Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a globular end optic fibre of area protection.
Background
When carrying out scope detection, because spherical optic fibre has wider field of vision effect, irradiation range is bigger, consequently adopts spherical optic fibre usually, but because spherical optic fibre's special construction, the spherical end lug connection who has great diameter promptly exposes optic fibre, consequently, is comparatively fragile in the junction of spherical end and exposed optic fibre, when carrying out scope inspection, especially bladder or gastroscopy, because the spherical end is comparatively fragile with the junction of exposed optic fibre, easily causes spherical end to drop because spherical end lacks the protection. Therefore, it is desirable to provide a simple and effective protection device to solve this problem.
SUMMERY OF THE UTILITY MODEL
Therefore, an object of the utility model is to provide a globular end optic fibre of area protection sets up the protection sleeve through the outside at globular end optic fibre, utilizes first protection sleeve along the axial direction back-and-forth movement of second protection sleeve, protects the junction of globular end and naked optic fibre, simple structure, convenient to use.
In order to achieve the above object, the utility model discloses a spherical end optical fiber with protection, which comprises a first protection sleeve, a second protection sleeve and a spherical end optical fiber; the first protective sleeve is movably sleeved outside the second protective sleeve, and the first protective sleeve can move back and forth along the axial direction of the second protective sleeve;
a spherical end optical fiber is arranged in the second protective sleeve, the spherical end optical fiber comprises a spherical end and a bare optical fiber, the spherical end is arranged at one end of the bare optical fiber, and the other end of the bare optical fiber is fixed in the second protective sleeve; the first protecting sleeve pipe moves backwards along the axial direction of the second protecting sleeve pipe, and the spherical end is exposed; when moving forward, the spherical end is hidden into the inner cavity of the first protective sleeve.
Further preferably, an identification bit is provided on the second protection sleeve, and the identification bit includes a start bit and a use bit.
Further preferably, a fixing device is arranged on the identification position and used for limiting the first protective sleeve.
Further preferably, the fixing device is a sticky device, and the sticking device is used for sticking and fixing the tail end of the first protective sleeve.
Further preferably, the fixing device is a detachable hoop, and the detachable hoop is used for clamping the tail end of the first protection sleeve.
Compared with the prior art, the spherical end optical fiber with the protection at least has the following advantages:
1. the protection sleeve is arranged outside the spherical end optical fiber, the first protection sleeve moves back and forth along the axial direction of the second protection sleeve, and the joint of the spherical end and the bare optical fiber is protected.
2. The identification position is arranged outside the second protective sleeve, and the relative position of the spherical end and the first protective sleeve is conveniently mastered through the identification position, so that the detection and the protection are facilitated.
Drawings
Fig. 1 is a schematic structural diagram of a protected ball-end optical fiber according to an embodiment of the present invention.
Fig. 2 is a schematic view of another usage state of the protected ball-end optical fiber according to the present invention.
In the figure:
1. a first protective sleeve; 2. a second protective sleeve; 3. a ball end; 4. bare optical fibers; 5. a start bit; 6. bits are used.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, an embodiment of the present invention provides a protected optical fiber with a spherical end 3, which includes a first protective sleeve 1, a second protective sleeve 2, and an optical fiber with a spherical end 3; the first protective sleeve 1 is movably sleeved outside the second protective sleeve 2, and the first protective sleeve 1 can move back and forth along the axial direction of the second protective sleeve 2;
a spherical end 3 optical fiber is arranged in the second protective sleeve, the spherical end 3 optical fiber comprises a spherical end 3 and a bare optical fiber 4, the spherical end 3 is arranged at one end of the bare optical fiber 4, and the other end of the bare optical fiber 4 is fixed in the second protective sleeve 2; the first protective sleeve 1 moves backwards along the axial direction of the second protective sleeve 2, and the spherical end 3 is exposed; moving forward, the bulbous end 3 is recessed into the internal cavity of the first protective sleeve.
Further preferably, the second protection casing 2 is provided with an identification bit, where the identification bit includes a start bit 5 and a use bit 6.
When using, set up first protective sheath 1 at beginning position 5, spherical end 3 introduces the inside cavity of first protective sheath 1 this moment, for example when carrying out cystoscope examination, pass through the urethra with first protective sheath 1, stretch into the bladder, because the narrow spherical end 3 of urethra under the protection of first protective sheath 1, can get into the bladder safely, stretch into back bladder after, with first protective sheath 1 along 2 axial directions of second protective sheath, slide backward, utilize spherical end 3 to detect or treat the bladder this moment, the tail end of first protective sheath 1 is located and uses position 6. After the use, the tail end of the first protection sleeve 1 is recovered to the start position 5 through the use position 6, at the moment, the first protection sleeve 1 is drawn out, the spherical end 3 safely exits under the protection of the first protection sleeve 1, and the detection is completed.
Further preferably, a fixing device is arranged on the identification position and used for limiting the first protective sleeve 1.
In one embodiment, the fixing device is an adhesive device, and the adhesive device is used for adhering and fixing the tail end of the first protective sleeve 1. When the trailing end of the first shield tube 1 is located at the use position 6 or the start position 5, the trailing end of the first shield tube 1 is fixed to the use position 6 or the start position 5 by an adhesive tape or a medical tape.
In another embodiment the securing means is a detachable collar for gripping the tail end of the first protective sleeve 1. When the tail end of the first protection casing 1 is located at the use position 6 or the start position 5, the tail end of the first protection casing 1 is clamped at the use position 6 or the start position 5 by using a detachable clamp or the like.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments.
