Description

The The invention relates to an access arrangement for rooms for in particular medical treatments, with a radiation protection door, which release or close a door opening can, with a first, outer surface area a floor adjacent to the door opening outside the room for the particular medical Purposes, with a second, inner surface area of a Floor adjacent to the door opening inside the room for the particular medical purposes, with a Control device for the control of the opening and / or closing movement of the radiation protection door, and at least one user-operable one Actuator connected to the control device is

In Rooms for medical treatments will be in many uses radioactive and other radiations, For example, X-rays, gamma rays, particle radiation from high-energy reactions or irradiations from frames of Cancer therapies and the like. It is of considerable interest the radiation from these rooms does not go outside to let in, there to an uncontrolled radiation exposure other patients and also the medical staff respectively.

For this reason, much attention is paid to the walls of these treatment rooms. For example, the DE 103 27 466 A1 a structure for a corresponding radiation protection structure, which is constructed in a sandwich construction of several layers of concrete. Between several concrete layers further radiation protection materials are embedded.

Similarly, the DE 10 2004 052 158 A1 likewise radiation shielding layers in corresponding structures.

One Weak point in the shielding of the corresponding radiation the entrances, which can be closed with radiation protection doors are. These radiation protection doors become self-evident needed, so that the rooms on the one hand by the On the other hand by the medical staff and can be left again, on the other hand it is important that just these radiation protection doors as well the remaining walls of the treatment room the radiation as completely as possible. The radiation protection doors must therefore in any Shape to be kept movable.

For shielding in the radiation protection doors, these are often filled with lead plates inside. Alternatively, for example, in the DE 36 22 659 A1 and the DE 103 14 855 A1 Radiation protection doors proposed that are filled with a heavy concrete filling. The DE 103 14 855 A1 suggests, for example, the use of barite (BaSO ₄ ), hematite (Fe ₂ O ₃ ) or magnetite (Fe ₃ O ₄ ) and recommends the most homogeneous possible filling of the door leaf with the cast heavy concrete.

Both Solutions lead to radiation protection doors, which can be 20 to 30 tons. There is Such radiation doors as well as sliding gates also as swing gates.

Around to move such heavy radiation doors, motor drives are used, which are the radiation protection doors either in front of a door opening wall parallel can push or a swing or turn about a hinge axis adjacent to the door opening can make.

by virtue of their function as radiation protection doors is thereby the case Closing to a radiation-tight closure of Door opening on. The motor drives are so accordingly strong, even with the heavy weights to be able to afford.

is Such a relatively heavy hinged door or revolving door has been set in motion by the motor drive, so needed they have a definite, by no means negligible Braking distance until stop. For the radiation-proof closing This is not critical, because this can be controlled cleanly.

Very However, this is problematic when looking at body parts like an arm or a hand in the path of the radiation protection door located. It is practically impossible with physical strength to stop the heavy radiation protection door. Arrive therefore a body part such as an arm or a hand in the area between a closing radiation protection door and the adjacent wall, this can cause serious injury and lead to the loss of appropriate body parts.

Conventional safety shutdowns, as they are known from elevators or public transport, work with contact sensors in the moving elevator doors and hold the elevator door when recognizing such a contact. However, such solutions are useless in the radiation protection doors to be considered here. If such a sensor recognizes the contact, it is already too late and the movement of the radiation protection door can no longer be sufficiently slowed down, so that it leads to the mentioned injuries despite this recognition comes.

It is therefore traditionally required, the door openings to be secured by accompanying personnel, such as when a patient is led into the treatment room.

This is very prone to errors and beyond also unfavorable, as the medical attendants themselves especially to the patient before the treatment, for example the irradiation, and, moreover, the attention of those accompanying staff due to the weakness or the disease to be treated Of course, the patient also claimed and not by technical ancillary services like monitoring a door opening should be distracted.

After all is also to be considered that about revolving doors or swing doors also an opening Door covers a certain surface area and because of its considerable weight, one in this area cause serious injury to a standing or walking person can if they are unexpectedly hit by the radiation protection door becomes. Again, it should be noted that in this Area often patients of a hospital or one Doctors who are not particularly attentive, yet physically particularly resistant.

It There is therefore a desire for access arrangements for rooms for in particular medical treatments that have a larger Safety for the users and the patients to be treated Offer.

It An object of the invention is to propose such an access arrangement.

These Task is inventively in a generic Access arrangement achieved in that at least one of the two Floor areas of the floor adjacent to the door opening with Pressure sensors is equipped that the pressure sensors of the two Surface areas of the floor adjacent to the door opening equipped with pressure sensors is that the pressure sensors with the control device connected so that they exerted on the pressure sensors Report pressure to the controller, that the control device is designed so that in case of a notified her pressure on the pressure sensors, the opening and / or closing movement the radiation protection door stops, and that the controls adjoining outside the surface areas of the floor are arranged to the door opening.

With This conception can be achieved that without additional Measures by escorts and even without escorts significantly improved safety when using radiation protection doors entry.

The fundamental idea is based on the surfaces of the floor in front of the door opening and possibly also inside the door opening and on the inside of the room for the medical treatments equipped with pressure sensors. This can be done in preferred floor mats according to preferred embodiments be.

such Floor mats that can make electrical contacts, can work very reliably.

According to the invention now be provided that in the moment where such a pressure sensor or such floor mat determines contact or entry, a corresponding signal is given to the control device of the radiation protection door and this causes a moving door immediately stops.

Different as comes in the conventional elevator doors It is no longer important to have contact with the Door itself enters, but the stop is already then prompted, if only the remote possibility is that a person or, for example, a hospital bed comes near the radiation protection door and at a continued movement of the person, the bedside or maybe also the radiation protection door it to a contact between them, with those already discussed Injury.

signals a pressure sensor or the floor mat such Pressure or contact, not just a moving door Immediately stopped, but also sets a still-standing door not moving anymore.

