       [0002]    The present invention relates to devices for preventing fatal bathroom accidents. Particularly, the present invention relates to devices for preventing fatal bathroom accidents relating to falls and/or drowning. 
       BACKGROUND OF THE INVENTION 
       [0003]    The present generation of elderly people remains more active than ever. Rather than moving into specially observed homes and retirement homes, they regard their own homes, having lived there for a long time, the ideal place to live after retirement and arrange themselves accordingly; this is a generational change that has happened only within the last 15 to 25 years. Before then, retirees usually considered moving to a retirement home or a living facility at a much earlier age than nowadays. Presently, retirement homes are used more to help those with pressing diseases such as dementia or other ailments requiring around-the-clock care. 
         [0004]    Most accidents happen at home. Especially accidents in bathrooms bear a high risk of fatal injuries due to slippery surfaces and a lack of protecting clothes. For example, elderly people may faint while taking a bath. If the fainted person is not able to wake up in time, it may drown in the bath tub. Another common accident is slipping in the shower which may lead to bone fractures or similar injuries. 
         [0005]    Accordingly, there is a need for safety methods and equipment to prevent fatal injuries in the bathroom, especially for elderly people or other susceptible persons (e.g. persons suffering from epilepsy). 
         [0006]    Amongst the ageing and those with multiple sclerosis or epilepsy, drowning in a bathtub is a common cause of death. Once a person faints in the bath tub, the body slides down until the head is under the water surface; if he or she does not recover consciousness, drowning occurs in less than 3 minutes. 
         [0007]    The present invention uses the movement of the fainting body to increase the chances of survival by making the water flow out of the tub. 
         [0008]    Furthermore, slipping in showers is a known, but little researched cause of severe injuries and death amongst the elderly. The leading injuries sustained in a fall in the shower are:
       broken upper leg bones   broken hips   broken lower leg bones, in particular the shin   concussions   spinal injuries   broken noses, fingers and hands, and   fractured skull.       
 
         [0016]    While some injuries heal, others have serious complications. For example, a broken hip of an already weak person can entail such demanding surgery that the operation might result in death. 
         [0017]    The present invention is not trying to hinder the fall. Though attempts have been made, primarily within the American medical community, fall prevention efforts have been unsuccessful. A fall can have several causes-all of which cannot be helped by adding more handles to the shower or installing anti-skid mats. Particularly senior citizens may suddenly feel a loss in the leg muscles (“weak knees”), experience dizziness, and slip while showering; here neither the anti-skid mat nor the handles help, as the center of gravity is constantly changing when one showers. 
         [0018]    The most perfect protection would either include a chair in the shower or wearing a belt, structured like in a parachute. However, the latter is not only uncomfortable, but difficult to put on; the areas where the belt is strapped to make it impossible to clean the underlying skin. Though the shower chair is commonly used by people unable to stand, it still remains an uncomfortable alternative. Slipping still occurs when exiting the shower, once the chair starts to move around, or when the body is covered with soap and water.

     DETAILED DESCRIPTION OF THE INVENTION 
     1: Device Against Drowning in Bathroom Tubs—Manual Version 
       [0041]      FIG. 1  is a schematic diagram of a bath plug device according to a preferred embodiment of the present invention. According to  FIG. 1 , a cone  20  is used attached to the top of the bath plug  10 , at least one pedal-like unit  30  (preferably two units as shown in  FIG. 1 ) to the left and/or to the right of the cone  20  are attached, covering more or less the whole span of the bath tub. The user is supposed to have his feet not on the side of the cone, but closer to his own body, preferably by lifting his knees slightly. 
         [0042]    Once the user becomes unconscious, the body moves down along the bath tub, the feet pushing against the pedals  30  or the cone  20  itself This moves the cone  20  away from the user and lifts the bath plug  10 , allowing the water to flow out. In one embodiment, the bath plug device has an overall density which is slightly below the density of water (e.g. by choice of material of the bath plug formed cavities in the plug that contain air) such that the bath plug device starts to float as soon it is detached from the pipe. Thus, the bath plug  10  will not return to a pipe closing state once it is detached such that drain off of the bath tub water is not disturbed. 
         [0043]    With the lowering of the water level, the chance of survival increases dramatically. It is then only a matter of the speed of the water flowing out and the time needed for the bath tub to drain. This can be calculated by the diameter of the pipe and the water level. 
       2: Bathroom Tub Drowning—Electric Version 
       [0044]    In an electric version (not shown), the cone  20  is placed on top of the draining pipe. However, the bath plug  10  resides in the cone  20 , the plug being connected with a fixed wire to either an electric motor or a compressed air tube and a tilt sensor, e.g. a girometer fixed inside the cone  20 , which in turn are wirelessly connected to a bath security switch and/or a house server providing safety services like software that may trigger an alert at official services (a call center, police, ambulance, fire department etc.). On the side of the cone  20 , between the plug  10  and the motor or tube, the cone  20  has an opening. In the fully retracted mode, the plug is above the opening. 
         [0045]    Once the bathroom switch is pressed, this information is transmitted to the cone  20 , causing the electric motor or compressed air tube to lift the plug over the opening. This causes water to enter the cone  20  and flow through the now-open drain pipe, thus lowering the water level. 
