Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, in particular to a bed-transfer device for use in a nuclear magnetic resonance (NMR) room. Background Art
[0002] Nuclear magnetic resonance (NMR) examination is an important imaging examination item for clinical disease diagnosis. NMR examination uses the nuclear magnetic resonance characteristics of magnetic nuclei in organisms to form images. The internal structure of NMR electronic equipment is very complex. Its working principle is that in a specific magnetic field environment, radiofrequency pulses are used to excite hydrogen nuclei in the human body, causing the hydrogen nuclei to resonate and absorb energy. After the radiofrequency pulses are stopped, 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 an information device to obtain examination images. Due to the strong magnetic field of the NMR examination equipment emitting radiofrequency waves, there are also many restrictive requirements for patients to enter the NMR examination room for examination. According to the operating procedures of the NMR equipment, it is strictly prohibited to carry ferromagnetic-related substances for NMR examination.
[0003] In view of the above requirements, ordinary patients can get on the NMR examination bed by themselves after removing all ferromagnetic objects they carry. However, for patients with inconvenient mobility or unable to walk, such as those with lower limb fractures, spinal fractures, spinal cord injuries, multiple fractures, and unconscious patients, they rely on ordinary wheelchairs, hospital beds, stretchers, or stretcher trolleys after admission. However, due to the interference and damage of the materials of these devices to the NMR equipment, they are not allowed to enter the NMR examination room. It is necessary for multiple people to cooperate to carry the patient from the entrance of the patient passage in the NMR examination room onto the examination bed (referred to as "bed transfer"). During the handling process, not only manpower and material resources are consumed, valuable treatment time is wasted, but also there is a high possibility of secondary injuries caused by improper handling. Content of the Utility Model
[0004] The utility model provides a bed-transfer device for use in an NMR room, which is convenient for timely and smoothly carrying critically injured patients onto the NMR examination bed and reducing bed transfer.

[0019] As Figures 1 to 6 shown, the present utility model includes a body 1, a support plate 2, a bed-crossing mechanism, rollers 3 and a liftable protection mechanism. The rollers 3 are arranged at the bottom end of the body 1. The support plate 2 is fixedly arranged on the top of the body 1. The bed-crossing mechanism is arranged on the support plate 2. The liftable protection mechanism is arranged on both sides of the support plate 2, and the liftable protection mechanism is higher than the bed-crossing mechanism. Through the above arrangement, the patient is moved from the hospital bed or the ambulance onto the bed-crossing mechanism, and then the patient is directly pushed into the MRI examination room. Then, the bed-crossing mechanism is docked with the moving bed of the MRI examination equipment, and by pushing the bed-crossing mechanism onto the moving bed, the examination can be carried out, reducing the need for bed-crossing.
[0020] Referring to Figure 2 and Figure 3 , for the convenience of movement, the bed-crossing mechanism includes a supporting plate 5 and rolling wheels 6. There are several groups of the rolling wheels 6. A guide groove 7 is arranged on the support plate 2. The rolling wheels 6 are spaced and installed at the bottom of the supporting plate 5, and the bottom ends of the rolling wheels 6 fall into the guide groove 7. Both the supporting plate 5 and the rolling wheels 6 are made of plastic material. The body 1 and the liftable protection mechanism are made of non-magnetic stainless steel material. The rollers 3 are high-elastic plastic steel rubber wheels.
