The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of automatic filling device detecting for urinating hydromechanics, it comprises peristaltic pump 1, inject pump 2, liquid containing bottle 3, threeway 4, T-shaped pipe A5, T-shaped pipe B16, pressure catheter 6 and pressure transducer 7, the inlet of peristaltic pump 1 is connected with liquid containing bottle 3 by pipeline, the liquid outlet of peristaltic pump 1 is by a port of pipeline connecting T-shaped pipe A5, liquid containing bottle 3 is also by a port of pipeline connecting tee 4, inject the liquid in-out mouth 8 of pump 2 by another port of pipeline connecting tee 4, the 3rd port of threeway 4 is by another port of pipeline connecting T-shaped pipe A5, a port of T-shaped pipe B16 connects pressure catheter 6, another port Bonding pressure sensor 7 of T-shaped pipe B16, the 3rd port of T-shaped pipe A5 is by the 3rd port of pipeline connecting T-shaped pipe B16, on the pipeline of connection peristaltic pump 1 and T-shaped pipe A5, be provided with control valve A9, on the pipeline of connection liquid containing bottle 3 and threeway 4, be provided with control valve B10, on the pipeline of connecting tee 4 and T-shaped pipe A5, be provided with control valve C11.
It also comprises controller 12, and described control valve A9, control valve B10, control valve C11 are electromagnetic valve, controller 12 by circuit respectively with peristaltic pump 1, inject pump 2, control valve A9, control valve B10 and control valve C11 and be connected.
Described injects pump 2 as shown in Figure 2, and it comprises syringe 13, Worm and worm-wheel gearing 14 and motor 15, and the logical Worm and worm-wheel gearing 14 of motor 15 is connected with syringe 13, and the liquid in-out mouth 8 of syringe 13 is by pipeline connecting tee 4.
Work process of the present invention is as follows: when needs pour into peristaltic pump 1, control valve B10 controlled by controller 12 and control valve C11 closes, control valve A9 conducting, liquid is driven and is flow through after control valve A9 by peristaltic pump 1, enters human body successively through T-shaped pipe A5, T-shaped pipe B16, pressure catheter 6.When needs are with injecting pump 2 while pouring into, control valve A9 controlled by controller 12 and control valve B10 closes, control valve C11 conducting, injects liquid in pump 2 after threeway 4, control valve C11, enters human body successively through T-shaped pipe A5, T-shaped pipe B16, pressure catheter 6.Thereby when carrying out bladder pressure, automatically adopt peristaltic pump 1 to pour into; While carrying out urethra pressure mensuration, automatic employing is injected pump 2 and is poured into.When injecting pump 2 while needing feed liquor, controller 12 is controlled control valve B10 conducting, control valve C11 closes, and injects pump 2 and enters drawing liquid state, and the liquid in liquid containing bottle 3 enters the syringe 13 of injecting pump 2 through control valve B10, threeway 4.Therefore only need to set in advance the minimum liquid storage amount of syringe 13, when controller 12 just can the liquid in syringe 13 be less than minimum liquid storage amount, conducting control valve B10, closed control valve C11 automatically, driving is injected pump 2 and is carried out liquid feeding, greatly facilitates clinical practice.Controller 12 can will be injected the calculating of pump 2 speed or inject position limit switch as determining whether the foundation that reaches minimum liquid storage amount.
