Abstract

The present invention relates to a disposable cartridge. A housing (70) forms a cartridge (22), and a slider (72) is displaceably provided in the housing (70) with a set of guide rails (78) in between. A hook (80) is tiltably provided between the guide rails (78). After the cartridge (22) is installed in a piercing device (10), the slider (72) is displaced to the other end side of the housing (70) while in contact with a casing (12) forming the piercing device (10). This causes the hook (80) not to be tiltable by the slider (70). An end of the hook (80) comes into contact with a step (26) of the casing (12) to limit the installation of the cartridge (22) in the piercing device (10).

Description

technical field [0001] The present invention relates to a disposable cartridge for piercing the skin of a subject or measuring blood components, and more particularly to a disposable cartridge that cannot be reinstalled in a device after being used. Background technique [0002] In recent years, daily self-management methods of measuring changes in blood sugar levels by themselves have been recommended for diabetic patients. In order for the patient to collect his own blood for the measurement of the blood glucose level, it is common to use a piercing device, which applies a repulsive force from an elastic member to an axially movable piercing needle, so that the piercing needle is ejected instantaneously and A small amount of blood is drawn by puncturing the patient's skin. [0003] For hygienic reasons, the cartridge including the puncture needle is disposable, the cartridge can be detached from the puncture instrument and discarded each time the blood glucose level is me...
