Description

[Technical field]

[0001] The present invention relates to an ultrasonic therapy device for treating a treatment target based on ultrasonic waves, and a fluid circuit set used in the ultrasonic therapy device. This application claims priority to International Patent Application PCT / JP2022 / 017845, filed on April 14, 2022, the contents of which are incorporated herein by reference. [Background technology]

[0002] There is known an ultrasonic therapy device that radiates ultrasonic waves to an affected area of ​​a treatment target such as a patient to perform treatment (see, for example, Patent Documents 1 and 2). The ultrasonic therapy device described in Patent Document 1 includes a robot arm formed by links connected by a plurality of joints, an ultrasonic head unit supported at the tip of the robot arm and having an irradiation unit that irradiates the affected area with ultrasonic waves, and a control device that controls the robot arm and the ultrasonic head unit.

[0003] The tip of the ultrasonic head unit is provided with an ultrasonic generating source that radiates ultrasonic waves to an affected area inside the body of a patient supported on a treatment bed, for example. The ultrasonic head unit described in Patent Document 2 includes, for example, an ultrasonic head unit having a head housing including an ultrasonic generating source, and a flexible contact member formed in a bowl shape so as to cover an opening provided in the head housing through which the wave source is exposed. The contact member is brought into contact with a position on the body surface on an extension line corresponding to the affected area inside the body of the patient. The head housing of the ultrasonic head unit is provided with a mounting part to which the contact member is attached, and a liquid storage part is formed by mounting the contact member to the mounting part so that the tip of the ultrasonic head is filled with a medium liquid that transmits ultrasonic waves. In addition, a flow path member used for supplying a medium liquid to the liquid storage part or for draining the medium liquid is connected to the head housing.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2020-036709 [Patent Document 2] Japanese Patent Application Publication No. 2019-162414 Summary of the Invention [Problem to be solved by the invention]

[0005] It is desirable that the contact member that comes into contact with the patient's body is replaced for each patient in terms of hygiene management. The flow path member connected to supply the intermediate liquid to the liquid storage section covered by the contact member, and the liquid container containing the intermediate liquid connected to the flow path member are replaced for each patient because the ultrasonic transmission performance decreases when air bubbles are mixed into the intermediate liquid. In addition, the intermediate liquid comes into contact with the air remaining in the flow path member as a result of use over time, and the amount of dissolved oxygen gradually increases. As the amount of dissolved oxygen in the intermediate liquid increases, the ultrasonic transmission performance decreases, so it is desirable that the intermediate liquid is also replaced for each patient. In addition, the load on each of the contact members and flow path members varies depending on the treatment situation, and there is a possibility that they may be damaged during treatment if they are used continuously for multiple treatments, so it is desirable that they are replaced for each treatment.

[0006] According to the conventional technology, when performing ultrasonic therapy, it is necessary to manually replace the contact member, the liquid container, and the flow path member, and to manually drain and supply liquid from the liquid storage unit for each patient, which may increase the workload. In addition, it may take time to perform the work of passing water through the liquid storage unit and performing a degassing process in preparation for treatment after replacement.

[0007] The present invention aims to provide an ultrasonic treatment device and a fluid circuit set that can improve the work efficiency of the replacement work when replacing the contact members through which the liquid flows, the flow path members of the fluid circuit section, and the liquid containers for each treatment, as well as the work of supplying and draining the intermediary liquid. [Means for solving the problem]

[0008] One aspect of the present invention is an ultrasonic treatment device comprising: a wave source for irradiating ultrasonic waves so as to focus on a predetermined position inside a treatment target; an ultrasonic head unit having a liquid storage portion formed to be adjustable in volume and including a contact portion whose lower surface side contacts the treatment target; and a fluid circuit portion having a plurality of flow path members through which a mediating liquid that transmits the ultrasonic waves flows and that is filled in the liquid storage portion, the fluid circuit portion comprising: a circuit control device portion for circulating the mediating liquid through the plurality of flow path members; a device mounting portion to which the circuit control device portion is attached at a predetermined position; This ultrasonic therapeutic device comprises an inflow circuit section which causes the intermediary liquid to flow into a liquid storage section, an outflow circuit section which causes the intermediary liquid to flow out of the liquid storage section, and an outflow circuit section which discharges the intermediary liquid to the outside, wherein the equipment mounting section has the circuit control equipment section attached to one side and the multiple flow path members are detachably arranged relative to the circuit control equipment section, and the equipment mounting section has an identification section which comprises an inflow identification section which guides the inflow circuit section, an outflow identification section which guides the outflow circuit section, and an outflow identification section which guides the outflow circuit section. Effect of the Invention

[0009] According to the present invention, it is possible to improve the efficiency of the replacement work when replacing contact members through which liquid flows, flow path members of the fluid circuit section, and liquid containers for each treatment, as well as the work of supplying and draining intermediate liquid.

[0011] 1, the ultrasonic therapy system S includes an ultrasonic therapy device 1 that controls the irradiation of ultrasonic waves, and a management control device 40A that operates the ultrasonic therapy device 1 and manages the usage state. The ultrasonic therapy system S also includes a treatment bed B that supports a patient K who is a treatment target. The ultrasonic therapy device 1 includes a robot arm 2 that supports and moves the target, an ultrasonic head unit 10 provided at the tip of the robot arm 2 as the target, and a housing 20 in which a fluid circuit section 25 (described later) that circulates a medium liquid through the ultrasonic head unit 10 is provided.

[0012] The robot arm 2 has, for example, a plurality of arm members 3-n (n: natural number) rotatably connected around a plurality of joints. In the embodiment shown in FIG. 1, the robot arm 2 has arm members 3-1, 3-2, and 3-3 as the plurality of arm members 3-n. The robot arm 2 is rotatable around a vertical axis and is installed on a floor surface via an arm base 4. The robot arm 2 is configured to be able to move an object to be held to an arbitrary position and hold it in an arbitrary posture. For example, the robot arm 2 holds an ultrasonic head unit 10 while maintaining an upright posture such that the ultrasonic wave emission direction faces a patient K supported on a treatment bed B below the ultrasonic head unit 10.

[0013] The ultrasonic head unit 10 has a cylindrical outer shape, and is held in a position in which the cylindrical central axis TCL is aligned in the up-down direction, for example, by the robot arm 2. The ultrasonic head unit 10 includes a main body 11 having a holder held by the robot arm 2, a contact member 14 that comes into contact with the patient K, and a liquid storage unit 12 to which the contact member 14 is attached and configured so that the storage volume can be adjusted according to the amount of intermediate liquid.

[0014] The ultrasonic head unit 10 is configured to irradiate an affected area of ​​a patient K with ultrasonic waves to perform treatment. The object to be treated based on ultrasonic waves may be not only a human being but also an animal (the object to be treated may be an animal other than a human being). The ultrasonic head unit 10 includes devices for irradiating an affected area inside the object to be treated with focused ultrasonic waves (hereinafter also referred to as High Intensity Focused Ultrasound: HIFU), which are ultrasonic waves for treatment, and diagnostic ultrasonic waves, which are ultrasonic waves different from HIFU. The ultrasonic head unit 10 includes, for example, a wave source 11A (see FIG. 2) on the lower inner side of the main body 11 for irradiating ultrasonic waves inside the object to be treated.

[0015] The wave source 11A includes, for example, a first wave source 11B (see FIG. 2) having a diagnostic probe that projects from the main body 11 into the internal space of the liquid storage section 12 and generates diagnostic ultrasound, and a second wave source 11C (see FIG. 2) that generates HIFU for treatment. The first wave source 11B, for example, irradiates diagnostic ultrasound downward at the tip (tip of the ultrasonic head unit 10) and receives diagnostic ultrasound reflected from an object such as the body of the patient K. The first wave source 11B irradiates diagnostic ultrasound in a predetermined angle range with respect to a central axis TCL along the up-down direction and receives the reflected wave. The first wave source 11B is provided rotatably along the central axis TCL. The first wave source 11B is provided movably in a direction along the central axis TCL. The first wave source 11B is disposed in the internal space of the liquid storage section 12 covered by the contact member 14.

[0016] The second wave source 11C is, for example, configured with a HIFU transducer that generates a plurality of focal points X at equal intervals along a circumference centered on a central axis that coincides with the central axis TCL. The second wave source 11C has an emission surface formed in a dome shape on the lower surface side. The second wave source 11C has, for example, a plurality of ultrasonic transducers (not shown) on the emission surface. The plurality of ultrasonic transducers are arranged so that the envelopes of the plurality of ultrasonic waves to be oscillated are focused at a plurality of focal points. The second wave source 11C is arranged above the first wave source 11B. The second wave source 11C is arranged, for example, rotatably around the central axis L.

[0017] The liquid storage section 12 is configured to be adjustable in storage volume within the liquid storage section 12, for example, by a stretchable cylindrical section 13 made up of two cylindrical bodies and a contact member 14 provided at the lower part of the cylindrical section 13. The internal space of the liquid storage section 12 is filled with a medium liquid that improves the transmission of ultrasonic waves. The contact member 14 is configured to be replaceable as described later.

[0018] The contact member 14 is formed in a bowl shape that bulges downward. One surface side (outer side) of the contact member 14 is a contact portion that comes into contact with the patient K who is the treatment target. The contact portion is a region that includes the lower end portion of the contact member 14. The other surface side (inner side) of the contact portion is formed so as to surround a storage space that stores an intermediate liquid. With the above configuration, the robot arm 2 can position the contact portion of the contact member 14 so as to contact the skin that is located on an extension line of the affected area of ​​the patient K on the treatment bed B, while maintaining the attitude of the ultrasonic head unit 10. A housing 20 is arranged adjacent to the robot arm 2.

