This non-provisional application is related to U.S. Patent Application Pub. No. 2012/0118650, entitled DEVICE FOR POSITIONING A CONTAINER FOR A GRAVITY-FED INTRAVENOUS FLUID DELIVERY SYSTEM, published May 17, 2012, the entirety of which is incorporated herein by reference. No claim of domestic priority is being made.
The invention relates generally to suspension systems for intravenous fluid bags, and, more particularly, to portable fluid medicament bag suspension systems.
Gravity-fed intravenous fluid delivery systems (commonly referred to as an “IV Drip”) utilize gravity to deliver fluid from a suspended container to a location that is positioned lower than the container of fluid. Typically, the delivery location is a human being's circulatory system, hence the term “intravenous” wherein a needle is positioned in a vein on a person's arm or leg wherein substances are delivered directly into a vein. Therapies administered intravenously are often called specialty pharmaceuticals and may be commonly referred to as a drip because many systems of administration employ a drip chamber (e.g., a suspended container), which prevents air entering the blood stream (air embolism) and allows an estimate of flow rate. Intravenous therapy may be used to correct electrolyte imbalances, to deliver medications, for blood transfusion or as fluid replacement to assist with, for example, dialysis. Compared with other routes of administration, the intravenous route is a fast way to deliver fluids and medications throughout the body.
With rising healthcare costs, more and more treatments are being performed on an outpatient basis rather than an inpatient basis. Typical medical procedures which now may be performed on an outpatient basis include rehydration of patients suffering from diabetes mellitus and peritoneal dialysis in which the peritoneal cavity is used as a fluid retention reservoir to perform dialysis without the necessity of a dialysis machine. Such procedures must be performed three to four times per day on an ongoing basis. Thus, a conventional suspended intravenous pole, typically on wheels, may not be suitable for use in the home environment or for travel. With a suspended container, a conventional manner of suspending the container may be using an IV drip stand. An IV drip stand may include a base that supports a pole that extends high enough in a vertical direction such that a suspended container may be suspended higher than the intravenous injection point in the person receiving therapy. The IV stand, however, is cumbersome and bulky as it must necessarily be tall enough to suspend the fluid container higher than a person's arm or leg. Sometimes, one can wheel the IV stand around if the base has wheels. Further, sometimes, the IV pole may be mounted directly to a bed where the person must remain when receiving therapy. In these cases, a problem exists wherein the IV stand is less mobile in that the IV stand cannot be easily transported in a vehicle or airplane. An IV pole attached to a bed is worse for portability as very few vehicles or airplane can accommodate a hospital bed. Cumbersome and bulky IV stands are difficult to deal with when portability is needed.
Alternative to wheeled IV poles are disclosed in various prior references. Adair discloses a portable intravenous device and hanger therefore in U.S. Pat. No. 8,567,738, issued Oct. 29, 2013, directed to veterinary field calls. The device includes a bracket which may be secured to a structure, presumably a wall section or door. Nevertheless, the device is complex, expensive to manufacture and sell, and not well-suited for a temporary or occasional home use.
U.S. Pat. No. 3,966,160, issued on Jun. 29, 1976, to Wilson discloses an inflight intravenous bottle holder for use with stacked litters such as in a life flight aircraft. The device is adapted to be vertically adjustable on vertical poles which interconnect the various litters. Wilson's device is not suitable for home use.
My own device for positioning a container for a gravity fed intravenous fluid delivery system was disclosed and published in US patent application 2012/0118650, published on May 17, 2020, titled, “Device for Positioning a Container for a Gravity Fed Intravenous Fluid Delivery System” resolves many issues and limitations of the herein above discussed prior art references. My device described in said publication is a simple unitary structure having a leg portion which can reside against the back of a door and an integral leg portion which resides on top of the door, leading to an extended frame leg from which an intravenous fluid bag may be mounted. Although the device is inexpensive and relatively light weight, it is cumbersome and does not pack well for travel. An attempt to avoid and overcome these difficulties is shown in an alternative embodiment of the invention where the various legs are interconnected by hinges so as to make the device foldable. However, such hinges are expensive to manufacture and may compromise the rigidity of the device while holding e.g. an IV bag. The result of such a device collapsing while intravenous fluid is being administered is significant. It may be impossible to know at that point how much of a dose has been metered. Moreover, when the bag impacts e.g. the floor, air may be introduced into the intravenous fluid line connected to the patient resulting in a dangerous embolism. Therefore, a need exists for a portable intravenous fluid bag suspension device which is inexpensive to manufacture, highly portable, yet extremely rigid and resistant to collapse when suspending an intravenous fluid bag.
