[0008] As a further solution of the present invention, the introduction component includes an introduction pipe, one horizontal end of the introduction pipe is connected to the end of the connecting pipe, the inner wall of the introduction pipe is provided with several groups of rubber columns, and pipe sleeves are fixed between the several groups of rubber columns. The pipe sleeve passes through the introduction pipe, the suction pipe is sleeved in the pipe sleeve, and an anti-slip sleeve is connected between the suction pipe and the pipe sleeve. The anti-slip sleeve is fixed at the horizontal end of the introduction pipe, the connecting pipe is connected to the cavity between the introduction pipe and the pipe sleeve, and the bottom end of the introduction pipe is fixed to the flushing head.

[0009] As a further solution of the present invention, the flushing head is designed in an inverted cone shape, and a plurality of spray holes are inclined outward and equidistantly arranged outside the flushing head, and the outer wall of the suction nozzle is designed in an arc surface.

[0010] As a further solution of the present invention, the limiting assembly includes a pressing sheet, which is arc-shaped and has medical adhesive tapes on both sides of the inner wall. A fixing sleeve is fixed to the outer side of the pressing sheet, an airbag ring is fixed inside the fixing sleeve, an anti-slip strip is provided inside the airbag ring, the introduction tube passes through the airbag ring and contacts the inner side of the anti-slip strip, a protective sleeve is fixed to the inner side of the pressing sheet, and the introduction tube is arranged inside the protective sleeve.

