Description

  The present invention relates to a medical ultrasonic diagnostic training system and a medical ultrasonic diagnostic training method.

  For example, in a medical institution, a diagnosis is performed using an ultrasonic diagnostic apparatus when diagnosing the position of a blood vessel in the body or the state of an organ in the body. When diagnosing such internal conditions, the probe consisting of the ultrasonic transmitter / receiver of the ultrasonic diagnostic device is brought into contact with the surface of the skin, the ultrasonic wave is transmitted toward the diagnostic point, and the reflected wave is received. The image obtained in this way is displayed on the monitor. The doctor or nurse diagnoses the internal condition by checking the display on the monitor.

  A doctor or nurse who operates such an ultrasonic probe has previously trained an operation method and a diagnosis method based on a monitor image using a training apparatus (see, for example, Patent Document 1). This training device artificially places arbitrary defects (diagnostic parts) from a database that records various reference flaw detection waveforms using computer to detect the position of the defect. It is something to be made.

JP 2010-49071 A

  For example, when diagnosing an actual patient, it is difficult to find the position of a blood vessel in which a blood vessel is narrowed by the patient or a stenosis in which blood flow is narrowed. However, the training apparatus evaluates a flaw detection result based on an ultrasonic reception signal of a defect artificially arranged on a plane coordinate on a test object. Therefore, although the conventional training apparatus can train the operation method of the probe for transmitting and receiving ultrasonic waves, for example, the presence or absence of stenosis of a blood vessel that restricts blood flow or the state of the blood vessel when the blood vessel is thin There was a problem that it was not possible to conduct training to find out what was going on.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

Embodiment 1
FIG. 1 is a system diagram showing Embodiment 1 of a medical ultrasonic diagnostic training system according to the present invention. As shown in FIG. 1, the medical ultrasonic diagnostic training system 10 includes a pseudo sample 20 configured to approximate a human body and an ultrasonic diagnostic training apparatus 30. In FIG. 1, the configuration of the pseudo sample 20 is shown in a simplified manner for convenience of explanation, and details will be described later.

  The ultrasonic diagnostic training apparatus 30 is configured separately from the ultrasonic oscillator 40 and the probe 140. For example, the ultrasonic diagnostic training apparatus 30 is additionally installed in an examination room in which the ultrasonic oscillator 40 and the probe 140 are already installed. Is possible.

  The ultrasonic diagnostic training apparatus 30 includes a simulated blood circulation unit 120 in which a simulated blood tank 50, a pump 60, and a backflow prevention valve 80 are disposed in the simulated blood circulation path 100 in the housing 32. The simulated blood circulation unit 120 circulates simulated blood through the simulated blood vessel 110 (indicated by a broken line in FIG. 1) formed inside the simulated specimen 20 via the simulated blood circulation path 100. In addition, since the pseudo sample 20 is mounted on the ultrasound diagnostic training apparatus 30, it is easy to carry and can be moved as appropriate.

The pseudo blood vessel 110 is provided with a pseudo stenosis portion X for training. As the simulated blood, for example, water or a liquid in which water is colored red is used. Further, in order to improve the reproducibility of training, a liquid having ultrasonic transmission characteristics similar to blood, for example, the specific acoustic impedance is set to 1.6 to 1.7 × 10 ⁵ (kg / m / sec). The adjusted liquid may be used as simulated blood.

  The simulated blood tank 50 stores a predetermined volume of simulated blood so that the simulated blood does not run out in accordance with fluctuations in the rotation speed of the pump 60. The check valve 80 is opened when the pressure of the pseudo blood vessel 110 is relatively lower than the pressure of the pseudo blood circulation path 100, and the pressure of the pseudo blood vessel 110 is relatively higher than the pressure of the pseudo blood circulation path 100. It closes when it becomes.

  The pump 60 is a roller pump that squeezes and pushes a U-shaped tube through which simulated blood flows by a rotating roller. The roller rotation speed of the roller pump is set to an arbitrary value (for example, a value corresponding to a symptom of high blood pressure or low blood pressure) so as to reproduce a blood flow and a pulse according to the diameter of the pseudo blood vessel 110 built in the pseudo sample 20. It can be set.

