Description

Technical Field

[0001] This utility model relates to the field of biomedical instruments, specifically a feeding structure for a magnetically shielded cardiac magnetic device bed. Background Technology

[0002] The bed frame of the magnetically shielded magnetocardiogram (MCC) device is a crucial component. It guides the subject into the testing environment and assists the MCC device in locating the heart. The MCC device can accurately detect the heart's magnetic field, which is only a fraction of the size of the Earth's magnetic field, even in the complex electromagnetic environment of a medical setting. It enables safe, non-invasive, and accurate multi-dimensional functional imaging of the cardiovascular system in a short time. However, when using a magnetocardiogram (MCC), the device must first be placed directly above and close to the heart; only with appropriate spacing can high-quality data be obtained. Therefore, a bed feed structure capable of accurate positioning is needed to assist the MCC device in its localization.

[0003] In existing technologies, the bed of the magnetically shielded magnetocardiogram (MCC) device can only perform one horizontal feed movement, merely to help move the subject into the testing environment, and cannot effectively assist the testing equipment in accurate positioning. This results in low data quality from the MCC testing equipment. Furthermore, the existing bed movement utilizes synchronous belt drive, which has low precision and a certain backlash. It performs poorly when high-precision reverse movement is required. Additionally, the synchronous belt has a short lifespan and is prone to failure due to wear, aging, or fatigue, resulting in low transmission efficiency. It may also loosen during operation, requiring periodic tensioning to maintain transmission efficiency, increasing maintenance costs and workload.

[0004] Therefore, those skilled in the art have provided a bed feeding structure for a magnetically shielded cardiomagnetic device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a feeding structure for a magnetically shielded cardioid device bed to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A magnetically shielded magnetic core device bed feed structure includes a bed bottom assembly, a bed board support assembly, and a bed board assembly. The bed bottom assembly includes a bed bottom plate, a first photoelectric sensor, a second photoelectric sensor, a slider, a sensor baffle, a stop block, a bed bottom motor, a reducer, a clutch, a ball screw, a screw nut seat, and a slide rail. The bed board assembly includes a bed board, a bed board motor, a coupling assembly, a linear module, an adapter block, and rollers.

[0008] Two slide rails are provided and fixed to the upper sides of the bed base plate with screws. The first photoelectric sensor and the second photoelectric sensor are installed on the bed base plate at the two ends of one side of the slide rail with screws. The bed base motor is installed between the slide rails above the bed base plate with screws. The reducer is located at the output shaft of the bed base motor, and the ball screw is located at the output shaft of the reducer. The input shaft of the reducer is connected to the bed base motor through a coupling. The ball screw is connected to the output shaft of the reducer through a clutch. The slider is slidably located above the slide rail, and the two ends of the slide rail are provided with stops that are screwed to the bed base plate. The screw nut seat is threaded to the outer periphery of the ball screw.

[0009] The bed board motor is fixed on one side of the middle of the bed board. The linear module is set on one side of the output shaft of the bed board motor. The linear module and the bed board motor are connected by a coupling assembly. The adapter block is set on one side of the linear module and is connected to the base plate of the magnetocardiogram detection module by screws.

[0010] When the subject is tested, he / she first lies on the bed board. The magnetic cardiometacardiogram (MCC) detection module is moved to the top of the subject's chest cavity by a motor. Then, the probe lifting module is lowered to a position 5 mm away from the subject's chest cavity. After the position of the MCC detection module is determined, the motor at the bottom of the bed is operated to send the subject into the magnetic shielding barrel for testing and data collection.

[0011] As a further embodiment of this utility model: the bed frame base plate in the bed frame support assembly is mounted on the lead screw nut seat and the slider with screws, which can share the weight and guide the bed frame assembly to move. The bed frame assembly is set above the bed frame support assembly. The sensor baffle is mounted on the side wall of the bed frame support in the bed frame support assembly with screws. When the bed frame assembly delivers the subject to the designated position, the sensor baffle triggers the photoelectric sensor detection signal, cuts off the power to the bed bottom motor, and stops the bed movement. At this time, the bed reaches the magnetic shielding space and begins to collect signals. After the magnetocardiogram detection module is positioned, the lead screw of the bottom assembly of the bed frame is used for transmission to send the bed frame assembly and the magnetocardiogram detection module into the magnetic shielding barrel for data collection.

[0012] As a further improvement of this invention: the magnetocardiogram (MCG) detection module includes a base plate and a probe lifting module. The base plate and the linear module are connected by screws, allowing the MCG detection module to move together. A roller assembly is located above the other end of the bed board, with rollers rolling on it. The adapter block is connected to the base plate by screws, which can share the load of the linear module, providing guidance and increasing its service life while reducing maintenance costs. The bed board motor transmits power to the linear module via a coupling assembly. When the MCG detection module moves to the designated position, the bed board motor stops, and the probe lifting module is then manually lowered to the appropriate position, at which point the MCG detection module is positioned. This design allows for more precise positioning of the MCG detection module.

[0013] As a further improvement of this utility model: the magnetocardiogram measuring device is equipped with an internal guide rail, and the rollers contact the internal guide rail to support the bed during the movement of the bed, which can reduce the friction of linear motion and make the bed run more smoothly.

