Description

technical field [0001] The present invention relates to lancets. More specifically, the present invention relates to a lancet for collecting body fluids such as blood. Background technique [0002] In order to measure the blood sugar level of a diabetic patient, it is necessary to collect the patient's blood. Only a small amount of blood can be collected. Therefore, a lancet capable of collecting a small amount of blood is used to measure the blood sugar level. Such a lancet is provided with a puncture needle for puncturing a predetermined part of the body (for example, Patent Document 1). [0003] Typically, a lancet is used with a syringe. Such a syringe has a function of firing the lancet toward a predetermined site. When in use, after loading the lancet into the syringe, the lancet is fired with the plunger in the syringe, thereby puncturing a predetermined site. [0004] Patent Document 1: US Patent Specification No. 5385571 [0005] So far, the applicant has com...

Problems solved by technology

In such a case, if the shape and size of the lancet do not match the cylindrical part to some extent, the lancet cannot be reliably fixed.

That is, if the shape and size of the cylindrical portion of the push rod are incorrect, the lancet cannot be properly connected to the push rod, or even if they can be connected, it is difficult to remove the lancet after puncturing.
