FIG. 1 is a schematic view of a syringe, an injection practice simulated arm, and an injection practice recording / reproducing apparatus that are examples of the present embodiment.
The syringe 102 includes a piston 105, a syringe 106, and an injection needle 107. A first acceleration sensor 108 and a transmitter / transmitter 109 are provided on the axis of the piston 105, and a tip portion of the piston 105 to be inserted into the syringe 106 is formed by a conductive rubber plug 110.

  A first acceleration sensor 108 provided on the piston 105 detects an angle between the axis of the piston 105 and the ground (hereinafter referred to as “first angle”) and a moving speed of the syringe 102 and outputs the detected speed to the transmitter / transmitter 109. To do.

  The transmitter / transmitter 109 converts the first angle input from the first acceleration sensor 108 and the moving speed signal of the syringe 102 into digital data, and transmits the digital data to the injection skill recording / reproducing apparatus 104 wirelessly. Further, the transmitter / transmitter 109 also transmits a long wave. The transmitter / transmitter 109 is electrically connected to the rubber plug 110 and outputs a long wave to be transmitted to the rubber plug 110.

  The inside of the syringe 106 is filled with a conductive liquid 111 so as to come into contact with the rubber stopper 110 of the piston 105. Therefore, a long wave transmitted from the transmitter / transmitter 109 is transmitted to the conductive liquid 111 through the rubber plug 110.

  The injection needle 107 is made of a conductive metal, and is provided on the side opposite to the side where the piston 105 of the syringe 106 is inserted so as to be in contact with the conductive liquid 111 filled in the syringe 106. . Therefore, the long wave transmitted from the transmitter / transmitter 109 is also transmitted to the injection needle 107 via the rubber plug 110 and the conductive liquid 111. The detailed configuration of the syringe 102 will be described later with reference to FIG.

  The injection practice simulated arm 103 includes a rubber sheet 112, a long wave receiving unit 113 and a simulated blood vessel 114 provided inside the rubber sheet 112, and a second acceleration sensor 115 provided on the axis of the simulated blood vessel 114. .

  The rubber sheet 112 is a conductive rubber. When the injection needle 107 of the syringe 102 is pierced into the rubber sheet 112, a long wave is transmitted through the injection needle 107.

  The long wave receiving unit 113 is electrically connected to the rubber sheet 112, and receives a long wave transmitted to the rubber sheet 112 when the injection needle 107 is stuck in the rubber sheet 112. Then, a needle signal indicating that the injection needle 107 has been inserted into the injection practice simulated arm 103 is generated. The rubber sheet 112 is also electrically connected to a USB interface 116 (hereinafter referred to as “USB I / F 116”), and the generated needle signal is output to the injection skill recording / reproducing device 104 via the USB I / F 116. To do.

  On the other hand, the second acceleration sensor 115 provided on the axis of the simulated blood vessel 114, that is, in the inside thereof, detects an angle formed by the simulated blood vessel 114 and the ground (hereinafter referred to as “second angle”). The second acceleration sensor 115 is connected to the USB I / F 116 and outputs the detected second angle to the injection skill recording / reproducing device 104 via the USB I / F 116. The details of the injection practice simulated arm 103 will be described later with reference to FIG.

  The injection practice record / playback device 104 shows computer graphics indicating the movement of the syringe 102 and the movement of the syringe 102 based on the first angle, the second angle, and the needle signal input from the syringe 102 and the injection practice simulated arm 103. The data is displayed on a display unit such as a display. Details of the injection practice recording / reproducing apparatus 104 will be described later with reference to FIG.

Next, the syringe 102 will be described with reference to FIG.
FIG. 2 is a functional block diagram showing a configuration centering on the first acceleration sensor 108 and the transmitter / transmitter 109 of the syringe 102.

  The first acceleration sensor 108 is a three-axis acceleration sensor, detects an angle with respect to the ground, detects acceleration in a three-dimensional direction (X direction, Y direction, Z direction), and based on the detected acceleration, Calculate the speed in the direction. The first acceleration sensor 108 includes a first angle detection unit 202 and a speed detection unit 203.

