Abstract
An improved structure for a nasopharyngeal airway comprises a soft plastic tube provided with side holes in the outer side wall, and is characterized in that an auxiliary soft plastic tube provided with side holes in the outer side wall penetrates in the main plastic tube provided with the side holes in the outer side wall, is propped against the inner side wall of the plastic tube and can rotate and move axially relative to the inner side wall of the plastic tube. Compared with the prior art, the improved structure for the nasopharyngeal airway has the advantages that the conditions of blockage and incapacity of smooth ventilation caused by collapse or flattening can be prevented, and blockages can be cleaned out and are not required to be taken out completely.
Description
Technical field:
The present invention relates to a kind of medical apparatus and instruments.
Background technology
No matter the patient such as pre hospital care and obstructive type sleep Apnea Syndrome low pass syndrome of Anesthesia Department, ICU, emergency department, the process of air flue and management are all important links, except needs medical worker has except professional technique, the medical device also needing safe and convenient helps.The process of difficult airway and Anesthetic safety and quality closely bound up, the success rate that more than 50% serious complication of anesthesia is given treatment to by improper other the clinical training critical patients caused of air flue according to statistics also has some relations with the quality of airway management.Nasopharyngeal air duct invented by Britain Anesthetist in 19th century, was used for the airway management of clinical anesthesia induction period and Anesthesia recovery stage patient.Existing nasopharyngeal air duct is many to be made up of soft silica gel or PVC material, and some nasopharyngeal air duct sidewalls are provided with perforation, to reduce the friction between plastic conduit lateral wall and nasal membrane, when avoiding it to insert nasal cavity, and damage nasal membrane.Though soft but easy pressure easy to break, easily flattened by Nasal packing material (hemostasis expandable sponges or nasal secretion) in nasal cavity section, or easily by glossoptosis and the pharyngeal cavity blocking of caving in or flatten after via intranasal application inlet port pharyngeal cavity, and, after blocking, only have and it is taken out from nasal cavity, could be totally clean by tamper, like this, one is difficult to reach the effect of ventilation smoothly, two often pick and place nasopharyngeal air duct, increase the probability of damage nasal membrane, also bring very large inconvenience to user.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of and can prevents from causing because caving in or flatten blocking, can not ventilate smoothly, tamper can be removed, the modified node method of the nasopharyngeal air duct that it need not be taken out completely again.
The present invention realizes like this, comprise the main plastic conduit of soft lateral wall with side opening, its special feature is that in plastic conduit cross-under has soft lateral wall with the secondary plastic conduit of side opening, and secondary plastic conduit to be close on plastic conduit medial wall and can be rotated and move axially by opposed plastic insides of pipes wall.
During use, secondary plastic conduit can not only play the effect of supporting plastic pipeline, can also by making secondary plastic conduit side opening, side opening is even closed by the aperture that plastic conduit side opening staggers to reduce side opening mutually, like this, nasal mucosa can be allowed by side opening humidifying suction gas, the too fast plastic conduit that enters of too much nasal secretion is avoided to block air flue, simultaneously, do not needing often to insert, when taking out plastic conduit, nasal secretion is removed by taking out secondary plastic conduit, nasopharynx is caused to lead to the generation of nose ulcers in order to avoid insert plastic conduit for a long time or repeatedly.
Here, be provided with cleaner, cleaner comprises the diameter tubule less than soft plastic conduit, number bundle can the stainless steel silk of folding and unfolding bending, the bending end of stainless steel silk is positioned at the outside of tubule, and the another two ends of stainless steel silk are through tubule.Pull outward the another two ends of stainless steel silk, and the bending end of stainless steel silk is moved toward tubule, and under the constraint of tubule, bending end shrinks, like this, the bending end of stainless steel silk just can extend into by Nasal packing material place through soft plastic conduit, is pulled out by these Nasal packing material.
The present invention compared with the prior art, have can prevent from causing because caving in or flatten blocking, can not ventilate smoothly, tamper can be removed, the advantage it need not taken out completely again.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation after each component separates.
Detailed description of the invention:
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
As shown in the figure, bag front end of the present invention be oblique section 1, rear end with the edge of a wing 2 and lateral wall with the silica gel of the softness of side opening 8 or PVC plastic pipeline 3, its special feature be in plastic conduit 3 cross-under have soft lateral wall with side opening 9 and rear end with the secondary plastic conduit 11 on the edge of a wing 10, secondary plastic conduit 11 to lean against on plastic conduit 3 medial wall and can rotate and move axially in opposed plastic pipeline 3 medial wall.
In order to prevent being flattened by foreign body, be provided with a few elastic stainless steel circles 4 vertically inside soft plastic conduit 3 wall, elastic stainless steel circle 4 forms with soft plastic conduit 3 overall processing.A few elastic stainless steel circles 4 are stainless steel spring circles.
Be provided with cleaner 5, cleaner 5 comprises the stainless steel silk 7 of the diameter tubule 6 less than soft plastic conduit 3, the bending of number bundle, and the bending end 7a of stainless steel silk 7 is positioned at the outside of tubule 6, and the another two ends 7b of stainless steel silk 7 is through outside tubule 6, its end is connected with handle, to operate.
Claims (4)
1. the modified node method of nasopharyngeal air duct
,comprise the plastic conduit of soft lateral wall with side opening, it is characterized in that sidewall outside has soft lateral wall with the secondary plastic conduit of side opening with cross-under in the plastic conduit of side opening, secondary plastic conduit to lean against on plastic conduit medial wall and can rotate and move axially by opposed plastic insides of pipes wall.
2. the modified node method of nasopharyngeal air duct according to claim 1, it is characterized in that being provided with cleaner, cleaner comprises the stainless steel silk of the diameter tubule less than soft plastic conduit, the bending of number bundle, the bending end of stainless steel silk is positioned at the outside of tubule, and the another two ends of stainless steel silk are through tubule.
3. the modified node method of nasopharyngeal air duct according to claim 1 and 2, it is characterized in that being provided with a few elastic stainless steel circles vertically inside soft plastic conduit wall, elastic stainless steel circle forms with soft plastic conduit overall processing.