[0019] The housing 20 is provided with a fluid circuit section 25 having a plurality of flow paths for circulating the intermediate liquid in the ultrasonic head unit 10 as described later. The fluid circuit section 25 supplies the intermediate liquid to the ultrasonic head unit 10, fills the liquid storage section 12 with the intermediate liquid, and causes the intermediate liquid to flow out of the liquid storage section 12 to circulate the intermediate liquid. The fluid circuit section 25 includes, for example, a pump section 26 (see FIG. 2) for circulating the intermediate liquid in the flow path, a valve section 27 (see FIG. 2) for stopping or releasing the stop of the flow of the intermediate liquid in the flow path, a flow path member Rm (see FIG. 3 described later) for forming the liquid flow path, and a liquid detection section 28 for detecting the liquid flowing in the flow path. The fluid circuit section 25 also includes a pressure detection section 28BB for detecting the pressure of the liquid in the liquid storage section 12. The housing 20 also includes a control device 40 inside.

[0020] 2, the control device 40 is a device that controls the ultrasonic treatment device 1, including the control of the robot arm 2, the control of the ultrasonic head unit 10, and the control of the fluid circuit section 25. The control device 40 is configured, for example, by an information processing terminal device such as a personal computer. The control device 40 is communicatively connected to the ultrasonic treatment device 1. The control device 40 may be directly connected to the ultrasonic treatment device 1, or may be a server connected to a network and communicatively connected to the ultrasonic treatment device 1.

[0021] The control device 40 includes a control unit 42 that controls the ultrasonic treatment device 1. The control device 40 includes a storage unit 46 that stores data required for control, a communication unit 47 that communicates with the ultrasonic treatment device 1, a display unit 48 that displays information required for control, and an input unit 49 that accepts operations required for control.

[0022] The memory unit 46 is a data storage device configured by a storage medium such as a hard disk drive or a flash memory. The memory unit 46 may be built in the control device 40, or may be connected to the outside as an external storage device (may be provided outside the control device 40). The communication unit 47 is a communication interface that transmits and receives control signals between the ultrasonic treatment device 1 and the management control device 40A. The communication unit 47 receives command signals requesting control and detection signals detected from the robot arm 2, the ultrasonic head unit 10, and the fluid circuit unit 25, and transmits control signals for controlling the robot arm 2, the ultrasonic head unit 10, and the fluid circuit unit 25. The communication unit 47 also receives command signals requesting control from the management control device 40A, and transmits detection signals detected by the ultrasonic treatment device 1 and information on the working state of the ultrasonic head unit 10 to the management control device 40A.

[0023] The display unit 48 is configured with a display device such as a liquid crystal display or an organic electro-luminescence (EL) display. The input unit 49 is an information input device such as a keyboard or a touch pad. When the display unit 48 is configured to be touch operable, the input unit 49 may be configured integrally with the display unit 48. The display unit 48 displays a display image including information regarding the control of the ultrasonic treatment device 1. The display unit 48 displays a diagnostic image of the body of the patient K generated based on the detection value detected by the first wave source 11B. The display unit 48 is provided in the ultrasonic head unit 10, and is operated by an operator such as a doctor performing treatment.

[0024] The control unit 42 includes the following multiple control units to individually control the ultrasonic treatment device 1. The control unit 42 includes, for example, a main control unit 42A that performs integrated control of the ultrasonic treatment device 1 based on information input from the input unit 49. The control unit 42 includes, for example, a robot arm control unit 42B that controls the robot arm 2 based on a command input from the input unit 49. The control unit 42 includes, for example, an ultrasonic control unit 42C that controls the ultrasonic head unit 10 based on a command input from the input unit 49. The control unit 42 includes, for example, a liquid supply control unit 42D that controls the fluid circuit unit 25 based on a command input from the input unit 49.

[0025] The main control unit 42A generates a command signal for controlling the ultrasonic treatment device 1 based on, for example, information input from the input unit 49. The main control unit 42A cooperates with each of the control units described below to perform integrated control so that the robot arm 2, ultrasonic head unit 10, and fluid circuit unit 25 configured in the ultrasonic treatment device 1 operate in cooperation with each other. The main control unit 42A is composed of, for example, a central processing unit provided in the control device 40.

[0026] The robot arm control unit 42B controls the drive unit 3A provided in the robot arm 2. The robot arm control unit 42B may be provided on the robot arm 2 side, for example, or may be integrated into the control unit 42 of the control device 40. The robot arm control unit 42B, for example, individually controls a plurality of drive motors provided in a plurality of joints of the robot arm 2. The robot arm control unit 42B acquires a command signal requesting a predetermined operation of the robot arm 2, calculates individual control amounts of the plurality of drive motors based on the contents of the command signal, and generates a control signal. The robot arm control unit 42B acquires data from a detection unit 3B provided in the drive unit 3A, which detects the rotation angle, torque, etc. of each drive motor. The robot arm control unit 42B generates a control signal according to the posture of the plurality of arm members 3-n and the magnitude and direction of the applied acting force based on the data acquired from the detection unit 3B, and controls the robot arm 2.

[0027] The robot arm control unit 42B transmits a control signal to the robot arm 2 via the communication unit 47, and controls the robot arm 2 to perform a predetermined operation. The robot arm control unit 42B acquires data on the drive amount of each joint of the robot arm 2 via the communication unit 47, and controls the operation of the robot arm 2.

[0028] The robot arm control unit 42B controls the robot arm 2 during treatment, for example, to position the tip of the ultrasonic head unit 10 provided on the robot arm 2 at the position of the affected area of ​​the patient K and hold it in a predetermined posture. During treatment preparation before the start of treatment, for example, the robot arm control unit 42B controls the robot arm 2 as described below to hold the ultrasonic head unit 10 in a predetermined first posture so as to make it easy to supply the intermediate liquid to the liquid storage unit 12 of the ultrasonic head unit 10. During treatment preparation after the end of treatment, for example, the robot arm control unit 42B controls the robot arm 2 as described below to hold the ultrasonic head unit 10 in a predetermined second posture so as to make it easy to discharge the intermediate liquid from the liquid storage unit 12 of the ultrasonic head unit 10.

[0029] After the ultrasonic head unit 10 is positioned at a predetermined position during treatment, the ultrasonic control unit 42C controls the ultrasonic head unit 10 based on the acquired command signal to perform a required operation. The ultrasonic control unit 42C may be integrated into the control unit 42 of the control device 40. The main control unit 42A acquires a command signal requesting a predetermined operation from the ultrasonic head unit 10 based on an input operation, calculates individual control amounts of the multiple wave sources based on the contents of the command signal, generates a control signal, and outputs it to the ultrasonic control unit 42C. The ultrasonic control unit 42C transmits the control signal to the ultrasonic head unit 10 via the communication unit 47 to individually control the multiple wave sources. For example, the ultrasonic control unit 42C controls the multiple wave sources to emit ultrasonic waves so that the position of the affected area of ​​the patient K coincides with the multiple focal points X.

[0030] The liquid delivery control unit 42D, as a control device provided in the fluid circuit unit 25 as described below, controls the circuit control device unit 21S including the multiple liquid detection units 28, the multiple pump units 26, and the multiple valve units 27 to circulate the intermediate liquid through the flow path member Rm of the fluid circuit unit 25. The liquid delivery control unit 42D may be integrated into the control unit 42 of the control device 40. The liquid delivery control unit 42D obtains a command signal requesting the circuit control device unit 21S to perform a predetermined operation, calculates individual control amounts of the control devices of the circuit control device unit 21S based on the contents of the command signal, and generates a control signal. The liquid delivery control unit 42D transmits the control signal to the circuit control device unit 21S via the communication unit 47, and controls the circuit control device unit 21S to perform the required operation.

[0031] The liquid sending control unit 42D controls the fluid circuit unit 25 during treatment to adjust the amount of the intermediate liquid stored in the liquid storage unit 12. By adjusting the amount of the intermediate liquid stored in the liquid storage unit 12, the amount of the intermediate liquid is adjusted to an appropriate amount for transmitting ultrasonic waves from the second wave source 11C that generates HIFU for treatment. When the ultrasonic head unit 10 is held in a predetermined first position during treatment preparation before the start of treatment, the liquid sending control unit 42D controls the fluid circuit unit 25 to supply new intermediate liquid to the fluid circuit unit 25 and the liquid storage unit 12. When the ultrasonic head unit 10 is held in a predetermined second position during treatment preparation after the end of treatment, the liquid sending control unit 42D controls the fluid circuit unit 25 to discharge the intermediate liquid from the liquid storage unit 12 and the fluid circuit unit 25. With the above configuration, the control device 40 can operate the ultrasonic treatment device 1 in an integrated manner based on the input operation contents.

[0032] 3 shows a schematic configuration of the fluid circuit section 25. The fluid circuit section 25 includes, for example, a plurality of flow path members Rm (m: natural number) through which the intermediate liquid flows, a circuit control device section 21S that causes the intermediate liquid to flow through the plurality of flow path members Rm, and a liquid container 29 that contains the intermediate liquid. The fluid circuit section 25 also includes a device attachment section 21 to which the circuit control device section 21S is attached at a predetermined position. The device attachment section 21 will be described later. The flow path member Rm is configured to be replaceable for each diagnosis of the patient K. The flow path member Rm is formed, for example, in a tubular shape from a flexible resin material. The flow path member Rm is formed, for example, from a polyethylene tube. In the embodiment shown in FIG. 3, the fluid circuit section 25 includes flow path members R1, R2, R3, R4, and R5 as the plurality of flow path members Rm.

