Abstract
The invention relates to a medical hose, in particular to a trachea cannula with a memory alloy tent. The trachea cannula with the memory alloy tent comprises a hose body, wherein the memory alloy tent is embedded in the pipe wall of the hose body. The trachea cannula has the advantages that the memory alloy tent is embedded in the pipe wall of the hose body, the intensity of the hose body is great, and the pipeline support force is better; memory alloy ware has hyperelastic support force and recovery force, the trachea cannula can be conveniently placed into the narrow trachea, and certain force exerts on the expansion part during the shape recovery, so the falling cannot easily occur.
Description
Technical field
The present invention relates to flexible pipe for medical purpose, particularly a kind of tracheal intubation with memory alloy stent.
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 the good toughness of body makes bulk strength, winding degree poor, and the support force of pipeline is not strong, easily causes stopping up again of respiratory tract; 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 pipeline support intensity large, and can effectively expand the not caducous tracheal intubation of narrow positions.
For achieving the above object, the invention provides following technical scheme:
Tracheal intubation with memory alloy stent, comprises hose body, and the tube wall of described hose body is embedded with memory alloy stent.
In the above-mentioned tracheal intubation with memory alloy stent, described memory alloy stent is helical tubular structure.
In the above-mentioned tracheal intubation with memory alloy stent, described memory alloy stent is netted lattice circular tube structure.
In the above-mentioned tracheal intubation with memory alloy stent, described memory alloy stent is formed by the braiding of ti-ni shape memory alloy line.
When clinical use, first the hose body that contains memory alloy stent is inserted in frozen water, then the body of deliquescing in frozen water is elongated so that reduced diameter, like this medical worker just can make reduced diameter but flexible pipe that body has extended easily by the narrow positions of 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 clinical needed size, and produce certain power when recovering, thereby narrow positions is expanded.
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; Memorial alloy has super-elasticity support force and restoring force, can conveniently insert narrower trachea, has certain masterpiece to be used in expansion position, therefore should not come off when recovering shape.

Fig. 3 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 tracheal intubation of the present embodiment band memory alloy stent, comprises hose body 1, and the tube wall of described hose body 1 is embedded with the memory alloy stent 2 that is shaped as helical tubular structure.
The present embodiment is because the tube wall at hose body 1 is embedded with memory alloy stent 2, and hose body 1 is under the supporting role of support, and the intensity of body is larger, and the support force of pipeline is better, and body can not be out of shape obstruction because of compression extruding, and then causes stopping up again of respiratory tract, as shown in Figure 2, when running into pernicious or benign tumor and cause that patient airway blocks, first the hose body that contains memory alloy stent 1 is inserted in frozen water, then the body of deliquescing in frozen water is elongated so that reduced diameter, like this medical worker just can make reduced diameter but flexible pipe that body has extended easily by the narrow positions of 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 clinical needed size, and when recovering, produce certain power, thereby narrow positions is expanded, body also should not be come off.
embodiment 2
As shown in Figure 3, the tracheal intubation of the present embodiment band memory alloy stent is with embodiment 1, difference is that the tube wall of described hose body is embedded with the memory alloy stent that is shaped as netted lattice circular tube structure, described netted lattice circular tube structure memory alloy stent is formed by the braiding of ti-ni shape memory alloy line, in medical frozen water, can elongate equally.
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)
1. with the tracheal intubation of memory alloy stent, comprise hose body, it is characterized in that: the tube wall of described hose body is embedded with memory alloy stent.
2. the tracheal intubation with memory alloy stent according to claim 1, is characterized in that: described memory alloy stent is helical tubular structure.
3. the tracheal intubation with memory alloy stent according to claim 1, is characterized in that: described memory alloy stent is netted lattice circular tube structure.
4. according to the tracheal intubation with memory alloy stent described in claim 2 or 3, it is characterized in that: described memory alloy stent is formed by the braiding of ti-ni shape memory alloy line.
