Medical injection control method and device

Abstract

The invention discloses a medical injection control method and a device. The method comprises the steps: controlling a needle of an injector to be inserted into a body of a patient, and detecting thedepth of the needle inserted into the body of the patient in real time; if the depth is within a preset range of the designated position, controlling a needle cylinder of the injector to press liquidmedicine into the needle head, and detecting the pressure intensity value of the liquid medicine injected out of the needle head into the body of the patient in real time; and if the pressure intensity is within a set range, generating a needle pulling force value after the liquid medicine in the needle cylinder is injected by a set amount, and controlling a manipulator to pull out the needle headaccording to the force corresponding to the needle pulling force value. In the process of the needle head being inserted into the body of a patient, the pressure value applied to the patient by the needle head can be detected in real time through a first sensor, the pressure value applied to the patient by the needle head can be prompted and adjusted in real time, the injection accuracy and the injection effect are improved while the nerve compression of the patient by the needle head is adjusted to reduce pain, the user experience is good, meanwhile, the treatment effectiveness is improved,and the effect is good.

Description

technical field [0001] The present invention relates to the field of medical technology, in particular to a medical injection control method and device. Background technique [0002] In the course of treatment, in the process of injecting liquid medicine to the patient, it is necessary to insert the needle of the syringe into the patient's body, and then inject the liquid medicine into the patient's body. Often when patients are injected with liquid medicine, due to the uneven or excessive pressure of the needle insertion, which exceeds the strength of the patient's nerve compression, or because the needle is inserted directly to the depth of the injection, the patient feels pain and discomfort, such as Children cry because of the pain when they are vaccinated, and even many adults feel pain and discomfort because they cannot bear the pressure exerted on them by the needle. Although this pain is short-lived, many people are afraid of receiving medical treatment related to s...

Problems solved by technology

Often when patients are injected with liquid medicine, due to the uneven or excessive pressure of the needle insertion, which exceeds the strength of the patient's nerve compression, or because the needle is inserted directly to the depth of the injection, the patient feels pain and discomfort, such as Children will cry because of the pain when they are vaccinated, and even many adults will feel pain because they cannot bear the pressure exerted by the needle

Although this pain is short-lived, many people are afraid of receiving medical treatment related to syringe injection because of the pain of injection, which has a very adverse effect on the treatment of patients
