  • the wound evacuator includes a housing and a first port serving as a fluid inlet port communicating with the interior of the hous ing.
  • the first port is adapted to receive a tube designed to be placed internally within a patient adjacent to a wound in order to remove fluids from the vicinity of the wound.
  • a self-contained wound evacuator 10 is formed with a container 12 having opposed first and second side walls l6, l8 (hereinafter called front and back walls), opposed third and fourth side walls 20, 22 adjacent to the front and back walls l6, l8 and a bottom wall 24.
  • the container 12 is relatively rigid, which means that it will not deform substantially when it is subjected to the normal forces to which devices of this sort are expected to be exposed.
  • the container 12 is provided with at least one opening, such as port 26, extending through and communicating with the interior of the container 12.
  • the port 26 is adapted to receive flexible tubing 28 which is to be inserted into a patient adjacent to the wound being treated.
  • the tubing 28 is conventional wound tubing which is non-toxic, non-pyrogenic. inert, non-porous and non-degradable when used in its intended environ ment and which has a plurality of openings 29 at its dis tal end.
  • a second opening or port 30 be provided to serve as an outlet port to permit expulsion of air contained within the container 12 and to permit removal of fluid which is received within the container 12 during utilization of the wound evacuator 10.
  • a suitable closure or cap 32 is provided to permit selective opening and closing of the second port 30.
  • an air inflatable member is mounted within the container 12 and means for inflating and deflating the inflatable member are provided.
  • the inflatable member is a resilient bladder having an opening at one end 42 thereof.
  • the means for inflating the bladder 40 preferably is a manually operated pump, such as a handoperated bulbous resilient member having a resiliency at least only slightly greater than the resiliency of the bladder 40.
  • a resiiient member is a rubber bulb 44 having an air inlet 46 and an open neck 48.
  • the open end 42 of the bladder 40 is mounted in the neck 48 of the bulb 44 so that air expelled through the bulb neck 48 is forced to enter the bladder 40.
  • FIG. 2 4 While the bladder can be mounted directly on the walls of the bulb neck 48, the embodiment illustrated in FIG. 2 4 employs a plug 50 which is force-fitted within the neck 48, the plug 50 having an air passageway 52 axially therethrough.
  • the plug 50 is provided with an annular recess 54 to receive the open end 42 of the bladder, the open end of the bladder being trapped between the exterior of the plug 50 and the interior of the bulb neck 48 to fixedly hold the bladder in place.
  • the bulb 44 serves as the means to inflate the bladder 40 while the resiliency of the bladder serves as the means for deflating the bladder.
  • the bulb air inlet 46 is shown at the top of the bulb 44, it could be located at any other position.
  • locating the air inlet on the side has been found particularly convenient because it is easier to block the air inlet 46 with a finger or the heel of a hand.
  • an irregular surface such as a bead 51 is pro vided through which the inlet is formed.
  • the bead SI prevents the finger or hand from sealing the inlet during return of bulb to normal unsqueesed condition.
  • valve means are provided which are responsive to the difference in pressure between the bulb 44 and the bladder 40 so that when the pressure in the bulb exceeds the pressure in the bladder. the valve means permit free flow of air from the bulb to the bladder. However, when the pressure in the bladder 40 exceeds the pressure in the bulb 44. the valve means restrict the flow from the bladder to a predetermined minimal flow rate.
  • a slow leak check valve such as a flapper valve 56 having a small diameter bieed vent 58 therethrough, is mounted on the bladder side of plug 50.
  • a flapper valve 56 having a small diameter bieed vent 58 therethrough.
  • the bladder when the bladder is partially or totally inflated and the bulb 44 is returning from its squeezed or collapsed position to its normal or expanded position, the pressure within the bladder is higher than the pressure within the bulb and the flapper valve is forced against the plug 50 thereby obturating the air passageway 52 except for the vent S8 and preventing most of the air from leaving the bladder 40.
  • the small bleed vent 58 permits air to be expelled from the bladder 40 through the passageway 52.
  • the distal end of the wound tubing 28 is inserted in the patient before the proximal end is con' nected to the inlet port 26.
  • the wound tubing can be connected to the container 12 and closed by a conventional pinch clamp (not shown).
  • the closure 32 is removed from the outlet port 30 and the bladder 40 is inflated by alternately squeezing and releasing the bulb 44.
  • the user covers the air inlet 46 to prevent air from being expelled through the inlet, thereby requiring that all air expelled from the bulb 44 passes through the air passageway 52 into the bladder 40.
  • the bulb is released air enters the bulb through the inlet 46.
  • the flapper valve 56 prevents a substantial amount of air from flowing from the bladder 40 back into the bulb 44.
