Predictive double-release alarm belt

Abstract

Systems and methods for monitoring the location of a patient using a double-release alarm belt. The belt may include a plurality of straps configured to be releasably attached to one another and an alarm system that is triggered when at least one of the straps is disengaged from the other strap or straps. One strap may be disengaged from another strap by pulling the first strap in a first direction and another strap may be disengaged from the yet another strap by pulling in a second direction. By requiring multiple straps to be released from one another, the amount of time it takes to remove the belt can be increased, which provides medical personnel additional time to reach a patient.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates, in general, to the field of fall prevention devices. More particularly, the present invention relates to a device that allows medical personnel to monitor the location of various patients. Specifically, a preferred embodiment of the present invention relates to a belt that can be secured about a device on which a patient sits or lays that alerts medical personnel when the belt is removed or partially removed.

2. Discussion of the Related Art

Falls and fall-related injuries pose significant health issues, especially for elderly individuals, To address these health issues, various fall-prevention equipment is commonly used in hospitals, assist care facilities, nursing homes, senior citizen facilities, and any other locations to protect patients and residents. For instance, various sensors, alarms, and other devices are used to monitor the location and movement of individuals. By way of example, many pieces of furniture, including chairs, beds, wheelchairs, toilets, and the like, feature sensors that alert medical personnel when an individual exits these pieces of furniture. In the event an individual stands up, the sensor can trip an alarm that alerts medical personnel. Once the alarm is sounded, appropriate attention can be given to the individual who may not be steady on his or her feet.

One such type of fall-prevention equipment relates to belts that are wrapped around a patient who is sitting in a chair or lying in a bed. In the event the individual wishes to get up from the chair or bed, he or she must disengage the belt. Once the fastener of the belt is disengaged, an alarm is sounded to alert the medical staff.

While these fall-prevention belts are helpful, further improvements are desired. For instance, current fall-prevention belts resemble traditional belts, which can be disengaged quickly and easily by simply separating the first end and the second end at a single release point. Once the first end and the second end are disengaged about the single release point such that the belt is completely separated, an alarm is sounded. As a result, once the alarm is sounded, the patient is able to immediately stand up and move around, as desired. This means that the medical personnel must act immediately, and even then, the patient may have stood up, moved, or fallen down.

Additionally, traditional fall-prevention belts are expensive, requiring them to be reused. In many settings, such as household settings, this is not an issue. However, in hospital settings, sterility concerns require extensive cleaning before a fall-prevention belt is ready to be reused. This also adds to the cost of using and maintaining fall prevention belts.

What is needed, therefore, is a fall-prevention alarm belt that addresses at least the issues outlined above. More specifically, an alarm belt that provides medical personnel with additional time to reach the patient before the patient is able to stand up is needed. Similarly, an alarm belt that requires additional time for a patient to disengage is further needed. Further, what is needed is an affordable, disposable fall-prevention belt that can be installed to a chair, a bed, or another piece of furniture on which a patient is sitting or lying.

SUMMARY AND OBJECTS OF THE INVENTION

By way of summary, the present invention is directed to a double-release alarm belt that is used with a device that holds or supports a patient. A primary object of the invention is to provide an apparatus that allows medical personnel to monitor the location of the patient relative to the device. Another object of the invention is to provide an apparatus that is affordable and disposable for industries where sterility concerns are prevalent.

In accordance with a first aspect of the invention, these objects are achieved by providing an apparatus having at least three straps, a cord configured to detect movement of at least one of the straps, and an alarm system connected to the cord. The at least three straps may be releasably secured to one another around the device and the patient. For instance, the at least three straps may include a first elongated strap, a second elongated strap releasably attached to the first elongated strap, a third elongated strap, and a fourth elongated strap releasably attached to the third elongated strap.

