     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    This invention relates to the enclosure system for treating of wounds on body parts which system includes disposable collection bags therewith. 
         [0004]    2. Prior Art 
         [0005]    Wound treatment and containment is a concept who&#39;s time has come. The increase in contamination and possible medical personnel injury is serious due to the increased size of the population having contagious diseases. The treatment process must include means for safe disposal of any patient tissue and any treatment material or treatment fluids. 
         [0006]    It is an object of the present invention to overcome the disadvantages of the prior art. 
         [0007]    It is a further object of the present invention to provide a wound or patient irrigation containment arrangement which maximizes the treatment capabilities of the medical personnel, and maximizes the safety considerations for those medical personnel. 
         [0008]    It is yet a still further object of the present invention to provide a wound treatment system for providing a containment arrangement which is less irritating to the patient, which treatment system may be stabilized and maintained about the patient for an extended period of time. 
         [0009]    It is yet a further object of the present invention to provide a wound containment system which is portable to permit such use to be performed in the field, in a home or any environment where such a need occurs. 
       BRIEF SUMMARY OF THE INVENTION 
       [0010]    The present invention comprises a wound containment arrangement for enclosing a wound on the surface of a patient. The wound enclosure arrangement, for example, may comprise an elongated flexible generally tubular plastic bag having a closed distal end and an open proximal end. 
         [0011]    The open proximal end in a first embodiment thereof, has a skin engaging cuff arranged therearound. The elongated enclosure bag itself, has one or more entry ports disposed thereon external thereto. Each respective entry port has an internally directed duck bill valve arranged thereadjacent. The entry port and the duck bill valve thus are in longitudinal alignment and are in fluid communication with one another. The entry port and duck bill valve permits a nozzle of a gun type control to extend therethrough. 
         [0012]    A gun type control mechanism permits the aiming and fluid control of a pressurized liquid or gas jetted therethrough from the nozzle onto the wound site for treatment within the enclosure bag. The enclosure bag in one preferred embodiment has at least one duck bill drain valve arranged on a lower portion thereof which duck bill valve is in fluid communication with a drain line which leads to a collection bag. The drain line and collection bag have a duck bill valve entry to permit the bag to receive but not leak any collection of debris from the patient being treated. 
         [0013]    A sanitizer means is preferably disposed in a dissolvable pouch which pouch is disposed within the collection bag. The sanitizer permits the dis-infection and decontamination of any fluid or debris collected from the wound of the patient being treated in the enclosure bag. 
         [0014]    The cuff at the proximal end of the enclosure bag in one embodiment, may have a soft, tissue sensitive, foraminous annular surface with a fluid conduit extending therearound. That fluid conduit in the cuff is in fluid communication with a suction pump arranged downstream thereof. The suction system permits a vacuum to be applied to the cuff so as to snugly and safely secure the proximal open end of the enclosure bag to the skin of the patient, while may also extract any extra contaminants or wound debris, but not irritably rubbing against a limb or surface of the patient being treated. 
         [0015]    In yet a further object of the present invention, an air vent with a pressurizable, temperature regulatable air, liquid or gaseous treatment fluid supply may be arranged in fluid communication through the enclosure bag. The air vent may be in communication with a pump to provide the air, liquid or treatment gases within the enclosure bag so as to space the enclosure bag a distance apart from the skin of the patient therewithin. The enclosure bag may have an air pressure relief valve, to control or limit fluid pressure and permit the pressurized air provided to the enclosure bag to gently escape, thus maintaining a constant or controllable pressure and/or temperature and/or medicament supply within the bag and against the patient&#39;s skin. 
         [0016]    A further embodiment of the present invention is contemplated by a flexible bubble-like enclosure arrangement which may be of generally hemispherical shape with an annular edge or lip extending therearound for attachment to the patient&#39;s skin. The bubble could also be of elongated or annular shape in other embodiments. The bubble is designed to be placed over a wound site of the patient. Such an enclosure bubble may have one or more input ports on an outer or external side of the pressurized enclosure bubble, and a corresponding duck bill inlet valve arranged in longitudinal alignment with the input port(s) on the inside surface of that enclosure bubble. The input port and the duck bill valve are in longitudinal alignment so as to permit the barrel of a pressurizable fluid supply nozzle to extend therethrough. The barrel and nozzle would be part of a gun type control mechanism which permits the aiming and the pressure, temperature or fluid mix control of a pressurized wound cleansing or medicament fluid(s) passing therethrough. The inlet valve, through which the elongated barrel and nozzle extends, itself may be elongated so as to sterilely enclose that elongated portion of the barrel, to eliminate the need for subsequent sterilization of that barrel in a further use thereof. The distal tip of the nozzle may be of stepped diameter so as to snuggly mate through an innermost opening of the inlet valve, thereby making only the nozzle sterilizable or replaceable during subsequent use thereof. The nozzle tip may be unscrewably removable from the barrel to facilitate that replacement or cleansing. 
