Abstract
The utility model discloses a novel throat shield, comprising a shield, an aeration vent, and an air conduct pipe and a gullet drainage tube on the shield. A cushion is arranged on the back of the shield. The utility model aims at overcoming the defect of prior throat shield air-breather and providing a new throat shield with better tightness and fine quality of air-breathing that is not breakable during insertion.
Description
Technical field
This utility model relates to medical instruments field, and particularly a kind of patient who is used for surgery anesthesia, critical patient rescue or other assisted respiartions sets up the laryngeal mask of artificial airway's ventilation.
Background technology
In order to keep unconscious patient respiration ventilation, must set up respiration channel to it.Traditional mode is to use tracheal intubation.But there is big defective in tracheal intubation: at first be to be difficult to fast and suitably pipeline to be inserted trachea, because this is a kind of processing procedure of high-tech very, will be toward contact by devices such as laryngoscopes, and must have the operator of certain technology to implement, so this mode some need in the patient body, to set up as early as possible respiration channel with the situation of striving for treatment time under beneficial effect be not clearly; Secondly, tracheal intubation in use easily causes people's cardiopulmonary reaction, throat pain, cough or laryngospasm etc., and since need control when inserting patient and cervical region, make patient's neck also may come to harm; In addition, insert for convenience, the distal dimension of tracheal intubation must be enough little, and this just makes that the respiration channel that produces is less or narrower.
The eighties in 20th century, British Brain has proposed the notion of laryngeal mask, the air flue apparatus that laryngeal mask is made up of the silicone cover and the rubber linking tube of an inflatable leaves shape.Behind its insertion bottleneck throat, give the laryngeal mask airbag aeration, expansible laryngeal mask air bag can hold and seal epiglottis and glottis, forms the annular seal space of a low pressure around larynx, and the laryngeal mask connection tube leads to and can link to each other with respirator outside the oral cavity, but autonomous respiration or positive airway pressure.Laryngeal mask is a kind of safer airway than face shield, is airway management technology on a kind of real glottis.Anesthesia doctor through training generally believes slotting laryngeal mask than the easier grasp of endotracheal intubation technology, and it can successfully be inserted under the flat state that crouches and lie on one's side.
Afterwards, on the basis of above-mentioned laryngeal mask again improvement esophagus conduction type laryngeal mask appearred.The characteristics of this laryngeal mask are: increase the esophagus drainage tube that parallels with airway, can insert suction catheter esophageal reflux thing and gastric content are carried out drain, perhaps carry out artificial enteral nutritional support where necessary, so just increased the safety that laryngeal mask uses; In addition, increased the back air bag, formed double-air sac structure, made cover body and patient throat fit closelyr after the inflation, improved sealing, improved the artificial ventilation quality at the back of throat's cover body.
But existing laryngeal mask also has its defective: as shown in Figure 2, because the back air bag adopts silicone rubber mostly, air-tightness is relatively poor, easily gas leakage; In addition, according to some clinical researches, because the laryngeal mask back is soft, special under the state of unaerated, turn down easily during insertion, therefore the clinical literature introduction portion gas that prestores in the air bag of back is earlier arranged, take place to reduce turnover, if but this also have in the clinical literature introduction laryngeal mask simultaneously residual gas arranged, laryngeal mask is most advanced and sophisticated to become big, can increase the incidence rate of turning under the epiglottis, perhaps through hard palate the time, increase the folding incidence rate of laryngeal mask.
Summary of the invention
The purpose of this utility model is the defective that overcomes existing laryngeal mask airway device, provides a kind of and has than high leakproofness, and be difficult for during insertion turning down, the measured novel laryngeal mask of ventilation matter.
This utility model is achieved by the following technical programs:
A kind of novel laryngeal mask comprises air-filled pore, airway tube and esophagus drainage catheter on laryngeal mask body, the laryngeal mask body, and the back of described laryngeal mask body is provided with cushion.
Described cushion is located in the inside interlayer at laryngeal mask body back.
That described laryngeal mask body comprises is inflatable/utricule of bleeding and the back cover body that is arranged on the utricule, and described cushion is located in the inside interlayer of back cover body.
That described laryngeal mask body comprises is inflatable/utricule of bleeding and the back cover body that is arranged on the utricule, and described cushion is located at the outer surface of back cover body.
Described cushion and back cover body are one-body molded.
That described laryngeal mask body comprises is inflatable/utricule of bleeding and the back cover body that is arranged on the utricule, and described cushion is located at the inner surface of back cover body.
Described cushion and back cover body are one-body molded.
Described inflatable/utricule and the back cover body of bleeding are one-body molded.
That air-filled pore on the described laryngeal mask body is located at is inflatable/the utricule surface of bleeding.
This utility model improves the back of existing laryngeal mask, and a cushion is located at the back of laryngeal mask, makes the back of laryngeal mask flexible, and the back air bag need not be set.Cushion in this utility model both can play the effect of back air bag in the prior art, and it is tightr that laryngeal mask back and patient throat are fitted, and sealing property is more superior, can exempt the risk of back air bag from back gas leakage again.In addition, laryngeal mask back cushion can make laryngeal mask under the situation of no inner residual gas, has both kept most advanced and sophisticated thin thin, easily by patient epiglottis portion, can strengthen the intensity of laryngeal mask simultaneously again, reduces the generation probability of laryngeal mask turnover during insertion.
Description of drawings
Fig. 1 this utility model structural representation;
The profile of air bag cover body in Fig. 2 prior art;
The profile of Fig. 3 this utility model air bag cover body.
The specific embodiment
As shown in Figure 1, this utility model comprises inflatable/utricule 1, the air-filled pore 2 on the utricule 1, back cover body 3, airway tube 4 and esophagus drainage catheter 5 of bleeding.
Utricule 1 inside is communicated with air-filled pore 2, and air-filled pore 2 is connected with inflating catheter.
As shown in Figure 3, the inflatable/utricule 1 of bleeding is provided with back cover body 3.Cushion 6 is located in the inside interlayer of back cover body 3.Its implementation can adopt: the laryngeal mask back in prior art covers cushion 6, and its external lamella parcel also is bonded in the laryngeal mask back.Its implementation also can adopt back cover body 3 and cushion 6 one-body molded.
Perhaps, cushion 6 is located at the outer surface of back cover body 3.Cushion 6 directly is pasted on the outer surface of back cover body 3, or cushion 6 and back cover body 3 are one-body molded.
Or cushion 6 is located at the inner surface of back cover body 3.Cushion 6 directly is pasted on the inner surface of back cover body 3, or cushion 6 and back cover body 3 are one-body molded.
