[0002] Magnetic resonance imaging can help doctors diagnose and evaluate various diseases and health conditions of patients. An MRI examination usually takes 10-20 minutes, and some examinations may take half an hour or even an hour. During the MRI examination, doctors hope to monitor the patient's electrocardiogram, blood oxygen saturation, blood pressure, body temperature, respiration, pulse rate and other physiological parameters in real time to ensure the patient's safety.

[0003] However, due to the strong magnetic field environment of the MRI room, ordinary monitors cannot work normally under such strong interference. Currently available MRI monitors either use ordinary monitors with shielding frames; or place the monitors outside the MRI room and only connect the accessories to the MRI room; or can only monitor some parameters inside the MRI room, which cannot conveniently meet the monitoring of patient physiological parameters in the MRI room.

[0004] Therefore, the prior art needs to be improved. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The embodiment of the present application discloses a monitor host for magnetic resonance imaging.

[0027] Reference Figures 1 to 5 The monitor host includes a base 1, a support rod 2, a main box 3 and a display module 4. Specifically, the base 1 is used as the installation base of the monitor host as a whole. The support rod 2 is in the shape of a long strip. The lower end of the support rod 2 is arranged on the upper side of the base 1. In order to facilitate the wiring between various devices, the support rod 2 is arranged to be a tubular thin-walled shape. In this embodiment, the support rod 2 is made of non-magnetic metal, the main box 3 is arranged at the upper end of the support rod 2, the main box 3 is used to detect the patient's physiological parameters, and the display module 4 is arranged on a side of the main box 3 away from the support rod 2. The display module 4 is electrically connected to the main box 3, and the display module 4 is used to display the data of the physiological parameters detected by the main box 3. In this embodiment, the shells of the base 1, the main box 3 and the display module 4 are all made of non-magnetic metal. Through the setting of the non-magnetic metal, the base 1, the main box 3 and the display module 4 each form a shielded main body, which can avoid the situation where the detection parameters of the monitor in the magnetic resonance environment have errors, and reduce the influence of the magnetic field on the monitor equipment in the magnetic resonance environment.

[0028] A battery module is arranged inside the base 1. The battery module serves as the power supply basis of the monitor and is installed inside the base 1 through non-magnetic screws. A parameter management module is arranged in the main chassis 3. In this embodiment, the parameter management module includes multiple parameter boards 34. The multiple parameter boards 34 are used to detect different physiological parameters of the patient. The multiple parameters include NI BP boards, CO2 boards, body temperature boards, etc. The multiple parameter boards 34 are arranged inside the main chassis 3 through non-magnetic screws according to their own shapes and sizes. In this embodiment, in order to reduce the connection between the parameter boards 34 and the display module 4, a parameter management board 35 electrically connected to the multiple parameter boards 34 and the display module 4 is also arranged inside the main chassis 3. The parameter management board 35 is used to collect parameter data from each parameter board 34 and forward it to the display module 4 in a unified manner. The forwarding of the parameter management board 35 can greatly reduce the number of connections.

[0029] A control management module is provided on the display module 4 , and the control management module is electrically connected to the parameter management board 35 , so as to integrate the data measured by the parameter management module and display it.

[0030] The outer shell of the host case 3 includes a host bottom shell 31, a host upper cover 32 and a host panel 33. A placement groove 311 is arranged on the upper side of the host bottom shell 31, and one side of the placement groove 311 is opened. In the present embodiment, the host bottom shell 31 is composed of a bottom plate and a U-shaped plate. The bottom plate serves as the bottom of the placement groove 311, the opening of the U-shaped plate serves as the opening of the placement groove 311, and one side of the U-shaped plate serves as the notch of the placement groove 311. The host upper cover 32 is arranged at the notch of the placement groove 311, and the host panel 33 is arranged at the opening of the placement groove 311. The host upper cover 32 and the host panel 33 are fixedly installed on the host bottom shell 31 by non-magnetic screws to form an accommodation space inside the host case 3. The host panel 33 is provided with an external interface of the magnetic resonance monitor, such as a power on / off button, an optical fiber body temperature probe interface, and a NI BP air pipe, CO2 air pipe, etc., and the host bottom shell 31, the host upper cover 32 and the host panel 33 are all made of non-magnetic materials. At this time, the design method can combine and install the host bottom shell 31, the host upper cover 32 and the host panel 33 in pairs, leaving one for easy overall disassembly.

