Abstract
The invention discloses a kind of trachea cannulas with ultra-thin sacculus, including conduit, sacculus and gas tube, the sacculus is arranged in tube at one end, described gas tube one end is communicated with sacculus, the other end is connect with external inflation equipment, the wall thickness in the inflated portion is less than 0.1mm, and the wall thickness of the sacculus fixed part is less than 0.3mm.Using the present invention, stimulation of the sacculus to tracheal wall when reducing insertion conduit, and due to being bonded sacculus using heat pressing process, it avoids that the organic matters such as cyclohexanone has been used to be bonded, increases the biocompatibility of trachea cannula.
Description
Technical field
The present invention relates to a kind of trachea cannula more particularly to a kind of trachea cannulas with ultra-thin sacculus.
Background technique
Existing trachea cannula generally comprises a conduit for being inserted into patient's trachea, and catheter head is equipped with for sealing
The sacculus in gap between conduit and patient's trachea wall is closed, is equipped with gas tube in catheter wall, gas tube one end is communicated with sacculus, is inflated
The pipe other end is drawn from catheter tail for connecting with external inflation equipment, and when conduit is not inserted into patient's trachea, sacculus is listless flat
State, after conduit is inserted into patient's trachea, by gas tube to inflated, sacculus is bonded with patient's trachea wall, plays anti-leak-stopping
Gas and prevent the effect accidentally inhaled after oropharyngeal secretions and gastric content reflux.Its sacculus of traditional trachea cannula by glue with
Bonding catheter, the wall thickness in inflated portion are more than or equal to 0.1mm, and the wall thickness of sacculus fixed part is more than or equal to 0.3mm, and sacculus is fixed
Portion and conduit connection have obvious ladder, and since conventional balloon is using elasticity and the lesser PVC material of toughness, ball
Capsule must reach the shapes and sizes after inflation at the time of molding, and along with air bag wall thickness is larger, this will cause sacculus in listless flat shape
There is gauffer and protrusion under state, to cause centainly injury or sense of discomfort to patient's trachea.
Summary of the invention
In order to solve the above-mentioned technical problem, the purpose of the present invention is to provide a kind of trachea cannula with ultra-thin sacculus,
Stimulation of the air bag when being inserted into patient's trachea to tracheal wall can be reduced.
The present invention is achieved through the following technical solutions:A kind of trachea cannula with ultra-thin sacculus, including conduit, sacculus
And gas tube, the sacculus are arranged in tube at one end, described gas tube one end is communicated with sacculus, the other end and external inflation equipment
Connection, the wall thickness in the inflated portion are less than 0.1mm, and the wall thickness of the sacculus fixed part is less than 0.3mm.
Wherein, the wall thickness in the inflated portion is 0.03mm, and the wall thickness of the sacculus fixed part is 0.06-0.1mm.
The sacculus is made of elastic material.
The sacculus is made of TPU material.
The sacculus is made up of extrusion moulding and blow molding.
The sacculus is arranged around the conduit.
The internal diameter of the sacculus fixed part is equal to catheter outer diameter.
The sacculus is hot bonding on conduit.
The longitudinal length of the sacculus fixed part is not less than 5mm.
A kind of trachea cannula with ultra-thin sacculus of the invention, has the advantages that:Sacculus wall thickness is smaller, and
Sacculus is bonded on conduit using heat pressing process, the bonding site of sacculus and conduit not will form apparent ladder;Sacculus makes
It is made of TPU (thermoplastic polyurethane elastomer rubber) material of elasticity, sacculus is at the time of molding without necessarily achieving the shape after inflation
And size, sacculus fold and protrusion will not occur under listless flat state, thorn of the sacculus to tracheal wall when reducing insertion conduit
Swash;It is bonded using heat pressing process, avoids that the organic matters such as cyclohexanone has been used to be bonded, increase the bio-compatible of trachea cannula
Property.
Detailed description of the invention
It, below will be to required in embodiment or description of the prior art in order to illustrate more clearly of technical solution of the present invention
The attached drawing used is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, right
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
Its attached drawing.
Fig. 1 is a kind of structural schematic diagram of the trachea cannula with ultra-thin sacculus of the present invention.
Fig. 2 is a kind of sacculus longitudinal sectional view of the trachea cannula with ultra-thin sacculus of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, carries out to the technical solution in inventive embodiments clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, those of ordinary skill in the art's every other reality obtained without making creative work
Example is applied, shall fall within the protection scope of the present invention.
Reference book attached drawing 1 and attached drawing 2, a kind of trachea cannula with ultra-thin sacculus of the invention, including conduit 1,
Sacculus 2 and gas tube 3, wherein:
1 front end of conduit has tip 4, and rear end is connected with connector 5;
Sacculus 2 is made of elastic material, is circumferentially positioned at the rear portion of catheter tip 4, and the wall thickness in inflated portion 21 is small
It is less than 0.3mm in the wall thickness of 0.1mm, sacculus fixed part 22, the longitudinal length of sacculus fixed part 22 is not less than 5mm;
3 one end of gas tube is arranged in sacculus 2, and the other end is connect with extension tube 6, and 6 tail end of extension tube is connected with check valve
Connector 7.
Preferably, the wall thickness in inflated portion 21 is 0.03mm, and the wall thickness of sacculus fixed part 22 is 0.06-0.1mm.
Preferably, the longitudinal length of sacculus fixed part 22 is 5mm.
Preferably, sacculus 2 is made of TPU material.
Prepare above-mentioned sacculus 2 in two steps, first step extrusion moulding squeezes out the embryonic tube of sacculus 2, and the internal diameter of embryonic tube is equal to conduit
