Description
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to a disposable laryngeal mask.
Background
Flexible bronchoscopy (including fiberbronchoscopy, electronic bronchoscopy; hereinafter referred to as bronchoscopy) is an important means for clinical diagnosis and treatment of respiratory diseases, and has been widely used in clinic. Bronchoscopy laryngeal masks in the prior art generally comprise a cuff, a laryngeal mask cannula and an inflation tube, wherein the cuff is respectively connected with one end of the laryngeal mask cannula and one end of the inflation tube, and the other end of the inflation tube is provided with an inflation valve so as to inflate the cuff. The single-cavity laryngeal mask can lead to limited space of the laryngeal mask cannula when the bronchoscope is inserted into the laryngeal mask cannula, so that ventilation of a patient is affected, and meanwhile, the flexibility of the bronchoscope is limited. On this basis, a double-cavity laryngeal mask has been developed by those skilled in the art to separate the airway from the access tract of the bronchoscope, ensuring that the airway remains clear and the patient is ventilated when the bronchoscope is in use. However, the two cavities of these dual-cavity laryngeal masks share a common airway, and therefore the access airway is much narrower than the access airway of conventional single-cavity laryngeal masks, and bronchoscopes must be advanced into the airway along the narrow access airway. Because partial manipulation during use of the bronchoscope requires bending of the scope body to control the lens orientation, it is difficult for a physician to manipulate the bronchoscope in such a dual-lumen laryngeal mask and even possible damage to the bronchoscope.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a disposable laryngeal mask, which ensures that the bronchoscope does not occupy the airway space and provides a relatively loose movable space for the operation of the bronchoscope.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a disposable laryngeal mask, includes the laryngeal mask intubate, the end cover of laryngeal mask intubate has the body cover bag of making, the body cover bag of making passes through the gas tube and links to each other with the pump, the cross-sectional shape of laryngeal mask intubate is the "concave" font that one side had the depressed part, the depressed part be in the laryngeal mask intubate with the junction of body cover bag is equipped with bronchoscope access.
Preferably, one end of the bronchoscope access passage facing the body making cuff is provided with a one-way valve, the inside of the other end is provided with an inflatable and then sealed access passage cuff, and the access passage cuff is connected with the inflator pump through an inflation tube.
Preferably, the middle section of the laryngeal mask cannula is sleeved with a hard collar for bearing the bite pressure.
Advantageous effects
When the laryngeal mask is used, the concave part arranged at one side of the laryngeal mask intubation provides a movable space for the bronchoscope, and compared with the multi-cavity laryngeal mask in the prior art, the bronchoscope has a larger movable range, ensures flexibility and does not influence the laryngeal mask intubation to ventilate a patient.

Detailed Description
The utility model will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present utility model and are not intended to limit the scope of the present utility model. Further, it is understood that various changes and modifications may be made by those skilled in the art after reading the teachings of the present utility model, and such equivalents are intended to fall within the scope of the claims appended hereto.
As shown in FIG. 1, the present utility model provides a disposable laryngeal mask comprising a laryngeal mask cannula having a body cuff sleeved on the distal end of the laryngeal mask cannula, the body cuff being connected to an inflator via an inflation tube. The laryngeal mask cannula is a hollow tube, and the cross section of the laryngeal mask cannula is concave with a concave part at one side. The laryngeal mask cannula is used as a main ventilation pipe, the outer end of the laryngeal mask cannula is connected with a breathing machine or an anesthesia machine, and the inner end opening is positioned in the center of the body making cuff and communicated with the throat of a patient.
In a specific embodiment, the recess is located on the inside of the laryngeal mask and extends along the length of the laryngeal mask cannula. The concave part is provided with a bronchoscope access passage at the joint of the laryngeal mask cannula and the body making cuff, the bronchoscope access passage is a hollow tube, one end of the bronchoscope access passage facing the body making cuff is provided with a one-way valve, the inside of the other end of the bronchoscope access passage is provided with an inflatable back-sealed access passage cuff, and the access passage cuff is connected with the inflator pump through an inflation tube. The one-way valve is positioned at one side of the opening at the inner end of the laryngeal mask cannula, and pollutants in the trachea of a patient are prevented from being carried out when the bronchoscope is withdrawn through the one-way valve and the detection channel cuff.
The middle section of the laryngeal mask cannula is sleeved with a hard lantern ring for bearing the occlusal pressure of teeth. In one embodiment, the rigid collar is provided with a socket for mating with the upper and lower incisors, into which the patient can engage the teeth to prevent laryngeal mask play and achieve a more comfortable use experience. The hard collar can slide along the laryngeal mask cannula within a certain range to fit patients of different mouth shapes and is fixed outside the laryngeal mask cannula through a buckle after confirming the proper position.
When the disposable laryngeal mask is used, after the disposable laryngeal mask is placed in place, the bronchoscope passes through the hard lantern ring along the concave part; the head end is aligned with the uninflated detection channel cuff and then inserted into the bronchoscope detection channel, and then the detection channel cuff is inflated to prevent pollutants from flowing out of the detection channel during detection; finally, the lens passes through the one-way valve and enters the bronchus of the patient to perform detection operation.