  The ultrasonic oscillator 40 and the probe 140 are separate from the ultrasonic diagnostic training apparatus 30, and may be purchased separately or used in advance. Therefore, when performing ultrasonic diagnostic training using the ultrasonic diagnostic training apparatus 30, simulated blood is circulated through the simulated blood circulation path 100 and the simulated blood vessel 110 by turning on the power switch and driving the pump 60. Training. In addition, since the rotation speed of the pump 60 is set to the rotation speed for training according to the assumed symptom, the trainee can concentrate on the operation of the probe 140. Further, the ultrasonic oscillator 40 is provided with a small monitor, and the trainee can perform ultrasonic diagnosis training while watching a simulated image by transmitting and receiving ultrasonic waves according to the position of the probe 140.

  The probe 140 is brought into contact with the outside of the pseudo sample 20 when performing ultrasonic diagnosis. Then, the ultrasonic wave transmitted from the probe 140 propagates through the pseudo muscle 180 and reaches the pseudo blood vessel 110. Since pseudo blood flows inside the pseudo blood vessel 110, the ultrasonic wave is reflected and received by the probe 140, and an ultrasonic reception signal is output from the probe 140. At this time, by moving the probe 140 along the surface of the pseudo sample 20, an ultrasonic image corresponding to the shape of the pseudo blood vessel 110 arranged inside the pseudo sample 20 is created.

  The pseudo blood vessel 110 is provided with a pseudo stenosis portion X corresponding to a stenosis that restricts blood flow at an arbitrary position. The pseudo stenosis portion X is prepared in a plurality of patterns in advance, and can be appropriately exchanged to enable training for detecting the presence of stenosis at different locations and training for finding the position of the stenosis. The pseudo-stenosis part X is set so that the internal flow path of the pseudo blood vessel 110 is narrowed, the flow rate of the pseudo blood is reduced, and is almost the same as the symptoms of hypertension. Therefore, even if the probe 140 is operated, it is difficult to find the pseudo-constricted portion X because the reflected wave of the ultrasonic wave is weak. However, the trainer can practice the operation method of the probe 140 in a situation close to the actual situation by repeating the training to find the position where the stenosis portion X provided in the pseudo sample 20 is present. You can increase your ability.

  The pseudo sample 20 is provided with first connection couplings 112 and 114 communicating with the pseudo blood vessel 110. On the other hand, on the upper surface of the housing 32, second connection couplings 34 and 36 communicated with both ends of the simulated blood circulation path 100 are provided.

  The pseudo sample 20 can be coupled to the first connection couplings 112 and 114 by simply placing the pseudo sample 20 on the upper surface of the housing 32 and pressing it downward. As described above, the first connection couplings 112 and 114 and the second connection couplings 34 and 36 are detachably coupled by being inserted, and the internal locking mechanism is operated by being engaged with each other to be coupled to each other. It is structured to be fixed with. Further, the operation ring provided on the outer periphery of the first connection couplings 112 and 114 can be unlocked by sliding in the axial direction. Therefore, the pseudo sample 20 and the housing 32 can be easily connected and the separation operation can be performed in a short time.

  Further, the first connection couplings 112 and 114 and the second connection couplings 34 and 36 have built-in backflow prevention valves, and the backflow prevention valves built in with the connection are opened to communicate with each other. When this occurs, each backflow prevention valve is closed to prevent liquid leakage.

[Modification of Embodiment 1]
FIG. 2 is a view showing a fixing mechanism for fixing the pseudo sample 20 to the pseudo blood circulation unit 120. As shown in FIG. 2, the actual pseudo sample 20 is manufactured not in a box shape but in a shape close to a human body, and thus is fixed by a fixing mechanism (fixing means) 170 provided on the upper surface of the housing 32. It becomes possible to train in a stable state. As the fixing mechanism 170, for example, a hook-shaped fixing member 174 is rotatably provided on the support portion 172 on the upper surface of the housing 32. The nail | claw part 176 of this fixing member 174 engages with the recessed part 22 provided in the pseudo sample 20, and the pseudo sample 20 is fixed. Since the fixing member 174 is biased to a position where it is fitted into the recess 22 by a biasing member such as a torsion spring, the claw portion 176 of the fixing member 174 causes the pseudo sample 20 to latch the recess 22. Can be fixed easily.

