Abstract

The utility model relates to a medical apparatus, particularly an apparatus for detecting nasal cavity. The utility model is composed of two tong-shaped pieces and an elastic connecting body; the upper and the lower binding part of one tong-shaped piece is provided with a convex block; a pair of convex blocks are arranged on the other tong-shaped piece; the two convex blocks are mutually embedded for positioning; the middle sections of the two tong-shaped pieces are respectively provided with a long hole which can penetrate through the connecting body; the upper parts are respectively provided with small round holes on both ends of a position stopping connecting body. The elastic connecting body is formed by that a spring steel wire is bent and is in the shape of an opening ladder. Both ends of the elastic connecting body respectively penetrate through the long hole in the middle part of the tong-shaped piece, and are clipped and stopped on the small round hole of upper part. The utility model only uses a bent spring as the connecting body, having the advantages of simple structure, no need of any tools in the process of assembly and low cost.

Description

Disposable asoscope

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of apparatus of checking that nasal cavity is used.

What hospital generally used in the last hundred years is the asoscope that metal material is made, and an asoscope is sterilized repeatedly and used for many years repeatedly.Because sterilization is difficult to completely, and patient is produced cross infection unavoidably.The all patent No. of the applicant provides a kind of asoscope simple in structure, with low cost, disposable for 93216250.9 asoscope patent, stopped cross infection, at the port, edge, especially entry personnel are checked that good effect is more arranged, and in light weightly be convenient to doctor's operation.But it is simple that the connection of its structure and on-off structure are still owed.

The purpose of this utility model is to improve on the basis of above-mentioned patented product, provides that a kind of structure is simpler, cost is cheaper, can disposable plastics asoscope.

This utility model is finished like this, form by two pincerlike sheets and nonrigid connector, it is characterized in that: there is a projection the upper and lower joint portion of a pincerlike sheet, on another pincerlike sheet a pair of projection is arranged, two projections embed mutually to locate, respectively there is a slotted hole that can pass connector in the stage casing of two pincerlike sheets, and the small garden hole at stop bit connector two ends is respectively arranged at top.Nonrigid connector is to be the opening trapezoidal shape by the spring steel wire bending.The nonrigid connector two ends are passed the intermediary slotted hole of pincerlike sheet separately and are limited to the small garden hole on top.This utility model only connects body with a bending spring, and structure is simpler.

This utility model compared with the prior art, its advantage is that its connector only uses a bending spring, structure is simpler, assembling is without any need for instrument, cost is lower.

Further specify accompanying drawing in conjunction with the embodiments

This utility model is by symmetric two pincerlike sheets 1,2 and connect body 3 with the trapezoid-shaped openings spring that spring steel wire bending forms and form, there is a projection 6 the upper and lower joint portion of pincerlike sheet 1, there is a pair of projection 7 the upper and lower joint portion of pincerlike sheet 2, respectively there is a slotted hole 5 projection 6 of two pincerlike sheets (1 and 2) and 7 lower end, and respectively there is a small garden hole 4 upper end.Projection 6 embeds to locate mutually with projection 7.Spring 3 respectively pass small garden hole 4 that slotted hole 5 is limited to top as connector 3 to form one group of expansible, closed asoscope.
