- the patient Because the fluid from the IV bag is administered over a long period of time, the patient must be in vicinity of the IV bag, at least limited by the practical length of a tube that connects the IV bag to the needle that is inserted in the patient's vein. Being such, the patient is virtually tethered to the IV bag.
- the IV bag is supported by a portable IV holder, often having wheels.
- the patient is relatively free to move about to exercise, use the bathroom, etc.
- the patient pushes/pulls the IV holder, and hence the IV bag, along with them as they make their way to their desired destination.
- Such is often witnessed in many hospitals.
- the typical prior IV holder consisted of a substantially linear shaft with a base and wheels at one end and an arm extending from a distal end to which the IV bag is attached.
- the IV bag is typically supported anywhere from six to eight feet off of the floor.
- a full IV bag typically contains a pint of fluid and the fluid has a specific gravity similar to that of water
- a full IV bag typically weights around one pound.
- the weight of the IV bag and the distance from the substantially linear shaft creates an imbalance to the prior IV holder, the longer the arm and the heavier the IV bag, the greater the imbalance.
- any obstruction such as a change in floor surfaces, minor bumps, etc., will perturb the prior IV holder, possibly leading to the IV holder, and hence, the IV bag falling, which possibly leads to bursting of the IV bag, damaging furniture or equipment from the IV holder hitting such, bodily injury, etc.

Abstract
An IV holder includes a base for supporting the IV holder on a floor. A first end of a post extends from the base and a distal second end area of the post has an IV bag hook. The IV bag hook is positioned substantially over a center of gravity of the IV holder when the base is positioned on the floor. The post has an offset area so that the post doesn't interfere with an IV bag suspended from the IV bag hook.
Description
- This invention relates to the field of holders or stands and more particularly to a holder/stand for supporting an bag holding fluids such as an Intravenous (IV) bag.
- An intravenous bag or IV bag typically supplies fluid to a patient in a slow, controlled administration through a needle injected into the patient's vein, typically a vein in the patient's wrist, arm, or leg. There are many types of fluids that are delivered from an IV bag, through a needle and directly into a patient's vein including saline solution, blood products, medication, etc. The fluid is typically not under any external pressure and feeds through the needle by force of gravity, hence the IV bag needs to be positioned at a location above the patient to provide flow of the fluid from the IV bag into the patient's vein.
- Because the fluid from the IV bag is administered over a long period of time, the patient must be in vicinity of the IV bag, at least limited by the practical length of a tube that connects the IV bag to the needle that is inserted in the patient's vein. Being such, the patient is virtually tethered to the IV bag.
- To provide the patient with some degree of mobility, often the IV bag is supported by a portable IV holder, often having wheels. In such, the patient is relatively free to move about to exercise, use the bathroom, etc. The patient pushes/pulls the IV holder, and hence the IV bag, along with them as they make their way to their desired destination. Such is often witnessed in many hospitals.
- As will be shown, the typical prior IV holder consisted of a substantially linear shaft with a base and wheels at one end and an arm extending from a distal end to which the IV bag is attached. Although often adjustable in height, the IV bag is typically supported anywhere from six to eight feet off of the floor. Being that a full IV bag typically contains a pint of fluid and the fluid has a specific gravity similar to that of water, a full IV bag typically weights around one pound. Being that the IV bag is positioned on an arm, the weight of the IV bag and the distance from the substantially linear shaft creates an imbalance to the prior IV holder, the longer the arm and the heavier the IV bag, the greater the imbalance. As the patient walks to their destination, any obstruction such as a change in floor surfaces, minor bumps, etc., will perturb the prior IV holder, possibly leading to the IV holder, and hence, the IV bag falling, which possibly leads to bursting of the IV bag, damaging furniture or equipment from the IV holder hitting such, bodily injury, etc.
- What is needed is an IV holder that will reduce imbalances and, therefore, reduce the potential of tipping.
- In one embodiment, an IV holder is disclosed including a base for supporting the IV holder on a floor. A first end of a post extends from the base and a distal second end area of the post has an IV bag hook. The IV bag hook is positioned substantially over a center of gravity of the IV holder when the base is positioned on the floor. The post has an offset area so that the post doesn't interfere with an IV bag suspended from the IV bag hook.
