Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] It should be noted that when a component is said to be “fixed” to another component, it may be directly on the other component or there may be another intermediate component through which it is fixed. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be another intermediate component at the same time. When a component is said to be "set on" another component, it may be set d...

The invention discloses an automatic injection system, and belongs to the field of medical instruments, a driving part drives an injector to inject and withdraw, a nerve stimulation device comprises a nerve stimulation instrument and a nerve stimulation needle, the nerve stimulation needle is installed on the injector and electrically connected with the nerve stimulation instrument, and the nerve stimulation needle discharges to generate muscle jump during withdraw. The main control box comprises a controller, the controller is in communication connection with the driving part and the nerve stimulator, the controller obtains the injection volume, the injection speed and the pumpback torque of the injection pump and obtains muscle jump information through the nerve stimulator, and the controller judges the medicine absorption condition and the medicine remaining condition according to the obtained information so as to control subsequent injection. Through the design, the injection system can automatically inject, electrically stimulate nerves, withdraw, judge the anesthetic effect and the anesthetic absorption process and determine the subsequent injection amount and injection speed according to the judged anesthetic effect and anesthetic absorption process, and the whole process is automatic and intelligent and high in injection efficiency.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to an automatic injection system. Background technique [0002] In the existing anesthesia injection process, it is necessary to check the anesthesia effect and the absorption process of the anesthetic by electrically stimulating the nerve and withdrawing the syringe. [0003] The withdrawal inspection process is divided into three different situations, specifically: the liquid is not absorbed, and the liquid can be withdrawn. The fluid has been absorbed and withdrawn as a small amount of blood and interstitial fluid. The fluid has been absorbed, and the back pump has almost no fluid close to the cavity. [0004] Existing anesthesia injections require medical staff to manually stimulate the nerves and manually determine which of the above three situations the withdrawal belongs to, and determine the follow-up injection volume and injection speed according to the anesthesia effect an...
