Abstract

An oral suction device includes a suction catheter having a suction portion at a first end, a shell surrounding the suction portion, and a suction tubing connector on a second end opposite the first end. The shell includes a hydrogel.

Claims

1. An oral suction device, comprising:

a suction catheter having a suction portion at a first end,

a shell surrounding the suction portion, and

a suction tubing connector, on a second end opposite the first end,

wherein the shell comprises a hydrogel,

the suction portion of the suction catheter comprises a plurality of holes,

the shell comprises a plurality of holes, and

the plurality of holes in the shell are configured to, in use, allow removal therethrough of fluid from an oral cavity of a patient, the oral suction device further comprising a sponge surrounding the suction portion, wherein the shell surrounds the sponge.

2. The oral suction device of claim 1, wherein the sponge is radiopaque.

3. The oral suction device of claim 1, wherein the hydrogel comprises a polymer, water and a salt.

4. The oral suction device of claim 3, wherein the salt is sodium chloride.

5. The oral suction device of claim 1, wherein the suction portion has a length of 2.5 to 30 cm.

6. The oral suction device of claim 1, wherein the oral suction device is sterile.

7. The oral suction device of claim 1, further comprising a retention connector attached to the suction catheter.

8. The oral suction device of claim 7, wherein the retention connector is a C-clip.

9. The oral suction device of claim 1, wherein the hydrogel comprises at least one member selected from the group consisting of polyacrylamide;

agar-agar;

polyvinyl pryrrolidone;

silicone hydrogels; and

polymers and copolymers of 2-hydroxyethylmethacrylate, glyceryl methacrylate, methyl methacrylate, N-vinyl pyrrolidone, N-vinyl-2-pyrrolidone, 2-methacryloyloxyethyl phosphorylcholine, ethoxyethyl methacrylate and methacrylic acid.

10. The oral suction device of claim 1, wherein the hydrogel comprises polyvinyl pyrrolidone, polyethylene glycol, agar-agar and water.

11. The oral suction device of claim 1, wherein the hydrogel is impregnated with an antibiotic.

12. The oral suction device of claim 11, wherein the antibiotic is at least one member selected from the group consisting of cephalosporines, fluoroquinolones, β

-lactams, carbapenems, glycopeptides and aminoglycosides.

13. The oral suction device of claim 1, wherein the shell has an expanded figure-8 shape.

14. The oral suction device of claim 1, further comprising an esophageal stethoscope and an electronic temperature probe.

15. The oral suction device of claim 14, further comprising a lead tube, wherein one or more leads located within the lead tube are in electrical communication with the electronic temperature probe.

16. The oral suction device of claim 15, wherein the one or more leads are connected to a lead adaptor.

17. The oral suction device of claim 1, wherein the shell has a length of 5 to 25 cm, a width at a widest point of 3 to 8 cm, a width at a narrowest point of 2 to 7 cm, and a height of 0.3 to 4 cm.

18. The oral suction device of claim 1, further comprising a vacuum lock relief tube inside the suction catheter, wherein the vacuum lock relief tube creates a gas pathway from atmosphere outside the suction catheter into the sponge or shell.

19. A method of removing fluids from a patient, comprising applying suction to the oral suction device of claim 1, wherein the oral suction device is within the oral cavity of the patient.

20. The oral suction device of claim 1, further comprising an esophageal stethoscope and an electronic temperature probe, wherein the esophageal stethoscope comprises a stethoscope tube having a listening end.

21. The oral suction device of claim 20, wherein the stethoscope tube is located within the suction catheter.

22. The oral suction device of claim 20, wherein a seal separates the listening end of the esophageal stethoscope from the suction portion.

23. The oral suction device of claim 1, wherein the hydrogel comprises a silicone hydrogel.

24. The oral suction device of claim 1, wherein the plurality of holes in the suction portion of the suction catheter is 6 to 100 holes, and the plurality of holes in the shell is 10 to 10,000 holes.

25. An oral suction device, comprising:

a suction catheter having a suction portion,

a sponge, surrounding the suction portion, wherein the sponge is radiopaque,

a shell comprising a hydrogel, surrounding the sponge and the suction portion,

a suction tubing connector on a first end of the suction catheter,

an electronic temperature probe on a second end of the suction catheter opposite the suction tubing connector,

an esophageal stethoscope comprising a stethoscope tube having a listening end, wherein the stethoscope tube enters the suction catheter near the suction tubing connector and is located within the suction catheter,

a seal, separating the listening end of the esophageal stethoscope from the suction portion,

a stethoscope connector on a first end of the stethoscope tube opposite the listening end, and

one or more leads in electrical communication with the electronic temperature probe.
