Abstract
The utility model relates to a medical soft tube, in particular to an anti-occlusion trachea cannula. The anti-occlusion trachea cannula comprises a soft tube body, wherein a memory alloy supporting frame is embedded inside the tube wall of the soft tube body, the memory alloy supporting frame is woven by titanium nickel memory alloy threads with a large diameter, and the diameter of each titanium nickel memory alloy thread is 0.5-2.5 mm. According to the anti-occlusion trachea cannula, the memory alloy supporting frame is embedded inside the tube wall of the soft tube body, the strength of the tube body is large, the supporting force of a tube is good, and tube body blockage caused by occlusion of teeth of a patient is effectively prevented.
Description
Technical field
This utility model relates to flexible pipe for medical purpose, particularly a kind of anti-interlock tracheal intubation.
Background technology
At present in patient with severe symptoms's treatment, inserting endotracheal tube through the oral cavity, 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 and inserts in patient's trachea through the oral cavity, and the patient is strengthened assisted respiartion.Because adapt to the flexibility of air flue in the human body, body in the above-mentioned insertion patient body select for use usually suppleness preferably material make, yet in actual use, after body being inserted in patient's body, because the phenomenon that tooth is tightly stung appears in patient easily in treatment, use the relatively poor body of rigidity easily by patient's dental articulation, cause the body obturation, cause to breathe and interrupt or liquid such as can't be input in patient's body at problem.
The utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of anti-interlock tracheal intubation is provided.
For achieving the above object, this utility model provides following technical scheme:
A kind of 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 the above-mentioned anti-interlock tracheal intubation, described memory alloy stent is helical tubular structure.
In the above-mentioned anti-interlock tracheal intubation, described memory alloy stent is netted lattice circular tube structure.
This utility model is embedded with memory alloy stent at the tube wall of hose body, described memory alloy stent adopts the thicker ti-ni shape memory alloy line of diameter to constitute, intensity and the support force of body are enhanced, in use, the hose body that will contain memory alloy stent is earlier inserted in the frozen water, then will be in frozen water the body of deliquescing stretch 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 rigidity and rigidity under the supporting role of memory alloy stent, even if patient's dental articulation, hose body also remains unimpeded state, can prevent effectively that patient's tooth stings the phenomenon that tightly causes the inaccessible influence treatment of flexible pipe.
Compared with prior art, the beneficial effects of the utility model:This utility model is embedded with memory alloy stent at the tube wall of hose body, and the intensity of body is bigger, and the support force of pipeline is better, can effectively prevent the body obturation that causes because of patient's dental articulation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of embodiment 2.
Labelling among the figure: 1-hose body, 2-memory alloy stent.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining this utility model, and be not used in restriction this utility model.
As shown in Figure 1, present embodiment is prevented the interlock tracheal intubation, 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, is formed by the braiding of ti-ni shape memory alloy line, and the diameter of described ti-ni shape memory alloy line is 1.5mm.
The hose body 1 of present embodiment has certain rigidity 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 prevent effectively that patient's tooth stings the phenomenon that tightly causes the inaccessible influence treatment of flexible pipe.
As shown in Figure 2, the anti-interlock tracheal intubation of 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, because network structure braiding De Gengmi, the support strength of body is more high.
The above only is preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
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, 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.