It is therefore an object of the present invention to provide for a fluid medicament bag suspension device which is extremely rigid and, yet, may be disassembled for easy transport. It is a further object of the invention to achieve the above object with the device which is inexpensive to manufacture and easy to assemble.
The invention achieves the above objects and advantages, as well as other objects and advantages that will become apparent from the description which follows by providing a portable fluid bag suspension device having an elongated strap, defining inner and outer surfaces, and first and second distal ends. The outer surface has a first tab extending therefrom intermediate the distal end and a second tab extending from one of the surfacing proximal to the second end and adapted to pass over a portion of a door or a drawer. The inner surface of the strap further has a first and second open end pockets positioned on opposite sides of the first tab for receiving a stiffening member having first and second legs disposed at an acute angle with respect to one another for respective receipt in the first and second pockets. An aperture is provided on the first tab for removal receipt of e.g., an IV bag. The legs of the stiffening member may be received in the corresponding pockets and the second tab placed behind a closed door or drawer so that the strap second distal end abuts an obverse side of the door or drawer. The received first leg will thus suspend the aperture on the first tab in free space away from the door or drawer, with the received second leg pressing against the exposed side of the door or drawer. In preferred embodiments of the invention, the stiffening member is removably received in the pockets so that when removed therefrom, the stiffening member may be conveniently packed in the corner section of a valise or a suitcase while the flexible main body may be adapted to any structure or items within the bag or valise. In the preferred embodiments of the invention, the acute angle on the stiffening member is in a range of approximately 40 to 60 degrees and preferably approximately 45 degrees. The main body is preferably manufactured from a flexible material such as textile and has an overall length of approximately 14.5 inches and a width of approximately two inches.
Preferred and alternative embodiments of the present invention are described in detail below with reference to the following drawings.
A portable intravenous (hereinafter “IV”) fluid bag suspension device in accordance with the principles of the invention is generally indicated at reference number 10 in the various Figures of the attached drawings, wherein numbered elements in the Figures correspond to like numbered elements herein. As used herein, the terms “IV fluid bag”, “fluid medicament bag”, “IV bottle” and the like refer to and mean any fluid medicament container which is inverted for gravity feed of the medicament fluid therein for use in association with medical treatments.
As best seen in
When received in the first and second pockets 20, 22 the first and second legs 26, 28 of the stiffening member 24 provides rigidity to the otherwise flexible main body 12. This permits the second tab 54 of the main body to be placed behind a door or drawer 60 such that the second tab 54 resides against an obverse side 62 of the door while a portion of the main body adjacent to the second tab 54 resides on a top portion 64 of said door. When the door or drawer is closed, the second tab 54 will be captured there behind, and the free end 38 will abut against a front surface 66 of the door or drawer when the door or drawer is closed. In this manner, the first tab 44 carrying the gromet 48 will be suspended in free space at least 4 inches away from the door allowing the intravenous fluid bag 52 to be suspended therefrom without touching the door. Such suspension of the bag in free space is important to the free flow of medicament within the bag through the VI tube (not shown) to the patient. Such free suspension is also important if a weight scale is used for purposes of metering the dose such that the weight is not partially carried by the front surface 66 of the door or drawer rendering an inaccurate weighing.
The suspension device 10 described above advantageously permits a user who may have to perform an outpatient procedure such as peritoneal dialysis three to four times per day with the opportunity to suspend the fluid medicament bag 52 from a hotel door or drawer while traveling. The stiffening member 24 is readily removed from the first and second pockets 20, 22 so that the stiffening member may be positioned in a corner of a suitcase or valise while the flexible main body 12 is folded up and neatly placed therein as well. The removable capability of the stiffening member 24 advantageously permits the main body 12 to be used in an alternate embodiment and method wherein the main body 12 is directly suspended from a coat hook or the like in a dwelling or hotel room without the use of the stiffening member. This may be the case where the main body is suspended far enough away from the wall or other support member by the coat hook or the like so that the fluid bag is relatively located in free space and not against a support.
It should be apparent to those of ordinary skill in the art that modifications may be made to the preferred embodiment of the invention without deviating from the spirit and scope of the invention itself. For example, the second tab 54 may be constructed so as to be directed from the outer surface 16 of the main body 12 rather than the inner surface 14 as shown in
Thus, the invention is not to be limited by the above disclosure but determined in scope by the Claims which follow.
