The engaging member 30 is adapted to be engaged by a patient in the mouth, and on the one hand, assists the patient in keeping the mouth open, and on the other hand, the engaging member 30 is coupled to the flexibly deformable tube member 10 to keep the gastroscopic pharynx expanding apparatus for elderly patients fixed in the mouth.
The inflation module 40 is connected to the balloon-expander 20 for inflating the first balloon H21 and the second balloon H22, and when the balloon-expander 20 is inserted into the pharynx, the inflation module 40 can be used to inflate the balloon-expander 20, so that the pharynx of the patient can be expanded by the first balloon H21 and the second balloon H22.
According to the pharynx expanding device for the gastroscopy of the elderly patients, which is provided by the embodiment of the invention, the bendable deformable pipe fitting 10 can be used for the gastroscopy pipe 60 to pass through and penetrate into the stomach of the patients from the mouths of the patients, the air bag expanding piece 20 is used for inflating and expanding to expand the pharynx of the patients, and the gastroscopy pipe 60 slides downwards again, so that on one hand, the insertion of the gastric tube is facilitated after the pharynx is expanded, on the other hand, the gastric tube passes through the bendable deformable pipe fitting 10 and cannot be rubbed with the pharynx to cause stimulation, the nausea and vomiting are not easy to cause, the gastroscopy can be performed more smoothly under the condition of no anesthesia, and the pharynx expanding device is more friendly and comfortable for the patients.
It should be noted that in this application, the term "proximal" refers to the end that is closer to the human body in use, and "distal" refers to the end that is further away from the human body in use.
Further, the balloon-expanding member 20 is extended to a depth of 10cm to 15cm, and the balloon-expanding member 20 is expanded to the pharynx with a width that allows the gastroscope tube to smoothly pass therethrough, and the width of the gastroscope tube is generally 8.9 to 13.5 mm.
In one embodiment of the present invention, the balloon dilator 20 comprises an inner balloon 201, an outer balloon 202 and a collar, wherein the inner balloon 201 is formed into a tubular structure and is sleeved on the proximal end of the bendable deformable tube 10.
The outer-layer balloon membrane 202 is located outside the inner-layer balloon membrane 201, the outer-layer balloon membrane 202 comprises a first inflation portion 2021 and a second inflation portion 2022 which are connected, the first inflation portion 2021 and the second inflation portion 2022 are axially arranged at intervals at the proximal end of the bendable deformation pipe 10, the first inflation portion 2021 and the inner-layer balloon membrane 201 define therebetween the first inflation portion, and the second inflation portion 2022 and the inner-layer balloon membrane 201 define therebetween the second inflation portion.
And the binding ring is sleeved at the joint of the first expansion part 2021 and the second expansion part 2022 to limit the expansion of the joint of the first expansion part 2021 and the second expansion part 2022.
One end of the first expansion portion 2021, which is far away from the second expansion portion 2022, is hermetically connected with one end of the inner layer balloon 201, and one end of the second expansion portion 2022, which is far away from the first expansion portion 2021, is hermetically connected with the other end of the inner layer balloon 201.
That is, the balloon dilator 20 mainly comprises an inner balloon 201 and an outer balloon 202, the inner balloon 201 is sleeved on the proximal end of the inner tube 101, the outer balloon 202 is located outside the inner balloon 201, and two ends of the outer balloon 202 are sealed with two ends of the inner balloon 201, so that an inflation space can be formed between the inner balloon 201 and the outer balloon 202. In addition, the outer-layer bag 202 has the first inflation part 2021 and the second inflation part 2022 which are axially arranged at intervals, when the inflation space is inflated, the first inflation part 2021 and the second inflation part 2022 are inflated outwards, and the connection part between the first inflation part 2021 and the second inflation part 2022 cannot be inflated due to the restriction of the bundle ring, so that the first inflation part 2021 and the second inflation part 2022 can be made to abut against the inner wall of the pharynx after being inflated respectively, and thus, by adopting the structure, the first bag H21 and the second bag H22 can be easily formed, the structure is simple, and when the inflation space is inflated, the first bag H21 and the second bag H22 can be ensured to be inflated.
In some embodiments of the present invention, the bendable deformation tube 10 comprises an inner tube 101 and an outer tube 102, wherein the inner tube 101 is adapted for passing the gastroscope tube 60 therethrough, and the outer tube 102 is slidably sleeved on the outer tube 101. The balloon expansion member 20 is sleeved on one end of the inner tube 101, the proximal end of the balloon expansion member 20 is connected with the inner tube 101, the distal end of the balloon expansion member 20 is connected with the proximal end of the outer tube 102, and when the outer tube 102 slides relative to the inner tube 101, the balloon expansion member 20 is pressed from two ends to the middle.
In the pharyngeal dilation process by using the pharyngeal dilation apparatus for gastroscopy of the elderly patient, after the proximal end of the bendable deformation tube 10 is inserted into the pharyngeal portion of the patient, the balloon dilator 20 is inflated by the inflation assembly 40, so that the first balloon H21 and the second balloon H22 on the balloon dilator 20 are inflated, and the first balloon H21 and the second balloon H22 are abutted against the inner wall of the pharyngeal portion. Since the inflation amount of the inflation assembly 40 is difficult to be accurately controlled when the inflation assembly is inflated, and accordingly, it is difficult to control the first balloon H21 and the second balloon H22 to be further inflated to a smaller extent after the first balloon H21 and the second balloon H22 are inflated to a certain extent to abut against the inner wall of the pharynx, and in this case, the first balloon H21 and the second balloon H22 are not suitable for being inflated to a large extent, which is likely to cause discomfort to the patient and even damage to the pharynx due to an excessive pressure, in order to control the inflation of the first balloon H21 and the second balloon H22 to a small extent, in the present embodiment, the proximal end of the balloon dilator 20 is connected to the inner tube 101, the distal end of the balloon dilator 20 is connected to the proximal end of the outer tube 102, and the inner tube 101 and the outer tube 102 can slide relative to each other, so that after the first balloon H21 and the second balloon H22 are inflated to a certain extent to abut against the inner wall of the pharynx, can promote outer tube 102 and inner tube 101 relative slip, and then make gasbag extension piece 20 extrude to the centre from both ends, so, first utricule H21 and second utricule H22 can be at extrusion in-process radial expansion, further support and hold the inner wall at the pharynx, this kind of regulative mode, only need control inner tube 101 and outer tube 102 between the distance of relative motion can, control accuracy is high, can realize the regulation of small range, and with the help of the regulation of small range, both can ensure that gasbag extension piece supports with the pharynx and holds fixedly reliable, can avoid too big the patient that causes of pressure not or cause the damage scheduling problem to the pharynx again.