[0033] The fluid circuit section 25 includes, for example, a first circuit section 25A that circulates the intermediate liquid through the multiple flow path members Rm, and a second circuit section 25B that communicates with the outside air and allows gas (air) to flow from the outside into the first circuit section 25A. The first circuit section 25A includes, for example, an inflow circuit section 25A1 that allows the intermediate liquid to flow into the liquid storage section 12, an outflow circuit section 25A2 that allows the intermediate liquid to flow out of the liquid storage section 12, and an outflow circuit section 25A3 that discharges the intermediate liquid to the outside.

[0034] The first circuit section 25A has, for example, a flow path member R1 that connects the liquid container 29 and the liquid storage section 12 (contact member 14 in FIG. 3). The liquid storage section 12 (contact member 14 in FIG. 3) is provided with an inflow connection section 14RA through which the intermediate liquid flows in, and an outflow connection section 14RB through which the intermediate liquid flows out. The end R1B of the flow path member R1 is detachably fitted into the inflow connection section 14RA. The inflow connection section 14RA is formed of, for example, a tubular member made of an elastically deformable resin material and has a diameter larger than that of the flow path member R1. The inner diameter of the inflow connection section 14RA is formed to be slightly smaller than the outer diameter of the flow path member R1.

[0035] When the flow path member R1 is fitted, the inflow connection portion 14RA is elastically deformed to fit closely around the end R1B of the flow path member R1, thereby maintaining airtightness. The start end R2A of the flow path member R2 is fitted into the outflow connection portion 14RB. The outflow connection portion 14RB is formed of, for example, a tubular member made of an elastically deformable resin material and having a diameter larger than that of the flow path member R2. The inner diameter of the outflow connection portion 14RB is formed to be slightly smaller than the outer diameter of the flow path member R2. When the flow path member R2 is fitted, the outflow connection portion 14RB is elastically deformed to fit closely around the start end R2A of the flow path member R2, thereby maintaining airtightness. With the above configuration, the connection work of the flow path members R1 and R2 at the inflow connection portion 14RA and the outflow connection portion 14RB can be performed manually without the need for tools. For example, a luer lock connector can be used to connect the flow path members R1 and R2 at the inflow connection portion 14RA and the outflow connection portion 14RB. The contact member 14 and the flow path members R1, R2 can be integrated by being connected to each other via the inflow connection portion 14RA and the outflow connection portion 14RB.

[0036] The outflow circuit section 25A2 has, for example, a flow path member R2 that connects the liquid storage section 12 and the liquid container 29, and a flow path member R3 that bypasses the flow path member R2. The discharge circuit section 25A3 has, for example, a flow path member R4 that is connected to the outflow circuit section 25A2 and has a downstream side that is open to the outside. A tank T that contains, for example, an intermediate liquid is provided on the downstream side of the flow path member R4. The second circuit section 25B has a flow path member R5 that branches off from the downstream side of the flow path member R2.

[0037] The circuit control device section 21S (see Figs. 6 and 7 described later) is configured to include, for example, a pump section 26, a valve section 27, and a liquid detection section 28 as control devices. The pump section 26 includes, for example, a liquid supply pump 26A provided in the middle of the flow path member R1, and a liquid drainage pump 26B provided in the middle of the flow path member R2. The liquid supply pump 26A supplies the medium liquid to the liquid storage section 12 in the inflow circuit section 25A1. The liquid drainage pump 26B discharges the medium liquid from the liquid storage section 12 in the outflow circuit section 25A2.

[0038] The valve section 27 includes a plurality of electromagnetic valves (pinch valves) 27A to 27F. The liquid detection section 28 includes a concentration meter 28A provided in the flow path member R1 and detecting the dissolved oxygen concentration in the intermediate liquid, a pressure sensor 28B included in a pressure detection section 28BB provided in the flow path member R2 and detecting the pressure in the flow path member Rm, and a plurality of liquid detection sensors 28C provided in the flow path member Rm near the electromagnetic valves 27A to 27F, respectively, and detecting the presence or absence of the intermediate liquid flowing through the flow path member Rm. The control unit 42 is configured so that the device mounting portion 21 is replaceable and so that the stopped states of all the electromagnetic valves 27A to 27F can be released.

[0039] The concentration meter 28A is provided between the liquid supply pump 26A and the liquid storage section 12, and detects the dissolved oxygen concentration in the intermediate liquid supplied to the liquid storage section 12, thereby monitoring the intermediate liquid required for transmitting ultrasound from the second wave source 11C that generates the therapeutic HIFU.

[0040] The pressure detection unit 28BB is provided between the drainage pump 26B and the liquid storage unit 12, and monitors the liquid pressure of the intermediate liquid flowing through the flow path member R2. The pressure sensor 28B monitors the pressure of the flowing intermediate liquid by detecting the air pressure of a gas reservoir formed inside the pressure detection unit 28BB, and monitors the liquid pressure inside the liquid storage unit 12. The control unit 42 (liquid delivery control unit 42D) adjusts (including stops) the amount of liquid supplied into the liquid storage unit 12 by controlling the fluid circuit unit 25 based on the air pressure of the gas reservoir detected by the pressure sensor 28B, for example. Adjusting the amount of liquid supplied into the liquid storage unit 12 prevents the contact member 14 from bursting due to expansion.

[0041] Furthermore, the pressure sensor 28B may detect the pressure inside the flow path member R2 to monitor the presence or absence of liquid and the amount of liquid inside the liquid storage section 12. The control section 42 (ultrasonic control section 42C) may, for example, control the second wave source 11C that generates HIFU for treatment based on the pressure inside the flow path member R2 detected by the pressure sensor 28B, determine whether or not HIFU irradiation is possible, and control operations related to starting or stopping HIFU irradiation. The detection of the presence or absence of liquid inside the liquid storage section 12 is not limited to a pressure sensor, and may, for example, be a sensor that can detect that the liquid storage section 12 is filled with liquid and the amount of water required for HIFU irradiation, or a water amount detection unit using a sensor that can detect the amount of water may be configured.

[0042] As shown in FIG. 4, the electromagnetic valves 27A to 27F are composed of, for example, a clamp portion 27K that clamps the flow path member Rm, and a solenoid actuator 27S provided in the clamp portion 27K. The flow path member Rm is attached to the clamp portion 27K as a flow path holding portion RH. In the clamp portion 27K, the flow path member Rm is clamped detachably at the clamping position of the clamp portion 27K. The clamp portion 27K opens outward at the side surface of the housing 20, and the flow path member Rm is configured to be detachable from the clamping position of the clamp portion 27K through the opening of the clamp portion 27K. The solenoid actuator 27S includes an electromagnetic coil 27S1 and a plunger 27S2 that slides relative to the electromagnetic coil 27S1 (see FIG. 4(A)). When the electromagnetic coil 27S1 is energized, the plunger 27S2 moves in a direction that protrudes toward the inside of the clamp portion 27K (see FIG. 4(B)). At this time, the plunger 27S2 cooperates with the clamp portion 27K to crush the flow path member Rm, thereby stopping the flow of the intermediate liquid flowing through the flow path member Rm.

[0043] Returning to FIG. 3, the electromagnetic valve 27A is provided, for example, in a downstream portion of the liquid supply pump 26A in the flow path member R1. The electromagnetic valve 27A starts or stops the flow of the intermediate liquid in the flow path member R1 (stops the flow or releases the stop). The electromagnetic valve 27B is provided, for example, in the flow path member R2, downstream of the liquid storage section 12. The electromagnetic valve 27B starts or stops the flow of the intermediate liquid in the flow path member R2. The electromagnetic valve 27C is provided, for example, in a portion of the flow path member R2 that is parallel to the flow path member R3. The electromagnetic valve 27C starts or stops the flow of the intermediate liquid when filling or discharging the intermediate liquid in the flow path member R2.

[0044] The electromagnetic valve 27D is provided, for example, on the upstream side of the liquid container 29 in the downstream portion of the flow path member R2. The electromagnetic valve 27D is provided, for example, on the flow path member R4 when circulating and filling the intermediate liquid in the flow path member R2. The electromagnetic valve 27E is provided, for example, on the flow path member R4. The electromagnetic valve 27E starts or stops the flow of the intermediate liquid when it is discharged from the flow path member R4. The electromagnetic valve 27F is provided, for example, on the flow path member R5. The electromagnetic valve 27F starts or stops the flow of air when it flows from the flow path member R5 into the inside of the first circuit portion 25A.

[0045] As shown in FIG. 5, the liquid supply pump 26A is configured, for example, by a tube pump that continuously deforms the cross-sectional shape of the flow path member R1 from one side to the other in the flow direction to pump the intermediate liquid therein. The liquid supply pump 26A includes a rotating roller 26A1 and a housing 26A2 that rotatably supports the rotating roller 26A1. The liquid supply pump 26A includes the rotating roller 26A1 and the housing 26A2 as a flow path holding part RJ to which the flow path member Rm is attached, and the flow path member Rm is attached between the rotating roller 26A1 and the housing 26A2. The rotating roller 26A1 is configured such that an end of the rotating roller 26A1 can move in a radial direction from the rotation center of the rotating roller 26A1. The end of the rotating roller 26A1 is also provided with a biasing member (not shown) that applies a predetermined biasing force in a direction away from the rotation center. A gap is provided between the housing 26A2 and the end of the rotating roller 26A1 by moving the end of the rotating roller 26A1 toward the center of rotation against the biasing force of the biasing member. The flow path member R1 is fitted into the gap. The flow path member R1 is sandwiched between the inner wall of the housing 26A2 and the end of the rotating roller 26A1, and is crushed and deformed, and is attached to the flow path holding part RJ.

