It has supports (6') formed into levers on opposite sides of the care bed, moving through a rotation angle (alpha). A transmission mechanism (17) transmits to a shaft (18). The shaft by means of a lever and a draw and pressure cable (20) operates the coupling (21) of the back rest, so that everything occurs in one movement and when the rapid lowering device is released the coupling is directly blocked.

Description

- 1 - IMPROVED QUICK-DOWN DEVICE FOR THE BACKREST OF AN ADJUSTABLE NURSE BED.

The invention relates to a device for rapidly lowering the back support of a nursing bed, which is designed for the stay, nursing, treatment and transport of patients in a hospital environment, wherein the rapid fall is intended to prevent the emergence of an emergency (e.g. resuscitation). be able to level the backrest flat in a few seconds, whereby the rapid fall can be activated by pressing down or pushing a quick-fall lever at the head end of said nursing bed, after which said backrest can then be lowered by hand and when the quick-fall lever is relocated When released, the position of the backrest is automatically locked, whereby the normal bed settings are made by the patient or nurse by means of a remote control by an electric motor with a battery and coupling to movement axes, etc., with said rapid-fall lever actually only the coupling being operable, whereby said fast pushing down back support is possible.

The aforementioned nursing beds with foldable or hinged back support, which in nursing homes must be provided with a rapid-descending device, are known. For example, the present applicant has the Pronto Model 101 nursing bed that she has placed on the market and that meets high requirements. The lying part here consists of a number of plate-shaped parts which are hinged relative to each other and can be brought at an angle to each other, so that almost any desired lying profile can be realized for the patient to be treated. The whole is with a remote control by the patient by means of an electric motor, which is connected by means of a coupling to all kinds of mechanisms to achieve the desired lying profile, as can be read on the remote control. This concerns matters such as backrest angle (0 ° to 59 °), maximum auto contour ratio 98 °, Fowler f '! U *. ·· - '' ^ - 2 - angle (upper leg / lower leg) of 24 ° and the like. The bed has a safe working load of approximately 200 kg, a total achievable length of 218 cm and a width of 100 cm. The accompanying mattress size is 88/198/14 cm and the highest / lowest 5 position is 86/43 cm. The electric motor is thereby powered by a battery, which can be charged with a connection voltage of 230 V alternating current with a power consumption of 198 VA. The battery must be charged approximately every 6 months. Furthermore, the nursing bed is provided with 10 castors, so that the patient with the nursing bed can easily be moved along the corridors of the hospital or nursing home. The upper part of the head end of the nursing bed, the so-called back part or the back support, must be able to be lowered quickly in a horizontal position in an emergency in a few seconds. For this purpose a handle is positioned behind the head end, which lever operates a clutch.

By operating this lever, the backrest can be pushed directly downwards.

There are drawbacks to this known system because the handle is located behind the head end of the nursing bed and the nurse or doctor must operate the handle behind the head end and / or another nurse has to press the back part down, which is cumbersome and therefore time-consuming and is disadvantageous in emergency situations, because valuable time can then be lost and this will often also happen.

The object of the present invention is to provide an improved quick-fall device for the backrest of a nursing bed which does not have the disadvantages described above and whose operation is better at an economically justified cost price when applying to a nursing bed.

To this end, a device for rapidly descending the back support of a nursing bed has been developed in a very inventive manner such that a specific rapid-fall lever is provided on both longitudinal sides of the nursing bed on the edge profiles of said back support, which

O

Of a transmission mechanism operates an axis at the extreme profile of the back support, which axis, in turn, operates a flexible connection in the form of a tension and pressure cable connected to the coupling with the lever connected thereto, the The materials selected for the various components and their protection are selected in such a way that they comply with the applicable medical device guidelines.

The advantage is that promptly or directly at the patient's head 10 the supporting back part of the nursing bed can fall into the horizontal position within one second. Thus, the operation of the lever and the pressing down of the back part starts in one operation and can take place from both sides of the nursing bed.

Furthermore, the device according to the invention is further developed such that said specific fast-lowering lever as a lever with a spherical end knob forms a whole with the inverted U-shaped element, which again or also acts as a lever and is coupled to said transmission mechanism , wherein said spherical end button is made of plastic and is attached to the lever by means of a threaded connection, the color of the spherical end button being red.

The advantages are a clearly recognizable system, which, when properly maintained, cannot malfunction and is always immediately within reach.

The device according to the invention is then further developed such that said pull and pressure cable is of the type inner / outer cable, which is fixed at the ends 30 to a strip or to said coupling, preferably by means of a threaded connection, wherein said pull and push cable as inner cable consists of a composite wire.

The advantages are an extremely flexible transmission 35 for decoupling, which can be built into any bed without problems regardless of where the coupling is mounted.

The whole is also great to order afterwards to always function optimally 1 0 1 '<7> 3 - 4 -.

The invention is explained in more detail below with reference to a preferred embodiment shown in the drawing. Herein: figure 1 shows in oblique projection and in perspective an adjustable nursing bed, in which the improved quick-fall device for the backrest can be incorporated in accordance with a preferred embodiment of the invention; and Figure 2 shows the rapid-fall device mounted in the backrest of a nursing bed according to a preferred embodiment of the invention in oblique projection.

Figure 1 shows a nursing bed 1 in oblique projection and in perspective 15, into which the improved quick-fall device for the backrest 2 according to the invention of Figure 2 can be built in. The mattress supporting supports 2, 3, 4, 5 can form an angle with respect to each other, so that the support of the patient is fully adjustable. Furthermore, the nursing bed 1 has lateral mattress supports 6 and 6 ', wherein the supports 6' are modified and made usable for use as a lever 7 (Figure 2) for the improved rapid-fall device 8 according to the invention. The bed limiters 9 are adjustable in the vertical sense. The board 10 at the foot end is extendable to make the nursing bed 1 longer to approximately 2.18 m. At the bottom of the board 11 on the outside, according to the state of the art, the levers for releasing the coupling are located. In the rapid-fall device 30 according to the present invention, the levers 8 are located on the supports 6 'which have been extended to the lever extension, i.e. directly on the back support 2 and on both sides. Furthermore, the nursing bed 1 can be moved up and down according to arrows A and B by the motor-operated scissor mechanism 12, which in turn is mounted in the frame 13 with the swivel wheels 14.

The actual invention is shown in Figure 2.
