Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a tracheal cannula. Background Art

[0002] Endotracheal tube is the most commonly used medical device in clinical emergency resuscitation, rescue of patients with respiratory arrest, surgical anesthesia and opening of airway. The method of using the endotracheal tube is to insert it into the patient's trachea through the mouth or nose. The safe fixation of the endotracheal tube during use is an important guarantee for the success of the intubation.

[0003] In the prior art, in order to prevent the patient from biting the endotracheal tube, the endotracheal tube is usually used in conjunction with a dental pad. However, the endotracheal tube and the dental pad are currently mostly bonded by adhesive tape. The adhesive tape is affected by saliva or the patient's mouth secretions, which will cause the adhesiveness of the tape to fail, resulting in relative movement and dislocation between the endotracheal tube and the dental pad. The dental pad cannot play the role of supporting the patient's teeth, resulting in damage to the endotracheal tube. In addition, when bonding the dental pad to the endotracheal tube with adhesive tape, the medical staff needs to use both hands to operate. Since the medical staff needs to hold the endotracheal tube with one hand, they need to rely on other medical staff for auxiliary operation, which takes a long time and wastes medical resources.

[0004] Therefore, a tracheal tube is needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an endotracheal cannula, so that medical personnel can complete the connection and relative fixation of the tooth pad body and the cannula body with one hand, and can improve the stability of the connection, reduce the difficulty of installation and avoid the waste of medical resources.

[0006] In order to solve the above technical problems, the utility model provides a tracheal cannula, comprising a cannula body, a limiting flange, a tooth pad body and an elastic clamp;

[0007] The limiting flange is arranged on the outer wall of the insert tube body, and two of them are arranged in an annular shape, and the surface of the limiting flange is provided with mutually communicating sliding grooves and a plurality of arc-shaped limiting grooves;

[0008] The tooth pad body is detachably mounted on the limiting flange via the elastic clamp;

[0009] The elastic clamp has a connecting portion matching the slide groove and the arc-shaped limiting groove;

[0010] When the connecting portion is placed inside the slide groove, the elastic clamp can drive the bite block body to move along the length direction of the cannula body;

[0011] When the connecting portion is placed inside the arc-shaped limiting groove, the elastic clamp is kept relatively fixed along the length direction of the cannula body.

[0012] Furthermore, the limiting flange is configured as an arc-shaped structure.

[0013] Furthermore, the inner surface of the elastic clamp is configured to be arc-shaped and fits with the outer surface of the limiting flange.

[0014] Furthermore, the limiting flange is fixedly connected to the outer wall of the cannula body.

[0015] Furthermore, the elastic clamp is fixedly connected to the bite block body.

[0016] Furthermore, the outer side surface of the elastic clamp is configured as a flat section.

[0017] Furthermore, the plurality of arc-shaped limiting grooves are arranged at equal intervals along the length direction of the cannula body.

[0018] Furthermore, the tooth pad body is configured as a rectangular hollow structure.

[0019] Furthermore, the elastic clamp is made of plastic material.

[0020] Furthermore, the arc-shaped limiting groove and the sliding groove are arranged perpendicularly.

[0021] Compared with the prior art, the utility model has at least the following beneficial effects:

[0022] By providing a limiting flange and an elastic clamp, the bite block body and the cannula body are engaged or separated by elastic engagement, so that medical personnel can easily install the bite block body on the cannula body with one hand.

[0023] Furthermore, since the limiting flange has a sliding groove and an arc-shaped limiting groove and the elastic clamp has a connecting portion that matches the sliding groove and the arc-shaped limiting groove, and the connecting portion can move along the length direction of the cannula body when placed inside the sliding groove, and remain fixed along the length direction of the cannula body when placed inside the arc-shaped limiting groove, the relative movement or relative fixation between the tooth pad body and the cannula body can be completed according to the different position states of the connecting portion. Therefore, when the tooth pad body needs to be installed at a specific position of the cannula body, the medical staff can push the elastic clamp to move on the limiting flange with one hand, and when it moves to the specific position, the connecting portion of the elastic clamp is placed in the arc-shaped limiting groove to complete the limiting of the tooth pad body, thereby achieving the purpose of improving the connection stability between the cannula body and the tooth pad body. Since the medical staff can operate the above process with one hand, it can also achieve the purpose of reducing the difficulty of installation while avoiding the waste of medical resources.

[0029] The endotracheal tube of the present invention will be described in more detail below in conjunction with a schematic diagram, wherein a preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the present invention.

[0030] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0031] like Figures 1 to 4 As shown, an embodiment of the utility model provides an endotracheal cannula, comprising a cannula body 1, a limiting flange 2, a tooth pad body 3 and an elastic clamp 4.

[0032] The limiting flange 2 is arranged on the outer wall of the insert body 1 , and two of them are arranged in a ring shape, and are used for the movement and limiting of the bite block body 3 .

[0033] The surface of the limiting flange 2 is provided with a sliding groove 21 and a plurality of arc-shaped limiting grooves 22 which are interconnected.

