Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0025] see figure 1 , figure 2 as well as image 3 , the micro-pipe velocimeter of the present invention includes a simulator and a velocimeter.
[0026] The simulator includes an infusion tube 1 and a container (for example, an infusion bottle) for holding a liquid 2, and the infusion tube 1 with different calibers can be selected according to the simulated human tiny pipeline (for example, a blood vessel, aqueduct of the midbrain). Connected with the container, the container and the infusion tube are all communicated with the external environment, simulating a stable pressure environment (such as intracranial pressure) in the human body, and the infusion tube 1 drains the liquid 2 to the velocimeter below, simulating body fluid (for example, blood , cerebrospinal fluid) flow in the tiny channels of the human body. Liquid 2 is obtained b...

The invention provides a micro-pipe velocimeter and a velocity measurement method thereof. The velocimeter includes a simulator and a speedometer; the simulator includes a container and a drainage pipeline, wherein the container can ascend, descend and rotate, and the drainage pipeline is connected with the container; the speedometer includes a control panel, a measuring cup and a precise weighingplatform, wherein the measuring cup is used for collecting liquid drained from the container, and the precise weighing platform is used for weighing the liquid in the measuring cup; the control panelincludes a man-machine interface and a speed measurement and control unit. When the liquid flows into the measuring cup through the drainage pipeline, the speed measurement and control unit calculates the flowing speed of the liquid in the drainage pipeline according to the liquid density read from the interface, the diameter of the drainage pipeline, the weight of the liquid in the measuring cupand the duration of the in-measuring-cup liquid continuous change process, and outputs the calculation result to the interface. The micro-pipe velocimeter and the velocity measurement method thereofsolve the problem that the flow velocity in vessels of the human body can not be directly measured in the prior art, and the velocimeter and the method have very important scientific-research, socialand economic benefits.
Description
technical field [0001] The invention relates to a measuring instrument, in particular to a velocimeter for simulating and measuring tiny pipes of a human body. Background technique [0002] Hydrocephalus is a common disease in neurosurgery. Because of its high incidence, many complications, and high disability rate, it has always been a difficult problem in neurosurgery treatment. Because its pathogenesis is not completely clear, the predisposing factors are various, and the treatment methods are different for different causes, the curative effect varies widely, and postoperative complications are common. Therefore, there is still a lack of effective treatment for different types of hydrocephalus. method. Due to its unclear pathogenesis, the postoperative curative effect is not satisfactory. After a long period of research, it has been found that stenosis or blockage of the aqueduct of the midbrain is an important cause of hydrocephalus. Then, after the aqueduct of the mid...
