Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to the artificial respiration in management of respiratory field
Road apparatus.
Background technology
At clinical respiratory management domain, build people frequently with artificial airway's series products such as laryngeal mask, tracheal intubation
Work air flue.This utility model relates generally to laryngeal mask series products, and laryngeal mask conventional clinically can be divided into single-chamber laryngeal mask
And two-chamber larynx cover.
Single-chamber laryngeal mask is mainly by air bag, airway tube, catheter adapter, gas tube, instruction vesicle, check valve
Deng composition.During clinical practice, after inserting laryngeal mask and positioning, utilize aerating device through check valve in gas tube
Perfusion air, after airbag aeration connect with gas tube, expansion, holds and seals epiglottis and glottis after expansion,
Form the seal closure of a low pressure around larynx, then the equipment end of throat cover air flue conduit pipe is connect by conduit
Head is connected with respirator, thus helps patient to realize autonomous respiration or mechanical assistance positive airway pressure.Two-chamber larynx cover
Compare with single-chamber laryngeal mask and mainly add drainage tube, be mainly used in patient during laryngeal mask uses and occur that stomach returns
Attract the gastric juice backflowed during stream, prevent gastric juice from entering pulmonary.
At present, the laryngeal mask used clinically mostly be non-plastotype laryngeal mask, i.e. laryngeal mask airway tube axis place put down
Face and laryngeal mask opening place plane are substantially in 180 °～210 ° of angles.During Clinical practice, angle need to be carried out
Degree adjusts, and inserting and positioning needs certain time, disposably inserts success rate the highest, simultaneously because larynx
The material that cover uses is that macromolecular material has certain elasticity, there may be certain after carrying out angle adjustment
, there is certain compressing to the tissue of force part in resilience force.
It addition, for two-chamber larynx cover, the drainage tube of increase can be prevented effectively from because stomach backflows the mistake caused
Air draught danger, but on producing, the structure of product is more complicated than the laryngeal mask without drainage tube, especially air bag and backboard
Technique for sticking on, need the drainage tube increasing by one section of through backboard end to tongue-like part, the most common life
Production. art is to be bonded in inside backboard by one section of drainage tube, the open side that i.e. backboard encloses towards laryngeal mask air bag,
This drainage tube length just connects the conduit of backboard end and connects seat and the drainage tube opening part of tongue-like part, then
Air bag is bonding with backboard more bonding with airway tube, drainage tube and loading line, thus complete laryngeal mask
Assembling, this technique for sticking relates to the bonding of multiple parts, and processing step is complicated, the process time is long, good
Product rate is low.
Utility model content
This utility model aims to provide a kind of pre-plastotype laryngeal mask, the management of respiratory neck for clinical emergency treatment field
Territory, can effectively shorten clinical intubation time, improve disposable successful intubation.Above-mentioned purpose is by with lower section
Case realizes:
A kind of pre-plastotype laryngeal mask, including air bag, gas tube, airway tube and backboard, air bag is by the week of backboard
Edge extension encloses and forms, and gas tube one end is connected with air bag inner chamber, and airway tube one end connects with the opening of air bag
Connect；It is characterized in that: airway tube is being provided with bending section at air bag, and bending section angle is 90 °～130
°。
As further technical scheme, the described gas tube other end is disposed with instruction vesicle and check valve.
As further technical scheme, the other end of described airway tube is provided with the conduit connecting respirator
Joint.
As further technical scheme, described pre-plastotype laryngeal mask also includes outside drainage tube, balloon segment drain
Pipe and connection seat, balloon segment drainage tube is positioned at inside backboard, through backboard longitudinal length, backboard and balloon segment
Drainage tube is one-body molded；Connect seat and be fixedly installed on backboard one end, connect be provided with on seat the first connector and
Second connector, described airway tube one end connects with the first connector being connected seat, and this first connector enters
And be connected with the opening of air bag, connect the second connector of seat by one end of outside drainage tube and balloon segment drain
One end of pipe connects, and it is most advanced and sophisticated that the other end of balloon segment drainage tube is opened on backboard tongue-like part.
It is arranged in parallel as further technical scheme, described airway tube and outside drainage tube, outside drain
Pipe is being provided with bending section at air bag, and bending section angle is 90 °～130 °.
As further technical scheme, between described airway tube and outside drainage tube, it is provided with fixation clamp.
The pre-plastotype laryngeal mask that this utility model provides, the bending section angle of the patient end preformed of its airway tube is
90 °～130 °, so that airway tube main body place axial plane and the angle of air bag opening place plane
Being 90 °～130 °, this angle meets the angle of physiology in human body laryngopharynx portion physiology curve oral cavity and throat,
In use can quickly position, shorten intubation time, reduce patient suffering.Above-mentioned pre-plastotype structure is also
May be used for two-chamber larynx cover, i.e. airway tube and outside drainage tube be arranged in parallel, and outside drainage tube is near gas
It is 90 °～the bending section of 130 ° that Nang Chu arranges angle equally.
