RU2584672C2 - Wheeled stretcher - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: construction of a wheeled stretcher represents a trolley with a located on it bed with two lateral backs, one of which is made in the form of a plate and is installed on the bed with a possibility of turning and fixation in the vertical position, with its rotation axis making it possible to install it in the same plane with the bed. A platform, on the edge of which projecting in a cantilevered way bed with a turning lateral back is pivotally fixed with a possibility of turning and fixation in the horizontal position, is installed on the trolley with a possibility of changing the height, with the geometrical centre of the bed being located in the part, projecting in a cantilevered way. The claimed construction of the wheeled stretcher makes it possible to move the patient from the trolley onto a hospital bed fast and without too much effort and trauma to the patient with the simultaneous minimisation of painful sensation and possible injuries.

EFFECT: improved performance of the patient transportation.

Description

The invention relates to the field of health, in particular to means for moving patients in medical and other institutions for moving seriously ill patients, and can be used in transporting and moving a patient from one surface to another.

There are various designs designed for nosocomial transportation of patients and their movement from the operating table to a mobile gurney and from a mobile gurney to a bed in a hospital room (A.S. No. 115685, A.S. No. 197867, A.S. No. 1090388, patent RF №1818092, etc.), which use complex designs, such as a manual worm drive, a conveyor belt, a system with a movable carriage, etc.

However, the use of such devices has not found wide application in view of their design features. The analysis of wheelchairs revealed that the kinematic complexity of the mechanisms, the large weight and complexity of the design, reduces their reliability during operation and increases the risk of additional injury to the transported patient.

Known medical wheelchair (patent for utility model RU No. 101633), including a trolley on wheels with a height-adjustable platform, on which the bed is rigidly fixed and pivotally mounted side backs made in the form of plates having a smooth surface facing the patient, with the possibility fixation in the upper vertical position, and their axis of rotation is located in such a way that when turning to a horizontal position, the side backs are located in the same plane with the bed of the wheelchair and serve as transition bridges Do trolley and the operating table or bed.

The device in question has constructive simplicity and provides transportation of patients, but difficulties arise when moving the patient. Moving from the wheelchair is carried out on a sheet, which is a laborious process and requires significant physical effort.

The objective of the invention is to expand the arsenal of existing technical means, increase the reliability, ease of transportation and patient movement with minimal physical costs of staff due to the original design, which is simple and at the same time easy to operate.

The tasks are solved using the proposed design of the functional wheelchair, including a trolley on wheels, a bed, two side backs, one of which, mounted on the bed with the ability to rotate and fix in a vertical position, is made in the form of a plate, the axis of rotation of which allows it to be installed in one planes with a bed. A platform with a possibility of changing the height is installed on the trolley, on the edge of which a cantilever-protruding bed with a pivoting side back is pivotally mounted with a possibility of rotation in a horizontal position, while the geometric center of the bed is located on its console-protruding part.

In the proposed design of the wheelchair, the bed is mounted on the edge of a height-adjustable platform, while part of the bed cantilever extends beyond the platform, and its geometric center is displaced relative to the platform, that is, the structure is made in the form of an unequal arm, the center of gravity of which is shifted relative to the axis of rotation towards the bed , which greatly simplifies and facilitates the movement of the patient from the gurney to the bed. This design of the wheelchair allows, with sufficient simplicity, to ensure the free movement of the patient with minimal physical cost without outside help. The proposed design allows the gurney to drive sideways close to the bed, while the protruding console part of the bed will overlap part of the bed. The patient easily moves onto the bed, sliding along an inclined plane formed by turning the bed and side back, made in the form of a plate and having a smooth surface facing the patient.

When implementing the proposed design of the wheelchair, a technical result is achieved, which consists in a significant increase in the convenience of shifting the patient to the bed and increasing reliability by simplifying the design.

The invention is illustrated by the drawing in FIG. 1, which shows a general view of the functional wheelchair.

The proposed functional wheelchair (Fig. 1) contains a trolley on wheels 1, a bed 2, two side backs 3. One of which is mounted on the bed with the possibility of rotation and fixation and is made in the form of a flat plate having a smooth surface facing the patient. The axis of rotation of the swivel side back allows you to install it in the same plane with the bed, forming a bridge between the trolley and the operating table or bed. On the trolley 1, a platform 4 is mounted with a possibility of changing the height, on the edge of which a cantilever-protruding bed with a pivoting side back is pivotally mounted with a possibility of horizontal positioning, while the geometric center of the bed is located on its cantilever-protruding part.

The proposed functional wheelchair is operated as follows. Transportation of the patient is carried out with raised up and fixed side backs 3 in order to ensure its safety. Next, the gurney with the patient is rolled up close to the bed, the wheels of the trolley 1 are locked and the platform 4 is lowered until the cantilever part of the bed 2 lowers onto the bed. After that, the fixation of the bed 2, located horizontally on the platform 4, is turned off and the pivoting side back 3, mounted on the console end of the bed, is lowered onto the bed mattress. Then we lift the platform 4 up by the lifting mechanism. When lifting platform 4 upward, bed 2 begins to rotate relative to the edge of the platform, resting on the bed with the cantilever end, creating an inclined plane along which the patient moves down to the bed under its own weight. Thus, quickly and without much effort, without injuring the patient, you can move him from the cart to the hospital bed. In this case, pain and the possibility of damage are reduced to a minimum.

The use of the invention allows to provide:

1. The ability to move the patient from the gurney to the bed by moving it independently under its own weight on the inclined surface of the gurney bed, which allows to minimize the painful sensations of the patient.

2. As much as possible to reduce physical activities for personnel.
