Description

Technical Field

[0001] The present invention relates to the field of medical detection equipment, in particular to a compression mechanism that releases upon power failure and a breast detection device. Background Art

[0002] When the subject is testing the health of the breast or other muscle tissue, it is generally necessary to place the breast on a placement piece (the upper surface of the testing instrument housing), and then use a compression piece to flatten the breast on the testing instrument. This helps the testing instrument obtain a uniform image of the background. After the test is completed, the compression piece will rise away from the placement piece.

[0003] In the past, an electrically controlled mechanical structure with a travel lock function was used to move the compression and placement parts closer or further apart. However, in the event of a power outage or machine failure, the compression and placement parts would continue to clamp the patient's breast. Due to the high pressure, the patient would be almost unable to break free, which could easily lead to danger. To address this problem, existing electrically controlled mechanical structures, such as motor-driven gear racks, can be released through manual rotation after a power outage. However, these are inconvenient to use, have low durability, and are prone to wear and jamming. Summary of the Invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a compression mechanism and a breast detection device that are released upon power failure, which are easy to use and have improved safety performance.

[0005] The technical solution adopted in the present invention is:

[0006] A compression mechanism that releases when power is off includes: a base frame provided with a placement piece capable of placing objects; a compression piece and a displacement mechanism, wherein the displacement mechanism is arranged on the base frame and connected to the compression piece; an electromagnetic adsorption component and a matching piece, wherein the electromagnetic adsorption component / matching piece is arranged on the compression piece, and correspondingly, the matching piece / electromagnetic adsorption component is arranged on the displacement mechanism or the base frame, and when power is on, the electromagnetic adsorption component can adsorb the matching piece to drive the compression piece toward the placement piece.

[0007] The displacement mechanism includes a hinge mechanism, and the pressing member rotates toward or away from the placing member.

[0008] The compression member includes a compression plate and a compression force arm. A mounting frame is provided on the base frame. The hinge mechanism includes a hinge shaft, which is provided on the mounting frame. One end of the compression force arm is connected to the hinge shaft, and the other end of the compression force arm is connected to the compression plate. The electromagnetic adsorption component is provided on the compression force arm, and the matching member is provided on the mounting frame.

[0009] The electromagnetic adsorption component is an electromagnetic core, and the matching piece is an iron block.

[0010] It also includes a control module, and an external power supply supplies power to the electromagnetic adsorption component through the control module.

[0011] The control module includes a main control unit and a current regulating unit. The external power supply supplies power to the electromagnetic adsorption component through the current regulating unit. The main control module is electrically connected to the control end of the current regulating unit to control the working current of the electromagnetic adsorption component.

[0012] A power-off release compression mechanism according to an embodiment of the present invention has at least the following beneficial effects:

[0013] The compression mechanism of the present invention supplies power to the electromagnetic adsorption component when it is necessary to compress and fix the subject for inspection. After being energized, the electromagnetic adsorption component generates an attractive force on the matching piece, thereby driving the compression piece to approach the placement piece through the displacement mechanism, thereby compressing and restricting the object placed on the compression piece. When a power outage occurs, the electromagnetic adsorption component loses power and the attractive force disappears, so the compression piece can be easily opened. At the same time, the size of the attractive force of the electromagnetic adsorption component on the matching piece can be set. When the subject feels excessive compression, a force greater than the attractive force can be applied to the compression piece, or the compression piece can be opened to prevent excessive compression. This design is simple to operate and improves safety performance.

[0014] A specific embodiment of the present invention also discloses a breast detection device, including an X-ray emitting component, an X-ray receiving component, and a power-off release compression mechanism disclosed in any of the above embodiments, wherein the compression component is light-transmissive, the X-ray emitting component is arranged on a base frame and can emit X-rays toward an object placed on a placement component, and the X-ray receiving component is arranged on the placement component.

[0015] It also includes a lifting drive mechanism, which is arranged on the base frame, and the matching member / electromagnetic adsorption component is arranged on the displacement mechanism. The lifting drive mechanism is connected to the displacement mechanism to be able to drive the pressing member to approach the placement member.

