Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a visual endotracheal intubation laryngoscope. Background Technology

[0002] Currently, when performing endotracheal intubation on patients, it is necessary to first use a laryngoscope to open the epiglottis to expose the glottis, so that the endotracheal tube can be directly inserted into the glottis.

[0003] In existing technologies, laryngoscopes can only provide convenient conditions for exposing the patient's glottis. However, during endotracheal intubation, due to the difficulty of the procedure, there are still situations where tube placement is difficult or damage to the pharynx can occur. In other words, the accuracy of endotracheal intubation needs to be improved. Therefore, there are still shortcomings and deficiencies in existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a visual endotracheal intubation laryngoscope to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A visual endotracheal intubation laryngoscope includes a laryngoscope body, which includes a laryngoscope handle and a laryngoscope blade connected together. The laryngoscope blade is an inwardly concave arc-shaped blade. A camera is installed at the end of the laryngoscope blade away from the laryngoscope handle. The camera is electrically connected to a data cable. The end of the data cable away from the camera passes through the laryngoscope blade and the laryngoscope handle in sequence and is electrically connected to a data interface located outside the laryngoscope handle. An endotracheal tube channel is formed on the laryngoscope handle along its length.

[0007] Furthermore, the laryngoscope handle includes a straight portion and an inwardly concave arc-shaped portion. Both the arc-shaped portion and the straight portion are tubular structures with openings at both ends. One end of the arc-shaped portion is fixedly connected to the straight portion, and the other end of the arc-shaped portion is fixedly connected to the laryngoscope blade. The arc angle of the arc-shaped portion is 70 degrees to 90 degrees.

[0008] Furthermore, one side of the laryngoscope handle has a notch that communicates with the tracheal tube channel along the length of the laryngoscope handle. The notch is the same length as the tracheal tube channel, and a movable plate that is adapted to the notch is slidably connected inside the notch.

[0009] Furthermore, guide grooves are provided on the laryngoscope handles on both sides of the notch along the length of the notch. The end of the guide groove near the laryngoscope blade is closed. Guide blocks that are compatible with the guide grooves are fixedly connected to both sides of the movable plate.

[0010] Furthermore, both the laryngoscope handle and the laryngoscope blade are made of plastic.

[0011] Furthermore, the data interface is a TPC interface.

[0012] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] In use, this invention allows the laryngoscope body to be fully inserted into the patient's mouth, starting from the end of the laryngoscope blade furthest from the handle, to open the epiglottis and expose the glottis. A tracheal tube channel is created on the laryngoscope handle, allowing the tracheal tube to be inserted into the channel during intubation. The tracheal tube channel guides the tracheal tube for easier insertion. Furthermore, by incorporating a camera, data cable, and data interface, an external video monitor or mobile phone can be connected to directly display the glottis position, facilitating observation of the tracheal tube insertion. This reduces the difficulty of intubation, improves the accuracy of tracheal intubation, and increases the success rate of intubation in difficult airways. Attached Figure Description

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 3As shown, this utility model provides a visual endotracheal intubation laryngoscope, including a laryngoscope body, which includes a laryngoscope handle 2 and a laryngoscope blade 1 connected together. The laryngoscope blade 1 is an inwardly concave arc-shaped blade. A camera 3 is installed at the end of the laryngoscope blade 1 away from the laryngoscope handle 2. A data cable 4 is electrically connected to the camera 3. The end of the data cable 4 away from the camera 3 passes through the laryngoscope blade 1 and the laryngoscope handle 2 in sequence and is electrically connected to a data interface 5 located outside the laryngoscope handle 2. Specifically, the data interface 5 is a TPC interface. In use, a video monitor or mobile phone or other device can be connected through the data interface 5. In addition, before inserting the laryngoscope body into the patient's mouth, the lens of the camera 3 can be slightly heated with the help of an external device. This can prevent fogging on the lens of the camera 3 when the laryngoscope body is in the patient's mouth. An endotracheal tube channel 21 is opened along the length direction of the laryngoscope handle 2, which is compatible with the endotracheal tube used for endotracheal intubation.

[0020] Specifically, during use, the laryngoscope body can be fully inserted into the patient's mouth from the end of the laryngoscope blade 1 furthest from the handle 2 to open the epiglottis and expose the glottis. By creating an endotracheal tube channel 21 on the laryngoscope handle 2, the endotracheal tube can be inserted into the endotracheal tube channel 21 during endotracheal intubation. At this time, the endotracheal tube channel 21 can guide the endotracheal tube to facilitate intubation. Furthermore, by setting up a camera 3, a data cable 4, and a data interface 5, an external video monitor or mobile phone can be connected to directly display the position of the glottis, so as to observe the specific situation when the endotracheal tube is inserted into the glottis. This can reduce the difficulty of endotracheal intubation, improve the accuracy of endotracheal intubation, and increase the success rate of intubation in difficult airways. Then, when the intubation is successful, the laryngoscope body is removed from the patient's mouth, and the endotracheal tube is fixed after the laryngoscope body is withdrawn.

