Description

An ultrasonic conductivity meter with a temperature control device

technical field

The utility model relates to an ultrasonic conductivity meter with a temperature control device, which belongs to the technical field of ultrasonic conductivity transdermal drug delivery.

Background technique

With the development of modern medicine, the ultrasonic conductivity meter has been introduced into the field of transdermal drug delivery. The ultrasonic electrode probe can simultaneously output ultrasonic waves and intermediate frequency electricity, and can use instantaneous high-voltage pulses to create electrical holes in the stratum corneum of the skin to promote drug delivery in the skin and skin. Penetration, transmission and absorption in tissues make up for the shortcomings of traditional transdermal drug delivery methods, such as poor penetration effect and low drug utilization rate.

Ultrasonic waves can enter deep tissue cells of the human body. Drugs, skin, subcutaneous tissue, etc. can convert the energy of ultrasonic waves into heat energy, dilate blood vessels in these parts, expand the caliber of skin pores, sweat gland ducts, etc., thereby enhancing the ability to absorb drugs. Ultrasonic waves oscillating at high frequencies change the structure of the skin layer during transmission, and disorder the lipid bilayer of the stratum corneum, increasing its permeability. In addition, the acoustic microfluidic effect of ultrasound can transport the drug to the channels of the skin, sweat glands and hair follicles, and this acoustic microfluidic can also generate shear force to reduce the barrier effect of the skin, so that the drug can diffuse more easily. At the same time, the medium and intracellular gas molecules, the vibration of the bubbles and the rupture of the bubbles caused by the action of the ultrasonic wave form a void or cavity, which is called the cavitation effect, and some channels are formed inside the tissue, which greatly promotes the transdermal absorption of the drug.

Intermediate frequency electricity is a stimulating current with a pulse frequency of 1-100kHz. When the medium-frequency electricity acts on the treatment site, it will cause the movement of electrons and ions in the human tissue, mainly produce a physical and chemical reaction of polarization or depolarization at the nerve endings, and then cause a local physiological effect of sensory nerve conduction disorder, which has the functions of analgesia and dredging of the meridians. , Promote blood circulation, improve nutrient supply, stimulate damaged tissue regeneration, and enhance the immune function of the body.

The thermal effect of ultrasound and medium-frequency electricity will promote the transdermal absorption of drugs during the treatment of ultrasonic conductivity meters, and will also cause the temperature of the ultrasonic electrode probe and skin tissue to rise, resulting in discomfort or even burns for patients. At present, many ultrasonic conductivity meters have been developed and applied in clinical treatment, but none of them have made corresponding improvement measures for the temperature change of the ultrasonic electrode probe, which has affected the treatment experience and even the treatment effect of patients. The temperature control device involved in the utility model makes up for this deficiency, and avoids the stimulation and injury to the patient caused by the heat effect of the ultrasonic wave and the intermediate frequency electricity.

Contents of the invention

The purpose of this utility model is to make up for the deficiencies in the prior art, and provide an ultrasonic conductivity meter with a temperature control device, which can effectively avoid stimulation and injury to patients due to the heat effect of ultrasonic waves and intermediate frequency electricity, and improve the treatment experience of patients.

In order to achieve the above object, the utility model adopts the following technical solutions:

The ultrasonic conductivity meter includes an ultrasonic electrode probe, an acquisition board, an industrial computer and a touch screen, the ultrasonic electrode probe, the acquisition board, the industrial computer and the touch screen are connected in sequence, and the ultrasonic electrode probe and the acquisition board include a temperature control device. A temperature sensor is arranged on the electrode circuit board in the ultrasonic electrode probe, and a temperature acquisition module and a temperature control system are arranged on the acquisition board. The temperature sensor, the temperature acquisition module and the temperature control system constitute a temperature control device. The temperature sensor senses the temperature within the ultrasound electrode probe. The temperature acquisition module receives the temperature information of the temperature sensor and transmits it to the touch screen and the temperature control system. The temperature control system controls the ultrasonic conductivity meter to adjust the output intensity of ultrasonic and intermediate frequency electricity. During the treatment process, when the temperature of the ultrasonic electrode probe and skin tissue rises to cause discomfort to the patient or the temperature information received by the temperature sensor reaches the threshold set by the temperature control system, the output intensity of the ultrasonic wave and intermediate frequency can be adjusted. Thereby adjusting the temperature of the ultrasonic electrode probe and skin tissue.
