Abstract

The invention relates to a bed board adjustable medical go-cart and belongs to the field of medical appliance. In the prior art, the carrying of a patient is conducted by a plurality of persons, and the patient undergoes partly suspension of the body, and change and distortion of body position; and the carrying of an overweight patient is especially hard. The go-cart comprises a pedestal with wheels, wherein a lifting mechanism arranged on the pedestal supports a bed board. The go-cart is characterized in that a two-way movable mechanism for the bed board is arranged between the lifting mechanism and the bed board; and the two-way movable mechanism for the bed board comprises a rotary rod, a bed board translation component connected with the rotary rod, and a bed board rotary component, wherein left and right ends of the rotary rod are fixed with a slide piece which can move along a group of parallel slide rails arranged in the back side of bed board. The go-cart has the advantages of even and stable hold of the patient, even stress, little change of body position and low probability of distortion. Compared with the prior art, the go-cart relieves the pain of the patient, reduces the number of medical personnel, is especially suitable for the carrying of overweight patients, and reaches the strict sanitary standard of the state that the appliance outside the operation room can not enter an operation room.

Description

The bed board adjustable medical patient trolley

[technical field]

The present invention relates to a kind of carrying patient, particularly a kind of bed board adjustable medical patient trolley belongs to medical instruments field.

[background technology]

The patient is at perioperatively, its sick bed from the ward need be lifted in the go-cart pusher operating-table on the operating room, or carry back from the operating-table of operating room on the sick bed in ward.In the actual mechanical process, the preceding elder generation of art lifts to patient in the go-cart and shifts operating room onto outdoors, after go-cart in this go-cart and the operating room integrates with, in order to reduce lift to move number of times and patient's misery, often directly bed board is moved on the go-cart frame in the operating room together with patient, patient is transferred on the operating-table from go-cart, backout is once again for postoperative again.This mode of transport has been brought the bed board of disease carrying germ in the operating room into, does not reach country and must not enter strict sanitary standard in the operating room to the outdoor apparatus of hospital surgical.And in the repeatedly lift to move process, the differing heights that needs height adaptation sick bed, go-cart and the operating-table of manually adjustment go-cart, and the lift to move that relies on 4-5 people to accomplish patient by joint efforts is transferred, often bring very big misery, increase family members' psychological burden to patient, medical personnel are operated concertedness require highly, and the extraordinary patient of lift to move body weight is very painstaking.In addition, for bone injury or internal medicine critically ill patient, lift to move action is easy to cause patient posture to change, increase painful, and patient body is local unsettled and make Body Position Change, distortion in the lift to move process of postoperative, more may cause secondary damage, influence the operative treatment achievement.

[summary of the invention]

The technical assignment of the technical problem to be solved in the present invention and proposition is the defective that overcomes prior art, provide a kind of operation number few, steadily removing patient especially is fit to the extraordinary patient's carrying of body weight and makes handling process reach the bed board adjustable medical patient trolley of state health standards.For this reason, the present invention adopts following technical scheme:

The bed board adjustable medical patient trolley, comprise the base that has wheel, the elevating mechanism that is provided with on the base is supported with a bed board, it is characterized in that being provided with between described elevating mechanism and the bed board bed board bidirectional-movement mechanism, described bed board bidirectional-movement mechanism comprises dwang and connected bed board translation assembly and bed board runner assembly, and two ends, the described dwang left and right sides are fixed with one group of sliding part that parallel sliding track moves that can be provided with along the bed board back side.Bed board translation assembly is set realizes that bed surface moves in the horizontal plane direction along slide rail, centre position near patient couch top, mover bed surface or operating-table table top, shorten patient's level to the distance that moves, after relying on elevating mechanism to adjust height, the bed board runner assembly can make bed board go to the angled back of horizontal plane and realize plugging into patient couch top, mover bed surface or operating-table table top, is convenient to shift patient.Therefore, in the process that shifts, need not patient is raised and translation, only need patient to lie on one's side, then bed board is raise, the translation bed board, rotate bed board to the angle that adapts to, and move to patients back and paste mutually, rotate bed board again to level, and original position is returned in translation, can promote patient has moved, general two medical personnel are the energy complete operation just, and in the whole moving process, patient body relies on bed board all the time, stressed even, Body Position Change is little, and the probability that is distorted is low, has significantly reduced patient's misery and medical personnel's quantity and operation requirement than prior art, particularly be fit to moving of the extraordinary patient of body weight, and reach country and must not enter strict sanitary standard in the operating room the outdoor apparatus of hospital surgical.

For the improving and replenishing of technique scheme, can increase following technical characterictic or its combination:

The described assembly that moves horizontally comprises first worm screw of the translation driver drives that is erected on the rotating turret and is mated and is fixed on first worm gear on the dwang, first worm gear, one side is fixed with co-axial gear, and the bed board back side is provided with the tooth bar that cooperates with gear.During work, translation driver drives first worm screw drives worm gear and rotates, thereby make gear, tooth bar generation relative displacement, make the slide rail at the bed board back side and the sliding part generation relative displacement at dwang two ends, the realization level to flexible two-way move, stable drive is convenient to fine setting, employing has the worm and gear of auto-lock function, accurately the location.

Described bed board runner assembly comprises rotary driver second worm screw that drives and second worm gear that is mated and is fixed on the dwang that is erected on the rotating turret.During work, rotary driver drives second worm screw and rotates, thereby drives second worm gear and dwang rotation, realize bed board positive and negative two-way turn to horizontal plane angled, make lie on one's side patient's back angle of its adaptation, good support patient reduces patient's misery as far as possible.Employing has the worm and gear of auto-lock function, accurately the location.

Described elevating mechanism comprises pressure-oil tank that is arranged on the base and the three-section type elevating lever of fixedlying connected with the rotating turret middle part, and described pressure-oil tank two sides are provided with control stick.Can ride the lifting of control bed board, be convenient to operation and satisfy hygienic requirements.

Described translation driver is joystick or motor.Select for use manually or electric operating according to different environments for use and condition needs.

Described rotary driver is joystick or motor.Select for use manually or electric operating according to different environments for use and condition needs.

The present invention realizes that by distinctive bed board bidirectional-movement mechanism bed board fits closely with treating the carrying patient back, uniform and stable support patient's weight in whole moving process, stressed even, Body Position Change is little, the probability that is distorted is low, significantly reduced patient's misery and medical personnel's quantity than prior art, the carrying that particularly is fit to the extraordinary patient of body weight is moved, and reaches country and must not enter strict sanitary standard in the operating room to the outdoor apparatus of hospital surgical.
