Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of novel single channel laryngeal mask.
Background technology
Laryngeal mask is a kind of breathing instrument maintaining the breathing of unconscious patients liquor-saturated patient as whole body grinds.The airbag inflation pipe of existing laryngeal mask is what to separate with laryngeal mask gas tube, during Clinical practice, it is inserted in human organ together, disclosed in Authorization Notice No. CN202236740U " Special laryngeal mask for bronchus ", it comprises by laryngeal mask snorkel, be incorporated into laryngeal mask snorkel end air bag and for airbag aeration and the airbag inflation pipe be connected with air bag form, and on laryngeal mask snorkel, be arranged side by side an inspection pipeline, this inspection pipeline is connected with air bag, the feature of this patent formula is: on air bag, connect the inspection pipeline parallel with laryngeal mask snorkel can provide convenience for bronchoscopic inspection, but show in this patent that its laryngeal mask gas tube and laryngeal mask conduit are provided separately, be independent of each other, and for example application publication number CN103316411A disclosed " laryngeal mask ", it is characterized in that: the other end of airbag inflation pipe and the laryngeal mask gas tube tube wall of laryngeal mask gas tube are structure as a whole, but this patent airbag inflation pipe removes one end and laryngeal mask gas tube tube wall is structure as a whole, and other are similarly the two passes be provided separately.
In addition, its laryngeal mask gas tube of existing laryngeal mask is thinner, generally can not insert the larger sputum aspirator tube of caliber simultaneously, therefore, laryngeal mask can not be used for tracheal suction and Intratracheal administration, needs that trachea aspirates, newborn with heavy asphyxia needs laryngeal mask can not be used to recover when Intratracheal administration or the situation such as external chest compression, pneumorrhagia at Meconium-stained Amniotic Fluid.
Utility model content
For overcoming the above problems, this utility model provides a kind of novel single channel laryngeal mask, comprises air bag, paster, conduit, bite-block, gas tube, joint; The paster be out of shape after preventing airbag aeration is provided with in the middle of described air bag, described conduit comprises the first venting cavity, the second venting cavity, inflatable chamber, one end of described conduit connects air bag, inflatable chamber one end of this conduit and airbags lead to, the other end connects gas tube by gas tube joint, the other end of described gas tube is connected with instruction sacculus, and this instruction sacculus is also connected with check valve;
The conduit outer wall of the other end of described conduit is provided with the bite-block that can reduce airway obstruction, have A/C effect, the other end of described conduit is also connected with the joint that can be connected the external airway of various standard.
First venting cavity of described conduit or the pore diameter range of the second venting cavity are 4.5mm to 13.5mm, are generally and are greater than conventional FR12 sputum aspirator tube diameter.
Described paster is blade type, its area and air bag inner chamber in the same size, described paster one end is provided with two symmetrical sector opens.
Described conduit first venting cavity is positioned at the left side of the second venting cavity, and described inflatable chamber is positioned at the right side of the second venting cavity, described first venting cavity, the second venting cavity and the separate setting of inflatable chamber.
As preferably, described guiding-tube bend degree is 90-120 degree knuckle, one-shot forming, and high strength and deformation.
As preferably, described air bag, conduit, paster, pilot balloon, gas tube all adopt soft silica gel material to make.
The beneficial effects of the utility model: 1, gas tube and laryngeal mask gas tube are set to the different chamber of same conduit by this utility model, when laryngeal mask is inserted in patient body, greatly reduce the sense of discomfort of patient, and too increase the convenience that medical personnel operate in use, simultaneously because inflatable chamber of the present utility model is in catheter interior, stop, because external gas tube is comparatively thin, in use easily causes fracture and cause the problem that air bag can not normally be inflated; 2, conduit of the present utility model adopts two venting cavities to arrange, one of them ventilation chamber can insert sputum aspirator tube, laryngeal mask is possessed when Meconium-stained Amniotic Fluid needs that trachea aspirates, newborn with heavy asphyxia needs Intratracheal administration or the situation such as external chest compression, pneumorrhagia, uses it to carry out the function of recovering; 3, this utility model increases paster in air bag, and air bag can be made not yielding when inflating, and air bag can be made better to fit with venturi, adds effectiveness and the safety of laryngeal mask use.
