.11 llll lllllhlllLd 'IIIIA 28 INVENTOR M QTH J LDA c. FRANK Jul L'aHY-A TORNEYS DRAINAGE BAG HOLDER SHIELD AND METHOD BACKGROUND OF THE INVENTION 1. Field This invention in general relates to medical appliances and more particularly tonovel and improved bag holder shields for supporting drainage bags applied to a patient following certain surgical procedures.
2. Description of the Prior Art Following certain surgical procedures it is necessary to mount a disposable drainage bag on the body of a patient to receive draining body fluids via the stoma which extends through the outer wall of the abdomen. Appliances of this type may also be used for fistulas and all body drainage due to injuries or tumors. It is also highly desirable to provide an effective. airtight seal between the body and the bag holder shield and between the stoma and the bag holder shield to prevent the release of undesirable odors. The portion of the shield which engages the skin and stoma can cause great discomfort if it does not flex properly. At the same time a degree of rigidity is required to support the depending bag. For some patients such as those which are obese a greater degree of rigidity is required to hold the bag. For other patients a greater degree of softness is required. A number of approaches have heretofore been used to secure a drainage bag to the body of a patient and many attempts have been made to minimize the discomfort to the wearer and provide ease of removal and replacement of both the shield and bag. In the past a wide variety of structural configurations and materials have been attempted for making up the bag holder shield but as yet they have not been entirely satisfactory for all patients. Accordingly, it is an object of this invention to provide novel and improved bag holder shields which overcome many of the above-mentioned deficiencies in the prior art to make them suitable for a wider range of surgical appliances and patients.
Another object of this invention is to provide novel and improved bag holder shields having an improved configuration and made of molded flexible materials which afford improved results in wearer comfort, do not irritate the skin, prevent injury to the stoma or other drainage tube of the wearer, and are highly effective in supporting of a drainage bag.
Yet another object of this invention is to provide a novel bag holder shield which is resistant to weak acids found in body secretions, resistant to oils and will not swell ordeform after extended body contact or cleaning with hydrocarbon solvents or the like.
Still another object of this invention is to provide a novel bag holder shield which is readily secured on the skin of the patient and may be removed and replaced so that it may be reused many times.
SUMMARY OF THE INVENTION In accordance with the present invention in the preferred embodiments shown there is provided a bag holder shield of a symmetrically balanced, generally oval-shaped configuration made of a relatively soft, compression-molded thermoplastic resin which has a sufficient degree of rigidity to enable use by more obese patients; and in another form there is provided a shield of a similar configuration made of a relatively soft, transfer-molded thermosetting elastomeric material which is suitable for more average patients and has a greater degree of softness. Each of these shields are in the form of an integral member made entirely of the same flexible molded material throughout having a relatively thin flat base section with a smooth flat undersurface adapted to be placed over and secured to the skin and conform to the contour of the wearers body. The base section includes a generally circular central portion and tapered end portions. The integral member is made to be symmetrical about both the major and minor axes of the oval shape and terminates in generally rounded outer edges. A central flange section projects outwardly from the central portion of the base section and is arranged concentrically thereof to provide an area of greatest thickness outwardly around the center of the integral member. The flange section has a concave peripheral edge and a dished outer face which progressively decreases in cross section toward the center. The center portion is formed by a relatively thin section in which an opening may be cut to size to receive the stoma for each particular patient or formed with a small opening which may be cut to a larger size. The outer end portions of the body are provided with loops through which the ends of a support belt extend and are secured to provide support for the shield on the wearer.
Other objects, advantages and capabilities of the present invention will become more apparent as the description proceeds taken in conjunction with the accompanying drawings in which:

DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to the drawings, in FIGS. 1-3 there is shown one form of bag holder shield made as an integral member 11 entirely of a compression-molded, thermoplastic resin described in more detail hereinafter. The shield is generally oval-shaped and includes a relatively thin, flat base section 12 and a smooth flat undersurface 12a adapted to be placed over the body of the wearer and conform to the curvature thereof. The base section 12 includes a generally circular, wider central portion 12b and a pair of outwardly converging ear-like narrower end portions which terminate in generally rounded outer edges 13. The shield is constructed to be symmetrical about both the major and minor axes of the oval shape. The shield also includes a central flanged section 15 projecting outwardly from the base section and arranged concentrically with the center thereof to provide a bag-supporting annulus of maximum thickness surrounding and outwardly spaced from the center of the member. The flanged section annulus has an overhanging lip portion 15a and a concave peripheral edge 15b and is also shaped with a straight flat outer portion 15c parallel to the bottom surface 12a, an inwardly extending dished outer portion 15d which converges toward the center of the member and terminates in a flat, central portion 16 of minimum thickness. The shield member also has an inwardly extending step 17 in the undersurface between the center and outer edge of the body which further reduces the thickness of the central portion 16.
