Description

Applicator and applicator assembly Technical Field The present invention relates to an applicator and an applicator assembly, and more particularly, to an applicator and an applicator assembly for inserting a transcutaneous sensor for detecting biological information subcutaneously. Background Chronic diseases such as diabetes require constant management. Diabetes is usually asymptomatic in early stages, but with the progression of the disease, characteristic symptoms such as polydipsia, polyphagia, diuresis, weight loss, general fatigue, skin itching, difficult and durable healing of hand and foot wounds, etc. appear. As diabetes progresses further, complications such as vision disorders, hypertension, kidney disease, stroke, periodontal disease, muscle cramps and neuralgia, gangrene, etc. may occur. To diagnose such diabetes and manage to prevent the development of complications, systemic blood glucose monitoring and treatment should be performed simultaneously. A diabetic patient or a person who has not yet had diabetes but whose blood sugar exceeds the standard needs to continuously and periodically measure blood sugar in order to manage diabetes or prevent it from developing into diabetes. Currently, the main method for measuring blood glucose is a blood sampling method, that is, blood is collected from a fingertip or the like and blood glucose is measured once. However, with respect to blood-drawing blood glucose measurement methods, pain accompanying the blood drawing process and discomfort caused thereby and the like make such methods have limitations in continuous and periodic blood glucose monitoring. In recent years, in order to overcome the limitations of blood sampling type blood glucose measuring methods, a blood glucose measuring system has been developed and put into use by inserting a percutaneous sensor subcutaneously and continuously and periodically measuring blood glucose. Blood glucose measurement systems using a transcutaneous sensor are typically arranged to comprise a wearable unit comprising the transcutaneous sensor and being arranged to be attachable to the body, an applicator arranged to be coupled with the wearable unit in advance for inserting the transcutaneous sensor subcutaneously while attaching the wearable unit to the body, and a receiving unit for processing information received from the wearable unit. In addition, for hygiene and prevention of infections and the like, wearable units are often arranged to be worn once and discarded, and applicators are also often arranged to be triggered once and discarded. In other words, if the transcutaneous sensor is not inserted in the correct subcutaneous position, or the wearable unit is not normally attached to the skin, it must be discarded regardless of the respective service lives of the wearable unit and the applicator. Therefore, in order to improve the convenience of use and economy of a blood glucose measurement system using a percutaneous sensor, there is a need for an applicator that is capable of inserting the percutaneous sensor into the correct subcutaneous position while stably attaching the wearable unit to the skin. Disclosure of Invention Technical problem to be solved An aspect of the present invention is to provide an applicator and an applicator assembly that can stably attach a wearable unit to skin while inserting a percutaneous sensor to an accurate subcutaneous location. The object of the present invention is not limited to the above. Other objects of the present invention will be readily apparent to those skilled in the art from the entire contents of the present specification. Solution method The invention is defined by the independent claims. Other aspects of the invention are disclosed in the dependent claims.
