[0002] In clinical work, patients are unable to eat due to obstructions caused by tumors such as esophageal cancer, hypopharyngeal cancer, oral cancer, and pain caused by radiotherapy for hypopharyngeal cancer. In the above cases, gastrostomy is required to improve the nutritional status of patients and improve their quality of life. In clinical practice, there are two forms of endoscopic percutaneous gastrostomy. One is the pull-in type, which is only suitable for situations where there is no stenosis or obstruction from the mouth to the stomach. It is currently produced by Cook Company in the United States. The mushroom head under the fistula tube prevents slipping. The other is the insertion type, which is more widely applicable and can be used in the above-mentioned situations that are not applicable, such as esophageal stenosis caused by esophageal cancer. This type of fistula tube is produced by Japan Kukuliate Medical Co., Ltd., and the water-filled balloon under the fistula tube prevents slipping.

[0003] Chinese patent publication number CN215740571U discloses a similar visualized gastrointestinal fistula tube, including a tube body and an abdominal wall fixing device, the tube body includes a stomach tube and an intestinal tube, the stomach tube and the intestinal tube are fixedly connected, the abdominal wall fixing device is located on the outside of the stomach tube and the intestinal tube, the abdominal wall fixing device includes an air bag and an air injection tube, the air bag is fixed on the outside of the tube body, one end of the air injection tube is connected to the air bag, a guide wire is arranged in the intestinal tube, a visual lens is arranged at the front end of the guide wire, and the other end of the guide wire is connected to a display.

[0004] The above device is an insertable gastrointestinal fistula tube, and an air bag is used under the fistula tube to prevent slipping. However, during clinical use, the gastrointestinal fistula tube is prone to slipping due to rupture or leakage of the air bag, which requires re-insertion of the tube, causing discomfort to the patient. Utility Model Content

[0005] The utility model aims to overcome the problem of an insertable gastrointestinal fistula tube in the prior art. An air bag is used under the fistula tube to prevent it from slipping off. However, during clinical use, the gastrointestinal fistula tube is prone to slipping off due to rupture or leakage of the air bag, and the tube needs to be inserted again, causing discomfort to the patient.

[0006] A novel anti-slip gastrostomy tube is proposed, comprising a gastric tube for diversion, an annular baffle for fixing the gastric tube, a tee for connection, an esophageal injection tube for injecting liquid food, an injection tube for injecting water into a water bag assembly, a rotating shunting device for shunting, a water bag assembly for preventing slippage, and an imaging device for imaging the internal situation of the water bag assembly. The annular baffle is sleeved on the middle section of the gastric tube, one end of the gastric tube is connected to a lateral interface at one end of the tee, the lateral interface at the other end of the tee is connected to the esophageal injection tube, the middle section interface of the tee is connected to the injection tube, one end of the injection tube is connected to the tee, and the other end of the injection tube is connected to the rotating shunting device. There are two groups of water bag assemblies, which are sleeved on the gastric tube in parallel and are both located at the other end of the gastric tube, and the two groups of water bag assemblies are connected to the rotating shunting device by pipes. The imaging device is arranged inside the water bag assembly and connected to the injection tube by pipes.

[0007] In the technical solution of the utility model, after the gastric tube is placed into the human body during use, the physiological saline is again introduced into the first balloon through the injection tube and the rotating water distribution device through the guide tube. After the first balloon is fully expanded, the physiological saline inside the first balloon will be introduced into the second balloon through the second membrane valve. After the physiological saline enters the second balloon, the second balloon will begin to expand and begin to squeeze the pressure sensor on the film. After the value provided by the pressure sensor reaches the standard, the introduction of physiological saline into the first and second balloons can be stopped. The second balloon and the first balloon can automatically recover after the external force ends. Therefore, when the second balloon is squeezed or the physiological saline inside the second balloon is squeezed out due to other factors, the physiological saline inside the second balloon Water will enter the first balloon through the second membrane valve, and after the pressure outside the second balloon or external factors disappear, the second balloon will absorb the physiological saline inside the first balloon into the second balloon through the second valve while starting to restore its original shape, until the water content inside the second balloon reaches the original level. Two groups of water balloon assemblies are arranged on the gastric tube. Therefore, when one group of water balloon assemblies is damaged or leaking, water can be injected into the other group of water balloon assemblies through a rotating diversion device to avoid slipping of the gastric tube. This is used to solve the problem of insertable gastrointestinal fistula tubes mentioned in the technical background. An air bag is used under the fistula tube to prevent slipping. However, during clinical use, gastrointestinal fistula tubes are prone to slipping due to air bag rupture or leakage, and the tube needs to be inserted again, causing discomfort to the patient.