In the use of the shield a hole is cut ofa desired diameter for a particular patient in the central portion 16 through which a stoma 18 from the wearers body is passed to discharge body fluids into the supported bag 27. The stoma is a portion of the bowel brought through an outer wall of the abdomen by the surgeon. The bag holder shield and associated bag or pouch 27 act as an external collecting device to collect urine or feces. The shield is also used for fistulas and all body drains due to injuries or tumors. A U-shaped portion 19 is provided with an outer surface of each end portion to provide a loop which the ends of a support belt may extend to further secure the shield to the body of the patient.
The shield 11 is molded as a one-piece integral unit or body made of arelatively soft thermoplastic resin which affords a highly desirable degree of flexibility to conform to the contour of the body and prevent injury to the stoma, adequate-rigidity and sufficient softness for maximum comfort to the wearer. The shield flexes at the ends so as to be readily removed and reused and the annulus is sufficiently thick to afford an adequate support for the depending drainage bag. The central portion 16 can be cut to the desired size to fit the stoma of each individual patient.
The typical physical properties of the shield shown in FIGS. l-3 are in the range of about:
Durometer3244 Shore A, (38 Shore A nominal) Tensile-1440 psi-l 575 psi Elongation-540-660% Tensile Modulus 0.02 X 10 psi 0.12 X psi The above values are taken using the ASTM Standard No. 638.
As represented in FIG. 3, the above-described shield may be attached to the skin 20 of a patient by first making a center aperture in portion 16 through which the stoma 18 will extend and of a size so that the walls defining the aperture engage the sides of the stoma. A
layer of medicament such as karaya powder represented at 21 is applied directly to the skin 20 and a liquid seal coating is applied over the medicament which dries to form a flexible film base 22. A coat of rubberbase adhesive is then applied to the base 22 to form an adhesive layer 23. The undersurface of the shield 11 is precoated with the liquid seal coating to form a layer 24. The details of the liquid seal coating and the procedure to secure the shield to the body are described in more detail in a copending application entitled FLEXI- BLE FILM-FORMING LIQUID AND METHOD FOR APPLYING SURGICAL APPLIANCES.
An alternative form of bag holder shield shown in FIGS. 4-6 is also formed as an integral or one-piece member 31 but this form is made entirely of a thermosetting elastomeric, non-plastic, transfer-molded flexible material. The shield includes a relatively thin, flat, flexible base section 32 with a smooth flat undersurface 32a to be placed over the body of the patient and conform to the curvature thereof. The base section includes a generally circular central portion 32b and a pair of outwardly converging narrower ear-like end portions 32c on each side of the central portion and terminate in generally rounded outer edges 33. The shield is generally oval-shaped and symmetrically balanced about both the major and minor axes thereof. The shield also includes a central flanged section 35 projecting forwardly and outwardly from the base section and arranged concentric to the center thereof to provide a bag-supporting annulus of maximum thickness surrounding and outwardly spaced from the center thereof. The flanged section has an overhanging lip 35a and an outer concave peripheral edge 35b adapted to receive the end of the bag together with a flat outer section parallel to the undersurface and a dished outer portion 350 which inwardly converges toward the center of the body and terminates in a flat portion 35d of minimum thickness surrounding a central opening 36. The central opening is small enough so that it may be cut to the required stoma size. A U-shaped portion 39 is provided on the outer surface of each end portion to form a loop through which the ends of the support belt extend to further support the shield on the body of a wearer.
The bag holder shield 31 is secured to the patients body in the same manner as that above described in FIGS. 1-3. The shield of this arrangement is molded as a one-piece integral body of a material somewhat softer and less rigid than that of FIGS. 1 through 3 and affords use more by patients that are not obese and require less rigidity and greater softness. The material used for this shield is a homogeneous blend of: (1) A polymer or polymers such as a blend of Nitrile Rubber and Polyvinyl Chloride (PVC). This blend is well suited because ofits resistance to weak acids found in body secretions. It is also very resistant to oils and will not swell or deform after extended body contact or cleaning with hydrocarbon solvents. (2) Inert fillers such as Barium Sulfate and Silica which are added to control the hardness; and (3) Organic Accelerators and sulfur used to control the time and temperature of the molding.
The typical physical properties of the shield shown in FIGS. 4-6 are in the range of about:
Durometer-7O Shore A Tensile-l360 psi-1660 psi Elongation540660% Modulus-775 psi-865 psi The material which exhibits these characteristics and found suitable for this configuration is presently being made by the US. Industrial Chemicals and identified under code UE-636. The above described materials so far as known have not heretofore been used to provide a bag-supporting shield on the body of a patient and are therefore believed to constitute a new use thereof.
Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made by way of example and tha changes in details of structure may be made without departing from the spirit thereof.
