Automatic superficial venipuncture and catheterization equipment

Abstract

The invention belongs to the field of medical equipment, and particularly relates to intelligent equipment for improving the one-time success of superficial venipuncture and catheterization, and a usemethod thereof. In order to solve the problem of a low one-time success rate of superficial venipuncture and catheterization, the invention focuses on solving two core problems of venous displacementand a limited safety range of a puncture diameter line when venipuncture and catheterization are carried out. A near-infrared illumination imaging vein positioning assembly is used to analyze, automatically identify and select a puncture vein; a vein fixing and puncture assembly is designed to realize vein fixing and innovate a safe puncture and catheterization method; a blood return recognitionassembly is used to realize the monitoring feedback of superficial venipuncture and catheterization, and judge whether the puncture is successful or not; a disinfection film-sticking assembly is usedto realize skin disinfection before puncture and indwelling needle film-sticking fixing after puncture; and a support fixing assembly designed according to anatomy is used to complete comfortable support fixing of a limb where a venipuncture site is located. The beneficial effects are that the certainty of the success of superficial venipuncture is greatly improved, the pain of patients is reduced, and the medical safety is improved.

Description

technical field [0001] The invention belongs to the field of intelligent medical devices, and in particular relates to an operation method and equipment for improving the one-time success rate of superficial venipuncture and tube placement. Background technique [0002] Superficial venipuncture is a key operation for clinical venous blood collection, intravenous drug administration, and fluid replacement. At present, it is basically done manually by medical staff, and the success rate of one-time puncture varies. As a result, medical efficiency is reduced, patients' pain is increased, and in severe cases, it even affects the harmonious relationship between doctors and patients. Although vein imaging equipment can be used to improve the visibility of veins and improve the success rate of venipuncture to a certain extent, the uncertainty of manual puncture is still unavoidable. The existing patents for automatic venous blood collection equipment improve the success rate of ve...

AI Technical Summary

Problems solved by technology

This kind of equipment is prone to puncture failure when venipuncture is performed for patients with insufficient intravascular pressure such as shock, so it is impossible to ensure a successful puncture

And this type of equipment is currently only designed to solve venipuncture blood collection, does not have the function of venous catheterization, and cannot meet the needs of clinical infusion therapy