[0011] A method for using a gastric lavage nursing device in a gastroenterology department, the method comprising the following steps: During gastric lavage care, the introduction tube is inserted into the stomach from the patient's mouth, and then the limiting component is brought into contact with the patient's mouth skin. The two medical adhesive stickers on the inner side of the limiting component can adhere the arc-shaped pressing piece to the mouth, and at the same time, the teeth of the upper and lower jaws in the mouth can overlap the outside of the protective sleeve. The protective sleeve can prevent the teeth from directly contacting the introduction tube, thereby affecting the normal conduction work, thereby improving the safety of the introduction tube. Because the introduction tube passes through the airbag ring and contacts the inner side of the anti-slip strip, it can prevent the introduction tube from freely expanding and contracting in the body. When adjusting the length of the introduction tube extending out of the body, the introduction tube can be held and the introduction tube can be pushed or pulled at the opening of the fixed sleeve to adjust the length of the introduction tube extending into the body. With the setting of the anti-slip strip, the gap between the fixed sleeve and the introduction tube can be sealed, and the inside of the mouth can be isolated from the outside world. After the introduction tube drives the inverted cone-shaped flushing head into the stomach, the position of the suction nozzle at the end of the suction tube is adjusted, the suction tube is held and the inside of the introduction tube is moved so that the suction tube slides inside the tube sleeve through the anti-slip sleeve. During this process, the suction tube drives the suction nozzle at the bottom to extend under the stomach to facilitate the extraction of gastric liquid. When the suction tube is not under force, the anti-slip sleeve can limit it to prevent the suction tube from freely expanding and contracting and affecting the extraction work. Because the tube sleeve is fixed to the inner wall of the introduction tube by multiple rubber columns, the rubber columns play a supporting role between the introduction tube and the tube sleeve, preventing the esophagus from pressing the introduction tube to cause the cavity between the introduction tube and the tube sleeve to be closed, thereby ensuring the stability of the circulation of the cleaning liquid inside the cavity. Moreover, the rubber column is flexible in design and has a buffering effect, which prevents the esophagus from being in hard contact with the introduction tube and causing damage to the inner wall of the esophagus. When the stomach is being cleaned, the motor is controlled to drive the half gear to rotate clockwise, so that the half gear drives the sliding frame to move to the right through the upper teeth in the sliding frame, and the sliding frame drives the piston plate to move to the right through the support rod. During the movement of the left piston plate to the right, negative pressure is generated inside the turnover box on the left, so that cleaning liquid can be extracted from the cleaning liquid storage tank through the one-way valve 1 and the liquid extraction pipe. The one-way valve 1 can guide the cleaning liquid into the left turnover box, and the one-way valve 2 can prevent the external medium from flowing into the left turnover box. When the work of extracting the cleaning liquid is completed, the half gear drives the sliding frame through the lower teeth in the sliding frame. The sliding frame is driven to move to the left, so that the sliding frame drives the piston plate to move to the left through the support rod, so that the piston plate can squeeze the cleaning liquid in the left turnover box. The liquid inside the turnover box will not flow into the liquid extraction tube through the one-way valve 1, and the cleaning liquid will flow into the connecting pipe through the one-way valve 2. The cleaning liquid in the connecting pipe enters the cavity between the introduction pipe and the pipe sleeve. The cleaning liquid in the cavity enters the flushing head and is sprayed toward the stomach from the external spray holes. Because the multiple spray holes are inclined outward and equidistantly arranged outside the flushing head, the flushing range of the cleaning liquid on the stomach can be expanded, thereby achieving the purpose of multi-directional flushing of the stomach; The stomach is flushed with flushing fluid, and the resulting solute will fall into the bottom layer of the stomach and come into contact with the suction nozzle. The right piston plate can suck the solute through the one-way valve three, the suction tube and the suction nozzle during the movement to the left, so that the solute enters the right turnover box. The one-way valve three can prevent the solute inside the turnover box from flowing back to the suction tube, thereby preventing the solute from flowing back to the stomach. The one-way valve four can block the external medium from entering the right turnover box. During the movement of the right piston plate to the right, the piston plate can squeeze the solute so that it passes through the one-way valve four and the collection tube into the collection box, thereby facilitating the collection and processing of the solute, and the gas generated inside the collection box is discharged from the exhaust valve. Therefore, the solute in the stomach can be extracted in time while flushing the stomach, so that a large amount of solute will not accumulate in the stomach.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention cleans and cares the stomach, the half gear drives the sliding frame to move to the right through the teeth at the top of the sliding frame, and the sliding frame drives the piston plate to move to the right through the support rod, and can extract cleaning liquid from the cleaning liquid storage tank through the one-way valve 1 and the liquid extraction pipe. After completing the work of extracting the cleaning liquid, the half gear drives the sliding frame to move to the left through the teeth at the bottom of the sliding frame, so that the sliding frame drives the piston plate to move to the left through the support rod, so that the piston plate can squeeze the cleaning liquid in the left turnover box, and the cleaning liquid will flow into the connecting pipe through the one-way valve 2, and the cleaning liquid in the connecting pipe will enter the cavity between the inlet pipe and the pipe sleeve. The cleaning liquid in the cavity enters the flushing head and is sprayed toward the stomach from the external spray holes. Because the multiple spray holes are inclined outward and are equidistantly arranged on the flushing head In addition, the flushing range of the cleaning liquid on the stomach can be expanded, and the purpose of multi-directional flushing of the stomach can be achieved. The dissolved matter produced by the flushing will fall into the bottom layer of the stomach and contact the suction nozzle. The piston plate on the right side can suck the dissolved matter through the one-way valve three, the suction tube and the suction nozzle in the process of moving to the left, so that the dissolved matter enters the right turnover box. In the process of moving the piston plate on the right side to the right, the piston plate can squeeze the dissolved matter so that it passes through the one-way valve four and the collection tube into the collection box, thereby facilitating the collection and processing of the dissolved matter, and the gas generated inside the collection box is discharged from the exhaust valve. Therefore, the dissolved matter in the stomach can be extracted in time while flushing the stomach, so that a large amount of dissolved matter will not accumulate in the stomach, thereby improving the flushing and nursing effect and preventing discomfort to the patient caused by the accumulation of a large amount of dissolved matter. 2. The present invention drives the inverted cone-shaped flushing head into the stomach through the introduction tube, and then adjusts the position of the suction nozzle at the end of the suction tube. The suction tube is held and the inside of the introduction tube is inserted, so that the suction tube slides inside the tube sleeve through the anti-slip sleeve. During this process, the suction tube drives the suction nozzle at the bottom to extend under the stomach to facilitate the extraction of gastric liquid. When the suction tube is not under force, the anti-slip sleeve can limit it, preventing the suction tube from freely expanding and contracting and affecting the extraction work. Because the tube sleeve is fixed to the inner wall of the introduction tube by multiple rubber columns, the rubber columns play a supporting role between the introduction tube and the tube sleeve, preventing the esophagus from pressing the introduction tube to cause the cavity between the introduction tube and the tube sleeve to be closed, thereby ensuring the stability of the circulation of the cleaning liquid inside the cavity. Moreover, the rubber columns are flexible in design and have a buffering effect, preventing the esophagus from hard contact with the introduction tube to cause damage to the inner wall of the esophagus, thereby improving the safety of the device. 3. The present invention inserts the introduction tube into the stomach from the patient's mouth, and then contacts the limiting component with the patient's mouth skin. The two medical adhesive stickers on the inner side of the limiting component can adhere the arc-shaped pressing piece to the mouth. At the same time, the teeth of the upper and lower jaws in the mouth can overlap the outside of the protective sleeve. The protective sleeve can prevent the teeth from directly contacting the introduction tube, thereby affecting the normal conduction work, thereby improving the safety of the use of the introduction tube. Because the introduction tube passes through the airbag ring and contacts the inner side of the anti-slip strip, it can prevent the introduction tube from freely expanding and contracting in the body. When adjusting the length of the introduction tube extending out of the body, the introduction tube can be held and the opening of the fixed sleeve can be pushed or pulled to adjust the length of the introduction tube extending into the body. With the setting of the anti-slip strip, the gap between the fixed sleeve and the introduction tube can be sealed, and the inside of the mouth can be isolated from the outside world, preventing the liquid in the mouth from flowing out and the external impurities from entering the mouth to cause cross infection.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0017] See also Figures 1-10 , the present invention provides a technical solution: A gastroenterology nursing device for gastric lavage comprises a frame 1, a support plate 2 fixedly mounted within the frame 1, two cleaning fluid storage tanks 3 mounted on the support plate 2, and discharge valves 4 provided at the bottom of the cleaning fluid storage tanks 3. A collection assembly 5 is slidably mounted at the bottom of the inner wall of the frame 1. The collection assembly 5 comprises a collection box 501, which is slidably mounted at the bottom of the frame 1. An exhaust valve 502 and a discharge valve 503 are fixedly mounted on the upper and lower sides of the front of the collection box 501, respectively. Handles 504 are fixed on the left and right sides of the front of the collection box 501, respectively.