[0021] Furthermore, such as Figure 1 As shown, the laryngoscope handle 2 includes a straight portion 22 and an inwardly concave arc-shaped portion 23. Both the arc-shaped portion 23 and the straight portion 22 are tubular structures with openings at both ends. One end of the arc-shaped portion 23 is fixedly connected to the straight portion 22, and the other end of the arc-shaped portion 23 is fixedly connected to the laryngoscope blade 1. Specifically, the laryngoscope blade 1 is located outside the opening of the arc-shaped portion 23 and does not affect the passage of the endotracheal tube through the endotracheal tube channel 21. In addition, the arc angle of the arc-shaped portion 23 is 70 to 90 degrees, which allows the laryngoscope body to better fit the shape and structure of the patient's pharynx. Thus, when the laryngoscope body is fully inserted into the patient's oral cavity, the epiglottis can be opened and the glottis exposed. When the glottis is not fully exposed, since the laryngoscope body is completely located in the patient's oral cavity, the laryngoscope handle 2 can be used to press down the laryngoscope body to fully expose the glottis. Furthermore, the size of the laryngoscope body can be set according to actual conditions, for example: Figure 1For example, when the laryngoscope body is in a vertical position, the overall length of the laryngoscope body in the vertical direction can be set to 10-12cm, and the overall length in the horizontal direction can be set to 8-10cm. This conforms to the size of the adult oral cavity, so that the laryngoscope body can be fully inserted into the patient's oral cavity.

[0022] Furthermore, such as Figure 2 and Figure 3 As shown, a notch 24 communicating with the endotracheal tube channel 21 is provided on one side of the laryngoscope handle 2 along the length of the laryngoscope handle 2. The notch 24 is the same length as the endotracheal tube channel 21, and a movable plate 25 adapted to the notch 24 is slidably connected inside the notch 24, that is, the movable plate 25 is detachable. Specifically, in use, before removing the laryngoscope body from the patient's mouth, the movable plate 25 can be removed, and then the endotracheal tube can be completely moved out of the laryngoscope body through the notch 24. This can avoid the endotracheal tube affecting the movement of the laryngoscope body, so as to facilitate the removal of the laryngoscope body from the patient's mouth.

[0023] The specific setup for the sliding connection between the movable plate 25 and the notch 24 is as follows: Figure 2 and Figure 3 As shown, guide grooves 26 are provided on the laryngoscope handle 2 on both sides of the notch 24 along the length of the notch 24. The end of the guide groove 26 near the laryngoscope blade 1 is closed. Guide blocks 27 that are adapted to the guide grooves 26 are fixedly connected to both sides of the movable plate 25. Specifically, the guide blocks 27 can be set to be the same length as the guide grooves 26, or two guide blocks 27 can be set on each side of the movable plate 25, and the two guide blocks 27 are located at both ends of the movable plate 25. In this way, when installing the movable plate 25 on the laryngoscope handle 2, the guide blocks 27 can be inserted into the guide grooves 26 respectively until the guide blocks 27 abut against the closed end of the guide grooves 26, and the movable plate 25 can be installed on the laryngoscope handle 2. When removing the movable plate 25, the movable plate 25 can be pulled out directly, and then the endotracheal tube can be completely removed from the laryngoscope body through the notch 24.

[0024] Furthermore, both the laryngoscope handle 2 and the laryngoscope blade 1 are made of plastic material, specifically, the medical plastic material in the prior art. This allows the movable plate 25 to deform to a certain extent when it is attached or detached from the laryngoscope handle 2, making it easier to attach or detach from the laryngoscope handle 2. In addition, the laryngoscope handle 2 and the laryngoscope blade 1 are an integral structure, which makes them easy to store and carry.

[0025] The specific usage process of this utility model is as follows: First, before use, disinfect the laryngoscope and slightly heat the lens of the camera 3 with the help of an external device, and then connect a video monitor or mobile phone or other device through the data interface 5; Second, insert the laryngoscope body completely into the patient's mouth from the end of the laryngoscope blade 1 away from the handle 2 to open the epiglottis and expose the glottis; Third, insert the endotracheal tube into the endotracheal tube channel 21 for intubation, and the endotracheal tube channel 21 can guide the endotracheal tube to facilitate intubation, and the position of the glottis can be directly displayed through the video monitor or mobile phone or other device to observe the specific situation when the endotracheal tube is inserted into the glottis; Fourth, when the intubation is successful, remove the movable plate 25, and the endotracheal tube can be completely removed from the laryngoscope body through the notch 24, and then remove the laryngoscope body from the patient's mouth, and fix the endotracheal tube after the laryngoscope body is removed.
