  • Patent number: 11452843
    Abstract: An injection device is described including a detection unit that includes an electrode that detects electrical characteristics of a biological tissue, a follow-up mechanism that follows motions of the biological tissue, and a puncture unit capable of puncturing the biological tissue. The injection device is configured to administer a predetermined substance to the biological tissue through a hollow portion defined in the puncture unit. A position of the puncture unit is specified based on a position of the electrode. The follow-up mechanism includes a spiral portion spirally extending around the puncture unit, and being stretchable and compressible along an extending direction of the puncture unit. Electrodes are disposed on an annular distal-end projected plane of the spiral portion, as seen from a distal end side of the puncture unit, along a circumferential direction of the puncture unit.

  • Publication number: 20220251986
    Abstract: A blow-by gas recirculation device that, while having a structure in which a passage for blow-by gas is in a head cover and an oil separator, an increase in size of an engine is suppressed and the risk of the freezing is mostly avoided by shortening the length of an external pipe for the blow-by gas. Therefore, the blow-by gas recirculation device guides blow-by gas from a crankcase to an intake passage through an in-cover gas passage formed inside a head cover. An oil separator that traps and removes oil from the blow-by gas is attached to the inside of the head cover. A pressure regulating valve is provided on the outlet side of the in-cover gas passage in the head cover. A separator outlet, which is an outlet for the blow-by gas in the oil separator, is overlapped on a blow-by gas inlet portion of the pressure regulating valve.

  • Publication number: 20210259673
    Abstract: A drug supply device for supplying drug to a living body surface that includes a shaft and a drug holding sheet attached to the distal end of the shaft. The drug holding sheet has a first face that faces distally and a second face opposite the first face that faces proximally when the drug holding sheet is expanded. The drug holding sheet includes folded portions that fold such that the first face is positioned to face radially inward while exposing the second face to an outside environment when the drug holding sheet is in a folded state. A drug is applied on the first face of the drug holding sheet. The drug supply device includes an expandable member on the second face of the drug holding sheet. The expandable member is expandable to cause the drug holding sheet to expand from the folded state into the expanded state.
