Description

Technical Field

[0001] The present invention relates to the technical field of transdermal drug delivery, in particular to a hot compress drug delivery system and method. Background Art

[0002] Transdermal drug delivery system is a method of delivering drugs into the body through the skin. This method avoids the first-pass effect in the liver and gastrointestinal side effects that may be caused by oral administration, while providing continuous and stable drug release. However, traditional transdermal drug delivery systems face the problems of low drug penetration efficiency and large individual differences. Hot compress, as a means of promoting drug penetration, can enhance the transdermal absorption of drugs by dilating blood vessels, increasing skin blood flow and reducing skin resistance.

[0003] Traditional hot compress uses a hot towel or a general heating element to wrap the part to be heated. The towel hot compress heats by thermal convection, which is unstable and uneven, and the heating time is limited. A hot compress drug guide system and method are proposed. Heat can be transferred by heat conduction or thermal radiation to heat stably and evenly, and the heating time can last for several hours, so as to ensure that the transdermal drug delivery absorption rate of the drug package is greatly improved.

Select two specific values ​​within the drug package concentration monitoring range as trigger points for controlling the heating unit, which are defined as a first set value and a second set value: the first set value represents a higher concentration threshold, and the second set value represents a lower concentration threshold;

[0015] S4.2, when it is detected that the concentration of the drug package reaches or exceeds the first set value, the heating unit stops heating and enters the insulation mode to keep the concentration of the drug package stable within the set range to avoid abnormal concentration increase caused by overheating;

[0016] S4.3. When it is detected that the concentration of the medicine package is lower than the second set value: start the heating unit to increase the temperature of the medicine package to make the concentration return to the set safety range.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 In an embodiment of the present invention, a hot compress medicine guiding method comprises the following steps:

[0027] S1, determine the type of medicine package 5;

[0028] S2, setting initial parameters: according to the type of drug package 5 determined in S1, setting the monitoring range of the concentration monitoring unit 4, and the heating temperature and working time of the heating unit 2;

[0029] S3, select a heat transfer method: based on the wearing position of the medicine package 5, decide to use heat conduction or heat radiation to transfer heat, so as to ensure that the selected heat transfer method can continuously maintain the heat of the medicine package 5 without being affected by other factors;

[0030] The specific steps of step 3 are as follows:

[0031] S3.1, when the heating unit 2 is in direct contact with the medicine package 5, heat is directly transferred from the heating unit 2 to the medicine package 5 by heat conduction;

[0032] S3.2 When the heating unit 2 and the medicine package 5 are not in direct contact, heat is transferred from the heating unit 2 to the medicine package 5 by thermal radiation.

[0033] S4. Real-time monitoring of drug concentration and temperature adjustment: The drug concentration is continuously monitored by the concentration monitoring unit 4, and the control unit 1 dynamically adjusts the temperature of the heating unit 2 according to the concentration monitoring result to maintain the drug concentration within the set range.

[0034] S4.1. Select two specific values ​​within the concentration monitoring range of the drug package 5 as trigger points for controlling the heating unit 2, which are defined as a first set value and a second set value: the first set value represents a higher concentration threshold, and the second set value represents a lower concentration threshold;

[0035] S4.2, when it is detected that the concentration of the medicine package 5 reaches or exceeds the first set value, the heating unit 2 stops heating and enters the heat preservation mode to keep the concentration of the medicine package 5 stable within the set range to avoid abnormal concentration increase caused by overheating;

[0036] S4.3, when it is detected that the concentration of the medicine package 5 is lower than the second set value: start the heating unit 2 to increase the temperature of the medicine package 5 to promote the concentration to return to the set safety range.

[0037] A hot compress medicine guiding system comprises a control unit 1 and a heating unit 2 controlled by the control unit 1, wherein the control unit 1 monitors the temperature of a medicine package 5 via a temperature monitoring unit 3, and the control unit 1 monitors the medicine concentration of the medicine package 5 via a concentration monitoring unit 4, and is configured to adjust the heating temperature in real time under different drug concentration requirements.

[0038] Specifically, the device transfers heat by heat conduction or heat radiation by selecting and using materials with excellent electrical and thermal conductivity; the control unit is used to adjust the temperature and working time of the heating unit; the drug concentration monitoring unit is used to monitor the concentration of drugs to be absorbed transdermally, and the monitoring device sets a value of 0-100 to monitor the drug concentration in real time; for example, a medicine package for treating knee pain, the drug concentration needs to be maintained at about 80 to meet the needs of continuous hot compress and drug conduction for 4 hours, and the effect is the best. Initially, the drug package 5 is heated by the heating unit 2, and the drug concentration monitoring unit 4 monitors in real time. When the drug concentration reaches 80, the heating unit 2 stops heating and enters the insulation state. When the concentration monitoring unit 4 monitors the concentration to be lower than about 70, the heating unit 2 starts heating to form a closed loop, which greatly improves the absorption rate of transdermal drug delivery and significantly improves the treatment effect.

[0039] See also Figure 2 In one embodiment, in this embodiment, preferably, the control unit 1 includes a temperature control module, an overheating protection module and a timing shutdown module, and the temperature control module, the overheating protection module and the timing shutdown module are all connected to the heating unit 2.

[0040] Specifically, the overheat protection module and the timed shutdown module enable the system to have overheat protection and timed shutdown functions to prevent burns and overheating, and the temperature control module can control the heating unit 2. The heating unit 2 can use PI heating film, graphene, carbon fiber heating element or iron powder and other materials with good electrical and thermal conductivity, and generate heat through electric current heating. On the one hand, the temperature control of the medicine package 5 is more accurate, and on the other hand, it is low in cost and simple to operate. The control unit 1 monitors the temperature of the heating unit through a temperature sensor, and adjusts the heating power through a microprocessor to maintain the set treatment temperature. In addition, the device can be used for the knees, neck, shoulders, hands, elbows, waist, spine, feet, abdomen and other positions, and the design should conform to ergonomic principles to ensure wearing comfort and convenience.

[0041] See also Figure 1 In one embodiment, in this embodiment, preferably, the temperature monitoring unit is composed of a temperature sensor, and the temperature sensor is connected to the control unit. Further, the heating power is adjusted by a microprocessor to maintain the set treatment temperature.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
