Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical auxiliary equipment, in particular to a stretcher for a nuclear magnetic resonance room. Background Art
[0002] Magnetic resonance imaging (MRI) is an important imaging procedure for clinical diagnosis of diseases. MRI uses the magnetic resonance characteristics of a living organism's magnetic nuclei in a magnetic field to perform imaging. The internal structure of MRI electronic equipment is very complex. Its working principle is to use radio frequency pulses to excite hydrogen nuclei in the human body in a specific magnetic field, causing them to resonate and absorb energy. After the RF pulses stop, the hydrogen nuclei emit radio signals at a specific frequency and release the absorbed energy, which is collected by an external receiver and processed by information equipment to obtain an examination image. Because the powerful magnetic field of MRI equipment emits radio frequency waves, there are many restrictions on patients entering the MRI examination room for examination. According to the operating procedures of MRI equipment, it is strictly forbidden to wear materials containing ferromagnetic substances during MRI examinations.
[0003] Given the above requirements, ordinary patients can independently transfer to the MRI examination bed for an MRI scan after removing any ferromagnetic objects. However, patients with limited mobility or inability to walk, such as those with lower limb fractures, spinal fractures, spinal cord injuries, multiple fractures, or those who are unconscious, are required to rely on standard wheelchairs, hospital beds, stretchers, or trolleys upon admission. However, these devices are not permitted in the MRI examination room because their inherent materials can interfere with and damage the MRI equipment. Therefore, multiple individuals are required to collaboratively carry the patient from the patient entrance of the MRI room to the examination bed (referred to as "bed transfer"). This transfer process not only consumes manpower and material resources, and wastes valuable treatment time, but also poses a high risk of secondary injuries due to improper handling. Summary of the Invention
[0004] The utility model provides a stretcher for a nuclear magnetic resonance room, which is convenient for sending critically injured patients to a nuclear magnetic resonance examination bed in a timely and smooth manner, thereby reducing the disadvantages of manual bed transfer.
[0005] The utility model solves the above technical problems through the following technical solutions:
[0006] A nuclear magnetic resonance (MRI) room stretcher cart comprises a main body, a support plate, rollers, and a liftable protective mechanism.

One end of the connecting rod is fixed to the support plate, and the other end is fixed to the rotating shaft after passing through the long slot.
[0009] The MRI room stretcher cart has four rectangular tubular legs mounted below the main body. Each leg is equipped with a universal roller made of highly elastic plastic-steel rubber wheels, connected to the legs with non-magnetic stainless steel rivets. Each roller is equipped with a foot brake. Handles are also located at the front and rear of the main body.
[0010] The above-mentioned stretcher for MRI room, the support plate and rolling wheels are made of plastic, the body and lifting protection mechanism are made of non-magnetic stainless steel, and there is a triangular support structure between the legs and the support plate.

DETAILED DESCRIPTION
[0018] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention.
[0019] like Figures 1 to 5 As shown, the utility model includes a main body 1, a support plate 2, a roller 3 and a liftable protective mechanism, wherein the roller 3 is provided at the bottom end of the main body 1, the support plate 2 is fixed to the top of the main body 1 by resin screws, and the liftable protective mechanism is provided on both sides of the top of the main body 1, and the liftable protective mechanism is higher than the support plate 2, the support plate 2 is carbon fiber or polypropylene, and the support plate 2 is fixed to the main body 1 by resin screws. Through the above arrangement, the patient is moved from the bed or the emergency vehicle to the support plate, and then the patient is directly pushed into the MRI examination room, and the patient can be moved horizontally to the examination bed of the MRI equipment. This avoids the inconvenience of traditional stretchers being unable to enter the MRI examination room and reduces the inconvenience of getting on and off the bed. A connecting plate 5 is fixed to one side of the vehicle body. This allows for seamless connection with the examination bed of the MRI equipment.
[0020] The support plate and the roller are both made of plastic, the body and the liftable protection mechanism are made of non-magnetic stainless steel, and a triangular support frame 14 is provided between the legs 6 and the support plate 2 .

The baffle 8 is located on the top of the lifting block 9. The bottom of the lifting block 9 is semicircular, and the end of the lifting hole 10 is an oblong through-hole. The bottom end of the lifting hole 10 is located in the semicircular part of the bottom of the lifting block 9. The semicircular part of the lifting block 9 also has a long slot 13. The lifting hole runs through the front and back of the lifting block 9. The connecting rod 11 passes through the lifting hole, and the long slot 13 communicates with the middle of the lifting hole 10. One end of the connecting rod 11 is fixed to the body below the support board 2, and the other end passes through the long slot 13 and is fixed to the rotating shaft 12. During use, the left and right baffles are erected, and the push handle is pushed by medical staff or the patient's family, providing strong safety. Under normal circumstances, the baffle 8 is lowered and faces downward.