The at least three straps may be disengaged from the device and the patient by moving a first strap in a first direction and then moving a second strap in a second direction. Once the first strap is moved in the first direction, the cord may provide a transmission to the alarm system that results in the sounding of the alarm system. For instance, the third elongated strap may be disengaged from the fourth elongated strap by pulling the third elongated strap in the first direction. Once this occurs, the alarm system may be triggered. Thereafter, the first elongated strap may be disengaged from the second elongated strap by pulling the second elongated strap in the second direction opposite the first direction.

The apparatus may also include first, second, third, and fourth fasteners. For instance, the first fastener may be located on an upper side of the first elongated strap. The second fastener may be located on an underside of the second elongated strap, such that the second fastener is configured to releasably fasten to the first fastener. Additionally, the third fastener may be located on an underside of the third elongated strap. Finally, the fourth fastener may be located on an upper side of the fourth elongated strap, such that the first fastener is configured to releasably fasten to the third fastener. Also, a bond between the third fastener and the fourth fastener may be weaker than a bond between the first fastener and the second fastener.

Further still, the apparatus may include first and second handles. The first handle may be mounted to an upper side of the third elongated strap. This allows the third elongated strap to be disengaged from the fourth elongated strap by pulling on the first handle. The second handle may be mounted to an upper side of the second elongated strap to allow the second elongated strap to be disengaged from the first elongated strap.

In accordance with another aspect of the invention, these objects are achieved by providing an apparatus comprising an inventive double-release alarm belt with a first elongated strap, a second elongated strap, a shortened strap, a cord, and an alarm system. The first elongated strap, the second elongated strap, the shortened strap, and the cord can be disposable, or they can be reusable.

The first elongated strap may have a first end, a second end, a midportion located between the first and the second end, an upper side, and an underside. The first elongated strap may also have a hook mechanism that is attached to the first end of the first elongated strap. The hook mechanism may be used to engage a second end of the second elongated strap. More specifically, the hook mechanism may comprise a first ring and a second ring where the second end of the second elongated strap is threaded through the first ring and the second ring. Additionally, the first elongated strap may have a first fastener extending along the underside of the second end of the first elongated strap.

The shortened strap may also have a first end, a second end, an upper side, and an underside. The shortened strap may be attached to the midportion of the first elongated strap about the first end of the shortened strap. Additionally, a second fastener may extend along the upper side of the shortened strap from the first end of the shortened strap to the second end of the shortened strap.

Similarly, the second elongated strap may have a first end, a second end, an intermediate portion located between the first end and the second end, an upper side, and an underside. A third fastener may extend along the underside of the first end of the second elongated strap and a fourth fastener may extend along the upper side of the intermediate portion.

The first fastener may he releasably engaged by the fourth fastener, and the second fastener may he releasably engaged by the third fastener. More specifically, the first fastener may be releasably held together with the fourth fastener by a first bond and the second fastener may he releasably held together with the second fastener by a second bond. The first bond may be weaker than the second bond. This allows the bond between the first fastener and the fourth fastener to be easily broken. It is more difficult to break the bond between the second fastener and the third fastener. In this way, a patient can easily break the first bond, but it will be more difficult to break the second bond. Also, the first fastener is disengaged from the fourth fastener using a first force and the second fastener is disengaged from the fourth fastener using a second force. The first force is less than the second force. Each of the fasteners may be selected from one of a hook fastener and a loop fastener.

The cord is associated with the first elongated strap, the second elongated strap, and the shortened strap and is in communication with an alarm system. If the first fastener is disengaged from the fourth fastener as monitored by the cord, the alarm system will generate an audible sound. This will notify medical personnel that there is risk that the patient is preparing to leave the device before the patient is actually able to leave the device. To disengage the various fasteners, the first fastener is disengaged from the fourth fastener when the first fastener is pulled in a first direction. Next, the second fastener may be disengaged from the third fastener by pulling in a second direction, which is opposite to the first direction. By requiring the patient to pull in the first direction and then the second direction, it takes additional time to disengage the double-release alarm belt in comparison to previous belts.

The inventive double-release belt may also include a first handle that is mounted to the upper side of the second end of the first elongated strap. Thus, the first handle is used to disengage the first fastener from the fourth fastener. The double-release belt also may include a second handle mounted to the upper side of the first end of the second elongated strip. Therefore, the second handle is used to disengage the first fastener from the fourth fastener.

