This invention relates to anchors for patient restraint devices. One or more restraint assemblies may be incorporated into a medical bed to improve patient safety and reduce risk of injury, while simultaneously improving flexibility and the ease of connection and disconnection of patient restraint devices during use.
Patient restraint devices frequently include straps which are used to limit mobility in cases where a patient/individual may pose a danger to themselves or others. The patient restraint devices are used with the utmost concern for patient safety and employ every conceivable feature to avoid causing additional injury to ligature, muscle, bones or other bodily portions or organs of a patient. Patient restraint devices may be used in surgical applications, to limit movement following a medical procedure or in situations where the mobility of a patient/individual is required to be restricted to insure the safety to the patient/individual or to others including medical staff.
A patient restraint devices may be used to maintain a proper bodily position during a medical procedure. Alternatively, a patient may need their arms to be restrained to ensure that tubes and catheters are not removed which are providing critical medicine and fluids. Some restless or confused patients require restraints to prevent the patient from getting out of bed before recovery or reducing the chance of falling and injury. Restraints are also utilized for patients being transported on stretchers to diminish the risk of falling off the stretcher. Patient restraints may also be used in psychiatric settings to prevent patients from harming themselves or others.
In the past, patient restraint devices have been anchored to various locations proximate to a medical bed including the bed rails and adjacent walls. The use of the known anchor locations was frequently problematic and required excessive time to secure an individual into a desired position.
In the past, patient restraint devices have not included components which may be easily and quickly assembled together, in order to provide a desired secure position for a patient/individual. In addition, the known patient restraint devices have not provided the flexibility to be easily disassembled, enabling relocation of a patient/individual to an alternative site or position.
Further, in the past, patient restraint devices have not included a locking feature to reduce risk of inadvertent separation of a patient restraint device from an anchor during use of the patient restraint device.

In some embodiments, the vertical slot 20 has a height dimension of 1 inch and a width dimension of ½ inch. In other embodiments, the height dimension for the vertical slot 20 may be more or less than 1 inch, and the width dimension may be more or less than ½ inch. In at least one embodiment, the vertical slot 20 includes an arcuate or rounded edge at the top and/or bottom of the vertical slot 20.
The restraint assembly 10 additionally includes an adapter buckle 14. The adapter buckle 14 includes an exterior section 24 which in use is disposed proximate to the front 16 of the mounting plate 12. Likewise during use, the interior section 26 is disposed proximate to the rear 18 of the mounting plate 12 within the opening 54. The adapter buckle 14 is coupled to the mounting plate 12 during use of the restraint assembly 10.
In at least one embodiment, the exterior section 24 includes a rectangular head 28. It should be noted that any desired shape may be selected for the head 28 dependent on the requirements of a particular application. The head 28 is integral to an arm 30. The arm 30 descends from the central section of the lower edge of the head 28. The head 28 and arm 30 are preferably integral with each other and are formed of a single portion of stainless steel material.
The head 28 includes a horizontal slot 46 which is centrally positioned and oriented horizontally within the interior of the head 28. The horizontal slot 46 is generally used to releasably receive straps of a patient restraint device. Generally, at least one strap of the patient restraint device is looped through the horizontal slot 46. The at least one strap of the patient restraint device may then be secured to the strap or to an adjustable restraint buckle for tightening or loosening to provide a desired tension relative to the medical bed.
It should be noted that the restraint assembly 10, mounting plate 12, and the adapter buckle 14 function as an anchor on a medical bed during use of a patient restraint device.
In at least one embodiment, the arm 30 extends from the head 28 to the stop 34 which may be “T” shaped. The arm 30, and head 28 as well as the stop 34 are preferably formed of a single piece of stainless steel material.
The arm 30 as previously identified extends outwardly and downwardly from the central portion of the lower edge of the head 28. The arm 30 also extends upwardly from the central portion of the upper edge of the stop 34.
In at least one embodiment, the arm 30 at the approximate midpoint between the head 28 and the stop 34 includes an angular bend 32. The angular bend 32 is approximately 145° creating an angle between the head 28 and the stop 34 of approximately 145° or 35° upwardly from a horizontal plane relative to the stop 34.
