## Abstract

A system for oral care of patients ventilated with an ETT tube 120 comprising: a deformable fluid blocking element 200 reversibly mountable around an ETT (for example, side-mountable thereon), the fluid blocking element having: a midsection channel 205 sized to fit snugly and reversibly around the ventilation tube 120 when the fluid blocking element is mounted thereto; and an outer surface configured, when the fluid blocking element is mounted, to fit snugly and reversibly into the back of the mouth of an adult human patient so as to span both lateral left-to-right tonsils and tongue-soft palate dimensions thereof, wherein the fluid blocking element 200 is reversibly inflatable to simultaneously press against the soft pallet and the tongue and/or the fluid blocking element 200 is collapsible and outwardly biased so that when placed in the back of the human mouth, the fluid blocking element expands so as to simultaneously press against the soft pallet and the tongue. Methods and kits are also disclosed herein.

## Claims

### Claim 1

A reversibly/side mountable system for oral care of patients ventilated with an endotracheal tube (ETT), the system comprising:
a deformable fluid blocking element reversibly mountable and side-mountable around the ETT, the fluid blocking element having:
(i) a midsection channel sized to fit snugly and reversibly around the ETT when the fluid blocking element is mounted thereto; and
(ii) an outer surface configured, when the fluid blocking element is mounted, to fit snugly and reversibly into the back of the mouth of an adult human patient so as to span both lateral left-to-right tonsils and tongue-soft palate dimensions thereof,
wherein the fluid blocking element is configured so that when mounted to the ETT, (A) the fluid blocking element is reversibly inflatable to simultaneously press against the soft palate and the tongue and/or (B) the fluid blocking element is collapsible and outwardly biased so that when placed in the back of the human mouth, the fluid blocking element expands so as to simultaneously press against the soft palate and the tongue.

### Claim at position 2

2-3. (canceled)

### Claim 4 (depends on 1)

The system of claim 1 wherein the deformable fluid blocking element is configured so that when mounted to the ETT, the fluid blocking element does not fully surround the ETT with a permanent ring.

### Claim 5 (depends on 4)

The system of claim 4 wherein the deformable fluid blocking element is configured so that when mounted to the ETT, the fluid blocking element fully surrounds the ETT with a reversibly openable ring.

### Claim at position 5

6-10. (canceled)

### Claim 11

A ventilation system comprising:
a. an endotracheal tube (ETT); and
b. a deformable fluid blocking element reversibly mounted around the ETT, the fluid blocking element having:
a midsection channel sized to fit snugly and reversibly around the ETT when the fluid blocking element is mounted thereto; and
an outer surface configured, when the fluid blocking element is mounted, to fit snugly and reversibly into the back of the mouth of an adult human patient so as to span both lateral left-to-right tonsils and tongue-soft palate dimensions thereof,
wherein (i) the fluid blocking element is reversibly inflatable to simultaneously press against the soft palate and the tongue and/or (ii) the fluid blocking element is collapsible and outwardly biased so that when placed in the back of the human mouth, the fluid blocking element expands so as to simultaneously press against the soft palate and the tongue.

### Claim 12 (depends on 11)

The system of claim 11 wherein the fluid blocking element is reversibly mounted around a proximal half of the ETT.

### Claim at position 8

13-24. (canceled)

### Claim 25

A system for oral care of patients ventilated with an endotracheal tube (ETT), the system comprising:
a. a deformable fluid blocking element reversibly mountable around an ETT; and
b. a suction tube attached to the fluid blocking element so that a distal end of the suction tube is situated and oriented to suck fluids from a proximal surface of the fluid blocking element,
the fluid blocking element having:
i. a midsection channel sized to fit snugly and reversibly around the ETT when the fluid blocking element is mounted thereto; and
ii. an outer surface configured, when the fluid blocking element is mounted, to fit snugly and reversibly into the back of the mouth of an adult human patient so as to span both lateral left-to-right tonsils and tongue-soft palate dimensions thereof,
wherein (A) the fluid blocking element is reversibly inflatable to simultaneously press against the soft palate and the tongue and/or (B) the fluid blocking element is collapsible and outwardly biased so that when placed in the back of the human mouth, the fluid blocking element expands so as to simultaneously press against the soft palate and the tongue.

### Claim at position 10

26-38. (canceled)