The double-release belt preferably may also include a fifth fastener. The fifth fastener may be associated with the second end of the second elongated strap. The fifth fastener may be used to secure the first elongated strap, the second elongated strap, and the shortened strap in a wrapped position. Additionally, the fifth fastener may be used to secure the second end of the second elongated strap to the double-release belt once installed.

In accordance with another aspect of the invention, these objects are achieved by providing a method of using the double-release alarm belt with a device holding a patient. The first step of the method is wrapping the double-release arm belt around the patient. Next, the double-release alarm belt is wrapped around the device. A first end of the double-release alarm belt is then engaged with a second end of the double-release alarm belt to secure the first and second ends to one another. Next, an alarm system is connected to the double-release alarm belt by a cord.

The method may include additional steps. The first elongated strap may be disengaged from the second elongated strap about a first portion. For instance, a first handle can be pulled to disengage the first elongated strap from the second elongated strap about a first portion. When this occurs, an audible alarm can be created by the alarm system. Additionally, the first elongated strap may be disengaged from the second elongated strap about a second portion. For instance, a second handle can be pulled to disengage the first elongated strap from the second elongated strap about a second portion. When this occurs, the patient is released so that he or she can move away from the device. Also, the first end of the double-release alarm belt may be threaded through a first ring and a second ring associated with the second end of the double-release belt. When this occurs, the belt is snug about the patient. Additionally, the first end of the double-release alarm belt can be secured in place using a hook and loop fastener.

In accordance with another aspect of the invention, a double-release alarm belt for use with a device holding a patient may include a first elongated strap, a shortened strap, a second elongated strap, and an alarm system. The shortened strap may extend from the first elongated strap. The second elongated strap may be configured to be releasably attached to the first elongated strap and to be releasably attached to the shortened strap. The alarm system is triggered when the second elongated strap is disengaged from the first elongated strap. The second elongated strap may be disengaged from the first elongated strap by pulling the first elongated strap in a first direction. The second elongated strap may also be disengaged from the shortened strap by pulling the second elongated strap in a second direction opposite the first direction.

These, and other aspects and objects of the present invention will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following description, while indicating preferred embodiments of the present invention, is given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the present invention without departing from the spirit thereof, and the invention includes all such modifications.

DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments described in detail in the following description.

1. System Overview

The current invention relates to a belt with two releasable straps portions which is connected to an alarm that can he secured around an occupant of a chair, bed, or other supporting device to monitor patient movement non-invasively. When a first releasable strap portion is disengaged by pulling in a first direction, an alarm will sound. The second releasable strap portion can then be disengaged by pulling in a second direction, which is opposite to the first direction. This gives an early warning to the medical personnel before the occupant attempts to exit the chair or bed. As a result, the necessary staff has time to intervene to assist the occupant who may be a fall risk. The belt could either be disposable or reusable based on the materials used. By offering both disposable and reusable belts, cost efficiency can be optimized depending on the specific context in which the belt is used. This invention is superior to previous sensor pads or alarms that typically only sound once the occupant has already exited the chair, bed, or other supporting device.

2. Detailed Description of Preferred Embodiments

The inventive double-release alarm belt 30 is generally shown in the figures. The double-release alarm belt 30 is used to monitor the position of a patient 34 or other individual who is resting on a support device 32, for instance, a chair, a bed, a wheel chair, a cardiac chair, a recliner, or other furniture. The double-release alarm belt 30 has a first elongated strap 36, a second elongated strap 64, and an alarm system 80. The double-release alarm belt 30 may also include a shortened strap 52. The first elongated strap 36, the second elongated strap 64, and the shortened strap 52 may be releasably affixed to one another about a first portion 112 and a second portion 114, as will be further described below. When the first elongated strap 36 and the second elongated strap 64 are disengaged about the first portion 112, the alarm system 80 may create an audible alarm. In this way, the double-release alarm belt 30 provides medical personnel with an advanced warning before the patient 34 is able to disengage the second elongated strap 64 from the shortened strap 52 about the second portion 114 to get up from the device 32.

