Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to patient reclining chairs for use by patients undergoing treatment.

[0002]

During certain treatments, especially extracorporeal blood treatments, the patient being treated must remain stationary. In such cases, it is common practice to utilize patient reclining chairs that offer greater comfort than, for example, standard chairs. In these patient recliners, the patient reclining surface is usually
It is adjusted to allow the patient to assume a reasonably comfortable sitting / reclining position during extracorporeal blood treatment. For example, hemodialysis treatment can last several hours. In addition, during extracorporeal blood treatments where the blood circulation of the patient is inherently stressed, this type of reclining chair allows the patient to be positioned in a way that the blood circulation is less sensitive.

German Patent No. 299 15 914 U1 discloses a therapeutic recliner chair having a patient reclining surface divided into three areas, at least one area stimulating the blood circulation of the patient. It includes an element for generating vibrations.

[0004]

The patient reclining chairs and devices for extracorporeal blood treatment according to the state of the art have the disadvantage that they constitute a separate element. When it is necessary to change the position of the patient on the reclining chair or, if applicable, to move the equipment with the patient being treated.
It is troublesome to move the blood treatment apparatus and the patient reclining chair at the same time. Often, no one person can make this move. Discontinuing treatment due to tedious transfer and accidental treatment urgency is highly undesirable, especially when the patient is undergoing extracorporeal blood therapy.

It is an object of the present invention to develop a patient reclining chair which simplifies handling during extracorporeal blood treatment and yet allows greater flexibility.

[0006]

According to the invention, this object is achieved by the features disclosed in the characterizing part of claim 1 of the claims. The modified embodiment of the present invention constitutes the invention of the dependent claim of claim 1.

The patient reclining chair according to the present invention eliminates the problems caused by the separate recliner chair and blood treatment device by incorporating the blood treatment device into the reclining chair. These two
If one device needs to be moved to another location, these two devices are always moved at the same time. in addition,
Such a patient reclining chair reduces the required space. This is advantageous as a unique application of the patient reclining chair of the present invention in clinical or home applications. Various areas of the patient recliner are used to house extracorporeal blood treatment devices or parts thereof. The space below and / or behind the patient reclining surface typically remains unused.
The armrest as well as the reclining surface itself is also used for installation purposes.

It is also conceivable to connect the blood treatment device or parts thereof to the reclining chair by means of a pivoting mechanism. In another embodiment, an insertion mechanism is used to attach the blood treatment device to the reclining chair. In these embodiments, the corresponding parts can be easily replaced.

According to one advantageous embodiment of the invention,
The patient reclining surfaces are pivoted relative to each other 3
Has one segment.

In one embodiment of the present invention, the blood treatment device is divided into a patient dependent module and a patient independent module. These modules are mounted at different points on the patient reclining chair. Supply module,
That is, heavy components such as power packs, batteries, or fluid preparation units may be housed below the reclining surface as a patient independent module. Extracorporeal blood circulation elements, i.e. patient dependent elements, are, for example:
It may be housed in a patient dependent module as close as possible to the patient by a pivoting and / or telescoping mechanism. In this case, it will be appreciated that the extracorporeal blood circulation blood line extending between the blood treatment unit and the patient may be very short. This makes it possible to keep the extracorporeal blood volume as well as the amount of anticoagulant to be administered relatively low. In addition, other interfering variables (eg, heat loss) are minimized. The two modules are connected to the necessary connection lines (eg for media, power supply, data exchange).

In another embodiment of the invention, the blood treatment device comprises a hemodialysis device. This collective term also applies to artificial kidneys based on the principle of dialysis, filtration or a combination thereof. In one variation of this embodiment, a hemodialysis machine is a patient independent module consisting of a patient dependent module consisting of a blood treatment module for dialysis treatment and a hydraulic module for preparing and balancing or averaging dialysis fluid. It is divided into modules and. These modules are
Mounted at different points on the patient recliner.

Another embodiment of the invention has an actuator on the patient reclining surface. For example, a heating surface may be placed on the patient reclining surface where the patient undergoes chilling during extracorporeal blood therapy due to the excessive coldness of the dialysis fluid during dialysis therapy. The onset of such symptoms may be initiated by the hemodialysis machine using cold dialysis fluid, if applicable, to stabilize the blood circulation in a targeted manner.

It is also possible to provide an adjusting element for positioning the reclining surface of the patient. In this case, the reclining surface is preferably adjusted to be motor driven.

In another embodiment of the present invention, the blood treatment apparatus is connected to an actuator, and the actuator is directly controlled by the blood treatment apparatus. As a result, the blood treatment device constitutes a user interface that enables central data entry. In certain cases, the blood treatment device, if applicable, by evaluation of the sensor value,
It is also conceivable to control the actuator autonomously.
For example, if hypotonic blood pressure is detected by the blood pressure sensor, the patient reclining surface may be automatically adjusted to move the patient to the shocked position.

The flexibility of the patient reclining chair according to the invention is additionally improved in various ways. For example,
The beverage holder, meal table, massage pad and voice-oriented control device can contribute to the flexible use of the patient reclining chair.

Additional details and advantages of the invention will be explained in more detail with reference to the embodiments shown in the drawings.
