Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

Referring to fig. 1, a first embodiment of the present invention provides an endotracheal tube 1, which includes a tube body 11, an elbow 12 and a filter 13, wherein one end of the tube body 11 is connected to the elbow 12, and the other end is used for being inserted into an endotracheal tube. One end of the elbow 12 is connected with the conduit body 11, the other end of the elbow is connected with the filter 13, and two ends of the elbow 12 are bent by a preset angle. The trachea of the patient flows through the catheter body 11 to the elbow 12 and finally flows through the filter 13 and out of the external equipment.

Through setting up elbow 12, elbow 12 buckles and predetermines the angle, makes spun saliva or sputum pass through in the pipe body 11 elbow 12 changes spun angle, prevents that medical personnel from the risk of saliva or sputum towards medical personnel departure that leads to when giving patient treatment or change equipment, has protected medical personnel, increases equipment safety in utilization. Meanwhile, the bent elbow 12 enables the foreign matters sprayed out of the trachea of the patient to be partially blocked in the elbow 12, reduces the accidental spraying of the foreign matters, and further increases the use safety of the equipment. Furthermore, by additionally arranging the filter, foreign matters sprayed out of the trachea can be completely blocked by the filter 13, sprayed gas can pass through the filter 13 to realize filtering, and meanwhile, gas injected into the trachea can also be filtered by the filter 13, so that the infection of respiratory diseases is effectively avoided, medical personnel and patients are further protected, and the use safety of equipment is improved.

It can be understood that when elbow 12 is buckled the angle and is too big, can effectively block unexpected spun foreign matter, but buckle too big elbow 12 and can hinder the smooth and easy of patient's breathing, on the contrary, if buckle the angle when too little, can guarantee the smooth and easy nature of patient's breathing, but the effect of blockking the foreign matter can reduce, so, as an preferred embodiment, the angle of predetermineeing of elbow 12 both ends bending is 90, also promptly elbow 12 is L type structure return bend, has guaranteed that the patient breathes smoothly, has also ensured to block the unexpected spun effect of part foreign matter through elbow 12. Of course, the preset angle of bending the elbow 12 may also be other angles, such as 30 °, 60 ° or 120 °, which is not described herein again.

Optionally, the outer surface of the elbow 12 is covered with a layer of absorbent cotton (not shown), and the absorbent cotton is arranged to reduce the residue of water vapor on the surface of the elbow 12 when the elbow 12 is contacted with the oral cavity of a patient, and particularly, when the elbow 12 sinks into the oral cavity of the patient, the accumulation of saliva in the oral cavity of the patient can be reduced, and the wearing comfort of the patient can be improved.

It will be appreciated that the filter 13 is a disposable breathing filter, and that the filter 13 is provided with a filtering membrane, typically made of polypropylene and composite material according to YY/T0242, for filtering the particles contained in the gas.

Referring to fig. 1, a through hole 121 is formed in the elbow 12, the conduit body 11 is connected to a guiding strip 14, one end of the guiding strip 14 passes through the through hole 121, and the other end is exposed to the through hole 121, and the guiding strip 14 is a hard guiding strip.

It can be understood that the guiding strip 14 is a pulling object used for pulling the catheter body 11 to insert into the trachea in the endotracheal tube 1, and since the catheter body 11 is a soft catheter, which is inconvenient when the trachea is inserted, the hard guiding strip 14 is used for guiding the catheter body 11 to be accurately inserted into the trachea, and after the insertion operation is completed, the guiding strip 14 is pulled based on the through hole 121 to draw the guiding strip 14 out of the catheter body 11, so that the hard guiding strip 14 is prevented from remaining in the catheter body 11.

Optionally, a sealing cover 122 is connected to the elbow 12, and the sealing cover 122 can cover and seal the through hole 121, so that when the guide strip 14 is pulled out from the through hole 121, the sealing cover 122 seals the through hole 121, and thus, the air leakage of the patient during use is prevented.

It will be appreciated that the sealing cap 122 is connected to the elbow 12 by a strip of glue to prevent the sealing cap 122 from falling off. The sealing cover 122 may not be provided, and the medical staff may seal the through hole 121 by providing an external sealing device, such as a rubber plug.

With continuing reference to fig. 1, the catheter body 11 is further provided with an inflation cuff 111 and a catheter cuff 112, the inflation cuff 111 is communicated with the catheter cuff 112, the catheter cuff 112 is arranged at one end of the catheter body 11 away from the elbow 12, and the catheter cuff 112 is inflated based on the inflation cuff 111, so that the catheter cuff 112 can be inflated to a predetermined size according to the needs of a user to seal the gap between the catheter body 11 and the trachea of a patient, prevent the air leakage phenomenon after the catheter body 11 is placed in the catheter body, and increase the air tightness of the device.

Be equipped with locating clip 131 on the filter 13, the inflatable cuff 111 is located on locating clip 131, avoided the interior inflatable cuff 111 of current endotracheal tube to lack fixed phenomenon, increase device safety in utilization, also made things convenient for the operation of medical personnel when aerifing.
