Embodiment Construction

[0011] like figure 1 As shown, a sheath device for protecting the optical fiber probe head of a medical diagnostic instrument according to the present invention is composed of a tubular member 1. A closing portion is provided at the front end of the tubular member 1, and a through hole is arranged in the closing portion. hole 2, the axial direction of the through hole 2 coincides with the axial direction of the tubular member 1, wherein an elastic sleeve 3 is arranged in the tubular member 1, and the inner diameter of the elastic sleeve 3 smaller than the inner diameter of the tubular member 1 described above.

[0012] Further, the elastic sleeve 3 is made of medical latex tube.

[0013] Further, the elastic sleeve 3 is arranged at the end of the tubular member 1 .

[0014] Further, the inner side of the elastic sleeve 3 is provided with anti-slip protrusions or patterns.

[0015] Further, in the through hole 2, a lens 4 is fixedly arranged perpendicular to the axial direct...

Abstract

A protecting sleeve unit for protecting the optical-fiber detecting head used for medical diagnosis is composed of a tubular member with a closed front end having a coaxial through hole, and an elastic sleeve tube in said tubular member and with the antiskid lugs or pattern on its inner surface. When said tubular member sleeves on the optical-fiber detecting head, the elastic sleeve tube is deformed for firmly combining the tubular member with optical-fiber detecting head.

Description

Technical field: [0001] The invention relates to a measuring instrument, in particular to an optical fiber probe of a medical diagnostic instrument, in particular to a sheath for the optical fiber probe, in particular to a sheath device for protecting the optical fiber probe of a medical diagnostic instrument. Background technique: [0002] In the prior art, optical fiber probes of medical diagnostic instruments are commonly used clinically to detect human body lesions. During use, the optical fiber probes need to be in contact with human tissues. In order to prevent the virus carried by the human body from cross-infecting through the optical fiber detection head, an optical fiber sheath is installed on the optical fiber detection head. The head of the sleeve has a through hole which is smaller than the diameter of the sleeve and communicates with the inner cavity of the sleeve for passing light. The connection between the fiber optic probe head and the fiber sheath is just...
