Abstract

The invention discloses a subcutaneous administration device based on low-temperature plasma. The subcutaneous administration device is composed of a plasma administration electrode, a plasma breakdown electrode, a drug cabin and a multi-frequency pulse plasma power supply, wherein the plasma administration electrode is used for breaking through the epidermal layer and the corium layer of the skinto open an injection channel of the skin; the plasma breakdown electrode is used for injecting drugs into the channel opened by the plasma administration electrode; the drug cabin is used for storingthe injected drugs; and the multi-frequency pulse plasma power supply is used for controlling the plasma breakdown electrode to generate different voltages and plasmas in different application scenesso as to control the skin breakdown situation. By means of the subcutaneous administration device based on the low-temperature plasma, the pain of a human body to subcutaneous injection administration can be relieved, and meanwhile effective absorption of the drugs in the human body is improved.

Description

technical field

[0001] The invention relates to the technical field of subcutaneous drug delivery devices, in particular to a low-temperature plasma-based subcutaneous drug delivery device. Background technique

[0002] At present, the drug delivery technology for penetrating the skin surface is based on needle injection, but the needle injection method often causes pain, inflammation or infection damage to the skin because of the large size of the needle. The low-temperature plasma-based subcutaneous drug delivery device reduces the size of the needle and injects it into the skin through tiny electrode pinholes, thereby reducing pain and damage to human skin tissue. In addition, the subcutaneous drug delivery device based on low-temperature plasma can better ensure the pharmacology of the injected drug, and the plasma discharge of the electrode to the skin tissue can improve the activity of the skin tissue, so as to better achieve the effect of drug absorption.