[0046] In the liquid supply pump 26A, when the rotating roller 26A1 is rotated, the end of the rotating roller 26A1 moves while squashing the flow path member R1 in the rotation direction, and the medium liquid inside the flow path member R1 is pumped downstream in the rotation direction. After the rotating roller 26A1 moves, the squashed flow path member R1 returns to its original shape due to the restoring force of the flow path member itself, and at that time, the medium liquid flows in from the upstream side of the flow path member R1. The drainage pump 26B is also configured as a tube pump like the liquid supply pump 26A.

[0047] For example, a part of the flow path member R1 is detachably fitted in a curved state in the supply pump 26A. For example, a part of the flow path member R3 is detachably fitted in a curved state in the drain pump 26B. With the above configuration, the flow path members R1 and R3 in the supply pump 26A and the drain pump 26B can be attached and detached manually without using tools.

[0048] Returning to FIG. 3, liquid container 29 is formed into a bag from a resin material such as polyethylene or polypropylene. Liquid container 29 is formed by welding the peripheries of two sheets of resin material. An upper portion of liquid container 29 is provided with a bonding portion 29A in which two sheets of resin material are bonded together over a predetermined width. An upper portion of bonding portion 29A is provided with an engagement portion 29B formed by a through hole. A hook-shaped support member 24 of a support portion 23 provided on housing 20 as described below engages with engagement portion 29B, and liquid container 29 is held in a suspended state.

[0049] The liquid container 29 is filled with an intermediate liquid without any air bubbles. The intermediate liquid is degassed water from which dissolved gas has been removed in order to improve ultrasonic conductivity. In this embodiment, the degassed water used as the intermediate liquid is degassed water in which the dissolved gas value (dissolved oxygen concentration value) is a predetermined value (3 ppm) or less. The liquid container 29 is prepared with the intermediate liquid contained therein, and is connected to the fluid circuit unit 25 so that the intermediate liquid can be supplied to the fluid circuit unit 25. Liquid container 29 is provided with a connection part 29C for connection to fluid circuit part 25. Connection part 29C includes a first connection part 29D connected to inflow circuit part 25A1 for supplying the intermediate liquid, and a second connection part 29E connected to outflow circuit part 25A2 for returning the intermediate liquid from liquid storage part 12 (contact member 14 in FIG. 3) to liquid container 29. First connection part 29D is provided, for example, hanging down from the lower part of liquid container 29.

[0050] The start end R1A of the flow path member R1 is detachably fitted into the first connection part 29D. The first connection part 29D is formed of, for example, a tubular member made of an elastically deformable resin material and having a diameter larger than that of the flow path member R1. The inner diameter of the first connection part 29D is formed to be slightly smaller than the outer diameter of the flow path member R1. When the flow path member R1 is fitted into the first connection part 29D, the first connection part 29D elastically deforms and comes into close contact with the periphery of the start end R1A of the flow path member R1, thereby maintaining airtightness. A luer lock connector, which is a general medical component, may be used as the first connection part 29D.

[0051] The second connection part 29E is provided, for example, protruding in the horizontal direction at the top of the liquid container 29. The end R2B of the flow path member R2 is detachably fitted into the second connection part 29E. The second connection part 29E is formed, for example, of a tubular member made of an elastically deformable resin material and having a diameter larger than that of the flow path member R2. The inner diameter of the second connection part 29E is formed to be slightly smaller than the outer diameter of the flow path member R2. When the flow path member R2 is fitted, the second connection part 29E elastically deforms and comes into close contact with the periphery of the end R2B of the flow path member R2, thereby maintaining airtightness. A luer lock connector may be used as the second connection part 29E as a general medical member. The intermediate liquid unit 29UT is configured by including the liquid container 29, the connection portion 29C, and the engagement portion 29B. With the above configuration, the connection work of the liquid container 29 to the flow path members R1, R2 can be performed manually without the need for tools. Then, the liquid container 29 and the flow path members R1, R2 can be integrated by connecting them via the connection portion 29C.

[0052] 6, the housing 20 is provided with an equipment mounting section 21 to which the fluid circuit section 25 is attached such that one side faces the outside. The equipment mounting section 21 is provided, for example, on one side of the housing 20, with flow path holders RH and RJ (described later) arranged side by side. The equipment mounting section 21 is rotatably supported by a rotation support section 22 provided along one side of the housing 20 in the up-down direction. The equipment mounting section 21 is provided in the form of a door that can be opened and closed freely relative to the housing main body 20A.

[0053] A rod-shaped support section 23 that supports liquid container 29 is provided on the upper surface of housing 20. A hook-shaped support member 24 that engages with an engagement section 29B provided on liquid container 29 is provided on the upper part of support section 23. Liquid container 29 is suspended from support section 23 by engaging engagement section 29B with support member 24.

[0054] As shown in FIG. 7, the device mounting portion 21 is provided with a part of the fluid circuit portion 25. The device mounting portion 21 includes a first mounting portion 21A. The first mounting portion 21A includes a circuit control device portion 21S. The circuit control device portion 21S is used to control the flow of the intermediate liquid flowing through the multiple flow path members Rm. The device mounting portion 21 also includes a second mounting portion 21B to which the multiple flow path members Rm are attached. On one surface side of the device mounting portion 21 facing outward, a control device of the circuit control device portion 21S that causes the intermediate liquid to flow through the multiple flow path members Rm is attached. On one surface side of the device mounting portion 21, a liquid supply pump 26A, a liquid discharge pump 26B, multiple electromagnetic valves 27A to 27F, and multiple liquid detection sensors 28C are attached at predetermined positions as control devices constituting the circuit control device portion 21S. As a result, the one surface side of the device mounting portion 21 constitutes the first mounting portion 21A.

[0055] A second mounting portion 21B is detachably provided on one surface side of the device mounting portion 21 in correspondence with the first mounting portion 21A. A circuit control device section 21S is disposed on the outwardly facing one surface side of the first mounting portion 21A. By disposing the control devices of the circuit control device section 21S, flow path holding portions RH, RJ that hold the respective flow path members Rm are disposed (see Figs. 4 and 5). A plurality of flow path support portions 21M are disposed on the outwardly facing one surface side of the second mounting portion 21B. A flow path member Rm is attached to each of the plurality of flow path support portions 21M.

[0056] The second mounting portion 21B includes, for example, a detachable mounting member 21P formed in a plate shape and a plurality of flow path members Rm provided on the detachable mounting member 21P. The plurality of flow path members Rm are arranged in advance at predetermined positions on one surface side facing outward of the detachable mounting member 21P. The plurality of flow path members Rm are attached to the predetermined positions based on a predetermined arrangement relationship. Before the detachable mounting member 21P is attached to the first mounting portion 21A (before the start end R1A of the flow path member R1 and the end end R2B of the flow path member R2 are connected to the liquid container 29), the plurality of flow path members Rm are attached to the detachable mounting member 21P in a state in which the start end R1A of the flow path member R1 and the end end R2B of the flow path member R2 are open. The start end R1A of the flow path member R1 and the end end R2B of the flow path member R2 are connected to the liquid container 29 when the liquid container 29 is attached to the support portion 23 (see FIG. 3).

[0057] Before the detachable mounting member 21P is attached to the first mounting portion 21A (before the terminal end R1B of the flow path member R1 and the starting end R2A of the flow path member R2 are connected to the liquid storage portion 12), the multiple flow path members Rm are attached to the detachable mounting member 21P in a state in which the terminal end R1B of the flow path member R1 and the starting end R2A of the flow path member R2 are open. The terminal end R1B of the flow path member R1 and the starting end R2A of the flow path member R2 are connected to the liquid storage portion 12. In this embodiment, they are connected to the contact member 14. The multiple flow path members Rm are positioned and attached to the detachable mounting member 21P in a state in which they are exposed at multiple predetermined positions. The multiple predetermined positions are, for example, positions corresponding to the positions of the control devices included in the circuit control device unit 21S provided in the device mounting portion 21. For example, at least some of the multiple flow path supports 21M are disposed at positions upstream and downstream of the position of the control device included in the circuit control device section 21S in the flow direction in which the intermediate liquid flows through the flow path member Rm.

[0058] The second mounting portion 21B is provided so as to be detachable from the first mounting portion 21A. A plurality of flow path members Rm are arranged on the second mounting portion 21B. The plurality of flow path members Rm are arranged corresponding to the positions of the circuit control device unit 21S arranged on the first mounting portion 21A. On one surface side of the device mounting portion 21, a detachable engagement portion 21K is provided for positioning and engaging the detachable mounting member 21P at a predetermined position with respect to the first mounting portion 21A.