It may also be provided in some embodiments, that is an already moving or closed door is moved back into the Auffahrstellung. This is not desired in every embodiment, however, it may be taken into account as appropriate.

Are located So people near the radiation protection door, This can not move or stop a movement.

Opening or also closing the radiation protection door for an intended treatment or even after leaving the treatment room can nevertheless be given by a corresponding actuating device. This actuator may be about a switch, the located at a suitable distance from the radiation protection door outside of the areas that is equipped with the pressure sensors. For example, if a previously locked room to be entered, this actuator is initially actuated at a corresponding distance from the radiation protection door, then waiting for the opening process of the radiation protection door, such as a swing and then can be entered through the door opening of the room. If, due to carelessness or negligence or in ignorance, a patient or accompanying person enters the area in front of the radiation protection door before the end of the opening process, the opening process is interrupted immediately and any risk of injury is ruled out.

Prefers it is when the surface areas of the floor, in which the pressure sensors or floor mats are arranged accordingly are optically marked. This is suitable, for example a corresponding coloring.

The On the one hand, the measure has the advantage that the users are warned and to be informed which area they should not enter to the opening or closing process of the radiation protection door not to be affected; At the same time, this would be without the Invention also a corresponding danger area, what the understanding the measure for the groups of people involved very relieved.

A Labeling or in particular coloring of the corresponding Floor areas of the floor also have the advantage to simplify later maintenance or repair work. Should be rebuilt about the area or are repairs to the Pressure sensors or floor mats is immediately clear which area of the floor will be processed accordingly got to.

It it is not necessary that those equipped with the pressure sensors Mats form the top layer of the floor itself. This has the advantage that these floor mats are slightly in one area can be embedded below the surface. This allows a completely flat and even surface of the floor to be achieved, what for driving and entering the appropriate aisles is beneficial, there for the patient and also for the staff no differences, levels or increases and, for example, also a hospital bed easily in the room for the medical Treatments can be driven without bumps and bumps to be rolled.

It So is the flatness of the surface by the invention not impaired. Especially in these cases is a marking or coloring of the surface makes sense, as there are no other clues for the user group exist more.

in the The following is an exemplary embodiment with reference to the drawings the invention explained in more detail. It shows:

1 a plan view of a schematic representation of the access area of a room for particular medical treatments, which is designed according to the invention.

A room 10 serves for medical treatments. In the room 10 there is a radiation source 11 , the Rays 12 emits. These rays 12 serve to treat, for example, a patient 13 ,

The Rays 12 the radiation source 11 are dangerous or at least detrimental to people who are not to be irradiated and treated. These people 14 are therefore outside the room 10 , The space 10 is therefore with a wall 15 provided that shields the rays.

The access to the room 10 is formed by an opening, which has a radiation protection door 20 is closable.

The radiation protection door 20 In the illustrated embodiment, a sliding gate, which can be moved so that it releases the opening or closes in the case of treatment, so if the radiation source 11 Radiation to the patient 13 sending out.

The floor near the radiation protection door 20 has a first surface area 21 and a second area 22 on. The surface area 21 is outside the treatment room 10 and so on a corridor or a hospital or in a doctor's office. It is the surface area 21 , directly to the radiation protection door 20 borders.

The second area 22 is inside the room 10 also in the to the radiation protection door 20 adjacent environment.

The surface areas 21 and 22 and also the floor immediately below the radiation protection door 20 when closed, those areas are those in which there is a risk that one on these surface areas 21 . 22 standing, walking or otherwise located person with a moving in the opening or closing direction radiation protection door 20 comes into contact.

The radiation protection door 20 could also be an embodiment not shown Swing door or revolving door. Then, for the area area 21 or 22 also takes account of that area which is swept by the radiation protection door during pivoting, plus another area where there is a risk that persons walking there or moving themselves may enter this pivotal area in the near future.

For the size and area dimensions of the surface areas 21 and 22 can also change the speed of movement of the radiation protection door 20 be taken into account.

These surface areas 21 and 22 are highlighted in the illustrated embodiment and may include pressure sensors approximately in the form of embedded in the floor floor mats. These pressure sensors or floor mats are in data communication with a controller 30 , which is shown here purely schematically. The control device 30 controls the opening and closing movements of the radiation protection door, and thus stands, among other things, with the motor drive of the radiation protection door 20 in connection.

The Pressure sensors detect the stress that is placed on the surface area standing or walking person or even an object due to Gravity on the floor.

There are also controls 31 and 32 which here in the form of switches on the one hand outside the room 10 and then inside the room 10 are indicated. These controls 31 and 32 are arranged so that they only from outside the surface areas 21 . 22 can be operated.

These controls 31 . 32 can not only be switches, it is also possible remote controls or can be controlled by signalers of the accompanying staff of patients or by optical or other detection options and operated.

Also these controls 31 . 32 stand with the control device 30 in connection.

The control device 30 So receives on the one hand signals from the controls 31 and 32 that the control device 30 can cause the motor drive of the radiation protection door 20 for the purpose of opening and closing, on the other hand, they also receive signals from the pressure sensors in the surface areas 21 and 22 , which stop the motor drive at a signal by pressure occurring or prevent it despite actuation of the actuator 31 and 32 starts.

To think about is also the case, that about a panning a person from the inside of the room 10 from the actuator 32 pressed and the radiation protection door 20 Therefore, although in the area 21 in front of the radiation protection door 20 outside the room 10 another person, a hospital bed or other is located. This is also avoided by the invention.
