Description

IMPLEMENT OF COUPLING OF MEDICAL CATHETER FIELD OF THE INVENTION The present invention relates to an apparatus and method for managing medical conduction tubes used to remove and / or introduce fluids or solids to / from the body of a patient, and more particularly to contain medical biological risks associated therewith in a space confined.

BACKGROUND OF THE INVENTION The conduction tubes such as catheters are used in a variety of medical procedures to inject or remove fluids, gases and / or solids from a patient's body. For example, thoracic catheters are used to drain fluids, solids and semi-solids from the mediastinum and chest cavities to remove pressure in the lungs. For injection purposes, percutaneous resident catheters and other similar devices are used to introduce blood and other intravenous fluids into the body of a patient. To use the aforementioned conduction tubes in the body cavities, it is necessary for the attending physician to make an incision in the patient's skin and the desired body cavity to insert the conduction tube. Typically, the conduction tube is then temporarily sutured directly to the surrounding tissue of the patient to anchor the tube toward the patient to prevent excessive movement or inadvertent removal of the conduction tube. This procedure is painful for the patient, time consuming and requires verification by the medical staff to ensure that the sutures and the conduction tube remain in place. During the removal of the inlet end of the conduit from the cavity of the patient's body, there is commonly a discharge of the medical biological hazard conduit. This discharge may include the fluids being injected or removed through the conduction tube, as well as blood and other medical biological hazards that are present in the patient's body. Exposure to these non-contained biohazard materials is potentially dangerous to health care personnel due to the possibility of acquiring Acquired Immune Deficiency Syndrome (AIDS), hepatitis, and other potentially infectious diseases carried in body fluids. Likewise, the disposal of biological risks is problematic for medical personnel who do not have the ability to contain biohazard materials in a transportable, contained space. After removal of the conduction tube, it is typically necessary for the attending physician or nurse to close the access wound in the patient's body with sutures, staples, or other similar devices. The wound should usually be cleaned, medicated and continuously checked to avoid infection and ensure proper healing. This procedure requires the change of couplings and other types of bandages on a time basis, which is expensive and does not facilitate verification of the wound without removing and completely replacing the couplings.

COMPENDIUM OF THE INVENTION Accordingly, it is a principal object of the present invention to provide a method and assembly for supporting and operating one or more body conduction tubes inserted in the body of a patient, which improves patient comfort, and is quickly applied to and Remove from the patient's body and be anchored to the patient's body without devices to close wounds. In this regard it is possible to anchor in the form of a support the body guide tube in the body of a patient without the need for sutures, staples, or other wound closure devices interconnected to surrounding tissue. It is another object of the present invention to provide an improved coupling assembly, which contains the medical biological risks associated with the use of body conduction tubes within a predetermined confined space, thus reducing the safety risks for health care personnel. In this context, the term "patient" refers to both humans and other mammals such as horses and dogs, and thus the described apparatus and method can be used in both medical and veterinary applications. To carry out one or more of the objects observed, as well as other advantages, a medical coupling assembly is provided, which includes an anchoring mechanism for supporting the body guide tube in the patient's body without the need for sutures The assembly is multifunctional and thus eliminates the need to have separate components to obtain the intended objectives of anchoring a conduit tube in a patient's body, containing the medical biological risks associated with it and applying a sterile coupling to the patient. the patient's access wound. The aforementioned assembly comprises a coupling pad selectively attachable to the skin of a patient adjacent to an access wound or incision. The access wound provides a penetration point for the conduction tube. A substantially rigid, straight retaining collar is removably interconnected to an upper surface