- In another embodiment, an IV holder is disclosed including a base that has a plurality of wheels interfaced to a first side; the wheels for supporting the IV holder on a floor. The IV holder also includes a post (generally horizontal when the base is positioned on the floor). A first end of the post extends from the second side of the base (opposite from the first side of the base), a distal end area of the post is connected to an IV bag hook. The post has an offset area between the first end and the second end such that the IV bag hook is positioned over a center of the base. When an IV bag is attached to the IV bag hook, the IV bag is positioned in the offset area so that the post doesn't interfere with the IV bag.
- In another embodiment, an IV holder is disclosed including a base that has a plurality of wheels interfaced to a first side for supporting the IV holder on a floor and allowing movement in a generally horizontal plane. A device for supporting an IV bag hook is interfaced to the base such that the IV bag hook is positioned substantially over a center of the base. The device for supporting is, for example, a post that has an offset area so that an IV bag held by the IV bag hook is not interfered with by the post.
- The invention can be best understood by those having ordinary skill in the art by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:
-
FIG. 1 illustrates a perspective view of an IV holder of the prior art. -
FIG. 2 illustrates a perspective view of a new IV holder. -
FIG. 3 illustrates a perspective view of the new IV holder. -

FIG. 6 illustrates a perspective view of a new IV bag hanger as used with the new or any IV holder. -
FIG. 7 illustrates a perspective view of a new IV bag hanger as used with the new or any IV holder. - Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.
- Referring to
FIG. 1 , a perspective view of an IV holder 1 of the prior art id shown. A typical IV holder 1 has abase 7 withwheels 8 and a substantiallylinear post 2/3/4, shown in this example comprising of alower post 2, a telescoping adjustment lock 3, and anupper post 4. In this configuration, the height of the IV bag 52 (SeeFIGS. 5-7 ) is adjustable to some degree. The top end of theupper post 4 extends outwardly as anarm 5 and thearm 5 terminates in an IVbag hook 6 as known in the industry. - Being that IV
bags 52 are relatively heavy, the IV holder 1 of the prior art is held off balance since the weight of the IVbag 52 is held distal from the center of gravity of the overall IV holder 1. The IVbag 52 exerts an angular force proportional to the height of the IVpost 2/3/4, the length of thearm 5, and the weight of the IVbag 52. - To improve mobility, the IV holder 1 of the prior art is typically made of a light weight material such as aluminum or a light gauge steel, and has
wheels 8. As such, the IV holder 1 of the prior art typically has sufficient mass so as to counteract the above described angular force, remaining stable while the IV holder 1 of the prior art stands on a substantially flat, horizontal surface, but instability occurs during many situations. Instability occurs when moving the IV pole 1 of the prior art, especially when impediments to movement are encountered such as surface changes (e.g. linoleum to carpet), door thresholds, debris on the floor, ramps, etc. When a patient traverses a floor area, such impediments often result in loss of control of the IV holder 1 of the prior art, leading to property damage and potentially bodily harm to the patient and others. - Referring to
FIGS. 2 , 3 and 4, perspective views of a new IV holder are shown. To improve stability, of the IVholder 15 is balanced, reducing or eliminating the angular offset force described in the prior art. In the IVholders 15, the IVbag 52 is suspended in a position that provides less angular force and, therefore, the IVholder 15 is less likely to tip over when encountering impediments as described above. To accomplish such balance, the mass of the IVbag 52 is suspended in a location that is closer to the center of thebase 7 andwheels 8, roughly the center of gravity of the IVholder 15. As shown inFIG. 2 , thesame base 7,wheels 8,lower post 2 and lock 3 are retrofitted with a new upper post/arm 14 which curves outwardly from the center of thebase 7 so that the IVbag hook 6 is positioned roughly central to thebase 7 andwheels 8, at a location that approximately balances the IVholder 15. In this way, the mass of the IVbag 52, hung from the IVbag hook 6 will not place the IVholder 15 off balance, thereby reducing the potential for tipping. Note that it is anticipated that the mass of the upper post/arm 14 will provide a slight angular force (tipping force) in one direction (e.g. towards the left as shown inFIG. 2 ) and, therefore, the IVbag hook 6 is anticipated to be positioned just past center (e.g. towards the right as shown inFIG. 2 ) to balance the slight angular force of the upper post/arm 14. - Throughout the description, the terms “substantially center,” “just past center,” “roughly central to the