[0059] The detachable engagement portion 21K is formed, for example, by one or more hook members 21F. A pair of hook members 21F are attached to the upper part of one surface side of the device mounting portion 21. A pair of mounting engagement portions 21Q, which engage with the hooks of the pair of hook members 21F, is formed on the detachable mounting member 21P. The mounting engagement portion 21Q is formed as a through hole. The pair of mounting engagement portions 21Q is formed, for example, corresponding to the positions of the hooks of the pair of hook members 21F. The through hole formed as the mounting engagement portion 21Q is formed at the upper end of the detachable mounting member 21P. The mounting engagement portion 21Q is formed as a vertically long rectangular opening so that the upper end can be hooked onto the hook of the hook member 21F after the hook penetrates through the mounting engagement portion 21Q.

[0060] This allows the second mounting portion 21B to be accurately positioned and mounted on the first mounting portion 21A. As a result, the control device of the circuit control device unit 21S arranged on the first mounting portion 21A and the multiple flow path members Rm provided on the second mounting portion 21B can be aligned in a corresponding manner. At this time, the second mounting portion 21B can be manually mounted on the first mounting portion 21A without using any tools. When the second mounting portion 21B is mounted, the multiple exposed flow path members Rm are attached to the control device of the circuit control device unit 21S. The detachable mounting member 21P is provided with a cutout portion 21Ro (o: natural number) formed by cutting out a part of the plate-shaped detachable mounting member 21P by a predetermined size. The cutout portion 21Ro is formed at a position corresponding to the position of the control device of the circuit control device unit 21S as necessary. In this embodiment, multiple cutout portions 21Ro (21R1 to 21R9) are formed.

[0061] In the detachable mounting member 21P, the plurality of flow path members Rm are positioned and attached in an exposed state in the plurality of cutout portions 21Ro while maintaining a predetermined piping posture at a predetermined position. The first cutout portion 21R1 is provided, for example, at a position of the detachable mounting member 21P corresponding to the position of the drainage pump 26B. The first cutout portion 21R1 is formed in a size and shape such that it does not come into contact with the drainage pump 26B when the detachable mounting member 21P is attached to or detached from the device mounting portion 21. The flow path member R3 is attached in a state exposed from the first cutout portion 21R1.

[0062] The flow path member R3 is exposed in a loop shape at the first cutout portion 21R1 so that it matches the mounting position of the housing of the drainage pump 26B and can be easily attached and detached when the detachable mounting member 21P is attached to and detached from one side of the device mounting portion 21. The second cutout portion 21R2 is provided at a position of the detachable mounting member 21P corresponding to the positions of the electromagnetic valve 27C and one of the multiple liquid detection sensors 28C, and parts of the flow path member R2 and the flow path member R3 are exposed. The third cutout portion 21R3 is provided at a position of the detachable mounting member 21P corresponding to the position of the liquid detection sensor 28C arranged downstream of the electromagnetic valve 27E, and part of the flow path member R4 is exposed and the end R4E of the flow path member R4 is open.

[0063] The fourth cutout portion 21R4 is provided at a position of the detachable mounting member 21P corresponding to the positions of the electromagnetic valve 27F and the liquid detection sensor 28C, and a part of the flow path member R5 is exposed. The fifth cutout portion 21R5 is provided at a position of the detachable mounting member 21P corresponding to the positions of the liquid detection sensor 28C, and a part of the flow path member R1 is exposed. The sixth cutout portion 21R6 is provided at a position of the detachable mounting member 21P corresponding to the positions of the electromagnetic valve 27A and the liquid detection sensor 28C, and a part of the flow path member R1 is exposed. The seventh cutout portion 21R7 is provided at a position of the detachable mounting member 21P corresponding to the positions of the supply pump 26A and the liquid detection sensor 28C, and a part of the flow path member R1 is exposed in a loop shape. The eighth cutout portion 21R8 is provided at a position of the detachable mounting member 21P corresponding to the position of the electromagnetic valve 27B, and a part of the flow path member R2 is exposed. The ninth cutout portion 21R9 is provided at a position of the detachable mounting member 21P corresponding to the positions of the electromagnetic valve 27D, the liquid detection sensor 28C, and the electromagnetic valve 27E, and a part of the flow path member R2 is exposed.

[0064] With the above configuration, when the second mounting portion 21B is mounted to the first mounting portion 21A, the exposed flow path members Rm are attached so as to be held by the corresponding control devices of the circuit control device unit 21S via the cutout portions 21Ro formed as necessary. The circuit control device unit 21S constitutes a plurality of flow path holding portions RH, RJ provided on the first mounting portion 21A and each holding a plurality of flow path members Rm.

[0065] With the above-mentioned configuration, the exposed multiple flow path members Rm can be manually attached and detached via the multiple cutout portions 21Ro to the respective flow path holding portions RH, RJ provided in the pump portion 26, the valve portion 27, and the liquid detection portion 28, which are control devices constituting the circuit control equipment portion 21S.

[0066] As shown in FIG. 8, the contact member 14 provided in the liquid storage section 12 is formed in a bowl shape that bulges downward (toward the patient). The contact member 14 is made of a material that is biocompatible and has an acoustic impedance similar to that of a living body. The contact member 14 is made of a flexible material such as silicone rubber. The liquid storage section 12 side, which is the opposite side of the contact member 14 to the patient side, is filled with a medium liquid. The contact member 14 is formed so as to be replaceable for each treatment. The contact member 14 has a contact part 14A that contacts the body of the patient K on the lower surface side, which is the patient side of the contact member 14. The contact part 14A is formed in a circular tray shape. A cylindrical attachment part 14B is formed around the contact part 14A, the lower part of which is continuous with the contact part 14A and extends so as to surround the upper part of the periphery of the contact part 14A. The attachment part 14B is formed, for example, in a truncated cone shape whose diameter increases as it goes upward. The mounting portion 14B is mounted to a mounting target portion (not shown) of the ultrasonic head unit 10. A flange portion 14C that engages with the mounting target portion is formed on the upper end of the mounting portion 14B. The flange portion 14C is formed in an annular shape that protrudes outward in the horizontal direction.

[0067] A part of the internal space is formed inside the liquid storage section 12 by, for example, the contact section 14A and the mounting section 14B. The internal space is filled with a medium liquid. An inflow connection section 14RA that is connected to the inflow circuit section 25A1 is provided at a first position of the mounting section 14B.

[0068] The inflow connection part 14RA is connected to the flow path member R1 and allows the intermediate liquid to flow into the contact member 14. The inflow connection part 14RA is composed of a tubular part 14Q, one end of which is connected to the mounting part 14B, and a connection member 14P provided on the other end of the tubular part 14Q. The end R1B of the flow path member R1 is fitted into the connection member 14P. The outflow connection part 14RB, which is connected to the inflow circuit part 25A1, is provided at a second position different from the first position of the mounting part 14B in a plan view. The second position is, for example, a position that is 90 degrees out of phase with the first position, centered on the center 14CL of the contact part 14A in a plan view. The outflow connection part 14RB is connected to the flow path member R2 and allows the intermediate liquid to flow out of the contact member 14.

[0069] The outflow connection portion 14RB includes a tubular portion 14Q having one end connected to the mounting portion 14B, and a connection member 14P provided on the other end of the tubular portion 14Q. The start end R2A of the flow path member R2 is fitted into the connection member 14P.

[0070] With the above configuration, the inflow connection part 14RA and the outflow connection part 14RB can be connected to the flow path members R1 and R2 manually without using tools. As the connection member 14P, for example, a luer lock connector that is generally used as a medical device member is used. In addition, the position of the mounting part 14B where the inflow connection part 14RA and the outflow connection part 14RB are provided is preferably close to the flange part 14C.

[0071] After the installation of the plurality of flow path members Rm of the fluid circuit section 25 is completed, the control section 42 controls the liquid supply pump 26A and the electromagnetic valves 27A to 27F to supply the intermediate liquid to the flow path members Rm and to the liquid storage section 12.

[0072] When removing the multiple flow path members Rm of the fluid circuit section 25 (specifically, before removing them), the control section 42 controls the liquid supply pump 26A, the liquid drainage pump 26B, and the electromagnetic valves 27A-27F to drain the medium liquid from the flow path members Rm and from the liquid storage section 12. When preparing for treatment, the control section 42 controls the robot arm 2 to maintain the ultrasonic head unit 10 in a supply position or a drainage position so as to easily supply or drain the medium liquid to or from the liquid storage section 12.

[0073] In the replacement work of attaching the flow path member Rm of the fluid circuit section 25, the control section 42 controls the robot arm 2 to move the ultrasonic head unit 10 to a replacement work position that is a predetermined position with respect to the fluid circuit section 25, and adjusts the attitude of the liquid storage section 12 so that the intermediate liquid can be easily supplied to the liquid storage section 12. In the replacement work of removing the flow path member Rm of the fluid circuit section 25, the control section 42 controls the robot arm 2 to move the ultrasonic head unit 10 to a replacement work position that is a predetermined position with respect to the fluid circuit section 25, and adjusts the attitude of the liquid storage section 12 so that the intermediate liquid can be easily discharged to the liquid storage section 12. For example, a position around the fluid circuit section 25 is set as the replacement work position. A specific replacement work position is set to an upper position spaced apart from the upper surface of the housing 20 on which the fluid circuit section 25 is provided.

