Abstract
The utility model relates to a disposal single-cavity silicon rubber laryngeal mask, which comprises a breathing conduit and an inflatable hood connected with the breathing conduit. The inflatable hood is integrally formed by a hollow cylindrical air bag and an air bag; the outer edge of the air bag is connected with an inflatable tube; a spiral stainless steel wire reinforcing lining is embedded in the tube wall of the breathing conduit; the inflatable hood and the breathing conduit are all made of silicon rubber material; and the breathing conduit is fixed connected with the inflatable hood by an annual lug boss and an annular groove which are arranged on the breathing conduit. The utility model has the advantages that: the structure design is reasonable, the tube body is soft and suitable, the manufacturing process is simplified and the cost is low; and the spiral reinforcing lining can enhance the strength of the conduit wall of the breathing conduit, so that the breathing conduit still keeps unobstructed state when the conduit is freely bent or is bitten by patients; the disposal single cavity silicon rubber laryngeal mask can be safely and quickly placed into the hypopharynx of patients, has small stimulation to the patients during placing and small mechanical obstruction of respiratory tract, not only can be used for routine operation patients, but also can be used as an emergency air duct treatment device for handling the situation when a tracheal cannula is difficult to carry out or the patients are in cardio-pulmonary resuscitation fist aid. The utility model brings the convenient to a laryngeal mask which is generally used in medical clinic application.
Description
Technical field
This utility model relates to a kind of being applied to and medium is imported the intravital device of people in the medical instruments field, a kind of specifically disposable single chamber silicone rubber laryngeal mask of using when surgery anesthesia or critical patient rescue.
Background technology
Laryngeal mask generally is used for clinical operation anesthesia and dangerous patient is rescued equipment such as replacing endotracheal intubation or breathing mask, when clinical use, it is inserted the air bag front end arrive UES from patient's mouth, through air valve by gas tube after the inflation of inflatable cover, the inflatable patient of covering on throat forms a ring packing, gas arrives the pulmonary of human body again by breather line, to pulmonary's air feed.
Present disposable single chamber silicone rubber laryngeal mask product comprises catheter interface, airway, jointing, inflatable cover, gas tube, indication vesicle, check valve; Catheter interface is arranged at the end of airway, and the other end of airway is connected with inflatable cover by jointing, and the other end of inflatable cover is connected with the indication vesicle by gas tube, and the other end of indication vesicle is connected with check valve.It is loosening that the defective of this series products is that the junction of inflatable in use cover and airway is prone to, and body is soft inadequately.
The utility model content
It is simple that the purpose of this utility model provides a kind of structural design, and the junction that remedies inflatable in use cover of existing product and airway is prone to disposable single chamber silicone rubber laryngeal mask of loosening defective.
Another purpose of the present utility model provides the soft suitable disposable single chamber silicone rubber laryngeal mask of a kind of body.
The technical scheme that its technical problem that solves this utility model adopts is: disposable single chamber silicone rubber laryngeal mask comprises check valve, indication vesicle, airway, inflatable cover, airway, catheter interface; Check valve is connected with airway by the indication vesicle, the other end of airway is connected with inflatable cover, so just gas can be sent in the inflatable cover, annular boss and airway fixed bonding that inflatable cover is provided with by annular recess on it and airway, inflatable cover is connected with airway closely, difficult drop-off, catheter interface are arranged at the end of airway, and airway is connected with artificial respirator.
Described inflatable cover consists of an integral body by hollow cylindrical air bag and air bag seat, annular boss and airway fixed bonding that air bag seat is provided with by annular recess on it and airway.
Described air bag composition surface is at the inner edge adhering and sealing.
Be embedded with shape stainless steel silk reinforcing line in the shape of a spiral in the tube wall of described airway, thereby make the airway state that when bending or patient's tooth are stung, still can keep clear arbitrarily.
The beneficial effects of the utility model are,
1. adopt the connected mode of concavo-convex cooperation owing to this utility model, thereby make inflatable cover be connected closely difficult drop-off with airway.
2. owing to be embedded with shape stainless steel silk reinforcing line in the shape of a spiral in the tube wall of airway, thereby make body soft suitable, at the airway state that when bending or patient's tooth are stung, still can keep clear arbitrarily.
3. owing to reduced the use of connector, thereby reduced cost, and simple in structure.
Description of drawings
Fig. 1 is a sketch map of the present utility model;
1. check valves among the figure, 2. indication vesicle, 3. airway, 4. inflatable cover, 41. hollow cylindrical air bags, 42. air bag seats, 421. annular recess, 43. inner edge composition surfaces, 5. airway, 51 annular boss, 6. catheter interface.
The specific embodiment
As shown in Figure 1, this utility model comprises check valve 1, indication vesicle 2, airway 3, inflatable cover 4, airway 5, catheter interface 6; Check valve 1 is connected with airway 3 by indication vesicle 2, the other end of airway 3 is connected with inflatable cover 4, so just gas can be sent in the inflatable cover 4, annular boss 51 and airway 5 fixed bondings that inflatable cover 4 is provided with by annular recess on it 421 and airway 5, inflatable cover 4 is connected with airway 5 closely, difficult drop-off, catheter interface 6 is arranged at the end of airway 5, and airway 5 is connected with artificial respirator.Inflatable in the present embodiment cover 4 consists of an integral body by hollow cylindrical air bag 41 and air bag seat 42.The composition surface of hollow cylindrical air bag 41 is at inner edge 43.Annular boss 51 and airway 5 fixed bondings that air bag seat 42 is provided with by annular recess on it 421 and airway 5.In order to make body soft suitable more, can in the tube wall of airway 5, be embedded with shape stainless steel silk reinforcing line in the shape of a spiral, thereby make airway 5 state that when bending or patient's tooth are stung, still can keep clear arbitrarily.
Operation principle of the present utility model is:
During use, by check valve 1, pilot balloon 2, gas tube 3 inflatable cover 4 is exitted earlier, back with inflatable cover 4 is lower than the hard Hubei Province of patient again, exert pressure inflatable cover 4 is sent into patient's laryngopharynx, place on the glottis, charge into quantitative gas by check valve 1, pilot balloon 2,3 pairs of inflatable bladder 4 of gas tube thereafter.The inflatable cover 4 in inflation back is full of by the profile of patient's laryngopharynx, and formation seals, airway 5 is connected the enforcement artificial ventilation and breathes with artificial respirator.