of the coupling pad, and uses interconnection means for interconnection in the form of support to the conduit tube. The straight retaining collar may further have a plurality of longitudinal grooves oriented in the collar to allow the collar to be operatively crushed around the conduit tube. In this way, the coupling pad in combination with the straight retaining collar and the interconnecting means provide sufficient support for anchoring and stabilizing the conduction tube in the patient's body without the need for sutures, staples, or other means of tissue penetration. By way of example, in one embodiment, medical tape can be hermetically entangled around the retaining collar to temporarily interconnect the lead tube to the retaining collar. In an alternative, one or more o-shaped rings, or other similar support devices, may be used to stabilize the conduit tube within the straight retaining collar. The o-shaped ring is preferably placed near the inner surface of the straight collar and frictionally couples an outer surface of the driving tube to inhibit unwanted movement. Although the retaining collar generally extends in a direction substantially perpendicular to a flat surface of the coupling pad, in some circumstances, a less pronounced angle may be preferable. For example, when percutaneous resident catheters are used for injection purposes in a patient's artery or vein, less tension may be applied to the conduction tube and surrounding tissue using a retaining collar at a slight angle. In this way, the retaining collar can be placed at an angle of less than about 90 degrees, as measured from a plane - horizontal parallel to the coupling pad. Most preferably, the retaining collar may have an angle of between about 25 degrees and 75 degrees, as measured from a horizontal plane parallel to the coupling pad. In a further embodiment of the present invention, a biological risk control cuff is used that extends outward to substantially contain fluids such as blood or other medical biological hazards within a confined space to inhibit exposure with health care personnel. Preferably, the biohazard control sleeve is interconnected at a first end to the coupling pad near the access wound, while being placed in an extended form within the straight hold collar. The tube of The conduction is placed through both the confines of the biological risk control sleeve and the retaining collar, and is enclosed by the biological risk control sleeve. After the introduction or removal of fluids or solids to / from the patient's body through one or more conduction tubes, the inlet end of the conduction tube is removed from the patient's body. As the conduction tube is removed from the access wound, the biological risk control sleeve simultaneously extends outward and away from the patient's body with the conduit tube to substantially contain most of the medical biological risk discharge of both the delivery tube and the access wound in the patient's body. This containment significantly reduces the risk of medical biological risks being in direct contact with the doctors they care for, nurses and technicians, thus reducing the risk of exposure to infectious diseases carried in the blood, tissue and other matter of the body. The biohazard control sleeve can be constructed of a non-permeable, foldable, expandable material, such as polyvinyl chloride or polyolefin. This material, or other similar materials, are capable of being extended, for example, in a folded, folded, accordion-like form, many times its original length. This extension capability feature allows the biohazard control sleeve to be temporarily stored within the straight collar, still extended upwards at a distance of four to twenty times the original length of the straight collar. This ensures that most or all of the conduction tube that has been inserted into the patient's body is adequately contained by the control sleeve. In one embodiment, the biohazard control sleeve has a cord, fastener, or other means for holding both the upper end, lower end, and both ends of the biohazard control sleeve in a secured position around the conduit tube to assist to contain any medical biological risk. The biohazard control sleeve is then removed from the coupling pad by cutting the tube at a site near the coupling pad, or alternatively through the use of a perforated disconnect tab located on the coupling pad near the wound of access. To facilitate the extension of the biohazard control sleeve with the removal of the conduit tube, the straight collar may be temporarily and removably interconnected to an upper surface of the coupling pad. This can be achieved with a pressure sensitive adhesive, hook-and-loop type