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

[0015] 1. This utility model has a roller assembly at one end of the bed body near the bucket opening, which contacts the guide rail inside the bucket to support the bed body and reduce linear friction, making the bed body run more smoothly.

[0016] 2. This utility model has a linear module under the bed board to assist in positioning and help the magnetocardiogram detection equipment to perform secondary positioning, so as to achieve more accurate positioning of the subject.

[0017] 3. In this utility model, the bed body is moved by a lead screw to send the test subject into the magnetic shielding barrel. It has high positioning accuracy, low maintenance requirements, and long service life. Attached Figure Description

Detailed Implementation

[0024] Please see Figures 1-5 A magnetic shielded core magnet device bed feeding structure includes a bed bottom assembly 100, a bed board support assembly 200, and a bed board assembly 300. The bed bottom assembly 100 includes a bed bottom plate, a first photoelectric sensor 101, a second photoelectric sensor 102, a slider 103, a sensor baffle 104, a stop block 105, a bed bottom motor 106, a reducer 107, a clutch 108, a ball screw 109, a screw nut seat 110, and a slide rail 111. The bed board assembly 300 includes a bed board 301, a bed board 301 motor, a coupling assembly 303, a linear module 304, an adapter block 305, and a roller 306.

[0025] Two slide rails 111 are provided and fixed to the upper sides of the bed base plate with screws. The first photoelectric sensor 101 and the second photoelectric sensor 102 are installed on the bed base plate at the two ends of one side of the slide rail 111 with screws. The bed base motor 106 is installed between the slide rails 111 above the bed base plate with screws. The reducer 107 is located at the output shaft of the bed base motor 106. The ball screw 109 is located at the output shaft of the reducer 107. The input shaft of the reducer 107 is connected to the bed base motor 106 through a coupling. The ball screw 109 is connected and driven to the output shaft of the reducer 107 through a clutch 108. The slider 103 is slidably located above the slide rail 111, and the two ends of the slide rail 111 are provided with stops 105 that are screwed to the bed base plate. The screw nut seat 110 is threaded to the periphery of the ball screw 109.

[0026] The motor of the bed board 301 is fixed on one side of the middle part of the bed board 301. The linear module 304 is set on one side of the output shaft of the motor of the bed board 301, and the linear module 304 and the motor of the bed board 301 are connected by a coupling assembly 303. The adapter block 305 is set on one side of the linear module 304, and the adapter block 305 is connected to the base plate of the magnetocardiogram detection module 400 by screws.

[0027] When the subject is tested, he / she first lies on the bed board 301. The magnetic heart detection module 400 is driven by a motor to move to the top of the subject's chest cavity. Then the probe lifting module 402 is lowered to a position 5 mm away from the subject's chest cavity. After the position of the magnetic heart detection module 400 is determined, the motor at the bottom of the bed is operated to send the subject into the magnetic shielding barrel for testing and data collection.

[0028] In the bed board 301 support assembly 200, the bed frame base plate 201 is installed above the lead screw nut seat 110 and the slider 103 by screws. It can share the weight and guide the bed board 301 assembly 300 to move. The bed board 301 assembly 300 is set above the bed frame support assembly. The sensor baffle 104 is installed on the side wall of the bed frame support in the bed board 301 support assembly 200 by screws. When the bed frame assembly delivers the subject to the designated position, the sensor baffle 104 triggers the photoelectric sensor detection signal, cuts off the power to the bed bottom motor 106, and stops the bed movement. At this time, the bed reaches the magnetic shielding space and begins to collect signals. After the magnetocardiogram detection module 400 is positioned, the lead screw of the bed bottom assembly 100 is used for transmission to send the bed board 301 assembly 300 and the magnetocardiogram detection module 400 into the magnetic shielding barrel for data collection.

[0029] After adopting the above technical solution, the bed uses the ball screw 109 to send the test subject outside the testing environment. An additional linear module 304 is added to the bed to help the magnetocardiogram testing equipment perform secondary positioning, which can enable the testing equipment to obtain higher quality test data.

[0030] The magnetocardiogram (MCC) detection module 400 includes a base plate and a probe lifting module 402. The base plate and the linear module 304 are connected by screws, allowing the MCC detection module 400 to move together. A roller assembly 306 is located above the other end of the bed board 301, with rollers 306 rolling on it. An adapter block 305 is connected to the base plate via screws, sharing the load of the linear module 304 and providing guidance. This also increases the lifespan of the linear module 304 and reduces maintenance costs. The bed board 301 motor transmits power to the linear module 304 via a coupling assembly 303. When the MCC detection module 400 moves to the designated position, the bed board 301 motor stops, and the probe lifting module 402 is then manually lowered to the appropriate position, completing the positioning of the MCC detection module 400. This design allows for more precise positioning of the MCC detection module 400.

[0031] The magnetocardiogram measuring device 500 is equipped with an internal guide rail 501. The rollers 306 contact the internal guide rail 501, which supports the bed during its movement, reducing linear friction and making the bed run more smoothly.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
