Automatic puncture administration syringe

Abstract

The invention discloses an automatic puncture administration syringe. The automatic puncture administration syringe comprises a needle cylinder part, wherein a second connecting pipe is fixedly installed at one end of the needle cylinder part; a suction part for automatically sucking the needle cylinder part is fixedly installed at the end, away from the needle cylinder part, of the second connecting pipe; a third connecting pipe is fixedly installed at the end, away from the second connecting pipe, of the needle cylinder part; a needle is connected to the end, away from the needle cylinder part, of the third connecting pipe; the suction part comprises a three-way pipe; first connecting pipes are fixedly installed at the two ends of the three-way pipe respectively; a first limiting part is inserted into each first connecting pipe; a box is installed at the ends, away from the three-way pipe, of the two first connecting pipes; and a variable-frequency diaphragm pump is fixedly installed on one side in the box. According to the automatic puncture administration syringe, the dosage, pressure, frequency, mode and medicine temperature of administration or suction can be accurately operated, and the medicine injection accuracy is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an automatic puncture drug delivery syringe. Background technique [0002] When performing inspection and treatment, puncture administration or suction technology is often used, and what is usually used is a disposable syringe for direct administration or suction. However, the existing puncture administration syringe has a single administration mode, and the administration amount, Dosing pressure, dosing frequency and suction pressure, frequency, and drug temperature are all artificially controlled, and the accuracy is not high, which leads to the problem of inaccurate dosage. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides an automatic puncture drug delivery syringe, which solves the problem of the single drug delivery mode of the existing puncture drug delivery syringes, an...