Initially, the first elongated strap 36 will be described. The first elongated strap 36 can be seen, for instance, in FIGS. 2 and 4. The first elongated strap 36 has a first end 38, a second end 40 opposite the first end 38, and a midportion 42 located between the first end 38 and the second end 40. Additionally, the first elongated strap 36 may have an upper side 44 and an underside 46. A hook mechanism 48 may be attached to the first end 38 of the first elongated strap 36. The hook mechanism 48 may include a first ring 94 and a second ring 96. Additionally, a first fastener 50 may be associated with the first elongated strap 36. As shown, the first fastener 50 extends along the underside of the first end 38 of the first elongated strap 36. Additionally, the first elongated strap 36 may have a first handle 86 that is mounted to the upper side 44 of the first elongated strap 36 along the second end 40. The length of the first handle 86 may be substantially the same length of the first fastener 50.

Moving on, the shortened strap 52 also has a first end 54 and a second end 56 opposite the first end 54, as well as an upper side 58 and an underside 60. The shortened strap 52 is best seen in FIG. 20. As shown, the first end 54 may be attached to the midportion 42 of the first elongated strap 36. Additionally, a second fastener 62 extends along the upper side 58 of the shortened strap 52 from the first end 54 of the shortened strap 52 to the second end 56 of the shortened strap 52.

Next, the second elongated strap 64 will be described, which again is best seen in FIGS. 2 and 4. Somewhat similar to the first elongated strap 36, the second elongated strap 64 has a first end 66, a second end 68, and an intermediate portion 70 located between the first end 66 and the second end 68. The second elongated strap 64 may also have an upper side 72 and an underside 74. Additionally, a third fastener 76 and a fourth fastener 78 may be associated with the second elongated strap 64. More specifically, the third fastener 76 may be mounted along the underside 74 of the first end 66 of the second elongated strap 64. The fourth fastener 78 may be mounted along the upper side 72 of the intermediate portion 70. Also, the second elongated strap 64 may have a handle 88 that is mounted to the upper side 72 of the second elongated strap 64 along the first end 66. Further still, the second elongated strap 64 may have a fifth fastener 90 located about the second end 68. The fifth fastener 90 can hold the double-release alarm belt 30 in a wrapped position 92, as shown in FIG. 5. FIGS. 6-11 show the double-release alarm belt 30 as it is unwrapped. Additionally, the fifth fastener 90 can be used to secure the second end to the double-release alarm belt 30 once installed about the patient 34 and the device 32.

As shown in FIGS. 6, 15, 16, 17, 19, and 20, each of the fasteners 50, 62, 76, 78 may be selected from one of a hook fastener 106 and a loop fastener 108. Other types of fasteners could similarly be used, such as snaps, adhesive, ties, and the like. Additionally, as shown, the compatible fasteners can be color-coded to simplify the assembly or re-assembly process. For instance, the first fastener 50 and the fourth fastener 78 are made of white hook and loop fasteners. Similarly, the second fastener 62 and the third fastener 76 are made of blue hook and loop fasteners. In this way, medical personnel can easily re-assemble the double-release alarm belt 30 without risk of engaging the wrong fasteners with one another. This is especially helpful where the double-release alarm belt 30 is reusable. Also, the handles 86, 88 can be a different color from the rest of the double-release alarm belt 30, so that they can more easily be seen and distinguished from the other parts of the belt 30. For instance, the handles 86, 88 may be a fluorescent yellow.

