Shovel type stretcher wheelchair for medical treatment

Abstract

The invention discloses a shovel type stretcher wheelchair for medical treatment. The wheelchair consists of two symmetrical and separated half frames. The wheelchair can take two postures of lying and sitting; a shovel stretcher is obtained after a back rod is laid flat, a sitting rod and a lower limb rod are oppositely flattened and fixed by hooks; snap locks are arranged in the middle of cross rods on a head and neck rod, a lower supporting rod, the sitting rod and the lower limb rod, and when a button is pressed, the left half and the right half of the stretcher can be quickly separated, so that the stretcher can be quickly lifted and lowered when a patient is lying down; when the lower limb rod is shortest, the back rod is vertical, and the sitting surface is unfolded to automatically fix to form the chair, so that the patient is convenient to carry when taking the seat; a horizontal connecting rod of the lower supporting rod is pulled up to enable a supporting rod shaft to be separated from a bayonet, so that the chair can be flattened into the shovel stretcher; rotary wheels at the upper end of the back rod, rotary wheels at the lower end of the back rod and rotary wheels at the lower part of the lower limb rod are convenient to push and pull on the flat ground when sitting or lying, so that personnel and physical strength are saved; and a head and neck rod regulating valve and a lower limb rod regulating valve can regulate the lengths of the head and neck rod and the lower limb rod when the patient is lying, so that the needs of patients with different heights can be met.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a medical shovel stretcher wheelchair. Background technique [0002] At present, the shovel stretcher widely used in the 120 emergency center in front of the hospital is composed of two mutually symmetrical and separated half-width lifting frames. Composition, the head-back bar and the lower branch are both "L" shaped, the upper vertical bar of the head-back bar is parallel to the lower body bar vertical bar of the lower body bar and is on the outer side of the lower body bar vertical bar, and on the outer side of the middle interlayer of the head back plate The head-back rod hole and the lower branch hole are respectively provided on the middle and outer sides. The middle and lower parts of the upper vertical rod of the head-back rod are inserted into the head-back rod hole and fixed on the outer side of the head-back board. The inner side of the head-back board and the lower branch board ...

AI Technical Summary

Problems solved by technology

[0004] Backboard shovel stretcher has the advantages of being able to quickly lift and put down the patient, adjustable length, and simple operation, but has the following disadvantages: 1. The patient can only lie down when the existing shovel stretcher is lifted, and it is not suitable to sit; if it is necessary to take a seat , it is necessary to put a quilt on the back of the patient, and the sitting position is extremely unstable, and the patient can easily fall off the stretcher

However, in the pre-hospital first aid, except for a small number of patients such as coma, shock, spinal fracture, pelvic fracture, etc., who must take the lying position, most patients can take the sitting position. In addition, some patients must take the sitting position, such as dyspnea, Patients with heart failure who take the supine position will aggravate their condition and even die; 2. There are no wheels, and they cannot be pushed and pulled. It is more feasible and convenient, without forcing the patient to take a supine position, and it is difficult for two people to lift; 3. It is difficult to lift in a narrow corridor, and it is difficult to turn, and the short elevator cannot enter; 4. The patient is placed in a supine position when lifting. The center of gravity is unstable, and if you don’t pay attention, the patient may fall off the stretcher; 5. The medical cabin of the ambulance is too small to accommodate a shovel stretcher and a wheelchair; with the rapid development of the city, the utilization rate of the 120 emergency room before the hospital is as high as 85 More than 100% of the shovel stretchers are not suitable for the current needs, and corresponding technical innovations are urgently needed
