RELATED APPLICATIONS  
       [0001]     The present application claims the benefit of U.S. Provisional Patent Application No. 60/651,896, entitled “CHEMO T-SHIRT KIT,” filed Feb. 11, 2005, the disclosure of which is hereby incorporated herein by reference. 
     
    
     BACKGROUND OF THE INVENTION  
       [0002]     Patients undergoing medical procedures, whether in a hospital or in an outpatient setting, often find themselves in an uncomfortable environment. Many things, including the anxiety of having a medical procedure performed on their person, contribute to the discomfort experienced by the patients. In order to perform a procedure, a healthcare provider must have access to the site where the procedure is to be performed. This often results in patients having to take off all or some of their clothes, further increasing their level of anxiety. Without their clothes to protect them from the environment, the cool temperatures of the procedure room can cause patients to feel cold.  
         [0003]     One medical procedure that requires access to specific body sites is the administration of chemotherapy. In order to make venous access easier and to facilitate delivery of the chemotherapy to patients, doctors implant porta-caths in the patients. The porta-cath can be implanted subcutaneously, and accessed with a needle each time the patient needs chemotherapy. The actual location of the porta-cath depends upon the surgeon&#39;s placement. Thus, the location of the access site varies from patient to patient. Because the site is typically located somewhere on the chest, the patient&#39;s clothing usually covers the access site. The patient is required to pull his/her shirt/blouse up, or take it off altogether, leaving the patient exposed to the environment. This can be uncomfortable depending on the temperature of the room where the chemotherapy is administered. For women, this invasion of their modesty increases their discomfort.  
         [0004]     Some articles of apparel are designed to allow access to specific parts of the anatomy. There are bras designed to allow an infant access to the mother&#39;s breast for nursing. Underpants are designed to allow a person to use the restroom. Ski masks have openings for the eyes and the mouth. All of these items have one thing in common, namely they are designed and manufactured with a known fixed location for the opening that allows access to the body. In such manufactured articles, there is no ability to vary the location of the opening depending on the needs of the individual.  
       BRIEF SUMMARY OF THE INVENTION  
       [0005]     The present invention is directed to a method and apparatus for positioning and creating an opening in a person&#39;s clothing at a location that varies depending on the underlying location necessary to perform a medical procedure. The created opening allows access to a porta-cath without requiring the patient to remove his/her clothing.  
         [0006]     The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention.

     DETAILED DESCRIPTION  
       [0016]     In one embodiment, as shown in  FIG. 1 , patient  10  is wearing T-shirt  11 , which is to be adapted to allow access to a porta-cath (not shown, but located where dot  13  is to be placed) during the administration of chemotherapy. While the T-shirt is being worn by the patient, the porta-cath ( 401 ,  FIG. 4A ) is located underneath T-shirt  11  (or any other article of clothing covering the site of a medical procedure). Then, marker  12 , preferably a permanent marker, is used to place mark  13  on the T-shirt corresponding to the location of the porta-cath (or the site of the medical procedure) underneath the article of clothing. To locate the porta-cath underneath the T-shirt, the person placing the mark feels for the bump caused by the porta-cath. Mark  13  is placed directly on top of the bump identifying the porta-cath.  
         [0017]     In other embodiments, marker  12  can be anything that leaves an identifiable mark on the T-shirt. The marker can be a permanent marker, an ink pen, a pencil, a highlighter, or any other means for leaving an identifiable mark on the T-shirt. One could place a sticky marker or a pin on the location, or make a small hole to mark the area. Any method of making a mark that would allow the location of the porta-cath to be identified once the shirt is removed would suffice.  
         [0018]     As shown in  FIG. 2A , after the location of the porta-cath is marked on the T-shirt, it is removed. Then, circumference  20  of an appropriate sized opening is marked on the T-shirt. This circumference can be made by centering template  21 , designed with hole  23  in the center (as shown in  FIG. 2B ), allowing the template to be positioned over mark  13 . The circumference could be any size and shape appropriate for the medical procedure. In one embodiment, the template is circular with a diameter of 3.5 inches. Once the template is properly positioned, the patient (or any other person) can trace circumference  20  onto the T-shirt by using, for example, marker  12 .  
         [0019]      FIG. 3A  shows T-shirt  11  with circumference  20  traced onto it. Using a pair of scissors  30 , a hole is poked in the center of marked circumference  20 , through which the scissors can be used to cut an opening in T-shirt  11  corresponding to the shape of the template. A person skilled in the art would recognize that any instrument with an appropriate cutting surface could be used to create the opening.  
         [0020]      FIG. 3B  shows T-shirt  11  with created opening  42 .  
         [0021]      FIG. 4A  shows patient  10  wearing T-shirt  11  with opening  42  positioned over the porta-cath  401 .  
         [0022]      FIG. 4B  shows patient  10  wearing T-shirt  11  (under gown  43  which is optional) with opening  42  created for the administration of chemotherapy via tubing  41  extending from bag  40  into the porta-cath via opening  42 . The medical personnel use opening  42  to access the porta-cath during the administration of the chemotherapy. This procedure allows the patient a degree of comfort during an otherwise unpleasant experience.  
         [0023]     Another embodiment allows the creation of a non-permeable cover to place over an anesthetic applied to the skin over the porta-cath. To make access to the porta-cath less painful, patients place a local anesthetic on the skin over the porta-cath to anesthetize the skin for insertion of a needle to access the porta-cath. In order to create the cover, the patient needs a non-permeable material, such as a common household sandwich bag. The non-permeable material should be of sufficient size to allow the cover to be traced onto, and cut from, the material.  
         [0024]     To create the cover, a second template  51  as shown in  FIG. 5A , of smaller circumference than that of template  21 , is placed on a non-permeable material such as a sandwich bag  52  as shown in  FIG. 5B . The circumference of template  51  is marked on the non-permeable material using a marker, for example, marker  12 . Then, a cover of the non-permeable material is created by cutting around the traced circumference. This could also be accomplished by a person placing the template on the non-permeable material and cutting around the circumference of the template without first marking the material. In one embodiment, the template is circular and the diameter is 2.5 inches. After creating the finished cover, the patient applies the anesthetic either to one side of the cover, or to the skin covering the porta-cath. Then, the cover is placed over the anesthetic in contact with the skin that lies directly over the porta-cath. The cover can be secured to the skin with an adhesive such as surgical tape.  
         [0025]     In another embodiment, an opening is created, but the material is left in place with a small uncut portion of material acting like a hinge to create a flap. To create the hinged opening, the template is used to trace the circumference, but a portion of the material around the circumference is not marked, and is not cut by the scissors. Typically, the uncut portion would be at the top of the circumference. With the uncut portion at the top, the flap will hang down in the closed position when the person is upright, further protecting the modesty and comfort of the patient. Thus, the uncut portion creates a hinge to hold the cloth in place when not in use, but allows the flap of material to be moved out of the way during access.  
         [0026]     In other embodiments different sizes of templates could be used for different medical procedures. The only requirement being that the patient knows ahead of time where the medical procedure is going to be performed. For instance, if the patient needs to receive several injections to a particular joint, such as to a shoulder or to a knee joint, the physician could mark the appropriate location on the patient. If the mark cannot be seen through the clothing, then an artificial bump with adhesive on one side could be placed on the location identified by the physician. The patient could feel the artificial bump and mark the clothing in the appropriate location. Then, templates of appropriate sizes could be used to create an opening in the clothing to allow access to the area underneath. One skilled in the art would appreciate the adaptability of the present invention for a multiplicity of procedures necessitating access to different locations on the body.