In at least one embodiment, the angular bend 32 is the dividing area of the adapter buckle 14 between the exterior section 24 and the interior section 26. The portion of the adapter buckle 14 between the angular bend 32 and the head 28 is the exterior section 24. The portion of the adapter buckle 14 between the angular bend 32 and stop 34 is the interior section 26.
In one embodiment, one or more openings 54 have been placed within a medical bed frame at desired locations. The mounting plates 12 are then secured to the frame of the medical bed as earlier described, where the rear 18 of the mounting plate 12 is centrally positioned over the openings 54.
Any desired number of adapter buckles 14 may then be coupled to any desired number of mounting plates 12 on the medical bed frame. In some embodiments, an adapter buckle 14 will remain coupled to a mounting plate 12 during periods of nonuse. In this embodiment, a strap of a medical device will be looped through a pre-connected horizontal slot 46 of the adapter buckle 14 to enable adjustable tensioning of a patient restraint device.
In at least one alternative embodiment, the horizontal slot 46 of the adapter buckle 14 may be initially engaged to the strap of a patient restraint device, where the adapter buckle 14 may be coupled to the mounting plate 12 immediately prior to the adjustment of the tension to be placed onto the patient restraint device.
In one embodiment, the adapter buckle 14 may be coupled to the mounting plate 12 by the insertion of the stop 34 through the vertical slot 20, and the rotation of the head 28, arm 30, and stop 34 approximately 90°, where the angular bend 32 is used to position the head 28 upwardly proximate to the upper edge 36 and front 16 of the mounting plate 12. In this position, the exterior section 24 including the head 28 is exterior to the vertical slot 20. The interior section 26 including the stop 34 is interior to the vertical slot 20. The stop 34 is positioned proximate to the rear 18 and proximate to the vertical slot 20 within the opening 54.
The size dimensions selected for the stop 34 are required to be less than the height dimension selected for the vertical slot 20, in order for coupling of the adapter buckle 14 and mounting plate 12 to occur.
In one embodiment, the stop 34, prior to positioning through the vertical slot 20, may be turned 90° where the stop 34 is in a vertical orientation as opposed to a horizontal operational orientation which occurs following coupling. When the stop 34 is in the pre-coupled vertical orientation, one end 56 of the “T” may be inserted into the vertical slot 20. Depending on which end 56 of the stop 34 has been inserted into the vertical slot 20, the arm 30 may be lowered or raised until the arm 30 contacts either the upper or lower terminus of the vertical slot 20. The opposite end 56 of the stop 34 may then be either raised or lowered depending upon the location of the arm 30 relative to the vertical slot 20, so that the opposite end 56 of the “T” of the stop 34 is rotated inwardly through the vertical slot 20, positioning both ends 56 to the rear 18 of the mounting plate 12. In this position a portion of the arm 30 and both ends 56 of the stop 34 will be proximate to the rear 18 of the mounting plate 12 within the opening 54. Also a portion of the arm 30 and the head 28 will be proximate to the front 16 of the mounting plate 12. In this second pre-coupled position, the angular bend 32 will be facing to the either of the left or to the right as an individual faces the restraint assembly 10.
In the embodiment where the angular bend 32 is proximate to the left relative to the mounting plate 12, the head 28 may be rotated from a relative position of 270° (or facing horizontally to the left) upwardly 90°, to the final 0° or 360° position. In this coupled position the head 28 is positioned upwardly relative to the vertical slot 20 and is proximate to the upper edge 36 of the mounting plate 12. In this embodiment the stop 34 proximate to the rear 18 of the vertical slot 20 has been rotated to a substantially horizontal position where each of the ends 56 of the stop 34 extends normally and outwardly relative to the vertical slot 20. The extension of the ends 56 of the stop 34 outwardly relative to the vertical slot 20 prohibits the adapter buckle 14 from being pulled forwardly or outwardly away from the opening 54 and through the mounting plate 12. The ends 56 function as anchors or stops prohibiting the separation of the adapter buckle 14 from the mounting plate 12 following coupling.
