Description

Medical shovel type stretcher wheelchair
Technical Field
The invention relates to a medical appliance, in particular to a medical shovel stretcher wheelchair.
Background
At present, a shovel stretcher widely applied to a pre-hospital 120 emergency center consists of two mutually symmetrical and separated half-width lifting frames, each half-width lifting frame consists of a head back rod, a shovel-shaped head back plate, a lower limb rod and a flat lower limb plate, the head back rod and the lower limb rod are both L-shaped, an upper vertical rod of the head back rod is parallel to a lower limb rod vertical rod of the lower limb rod and is arranged above the outer side of the lower limb rod vertical rod, a head back rod hole and a lower limb rod hole are respectively arranged at the outer side and the middle outer side of a middle interlayer of the head back plate, the middle lower part of the upper vertical rod of the head back rod is inserted into the head back rod hole and is fixed at the outer side of the head back plate, and the inner side of the head back plate and the lower limb plate are positioned on the same plane; the middle upper part of the lower limb rod vertical rod of the lower limb rod is inserted into the lower limb rod hole, the outer side of the lower limb plate is fixed at the middle lower part of the lower limb rod vertical rod of the lower limb rod, the lower end of the head backboard is provided with an adjusting valve for adjusting the length of the lower limb rod, and the two half lifting frames are spliced into a whole through the upper cross rod end part of the head backboard and the male and female eye-splice (namely the eye-splice lock) with the button at the lower cross rod end part of the lower limb rod.
When in use, the utility model is characterized in that: the upper end and the lower end of the shovel stretcher are respectively provided with a button lock, and emergency personnel press the button of the button lock to unlock the stretcher, and the left half and the right half are separated. Taking a left lateral position of a patient, placing a right half stretcher under the right half of the patient, turning the patient to the right half position, placing the left half stretcher under the left half of the patient, locking a buckling lock, lying the patient, and lifting the patient; the patient is lifted to the plane, the button of the button lock is pressed to unlock, and the left half stretcher and the right half stretcher are extracted from the two sides, so that the patient is put down.
The back plate shovel stretcher has the advantages of being capable of quickly lifting and putting down a patient, adjustable in length and simple and convenient to operate, but has the following disadvantages: 1. when the existing shovel stretcher is lifted, a patient can only lie down and is not suitable for sitting; if the sitting position is needed, the cotton quilt needs to be padded on the back of the patient, the sitting position is extremely unstable, and the patient is extremely easy to fall off the stretcher. However, in the pre-hospital emergency, most patients can take the sitting position except for a small part of patients such as coma, shock, spine fracture, pelvis fracture and the like, and in addition, some patients can take the sitting position, for example, patients with dyspnea and heart failure can get the lying position to aggravate the illness state and even die; 2. the wheel is not arranged, so that the sliding can not be realized, at least 2 people are required to lift the sliding, more people are required, and the labor is wasted; along with the rapid increase of the elevator room, the patient can take the sitting position and push the elevator more easily and conveniently, and the patient is not forced to take the lying position and lift the elevator by two people; 3. the carrying and turning are difficult in a narrow corridor, and a short elevator cannot enter; 4. when the stretcher is lifted, the patient takes a lying position, the form is long, the gravity center is unstable, the patient is not careful, and the patient can fall down from the stretcher; 5. the medical cabin of the ambulance is narrow, so that the ambulance can not be put on a shovel stretcher and a wheelchair; with the rapid development of cities, the shovel stretcher with the pre-hospital 120 emergency utilization rate of more than 85% is not suitable for the current needs, and corresponding technical innovation is needed.
