Abstract

The invention relates to an ultrasonic medicine leading therapeutic apparatus, which belongs to medical medicine leading therapeutic apparatus and performs non-invasive and painless leading of medicines. The invention discloses a novel administration method. A low-frequency ultrasonic generator of the ultrasonic medicine leading therapeutic apparatus is controlled by a program controller and a time controller of a microcomputer chip to generate a low-frequency ultrasonic electric signal; the signal is led off to an ultrasonic transducer to generate low-frequency ultrasonic waves; and the low-frequency ultrasonic waves are actuated on the skin through a medicine support, generate an ultrasonic 'cavity bubble' microchannel, and simultaneously drive medicines to enter into the subcutaneous part through the microchannel. Various parameters of the low-frequency ultrasonic generator such as frequency, amplitude, phase, power and interval time scale are precisely controlled by a computer program and can be set throguh a keyboard of an input controller; related parameters are displayed by a liquid crystal display; the therapeutic process also comprises the digital display prompt process; and the whole apparatus is supplied with power by a power supply which can be switched on and off by a battery, a charging battery or alternating current.

Description

Therapeutic equipment for introducing medicine

Technical field

The present invention is that medical ultrasonic imports the Drug therapy instrument.Belong to the bonded medical technical field of ultrasonic applications technology and micro computer programmed technology.

Background technology

The sick Drug therapy that needs of people enters in the body medicine by oral, injection often.Can make gastrointestinal system be subjected to medicine irritation damage stomach (intestinal) mucosa to influence normal appetite and alimentation owing to take medicine for a long time, even reduce curative effect of medication; And muscle or the blood diffusion medicinal liquid of injection under skin, rapid-action, good effect, but because the pain of having an injection, particularly need patient and child long-term even needs injection throughout one's life just beyond affordability, for example many diabeticss just need insulin injection every day, therefore get off year in year out, skin is subjected to great injury, the misery brought to patient of injection and oral drugs and be not conspicuous.

It is exactly a kind of injection, oral and have injectable drug effect and oral drugs new technique easily simultaneously that do not need that ultrasonic medicinal imports.This new technique utilizes low-frequency ultrasonic waves to make keratodermatitis produce " cavity " passage exactly, thereby allow drug molecule enter the subcutaneous purpose that reaches Drug therapy by this passage, people-oriented for the new technique that this ultrasonic medicinal imports, painless, noinvasive, have no side effect, opened up the new way of an administration.The present invention's " therapeutic equipment for introducing medicine " is exactly the medicine noinvasive guiding therapeutic apparatus device of new generation according to this principle development.

Summary of the invention

Therapeutic equipment for introducing medicine is made up of micro computer programmed low frequency ultrasound wave producer, frequency variation signal controller, cyclelog, liquid crystal display, ultrasonic transducer and power supply.

Fig. 1 is the structural representation of therapeutic equipment for introducing medicine.

The low frequency ultrasound wave producer [3] of therapeutic equipment for introducing medicine is under the control of microcomputer chip cyclelog [1] and time controller [2], produce the low-frequency ultrasonic waves signal of telecommunication, this signal leads to ultrasonic transducer [7] back and produces low-frequency ultrasonic waves, low-frequency ultrasonic waves sees through drug stent [8] and acts on skin, produce ultrasonic " cavity " microchannel, the while ultrasound wave also promotes medicine and enters subcutaneous through this microchannel.

The frequency of low frequency ultrasound wave producer [3], amplitude, phase place, power, blanking time, parameters such as ratio was by the accurate control of computer program, and can be by the keyboard setting of input controller [5], there is related parameter to show by liquid crystal display [4], therapeutic process also statistics have shown the prompting process, whole instrument is by power supply [6] power supply, and power supply can be used battery, rechargeable battery or use the alternating current Switching Power Supply.

The specific embodiment

Be a specific embodiment of the present invention below:

Present embodiment (Fig. 2) is to be used for insulin fluid by low-frequency ultrasonic waves effect skin, make keratodermatitis produce " cavity " microchannel, it is subcutaneous that thereby the promotion insulin enters along this " passage ", to reach the therapeutical effect of the blood glucose that reduces the diabetes patient.

The insulin medicinal liquid, is contained in [7] on the ultrasonic transducer [6] with being with graduated microsyringe to be added on the drug stent (being insulin medicinal liquid placement section) [7] by iu in the present embodiment, and instrument makes [7] closely contact with skin with band.Press on and off switch [3], time figure on the liquid crystal display [2] promptly begins countdown, the startup work under the control of cyclelog of the low frequency ultrasound wave oscillator of low-frequency ultrasonic waves generation processing system [1], the output ultrasonic wave signal of telecommunication is output as mechanical energy by ultrasonic transducer [6] conversion, the intensity of output ultrasonic wave can be provided with button [4] control by intensity, electronic components such as central controller and relevant IC chip are contained on the wiring board of the two-sided printing of a slice, the complete machine working power is rechargeable battery [5], low-frequency ultrasonic waves signal follow procedure controller and time controller control, the setting timing finishes, and instrument shuts down automatically.

During with external ultrasonic transducer [8], this transducer can be fixed on upper arm or human abdomen with elastic cord, change the people be subjected to be subjected to the drug effect rate with raising in the medicine position.Former airborne ultrasonic transducer [6] quits work during external transducer [8] work.