[0016] A breast detection device according to an embodiment of the present invention has at least the following beneficial effects:

[0017] The breast detection device of the present invention utilizes the adsorption effect of the electromagnetic adsorption component and the matching component to enable the compression component to clamp the breast placed on the placement component, and the X-ray emitting component emits X-rays toward the object placed on the placement component. The X-rays pass through the breast and are received by the X-ray receiving component, thereby being used for detection; when a power outage occurs, the attraction disappears, the compression component can be easily opened, and the subject can leave safely. At the same time, the attraction of the electromagnetic adsorption component to the matching component can be set. When the subject feels excessive compression, a force greater than the attraction can be applied to the compression component, or the compression component can be opened to prevent the breast from being excessively compressed. This design is simple to operate, has power-off protection and overvoltage protection functions, and improves safety performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] A compression mechanism that releases when the power is cut off, such as Figure 1As shown, it includes a base frame 1, a pressure piece 2, a displacement mechanism 3, an electromagnetic adsorption component 4 and a matching component 5. The base frame 1 is provided with a placement component 6 for placing objects, the displacement mechanism 3 is arranged on the base frame 1, the displacement mechanism 3 is connected to the pressure piece 2, the electromagnetic adsorption component 4 / matching component 5 is arranged on the pressure piece 2, and correspondingly, the matching component 5 / electromagnetic adsorption component 4 is arranged on the base frame 1 or the displacement mechanism. When power is turned on, the electromagnetic adsorption component 4 can adsorb the matching component 5 to drive the pressure piece 2 toward the placement component 6.

[0025] When the present design is used to compress and fix the subject for testing, power is supplied to the electromagnetic adsorption component 4. After receiving power, the electromagnetic adsorption component 4 generates an attractive force on the matching component 5, thereby driving the compression component 2 to approach the placement component 6 through the displacement mechanism 3, thereby compressing and restricting the object placed on the compression component 2. When a power outage occurs, the electromagnetic adsorption component 4 loses power and the attractive force disappears, and the compression component 2 can be easily opened. At the same time, the attractive force of the electromagnetic adsorption component 4 on the matching component 5 can be set. When the subject feels excessive pressure, a force greater than the attractive force can be applied to the compression component 2, or the compression component 2 can be opened to prevent excessive pressure. The present design is simple to operate and improves safety performance.

[0026] In some embodiments, the displacement mechanism 3 includes a hinge mechanism, and the pressure member 2 rotates closer to or away from the placement member 6. The displacement mechanism 3 can also be a slide rail and slider mechanism, in which a slider is provided on the pressure member 2 and a slide rail is provided on the base frame 1, and the pressure member 2 slides closer to or away from the placement member 6.

[0027] In some embodiments, the compression member 2 includes a compression plate 21 and a compression arm 22. The displacement mechanism may also include a mounting frame 11 and a hinge shaft. The hinge shaft is arranged on the mounting frame 11. One end of the compression arm 22 is connected to the hinge shaft. The other end of the compression arm 22 is connected to the compression plate 21. The electromagnetic adsorption component 4 is arranged on the compression arm 22, and the mating member 5 is arranged on the mounting frame 11.

[0028] The matching piece 5 is arranged below the electromagnetic adsorption component 4 , and the placing piece 6 is arranged below the pressing piece 2 . The electromagnetic adsorption component 4 adsorbs the matching piece, and the pressing piece 2 moves downward to approach the placing piece 6 .

[0029] According to the lever principle, the electromagnetic adsorption component 4 is arranged at one end close to the hinge axis, and the user can flip open the pressing member 2 more easily.

[0030] In some embodiments, the electromagnetic adsorption component 4 is an electromagnetic core, and an electromagnet with an attraction force of 80Kg-120Kg can be used. The matching piece 5 is an iron block, and a galvanized iron plate can be used.

