Skin test injection mechanism and control method thereof

Abstract

The invention provides a skin test injection mechanism, which comprises a connection frame, an injection frame, an injection arm, a puncture power mechanism, a puncture frame, a clamping device, an injection power mechanism and a pushing plate, wherein, the injection frame is horizontally rotatably arranged on the connection frame; the injection arm is vertically rotatably arranged on the injection frame; the puncture power mechanism is fixedly arranged on the injection arm; the puncture frame is fixedly arranged on the output end of the puncture power mechanism; the clamping device is fixedlyarranged on one axial end, which is far away from the puncture frame, of the puncture power mechanism, and is used for clamping a skin test injection needle; the injection power mechanism is fixedlyarranged on the other axial end of the puncture frame; and the pushing plate is fixedly arranged on the output end of the injection power mechanism, is used for being cooperated with the pushing rod of the skin test injection needle and drives the pushing rod to be pushed for drug administration. The invention also provides a control method for the skin test injection mechanism, and provides a specific operation method for a skin test process. Air in skin test liquid in needle tubing is discharged, an injection quantity of the skin test liquid is accurately controlled, and the safety of a skintest process and measurement result accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of skin tests, and more specifically, the invention relates to a skin test injection mechanism and a control method thereof. Background technique [0002] In medical work, infusion is routinely performed, but when injecting penicillin and other drugs that are likely to cause allergic reactions, skin testing is an essential step, and it is an extremely important step. At present, the skin test operation is basically done manually by medical staff. The success rate of a skin test injection has a lot to do with the experience of the medical staff, which also leads to uneven success rate of a skin test injection. It not only reduces the medical efficiency, but also increases the suffering of patients. In addition, it is inevitable that people will come into contact with each other during the artificial skin test, and there is a higher probability that the outbreak of infectious diseases will be caused by contac...

[0005] However, the above-mentioned method is a micro-volume liquid injection operation or a blood collection operation, and a syringe or a blood collection needle needs to be injected into a blood vessel for subsequent operations, which is essentially the same as a skin test (intradermal or subcutaneous injection, never in a blood vessel). Therefore, the specific operation is also completely different
