Abstract

A special ventilating laryngeal mask for trachea examination and treatment comprises a ventilating catheter, a mask sac, an air inflation valve and a branch air tube, wherein the mask sac is arranged at the front end of the ventilating catheter and connected with the air inflation valve via an air catheter, and the branch air tube is disposed at the rear end of the ventilating catheter. The special ventilating laryngeal mask is characterized in that the section of the ventilating catheter is oval-shaped, the inner diameter of the catheter is thickened so that an endoscope and a treatment device can pass through the catheter, the rear end of the ventilating catheter is provided with an oval-shaped cap provided with two holes for guiding the endoscope and the treatment device to penetrate therein, and the cap is connected with two plugs capable of plugging the two holes. After applying muscle relaxant to an examinee, the laryngeal mask is inserted in, and after the mask sac is inflated, the endoscope and the treatment device for examination and treatment are inserted from the rear end of the ventilating catheter, thereby finishing examination or treatment of the patient. The section of the ventilating catheter is oval-shaped so as to conveniently contain the endoscope and the treatment device, and the unique inflating mask structure can not affect movement and operation of the internally inserted catheters.

Description

The special-purpose ventilation of air flue inspection treatment laryngeal mask

Technical field

This utility model belongs to technical field of medical instruments, relates to a kind of respiratory tract and checks therapeutic kit, particularly relates to a kind of a kind of general anesthesia assisted ventilation laryngeal mask in respiratory tract inspection treatment usefulness.

Background technology

Check iatrotechnics energy direct observation bronchus pathological changes through fibre bronchus mirror, and can the direct-view under carry out biopsy, through trachea puncture biopsy drug-injection in treatment, can also carry out the burning of tracheal stenosis, granulation removing, micro-wave therapeutic etc., be the important means of respiratory system disease diagnosis and treatment.Also be preceding inspection of conventional art of general thoracic surgery.But certain misery is arranged through fibre bronchus mirror's inspection and treatment, some patient is difficult to cooperation and finishes inspection or therefore refusal inspection, by 100 fibre bronchus mirrors being checked patient's postoperative questionnaire survey, 95% patient thinks that inspection is relatively more painful, 36% patient thinks and is difficult to stand that 75% patient requires to finish inspection under the imperception state.Hypertensive heart disease person's sympathetic stimulation in checking process can cause the heart rate quickening, blood pressure increases and bring adverse effect, the patient who has stress with violent cough under life-threatening complication risk can appear, individual patients state of an illness complexity, the long anoxia that easily causes of review time, patient also is difficult to accept, even often interrupt checking and treatment, the unexpected situation that requires Anesthesia Department's intubate to rescue in inspection and treatment, occurs and also happen occasionally.

Fibre bronchus mirror checks and treats the misery and the harmful effect that can alleviate patient under the state of general anesthesia reservation autonomous respiration, postoperative patient does not have unhappy memory, but exist asphyxia to need the unfavorable factor of face shield assisted ventilation, influence is operated, and the patient who runs into glossoptosis and obesity is especially severe.General anesthesia keeps that fibre bronchus mirror under the state of autonomous respiration checks and treatment have approximately 50% patient in checking process with violent cough, the treatment operation is checked in influence, even the preceding 4% lignocaine atomizing of art sucked 15 minutes, the spraying of pars oralis pharyngis 4% lignocaine, all can't avoid the generation of violent cough, deepen the autonomous respiration that anesthesia influences the patient again.

Existing laryngeal mask airway conduit generally is used for clinical operation anesthesia and critical patient rescues.The laryngeal mask airway conduit is when clinical use, it is inserted into cover capsule front end arrives UES from patient's mouth, through air valve by gas tube after cover capsule inflation, form a ring packing in patient throat, through breather line to external formation one artificial airway, positive airway pressure can be implemented, patient's autonomous respiration can be allowed again.

But existing product meets in clinical use in the time of need inserting splanchnoscopy and treatment in patient's trachea, and insertion process is not smooth, and splanchnoscopy and treatment and patient ventilating can not carry out simultaneously, causes checking and treating and can not carry out smoothly.

Also applied for Chinese utility model patent at above-mentioned defective the applicant, the patent No.: ZL200720073540.8, patent name are the special-purpose ventilation of a kind of general anesthesia auxiliary fiber bronchoscopy laryngeal mask.This laryngeal mask has effectively solved the problem of splanchnoscopy treatment with the ventilation common air duct, but in using, reality finds, this laryngeal mask airway pipeline is big inadequately, endoscope embedded smooth inadequately, top only is provided with the hole that an endoscope is passed, when other treatment of needs was passed through with apparatus, above-mentioned laryngeal mask can't be finished.

The utility model content

Technical problem to be solved in the utility model is, overcomes problems of the prior art, and the special-purpose ventilation of a kind of air flue inspection treatment laryngeal mask is provided.

In order to address the above problem the technical solution of the utility model is such:

The special-purpose ventilation of a kind of air flue inspection treatment laryngeal mask, comprise an airway, be arranged on the cover capsule of airway front end,, have one fen bronchus in the rear end of airway by airway and the charge valve that the cover capsule is connected, it is characterized in that, described airway internal diameter strengthens, and the cross section is oval, and the airway rear end has an oval-shaped pipe cap, have two holes that are used to penetrate endoscope and therapeutic device on the pipe cap, on described pipe cap, be connected with two stoppers that can clog described two holes.This laryngeal mask allows endoscope and therapeutic device simultaneously by not influencing ventilation.

The overstriking of described cover capsule airway internal diameter allows endoscope and other treatment apparatus to pass through, and does not influence ventilation.Various laryngeal masks with breather with the overstriking of difformity internal diameter, allow endoscope and therapeutic device simultaneously by and do not influence ventilation.

Described cover capsule is by the outwards evenly upset of breather front end medial wall.

Also be connected with a pilot balloon between described charge valve and the airway.

This utility model in use, use for those who are investigated and to insert laryngeal mask described in the utility model behind the flesh pine, after the inflation of cover capsule, insert endoscope and the therapeutic device that is used to check treatment from the rear end of airway, can finish inspection or treatment to patient, the airway Cross section Design is that ellipse can conveniently hold endoscope and apparatus is used in treatment, and the ventilation of enough spaces is arranged, and unique inflatable cover structure does not influence the endoscope and motion and the work of treatment with apparatus of insertion.

Beneficial effect, this utility model is simple in structure, and is easy to use, assists laryngeal mask airway in air flue inspection treatment at general anesthesia, ideally solve the problem of existing the laryngeal mask endoscope that exists and the common air duct of ventilating, improved the safety of inspection and patient's comfort level.Also increased treatment simultaneously and inserted path with apparatus, the endoscope that checks treatment can be entered with apparatus simultaneously with treatment does not influence patient ventilating.
