Detailed description of the invention
Set forth the present invention further below in conjunction with Figure of description, and give embodiments of the invention.
This cavity pressure monitoring device, comprise inductive probe 1, pressure conduction body 2 and pressure display unit 3, described inductive probe 1 is arranged on one end of pressure conduction body 2, and described pressure display unit 3 obtains the detected pressures of inductive probe by connected pressure conduction body 2; Wherein said pressure conduction body 2 is any one in plain conductor, hydraulic conduction rod or endoscope's pipeline.
Described inductive probe 1 is the micro pressure sensor being furnished with parcel shell.
Described inductive probe 1 is strain gauge pressure sensor or ceramic pressure sensor.
In actual clinical is used, the device of this cavity pressure monitoring can adopt following three kinds of versions:
One, as shown in Figure 1.
Inductive probe 1 is arranged on can stretch into human body device dirty in the far-end of pressure conduction body 2, and pressure display unit is arranged 3 at the near-end of pressure conduction body 2; Pressure conduction body 2 described in this monitoring of structures is plain conductor.
The device of this cavity pressure monitoring using the pressure in patient's body cavity via an elongated wire as pressure conduction body 2, by this wire by the pressure display unit 3 of pressure transmission required for inductive probe 1 to the wire other end.The change of the pressure in patient's body cavity or in organ pipe, the induced signal that can be received by inductive probe 1, and by this Signal transmissions to outside pressure display unit 3, so that doctor can understand the change of patient's cavity internal pressure at any time, make corresponding technical measures.
Its two, as shown in Figure 2.
The pressure conduction body 2 adopted is an elongated hydraulic conduction rod 4, inductive probe 1 and pressure display unit 3 are sequentially arranged on the same one end (near-end) can stretching into the dirty interior hydraulic conduction rod 4 of human body device, by stretching into the other end (far-end) of the hydraulic conduction rod 4 of human body organ inner bore, by experienced pressure conduction to the hydraulic conduction rod inductive probe 1 of 4 other ends and pressure display unit 3, demonstrated the actual pressure condition in cavity by pressure display unit 3.The one end (far-end) of the hydraulic conduction rod 4 that this root is elongated is stretched in the cavity fluids needing detected pressures, the other end (far-end) extends to outside patient body, make it to be connected with the pressure display unit 5 with pressure inductive probe, form the pressure display unit 5 of band pressure transducer.Surrounding due to hydraulic conduction rod 4 is filled with the liquid in patient's body cavity, the change of patient body's cavity pressure can be transferred to external pressure inductor by liquid via this root hydraulic conduction rod 4, and through pressure inductor, corresponding pressure signal is shown on pressure display unit, be convenient to the change that doctor can understand patient's cavity pressure at any time, make corresponding technical measures.
Its three, as shown in Figure 3.
Utilize endoscope 6 as the carrier of pressure conduction body, inductive probe 1 and endoscope end are integrated, lead to pressure display unit 3 by a wire (special wire combined with endoscope pipeline 11) shape pressure conduction body 2 from endoscope rear portion, form the pressure monitoring device depending on endoscope.When doctor carries out endoscopic surgery operation, endoscope 6 can enter in patient's body cavity with inductive probe 1.At this moment the pressure in patient's body cavity can be detected by the micro pressure induction apparatus of endoscope 6 head end, and be transferred to external pressure display unit 3 by wire (special wire combined with endoscope pipeline 11), demonstrate the force value monitored.
Fig. 4, Fig. 5 are the structural representations of the inductive probe that the present inventor adopts at present, its concrete structure and operation principle as follows:
1, strain gauge pressure sensor (Fig. 4): this sensor operating principles is that extraneous pressure is applied to the strain resistor 7 be adsorbed on matrix material 8, this strain resistor 7 is made to produce mechanical deformation, thus generation resistance variations, convert force value as electronic signals to and show.
2, ceramic pressure sensor (Fig. 5): pressure acts directly on the front surface of ceramic diaphragm 10, diaphragm is made to produce small deformation, thick-film resistor 9 is printed on the back side of ceramic diaphragm 10, connect into a Wheatstone bridge (closing bridge), due to the piezoresistive effect of varistor, the voltage signal making electric bridge produce a highly linear be directly proportional to pressure, also be directly proportional to driving voltage, converts force value reality to out.
Below be only several basic form of implementation that the present inventor provides according to the technical program.The improvement of some necessity can be carried out according to above-mentioned basic intention in clinical application.