[0008] Preferably, the other end of the feeding tube is provided with a plug. When liquid food needs to be provided to the patient, the plug can be opened and liquid food can be provided to the patient through the feeding tube. After the meal is finished, the plug can be put into the feeding tube to prevent external dust and other impurities from contaminating the inner wall of the feeding tube.

[0009] Preferably, the annular baffle is provided with a plurality of through holes, and is used to fix the position of the gastric tube. Moreover, because the annular baffle is mounted on the gastric tube through a notch on one side, it can be removed and cleaned after use for next use.

[0010] Preferably, the rotary flow diversion device comprises a rotary switch, a connecting pipe, a liquid dispensing head, a sealing plate, a first liquid dispensing tube, a second liquid dispensing tube, a guide tube and a first membrane flap, one end of the rotary switch is connected to the connecting pipe, the other end of the rotary switch is rotatably connected to the inside of the liquid dispensing head, the sealing plate is laterally fixedly connected to the inside of the liquid dispensing head, a rotary switch is provided at one end of the sealing plate, the other end of the sealing plate is connected to the first liquid dispensing tube and the second liquid dispensing tube, the first liquid dispensing tube and the second liquid dispensing tube are evenly arranged at one end of the sealing plate with the axis of the sealing plate as the center, and are connected in the length direction of the liquid dispensing head. It is connected to the sealing plate, and the first dispensing tube and the second dispensing tube are both connected to one end of a guide tube at their water outlets, the other end of the guide tube is connected to the first membrane flap and the tube body that passes through the gastric tube is arranged inside the first balloon of the water bag assembly, there are two groups of water bag assemblies, and the rotating diversion device can inject water into the two groups of water bag assemblies. Therefore, when one group of water bag assemblies on the gastric tube is damaged and causes leakage, the rotary switch can be rotated inside the dispensing head to inject water into the other group of water bag assemblies through the rotary switch, so as to avoid the situation where the patient must be catheterized after the water bag assembly is damaged, thereby alleviating the patient's discomfort.

[0011] Preferably, the sealing plate is provided with a plurality of groups of through holes, and each group of through holes on the sealing plate is respectively connected to a first dispensing tube and a second dispensing tube. Therefore, when necessary, the through holes on the rotary switch can be aligned with the through holes on the sealing plate, and then physiological saline can be respectively input into the two groups of water bag assemblies through the through holes on the sealing plate.

[0012] The preferred technical solution of the utility model is that the water balloon assembly includes a fixing ring, a second membrane flap, a first balloon, a second balloon and a covering film, the fixing ring is sleeved above the gastric tube, the second membrane flap has two groups and is symmetrically arranged on both sides of the gastric tube with the axis of the gastric tube as the center, and the two groups of second membrane flaps are connected to the fixing ring in the length direction of the gastric tube, the first balloon is sleeved on the gastric tube and connected to one end of the fixing ring, the second balloon is also sleeved on the gastric tube and connected to the other end of the fixing ring, and a camera and a light source of an imaging device are arranged inside the second balloon, one end of the second membrane flap is connected to the inside of the first balloon, and the other end of the second membrane flap is connected Inside the second balloon, the coating sleeve is arranged on the gastric tube and covers the outside of the first balloon, the fixing ring and the second balloon. Because the second balloon and the first balloon are both elastic, when the second balloon is deformed, the physiological saline inside the second balloon will enter the first balloon. After the pressure outside the second balloon or external factors disappear, the second balloon will absorb the physiological saline inside the first balloon into the second balloon through the second valve in the process of recovering its original shape until the water content inside the second balloon reaches the original level. The volume inside the first balloon is 0.3ML, and the volume inside the second balloon is 0-5ML.

[0013] In a preferred embodiment of the technical solution of the utility model, a pressure sensor is further provided inside the coating, and the pressure sensor is electrically connected to the display of the imaging device. The pressure sensor is arranged inside the coating and is located on one side of the second balloon, and the pressure sensor is connected to the coating. Therefore, when physiological saline enters the interior of the second balloon and causes the water balloon to expand, the water balloon will squeeze the pressure sensor. Therefore, the pressure sensor will always detect the pressure inside the second balloon. When the pressure inside the second balloon drops below the critical value, the medical staff will be reminded through the display.