Each of the first elongated strap 36, the shortened strap 52, and the second elongated strap 64 may be disposable. Additionally, the cord 110, which can be disengaged from the alarm system 80, can also be disposable. For instance, the disposable version of the belt 30 could be made of a silver conductive fabric, as well as a nylon or foam laminate. These materials are typically less expensive in comparison to the materials needed to manufacture previous reusable belts. Additionally, the disposable version could have hook and loop fasteners as opposed to buckles, which can be expensive. For instance, the disposable materials may be 25-75% less expensive than those associate with traditional belts, and more preferably 40-50% less expensive than traditional belts. Such a configuration would be especially appealing in situations where the double-release alarm belt 30 is used in hospital settings or other environments where sterility must be maintained. By having an affordable disposable alarm belt 30, the belt 30 can simply be thrown away after use without the need to sterilize a previously-used belt, which can be time-consuming and costly. Alternatively, in situations where sterility is not a concern, the double-release alarm belt 30 could be reusable. For instance, such a configuration could include materials, such as nylon webbing, seat belt buckles, biothan webbing, and silver conductive fabric. Alternatively, any aspect of the belt 30 could be made of any other number of materials, including non-woven materials, such as plastic or paper. Regardless of the material, the belt 30 is preferably configured to be able to withhold forces of over 100 pounds before failure.

Possible dimensions of the first elongated strap 36, the shortened strap 52, and the second elongated strap 64 will now be described. However, it should be noted that straps of various dimensions may be used to accommodate different uses. Additionally, it should be noted that larger straps could be used for patients with larger waist sizes or for use with larger chairs, beds, cardiac chairs, recliners, and the like.

For instance, the length of the double-release alarm belt 30 could be approximately 60-100 inches in length and, more preferably, approximately 78 inches, as shown in FIGS. 1 and 2. Additionally, typical belts 30 will be approximately 2 inches in height, although again, different dimensioned belts could be used as required by the specific use. In such an embodiment, the first elongated strap 36 could be 20-40 inches, and more preferably 27.5 inches. Additionally, in this embodiment the second elongated strap 64 could be between 75-105 inches, and more preferably 90 inches.

An alternative double-release alarm belt 30 could be much longer, for instance, the length of the double-release alarm belt could be approximately 70-110 inches in length and, more preferably, approximately 92 inches as shown in FIGS. 3 and 4. Additionally, typical belts 30 will be approximately 2 inches in height, although again, different dimensioned belts could be used as required by the specific use. In this embodiment, the first elongated strap 36 could be 25-55 inches, and more preferably 40 inches. Additionally, in this embodiment the second elongated strap 64 could be between 75-105 inches, and more preferably 90 inches. As such, the same second elongated strap 64 could be used with either embodiment, with different first elongated straps 36 being used, depending on how the belt 30 will be used.

Functionality of the cord 110 and alarm system 80 will now be described. The cord 110 is embedded within the second elongated strap 64 and monitors the locations of the first fastener 50 and fourth fastener 78. More specifically, when the fourth fastener 78 is pulled away from the first fastener 50, the cord 110 transmits this information to the alarm system 80, and the alarm system 80 generates an audible alarm. For instance, an electrical circuit can be completed where the first and fourth fasteners 50, 78 are connected to one another. When these fasteners 50, 78 are pulled apart from one another, the electrical circuit can be interrupted. Once the circuit is interrupted, the alarm can be triggered. Alternatively, a cord need not be included with the system, but instead, a wireless or Bluetooth system could be used to wirelessly trigger the alarm system 80 to generate the audible alarm when the first fastener 50 and the fourth fastener 78 are separated. The double-release alarm belt 30 can be used with any number of various fall-prevention alarm systems, as known to those of skill in the art. For instance, the belt 30 can be used with various POSEY fail alarms, including POSEY KEEPSAFE, POSEY KEEPSAFE DELUXE, POSEY KEEPSAFE SCOUT, and POSEY SITTER ELITE fall alarms.

