Description

Technical Field

[0001] The utility model relates to the technical field of brain magnetic resonance imaging equipment, in particular to an alarm device used for magnetic resonance scanning. Background Art

[0002] Superconducting magnetic resonance imaging systems have been widely used as medical imaging equipment with high precision, wide applicability, and no harm or radiation to the human body. They are another major advancement in medical imaging after CT and are currently one of the most important clinical imaging methods. The emergence of magnetic resonance imaging has greatly promoted progress in the medical field.

[0003] However, the MRI scanning process still brings some problems to patients; the MRI scanning time is longer than that of CT or X-ray, and if it is for a complex lesion, the time required will be even longer; for example, when performing an MRI scan of the brain, patients often feel uncomfortable due to the large amount of noise generated by the operation of the MRI equipment. In addition, some children or patients with claustrophobia will also feel fear and resistance to the enclosed scanning chamber. The long MRI scanning time and the absence of a doctor in the scanning room make it impossible for the doctor in the operating room to observe the patient's specific condition in time. When the patient moves his head unconsciously and wants to move away from the environment, the scan cannot be stopped in time, resulting in motion artifacts, and the correct image cannot be collected, which affects the quality of the image. The doctor cannot make an accurate diagnosis, which wastes the patient's time and delays the timely treatment of the disease.

[0004] Therefore, developing and designing an alarm device that can promptly notify the doctor in the operating room when a patient feels unwell during an MRI scan to avoid affecting the quality of MRI imaging is an urgent problem to be solved at this stage. Utility Model Content

[0029] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0030] Please refer to Figure 1-Figure 3, is an embodiment of an alarm device for magnetic resonance scanning provided by the present invention, comprising a magnet housing 1, a scanning cavity 11 extending into the interior of the magnet housing 1 is provided on one side of the magnet housing 1, and a head coil arranged around the scanning cavity 11 is provided in the magnet housing 1; a bed 2 is connected to a driving component, and the driving component can drive the bed 2 to move between a first position and a second position; in the first position, the bed 2 is located outside the magnet housing 1, and the patient can lie on the bed 2 conveniently; in the second position, at least a portion of the bed 2 extends into the scanning cavity 11, and the patient can undergo a cranial magnetic resonance scan when the bed 2 enters the scanning cavity 11 of the magnet housing 1;

[0031] A button 21 is provided on the side of the end of the bed 2 that extends into the scanning chamber 11. An alarm and a computer are provided on the outside of the magnet housing 1. When the bed 2 is in the second position, the button 21 is connected to the alarm; the computer is connected to the head coil, the drive assembly, the button 21, and the alarm respectively. When the patient becomes unwell and has difficulty keeping his head still, he can press the button 21 to activate the alarm and send a signal to the computer, so that the doctor in the operating room can immediately understand the patient's abnormal condition and decide to pause or terminate the MRI scan.

[0032] Furthermore, when the bed 2 is located at the first position, the button 21 is disconnected from the alarm, which can effectively prevent the patient from accidentally touching the button.

[0033] It should be noted that the button 21 is preferably made of PC material, specifically including a PC twist cover and a PC plastic shell, which will not affect the magnetic resonance scanning; at the same time, the button 21 is protruding from the surface of the bed 2, which makes it easier for the patient to find the button 21, and the user experience is stronger, and there will be no situation where the button 21 cannot be touched during use; further, the color of the button 21 is preferably set to red, which can be distinguished from the color of the bed 2 and is more eye-catching.

[0034] Specifically, the magnet housing 1 and the bed 2 are both arranged in the scanning room, and the alarm and the computer are preferably arranged in the operating room. The alarm can include a buzzer and a warning light, and the computer is preferably set as a computer. When the patient presses the button 21 in the scanning cavity 11, the alarm can simultaneously emit a sound and light alarm, and the computer display interface can also pop up a prompt window to ensure that the doctor can be informed at the first time.

[0035] In this embodiment, please refer to Figure 1 and Figure 3 A light strip 3 is provided on the outer wall of the magnet housing 1, and the light strip 3 is connected to the button 21. When the button 21 is pressed, the light strip 3 can be turned on to attract the attention of medical staff; specifically, the light strip 3 is preferably arc-shaped and arranged around the scanning cavity 11.

The patient can directly communicate with the outside through the call terminal 4, and the doctor can understand the patient's specific condition more timely and accurately.

[0037] Specifically, when the bed 2 is in the second position, the two call terminals 4 should be in a connected state, and the patient can communicate with the outside by pressing the button 21; when the bed 2 is in the first position, the two call terminals 4 should be in a disconnected state to avoid accidental touch by the patient.

[0038] Furthermore, the communication terminal 4 on the bed 2 should be provided with an electromagnetic interference-proof shell to avoid interference between the communication terminal 4 on the bed 2 and the magnetic field of the head coil.

[0039] Furthermore, a filter plate is provided between the scanning room and the operating room. The button 21, the talking terminal 4 on the bed 2 and the light strip 3 are all connected to the computer through cables. The outside of the cables in the scanning room are wrapped with a shielding layer. When the button 21 and the talking terminal 4 are in the disconnected state, they will not affect the magnetic resonance imaging.

[0040] It should be noted that the voice call component is preferably configured as a walkie-talkie.

[0041] In this embodiment, please refer to Figure 1 and Figure 2 The bed 2 and the base 5 can be movably connected by a slider and rail structure. The driving component is arranged between the bed 2 and the base 5. The driving component is preferably set as a screw stepper motor, which can drive the bed 2 to move stably along the base 5.

[0042] Furthermore, a position sensor capable of detecting the real-time position of the bed 2 can be provided on the base 5. The position sensor is connected to the computer. Only when the position sensor detects that the bed 2 has moved to the second position and the computer receives the signal from the patient pressing the button 21, will the alarm, light strip 3 and voice call component be turned on to avoid accidental touch.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
