Problems solved by technology

[0003] At present, this operation usually requires the cooperation of two people. After the operator places the needle tip next to the target nerve, the assistant must push the syringe to administer the drug. The speed and resistance of the drug injection depend on the assistant's hand feeling, and the operator cannot feel it directly. There are certain potential safety hazards in controlling the injection pressure and mastering the injection speed
[0004] At present, there is a lack of a device that can realize single-person operation, display and adjust the resistance of drug injection

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a nerve block medicine injection system capable of adjusting injection resistance. The nerve block medicine injection system comprises a workbench, an injection device, a main machine and a pedal device, the injection device and the main machine are installed on the workbench; the injection device comprises a hollow fixing box, a positioning assembly for fixing an injector and a driving assembly for pushing injection, and the positioning assembly comprises a pressure sensor for monitoring injection resistance; the main machine is used for receiving and displaying injection pressure information; and the pedal device is connected with the driving assembly and used for controlling the injection mode and speed. The defects in the prior art are overcome, the resistance in the injection process is displayed in real time, a single person is helped to operate, and the safety of nerve block medicine injection is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a nerve block drug injection system capable of adjusting injection resistance. Background technique [0002] In recent years, ultrasound-guided nerve block anesthesia has been widely used in surgical operations. Ultrasound-guided nerve block requires the operator to place the probe on the patient's skin surface with one hand, scan the cut surface where the target nerve is located, fix the probe, and hold the needle with the other hand to advance the needle tip to the target nerve under the guidance of ultrasound, and inject local anesthetic solution to wrap The nerve achieves a block effect such as local analgesia. [0003] At present, this operation usually requires the cooperation of two people. After the operator places the needle tip next to the target nerve, the assistant must push the syringe to administer the drug. The speed and resistance of the drug ...
