Description

Technical Field

[0001] The utility model belongs to the field of medical devices, and particularly relates to a multifunctional tracheal intubation tube. Background Technique

[0002] Tracheal intubation is a method of inserting a special endotracheal tube through the oral cavity or nasal cavity and into the trachea or bronchus through the glottis, providing the best conditions for airway patency, ventilation and oxygen supply, airway suction, etc. It is widely used in the fields of clinical anesthesia, emergencies, intensive care treatment, etc., and is also an important measure for rescuing patients with respiratory dysfunction.

[0003] At present, the tracheal intubation tubes used clinically have a simple structure and single function. First, in clinical surgical anesthesia, anesthesiologists usually need to perform topical anesthesia on the epiglottis and glottis of the patient before tracheal intubation to reduce the adverse stimulation brought by tracheal intubation to the patient. At present, topical anesthesia needs to be operated with a separate nebulizer or catheter, which increases the operation procedure and the medical burden of the patient. Secondly, a separate bite block needs to be placed after tracheal intubation to prevent the patient from having unexpected bites during anesthesia, especially during the awakening period. In addition, when a patient uses a tracheal intubation tube, especially in the intensive care field, the tracheal intubation tube needs to be retained for a long time. During this period, a large amount of secretions will accumulate in the trachea, around the trachea and in the oral cavity. These secretions need to be processed in time, otherwise it will cause or exacerbate oral and pulmonary infections, and even block the airway. In the existing technology, the secretions in the trachea and oral cavity can be aspirated repeatedly through a suction catheter, but it cannot meet the aspiration of the secretions near the oral end above the tracheal tube balloon, and it is extremely easy to form sputum crusts, which are very likely to block the airway during the process of removing the tracheal tube, resulting in asphyxia after extubation. Content of the Utility Model

[0004] In view of this, the utility model aims to provide a multifunctional tracheal intubation tube, which simultaneously has the functions of topical anesthesia of the epiglottis and glottis before tracheal intubation, tracheal drug administration, anti-bite, and aspiration above the balloon and above the oral cavity and glottis.

[0005] To achieve the above object, the technical solution of the utility model is realized as follows:

[0006] A multifunctional endotracheal tube, comprising a tube body, an airbag, and a bite block. The airbag is arranged at one end of the tube body inserted into the trachea. The bite block is sleeved on the tube body and can slide along the tube body. The tube body is provided with a medicine injection hole and a suction hole. A plurality of medicine injection holes are evenly arranged on the end face of the tube body near the airbag end. The tube body is provided with an air injection tube, a medicine injection tube, and a suction tube.

The medicine injection tube is communicated with the medicine injection hole, and the end of the medicine injection tube is connected with a medicine injection joint. Anesthetic drugs are injected through the medicine injection tube to perform surface anesthesia on the patient's epiglottis and glottis. The suction tube is communicated with the suction hole, and the end of the suction tube is connected with a suction joint to suck out secretions in time to prevent infection.

[0007] Further, a conical platform is arranged on the tube body. The conical platform can be connected with the bite block in an interference fit manner to fix the bite block. When in use, the bite block can be pulled out from the conical platform.

[0008] Further, a medicine injection sandwich layer is arranged in the tube wall of the tube body between the airbag and the medicine injection hole. The medicine injection hole and the medicine injection tube are both communicated with the medicine injection sandwich layer. After the anesthetic drugs enter the medicine injection sandwich layer, they are evenly ejected through a plurality of medicine injection holes to achieve uniform drug administration and ensure the anesthetic effect.

[0009] Further, a scale is arranged on the tube body to visually control the insertion depth of the intubation.

[0010] Further, a gasket is arranged on the bite block to prevent the patient from accidentally swallowing the bite block into the mouth.

[0011] Further, hanging ears are arranged on the bite block for installing a hanging rope to assist in fixing the bite block.

[0012] Further, the bite block is made of polyethylene material.

[0013] Further, one end of the tube body near the airbag is a bevel surface, and the opening direction of the medicine injection hole faces the human tissue, spraying the medicine onto the surface of the human tissue for anesthesia or drug administration.

[0014] Further, a swivel joint is arranged at one end of the tube body away from the airbag, and the tube body is connected to a ventilator through the swivel joint.

[0015] Further, the tube body is one or a plurality of arranged in parallel. When there are a plurality of tube bodies, the adjacent two tube bodies can be adhesively bonded or integrally injection molded. The airbag and the bite block are sleeved on all the tube bodies, and each tube body is connected with a swivel joint.

[0016] Further, a guide wire is inserted into the tube body to assist in completing the intubation.
