Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of gastrostomy tubes, and in particular relates to a washable and detachable gastrostomy tube. Background Art
[0002] A gastrostomy tube is a medical device that can deliver liquid food directly to the stomach for patients who have lost the ability to actively eat. Currently, percutaneous endoscopic gastrostomy (PEG) is mainly used to place a gastrostomy tube. First, an endoscope is used to locate a suitable puncture point from the inside of the stomach. Then, a small incision is made on the abdomen corresponding to the puncture point, and the puncture needle is inserted into the stomach through the abdominal wall. Then, a guide wire is inserted into the stomach through the puncture needle, and the channel between the abdominal wall and the stomach wall is gradually expanded along the guide wire until the gastrostomy tube can be inserted. Finally, the channel is closed by the stomach stopper and the skin stopper on the gastrostomy tube. In this way, a gastrostomy tube is inserted into the stomach, and liquid food can be delivered through the part of the gastrostomy tube that remains outside the body.
[0003] Patients who have lost the ability to eat actively need to use a gastrostomy tube for a long time. A gastrostomy tube can be used for about two to three months. During this period, it is very important to maintain the part outside the tube, especially the cleaning of food remaining in the tube after each meal. The current gastrostomy tubes are not easy to wash out for some foods that are not very fluid, such as slightly thicker porridge, which remain in the gastrostomy tube. The unwashed part will be brought into the stomach during the next meal. Summary of the invention
[0004] The purpose of the present invention is to provide a washable and detachable gastrostomy tube, so as to solve the technical problem that food with poor fluidity is difficult to wash out after remaining in the gastrostomy tube.
[0005] In order to solve the above technical problems, the present invention provides a washable and detachable gastrostomy tube, comprising: a main tube, a one-way valve is provided inside the tube of the insertion end, and a stomach-side baffle is provided on the outer wall of the insertion end; an abdominal baffle is provided on the main tube separated from the stomach-side baffle to clamp the stomach wall and the abdominal wall together with the stomach-side baffle; a movable tube is provided in the main tube and is suitable for terminating the conduction with the one-way valve after the end of eating and moving outward until the conduction end with the one-way valve is located on the outside of the residual extrusion component on the main tube; a flushing tube is inserted in the main tube and is located on the outside of the food intake end of the movable tube when the conduction end of the movable tube is located on the outside of the residual extrusion component on the main tube; and a sleeve tube is suitable for being separated from the docking part of the abdominal outer end of the main tube through the sleeve joint and removed after the food intake end of the movable tube is flushed by the flushing tube.
[0006] Furthermore, a lever slot is provided on the outer wall of the main pipe, and a conducting positioning hole and a flushing positioning hole are respectively provided at both ends of the lever slot; a lever is provided on the movable pipe, and passes through the main pipe through the lever slot, so that when the movable pipe is pushed to the conducting positioning hole, the movable pipe and the one-way valve are fitted and connected, and when the movable pipe is pushed to the flushing positioning hole, the conducting end of the movable pipe is located on the outside of the residual extrusion assembly on the main pipe and the flushing pipe is located on the outside of the food feeding end of the movable pipe.
[0007] Furthermore, a food inlet is provided on the half of the movable tube located on the opposite side of the lever; and a hole blocking portion is provided on the half of the movable tube located on the same side of the lever.
[0008] Furthermore, an extrusion plane is cut on the outer wall of the main tube on the opposite side of the lever slot; the food inlet is an elliptical channel, and when the lever is inserted into the lever slot, the major axis of the cross section of the food inlet is parallel to the extrusion plane; the residual extrusion assembly includes: a pair of pressure rollers clamped on the main tube by rubber bands at both ends, so that when being rolled out, the movable tube is rolled along the extrusion plane from the conducting end of the movable tube to the food feeding end of the movable tube.

