Abstract
The utility model relates to a laryngeal mask. The utility model is composed of a venting catheter and an inflatable mask which forms an ellipse at a far end, wherein a brim of the inflatable mask is provided with an air sac, an air sac seat is arranged on an inner circle of the air sac, a venthole is arranged on the air sac seat which is communicated with the venting catheter, and an outer brim of the air sac is communicated with an inflating tubule, an inflating tubule indicating sac and a one-way valve; a helical reinforcing lining is inserted in the wall of the venting catheter, and an included angle is formed between the head end of the venting catheter and the inflatable mask. The utility model has the advantages that tube bodies have suitable flexibility, the helical reinforcing lining can strengthen the intensity of the tube wall of the venting catheter, and the venting catheter still keeps an unobstructed state when the venting catheter is bent in arbitrary directions or patients bite the venting catheter with teeth; the laryngeal mask can be safely and rapidly placed into patients'throats, stimulation for the patients is small when the laryngeal mask is placed and the mechanical obstruction of a respiratory tract is little. The utility model can be used for the patients in conventional operations, and the utility model which can be used as an emergent air passage processing device can be used for the patients in the difficulty of endotracheal intubation or the first aid of cardiopulmonary resuscitation.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to a kind of laryngeal mask of using when surgery anesthesia and critical patient rescue cheap and easy and simple to handle.
Background technology
In clinical rescue cardiopulmonary arrest patient, the patient of cardio-pulmonary resuscitation especially, setting up effective artificial airway in the very first time has crucial meaning to improving salvage success rate.Need perform the operation and when accepting general anesthesia, for keeping its respiratory ventilation, needs of patients is accepted the air flue blood processor patient, as tracheal intubation and breathing mask etc., in the aforementioned means use, cause patient's cardiopulmonary reaction easily, cough or laryngospasm; Tracheal intubation not only needs higher technology and time-consuming longer, in the field first aid of racing against time, has often delayed valuable time; And can not carry out owing to block on the glottis for those pulmonary ventilation and some anatomic abnormalities can not the patient of intubate for, adopting laryngeal mask is their first-selection as artificial respiration's air flue.In nearly ten years, laryngeal mask successfully is applied to the patient of a large amount of difficult airways, because common laryngeal mask airway conduit is soft, in use soft durometer is difficult to take into account, and is stung tight back generation luminal stenosis phenomenon by patient easily in ventilation is kept; The making material selection silicone rubber of laryngeal mask in addition, cost is higher, is unfavorable for disposable use, thereby can not solve the aleopation problem preferably.
Summary of the invention
This utility model provides a kind of laryngeal mask rational in infrastructure, cheap and easy and simple to handle for solving the technical problem that exists in the known technology.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
Laryngeal mask, be to be ovate inflatable cover by an airway and one of far-end to constitute, inflatable cover is made of hollow cylindrical air bag and the angled air bag seat that has passage on it, airway is communicated with inflatable cover, the air bag outward flange is communicated with gas tube, inflation indication capsule and check valve, it is characterized in that: in described airway wall, be embedded with a shape reinforcing line in the shape of a spiral, form an angle between the air bag seat of described airway head end and inflatable cover, this angle angle is 25 °～40 °.
This utility model can also adopt following technical measures:
Described inflatable cover, airway and inflation tubule all adopt nontoxic PVC material to make.
Described reinforcing line is made by stainless steel silk.
Advantage and the good effect that the utlity model has are: because this utility model is embedded with rustless steel spiral reinforcing line in the airway wall, not only can strengthen the intensity of airway tube wall, but also can prevent that the patient who is in non-waking state stings tightly, to keep the airway tube chamber state that keeps clear; This laryngeal mask can safety quickly be inserted patient's laryngopharynx, and the stimulation to patient when inserting is little, and respiratory tract mechanical obstruction is few, and caused cardiovascular system reacts less when inserting and extracting, and complication is few; This laryngeal mask is cheap in addition, can both can be used for the routine operation patient for disposable use, can be used as urgent air flue blood processor again and is used for the patient that tracheal intubation meets with difficulty or cardio-pulmonary resuscitation first aid.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the K of Fig. 1 is to view.
Among the figure: 1 inflatable cover, 1-1 air bag, 1-2 air bag seat, 1-3 air bag seat passage, 2 airways, 2-1 spiral reinforcing line, 3 gas tubes, 4 inflation indication capsules, 5 check valves.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of laryngeal mask, be to be ovate inflatable cover 1 by an airway 2 and one of far-end to constitute, inflatable cover is made of hollow cylindrical air bag 1-1 and the air bag seat 1-2 that has passage 1-3 on it angled with it, airway is communicated with inflatable cover, the air bag outward flange is communicated with gas tube 3, the gas tube other end is connected with inflation indication capsule 4 and check valve 5, for the intensity that strengthens the airway tube wall so that operator insert patient's laryngopharynx safely and fast with laryngeal mask, with keep the laryngeal mask airway conduit cavity and be in unobstructed state, be embedded with a shape reinforcing line 2-1 in the shape of a spiral in the tube wall of described airway 2, described reinforcing line is made by stainless steel silk.Form an angle between described airway head end and the inflatable cover, the angle of this angle is preferably 30 °.
Operation principle of the present utility model is as follows:
By gas tube 3, inflation indication capsule 4 and check valve 5 air bag 1-1 is exitted earlier, back with inflatable cover 1 is butted on patient's hard palate again, exert pressure inflatable cover 1 is sent into laryngopharynx, place on the glottis, thereafter by gas tube 3, inflation indication capsule 4 and 5 pairs of airbag aerations of check valve, after the inflation, inflatable cover 1 is full of by the profile of laryngopharynx and forms sealing.Airway is connected with artificial respirator implements the artificial ventilation breathing.
