Automated Syringe Assist Device for Massive Lipolytic Agent Injection

Background and ObjectivesThis study aims to improve the inconvenience of injecting a conventional syringe.We propose a pen-type injection-assisting device that can automatically apply pressure to a replaceable cylinder using an electric motor.Generally, injection with a syringe is one of the most important techniques in clinical practice and is particularly used when lipolysis or anesthetic agents are injected.Currently, a general syringe is used for lipolysis injection, and a large amount of drugs are injected, resulting in significant fatigue of the fingers of medical personnel.In addition, it is difficult to inject with a syringe while maintaining a constant pressure due to fatigue. Materials and MethodsThe assisting device is demonstrated as a model for a 3D automatic syringe assist device.The main body is a plastic syringe detacher, and all internal accessories were made of plastic, except for the holder and motor which are in the form of a metal clip. ResultsThe present invention is a device that uses an electric motor and a cogwheel connected thereto to apply positive pressure to a cylinder while holding the syringe with one hand, like a pen, and pressing a presser bar with the push of a button. ConclusionBy improving discomfort during the injection process due to manipulation of both hands, side effects, such as pain and hematoma that patients may experience after surgery can be alleviated.