material, or other interconnecting means. In addition, to assist in the decoupling of the straight collar from the coupling pad, one or more pull tabs may be interconnected to the retaining collar support ring, which extends parallel to the upper surface of the coupling pad. In another embodiment of the present invention, a cover sheet is provided to promote healing of the access wound after removing the conduction tube from the patient's body. The cover sheet is preferably hingedly interconnected at an edge to an upper surface of the coupling pad. After removing the straight collar and biohazard control sleeve from the coupling pad, the access wound is exposed through a - opening in the coupling pad. The access wound is typically closed with sutures or staples and cleaned to prevent infection. The cover sheet can then be spread over the access wound and secured to the upper surface of the coupling pad with a pressure sensitive adhesive material, a hook-and-loop type material or other similar removable interconnecting means. The cover sheet may be temporarily disconnected or may be pulled from the access wound as required to verify wound healing access. In addition, sterile replacement cover sheets may be used as needed, and may include an impregnated medical ointment to promote healing. During the application, a method is achieved to use the coupling pad assembly by the physician first making an incision in the body of a patient to create one or more access wounds for the insertion of one or more conduction tubes. The inlet end of the conduction tube is then inserted through the access wound into a cavity, vein or artery of a patient's body, depending on the particular application. Thereafter, the coupling pad assembly is placed around the conduit tube through a slot, or alternatively by inserting the outlet end of the conduit tube through an opening in the coupling pad assembly and the retained retainer ring. . Once When properly positioned, the lower surface of the mating pad is secured to the patient's skin, preferably with an adhesive. The retaining collar is then secured to the conduction tube with the medical tape or preferably using attachment means, which are integral to the retaining collar, such as medical tape having a removable release liner, or other type of material that in Friction shape engages the conduction tube to inhibit movement. The conduction tube is then used for the intended purpose, that is, for the injection or removal of fluids, solids or semi-solids in or from the patient's body. After the removal of the conduction tube from the patient's body through the access wound, the biological risk control sleeve is simultaneously and progressively extended from the access opening in the patient's body. In this way, as the entrance end of the driving tube is removed from the access wound, any medical biological risk discharged either from the patient's access wound or from inside the driving tube, may be contained within of the biological risk control sleeve. In this way, the risk of exposure for health care personnel is significantly reduced. To facilitate the removal of the straight retention collar and the biohazard control sleeve of the coupling pad, a pull tab can be used to uncouple the retaining collar from the top surface of the coupling pad. The retaining collar is interconnected to a support ring, which is removably interconnected to the coupling pad with a pressure sensitive adhesive material or a hook-and-loop type material, such as Velero®. A biohazard control sleeve is suitably extended to contain the body guide tube, the biohazard control sleeve is cut close to the coupling pad with a knife or scissors. Alternatively, the biohazard control sleeve can be decoupled from the coupling pad with a perforated rupture surface. In a further embodiment of the aforementioned method, either one or both ends of the biological risk control cuff is closed with a cord, fastener, or other similar means to substantially capture the medical biological hazards within the biohazard control cuff. The cord or fastener may be permanently interconnected to the biohazard control sleeve, or be provided separately. This step also reduces the likelihood that medical personnel will be exposed to medical biological risks. After completion of the removal of the conduit tube, retaining collar, and biohazard control sleeve of the coupling pad, the access wound is left exposed for proper cleaning. The doctor then prepares the wound for proper healing and to avoid infection. closing the wound with sutures or staples. In a further embodiment, a sterile cover sheet may then be spread over the access wound to inhibit infection and promote healing.