[0014] The beneficial effect of the present invention is that the present invention aims to solve the technical problem that food with poor fluidity is difficult to clean after remaining in a gastrostomy tube. The main tube of the easily washable detachable gastrostomy tube can be fixed on the patient's abdomen by clamping the stomach wall and the abdominal wall with a stomach side baffle and a ventral baffle. A movable active tube is arranged in the main tube, so that the one-way valve on one side of the stomach can be moved to fit with it during eating, so that food enters the one-way valve through the movable tube and enters the stomach, and no longer needs to enter the stomach through the difficult-to-clean main tube. After eating, the movable tube can be moved outward until the conducting end with the one-way valve is located on the outside of the residual extrusion component on the main tube, so that the residual food in the movable tube can be squeezed out by the residual extrusion component, and the residual extrusion component can be pressed to close the movable tube, so that the food intake end of the movable tube can be flushed with a flushing tube without worrying about entering the stomach, thereby achieving the cleaning of the part fixed to the patient's abdomen. The detachable sleeve can be directly removed for cleaning after the flushing is completed. Therefore, the gastrostomy tube achieves that the part fixed to the patient's abdomen has less food residue and is easy to clean, and the other part can be disassembled for cleaning.

[0025] Example
[0026] like Figure 1 As shown, the present invention provides a washable and detachable gastrostomy tube, comprising: a main tube 100, combined with Figure 2 and Figure 3 The tube at the insertion end is provided with a one-way valve 200, combined with Figure 2 The outer wall of the insertion end is provided with a stomach side baffle 310; the ventral baffle 320 is arranged on the main tube 100, and the stomach side baffle 310 is sandwiched with the stomach side baffle 310 to clamp the stomach wall and the abdominal wall; Figure 2 and Figure 3 The movable tube 400 is disposed in the main tube 100 and is adapted to terminate the connection with the one-way valve 200 and move outward after the meal is finished. Figure 2 , Figure 3 , Figure 4 The movable tube 400 is in a state of being connected to the one-way valve 200. Figure 5 As shown, until the conducting end with the one-way valve 200 is located outside the residual extrusion assembly 500 on the main pipe 100; after the movable pipe 400 can be moved to the outside of the residual extrusion assembly 500, the residual extrusion assembly 500 can be used to roll from the conducting end of the movable pipe 400 to the other end to squeeze out the residual food in the movable pipe 400; Figure 5, a flushing tube 600, which is inserted into the main tube 100 and is located outside the food intake end of the movable tube 400 when the conducting end of the movable tube 400 is located outside the residual extrusion assembly 500 on the main tube 100; by making the flushing tube 600 located outside the food intake end of the movable tube 400 when the conducting end of the movable tube 400 is located outside the residual extrusion assembly 500 on the main tube 100, the movable tube 400 can be pressed and closed, so that the flushing tube 600 can be used to flush the food intake end of the movable tube 400 without worrying about entering the stomach; a sleeve 700, which is suitable for being separated from the docking portion 110 of the abdominal outer end of the main tube 100 through the sleeve portion 710 and removed after the food intake end of the movable tube 400 is flushed by the flushing tube 600.
[0027] The main tube 100 of the washable detachable gastrostomy tube can be fixed on the patient's abdomen by clamping the stomach wall and the abdominal wall with the stomach side baffle 310 and the ventral side baffle 320. A movable active tube 400 is arranged in the main tube 100, so that it can be moved to the one-way valve 200 on one side of the stomach and fit with it when eating, so that food can enter the one-way valve 200 and the stomach through the movable tube 400, and no longer need to enter the stomach through the difficult-to-clean main tube 100. After eating, the movable tube 400 can be moved outward until the conducting end with the one-way valve 200 is located on the main tube 100. The outer side of the residual extrusion component 500 can be extruded by the residual extrusion component 500, and the residual extrusion component 500 can be pressed to close the movable tube 400, so that the food intake end of the movable tube 400 can be flushed with the flushing tube 600 without worrying about entering the stomach, thereby achieving the cleaning of the part fixed to the patient's abdomen, and the detachable sleeve 700 can be directly removed for cleaning after the flushing is completed. Therefore, the present gastrostomy tube achieves less food residue in the part fixed to the patient's abdomen and is easy to clean, and the other part is detachable for cleaning.
[0028] In at least one embodiment, the movable tube 400 is moved in the main tube 100 in the following manner. Figure 4 As shown, the outer wall of the main pipe 100 is provided with a lever slot 120, and the two ends of the lever slot 120 are respectively provided with a conducting positioning hole 130 and a flushing positioning hole 140; the movable pipe 400 is provided with a lever 410, Figure 3 , and passes through the lever slit 120 to pass through the main pipe 100, refer to Figure 2 , so that when the movable tube 400 is pushed to the conducting positioning hole 130, the movable tube 400 and the one-way valve 200 are in contact with each other, refer to Figure 5 When the flushing positioning hole 140 is moved, the conducting end of the movable tube 400 is located outside the residual extrusion assembly 500 on the main tube 100 and the flushing tube 600 is located outside the food intake end of the movable tube 400 .
