TECHNICAL FIELD
[0001] The utility model relates to medical testing device technical field, especially a medicine delivery device detection tool. BACKGROUND
[0002] Insulin injection is a traditional diabetes treatment method, and patients inject a certain dose of insulin into subcutaneous tissue through an injection pen to control blood sugar. The accuracy of the insulin injection dose is crucial for blood sugar control, and insufficient dose will lead to poor blood sugar control, and excessive dose will lead to hypoglycemia, thereby affecting the health and safety of patients. Although the injection pen has a dose adjustment function, patients can adjust the required dose through the knob, but due to the inherent structure, material selection and production process of the injection pen, the adjusted dose of most injection pens is not consistent with the actual injection dose, leading to inaccurate dose. Therefore, it is necessary to detect the dose accuracy of the injection pen.
[0003] When detecting the dose of the injection pen, the injection knob of the injection pen needs to be rotated. A rotating and pressing device for assembling a screw rod is disclosed in Chinese Patent No. CN215035170U, which comprises a machine base, a vertical plate installed on the upper side of the machine base, a servo lifting linear module installed on one side of the upper end of the vertical plate, a servo motor transmission connected to the upper side of the servo lifting linear module, a rotary head transmission connected to the servo lifting linear module on the lower side of the servo motor, an angle origin sensor installed on one end of the servo motor, an assembly table installed on the upper side of one end of the machine base, and a positioning mechanism installed on the upper side of the assembly table. The utility model is provided with a rotary head transmission connected to the servo lifting linear module on the lower side of the servo motor, and an angle origin sensor installed on one end of the servo motor, which is used for accurately assembling the throttle valve screw rod, has the advantages of high assembly position precision, high assembly angle, controllable assembly position and angle, etc.
[0004] In the above-mentioned scheme, the injection knob of the injection pen can be rotated by the rotary head, so as to control the downward movement of the push rod in the dose sleeve of the injection pen, and the single-rotation injection dose of the injection pen can be determined by detecting the displacement of the push rod. However, the rotating and pressing device can only perform a single-rotation pressing action on the injection knob of the injection pen, and the detection of the full dose of the injection pen requires multiple pressing actions on the injection knob. Therefore, the rotating and pressing device cannot complete the automatic detection of the full dose of the injection pen. UTILITY MODEL CONTENTS
