Description

 The invention relates to bags for receiving fluid and, in particular, a disposable bag for receiving fluids from the human body, such as urine, blood, vomit.

 The present invention relates to the problem of providing collection and removal of fluid from the body, in particular liquid waste other than bathtubs, collecting and sanitary equipment.

 There are many situations in which he or she feels the need to urinate, but in the absence of any conventional toilets. Telephone and cable network workers can work in underground hatches and tunnels and do not have access to the toilet without having to leave the workplace and go to the public toilet. Similarly, telephony workers or electricians very often work in areas remote from the restroom and must also stop working and head to a remote toilet several times a day for their natural needs. In the past, it was a common practice that an employee working in a remote or closed area had no choice but to find a suitable place in the work area and urinate there. However, this situation is very unsatisfactory, since it violates many of the wishes for health and the environment, which in recent years have become more relevant.

 Similarly, pilots and passengers of many types of civilian and military aircraft do not have regular access to the toilet for extended flights. The problem, in particular, is acute for military pilots, who must perform long flights in very cramped conditions and at the same time must always be on alert to be able to instantly repel hostile actions. Of course, the military was aware of this problem, and the naval and ground pilots were supplied with one of these types of urine collection bags made of material such as a sponge designed to hold liquid. However, it was found that very often a significant amount of urine leaked from these bags, especially when the pilot performed air maneuvers.

 The need for a convenient way to safely and reliably collect and retain liquid body waste in order to dispose of it is also obvious in other cases. Those who suffer from motion sickness in vehicles, such as cars and airplanes, need a good container to collect and remove vomit resulting from motion sickness.

 In various situations, medical staff often have to dispose of a significant amount of the patient’s blood in surgery, trauma centers or emergency rooms where patients may have heavy bleeding. The current practice of using open blood collection containers has been unsatisfactory.

 In addition, there are cases that do not really concern the “waste” of the body, but when the body fluid is collected, for example, for analysis and research, such as the collection of urine or blood.

 Therefore, there is an urgent need for a convenient and practical bag for collecting and localizing liquid waste, which is easy to use in a confined space and which would ensure reliable and complete absorption and liquid content even under the influence of external forces, which otherwise could lead to liquid splashing, and which can be conveniently and safely thrown away.

 The present invention relates to a disposable bag for receiving body liquid waste, which includes a bag having an internal cavity formed by two sides meeting at opposite edges; bottom and top with edges and a sealed bottom, the top being made at least partially open to receive liquid body wastes; hydrophilic material inside the bag that gels quickly upon contact with the liquid waste entering the bag; closing means to close the top of the bag after the liquid waste enters it.

 A hydrophilic material is a polymer that activates upon contact with water or water-based fluids (e.g., body fluid waste) and quickly forms a gel (usually within thirty seconds or less) to sequestrate liquid waste. Most preferably, the hydrophilic material is part of a mixture of materials that may contain enzymes, deodorants, flavors, abnormalities of the human body, and / or pregnancy rates. The material may be in any of various physical conditions, for example, in powder, granules, fibers, mats or foam.

 In its various embodiments, the bag may be rectangular or have a different shape to adapt to the needs of users, such as an L-shape, which is convenient for civil aviation pilots. In addition, it can be adapted to be worn by the user, for which it is attached to the user's leg, and the catheter is inserted into the urinary organs, as a result of which therapeutic patients and people suffering from urinary incontinence can be treated on an outpatient basis.

 The structure shown in FIG. 1 is a typical structure of a disposable body liquid waste bag of the present invention, denoted generally by 10. This bag is preferably made of a lightweight plastic material that is impermeable and thick and strong enough to withstand accidental punctures under normal conditions. handling it. The bag, in its preferred embodiment, as shown, has a substantially rectangular shape made of one or two sheets of plastic, for example polyethylene, vinyl, mylar or the like. The two-sheet version contains opposing rectangular sheets 12 and 14, bonded or glued together at their three peripheral edges, for example, by thermal insulation or another type of gluing, forming seams along the side edges 16 and 18 and the lower edge 20, leaving the upper hole 21, as shown in FIG. .2 and 3. In addition, the bag can be made of one sheet and folded along one side so that the bottom with the sides are subsequently sealed to leave an upper opening 21.