[0018] A driving assembly 6 is provided above the collecting assembly 5, and the driving assembly 6 is fixedly mounted on the support plate 2. The driving assembly 6 includes a motor 601, which is fixed on the support plate 2. The output shaft of the motor 601 is fixedly connected to a half gear 602. A sliding frame 603 is provided outside the half gear 602. A plurality of teeth 604 are provided on the upper and lower sides of the inner wall of the sliding frame 603, and the half gear 602 is meshed with the teeth 604; support rods 606 are fixedly connected to both sides of the sliding frame 603, and a piston plate 607 is fixed to one end of the support rod 606 away from the sliding frame 603. The turnover box 8 is fixed on the support plate 2, and the piston plate 607 is slidably mounted in the turnover box 8.

[0019] A slide groove 7 is provided on the support plate 2 , and two sliders 605 are fixed to the bottom of the sliding frame 603 . The sliders 605 are slidably connected in the slide groove 7 , and both the sliders 605 and the slide groove 7 are T-shaped.

[0020] One of the turnover boxes 8 is connected to a one-way valve 1 9 and a one-way valve 2 10 on the side away from the drive assembly 6, and the other turnover box 8 is connected to a one-way valve 3 12 and a one-way valve 4 13 on the side away from the drive assembly 6. A liquid extraction pipe 11 is connected to the one-way valve 1 9, and the other end of the liquid extraction pipe 11 is connected to one of the cleaning liquid storage tanks 3; a collecting pipe 14 is connected to the one-way valve 4 13, and one side of the collecting box 501 is connected to the end of the collecting pipe 14. A connecting pipe 15 and a suction pipe 16 are respectively connected to the one-way valve 2 10 and the one-way valve 3 12.

[0021] During operation, the half gear 602 drives the sliding frame 603 to the right via the upper teeth 604 in the sliding frame 603, and the sliding frame 603 drives the piston plate 607 to the right via the support rod 606. As the left piston plate 607 moves to the right, negative pressure is generated inside the left turnover box 8, enabling it to extract cleaning fluid from the cleaning fluid storage tank 3 through the one-way valve 9 and the liquid extraction pipe 11. When the cleaning fluid extraction is completed, the half gear 602 drives the sliding frame 603 to the left via the lower teeth 604 in the sliding frame 603, causing the sliding frame 603 to move to the left via the support rod 606, driving the piston plate 607 to move to the left, allowing the piston plate 607 to squeeze the cleaning fluid in the left turnover box 8, thereby facilitating continuous and synchronous left-right adjustment of the positions of the two piston plates 607.

