Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a visible laryngeal anesthesia tube for awake tracheal intubation. Background Art

[0002] Difficult airway, as a common problem in anesthesia management, is a difficult problem that every anesthesiologist will face and must solve during their career.

[0003] Regarding the management of difficult airway, especially during anesthesia, the surface anesthesia device for awake tracheal intubation aims to fully anesthetize, clearly locate the local anesthetic site of the patient, guide the anesthesiologist to effectively deal with the difficult airway, continuously improve the success rate of the first attempt of tracheal intubation, ensure the safety of the patient during airway operation, and reduce or avoid adverse events caused by difficult airway and airway operation.

[0004] Airway difficulty is relatively common in patients undergoing oral and maxillofacial surgery. The factors causing airway difficulty generally include airway anatomical and physiological variations, local or systemic diseases, and anatomical structure deformities caused by trauma. It is expected that awake intubation should be considered for patients with airway difficulty. For patients who are uncooperative or have intracranial hypertension, coronary heart disease, or asthma at the same time, the risk of intubation difficulty and awake intubation should be weighed, and sufficient topical anesthesia of the nasopharynx, oropharynx, and larynx should be given to the patient after comprehensive consideration.

[0005] Currently, the devices for topical anesthesia can only rely on the personal skills of the anesthesiologist and the preliminary examination of the patient's airway, and it is difficult to grasp the real-time changes of the trachea during intubation. At the same time, the environmental conditions of the topical anesthesia device are not clear, which is likely to cause additional damage to the trachea and increase the surgical risk. Therefore, it is necessary to further propose a new type of topical anesthesia device for awake tracheal intubation, so that the anesthesiologist can also conveniently observe the tracheal intubation process in real time for timely adjustment. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a visible laryngeal anesthesia tube for awake tracheal intubation to solve at least one of the above problems, so as to solve the problem that the internal situation of the trachea cannot be observed in time during tracheal intubation in the prior art. This solution realizes the visualization of the tracheal intubation process and improves the intubation accuracy and success rate.

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 It is an exploded view of the structure of the visual laryngeal anesthesia tube;

[0023] In the figure: 1 - surface anesthesia device; 2 - visual device. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Embodiment 1

[0026] A visible laryngeal anesthesia tube for awake tracheal intubation, as Figure 1 shown, includes a surface anesthesia device 1 and a visible device 2;

[0027] The visible device 2 is arranged side by side with the surface anesthesia device 1, and the visible device 2 is connected to the side of the surface anesthesia device 1;

[0028] The end of the visible device 2 is arranged in the same direction as the end of the surface anesthesia device 1, and the end of the visible device 2 does not exceed the end of the surface anesthesia device 1.

[0029] More specifically, in this embodiment:

[0030] As Figure 1 shown, the surface anesthesia device 1 is a syringe, and a connector is arranged on the syringe needle tube and is connected to the visible device 2; the visible device 2 is composed of a camera at the front end, a transmission module at the end, and a data cable connecting the camera and the transmission module.

[0031] The connector is a parallel sleeve. One side sleeve is sleeved on the needle tube of the surface anesthesia device 1, and the other side sleeve is sleeved on the outside of the visible device 2, so that the surface anesthesia device 1 and the visible device 2 are arranged side by side. In some other embodiments, the connector can also adopt an adhesive tape, and the two are arranged side by side in an adhesive form. The connector can be provided with several at intervals along the length direction of the needle tube as required, so that the surface anesthesia device 1 and the visible device 2 can be firmly connected under a certain length, avoiding falling off during the anesthesia process or being separated in different directions due to obstruction.

[0032] The transmission module of the visible device 2 can adopt a transmission connector, such as a universal connector like a USB connector or a Type-C connector. In addition, the transmission module can also adopt a wireless transmission module, such as a Wifi module, a Bluetooth module, etc.; furthermore, it can be connected to an external data processing device through this transmission module.

[0033] The outside of the data cable of the visible device 2 can be further sleeved with a relatively thicker flexible guiding tube, and the flexible guiding tube is connected to the surface anesthesia device 1 by a connector. The setting of the flexible guiding tube can have a certain strength and also have flexibility, avoiding the data cable being too soft and moving or knotting uncontrollably during tracheal intubation.

[0034] A protective cover can also be sleeved on the front end of the surface anesthesia device 1 (put on when not in use to avoid end contamination).

[0035] In this solution, it is also adopted that the position of the camera at the front end of the visible device 2 does not exceed the front end of the surface anesthesia device 1, so that the visible device 2 does not affect the normal operation of the surface anesthesia device 1 during anesthesia operation.

[0036] The above description of the embodiments is provided to enable those of ordinary skill in the art to understand and use the utility model. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative efforts. Therefore, the utility model is not limited to the above embodiments, and all improvements and modifications made by those skilled in the art without departing from the scope of the utility model according to the disclosure of the utility model should be within the protection scope of the utility model.
