Abstract: A urodynamic monitoring system and a drainage monitoring control unit are provided. The urodynamic monitoring system includes a drainage monitoring control unit and a monitoring host that is provided with a mainboard, a control component, and a weighing component, where the drainage monitoring control unit is formed by sequentially connecting a front drainage pipeline, a monitoring controller, a rear drainage pipeline, a urine collection bag, and the front drainage pipeline is provided with a first three-way valve communicated with air. When using this system, the first three-way valve communicated with air may be disposed on the front drainage pipeline, air pressure on a bladder is measured by switching a working state of the first three-way valve, and an accurate value of intravesical pressure is obtained by subtracting the air pressure on the bladder from pressure of urine in a monitoring control cavity.

Abstract: A lighting device (100) and a projection device, comprising a light source for generating a blue excitation light (110), a base board (130), and a wavelength conversion material layer (140) covered on the base board (130). The wavelength conversion material layer (140) absorbs a part of the blue excitation light and emits an excited light. The color coordinate of the excited light is within the pre-configured color area, so that a mixed light combined by the excited light and the remaining blue excitation light not absorbed by the wavelength conversion material layer (140) exits the wavelength conversion material layer (140). The color coordinate of the mixed light is closer to the pre-set blue light color coordinate than the color coordinate of the blue excitation light.