To assemble the double-release alarm belt 30, the first fastener 50 is releasably engaged with the fourth fastener 78 and the second fastener 62 is releasably engaged with the third fastener 76. Once the double-release alarm belt 30 has been assembled, it can be installed about the patient 34. Initially the patient 34 is seated or laid onto a piece supporting equipment device 32, for instance, chairs, beds, recliners, and the like, as shown in FIG. 21. The belt 30 is wrapped around the patient's waist with the hook mechanism 48 located behind the patient 34. See FIGS. 21 and 22. Preferably, the belt 30 is located at approximately a 45. degree angle relative to the ground, although the specific angle could vary depending on the comfort of the patient 34, as shown in FIG. 22. The position of the first end 38 of the first elongated strap 36 and the second end 68 of the second elongated strap 64 should be positioned behind the device 32, as shown a chair back, as low as possible so that the belt 30 cannot slide up off the chair. Next, the second end 68 of the second elongated strap 64 is threaded through the hook mechanism 48, as shown in FIG. 23. More specifically, the second end 68 of the second elongated strap 64 is first threaded through the first ring 94 and the second ring 96, then back over one ring and through the other, as known to one of ordinary skill in the art. The second end 68 is then tightened so that it is securely held within the hook mechanism 48 so that the belt 30 is snug about the patient 34 and the supporting device 32. The medical personnel can verify that the belt 30 is not overly constricting by sliding an open hand between the belt 30 and the patient 34. Finally, a fifth fastener 90 located on the second end 68 of the second elongated strap 64 is engaged with a side of the double belt 30 as shown in FIG. 23. In this way, the loose second end 68 does not hang down on to the floor. Finally, the alarm cord 110 is connected to the alarm system 80 by inserting a jack 116 into a port 118 of the alarm system. Thereafter, the alarm system 80 is turned on.

Once the belt 30 has been installed, the position of the patient 34 about the device 32 can be monitored. In the event that the patient 34 begins to disengage the double-release alarm belt 30, the medical personnel will be notified. This first occurs when the first fastener 50 and fourth fastener 78 are pulled apart with a first force 102, such that the bond 98 between these fasteners 50, 78 is interrupted, as seen in FIGS. 15, 16, and 25. Preferably, due to the locations of the fasteners 50, 78 relative to the first elongated strap 36 and the second elongated strap 64, the separation of the first fastener 50 and the fourth fastener 78 occurs by pulling the second end 56 of the first elongated strap 36 in a first direction 82. See FIG. 25. As described above, once the first fastener 50 and the fourth fastener 78 are pulled apart, the alarm will sound to notify medical personnel that the patient 34 is trying to get out of the device 32. Next, the second fastener 62 and the third fastener 76 are pulled apart with a second force 104, such that the bond 100 between these fasteners 62, 76 is interrupted as seen in FIGS. 19, 20, and 26. The first force 102 required to disengage the first fastener 50 and the fourth fasteners 78 is less than the second force 104 required to disengage the second fastener 62 and the third fastener 76. Due to the locations of the fasteners 62, 76 relative to the first elongated strap 36 and the second elongated strap 64, the separation of the second fastener 62 and the third fastener 76 occurs by pulling the first end 66 of the second elongated strap 64 in a second direction 84. See FIG. 26. Preferably, the first direction 82 is in the opposite direction as the second direction 84. This results in increased time and difficulty for the patient 34 to remove the double-release alarm belt 30 than if the patient 34 simply had to repeatedly pull two separate belts in the same direction.

Furthermore, the bond 98 between the first fastener 50 and the fourth fastener 78 can be weaker than the bond 100 between the second fastener 62 and the third fastener 76. In this way, the patient 34 can more easily disengage the first fastener 50 from the fourth fastener 78, at which time the alarm will be sounded. Thereafter, due to the stronger bond 100 between the second fastener 62 and the third fastener 76, it will be more difficult for the patient 34 to disengage these fasteners 62, 76. This makes it more difficult for the second bond 100 to be broken, which increases the amount of time that medical staff has to approach the patient 34 after the initial alarm has been sounded. In this way, potential falls of the patient can be minimized.

