The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further.
Examples of implementation 1: wireless uterine contraction pressure probe:
As shown in Figure 1, be strain chip uterine contraction pressure measurement circuitry, strain chip uterine contraction pressure probe can adopt two foil gauges (half-bridge) or four foil gauges (full-bridge) mode, when being subject to external pressure, foil gauge produces distortion, the resistance value of foil gauge changes thereupon, thereby makes electric bridge unbalance, produces and the proportional voltage of this pressure.Vc represents voltage among the figure.
As shown in Figure 2, be the gasbag-type uterine contraction pressure measurement circuitry of similar blood pressure measurement, gasbag-type uterine contraction pressure probe, ventilating control: for guaranteeing in the air bag certain initial pressure is arranged, need to inflate in advance to air bag the intrinsic pressure 2mmHg-10mmHg that rises to.Come the work of control pump by the gasbag pressure value that records, for the pressure that guarantees air bag in the preset value scope, guarantee pressure in set point by the control inflationtime simultaneously, exempted the common air valve that needs venting.
Among Fig. 1 and Fig. 2:
Sensor connects the differential amplification filter circuit, then connects master controller, and the differential amplification filter circuit is used for the signal that sensor comes is carried out differential amplification, filtering and A/D conversion, calculates real-time uterine contraction force value through master controller.Also comprise charging circuit, battery and power control circuit.
According to the characteristics of uterine contraction, when stages of labor begins, the uterine contraction persistent period lack (about 20～30 seconds) and a little less than, later on along with progress of labor, especially arrive the active phase later stage, uterine contraction longer duration (40～50 seconds) and strength increase.When the palace mouth is opened full-time, the uterine contraction persistent period is 1 minute, consider simultaneously when the uterine contraction pressure probe places at the bottom of the palace position, be vulnerable to anemia of pregnant woman's breathing (under the rest state, respiratory frequency is 12-20 times/minutes), the impact of fetal movement and anemia of pregnant woman's aspects such as movement, the digital signal that collects changes faster target signal filter through digital filtering with these more relatively, obtains accurately uterine contraction force value.
Radio receiving transmitting module (such as the NRF24 series of Nordic company, the cc series of TI company or the modules such as si series of silicon lab company) links to each other with master controller, for information such as the uterine contraction pressure that receives master controller output, battery electric quantity, probe duties.
Can arrange the communication channel of uterine contraction probe, sensor 's number etc. by the display screen on the probe, also can show the information such as the blowing pressure value, uterine contraction force value, uterine contraction pressure probe battery electric quantity and probe duty.
Examples of implementation 2:I font strain chip uterine contraction pressure probe:
Adopt the symmetric double cantilevered fashion, two cantilevers: I type shell fragment, in other words conj.or perhaps two T-shaped bottoms docking, similar " worker " font in other words, see the I type shell fragment 12 of Fig. 4, force analysis such as Fig. 8:
I shape shell fragment one end is fixed, the other end is unsettled, when measuring uterine contraction pressure, adopt two resistance strain gages (the first resistance strain gage 16 and the second resistance strain gage 17) to stick on respectively 1/4th and 3/4ths places of I shape shell fragment, the counter-force N that probe face 14 pressure P and shell fragment produce, cause shell fragment to deform, cause the resistance-strain sheet resistance to change, go out the size of uterine contraction pressure by processing afterreactions such as amplifying circuits.Because the existence of N place node has cushioned the variation of pressure, so that the active position of the Voltage-output that resistance strain gage deformation produces and P is substantially irrelevant.
F is active force, and l is the arm of force.
l
1Be the arm of force of active force f to R1
l
2Be the arm of force of active force f to R2
R1, R2 are resistance strain type sensor
If the total length of flexure strip is L, R1 is fixed on apart from left end 3L/4 place, and R2 is fixed in apart from left end 1L/4 place, and R1 and R2 are at a distance of being L/2 for half of total length L; Under the effect of active force f, the left side of flexure strip is bent downwardly R2 and is pressed short resistance decreasing, and fixing point A can be rotated counterclockwise, and right half part is bent upwards R1 and is elongated the resistance change greatly; In the electric bridge that forms, voltage variety and △ R1-(-△ R2)=△ R1+ △ R2 is proportional,
Power f expresses with moment the impact of R1 R2,
Moment to R1 is: M1=f * l1
Moment to R2 is: M2=f * l2
To the moment of R1, R2 be:
M=?M1+M2?=?f?*?l1?+?f?*?l2=?f?*?（l1?+?l2?）?=?f?*L/2。
Active force is between R1 and the R2, and it is to the arm of force l of R1 and R2
1, l
2Sum is half of flexure strip length; Because variable quantity and the △ R1+ △ R2 of electric bridge are proportional, the change in location of the application point of power f does not affect moment M=M1+M2=f* L/2 again, and only the size of power is influential to moment;
Experimental verification:
The method of testing of popping one's head in by the uterine contraction of standard detects the uterine contraction probe that adopts new sensing mode, counterweight is placed on the diverse location of pressure sensitive face, the uterine contraction force value that obtains differs less than 4%, and the probe of employing T font structure, the uterine contraction value that obtains differs and might surpass 30%, can think that new transducing part design is far superior to traditional transducing part design, the increment of uterine contraction numerical value and the position of active force are substantially irrelevant, high conformity, technique is simple, and is easy to detect.
Adopt new I font balanced structure design, eliminated the impact of trail force load position based, improve precision, improve the performance that uterine contraction is measured.
Examples of implementation 3: detachably fixedly hat type ultrasonic probe or detachably fixing hat type uterine contraction pressure probe:
Its locking cap adopts detachable fixedly hat type locking cap, locking cap by screw thread and ultrasonic probe or uterine contraction pressure probe detachably fixedly hat type be connected, the screw thread that is arranged on ultrasonic probe or the uterine contraction pressure probe main body is the concave screw thread, after the locking cap dismounting, detecting head surface is smooth, does not have projection.
Examples of implementation 4: examples of implementation 1 to 3 are made up, multiple probe can be arranged, such as 1 and 2 combinations, 1 and 3 combinations, 2 and 3 combinations, 1,2,3 combinations.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
