Problems solved by technology

[0003] Interventional puncture therapy for cardiovascular diseases is a relatively common treatment method. In actual situations, it is necessary to puncture the relevant parts through injection needles to draw blood or fluid for testing. The current operation is to use ordinary syringes for operation. When drawing blood, it is necessary to manually pull out the piston rod. One hand is required to fix the syringe and the other hand is to operate the piston rod. safety hazard

Abstract

The invention provides a puncture and intervention dual-effect assisting injection and suction method, and belongs to the technical field of medical instruments and apparatuses. The method structurally involves an injector and further involves a speed adjustment advancing and retreating mechanism. A miniature forward and backward rotation low-speed motor conducts outputting to drive a driving gear. The driving gear is meshed with a driven gear constantly. The miniature forward and backward rotation low-speed motor rotates forward and backward to drive an inclined rotating shaft to rotate forward and backward. The inclined rotating shaft rotates forward and backward for outputting to drive a slider to rotate forward and backward. The slider rotates forward and backward opposite to the forward and backward rotation of a rotary rolling conical roller body for outputting to drive a through shaft to rotate forward and backward. The through shaft rotates forward and backward together with the forward and backward rotation of a threaded section through shaft to drive a nut to horizontally slide forward and backward along a linear rail key. The nut horizontally slides forward and backwardto drive a piston rod to move forward and backward. The piston rod acts on an injector cylinder body, so the injection action or suction action is realized; full-automatic suction is realized, safetyis high, intermittent controllable injection or suction can be realized, and the design is ingenious.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a method for puncture-intervention double-action assisted injection and suction. Background technique [0002] Generally, puncture is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for laboratory tests, gas or contrast agent is injected into the body cavity for contrast examination, or drugs are injected into the body cavity. The purpose is to draw blood tests, blood transfusion, infusion and catheterization for angiography. [0003] Interventional puncture therapy for cardiovascular diseases is a relatively common treatment method. In actual situations, it is necessary to puncture the relevant parts through injection needles to draw blood or fluid for testing. The current operation is to use ordinary syringes for operation. When drawing blood, it is necessary to manually pull out the piston rod. On...
