Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a double-balloon cannula used for gastrointestinal endoscopic treatment. Background Art

[0002] Clinically, gastrointestinal bleeding, food residues and large amounts of secretions from patients often affect the treatment effect of gastrointestinal lesions under gastroenteroscopy. The reason is that in a narrow space, under the interference of blood and secretions, the suction and cleaning function of the gastroenteroscopy is limited, which affects the field of view under the gastroenteroscopy, and thus affects the doctor's diagnosis and treatment of the patient's lesion location;

[0003] The existing double-balloon cannula is a commonly used clinical device for endoscopic treatment of the gastrointestinal tract. By inflating the balloon, the cannula can come into contact with the stomach and intestines, thereby achieving a hemostatic effect. Subsequently, the condition of the inner wall of the stomach and intestines can be observed through gastroscopy for diagnosis and treatment. However, in clinical use, the patient's own secretions often fall into the cannula, thereby affecting the field of view and the doctor's diagnostic efficiency.

[0004] In view of the above problems, a double-balloon cannula for gastrointestinal endoscopic treatment is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a double-balloon cannula for gastrointestinal endoscopic treatment, which solves the problem in the background art that the patient's own saliva secretions or food residues fall into the cannula and affect the diagnosis, and can increase the comfort of gastroscope insertion.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a double-balloon cannula for gastrointestinal endoscopic treatment, comprising a main tube; a first outer balloon, located at the bottom end of the outer side wall of the main tube; a second outer balloon, located at the outer side wall of the main tube; a protective mechanism, located inside the main tube; an outer balloon inflation valve, fixed to the top end of the outer side wall of the main tube; a protective inflation valve, fixed to the top end of the outer side wall of the main tube; the protective mechanism comprises a protective balloon, an arc-shaped member, a connecting member and a collecting concave plate; the inner side wall of the main tube is fixedly connected with the protective balloon, the inner side wall of the protective balloon is fixedly connected with the arc-shaped member, a through-type connecting groove is formed inside the arc-shaped member, a connecting member is provided between the two groups of arc-shaped members, both ends of the connecting member are located inside the connecting groove, and a collecting concave plate is fixedly connected to the surface of the arc-shaped member.

[0007] As a further description of the above technical solution: the outer wall of the main pipe is slidably connected with a fixed membrane, the outer wall of the fixed membrane is fixedly connected with a hanging ear, the rear surface of the fixed membrane is integrally formed with a rubber film, and the fixed membrane is made of medical breathable cotton.

[0008] As a further description of the above technical solution: the inner side wall of the main pipe is fixedly connected with a covering plate, the covering plate is in contact with the collecting concave plate, the covering plate is an annular structure, and the inner diameter of the covering plate is smaller than the inner diameter of the collecting concave plate.

[0009] As a further description of the above technical solution: the main pipe is made of rubber PVC.

[0010] As a further description of the above technical solution: a cleaning cotton ball is fixedly connected to the interior of the collecting concave plate.

[0011] As a further description of the above technical solution: a protection pipe is connected between the protection inflation valve and the protection airbag, the outer airbag inflation valve is connected to the first outer airbag and the second outer airbag through the protection pipe, and the protection pipe is a rubber tube.

[0012] As a further description of the above technical solution: an air stop valve is fixedly connected to the outer side of the main pipe, the outer air bag inflation valve and the protective inflation valve both penetrate the air stop valve, and an air stop clamp is slidably connected to the inside of the air stop valve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides a double-balloon cannula for gastrointestinal endoscopic treatment. By inserting a main tube into the patient's intestine, the first outer balloon and the second outer balloon can contact the gastrointestinal tract when they are expanded, so as to stop bleeding and expand and block the tube. A protective mechanism is provided inside the main tube. The protective mechanism can compress the space by expansion to avoid collision with the main tube due to excessive speed when the gastroscopic tool is inserted later. After the protective mechanism is deployed, the collecting concave plates can be merged, and then the saliva secretions and residues in the esophagus produced by the patient himself can be collected through the grooves in the collecting concave plates after accidentally entering the main tube, so as to avoid visual impact caused by flowing into the detection position in the main tube.