[0031] The compression plate 21 can be made of acrylic, the placement piece 6 can be made of plastic, the compression arm 22 can be made of aluminum alloy, the hinge shaft can be made of stainless steel rod, and the mounting frame 11 can be made of aluminum alloy.

[0032] In some embodiments, a control module is further included, and an external power supply supplies power to the electromagnetic adsorption component through the control module.

[0033] The control module can control the power on and off of the electromagnetic adsorption component, thereby controlling the attraction or opening of the pressing piece. When the external power supply is cut off, the pressing piece will also open due to power failure.

[0034] The control module includes a main control unit and a current regulating unit (not shown in the figure). The external power supply supplies power to the electromagnetic adsorption component through the current regulating unit. The main control module is electrically connected to the control end of the current regulating unit to control the working current of the electromagnetic adsorption component.

[0035] Among them, the main control unit can be an MCU or CPU and its peripheral circuits, and the current regulation unit can adopt a switch tube driving circuit. The main control unit can control the working current of the electromagnetic adsorption component through the current regulation unit, thereby adjusting the attraction between the electromagnetic adsorption component and the matching part.

[0036] A specific embodiment of the present invention also discloses a breast detection device, including an X-ray emitting component 7, an X-ray receiving component 8, and a power-off release compression mechanism disclosed in any of the above embodiments, the compression member 2 is light-transmissive, the X-ray emitting component 7 is arranged on the base frame 1 and can emit X-rays toward an object placed on the placement member 6, and the X-ray receiving component 8 is arranged on the placement member 6.

[0037] The placement member may be a shell of the X-ray receiving assembly 8 , and the X-ray emitting assembly 7 may be fixed above the placement member 6 and the X-ray receiving assembly 8 through the base frame 1 .

[0038] The breast detection device of the present invention utilizes the adsorption effect of the electromagnetic adsorption component and the matching component to enable the compression component to clamp the breast 9 placed on the placement component, and the X-ray emitting component emits X-rays toward the object placed on the placement component. The X-rays pass through the breast 9 and are received by the X-ray receiving component, thereby being used for detection; when a power outage occurs, the attraction disappears, the compression component can be easily opened, and the subject can leave safely. At the same time, the attraction of the electromagnetic adsorption component to the matching component can be set. When the subject feels excessive compression, a force greater than the attraction can be applied to the compression component, or the compression component can be opened to prevent the breast from being excessively compressed. This design is simple to operate, has power-off protection and overvoltage protection functions, and improves safety performance.

[0039] In some embodiments, a lifting drive mechanism (not shown in the drawings) is also included. The lifting drive mechanism is arranged on the base frame 1, and the matching part 5 / electromagnetic adsorption component 4 is arranged on the displacement mechanism 3. The lifting drive mechanism is connected to the displacement mechanism 3 so as to be able to drive the pressing part 2 to approach the placement part 6.

[0040] Among them, such as Figure 1 As shown, the lifting drive mechanism can be composed of a motor, a screw rod and a nut. A guide rail is also provided on the base frame 1. The compression piece can be set on the mounting frame 11. The mounting frame 11 is connected to the nut. The motor drives the screw rod to rotate. The nut can be lifted and lowered on the screw rod, and drives the mounting frame 11 to lift and lower along the guide rail on the base frame 1. The placement piece 6 is located below the mounting frame 11 and the compression piece 2. The electromagnetic adsorption component 4 is provided on the compression piece 2, and the matching piece 5 is provided on the mounting frame 11. The electromagnetic adsorption component 4 and the matching piece 5 are attracted to play a locking role. The compression piece 2 swings down, and at this time the mounting frame 11 moves down. The compression piece 2 can clamp the breast with the placement piece 6. When the motor continues to drive the mounting frame to move down, the force of the breast acting on the compression piece is greater than the attraction of the electromagnetic adsorption component to the matching piece, and the compression piece will be lifted, so that even if the pressure applied by the motor is too large, it will not cause harm to the subject.

[0041] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above preferred embodiments can be freely combined and superimposed.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
