Adhesive layer arrangements and methods for securing medical tubing

1 . An adhesive layer arrangement for securing catheters to patients comprising

a lower layer of hydrocolloid having first and second opposing ends, a bottom adherent surface extending between said first and second opposing ends for adhering to the body of a patient and a top surface extending between said first and second opposing ends;

a plow-fold release film covering said bottom adherent surface of said lower layer of hydrocolloid having a tab extending away from said bottom adherent surface; and

an upper layer of hydrocolloid having a bottom adherent surface for adhering to said top surface of said lower layer of hydrocolloid and to the catheter whereby, when said upper layer of hydrocolloid is pressed against said lower layer of hydrocolloid with the catheter disposed on said top surface of said lower layer of hydrocolloid, said upper layer of hydrocolloid deforms to securely grip the catheter and, in combination with said lower layer of hydrocolloid, secures the catheter to the patient's body preventing rotational, longitudinal and peeling movement of the catheter.

2 . An adhesive layer arrangement for securing catheters to patients as recited in claim 1 wherein said lower and upper layers of hydrocolloid have oval shapes and are separate layers.

3 . An adhesive layer arrangement for securing catheters to patients as recited in claim 2 wherein a polyurethane film is disposed on said top surface of said lower layer of hydrocolloid.

4 . An adhesive layer arrangement for securing catheters to patients as recited in claim 2 wherein said top surface of said lower layer of hydrocolloid is adherent to comingle with said upper layer of hydrocolloid.

5 . An adhesive layer arrangement for securing a catheter inserted into the body of a patient and for creating an occlusive seal at the insertion site at which the catheter enters the patient's body comprising

a first layer of hydrocolloid having a bottom adherent surface for adhering to the body of a patient and an opening for receiving the catheter;

a plow-fold release film covering said bottom adherent surface of said first layer of hydrocolloid having a tab extending away from said bottom adherent surface; and

a second layer of hydrocolloid extending from said first layer of hydrocolloid at a position adjacent said opening and having an outer adherent surface with a length sufficient to wrap around the catheter whereby said first and second layers of hydrocolloid can be pressed against the catheter and the body of the patient to deform and create an occlusive seal at the insertion site.

6 . An adhesive layer arrangement for securing a catheter inserted into the body of a patient and for creating an occlusive seal at the insertion site at which the catheter enters the patient's body as recited in claim 5 wherein said opening is a slot in said first layer of hydrocolloid.

7 . An adhesive layer arrangement for securing a catheter inserted into the body of a patient and for creating an occlusive seal at the insertion site at which the catheter enters the patient's body as recited in claim 6 wherein said first layer of hydrocolloid has an oval shape with opposing ends and said slot extends from one of said ends to terminate in a notch adapted to be aligned with the insertion site and to receive the catheter.

8 . An adhesive layer arrangement for securing a catheter inserted into the body of a patient and for creating an occlusive seal at the insertion site at which the catheter enters the patient's body as recited in claim 5 wherein said first and second layers of hydrocolloid are integrally formed.

9 . An adhesive layer arrangement for securing a catheter inserted into the body of a patient and for creating an occlusive seal at the insertion site at which the catheter enters the patient's body as recited in claim 5 and further comprising opposing plow-fold release films covering said outer adherent surface of said second layer of hydrocolloid having tabs whereby pulling said tabs exposes said outer adherent surface and wraps said second layer of hydrocolloid around the catheter.