  • Continued pumping of the bulb inflates the bladder 40 which forces the air within the container 12 out through the outlet port 30 until such time as the inflated bladder substantially fills the container 22.
  • the proximal end of the wound tubing 28 is connected to the inlet port 26 (or the pinch clamp is opened) and the closure 32 is placed in the outlet port 30 thereby closing the port.
  • the bladder deflates the air in the bladder passes outwardly through the bleed vent 58, the air passageway 52 and the bulb air inlet 46. Deflation of the bladder 40 produces a negative pressure at the port 26 which causes fluids in the vicinity of the openings 29 at the distal end of the wound tubing 28 to pass through the tubing into the container 12.
  • the closure 32 is removed from the port 30 and the container is emptied, either by gravity feed (pouring the fluid out through the port) or by attaching the port 30 to the low pressure side of a pump and pumping the fluid out.
  • the body fluid can also be expressed from the container 12 by closing the pinch clamp and pumping the bulb 44.
  • the bladder inflates, it forces the body fluid out of the container and, when empty the bladder is fully inflated and the wound evacuator is ready for reuse. If only a single port 26 is used, the container is drained through the port 26.
  • the container 12 and the bladder 40 should have a combined actual or effective configuration so that the container does not physically interfere with or distort the inflation of the bladder 40 in at least one direction of inflation.
  • constant pressure and substantially constant pressure as used throughout this specification and in the claims are intended for use in a relative sense and do not imply absolute constant or unchanging pressure. For example a total pressure variation of up to about 30% throughout about 90% of the deflation range is acceptable.
  • a low profile container 12 (relatively narrow from front 16 to back 18) is preferred because it can be more comfortably and conveniently worn by a patient or attached to a support, such as a bed or chair.
  • a support such as a bed or chair.
  • the front and back walls l6, 18 are substantially flat and relatively closely spaced apart.
  • Substantially flat front and back walls are walls which either are truly flat or which have a radius of curvature much greater than the radius of the bladder 40 when the bladder contacts the front and back walls 16, 18.
  • a substantial vacuum is to be induced in the container 12
  • the bottom wall 24 of the container preferably should be flat.
  • the side walls 20, 22 are formed with a transverse outward curvature (from front wall to back wall) as can be seen in FIG. 2A.
  • the radius of transverse curvature is W /Z where W, is the distance between the front and back walls 16, 18. It also is desirable to avoid corners at the top and bottom of the side walls and, therefore, rounded upper and lower ends are formed or, alternatively, the side walls 20, 22 can be formed with a longitudinal curvature from top to bottom as can be seen in FIGS. 1 and 2.
  • the side walls 20, 22 can be made to effectively conform to the bladder shape by controlling the pressure within the container. More specifically, as the bladder 40 is inflated, the air inside the container 12 is expelled through the outlet port 30 until, after the bladder contacts the side walls 20, 22 and continues to inflate, it reaches a position within the container wherein the bladder is about to be forced into a shape which is different from what it would be if the side walls 20, 22 were nonexistent. At that time, the outlet port is occluded to prevent further expulsion of air from the container 12. Any further pressurization of the bladder 40 by pumping the bulb 44 results in a concommitant increase in pressure inside the container since the air cannot escape.
  • the outlet port 30 is occluded by the bladder 40 when it reaches its predetermined shape. This is effected by forming the outlet port 30 with an inwardly extending protuberance 31 which projects inwardly an amount calculated to bring it in contact with the bladder at the appropriate bladder inflation level.
  • the outlet port 30 and protuberance 31 can be formed as an integral part of the container 12 or it can be formed by a separate member mounted in an opening formed in the container 12. When this outlet port occluding concept is employed the shape of the container 12 is not critical.
  • the bladder thickness determines the vacuum level produced within the container.
  • a bladder thickness of 0.0lD has been found to produce a constant negative pressure in the above described container of approximately 30 inches of water (see FIG. 5).
  • the container perimeter/bladder diameter ratio is calculated to provide not greater than a seven fold increase in bladder diameter which has been found to be within a safe stress range for a latex bladder.
  • the bulb diameter (D should be approximately equal to the width of the container (D, W,).
  • FIG. 5 is a pressure vs. volume curve of a latex bladder having a three-fourth inch uninflated diameter, a 2 /2 inches free length and a 0.012 inch wall thickness which was inflated in a rigid container having dimensions substantially in accordance with the above dimension ratios.
  • the vacuum within the container remains between 31.3 inches of water at a bladder volume of about 4.5 times the uninflated bladder volume (4.5 V,) at which time the bladder first touched the relatively close container walls (eg l6, l8) and 29 inches of water.
  • the pressure remains at this level throughout the operating range of the wound evacuator and satisfactory results have been obtained at bladder inflations of over 30V,.
