Protective device for preventing rabbit blindness in magnetic resonance imaging and using method thereof

Abstract

The invention provides a protective device for preventing rabbit blindness in magnetic resonance imaging and a using method. The protective device comprises a fixed connecting mechanism used for fixedly supporting the head of a rabbit, an atomizing mechanism arranged on the fixed connecting mechanism and an eyeshade connected with the atomizing mechanism. The atomization mechanism comprises a shell used for storing liquid medicine and an atomization assembly, the atomization assembly comprises a pneumatic control turbine, an atomization grid and air supply fan blades, and the atomization gridand the air supply fan blades are located in the shell and connected with an output rotating shaft of the pneumatic control turbine. According to the using method, the atomization grid is driven by the pneumatic control turbine to rotate at a high speed; liquid medicine is impacted into small water drops to be atomized, the atomized small water drops are pulled by the air supply fan blades to be discharged from the atomization outlet and then reach the periphery of the rabbit eyes along the corrugated pipe, entering and exiting from a scanning bed are not needed, repeated use can be achieved,and the rabbit eyes can be kept wet so as to avoid blindness.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance imaging equipment, in particular to a protective device for preventing blindness of rabbits in magnetic resonance imaging and a use method thereof. Background technique [0002] Rabbits are widely used in imaging experiments as a disease model animal in preclinical research. In MRI experiments, a series of imaging scans are generally performed after injecting anesthesia. The imaging time is relatively long, lasting one to two hours, or even longer. After the injection of anesthesia, the eyelids of the experimental rabbits are not closed, but kept open. The temperature of the magnetic resonance imaging magnet room is generally controlled at no lower than 20 degrees Celsius, which is relatively dry, and the air between the equipment and the magnet room is kept to flow alternately, which can easily lead to dry eyes of rabbits and eventually blindness. In order to observe the occurrence an...

AI Technical Summary

Problems solved by technology

The temperature of the magnetic resonance imaging magnet room is generally controlled at no less than 20 degrees Celsius, which is relatively dry, and the air between the equipment and the magnet room is kept to flow alternately, which will easily cause dry eyes of rabbits and eventually blindness in both eyes.

In order to observe the occurrence and development of the disease, the model animals need to repeat MRI scans after a certain time interval. However, the blindness of the rabbit's eyes will affect the rabbit's diet, or even stop eating and eventually die, which is not conducive to the establishment of the disease model. and further long-term follow-up studies

[0003]During the magnetic resonance imaging of rabbits, eye drops or other protective measures should be taken frequently, but the magnetic resonance imaging rabbits are in the center of a strong magnetic field, which is not conducive to protective measures

If you wait for a scanning sequence to be completed, exit the scanning table, apply protective measures, and then proceed to the next scan, the entry and exit of the scanning table need to be repositioned, which not only affects the experimental process, but also makes it difficult to ensure the layer position of the same inspection site before and after entering and exiting. The direction is consistent, which is not conducive to the later image processing

[0004] At present, when conducting magnetic resonance imaging experiments on rabbits, the opening and closing of the rabbit's eyes is not considered or only a hood is applied to cover the eyes, and no consideration is given to keeping the rabbit's eyes moist Sex, not effective against blindness