[0014] Preferably, the imaging device includes a display, a hose, a first guide wire, a second guide wire, a camera and a light source. The display is arranged on one side of the gastric tube, one end of the hose is connected to the infusion tube, and the other end of the hose is connected to the display. One end of the first guide wire and the second guide wire are arranged inside the hose and electrically connected to the display.

The ends of the first guide wire and the second guide wire located inside the second balloon are both provided with cameras and light sources. The cameras are mounted on the first guide wire and the second guide wire, and the light source is fixedly connected to the ends of the first guide wire and the second guide wire.

[0015] Preferably, the light source is a light emitting diode (LED), which has relatively low power consumption and long service life, high brightness and uniform light, and can well assist the camera in imaging when needed.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. Two groups of water balloon assemblies are arranged on the gastric tube, and each group of water balloon assemblies is provided with a first balloon and a second balloon, and the volume of the second balloon is larger than that of the first balloon. After the second balloon is fully expanded by being injected with saline, it can clamp the gastric tube to prevent it from slipping off. After one group of water balloon assemblies is broken, saline can be injected into the other group of water balloon assemblies through a rotating shunt device, so that the water balloon assemblies can replace the broken water balloon assemblies to continue to clamp the position of the gastric tube to prevent it from slipping off, thereby avoiding secondary catheterization;

[0018] 2. Both the first balloon and the second balloon are made of elastic material and will return to their original shape after the force is applied. Therefore, after the second balloon is deformed by the force, the saline inside the second balloon will enter the first balloon and be temporarily stored. At this time, the first balloon will also be deformed. After the force is applied to the second balloon, the second balloon will absorb the saline squeezed into the first balloon back into the second balloon in the process of recovering its original shape. In addition, the first balloon will also squeeze the saline into the second balloon in the process of recovering its original shape, thereby reducing the risk of rupture of the second balloon.

DETAILED DESCRIPTION

[0030] The following will be combined with the attached embodiment of the utility model Figure 1-10 , the technical solutions in the embodiments of the utility model are described in detail.

[0031] like Figure 1 As shown, a novel anti-slip gastrostomy tube comprises a gastric tube 1 and an annular baffle 2 for fixing the gastric tube 1, the annular baffle 2 is sleeved on the middle section of the gastric tube 1 and can be adjusted up and down according to the length direction of the gastric tube 1 according to the use requirements, a plurality of through holes are arranged on the annular baffle 2, and after the gastric tube 1 is used, the annular baffle 2 can be removed from the gastric tube 1 and then cleaned, a tee 3 is located at one end of the gastric tube 1, and one end of the gastric tube 1 is connected to a transverse interface at one end of the tee 3, and an injection tube 4 is connected to the transverse interface at the other end of the tee 3, after the gastric tube 1 is placed in the patient's body and the patient needs to eat, liquid food can be provided to the patient through the injection tube 4, one end of the injection tube 4 is connected to the tee 3, and a plug 41 is arranged at the other end of the tee 3, and the plug 41 is sleeved on the injection tube 4.

[0032] like Figure 1As shown, when providing liquid food to the patient through the esophageal tube 4, the plug 41 can be taken out of the esophageal tube 4, and after the patient finishes eating, the plug 41 can be put into the esophageal tube 4 again to prevent the external environment from contaminating the esophageal tube 4. The oblique interface of the tee 3 is connected with an injection tube 5, one end of the injection tube 5 is connected to the tee 3, and the other end of the injection tube 5 is connected to a rotating diverter device 6. The rotating diverter device 6 and the two groups of water bag components 7 set on the gastric tube 1 are connected by pipelines, and the rotating diverter device 6 is connected to the two groups of water bag components 7 set on the gastric tube 1. Water can be supplied to one group of water bag assemblies 7 at a time. Therefore, if one group of the two groups of water bag assemblies 7 is damaged and leaks and cannot prevent the gastric tube 1 from slipping off, water can be supplied to the other group of water bag assemblies 7 through the rotating diversion device 6 to avoid the gastric tube 1 from slipping off and the patient needing to have the tube inserted again, thereby alleviating the patient's discomfort. There are two groups of water bag assemblies 7, both of which are mounted on the gastric tube 1. The tee 3 is located at one end of the annular baffle 2, and the two groups of water bag assemblies 7 are located at the other end of the annular baffle 2, and the two groups of water bag assemblies 7 are adjacent to each other.

