Detailed Description

The endotracheal tube of the present utility model will be described in more detail below in conjunction with the schematic drawings, in which preferred embodiments of the present utility model are shown, it being understood that one skilled in the art can modify the utility model described herein while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. The advantages and features of the present utility model will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1 to 4, an embodiment of the present utility model proposes an endotracheal tube, which includes a tube body 1, a limit flange 2, a bite block body 3, and an elastic clip 4.

The limiting flange 2 is arranged on the outer wall of the cannula body 1, and two limiting flanges are annularly arranged and used for moving and limiting the bite-block body 3.

Wherein, the surface of the limit flange 2 is provided with a chute 21 and a plurality of arc limit grooves 22 which are mutually communicated.

The bite-block body 3 is detachably mounted on the limit flange 2 through the elastic clamp 4, namely, the bite-block body 3 can be mounted on the limit flange 2 by means of elastic clamping of the elastic clamp 4, so that medical staff can clamp the bite-block body 3 on the limit flange 2 in a single-hand handheld manner to complete connection of the bite-block body 3 and the cannula body 1.

It should be noted that the elastic clip 4 has a connection portion 41 matching with the sliding groove 21 and the arc-shaped limiting groove 22, and the connection portion 41 is disposed at different positions (such as the sliding groove 21 and the arc-shaped limiting groove 22) on the elastic clip 4 to realize sliding or relative fixing of the bite block body 3 and the cannula body 1.

Specifically, when the connecting portion 41 is disposed inside the chute 21, the elastic clip 4 can drive the bite block body 3 to move along the length direction of the cannula body 1. When the connecting part 41 is placed in the arc-shaped limit groove 22, the elastic clamp 4 is kept relatively fixed along the length direction of the cannula body 1. That is, when the dental pad body 3 needs to be mounted at a specific position of the cannula body 1, the connecting portion 41 can slide in the sliding groove 21, and when the dental pad body is mounted at the specific position, the connecting portion 41 is placed in the arc-shaped limiting groove 22, so that the dental pad body 3 cannot move along the length direction of the cannula body 1, and the dental pad body 3 and the cannula body 1 are relatively fixed.

It should be noted that, when the dental pad body 3 is applied, the tongue abutting force (i.e. the force along the length direction of the cannula body 1) of the patient is mainly applied, so that the dislocation is avoided, and the connection stability of the cannula body 1 and the dental pad body 3 is ensured.

The device makes the bite block body 3 and the cannula body 1 block or separate by utilizing the mode of elastic clamping through the limit flange 2 and the elastic clamp 4, thereby achieving the purpose of being convenient for medical staff to install the bite block body 3 on the cannula body 1 by one hand.

Moreover, because the chute 21 and the arc-shaped limit groove 22 are formed in the limit flange 2, and the elastic clamp 4 is provided with the connecting portion 41 matched with the chute 21 and the arc-shaped limit groove 22, the connecting portion 41 can move along the length direction of the cannula body 1 when being arranged in the chute 21, and can be kept fixed along the length direction of the cannula body 1 when being arranged in the arc-shaped limit groove 22, the relative movement or the relative fixation between the bite-block body 3 and the cannula body 1 can be completed according to different position states of the connecting portion 41, so that when the bite-block body 3 is required to be arranged at a specific position of the cannula body 1, a medical staff can push the elastic clamp 4 to move on the limit flange 2 by one hand, and after moving to the specific position, the connecting portion 41 of the elastic clamp 4 is arranged in the arc-shaped limit groove 22, thereby achieving the aim of improving the connection stability of the cannula body 1 and the bite-block body 3, and the aim of avoiding medical care resource waste when the medical staff can operate by one hand in the process can also be achieved.

In this embodiment, the limit flange 2 is configured in an arc structure, that is, the outer wall is configured in an arc shape, so as to be convenient to dock with the elastic clamp 4.

The limiting flange 2 is fixedly connected with the outer wall of the cannula body 1, and the limiting flange 2 and the cannula body 1 can be integrally formed.

Preferably, the inner surface of the elastic clip 4 is arc-shaped, and is attached to the outer surface of the limit flange 2, that is, when the elastic clip 4 is clamped on the limit flange 2, the elastic clip can move or rotate relative to the limit flange 2, so that the connecting portion 41 can rotationally enter the chute 21 or the arc-shaped limit groove 22, and the relative movement or the relative fixation of the bite-block body 3 and the cannula body 1 is realized.

In addition, the elastic clamp 4 is fixedly connected with the bite-block body 3.

In order to facilitate the connection and fixation between the bite block body 3 and the elastic clip 4, the outer side surface of the elastic clip 4 is set to be a flat cut surface. If the flat section is coated with adhesive, the elastic clamp 4 and the tooth cushion body 3 are adhered and fixed together.

In other embodiments, the cushion body 3 and the elastic clip 4 may be integrally formed.

In this embodiment, the plurality of arc-shaped limiting grooves 22 are equidistantly arranged along the length direction of the cannula body 1, and the connection portion 41 is abutted with the arc-shaped limiting grooves 22 at different positions to complete the relative fixation of the bite-block body 3 at different positions and the cannula body 1 in the length direction of the cannula body 1.

Wherein, the bite-block body 3 is provided with a rectangular hollow structure, namely, is used as a deformation cavity for bearing teeth of a patient, and prevents the teeth from being in direct contact with the cannula body 1, so that the cannula body 1 is damaged.

In this embodiment, the elastic clip 4 is made of plastic.

In other embodiments, the arc-shaped limiting groove 22 is perpendicular to the sliding groove 21, so that the bite-block body 3 and the cannula body 1 can be relatively fixed by rotating the elastic clip 4 with one hand by a medical staff.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
