Description

Novel intracardiac branch of academic or vocational study first aid transport chair

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a novel intracardiac branch of academic or vocational study first aid transport chair.

Background

Because the disease of intracardiac branch of academic or vocational study type is when the sick, it is very difficult to rescue on the scene, consequently generally adopts the transport chair to transfer patient to intracardiac branch of academic or vocational study rescue room and carry out rescue treatment, but at the in-process of transporting because the road surface is uneven or need go upstairs and downstairs the circumstances such as, inevitable can produce and rock, and this kind rocks and can aggravate the deterioration of patient's state of an illness, has not only increased the rescue degree of difficulty and has also increased doctor's psychological burden. At present, most transport chairs only absorb shock to the rollers, and cannot absorb shock to the contact place between a patient and the chair, so that the shock absorption effect is not good.

Chinese patent (publication number is CN206239616U) discloses a novel chair is transported in intracardiac branch of academic or vocational study first aid, include the backup plate and do the board, the backup plate is located the right side of seat, the equal fixedly connected with handrail in both sides at seat top, the top fixedly connected with air cushion of seat, and the air cushion is located between two handrails, the right side intercommunication of air cushion has the trachea, the trachea is kept away from the one end of air cushion runs through the backup plate and extends to the right side of backup plate, extends to the trachea on backup plate right side and the air outlet intercommunication of fan, and the tracheal top that is located backup plate right side is provided with the pneumatic valve, the right side fixed mounting of backup plate has the controller, and the controller is located the top of pneumatic valve, the controller respectively with fan and pneumatic valve electric connection. However, the novel intracardiac branch of academic or vocational study first aid transport chair that this patent provided does not consider the condition that the transport chair need go up and down the stair, does not consider the inconvenient condition of patient's seat yet.

Chinese patent CN109223331A provides a shock-absorbing wheelchair, the right side position of seat downside terminal surface is equipped with the push wheel, the left side position of seat downside terminal surface is equipped with the bumper shock absorber, the downside of bumper shock absorber is in the same place with the running wheel is installed, the running-board is installed to the left side position of seat, the last safe edge is installed to the upside position of seat, the through-hole has been seted up on the backup plate, the upside position of backup plate is equipped with pushes away the handle, realize fixing to sun umbrella through adding the lifter, this design has solved the problem that traditional user is easily radiated by the sun when going out, and the design of lifter then is convenient for highly adjust sun umbrella, and then convenient to use person adjusts according to specific needs, the gasbag that is located on the seat in addition has then played the purpose of buffering shock attenuation, cooperation damping spring has improved user's travelling comfort.

For example, the Chinese patent document with publication number CN207898598U discloses a convenient transfer chair for cardiology department, comprising a body, wherein the bottom end of the body is provided with a base, one side of the base is fixedly connected with a handle and a pedal, the pedal is positioned in the handle, one side of the bottom end of the base is movably connected with a steering wheel, the other side of the bottom end of the base is fixedly connected with a moving wheel, the moving wheels are connected through a connecting shaft, a crawler is arranged between the two moving wheels, the side end of the crawler is provided with a mounting hole, the side end of the bracket of the utility model is provided with a crawler angle adjusting mechanism, the connecting shaft is movably provided with the crawler, when the transfer chair needs to go down the stairs, the inclination angle of the crawler is adjusted through the crawler angle adjusting mechanism to be parallel to the slope surface of the stairs, then the transfer chair can be, is convenient for placing the infusion bottle. This patent adopts angle adjustment mechanism to adjust the inclination of track in order to solve the problem that track and ground or stair face contact under the condition that the transport chair has born the weight of patient for the track parallels with the stair slope. This kind of solution need not transport the state that the chair converts into "bed", also need not medical personnel to lift the transportation chair, only need rotate the pivot and adjust the track to domatic parallel with the stair to solved the problem that has the regulation degree of difficulty under the condition of bearing patient that the examiner proposed, nevertheless sacrificed the most important function of transportation chair-how reduce the friction between transportation chair and the stair face, thereby be convenient for medical personnel upstairs and downstairs with comparatively laborsaving mode. This patent has only set up the track at the transport chair rear portion, and the transport chair that this patent was disclosed is not the bottom that the track covered the transport chair comprehensively promptly, and the effect of the reduction friction that the track brought weakens, and more importantly patient's weight distribution does not set up the part of track, and the biggest contact part of friction does not reduce the friction through the track between transport chair and the stair promptly, therefore the laborsaving effect that the track actually brought is greatly discounted.

For example, chinese patent publication No. CN205515253U discloses a single-section dual-track stair-climbing wheelchair based on swing of traveling wheels, which includes a wheelchair main body fixed on a track mechanism, two traveling large wheels, a track stair-climbing mechanism and a large wheel swing arm mechanism; the crawler stair climbing mechanism is a bilaterally symmetrical double-crawler mechanism and consists of crawler mechanisms on two sides, a crawler driving motor and a second speed reducer; the large wheel swing arm mechanism can realize stable conversion of motion states. The utility model discloses a combine hand push wheelchair and track building climbing mechanism together ingeniously, overall dimension is the same with ordinary hand push wheelchair, has fine corridor trafficability characteristic, and it is convenient to go out to use, and the nimble characteristics of turning, the arc of installation make the track climb the building mechanism and can install the below of wheelchair seat, and the requirement of focus position when satisfying climbing the building state has still reduced holistic focus when climbing the building simultaneously, makes the person of taking feel safer.
