United States Patent 3,422,463 URINAL ASSEMBLY Clyde E. Lowry, P.0. Box 2900, Little Rock, Ark. 72203 Filed Oct. 27, 1966, Ser. No. 589,880 U.S. Cl. 4-110 Int. Cl. A47g 9/00; A47k 11/12 Claims ABSTRACT OF THE DISCLOSURE This invention relates to urinals for use by bedridden persons and more particularly to a disposable self-serving urinal assembly of this general type.

Urinals of the type commonly employed in hospitals for use by bedridden patients are not entirely satisfactory in that they are highly susceptible to spilling, both during and after use, and normally require the attention of the orderly immediately after each use, as well as to bring the utensil to the patients bed. Further, these prior art devices, which are normally made from a. durable material such as stainless steel, normally must be emptied through the open top and require cleaning and sterilization after each use. This cleaning, sterilization, and redistribution of the devices is a time consuming operation and requires installation, operation, and maintenance of expensive cleaning equipment. Thus, the initial relatively high cost of the known devices is greatly increased by the cost of the frequent cleaning, sterilization and distribution of the devices to the patients in a hospital. For home use, the known devices present even greater problems in that the necessary equipment for adequate cleaning and sterilization is not readily available. It is therefore a primary object of the present invention to provide a disposable urinal assembly for use by bedridden patients.

Another object is to provide an improved self-service, disposable urinal assembly which may be used by bedridden patients without requiring the assistance or attention of an orderly and which minimizes the likelihood of spilling both during and after use.

Another object is .to provide such a urinal assembly which may be used by one patient for as long as required and then entirely discarded.

Another object is to provide such a urinal which automatically empties into a disposable drainage bag and which may be used more than a single time before emptying of the drainage bag is required.

In the attainment of the foregoing and other objects, an important feature of my invention resides in employing an open-topped receptacle having a drainage opening in the side wall thereof adjacent the bottom of the receptacle, with a fitment secured in fluid tight relation in the opening and releasably retainingone end of an elongated flexible drainage tube in fluid communication with the interior of the receptacle. The other end of the drainage tube extends through an opening in the top of a plastic drainage bag adapted tobe suspended from the rail on the side of a bed. The open-topped receptacle is provided with a handle which also serves as a hanger for supporting the receptacle on the side of the bed in position where it is readily accessible for unassisted and unattended, repeated use by the patient.

The open-topped receptacle is preferably formed from 3,422,463 Patented Jan. 21, 1969 a synthetic resin material which is inert to uric acid and other chemicals, normally present in urine. Numerous relatively inexpensive synthetic resin materials are now commercially available which meet these requirements and which may be readily molded by commercial methods and equipment commonly employed to mold conventional, disposable plastic containers such as those commonly employed to package liquid detergent or the like.

Other objects and advantages of the invention will become apparent from the following detailed description, taken with the drawings, in which:

FIG. 1 is a perspective view of the urinary receptacle employed in the invention;

FIG. 2 is an elevation view of a urinary drainage bag and drainage tube suitable for the use in the invention;

FIG. 3 is a fragmentary sectional view taken on line 33 of FIG. 1 and illustrating the manner in which the drainage tube is secured to the receptacle; and

FIG. 4 is a perspective view illustrating the urinal assembly supported on the side rail of a hospital bed continuously accessible for self-service use by the patient.

Referring now to the drawings in detail, the urinary receptacle 10 employed in the present invention is illustrated as a unitary molded plastic container including substantially cylindrical body portion 12, an opentopped neck portion 14, and a transition portion 16 connecting the neck and body. A handle 18 is integrally molded with the receptacle and extends outwardly from the neck and transition portion, then downwardly in parallel spaced relation to the body portion. As illustrated in FIG. 4, the handle serves as a hanger to support the receptacle from a bed rail with the container inclined or tilted away from the handle.

