Embodiment one:
Present embodiment discloses a kind of filling of bladder state estimating system, as shown in Figure 1, comprising:
Optic probe 2, described optic probe 2 is arranged in wall of urinary bladder 1, also receives the probing light after wall of urinary bladder scattering for emission detection light, and sends the intensity signal of the probing light after wall of urinary bladder scattering received.Due to the tissue that wall of urinary bladder 1 is very soft, electronic device itself is difficult to thereon machinery preferably and fixes, therefore need to carry out otch in wall of urinary bladder 1, device implanted in wall of urinary bladder 1, after by the healing of otch device to be wrapped in wall of urinary bladder 1 that to realize machinery fixing.
Signal processor 3, described signal processor 3 for receiving described intensity signal, and according to the corresponding relation of described intensity signal and the filling of bladder state pre-set and intensity signal, obtains filling of bladder state.
Described in the present embodiment, signal processor 3 can also be positioned at body, as long as there is communication connection between itself and described optic probe 2, the intensity signal from described optic probe 2 can be received, and according to the corresponding relation of described intensity signal and the filling of bladder state pre-set and intensity signal, obtain filling of bladder state.
Described filling of bladder state estimating system also comprises:
The power supply 4 be connected with described optic probe 2, for powering for described optic probe 2.
Along with the change of filling of bladder state, wall of urinary bladder 1 thickness can produce corresponding change, also corresponding change can be there is in the scattered power of wall of urinary bladder 1 pair of probing light, thus the probing light intensity signal after wall of urinary bladder 1 scattering that receives of optic probe 2 is also just different, so described intensity signal can reflect filling of bladder state.In addition, owing to working as filling of bladder state one timing, the motion of exterior mechanical extruding and patient can not change the thickness of wall of urinary bladder significantly, and therefore the motion of exterior mechanical extruding and patient also can not affect the intensity signal of mensuration.The mensuration filling of bladder status system that then the application provides has stronger capacity of resisting disturbance, measures effectiveness comparison good.
In addition, the filling of bladder state estimating system provided due to the present embodiment is not be arranged on bladder inside, does not therefore have blocking urethra, makes lithogenous risk.And the filling of bladder state estimating system that the present embodiment provides optically measures filling of bladder state, without the need to analyzing bladder or the stressed of wall of urinary bladder, therefore the analyzing and processing process in its later stage is fairly simple.
Due to the difference of bion, so the corresponding relation of the filling of bladder state pre-set and intensity signal is for a certain particular individual.Therefore, after wall of urinary bladder 1 implants described optic probe 2, can be demarcated described filling of bladder state estimating system in conjunction with urodynamics tester by urodynamics principle, obtain the intensity signal under different filling of bladder state, set up the corresponding relation of filling of bladder state and intensity signal, with make the corresponding relation of filling of bladder state and intensity signal correspond to its individuality that is suitable for.