DETAILED DESCRIPTION OF THE PREFERRED MODALITY Referring now to the drawings, Figure 1 illustrates the medical catheter coupling device placed over the chest cavity of a patient and used in conjunction with a body guide tube 14. Figure 2 shows an alternative embodiment of the present invention , wherein the catheter coupling device is used together with two body guide tubes 14. More particularly, the catheter coupling device comprises a coupling pad 2 temporarily interconnected to the skin of a patient and having a conduit tube 14 extending into the cavity of a patient's body. The conduit tube 14 is in the form of a support anchored to the patient's body through a straight holding collar 8, which is removably interconnected to an upper surface of the coupling pad 2. The straight holding collar 8 is temporarily interconnected to the conduit tube 14 to provide support to the conduit tube 14 with adhesive tape 26, one or more O-shaped rings 28, or through other similar interconnection means. The straight retaining collar 8 is placed on an access wound 32, through which the guide tube 14 is projected towards the body of the patient. A biohazard control sleeve 16, which can be extended, is placed within the retaining collar 8 and is used to contain the medical biological risks, such as blood, in a confined space during the removal of the body guide tube 14. of the patient. After the retaining collar 8 and the biohazard control sleeve 16 are disconnected from the upper surface 4 of the coupling pad 2, a cover sheet 20 can be used to removably cover the access wound 32 of the patient for promote healing. The coupling pad 2 is composed of a flexible polymeric or non-woven material, which provides a suitable barrier for contaminants, and which may have properties that lead to wound healing. The healing pad 2 generally has a rectangular or square shape, with a sufficient surface area to provide support for the straight retention collar and conduction tube 14. As seen in Figures 1-4, the attaching pad is positioned over a body cavity, such as the pleural chest cavity. or mediastinal and is positioned to support the conduction tube 14, which extends into the body cavity. The conduit tube 14 is generally projected through a coupling pad opening 34, which extends through the upper surface 4 of the coupling pad towards the lower surface 6 of the coupling pad. As seen in Figure 2, in some applications, two or more coupling pad openings 34 may be required when more than one conduit tube 14 is used. Alternatively, the coupling pad opening 34 may be replaced with a slot (not shown), which extends from one edge of the coupling pad to substantially the center of the coupling pad. This allows the coupling pad 2 to be positioned near and around the conduit tube 14 without requiring the end of the conduit tube 14 to be fed through the opening 34 during the placement of the coupling pad 2. The lower surface 6 of the coupling pad 2 is then temporarily attached to the patient's skin through an adhesive. The adhesive can be sprayed directly onto the skin of the patient, or very preferably it can be pre-applied to the lower surface 6 of the coupling pad 2 and protected from premature exposure to other surfaces with a release liner. In this application, a pressure sensitive adhesive is bonded to a polyolefin or polyvinyl substrate, which comprises the lower surface 6 of the coupling pad 2 and is covered with the release liner until it is desired to use. The release liner eliminates the need for spray adhesives or gums and, therefore, is more suitable for a medical application. In the immediate area surrounding the opening, preferably there is an adhesive-free region to help prevent the lower surface of the coupling pad 6 from adhering to the access wound 32. The upper surface 4 of the coupling pad 2 generally It is composed of a woven or nonwoven material, which facilitates the bonding of pressure sensitive adhesives. This is necessary in a manner to maintain the retaining collar support ring 10 firmly and still removably to the upper surface 4 of the coupling pad 2. For ease of use, in one embodiment, a release liner can be peeled off. the lower part of the retaining collar support ring 10 for exposing an adhesive, which is compressed against the upper surface 4 of the coupling pad 2. In an alternative embodiment, a hook-and-loop type material can be used. such as Velero® to removably connect the retaining collar support ring 10 to the upper surface 4 of the coupling pad 2. In this embodiment, an opposite section of the hook-and-loop type material must be interconnected to the surface 4 of the coupling pad near the opening 34 and opposite the lower surface 42 of the retaining collar support ring 10. To assist in disengaging the retaining collar 8 from the coupling pad 2 after removing the Conduit tube 14, a pull tab 12 of the retaining collar can be interconnected to the holding ring of the retaining collar 10 as seen in Figures 3-7. The retaining collar pull tab 12 is generally composed of a strip of plastic or cloth or fiber material, having a surface area large enough to allow clamping for removal of the retaining collar support ring. In another embodiment of the present invention, the upper surface 4 of the coupling pad 2 can have a control sleeve release ring 18, which is used to disconnect the biohazard control sleeve 16 from the coupling