Description
Technical Field
The invention relates to bed-passing equipment for critically ill patients, in particular to a safe bed-passing trolley for critically ill patients and a using method thereof.
Background
The critical patients often need to carry out various examinations and operations, and the patients need to be transferred among a ward, an examination room and an operating room by using a trolley, and the trolley is used for transferring the patients from a sickbed to an examination table or an operating table. At present, most of the bed-passing vehicles in hospitals are single beds (stretcher vehicles) with casters, when a patient is transported, the family members and medical staff are required to lift up the bed sheets, the patient is transported to the bed-passing vehicles by the bed sheets, then the bed sheets are pushed to an examination room or an operating room, then the family members and the medical staff transport the patient to an examination table or an operating table by the bed sheets, 3 to 5 persons are required to get on or off the patient every time, and therefore, the problems that the number of nursing staff in a ward is large, the noise is large, the work order is disordered, and the recovery of the patient is influenced are easily caused; moreover, the waste of personnel to a great extent is caused, and the secondary injury to the patient is easily caused in the carrying process due to the fact that the personnel are too many and complicated.
In order to solve the above problems of the existing bed-passing vehicle, there is a technical scheme disclosed for improving the bed-passing vehicle for the patient, for example, chinese patent application No. 201611215018.9, published as 2017, 5 and 17, the name of the invention creation is: the utility model provides a stretcher, this application relates to a stretcher, and this stretcher includes the frame body, fixes stretcher and activity stretcher, and the frame body includes two foundation beams and the crossbeam that set up side by side, and the both ends of crossbeam are fixed to be set up at the rear portion of foundation beam, and crossbeam and foundation beam constitute door shape supporter. When the stretcher is used, the stretcher vehicle is moved to the vicinity of a sickbed, the length direction of the stretcher is parallel to the length direction of the sickbed, and the movable stretcher part is upwards and clockwise opened; the piston stroke of the hydraulic cylinder is controlled, and the height of the stretcher plate I for fixing the stretcher part is adjusted to enable the stretcher plate I to be flush with the surface of the sickbed; moving the stretcher vehicle to enable the stretcher plate I to be inserted into one side below the body of the patient to be transferred; the movable stretcher part is rotated anticlockwise, the stretcher plate II is inserted into the other side below the body of the patient to be transferred, and the whole patient is borne by the stretcher plate II and the stretcher plate I; the piston stroke of the hydraulic cylinder is controlled, and the heights of the stretcher plate I and the stretcher plate II are increased to enable the stretcher plates to be away from the surface of a sickbed; moving the stretcher vehicle to separate the stretcher board I and the stretcher board II from the surface of the sickbed; pulling the support rod and opening a bracket embedded in the support rod to enable the bracket to be in a parallel state with the bottom surface of the stretcher plate I and the bottom surface of the stretcher plate II; controlling the piston stroke of the hydraulic cylinder, reducing the heights of the stretcher plate I and the stretcher plate II, and enabling the bracket to support the stretcher plate I and the stretcher plate II; moving the stretcher vehicle to transfer the patient to a required position; the piston stroke of the hydraulic cylinder is controlled, the heights of the stretcher plate I and the stretcher plate II are increased, and the bottoms of the stretcher plate I and the stretcher plate II are separated from the upper plane of the bracket; the bracket is retracted, and then the supporting rod is put down; moving the stretcher vehicle to enable the stretcher plate I and the stretcher plate II to be arranged on the sickbed and positioned right above the sickbed, if the stretcher plate I and the stretcher plate II are higher than the surface of the sickbed, operating the piston stroke of the hydraulic cylinder to adjust the height, and enabling the stretcher plate I and the stretcher plate II to be arranged on the surface of the sickbed; rotating the movable stretcher part to place one side of the back of the patient on the surface of the sickbed; moving the stretcher vehicle to move the stretcher plate I out of the other side of the back of the patient to finish the movement of the patient; and rotating the movable stretcher part to enable the stretcher plate II to be flush with the stretcher plate I, and moving the stretcher to a preset position. The stretcher board I and the stretcher board II of the application grab the patient from two sides of the body of the patient by utilizing the extension and retraction of the hydraulic cylinder in the arc-shaped support arm, the design is unique, and the stretcher board I and the stretcher board II have a better effect on the condition that a sickbed is planar, but for nuclear magnetic resonance and other examination equipment, most of examination bed surfaces are arc-shaped, and the equipment is difficult to realize smoothly in practical use, is difficult to grab and is easy to clamp the patient; in addition, the stretcher is complex in mechanism, operation is not easy to master, the chassis is not suitable for the existing sickbed, due to the fact that the lower portion of the existing sickbed used in the hospital is provided with the frame and other obstacles, the length of the grabbing device is not enough, the grabbing device can be overturned, and potential safety hazards exist.
In addition, the inventor has also proposed patent number zl201692620.x on 2016, month 10 and 12, entitled: the patent application of a plugboard type patient transfer trolley mainly comprises an underframe, a lifting device arranged on the underframe, a support frame arranged on the lifting device, a board frame, more than two plugboards, a plugboard translation mechanism, a plugboard tilting mechanism and a board frame tilting mechanism, wherein the plugboards are arranged on the board frame through the plugboard translation mechanism, the plugboard tilting mechanism is arranged below the plugboards, the board frame tilting mechanism is arranged between the support frame and the board frame, and the board frame is rotatably connected with the support frame. During the use, the picture peg inserts patient's health lower part in proper order, and a certain angle can be leaned on to preceding picture peg after inserting patient's body, forms the clearance between a patient health bed surface to make things convenient for next plug to insert, one person can accomplish the operation, and convenient to use can prevent effectively that patient from receiving the secondary injury. However, the transfer action of the application is complex, the number of the actions to be executed by the plug board is large, the time required for carrying the patient at one time is long, and the complex mechanism causes high manufacturing cost and high failure rate.
Therefore, further improvement of the existing passing trolley (transfer trolley) is needed to improve the safety of the patient during the transportation process and improve the transportation efficiency.
