Description

Otolaryngoscope cover

Technical Field

The utility model belongs to the otolaryngoscope field, in particular to otolaryngoscope cover.

Background

An otolaryngoscopes is an optical device used in the department of otorhinolaryngology, and can carry out detailed examination on the nasal cavity and the throat. Specifically, an endoscope, a light source, and the like are built in one end of an endoscope tube inserted into a body cavity, and a diseased part in the body cavity is photographed and imaged, and an image thereof is displayed on a display screen, and a doctor observes the image and uses the image for diagnosis. Such as a large endoscope and a scope sheath, which is used in conjunction with the endoscope for examination, and is mainly used to prevent the endoscope from being reused and cross-infected. Then the front end of the lens is open, which can not completely isolate virus infection; and the product is difficult to be arranged on the mirror when in use and needs to be smeared with certain lubricating liquid. Also for example, lens sleeves for fitting soft nose-throat lenses are available on the market; the lens sleeve is matched with a soft nose-throat lens for examination and use, and is mainly used for preventing the soft nose-throat lens from being repeatedly used and preventing cross infection. When the product is used, the product is taken out from the package in the first step; the second step requires the injector to inject air from 1 to inflate the product; sleeving the software; fourthly, removing the outer hard casing from the position 2; and fifthly, air is pumped from the position 1, so that the soft wall of the lens sleeve is tightly attached to the soft lens. The above analysis shows that the installation process is complicated in order to attach the soft lens tightly.

CN207721789U discloses a hard tube endoscope keeps apart protective sheath pipe, and hard material still is difficult to break through and can't satisfy simultaneously with mirror pole and camera lens closely laminate and get into the demand that human body is quick, observe convenient.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the prior art otolaryngoscopes mainly comprise an elongated tube 101, a cone 102 for positioning at the proximal end of the tube, and an endoscope 103 at the distal end; the endoscope 103 can provide viewing fields of different perspectives, and the present embodiment provides a 0 ° endoscope, i.e., the endoscope 12 is positioned in a direction extending along the elongated tube; the periphery of the cone forms a step structure 131.

As shown in fig. 2, the otolaryngoscopic sleeve 1 is provided with a tube body 2 and a flaring section 3, the extension axial length of the tube body is matched with the tube 101 of the otolaryngoscopic mirror, such as an otoscope provided in the embodiment, so that the extension axial length of the tube body is limited appropriately; the flared section 3 and the tubular body 2 form a whole body for receiving an otorhinolaryngoscope, the tubular body 2 has a tubular thin wall 21 and a peripheral wall 22 extending proximally from the tubular thin wall 21, and with reference to fig. 3, the tubular thin wall is enclosed by a peripheral member 221 and a sealing top 222; in this way, the thin cylindrical wall 21 surrounds the distal endoscope 103, the peripheral wall 22 surrounds the elongated endoscope tube, and the flared section 3 surrounds the cone 102; so, flaring section 3 forms a whole cover with body 2 and outside the otolaryngoscopes, keeps apart otolaryngoscopes and human body, has avoided otolaryngoscopes to prevent the cross infection of virus at the used repeatedly process like this.

The inner wall of the flaring section 3 is provided with a limiting part in limiting fit with the step 131 of the conical body of the ear-nose laryngoscope, and the flaring section 3 is provided with a gripping part protruding outwards; in a preferred embodiment, the gripping member is at least one boss extending from the outside of the flared portion, as shown in fig. 3, the gripping member is two bosses 7, 8 symmetrically distributed outside the flared portion, and the two bosses 7, 8 are arranged on the upper side of the flared section; the design form and the setting position of boss can take multiple form, in this embodiment, refer to fig. 4, and the expansion opening 31 part peripheral area of flaring section forms the boss towards the outside expansion, and two boss departments are held between the fingers (are grabbed) to the hand, can realize blind operation, has effectively prevented the phenomenon of skidding, however, aforementioned mode of setting does not do the utility model discloses a restriction, it can let the operator take off or the mirror cover of loading with the form of grabbing, holding or holding between the fingers all can be used for implementing the utility model discloses a.

In addition, the structure of the limiting part comprises a bump, a convex point or a fastener and the like, in this embodiment, the limiting part is in the form of a limiting fastening point, as shown in fig. 4, the inner walls of the flared sections are pairwise arranged with limiting fastening points 5,6 symmetrically arranged on the inner walls of the flared sections, and the limiting fastening points are positioned on the step at the rear end of the otolaryngoscopic tube to realize the limiting fit of the otolaryngoscopic sleeve and the otolaryngoscopic lens; the phenomenon of falling off of the mirror sleeve is avoided.

It can be understood that the cylindrical thin wall 21 is made of transparent material, so that the condition of the inside of the ear, nose and throat can be observed by the endoscope, and as a better implementation mode, the whole endoscope sleeve provided by the utility model is made of transparent material; still further, in view of optical requirements, the cylindrical thin wall is of an ultra-thin design, and the cylindrical thin wall 21 has a wall thickness of not more than 0.25mm ± 0.1 mm; in another embodiment of the present invention, the otorhinolaryngological lens housing is made of transparent material MX 731.

In addition, the flared section 3 is injection moulded integrally with the tubular body 2, and, in cooperation with fig. 2, the flared section 2 extends from its wide-mouth opening 31 towards the elongated tubular body 2 to form a tapered cross-section.

In addition, according to the mirror pole length of different otolaryngoscopes, diameter and the endoscope angle change, the utility model provides a multiple transform can be done to disposable otolaryngoscopic cover's specification, and the purpose of transform aims at adapting to different otolaryngoscopes.