  • the total pressure variation over this range was only about 8% of the minimum pressure within the range (29 inches of water).
  • the pressure curve of FIG. 5 is considered to have a substantially constant pressure.
  • the container 12 can be formed of any suitable material such as a moldable plastic, for example, polyvinylchoride.
  • a moldable plastic for example, polyvinylchoride.
  • the shape of the container lends itself to being blow molded; however, it could be formed other ways, such as by injection molding.
  • At least a portion 59 of one of the flat side walls l6, 18 preferably is transparent and a calibrated graduated scale 60 is placed along the side thereof in order to enable volumetric measurement of the amount of fluid contained within the evacuator 10.
  • the container 12 also is provided with mounting tabs 61 to which a belt 62 or other support means is attached to facilitate hanging the wound evacuator 10 on a bed or chair or to enable the evacuator to be worn by an ambulatory patient.
  • a recess 63 in the interior surface of the container walls, particularly in the area leading to and adjacent to the outlet port 30.
  • a recess 63 assures the existence of a fluid flow passageway from the interior of the container 12 to the outlet port 30.
  • the interior surface of the container walls can be roughened, such as by injection molding the container, to accomplish the same results (FIG. 6).
  • Another means for preventing blockage of the outlet port is to provide a surface coating 64 on the interior surface of the container 12, (FIG. 7) or on the exterior surface of the bladder 40, which will lessen adherence of the bladder to the interior of the container.
  • a surface coating 64 on the interior surface of the container 12, (FIG. 7) or on the exterior surface of the bladder 40, which will lessen adherence of the bladder to the interior of the container.
  • chlorinating the surface of a latex bladder or coating the interior surface of a container with a conventional commercially available medical silicon successfully lessens adherence of the bladder to the container walls. Reduction of the adherence of the bladder 40 to the container walls also is of substantial assistance in maintaining the negative pressure substantially constant.
  • another form of resilient bulb such as bulb 66, illustrated in FIG. 8, may be used which eliminates the need for the operator to cover the air inlet in order to effectively inflate the bladder 40.
  • An automatically operating check valve such as a flapper valve 68, is located on the interior surface of the bulb 66 to normally cover the air inlet and is provided with a small diameter bleed vent 72.
  • the user squeezes the bulb 66 thereby increasing the pressure within the bulb. This increased pressure forces the flapper valve 68 against the air inlet 70 restricting the amount of air passing through the air inlet to be that small amount which can pass through the bleed vent 72.
  • the pressure differential across the flapper valve 74 between the bulb 66 and the bladder 40 causes the flapper valve 74 to open and permit the air to freely enter the bladder 40.
  • the resiliency of the bulb Upon release of the bulb 66, the resiliency of the bulb returns it to its original position increasing the volume within the bulb resulting in a reduced pressure within the bulb.
  • This produces a pressure differential across the flapper valve 68 causing the flapper valve to open and allowing atmospheric air to enter the bulb through the inlet 70 while closing the flapper valve 74 to prevent escape of air from the bladder.
  • the bladder 40 is inflated sufficiently, and the bulb returns to its normal position, air leaving the bladder 40 flows through the bleed vent 76 in the flapper valve 74, into the bulb 66 and through the bleed vent 72 in the flapper valve 68 and to the atmosphere.
  • a check valve such as a flapper valve 80
  • a flapper valve 80 can be mounted adjacent to the port 26 for closing the port 26 upon pressurization of the container, such as if the bulb 44 (or bulb 66) is accidently squeezed.
  • the check valve 80 does not interfere with the flow of fluid into the container 12 through the wound tubing 28.
  • the port 26 can be formed such that the bladder 40 occludes the port 26 when the bladder is inflated to its intended volume to further ensure against leakage through the port 26 to the patient.
  • a bulb can be used which has the same capacity as a fully inflated bladder. In other words, a single compression of the bulb would be sufficient to complete the inflation of the bladder. With a bulb of this size there is no requirement for an air inlet 46 and a closed system can be formed wherein air from the bulb fills the bladder and, when the bladder deflates, the air returns to the bulb for subsequent use. In such a closed system, a supple bulb, less resilient than the bladder, is used.
  • the fluid evacuator of this invention is completely self-contained,, portable and totally reliable. It is also easy and inexpensive to manufacture and, therefore, disposable. Of considerable significance are the safety features which prevent the fluid evacuator from being accidentally pressurized in a manner which will inject air or previously removed fluids back to the patient. Furthermore, the negative pressure formed at the inlet port which causes the forced removal of fluid from the patient is substantially constant thereby, (a) avoiding potential injury to the patient which could occur if the negative pressure is too high and (b) ensuring efficient operation of the evacuator throughout the entire operational range of the wound evacuator.