[0033] like Figure 2-3 As shown, the imaging device 8 includes a display 81, a hose 82, a first guide wire 83, a second guide wire 84, a camera 85 and a light source 86. The display 81 is located on one side of the stomach tube 1, and the display 81 is connected to the injection tube 5 by the hose 82. The inside of the hose 82 is also provided with one end of the first guide wire 83 and the second guide wire 84, and the first guide wire 83 and the second guide wire 84 are both electrically connected to the display 81. The other ends of the first guide wire 83 and the second guide wire 84 are located inside the stomach tube 1, and the first guide wire 83 and the second guide wire 84 pass through the tube body of the stomach tube 1 and are connected to the water bag assembly 7. The first guide wire 83 and the second guide wire 84 used in the second water bag are both optical fiber guide wires, so the first guide wire 83 and the second guide wire 84 are easy to retain and can be removed for reuse, and the ends of the first guide wire 83 and the second guide wire 84 located in the second water bag of the two groups of water bag assemblies 7 are provided with cameras 85 and light sources 86. The light source 86 used is a light emitting diode, which has relatively low power consumption, long service life, high brightness and uniform light, so it can well help the camera 85 to image when the camera 85 needs to image.

[0034] like Figure 2-3As shown, when the pressure sensor 9 located inside the water bag assembly 7 detects that the pressure inside the first water bag decreases, the situation inside the second water bag can be imaged by the camera 85, and the image can be transmitted to the display 81 through the first guide wire 83 and the second guide wire 84. When the camera 85 is imaging, the light source 86 will emit light to illuminate the inside of the second water bag. After the medical staff finds that the physiological saline inside the second water bag is turbid or the color turns red through the display 81 to determine that the second water bag has been damaged, the physiological saline can be input into the second water bag of the other group of water bag assemblies 7 through the rotating diversion device 6 to make it expand to prevent the gastric tube 1 from slipping. Two guide tubes 67 are also provided inside the three-way tube 3, one end of the guide tube 67 is connected to the first liquid dispensing tube 65 and the second liquid dispensing tube 66 of the rotating diversion device 6, and the other ends of the two guide tubes 67 are arranged inside the gastric tube 1 and both pass through the tube body of the gastric tube 1 and are respectively connected to the inside of the first balloon 73 of the two groups of water bag assemblies 7.

[0035] like Figure 4-7 As shown, the rotary diversion device 6 includes a rotary switch 61, a connecting pipe 62, a liquid dispensing head 63, a sealing plate 64, a first liquid dispensing tube 65, a second liquid dispensing tube 66, a guide tube 67 and a first membrane flap 68. The connecting pipe 62 is connected to one end of the rotary switch 61. When the rotary diversion device 6 is used, physiological saline can be input into the rotary switch 61 through the connecting pipe 62. The other end of the rotary switch 61 is rotatably connected to the inside of the liquid dispensing head 63, so that the rotary switch 61 can be manually driven to rotate when necessary, and a group of through holes are provided at the bottom of the rotary switch, the sealing plate 64 is transversely arranged inside the liquid dispensing head 63, and two groups of through holes are provided on the sealing plate 64, the first liquid dispensing tube 65 and the second liquid dispensing tube 66 are both arranged inside the liquid dispensing head 63, the rotary switch 61 is provided at one end of the sealing plate 64, the first liquid dispensing tube 65 and the second liquid dispensing tube 66 are provided at the other end of the sealing plate 64, and the first liquid dispensing tube 65 and the second liquid dispensing tube 66 are both connected to the through holes on the sealing plate 64 along the length direction of the liquid dispensing head 63.

[0036] like Figure 4-7As shown, the first dispensing tube 65 and the second dispensing tube 66 are both connected with a guide tube 67, one end of the guide tube 67 is connected with the first dispensing tube 65 and the second dispensing tube 66 of the rotating diverting device 6, and the other end of the guide tube 67 is arranged inside the stomach tube 1 and passes through the tube body of the stomach tube 1 to be respectively connected to the inside of the first balloon 73 of the two groups of water bag assemblies 7, and the end of the guide tube 67 located inside the first balloon 73 is provided with a first membrane flap 68, so when the physiological saline is input into the inside of the first balloon 73 through the guide tube 67, the first membrane flap 68 will open to allow the physiological saline to enter the inside of the first balloon 73, and after the physiological saline is input, the first membrane flap 68 will automatically close to prevent the physiological saline inside the first balloon 73 from flowing back into the inside of the guide tube 67, causing insufficient water content inside the first balloon 73, and then causing the physiological saline inside the first balloon 73 to be unable to enter the inside of the second balloon 74.