[0016] 2. The present invention provides a double-balloon cannula for gastrointestinal endoscopic treatment. The positioning mechanism fixes the patient's main tube, and the first airbag, the second airbag, and the protective airbag are inflated and deflated through the outer airbag inflation valve and the protective inflation valve, thereby expanding or contracting to achieve better adjustment and control.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0024] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a main pipe 1; a first outer airbag 2, located at the bottom end of the outer wall of the main pipe 1; a second outer airbag 3, located at the outer wall of the main pipe 1; a protection mechanism 4, located inside the main pipe 1; an outer airbag inflation valve 5, fixed to the top of the outer wall of the main pipe 1; a protection inflation valve 6, fixed to the top of the outer wall of the main pipe 1; the protection mechanism 4 includes a protection airbag 401, an arc-shaped member 402, a connecting member 403 and a collecting concave plate 404; the inner wall of the main pipe 1 is fixedly connected with the protection airbag 401, The inner wall of the protection airbag 401 is fixedly connected with an arc-shaped piece 402, and a through-type connecting groove 405 is formed inside the arc-shaped piece 402. A connecting piece 403 is provided between the two groups of arc-shaped pieces 402, and both ends of the connecting piece 403 are located inside the connecting groove 405. A collecting concave plate 404 is fixedly connected to the surface of the arc-shaped piece 403. When the protection airbag 401 expands, the arc-shaped piece 402 moves relatively. Due to the limitation of the arc-shaped piece 403, the collecting concave plate 404 forms a collecting effect.

[0025] Combination Figure 1The outer wall of the main pipe 1 is slidably connected with a fixed membrane 7, and the outer wall of the fixed membrane 7 is fixedly connected with a hanging ear 8. The rear surface of the fixed membrane 7 is integrally formed with a rubber film. The fixed membrane 7 is made of medical breathable cotton material. The fixed membrane 7 is in contact with the patient's mouth or throat and fixed. When it is in contact with the throat and fixed, the rubber film can be torn off, and then it is in contact with the patient's skin to form a fit and fixation. Then the hanging ear 8 forms a sleeve with the ear to increase stability and prevent it from falling. The outer side of the main pipe 1 is fixedly connected with an air stop valve 12, and the outer air bag inflation valve 5 and the protective inflation valve 6 both penetrate the air stop valve 12. The inside of the air stop valve 12 is slidably connected with an air stop clamp 13. After inflation is completed, the two air stop clamps 13 are relatively moved to clamp and fix the outer air bag inflation valve 5 or the protective inflation valve 6 to avoid gas leakage or the need for continuous inflation to ensure the expansion of the equipment.

[0026] Combination Figure 2 A covering plate 9 is fixedly connected to the inner wall of the main pipe 1, and the covering plate 9 is in contact with the collecting concave plate 404. The covering plate 9 is an annular structure, and the inner diameter of the covering plate 9 is smaller than the inner diameter of the collecting concave plate 404. The covering plate 9 does not delay the later observation and treatment, and can block the collecting concave plate 404 at the beginning. A cleaning cotton ball 10 is fixedly connected to the inside of the collecting concave plate 404. When the collecting concave plate 404 moves relatively to form a ring, the collecting concave plate 404 can collect saliva secretions or food residues, and the leaked cleaning cotton ball 10 can absorb the saliva secretions. The covering plate 9 contacts the collecting concave plate 405 to form a cover to prevent the waste from falling again when it is taken out.

[0027] Combination Figure 2 The size of the collecting concave plate 404 is larger than that of the arc-shaped piece 402, and the two collecting concave plates 404 are matched with each other. As the protective airbag 401 expands, the arc-shaped piece 402 moves relatively, and the collecting concave plates 404 move relatively to form a ring shape, ensuring the doctor's observation while protecting and collecting the inner wall.

[0028] Working principle: the user inserts the main tube 1 into the patient's stomach and intestines, and then expands the first outer airbag 2 and the second outer airbag 3 through the outer airbag inflation valve 5, so as to contact the patient's stomach and intestines. The second outer airbag 3 stops bleeding at the bleeding position and expands the field of vision, and then inserts the gastroscope. When the gastroscope is inserted, the protective mechanism 4 is provided in the main tube 1, so as to avoid the discomfort caused by the gastroscope being inserted too quickly or directly touching the patient's stomach and intestines through the main tube;

[0029] When saliva secretions or residues fall into the main tube 1, the arc-shaped member 402 is pushed by the inflated protective airbag 401, and the collecting concave plate 404 forms a closed annular groove under the limitation of the connecting member 403 to collect the secretions, thereby preventing continuous falling from affecting the observation effect of the gastroscope and providing a better field of vision.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
