Technical field

The present invention relates to a kind of for loading and unloading the vehicle arts of patient, more particularly to one kind suitable for hospital It carries patients after surgery or carries the Medical patient bed transport for the patient that those are easy to be damaged again during moving.

Background technique

Currently, Medical transport pushing bed is to move and shift preoperative and postoperative home-bound patient, patient is moved to by hospital bed and is turned Bed is transported, then operating table is moved to by bed transport or needs inspection/treatment equipment or antiport.Especially for the disease with wound People or when carrying out the postoperative patient of serious vertebra, cervical vertebra, thoracic vertebrae, the birth of Medical transport pushing bed reduces the labour of medical staff Intensity, avoids patient's preoperative and postoperative and moves possible secondary injury for several times during transhipment, may such as affect wound or Lesion, both caused considerable distress to patient, was also unfavorable for the healing of post-operative wound.

Existing commercial type or the Medical transport pushing bed used mainly consist of two parts, and a part is for mobile vehicle Body, another part are the moving bed trigger structures that patient is picked for transverse shifting；" the doctor as disclosed in Chinese patent 98205338.X With patient transporter ", the Medical patient transport vehicle include vehicle body and conveying table face (moving bed trigger structure), conveying table face by Conveying roller, driven voller and it is mounted on conveying roller, the conveying strap composition on driven voller, conveying table face can be horizontal under motor effect It translates forwards, backwards.For another example " medical use carrier for transferring patient " disclosed in Chinese patent 200610052776.3, the moving bed trigger structure are adopted The bilayer combination structure for the lower mobile cloth that/above moves cloth and lower moving carriage/with upper moving carriage, specifically include cloth beam frame, Cloth beam, end connector pedestal, clutch gear, upper moving carriage/above move the components such as cloth, lower moving carriage/lower mobile cloth.But this A little Medical transport pushing beds have the following deficiencies:

1, structure problem

Above-mentioned transmission strap (Chinese patent 98205338.X) or upper mobile cloth (Chinese patent 200610052776.3) By driving rubber roller rotation, so that transverse shifting is before and after driving the transmission strap being set on rubber roller or upper mobile cloth with close Or far from operating table/hospital bed, since the transmission of cloth cover needs certain tensile force, with the long tensioning journey for needing to debug cloth cover Degree；Cloth cover is stretched to must just replace to a certain degree, and the guardrail that vehicle body two sides are otherwise arranged in does not close；The cloth cover of the structure Easy left and right walks, and needs to debug；In addition to this, the setting of rubber roller can also cause problems, such as Chinese patent Between 16 mid-rubber roll 15 of Figure of description and end connector pedestal 16 of " medical use carrier for transferring patient " disclosed in 200610052776.3 Existing gap is easy clothes to be involved in rubber roller, it is also possible to which collet is sent out during transporting patient；And there can be rubber roller Aging needs replacing rubber roller, again the problems such as commissioning device operating status.

As Chinese patent 200610052776.3 transmission mechanism in use driven by clutches, clutch use two clutches The mechanical type control structure that gear is conformed to, separated is easy to appear failure the disadvantage is that design structure is complicated；Especially clutch Part, when needing to combine, when two teeth of two clutch gears are uncoordinated, when will cause in conjunction with having some setbacks, and needing to separate, In In the case where two tooth engagements, separation resistance is had, running fix is caused to differ greatly, it cannot the satisfactory transfer work for completing patient Make.

In addition, transmitting strap or moving up and down cloth is the silent conveying cloth of annular, directly connect with patient body Touching, for the main component for directly picking patient；Due to the demand of medical sanitary, transmit strap or move up and down cloth its Cloth cover disinfection is easy to cause cloth cover joint broken, and structural strength is inadequate.

2, hygienic issues

Transmission strap moves up and down cloth and directly contacts with patient body, and it includes bloodstain, human body that cloth cover, which is easy dirty, The stains such as diffusate, therapeutic agent diffusate are the silent conveying cloth of annular due to transmitting strap or moving up and down cloth, It ensconces in machine and is difficult to clean, it is also difficult to which replacement conveying cloth replaces the demolition, installation workload of primary conveying cloth no less than assembling one The workload of new machine, therefore, cloth cover fouling problems can not solve.

3, safety problem

Rubber roller rotation is driven by driving mechanism, thus the mode meeting for driving the transmission cloth being set on rubber roller to be moved forward and backward Cause generation patient to hit end connector pedestal 16 there are maloperation and even drops to bed transport bedstead across end connector pedestal 16 Consequence.Under normal condition, when people lies on transmission cloth, driving mechanism stops driving rubber roller rotation, and transmission cloth remains static, It need to only move and move up and down plate, can be completed and pick to required position.If patient on bed transport, accidentally presses insertion hospital bed Button, patient will occur hit end connector pedestal 16 even to drop to bed transport bedstead across end connector pedestal 16, generate Malpractice.