         [0017]    The enclosure bubble in this embodiment may also include an arrangement of wires extending around the annular lip of the enclosure bubble, the wires connected to a controllable electrical source to provide electrical or rf stimulation in an encompassing annular or rectilinear pattern around the wound of the patient, so as to promote healing and stimulate healing and normal tissue growth. A drainage conduit may extend under or through the side of the wall of the enclosure bubble and into a collection bag as identified hereinabove. An air seepage vent may be arranged adjacent the input and duck bill valve arrangement or a spot nearby. Such seepage port will provide a controlled pressure and temperature atmosphere within the enclosure bubble arrangement on the patient. A conduit may be in communication with a controllable suction pump, in which the conduit is in fluid communication with a section cuff disposed in the annular lip or peripheral lip of the enclosure bubble. Such a suction would help hold the enclosure bubble to the patient with minimum adverse reaction to the patient, and also provide a secondary drain for treatment fluid removal. Further patient skin attachment systems may of course include adhesive or bandages of the like. 
         [0018]    In yet a further embodiment of the present invention comprises a plurality of enclosure bags successively disposed onto or about a patient&#39;s limb. In an operative example, such an inner and outer bag would be elongated so as to, for example fit over a patient&#39;s leg or foot having an opened end at its proximal end thereof. Such opened end would be fitted against a patient&#39;s leg and held thereagainst by a suction cuff as in the aforementioned embodiment. In the yet further embodiment of the present invention, it is contemplated that a plurality of wire loops may be arranged peripherally about the inner side or the outer bag, on the outer side of the inner bag, or disposed between the spaced apart enclosure bags. The loops pattern of wire are in electrical communication with a controllable electrical source so as to provide either heating, radio frequency (rf) treatment or those wires could be piezoelectric arrangement to generate wave induced energy for ultrasound treatment of the wound therewithin. 
         [0019]    It is still contemplated that an inner end of an inner duck bill valve would be in fluid communication with an outer port arranged in the outer bag. The nozzle of a treatment gun would extend through the outer port and the inner duck bill valve so as to permit controlled treatment fluid to be pressurizably disposed against the wound within the inner enclosure bag. Such a further embodiment would include a duck bill valve extending through a conduit which is in communication with the innermost enclosure bag. The duck bill valve would be in fluid communication with a conduit which extends to a collection bag. A duck bill valve would be arranged within the collection bag so as to prevent any backflow of contaminated fluid extending to return into the inner enclosure bag. 
         [0020]    It is further contemplated that a pressure source might direct fluid either gaseous matter or hardenable liquid between the inner bag and the outer enclosure bag. An air/fluid seepage patch might be arranged on the outer surface of the outer bag to permit controlled release and separation between the inner bag and the outer bag. A higher pressure fluid discharge nozzle may be arranged through both the outer and the inner bags so as to provide the fluid pressure to the patient&#39;s tissue within the inner bag. Such a high pressure source would controllably separate the inner bag from the patient&#39;s skin. 
         [0021]    The fluid source arranged in communication with the outer bag from the pressure source through the outer bag may be replaced by an injection component for splinting the patient&#39;s limb/leg which is enclosed within the inner bag. Such a form could press the inner bag against the patient&#39;s limb and be contained within the confines of the outer bag to provide a splint for a broken limb or the like. 
         [0022]    It is further contemplated by the present invention, that portions of the inner and/or the outer bag may be an electrically conductive plastic and/or thermally conductive or reflective or piezo stimulative for treating or heating tissue at the patient&#39;s wound site within the inner enclosure. 
