Abstract

The utility model discloses a kind of trachea brackets for preventing displacement, including trachea bracket ontology, the trachea bracket ontology includes the inner membrance and outer membrane being fixed to each other, multiple ring skeletons are successively arranged between the inner membrance and outer membrane, along the length direction of trachea bracket ontology, the both ends of the trachea bracket ontology are respectively horn mouth.Known to from the above, the trachea bracket for preventing displacement of the utility model, pass through the effect of bell-mouth structure of air, the both ends of trachea bracket can be made to extending out, to make both ends and the inner surface of trachea of trachea bracket be formed and be interference fitted, trachea bracket is avoided to be displaced due to air-flow and movement in use.

Description

Prevent the trachea bracket of displacement

Technical field

The utility model relates to the technical fields of trachea bracket, and in particular to a kind of trachea bracket for preventing displacement.

Background technique

Tracheae caused by the lesions such as inflammatory granuloma, scar, tuberculosis, wound, tracheomalacia, amyloidosis, tumour and Bronchiostenosis, can cause obstructive pneumonia, atelectasis and expiratory dyspnea, the symptoms such as having difficulty in breathing, stridulate occur in patient, cough of choking Respiratory failure can occur for serious person and threat to life.Trachea bracket merging is one of the important means for the treatment of airway constriction, can be fast Speed releases expiratory dyspnea, improves clinical symptoms.Application in relation to airway stent was can be traced earliest to the nineties in 19th century.Nearly 20 Nian Lai, as the continuous development and Flexible bronchoscopy of material science are popularized in clinical, inner airway stent merging is just real It is able to be widely applied in clinic, provides chance for further treatment, while improving patients ' life quality.

But find in actual use, since user can cough or deeply breathe in daily life, at this moment It waits endotracheal throughput and flow velocity is very fast, the trachea bracket that will lead in tracheae is displaced, and after trachea bracket displacement, It will lead to that manufactured position of trachea is needed to lose support originally, and then lead to obstructive pneumonia, atelectasis and expiratory dyspnea.

Summary of the invention

The purpose of this utility model is that: a kind of trachea bracket for preventing displacement is overcome the deficiencies of the prior art and provide, is led to The effect of bell-mouth structure of air is crossed, the both ends of trachea bracket can be made to extending out, to make the both ends of trachea bracket and intratracheal Wall forms interference fit, and trachea bracket is avoided to be displaced due to air-flow and movement in use；Annular bone Spacing is equipped between the end of frame and horn mouth far from trachea bracket ontology, to make inner surface of trachea and bell-mouthed ring skeleton Between form gasket construction, avoid rigid ring skeleton from causing to damage to inner surface of trachea；Increase the lateral wall of trachea bracket With the contact point of inner surface of trachea, trachea bracket and cartilagines tracheales are blocked to be more advantageous to, and then can preferably avoid gas Pipe holder generates displacement due to air-flow and movement in use.

Technical solution adopted in the utility model is:

Prevent the trachea bracket of displacement, including trachea bracket ontology, the trachea bracket ontology include be fixed to each other it is interior Film and outer membrane are successively arranged multiple ring skeletons, institute between the inner membrance and outer membrane, along the length direction of trachea bracket ontology The both ends for stating trachea bracket ontology are respectively horn mouth.

It is the end of the ring skeleton and horn mouth far from trachea bracket ontology that the utility model, which is further improved scheme, Between be equipped with spacing.

The further improvement project of the utility model, which is that the ring skeleton is enclosed by the frame rod of " Z " type, to be made.

The further improvement project of the utility model is that the outer membrane of the trachea bracket ontology is located at the frame rod of " Z " type Bending place to being externally provided with protrusion.

The further improvement project of the utility model is that the bending place of the frame rod of " Z " type is circular ring structure, institute It states in the corresponding range for being located at protrusion of circular ring structure.

The utility model has the beneficial effects that:

The first, the trachea bracket for preventing displacement of the utility model can make tracheae by the effect of bell-mouth structure of air The both ends of bracket are interference fitted so that the both ends of trachea bracket and inner surface of trachea be made to be formed to extending out, trachea bracket are avoided to make With in the process air-flow and movement due to and be displaced.

The second, the trachea bracket for preventing displacement of the utility model, ring skeleton and horn mouth are far from trachea bracket ontology End between be equipped with spacing and to make to form gasket construction between inner surface of trachea and bell-mouthed ring skeleton avoid rigidity Ring skeleton inner surface of trachea is caused to damage.

Third, the utility model prevent displacement trachea bracket trachea bracket is increased by the effect of bulge-structure Lateral wall and inner surface of trachea contact point, trachea bracket and cartilagines tracheales are blocked to be more advantageous to, and then can be more preferable Ground avoids trachea bracket from generating displacement due to air-flow and movement in use.

Detailed description of the invention:

Fig. 1 is the schematic front view of the utility model structure.

Fig. 2 is the diagrammatic side-view cross-sectional enlarged diagram of the utility model structure.

Specific embodiment:

In conjunction with Fig. 1 and Fig. 2 it is found that the utility model includes trachea bracket ontology 1, the trachea bracket ontology 1 includes phase Mutually fixed inner membrance and outer membrane, are successively arranged multiple between the inner membrance and outer membrane, along the length direction of trachea bracket ontology 1 Ring skeleton 2, the both ends of the trachea bracket ontology 1 are respectively horn mouth 3；The ring skeleton 2 is with horn mouth 3 far from tracheae Spacing 4 is equipped between the end of rack body 1；The ring skeleton 2 is enclosed by the frame rod 7 of " Z " type to be made；The rami tracheales The outer membrane of frame ontology 1 is located at the bending place of the frame rod 7 of " Z " type to being externally provided with protrusion 6；The frame rod 7 of " Z " type it is curved It is circular ring structure 5 at folding, the circular ring structure 5 is corresponding to be located in the range of protrusion 6.
