Description

Antiskid of removable oropharynx air vent takes off fixer

Technical Field

The utility model relates to a medical fixer especially discloses a fixer is taken off in antiskid of removable oropharynx air vent.

Background

The oropharynx air duct is a non-tracheal catheter non-invasive air duct, can prevent tongue from falling backward, quickly opens the air duct and achieves effective ventilation. For anesthetized or comatose patients, the tongue and epiglottis may fall back into the posterior pharyngeal wall, causing obstruction of the upper airway, due to the relaxation of the muscles of the floor of the mouth and pharynx that support the tongue to maintain the patency of the upper airway. When correctly inserted into the oropharyngeal airway, the front end of the device can lift the tongue and the epiglottis from the posterior pharyngeal wall, thereby achieving the purpose of preventing or treating the upper respiratory obstruction. Compared with other methods for maintaining the patency of the upper respiratory tract, such as chin lifting and tracheal intubation, the stability of the cervical vertebra of the patient is not affected by inserting the oropharyngeal airway.

However, in the use of the oropharyngeal airway, when the patient is irritated or the head position is changed, the situation that the oropharyngeal airway is shifted, separated or slipped off from the oral cavity and the like is easy to happen; in order to prevent this, the adhesive tape is usually used to stick and fix the external portion of the oropharyngeal airway to the face of the patient, and the patient often moves to pull the adhesive tape, so that the adhesive tape is not ideal in fixation effect and troublesome in sticking, and the oropharyngeal airway cannot be properly fixed. When a patient with thick sputum and large sputum amount encounters, the oropharynx air duct is often obstructed or blocked, if the oropharynx air duct is not replaced in time, adverse consequences can be generated, and the replacement of the adhesive tape can also cause certain damage to the skin of the patient.

In order to improve the defects of the adhesive plaster, if the fixing baffle plate at the front end of the oropharyngeal airway is directly provided with structures such as the fixing belt, the oropharyngeal airway is further fixed after being fixed on the brain of a patient through the fixing belt, because the oropharyngeal airway needs to be replaced in use, the additionally generated structures can only be replaced along with the oropharyngeal airway, so that the resource waste is caused, and meanwhile, the production cost of the oropharyngeal airway is further improved; in addition, when changing the oropharynx air vent, the fixed band structure of oropharynx air vent is dismantled together with the same needs, and in the dismantlement and the change process, patient's head position changes inevitably, can cause to change inconveniently equally, arouse patient's mood dysphoria scheduling problem.

Disclosure of Invention

An object of the utility model is to overcome the defect that exists among the prior art, provide one kind and effectively prevent oropharynx air vent slippage, make the antiskid of changing more convenient, safe in utilization's removable oropharynx air vent take off the fixer.

The utility model discloses a realize like this: an anti-slip fixer with a replaceable oropharynx air duct comprises an oral cavity baffle and an adjustable fixing band, wherein a notch used for clamping and embedding the oropharynx air duct is formed in the middle of the oral cavity baffle downwards from the edge of the upper side, a limiting strip used for limiting the oropharynx air duct to move up and down is arranged on the upper portion of the notch, one end of the limiting strip is rotatably connected with the oral cavity baffle through a rotating shaft, an elastic buckle is arranged at the other end of the limiting strip, and a protrusion corresponding to the elastic buckle is arranged on the oral cavity baffle; the both sides of oral cavity baffle are equipped with respectively and connect the waist hole, the both ends of adjustable fixed band with connect the waist hole and can dismantle continuously.

The two ends of the adjustable fixing band are respectively provided with a self-adhesive button, and the two ends of the adjustable fixing band respectively penetrate through the waist connecting holes on the two sides of the oral baffle and then are fixedly connected and formed through the self-adhesive buttons to be detachably connected.

And a first pressure reducing pad is arranged on the inner side surface of the middle part of the adjustable fixing band.

And a second pressure reducing pad is arranged on the inner side surface of the oral baffle.

The lower side edge of the limiting strip is provided with a limiting opening matched with the shape of the top of the oropharynx air duct.

The oropharynx air duct comprises an arc-shaped air duct, a through air pipe and a fixed baffle which are sequentially connected, the through air pipe is positioned in the notch and is tightly matched with the inner wall of the notch, the fixed baffle is positioned on the outer side of the oral baffle and is in contact with the outer surface of the oral baffle, and the limiting strip is positioned above the fixed baffle.

The first pressure reduction pad is a polyester foam dressing pressure reduction pad.

The second pressure reduction pad is a polyester foam dressing pressure reduction pad.

The utility model has the advantages that: through adjustable fixed band will the oral cavity baffle is fixed at patient's oral area, the oral cavity baffle passes through the fixed oropharynx air duct of notch, further restricts the removal of oropharynx air duct through spacing, the one end of spacing through the pivot with the oral cavity baffle is rotatory continuous, the other end of spacing passes through elasticity buckle and arch and links to each other with the oral cavity baffle, makes things convenient for spacing to open through rotatory mode for oropharynx air duct takes out or puts into conveniently from the notch, and the oropharynx air duct of being convenient for changes at any time to guarantee that it effectively ventilates, and need not to take off oral cavity baffle and adjustable fixed band, prevent that patient's head from taking place the unnecessary and removing. The tightness of the adjustable fixing band can be adjusted through the self-adhesive buckles at the two ends of the adjustable fixing band, so that the adjustable fixing band is suitable for different patients. Through first decompression pad, second decompression pad are reducible the utility model discloses to the oppression damage of patient's skin.