[0037] like Figure 4-7 As shown, when the rotary diversion device 6 is used to input physiological saline into the water bag assembly 7, the rotary switch 61 can be manually driven to rotate so that the through hole on the rotary switch 61 is aligned with the through hole on the sealing plate 64 located at the first liquid dispensing tube 65, and then the physiological saline is injected into the rotary switch 61 through the connecting pipe 62. The physiological saline will then enter the interior of the guide tube 67 through the first diversion tube, and after being guided by the guide tube 67, the physiological saline will open the first membrane flap 68 and enter the interior of the first balloon 73. After the first balloon 73 is filled and expanded, the physiological saline will open the second membrane flap 72 and enter the interior of the second balloon 74. After the second balloon 74 is filled and expanded, and the pressure sensor 9 also shows that the pressure of the second balloon 74 reaches the standard, the injection of water into the first balloon 73 can be stopped.

[0038] like Figure 4-7 As shown, after the pressure sensor 9 detects that the pressure inside the first balloon 73 drops below the critical value, and then determines through the imaging device 8 that the second balloon 74 is damaged and leaking, the rotary switch 61 can be manually driven to rotate again, so that the through hole on the rotary switch 61 is aligned with the through hole located at the second dispensing tube 66 on the sealing plate 64, and then physiological saline is again input into the first balloon 73 of another group of water balloon components 7 through the second dispensing tube 66 and the guide tube 67 to expand it, and the physiological saline is again input into the second balloon 74 through the second membrane flap 72 to expand it, so as to replace the damaged water balloon component 7 to prevent the gastric tube 1 from slipping, and avoid the situation where the patient must be catheterized after one group of water balloon components 7 is damaged, thereby alleviating the patient's discomfort.

[0039] like Figure 8-10As shown, the water balloon assembly 7 includes a fixing ring 71, a second membrane flap 72, a first balloon 73, a second balloon 74 and a coating 75. The volume inside the first balloon 73 is 0-3 ml, and the volume inside the second balloon 74 is 0-5 ml. The fixing ring 71 is sleeved on the gastric tube 1. There are two groups of second membrane flaps 72, which are symmetrically arranged on both sides of the gastric tube 1 with the axis of the gastric tube 1 as the center, and the two groups of second membrane flaps 72 are connected to the fixing ring 71 according to the length direction of the gastric tube 1. The water inlet of the second membrane flap 72 is arranged inside the first balloon 73 through the fixing ring 71, and the water outlet of the second membrane flap 72 is arranged inside the second balloon 74 through the fixing ring 71. The first balloon 73 is sleeved on the gastric tube 1 and is located at one end of the fixing ring 71, and the first balloon 73 is connected to the fixing ring 71. The second balloon 74 is also sleeved on the gastric tube 1 and is located at the other end of the fixing ring 71, and the first balloon 73 is also connected to the fixing ring 71.

[0040] like Figure 8-10 As shown, the first balloon 73 and the second balloon 74 are both made of elastic material and can return to their original state after the external force ends. One end of the guide tube 67 and the first membrane flap 68 are provided inside the first balloon 73, so that the physiological saline will enter the first balloon 73 through the guide tube 67 and the first membrane flap 68, allowing the first balloon 73 to fully expand, and then the guide tube 67 will continue to input physiological saline into the first balloon 73 until the pressure of the physiological saline inside the first balloon 73 is greater than the resistance of the second membrane flap 72, and then the first balloon 73 is expanded. The normal saline can enter the interior of the second balloon 74 through the second membrane valve 72 until the second balloon 74 is fully expanded. After the pressure sensor 9 measures that the pressure inside the second balloon 74 has reached the critical value, the input of normal saline into the first balloon 73 can be stopped. When the input of normal saline into the first balloon 73 is stopped, the rotary switch 61 can be manually driven to rotate. The bottom of the rotary switch 61 will block the through hole on the sealing plate 64 to prevent the normal saline inside the guide tube 67 from flowing back into the interior of the dispensing head 63.

[0041] like Figure 8-10As shown, when the physiological saline stops being input into the first balloon 73, the first membrane flap 68 will also be closed to prevent the physiological saline in the first balloon 73 from flowing back into the interior of the guide tube 67. At this time, the second balloon 74 is fully expanded, so the second balloon 74 can prevent the gastric tube 1 from slipping. When the second balloon 74 is squeezed or under the influence of other external factors, causing the volume of the second balloon 74 to shrink, the physiological saline in the second balloon 74 will enter the interior of the first balloon 73 through the second membrane flap 72. However, at this time, the first membrane flap 68 has been closed, and there is still physiological saline in the interior of the guide tube 67, and the sealing plate 64 has sealed all the through holes on the sealing plate 64. Therefore, when the physiological saline in the second balloon 74 enters the interior of the first balloon 73, the first balloon 73 will continue to expand and deform, and the volume of the first balloon 73 will gradually increase.

