the telescopic piece (3) is made of a material with certain elasticity.

Preferably, the hand-held part (4) is further included, one end of the hand-held part (4) is connected with one end of the first driving part (1), and the other end of the hand-held part is connected with one end of the second driving part (2).

Preferably, the telescopic member (3) is arc-shaped; the included angle a between the tangent line of the telescopic part (3) and the horizontal line is 0-45 degrees.

Preferably, the distance a between the first driving piece (1) and the second driving piece (2) and the connecting end of the handheld part (4) is smaller than the distance c between the first driving piece (1) and the telescopic piece (3) and the second driving piece (2).

Preferably, the first driving piece (1), the second driving piece (2) and the telescopic piece (3) are made of smooth stainless steel wires in the circumference.

Preferably, the first driving part (1), the second driving part (2) and the telescopic part (3) are stainless steel wires with the wire diameter of 0-3 mm.

Preferably, the first driving piece (1), the second driving piece (2) and the telescopic piece (3) are stainless steel wires with the wire diameter of 0.8 mm.

3. Advantageous effects

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides a mouth nose interchanger, through pressing first driving piece and second driving piece, drives the extensible member and draws in and open for the contractive member can be stretched to the throat from the oral cavity, and the tip that will follow the exchange tube that wears out in the nasal cavity is located between extensible member and first driving piece and the second driving piece, through the interchanger, will exchange the tube and pull out from the oral cavity.

A mouth nose interchanger, the line footpath is 0.8 mm's stainless steel wire, and the surface is smooth, and is little to the stimulation of throat, and is little with the area of contact of throat, is rich in elasticity moreover, when opening, can with the laminating of throat inner wall for the tip of exchange tube falls into the interchanger, has improved work efficiency effectively, has prevented many patients' of repetitious operations influence.

The invention can effectively carry out the oral-nasal exchange and can well reduce the damage of the oral cavity, the throat and the throat.

Detailed Description

As shown in fig. 1-6, a mouth-nose exchanger comprises a first driving member 1, a second driving member 2 and a telescopic member 3. Wherein, the one end and the first driving piece 1 one end of extensible member 3 are connected, and the other end and the second driving piece 2 of extensible member 3. Extensible member 3 is the arc for the both ends of extensible member are located the homonymy, and first driving piece 1 and second driving piece 2 are through being connected the back with

extensible member

3, and 1 box second driving piece 2 of first driving piece are located same one side of extensible member 3, and moreover, extensible member 3 will have certain elastic material and make. Through applying external force to first driving piece 1 and second driving piece 2, make first driving piece 1 and second driving piece 2 draw close each other, make the both ends of extensible member 3 be close to each other under the drive of first driving piece 1 and second driving piece 2, the arc portion transverse distance of extensible member 3 reduces, conveniently pass through the oral cavity, get into the throat position, remove the external force of first driving piece 1 and second driving piece 2, make 3 external forces of extensible member cancel the back, resume initial state, the lateral wall and the laminating of throat inner wall of extensible member 3, make 5 tip of exchange tube of wearing out in the follow nasal cavity fall into the mouth nose interchanger, through pulling mouth nose interchanger, pull out exchange tube 5 from the oral cavity.