[0074] As shown in FIG. 9, in a liquid supply step in preparation for treatment, the control unit 42 controls the robot arm 2 to hold the ultrasonic head unit 10 in a first position. The first position is, for example, a position in which the outflow connection part 14RB is on the upper side compared to the inflow connection part 14RA so that air in the liquid storage part 12 can be easily released. In this embodiment, the contact part 14A of the contact member 14 (liquid storage part 12) faces downward. The first position is preferably a position in which the outflow connection part 14RB is at the top in the liquid storage part 12. With the ultrasonic head unit 10 held in the first position, the control unit 42 controls the circuit control device part 21S of the fluid circuit part 25 to supply the intermediate liquid to the contact member 14 (liquid storage part 12).

[0075] As shown in FIG. 10, in the drainage step in preparation for treatment, the control unit 42 controls the robot arm 2 to hold the ultrasonic head unit 10 in the second position. The second position is, for example, a position in which the outflow connection part 14RB is lower than the inflow connection part 14RA so that the intermediate liquid in the liquid storage part 12 can be easily drained. In this embodiment, the contact part 14A of the contact member 14 (liquid storage part 12) is in a position facing upward, so that the contact member 14 after drainage can be efficiently and easily replaced. The second position is preferably a position in which the outflow connection part 14RB is at the bottom in the liquid storage part 12. The control unit 42 controls the circuit control device part 21S of the fluid circuit part 25 while holding the ultrasonic head unit 10 in the second position to drain the intermediate liquid from the contact member 14 (liquid storage part 12).

[0076] FIG. 11 shows a flow chart of the process executed in the fluid supply step in preparation for treatment. The operator inputs an operation to start mounting the flow path member Rm of the fluid circuit section 25 through the input section 49 of the control device 40. Based on the input command signal to start replacement, the control section 42 controls the robot arm 2 to move the ultrasonic head unit 10 to a position suitable for replacement work. The control section 42 opens all the electromagnetic valves 27A to 27F (step S100). The operator sets the contact member 14 to the cylindrical section 13, sets the liquid container 29 to the support section 23 of the housing 20, sets the second mounting section 21B, on which the multiple flow path members Rm are provided, to the first mounting section 21A, and attaches the multiple flow path members Rm to the control device of the circuit control device section 21S. At this time, the operator connects the multiple flow path members Rm to the liquid container 29 and the liquid storage section 12 (contact member 14) (step S102).

[0077] The control unit 42 closes the electromagnetic valve 27D provided on the downstream side of the flow path member R2 and the electromagnetic valve 27F provided on the flow path member R5 (step S104). As a result, the intermediate liquid flows through the flow path members R1 to R3, and then is discharged from the flow path member R4. In response to an input from the input unit 49 of the control device 40, the control unit 42 controls the robot arm 2 to hold the ultrasonic head unit 10 in the first position and operates the liquid supply pump 26A (step S106). The control unit 42 monitors whether the liquid detection sensor 28C provided on the flow path member R4 is turned on (step S108), and continues step S106 if the liquid detection sensor 28C is turned off. If the liquid detection sensor 28C provided on the flow path member R4 is turned on, the control unit 42 operates the drainage pump 26B (step S110). When the intermediate liquid flows through the flow path member R4, the intermediate liquid flows through the flow path members R1 to R3 of the inflow circuit portion 25A1 and the outflow circuit portion 25A2. Therefore, when the liquid detection sensor 28C provided on the flow path member R4 is turned on, the control unit 42 operates the drainage pump 26B to flow the intermediate liquid downstream of the flow path member R2.

[0078] The control unit 42 closes the electromagnetic valve 27C provided in the flow path member Rm (step S112). After step S112, the control unit 42 operates the drainage pump 26B for a predetermined time, for example, 3 seconds (step S114). Before the predetermined time has elapsed, the process returns to step S110, and when the predetermined time has elapsed, the drainage pump 26B is stopped (step S116). This allows air to be bled downstream of the flow path member R2. The control unit 42 opens the electromagnetic valve 27C provided in the flow path member R2 parallel to the flow path member R3 and the electromagnetic valve 27D provided downstream of the flow path member R2, and closes the electromagnetic valve 27E provided in the flow path member R4 (step S118).

[0079] The control unit 42 continues to operate the liquid supply pump 26A to circulate the intermediate liquid through the flow path member Rm and the liquid container 29 (step S120). At this time, the operator checks whether there are any air bubbles inside the flow path member Rm and the liquid storage unit 12, and if there are any air bubbles attached to the inner surface, the operator strikes the flow path member Rm and the contact member 14 to apply vibrations and remove the air bubbles. The control unit 42 controls the robot arm 2 to return the ultrasonic head unit 10 to the normal position (liquid supply completion position) (step S122). The control unit 42 stops the liquid supply pump 26A and stops all the corresponding circuit control device units 21S (step S124). Each of the above steps is automatically performed by the control unit 42, and may be stopped or started as appropriate based on an operation input from the input unit 49.

[0080] 12 shows a flow chart of the process executed in the drainage step in preparation for treatment. The operator inputs an operation to start removing the flow path member Rm of the fluid circuit unit 25 from the input unit 49 of the control device 40. Based on the input command signal to start replacement, the control unit 42 controls the robot arm 2 to move the ultrasonic head unit 10 to a position suitable for the replacement work. The control unit 42 controls the robot arm 2 to hold the ultrasonic head unit 10 in the second attitude (step S200). The control unit 42 opens the electromagnetic valve 27A provided on the upstream side of the liquid storage unit 12, the electromagnetic valve 27B provided on the downstream side of the liquid storage unit 12, the electromagnetic valve 27E provided on the flow path member R4 for drainage, and the electromagnetic valve 27F provided on the flow path member R5 for opening to the atmosphere (step S202).

[0081] The control unit 42 operates the liquid supply pump 26A and the liquid discharge pump 26B (step S204). The control unit 42 confirms that the liquid detection sensor 28C provided in the liquid discharge flow path member R4 is in an ON state and liquid is being discharged from the flow path member R4 (step S206). The control unit 42 determines whether the liquid detection sensor 28C provided in the liquid discharge flow path member R4 is in an OFF state for a predetermined time, for example, several seconds (step S208). If the liquid detection sensor 28C is in an OFF state in step S208, the process returns to step S206. If the liquid detection sensor 28C is in an ON state in step S208, the control unit 42 stops the liquid supply pump 26A and the liquid discharge pump 26B (step S210). The control unit 42 opens all the electromagnetic valves 27A to 27F (step S212).

[0082] The control unit 42 controls the robot arm 2 to hold the ultrasonic head unit 10 in a normal position (step S214). The control unit 42 displays an image on the display unit 48 to prompt the user to replace the flow path member Rm of the fluid circuit unit 25, the contact member 14, and the liquid container 29. An image notifying the user that the removal is complete is displayed on the display unit 48. The worker removes the flow path member Rm of the fluid circuit unit 25 and the liquid container 29 together with the contact member 14 and the second attachment unit 21B (step S216). The worker attaches new contact member 14, flow path member Rm of the fluid circuit unit 25 together with the second attachment unit 21B, and the liquid container 29 to complete the replacement (step S217). The worker performs an input operation on the input unit 49 to indicate that the removal or replacement is complete. The control unit 42 closes all the electromagnetic valves 27A to 27F based on the input operation (step S218). Each of the above steps is automatically performed by the control unit 42, but may be stopped or started as appropriate based on operations input from the input unit 49 during intermediate steps.

[0083] 13 is a flowchart showing the processing operations executed when increasing the amount of liquid in the liquid storage section 12 after the contact member 14, the liquid container 29, and the flow path member Rm of the fluid circuit section 25 are set and the inside is filled with the intermediate liquid. The operator inputs an operation to increase the amount of the intermediate liquid in the liquid storage section 12 through the input section 49. The control section 42 opens the electromagnetic valve 27A provided upstream of the liquid storage section 12 (step S300). The control section 42 operates the liquid supply pump 26A based on the operation input through the input section 49 (step S302).

[0084] The operator visually checks the amount of liquid in the liquid storage section 12 and determines whether the amount is appropriate or not (step S304). If the operator determines that the amount of liquid is appropriate, the operator performs an operation to input information indicating that the amount of liquid is appropriate via the input section 49. The control section 42 stops the liquid supply pump 26A based on the operation input to the input section 49 (step S306). The control section 42 closes the electromagnetic valve 27A provided upstream of the liquid storage section 12 (step S308). The amount of liquid in the liquid storage section 12 can be increased based on the above steps.

[0085] 14 shows a flow chart of the processing operations executed when reducing the amount of liquid in the liquid storage section 12 after the contact member 14, the liquid container 29, and the flow path member Rm of the fluid circuit section 25 are set and filled with the intermediate liquid. The operator inputs an operation to reduce the amount of the intermediate liquid in the liquid storage section 12 through the input section 49. The control section 42 opens the electromagnetic valve 27B provided downstream of the liquid storage section 12 and the electromagnetic valve 27D provided downstream of the flow path member R2 (step S400). The control section 42 operates the drainage pump 26B based on the operation input through the input section 49 (step S402). The operator visually checks the amount of liquid in the liquid storage section 12 and judges whether the amount of liquid is appropriate or not (step S404).

[0086] When the operator determines that the amount of liquid is appropriate, the operator performs an operation to input information indicating that the amount of liquid is appropriate through input unit 49. The amount of liquid may be automatically detected using a sensor or the like. Based on the operation input through input unit 49, control unit 42 stops drainage pump 26B (step S406). Control unit 42 closes electromagnetic valve 27B provided downstream of liquid storage unit 12 and electromagnetic valve 27D provided downstream of flow path member R2 (step S408). Based on each of the above steps, the amount of liquid in liquid storage unit 12 can be reduced.

