Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and in particular relates to an integrated drug delivery device and a method of use. Background Art

[0002] With the rapid development of society, people's living standards are getting higher and higher, and the number of people suffering from chronic diseases and sub-health is increasing, which seriously threatens people's physical and mental health. For the treatment of chronic diseases, long-term medication is usually required, which has great side effects, is not safe, has a long treatment cycle, a short duration of drug effect, and poor treatment effect. Sub-health diseases cannot be detected using ordinary laboratory equipment, and Western medicine does not have corresponding treatment plans. Clinically, it has been shown that traditional Chinese medicine rehabilitation therapy can alleviate or even cure sub-health diseases. At present, there is a shortage of traditional Chinese medicine and traditional Chinese medicine therapists, and the physical therapy process is time-consuming and labor-intensive. With the development of science and technology, in order to solve these problems, the treatment method of acupoint medication has emerged.

[0003] However, the conventional method of acupuncture point drug administration is to stick a cotton pad (with liquid medicine attached to the cotton pad) on the acupuncture point, and the absorption of the medicine at the acupuncture point is slow, resulting in poor treatment effect. Summary of the invention

[0004] In response to the above defects or improvement needs of the prior art, the present invention provides an integrated drug delivery device and a method of use, the purpose of which is not only to absorb drugs through periodically changing negative pressure, but also to adjust the treatment cycle by combining the heart rate, ultimately allowing the drugs to be more efficiently absorbed by the acupuncture points and enter the blood circulation system more quickly.

[0005] To achieve the above-mentioned object, in a first aspect, the present invention provides an integrated drug delivery device, the integrated drug delivery device comprising a drug delivery head and a control component;

[0006] The drug delivery head comprises a shell, a silicone sleeve and a support plate, wherein the support plate is inserted at one end of the shell to squeeze the cotton sheet, the silicone sleeve comprises an outer rubber sleeve and an inner rubber sleeve, one end of the inner rubber sleeve is sleeved on one end of the shell, one end of the outer rubber sleeve is fixed on the outer peripheral wall of one end of the inner rubber sleeve, and the other end of the outer rubber sleeve extends outward and is spaced from the other end of the inner rubber sleeve to form a negative pressure chamber;

[0008] Optionally, the dosing head further comprises a heating plate, the heating plate is fixed on the supporting plate, and the heating plate and the cotton sheet are located on both sides of the supporting plate.

[0009] Optionally, the dosing head further comprises a vibration plate, wherein the vibration plate is fixed on the support plate and spaced apart from the heating plate, and the vibration plate and the cotton sheet are located on both sides of the support plate.

[0010] Optionally, the drug delivery head further comprises a current conductor, and the current conductor is inserted into the support plate.

[0011] Optionally, the control component further includes a solenoid valve, and the solenoid valve is connected between the reflux bottle and the negative pressure pump.

[0012] Optionally, the control module is configured such that when the heart rate belt detects that the patient's heart rate is in a slow range, the control module controls the pressure of the negative pressure chamber during the pressure-maintaining stage to be 12-15Mpa; when the heart rate belt detects that the patient's heart rate is in a normal range, the control module controls the pressure of the negative pressure chamber during the pressure-maintaining stage to be 8-12Mpa; when the heart rate belt detects that the patient's heart rate is in a fast range, the control module controls the pressure of the negative pressure chamber during the pressure-maintaining stage to be 5-8Mpa.

[0013] Optionally, the slow range is less than 60 times / minute, the normal range is 60-100 times / minute, and the fast range is greater than 100 times / minute.

[0014] Optionally, the threshold number of times is 7-20 times.

[0015] Optionally, the control module includes a main control board and a function board, the function board is located on the main control board and electrically connected to the main control board, the heart rate belt is electrically connected to the main control board, and the pressure sensor and the negative pressure pump are electrically connected to the function board respectively.

[0016] In a second aspect, the present invention provides a method for using an integrated drug delivery device, the method for using the integrated drug delivery device being based on the drug delivery device of the first aspect, and the method for using the integrated drug delivery device comprising:

[0017] Placing a cotton sheet on the patient's acupuncture point, and placing the support plate on the cotton sheet, wherein the silicone sleeve is located on the outer periphery of the cotton sheet;

[0018] The heart rate belt is placed on the patient's pulse, and the patient's pulse is obtained in real time through the heart rate belt;

[0019] The negative pressure pump is started, and the negative pressure of the negative pressure chamber is periodically adjusted by the control module, so that the pressure of the negative pressure chamber passes through a pressure-increasing stage, a pressure-maintaining stage, and a pressure-reducing stage in sequence.