  For example, when the syringe 102 is moved by a trainee or the like, the first angle detection unit 202 detects the first angle based on the movement. Moreover, the speed detection unit 203 detects the acceleration (X direction, Y direction, Z direction) of the syringe 102 based on the movement. Then, the speed detection unit 203 integrates the detected acceleration for each unit time, and calculates the speed (X direction, Y direction, Z direction) at which the syringe 102 moves. The first angle and speed detected by the first angle detection unit 202 and the speed detection unit 203 of the first acceleration sensor 108 are output to the transmitter / transmitter 109 as an analog first angle signal and speed signal.

  The transmitter / transmitter 109 includes a power source 204, a switch 205, an A / D converter 206, a short-range wireless transmission unit 207, and a long wave transmission unit 208.

  The power supply 204 supplies power to each block of the first acceleration sensor 108 and the transmitter / transmitter 109. However, the power source 204 is connected to the A / D converter 206, the short-range wireless transmission unit 207, and the long wave transmission unit 208 via the switch 205, and these are only when the switch 205 is in the “on” state. Electric power is supplied to each block. Note that the switch 205 is normally in the “off” state, and is in the “on” state triggered by the detection of the acceleration of the first acceleration sensor 108. That is, when the speed detection unit 203 of the first acceleration sensor 108 calculates the speed, power is supplied from the power source 204 to the A / D converter 206, the short-range wireless communication unit, and the long wave transmission unit 208. The block is activated. Further, when the switch 205 is switched from “OFF” to “ON”, the switch 205 maintains “ON” for a predetermined time (for example, 5 minutes).

  The A / D converter 206 is electrically connected to the first acceleration sensor 108. The A / D converter 206 converts the first analog angle signal and the velocity signal respectively input from the first angle detection unit 202 and the velocity detection unit 203 of the first acceleration sensor 108 into digital data, and converts the first angle signal to the first angle.

The short-range wireless transmission unit 207 is, for example, a Bluetooth ( registered trademark ) transmitter, performs predetermined modulation processing on the first angle information and speed information obtained from the A / D converter 206, and is an injection made of a personal computer (to be described later). This is transmitted to the practical skill recording / reproducing device 104.

  On the other hand, the long wave transmission unit 208 of the transmitter / transmitter 109 is a transmitter that transmits long waves. When the injection needle 107 (see FIG. 1) of the syringe 102 is stuck in the injection practice simulated arm 103, when a long wave is transmitted from the long wave transmission unit 208, the long wave is converted into the rubber plug 110, the conductive liquid 111, and the conductive liquid 111. This is transmitted to the injection practice simulated arm 103 via the injection needle 107.

Next, the injection practice simulated arm 103 will be described with reference to FIG.
FIG. 3 is a functional block diagram of the simulation arm 103 for injection practice.
When the long wave receiving unit 113 receives a long wave from the injection needle 107 of the syringe 102 through the rubber sheet 112, the long wave receiving unit 113 generates a signal indicating that the syringe 102 has been punctured (hereinafter referred to as a “needle needle signal”). The data is output to the injection skill recording / reproducing apparatus 104 via / F116. The puncture needle signal is a binary signal indicating logical “true” or “false”. When the injection needle 107 of the syringe 102 contacts the rubber sheet 112, the puncture needle signal output from the long wave receiving unit 113 is logical. Switch from “false” to “true”.

  The second acceleration sensor 115 is a triaxial acceleration sensor, for example, and is a sensor that detects an angle with respect to the ground. As described above, the second acceleration sensor 115 detects a second angle, which is an angle formed by the simulated blood vessel 114 of the simulated arm and the ground, and outputs the second angle to the A / D converter 305.

  The A / D converter 305 converts the second angle information input from the second acceleration sensor 115 from analog to digital to generate second angle information. Then, the second angle information is output to the injection practice recording / reproducing device 104 via the USB I / F 116.

An operation unit 409 including a keyboard and a pointing device such as a mouse is connected to the control unit 408.
The control unit 408 controls the short-range wireless reception unit 402, the recording processing unit 403, the nonvolatile recording medium 404, the reproduction processing unit 405, and the display control unit 406.
