Gastrostomy is a nutritional support treatment method for preventing and treating swallowing dysfunction, anorexia, upper gastrointestinal tumor and other diseases caused by various reasons. Although the gastrostomy tube can be left in the patient for a long time, a certain retention period exists, and after the retention period is reached, the gastrostomy tube needs to be replaced, the old gastrostomy tube is removed, and a new gastrostomy tube is replaced to meet the nutrition requirement in the gastrointestinal tract of the patient. The traditional gastrostomy replacement tube device has poor fitting degree, poor plasticity, small coverage area and easy damage, so that gastrointestinal contents overflow from a gap between a fistula tract and a catheter, and complications such as early falling off of a fistulization tube, growth of granulation tissue at an external stoma of the fistulization, bleeding, infection and the like are caused, the living quality and nutrition improvement of a patient can be seriously influenced, and the gastrostomy failure is caused by serious infection and bleeding. Meanwhile, the traditional external fixing pad of the gastrostomy replacement tube is of a plastic disc-mounted structure, has poor plasticity and poor fitting degree, stimulates the growth of granulation tissue of the fistulization external orifice, increases the probability of exudation and infection, and therefore, the transition growth of the granulation tissue of the fistulization external orifice often needs intervention of a surgical department or an ostomy engineer, which is one of the difficulties affecting the technical popularization.

The current clinically used gastrostomy replacement tubes are single in model and are of long tube structures, long tube bodies are required to be fixed on the abdomen or chest through adhesive tapes or ropes, and invisible functions are lacked, so that discomfort and physical aesthetic feeling of patients are greatly improved, and the gastrostomy replacement tubes become one of important factors which seriously disturb the participation of gastrostomy patients in social contact.

The internal fixing pad of the existing replacement tube is made of a rubber water sac, is not resistant to digestive juice corrosion, is easy to age and break, so that the replacement tube is embedded and falls off, a new replacement tube is needed to be replaced, the falling off time is longer than 6 hours, the replacement tube is difficult to be placed again, the nutrition in the fistulization stomach and intestine is failed, and the replacement tube is embedded and can cause serious complications such as abdominal wall necrosis; balloon aging and rupture also lead to short replacement cycle of the replacement tube, requiring multiple replacement of the replacement tube in a short time, resulting in poor patient compliance and increased economic burden for the patient; the balloon type internal fixing pad cannot adapt to physiological changes of radian of the stomach wall, has poor fitting degree, is easy to cause compression damage of the stomach wall and leakage of digestive tract liquid along a tube body, so that the infection of an external stoma is caused, the nursing difficulty is increased, and the nutrition failure in the stomach and intestine of the fistulization is caused by serious patients; and the catheter body of the gastrostomy replacement balloon catheter is long, and an auxiliary device is required to be fixed on the abdominal wall part, so that the hiding function cannot be realized, and the diversified living requirements of patients cannot be met.

To this end, an embodiment of the present utility model proposes a gastrostomy replacement device 1000, specifically referring to fig. 1 to 5 of the drawings of the specification.

Referring to fig. 1 and 2, a gastrostomy replacement device 1000 according to an embodiment of the present utility model, the gastrostomy replacement device 1000 includes a fistulation tube 100, an auxiliary member 200, and an outer sheath 300. Among them, the ostomy tube 100 includes a tube body 110, an inner fixing pad 120, and an outer fixing pad 130. It should be noted that, the inner fixing pad 120 is fixedly connected to one end of the tube 110, and the outer fixing pad 130 is fixedly connected to the other end of the tube 110. It should be further noted that, the inner fixing pad 120 can be contracted or expanded along the radial direction of the tube body 110, and the outer fixing pad 130 can be contracted or expanded along the radial direction of the tube body 110. Specifically, the inner fixing pad 120 is a nickel steel memory alloy mesh-type woven structure, and the outer fixing pad 130 is a nickel steel memory alloy mesh-type woven structure. Therefore, the inner fixing pad 120 and the outer fixing pad 130 can be deformed when an external force is applied, have strong plasticity, shrink when the external force is applied, and can be unfolded to an original state after the external force is lost.

Referring to fig. 3, it should be noted that the auxiliary member 200 is connected to an end of the tube 110 near the outer fixing pad 130. The outer sheath 300 is sleeved over the fistulization tube 100 and the auxiliary member 200 to shrink the inner and

outer fixing pads

120 and 130. That is, the outer sheath 300 restricts the expansion of the inner fixing pad 120, so that the inner fixing pad 120 is contracted; the outer sheath 300 restricts the expansion of the outer fixing pad 130, and contracts the outer fixing pad 130. It should be noted that the outer sheath 300 is capable of sliding along the axial direction of the ostomy tube 100 and the auxiliary member 200. After the outer sheath 300 is moved and detached from the ostomy tube 100, the inner fixing pad 120 is not constrained by the outer sheath 300 and is changed from the contracted state to the expanded state, and the outer fixing pad 130 is not constrained by the outer sheath 300 and is changed from the contracted state to the expanded state.

The replacement process of the gastrostomy replacement device 1000 includes the following steps: step one, the old ostomy tube 100 is removed. It will be appreciated that the new ostomy tube 100 is within the gastrostomy replacement device 1000. Step two, the gastrostomy replacement device 1000 is passed through the abdominal wall 3000 and the stomach wall 2000 of the patient. It should be noted that the outer sheath 300 is embodied to pass through the abdominal wall 3000 and the stomach wall 2000 of the patient. Step three, the auxiliary member 200 is fixed by hand. It will be appreciated that since the auxiliary element 200 is connected to the tube body 110, the fixing of the auxiliary element 200 by hand allows the tube body 110 to be fixed, i.e. the new ostomy tube 100 to be fixed. Step four, the outer sheath 300 is pulled. Specifically, the outer sheath 300 is pulled in the direction of the ostomy tube 100 to the aid 200 until the outer sheath 300 is completely detached from the ostomy tube 100.

In step four, as shown in fig. 1 and 2, the outer sheath 300 is first released from the restraint of the inner fixing pad 120 as the outer sheath 300 moves. At this time, the inner fixing pad 120 is first unfolded and is abutted against the inner side of the stomach wall 2000 of the patient. As shown in fig. 2 and 3, as the outer sheath 300 continues to move, the outer sheath 300 releases the constraint of the outer fixing pad 130. At this time, the external fixation pad 130 is spread out and is abutted against the outer side of the abdominal wall 3000 of the patient. With the cooperation of the inner and

outer fixing pads

120, 130, the new ostomy tube 100 is fixed to the patient's body, thereby achieving replacement of the ostomy tube 100.

After a certain period of time, when the ostomy tube 100 fixed to the patient needs to be replaced, the ostomy tube 100 may be pulled directly, and the inner fixing pad 120 may be automatically deformed when passing through the inner stoma of the stomach wall 2000, the fistula tract and the outer stoma of the abdominal wall 3000, which is a specific case of the first step.

It can be appreciated that the gastrostomy replacement device 1000 according to an embodiment of the present utility model does not require the steps of inflating as in the conventional device, and the replacement of the fistulization tube 100 can be rapidly performed by pulling the outer sheath 300, thereby reducing the time spent for the replacement of the fistulization tube 100, improving the working efficiency, and reducing the pain of the patient.