pad 2. The sleeve release ring 18 may be composed of a perforated strip, which is separated from the mating pad 2 by finger pressure, or a release strip (not shown), which is woven into the mating pad material to uncouple the mating pad. control sleeve release liner 18 when pulled. The control sleeve release liner 18 allows the biohazard control sleeve 16 to be disconnected from the coupling pad 2 to expose the access wound 32, thus eliminating the need for the biohazard control sleeve 16 to be Removed with a knife or scissors. To promote healing of the access wound 32, the upper surface of the coupling pad 2 can include a cover sheet 20. The cover sheet 20 can be loosely interconnected to the upper surface 4 of the collection pad 2, which prevents the cover sheet from being inadvertently disconnected from the coupling pad 2. Referring now to Figures 5-7, the cover sheet 20 of the coupling pad comprises an upper surface 22 and a lower surface 24, which it extends over the access wound 32. To facilitate healing of the access wound 32, the lower surface 24 of the cover sheet 20 can be impregnated with medicated ointment to inhibit infection or antibacterial. In addition, to prevent the cover sheet 20 from decoupling from the upper surface 4 of the coupling pad 2, a pressure sensitive adhesive with a release liner can be used to adhere to the upper surface 4 of the pad coupling 2. Alternatively, hook-and-loop type materials such as Velero® can be used to temporarily interconnect the lower surface 24 of the cover sheet to the upper surface 4 of the coupling pad. Although the cover sheet 20 is generally hingedly coupled to the upper surface 4 of the coupling pad 2, in another embodiment, the cover sheet 20 can be removably disconnected from the upper surface 4 of the coupling pad 2 to allow that the cover sheet 20 is replaced with a new sterile cover sheet coupling 20. As previously discussed, the conduit tube 14 is in the form of a support anchored to the upper surface 4 of the coupling pad 2 through the use of a straight retaining collar 8. The retaining collar is generally composed of a substantially rigid cardboard or plastic material, with an internal diameter large enough to receive the conduit tube 14. The straight retaining collar 8 has an upper end extending up and away from the coupling pad 2, and a lower end interconnected to the an The retaining collar support leg 10, which is removably interconnected to the upper surface 4 of the coupling pad. In one embodiment, the retaining collar 8 can have a plurality of longitudinal slots 30 extending in the same general upward direction as the retaining collar 8. These longitudinal slots 30 can be seen in Figures 1-4. The longitudinal grooves 30 allow the retaining collar 8 to be operatively crushed around the conduit tube 14 when it is applied at external pressure to the retaining collar 8. The external pressure is generally applied with an adhesive tape 26 (Figure 5), or alternatively through the use of a semi-rigid ring (not shown), which can be extended over the retaining collar to anchor the conduit tube 14 to the straight retaining collar 8 and coupling pad 2 as a support. embodiment of the present invention, as seen in Figure 5, a predetermined length of adhesive tape 26 is partially interconnected to the straight retaining collar 8 to allow the adhesive tape 26 to be conveniently wrapped around the retaining collar 8 to temporarily interconnect the retaining collar 8 to the conduit tube 14. In an alternative embodiment, the conduit tube 14 can be maintained as a support to the retaining collar 08 through the use of one or more O-shaped rings 28, as seen in the Figure 6. The O-shaped rings 28 are generally interconnected to the inner surface of the retaining collar 8 near or very close to the upper end of the retaining collar 8 and away from the support ring of the retaining collar 10. The rings 28 are shaped of O frictionally couple the outer surface of the conduit tube 14 and anchor the conduit tube 14 to the retaining collar as a support Straight n 8. The O-shaped rings 28 are typically composed of a rubber or polymeric material and may have chevron-like or other geometric patterns to provide support for the conduit tube 14. In addition, the O-shaped rings 28 serve for the purpose of substantially and circumferentially sealing the defined space between the inner surface of the straight retaining collar 8 and the outer surface of the conduit tube 14. In this way, most, if not all, of the medical biological risks that are present during the removal of the conduit tube 14 from the access wound 32 of the patient are substantially contained within the straight hold collar 8 and the biohazard control sleeve 16, and thus are not exposed to the medical care group . Referring now to Figure 7, in an alternative embodiment of the present invention, the straight retention collar 8 can be oriented relative to the surface of the skin at an acute angle, i.e., less than 90 degrees. This angle helps relieve excessive tension on the access wound 32 and surrounding tissue, and thus provides stability in certain applications where an artery, vein or body cavity is oriented more parallel to the surface of the skin. This orientation is particularly useful when the catheter coupling device is used to introduce fluid to the body of a patient, such as percutaneous resident catheters.