[0031] In order to avoid the high magnetic field environment in the magnetic resonance environment from affecting the modules in the mainframe box 3, a layer of μ metal is coated inside the mainframe box 3, that is, a layer of μ metal is coated on the inner wall of the chamber formed by the mainframe bottom shell 31, the mainframe upper cover 32 and the mainframe panel 33. Since μ metal has extremely high magnetic permeability, when an external magnetic field acts on μ metal, the magnetic field lines will preferentially pass through μ metal instead of penetrating into the shielding body. This high magnetic permeability enables μ metal to form a low magnetic resistance channel, thereby limiting the magnetic field within the shielding layer and preventing the magnetic field from diffusing into the mainframe box 3. At the same time, eddy currents will be generated on the surface of μ metal. These eddy currents will generate a reverse magnetic field to offset the effect of the external magnetic field, and the high conductivity of μ metal enables it to absorb part of the electromagnetic energy, further weakening the magnetic field strength.

[0032] In order to facilitate the installation and disassembly of the monitor, a first slot 11 is provided on the upper side of the base 1. The shape of the first slot 11 is adapted to the shape of the support rod 2 so that the lower end of the support rod 2 can be inserted. A second slot 312 is provided on the lower side of the host box 3. The second slot 312 is arranged opposite to the notch of the first slot 11. The first slot 11 and the second slot 312 are respectively used for the two ends of the support rod 2 to be tightly inserted, so as to ensure that the external magnetic field does not enter the host from the gap between the support rod 2 and the first slot 11 and the second slot 312. In the present embodiment, the support rod 2 can be inserted into the first slot 11 and the second slot 312 by means of conductive glue or non-magnetic screws. The support rod 2 can be an integrated structure or can be formed by splicing two sections of non-magnetic metal tubes. It can also be split into two non-magnetic metal tubes with the same function to connect the main body bottom shell 31 and the base 1 as needed. In order to facilitate wiring, a through hole connected to the inside of the base 1 is provided on the bottom or side wall of the first slot 11, and a through hole connected to the placement slot 311 is provided on the bottom or side wall of the second slot 312.

[0033] The shell of the display module 4 includes a display frame 41, a display screen 42 and a shielding touch screen 43. The display frame 41 is made of non-magnetic material. A mounting groove 411 is provided on one side of the display frame 41. The mounting groove 411 is used to place the display screen 42. The display screen 42 and the shielding touch screen 43 are fixed to the notch of the mounting groove 411 of the display frame 41 in turn by non-magnetic screws or conductive glue to form a closed shielding space on the front of the display frame 41. A box body 412 for placing a control management module is provided on the back of the display frame 41, and the box body 412 is connected to the mounting groove 411 so that the control management module and the display screen 42 can be connected by wiring. In order to facilitate the installation and disassembly of the display frame 41, a mounting hole 321 is provided on the main cover 32. The mounting hole 321 is provided from the direction of the hole on one side. The cross-section is rectangular, and a mounting protrusion 413 is provided on the lower side of the display frame 41. The mounting protrusion 413 is adapted to the shape of the mounting hole 321 so as to be inserted into the mounting hole 321. When the mounting protrusion 413 is inserted into the mounting hole 321, the outer wall of the mounting protrusion 413 will fit tightly with the inner wall of the mounting hole 321 to prevent the external magnetic field from entering the main chassis 3 through the gap between the mounting protrusion 413 and the mounting hole 321. In order to improve the installation stability of the display frame 41, the mounting protrusion 413 is connected to the main chassis 3 by screws to ensure the stability of the display module 4. At the same time, a plurality of external wireless communication interfaces are also provided outside the display frame 41 for connecting remote display devices and other wireless parameter modules, such as ECG, SPO2, etc.

[0034] In order to improve the functionality of the monitor, the following settings are made accordingly: first, an alarm light 5 is provided on the back of the display frame 41. The structure of the alarm light 5 can be in the form of a buzzer light. When the patient's physiological parameters fluctuate greatly or cannot be displayed, the alarm light 5 will sound an alarm to alert the medical staff and facilitate the medical staff to take corresponding actions. The alarm light 5 is electrically connected to the control management module of the display module 4, which can provide power to the alarm light 5 and can be displayed on the display screen 42, further improving the functionality; second, a plurality of legs 12 are provided on the peripheral side of the base 1, and the plurality of legs 12 are evenly distributed on the base 1. In this embodiment, In the example, four legs 12 are provided, and the four legs 12 are respectively provided at the four corners of the base 1 to expand the supporting area of ​​the base 1 so as to make the entire monitor host more stable, and universal wheels 13 are provided on the lower sides of the four legs 12, and the universal wheels 13 are also made of non-magnetic material to avoid being sucked away in a strong magnetic environment. Under the action of multiple universal wheels 13, when the monitor is moved as a whole, the monitor can be moved as a whole with less effort, which is convenient for the operation of medical staff, and in this embodiment, the structure of the universal wheel 13 is a self-locking universal wheel 13, which can be locked when it is not needed to move to prevent the universal wheel 13 from driving the monitor host to move.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
