Description

Technical Field

[0001] The invention relates to the technical field of nuclear medicine, in particular to an adjustable nursing device for nuclear medicine bedridden patients. Background Art

[0002] In the field of nuclear medicine, bedridden patients often need to receive long-term observation and care due to their condition. The Chinese patent application with application number 201821132069.X discloses "a nuclear medicine bedridden patient care device, comprising a bed, four telescopic rods are evenly distributed between the bed and the base, five sliders are evenly distributed on the upper side of the bed, five slide grooves are provided on the upper end surface of the bed respectively matching the five sliders, and a limiting mechanism for limiting the sliding of the slider is provided on the slider, and a fixing mechanism is provided on the side of the five sliders away from the bed, and a first nylon webbing is provided on one side of the bed, one end of the first nylon webbing is fixedly connected to the bed, and the end of the bed away from the first nylon webbing is fixedly connected to the first nylon webbing buckle. The utility model has a reasonable structure, and the utility model can limit the patient's head, arms, waist, and legs. The limiting device can adjust the relative position on the bed, which is suitable for people of different body shapes, and helps to reduce motion artifacts caused by the movement of patients in the nuclear magnetic resonance imaging device, and improve the quality of the acquired image."

[0003] This technical solution only solves the problem that bedridden patients are prone to movement and artifacts during medical image acquisition. In the nuclear medicine department, it is often inconvenient for bedridden patients to move from the hospital bed to the scanning bed of the magnetic resonance imaging device, so they often need assistance from nursing staff and family members.

In addition, there are often large differences in the body shape of patients, and the existing nursing devices for mobile patients are often difficult to adjust according to the patient's body shape. After the patient is moved to the scanning bed, the patient's position needs to be adjusted to facilitate image acquisition. The existing limit device has many components and complicated operations, resulting in a long preparation time before image acquisition. Summary of the invention

[0042] Working principle: When the present invention is in use, the hospital bed is pushed between the two movable bases 1, and then the first double-axis motor 502 is started, and the first double-axis motor 502 drives the first worm 503 to rotate. When the first worm 503 rotates, the first double-axis threaded rod 402 is driven to rotate through the first worm wheel 504. When the first double-axis threaded rod 402 rotates, the two translation seats 403 are driven to move away from the middle of the first double-axis threaded rod 402 at the same time. At this time, the lifting frame 401 is driven to descend through the connecting rod 404, so that the lifting rod 407 follows the lifting frame 401 to descend, and the lifting rod 407 stops when it descends to the height of the hospital bed;

[0043] Then, the second double-axis motor 602 is started, and the first transmission shaft 603 is driven to rotate by the second double-axis motor 602, so that the first bevel gear 604 rotates along with the first transmission shaft 603. When the first bevel gear 604 rotates, the second transmission shaft 605 is driven to rotate by the second bevel gear 606. When the lifting frame 401 is raised or lowered, the second worm 609 is driven to rise or fall. In this process, the second worm 609 is raised or lowered on the second transmission shaft 605. When the second transmission shaft 605 rotates, the second worm 609 is driven to rotate by the shaft key 607, and the second worm gear 608 is driven to rotate by the second worm 609, so that the second bidirectional threaded rod 40 5 follows the rotation of the second worm gear 608. When the second bidirectional threaded rod 405 rotates, the two translation sleeves 406 are driven to move in the direction of the second worm gear 608. The translation sleeves 406 drive the lifting rods 407 to move at the same time to lift up the patient. When one U-shaped rod 408 away from the scanning diagnosis table 701 moves to the patient's armpit and the other U-shaped rod 408 moves to the lower part of the patient's thigh, the movement stops, so that the patient's back is against the U-shaped rod 408 and the top of the U-shaped rod 408 is located at the patient's armpit, the lifting frame 401 is driven in the reverse direction to rise, and the U-shaped rod 408 is driven to rise by the lifting rod 407, so as to lift up the patient.

[0044] When the patient is lifted from the bed, the movable base 1 is pushed to move the slide rail 703 on the movable base 1 along the slide groove 702, so that the patient is lifted onto the scanning diagnostic table 701, and then the lifting rod 407 is driven to descend so that the patient's buttocks can first contact the top of the scanning diagnostic table 701. After the patient is placed on the scanning diagnostic table 701, the patient is separated from the U-shaped rod 408, and then the U-shaped rod 408 is driven to move away from the patient. Then, the position of the head limiting groove 705 is adjusted by the first limiting rod 706, so that the patient's neck is placed in the head limiting groove 705, so as to fix the patient's head, and the position of the arm limiting groove 707 is adjusted by the second limiting rod 708. The patient's arms are placed in the two arm limit slots 707 to fix the patient's arms. The position of the leg limit slots 709 is adjusted by the third limit rod 710 so that the patient's legs can be placed in the two leg limit slots 709 to fix the patient's legs. The first limit rod 706, the second limit rod 708 and the third limit rod 710 are respectively fixed to the limit guide rod 704 by the third limit rod 710, so that the head limit slot 705, the arm limit slot 707 and the leg limit slot 709 are fixed on the scanning diagnosis table 701, so that the patient is difficult to move during image acquisition, thereby improving the image acquisition effect and facilitating medical staff to diagnose.