 Inside the bag, as shown in FIGS. 1, 8 and 13, there is a funnel containing two opposite sheets 22 and 24, connected together at the seams 26 and 28 and going down from the top hole of the bag to the hole 30 leading to the inner cavity 31 of the bag. Or the funnel can be formed from one sheet of the corresponding shape, folded and sealed so as to have an upper hole 33 and a lower hole 30. Regardless of whether the funnel is made of separate sheets or from one sheet, the upper hole 33 has the same length with the upper hole 21 bag.

 If necessary, the sheets 22 and 24 can be a continuation of the side panels 12 and 14, as a result of which the panels forming the sides and the funnel are formed from one sheet into the shape of two rectangular side panels 12 and 14 located side by side with the rectangular panels 22 and 24 going from above. Then the panels are bent near the edges 16 and 18, and the panels 22 and 24 are bent through the stiffener 32 and the panels are thermally insulated along the edges 18 and 20 below the stiffener and along the edges 26 and 28 of the panels 22 and 24.

 Although the bottom hole 30 of the funnel, extending into the inside 31 of the bag 10, is shown in FIG. 1 centered, however, it can be at any point between sides 16 and 18. For example, in FIG. Typically, for general use by both men and women, the opening 30 will be located in the center of the bag, however, variants of the bag designed for special occasions or for use by one of the sexes may have the opening 30 correspondingly offset.

 Around the hole 21 at the top of the bag 10 is a stiffener 32, made in the form of an arc or loop. The arc shown in FIG. 2 is an elongated element made, for example, of a corresponding piece of flexible plastic having sufficient memory so that when it is curved in an arc shape, as shown in FIG. 2, it seeks to displace the upper edges of the panels forming the sides of the panels outward, thereby acting as a crank arm and keeping the bag open. The arcuate stiffener 32 is also involved in supporting the bag. The stiffener 32 is conveniently held in position by wrapping the upper edges of the bag to form elongated cylindrical sleeves 35 into which the stiffeners 32 are placed. For many variants, the stiffener 32 will be sealed in position by closing the open ends of the sleeves 35, for example by thermal insulation. Or, as shown in Fig. 8, the stiffener 32 can be made of two separate parts having a U-shape. Two parts are inserted respectively from opposite ends into sleeves 35 and are located to each other with their front ends 37, while either touching or next to each other. This allows you to remove the stiffeners 32, if the user wants. It also allows you to replace the stiffener in case of breakage before using the bag.

 A convenient holding means in the form of a metal loop or ring 44 can be made in the upper corner of the bag near the top to ensure that the bag is gripped and held while the clip is attached to it or while using the bag. Ring 44 is firmly attached to the bag and forms a strong and rigid grip structure.

 One embodiment of the bag closing means comprises a clip 34 extending along the upper opening 21 of the bag immediately below the upper rim formed by the sleeves 35. The clip 34 is an elongated plastic or metal pipe provided with a slot 39 extending along the entire length of the clip and having opposing jaws 36 and 38 for gripping and displacing the two sides of the bag together in tight interaction with each other. The ends of the slots 39 have bevels 40 to facilitate sliding of the clamp 34 along the upper edge of the bag 10. The clip is mounted on the bag 10 by gripping an edge 16 or 18 on the bevel 40 directly under the sleeves 35 and the stiffening element 32 and then sliding the clip 34 on top of the bag 10 .

 Wherever possible, and in particular along the top 21, it is desirable to have rounded seams in order to ensure ease of use and to prevent skin irritation of the user during contact with the bag.

