Description
Technical field
The present invention relates to medical instruments field, and in particular to a kind of ultrasound guidance nerve block anesthesia liquid medicine injection system.
Background technology
As ultrasound guidance nerve block anesthesia technology is carried out extensively in clinical anesthesia so that clinical anesthesia is more smart
Standardization, patient's more comfortableization, but there is also some problems simultaneously --- and syringe control is unstable when being administered after puncturing successfully, leads
Cause tip position to change, cause Accessory injury and local anaesthetics local anaesthetics poisoning etc. caused by injection blood vessel by mistake of patients' neural's blood vessel
Problem！
The content of the invention
To solve the above problems, the invention provides a kind of ultrasound guidance nerve block anesthesia liquid medicine injection system, reduce
The generation of complication of anesthesia, reduce pain to patient.Substantially increase the single security for implementing nerve block anesthesia！Save
Manpower.
To achieve the above object, the technical scheme taken of the present invention is：
Ultrasound guidance nerve block anesthesia liquid medicine injection system, including medicine-filling device housing and syringe needle, the medicine-filling device shell
Internal front end is installed with a syringe, and rear end level is installed with a slide rail, and the piston rod of syringe passes through connecting rod
Sliding block is connected with, the sliding block slips with slide rail, and the syringe needle tail end is connected with connecting tube and connecting wire by needle stand, described
Connector for being connected with the connecting wire, the medicine-filling device housing are installed on medicine-filling device housing forward end outer wall
Tail end is embedded to be provided with a controller, and the controller is electrically connected by wire with the sliding block and connector, the syringe needle by
Needle point and three rib type needle tubings are formed, and three ribs of three rib type needle tubings are round blunt rib, and the needle point is by three equilateral triangles
Surround, each equilateral triangle center is provided with a medicine outlet hole.
Preferably, the outer wall of the medicine-filling device housing is provided with the adjusting knob being connected with the controller, for adjusting
Save rate of administration.
Preferably, the connecting tube is used to be connected with the front end of the syringe needle.
Preferably, the central point of the medicine-filling device housing, syringe, sliding block and slide rail is not on same horizontal line.
Preferably, it is provided with chargeable battery in the controller.
The invention has the advantages that：
By simple button switch, pumpback before drug injection and injection is realized, so as to whether judge needle point
In the blood vessels, the neurovascular Accessory injury and medicine that the variation of tip position is brought when avoiding injection and pumpback inject blood by mistake
Local anaesthetics caused by pipe is poisoned, and is greatly reduced the generation of complication of anesthesia, is reduced pain to patient.Substantially increase one
Implement the security of nerve block anesthesia, save manpower！
