## Abstract

An endoscope decontamination sheath includes a terminal section for seeing therethrough for an image and a sleeve section connected to the terminal section for receiving an endoscope to insert therein. The terminal section is of a tubular configuration. The terminal section has a front end to which a lens is mounted and a rear end in which an insertion groove is formed. The sleeve section is of an elongated tubular configuration having a front end fit into the insertion groove of the terminal section. In medical treatment of endoscopy or intubation, the endoscope is inserted into and sleeved with the sleeve section, and the endoscope sleeved with the decontamination sheath is inserted into an endotracheal tube. The matched arrangement between the lens and a lens of the endoscope helps prevent image deterioration and thus making images clearer. The decontamination sheath, after use, can be disposed of to prevent cross infection.

## Claims

### Claim 1

An endoscope decontamination sheath, comprising a terminal section adapted to see therethrough for an image; and a sleeve section connected to the terminal section and adapted to receive an endoscope to insert therein, wherein the terminal section has a front end to which a lens is mounted and a rear end that is formed with an insertion groove having a predetermined depth; the sleeve section is an elongated tubular body having a front end fit into and received in the insertion groove of the terminal section; and wherein after medical treatment with intubation, the used decontamination sheath is disposable of to prevent cross infection and also to prevent image deterioration to thereby make an image captured with the endoscope clearer.

### Claim 2 (depends on 1)

The endoscope decontamination sheath according to claim 1, wherein the terminal section comprises an outer tubular body and an inner tubular body connected to the outer tubular body, wherein the outer tubular body is of a tubular configuration in the form of a cylindrical cap having a top end that is formed with a through hole;
and the inner tubular body is of a tubular configuration in the form of a cylinder having an outer wall contacting and in tight engagement with an inner wall of the outer tubular body.

### Claim 3 (depends on 2)

The endoscope decontamination sheath according to claim 2, wherein the inner tubular body is provided with an upper stepped portion formed in an inside surface of an upper portion thereof to receive a lens to fit and position therein.

### Claim 4 (depends on 2)

The endoscope decontamination sheath according to claim 2, wherein the inner tubular body is provided with a lower stepped portion formed in an outside surface of a lower portion, such that the inner tubular body and the outer tubular body define the insertion groove therebetween.

### Claim 5 (depends on 2)

The endoscope decontamination sheath according to claim 2, wherein the outer tubular body and the inner tubular body are each formed of a stainless steel material.

### Claim 6 (depends on 1)

The endoscope decontamination sheath according to claim 1, wherein the sleeve section is formed of a plastic material.