         [0023]    Thus it has been shown a unique combination of treatment and containment for a wound which treatment and containment may be done by trained medical personnel and/or by emergency workers. Such containment system provides a sterile atmosphere and an arrangement for keeping the patient from becoming contaminated himself. 
         [0024]    The invention thus comprises a containment arrangement for safely and effectively treating a wound on a patient without contaminating attending personnel, comprising a patient receiving first enclosure having a patient contacting periphery, a pressurizable source in communication with the patient through a wall of the enclosure for enlarging the enclosure. A sealing means is arranged in the patient contacting periphery. A hand manipulable fluid discharge nozzle is extendably arranged through the enclosure for providing controllable treatment fluid to the wound on the patient within the enclosure. The sealing means may comprise a suction arrangement to hold the periphery of the first enclosure against the patient. The sealing means may also comprise a contaminated fluid removal system. The nozzle may extend through an inlet port and a one way valve. The containment system may include an electric treatment means arranged in the first enclosure. The treatment means may comprise an arrangement of electrically conductive members arranged around the first enclosure. The first enclosure has a peripheral lip, and wherein the conductive members are arranged in the lip of the first enclosure. The conductive members may be arranged on a wall portion of the first enclosure. The containment system may include a second enclosure arranged outwardly of the first enclosure. A separate pressurizable system may be arranged for the second enclosure. The separate pressurizable system for said second enclosure may include a fluid injecting arrangement and a pressure releasing arrangement. The separate pressurizable system for said second enclosure may also comprise a foam injection arrangement to provide a splint forming arrangement for the patient. The enclosure may comprise a metalized plastic to permit radio frequency treatment of the wound of the patient within the enclosure. An arrangement of conduction controlled electrical conduits may be arranged within the outer enclosure about the patient. The enclosure preferably has a contaminated fluid collection bag attached thereto, by a conduit therebetween, the collection bag containing a fluid sanitizer means therein. 
         [0025]    The inventive containment and treatment system also includes a cuff arranged therewith for sensing a patient&#39;s medical condition. The cuff preferably includes a tourniquet for preventing blood loss from the patient using the system. The containment system may include a patient monitoring and reporting arrangement therewith for monitoring and reporting vital signs of the patient being treated therewith. The monitoring and reporting arrangement may include a radio signal beacon generation arrangement for reporting the physical location of the patient being treated. The inlet port may comprise a sealed or fluid tight arrangement around a distal end of the barrel and nozzle arrangement. The nozzle is preferably removable from said barrel. 
         [0026]    The invention thus also comprises a containment arrangement for safely and effectively treating a wound on a patient without contaminating attending personnel, comprising: a patient-receiving first enclosure having a patient contacting periphery; a patient-sealing arrangement on the patient contacting periphery of the enclosure; a hand manipulable patient-treating fluid discharge gun extendable through the enclosure for providing controllable treatment fluid to the wound on the patient within the enclosure. The patient-sealing arrangement may comprise a suction arrangement to hold the periphery of the first enclosure against the patient. The patient-sealing arrangement may comprise an adhesive for securing the enclosure to the patient. The patient-sealing arrangement may comprise a contaminated-fluid removal system. The nozzle may extend through an inlet port and a one way valve. The fluid discharge gun may comprise a barrel and a distal nozzle thereon. The nozzle may be removable from the barrel to permit re-use of the discharge gun and its barrel, with a new uncontaminated nozzle on a new patient. The containment system may include a drainage conduit and a waste treatment fluid collection container for removing the treatment fluid from the enclosure. The drainage conduit may be gravity fed. The drainage conduit may be fed waste treatment fluid by a pressure from within the enclosure. The enclosure may be held at atmospheric pressure during the treatment of a patient therein. The enclosure may be held at above atmospheric pressure during the treatment of a patient therein. The enclosure may be held at below atmospheric pressure during the treatment of a patient therein. The enclosure may be held at a variable pressure during the treatment of a patient therein. The first enclosure may have a second patient-treating enclosure spaced therearound. 