[0022] The driving assembly 6 can squeeze the dissolve so that it passes through the one-way valve 13 and the collection pipe 14 and enters the collection box 501, thereby facilitating the collection and processing of the dissolve, and the gas generated inside the collection box 501 is discharged from the exhaust valve 502. Because a handle 504 is provided, the collection box 501 can be driven to slide at the bottom of the frame 1 through the handle 504, making it convenient to pull out the collection box 501 for cleaning or replacement.

[0023] Because of the presence of one-way valve 1 9 and one-way valve 2 10, one-way valve 1 9 can introduce the cleaning liquid into the left turnover box 8, and one-way valve 2 10 can prevent the external medium from flowing into the left turnover box 8. The liquid inside the turnover box 8 will not flow into the suction tube 11 through the one-way valve 1 9, and the cleaning liquid will flow into the connecting tube 15 through the one-way valve 2 10; the one-way valve 3 12 can prevent the solution inside the turnover box 8 from flowing back to the suction tube 16, thereby preventing the solution from flowing back to the stomach. The one-way valve 4 13 can block the external medium from entering the right turnover box 8, and the solution inside the right turnover box 8 enters the collection assembly 5 through the one-way valve 4 13 and the collection tube 14.

[0024] In this embodiment, the end of the connecting tube 15 away from the one-way valve 10 is connected to an introduction assembly 19. This introduction assembly 19 includes an introduction tube 191, the horizontal end of which is connected to the end of the connecting tube 15. The inner wall of the introduction tube 191 is provided with a plurality of rubber columns 192, with sleeves 193 fixed between the plurality of rubber columns 192. The sleeves 193 extend through the introduction tube 191. The suction tube 16 is sleeved within the sleeves 193, with an anti-slip sleeve 18 connected between the suction tube 16 and the sleeves 193. The anti-slip sleeve 18 is fixed to the horizontal end of the introduction tube 191. The connecting tube 15 communicates with the cavity between the introduction tube 191 and the sleeves 193. The bottom end of the introduction tube 191 is fixed to the flushing head 20. The suction tube 16 slides through the sleeves 193. The bottom end of the suction tube 16 is connected to the suction nozzle 17. The flushing head 20 is provided with a plurality of spray holes 21, and the suction nozzle 17 is located in the middle of the flushing head 20.

[0025] During operation, the suction tube 16 is held and the inside of the introduction tube 191 is inserted, so that the suction tube 16 slides inside the tube sleeve 193 through the anti-slip sleeve 18. When the suction tube 16 is not under force, the anti-slip sleeve 18 can limit its position, preventing the suction tube 16 from freely expanding and contracting and affecting the extraction work. Because the tube sleeve 193 is fixed to the inner wall of the introduction tube 191 by multiple rubber columns 192, the rubber columns 192 play a supporting role between the introduction tube 191 and the tube sleeve 193, preventing the esophagus from pressing on the introduction tube 191 and causing the cavity between the introduction tube 191 and the tube sleeve 193 to be closed, thereby ensuring the stability of the circulation of the cleaning liquid inside the cavity. Moreover, the rubber columns 192 are flexible in design and have a buffering effect, preventing the esophagus from hard contact with the introduction tube 191 and causing damage to the inner wall of the esophagus.

[0026] As a further solution of the present invention, the flushing head 20 is designed in an inverted cone shape, and a plurality of spray holes 21 are inclined outward and equidistantly arranged outside the flushing head 20, and the outer wall of the suction nozzle 17 is designed in an arc surface.

[0027] As the introduction tube 191 drives the head into the stomach, the inverted cone-shaped flushing head 20 is easily introduced into the stomach through the esophagus. Combined with the suction nozzle 17 with an arc-shaped outer wall, it is not easy to scratch the esophagus. The cleaning liquid in the connecting tube 15 enters the cavity between the introduction tube 191 and the tube sleeve 193. The cleaning liquid in the cavity enters the flushing head 20 and is sprayed toward the stomach from the external nozzle 21. Because several nozzles 21 are inclined outward and are equidistantly arranged outside the flushing head 20, the flushing range of the stomach by the cleaning liquid can be expanded.

[0028] As a further solution of the present invention, the outer cover of the introduction component 19 is connected to a limiting component 22, and the limiting component 22 includes a pressing piece 221. The pressing piece 221 is arc-shaped and has medical adhesive tapes 222 on both sides of the inner wall. A fixing sleeve 223 is fixed to the outer side of the pressing piece 221, and an airbag ring 224 is fixed inside the fixing sleeve 223. An anti-slip strip 225 is provided inside the airbag ring 224. The introduction tube 191 passes through the airbag ring 224 and contacts the inner side of the anti-slip strip 225. A protective sleeve 226 is fixed to the inner side of the pressing piece 221, and the introduction tube 191 is arranged inside the protective sleeve 226.

