Abstract
The utility model discloses a closed laryngeal mask of esophagus. The closed laryngeal mask of the esophagus is characterized in that one end of a breathing tube is connected with an external breathing machine, and another opening part in the other end of the breathing tube is a loudspeaker-shaped and connected with an annular balloon; the annular balloon is a coil surrounded with a hollow pipe body; a tube body is internally communicated with a balloon aeration valve and an aeration tube which are used to feed air into the annular balloon to enable the annular balloon to be expanded; one end of an esophagus suction tube passes through a tube body of the annular balloon and then is sequentially connected with an esophageal tube, an esophageal closed balloon and an esophageal tube opening; the esophageal suction tube is also communicated with the closed balloon aeration valve and the aeration pipe which are used to exhaust the input air from the esophagus tube opening; a stomach tube can extend from the esophagus tube and then extends from the esophagus tube opening. The closed laryngeal mask of the esophagus has the beneficial effects that the esophagus can be effectively closed to avoid the risks like stomach distention, reflowing and aspiration.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of esophagus closed formula laryngeal mask.
Background technology
In use Shortcomings of existing laryngeal mask: 1) the tightness risk that (especially in the time that position changes) exists mistake to inhale not of air flue sealing; 2) in the time of airway resistance or C variation, easily cause flatulence, affect operation technique or increase the chance that stomach backflows, mistake is inhaled.
Utility model content
The purpose of this utility model is providing a kind of esophagus closed formula laryngeal mask, has solved the inadequate problem of tightness of existing air flue sealing.
The technical scheme that this utility model adopts is to comprise breather, breather one end opening can connect outside respirator, other end peristome is that horn-like opening is connected with laryngeal mask annular air-pocket, laryngeal mask annular air-pocket is enclosed to the opening parcel coming, laryngeal mask annular air-pocket is the circle shape that hollow body surrounds, body internal communication laryngeal mask air chamber gas charging valve and gas tube, laryngeal mask air chamber gas charging valve and gas tube can be sent into gas laryngeal mask annular air-pocket expands laryngeal mask annular air-pocket, esophagus suction tube one end also connects esophageal tube successively through the body of laryngeal mask annular air-pocket, esophagus closed air bag and esophageal tube opening, esophagus suction tube is also communicated with Esophageal atresia air chamber gas charging valve and gas tube, Esophageal atresia air chamber gas charging valve and gas tube can be discharged the gas of input by esophageal tube opening, stomach tube can stretch into and stretch out from esophageal tube opening from esophagus suction tube.
Further, laryngeal mask annular air-pocket adopts silica gel.
The beneficial effects of the utility model are that esophagus closed formula laryngeal mask can effectively seal esophagus, avoid flatulence, backflow and the risk of by mistake inhaling.
Brief description of the drawings
Fig. 1 is a kind of esophagus closed formula of this utility model laryngeal mask structural representation;
Fig. 2 is that this utility model is applied to venturi schematic diagram.
In figure, 1. breather, 2. esophagus suction tube, 3. laryngeal mask air chamber gas charging valve and gas tube, 4. Esophageal atresia air chamber gas charging valve and gas tube, 5. horn-like opening, 6. laryngeal mask annular air-pocket, 7. esophageal tube, 8. esophagus closed air bag, 9. esophageal tube opening, 10. esophagus, 11. air flues.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is elaborated.
This utility model as shown in Figure 1, comprise breather 1, breather 1 one end openings can connect outside respirator, other end peristome is that horn-like opening 5 is connected with laryngeal mask annular air-pocket 6, laryngeal mask annular air-pocket 6 is enclosed to the opening parcel coming, the circle shape that laryngeal mask annular air-pocket 6 surrounds for hollow body, body internal communication laryngeal mask air chamber gas charging valve and gas tube 3, laryngeal mask air chamber gas charging valve and gas tube 3 can be sent into gas laryngeal mask annular air-pocket 6 expands laryngeal mask annular air-pocket 6, esophagus suction tube 2 one end also connect esophageal tube 7 successively through the body of laryngeal mask annular air-pocket 6, esophagus closed air bag 8 and esophageal tube opening 9, esophagus suction tube 2 is also communicated with Esophageal atresia air chamber gas charging valve and gas tube 4, Esophageal atresia air chamber gas charging valve and gas tube 4 can be discharged the gas of input by esophageal tube opening 9, stomach tube can stretch into and stretch out from esophageal tube opening 9 from esophagus suction tube 2.
Further, laryngeal mask annular air-pocket 6 adopts silica gel.
Using state as shown in Figure 2, laryngeal mask annular air-pocket 6 is connected with horn-like opening 5, makes 6 expansions by laryngeal mask air chamber gas charging valve and gas tube inflation 3 inflations, forms semi-enclosed airway, and breather 1 joins and realizes the interior ventilation of air flue 11 with respirator; Esophageal tube 7 is put into esophagus 10 with esophagus closed air bag 8 simultaneously, inflates by laryngeal mask air chamber gas charging valve and gas tube 3, and esophagus closed air bag 8 is expanded, sealing esophagus; Stomach tube can be inserted by esophagus suction tube 2, through esophageal tube opening 9, enter esophagus 10 simultaneously.
This utility model entirety adopts elastomeric material, such as silica gel, rubber etc. are made, can drain gastric gas, liquid, and also can effectively seal esophagus, avoid flatulence, backflow and risk that mistake is inhaled.
