Embodiment 1

[0019] see figure 1 , the drug automatic injection introduction system with electrical stimulation function, including a hand-held housing, an injection device installed in the hand-held housing, a micro-volume automatic injection device connected to the injection device, and a micro-volume automatic injection device electrically connected A drug automatic injection introduction system composed of a console is characterized in that an electric stimulation device is also provided in the hand-held housing, and the electric stimulation device is also electrically connected to the console; the console is provided with a multi-interface The single-chip microcomputer integrates the automatic injection control of the drug and the electrical stimulation through the single-chip microcomputer, and realizes that after the automatic injection of the drug, a signal is sent to trigger the electrical stimulation device, and the electrical pulse signal is generated and transmitted to the recip...

Embodiment 2

[0021] see figure 1 and figure 2 , this embodiment is basically the same as Embodiment 1, and the special features are as follows: the structure of the hand-held housing (500) is: the rear end of a front tube (501) is connected with a rear seat (502) through a threaded structure (505) connection, the front end of the front cylinder (501) slides an end cover (503), and the inner cavity of the end cover (503) is equipped with a spring (504), and the end cover (503) and the sliding sleeve of the front cylinder (501) slide There are steps (506) on the road to limit the sliding of the slide cover (503). The structure of the automatic injection device (400) is: a syringe barrel (401) is fixedly installed in the front barrel (501), and a needle (403) fixed at the front end of the syringe barrel (401) is at the end Inside the cap (503), a syringe piston rod (402) protrudes from the rear end of the syringe barrel (401). The structure of the micro-volume automatic injection device (...

Embodiment 3

[0023] See attached figure 1 , the drug automatic injection introduction system with electrical stimulation function is mainly composed of a micro-volume automatic injection device 100 , an electrical stimulation device 200 , a console 300 , an injection device 400 , and a hand-held housing 500 . The automatic injection device 100 , the electrical stimulation device 200 , and the injection device 400 are packaged in a hand-held housing 500 . The housing 500 is divided into a front cylinder 501, a rear seat 502 and an end cover 503. The front cylinder 501 is connected with the thread structure 505 and 502, and the separation and connection of the front cylinder 501 and the rear seat 502 are realized by rotation. A stepping motor 101 is fixed in the back seat 502 and is connected with a screw mandrel 103 through a bevel gear 102. A slider 104 is connected to the screw mandrel 103 to push the syringe piston rod 402 to realize automatic injection. A pressure sensor 106 is provide...

Abstract

The invention relates to a medicament automatic injection lead-in system with an electronic stimulating function, which comprises a handheld shell, an injector, an automatic microinjector and a control consol, wherein the injector is arranged in the handheld shell; the automatic microinjector is connected with the injector; and the control console is electrically connected with the automatic microinjector. The medicament automatic injection lead-in system is characterized in that: an electric stimulator is arranged in the handheld shell and electrically connected with the control consol; and a singlechip with multiple interfaces is arranged in the control consol. The automatic medicament injection control and electric stimulus are combined by the singlechip, a signal is sent to trigger the electronic stimulator after the medicament is automatically injected, and the generated electric pulse signal is transmitted to a receptor tissue, so the permeability of the cell membranes of the tissue and the medicament absorption ratio of cells are improved.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to an automatic drug introduction system with electric stimulation function. Background technique [0002] For a long time, there are many ways to prevent and treat diseases, such as oral medicine, intravenous injection, intramuscular injection and so on. Once the method is selected, the absorption and efficacy of the drug by the receptor largely depend on the physical and chemical factors of the receptor itself. Research in recent years has shown that in vivo electroporation technology uses electrical pulse signals to change the permeability of cell membranes, which facilitates the entry of drugs into cell tissues and greatly improves the absorption rate of drugs by receptors. This technology has been widely used in the medical field. There have been many drug introduction instruments based on this technology on the market. Such instruments use electrical signals to stimulate...
