Description

Foot control of hospital bed

Technical field

The technical solution concerns the foot control of the hospital bed, resp. actuators for shaping the bed area, especially beds for hospitals, for standard inpatient wards and for residents in nursing homes, social care institutions and other social and senior care facilities, or for home patient care.

BACKGROUND OF THE INVENTION

Standard beds offered on the market today for hospital facilities, or for social, senior care, or home patient care are equipped with bed height adjustment options, tilt of the loading area, ie tilting the individual parts of the loading area, tilting the entire loading area along the transverse or longitudinal axis. These functions are usually controlled by a foot controller, ie switches located under the bed surface. These switches are activated when the patient is operated by medical staff by pressing the foot. However, in such a way of activating the foot switches it is necessary to prevent their accidental and unintentional activation. In the last 15 years, there have been cases where a patient lying on the bed fell off the bed and inadvertently activated the foot control to move the mattress platform down and injured the patient's area. Protection against accidental activation of the foot controls the switches placed on them are either not used at all for some types of hospital beds or are used in the form of covers above fixed-foot foot switches to retract the operator's foot. This gap must be large enough to allow the operator's foot to retract. However, this large gap offers only limited protection against accidental contact with the foot switches.

The essence of the technical solution

These disadvantages are overcome by the hospital bed foot controller according to the present invention. The foot actuator comprises a base member and at least one foot switch located thereon. The essence of the invention is that at least above a part of the foot switch there is a protective element that prevents accidental activation of the foot switch. A gap is formed between the foot switch and the security element, which is mounted on the foundation part tilting by less than 90 [deg.], The height of which is dependent on the tilting of the cover element, where the gap height is minimal. This minimum gap prevents the foot switch from being actuated by simply inserting the foot tip onto the foot switch.

Advantageously, a first stop is provided between the security element and the base to define a minimum gap height. With the first stop it is possible to adjust the minimum height of the leg for insertion as required.

Another variant of the foot control solution is characterized in that the security element is provided with a second stop, which can define the maximum angle of the security element tilting and thus ensure a reliable movement of the security element back to the basic position.

The foot control is simple to manufacture, in which the protective element returns to the basic position by its own weight when the foot is moved out of the gap.

The foot actuator may be provided with a protective element which returns to the initial position after the foot is forced out of the gap by means of a compression or tension spring. The use of springs ensures a reliable return of the security element to the initial position, that is, when there is a minimum gap between the security element and the base member, preventing the foot from sliding over the foot switch and activating it. A preferred embodiment of the foot controller has a protective element in the form of a protective yoke.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a foot actuator according to the invention in an axonometric view. FIG. 2 is a cross-sectional view of the foot switch.

Examples

1 and 2 there is shown a foot actuator formed by a base part 4 on which the foot switches I are mounted. The protective element 2 shown to prevent accidental activation of the foot switch 1 is in the form of a protective calliper. As can be seen from both Figures, a gap 6 is formed between the foot switch I and the protective element 2, which is hinged on the base part 4 by an angle of less than 90 °, the size of which is dependent on the tilting of the protective element 2. Fig. 2 shows, in the basic, non-open position of the security element 2, the height of the gap 6 is minimal, thus preventing the toe from sliding over the foot switch I and thereby undesired activation of the foot switch 1.

When operating the foot switch I, it is necessary to first lift the protective bracket with the toe of the foot, and then to press any foot switch 1 with your foot. In order to increase the reliability of the foot actuator, it can be provided with a compression or tension spring which ensures a reliable return of the folded-off security element 2 to its initial position. Excessive folding of the caliper is prevented by the first stop 3. This two-phase manipulation when actuating the foot switches I, i.e. the need to lift the protective element 2 first, in the illustrated example of the yokes, feet and then the foot switch I, is assured. The foot switches will not be activated.

Industrial applicability

The technical solution is primarily applicable to beds where the shaping of their loading surfaces is carried out using electric servomotors. These are mainly beds for hospitals, for standard inpatient wards and for residents in nursing homes, social care institutions and other facilities for social and senior care, or for home patient care.

Claims (6)