[Configuration example of pseudo sample 20]
FIG. 3 is a diagram schematically illustrating a configuration example of the pseudo sample 20. As shown in FIG. 3, the pseudo sample 20 has a shape corresponding to, for example, an upper body having a human head and a torso, and a pseudo blood vessel 110 made of a resin tube is disposed therein. The pseudo blood vessel 110 is connected to a model of each organ such as the heart A, liver B, stomach C, kidney D, lung E, and brain F, and is divided into an artery and a vein. Moreover, the pseudo blood vessel 110 uses a tube having a diameter corresponding to each part. Further, the pseudo blood vessel 110 is covered with a pseudo muscle 180 formed of a resin material having an ultrasonic transmission property close to that of a muscle.

  In addition to the pseudo sample 20 combining the head and the torso, for example, a pseudo sample with only an arm or a pseudo sample with only a leg is connected to the ultrasonic diagnostic training apparatus 30 to perform ultrasonic diagnostic training. Is also possible. Accordingly, a plurality of pseudo specimens 20 are prepared in which pseudo blood vessels 110 corresponding to the assumed symptoms are individually provided, and are connected to the ultrasonic diagnostic training apparatus 30 in an exchangeable manner.

  FIG. 4 is a diagram showing a modified example of a pseudo sample made of a whole body model. As shown in FIG. 4, the pseudo sample 20A made of a whole body model has a configuration closer to a human body, has both hands and both legs, and a pseudo blood vessel 110 is provided in the whole body. Therefore, the accuracy of the ultrasonic diagnosis training is further increased by the pseudo sample 20A closer to the human body. In the case of the whole body pseudo sample 20A, the pseudo stenosis portion X is provided in the pseudo blood vessel 110 as in the case of the upper body shown in FIG.

  Further, the pseudo sample 20A may be configured to be separable for each part such as the body part 200, the head part 210, the arm parts 220 and 230, and the leg parts 240 and 250. In that case, it becomes possible to use only the site | part according to the training content among the trunk | drum 200, the head 210, the arm parts 220 and 230, and the leg parts 240 and 250. FIG. Further, by providing a connection coupling as shown in FIG. 1 to the pseudo blood vessel 110 located at the boundary of each part, it is possible to facilitate connection and separation work and to prevent liquid leakage at the time of separation.

[Embodiment 2]
FIG. 5 is a system diagram showing Embodiment 2 of the medical ultrasonic diagnostic training system according to the present invention. As shown in FIG. 5, the ultrasonic diagnostic training apparatus 30A of the medical ultrasonic diagnostic training system 10A includes an ultrasonic oscillator 40, a simulated blood tank 50, a pump 60, a flow meter 70, and a backflow prevention in a housing 32. A valve 80 and a controller 90; The ultrasonic diagnostic training apparatus 30A shown in FIG. 5 has the same configuration as that of the first embodiment shown in FIG. 1 except for the flow meter 70, and therefore the same parts are denoted by the same reference numerals and description thereof is omitted. To do.

  The flow meter 70 measures the flow rate of the simulated blood flowing through the simulated blood circulation path 100 and outputs a flow rate measurement signal to the control unit 90. The control unit 90 integrates the flow rate measurement signals from the flow meter 70 to calculate the instantaneous flow rate per unit time, and the flow rate (measured value) according to the rotation speed of the pump 60 becomes a preset set value. The motor of the pump 60 is controlled.

  FIG. 6 is a flowchart for explaining the ultrasonic diagnostic training control process 1 of the second embodiment. As shown in FIG. 6, when the power switch is turned on in step S11, the control unit 90 proceeds to step S12, reads the parameters of the pump driving cycle registered in the memory in advance, and details of the current training The pump drive cycle is set according to.

  In the next step S13, the pump 60 is driven. As a result, the simulated blood stored in the simulated blood tank 50 passes through the flow meter 70 and the backflow prevention valve 80 and is supplied to the simulated blood vessels 110 of the simulated samples 20 and 20A. The simulated blood that has passed through the simulated blood vessel 110 is collected in the simulated blood tank 50 and circulated.

