Description
Technical field
This utility model belongs to technical field of medical instruments, relates in particular to a kind of prebuckling endotracheal tube core positioner that is used for relative localization between prebuckling endotracheal tube core and the endotracheal tube.
Background technology
Endotracheal tube as the indispensable apparatus of Anesthesia Department of hospital, emergency department and larynx section is used more and more widely.Owing to be made of plastics on the endotracheal tube; Quality is softer relatively; Its rigidity is not enough, is head it off, and the doctor inserts in the endotracheal tube after adopting stainless steel silk to go up the moulding and sterilization of air flue characteristics by patient at present; Endotracheal tube can be kept and the same shape of stainless steel silk after moulding, so that the physiological bending of air flue is complementary on endotracheal tube and the human body.Because stainless steel silk does not have the special-purpose fixture that matches with endotracheal tube; Make stainless steel silk and endotracheal tube need the doctor to operate respectively, for this reason, need two doctor's co-operate in the tracheal intubation process at least with hands; If two doctors cooperate not tacit; The front end of stainless steel silk stretches out the endotracheal tube front end just has the possibility that injures the last air passage structure of patient, and perhaps the stainless steel silk front end is far away from the endotracheal tube front end, makes stainless steel silk can not play due moulding effect.Both of these case all should be avoided.
Summary of the invention
In order to overcome above-mentioned defective, this utility model provides a kind of can obtain effective localized prebuckling endotracheal tube core positioner in the optional position of the stainless steel silk of prebuckling endotracheal tube core.
This utility model solves the in-problem technical scheme of prior art: a kind of prebuckling endotracheal tube core positioner; It comprises the location matrix; The location matrix is provided with through hole; The medial wall of through hole one end is extended first positioning body and second positioning body respectively in opposite directions to the axial centre of through hole, is provided with locating hole between first positioning body and second positioning body.The location matrix is processed by elastomeric material, and the through hole that the location is provided with on the matrix and the outer peripheral face of endotracheal tube be close-fitting mutually, and the stainless steel silk of the locating hole that is provided with between first positioning body and second positioning body and prebuckling endotracheal tube core is close-fitting mutually; First positioning body and second positioning body are extended respectively to the axial centre of through hole by the medial wall of through hole one end in opposite directions, that is to say that first positioning body and second positioning body that form locating hole are splits.Like this when needing positioner on the stainless steel silk of prebuckling endotracheal tube core, to move; As long as promote external force that positioner moves when overcoming first positioning body or second positioning body and produce the needed power of deformation; First positioning body or second positioning body will produce deformation; The close-fitting condition between locating hole and the stainless steel silk that makes obtains destroying, and positioner just can move on the stainless steel silk of prebuckling endotracheal tube core by low weight loose ground; After arriving suitable location; Promote the external force disappearance that positioner moves; The deformation of first positioning body or second positioning body is restored under elastic effect; Close-fitting condition between locating hole and the stainless steel silk rebulids, and the endotracheal tube of close-fitting in through hole just can obtain the suitable location of shaping device, suitable fastening force.
The said first positioning body extending end is provided with the half slot that extends along the through hole axis direction, and the second positioning body extending end is provided with the arc groove that extends along the through hole axis direction, and half slot and arc groove form locating hole jointly.The width of said first positioning body on the through hole diametric(al) greater than with second positioning body.The said first positioning body inner face is positioned at the inboard of the second positioning body inner face.Like this can be so that elastic deformation only take place on second positioning body, first positioning body can play the guiding role.
Said locating hole and through hole coaxial arrangement.Like this can be so that the stainless steel silk on the prebuckling endotracheal tube core is positioned at the centre position of endotracheal tube.
Said first positioning body and the second positioning body outer face respectively with the end face of location matrix one end.Semicircular ring is extended laterally at its extending end in the said first positioning body outer face, and the internal diameter of semicircular ring is consistent with the internal diameter of locating hole, and the external diameter of semicircular ring equates with the width of first positioning body on the through hole diametric(al).Like this can be so that the delicate appearance of positioner, attractive in appearance.
The extended distance of said semicircular ring equals the first positioning body inner face and the second positioning body inner face in the axial distance of through hole.Make the inside and outside both ends of the surface of the positioning body of winning symmetrical with respect to second positioning body like this, the guide effect of first positioning body is optimized.
The relative two sides of said second positioning body are respectively equipped with supporter.Because for elastic deformation only occurs on second positioning body; The weakness that second positioning body is provided with respect to first positioning body; The two sides relative at second positioning body are provided with supporter, make second positioning body guarantee at first to take place to improve its mechanical performance under the situation of deformation.
The outer peripheral face of said location matrix one end is provided with the annular projection that is connected as a single entity.For the doctor moves the increase impetus with the hand propelled positioner.
The beneficial effect of this utility model is:
Because the location matrix is provided with first positioning body and second positioning body of split and forms locating hole jointly; With the stainless steel silk contact area on the prebuckling endotracheal tube core; First positioning body is greater than second positioning body; First positioning body play the guiding role, and second positioning body plays deformation effect, makes endotracheal tube can obtain effectively location in the stainless steel silk suitable location of prebuckling endotracheal tube core.
