Description

Laryngeal mask of injection type

Technical Field

The utility model relates to the field of medical equipment, in particular to laryngeal mask of injection type.

Background

A laryngeal mask is a device for supraglottic ventilation that can be used to maintain the breathing of an unconscious patient, such as a general anaesthetic patient, and to establish a breathing passage for the patient, but has certain disadvantages and is also prone to induce laryngeal spasm due to its particular placement. The laryngeal mask is an supraglottic ventilation device and is placed at the throat part, so that in a shallow anesthesia state, the pressure of the laryngeal mask and the stimulation of surrounding secretions can induce laryngeal spasm and tracheal spasm to cause ventilation obstacle, so that the hot spot problem concerned by anesthesia department doctors is how to relieve the laryngeal spasm and tracheal spasm induced by the laryngeal mask.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: provides a medicine injection type laryngeal mask which can be used for medicine administration at any time.

As a further improvement of the scheme, the port of the breather pipe connected with the cover body is arranged in an inclined mode.

As a further improvement of the scheme, the vent pipe is arranged in an arc-shaped bent mode.

As a further improvement of the scheme, one end of the inflation tube, which is far away from the inflation bag, is provided with a one-way inflation valve.

As a further improvement of the scheme, one end of the medicine injection tube, which is far away from the medicine injection sac, is provided with a medicine injection valve.

The utility model has the advantages that: after inserting the laryngeal mask to patient, aerify in toward the gas cell through the gas tube, the gas cell inflation, then annotate the medicine through the injection pipe in toward the injection cavity, the cuff passes through the inner wall contact of injection bag with patient's larynx, the injection bag adopts medical grade control release membrane to make, and then can make the liquid medicine in the medicine cavity slowly permeate to the inner wall of patient's larynx through the micropore on the medical grade control release membrane, for example pour into local anesthetic, paralyze the neuromuscular of larynx, thereby effectively reduce the emergence of larynx spasm, realized under the condition that does not interfere the breather pipe and ventilate, can be dosed through the injection pipe at any time.

The utility model is used for the anesthesia operation.

Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions. The utility model provides an each technical feature can the interactive combination under the prerequisite of conflict each other.

With reference to fig. 1 and 2, this is an embodiment of the invention, in particular:

the utility model provides a laryngeal mask of notes medicine type, includes breather pipe 100, the cover body 200, the one end of breather pipe 100 communicates with the middle part of the cover body 200 the edge connection of the cover body 200 has annular cover bag 300, cover bag 300 includes from interior toward the gas cell 310 and the notes medicine bag 320 that set up outward, the cladding of notes medicine bag 320 is in the outside of gas cell 310, the surface of gas cell 310 and the internal surface of notes medicine bag 320 form and annotate medicine cavity 330, gas cell 310 intercommunication has gas tube 340, it is connected with the notes medicine pipe 350 with notes medicine cavity 330 intercommunication to annotate medicine bag 320, it makes to adopt medical-grade control release film to annotate medicine bag 320. When a patient is inserted into the laryngeal mask, the inflatable bag 310 is inflated through the inflation tube 340, the inflatable bag 310 is expanded, then the medicine is injected into the medicine injection chamber 330 through the medicine injection tube 350, the cuff 300 is contacted with the inner wall of the throat of the patient through the medicine injection bag 320, the medicine injection bag 320 is made of a medical-grade controlled release membrane, and further the medicine liquid in the medicine injection chamber 330 can slowly permeate into the inner wall of the throat of the patient through micropores on the medical-grade controlled release membrane, such as local anesthetic injection and neural muscle paralysis of the throat, so that the occurrence of laryngeal spasm is effectively reduced, the medicine can be administered through the medicine injection tube 350 at any time under the condition of not interfering the ventilation of the ventilation tube 100, because the aperture and the number of the micropores on the membrane can be distinguished according to different clinical requirements when the controlled release membrane is produced, the aperture size and the number are controllable, and the onset time and duration time of the medicine given through the medicine injection tube 350 are completely controlled, the function of the laryngeal mask is more diversified.

In a further preferred embodiment, the port of the ventilation tube 100 connected to the cover 200 is inclined. This can match the structure of the larynx for the mask body 200 better realizes sealed contact with the larynx, avoids the phenomenon of gas leakage in the process of ventilating, thereby reduces the occurrence of medical accidents.

Preferably, the vent pipe 100 is curved in an arc shape. This is primarily matched to the person's airway, allowing the laryngeal mask to be better inserted into the patient's larynx for ease of operation by medical personnel.

Further in the preferred embodiment, a one-way inflation valve 341 is installed at an end of the inflation tube 340 away from the airbag 310. The inflation tube 340 is connected to the inflation device through the one-way inflation valve 341, and after the inflation of the airbag 310, the airbag can be pulled out from the inflation device without leakage of air, and does not need to be always connected to the inflation device.

In a further preferred embodiment, a drug injection valve 351 is installed at one end of the drug injection tube 350 far away from the drug injection sac 320. The amount of the injected medicine can be controlled by the medicine injection valve 351, and the operation is convenient.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the foregoing and various other changes, omissions and deviations in the form and detail thereof may be made without departing from the scope of this invention.