Preferably, the straight retention collar orientation angle 0 is between about 25 degrees and 75 degrees, and most preferably about 45 degrees.

Referring now to Figures 3-7, the present invention further utilizes a biohazard control sleeve 16 to contain discarded medical biological hazards either of the lead tube 14 or of the access wound 32 during the removal of the lead tube. 14 of the patient's body. More particularly, the biohazard control sleeve 16 can be comprised of an expandable folded material, which can be extended during the removal of the conduit tube 14 from the patient's body to contain any of the medical biological hazards within the body. biological risk control cuff 16. This containment helps to avoid exposure to the medical care group of various medical biological risks, such as blood and tissue. The biohazard control sleeve 16 generally has a cylindrical shape and has a lower end connected to the top of the coupling pad 2 near the access wound 32 of the patient. The upper end of the biohazard control sleeve 16 is placed about one third higher than the straight retainer collar 8, while the remainder of the biohazard control sleeve 16 is simulated stored within the internal diameter of the straight retention collar 8. To allow a significant extension, the biohazard control sleeve 16 is comprised of a folded accordion type material, which is substantially non-permeable to prevent medical biological hazards from saturating or otherwise leaking through the cuff biological risk control 16. For example, the biohazard control sleeve 16 may be composed of polyvinyl chloride or a polyolefin material, which may be folded or folded into an accordion-like shape. Preferably, the biohazard control sleeve 16 can be extended between about 4 to 20 times its original folded length. This allows the biohazard control sleeve 16 completely to wrap around the conduction tube 14, which has been placed within the body cavity of the patient. As seen in Figures 3-4, the biohazard control sleeve 16 is extended from the patient's body as the straight retention collar 8 is disengaged and pulled from the upper surface of the mating pad 2. A As the inlet end of the tube and conduit 14 is removed from the patient's body, the conduit tube 14 is contained within the biohazard control sleeve 16, thus substantially preventing the exposure of medical biological risks to the medical personnel. In a preferred embodiment of the invention, one or more cords 31 may be attached to the lower and / or upper ends of the biohazard control sleeve 16 to help contain any medical biological hazards therein. After removing the inlet end of the conduit tube 14 from the patient's body, the cord 36 is hermetically cinched for < , ' 24 contain substantially any of the medical biological hazards within the biohazard control cuff 16. The biohazard control cuff 16 can then be either cut with a knife or scissors below the cord and about 5 the surface upper 4 of the coupling pad 2, or the biohazard control sleeve release ring 18 can be used to disconnect the biohazard control sleeve 16 from the coupling pad 2 (Figure 4), exposing the wound of port 32. In an alternative embodiment of the present invention, shown in Figure 9, the straight retaining collar may further comprise an upper section of the retaining collar 42 removably interconnected to a lower section of the retaining collar 44. The upper section of the retaining collar 42 and the lower section 44 can be releasably interconnected with a release tab of the retaining collar 46. In this embodiment, the biohazard control sleeve 16 is interconnected at a lower end to the coupling pad 2 and at an opposite end to the upper section of retaining collar 42. The biohazard control sleeve 16 can be interconnected at the bottom of the upper retaining collar section 42 or at other operative sites in the upper section of the retaining collar 42. In this way, the Figure 9 only illustrates a particular modality and other effective designs can also be implemented to achieve the same purpose.

