On the circumference in face.
Preferably, the multiple pressure sensor is in parallel forms null-type bridge circuit.
Preferably, in addition to multiple current sensors corresponding to multiple pressure sensors, the central controller pass through
Multiple current sensors gather the current value of each branch road of null-type bridge circuit respectively.
Preferably, in addition to alarm module, the input of the alarm module and the output end of central controller connect.
Preferably, in addition to display module, the input of the display module and the output end of central controller connect.
The beneficial effects of the utility model are：
The utility model gathers treatment head and human contact's situation data by using multiple pressure sensors, overcomes existing
Have needs to rely on the situation that doctors experience judges treatment head exposure level in technology, realizes the objective amount to treatment head contact situation
Change detection, so as to provide effective dynamics control for doctor, and then ensure that therapeutic effect, and it is simple in construction, have good
Economic and social benefit.
In addition, the utility model also more easily detects the pressure differential of each pressure sensor by null-type bridge circuit design
Different and contact situation；By alarm module and display module, comfortable, visual operation index is provided for device operator.
The utility model can be widely applied to various high strength supersonic focus therapeutic systems.
Brief description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is a kind of electrical block diagram of embodiment of the utility model；
Fig. 2 is a kind of null-type bridge circuit schematic diagram of embodiment of the utility model；
Fig. 3 is a kind of mechanical structure schematic diagram of embodiment of the utility model.
Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.
Pressure system is innovative technique, and the purpose of the technology is optimization therapeutic effect, because doctor is in the process for the treatment of
In application pressure fixing position to treatment head.Basic conception of the present utility model is to be delivered to pressure by the size of pressure to pass
Sensor, realize that linear assessment compresses degree, therefore pressure system is achieved in that pressure sensor induction pressure.Further
, parameter can be reached bridge circuit, output signals to display screen, shown according to gear, effective dynamics control is provided for doctor
System, so as to ensure that therapeutic effect, also provides comfortable, visual operation index for device operator.
As shown in figure 1, a kind of high strength supersonic focus therapeutic head with pressure-detecting device, including central controller and
Body-contacting surface, multiple pressure sensors is evenly arranged with body-contacting surface, the output end of multiple pressure sensors is equal
It is connected with the input of central controller.The input of alarm module and the output end of central controller connect.Display module
The output end of input and central controller connects.
As shown in figure 3, body-contacting surface is circular surface, multiple pressure sensors are uniformly arranged on the circle of circular surface
Zhou Shang.
As shown in Fig. 2 in the embodiment, multiple pressure sensors are in parallel to form null-type bridge circuit.Corresponding to multiple pressures
Force snesor is provided with multiple current sensor (not shown)s, and central controller is gathered respectively by multiple current sensors
The current value of each parallel branch of null-type bridge circuit.
Specifically, the utility model installs a pressure sensor in the round frame for the treatment of head every 2cm, can be according to treatment
Head size setting sensor quantity；Each pressure sensor is connected in the branch road of a null-type bridge circuit simultaneously：Arbitrarily with
On the basis of some specific pressure sensor number, all pressure sensors are marked, are then linked into balanced bridge electricity in order
Lu Zhong, the voltage that power supply gives bridge circuit both ends according to the quantity of pressure sensor (can pass through central controller controls power supply
The voltage at given bridge circuit both ends) so that each bridge current is 5mA.When some pressure sensor either some area
The curtage of the pressure sensor in domain can detect that the pressure in the region changes when changing, according to pressure
Difference can feed back exposure level.It is good to contact when setting electric current 6.5mA≤I≤8.5mA of branch road in bridge circuit, when
8.5mA≤I is that contact is excessive.Shown according to clinic feedback, when the branch arm electric current symbol in bridge circuit more than 85%
When splice grafting touches good requirement, supersonic focus therapeutic can be effectively conducted ultrasound, and the chance for skin scald occur is considerably less；But
It is that patient does not substantially feel like oneself when in electric bridge 25% bridge current is more than 8.5mA.
Therefore it can also feed back contact and the correlation of comfort level to a certain extent.All electric parameters are super
Fed back on the display module of sound treatment head, user can be according to the change of electric bridge parameter, can be according to adjustment focus ultrasonic
The inclined degree for the treatment of head, to select optimal ultrasonic therapy incidence channel, reach optimal therapeutic effect and most suitable
Patient comfort.
The utility model gathers treatment head and human contact's situation data by using multiple pressure sensors, overcomes existing
Have needs to rely on the situation that doctors experience judges treatment head exposure level in technology, realizes the objective amount to treatment head contact situation
Change detection, so as to provide effective dynamics control for doctor, and then ensure that therapeutic effect, and it is simple in construction, have good
Economic and social benefit.In practical application, can pressure parameter or current parameters reach setting contact upper limit parameter when, or
When exposure level is not up to the lower limit parameter set, focus ultrasonic emission system is stopped, and prevents from sending out in not fully contact
High intensity focused ultrasound is penetrated, prevents the security incidents such as patient's scald.
In addition, the utility model also more easily detects the pressure differential of each pressure sensor by null-type bridge circuit design
Different and contact situation；By alarm module and display module, comfortable, visual operation index is provided for device operator.
The utility model can be widely applied to various high strength supersonic focus therapeutic systems.
Above is preferably implement to be illustrated to of the present utility model, but the invention is not limited to the reality
Example is applied, those skilled in the art can also make a variety of equivalent variations on the premise of without prejudice to the utility model spirit
Or replace, these equivalent deformations or replacement are all contained in the application claim limited range.