A method of using the double-release alarm belt 30 will now be described. Initially, the double-release alarm belt 30 is wrapped around the patient 34 as well as the device 32. Next, the first end 38 is engaged with the second end 68 to secure the ends 38, 68 to one another. Additionally, an alarm system 80 is connected to the double-release alarm belt 30, for instance, by a cord 110. Next, the first elongated strap 36 can be disengaged from the second elongated strap 64 about a first portion 112. This can occur When the first handle 86 is pulled to disengage the first elongated strap 36 from the second elongated strap 64 about the first portion 112. Once the straps 36, 64 are disengaged about the first portion 112, the alarm system 80 creates an audible alarm. For instance, this may occur where an electrical circuit is interrupted. Alternatively, various sensors can be used to detect when the straps 36, 64 are disengaged about the first portion 112, Of course, the alarm may be sounded using any other ways known to those of ordinary skill in the art to detect when the two straps 36, 64 are disengaged from one another. Thereafter, the first elongated strap 36 can be disengaged from the second elongated strap 64 about a second portion 114. This can occur when the second handle 88 is pulled to disengage the first elongated strap 36 from the second elongated strap 64 about the second portion 114. Thereafter, the patient 34 is released such that he or she can move away from the device 32. Additional steps may include threading the second end 68 of the double-release alarm belt 30 through the first ring 94 and the second ring 96 associated with the first end 38 of the belt 30 until the double-release alarm belt 30 is snug about the patient 34. Also, the second end 68 of the double,-release alarm belt 30 may be held in place using a hook and loop fastener 90.

Another embodiment of the double-release alarm belt 230 is shown in FIGS. 27-34. The components found in FIGS. 27-34 that have been previously described will he designated by the same reference numbers as those provided above incremented by 200.

Additionally, the fourth elongated strap 322 may have an upper side 342 and an underside 344. Also, a fourth fastener 346 may be associated with the fourth elongated strap 322. As shown, the fourth fastener 346 extends along the upper side 342 of the fourth elongated strap 322.

Installation of the belt will now be described. First, the first and second ends of the base are secured to the device 232,110 as shown in FIG. 28. Next, the patient 234 is rested on the middle portion 352. Thereafter, the elongated straps are installed. initially, the first elongated strap 236 is placed directly onto the patient 234. Thereafter, the second elongated strap 264 is placed on top of the first elongated strap 236. When this occurs, the first fastener 250 and the second fastener 262 make contact with one another and are fastened to one another. Next, the fourth elongated strap 322 is placed on top of the second elongated strap 264. Finally, the third elongated strap 320 is placed on top of the fourth elongated strap 322 such that the third fastener 334 and the fourth fastener 346 contact one another and are fastened together. Once this is complete, the double-release alarm belt 230 is secured in place as seen in FIG. 30.

As described above, once the third fastener 334 and the fourth fastener 346 are pulled apart by a first force 302, the alarm will sound to notify medical personnel that the patient 234 is trying to get out of the device 232 as described above. Next, the first fastener 250 and the second fastener 262 are pulled apart with a second force 304, such that the bond 300 between these fasteners 250, 262 is interrupted. The first force 302 required to disengage the third fastener 334 and the fourth fastener 346 is less than the second force 304 required to disengage the first fastener 250 and the second fastener 262. Preferably, the separation of the third and fourth fasteners 334, 346 occurs by pulling the second handle 288 in a first direction 282 and the separation of the first and second fasteners 250, 256 occurs by pulling the first handle 286 in a second direction 284 opposite the first direction 282. This results in increased time and difficulty for the patient 234 to remove the double-release alarm belt 30 than if the patient 34 simply had to repeatedly pull two separate belts in the same direction.

Furthermore, the bond (not shown) between the third fastener 334 and the fourth fastener 346 can be weaker than. the bond (not shown) between the first fastener 250 and the second fastener 262. In this way, the patient 34 can more easily disengage the third fastener 334 and the fourth fastener 346, at which time the alarm will be sounded. Thereafter, due to the stronger bond between the first fastener 250 and the second fastener 262, it will be more difficult for the patient 234 to disengage these fasteners 250, 262. This makes it more difficult for the second bond to be broken, which increases the amount of time that medical staff has to approach the patient 234 after the initial alarm has been sounded. In this way, potential falls of the patient can be minimized.
