Background technique
Human body is often caused bleeding by wound, and serious bleeding can cause life danger, with dynamic in all kinds of angiorrbagias
Arteries and veins hemorrhage risk is larger, and pressing urgent bleeding artery with hand is emergency measure, bleeding can be made to temporarily cease, artery blood flow direction is
Centrifugation, therefore artery is oppressed in one end of the nearly heart of wound to block blood source, compressing artery should select to connect below artery
The position of nearly bone, the bone face for firmly pressing to lower section achieve the purpose that temporarily to stop blooding to be closed blood vessel.
Existing wound hemostasis teaching mode uses peristaltic pump, simulation blood mainly to realize pulse beating and pressing haemostatic
Operation, such as disclose to be simulated blood with detection device, control box and peristaltic pump control and formed pulse in CN203276692 and fight
Dynamic, CN202584534 discloses the interaction of electric air pump and liquid pump, realizes fluid circulation system；Though the class model
So may be implemented pulse beating, pressing haemostatic, but use it is not very convenient, 1) its pulse beating system it is cumbersome, 2) pulse
Beating system is not only difficult to control amount of bleeding using simulation blood, but also liquid easily be lost and leak, unhygienic and in the presence of pacifying
Full hidden danger, while difficult in maintenance, needs to be replenished in time simulation blood, 3) display and instruction system are not perfect.

The output of word pressure signal；Processing and display unit, data processing, display and the display of indicator light；Operating unit, setting operation
Content and calibration.
Described 1 ~ N number of simulation blutpunkte respectively corresponds the pressing position on the simulated blood vessel, that is, corresponds to the position
The pressure sensor of lower installation can experience pulse beating, corresponding pressure sensing when external force is when the pressing position
Device output pressure signal.
The processing and display unit is used for bleeding time, the data of bleeding total amount, bleeding portion during display operation
Position indicator light, pressure size indicator light；
The operating unit includes control button, and operator is operated by selected bleeding part, while teacher can
The setting in bleeding time and amount of bleeding is carried out by control button, and pressing dynamics are demarcated.
When carrying out simulation bleeding, the size of bleeding total amount, bleeding in the processing and display unit meeting display operation
Time, corresponding bleeding part indicator light can be bright, and the blutpunkte indicator light can flash, at this point, at the pressing position
Pressing haemostatic is carried out, pressure acquisition processing unit converts the pressure signal that the pressure sensor at corresponding pressing position exports
At digital pressure signal, by it is small, in, be shown in the processing and display unit in the form of big three kinds of indicator lights, with pressure
The change of power, the simulation real-time amount of bleeding in blutpunkte can also change, while influence to simulate the indicator light flicker frequency of blutpunkte,
Increasing pulse Beating Rate and should increase with blood loss, on the contrary pulse Beating Rate should reduce, and then described by control
Air pump, solenoid valve switch realize.
The beneficial effects of the present invention are:
1) gas pressurized device of the invention, by least one rigid cavity, at least one current limiting element, when gas is logical
By chain pressurization when crossing the air inlet and air outlet for being provided with the rigid cavity of current limiting element, pulse beating system, pulse are formed
Feel is true to nature with dynamics, and structure is simple, rationally distributed, greatlys save production cost；
2) control system can monitor simultaneously real-time display pressing dynamics and bleeding total amount, bleeding stopping period and the size of bleeding,
It creates one not just for independence training under the Practical Courses study of student at school and class, profession and the training of layman
Simulation training platform, it is often more important that, it ensure that the achievement of simulation training can be effectively transformed into clinical practice.
Detailed description of the invention
Fig. 1 is the functional structure chart for simulating pressing haemostatic device.
Fig. 2 is filtering supercharging device structural schematic diagram.

Bleeding time maximum value, bleeding total amount maximum value can be arranged by 24 nominal pressure value range of operating unit in teacher；
Student carries out simulation bleeding pressing haemostatic operation by 24 selection part of operating unit, in processing and display unit 23
Upper bleeding part position indicator lights, the bleeding indicator light fast blink positioned at simulation blutpunkte, at this point, student is corresponding
The pressing position of simulated blood vessel 13 applies pressing force, while the pressure sensor 131 under this position exports pressure signal to pressure
Power acquisition process unit 22 is analyzed and processed, when student apply press pressure be less than calibration range value when, be located at processing and
Bezel is bright on display unit 23, when the press pressure of application in the range when, middle indicator light is bright, when the pressing pressure of application
When power is greater than the value range, big indicator light is bright, and due to different pressing forces, real-time amount of bleeding generates variation, and bleeding is caused to indicate
The variation of lamp flicker frequency, while simulating pulse frequency and should change with the variation of amount of bleeding, the transmitting of this data processing of information
Pulse beating control unit is given, and then the switch control pulse for adjusting air pump and solenoid valve beats and then realizes the change of pulse frequency
Change, time used is beyond bleeding time maximum value, decision failure in operated；When bleeding total amount exceeds in operation
Blood total amount maximum value, decision failure.
Concrete operations judge scheme:
1: hemostasis success status
When pressing dynamics are in correct range, bleeding part indicator light extinguishes on (about 5-10s) model after a period of time, face
The operating time and be blood loss total amount that numeral method this time stops blooding on film；
If green light indicates that pressing dynamics are correctly stopped blooding success at pressure indicator light, if the bright expression pressing force of red light
Spend big hemostasis success；
Buzzer has corresponding prompt；Pulse is beaten always, and automatic shutdown is not operated within two minutes, and short-press<resets>key and moves back
Out；
2: hemostasis status of fail
Since operating time or blood loss total amount are more than hemostasis failure after the maximum value set；
Buzzer has corresponding prompt；" FAIL " at bleeding total amount flashes display；
The asphygmia of model person, short-press<reset>key and exit；
Wherein bleeding time display 1 indicates that this operation failure is since the operating time is beyond permission maximum value；
Wherein bleeding time display 2 indicates that this operation failure is since blood loss total amount is beyond permission maximum value.
The above is only present pre-ferred embodiments, not does limitation in any form to the present invention, it is all according to
According to technical spirit any simple modification to the above embodiments of the invention, equivalent variations and modification still fall within the present invention
In the range of technical solution.