base 7,” and “approximately balances” are not exact terms because the exact mass of the IV bag and contents of the IVbag 52 are not constant. Therefore, for design purposes, if the location of the IVbag hook 6 is exactly center to thebase 7, then the IVholder 15 will be slightly off balance when the IVbag 52 is full due to the mass of the outwardly swinging portion of thepost 14/24/34. As the IVbag 52 empties, the IVholder 15 will grow further off balance since the mass of the fluid that was in the IVbag 52 will no longer counteract the mass of the outwardly swinging portion of thepost 14/24/34. On the other hand, if the location of the IVbag hook 6 is offset slightly opposite of the outwardly swinging portion of thepost 14/24/34, the IV holder will be slightly off balance to the side of the IVbag 52 when the IVbag 52 is full, then the IVholder 15 will be balanced when the IVbag 52 is half empty, and then the IVholder 15 will be slightly off balance to the side opposite of the IVbag 52 when the IVbag 52 is empty. - Besides providing improved stability, the IV
holder 15 as shown inFIGS. 2 , 3, and 4 also provides an improved place to grasp, that being the post/arm 14. In the prior art IV holder 1, the patient had to extend an arm further to grasp and had to maneuver around thebase 7 andwheels 8. In theIV holder 15 as shown inFIGS. 2 , 3, and 4, the patient grasps the post/arm 14 and is thereby automatically distant from thebase 7 andwheels 8, reducing interference with walking. Note also that the post/arm 14 provides better protection to theIV bag 52 as the patient maneuvers. For example, if the IV holder 1 of the prior art was pushed up against a wall, theIV bag 52 would hit the wall, while if theIV holder 15 shown inFIGS. 2 , 3, and 4 is pushed up against a wall, theIV bag 52 being roughly centered over thebase 7 andwheels 8 would not hit the wall. - In
FIG. 3 , an alternate design of theIV holder 15 is shown in which the post/arm 24 is one integrated section (e.g., does not telescope). Although the curvature of the post/arm 14 and post/arm 24 are shown having an approximately parabolic curve which is known to have better structural characteristics than, for example, an arc, any shape of post/arm is anticipated including an arc, squared edges, or that shown inFIG. 4 having a flattened post/arm 34. There is no limitation on the shape of the post/arm 14/24/34 and those shown are examples. Any shape of post/arm 14/24/34 is anticipated as long as that shape of post/arm 14/24/34 positions theIV bag hook 6 at a location that provides balance to theIV holder 15 when anIV bag 52 is attached to theIV bag hook 6. - Referring to
FIG. 5 , a perspective view of an IV bag hanger of the prior art is shown. In the prior art, theIV bag 52 is looped onto anIV bag hook 6 as shown, with anIV tube 54 typically extending from the lowest location on theIB bag 52. The hook is directly connected to an arm 50 (similar toarm 5, or any arm 50). As the IV pole (e.g. IV pole 2/3/4) is moved, theIV bag 52 swings on theIV hook 6, creating further instability to the IV holders 1 of the prior art due to the force exerted by the moving mass of theIV bag 52. - Referring to
FIGS. 6 and 7 , perspective views of a new IV bag hanger as used with the new or any IV holder are shown. In bothFIGS. 6 and 7 , theIV hook 6 is interfaced to the arm 50 (e.g. anyarm damper 60/62/70/72. InFIG. 6 , the damper consists of intertwined circular links. A firstcircular link 60 is affixed to thearm 50 and a secondcircular link 62 is affixed to the IV hook. InFIG. 7 , the damper consists of a firstcircular link 70 that is affixed to a rotatingmember 74 and a secondcircular link 72 that is affixed to theIV hook 6. Thedampers 60/62/70/72 dampen swinging motion of theIV bag 52 as shown by arrows inFIG. 6 . - To further improve ease of use as well as safety, in
FIG. 7 , a rotating member 74 (shown as a disc, but there are no shape limitations on member 74) is connected to thearm 50 by abearing 76, allowing theIV bag 52 to rotate as depicted by the arrows shown inFIG. 7 . In some embodiments, the rotatingmember 74 freely rotates with respect to thearm 50 while in other embodiments, rotation of the rotatingmember 74 is limited to less than 360 degrees so as to not twist theIV tube 54. - Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.
- It is believed that the system and method as described and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely exemplary and explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