 Another embodiment of bag 10 and means for closing it are shown in FIG. The bag has an L-shape with a pronounced depression 11 made on the edge 18, while the other edge 16 is angled to form an L-shaped. This shape of the bag can be conveniently used by military pilots who are restricted in their movements by the enclosed limited space of the cabin. In FIG. 8 also shows another shape of the bag closure, which is in the form of a zipper 43 formed by a longitudinal rib 45 cooperating between two opposing longitudinal ribs 47 to form a seal. Only a type of seal that does not require the use of a clamp 34 is suitable, in particular, for use in bags on vehicles, namely cars and aircraft, due to the ability to integrate the sealing means directly into the bag structure and thereby avoid the need for a separate clamp. This is especially desirable for military aircraft, where the pilot's attention should not be distracted to ensure that the separation of the bag and the clamp.

 8-10, alternative means for gripping a bag by a user are shown, which include adjacent sides 51 and 53. These in turn are upwardly extending sheets 22 and 24 that extend up and out from hole 21. These sides 51 and 53 can be turned down, as shown by the dotted line in FIG. 9 (51 and 53, respectively). The large sides 51 and 53 form a large surface that the user can easily grab in cases where otherwise it is not convenient, or it is easy to hold the bag. For example, for a military pilot with gloved hands, it will be easier to capture these protruding surfaces than any other exciting means, for example, ring 44. It is also assumed that such large surfaces will be convenient for children, women and people with physical disabilities. deficiencies, such as with arthritis of the hands.

 Another embodiment of the clamp 34 is shown in FIGS. 11 and 12. This embodiment of the clamp 34 includes an inner tongue 49 that extends downward within the cylinder of the clamp 34 and interacts with an edge 16 or 18 and the external curvature of the stiffener 32 when the clamp 34 moves to one side of the bag . This prevents the clamp from being removed from the bag, and also provides an effective handle in its extended state that the user can grip when using the bag.

 Another embodiment of the bag 10 is shown in FIG. 13, in which all sides 16, 18 and 20 are sealed and the top 21 is sealed almost along its entire length, in which only a small hole, preferably located in the center, is left to receive the tube 57 ( which typically comprises a one-way valve 59) which, with its upper end 61, is connected or integrated with a catheter (not shown) leading to the urinary tract of the user. Bag 10 in FIG. 13 can be attached using straps 63 and 65 to the user's leg. Thus, patients with incontinence or after surgery, and other patients requiring urine drainage, can now be treated on an outpatient basis.

The bag preferably has a capacity to store about 300-600 cm ^{3 of} liquid. This is more than enough to satisfy a one-time natural human need. However, if necessary, the bag can be made larger, but then in this case it will be difficult for the user to carry it. Small bags are not recommended because they do not have a sufficient volume adequate to the natural needs of a person, except possibly with bags for children.

 Bags 10, as noted above, are usually made of impervious flexible plastic material. Usually they are opaque, due to the material itself or the dye, which is added to the composition of the plastic. Or, as shown in FIG. 9, the bag can be made of transparent plastic so that the contents can be seen. In particular, this is advisable in medicine when a nurse or doctor needs to monitor the patient's urine in order to identify symptoms of abnormalities. In addition, it is of particular importance for military pilots, who should be able to monitor the appearance of blood in the urine, indicating internal damage after the battle. It is also desirable that the outer sides of the bag be soft, or, in other words, comfortable material for those cases when the bag in Fig. 13 is in continuous contact with the skin of the patient.

 Inside the bag is and is essential for the functioning of the present invention, a certain amount of absorbent 42 to absorb the liquid contained in the bag. Absorbent 42 contains a hydrophilic gelling material, usually a polymer that activates under the influence of water and quickly forms a gel (usually within 30 seconds and more often much faster) when in contact with an aqueous liquid (such as urine or blood) and which completely absorbs due to gelation and covers the entire liquid with the capsule. Such polymers are commercially available and are often found in various well-known products, including disposable towels and cleaning compositions.

