Abstract
The invention relates to a medical flexible pipe, in particular to an anti-occlusion trachea cannula. The anti-occlusion trachea cannula comprises a flexible pipe body, wherein a memory alloy supporting frame is embedded into the pipe wall of the flexible pipe body; the memory alloy supporting frame is woven by titanium nickel memory alloy threads with large diameters; the diameters of the titanium nickel memory alloy threads are between 0.5mm and 2.5 mm. According to the anti-occlusion trachea cannula, the memory alloy supporting frame is embedded into the pipe wall of the flexible pipe body, the strength of the pipe body is high, the supporting force of the pipe is high, and pipe body blockage caused by occlusion of teeth of a patient is effectively prevented.
Description
Technical field
The present invention relates to flexible pipe for medical purpose, particularly anti-interlock tracheal intubation.
Background technology
At present, in patient with severe symptoms's treatment, direct oral cavity inserts endotracheal tube, is the most frequently used artificial airway's the mode of setting up, for example, at home during known clinical cardio-pulmonary resuscitation, one of the most frequently used emergency measures, is about to air tube direct oral cavity and inserts in patient's trachea, and patient is strengthened to assisted respiartion.Because adapt to the flexibility of air flue in human body, body in above-mentioned insertion patient body selects the good material of suppleness to make conventionally, yet in actual use, after body is inserted in patient body, because the phenomenon that tooth is tightly stung easily appears in patient in treatment, use the poor body of rigidity easily by patient's dental articulation, cause body inaccessible, cause to breathe and interrupt or liquid such as cannot be input in patient body at the problem.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art, a kind of anti-interlock tracheal intubation is provided.
For achieving the above object, the invention provides following technical scheme:
Anti-interlock tracheal intubation, comprises hose body, and the tube wall of described hose body is embedded with memory alloy stent, and described memory alloy stent is formed by the thicker ti-ni shape memory alloy line braiding of diameter, and the diameter of described ti-ni shape memory alloy line is 0.5mm～2.5 mm.
In above-mentioned anti-interlock tracheal intubation, described memory alloy stent is helical tubular structure.
In above-mentioned anti-interlock tracheal intubation, described memory alloy stent is netted lattice circular tube structure.
The present invention is embedded with memory alloy stent at the tube wall of hose body, described memory alloy stent adopts the ti-ni shape memory alloy line that diameter is thicker to form, intensity and the support force of body are enhanced, in use, first the hose body that contains memory alloy stent is inserted in frozen water, then the body of deliquescing in frozen water is stretched into patient's trachea, the memory effect of the nationality memorial alloy under people's body temperature effect of the flexible pipe after inserting returns to original size, because hose body has certain hardness and rigidity under the supporting role of memory alloy stent, even if patient's dental articulation, hose body also remains unimpeded state, can effectively prevent that patient's tooth stings the phenomenon that tightly causes the inaccessible impact treatment of flexible pipe.
compared with prior art, beneficial effect of the present invention:the present invention is embedded with memory alloy stent at the tube wall of hose body, and the intensity of body is larger, and the support force of pipeline is better, can effectively prevent that the body causing because of patient's dental articulation is inaccessible.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of embodiment 2.
Labelling in figure: 1-hose body, 2-memory alloy stent.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
embodiment 1
As shown in Figure 1, the anti-interlock tracheal intubation of the present embodiment, comprises hose body 1, the tube wall of described hose body 1 is embedded with memory alloy stent 2, described memory alloy stent 2 is helical tubular structure, by the braiding of ti-ni shape memory alloy line, is formed, and the diameter of described ti-ni shape memory alloy line is 1.5mm.
The hose body 1 of the present embodiment has certain hardness and rigidity under the supporting role of memory alloy stent 2, even if patient's dental articulation, hose body 1 also remains unimpeded state, can effectively prevent that patient's tooth stings the phenomenon that tightly causes the inaccessible impact treatment of flexible pipe.
embodiment 2
As shown in Figure 2, the anti-interlock tracheal intubation of the present embodiment is with embodiment 1, difference is that it is that netted lattice pipe is netted that the tube wall of hose body 1 is embedded in memory alloy stent, described netted lattice circular tube structure memory alloy stent is formed by the braiding of ti-ni shape memory alloy line, due to network structure braiding get Geng Mi, the support strength of body is higher.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
Claims (3)
1. anti-interlock tracheal intubation, comprise hose body, it is characterized in that: the tube wall of described hose body is embedded with memory alloy stent, described memory alloy stent is formed by the thicker ti-ni shape memory alloy line braiding of diameter, and the diameter of described ti-ni shape memory alloy line is 0.5mm～2.5 mm.
2. anti-interlock tracheal intubation according to claim 1, is characterized in that: described memory alloy stent is helical tubular structure.
