The utility model provides a three-cavity bendable flushing laryngeal mask airway tube which is applicable to oral treatment.

In an embodiment of the present invention, referring to fig. 1, the three-lumen flexible laryngeal mask airway tube includes a mask body 100, a connecting tube 200, and a sealing cuff 300.

Referring to fig. 1 and 2, the mask body 100 has a breathing chamber 110 and a digestion chamber 120, the breathing chamber 110 is isolated from the digestion chamber 120, the breathing chamber 110 is provided with a breathing opening 111 to communicate the breathing chamber 110 with the respiratory tract, and the digestion chamber 120 is provided with a digestion opening 121 to communicate the digestion chamber 120 with the digestive tract; the connecting tube 200 is connected to the mask body 100, the connecting tube 200 has a breathing lumen 210, a first digestive lumen 220 and a second digestive lumen 230, the breathing lumen 210 is communicated with the breathing chamber 110, both the first digestive lumen 220 and the second digestive lumen 230 are communicated with the digestive chamber 120, during the treatment process, one end of the breathing lumen 210 away from the breathing chamber 110 is connected to a breathing apparatus, one end of the first digestive lumen 220 away from the digestive chamber 120 is connected to a suction source, one end of the second digestive lumen 230 away from the digestive chamber 120 is connected to a positive pressure source or communicated to the atmosphere, or one end of the second digestive lumen 230 away from the digestive chamber 120 is connected to a suction source, and one end of the first digestive lumen 220 away from the digestive chamber 120 is connected to a positive pressure source or communicated to the atmosphere.

In the scheme, when one end of the breathing cavity 210, which is far away from the breathing cavity 110, is connected with a breathing apparatus, one end of the first digestive tract 220, which is far away from the digestive cavity 120, is connected with a suction source, and one end of the second digestive tract 230, which is far away from the digestive cavity 120, is communicated with the atmosphere, the suction source, the first digestive tract 220, the digestive cavity 120, the second digestive tract 230 and the atmosphere form a waste liquid discharge channel, the suction source can suck waste liquid at a digestive opening into the digestive cavity 120, and the waste liquid entering the digestive cavity 120 continuously flows under the action of the suction source and is discharged out of a patient body through the first digestive tract 220, and meanwhile, the breathing apparatus provides breathing gas for the patient through the breathing cavity 210 and the breathing cavity 110, so that the patient breathes. Because the second digestive tract 230 is communicated with the atmosphere, the second digestive tract 230 can supplement corresponding clean gas from the atmosphere to enter the digestive chamber 120 while the suction source pumps away waste liquid and gas in the digestive chamber 120, so that pressure fluctuation in the digestive chamber 120 is small, and transitional negative pressure cannot be generated to a patient. The principle of the second digestive tract 230 connected to the suction source at the end far away from the digestive chamber 120 is the same as that described above, and the first digestive tract 220 connected to the atmosphere at the end far away from the digestive chamber 120 is not described herein again.

In the present scheme, the sealing bag 300 is disposed at the breathing opening 111 and abuts against the wall of the breathing passage to form a seal, and a filling body (not shown in the figure) for flexibly supporting the sealing bag 300 is disposed in the sealing bag 300 to enhance the sealing effect between the sealing bag 300 and the wall of the breathing passage, so that during the treatment process, the breathing opening 111 and the breathing chamber 110 are both isolated from the suction source, the first digestive tract 220, the digestive tract 120, the second digestive tract 230 and the waste liquid discharge passage formed by the atmosphere, and thus during the treatment process, the waste liquid such as saliva, gastric juice and blood generated by the patient enters the digestive tract 120 under the action of the suction source, and is discharged out of the patient through the first digestive tract 220 or the second digestive tract 230 communicated with the digestive tract 120, and the problem that the waste liquid enters the respiratory tract is difficult to occur.

In the process, as the connecting pipe 200 is a flexible pipe, namely, a flexible pipe capable of being bent, the extrusion to the tissues of a patient in the bending process is small, a gap exists between the connecting pipe 200 and the oral cavity wall, so that an operator can change the position of the connecting pipe 200 in the oral cavity more flexibly, and the oral cavity treatment is facilitated, meanwhile, the sealing bag 300 is arranged at the position of the breathing opening 111, a filling body is arranged in the sealing bag 300 and flexibly supports the sealing bag 300, so that the sealing effect is good, and the tissues of the patient are not easily subjected to transitional extrusion, so that the discomfort of the respiratory tract caused by gastric juice, oral secretion or other secretion generated in the mistaken suction treatment process is effectively avoided on the premise that the tissues of the patient are protected by buffering.

