  • Patent number: 11083467
    Abstract: A hemostatic device includes a band for wrapping around a puncture site of a wrist, a mechanism for securing the band to the wrist in a wrapped state, an inflatable portion connected to the band and inflated by being injected with air, a tube body that communicates between an inflatable space of the inflatable portion and an outside, and a cover portion that covers the tube body in the inflatable portion, in which the tube body has a hole portion that opens in the inflatable portion, the cover portion has a communication portion that is disposed to cover the hole portion and allows communication between the hole portion and the inflatable portion by being positioned to overlap the hole portion, and the tube body is movable relative to the cover portion so that a positional relation between the communication portion and the hole portion is controllable.

  • Publication number: 20210180623
    Abstract: A work vehicle includes: a hydraulic pump driven by an engine; a hydraulic actuator that is driven by hydraulic oil supplied from the hydraulic pump; a switching valve configured to switch from one to the other of a first state in which the hydraulic oil supplied from the hydraulic pump is supplied to a first channel and a second state in which the hydraulic oil supplied from the hydraulic pump is supplied to a second channel; a restriction operation device configured to generate an operation signal that restricts the drive of the hydraulic actuator; and a controller that controls the switching valve. The controller includes: an operation signal acquisition unit configured to acquire the operation signal; and an instruction output unit configured to output, to the switching valve, a control instruction that restricts the drive of the hydraulic actuator with the engine driving, in response to the operation signal.

  • Patent number: 10980546
    Abstract: A hemostatic device including a band that is wrapped around a limb of a living body at a site of the living body where bleeding is to be stopped and an inflatable portion which is inflated by injection of gas to cause the inflatable portion to press the site where bleeding is to be stopped. The hemostatic device includes an injection part that injects gas into the interior of the inflatable portion. The injection part includes a hole penetrating the injection part and communicating the housing space with outside environment. The hemostatic device includes a first support plate and a second support plate positioned adjacent one another along the longitudinal direction of the band. The second support plate is movably connected to the first support plate. The inflatable portion is on the first support plate and the injection part is on the second support plate.

  • Patent number: 10939919
    Abstract: A hemostatic device has a band for being wrapped around a puncture site P of a wrist W, securing means for securing the band in a state where the band is wrapped around the wrist, an inflation portion that interlocks with the band, and that is inflated by injecting gas, and an injection portion that can inject gas into the inflation portion. The injection portion is disposed in the band, and is foldable so as to decrease a space formed inside the injection portion. The hemostatic device can thus inflate an inflation portion without using a separate dedicated instrument, which can prevent a hemostasis-requiring site from being unintentionally compressed more than necessary.
