  • Publication number: 20220257123
    Abstract: Provided is a small blood viscosity measurement kit and a cartridge therefor. The small blood viscosity measurement kit configured to measure a blood viscosity includes: a kit body; two blood pipes disposed symmetrically on two sides of the kit body, wherein an upper side of each of the two blood pipes is open and configured to receive blood injected thereinto; and a fine channel connected to a lower side of the each of the two blood pipes. When blood is injected into one of the two blood pipes, the blood is supplied to the other of the two blood pipes through the fine channel. In addition, there is provided a small blood viscosity measurement kit cartridge, in which a plurality of small blood viscosity measurement kits are stored and kept, and the small blood viscosity measurement kit cartridge automatically supplies the small blood viscosity measurement kits.

  • Patent number: 6662823
    Abstract: Quantity of fluid can be more precisely controlled without disassembling the valve by an automatic flow control valve, which can be quietly operated and repaired and maintained in simple and easy manner. In the control valve, a valve body has a fluid channel and a chamber, which are formed in the valve body and communicate with each other. A diaphragm is disposed in the chamber and has a fluid channel switching shaft connected to one surface thereof. A flow control member is assembled with the valve body and extends toward the fluid channel. A fluid transfer hole communicating with an entrance port is formed at an upper portion of a side surface of the chamber, so that an opening degree of the fluid channel can be automatically controlled by the fluid channel switching shaft connected with the diaphragm when the diaphragm is operated by pressure of the fluid transferred through the fluid transfer hole.
