Embodiment Construction

[0035] The inventors of the present application have conducted in-depth studies with a sleeve insert having a simple structure, and the result is a sleeve inserter of an embodiment of the present invention.

[0036] From the viewpoint of providing a sleeve inserter having a simple construction, the present invention is based on "using two coil springs that can be extended by two coil springs extending in opposite directions (forward direction / backward direction) of each other. The movable body, to control the movement of casing and needles ". That is, the present invention is based on "for controlling the action of controlling the movement of the sleeve and needle to control the operation of two coil springs extending in opposite directions in opposite directions."

[0037] Further, the "sleeve inserter" described in the present specification is an apparatus for inserting a sleeve for, for example, the skin surface of the patient, or the like. The "sleeve" described in this spec...

Abstract

Provided is a cannula inserter which includes, inside a casing, a cannula, a needle that is movable inside the cannula, a first movable body, a second movable body, and a biasing mechanism that has a first coil spring and a second coil spring. The first movable body and the second movable body are integrally movable along a direction of advance of the needle by the compressed state of the first coil spring being released and the first movable body being biased by the first coil spring. After the first movable body and the second movable body are moved along the direction of advance to a predetermined location, the first movable body and the second movable body are no longer integral and the compressed state of the second coil spring can be released, so that the second movable body is movable along a direction of retreat of the needle by the second movable body being biased by the second coil spring for which the compressed state has been released.

Description

Technical field [0001] The present invention relates to a sleeve inserter. Specifically, the present invention relates to a sleeve insert for fluid such as a patient to a patient. Background technique [0002] In recent years, it can be said that the number of diabetes patients in the world will continue to increase further. Specifically, it can be said that the number of diabetic patients in the world has about 400 million people, and it will increase to about 700 million. In order to treat diabetes, it is necessary to maintain a constant level of blood sugar, so insulin is essential. [0003] As the insulin administration method, for example, a method of combining insulin pumps and casing inserters, etc. According to this method, an insulin pump can be used and a small amount of insulin is periodically administered through the sleeve insert. [0004] Patent Document 1: Japan Special Open 2014-508607 [0005] Here, the inventors of the present invention recognize that the soil i...