  In the next step S14, the flow rate measurement value measured by the flow meter 70 is read, and the instantaneous flow rate Q per unit time is calculated. Then, it progresses to step S15 and it is checked whether the measured instantaneous flow rate Q is equal to the preset target flow rate Q1. In step S15, when the measured instantaneous flow rate Q is not equal to the preset target flow rate Q1 (in the case of NO), the process proceeds to step S16, and the rotational speed of the pump 60 is adjusted by accelerating or decelerating. And the process of said S13-S15 is repeated.

  In step S15, when the measured instantaneous flow rate Q is equal to the preset target flow rate Q1 (in the case of YES), the process proceeds to S17 to check whether the power switch is off. In S17, when the power switch is off (in the case of YES), the current control process is terminated. In S17, if the power switch is on (NO), the process returns to S14, and the processes in S14 and S15 are repeated.

  The trainee moves the probe 140 along the surface of the pseudo sample 20, thereby creating an ultrasound image corresponding to the shape of the pseudo blood vessel 110 arranged inside the pseudo sample 20. Further, the trainer can practice the operation method of the probe 140 in a situation close to the actual situation by repeating the training to find the position where the stenosis portion X provided in the pseudo sample 20 is present, and the ultrasonic diagnosis You can increase your ability.

[Embodiment 3]
FIG. 7 is a system diagram showing Embodiment 3 of the medical ultrasonic diagnostic training system according to the present invention. As shown in FIG. 7, the ultrasonic diagnostic training apparatus 30B of the medical ultrasonic diagnostic training system 10B includes an ultrasonic oscillator 40, a simulated blood tank 50, a pump 60, a flow meter 70, and a backflow prevention in a housing 32. A valve 80 and a controller 90;

  Furthermore, a monitor (notification unit) 130 for displaying an ultrasonic diagnostic image is provided on the upper surface of the housing 32. The ultrasonic oscillator 40 transmits a signal having a preset frequency (for example, several MHz to several tens of MHz) to the probe 140 via the signal line 42. The probe 140 has an ultrasonic transmitter / receiver such as a vibrator or a diaphragm inside a rod-like case. Further, the probe 140 receives the ultrasonic wave reflected in the pseudo sample 20 and outputs a received signal to the control unit 90 via the signal line 44.

  The control unit 90 generates an ultrasonic image obtained based on the signal from the probe 140 and displays the ultrasonic image on the monitor 130, and compares the pre-registered stenosis image with the pseudo blood vessel 110 based on the ultrasonic image. And it is determined whether or not the presence (position) of the pseudo-stenosis portion X is detected, and the determination result is notified.

  FIG. 8 is a flowchart for explaining the ultrasonic diagnostic training control process 2 of the third embodiment. As illustrated in FIG. 8, the control unit 90 executes the processes of steps S <b> 11 to S <b> 16 (not described) described above.

  In step S15, when the measured instantaneous flow rate Q is equal to the preset target flow rate Q1 (in the case of YES), the process proceeds to step S17a to activate the ultrasonic oscillator 40. Thereby, the ultrasonic oscillator 40 transmits a signal having a preset frequency (for example, several MHz to several tens of MHz) to the probe 140 via the signal line 42. Thus, the trainee performs the training by holding the probe 140 in his hand and bringing it into contact with the surface of the pseudo sample 20.

  The ultrasonic wave transmitted from the probe 140 propagates through the pseudo muscle 180 of the pseudo specimen 20 and reaches the pseudo blood vessel 110. Since pseudo blood flows inside the pseudo blood vessel 110, the ultrasonic wave is reflected and received by the probe 140, and an ultrasonic reception signal is output from the probe 140. At this time, by moving the probe 140, an ultrasonic image corresponding to the shape of the pseudo blood vessel 110 arranged inside the pseudo specimen 20 is created. Thereby, the trainee operates the probe 140 to visually detect the image of the pseudo-stenosis part X until the image by the reflected wave from the pseudo-stenosis part X is displayed on the monitor 130.

