Description

Technical Field

[0001] The utility model relates to the technical field of gastrostomy tubes, in particular to an anti-dislocation gastrostomy tube. Background Art

[0002] Gastrostomy is a nutritional support treatment method for diseases such as swallowing dysfunction and digestive tract tumors. During the operation, the doctor does not remove the patient's esophageal cancer. Generally, a left upper rectus abdominis incision or a midline incision is used, and a hole is punctured through the side abdominal wall to lead out the gastrostomy tube. After the operation, the patient is fed through an external gastrostomy tube. It can not only improve the pain of eating and drinking for esophageal cancer patients, but also achieve the treatment goal.

[0003] The existing anti-dislocation gastrostomy tubes are usually fixed by placing an air bag in the catheter in the body or by a waist fixing belt. However, since the air bag needs to use the internal gas to position the fistula, the gas in the air bag will decrease after a certain period of use, making the fixation of the fistula by the air bag unstable. On the other hand, when the patient walks, lies down, bends over, etc., the fistula will be easily displaced, causing the fistula to shake.

[0004] Therefore, need to invent a kind of new anti-dislocation gastrostomy tube. Summary of the invention

[0005] In order to solve the above problems, the purpose of the utility model is to provide an anti-dislocation gastrostomy tube, which adds an external fixing device while setting an internal airbag, so as to achieve the purpose of strengthening fixation and limit the displacement of the fistula through secondary fixation of the airbag and the external fixing device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] More preferably, the toggle member includes a rotating rod rotatably connected to the top of the groove, a toggle rod and a telescopic rod fixedly connected to both ends of the rotating rod respectively, and a guide rod fixedly connected to the driving end of the telescopic rod; the bottom of the guide rod is fixedly connected to the clamping part and the top is slidably connected to the groove.

[0009] More preferably, an annular groove is formed on the outer side wall of the ostomy catheter, and the two groups of clamping parts clamp the ostomy catheter from both sides of the annular groove respectively.

[0010] More preferably, a return spring is connected between the groove wall and the guide rod.

[0011] More preferably, a rubber layer is provided inside the clamping portion.

[0012] The utility model has the following beneficial effects:

[0013] The utility model can fix the ostomy catheter outside the body through the cooperation of the toggle piece, the clamping part and the ostomy catheter. On the one hand, it can limit the position of the ostomy catheter to avoid shaking of the external end of the ostomy catheter in the patient's daily life, thereby avoiding shaking of the internal end of the ostomy catheter, thereby avoiding displacement of the ostomy catheter. On the other hand, it can strengthen the fixation of the ostomy catheter, solve the problem that the gas in the airbag will be reduced after being used for a period of time, thereby causing shaking of the ostomy catheter, and improve the stability of the ostomy catheter.

[0022] By cooperating with the toggle member 24, the clamping portion 23 and the fistula catheter 1, the fistula catheter 1 can be fixed outside the body. On the one hand, the position of the fistula catheter 1 can be limited to avoid shaking of the external end of the fistula catheter 1 in the patient's daily life, thereby avoiding shaking of the internal end of the fistula catheter 1, thereby avoiding displacement of the fistula catheter 1. On the other hand, the fixation of the fistula catheter 1 can be strengthened to solve the problem that the gas in the airbag 3 will decrease after being used for a period of time, thereby causing the fistula catheter 1 to shake, thereby improving the stability of the fistula catheter 1.
