Venipuncture device and system

Abstract

Provided are a venipuncture device (1), system, and venipuncture control method, said system comprising: a control device (2) and a venipuncture device (1); the venipuncture device (1) and an ultrasonic probe (13) are each connected to the control device (2); the venipuncture device (1) is used for capturing data information of a preselected target vessel and sending same to the control device (2); the control device (2) is used for calculating, according to the data information, position information of the target vessel and generating a control signal according to the position information; the venipuncture device (1) is also used for controlling, according to the control signal, a to-be-punctured needle body (5) and to-be-inserted flexible tube, fixed to said device, to puncture skin. The overall manufacture cost of the device and system is lower than that of a robot medical system; the invention is capable of automatically controlling the venipuncture device (1) to perform the movements of needle insertion, tube placement, and needle removal, reducing the intensity of labor of an operator; furthermore, the invention is matched with an ultrasonic probe (13) and, under the guidance of the ultrasonic probe (13), achieves highly accurate positioning; it may be operated using one hand and reduces the experiential requirements of the operator and is adaptable to a dynamic environment.

Description

technical field [0001] The present invention relates to the technical field of automatic catheterization, in particular to a venipuncture device, a system and a venipuncture control method. Background technique [0002] Venipuncture is a medical nursing method to alleviate the patient's pain of repeated puncture and facilitate long-term infusion. Venipuncture can effectively avoid the pain caused by repeated puncture of superficial veins, and it can also effectively avoid the damage of antitumor drugs to blood vessels and local tissue necrosis caused by drug extravasation. The key points affecting the development of venipuncture catheterization technology are the puncture guiding device and the control of the puncture needle movement. Compared with manual operation, the auxiliary medical robot using mechanical force has high accuracy and stability, and can reduce the labor intensity of the operator. Therefore, in order to perform soft tissue puncture surgery stably and acc...

Problems solved by technology

[0003] However, due to factors such as the high cost of robots, the complicated calibration and matching methods of robots and patients, and the overly specialized operation of robots, it is still difficult for robot-assisted puncture to reach the level of widespread application.
