Background

Endotracheal intubation general anesthesia is the operation anesthesia method commonly used, need the patient to open the mouth greatly when the intubate, make things convenient for the doctor to carry out the intubate, but because the stimulation during the intubate, the patient can be by the autonomic interlock that carries on, influence doctor's intubate operation, consequently, need the mouth gag to support patient's oral area, but after the intubate is accomplished, for avoiding the patient to open a mouthful and lead to facial muscle strain swelling for a long time, need take off the mouth gag, it prevents that the patient from biting the intubate to change the bite-block, then fix the medical sticky tape of intubate on the bite-block, but this kind of mode intubate is fixed insecure, shift easily, and it is troublesome to change the bite-block and fix the.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming the defect of prior art, the utility model provides an opener for anesthesia intubate, the effectual opener is used inconveniently when having solved present anesthesia intubate, the fixed insecure problem of intubate.

The technical scheme includes that the mouth gag for the anesthesia intubation comprises an upper U-shaped rod and a lower U-shaped rod, wherein openings of the two U-shaped rods are oppositely arranged, the lower U-shaped rod is of a hollow structure, two arms of the upper U-shaped rod penetrate through the two arms of the lower U-shaped rod and are attached to the inner wall of the lower U-shaped rod, the upper U-shaped rod can slide up and down, an air inlet pipe communicated with the inside of the lower U-shaped rod is installed on the side wall of the lower U-shaped rod, the outer end of the air inlet pipe is connected with a pressing type air bag, a check valve capable of introducing air into the lower U-shaped rod is installed on the air inlet pipe, an air outlet branch pipe located between the check valve and the lower U-shaped rod is communicated with the air inlet; the inner side of the lower U-shaped rod is fixed with a major arc-shaped fixing ring, a radial threaded rod is installed on the fixing ring, and the inner end of the threaded rod extends into the fixing ring and is provided with an arc-shaped pressing plate.

The utility model discloses can prop open patient's mouth type by a wide margin when the intubate, can make patient's mouth type interlock to relative comfortable size again after the intubate is accomplished, can carry out effectual fixing to the intubate simultaneously.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 6, the utility model comprises an upper U-shaped rod 1 and a lower U-shaped rod 2, two openings of the two U-shaped rods are arranged oppositely, the lower U-shaped rod 2 is of a hollow structure, two arms of the upper U-shaped rod 1 are penetrated in two arms of the lower U-shaped rod 2 and are attached to the inner wall of the lower U-shaped rod 2, the upper U-shaped rod 1 can slide up and down, an air inlet pipe 3 communicated with the inside of the lower U-shaped rod 2 is arranged on the side wall of the lower U-shaped rod 2, the outer end of the air inlet pipe 3 is connected with a push type air bag 4, a check valve 5 capable of introducing air into the lower U-shaped rod 2 is arranged on the air inlet pipe 3, an air outlet branch pipe 6 positioned between the check valve 5 and the lower U-shaped rod 2 is communicated on; the inner side of the lower U-shaped rod 2 is fixed with a major arc-shaped fixing ring 8, the fixing ring 8 is provided with a radial threaded rod 9, and the inner end of the threaded rod 9 extends into the fixing ring 8 and is provided with an arc-shaped pressing plate 10.

And the top of the upper U-shaped rod 1 and the bottom of the lower U-shaped rod 2 are both provided with a rubber strip 11.

The sections of the two rubber strips 11 are both U-shaped grooves, and the notches face outwards.

And limiting plates 12 capable of preventing the upper U-shaped rod 1 from slipping are mounted at two ends of the lower U-shaped rod 2.

The pressing type air bag 4 and the air inlet pipe 3 are detachably connected through a plug-in type medical connector 13.

When the utility model is used, firstly, the pressing type air bag 4 is connected with the air inlet pipe 3 and the switch valve 7 is closed, then the air bag is repeatedly pressed to inflate the air bag into the downward U-shaped rod 2, the air pressure in the lower U-shaped rod 2 rises to push the upper U-shaped rod 1 to move upwards, so that the support ring formed by the two U-shaped rods is enlarged until the size of the support ring is matched with the mouth shape of a patient, then the support ring is arranged in the mouth of the patient, the upper teeth and the lower teeth of the patient are respectively bitten into the U grooves of the upper rubber strip 11 and the lower rubber strip 11, the teeth of the patient are supported to enlarge the mouth cavity of the patient, then the pressing type air bag 4 can be taken down, after the mouth cavity of the patient is enlarged, a doctor can perform intubation, after the intubation is completed, the intubation is blocked into the fixing ring 8 from the notch of the fixing ring 8, then the screw rod 9 is cured inwards, the air in the lower U-shaped rod 2 is slowly exhausted, the upper U-shaped rod 1 moves downwards under the occlusion force of a patient, the supporting ring is reduced, the opening amplitude of the patient is reduced, and when the patient is occluded to a relatively comfortable degree, the switch valve 7 is closed.

The utility model discloses can be applicable to the patient of equidimension mouth type not, can prop open patient's mouth type by a wide margin when the intubate, can make patient's mouth type interlock to relative comfortable size after the intubate is accomplished again, and can not open a mouthful for a long time and make facial muscle strain sour bloated, also can avoid the patient to bite into the intubate, can carry out effectual fixing to the intubate simultaneously.
