Description

Oropharyngeal tube

Technical Field

The utility model relates to a medical auxiliary instrument, concretely relates to oropharyngeal tube.

Background

Oropharyngeal tube is a non-tracheal tube non-invasive ventilation tube, can prevent tongue tenesmus, open the air flue rapidly, obtain effectual ventilation, it is unobstructed to maintain the upper respiratory tract, to anesthesia patient or coma patient, because support tongue maintain the unobstructed end of the mouth of upper respiratory tract and pharyngeal muscle relaxation, tongue and epiglottis can fall into the pharyngeal back wall backward, thereby lead to the upper respiratory tract to be obstructed, when correct inserted mouth pharyngeal tube, its front end can be lifted tongue and epiglottis from the pharyngeal back wall, thereby reach the purpose of preventing or treating upper respiratory tract to be obstructed.

The existing oropharyngeal tube is provided with a baffle plate for blocking the mouth of a patient, so that the mouth is ensured to be opened, and the oropharyngeal tube is ensured to be unblocked; but also effectively prevent the oropharyngeal tube from moving to the oral cavity and causing damage to the patient. However, the existing baffle is made of too hard materials, is mostly made of plastic products, and is easy to cause pressure injury after being used for too long time.

Therefore, the oropharyngeal tube is designed, and the outer surface of the baffle is covered with the air bag, so that pressure injury is effectively prevented.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an oropharyngeal tube is provided, the one deck gasbag covers at the baffle surface, effectively prevents to weigh wounded.

In order to solve the technical problem, the utility model adopts the following technical scheme:

oropharyngeal tube, including breather pipe, baffle and gasbag circle, the baffle has front and reverse side, and the baffle middle part is equipped with the mounting hole that runs through, and breather pipe end is inserted in the mounting hole and rather than fixed connection by the front, and the gasbag circle encircles the setting of baffle edge and protrusion in front.

As a further improvement of the above technical solution:

the inner side of the air bag ring is internally provided with an annular groove, and the baffle plate can be clamped in the annular groove. The air bag ring is detachably arranged on the baffle, so that the air bag ring is convenient to detach and sterilize.

Furthermore, the ring channel comprises round hole and rectangular channel intercommunication, and the rectangular channel is inside setting by gasbag circle edge, and under the sufficient state of gasbag circle, baffle thickness is less than the round hole diameter and is greater than the rectangular channel width. When the air bag ring is inflated, the inner walls of the two sides of the rectangular groove are used for clamping the baffle, so that the air bag ring is more stably connected with the baffle. The design round hole increases the elasticity of ring channel, makes the baffle insert the innermost side of ring channel smoothly, improves the steadiness of being connected of gasbag circle and baffle.

Furthermore, the edge of the baffle protrudes outwards to form a clamping ring matched with the round hole, and after the baffle is clamped into the rectangular groove, the clamping ring is embedded into the round hole. The snap ring is embedded into the round hole, so that the connection between the air bag ring and the baffle is more stable.

Furthermore, the inner wall of the rectangular groove is covered with a layer of non-slip mat. Avoid the baffle to slide in the rectangular channel, make the connection of gasbag circle and baffle more firm.

The oropharyngeal tube also comprises a wide band, and two ends of the wide band are respectively positioned at two sides of the baffle and connected with the air bag ring. The broadband not only prevents that the breather pipe from breaking away from the patient oral cavity, presses the gasbag circle to patient's face moreover, is that the gasbag circle is laminated more and patient's face.

Further, the wide band is an elastic band.

A pressing piece used for fastening the air bag ring is connected between the baffle and the air bag ring, the pressing piece comprises a pressing plate and a rotating shaft, the pressing plate is rotatably sleeved on the rotating shaft, a threaded hole is formed in the reverse side of the baffle, one end of the rotating shaft is inserted into the threaded hole and is in threaded connection with the threaded hole, and the other end of the rotating shaft is fixedly connected with a handle; the handle is rotated, and the handle can press the pressing plate to the air bag ring. The casting die effectively prevents that the gasbag circle from breaking away from the baffle.

Compared with the prior art, the utility model has the advantages that:

marginal area is equipped with the gasbag circle around the above-mentioned baffle outside, gasbag circle protrusion in the front of baffle, makes gasbag circle and face in close contact with, avoids baffle direct contact face, effectively prevents to weigh wounded.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the technical solution of the present invention is given in conjunction with the accompanying drawings and the detailed description of the preferred embodiments.

As shown in fig. 1 to 4, the oropharyngeal tube of the embodiment includes a ventilation tube 1, a baffle 2 and an air bag ring 3, the baffle 2 has a front surface and a back surface, a through mounting hole is arranged in the middle of the baffle 2, the end of the ventilation tube 1 is inserted into the mounting hole from the front surface and is fixedly connected with the mounting hole, and the air bag ring 3 surrounds the edge of the baffle 2 and protrudes out of the front surface. An annular groove 31 is formed from the inner side of the air bag ring 3 to the inner side of the air bag ring, and the baffle 2 can be clamped in the annular groove 31. The annular groove 31 is formed by communicating a round hole 32 and a rectangular groove 33, the rectangular groove 33 is formed by arranging the edge of the air bag ring 3 inwards, and the thickness of the baffle 2 is smaller than the diameter of the round hole 32 and larger than the width of the rectangular groove 33 in the filling state of the air bag ring 3. The edge of the baffle plate 2 protrudes outwards to form a clamping ring 21 matched with the round hole 32, and after the baffle plate 2 is clamped into the rectangular groove 33, the clamping ring 21 is embedded into the round hole 32. The inner wall of the rectangular groove 33 is covered with a layer of non-slip mat. The oropharyngeal tube also comprises a wide band 4, and two ends of the wide band 4 are respectively positioned at two sides of the baffle 2 and connected with the air bag ring 3. The wide band 4 is an elastic band.

Wherein, a pressing piece 5 used for fastening the airbag ring 3 is connected between the baffle 2 and the airbag ring 3, the pressing piece 5 comprises a pressing plate 51 and a rotating shaft 52, the pressing plate 51 is rotatably sleeved on the rotating shaft 52, a threaded hole is arranged on the reverse side of the baffle 2, one end of the rotating shaft 52 is inserted into the threaded hole and is in threaded connection with the threaded hole, and the other end of the rotating shaft 52 is fixedly connected with a handle 53; turning the handle 53, the handle 53 presses the pressing plate 51 toward the airbag case 3.

For the use of this example, reference is made to the following steps:

before using the oropharyngeal tube described above, first, the baffle 2 is snapped into the annular groove 31.