An opening 20 is formed in the side wall 22 of the body portion 12, adjacent the bottom wall 24 thereof, as best seen in FIG. 3. A molded plastic, cylindrical, plugtype fitment 26 having an axial opening formed therethrough is mounted within opening 20. Preferably, side wall 22 is thickened in the area of opening 20 to support fitment 26 along its entire length and to permit fluid in the receptacle to be completely drained therefrom through the axial opening when the receptacle 10 is tilted toward opening 20. A radially extending flange 30 integrally formed on the outer end of fitment 26 engages the outer surface of side wall 22 and a shoulder 32 extending upwardly from bottom wall 24 engages the inner end as at 40. The outer tubular element 36 of fitment 2 6 has its outer surface in contact with and preferably bonded to the inner surface of the opening 20 and the inner tubular element 38 forms, in effect, an outwardly directed male nipple adapted to be inserted into the open end of an elongated flexible plastic drainage tube 42. Preferably the outer diameter of the inner tubular element or nipple 38 and the inner diameter of the outer element 36 are substantially equal to the inner and outer diameter, respectively, of the tube 42 so that when the end of the tube is inserted into the recess 34, it will be frictionally engaged on both its inner and outer surfaces. Thus, with a relatively short nipple 38 inserted into the open end of tube 42, the tube is finmly but releasably retained on the fitment. Since the nipple 38 is recessed into the receptacle, stresses on the short nipple as a result of bending of the flexible tube during use or other handling of the device are virtually eliminated by the support from the outer tubular element 36 and the relatively rigid side wall 22.

The other end of the elongated flexible tube 42 is received in an opening 44 at the top of a fluid tight flexible plastic drainage bag 46. The drainage bag is preferably formed of a relatively thin tubular thermoplastic material heat sealed as at 48, 50 along its bottom end. Also, a pair of spaced heat seals 52, 54 are formed across the top portion of the bag, with the lower seal 54 terminating at a point spaced from one side edge of the bag to permit the tube 42 to be inserted therein. The spaced seals 52, 54 form a tubular hem for receiving a semi-rigid support member 56 for hanging on a suitable hanger member 58 on the rail of a bed, as illustrated in FIG. 4. An arcuate cut-out portion 60 provides easy access to support member 56. Markings may be provided on the side surface of the drainage bag to indicate the approximate volume of the contents of the bag.

The plastic drainage bag 46 and drainage tube 42, per se, are conventional items commonly used in the hospitals in connection with drainage pumps, catheters, or the like, and such drainage bags and tubes may be purchased on the open market, either separately or with the bag containing a drainage tube packaged therein as illustrated in FIG. 2 of the drawings. However, the use of these known drainage tubes and bags in combination with the novel urinary receptacle disclosed herein provides a new and useful urinal assembly which avoids many of the problems accompanying the known devices. For examples, the problem of spillage, either during or after use, is virtually eliminated, and the attention of an orderly is no longer needed except for periodic emptying of the drainage bag.

In practice, one end of the tube 42 is withdrawn from the drainage bag 46, through opening 44, and attached to the receptacle by pushing the open end of the tube onto the nipple 38. The bag is then hung on the rail of the bed, at any convenient place, and the handle 18 of receptacle 10 is hung over the bed rail at a position readily accessible to the patient. The urinal assembly is then selfserving in that it may be repeatedly used at will by the patient wtihout assistance from the orderly. The receptacle 10 automatically empties itself during and/ or after each use by draining into the bag 46. After use, the patient merely hangs the receptacle 10 on the rail of the bed in position Where it is readily reached, Without assistance, when again needed. The orderly may then, at regular scheduled intervals, check the assembly and, if necessary, empty the drainage bag.

Since the receptacle 10 is drained after each use, it is not necessary to replace this receptacle each time the drainage bag is emptied. Indeed, for hospital use, a single assembly may frequently suflice for the entire period which the patient is bedridden, at the end of which period the entire assembly is disposed of. Thus, an individual patient in a hospital will always use the same assembly, until it is finally disposed of, so that sterilization and/ or replacement of any or all parts of the assembly after each use is not required.

The receptacle 10 provides a reservoir at bed-level to compensate for variance between the rate at which the container is filled and the rate at which it may be emptied through the plastic tubing attached to the drainage opening. Drainage takes place during use and is completed by lifting the receptacle by the handle which is arranged on the side of the receptacle opposite the drainage opening. Thus, the receptacle is always automatically emptied before it is hung on the bed rail.

While I have disclosed a preferred embodiment of my invention, 1 wish it understood that I do not intend to be restricted solely thereto, but that I do intend to cover all embodiments thereof which would be apparent to one skilled in the art and which come within the spirit and scope of my invention.