         [0046]    The pedals  30  described earlier can potentially be attached to the electric embodiment of the cone  20  as well. 
         [0047]    If the cone  20  is pressed down, the embedded girometer can trigger the upward movement of the motor or tube, and send a distress signal to the bathroom security switch and/or the house server such that further safety services are informed. E.g. a call center operator may first be allowed to communicate to the user in the bathroom and, if the user does not react, pictures or even a video signals may be transmitted to the operator. However, other safety means, like informing neighbors, residents of the home, or nearby relatives (“first responders”), may be triggered in addition or as an alternative. Such information may be provided via software on mobile phones of the respective first responders. Such measures (i.e. who should be informed in what case) may be selected by the user beforehand. 
       3: Shower Fall Prevention 
       [0048]      FIG. 2  is a schematic diagram of a shower fall prevention device according to a first preferred embodiment of the present invention.  FIG. 3  is a perspective view diagram of a shower fall prevention device according to the first preferred embodiment of the present invention. The present invention has been made to give ease of movement. Normally, the structure does not require contact with the skin. 
       Hardware 
       [0049]    A rod  100 , preferably made from iron or stainless steel, described is fixed to the ceiling near the center of the shower ceiling either by a strong rubber band (not shown) with very little leeway or preferably—for user comfort—by an extendable and retractable belt  110  is rolled up in a box  112  similar to a safety belt retraction unit. If the unit is attached to a bath room, it will be placed on the ceiling, vertically aligned to where the person usually stands while showering. 
         [0050]    To the left side of the rod  100 , a handle  200  is attached. An solid part  300  is bent down from the handle  200 , then backwards in a half circle, then up again, from there in a straight or slightly curved line (indicated in  FIG. 3 ) to the right side, where it bends down again in a half circle. The solid part  300  is fixed to the rod  100  at or near the middle of the straight or slightly curved part. 
         [0051]    Said straight or slightly curved part is extendable and retractable, e.g. by a telescopic mechanism in the rod, as an example but not limited to a expansion plug telescopic rod or other suitable detent mechanisms. The solid part  300  is bent up again, then to the left to about one half of the full width of the unit. At that point a small, soft cushion  400  is placed; in a preferred version of the unit, this cushion  400  can be moved upwards and to the side and may be locked in a position by a suitable locking mechanism. The cushion  400  is provided to prevent injuries of face and head of a user slipping in the shower and falling forward towards the shower wall (not shown). 
         [0052]    For more comfort the rod  300  can have a full cushion (not shown) placed around the whole area, in particular where the armpits would fall. In an alternative version, shower walls can be covered with a delta-shaped cushion (not shown), in which the long side of the triangle is attached to the wall, the shortest side under the longer side of the cushion triangle. 
         [0053]      FIG. 4  is a schematic diagram of a shower fall prevention device according to a second preferred embodiment of the present invention. Basically, the embodiment of  FIG. 4  corresponds to the embodiment shown in  FIGS. 2 and 3 . The difference between said embodiments is the manner in which the rod  100 ′ of  FIG. 4  is fixed. Rod  101 ′ does not have a fixing to a flexible member like in  FIGS. 2 and 3  (belt  112 ) but instead comprises one or more solid rods  100 ′ fixed to fixing points somewhere in the shower. E.g. rod  100 ′ may be fixed directly to a shower tub or to walls surrounding the shower. Number and stability of rods  100 ′ are chosen such that the device provides enough stability to support a falling person. Care should be taken to not place the rods  100 ′ such that the user is hindered at entering and leaving the shower. 
       Method of Use 
       [0054]    The user enters the shower and moves his body through the opening in front of the fall prevention unit, so that the straight or slightly bent part is close to his back, running from shoulder to shoulder. He puts his left arm through the left part, his left armpit over the unit&#39;s left half circle; his left hand grabs the handle  200  on his left side. He then stretches his right arm over the right half circle. He moves the unit on the back below his shoulders and extends or retracts the unit to a comfortable width, then places the soft cushion  400  in front and near his head. 
         [0055]    Once the user has put on the solid part of the mechanism, he or she may move freely inside the shower, only obeying that the left and right curves stay below the shoulders. 
       Functionality 
       [0056]    In the case of a fall, the body of the user moves downward and/or forward. The forward movement is stopped on the left side by the solid piece with the handle  200  and in the middle by the cushion  400  near the face; this cushion stabilizes the head in the case in the case of a severe fall. The person slides down, having the fall stopped when the armpit falls in the downward half circles. 
         [0057]    Then, the fall is stopped either by the rubber band (not shown) or by the lock of within the belt retraction unit  112 . 
         [0058]    The cushion on the wall (described above; not shown) would in severe cases cushion the back of the head against the wall; by placing the second-longest side on top, the head can slide down over the cushion, not having to move over a top or bottom step, which might cause additional head injuries. 
       Connection to a Home Security Unit 
       [0059]    In a preferred version of the invention, a switch with a wireless connection and battery is attached to the belt  110  or the retraction unit  112 . Once the impact is transmitted to the rubber band or the retraction unit locks, the switch sends a signal to either the remote server directly or to the bathroom switch unit, which uses this signal as if the alarm has been triggered. 
         [0060]    The switch can also be integrated into the cushion  400  so that a strong push against the cushion triggers the alarm.
