Specific embodiment
The present invention is further explained with reference to the accompanying drawings and examples, and disposable conduit of the invention is fixed as shown in Figure 1
Structural schematic diagram of the device for mechanical pressure monitor in catheter application, catheter provided in this embodiment, including main pipeline 1
With air bag 2；Air bag 2 is arranged on the outer wall on 1 head of main pipeline；Main pipeline 1 is internally provided with drainage channel 3 and waterflood path
4；The conduction hole 5 being connected to drainage channel 3 is provided on main pipeline 1, drainage channel 3 is in communication with the outside far from one end of air bag 2；
4 one end of waterflood path is connected to air bag 2, and the other end far from air bag 2 is provided with Water filling valve 6 and pressure monitoring device 7；Water filling
Valve 6 is that check valve is used to increase the pressure of air bag 2 and makes the sufficiently expansion of air bag 2 by injecting more water；Mechanical pressure prison
7 shell of device to be surveyed to be made of the material of transparent material, one end monitors the pressure that film 10 monitors waterflood path 4 by elastic pressure,
The other end has opening to be communicated with the atmosphere, and the elastic pressure when air bag 2 expands in pressure monitoring device 7 monitors 10 stress deformation of film
It pushes instruction device 8 to be displaced to opening direction, is fixed on the compression spring 9 in pressure monitoring device 7 in the displacement of instruction device 8
Middle compressive deformation, when the pressure balance in the elastic force of compression spring 9 and waterflood path 4, instruction device 8 stops being displaced, and passes through sight
Examining the opposite displacement with transparent outer cover of the instruction device 8 in transparent pressure monitoring device 7 can estimate in waterflood path 4
Pressure, and then can judge the expansion status of air bag 2.To reach the fixed device air bag 2 of monitoring tube in patient's body
The purpose of fixing situation.
Fixing pressure monitoring device 7 shown in the structural schematic diagram of device electron pressure monitor such as Fig. 2 disposable conduit is
Electrical type monitoring device, comprising: shell, elastic pressure monitoring film 10, the controller 11, battery 12, instruction of pressure monitoring device 7
Device 8 etc..Wherein elastic pressure monitoring film 10 is the foil gauge that resistance class strain gauge can refer to model BFH120-3AA, it
Working principle be according to unbalanced pressure generate elastic strain, to change the resistance of itself.Instruction device 8 is hair
