Abstract
The invention relates to a medical flexible tube, in particular to a trachea cannula, which comprises a flexible tube body, wherein the tooth biting area of a patient at the outer side of the flexible tube body is sheathed with a hard tube, and the interior of the wall of the flexible tube is embedded with a spiral memory alloy line. The trachea cannula has the advantages that the outer side of the flexible tube is sheathed with the hard tube; after the cannula is inserted into the body of the patient, the hard tube is arranged in the tooth biting area of the patient, so the problem of blockage of the flexible tube due to the tight biting of teeth during the therapy of the patient is effectively prevented, the whole structure is simple, and the convenience and practicality are realized; the titanium-nickel memory alloy material embedded into the wall of the flexible tube has the characteristics of high strength, good toughness, corrosion resistance, no poisonous and side effects, long-term contact with people, and super-flexible support force and restoration force, the memory alloy material is conveniently arranged in the trachea, and the certain force is applied to the expansion part during the shape restoration, so the falling is avoided.
Description
Technical field
The present invention relates to flexible pipe for medical purpose, particularly 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.When running into pernicious or benign tumor and cause that patient airway blocks, due to airway narrows, common trachea is difficult to by the narrow positions of blocking in addition.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art, provide a kind of convenience successfully to insert trachea, and can effectively expand the not caducous anti-interlock tracheal intubation of narrow positions.
For achieving the above object, the invention provides following technical scheme:
Tracheal intubation, comprises hose body, and in hose body outside, patient's tooth is stung nested domain and is connected to hard tube, and the tube wall of described hose body is embedded with and is shaped as spiral memorial alloy line.
In above-mentioned tracheal intubation, described memorial alloy line is helical tubular structure.
In above-mentioned tracheal intubation, described memorial alloy line is ti-ni shape memory alloy line.
In above-mentioned tracheal intubation, described hard tube can slide on hose body.
When clinical use, first the body that contains memorial alloy line is inserted in frozen water, then the body of deliquescing in frozen water is elongated so that reduced diameter, medical worker just can make reduced diameter but flexible pipe that body has extended passes through the narrow positions of patient's trachea easily like this.The memory effect of the nationality memorial alloy under people's body temperature effect of the flexible pipe after inserting returns to clinical needed size, and produces certain power when recovering, thereby narrow positions is expanded.
compared with prior art, beneficial effect of the present invention:the present invention has been socketed one section of hard tube in the outside of flexible pipe, after body is inserted in patient body, hard tube is arranged at patient's tooth and stings region, effective like this prevented patient when treatment tooth tightly sting the problem that causes hose body obturation, total is simple, convenient and practical.The ti-ni shape memory alloy strength of materials that the tube wall of hose body is embedded in is high, good toughness, corrosion-resistant, have no side effect, can contact with people for a long time, memorial alloy has super-elasticity support force and restoring force, conveniently insert trachea, when recovering shape, there is certain masterpiece to be used in expansion position, therefore should not come off.

Fig. 2 is the structural representation of hose body in the present invention.
Fig. 3 is the contraction state figure of hose body.
Labelling in figure: 1-hose body, 2-hard tube, 3-ti-ni shape memory alloy line.
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 accompanying drawing 1, accompanying drawing 2, the tracheal intubation of the present embodiment, comprises hose body 1, in hose body outside, patient's tooth is stung nested domain and is connected to hard tube 2, and the tube wall of described hose body 1 is embedded with the ti-ni shape memory alloy line 3 that is shaped as helical tubular structure, and described hard tube 2 can slide on hose body 1.
During use, hose body 1 is inserted in patient body, 2 sections of hard tubes are adjusted in to patient's tooth and sting region, when to patient treatment, make hose body 1 remain unimpeded state like this, effectively prevented that patient's tooth tightly stings the phenomenon that causes the inaccessible impact treatment of flexible pipe.As shown in Figure 3, when airway obstruction patient is used, first the body that contains memorial alloy line is inserted in frozen water, then the body of deliquescing in frozen water is elongated so that reduced diameter, medical worker just can make reduced diameter but flexible pipe that body has extended passes through the narrow positions of patient's trachea easily like this.The memory effect of the nationality memorial alloy under people's body temperature effect of the flexible pipe after inserting returns to clinical needed size, and produces certain power when recovering, thereby narrow positions is expanded.
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 (4)