[0042] like Figure 8-10 As shown, when the pressure outside the first balloon 73 disappears, the second balloon 74 will restore its original shape and absorb the saline originally discharged into the first balloon 73 back into the second balloon 74. At this time, the first balloon 73 will also restore to its original shape, and press the second balloon 74 into the saline inside the first balloon 73 and press it back into the second balloon 74 again until the second balloon 74 restores its original shape and clamps the gastric tube 1 again to prevent the gastric tube 1 from slipping off, thereby reducing the risk of the second balloon 74 rupturing due to the inability to discharge the saline inside the second balloon 74 when the second balloon 74 is squeezed. When the saline inside the second balloon 74 is lost, the saline inside the first balloon 73 will enter the second balloon 74 through the second membrane flap 72, allowing the second balloon 74 to remain inflated as much as possible, so that the second balloon 74 can clamp the gastric tube 1 to prevent it from slipping off.

[0043] like Figure 8-10 As shown, the coating 75 is also sleeved on the gastric tube 1 and covers the first balloon 73, the fixing ring 71 and the second balloon 74. A pressure sensor 9 is also arranged inside the coating 75. The pressure sensor 9 is located on one side of the second balloon 74 and is also electrically connected to the display 81 of the imaging assembly. Therefore, when the physiological saline enters the second balloon 74 to expand and deform the second balloon 74, the second balloon 74 will begin to squeeze the pressure sensor 9, and the pressure sensor 9 will also cause the second balloon 74 to produce The generated pressure is transmitted back to the display 81. After the medical staff learns through the display 81 that the pressure inside the second balloon 74 has reached the critical value, they will stop inputting saline into the first balloon 73. Similarly, when the second balloon 74 is damaged, the pressure sensor 9 will detect that the pressure of the second balloon 74 has decreased and fallen below the critical value. It will then remind the medical staff through the display 81 and help the medical staff together with the imaging device 8 to determine whether to inject water into the second water bag of the other water bag assembly 7 to allow it to jam the gastric tube 1 and prevent the gastric tube 1 from slipping.

[0044] The movement process of this embodiment is as follows: after the gastric tube 1 is placed inside the patient's body, the rotary switch 61 of the rotary diversion device 6 is manually driven to rotate until the through hole at the bottom of the rotary switch 61 is aligned with the through hole on the first liquid dispensing tube 65 on the sealing plate 64, and then physiological saline is injected into the rotary switch 61 through the connecting pipe 62, and then the physiological saline flows into the first balloon 73 through the guiding tube 67. After the first balloon 73 is fully expanded, the physiological saline enters the second balloon 74 through the second membrane flap 72 until the second balloon 74 is fully expanded. After the second balloon 74 is fully expanded, it will begin to clamp the gastric tube 1 to prevent the gastric tube 1 from slipping. When the second balloon 74 is expanded, the pressure sensor 9 will monitor the pressure value of the second balloon 74 at all times, and then transmit it to the display 81 of the imaging device 8. After the medical staff finds that the pressure inside the second balloon 74 reaches the standard through the display 81, the injection of physiological saline into the rotary joint will be stopped, and then the rotary switch 61 will be manually driven to rotate again to seal the through hole on the sealing plate 64 at the first liquid dispensing tube 65.

[0045] When the pressure detector detects that the pressure inside the second balloon 74 decreases and is about to fall below the critical value, an alarm will be immediately issued through the display 81, and then the medical staff will image the inside of the second balloon 74 through the camera 85 of the imaging device 8. Under the illumination of the light source 86, when the medical staff finds that the physiological saline inside the second balloon 74 becomes turbid or turns red, they will manually drive the rotary switch 61 to rotate again, align the through hole on the rotary switch 61 with the through hole on the sealing plate 64 located at the second dispensing tube 66, and then inject physiological saline into the rotary switch 61 again through the connecting pipe 62. The physiological saline is guided into the first balloon 73 and the second balloon 74 inside the other group of water balloon components 7 through the guide tube 67 and makes them fully inflated, so that it replaces the damaged water balloon component 7 to clamp the gastric tube 1, prevent the gastric tube 1 from slipping, and avoid the patient from needing to have the tube inserted again.

Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