         [0027]    The invention also includes a pulsatile lavage arrangement for the prevention of aerosol contamination so as to safely and effectively treat a wound on a patient without contaminating attending personnel and associated equipment, said arrangement comprising: a patient-receiving first enclosure having a patient contacting periphery; a patient-enclosure sealing mechanism arranged with respect to the patient contacting periphery of the enclosure; and a hand manipulable patient-treating fluid discharge gun extendable through the enclosure for providing controllable treatment fluid to the wound on the patient within the enclosure; and a waste treatment fluid drainage and collection system in one-way communication from the enclosure. The fluid drainage and collection system may be gravity fed. The fluid drainage and collection system may be fed by pressure. The fluid drainage and collection system may be removable from the enclosure and replaceable with a further fluid drainage and collection system. The fluid drainage and collection system may include a disinfectant within the collection system. 
         [0028]    The invention also includes a pulsatile lavage arrangement for the prevention of aerosol contamination so as to safely and effectively treat a wound on a patient without contaminating attending personnel and associated equipment, said arrangement comprising: a patient-receiving first enclosure having a patient contacting periphery; a hand manipulable patient-treating fluid discharge gun extendable through the enclosure for providing controllable treatment fluid to the wound on the patient within the enclosure; and a waste treatment fluid drainage and collection system in one-way discharge communication from the enclosure.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0034]    Referring now to the drawings in detail, and particularly to  FIG. 1 , there is shown the present invention which comprises a wound containment arrangement  10  for enclosing an entire patient, or a wound  12  on the surface of a patient “P”. The wound treating arrangement  10 , for example, may comprise an elongated flexible, generally tubular plastic bag  14  having a closed distal end  16  and an open proximal end  18  for keeping a patient/wound clean from both outside contamination and for preventing patient wound contamination/debris and or bacteria from spreading beyond the patient and or the patient&#39;s wound site. 
         [0035]    The open proximal end  18 , in a first embodiment thereof, has a skin engaging cuff  19  arranged therearound. The elongated enclosure bag  14  itself, has one or more entry ports  20  disposed externally thereto. Each respective entry port  20  has an internally directed duck bill valve  22  arranged thereadjacent. The entry port  20  and the duck bill valve  22  thus are in longitudinal alignment and are in fluid communication with one another. The entry port  20  and duck bill valve  22  permits a nozzle  24  of a fluid discharge gun type control mechanism  26  to extend therethrough. 
         [0036]    A gun type control mechanism  26  permits the aiming and fluid control of a pressurized liquid and/or gas jetted through the gun  26  from a temperature, pressure and medicament controlled source  28 , through the nozzle  24  and onto the wound site  12  for treatment within the enclosure bag  14 . The enclosure bag  14  in one preferred embodiment has at least one duck bill drain valve  22  arranged on a lower outer portion thereof, which duck bill valve  22  is in fluid communication with a gravity and/or pressure fed drain line  30  which leads to a collection bag  32 . The drain line  30  and collection bag  32  preferably have a duck bill valve  34  entry to permit the collection bag  32  to receive and contain but not leak any collection of debris from the patient “P” being treated. 
         [0037]    A sanitizer means  36  is preferably disposed in a dissolvable pouch  38  which pouch  38  is disposed within the collection bag  32 . The sanitizer means  36  is preferably dissolvable, and permits the dis-infection and decontamination of any bacteria, fluid or debris collected from the wound of the patient “P” being treated in the enclosure bag  14 . 
         [0038]    The cuff  19  at the proximal end  18  of the enclosure bag  14  in one embodiment, may have a soft, tissue sensitive, foraminous annular surface  40  with a fluid conduit  42  extending therearound. That fluid conduit  42  in the cuff  19  is in fluid communication with a pressure and/or suction pump  44  arranged downstream thereof. In use as a suction system, the pump  44  permits a vacuum to be applied to the foraminous inner annular surface  40  of the cuff  19  so as to snugly and safely secure the proximal open end  18  of the enclosure bag  14  to the skin of the patient “P”, while also may be arranged to extract any extra stray contaminants or wound debris, while not irritatably rubbing against a limb or surface of the patient “P” being treated. 
         [0039]    A further embodiment of the cuff  19  is represented in  FIG. 1  wherein the cuff  19  is a positively pressurizable conduit, having a separate conduit  21  therein to function as a tourniquet. The tourniquet conduit  21  may be controlled by a processor  23  to variably control the pump  44  for squeezing a patient&#39;s limb for a determined period of time, acting as the tourniquet or a blood pressure monitor for assistance to medical personnel. Such a system included miniaturized processor  23  may also have radio frequency capabilities to alert treating medical personnel as to the location, medical needs and/or stability or instability of the patient being treated. Such a portable system for patient treating, monitoring and locating is particularly advantageous in a military setting. 
