Abstract
The utility model belongs to a medical appliance, in particular to a easy-operated laryngeal mask with low cost for anaesthetization in operation and the emergency treatment on the serious disease sufferers and comprises a breathing pipe made of innocuous PVC materials, a cover pocket made of silica gel materials, a gas-filled tube, an indicating air pocket and an one-way air valve; the cover pocket is connected with the breathing pipe, of which the other end is connected with an air source connecting terminal; the cover pocket is ovum round-shaped; the cover pocket is connected with the gas-filled tube, of which the other end is connected with an indicating air pocket; an one-way air valve is arranged on the indicating air pocket. The excellent biologic compatibility and sealability of the silica gel cover pocket can be ensured by using the laryngeal mask of the laryngeal mask, and the manufacturing cost of the breathing pipe and the laryngeal mask can be reduced at the same time; when in use, only the silica gel cover pocket is contacted with the parslaryngea pharyngs of human body; the biologic compatibility is good, so that the silica gel cover pocket can be attached on the parslaryngea pharyngs closely.
Description
Technical field
This utility model belongs to medical apparatus and instruments, particularly 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 safeguarding its respiratory ventilation, needs of patients is accepted the air flue blood processor patient, as tracheal intubation etc., but cause patient's cardiopulmonary reaction in the aforementioned means use easily, even cause respiratory tract injury; And, in the first aid process,, delay valuable time often because of the more high reason of its operating technology.Nowadays, laryngeal mask successfully is applied to surgery anesthesia and critical patient rescues, and is especially first-selected especially for the patient of a large amount of difficult airways.
At present, in laryngeal mask is made, make material and use silicone rubber more, though characteristics such as that silicone rubber has is nontoxic, bio-compatibility is good, its material cost is higher to be unfavorable for disposable use.Therefore some manufacturer uses nontoxic PVC to be making material laryngeal mask, but has lost the good characteristics of silicone rubber in order to reduce product cost, and the laryngeal mask of PVC material manufacture, also has and inserts the cunning that has some setbacks, characteristics such as cover capsule sealing difference.
The utility model content
This utility model is for addressing the above problem, and proposed a kind of new laryngeal mask structure and suitable material, thereby the production cost that greatly reduces laryngeal mask does not lose the good characteristics of silicone rubber again.
This utility model is to address the above problem the technical scheme that is adopted to be: laryngeal mask of the present utility model, it is characterized in that: it is mainly by the breather that uses nontoxic PVC as material, use silica gel to form as cover capsule, gas tube, pilot balloon and the Non-return air valve of material, the cover capsule is connected with breather, the other end of breather connects a gas source connector, and the cover capsule is an oval, connects gas tube on the cover capsule, the other end of gas tube connects pilot balloon, and Non-return air valve is installed on the pilot balloon.
The beneficial effects of the utility model are: laryngeal mask in use, the cover capsule is the part of main directly contact patient throat, and the breather that plays the ventilation effect does not directly contact with the human body throat, based on this handling characteristics, this utility model uses silica gel to use nontoxic PVC to make breather as material as material manufacturing cover capsule.Like this, with the full silica gel that uses as material or use nontoxic PVC to compare entirely as the laryngeal mask of material, laryngeal mask described in the utility model had both guaranteed the good bio-compatibility and the sealing of silica gel cover capsule, also reduce the manufacturing cost of breather simultaneously, thereby reduced the manufacturing cost of laryngeal mask.Laryngeal mask described in the utility model in use has only silica gel cover capsule to contact with the human body throat, and bio-compatibility is good, can closely attach with the throat.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Below in conjunction with the drawings and specific embodiments scheme of the present utility model is described in further detail.
See also shown in Figure 1ly, the structure of laryngeal mask is mainly by cover capsule 1, breather 2, and gas tube 3, pilot balloon 4, Non-return air valve 5, gas source connector 6 is formed; Its cover capsule 1, gas tube 2, pilot balloon 4 use the silica gel material, and breather 2 uses nontoxic PVC to make.Cover capsule 1 is connected with breather 2, and the other end of breather 2 connects a gas source connector 6.Breather is nontoxic PVC material, and body itself is curved to have a certain degree.The interior round center of cover capsule is provided with opening, and opening part can have barrier, also can not have barrier; Cover capsule 1 is an oval, connects gas tube 3 on the cover capsule, and the other end of gas tube 3 connects pilot balloon 4, and Non-return air valve 5 is installed on the pilot balloon 4.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1, a kind of laryngeal mask, it is characterized in that: it is mainly by the breather that uses nontoxic PVC as material, use silica gel to form as cover capsule, gas tube, pilot balloon and the Non-return air valve of material, the cover capsule is connected with breather, the other end of breather connects a gas source connector, and the cover capsule is an oval, connects gas tube on the cover capsule, the other end of gas tube connects pilot balloon, and Non-return air valve is installed on the pilot balloon.
