An integrated device for abstracting, collecting, transporting and measuring trace tissue fluid is provided with a vacuum Venturi tube generator which is communicated with a positive pressure source through pipe. The vacuum end of Venturi tube generator is respectively communicated with a tissue fluid absorbing chamber, a sample solution collecting chamber and a waste liquid tank through pipes. One end of tissue fluid absorbing chamber is communicated with a phosphate buffer box through a pipe. The outflow end of tissue fluid absorbing chamber is communicated with the sample solution collecting chamber through a pipe. The outflow end of sample solution collecting chamber is communicated with a flowmeter used for measuring the volume of tissue fluid. The flowmeter is communicated with the waste liquid tank through two paths of a pipe and a bidirectional gate valve installed on the pipe, wherein one path is directly communicated with the waste liquid tank, and the other end is communicated with the input end of glucose sensor. The invention realizes all actions which are continuous in one set of device, automatic control and operation. The invention realizes the miniaturization of whole device for abstracting, collecting, transporting and measuring tissue fluid.

The invention relates to a device and method for coupling a catalyst recovery process with a dynamic disc membrane separation process. The device comprises a reaction kettle, a rotary device, a recoil tank, a clear liquid tank, a recoil tank feeding pump and a reaction kettle built-in dynamic disc separator body. The whole system is fully-closed, so that other impurities are prevented from being introduced; the cross-flow filtration operation is carried out by the adopted microfiltration or ultrafiltration dynamic disc, so that the permeation flux of the dynamic disc is high and the equipment investment cost is reduced while the technological process is shortened; the discharging effect is stable and the rejection rate of a superfine catalyst reaches more than 99%; the permeation flux recovery rate of the cleaned dynamic disc can reach more than 90%, the cleaning cycle is long, the integration level of a filter-recoil device structure is high, the continuous operation can be performed, and the economic benefit is also increased to a certain extent while the cost is saved; the dynamic disc is resistant to high temperature, acid, alkali and an organic solvent, and can be applied to various reactions; and the dynamic disc is low in running power consumption, small in occupied area and low in requirement on performance stability of feeding liquid.

The invention provides a dynamic-inertia guiding control device, which includes a cylinder body, a piston and a main spiral tube. The piston divides the inner chamber of the cylinder body into an upper chamber and a lower chamber. Spiral tube; the piston includes a piston body, a mass block and a spiral groove; the piston body is provided with an inner cavity, and the inner cavity communicates with the upper cavity and the lower cavity respectively; the two ends of the mass block are respectively installed by elastic devices In the inner cavity; the inside of the piston body is provided with a number of spiral grooves uniformly distributed along the inner cavity, a part of the spiral grooves communicates with the upper cavity and the inner cavity, and the other part of the spiral grooves communicates with the lower cavity and the inner cavity; The mass block selectively connects or blocks several of the spiral grooves with the inner cavity according to changes in acceleration. The invention realizes the identification and follow-up control of the acceleration directions of the two ends, so that the acceleration-based semi-active control method can be passively realized without relying on the input of external energy, and the device has a high degree of integration and is easy to arrange.

The invention relates to a nuclear magnetic resonance gyroscope sensitivity detection unit and a manufacturing method of the nuclear magnetic resonance gyroscope sensitivity detection unit and belongs to the field of atom sensors. The nuclear magnetic resonance gyroscope sensitivity detection unit aims to solve the problems that an existing sensitivity detection unit is low in accuracy and can not meet the requirements of a nuclear magnetic resonance gyroscope. According to the nuclear magnetic resonance gyroscope sensitivity detection unit and the manufacturing method of the nuclear magnetic resonance gyroscope sensitivity detection unit, the main structure is completed by means of the 3D printing technology, and the positions of all elements are directly limited; lasers emitted by a VCSEL laser device are polarized through a polarizer, collimated through a small-focal-length collimation lens and then emitted into a nuclear magnetic resonance air chamber after the polarization state is adjusted through a 1 / 4 wave plate; alkali metal atoms and inert gas atoms in an atom air chamber are pumped into an excited state through pump light first, and then the emitted light of the nuclear magnetic resonance air chamber is emitted to the photosensitive surface of a photoelectric detector to complete detection of nuclear magnetic resonance signals. The nuclear magnetic resonance gyroscope sensitivity detection unit and the manufacturing method of the nuclear magnetic resonance gyroscope sensitivity detection unit are suitable for development of a micro-structure nuclear magnetic resonance gyroscope system.