[0034] The bite pad body 3 is detachably mounted on the limiting flange 2 via the elastic clamp 4, that is, the bite pad body 3 can be mounted on the limiting flange 2 with the aid of the elastic clamp 4, so the medical staff can clamp the bite pad body 3 on the limiting flange 2 by holding it with one hand to complete the connection between the bite pad body 3 and the cannula body 1.

[0035] It should be particularly noted that the elastic clamp 4 has a connecting portion 41 that matches the slide groove 21 and the arc-shaped limit groove 22. The sliding or relative fixation of the tooth pad body 3 and the cannula body 1 is achieved by placing the connecting portion 41 at different positions on the elastic clamp 4 (such as the slide groove 21 and the arc-shaped limit groove 22).

[0036] Specifically, when the connection part 41 is placed inside the slide groove 21, the elastic clamp 4 can drive the tooth pad body 3 to move along the length direction of the cannula body 1. When the connection part 41 is placed inside 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 tooth pad body 3 needs to be installed at a specific position of the cannula body 1, the connection part 41 can be slid in the slide groove 21, and when it reaches the specific position, the connection part 41 is then placed inside the arc-shaped limit groove 22, so that the tooth pad body 3 cannot move along the length direction of the cannula body 1, thereby completing the relative fixation of the tooth pad body 3 and the cannula body 1.

[0037] It should be noted that the bite block body 3 is usually mainly subjected to the abutment force of the patient's tongue (i.e., the force along the length direction of the cannula body 1) when in use, so there will be no misalignment, ensuring the stability of the connection between the cannula body 1 and the bite block body 3.

[0038] The device uses the limiting flange 2 and the elastic clamp 4 to elastically engage or separate the bite block body 3 and the cannula body 1, so that the medical staff can easily install the bite block body 3 on the cannula body 1 with one hand.

[0039] Furthermore, since the limiting flange 2 has a slide groove 21 and an arc-shaped limiting groove 22 and the elastic clamp 4 has a connecting portion 41 that matches the slide groove 21 and the arc-shaped limiting groove 22, and the connecting portion 41 can be moved along the length direction of the cannula body 1 when placed inside the slide groove 21, and remains fixed along the length direction of the cannula body 1 when placed inside the arc-shaped limiting groove 22, the relative movement or relative fixation between the tooth pad body 3 and the cannula body 1 can be completed according to the different position states of the connecting portion 41. Therefore, when the tooth pad body 3 needs to be installed at a specific position of the cannula body 1, the medical staff can push the elastic clamp 4 to move on the limiting flange 2 by one hand, and when it moves to the specific position, the connecting portion 41 of the elastic clamp 4 is placed in the arc-shaped limiting groove 22 to complete the limiting of the tooth pad body 3, thereby achieving the purpose of improving the connection stability between the cannula body 1 and the tooth pad body 3. Since the medical staff can operate the above process with one hand, it can also achieve the purpose of reducing the difficulty of installation and avoiding the waste of medical resources.

[0040] In this embodiment, the limiting flange 2 is configured as an arc-shaped structure, that is, the outer wall is configured as an arc-shaped structure, which is convenient for docking with the elastic clamp 4.

[0041] The limiting flange 2 is fixedly connected to the outer wall of the cannula body 1 , and the limiting flange 2 and the cannula body 1 can be arranged as an integrally formed arrangement.

[0042] Preferably, the inner surface of the elastic clamp 4 is arranged to be arc-shaped and fits with the outer surface of the limiting flange 2, that is, when the elastic clamp 4 is engaged on the limiting flange 2, it can move or rotate relative to the limiting flange 2, so that the connecting part 41 can rotate into the sliding groove 21 or the arc-shaped limiting groove 22, thereby realizing the relative movement or relative fixation of the tooth pad body 3 and the cannula body 1.

[0043] In addition, the elastic clamp 4 is fixedly connected to the bite block body 3 .

[0044] In order to facilitate the connection and fixation between the tooth pad body 3 and the elastic clamp 4, the outer side surface of the elastic clamp 4 is set as a flat cut surface. For example, adhesive is applied on the flat cut surface to bond the elastic clamp 4 and the tooth pad body 3 together.

[0045] In other embodiments, the tooth pad body 3 and the elastic clamp 4 may also be configured as an integrally formed configuration.

[0046] In this embodiment, the plurality of arc-shaped limit grooves 22 are equidistantly arranged along the length direction of the cannula body 1, and the relative fixation of the bite block body 3 and the cannula body 1 in the length direction of the cannula body 1 at different positions is completed by docking the connecting portion 41 with the arc-shaped limit grooves 22 at different positions.

[0047] The tooth pad body 3 is configured as a rectangular hollow structure, that is, it is used as a deformation cavity to support the patient's teeth, thereby preventing the teeth from directly contacting the cannula body 1 and causing damage to the cannula body 1.

[0048] In this embodiment, the elastic clamp 4 is made of plastic.

[0049] In other embodiments, the arc-shaped limiting groove 22 is vertically arranged to the sliding groove 21, so that the relative fixation of the bite block body 3 and the cannula body 1 can be completed by the medical staff rotating the elastic clamp 4 with one hand.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
