CN102580198A - Accurate-positioned double-tube laryngeal mask - Google Patents

Abstract

The invention discloses an accurate-positioned double-tube laryngeal mask, which comprises a cuff, an airway tube, an inflation tube and an indicating balloon, wherein the front end of the cuff is provided with a drainage hole, and the cuff is also connected with an independent drainage tube. The front end of the drainage tube is connected with the drainage hole, and the periphery of the drainage hole is provided with a LED (Light-Emitting Diode) lamp along the circumference of the drainage hole. As the independent drainage tube is arranged, the accurate-positioned double-tube laryngeal mask can carry out manual suction and negative pressure suction for stomach contents. The LED lamp arranged at the front end of the cuff plays an indication role and helps a doctor accurately insert into the laryngo-pharynx part of a patient, the condition of poor air seal due to operation errors is prevented, and the air seal of the laryngo-pharynx part is enhanced.

Description

Dual tube laryngeal mask for precise positioning

technical field

The invention discloses a double-pipe laryngeal mask capable of accurate positioning, which belongs to the field of medical instruments.

Background technique

At present, the LMA laryngeal mask in the hospital is mainly used for artificial ventilation during surgical general anesthesia, first aid and resuscitation; during general anesthesia, the doctor inserts the laryngeal mask into the throat of the patient through the mouth to establish an artificial airway. During the operation of the patient, the effective airway is maintained to ensure a safe and smooth operation process; among them, the LMA-ProSeal gastric tube drainage type laryngeal mask is the third generation laryngeal mask, and the laryngeal mask has double tubes, one tube can be ventilated, and the other tube can be inserted gastric tube drainage.

Its disadvantages are: when the laryngeal mask is inserted into the patient's pharynx, the doctor's precise operation is required to seal the throat. ACCIDENT.

Contents of the invention

The invention intends to provide a double-pipe laryngeal mask which can reduce operation errors and has an indicating function and can be positioned accurately.

The object of the present invention can be achieved through the following measures: a double-tube laryngeal mask that can be positioned accurately, including a cuff, a ventilation catheter, an inflation tube and an indicator balloon, the front end of the cuff has a drainage hole, and the cuff An independent drainage tube is also connected, and the front end of the drainage tube is connected with the drainage hole, and an LED lamp is installed on the periphery of the drainage hole along its circumference.

The difference between the above-mentioned technical solution and the prior art is that the present invention has an independent drainage tube, which can perform manual and negative pressure suction on the contents of the stomach; the LED light at the front end of the cuff has an indication function and helps the doctor to insert the patient accurately The throat and throat can prevent the air tightness caused by operating errors, and strengthen the air tightness of the throat and throat.

Furthermore, because the cuff will be squeezed and deformed during the insertion process, the lead wire of the LED light is set on the wall of the drainage tube, and the battery box is set at the rear end of the drainage tube to ensure stable energy supply of the LED light during insertion.

Further, in order to prevent the bifurcation formed by the ventilation catheter and the drainage tube from tearing the oral cavity of the patient; the ventilation catheter and the drainage tube are connected through a connecting piece.

Furthermore, in order to fit the curve of the patient's throat, the double-tube laryngeal mask is required to have a certain shaping effect. The ventilation catheter and drainage tube in the present invention are all made of shaped flexible tubes.

The invention conforms to the physiological anatomical curve of the human throat and throat, avoids operation accidents caused by human errors, has simple structure and wide application range.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

Fig. 1 is a schematic structural view of an embodiment of a double-tube laryngeal mask that can be positioned accurately in the present invention.

Detailed ways

Referring to Figure 1, a double-tube laryngeal mask that can be accurately positioned includes a cuff 1, a ventilation catheter 2, a drainage tube 3, an inflatable tube 4, and an indicator balloon 5. The shape of the cuff 1 is pointed at the front and round at the back. The cover body, the edge of the cover body is an inflatable protrusion, which is connected with the inflation tube 4 and the indicator balloon 5; the front end of the cuff 1 has a drainage hole 11, and the rear end of the cuff 1 is respectively connected with a ventilation catheter 2 and the drainage tube 3, the front end of the drainage tube 3 is connected with the drainage hole 11, and the periphery of the drainage hole 11 is equipped with an LED light 6 along its circumference, and the wire of the LED light 6 is arranged on the wall of the drainage tube 3, and the battery box It is arranged at the rear end of the drainage tube 3; the ventilation duct 2 and the drainage tube 3 are connected together through a connecting piece 7; wherein, the ventilation duct 2 and the drainage tube 3 are both shapeable metal hoses.

When in use, the doctor inserts the double-tube laryngeal mask from the patient's mouth into the hypopharynx. The front end of the cuff 1 is in contact with the patient's upper esophageal sphincter, and the rear end is in contact with the lower part of the tongue base. 2 communicate with each other to form effective ventilation; the doctor inserts the gastric juice intubation tube from the drainage tube 3, enters the esophagus from the front end of the cuff 1, and then performs the gastric juice drainage operation.

The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the present invention. The scope of protection, these will not affect the effect of the implementation of the present invention and the practicability of the patent.