[0020] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0021] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects:

[0022] For an integrated drug delivery device provided by an embodiment of the present invention, since one end of the inner rubber sleeve is sleeved on one end of the shell, one end of the outer rubber sleeve is fixed on the outer peripheral wall of one end of the inner rubber sleeve, and the other end of the outer rubber sleeve extends outward and is spaced from the other end of the inner rubber sleeve to form a negative pressure cavity, when negative pressure is provided to the negative pressure cavity, both the outer rubber sleeve and the inner rubber sleeve can be deformed, and the support plate is moved toward the acupuncture point to squeeze the cotton sheet, so that the cotton sheet can be closely attached to the acupuncture point, which is convenient for the acupuncture point to absorb the drug. In addition, as the negative pressure in the negative pressure cavity continues to change, the drug's permeability to the skin is stronger.

[0023] When treating the patient, first place the cotton sheet on the patient's acupuncture point, and place the support plate on top of the cotton sheet, with the silicone sleeve located on the periphery of the cotton sheet and in contact with the skin. Then, place the heart rate belt on the patient's pulse, and obtain the patient's pulse in real time through the heart rate belt. During the human body's blood circulation, the drug reaches the lesion through the blood circulation, and the basis of blood circulation is the heart's pulse. Therefore, the subsequent treatment cycle is adjusted by combining the heart rate speed (that is, a pressurization stage, a pressure maintenance stage and a pressure reduction stage corresponding to the negative pressure are a treatment cycle), so as to perform adaptive treatment for different patients (different pulses), so that the drug is more efficiently absorbed by the acupuncture points and enters the blood circulation system faster. Finally, start the negative pressure pump, and adjust the negative pressure of the negative pressure chamber periodically through the control module. During the treatment process, the control module collects the patient's pulse in real time. In addition, the control module simultaneously obtains the pressure of the reflux bottle in real time and controls the power or start and stop of the negative pressure pump, so that the pressure in the negative pressure chamber finally passes through the pressurization stage, the pressure maintaining stage and the pressure reduction stage in sequence, thereby achieving periodic stimulation and continuous pressure maintaining stimulation of the acupoints through periodic pressure changes and pressure maintaining for a certain period of time, further promoting the absorption of drugs by the acupoints and improving the treatment effect.

[0024] That is to say, the integrated drug delivery device provided by the embodiment of the present invention can not only absorb drugs through periodically changing negative pressure, but also adjust the treatment cycle by combining the heart rate, ultimately allowing the drugs to be more efficiently absorbed by the acupuncture points and enter the blood circulation system faster.

[0037] Example:

[0038] Figure 1 is a schematic diagram of the structure of an integrated drug delivery device provided by an embodiment of the present invention. Figure 1 As shown, the integrated drug delivery device includes a drug delivery head 1 and a control component 2.

[0039] Figure 2 is a schematic diagram of the structure of a drug delivery head provided by an embodiment of the present invention, Figure 3 is a cross-sectional view of a housing provided by an embodiment of the present invention, Figure 4 is a schematic diagram of the structure of the silicone sleeve provided by an embodiment of the present invention, combined with Figure 2-Figure 4 As shown, the drug delivery head 1 includes a shell 11, a silicone sleeve 12 and a support plate 13. The support plate 13 is inserted at one end of the shell 11 to squeeze the cotton sheet. The silicone sleeve 12 includes an outer rubber sleeve 121 and an inner rubber sleeve 122. One end of the inner rubber sleeve 122 is sleeved on one end of the shell 11, one end of the outer rubber sleeve 121 is fixed on the outer peripheral wall of one end of the inner rubber sleeve 122, and the other end of the outer rubber sleeve 121 extends outward and is spaced from the other end of the inner rubber sleeve 122 to form a negative pressure chamber 14.

