion of the push bladder 42 based on the pressurized air transported inside the exchange tube 7, the rotation of the heat exchange plate 4 drives the compression block 43 to rotate. The compression block 43 compresses and seals the discharge tube 71, reducing the discharge time of the push bladder 42 through the discharge tube 71. During the continuous air intake of the exchange tube 7, the position of the push bladder 42 relative to the heat exchange plate 4 is maintained, thereby extending the flow distance and flow time of the atomized medicine inside the fumigation head 2, performing cooling treatment, and maintaining the temperature stability inside the fumigation head 2.
[0060] Example 5:
[0061] The difference from Embodiment 4 is that the control panel is also electrically connected to a second temperature sensor and an electric heating tube. The second temperature sensor is located on the heat exchange plate 4, and the heat exchange plate 4 with the second temperature sensor is located on the side of the heat exchange plate 4 away from the detection chamber 3. The electric heating tube is located on the side of the filter screen 23 close to the exchange tube 7, and the electric heating tube is arranged in a ring around the fumigation head 2.
[0062] The second temperature sensor is used to measure the comparative temperature data around the heat exchanger 4 in real time. The control panel is also used to compare the real-time temperature data with the set standard range. If the real-time temperature is greater than the standard range, the step temperature between the real-time temperature and the maximum value of the standard range is calculated, and the corresponding speed adjustment command is obtained to the power unit based on the step temperature. If the real-time temperature is within the standard range, a standby command is sent to the power unit. If the real-time temperature is less than the standard range, a start command is sent to the electric heating tube until the real-time temperature is consistent with the standard range.
[0063] Meanwhile, the control panel compares the comparison temperature data with the burn temperature. If the comparison temperature data is greater than the burn temperature, the control panel displays an alarm command; if the comparison temperature data is less than the burn temperature, it determines whether the comparison temperature data is within the standard range. If the comparison temperature data is within the standard range, it sends a standby command to the electric heating element; if the comparison temperature data is not within the standard range, it sends a start command to the electric heating element.
[0064] For example, by comparing real-time temperature data with a standard range, the temperature of the atomized medicine delivered through ventilation duct 1 can be determined. This allows for the activation of the electric heating element for heating adjustment, or control of the power component's rotation speed. The gas delivered through heating bladder 32 regulates the expansion of push bladder 42, causing push bladder 42 to drive heat exchange fins 4 to segment the interior of fumigation head 2. This verifies the delivery distance and time of the atomized medicine, maintaining the stability of the medicine's temperature. If the atomized medicine is within the standard range, it means that the atomized medicine is less affected by factors such as gradual condensation during delivery through ventilation duct 1 (e.g., the influence of seasonal ambient temperature on the delivery through ventilation duct 1 and the temperature of the atomized medicine generated by the fumigation machine). Therefore, the impact of condensation and aggregation of the atomized medicine is minimal, ensuring the particle dispersion and temperature of the atomized medicine.
[0065] Simultaneously, the second temperature sensor compares the temperature data of the heat exchange plate 4 near the skin to determine the contact temperature of the atomized medicine in the fumigation head 2 when it comes into contact with the skin. If the comparison temperature is higher than the burn temperature, an alarm is triggered in time to stop the fumigation, reducing the risk of burns to the patient during the temperature adjustment of the atomized medicine. If the comparison temperature is lower than the burn temperature, it is used to determine whether the comparison temperature is within the standard range, thereby maintaining the fumigation temperature inside the fumigation head 2 within the standard range to ensure the drug absorption effect.
[0066] In another embodiment, the control panel is also used to calculate the difference between real-time temperature data and comparative temperature data, compare the difference with a set change value, and if the difference is greater than the change value, display an abnormal operation command; if the difference is less than or equal to the change value, display a normal operation command.
[0067] For example, during the adjustment of the heat exchange plate 4 inside the fumigation head 2, if the fumigation head 2 is not preheated or if the atomized medicine is delivered through the ventilation pipe 1, a large difference may occur between the real-time temperature data and the comparison temperature data. In such cases, an alarm will be triggered to remind the user to pause or make adjustments in a timely manner, so as to ensure the fumigation effect or the risk of burns that may occur during the fumigation process.
[0068] Example 6:
[0069] The difference from Example 5 is that a suction cup 22 is fixedly connected to the end of the fumigation head 2 away from the detection chamber 3, and the suction cup 22 is arranged circumferentially around the outer edge of the fumigation head 2.
[0070] The specific implementation process is as follows: When the fumigation head 2 needs to be attached to the skin surface for fixed-point fumigation, the fumigation head 2 is manually pressed to adhere to the skin surface by the suction cup 22. After the air inside the suction cup 22 is discharged, the stable adsorption effect of the suction cup 22 is used to keep the fumigation head 2 continuously fumigating the fixed position.
[0071] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
