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 for attaching the securement device to the body of the patient;

a fixed plate coupled to the pad, the fixed plate having a top comprising a planar portion;

an adjustable plate rotationally coupled to the fixed plate with an axis of rotation perpendicular to the planar portion; and

a first tab and a second tab coupled to the fixed plate, and a third tab and a fourth tab coupled to the adjustable plate, wherein the first and third tabs are configured to cooperatively secure a first portion of the medical implement when the adjustable plate rotates relative to the fixed plate such that the third tab is brought into proximity with the first tab, and wherein the second and fourth tabs are configured to cooperatively secure a second portion of the medical implement when the adjustable plate rotates relative to the fixed plate such that the fourth tab is brought into proximity with the second tab.

2. The device of claim 1, wherein the pad comprises a bottom surface, at least a portion of a bottom surface of the pad comprises an adhesive thereon for attaching the securement device to the body of the patient.

3. The device of claim 1, wherein a plurality of ratchet teeth are coupled to the adjustable plate, and a pawl coupled to the fixed plate, wherein the pawl is configured to engage the plurality of ratchet teeth to resist rotational movement of the adjustable plate with respect to the fixed plate.

4. The device of claim 1, wherein the adjustable plate comprises a slot, and the second tab extends from the fixed plate through the slot, the slot configured to permit the adjustable plate to rotate relative to the fixed plate.

5. The device of claim 1, wherein one of the first and third tabs and one of the second and fourth tabs are angle brackets, and the other of the first and third tabs and the other of the second and fourth tabs are flat tabs, wherein the first and third tabs are configured to cooperatively form a first passage and the second and fourth tabs are configured to cooperatively form a second passage when the third tab is brought into proximity with the first tab.

6. The device of claim 1, wherein an arm is coupled to the fixed plate and the pawl is fixed to the arm.

7. The device of claim 6, wherein a first end of the arm is pivotably coupled to the fixed plate about the axis of rotation of the adjustable plate.

8. The device of claim 7, wherein the pawl is coupled to a second end of the arm, opposite the first end.

9. The device of claim 1, wherein the first and third tabs are configured such that fourth tab is brought into proximity with the second tab when the adjustable plate is rotated counter-clockwise direction about the axis of rotation.

10. The device of claim 1, wherein the second and fourth tabs are configured such that the third tab is brought into proximity with the first tab when the adjustable plate is rotated counter-clockwise direction about the axis of rotation.

11. A method for securing a medical implement to a body of a patient, the method comprising:

adhering a pad having a fixed plate and an adjustable plate to the body of a patient, wherein the adjustable plate is rotatably coupled to the fixed plate about an axis of rotation perpendicular to a planar portion of a top surface of the fixed plate;

disposing a medical implement on a top surface of the device between (a) a first tab and a second tab coupled to the fixed plate, and (b) a third tab and a fourth tab coupled to the adjustable plate; and

rotating the adjustable plate relative to the fixed plate such that (i) the third tab is brought into proximity with the first tab to secure a first portion of the medical implement, and (ii) the fourth tab is brought into proximity with the second tab to secure a second portion of the medical implement.

12. The method of claim 11, wherein the first portion of the medical implement is secured within a first passage formed by the third and first tabs, and the second portion of the medical implement is secured within a second passage formed by the fourth and second tabs.

13. The method of claim 11, further comprising resisting rotational movement of the adjustable plate with respect to the fixed plate by engaging a pawl coupled to the fixed plate against a plurality of ratchet teeth coupled to the adjustable plate.

14. The method of claim 11, wherein the third tab is brought into proximity with the first tab, and the fourth tab is brought into proximity with the second tab, when the adjustable plate is rotated relative to the fixed plate in a counter-clockwise direction about the axis of rotation.

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

the medical implement;

a pad 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 comprising a planar portion;

an adjustable plate rotationally coupled to the fixed plate with an axis of rotation perpendicular to the planar portion; and

a first tab and a second tab coupled to the fixed plate, and a third tab and a fourth tab coupled to the adjustable plate, wherein the first and third tabs are configured to cooperatively secure a first portion of the medical implement when the adjustable plate rotates relative to the fixed plate such that the third tab is brought into proximity with the first tab, and wherein the second and fourth tabs are configured to cooperatively secure a second portion of the medical implement when the adjustable plate rotates relative to the fixed plate such that the fourth tab is brought into proximity with the second tab.

16. The system of claim 15, wherein the pad comprises a bottom surface, at least a portion of a bottom surface of the pad comprises an adhesive thereon for attaching the securement device to the body of the patient.

17. The system of claim 15, wherein the adjustable plate comprises a slot, and the second tab extends from the fixed plate through the slot, the slot configured to permit the adjustable plate to rotate relative to the fixed plate.

18. The system of claim 15, wherein a pawl, coupled to the fixed plate, is configured to engage the plurality of ratchet teeth, coupled to the adjustable plate, to resist rotational movement of the adjustable plate with respect to the fixed plate.

19. The system of claim 18, wherein an arm is coupled to the fixed plate and the pawl is fixed to the arm.

20. The system of claim 15, wherein the medical instrument is a catheter.
