The present invention provides a kind of laryngeal mask manufacturing methods comprising following steps: manufacturing the whole mould for air bag to be made
The inside of tool, mold is equipped with step；Mold is put into PVC slurry；It takes out mold and is put into hot briquetting in heater box；It takes out into
Air bag after type and the surface that gas-guide tube is fixed on to step；Step another surface opening and take out mold；And envelope
Make and break mouth.
The present invention also provides another laryngeal mask manufacturing methods comprising following steps: manufacture is for being made the whole of air bag
The inside of mould, mold is equipped with step；Preheated mold；Mold after preheating is put into PVC slurry；It takes out mold and is put into and add
Hot briquetting in hot tank；It takes out air bag after molding and gas-guide tube is fixed on to a surface of step；In another table of step
Face is open and takes out mold；And closing opening.
Wherein, mold is fixed on a surface of step by glue.
Wherein, opening is closed by glue.
Wherein, the temperature in heater box is the temperature of PVC maturation.
The present invention also provides a kind of laryngeal masks made of above-mentioned laryngeal mask manufacturing method.
Laryngeal mask manufacturing method of the invention, does not have spue line using gasbag outer surface made of unitary mould, solves existing
Have by gasbag outer surface made of blow molding mode there is spue line, which not accommodate caused by patient, in technology damages trunnion
The problem of.
Detailed description of the invention

Specific embodiment
Please refer to Fig. 1, Fig. 3 and Fig. 4,100 manufacturing method of laryngeal mask that the first embodiment of the invention provides, including it is as follows
Step: in a step 101, the unitary mould 200 for air bag 20 to be made is manufactured, the inside of mold 200 is equipped with step 202；?
In step 102, mold 200 is put into polyvinyl chloride (Polyvinylchloride, PVC) slurry；In step 103, mould is taken out
Tool 200 is simultaneously put into hot briquetting in heater box；At step 104, it takes out air bag 20 after molding and is fixed on gas-guide tube 10
One surface of step 202；In step 105, in another surface opening of step 202 and mold 200 is taken out；And in step
In 106, closing opening.
In the present embodiment, the shape of mold 200 is consistent with the shape of air bag 20.When mold 200 is put into PVC slurry in
After further taking out, molding just generates air bag 20 after remaining PVC slurry is heated on mold 200.
It because mold 200 of the invention is unitary mould, i.e., is not separated upper/lower die, to pass through this unitary mould
The outer surface of air bag 20 made of 200 does not have spue line.When laryngeal mask 100 is inserted into patient's throat, patient will not feel like oneself,
Will not injured patients' trunnion, solve in the prior art because the spue line of 20 outer surface of air bag is not accommodating to larynx caused by patient
The problem of pipe damages.
Further, when gas-guide tube 10 to be fixed on to a surface of step 202, mold 200 inside air bag 20, thus
The step 202 of 200 support air bag 20 of mold is conducive to the surface that gas-guide tube 10 is fixed on step 202.Moreover, when closing
When opening, 10 support level 202 of gas-guide tube is conducive to the closing of opening.
In the present embodiment, mold 200 is fixed on a surface of step 202 by glue, and opening passes through mucilage sealing
It closes.Step 202 is located at the inside approximately mid way between of mold 200.
In the present embodiment, mold 200 is hollow.
In the present embodiment, heater box is oven.
The thickness of air bag 20 is related with the concentration that PVC is starched, if PVC slurry is denseer, the thickness of air bag 20 is relatively thick, such as
Fruit PVC slurry is diluter, then the thickness of air bag 20 is relatively thin.That is, in the first embodiment, passing through the dense of PVC slurry
The thickness of degree control air bag 20.
In the present embodiment, the temperature that mold 200 heats is the temperature of PVC maturation, such as 120 degree to 130 degree.Together
When, the temperature that mold 200 heats is related with the PVC concentration starched and environment temperature.
Fig. 2 to Fig. 4 is please referred to, for 100 manufacturing method of laryngeal mask that second of embodiment of the invention provides, second of implementation
100 manufacturing method of laryngeal mask of mode is similar with 100 manufacturing method of laryngeal mask of the first embodiment, and can reach essentially identical
Technical effect.100 manufacturing method of laryngeal mask of second of embodiment includes the following steps: in step 301, to manufacture for being made
The inside of the unitary mould 200 of air bag 20, mold 200 is equipped with step 202；In step 302, preheated mold 200；In step
In 303, the mold 200 after preheating is put into PVC slurry；In step 304, it takes out mold 200 and is put into heater box and heat
Molding；In step 305, it takes out air bag 20 after molding and gas-guide tube 10 is fixed on to a surface of step 202；In step
In 306, step 202 another surface opening and take out mold 200；And in step 307, closing opening.
In the second embodiment, in the identical situation of PVC slurry concentration, air bag 20 is controlled by preheated mold 200
Thickness.The temperature that mold 200 preheats is higher, and the thickness of air bag 20 is thinner.Meanwhile mold preheating temperature lower than PVC starch at
Ripe temperature.Further, when the thickness of air bag 20 impregnates in PVC slurry with the thickness of mold 200, environment temperature and mold 200
Between it is related.
Referring to FIG. 4, the present invention also provides a kind of laryngeal mask 100 made of the above method, laryngeal mask 100 of the invention
Including gas-guide tube 10, air bag 20 and gas tube 30, air bag 20 is located at the end of gas-guide tube 10, and gas tube 30 is connected to air bag 20.
20 outer surface of air bag made of the above method through the invention does not have spue line, to prevented in use because of air bag
The spue line of 20 outer surfaces discomfort caused by patient, and prevent the damage caused by patient's trunnion.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
