Description
Technical Field
The invention relates to the technical field of medical devices, in particular to a nuclear magnetic resonance examination bed and a method for cleaning a nuclear magnetic resonance scanner.
Background
At present, more and more severe pneumonia patients, in the nuclear magnetic resonance examination, the gas exhaled by the patients can directly pollute the inside of a nuclear magnetic resonance scanner, the pollution to a nuclear magnetic resonance examination area is directly caused, the infection risk of new corona viruses in the nuclear magnetic resonance examination area is increased, if corresponding disinfection measures are not taken for the examination area, the increase of the infection risk of the examination area undoubtedly brings larger disease risk to the patients, meanwhile, the diffusion of infectious diseases can be increased, and the cost expenditure and the material consumption of the society for further spreading the infectious diseases are increased.
At present, in the nuclear magnetic resonance examination process, the examination of each patient cannot be carried out in a flow, reliable and effective way, so that a device capable of automatically disinfecting and sterilizing the nuclear magnetic resonance examination area is urgently needed under the condition that the existing new coronavirus is extremely high in infectivity.
Disclosure of Invention
The invention aims to provide a nuclear magnetic resonance examining table and a method for cleaning a nuclear magnetic resonance scanner, and solves the problem that effective sterilization cannot be automatically carried out in the nuclear magnetic resonance scanner in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:
a nuclear magnetic resonance examining table comprises a table body, a table base and a disinfection and sterilization device arranged on the table body, wherein the table body moves along the table base, the disinfection and sterilization device comprises a plastic arc-shaped frame and an alcohol cotton sheet cleaning mechanism, the plastic arc-shaped frame is arranged on the table body and is close to a nuclear magnetic resonance scanner, and the outer diameter of the plastic arc-shaped frame is matched with the inner diameter of an examining space of the nuclear magnetic resonance scanner;
the clean mechanism of alcohol cotton piece includes alcohol cotton piece, driven rolling wheel, initiative rolling wheel, left side rolling container and right side rolling container, driven rolling wheel and initiative rolling wheel are installed respectively in left side rolling container and right side rolling container, be equipped with the opening on left side rolling container and the right side rolling container respectively, the both ends of alcohol cotton piece are passed and are convoluteed respectively on driven rolling wheel and initiative rolling wheel after the opening that corresponds, be equipped with the supporting part that is used for supporting the alcohol cotton piece on the plastics arc frame.
Among this technical scheme, because the setting of plastics arc frame can provide the shape for the setting of alcohol cotton piece and support, the external diameter of plastics arc frame matches with the internal diameter in nuclear magnetic resonance scanner inspection space, and then when the bed body moved in towards the nuclear magnetic resonance scanner, the inside wall that the alcohol cotton piece that sets up on the plastics arc frame can hug closely nuclear magnetic resonance scanner inspection space removed and realizes the inboard cleaning and disinfection of nuclear magnetic resonance scanner.
By adopting the design, in the moving process of the bed body, the plastic arc-shaped frame moves along with the bed body, so that the cleaning and the sterilization in the examination space of the nuclear magnetic resonance scanner are realized without additional cleaning and sterilizing operation. Because the position that the plastics arc frame is installed and is close to the nuclear magnetic resonance scanner on the bed body, when the bed body removed the patient and has not got into detection area completely yet, the alcohol cotton piece can be in advance to the clean virus killing of nuclear magnetic resonance scanner inspection space inner wall to guaranteed the safe handling of every patient in the nuclear magnetic resonance inspection process, avoided because of the pollution of detection area clean virus killing untimely causing the infection to the patient.
Because be equipped with the opening on left side rolling container and the right side rolling container respectively, the both ends of alcohol cotton piece are passed and are rolled up respectively on driven wind-up pulley and initiative wind-up pulley after the opening that corresponds, only need drive initiative wind-up pulley and rotate and can realize the rolling to the alcohol cotton piece, then the driven wind-up pulley of opposite side emits clean alcohol cotton piece, thereby simple convenient realization is to the change of alcohol cotton piece, and in the in-process of carrying out disinfection to the inspection space, because plastics arc frame can be along with the bed body removes, consequently, only can realize the cleanness virus killing of alcohol cotton piece to nuclear magnetic resonance scanner inspection space by the removal of the bed body, the problem of current unable automatic effective disinfection to the inside of magnetic resonance scanner has been solved, can realize carrying out the flow to the detection area, standardization, reliable, effectual disinfection and sterilization.
Furthermore, in order to conveniently realize the replacement operation of the alcohol cotton sheets, an operating handle which is convenient for operating the driving winding wheel to rotate so as to realize the winding of the alcohol cotton sheets is arranged on the driving winding wheel.
Furthermore, in order to realize the automatic replacement of the alcohol cotton sheets in the moving process of the bed body without manual operation, a driving mechanism for driving the driving winding wheel to rotate is arranged between the bed seat and the driving winding wheel.
Furthermore, in order to better realize the automatic effect of replacing the alcohol cotton sheets and not influence the nuclear magnetic resonance examination effect, the driving mechanism comprises a rack arranged on the bed and a transmission shaft rotationally connected with one side of the bed body, a first bevel gear is arranged at the upper end of the transmission shaft, a gear meshed with the rack is arranged at the lower end of the transmission shaft, a second bevel gear meshed with the first bevel gear is arranged at the end part of the driving winding wheel, and a ratchet structure is arranged between the second bevel gear and the driving winding wheel. It should be noted that the driving mechanism is made of non-metal material, and may be made of plastic material.
This actuating mechanism's design, the in-process that the bed body removed, can realize that the gear drives the transmission shaft and rotate because of the relative displacement of gear and rack, because the transmission shaft rotates with the bed body and is connected, and the upper end of transmission shaft is equipped with first bevel gear, the transmission shaft can drive first bevel gear and rotate, and then through first bevel gear drive second bevel gear rotation, because be equipped with between second bevel gear and the initiative wind-up pulley by the ratchet structure, can realize driving the initiative wind-up pulley rotation when second bevel gear clockwise turning, realize changing the rolling of alcohol cotton piece, when second bevel gear anticlockwise rotation, then unable drive initiative wind-up pulley rotates, also be, only when the bed body moves towards nuclear magnetic resonance scanner, the alcohol cotton piece is changed, the alcohol cotton piece can not be changed under the bed body playback state.
Furthermore, for the convenient installation that realizes the transmission shaft, one side of the bed body is equipped with the mount pad, rotate through the bearing between transmission shaft and the mount pad and be connected.
Further, in order to hide the protection transmission structure, one side of right side rolling container is equipped with the gear cover, first bevel gear and second bevel gear all are located the gear cover.
Further, for the tight effect of subsides of the inboard wall in better realization alcohol cotton piece and the nuclear magnetic resonance scanner, reach better clean effect, the supporting part includes the elastic layer, wears out open-ended alcohol cotton piece and is located the elastic layer.