         [0040]    In yet a further embodiment of the present invention, an air vent  50  with a pressurizable, temperature regulatable air, liquid or gaseous treatment fluid supply  52  may be arranged in fluid communication through the wall of the enclosure bag  14 , as shown in  FIG. 1 . The air vent  50  is in communication with a pump supply  52  to provide the air, liquid or treatment gases within the enclosure bag  14  so as to space the inside surface of the enclosure bag  14  a distance apart from the skin of the patient “P” therewithin. The enclosure bag  14  may have an air pressure relief valve  56 , to control and/or limit fluid pressure and permit the pressurized air provided to the enclosure bag  14  to gently escape, thus maintaining a constant or controllable pressure and/or temperature and/or medicament supply within the bag  14  and against the patient&#39;s skin. 
         [0041]    A further embodiment of the present invention is contemplated by a flexible fluid pressurizable, bubble-like enclosure arrangement  60  which may be of generally hemispherical shape with an annular edge or lip  62  extending therearound for attachment to the patient&#39;s skin, as shown in  FIG. 2 . The bubble enclosure arrangement  60  could also be of elongated or annular shape in other embodiments, (but not shown for clarity of the figures). The bubble enclosure  60  is designed to be placed over a wound site  12  of the patient “P”. Such an enclosure bubble  60  may have one or more input ports  64  on an outer or external side of the pressurized enclosure bubble  60 , and a corresponding one-way duck bill valve  66  or the like arranged in longitudinal alignment with the input port(s)  64  on the outside surface of that enclosure bubble  60 . The input port  64  and the duck bill valve  66  are in longitudinal alignment so as to permit the barrel  68  of a regulatable, manual hand or robot manipulable pressurizable fluid supply nozzle  70  to extend therethrough. The nozzle  70  would be the distal part of a gun-type control mechanism  72  which permits the aiming and the pressure, temperature and/or medicament fluid mixture control of a pressurized wound cleansing or medicament fluid  74  passing therethrough. 
         [0042]    The enclosure bubble  60  (or enclosure bag of the previous figures) in this embodiment may also include an arrangement of electrical conduits or wires  76  extending around the annular lip  62  of the enclosure bubble  60 , the wires  76  connected to a controllable electrical source  78  to provide a magnetic, electrical or rf stimulation treatment in an encompassing annular or rectilinear pattern around the wound  12  of the patient “P”, so as to promote temperature control, radiation, heating and/or stimulate healing and normal tissue growth. A gravity or a positive or negative pressure fed drainage conduit  78  may extend under or through the side of the wall of the enclosure bubble  60  and into a collection bag  80  through a one way duck bill valve  82 , similar to those as identified hereinabove. An air seepage vent  84  may be arranged adjacent the drainage conduit  78  or a spot nearby. Such seepage vent port  84  may help provide a controlled pressure and temperature atmosphere within the enclosure bubble arrangement  60  on the patient “P”. A fluid supply conduit  86  may be in communication with a controllable pressure and/or suction pump  88 , in which the conduit  86  is in fluid communication with a section cuff  90  disposed in the annular lip or peripheral lip  62  of the enclosure bubble  60 . Such a suction pump  88  would help hold the enclosure bubble  60  to the patient “P” with minimum adverse reaction to the patient, and may also provide a secondary pressure control and/or drain for motion induced patient tissue-stimulation and/or wound treatment fluid removal. Further patient skin attachment systems may of course include adhesive or bandages of the like. 
         [0043]    In yet a further embodiment of the present invention represented in  FIG. 3  comprises a first and a second enclosure bag arrangement  92  and  94  successively disposed onto or about a patient&#39;s limb. In an operative example, such an inner bag  92  and an outer bag  94  would be elongated so as to, for example fit over a patient&#39;s leg or foot having their opened ends  96  and  98  at its proximal end thereof. Such opened ends  96  and  98  would be fitted against a patient&#39;s leg and may be held thereagainst by a suction cuff  100  (or pressure cuff—for tourniquet application or patient sensing means) as in the aforementioned embodiments. 