[0040] The control component 2 includes a heart rate belt 21, a negative pressure pump 22, a reflux bottle 23, a pressure sensor 24 and a control module 25. The heart rate belt 21 is used to measure the patient's heart rate. The negative pressure chamber 14, the reflux bottle 23 and the negative pressure pump 22 are connected in sequence. The pressure sensor 24 is used to detect the pressure in the reflux bottle 23. The control module 25 is electrically connected to the pressure sensor 24, the negative pressure pump 22 and the heart rate belt 21 respectively. The control module 25 is used to control the negative pressure pump 22 based on the patient's heart rate data obtained by the heart rate belt 21 and based on the pressure sensor 24, so as to periodically adjust the negative pressure of the negative pressure chamber 14 based on the time corresponding to the threshold number of pulse beats of the patient (that is, a treatment cycle), wherein the negative pressure of the negative pressure chamber 14 passes through a pressurization stage, a pressure maintaining stage and a pressure reduction stage in sequence.

[0041] For an integrated drug delivery device provided by an embodiment of the present invention, since one end of the inner rubber sleeve 122 is sleeved on one end of the housing 11, one end of the outer rubber sleeve 121 is fixed on the outer peripheral wall of one end of the inner rubber sleeve 122, and the other end of the outer rubber sleeve 121 extends outward, and is spaced from the other end of the inner rubber sleeve 122 to form a negative pressure chamber 14, so that when negative pressure is provided to the negative pressure chamber 14, both the outer rubber sleeve 121 and the inner rubber sleeve 122 can be deformed, and the support plate 13 is moved toward the acupuncture point to squeeze the cotton sheet, so that the cotton sheet can be closely attached to the acupuncture point, which is convenient for the acupuncture point to absorb the drug. In addition, as the negative pressure in the negative pressure chamber 14 changes continuously, the drug has stronger permeability to the skin.

[0042] When treating a patient, first place the cotton sheet on the patient's acupuncture point, and place the support plate 13 on top of the cotton sheet, and the silicone sleeve 12 is located on the periphery of the cotton sheet and in contact with the skin. Then, the heart rate belt 21 is set on the patient's pulse, and the patient's pulse is obtained in real time through the heart rate belt 21. During the human blood circulation process, the drug reaches the lesion through the blood circulation, and the basis of blood circulation is the pulse of the heart. Therefore, the treatment cycle is subsequently adjusted by combining the heart rate speed (that is, a pressurization stage, a pressure maintenance stage and a pressure reduction stage corresponding to the negative pressure are a treatment cycle), so as to perform adaptive treatment for different patients (different pulses), so that the drug is more efficiently absorbed by the acupuncture points and enters the blood circulation system faster. Finally, start the negative pressure pump 22, and the negative pressure of the negative pressure chamber 14 is periodically adjusted correspondingly by the control module 25. During the treatment process, the control module 25 collects the patient's pulse in real time. In addition, the control module 25 simultaneously obtains the pressure of the reflux bottle 23 in real time and controls the power or start and stop of the negative pressure pump 22, so that the pressure of the negative pressure chamber 14 finally passes through the pressurization stage, the pressure maintaining stage and the pressure reduction stage in sequence, thereby achieving periodic stimulation and continuous pressure maintaining stimulation of the acupoints through periodic pressure changes and pressure maintaining for a certain period of time, further promoting the absorption of drugs by the acupoints and improving the treatment effect.

[0043] That is to say, the integrated drug delivery device provided by the embodiment of the present invention can not only absorb drugs through periodically changing negative pressure, but also adjust the treatment cycle by combining the heart rate, ultimately allowing the drugs to be more efficiently absorbed by the acupuncture points and enter the blood circulation system faster.

[0044] It is easy to understand that the acupoints are not on the body surface but at a certain depth below the body surface, and the depth varies depending on fatness or thinness. Different negative pressures can make the cotton sheet at different heights, thereby adjusting the distance between the cotton sheet and the acupoints. Moreover, when the negative pressure value changes according to a regular pattern, the stimulation of the acupoints by the dosing head 1 will also change regularly, and the treatment effect will be better. In addition, traditional Chinese medicine theory and clinical experiments have proved that the absorption effect of the acupoints on the drug is better when the stimulation frequency is closer to the heart rate fluctuation.

[0045] For example, the slower the patient's heart rate, the longer the time corresponding to the threshold number of pulse beats, and the slower the blood circulation and metabolic rate. Therefore, the corresponding treatment cycle is longer, which is more conducive to the absorption of drugs by the acupoints.

