Pressing position on the corresponding described simulated blood vessel of described 1 ~ N number of simulation blutpunkte difference, namely the pressure transducer installed under corresponding described position, when External Force Acting is in described pressing position, pulse can be experienced and beat, corresponding pressure transducer output pressure signal.
Described process and display unit are for showing in operating process bleeding time, the data of hemorrhage total amount, bleeding part pilot lamp, the large bezel of pressure;
Described operating unit comprises control knob, and operator is operated by selected bleeding part, and teacher carries out the setting of bleeding time and amount of bleeding by control knob simultaneously, and demarcates pressing dynamics.
When carrying out simulating hemorrhage, described process and display unit can show the size of hemorrhage total amount in operation, the hemorrhage time, corresponding bleeding part pilot lamp can be bright, described blutpunkte pilot lamp can glimmer, now, pressing haemostatic is carried out at described pressing position, pressure acquisition processing unit changes into digital pressure signal the pressure signal that the described pressure transducer at correspondence pressing position exports, with little, in, the form of large three kinds of pilot lamp is presented on described process and display unit, along with the change of pressure, the real-time amount of bleeding in simulation blutpunkte also can change, the pilot lamp flicker frequency of the blutpunkte of impact simulation simultaneously, increasing pulse Beating Rate and should increase along with blood loss, otherwise pulse Beating Rate should reduce, and then by the air pump described in control, the switch of solenoid valve realizes.
The invention has the beneficial effects as follows:
1) gas pressurized device of the present invention, by at least one rigidity cavity, at least one current limiting element, when gas by when the air intake opening and the gas outlet that are provided with the rigidity cavity of current limiting element by chain supercharging, form pulse to beat system, pulse feel and dynamics true to nature, structure is simple, rationally distributed, greatly saves production cost;
2) control system can be monitored and be shown pressing dynamics and hemorrhage total amount, bleeding stopping period and hemorrhage size in real time, the Practical Courses that it is not only only student at school learns and independence training under class, specialty creates a simulation training platform with the training of layman, the more important thing is, the achievement which ensuring simulation training can be transformed in clinical practice effectively goes.
Accompanying drawing explanation
Fig. 1 is the functional structure chart of simulation pressing haemostatic device.
Fig. 2 is filtering supercharging device structural representation.
Wherein: beat system, 11 air pumps, 12 filtering supercharging devices, 13 simulated blood vessels, 14 solenoid valves, 2 control system, 21 pulses of 1 pulse are beaten control module, 22 pressure acquisition processing units, 23 process and display unit, 24 operating units, 131 pressure transducers, 120 rigidity cavitys, 121 air intake openings, 122 gas outlets, 123 current limiting elements.

Teacher, by operating unit 24 nominal pressure value range, arranges bleeding time maximal value, hemorrhage total amount maximal value;
Student is undertaken simulating the operation of hemorrhage pressing haemostatic by operating unit 24 selection part, in process and display unit 23, bleeding part position indicator lights, be positioned at the hemorrhage pilot lamp fast blink of simulation blutpunkte, now, student applies pressing force at the pressing position of corresponding simulated blood vessel 13, pressure signal is exported to pressure acquisition processing unit 22 and is carried out analyzing and processing by the pressure transducer 131 simultaneously under this position, when the press pressure that student applies is less than calibration range value, be positioned at bezel on process and display unit 23 bright, when the press pressure applied is within the scope of this, middle pilot lamp is bright, when the press pressure applied is greater than this value range, large pilot lamp is bright, due to different pressing forces, real-time amount of bleeding changes, hemorrhage pilot lamp flicker frequency is caused to change, simulate pulse frequency to change along with the change of amount of bleeding simultaneously, this data processing of information passes to pulse and to beat control module, and then regulate the switch control rule pulse of air pump and solenoid valve beat and then realize the change of pulse frequency, in operating, the time used exceeds bleeding time maximal value, decision failure, when in operation, hemorrhage total amount exceeds hemorrhage total amount maximal value, decision failure.
Concrete operations judge scheme:
1: hemostasis success status
When pressing dynamics is in correct scope, after a period of time, on (about 5-10s) model, bleeding part pilot lamp extinguishes, the running time of numeral method this time hemostasis on facial mask be total amount of losing blood;
If pressure indicator light place green light represents the hemostasis success that pressing dynamics is correct, if when red represents that pressing force spends large hemostasis success;
Hummer has corresponding prompting; Pulse is beaten always, two minutes inoperation automatic shutdowns, shortly exits by < reset > button;
2: hemostasis status of fail
After running time or total amount of losing blood exceed the maximal value of setting, stop blooding unsuccessfully;
Hummer has corresponding prompting; " FAIL " flickering display at hemorrhage total amount place;
The asphygmia of model person, shortly exits by < reset > button;
Wherein bleeding time display 1 represents that this operation failure is because the running time exceeds permission maximal value;
Wherein bleeding time display 2 represents that this operation failure is because total amount of losing blood exceeds permission maximal value.
The above, be only present pre-ferred embodiments, not any pro forma restriction done to the present invention, all any simple modification above embodiment done according to technical spirit of the present invention, equivalent variations and modification, still belong in the scope of technical solution of the present invention.
