Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, pass through tool The utility model is further described in body embodiment.

A kind of self-retaining formula asoscope as shown in attached drawing 1~3, including annular fixed seat, is set to the annular fixed seat On arc fixed plate 1, arcuate movement plate 2, asoscope body and pawl ratchet mechanism；

The annular fixed seat includes straight bottom plate 3 and the arc top plate 4 with straight 3 integrally connected of bottom plate, the arc top plate 4 upper edges are circumferentially disposed there are three through-hole 5, and the arc fixed plate 1 is fixedly installed on the tail end of the arc top plate 4, the arc Movable plate 2 is set between the arc fixed plate 1 and the through-hole 5, and is sheathed on outside the arc top plate 4 and the arc top plate 4 are slidably connected, and one end of the arcuate movement plate 2 is set to by least one spring 6 on arc fixed plate 1, and the other end leads to Lock 7 is crossed to be set on the outer wall of the arc top plate 4；

The asoscope body includes the first arc asoscope piece 8 being fixedly installed on the straight bottom plate 3 and three pass through slip Handle 9 is set to the second arc asoscope piece 10 on the arc top plate 4, the first arc asoscope piece 8 and three the second arcs Asoscope piece 10 is enclosed detection hole 11, and described 9 one end of sliding handle is fixedly installed on the tail of the second arc asoscope piece 10 On end, the other end passes through corresponding through-hole 5 and is radially slided along the through-hole 5；

Be provided with ratchet 12 on the sliding handle 9, on the arcuate movement plate 2 with the 12 corresponding position of ratchet Pawl 13 is provided with, the pawl 13 and the cooperation of the ratchet 12 are construed as limiting the spine that the sliding handle 9 radially-inwardly slides Pawl gear mechanism.The detection hole 11 of the utility model is enclosed by four arc asoscope pieces, in use, the head end by asoscope body It stretches into nostril, four arc asoscope pieces slide in and out respectively, by nostril opening, detection hole 11 are made to become larger, is strutted by which Detection hole 11 into similar round, without slot, operation amplitude when will not be because of the appearance limitation operation of slot, the utility model nose Hole inner wall is close to, adjacent arc asoscope with four arc asoscope pieces (1 the first arc asoscope piece and 3 the second arc asoscope pieces) Gap is smaller between piece, and seamlessly transits, and will not nostril be overhanged dead angle, reduces the pain that asoscope is brought, reduces The pain of patient；The first arc asoscope piece 8 of the utility model is fixedly installed, and three the second arc asoscope pieces 10 pass through phase respectively Corresponding sliding handle 9 is set on arc top plate 4, makes three arc asoscope pieces outside by radially outward sliding sliding handle 9 It moves nostril opening, when four arc asoscope pieces are close to strut nostril with nostril respectively, asoscope is securable to nose It avoids falling from nostril on son, and the setting of 12 mechanism of ratchet ratchet, limiting sliding handle 9 radially-inwardly slides, so as to keep away Becoming smaller for caused by sliding handle 9 radially-inwardly slides detection hole 11 is exempted from, asoscope is slipped from nostril；The utility model is by ratchet The pawl 13 of 12 mechanism of ratchet is set on arcuate movement plate 2, and 2 sliding sleeve of arcuate movement plate is set on outside arc top plate 4, and arc is lived One end of movable plate 2 is connect with the arc fixed plate 1 on arc top plate 4 by spring 6, and the other end is connected with arc top plate 4 by lock 7 It connects, when limit slippage handle 9 is needed radially-inwardly to slide, spring 6 stretches, and arcuate movement plate 2 passes through lock 7 with arc top plate 4 It is fixed, carry out the radially-inwardly slip of limit slippage handle 9 so as to which pawl 13 be made to coordinate with ratchet 12, when operation finishes, need to tear open During lower asoscope, lock 7 is opened, under the action of the screen resilience of spring 6, arcuate movement plate 2 is slided to 1 direction of arc fixed plate, So as to which pawl 13 be made to be detached from ratchet 12, at this point, sliding handle 9 can be pushed radially-inwardly to slide, by three distracted arc noses Eyeglass inwardly closes up, and is then taken out from nostril, you can, the utility model realizes the self-retaining of asoscope, and not needing to external force makes it It keeps continuing softened state, and convenient and efficient toward nostril installation and removal.

Further, side there are two being respectively provided on 2 outer wall of arcuate movement plate with the 12 corresponding position of ratchet Plate 14 is provided with axis pin 15 between two side plates 14, and the pawl 13 is rotatably dispose on the axis pin 15, on the axis pin 15 Torsional spring 16 is arranged between the pawl 13 and corresponding side plate 14, one end of the torsional spring 16 is fixed with pawl 13 to be connected It connects, the other end is fixedly connected with corresponding side plate 14.Under the action of the screen resilience of torsional spring 16, can make pawl 13 by The power of 2 direction of arcuate movement plate rotation, makes pawl 13 be pushed against with arcuate movement plate 2, and limits the rotation of 13 negative direction of pawl, so as to Make the radially-inwardly slip of its limit slippage handle 9.

Further, 3 bottom of straight bottom plate, which is provided with made of Plastic implant, fixes bottom plate 17.The utility model On the one hand fixed bottom plate 17 can be made it be close to the upper lip between nose and lip, be played certain using Plastic implant Fixed function is supported, another convenience can also protect the skin of upper lip from damage.

The application method of the utility model：

When the utility model is installed, sliding handle 9 is radially-inwardly first slided into penetralia, by arcuate movement plate 2 and arc After top plate 4 is fixed by lock 7, the head end of asoscope body is inserted into nostril, later, radially outward slides sliding handle 9 by nose Hole struts；

When the utility model takes out from nostril, lock 7 is first opened, arcuate movement plate 2 is then under the action of 6 screen resilience of spring To fixed plate direction one end, so as to which pawl 13 be made to be detached from ratchet 12, at this point, sliding handle 9 can be slided radially-inwardly, make four Arc asoscope piece closes up, and after four arc asoscope pieces close up, asoscope loses supporting role, you can is taken out out of nostril.
