Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of emergency patient transfer device, in particular to an emergency patient transfer device. BACKGROUND

[0002] Medical transfer refers to the process of transferring patients from one location to another in the medical field for further treatment or placement, which includes transferring patients from dangerous areas to safe areas, from places with insufficient medical resources to places with abundant medical resources, and transferring equipment mainly includes transfer beds and stretchers. The transfer equipment is mainly applied to emergency departments, operating rooms, ICUs, wards and other places in hospitals, which can improve the efficiency of patient transfer, reduce the work intensity of medical staff, reduce the risk of nursing, and protect the safety of patients. In addition, these devices also play an important role in disaster rescue, urban emergencies and patient transfer to hospitals.

[0003] The patient transfer device is usually applied to the movement of seriously ill patients, and such patients usually have the characteristics of being unable to move normally. During the transfer process, the patient needs to be moved from the bed to the transfer device. At this time, since the patient cannot move independently, medical staff need to move the patient to the transfer device. When the patient's weight is small, the medical staff have the ability to move the patient. When the weight of the patient is large, it is very laborious for the medical staff to move the patient. When the seriously ill patient needs emergency treatment, the patient needs to be quickly moved to the operating room. At this time, the transfer device needs to be quickly moved during the movement process. Since there are many people in the hospital, the transfer device needs to be braked in emergency when it is quickly moved.

[0082] More specifically, in the embodiment, when a sudden situation occurs on the moving path during the movement of the severe patient transfer device by pushing the handle three 6, the severe patient transfer device needs to be slowed down, and then the medical staff pulls the handle three 6, and due to the inertia of the severe patient transfer device during the movement, the relative displacement between the handle three 6 and the bottom plate 9 is generated, the handle three 6 drives the connecting plate one 44 to move, the baffle frame 46 moves, and the spring one 42 is stretched, the movement of the baffle frame 46 drives the pulling plate one 45 to slide in the baffle frame 46, and further drives the curved rod two 31 to be angularly deflected, so that the keel frame 25 is slightly deflected with the end connected with the bottom plate 9 as the shaft, so that the patient changes from horizontal lying to lying with an inclined angle, thereby offsetting the displacement of the patient caused by the inertia, and further reducing the risk of falling of the patient during the transfer, and avoiding secondary injury to the patient;

[0083] The setting of the inclination assembly, by generating relative displacement between the handle three 6 and the bottom plate 9 when decelerating, further makes the keel frame 25 slightly deflect with the end connected with the bottom plate 9 as the shaft, so that the patient changes from horizontal lying to lying with an inclination angle, thereby offsetting the displacement of the patient under the action of inertia, further reducing the risk of falling of the patient during the transfer process, avoiding secondary injury to the patient.

[0084] Working principle: the use of the severe patient transfer device has the following steps:

[0085] The height of the bottom plate 9 is adjusted by rotating the handle two 8 to drive the threaded rod one 10, so that the bed plate 5 is aligned with the height of the patient's bed. Rotating the handle one 47 drives the rotating rod one 48 to rotate, so that the bed plate 5 moves and approaches the patient's back. The rotating rod one 48 further rotates the sleeve one 51, which cooperates with the limiting rod two 54 to realize the reciprocating left and right horizontal movement of the limiting column one 52, further driving the bed plate 5 to slightly horizontally move left and right when moving towards the patient's back, and simultaneously driving the connecting column one 60 to move left and right, reciprocating the piston sheet 39 in the piston cylinder 36, and then pumping the gas into the air bag 3 through the hose one 33 to lift the air bag 3, and then making the suction piston cylinder 36 in the air bag 3, so that the air bag 3 is deflated. After the patient is scooped on the bed plate 5, the handle one 47 is reversely rotated to reversely rotate the gear ring one 49, so that the bed plate 5 is retracted on the keel frame 25. Then pinch the handle 4 and the clamping block 22, pull the handle 4 upwards to make the curved rod three 19 perpendicular to the fixed frame one 17, then release the clamping block 22, so that the clamping block 22 makes the trapezoidal block 24 clamped in the clamping frame 20 under the action of the telescopic restoring rod 21, further preventing the curved rod three 19 from restoring, thereby achieving the purpose of lifting the handle 4 to protect the patient. Then use the handle three 6 to push the severe patient transfer device to move. When an emergency occurs on the moving path, the severe patient transfer device needs to be decelerated, so that the handle three 6 and the bottom plate 9 generate relative displacement, the handle three 6 drives the connecting plate one 44 to move, the baffle frame 46 moves, and the spring one 42 is stretched. The movement of the baffle frame 46 drives the pull plate one 45 to slide in the baffle frame 46, thereby further driving the curved rod two 31 to deflect, so that the keel frame 25 slightly deflects with the end connected with the bottom plate 9 as the shaft, further making the patient change from horizontal lying to lying with an inclination angle, thereby offsetting the displacement of the patient under the action of inertia, further reducing the risk of falling of the patient during the transfer process, avoiding secondary injury to the patient.