[0046] It is easy to understand that during the treatment process, the reflux bottle 23 can prevent the drug from flowing back into the negative pressure pump 22, thereby preventing the negative pressure pump 22 from being damaged.

[0047] Exemplarily, the negative pressure chamber 14, the reflux bottle 23 and the negative pressure pump 22 are connected by a hose. In addition, the housing 11 has an inner cavity and a first through hole 111 connected to the inner cavity, and the inner rubber sleeve 122 has a second through hole 1221. The inner cavity is connected to the negative pressure chamber 14 through the first through hole 111 and the second through hole 1221, so that the negative pressure chamber 14 is evacuated by the negative pressure pump 22.

[0048] Exemplarily, the bottom of the outer rubber sleeve 121 and the inner rubber sleeve 122 may be arc-shaped so as to better fit the human skin. The bottom of the inner rubber sleeve 122 extends out of the support plate 13, and its inner wall has a plurality of elastic protrusions 1222 arranged at intervals, so as to cooperate with the support plate 13 to clamp the cotton sheet.

[0049] Continue to see Figure 2 and Figure 3 The dosing head 1 further includes a heating plate 15 , which is fixed on the supporting plate 13 , and the heating plate 15 and the cotton sheet are located on both sides of the supporting plate 13 .

[0050] In the above embodiment, the heating plate 15 heats the cotton sheet by increasing the temperature to accelerate the volatilization of the drug and the absorption of the effective drug by the skin acupuncture points.

[0051] Exemplarily, the heating plate 15 is bonded in parallel to the support plate 13 , and the heating plate 15 transfers heat to the support plate 13 during the heating process, and the support plate 13 finally transfers heat to the cotton sheet. The control module 25 is electrically connected to the heating plate 15 .

[0052] In this embodiment, the dosing head 1 further includes a vibration plate 16 , which is fixed on the support plate 13 and spaced apart from the heating plate 15 . The vibration plate 16 and the cotton sheet are located on both sides of the support plate 13 .

[0053] In the above embodiment, the vibration plate 16 reciprocates near the equilibrium position by vibrating, playing the role of ultrasound, causing rhythmic density changes inside the medium. This density change forms a pressure change, which can produce a fine massage effect on human tissue cells and promote the absorption of drugs by acupuncture points.

[0054] Exemplarily, the vibration plate 16 is also bonded to the support plate 13. The vibration plate 16 is annular, located at the periphery of the heating plate 15, and spaced apart from the heating plate 15. The control module 25 is electrically connected to the vibration plate 16.

[0055] In addition, the drug delivery head 1 further includes a current conductor (not shown), which is inserted into the support plate 13. The current conductor can provide an electrical signal, thereby providing electrical stimulation to the acupoints, and can also promote the absorption of drugs by the acupoints.

[0056] It should be noted that different types of electric current have different main physiological effects on the human body. Direct current is a current with a constant direction. It can change the distribution of ions in the body and adjust the body's functions. It is often used for drug ion introduction. Low and medium frequency currents stimulate nerve and muscle contraction, reduce pain thresholds, and relieve adhesions. They are often used for neuromuscular diseases such as injuries and inflammation. High frequency electricity promotes circulation with its thermal effect and thermal external effect on the human body, reduces inflammation and edema, stimulates tissue regeneration, and relieves pain. It is often used to treat injuries, inflammatory pain syndromes, and high-power high frequency electricity can be used for heating to treat cancer. The main function of static electricity is to regulate the central nervous system and plant functions. It is often used for neurosis, early hypertension, and menopausal syndrome.

[0057] Exemplarily, the control module 25 is electrically connected to the current conductor. The support plate 13 is a metal structure, preferably, the support plate 13 is a steel structure, so as to better transmit thermal stimulation, ultrasonic stimulation and electrical stimulation.

[0058] That is to say, the drug delivery device integrates heat therapy, electrotherapy, ultrasound and comprehensive treatment of acupuncture points with cotton pads.

[0059] See also Figure 1 The control component 2 also includes a solenoid valve 26, which is connected between the reflux bottle 23 and the negative pressure pump 22. The solenoid valve 26 can control the on-off between the reflux bottle 23 and the negative pressure pump 22.

