Abstract
The utility model relates to a medical instrument for building an air duct, in particular to a safe leakage-free tracheal catheter. The safe leakage-free tracheal catheter comprises a ventilation conduit and pressure bladders, wherein the ventilation conduit comprises a conduit and a fixed wing that is arranged at the air inlet of the conduit; each pressure bladder comprises four ring-shaped gas pockets, two inflation tubes and exhaust tubes, two indication gas pockets and two non-return valves, wherein the four ring-shaped gas pockets are arranged near the outer wall at the outlet end of the conduit in sequence, two middle ring-shaped gas pockets are respectively connected with the alternative ring-shaped gas pockets in series to form two groups of ring-shaped gas pockets, and are connected to different indication gas pockets and different non-return valves through different inflation tubes and exhaust tubes respectively to form two sets of independent pressure bladders to be sealed reliably; and the safe leakage-free tracheal catheter adopting the technical proposal has safety in use and small compression on the tracheal wall.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments of setting up air flue, relates in particular to a kind of gas conduit of removing the trachea retentate.
Background technology
In the clinical rescue operation of respiratory failure, usually to use the endotracheal tube of setting up interim air flue.All have closed airbag on the conventional endotracheal tube, the effect of air bag mainly is the gap between sealing endotracheal tube and the trachea, to intercept the thing that backflows of pharyngeal secretions stomach function regulating esophagus.But, cause that more retentate is arranged on the air bag owing to do not have the air communication mistake on the air bag.Because the change of patient's breathing, position, air flue caliber change, the decline of gasbag pressure and every day the air flue nursing need air bag charge and discharge gas, cause air bag well not seal and trachea between the gap, cause these to have the rheuminess thing of high concentration pathogenic microorganism, entering bronchus from the gap drip between air bag and the trachea---lung, this is very easy to cause respirator dependency pneumonia or respirator dependency pneumonia takes place repeatedly.A plurality of researchs find that also retentate and respirator dependency pneumonia have substantial connection on the capsule, thereby cause the clinical treatment failure.
The utility model content
The technical problems to be solved in the utility model provides a kind of lasting cleaning air flue, reduces the accumulative novel endotracheal tube of rheuminess thing.
In order to solve the problems of the technologies described above, this utility model provides a kind of novel endotracheal tube, includes catheter main body and the union joint that is arranged on the catheter main body inlet end, and the outlet side tube wall of described catheter main body circumferentially is provided with a plurality of ventholes.
Adopt the novel endotracheal tube of technique scheme, owing to cancelled traditional air bag in order to the sealing trachea, and set out pore in original balloon positions, the purging air flue that the air-flow of venthole continues, until the rheuminess thing on the air flue is blown to the oral cavity, and removed, guaranteed the unobstructed of air flue, the bronchus of having avoided rheuminess thing drip to arrive simultaneously.
As preferred version, consider the intensity of venthole place catheter main body, and the venthole air-flow to the rheuminess thing continue blow, described venthole distributes along the outlet side tube wall spiral of catheter main body.
As preferred version, in order further to improve the blow effect of venthole air-flow to the rheuminess thing, described venthole diameter is 3mm, and adjacent venthole is 2cm at the axial spacing of catheter main body, is 120 ° at the radially angle of catheter main body.
As preferred version, take all factors into consideration cost and result of use, limiting described venthole number is 6, the spacing of bottommost venthole and catheter main body outlet side is 3.5cm.
Description of drawings
Fig. 1 is the sketch map of this utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, this utility model provides a kind of novel endotracheal tube, include catheter main body 1 and the union joint 2 that is arranged on catheter main body 1 inlet end, the outlet side tube wall of catheter main body 1 circumferentially is provided with 6 ventholes 3, venthole 3 distributes along the outlet side tube wall spiral of catheter main body 1, the diameter of venthole 3 is 3mm, adjacent venthole 3 is 2cm at the axial spacing of catheter main body 1, radially angle at catheter main body 1 is 120 °, and bottommost venthole 3 is 3.5cm with the spacing of catheter main body 1 outlet side.
During use, endotracheal tube is inserted into the trachea assigned address, and the connection air feed equipment carries out air feed, portion gas continues ejection from venthole 3, air flue intercepts air flue, simultaneously with the rheuminess thing, be blown into the oral cavity such as expectorant from trachea, be convenient to take out expectorant, can reach lasting cleaning air flue like this, reduce the accumulative effect of rheuminess thing.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from this utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that this utility model is implemented.
