The present invention relates to an arm immobilization apparatus which is usable for various purposes and methods to wear the apparatus.
There are several designs currently available for apparatus used to immobilize an arm (typically referred to as slings). The designs range from those using a triangular bandage to those with an arm holder and a fastening strap(s). However, the current designs include flaws/limitations which have not been addressed despite an extended duration of availability in the market.
One of the issues for the current designs in the market relates to how the slings merely support the arm and does not adequately prevent movement of the arm. Essentially, the current designs in the market do not provide holistic immobilization pertaining to the injured arm.
Another issue for the current designs in the market relates to how extended use leads to significant discomfort at the neck and/or shoulder blades of the user because of the substantial loading the neck and/or shoulder blades undergoes when the arm is placed in the sling. This is because of strap design of the current designs in the market which apply substantial stresses to the neck and/or should blades during use. Furthermore, the straps used in the current designs in the market also require regular re-adjustment, re-attachment, re-strapping after extended usage. This constant need for adjustment and/or intervention is inconvenient and burdensome for the user.
Furthermore, in circumstances when the user has an arm which is completely/significantly dysfunctional, yet another issue for the current designs relates to difficulty of putting on a sling without assistance from a third party. This comprises an ability of the user to administer self-care in the absence of third parties.
Moreover, even though current designs provide support for the arm, they typically do not provide sufficient support for the shoulder and the elbow, and this inadequacy may lead to shoulder subluxation. In addition, thin straps used for current designs exert localized pressure and unfortunately cause discomfort to the user over an extended duration of time.
Finally, it should also be noted that current designs are typically constructed/fabricated in a manner which is not robust and prone to wear and tear leading to a short duration of use before replacement and/or adjustment becomes necessary.
Thus, it should be noted that the current designs have issues.
According to a 1st aspect of the invention, there is provided an arm immobilization apparatus comprising: a main body arranged to be of a substantially oblong shape; and a location strap having first and second ends, wherein the first end is arranged to be coupled to a long edge of the main body, and the second end is coupled to first and second short edges of the main body.

In order that the present invention may be fully understood and readily put into practical effect, there shall now be described by way of non-limitative example only preferred embodiments of the present invention, the description being with reference to the accompanying illustrative figures.
Reference is made to the Figures to describe preferred embodiments of the apparatus of the present invention.
There is provided an arm immobilization apparatus 20, according to a first embodiment. The apparatus 20 can be used for various purposes such as, for example, physical rehabilitation, disability therapy, medical treatment, sports, day-to-day regular activities, and so forth. The apparatus 20 is able to function as more than a typical arm sling, as will be evident in the subsequent paragraphs. The apparatus 20 comprises a main body 22 being of a substantially oblong shape. Specifically, the substantially oblong shape of the main body 22 provides a sleek streamlined design for the apparatus 20 and this can also minimize weight and amount of material being used. The main body 22 is fabricated from a hard-wearing, lightweight and flexible fabric. Suitable fabrics can be made from naturally occurring materials or synthetic materials demonstrating the aforementioned desired properties.
The apparatus 20 also includes a location strap 24 attached to the main body 22. The location strap 24 is used to mount the apparatus 20 at desired portion of a user's body and also to prevent the apparatus 20 from moving/sliding during use of the apparatus 20. This will be described in greater detail when describing the use of the apparatus 20. The location strap 24 as shown is attached to the main body 22 which causes difficulty in removing the location strap 24 from the main body 22. However, the location strap 24 can also be attached to the main body 22 in a manner which enables ease of removal in-situ such that the location strap 24 can be re-located to another position on the main body 22. For example, the location strap 24 is shown to be attached to a first long edge 21, but the location strap 24 can also be attached to a second long edge 23. This allows the apparatus 20 to be usable with both a left arm and a right arm of the user. Moreover, the location strap 24 can have a variable length to enable it to be customizable for needs of any user, because the location strap 24 can be either elastic (as shown) or adjustable length-wise.
In addition, the apparatus 20 can also include a compartment 26 for placement of the arm which is being immobilized. The compartment 26 can be a sleeve made using a stretchable fabric, the stretchable fabric being able to allow dissipation of heat from within the compartment 26. The compartment 26 is sized to accommodate the arm up to an elbow portion. The sleeve should not conform too tightly to the arm as this may cause discomfort to the user. It is advantageous for the sleeve to be made using the stretchable fabric as a portion of the arm may be encased within a cast, and the stretchable fabric allows the arm encased within the cast to be placed within the sleeve. Instead of the compartment 26, it may be possible to use at least two straps to secure the arm to the main body 22. The at least two straps can be attachable to the main body 22, or they can be standalone and used to secure the arm which is being immobilized to the main body 22.
In the apparatus 20, a first short edge 28 of the main body 22 is configured to be secured to a second short edge 30 of the main body 22. In the Figures, the first short edge 28 and the second short edge 30 are shown to have a pair of fastening mechanisms 32, 34 respectively such that the edges 28, 30 are able to be secured to one another at a back of the user. In this instance, even though two sets of fastening clips are used as the fastening mechanisms 32, 34, it can be possible for a single fastening clip to be used. In addition, while the edges 28, 30 are not shown to overlap in this instance, if other forms of fastening mechanisms are used, then it can be possible for the edges 28, 30 to overlap. When the edges 28, 30 overlap, there is no necessity for straps 36.
