Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and more specifically, it relates to a disposable double-lumen endotracheal tube. Background Technology

[0002] Double-lumen endotracheal intubation is mainly used to separate the ventilation of both lungs, preventing secretions from the affected lung from entering the healthy lung; it can also facilitate single-lung ventilation and provide a good field of vision for thoracic surgery.

[0003] Currently, after inserting a endotracheal tube into a patient's bronchus, the tube is typically secured by wrapping it with tape and then attaching the tape to the patient's face. However, this method requires removing the tape from the patient's face during extubation, and prolonged adhesion of the tape can easily cause pain or injury to the face. Therefore, this study aims to improve upon the existing structure and address its shortcomings by providing a disposable double-lumen endotracheal tube with greater practical value.

[0005] A disposable double-lumen endotracheal tube includes a tube body, a connecting frame mounted on one side of the tube body, and a fixing mechanism fixedly connected to the connecting frame; the fixing mechanism includes a first strap and a second strap, one end of the first strap and the second strap are respectively fixedly connected to one end of the connecting frame, one end of the second strap is fixedly connected to a loop, one end of the first strap passes through the loop and is fixedly connected to a Velcro first, and one side of the first strap is fixedly connected to a Velcro second that can be mutually attached to the Velcro first.

[0006] Furthermore, the inner side of the connecting frame is provided with a sliding groove, and a connecting block is slidably connected to the inner side of the sliding groove. Damping plates are fixedly installed on the contact surface of the connecting block near the sliding groove.

[0007] Furthermore, a mounting base is fixedly installed on one side of the connecting block, and an elastic tube for connecting the cannula body is fixedly installed on one side of the mounting base.

[0008] Furthermore, one end of the connecting block passes through the slide groove and is fixedly installed with a limiting seat.

[0009] Furthermore, a protective pad, made of silicone material, is fixedly adhered to the bottom side of the connecting frame.

[0010] Furthermore, an adhesive tape is fixedly connected to one side of the mounting base, and one side of the adhesive tape is sticky and connected to release paper.

[0011] Furthermore, both the first and second straps are provided with multiple sets of ventilation holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the cooperation of the fixing mechanism and the connecting frame, can stably fix the connecting frame to the patient's face. Through the cooperation of the connecting frame, the connecting block and the mounting base, the cannula body and the connecting frame can be connected conveniently and stably. Through the cooperation of the tape and the cannula body, the stability of the cannula during fixation can be increased, thereby avoiding the need to use tape to fix the cannula to the patient's face and avoiding damage to the patient's face when the tape is removed.

[0014] 2. This utility model, through the cooperation of the connecting frame and the connecting block, enables the connecting block to move flexibly within the connecting frame, and drives the flexible movement of the intubation body, which facilitates medical staff to perform oral care on patients using the intubation body, thus increasing the practicality of the product.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a disposable double-lumen endotracheal tube, including a tube body 1. A connecting frame 2 is installed on one side of the tube body 1, and a fixing mechanism is fixedly connected to the connecting frame 2. The fixing mechanism includes a first strap 601 and a second strap 602. One end of the first strap 601 and the second strap 602 are respectively fixedly connected to one end of the connecting frame 2. One end of the second strap 602 is fixedly connected to a loop 603. One end of the first strap 601 passes through the loop 603 and is fixedly connected to a first Velcro 604. A second Velcro 605 that can be fitted to the first Velcro 604 is fixedly connected to one side of the first strap 601.

[0027] The connecting frame 2 has a sliding groove on its inner side, and a connecting block 3 is slidably connected to the inner side of the sliding groove. Each connecting block 3 has a damping plate fixedly installed on its contact surface with the sliding groove, which can realize the flexible movement of the connecting block 3 within the connecting frame 2 and drive the flexible movement of the intubation body 1. This facilitates medical staff to clean the inside of the patient's mouth when using the intubation body 1, and prevents the intubation body 1 from being fixed and leaving dead corners in the patient's mouth that cannot be cleaned.

[0028] The connecting block 3 has a mounting base 4 fixedly installed on one side, and an elastic tube 5 for connecting the cannula body 1 is fixedly installed on one side of the mounting base 4, so as to facilitate the connection between the cannula body 1 and the connecting block 3.

[0029] One end of the connecting block 3 passes through the slide groove and is fixedly installed with the limiting seat 9 to prevent the connecting block 3 from falling out of the slide groove.

[0030] A protective pad 8, made of silicone, is fixedly adhered to the bottom side of the connecting frame 2 to prevent the connecting frame 2 from causing damage to the patient's face.

[0031] The mounting base 4 has an adhesive tape 7 fixedly connected to one side, which can enhance the stability of the insertion tube body 1 when it is fixed. One side of the adhesive tape 7 is sticky and has release paper attached to it to prevent the adhesive tape 7 from getting dusty and losing its stickiness when it is not in use.

[0032] Both the first strap 601 and the second strap 602 are provided with multiple sets of ventilation holes to increase the patient's comfort when wearing the fixation device.

[0033] The working principle of this embodiment is as follows: When the intubation body 1 is needed, the intubation tube is first inserted into the patient's body. Then, the first strap 601 is wrapped around the back of the patient's head and passed back to the ring buckle 603. The connecting frame 2 is placed at the philtrum of the patient. The intubation body 1 is connected to the elastic tube 5. The first strap 601 is then passed through the ring buckle 603. The first Velcro 604 and the second Velcro 605 are connected to complete the fixation of the connecting frame 2. The release paper on the tape 7 is peeled off. The tape 7 is wrapped around the intubation body 1 and bonded to the intubation body 1. One end of the tape 7 is bonded to the mounting base 4 to complete the fixation of the intubation body 1.

[0034] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
