Abstract

The utility model relates to a nasoscope for visually observing a nasal cavity of a human body, comprising one left piece provided with a left head end and a right handle, one right piece provided with a right head end and a right handle and a pin shaft and a reset spring which are actively sheathed on the left and the right pieces. The utility model is characterized in that the head ends on the left and the right pieces are separated from the handles, and in addition, a separation position is respectively provided with a plug and a socket which can cause the head ends and the handles to be tabled and connected integrally. The utility model solves the problem of the existing rhinoscope that because the head ends and the handles are not removed and replaced, the head ends can not become disposable parts, and accordingly, cross infection among patients exists. A combined nasoscope provided by the utility model is also characterized in easy use and low fabrication cost, etc.

Description

The combination type asoscope

This utility model relates to a kind of asoscope that is used for visual human body nasal cavity.

Existing asoscope can see from Fig. 7 and Fig. 8 that wherein Fig. 7 is its front view, and Fig. 8 is the D-D cutaway view among Fig. 7.It contain 2, two of right sheets that a left sheet 1 with left head end 11 and left handle 12, one have right head end 21 and a right handles 22 at the chimeric connection in middle part and kink on bearing pin 3.If inwardly press handle, then left and right head end promptly opens to two outsides; Release handle, then spring 4 resets handle, and head end promptly closes up.Its shortcoming is: can not make disposable apparatus with the head end that patient's nasal cavity directly contacts and handle, its reason is that head end is an integral body with handle, and it normally adopts the rustless steel manufacturing, and cost is higher, price is more expensive, handles the back and reuses so asoscope can only be made routine disinfection.Therefore, existing asoscope is not precluded within the probability that cross infection is arranged between the patient.

The purpose of this utility model is to overcome the existing shortcoming of above-mentioned existing asoscope, and a kind of combination type asoscope that can avoid cross infection is provided, and makes it have low cost of manufacture and characteristics such as easy to use.

The combination type asoscope includes a left sheet with left head end and left handle, the right sheet with right head end and right handles, and the bearing pin of kink on left and right, be installed in the back-moving spring of handle inboard, characteristics of the present utility model be left head end on the left sheet with the right head end on left handle split, the right sheet with the right handles split, and in split place they have respectively can make the same left handle of left head end, right head end with right handles with chimeric plug that links into an integrated entity and the jack that is complementary with this plug.This plug can be a circular columns, or the transverse section is plane geometry shape, as the cylinder of triangle, square, rectangle etc., also can be dovetail; Jack can be the endoporus that is complementary with the shape of plug and size, or the dovetail groove that is complementary with dovetail.

To and contrast accompanying drawing by embodiment below, utility model will be further described below.Have in the accompanying drawing:

Fig. 1 is the front view of this utility model combination type asoscope;

Fig. 2 and Fig. 3 are respectively node I enlarged drawing and the A-A cutaway views among Fig. 1;

Fig. 4～Fig. 6 be head end in this utility model with the structure chart of another chimeric mode of handle, wherein Fig. 4 is that front view, Fig. 5 are that B-B cutaway view, Fig. 6 among Fig. 4 is the C-C cutaway view among Fig. 5.

Fig. 7 and Fig. 8 have represented the structure of existing asoscope, and wherein Fig. 7 is its front view, and Fig. 8 is the D-D cutaway view among Fig. 7.

Can see the structure of this utility model combination type asoscope from Fig. 1～3, it includes a left sheet 1 with left head end 11 and left handle 12, the right sheet 2 with right head end 21 and right handles 22, the structure of left and right head end and left and right handle is left-right symmetric, left and right with the tenon 13 that has on the left sheet with the chimeric connection of birch groove on the right sheet, and kink is on bearing pin 8, and spring 4 is equipped with in the inboard of handle.Left and right head end in this utility model asoscope is not an integral body with left and right handle, but is divided into two bodies, and split is in and has columniform plug 5 on the head end, has the jack that is complementary with this plug on handle.Head end is by the non-toxic plastic injection mo(u)lding, it as disposable part with the supporting use of stainless handle.