Furthermore, the apparatus 20 can also include at least one device such as, for example, at least one sensor, a transmitter and so forth. The devices can be configured to perform at least one task such as, for example, detection, recordal, analysis, transmission of the user's condition and/or state of activity.
Referring to
It should be appreciated that the apparatus 20 also provides support for the elbow and shoulder of the user 18. Referring to
Furthermore, the apparatus 20 can also be used in the recovery of, for example, brachial plexus injury, post-obstetric delivery injuries to newborns, flail arm, hemiplegia, spinal cord injuries from C4 and below, mono-neutritis injuries, and so forth. Moreover, the apparatus 20 can be deployed quickly in emergency situations (in both military and civilian scenarios) involving either single or multiple casualties. In addition, the apparatus 20 can be used as an aid to facilitate an independent active lifestyle, whereby the users are able to rely on their free arm to carry out the activities and tasks which they desire, without obstruction by and without causing further injury to their immobilized arm. It should also be noted that the apparatus 20 enables prolonged use with minimal discomfort to the user.
In general, on a holistic level, the apparatus 20 beneficially promote and allow body balance during when users are engaging in physical activities, since it is to be pointed out that conventionally, users with flail arms often lose holistic balance during performance of physical activities.
Finally, the overall posture of the user also improves when using the apparatus 20 as the securing of the apparatus 20 causes an upper portion of the user's torso to be pulled backwards which ensures that the user's back is straightened. This effect on the overall posture alleviates pressure in the user's back and shoulders, thereby minimizing discomfort for the user and enabling prolonged use of the apparatus 20.
Referring to
Based on the preceding paragraphs, it is noted that the apparatus 20 provides significant improvements compared to known devices, some of which have already been in use for long durations of time without undergoing any enhancements. Given the minimization of discomfort for users of the apparatus 20, it should be appreciated that the apparatus 20 is not a temporary/transient medical device if the user has an arm which is completely/significantly dysfunctional. The apparatus 20 can be a long term aid to enable an active, healthy and independent lifestyle for the user.
The remaining configurations will be described hereinafter. For the sake of brevity, description of like elements, functionalities and operations that are common between the different configurations are not repeated; reference will instead be made to similar parts of the relevant configuration(s).
A second embodiment is depicted in
Moreover, it is to be appreciated that the “O” ring 810 is arranged on the apparatus 800 such that when the apparatus 800 is worn by a user, the “O” ring 810 is positioned at a substantially central portion on the back of the user to enable a more ergonomic and comfortable fit. Also in this embodiment, a distance between the first and second short edges 808a, 808b of the main body 802 is not adjustable (i.e. cannot be shorten/lengthen), unlike in the first embodiment. Nonetheless, it will be understood that the first short edge 808a of the main body 802 is coupled to the second short edge 808b of the main body 802. It is to be highlighted that the arrangement of using the “O” ring 810 provides a certain degree of movement to the location strap 804 (via being slidably movable around on at least a portion of the “O” ring 810), and so when the apparatus 800 is worn by a user, flexibility in terms of enabling the apparatus 800 to provide an improved and more comfortable fit to the said user is granted by the movable location strap 804. It is also to be appreciated that a comfort padding 812 (or the like) of a suitable size and shape may be used to provide a support backing for the portion of the apparatus 800, at where the coupling intersection point formed by the “O” ring 810 is located. Further, the comfort padding 812 may collectively hide the “O” ring 810, the second end 806 of the location strap 804, and the first and second short edges 808a, 808b of the main body 802, so that the back of the apparatus 800 appears visually tidy.
In addition, the main body 802 of the apparatus 800 comprises first and second portions 814a, 814b, in which at least the first portion 814a is adjustably coupled to the second portion 814b to enable an overall length of the main body 802 to be configurable. In
With reference to
A third embodiment is depicted in
It is to be appreciated that both the apparatuses 800, 1100 of
Whilst there have been described in the foregoing description preferred embodiments of the present invention, it will be understood by those skilled in the technology concerned that many variations or modifications in details of design or construction may be made without departing from the present invention. For example, in the second embodiment, the second end 806b of the location strap 804 need not be movably coupled to the first and second short edges 808a, 808b of the main body 802—instead, the second end 806b of the location strap 804 can be fixedly attached to both the first and second short edges 808a, 808b of the main body 802 for a simpler arrangement. Hence, the “O” ring 810 (or other equivalent implements) is not required under such a variation.
In addition, for certain variant embodiments, the location strap 804 need not be adjustably coupled to the long edge of the main body 802—instead, the first end 806a of the location strap 804 is simply fixed to the long edge of the main body, and hence there is then no need for the quick release device 807. Further alternatively, the first end 806a of the location strap 804 may configured to be dynamically mountable to different desired multiple positions along the long edge of the main body 802, which beneficially provides a better comfortable fit of the location strap 804 to different users' bodies, according to their respective body sizes. Hence, different mounting points (not shown) are provided and spaced along the long edge of the main body 802 to enable the said variant feature described in the preceding sentence. Separately, the fastening device 816 may also be arranged to permit a greater range of adjustment in order that an immobilized arm may rest at an angled position which is between about 60° to 90° position relative to (the vertical axis of) the body of an associated user.
It is to be pointed out that broadly, a method of wearing the apparatuses 800, 1100 of
