Description

Technical Field

[0001] The utility model relates to the technical field of shock wave lithotripsy, in particular to a shock wave lithotripsy with automatic pressure coupling. Background Art

[0002] With the increasing maturity of the application of shock wave technology, extracorporeal shock wave lithotripsy has become the preferred option for treating urinary stones in the human body due to its characteristics of less trauma, short treatment time and few side effects.

[0003] During the extracorporeal shock wave therapy, the degree of coupling between human skin and the shock wave generator water bag will greatly affect the effect of lithotripsy. Therefore, the operator of the lithotripsy machine needs to pay attention to the degree of coupling between the shock wave generator water bag and human skin when performing shock wave lithotripsy. At this time, it is necessary to use the hand to feel the coupling pressure between the water bag and human skin to prevent the lithotripsy effect from being affected by poor coupling between the shock wave generator water bag and human skin during the treatment process.

[0004] Currently, lithotripsy machines on the market rely on the lithotripsy operator to manually feel the contact surface between the water bag and human skin to ensure the coupling degree between the shock wave generator water bag and human skin. When the treatment area is in a private part of the human body, feeling the coupling degree by touch will inevitably cause embarrassment to the operator and the patient.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a shock wave lithotripsy with automatic pressure coupling is proposed. Utility Model Content

[0006] The utility model aims to provide a shock wave lithotripsy with automatic pressure coupling to solve the problems raised in the above background technology.

[0008] Preferably, a heat dissipation window is provided on the side of the crusher housing, a dust shielding plate is fixedly connected to the inner wall of the heat dissipation window, a water inlet is fixedly connected to the side of the crusher housing deviating from the heat dissipation window, a sealing plug is embedded in the water inlet, a transparent plate is fixedly connected to the back of the water tank, a scale is provided on the surface of the transparent plate, a control screen is fixedly connected to the surface of the main unit, a dust shielding plate rotatably connected to the main unit is provided on the top of the control screen, and a magnetic plate fixedly connected to the top of the main unit is attached to the back of the dust shielding plate.

[0009] Preferably, a conversion circuit is provided inside the crusher housing to convert the mains input electrical energy into high-voltage electrical energy output, and the high-voltage cable transmits the high-voltage electrical energy.

[0010] Preferably, the water pump and the solenoid valve can control the wave source water bag to couple to perform drainage and flushing states.

[0011] Preferably, diamond-shaped through holes are provided on the surface of the dust-shielding plate.

[0012] Preferably, the transparent plate is in the shape of a vertical strip, and the scales are arranged at equal intervals vertically.

[0013] Preferably, the sealing plug forms a closed structure of the water inlet.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By setting up the solenoid valve, the host converts the AC input electrical energy into high-voltage electrical energy output through the internal conversion circuit. The high-voltage electrical energy is released to the shock wave source device through the high-voltage cable, so that the shock wave source device generates a shock wave. The shock wave passes through the wave source water bag coupling into the human body, and then crushes the stones. The sensor detects the pressure in the wave source and transmits the pressure data to the host through the data cable. The host calculates the current coupling pressure between the wave source water bag coupling and the human skin, automatically controls the operation of the water pump and the solenoid valve, and fills or drains the wave source to adjust the water fullness in the wave source.

[0016] By setting a clamp ring, in order to prevent the high-voltage cable from bending during use, the clamp ring can be used to limit it. It is only necessary to align the two sets of clamp rings with the high-voltage cable and rotate the threaded rod to drive the two sets of sliders to approach each other, thereby driving the clamp ring to clamp and fix the high-voltage cable to achieve the purpose of bundling. With the help of the transparent plate and the ruler, medical staff can see how much water is left in the water tank, and the water inlet is sealed with a sealing plug to prevent the water from being contaminated by dust. When the equipment is not in use, the dust shield can be flipped down to cover the control screen to achieve the purpose of dust prevention. BRIEF DESCRIPTION OF THE DRAWINGS