[0029] like Figure 2 As shown, the half of the movable tube 400 located on the opposite side of the lever 410 is provided with a food inlet 420, and the half of the movable tube 400 located on the same side of the lever 410 is provided with a hole blocking portion 430. The hole blocking portion 430 is used to cover the lever slit 120 when the movable tube 400 and the one-way valve 200 are in contact with each other.
[0030] In at least one embodiment, in order to squeeze out the residual food from the active tube 400, as shown in FIG. Figure 1 As shown, the outer wall of the main pipe 100 on the opposite side of the lever slot 120 is cut with an extrusion plane 150; Figure 2 The food inlet 420 is an elliptical channel, and when the lever 410 is inserted into the lever slot 120, the long axis of the cross section of the food inlet 420 is parallel to the extrusion plane 150; the residual extrusion assembly 500 may include: a pair of rollers 520 clamped on the main tube 100 by rubber bands 510 at both ends, so as to roll the movable tube 400 along the extrusion plane 150 from the conducting end of the movable tube 400 to the food inlet end of the movable tube 400 when being rolled out. After the residual extrusion assembly 500 is set, the rubber band 510 can be opened when eating.
[0031] In order to prevent the rubber band 510 from slipping out, Figure 1 As shown, both ends of the pressing roller 520 may be provided with rubber band receiving grooves 521 .
[0032] like Figure 3 As shown, the docking portion 110 is a conical ring protrusion; the sleeve portion 710 is a leather ring adapted to the conical ring protrusion, so that the sleeve 700 is sleeved on the main pipe 100 to inject food into the main pipe 100 through the sleeve 700.
[0033] like Figure 2 As shown, the flushing tube 600 is shorter than the conical ring protrusion. The shorter flushing tube 600 can allow the harder cleaning syringe to be fully inserted, thereby utilizing the certain elasticity of the main pipe 100 and the flushing tube 600 to allow the flushing tube 600 to rotate in a small range, thereby flushing while rotating the angle, and achieving a better flushing effect.
[0034] like Figure 1 and Figure 2 As shown, the other end of the sleeve 700 may be sleeved with an elastic joint ring 720 to connect with, for example, a food injection cylinder.
[0035] like Figure 6As shown, the stomach side baffle 310 is provided with a memory alloy sheet 311, and the memory alloy sheet 311 penetrates into the tube wall of the main tube 100. By providing the memory alloy sheet 311, the stomach side baffle 310 can be folded toward the axial direction of the main tube 100 before being inserted into the stomach, so that after passing through the fistula hole and entering the stomach to increase in temperature, the stomach side baffle 310 is turned outward, so that the ventral baffle 320 clamps the stomach wall and the abdominal wall. When it needs to be removed, it is only necessary to insert a pre-cooled tube into the one-way valve 200 to cool the memory alloy sheet 311 near the one-way valve 200.
[0036] In summary, the main tube 100 of the washable detachable gastrostomy tube can be fixed on the patient's abdomen by clamping the stomach wall and the abdominal wall with the stomach side baffle 310 and the ventral baffle 320. A movable active tube 400 is arranged in the main tube 100, so that it can be moved to the one-way valve 200 on one side of the stomach and fit therewith during eating, so that food can enter the one-way valve 200 and the stomach through the movable tube 400, and no longer needs to enter the stomach through the difficult-to-clean main tube 100. After eating, the movable tube 400 can be moved outward until the conducting end with the one-way valve 200 is located at the main tube 10 0, so that the residual extrusion component 500 can be used to squeeze out the residual food in the movable tube 400, and the residual extrusion component 500 can be pressed to close the movable tube 400, so that the food intake end of the movable tube 400 can be flushed with the flushing tube 600 without worrying about entering the stomach, thereby achieving the cleaning of the part fixed to the patient's abdomen, and the detachable sleeve 700 can be directly removed for cleaning after the flushing is completed. Therefore, the present gastrostomy tube achieves less food residue in the part fixed to the patient's abdomen and is easy to clean, and the other part is detachable for cleaning.
