CN205598376U - Can insert endotracheal tube of laryngeal mask of endoscope - Google Patents

Abstract

A laryngeal mask endotracheal catheter capable of inserting an endoscope includes a main pipe, which is provided with an air-filled cavity, a ventilation cavity and an endoscope channel cavity, and several ventilation holes are opened on the ventilation cavity. The utility model is a laryngeal mask tracheal tube that can be inserted into an endoscope, which is suitable for different individuals and prevents the outlet of an air outlet channel from being blocked.

Description

endoscopic laryngeal mask endotracheal tube

technical field

The utility model relates to a medical device for establishing an artificial gas channel for a patient, which is used in surgical anesthesia, rescue of critically ill patients, or other assisted breathing, in particular to a trachea tube on a laryngeal mask that can be inserted into an endoscope.

Background technique

In the process of using the laryngeal mask for surgery, it is sometimes necessary to insert an endoscope into the patient's body for observation or auxiliary surgery. For this reason, a special channel is required on the laryngeal mask to insert the endoscope; There is no special endoscopic channel for ventilation, so patients who need endoscopic surgery cannot use ordinary laryngeal masks for surgery, and need to ventilate through tracheal intubation or insert an endoscope through an incision, which brings great harm to the patient. Injury and pain; in order to improve the above situation, a laryngeal mask that can be inserted into the endoscope is used to seal the esophagus and throat. There is only one outlet of the cavity, but there are individual differences in the epiglottis of patients. In some patients, the hypertrophy of the epiglottis will block the air outlet, which will eventually lead to poor ventilation or insufficient ventilation, which will affect the ventilation effect.

Utility model content

The purpose of the utility model is to provide a laryngeal mask endotracheal tube that can be inserted into the endoscope, which is suitable for different individuals and prevents the outlet of the air outlet channel from being blocked.

In order to achieve the above object, the technical solution of the utility model is: a laryngeal mask endotracheal catheter that can be inserted into an endoscope, including a main pipe, which is provided with an inflatable cavity, a ventilation cavity and an endoscope channel cavity, and the ventilation cavity There are several ventilation holes on it.

The utility model is a laryngeal mask endotracheal catheter that can be inserted into an endoscope, wherein two sealing bags are arranged outside the main tube in turn, the two sealing bags are spaced apart from each other, the sealing bag near the end of the main tube is a small sealing bag, and the other The sealing bag is a large sealing bag, and the two sealing bags are in communication with the inflatable cavity.

The utility model is a laryngeal mask endotracheal tube that can be inserted into an endoscope, wherein there are three ventilation holes, including a large hole at the end of the ventilation cavity and two small holes on the side wall of the ventilation cavity near the end. hole.

After adopting the above scheme, compared with the prior art, there are several ventilation holes on the ventilation cavity of the laryngeal mask endotracheal tube of the utility model that can be inserted into the endoscope, so even if the patient's epiglottis hypertrophy blocks one ventilation hole, there are other ventilation holes. Stomatal ventilation can avoid poor ventilation or insufficient ventilation due to individual patient differences.

detailed description

As shown in Figure 1, the laryngeal mask endotracheal catheter of the utility model that can insert endoscope comprises main pipe 11, is provided with inflatable chamber 10, ventilation chamber 12 and endoscope channel chamber 13 in the main pipe 11, and there are many openings on the ventilation chamber 12. A ventilation hole, the first sealing bag 14 and the second sealing bag 15 are arranged in sequence outside the main pipe 11, the second sealing bag 15 is near the end of the main pipe and the second sealing bag 15 is a small capsule body, and the first sealing bag 14 is a large bag body, the first and second sealed bags are all in communication with the inflatable chamber 10, and the first and second sealed bags 14, 15 are inflated through the inflated chamber 10, and the first sealed bag 14 and the second sealed bag 15 are used to seal the throat and food respectively. At the crossing, the two sealing bags are adapted to the size of the throat and esophagus respectively, so that the sealing effect is better; in this embodiment, there are three ventilation holes, including the large hole 121 opened at the end of the ventilation cavity 12 and the opening near the ventilation cavity 12. The two small holes 122 on the side wall of the end and the three air holes 121 , 122 all penetrate the pipe wall of the main pipe 11 .

During the operation, when using the laryngeal mask with the laryngeal mask endotracheal tube of the utility model that can be inserted into the endoscope, the endoscope is put into the patient's body through the endoscope passage cavity 13, and the ventilation cavity 12 passes through a plurality of ventilation holes The patient's airway is connected, even if the patient's epiglottis hypertrophy blocks one vent hole, there are other vent holes for ventilation, which can avoid poor ventilation or insufficient ventilation due to individual differences in patients.

The above-mentioned embodiments only describe the preferred implementation of the utility model, and do not limit the scope of the utility model. Various modifications and improvements made should fall within the scope of protection determined by the claims of the present utility model.