[0087] The above-mentioned replaceable parts such as the fluid circuit section 25 may be configured as a unit in a distribution form. For example, the device mounting section 21, the fluid circuit section 25, and the liquid supply control section 42D may be configured as a fluid operating device. The device mounting section 21 may be attached to an object other than the housing 20. That is, the fluid circuit section 25, which is a component of the fluid operating device, is connected to the ultrasonic head unit 10 including the wave source 11A that irradiates ultrasonic waves so as to focus on a predetermined position inside the treatment object, and the liquid storage section 12 that includes the contact section 14A whose lower surface side contacts the treatment object and is formed so as to be adjustable in volume, and has a plurality of flow path members Rm through which the intermediate liquid that is filled in the liquid storage section 12 and transmits ultrasonic waves flows.

[0088] The contact member 14 and the liquid container 29 can be integrated by connecting them to the flow path member Rm that forms the liquid flow path of the fluid circuit section 25 via a connecting member. The integrated contact member 14, liquid container 29, and flow path member Rm can be removed together for each patient to be treated or for each treatment, and replaced with a new contact member 14, liquid container 29, and flow path member Rm. In addition, the new contact member 14 and the new liquid container 29 can be easily replaced by being connected in advance to the new flow path member Rm that forms the liquid flow path of the fluid circuit section 25 and prepared in an integrated state. Note that the contact member 14 and the liquid container 29 are structured to be integrated by connecting them to the flow path member Rm via the connecting member 14P, but the contact member 14 and the liquid container 29 may be directly connected to the flow path member Rm without the connecting member 14P to form an integrated structure.

[0089] The fluid circuit section 25 includes a first circuit section 25A that circulates the intermediate liquid through the multiple flow path members Rm, and a second circuit section 25B that causes gas to flow into the first circuit section 25A.

The second mounting section 21B includes a removable mounting member 21P to which a plurality of flow path members Rm are attached. The removable mounting member 21P is formed with an attachment engagement section 21Q that engages with the removable engagement section 21K. The removable mounting member 21P is attached with a plurality of flow path members Rm at a plurality of predetermined positions by a plurality of flow path support sections 21M. At the plurality of predetermined positions, a notch section 21Ro is formed as necessary at a position corresponding to the position of the control device of the circuit control device section 21S. The flow path member Rm is exposed and arranged from the notch section 21Ro.

[0092] The liquid supply control unit 42D, which is a component of the fluid operating device, controls the fluid circuit unit 25 to adjust the amount of intermediate liquid stored in the liquid storage unit 12, as well as to discharge the intermediate liquid from the fluid circuit unit 25 and supply new intermediate liquid to the fluid circuit unit 25. The liquid supply control unit 42D may perform individual authentication of the fluid circuit unit 25 between the fluid circuit unit 25 and the control device 40 and may perform communication to diagnose the operation of the circuit control device unit 21S. The liquid supply control unit 42D may be provided on the control device 40 side.

[0093] Furthermore, among the above-mentioned configurations of the fluid circuit section 25, a fluid circuit set in which the replacement object is packaged may be configured. FIG. 15 shows a fluid circuit set CS in which the replacement object is packaged. The fluid circuit set CS is accommodated in the container CT in a state in which a plurality of flow path members Rm are attached in advance to the detachable mounting member 21P at a position corresponding to the circuit control device section 21S provided in the first mounting section 21A and constitute a part of the circuit of the fluid circuit section 25. The fluid circuit set CS is connected to an ultrasonic head unit 10 including a wave source 11A that irradiates ultrasonic waves so as to focus on a predetermined position inside the treatment object, and a liquid storage section 12 that includes a contact section 14A whose lower surface side contacts the treatment object and is formed so as to be adjustable in volume, and includes a plurality of flow path members Rm through which a medium liquid that is filled in the liquid storage section 12 and transmits ultrasonic waves flows.

[0094] The fluid circuit set CS includes a detachable mounting member 21P to which a plurality of flow path members Rm are attached. The plurality of flow path members Rm are attached to the detachable mounting member 21P by a plurality of flow path support parts 21M, with the plurality of flow path members Rm positioned at a plurality of predetermined positions. At the plurality of predetermined positions, a notch portion 21Ro is formed as necessary at positions corresponding to the positions of the control devices of the circuit control device part 21S. In this embodiment, a plurality of notch portions 21Ro are formed because a notch portion 21Ro corresponding to a plurality of control devices is required. A plurality of flow path members Rm are arranged exposed from the plurality of notch portions 21Ro.

[0095] The fluid circuit set CS is accommodated in a container CT capable of accommodating the detachable mounting member 21P with the multiple flow path members Rm attached thereto. The contact member 14 may also be accommodated in the container CT. The container CT is, for example, configured of a box body and a packaging member. The box body is a container formed of a recyclable material such as paper used in the distribution process. The packaging member is a cushioning material filled between the object to be accommodated in the box body and the inner wall of the box body. The packaging member may be a member having an internal space formed with the shape of the object to be accommodated, or may be a material in which a large number of cushioning materials formed with the same shape are filled between the object to be accommodated and the box body. The fluid circuit set CS may also be accommodated in a bag-shaped packaging body and then accommodated in the container CT.

[0096] The fluid circuit set CS may also include a contact member 14 attached to the ultrasonic head unit 10. The contact member 14 is formed to include a contact portion 14A provided at the lower portion, and a mounting portion 14B formed to extend so as to surround the upper portion of the periphery of the contact portion 14A and to be mounted on the mounting target portion of the ultrasonic head unit 10. The mounting portion 14B includes an inflow connection portion 14RA connected to an inflow circuit portion 25A1 of the fluid circuit portion 25 that causes the medium liquid to flow into the liquid storage portion 12 at the first position, and an outflow connection portion 14RB connected to an outflow circuit portion 25A2 of the fluid circuit portion 25 that is provided at a second position different from the first position in a plan view and causes the medium liquid to flow out of the liquid storage portion 12. The contact member 14 may also be housed in a bag-shaped package and then housed in the container CT.

[0097] The fluid circuit set CS may also include a medium fluid unit 29UT that contains a medium fluid. The medium fluid unit 29UT may include a liquid container 29 that contains the medium fluid, and a connection part 29R that connects the liquid container 29 and the fluid circuit part 25. The liquid container 29 has a storage space that contains the medium fluid. The connection part 29R is connected to the fluid circuit part 25 that has a plurality of flow path members Rm through which the medium fluid flows. The liquid container 29 is provided with an engagement part 29B that engages with the support part 23. The connection part 29R includes a first connection part 29D that is connected to the liquid container 29, and a second connection part 29E that is connected to the liquid container 29. The connection part 29R also includes an inflow connection part 29RA to which the inflow circuit part 25A1 is connected, and an outflow connection part 29RB that is connected to the outflow circuit part 25A2. The liquid container 29 is prepared in a state in which unused medium fluid is contained, and therefore includes an outflow restriction member 29S that prevents the outflow of the medium fluid from the liquid container 29. Outflow restriction members 29S are provided between liquid container 29 and inflow connection portion 29RA, and between liquid container 29 and outflow connection portion 29RB, and clamps are used which are commonly used as medical devices for restriction and flow rate adjustment. Inflow connection portion 29RA and outflow connection portion 29RB are connection members, and luer lock connectors are used as commonly used medical devices. The intermediate liquid contained in liquid container 29 is deaerated water from which dissolved gas has been removed. Liquid container 29 may be contained in container CT. Liquid container 29 may also be contained in a bag-shaped packaging body, which is then contained in container CT.

[0098] In addition, the above-mentioned fluid circuit set CS may be housed in the housing CT in a state where the contact member 14 and the liquid container 29 are connected in advance to a plurality of flow path members Rm attached to the detachable mounting member 21P and integrated together.

[0099] As described above, the ultrasonic treatment device 1 can maintain the performance of the intermediate liquid for each treatment by replacing the flow path member Rm of the fluid circuit unit 25, the contact member 14, and the liquid container 29 containing new intermediate liquid (deaerated water) for each treatment of the patient K. According to the ultrasonic treatment device 1, the replacement work of the flow path member Rm, the contact member 14, and the liquid container 29 of the fluid circuit unit 25 is configured to be a simple work such as connecting and removing the multiple flow path members Rm, so that the workload can be reduced. According to the ultrasonic treatment device 1, the multiple flow path members Rm of the fluid circuit unit 25 are unitized in a state in which some of the flow paths of the fluid circuit unit 25 are formed in advance, so that the multiple flow path members Rm can be reliably attached to the position corresponding to the position of the circuit control device unit 21S provided on the device attachment unit 21. According to the ultrasonic treatment device 1, the multiple flow path members Rm in which the intermediate liquid flows and accumulates, the contact member 14, and the liquid container 29 containing new intermediate liquid (deaerated water) are replaced for each treatment, so that appropriate sanitary management can be performed.

[0100] The components of the control unit 42 described above, including the main control unit 42A, the robot arm control unit 42B, the ultrasound control unit 42C, and the liquid delivery control unit 42D, are realized by, for example, a hardware processor such as a CPU (Central Processing Unit) executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by cooperation between software and hardware. The program may be stored in a storage device (storage device having a non-transient storage medium) such as an HDD (Hard Disk Drive) or a flash memory in advance, or may be stored in a removable storage medium (non-transient storage medium) such as a DVD or a CD-ROM, and may be installed in the storage device by mounting the storage medium in a drive device. The processing executed in the control unit 42 may be performed by a computer on a server by cloud computing. The processing executed in the control unit 42 may be performed by distributing functions among multiple distributed computers.

