Abstract

A device for securing a medical implement, such as a catheter to a body of a patient. The device having an adhesive pad for securing the pad to the body of a patient. An adjustable plate is rotatable with respect to the fixed plate to secure a catheter. In some aspects, a pair of adjustable plates can be rotated with respect to the fixed plate. Tabs affixed to the fixed plate and the adjustable plate cooperate with each other to secure a catheter there between. The adjustable plate can be rotated so as to retain a catheter between the tabs. Complementary pawl and ratchet members are used to enable limited rotation of the plates with respect to one another and to fix the plates in a selected adjustment position.

Claims

1. A device for securing a medical implement to a body of a patient, the device comprising:

a pad having a bottom surface, at least a portion of the bottom surface having an adhesive thereon for attaching the securement device to the body of the patient;

a fixed plate coupled to the pad, the fixed plate having a top surface wherein a portion of the top surface is planar;

a first adjustable plate rotationally coupled to the fixed plate with an axis of rotation perpendicular to the planar portion of the top surface of the fixed plate;

at least one tab coupled to the fixed plate and the first adjustable plate, respectively, wherein the at least one tab is configured to cooperatively secure a first portion of the medical implement when the first adjustable plate rotates relative to the fixed plate such that the at least one tab coupled to the adjustable plate is brought into proximity with the at least one tab coupled to the fixed plate;

a first plurality of ratchet teeth coupled to the first adjustable plate; and

a first pawl coupled to the fixed plate, the first pawl configured to engage the first plurality of ratchet teeth to resist rotational movement of the first adjustable plate with respect to the fixed plate.

2. The securement device of claim 1, wherein a first tab is an angle bracket and a second tab is a flat tab, wherein the first and second tabs are configured to cooperatively form a passage when the first tab is brought into proximity with the second tab.

3. The securement device of claim 1, wherein the planar portion of the top surface of the fixed plate is at an angle in the range of 0-15 degrees relative to the bottom surface of the pad.

4. The securement device of claim 1, further comprising:

a second adjustable plate rotationally coupled to the fixed plate with an axis of rotation perpendicular to the top surface of the fixed plate;

at least one tab coupled to the second adjustable plate, wherein the at least one tab coupled to the second adjustable plate and the at least one tab coupled to the fixed plate are configured to cooperatively secure a second portion of the medical implement when the second adjustable plate rotates relative to the fixed plate such that the at least one tab coupled to the second adjustable plate is brought into proximity with the at least one tab coupled to the fixed plate;

a second plurality of ratchet teeth coupled to the second adjustable plate; and

a second pawl coupled to the fixed plate, the second pawl configured to engage the second plurality of ratchet teeth to resist rotational movement of the second adjustable plate with respect to the fixed plate.

5. The securement device of claim 4, wherein the fixed plate comprises at least two tabs.

6. The securement device of claim 4, wherein:

one of the at least one tabs coupled to the first adjustable plate is an angle bracket;

one of the at least one tabs coupled to the second adjustable plate is an angle bracket; and

one of the at least one tabs coupled to the fixed plate is a flat tab;

wherein the angle brackets are configured to cooperatively form a passage when the first and second adjustable plates are brought into proximity with the at least one tab coupled to the fixed plate.

7. The securement device of claim 4, wherein the first and second adjustable plates are rotationally coupled to the fixed plate by two pivot pins.

8. The securement device of claim 4, wherein the first and second adjustable plates are rotationally coupled to the fixed plate by a single pivot pin.

9. A method for securing a medical implement to the body of a patient using the device of claim 1, comprising the steps of:

adhering a pad having a fixed plate and an adjustable plate to the body of a patient;

disposing a medical implement on a top surface of the device; and

rotating the adjustable plate relative to the fixed plate such that the at least one tab coupled to the adjustable plate is brought into proximity with the at least one tab coupled to the fixed plate,

wherein a portion of the medical implement is retained within a passage formed by the at least one tab coupled to the adjustable plate and at least one tab coupled to the fixed plate.

10. A system for securing a medical implement to a body of a patient, the system comprising:

the medical implement;

a pad having a bottom surface, at least a portion of the bottom surface having an adhesive thereon for attaching the medical implement to the body of the patient;

a fixed plate fixedly coupled to the pad, the fixed plate having a top surface wherein a portion of the top surface is planar;

a first adjustable plate rotationally coupled to the fixed plate with an axis of rotation perpendicular to the planar portion of the top surface of the fixed plate;

at least one tab coupled to the fixed plate and the first adjustable plate, respectively, wherein the tabs are configured to cooperatively secure a first portion of the medical implement when the first adjustable plate rotates relative to the fixed plate such that the at least one tab coupled to the adjustable plate is brought into proximity with the at least one tab coupled to the fixed plate;

a first plurality of ratchet teeth coupled to the first adjustable plate; and

a first pawl coupled to the fixed plate, the first pawl configured to engage the first plurality of ratchet teeth to resist rotational movement of the first adjustable plate with respect to the fixed plate.

11. The system of claim 10, wherein the medical instrument is a catheter.
