Description
Technical Field
The invention relates to a medical transfer trolley, which is mainly used for transferring a severe patient between a sickbed and an examination table or an operating table, in particular to a hoisting type transfer trolley for the severe patient and a using method thereof.
Background
The seriously ill patient needs to perform various examinations and operations, etc. frequently, the patient needs to be transferred between a ward and an examination room or an operating room by using a transfer trolley, and the transfer trolley is used for transferring the patient from a sickbed to an examination table or an operating table. At present, most transfer vehicles (transfer beds) in hospitals are single beds (stretcher vehicles) with casters, when a patient is transported, family members and medical personnel are required to lift a bed sheet, the patient is transported to the transfer vehicle by the bed sheet and then is pushed to an examination room or an operating room, then the patient is transported to an examination table or an operating table by the bed sheet by the family members and the medical personnel, 3 to 5 persons are required to get on or off the patient each time, so that a plurality of nursing personnel in a ward, large noise and disordered working order are easily caused, and the recovery of the patient is influenced; 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 view of the above-mentioned shortcomings of the prior art patient transfer vehicles, the prior art has developed improvements. For example, the applicant has proposed patent number zl201610892620.x, 10/12/2016, 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.
For example, the name of chinese patent number ZL200420064433.5 is: a patent application of a lifting operation carrier is published and authorized on 5.10.2005, two ends of the carrier are respectively provided with a set of lifting mechanism, the upper end of the lifting mechanism is respectively provided with a set of translation mechanism consisting of an upper cantilever and a lower cantilever, one end of the lower cantilever is respectively provided with a hanging plate, two winding rollers are arranged below the two hanging plates, the winding rollers are provided with through grooves, pressing rods are arranged in the through grooves, hooks are also arranged on the winding rollers, a bed sheet on an operation table can be wound and tightened on the winding rollers to form a mechanism similar to a stretcher, a patient is carried away, the winding rollers are loosened to leave the patient and the bed sheet on the patient table after the operation, the patient can be stably carried from the operation table to the patient table without moving the body, the damage possibly caused by moving the patient is reduced, and the labor intensity of medical staff is reduced. The application proposes that the mode of clamping a bed sheet by two groups of winding rollers is used for realizing patient transfer, the mode does not need to directly contact with a patient, and therefore the safety is better, but in the application, the two groups of winding rollers adopt a translation mechanism consisting of an upper cantilever and a lower cantilever to perform stretching and retracting actions, on one hand, the bearing capacity of the translation mechanism consisting of the upper cantilever and the lower cantilever is poorer, especially when the upper cantilever and the lower cantilever extend for a longer distance, the load borne by the upper cantilever and the lower cantilever is larger, the weight of a patient is difficult to support, and in the process of lifting and retracting the patient, the upper cantilever and the lower cantilever are difficult to retract due to the action of the cantilever force, and the use is very inconvenient; on the other hand, when the two groups of winding rollers extend outwards to lift a patient, the two groups of winding rollers are not properly supported due to the action of the larger cantilever, so that the problem that the carrying vehicle is easy to overturn in the using process is solved; moreover, the structure of this carrier is comparatively complicated, and the operation is inconvenient, and the cost of manufacture is higher relatively, when directly lifting by the patient behind two sets of winding up roller centre gripping sheet, patient's weight is born by the sheet, has the sheet fracture and makes the patient fall the potential safety hazard that causes the secondary damage, and the safety in utilization is relatively poor.