 Typical examples include acrylonitrile-based polymers described in Elias Mega Molecules, p. 157-158, 1987. Mixture 42 is preferably a complex mixture, including not only a gel-forming material, but also a material, such as an enzyme protease, for affecting and destroying urine, blood and other liquid wastes in order to enhance the effect of the gel-forming material. Mixture 42 may also include deodorants and flavoring agents. In addition, biocidal or antiviral material may be included when it is contemplated that liquid waste may be infected, for example, by collecting blood in an operating room or during other medical manipulations with a patient. The mixture 42 may be in any convenient physical form placed in the bag 10, namely granular, powder, foamed, braided and fibrous. We have successfully used granular material sold under the Sanwet trademark IM-5600 from Hoechst Celanese Superab sorbent Matorial Divison, Portsmoutb, Viegin, which is described as starch grafted sodium polyacrylate. This product is suitable, however, not only the composition of the components, but also their formula are unknown to the applicants. The product showed itself well in the tests for gelation and isolation of all liquid wastes placed in a test bag, which lasted no more than twenty seconds.

 In the case of blood collection, it may be desirable to include in the mixture 42 one or more control materials which, when in contact with the blood, would produce visible color changes indicating specific blood disorders or the presence of specific microbes in it. Similarly, when collecting urine, you can also include materials in a mixture of 42, which with a similar color change will indicate an infection in the urinary tract, internal disorders, as evidenced by symptoms in the urine or the presence of microorganisms in it, such as bacteria or viruses. In addition, you can also include well-known pregnancy indicators of this type, which are usually used in the home pregnancy determination kit, as a result of which the bag used by the woman to urinate shows whether she is pregnant or not. Naturally, in all these cases, the bag material is transparent so that the required readings are immediately visible. Of course, various indicators should be combined with a gel-forming absorbent material and any enzyme present so that the functioning of all components is not disturbed by the presence of any other element.

 Figure 4 shows a modification of the front of the bag 10 to fit for use as a bag for collecting vomit during motion sickness. Such a modification can replace the existing bags currently used on airlines and ensure their quick removal. The design of the bag in FIG. 4 is basically the same as that shown in FIG. 1, except that the walls of the funnel 22 and 24 are connected at the seams that end at points 46 and 48, but the sides extend downward, forming sides 50 and 52. Each of the sides has a stiffening element at the edges 54 and 56, respectively, extending from the edge of the seam, and the excess material of one side is bent over the other side, thereby shifting the sides tightly together. As a result of this, a self-sealing one-way valve is formed, thereby preventing the ejection of vomit back from the bag during inspiration or compression of the material 42.

 Figure 7 shows the means for adapting the bag to use in a hospital with a catheter. This system includes a plug 58 having a tear-shaped cross section and a curved surface 60 for interacting with and sealing the curved portion of the opening 21 of the bag 10. The clamp 24 clamps the plug 58 and holds it in a sealed position. The plug includes a central opening 62 into which a catheter tube 64 is inserted.

 The bag is shown in the drawings as having a substantially rectangular or rectilinear or L-shaped. However, it will be obvious that it can be conical, have a rounded or sharp lower edge, or have other necessary shapes while maintaining adequate localization and removal functions.

 The advantage of the present invention compared to existing disposable urine bags and other liquid waste bags is obvious. The presence of a rapidly gel-forming material ensures complete collection and sequestration of liquid waste within a few seconds, so that a bag of collected liquid waste almost immediately becomes completely devoid of any leakage or spillage from it of any amount of waste. Thus, the bag can be immediately closed with a clip 34 or a zipper 43 and set aside for subsequent safe and convenient removal. In this condition, the bag is virtually immune to accidental spills. Thus, for example, a pilot or passenger of an aircraft can use the bag, close it and set it aside for a second, without worrying that subsequent air maneuvers can lead to splashing of the collected liquid waste in the cabin. Similarly, aerodrome workers can use the bag, immediately seal it and remove it, without worrying that subsequent bumps or falls can cause the contents to leak.