[0060] In this embodiment, the control module 25 includes a main control board 251 and a function board 252. The function board 252 is located on the main control board 251 and is electrically connected to the main control board 251. The heart rate belt 21 is electrically connected to the main control board 251. The pressure sensor 24 and the negative pressure pump 22 are electrically connected to the function board 252 respectively.

[0061] In the above embodiment, the main control board 251 mainly plays the role of acquiring and identifying the data of the heart rate belt 21 and the pressure data in the reflux bottle 23, and generates a corresponding control signal to the function board 252, and the function board 252 transmits the control signal to the negative pressure pump 22.

[0062] Exemplarily, the main control board 251 is electrically connected to the heating plate 15, the vibration plate 16 and the current conducting wires, respectively.

[0063] It should be noted that the main control board 251 is also electrically connected to the buzzer. When the heart rate belt 21 detects that the patient's heart rate is too low or too high, the main control board 251 controls the buzzer to generate an alarm signal.

[0064] In one implementation of the present invention, the control module 25 is configured such that when the heart rate belt 21 detects that the patient's heart rate is in a slow range, the control module 25 controls the pressure of the negative pressure chamber 14 during the pressure-maintaining stage to be 12-15Mpa; when the heart rate belt 21 detects that the patient's heart rate is in a normal range, the control module 25 controls the pressure of the negative pressure chamber 14 during the pressure-maintaining stage to be 8-12Mpa; when the heart rate belt 21 detects that the patient's heart rate is in a fast range, the control module 25 controls the pressure of the negative pressure chamber 14 during the pressure-maintaining stage to be 5-8Mpa.

[0065] It is easy to understand that when the patient's heart rate is slow, the blood circulation and metabolic rate are slower. At this time, a larger negative pressure should be provided to provide greater stimulation, so that the cotton sheet is closer to the acupoints and promote the absorption of drugs by the acupoints. Conversely, when the patient's heart rate is fast, the blood circulation and metabolic rate are faster. In order to avoid excessive stimulation causing adverse reactions in patients, a smaller negative pressure should be provided to meet the absorption of drugs by the acupoints.

[0066] Exemplarily, the slow heart rate range is less than 60 beats / minute, the normal heart rate range is 60-100 beats / minute, and the fast heart rate range is greater than 100 beats / minute.

[0067] In this embodiment, the threshold number of times is 7-20 times, preferably 7 times.

[0068] Exemplarily, the time when 7 pulse beats of a patient are collected by the heart rate belt 21 corresponds to T. At this time, within the time of 0-T / 3, the pressure in the negative pressure chamber 14 is in the pressurization stage, and the negative pressure increases to the pressure of the pressure-maintaining stage; within the time of T / 3-(2T) / 3, the pressure in the negative pressure chamber 14 is always in the pressure-maintaining stage, and the pressure is maintained. This stage has the greatest stimulation to the acupoints, and the acupoints absorb the drugs fastest; within the time of (2T) / 3-T, the pressure in the negative pressure chamber 14 is in the pressure-reducing stage, and the negative pressure drops to normal pressure, thereby completing a treatment cycle.

[0069] It should be noted that when the drug delivery device is in use, if the patient does not use the heart rate belt 21 (i.e., the patient's pulse data is not collected at this time), the negative pressure pump 22 will work according to a treatment cycle of 6 seconds, that is, 0-2 seconds is the pressurization stage; 2-4 seconds is the pressure maintenance stage; 4-6 seconds is the pressure reduction stage, so that treatment can be completed even in emergency situations.

[0070] Exemplarily, the drug delivery device further comprises a display screen 3, which is electrically connected to the main control board 251, and is used to display measurement data and manually input corresponding control instructions.

[0071] Figure 5 is a flow chart of a method for using an integrated drug delivery device provided by an embodiment of the present invention. Figure 5 As shown, the method of use is based on the above-mentioned drug delivery device, and the method of use includes:

[0072] S1. Place a cotton sheet on the patient's acupuncture point, and place the support plate 13 on top of the cotton sheet, with the silicone sleeve 12 located on the outer periphery of the cotton sheet.

[0075] The method for using the integrated drug delivery device provided in the embodiment of the present invention can not only absorb drugs through periodically changing negative pressure, but also adjust the treatment cycle by combining the heart rate, ultimately allowing the drugs to be more efficiently absorbed by the acupuncture points and enter the blood circulation system faster.