         [0044]    In the yet further embodiment of the present invention, it is contemplated that a spiral or a plurality of conduits (fluid pressurized or electrically conductive) wire loops  102  may be arranged peripherally about the inner side or the outer bag  94 , and/or on the outer side of the inner bag  92 , or disposed between the spaced apart enclosure bags  92  and  94 . The loops or spiral pattern of conduits/wire  102  are in fluid and/or electrical communication with a controllable pressure/temperature and/or electrical source  104  so as to provide either cooling/heating, radio frequency (rf) treatment wherein those conduits/wires  102  could comprise a piezoelectric arrangement to induce rf wave energy for ultrasound treatment of the wound  106  therewithin, or for establishing a powered rf signal to a radio source for emission of a patient location beacon or treatment needs signal. 
         [0045]    It is still contemplated that an inner end of an inner duck bill valve  108  on the inner bag  92  would be in fluid communication through a connector conduit  93  with an outer port  110  arranged in the outer bag  94 . The nozzle  112  of a hand manipulable treatment gun  114  would extend through the outer port  110  and the inner duck bill valve  108  so as to permit controlled treatment fluid to be pressurizably disposed against the wound  106  within the inner enclosure bag  92 . 
         [0046]    A further embodiment would include a duck bill valve  116  extending from a conduit  118  which is in communication with the innermost enclosure bag  92 . The duck bill valve  116  would also be in pressurized and or gravity fed fluid-drainage communication with a conduit  120  which extends to a collection bag  122 . A one-way type duck bill valve  124  would be arranged within the collection bag  122  so as to prevent any backflow of contaminated fluid extending to return into the inner enclosure bag  92 . 
         [0047]    It is further represented in  FIG. 3 , that a pressure source  126  might direct fluid either gaseous matter or hardenable liquid through a channel  128  to the space  130  between the inner bag  92  and the outer enclosure bag  94 . An air/fluid seepage patch  132  might be arranged on the outer surface of the outer bag  94  to permit controlled release and separation between the inner bag  92  and the outer bag  94 . 
         [0048]    A controllable higher pressure fluid discharge nozzle  136  may be arranged through both the outer and the inner bags  92  and  94  so as to provide the fluid pressure to the patient&#39;s tissue within the inner bag  92 . Such a high pressure source would controllably separate the inner bag  92  from the patient&#39;s skin. 
         [0049]    The fluid source  126  arranged in communication with the outer bag  94  from the pressure source through the outer bag  94  may be replaced by an settable fluid or foam injection component for splinting the patient&#39;s limb/leg which is enclosed within the inner bag  92 . Such a settable, hardenable foam could press the inner bag  93  against the patient&#39;s limb and be contained within the confines of the outer bag  94  to provide a temporary or long term splint for a broken limb or the like. 
         [0050]    It is further contemplated by the present invention, that portions  140  and/or  142  of the inner and/or the outer bag  92  and  94  may be an electrically conductive plastic and/or thermally conductive or reflective or piezo stimulative for electrical signal generation through a proper circuit and or for treating or heating tissue at the patient&#39;s wound site within the inner enclosure  92 . 
         [0051]      FIG. 4  represents an embodiment of a barrel  200  and nozzle  202  which extends from the gun-type control mechanism  26 / 72 , shown in  FIGS. 1 and 2 . The barrel  200  and nozzle  202 , as part of the gun type control mechanism  26 / 72  permits the aiming and the pressure, temperature or fluid mix control of a pressurized wound cleansing or medicament fluid(s) passing therethrough. The inlet valve  204 , through which the elongated barrel  200  and nozzle  202  extend, itself may be elongated so as to sterilely enclose that elongated portion of the barrel  200 , to eliminate the need for subsequent sterilization of that barrel  200  in a further use thereof. The distal tip, for example, the nozzle  202 , may be of stepped or reduced diameter so as to snuggly mate through an innermost distal opening  206  of the inlet valve  204 , thereby making only the nozzle  202 , necessarily sterilizable or replaceable during subsequent use thereof. The nozzle tip  202  may be unscrewably removable from the barrel  200  to facilitate that replacement or cleansing. 
         [0052]    Thus it has been shown a unique combination of treatment and containment for a wound which treatment and containment may be done by trained medical personnel and/or by emergency workers. Such containment system provides a sterile atmosphere and an arrangement for keeping the patient from becoming contaminated himself.
