Description
Technical field
The utility model relates to field of medical device, and in particular to a kind of tracheal tube collar extension cladding system.
Background technique
Tracheotomy is to cut cervical trachea to be put into tracheal tube, and to release laryngeal dyspnea, breathing function loses
Dyspneic a kind of common surgical caused by normal or lower respiratory tract ischesis, and controlled for rescuing the important of patient vitals
Treatment means.
Usual holistic nursing care, conventional is covered at tracheae nozzle using one piece of wet gauze, prevent dust or
Foreign matter enters gas tube orifice.But this gauze piece is too big, influences the beauty of patient, and gauze piece is not fixed firmly, patient is mobile
When gauze piece be easy to fall.
Utility model content
The purpose of this utility model is to provide a kind of tracheal tube collar extension cladding systems, to solve current gauze covering gas
The problem of falling off from tracheal tube nozzle is easy when pipe-in-pipe nozzle.
In order to achieve the above objectives, the utility model adopts the following technical solution:
A kind of tracheal tube collar extension cladding system, including hollow closure plug, blocking plug includes plunger and conical plug, circle
The bigger diameter end of tapered plug is fixedly connected with plunger, slidably connects several anticreep drop pieces in conical plug, on the side wall of conical plug
The through-hole passed through for anticreep drop piece is offered, several anticreep drop pieces are distributed along the axial direction of conical plug, and several anticreep drop pieces
Length successively successively decrease along the axial direction of conical plug, be additionally provided in conical plug for driving anticreep drop piece to radially slide along conical plug
Driving mechanism, driving mechanism includes rotating bar and several are fixed on the actuator in rotating bar outer rim, and rotating bar is along conical plug
Axis extend, several actuators along rotating bar length direction be distributed, several actuators respectively with several anticreep drop pieces
End offsets, and the length of several actuators is incremented by successively along rotating bar length direction.
The working principle of this programme is:
Plunger is used to be in close contact with internal surface of sleeve pipe, plays the effect for blocking casing nozzle, conical plug due to one end is big,
The other end is small, can play the role of guiding to conical plug, due to plunger to the ponding of casing be by plunger outer rim with
Frictional force between internal surface of sleeve pipe is realized, and the usual deficiency of frictional force between the two will lead to plunger from casing nozzle
It falls off.It flushes when the free end of anticreep drop piece is initial with the outer rim of conical plug, after plunger is stretched out in anticreep drop piece free end, prevents
The part that falls off can also be pushed against with internal surface of sleeve pipe, further enhance the anti-dropout effect between plunger and casing.Anticreep drop piece exists
Sliding is realized by the movement of rotating bar and actuator in through-hole on casing, and the rotation of rotating bar is for driving rotating bar
Fixed actuator rotation in outer rim, since actuator and anticreep drop piece end offset, the rotation of actuator can give anti-dropout
The support force of part end one, so that anticreep drop piece free end is stretched out outside conical plug.The length of several anticreep drop pieces is along circular cone
The axial direction of plug is successively successively decreased, and is to adapt to successively decreasing for conical plug cross-sectional area.
Following technical effect can be reached using this programme:
1, by the frictional force between plunger and internal surface of sleeve pipe, it can make entirely to block to fill in be fixed on casing nozzle, be not easy
It falls off, external dust is not easily accessible in tracheal tube, and blocks plug and small volume, is not affected the appearance.
2, conical plug can play guiding role to plunger, and each anti-dropout bar in conical plug can and internal surface of sleeve pipe
It pushes against, further enhances the anti-dropout effect for blocking plug.
3, only rotating bar is needed to rotate, the free end of each anti-dropout bar just can be made to push against the inner wall of casing, operation letter
Folk prescription is just.
4, free end is flushed with conical plug outer rim when several anti-dropout bars are initial, does not influence conical plug push-in casing
It is interior.
Further, each anticreep drop piece includes two anti-dropout bars, and two anti-dropout bars are located at conical plug cross section
In same diametrical direction.The anticreep drop piece adopted the structure is simplest anticreep drop piece structure.
Further, the free end of anti-dropout bar is equipped with elastic rubber portion.Elastic rubber portion can increase anti-dropout bar and casing
Frictional force between inner wall, conical plug is more difficult to fall off out of casing, and elastic rubber portion can also play guarantor to internal surface of sleeve pipe
Shield effect.
Further, plunger is further fixed on limited block far from the end face of conical plug.When plunger is pushed into casing, limit
Position block can limit the depth of conical plug push-in.
Further, rotating bar one end is stretched out outside limited block, and the end of rotating bar is equipped with screw thread, and thread jacket has nut.
After rotating bar rotation, nut is turned, nut and limited block is pushed against, is able to achieve the locking of rotating bar rotational angle.
Further, rotation boom end is additionally provided with rotational handle.Rotational handle facilitates medical staff's rotary motion bar.
