Abstract

The utility model relates to a medical inflatable-free boot-shaped throat cover which is used for ventilating for a patient during anaesthesia and emergency process, and the throat cover is characterized in that the throat cover is composed of a boot-shaped cover, a ventilation pipe and a built-in esophagus pipe, wherein, the boot-shaped cover is provided with an arc-shaped apophysis, ventilation holes, an esophagus pipe and an esophagus hole by which the esophagus pipe can enter the esophagus; the built-in esophagus pipe is divided into three parts which respectively are a built-in esophagus pipe head part, a built-in esophagus pipe neck part and a built-in esophagus pipe throat part. The root-shaped throat cover has the advantages that the throat cover accords with the oriental dissection structure of throats, spares a ventilation device, not only has simpler operation, but also avoids dangers of respiratory tract obstruction caused by folding and over inflatable for a common throat cover; a flat ventilation tract not only prevents the ventilation pipe and the esophagus pipe from being bitten by the teeth of the patient, but also increases stability of the throat cover. The built-in esophagus pipe not only can lead esophagus reflux but also can judge that if the boot-shaped cover can be effectively sealed with throat or not, so mistake respiration rate can be reduced.

Description

Inflation-free boot last laryngeal mask

Technical field

This utility model relates to a kind of inflation-free boot last laryngeal mask that is used to anaesthetize and gives patient ventilating during first aid.

Background technology

Clinically when using laryngeal mask to give patient ventilating, because of vent hood and throat airtight not exclusively, folding, hyperinflation take place in laryngeal mask, cause that flatulence, mistake are inhaled, anti-complication such as stream and respiratory tract obstruction, and these complication are easy to the danger that causes patient death or cause aspiration pneumonitis.

The utility model content

This utility model can effectively prevent the generation of above-mentioned complication, provide a kind of be applied to anaesthetize or first aid in keep the unobstructed inflation-free boot last laryngeal mask of patient respiration.

The technical scheme in the invention for solving the technical problem is:

A kind of inflation-free boot last laryngeal mask, it comprises boot-shaped cover, breather, embedded food meatus.The boot-shaped cover offers esophagus hole and the passage that leads to esophagus, and it is arcuate ridge that a projection is arranged on the boot last cover, and it makes boot last cover and human body bottleneck throat structure more identical.There is joint the breather upper end, and there is embedding place of embedded food meatus the joint below, and body the widest part is the dental articulation place.Embedded food meatus divides three sections, and it before the pneumatic duct tube wall is embedded food meatus head that joint below embeds, and what embed that pneumatic duct tube wall and pneumatic duct go together is embedded food meatus cervical region, and the part in boot last cover 1 is an embedded food meatus throat.

Inflation-free boot last laryngeal mask of the present utility model, can not only effectively separate air flue and the convenient anatomical structure of ventilating and more meeting Asians's bottleneck throat than common laryngeal mask of esophagus owing to be provided with the boot last cover, save aerating device, not only operate simple and fast more and avoided common laryngeal mask that the danger that folding and hyperinflation causes respiratory tract obstruction takes place, arcuate ridge on the boot last cover, it and human body epiglottis portion match, more effectively the closed vent road; The flat airway both can prevent that patient's tooth is stung and close breather and food meatus, can increase the stability of laryngeal mask again; But embedded food meatus setting is drain esophageal regurgitation thing but also can judge the boot last cover and whether throat has reached effective airtight not only, thereby has reduced the probability that mistake is inhaled; Therefore inflation-free boot last laryngeal mask has simple to operate, safer and clinical application range characteristic more widely.

The specific embodiment

As Figure 1-3, a kind of inflation-free boot last laryngeal mask of the present utility model, it comprises boot-shaped cover 1, breather 2, embedded food meatus 3.Boot-shaped cover 1 offers esophagus hole 1-1 and the passage 1-2 that leads to esophagus, and it is arcuate ridge 1-3 that a projection is arranged on the boot last cover 1, and it makes boot last cover and human body bottleneck throat structure more identical.There is joint 2-1 breather 2 upper ends, and there is embedding place of embedded food meatus 3 the joint below, and body the widest part is the 2-2 of dental articulation place.It before the pneumatic duct 2 is embedded food meatus head 3-1 that three sections of embedded food meatus 3 minutes, joint 2-1 below embed, and that embed that pneumatic duct 2 and pneumatic duct 2 go together is embedded food meatus cervical region 3-2, and the part in boot last cover 1 is the embedded food meatus 3-3 of throat.

Shown in Fig. 4-7, the embedded food meatus 3-3 of throat of the present utility model leans on position intermediate in the bottom of boot-shaped cover 1, to prevent to influence normal ventilation.

Inflation-free boot last laryngeal mask described in the utility model inserts patient's bottleneck throat by the doctor with boot last cover 1 in use and determines behind the position joint 2-1 is connected with oxygen unit and get final product.

Inflation-free boot last laryngeal mask described in the utility model is simple to operate, has overcome the shortcoming of common laryngeal mask, has reduced the generation of complication such as anti-stream, mistake suction, respiratory tract obstruction, flatulence.In addition, inflation-free boot last laryngeal mask has the specifications and models that vary in size according to patient age, body weight etc., to adapt to the patient of all ages and classes, body weight.

More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
