Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a gastrostomy tube. Background Art

[0002] A gastrostomy tube is a type of medical device. It is a thin and flexible tube that is surgically inserted into the patient's stomach to create an artificial channel directly from the abdominal wall to the gastric cavity. This operation is mainly used for patients who cannot take food and liquids orally for various reasons, or who need long-term nutritional support. The operation is usually performed under local or general anesthesia, and the doctor will make a small incision at a selected location in the patient's abdomen. The gastrostomy tube is then passed through the abdominal wall tissue through the incision to the gastric cavity, and is usually fixed to the anterior wall of the stomach. One end of the tube remains in the stomach, and the other end passes through the skin and extends to the outside of the body to form a visible external interface. The gastrostomy tube can directly inject nutritious liquid food to ensure that the patient obtains the necessary calories, protein, vitamins and minerals to maintain the body's metabolic needs. Certain oral medications can be given through the gastrostomy tube.

[0003] The connection between the gastrostomy tube and the patient's abdomen will form a stoma, that is, an incision. Medical staff need to regularly clean the skin around the stoma to keep it dry and prevent infection. When the patient performs strenuous exercise or changes body position frequently, the tube may rub against the fistula, affecting healing and inducing leakage. Leakage not only hinders the normal healing of the fistula, but may also cause the healed part to reopen or become infected. Existing gastrostomy tubes use fixing devices such as sutures and patches to ensure that the tube is stable inside the fistula and reduce leakage caused by displacement.

[0004] A gastrostomy tube with Chinese patent application number 202022531647.0 is provided, which includes a fluid esophagus, a first funnel, a water inlet pipe and a second funnel, and also includes a truncated cone-shaped sealed water bag located in the stomach, one end of the fluid esophagus is connected to the stomach 1, and the other end is connected to the first funnel, one end of the water inlet pipe is connected to the inside of the truncated cone-shaped sealed water bag, and the other end is connected to the second funnel, and the truncated cone-shaped sealed water bag is provided with a central hole, and the truncated cone-shaped sealed water bag is sleeved on the fluid esophagus through the central hole, and the plane of the truncated cone-shaped sealed water bag is sealed and connected to the inner side of the stomach wall opening. Its beneficial technical effect is: the truncated cone-shaped sealed water bag reduces the stimulation to the gastrostomy opening and the pressure on the gastric mucosal blood vessels, and avoids ischemic necrosis of the gastric mucosa. It has the characteristics of good sealing performance, preventing gastric fluid from leaking, and reducing the infection rate of the gastrostomy opening. The gastrostomy tube is provided with a sealing gasket at the connection between the tube body and the abdomen to prevent leakage at the connection, but the sealing effect of the sealing gasket is poor and it is difficult to meet the needs of use.

[0005] During use, the existing gastrostomy tube has low protection for the connection between the fistula tube and the patient's abdominal incision, which easily leads to liquid leakage at the connection, increasing the risk of infection for the patient. Utility Model Content