  In the next step S <b> 18, it is checked whether or not the received signal of the reflected wave received by the probe 140 is input to the control unit 90. In step S18, when the reflected wave of the transmitted ultrasonic wave is received (in the case of YES), the process proceeds to step S19, where image data based on the received signal is generated and displayed on the monitor 130 (image generating unit). In addition, an image of the pseudo-stenosis portion X is extracted from the image displayed on the monitor 130.

  In the next step S20, it is checked whether or not an image of the pseudo-stenosis portion X is extracted from the image displayed on the monitor 130. In step S20, when the image of the pseudo stenosis part X is not extracted from the images displayed on the monitor 130 (in the case of NO), the trainee cannot find the pseudo stenosis part X (affected part). Returning to the process of step S18, the operation of the probe 140 is continued.

  In step S20, when an image of the pseudo-stenosis part X is extracted from the images displayed on the monitor 130 (in the case of YES), the trainee was able to find the pseudo-stenosis part X (affected part). In step S21, the trainee is notified of the affected area detection. As a notification method, notification may be performed by voice, or a mark indicating detection of an affected area may be displayed on the screen of the monitor 130.

  Thereby, even a beginner can easily confirm that the pseudo-stenosis part X (affected part) has been detected while operating the probe 140. The trainer can efficiently perform training for visually detecting the pseudo-stenosis portion X (affected site) that is difficult to understand from the display on the screen by repeatedly viewing the image according to the operation of the probe 140. Therefore, the trainee can be notified on the spot that the presence position of the stenosis portion X provided in the pseudo sample 20 has been found by notifying by voice or display on the screen of the monitor 130. Thereby, the trainer can efficiently practice the correct operation method of the probe 140 in a situation close to the actual situation, and can improve the ultrasonic diagnostic ability in a short time.

  In addition, by setting the notification method using the voice guide or the screen display guide to be performed step by step, it is possible to recognize stepwise that the pseudo stenosis part X (affected part) is approaching, and training. The guide function can be further enhanced.

  As shown in FIG. 9, the ultrasonic diagnostic training apparatus 30C of the medical ultrasonic diagnostic training system 10C includes an ultrasonic oscillator 40, a pseudo blood tank 50, a pump 60, a flow meter 70, and a backflow prevention in a housing 32. It has a valve 80, a control unit 90, and a concentration adjustment unit 300.

  The concentration adjusting unit 300 adjusts the amount of the viscous substance contained in the simulated blood so that the viscosity of the simulated blood is close to that of the actual blood. For example, in accordance with an instruction from the control unit 90, the mixing ratio of the viscous substance made of fine particles is adjusted to the set value according to the ratio of red blood cells contained in the blood. Therefore, the flow rate or flow rate of the simulated blood flowing in the simulated blood vessel 110 becomes the same as the flow rate or flow rate according to the assumed disease type (for example, hyperlipidemia), and training accuracy is further improved.

  FIG. 10 is a flowchart for explaining the ultrasonic diagnostic training control process 2 of the second embodiment. As shown in FIG. 10, when the power switch is turned on in step S31, the control unit 90 proceeds to step S32 and sets a desired concentration setting value N1 according to the current exercise. In the next step S33, the concentration adjusting unit 300 checks whether or not the simulated blood concentration N is equal to the concentration setting value N1. In step S33, when the simulated blood concentration N is equal to the concentration setting value N1 (in the case of YES), the process proceeds to step S35, and the parameters of the pump driving cycle registered in the memory in advance are read, and according to the current training content Set the pump drive cycle.

  In addition, since step S35-step S44 are the same as the control processing of step S12-step S21 of FIG. 8 mentioned above, description is abbreviate | omitted.

  As described above, in the medical ultrasonic diagnostic training system 10C, the concentration adjustment unit 300 can adjust the pseudo blood concentration N to a desired concentration setting value N1, so that the proportion of red blood cells contained in blood and the content of cholesterol are included. Training can be performed assuming the amount and the training accuracy is further improved. Therefore, the trainer repeats training for finding the position of the stenosis portion X provided in the pseudo specimen 20 in a situation where the concentration N of the pseudo blood is adjusted to a value corresponding to the medical condition, thereby the probe 140. The operation method can be practiced in a situation close to the actual situation, and the ultrasonic diagnostic ability can be further enhanced.
