Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a gastrointestinal tube device that can be used for dilation treatment of esophageal stenosis. Background Art
[0002] Sabour bougie dilatation and balloon dilatation are two commonly used methods for dilating strictures in clinical practice. Bougie dilatation can produce both longitudinal and radial pressures, while balloon dilatation mainly produces radial pressure, which can theoretically reduce the probability of esophageal injury. Bougie dilatation and balloon dilatation have similar efficacy in treating benign esophageal strictures. The diameters of Sabour bougies are generally 5, 7, 9, 11, 13, and 15 mm, and the diameters of balloons are generally 6, 8, 10, 12, 14, 16, 18, and 20 mm. Both Sabour bougie dilatation and balloon dilatation require endoscopic operation. Some patients who cannot tolerate anesthesia suffer great pain, and dilatation is generally performed once a week, and multiple dilatations cannot be repeated in a short period of time.
[0003] Although there is currently an in vitro self-expansion balloon that can be used to prevent postoperative esophageal stenosis, it still requires endoscopic placement and cannot help patients resume eating in the short term. In addition, the in vitro self-expansion balloon is relatively large and is not suitable for esophageal stenosis, and the expansion position and effect cannot be monitored. Therefore, in response to the above-described technical problems, a new gastrointestinal tube device that can be used to treat esophageal stenosis is urgently needed. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the pain of patients when dilating a narrow esophagus under gastroscopy and the difficulty of being unable to repeat the dilation multiple times in a short period of time, and to provide a new gastrointestinal tube device that can be used for the dilation treatment of esophageal stricture.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is a gastrointestinal tube device that can be used for the treatment of esophageal stenosis: comprising a gastrointestinal tube body with an expandable balloon, a Y-type connector with a sealing plug, a three-way connector, a syringe, a manometer, and a guide wire with a grip handle;
[0006] The gastrointestinal tube body is made of a radiopaque filler, and an expandable balloon is arranged in the middle of the gastrointestinal tube body. The expandable balloon is made of a contractible material and is tightly attached to the gastrointestinal tube when not inflated, making it easy to insert;
[0007] The top of the gastrointestinal tube body is provided with a Y-shaped connector, and the top of the Y-shaped connector is provided with a sealing plug;
[0008] The three-way connector is inserted into one end of the sealing plug of the Y-type connector;
[0009] The syringe is communicated with the side wall opening of the three-way connector;
[0010] The pressure tester is in communication with the top opening of the three-way joint;
[0011] The guide wire is arranged in the inner cavity of the gastrointestinal tube body, and the top end extends out from the non-sealing plug connecting end of the Y-type connector and is provided with a holding handle.
[0012] As an improvement, an expandable balloon is provided in the middle of the gastrointestinal tube body.
[0013] As an improvement, the end of the gastrointestinal tube body below the expandable balloon is provided with a distal port, and the side wall is provided with two side ports.
[0014] As an improvement, the outer layer of the guide wire is provided with a polytetrafluoroethylene coating, the outer section of the guide wire is connected to a larger gripping handle, the connection between the gripping handle and the guide wire is made of a shearable material, the guide wire is an ultra-smooth guide wire, a nitinol hydrophilic guide wire, covered with tungsten-containing polyurethane and a hydrophilic polymer coating, and has a rounded end.
[0015] As an improvement, the side end of the Y-shaped connector is connected to the three-way connector to form a balloon cavity connector, and the other straight end is a gastrointestinal cavity connector.
[0016] Compared with the prior art, the utility model has the following advantages: the utility model patent avoids endoscopic operation and can be directly inserted. If insertion is difficult, an ultra-smooth guide wire can be inserted first, and then the gastrointestinal tube can be inserted through the guide wire to relieve the patient's pain. The opaque guide wire and gastrointestinal tube can confirm the intubation position and expansion effect through X-ray, and at the same time have the function of a gastrointestinal tube to restore the patient's enteral nutrition as soon as possible. At the same time, a manometer is configured to facilitate the control of the balloon expansion hardness with a syringe. When the pressure is reduced, the patient can pull it out appropriately. When the balloon is fully deflated, it can be inserted again to ensure safety and expansion effect. BRIEF DESCRIPTION OF THE DRAWINGS
