The similar blood pressure and pacemaker 300 includes a case 310, a fluid pipe 320 disposed at least partially inside the canine 200 and generating a pumping pulse similar to blood pressure by a fluid supplied from the outside, A fluid bag 330 disposed inside the case 310 and connected to the fluid pipe 320 to supply the fluid to the fluid pipe 310 or to recover the fluid supplied to the fluid pipe 320, 330 to the intensity corresponding to the intensity waveform of the like pulse.

The case 310 may be implemented in a box shape and disposed inside or outside the canister 200.

A first check valve 323-1 and a second check valve 323-2 are provided in a part of the fluid pipe 320 and a first check valve 323-1 and a second check valve 323-2 are provided, And the fluid bag 330 can be connected to each other by the connection pipe 323. Accordingly, the fluid flowing in the fluid pipe 320 flows only in one direction like the blood flowing in the blood vessel of the human body. In other words, when the fluid F is supplied to the fluid pipe 320, the first check valve 323-1 is opened and the second check valve 323-2 is closed as shown in FIG. 4 (a) do. When the fluid F is recovered from the fluid pipe 320, the first check valve 323-1 is closed and the second check valve 323-2 is opened as shown in FIG. 4 (b). Accordingly, the fluid F flows only in one direction, that is, clockwise direction, in the fluid pipe 320. Here, the fluid pipe 320 and the connection pipe 323 may be connected by a three-way valve controlled by the controller 500 so that the fluid F can flow only in one direction. That is, when the fluid F is supplied to the fluid pipe 323, the three-way valve connects the connection pipe 320 and one end of the fluid pipe 320, and the fluid F is recovered from the fluid pipe 323 A three-way valve may connect the connection pipe 320 to the other end of the fluid pipe 320.

The fluid tube 320 may include a measurement unit 322 formed of a silicone material having elasticity similar to that of a real blood vessel of a human body, for measuring a blood pressure similar to a blood pressure. For example, the fluid tube 320 may be formed of an annular hard tube 321 formed of a hard material, and a portion of the annular tube 321 may be a measurement portion 322. Accordingly, the measuring part 322 contracts or expands due to the pressure of the fluid supplied by the fluid bag 330, thereby generating a similar blood pressure and a similar pulse.

The fluid bag 330 may be formed of a silicone material having an elastic force. The fluid bag 330 is inflated or contracted by external pressure to supply fluid to the fluid tube 320 or to recover the fluid in the fluid tube 320.

The pulse-like driving part 340 has a similar pulse-driving plate 341 disposed inside the case 310 to be in contact with the fluid bag 330, one end connected to the pulse-like driving plate 341 and the other end connected to the case 310 And a solenoid 343 which is controlled by the control unit 400 and moves the pacemaker driving rod 342 in accordance with the intensity waveform of the like pulse.

The pseudo blood pressure and pacemaker 300 may further include a pressure intensity controller 350 for controlling the pressure inside the fluid pipe 320 by pressing or releasing the fluid bag 330. That is, the pressure intensity regulating unit 350 includes a screw 351 that penetrates the case 310 and is screwed to the case 310, one side of which contacts the fluid bag 330 and the other side of which is coupled to the screw 351, And a pressure plate 352 for pressing or releasing the fluid bag 330 by rotation of the fluid bag 351. The pressure intensity controller 350 controls the pressure of the fluid bag 330 to control the pressure of the fluid tube 320. That is, the pressing plate 352, which is moved by the rotation of the screw 351, presses or releases the fluid bag 330 to adjust the pressure of the fluid bag 330. Accordingly, by controlling the intensity of the pressure of the fluid pipe 320, the intensity of the pulsation generated in the measuring unit 322 is adjusted. That is, when the pressure plate 352 is lowered, the volume of the fluid bag 330 is reduced. As a result, even if the drive plate 341 reciprocates, the flow of fluid generated in the fluid bag 330 is reduced, Of blood pressure measurement. Conversely, the state in which the pressure plate 352 is lifted up is suitable for measurement of blood pressure by a young person.

In addition, the pseudo blood pressure and pacemaker 300 may further include a fluid filling unit 360 for filling the fluid bag 330 with fluid or discharging the fluid filled in the fluid bag 330. The fluid filling portion 360 includes a fluid inlet 361 formed in the fluid bag 330, a valve 362 installed in the fluid inlet 361, and a compression pump 363 detachably coupled to the fluid inlet 361. [ . ≪ / RTI > The fluid filling portion 360 regulates the total amount of fluid filled in the fluid bag 330 by providing additional fluid to the fluid bag 330 or allowing the fluid filled in the fluid bag 330 to be discharged. The sound generating apparatus 500 may be selected from among well-known ones, and detailed explanations thereof are omitted here.

The simulator 100 for blood pressure and pulse measurement training may further include a sound generating device 500 to be embedded in a part of the wrist 200 to generate a quasi-coherent sound. The sound generator 500 may be implemented as a speaker and installed in at least one of the connecting portion of the upper arm 210 and the lower arm 220 of the wrist 200 and the wrist portion 230. The sound generator 500 is controlled by the controller 400 to generate a pseudo-Cortex tone. Accordingly, the medical trainee can use the stethoscope to listen to the pseudokordcov tone and measure the blood pressure.

FIGS. 7 and 8 are views for explaining the operation of the simulator for blood pressure and pulse measurement training Fig. 8 is a diagram showing a pulse strength waveform of a simulator.

5, when the control unit 400 controls the solenoid 343 of the pulse-like driving unit 340 using the intensity waveform of the similar pulse, the solenoid 343 is driven by the pulse-like driving rod 342, The pulsation driving plate 341 presses the fluid bag 330 or releases the fluid bag 330. Accordingly, the measuring portion 322 of the fluid tube 320 expands or contracts according to the intensity waveform of the similar pulse. At this time, the fluid bag 330 corresponds to the heart of the human body, and the measuring unit 322 corresponds to the blood vessel of the human body. Therefore, when the fluid bag 330 is pressed, the measurement unit 322 When the pressure applied to the fluid bag 300 is released in a state in which only the measuring part 322 is swollen rapidly, the annular sight 321, which is a narrow channel of the fluid in the measuring part 322, The measurement portion 322 is slowly contracted by flowing back to the fluid bag 330 (in the clockwise direction in the figure) As shown in Fig. 6A, the intensity waveform of the pulse actually generated in the blood vessel of the human body is approximated.

For reference, the pulse in the blood vessel of the human body has the waveform shown in Fig.

6, when the simulator 100 for blood pressure and pulse measurement training is operating, an external pressure applied to the fluid bag 330 by the screw 351 of the pressure intensity adjuster 350 is rotated Lt; / RTI > Thus, by controlling the amount of fluid ejected from the fluid bag 330 so that the intensity waveform of the pulsatile pulse generated by the measuring unit 322 of the fluid pipe 320 is adjusted as shown in FIG. 8, Simulation training can be done.