In an alternative embodiment, where the angular bend 32 is positioned to the right relative to the mounting plate 12, the head 28 may be rotated from a relative position of 90° (or facing horizontally to the right) upwardly 90° to the left, to a final 0° or three 360° upward position. In this embodiment, the head 28 is disposed upwardly relative to the vertical slot 20 and is proximate to the upper edge 36 of the mounting plate 12. In this orientation, the stop 34 proximate to the rear 18 of the vertical slot 20 has been rotated to a substantially horizontal position where each of the ends 56 of the stop 34 extend normally and outwardly relative to the vertical slot 20. The extension of the ends 56 of the stop 34 outwardly relative to the vertical slot 20 prohibit the adapter buckle 14 from being pulled forwardly or outwardly away from the opening 54 and through the mounting plate 12. The ends 56 function as anchors or stops prohibiting the separation of the adapter buckle 14 from the mounting plate 12 following coupling.
In an at rest position the head 28 may be adjacent to the front 16 and upper edge 36, where the restraint assembly 10 is in a substantially flat position relative to a surface. In addition, in the at rest position, the interior section 26, including the arm 30 and the ends 56 of the stop 34 extend rearwardly relative to the vertical slot 20 and downwardly at an approximate angle of 145° downwardly from vertical within the opening 54. In order to initiate use of the restraint assembly 10, the head 28 is moved downwardly and outwardly relative to the front 16 of the mounting plate 12.
In an operational, tensioned position, the head 28 and horizontal slot 46 will be lowered to an angle of approximately 35° downwardly from a vertical position away from the mounting plate 12. In the operational position, the ends 56, stop 34 and interior section 26 of the adapter buckle 14 will be disposed in a substantially normal and horizontal position relative to the vertical mounting plate 12 within the opening 54. The head 28 and horizontal slot 46 will be positioned outwardly relative to the front 16 of the mounting plate 12, so long as a strap of a patient restraint device is engaged to the horizontal slot 46 of the head 28.
In at least one alternative embodiment, the mounting plate 12 may include a lock opening 22 disposed below the vertical slot 20 providing access to the rear 18 and into the opening 54. In this embodiment, the lock opening 22 is constructed and arranged to receive a lock assembly 40 having a lock cylinder 42 which in turn includes a keeper 44. The keeper 44 is disposed within the opening 54 below the stop 34 and ends 56.
In at least one embodiment, a doughnut shaped lock spacer 62 surrounds the lock cylinder 42 prior to insertion of the lock cylinder 42 into the lock opening 22. The lock spacer 62 may be formed of metal, plastic, or rubber materials at the discretion of an individual. The lock spacer 62 is preferably adjacent to and is in contact with the front 16 of the mounting plate 12. The lock spacer 62 may be used to assist in the positioning of the keeper 44 directly below the stop 34 and arm 30. The lock spacer 62 may also provide a moisture seal preventing the lock cylinder 42 from exposure to moisture, which over time may lead to rust and malfunction of the lock assembly 40.
The lock spacer 62 may include a rounded or angled face as positioned adjacent to a key opening to improve the aesthetic appearance of the lock assembly 40.
In one embodiment, the lock assembly 40 may include a positioning adjuster which may be attached to the lock cylinder 42 following the attachment of the lock spacer 62 adjacent to the key face. The positioning adjuster may then be tightened to secure the lock spacer 62 in a desired position between the lock face and the positioning adjuster immediately prior to the positioning of the lock cylinder 42 within the lock opening 22.
Following insertion of the lock cylinder 42 into the lock opening 22 an individual may use a lock retainer to interface with the lock cylinder 42 to the rear 18 in order to sandwich the mounting plate 12 between the lock spacer 62 and the lock retainer. The use of the lock spacer 62 on the front 16 and lock retainer on the rear 18 may facilitate the exact positioning of the lock cylinder 42 and keeper 44 relative to the stop 34.
The lock assembly 40 may be attached to the mounting plate 12 before or after the coupling of the adapter buckle 14 to the mounting plate 12.