To remove the conduit tube 14 from the patient's body, the upper section of the retaining collar 42 is disconnected from the lower section of the retaining collar 44 through the retaining collar release tab 46. For example, the tongue releasing of retaining collar 46 can be interconnected to an interwoven web or cable in the retaining collar 8 to allow the upper section of retaining collar 42 to be disconnected from the lower section of retaining collar 44. After disconnection of the upper section of the retaining collar 42 and the lower section 44, the upper retaining collar section 42 is pulled from the lower retaining collar section 44, which remains removably interconnected to the upper surface of the coupling pad 4. As the upper section of retaining collar 42 is pulled from the patient's body, the The biohazard control sleeve 16 is extended upwards of the patient's body, while the simultaneously closes the conduit tube 14 and any of the medical biological risks discharged therein. After completing the removal of the conduit tube 14 above the lower retaining collar section 44, the biohazard control sleeve 16 can be closed with a cord, fastener or other device above the lower collar section of the collar. retention 44. The biohazard control sleeve 16 can then be cut with a knife or other sharp instrument to allow proper removal and disposal of the upper section of the retaining collar 42, the biohazard control sleeve 16 and the driving tube 14. The lower retaining collar section 44 can then be removed from the upper surface 4 of the coupling pad by pulling the retaining collar pull tab 12. Alternatively, instead of cutting the risk control sleeve biological 16 after the conduit tube 14 is removed above the lower section of collar 44, the pull tab 12 can be used to disconnect the lower section of the retaining collar 44 from the coupling pad 2, wherein the biohazard control sleeve 16 can be either cut close to the access wound or removed using the biohazard control sleeve release ring 18. During the practice, the medical catheter coupling device is used by the physician making an incision in the surface of the patient's skin and surrounding tissue to expose a cavity, artery or vein of the body. The inlet end of a conduit tube 14 is then inserted into the patient's body to facilitate the introduction and / or removal of liquids, solids and gases from the patient's body. The outlet end of the conduit tube 14 is then extended through an opening 34 in the coupling pad 2, which has a removably interconnected straight collar, positioned around the opening 34. The surface < \ 27 below 6 in the coupling pad 2 is then temporarily attached to the skin of the patient 40 through a spray adhesive or with adhesive pre-bonded to the lower surface 4 of the coupling pad 2. 5 The driving tube 14 then it is securely interconnected to the retaining collar 8 using an adhesive tape 26 which is wrapped tightly around the retaining collar 8. Alternatively, one or more O-shaped rings 28 can be used independently or together with the adhesive tape for securing the conduit tube 14 to the retaining collar 8. In this way, the conduit tube 14 is now securely anchored to the straight retaining collar 8 and coupling pad 2. After finishing the removal and / or introduction of fluids to Through the conduit tube 14, the retaining collar support ring 10 is disconnected from the upper surface of the coupling pad 2. This is achieved through the use of a pull tab 12. Alternatively, the upper section of Retaining collar 42 can be removed from the section lower retaining collar 44 pulling a retaining collar release tab 46. In either mode, as the physician pulls the retaining collar 8 away from the patient's body, the lead tube 14 is gradually removed from the body of the patient. patient through the access wound 32. As the conduit tube 14 is removed from the patient's body, the biohazard control sleeve 16 is progressively extended to close the conduit tube 14. In this way, the medical biological hazards are contained within the biohazard control cuff 16. Once the inlet end of the conduit tube 14 is pulled through the access wound 32, a cord 36 can be used to tighten and further contain any of biological medical hazards within the biological risk control cuff 16. Health care personnel can then either cut the cuff biological risk control 16 near the upper surface 4 of the coupling pad 2, or release the biohazard control sleeve 16 from the coupling pad 2 with the control sleeve release collar. In any case, the access wound 32 is now exposed for proper cleaning and / or wound closure through sutures, staples or other devices for closing wounds known in the art. To promote healing, a cover sheet 24 may be spread over the access wound 32 to prevent contaminants from coming in contact with the access wound 32. The cover sheet may be periodically replaced or rcted as necessary to verify the access wound healing 32.
