Problems solved by technology

The needle tube of the syringe is usually reused because it does not touch human blood, and the needle needs to be replaced after each injection. However, when the needle is replaced, the direction of the needle cannot be guaranteed, which often leads to the wrong direction of the needle tip of the needle, making it difficult to insert human body

Embodiment Construction

[0035] specific implementation plan

[0036] In order to realize the above-mentioned technology, the device of the present invention includes a first high-precision camera 1 and a second high-precision camera 3, a servo rotation device 2, an injection needle 4 on an automatic injection instrument, and a light-shielding panel 5, and simultaneously analyzes the high-precision camera The captured image information is equipped with a computer equipped with an image detection algorithm, a servo rotation control device that controls a servo rotation device based on image processing information, and an automatic injection device.

[0037] Firstly, establish a space Cartesian coordinate system for the entire detection device, such as figure 2 A space Cartesian coordinate system is established with the center axis of the needle tube of the injection needle installed on the servo rotating device as the Z-axis, and the cross section at the beginning of the needle tip slope of the needle...

Abstract

The invention provides a position detecting and correcting method and device for an automatic injection instrument syringe needle. A needle tip positioning problem for an injection syringe needle of an automatic injection instrument can be solved; that processes such as transfusion, puncturing, sampling and the like can be performed rapidly and accurately with minimum friction force via the automatic injection instrument each time the syringe needle is changed can be ensured.

Description

technical field [0001] The invention uses the image processing technology to invent a method and device for detecting and correcting the position of the needle tip of an automatic injection device. Background technique [0002] At present, in our country, the clinical infusion, puncture, sampling and other processes using syringes are all done manually by doctors or nurses, which is inefficient. There is an urgent need for automatic injection devices to replace manual work to improve efficiency and relieve the pressure on doctors and nurses. The needle tube of the syringe is usually reused because it does not touch human blood, and the needle needs to be replaced after each injection. However, when the needle is replaced, the direction of the needle cannot be guaranteed, which often leads to the wrong direction of the needle tip of the needle, making it difficult to insert human body. [0003] Specifically, the syringe needle has an anti-biological form, and the needle tip...