In one embodiment, the mask body 100 has an insertion end inserted into the throat, a connection end far away from the insertion end, a front side facing the respiratory tract, and a rear side facing away from the respiratory tract, the connection tube 200 is connected to the connection end, the respiration opening 111 is disposed at the front side, the digestion opening 121 is disposed at one end of the rear side close to the insertion end, and the respiration chamber 110 and the digestion chamber 120 share a side wall. In the treatment process, the front side is inserted towards the breathing opening 111, and as the patient is usually in a supine state in the treatment process, the breathing chamber 110 is positioned above the digestion chamber 120 after the cover body 100 is inserted, namely the breathing opening 111 faces upwards, the digestion opening 121 faces downwards, and in the process that gastric juice, oral secretion or other secretion generated in the treatment process enters the digestion chamber through the digestion opening 121 and is discharged out of the body, liquid easily flows downwards under the action of gravity, so that the gastric juice, the oral secretion or other secretion is not easy to contact with the breathing opening 111, and the probability of mistaken absorption of gastric juice, the oral secretion or other secretion is further reduced. The use of a sidewall for both the breathing chamber 110 and the digestion chamber 120 saves on the one hand the material required for the manufacture of the mask body 100, on the other hand reduces the volume of the mask body 100 and makes the mask body 100 more flexible and thus more comfortable for the patient.

In one embodiment, the sealing bag 300 is an annular bag, and the shape of the sealing bag 300 is the same as the shape of the breathing opening 111, so that after the mask body 100 is inserted, the sealing bag 300 can be in contact with the wall of the breathing passage to a greater extent, thereby achieving a better sealing effect and further reducing the probability of aspiration of gastric juice, oral secretion or other secretion.

In some embodiments, the hardness of the filler body is between 2HA and 10HA, i.e. the hardness of the filler body is between 2 degrees and 10 degrees shore hardness. Not only can play a supporting role for the sealing bag 300, but also can lead the tissues of the patient to be less stressed.

In one embodiment, the hardness of the filling body is 5HA, so that the supporting effect and the softness are moderate.

In an embodiment, the obturator is TPE, and what sealed capsule 300 was filled is thermoplastic elastomer promptly for the intensity of obturator is high, the resilience is high, the sense of touch is soft, thereby makes sealed capsule 300 more laminate patient's tissue, and can change the shape along with patient's tissue's activity more nimble, and then reach sealed effect better, reduces the oppression to patient's tissue again simultaneously.

In some embodiments, the filling body is a gas or a liquid, and the gas or the liquid is filled in the sealing bag 300, so that the sealing bag 300 has high fluidity, and the shape can be changed more flexibly, so that the sealing bag can be more fitted to the tissues of a patient, and the sealing effect is enhanced.

Referring to fig. 3, in an embodiment, a spring 240 is disposed in the connection pipe 200, and the extension direction of the spring 240 is the same as the length direction of the connection pipe 200, so that in the process of oral treatment, on one hand, the spring 240 can support the connection pipe 200, so that the inner wall of the connection pipe 200 is not attached, and therefore the connection pipe 200 is smooth, and on the other hand, the connection pipe 200 can be bent and deformed more flexibly, and the inner wall of the connection pipe 200 is not attached in the process of bending and deformation, so that oral treatment is facilitated.

In one embodiment, the spring 240 is disposed within the respiratory tract 210. Since gastric juice, oral secretion or other secretion may pass through the digestive tract in the treatment process, the spring 240 is disposed in the respiratory tract 210, so that the spring 240 is prevented from being polluted by the gastric juice, the oral secretion or other secretion, and the probability that the gastric juice, the oral secretion or other secretion blocks the connecting pipe 200 together with the spring 240 can be reduced.

In one embodiment, the sealing bag 300, the connecting tube 200 and the cover body 100 are integrally formed, so that the manufacturing process is convenient, and the integral forming makes the connecting position smoother, thereby making the discomfort of the patient after the insertion less.

The above is only the optional embodiment of the present invention, and not therefore the limit of the patent scope of the present invention, all of which are in the concept of the present invention, the equivalent structure transformation of the content of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
