Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a puncture having a specific shape so that a puncture site of a medical needle into skin can be specified by tactile sensation without relying on visual acuity, and the puncture site can be easily recognized. Related to a part recognition tool.

[0002]

2. Description of the Related Art Conventionally, in a puncturing operation relating to injection, blood collection, etc., when specifying a contact site of a needle such as an injection needle or a blood collection needle, that is, a puncture site, the area is considerably wider than the size of the puncture site. Is generally disinfected with isodine (manufactured by Meiji Seika), oxidol, or the like, and puncture is made at a point in the approximate center of the disinfected wide area.

[0003] In addition, in self-injection of insulin in diabetic patients, many patients have reduced visual acuity, and it is sometimes difficult for these patients to visually identify the puncture site by the above-described method. It was necessary to rely on the feeling of wetness and coolness of the disinfectant applied to the skin.

[0004] Further, in the self-measurement of blood glucose level of a diabetic patient having a reduced visual acuity, first, in order to specify a puncture site,
Disinfection is performed in the same manner as in the above disinfection method, and the puncture site is specified while relying on the feeling of moistness or coolness of the disinfectant, and then bleeding with a medical needle or the like. Thereafter, a test instrument or test reagent for measuring blood glucose is brought into contact with the bleeding site. In this way,
Perform self-monitoring of blood sugar, but most disinfectants
When there are many volatile chemicals and contact the test reagent,
In many cases, the sensation of moistness or cold is already paralyzed, and in order to recognize the bleeding site, it is necessary to rely on the painful sensation at the bleeding site. The bleeding was only a few millimeters in diameter and was difficult to identify for patients with reduced vision.

[0005] On the other hand, when a diabetic patient with reduced visual acuity selects isodine (manufactured by Meiji Seika), which is one of the most widely used disinfectants, the potency of this disinfectant is maximized. It is difficult to identify a puncture site by recognizing a feeling of wetness or coolness after the disinfectant is dried after application to the skin and drying.

[0006]