[0101] The above-mentioned fluid circuit section 25 is configured such that the second circuit section 25B, which causes gas to flow into the first circuit section 25A, is connected to the outflow circuit section 25A2, through which liquid flows from the liquid storage section 12 (contact member 14 in Figure 3) to the liquid container 29, but the second circuit section 25B may also be connected to the inflow circuit section 25A1, through which liquid flows from the liquid container 29 to the liquid storage section 12.

[0102] As shown in FIG. 16, the fluid circuit section 25 is provided with a second circuit section 25B for introducing gas into the first circuit section 25A by connecting a flow path member R5 of the second circuit section 25B to the middle of the flow path member R1 of the inflow circuit section 25A1 through which the liquid flows from the liquid container 29 to the liquid storage section 12 (contact member 14 in FIG. 16). Specifically, the second circuit section 25B is provided by connecting the flow path member R5 to the first connection section 29D side of the liquid container 29 in the middle of the flow path member R1 between the liquid container 29 and the liquid supply pump 26A. The second circuit section 25B is connected to the middle of the flow path member R1 of the first circuit section 25A between the liquid container 29 and the liquid supply pump 26A to open the inside of the flow path member Rm that forms the flow path of the liquid container 29, the liquid storage section 12, and the fluid circuit section 25 to the atmosphere, thereby preventing the inside from becoming negative pressure due to the outflow of liquid, and allowing the liquid to be smoothly discharged from the inside. The second circuit portion 25B through which gas flows in is connected to the outflow circuit portion 25A2 through which liquid flows to the liquid container 29 as shown in FIG. 3, and it is also possible to provide two second circuit portions 25B by further adding a second circuit portion 25B to the inflow circuit portion 25A1 through which liquid flows from the liquid container 29 to the liquid storage portion 12 as shown in FIG. 16.

[0103] (Variation 1) Modifications of the housing 20 according to the present invention will be described below. 17, the housing 200 in this modification has a plurality of flow path support parts 21M arranged on the upper surface of the housing main body 20B. That is, the housing 200 in this modification further includes a plurality of flow path support parts 21M together with the support part 23 on the upper surface. The flow path support 21M disposed on the upper surface of the housing body 20B is configured to be capable of mounting a plurality of flow path members Rm. As a result, the plurality of flow path members Rm are positioned and mounted at a plurality of predetermined positions on the upper surface of the housing body 20B by the plurality of flow path support parts 21M.

[0104] FIG. 18 shows a housing 200 and an ultrasonic head unit 10 in this modified example. In a liquid supply step in preparation for treatment and a liquid drainage step in preparation for treatment, the ultrasonic head unit 10 moves to a predetermined position (liquid supply position) shown in Fig. 18. In addition, when replacing the contact member 14 (liquid storage section 12), the liquid container 29, and the flow path member Rm, the ultrasonic head unit 10 moves to a predetermined position shown in Fig. 18. The predetermined position of the ultrasonic head unit 10 shown in FIG. 18 is a position where the ultrasonic head unit 10 is located at least above the upper surface of the housing 200 (housing main body 20B). The specified position of the ultrasonic head unit 10 shown in FIG. 18 is preferably a position where the ultrasonic head unit 10 is located above an area surrounded by a plurality of flow path support members 21M arranged on the upper surface of the housing main body 20B and overlaps with that area when viewed in the vertical direction. That is, the projection area on the upper surface of the housing 200 (housing main body 20B) that coincides with a predetermined position (water supply position) of the ultrasonic head unit 10 when viewed in the vertical direction is surrounded by multiple flow path support parts 21M arranged on the upper surface of the housing 200 (housing main body 20B).

[0105] With this configuration, in this modified example, during the liquid supply process in preparation for treatment, the liquid drainage process in preparation for treatment, and when replacing the contact member 14 (liquid storage section 12), the liquid container 29, and the flow path member Rm, the ultrasonic head unit 10 can be moved above the housing 200 to perform the work. This allows liquid to be supplied to and drained from the contact member 14 (liquid storage section 12) in close proximity to other members provided in the housing main body 20B, shortening the worker's movement path and allowing liquid to be supplied and drained more efficiently. In addition, since the contact member 14 (liquid storage portion 12), the liquid container 29 and the flow path member Rm can be replaced while being brought close to each other, replacement can be performed more efficiently.

[0106] (Variation 2) Modifications of the device mounting portion 21 according to the present invention will be described below. 19, the device mounting part 210 according to this modification includes a plurality of identification portions 220-223 on a first mounting part 211 and a second mounting part 212 (detachable mounting member 213). The plurality of identification portions 220-223 further include arrow portions 224, 225, and 226, and an identification character portion 227.

[0107] The indicators 220 to 223 are guides that indicate the predetermined positions at which the flow path members Rm are to be disposed. The indicators 220 to 223 are shown in different colors (colored in different colors). The indicator 220 (outflow indicator) is shown by a solid line in Fig. 19, for example, in blue. The indicator 220 indicates a predetermined position where the flow path members R2 and R3 are arranged. The indicator 220 guides the outflow circuit portion 25A2. The indicator 220 includes an indicator 220A provided on the first attachment portion 211 and an indicator 220B provided on the second attachment portion 212. The distinguishable portion 221 (second circuit portion distinguishable portion) is shown by a hollow line in FIG. 19, for example, in yellow. The distinguishable portion 221 indicates a predetermined position where the flow path member R5 is disposed. The distinguishable portion 221 guides the second circuit portion. The distinguishable portion 221 includes a distinguishable portion 221A provided on the first attachment portion 211 and a distinguishable portion 221B provided on the second attachment portion 212. The identifier 222 (inflow identifier) ​​is shown by a dashed line in Fig. 19, for example, in red. The identifier 222 indicates a predetermined position where the flow path member R1 is disposed. The identifier 222 guides the inflow circuit portion 25A1. The identifier 222 includes an identifier 222A provided on the first attachment portion 211 and an identifier 222B provided on the second attachment portion 212. The identifier 223 (discharge identifier) ​​is shown by a dashed line in Fig. 19, for example, in green. The identifier 223 indicates a predetermined position where the flow path member R4 is disposed. The identifier 223 guides the discharge circuit section 25A3. The identifier 223 includes an identifier 223A provided on the first attachment section 211 and an identifier 223B provided on the second attachment section 212.

[0108] Additionally, the identifiers 220, 222, and 223 include arrow portions 224, 225, and 226, respectively. The arrow portions 224 to 226 indicate the flow direction of the medium liquid flowing through the flow path members Rm arranged in the identifiers 220, 222, and 223. The arrow portions 224 to 226 are indicated in different colors (colored in different colors). The indicator 220 has an arrow portion 224. The arrow portion 224 is shown in blue, for example. The arrow portion 224 has an arrow portion 224A provided on the first attachment portion 211 and an arrow portion 224B provided on the second attachment portion 212. The identification portion 222 includes an arrow portion 225. The arrow portion 225 is shown in red, for example. The arrow portion 225 includes an arrow portion 225A provided on the first attachment portion 211 and an arrow portion 225B provided on the second attachment portion 212. The identification portion 223 includes an arrow portion 226. The arrow portion 226 is shown in green, for example. The arrow portion 226 includes an arrow portion 226A provided on the first attachment portion 211 and an arrow portion 226B provided on the second attachment portion 212.

[0109] The identification character portion 227 is provided on the first attachment portion 211. The identification character portion 227 indicates the components (the pump portion 26, the valve portion 27, and the liquid detection portion 28) provided in the vicinity of the position where the identification character portion 227 is provided. In the example of FIG. 19, the identification character portion 227 indicates that the liquid supply pump 26A is provided in the vicinity of the position where the identification character portion 227 is provided.

[0110] With this configuration, in this modified example, an operator can use the identification portions 220-223 as guides to mount the flow path member Rm on the equipment mounting portion 210. Furthermore, by referring to the arrow portions 224-226, the operator can mount the flow path member Rm on the equipment mounting portion 21 while accurately grasping the flow direction of the medium liquid in the flow path member Rm. Furthermore, if an abnormality occurs in the equipment, the operator can easily identify the equipment in which the abnormality has occurred by referring to the identification character portion 227. Therefore, the operator can more efficiently perform the installation work of the flow path member Rm, and the installation location can be prevented from being mistaken. Also, the operator can easily identify the device in which an abnormality has occurred, thereby improving the maintainability of the device mounting portion 210.

[0111] In the configuration of the above modified example, the flow path members Rm arranged in the identifiers 220 to 223 may be shown in the same color as the identifiers 220 to 223 (or may be colored in a different color). In other words, the flow path members arranged in each identifier may be shown in a different color (or may be colored in a different color). Flow path members R2 and R3 arranged in identifier 220 (outflow identifier) ​​may be shown in blue, for example. The flow path member R5 arranged in the distinguishing portion 221 (second circuit portion distinguishing portion) may be shown in yellow, for example. The flow path member R1 disposed in the identifier 222 (inflow identifier) ​​may be shown in red, for example. The flow path member R4 disposed in the indicator 223 (discharge indicator) may be shown in green, for example.

[0112] It should be noted that the operator does not necessarily need to place the entire flow path member Rm accurately on the recognition portions 220-223, and a part of the flow path member Rm may be placed near the recognition portions 220-223. Some or all of the indicators 220 to 223 do not have to be color-coded.