[0029] The medical adhesive tape 222 can adhere the arc-shaped pressing sheet 221 to the mouth, and at the same time, the teeth of the upper and lower jaws in the mouth can be overlapped on the outside of the protective sleeve 226. The protective sleeve 226 can prevent the teeth from directly contacting the introduction tube 191, thereby affecting the normal conduction work, and improving the safety of the use of the introduction tube 191.

[0030] Because the introduction tube 191 passes through the airbag ring 224 and contacts the inner side of the anti-slip strip 225, the introduction tube 191 can be prevented from freely expanding and contracting in the body; when adjusting the length of the introduction tube 191 extending into the body, the introduction tube 191 can be held and the introduction tube 191 can be pushed or pulled forcefully at the opening of the fixed sleeve 223 to adjust the length of the introduction tube 191 extending into the body. In conjunction with the setting of the anti-slip strip 225, the gap between the fixed sleeve 223 and the introduction tube 191 can be sealed, isolating the inside of the oral cavity from the outside world.

[0031] As a further embodiment of the present invention, a control panel 23 is fixedly mounted on the frame 1, and running wheels 24 are mounted at the four corners of the bottom of the frame 1. A push handle is fixed to the back of the frame 1. The control panel 23 can control the start and stop of the motor 601 and adjust the speed of the motor 601 to improve the degree of automation. The push handle can drive the running wheels 24 at the bottom of the frame 1 to roll on the ground, making it easier to move the device.

[0032] A method for using a gastric lavage nursing device in a gastroenterology department, the method comprising the following steps: During gastric lavage, the introduction tube 191 is inserted into the patient's stomach through the oral cavity. The stopper assembly 22 is then brought into contact with the patient's mouth skin. Two medical adhesive strips 222 on the inner side of the stopper assembly 22 adhere the curved pressing piece 221 to the mouth. Simultaneously, the teeth of the upper and lower jaws in the mouth overlap the outer side of the protective sleeve 226. The protective sleeve 226 prevents the teeth from directly contacting the introduction tube 191, which could affect normal operation and improve the safety of the introduction tube 191. Because the introduction tube 191 passes through the airbag ring 224 and contacts the inner side of the anti-slip strip 225, it prevents the introduction tube 191 from freely expanding and contracting within the body. To adjust the length of the introduction tube 191 extending into the body, the introduction tube 191 can be grasped and pushed or pulled at the opening of the fixed sleeve 223 to adjust its extension length. The anti-slip strip 225 seals the gap between the fixed sleeve 223 and the introduction tube 191, isolating the oral cavity from the outside world.

[0033] After the introduction tube 191 drives the inverted cone-shaped flushing head 20 into the stomach, the position of the suction nozzle 17 at the end of the suction tube 16 is adjusted. The suction tube 16 is held and the inside of the introduction tube 191 is inserted so that the suction tube 16 slides inside the tube sleeve 193 through the anti-slip sleeve 18. During this process, the suction tube 16 drives the suction nozzle 17 at the bottom to extend into the bottom of the stomach to facilitate the extraction of stomach liquid. When the suction tube 16 is not under force, the anti-slip sleeve 18 can limit it to prevent the suction tube 16 from freely expanding and contracting and affecting the extraction work.

[0034] Because the sleeve 193 is fixed to the inner wall of the introduction tube 191 by multiple rubber columns 192, the rubber columns 192 play a supporting role between the introduction tube 191 and the sleeve 193, preventing the esophagus from compressing the introduction tube 191 and causing the cavity between the introduction tube 191 and the sleeve 193 to be closed, thereby ensuring the stability of the circulation of the cleaning liquid inside the cavity. The rubber columns 192 are flexible in design and have a buffering effect, preventing the esophagus from causing damage to the inner wall of the esophagus due to hard contact between the esophagus and the introduction tube 191.

[0035] When the stomach is being cleaned, the control motor 601 is operated to drive the half gear 602 to rotate clockwise, so that the half gear 602 drives the sliding frame 603 to move to the right through the upper teeth 604 in the sliding frame 603, and the sliding frame 603 drives the piston plate 607 to move to the right through the support rod 606. During the movement of the left piston plate 607 to the right, negative pressure is generated inside the turnover box 8 on the left, so that it can extract cleaning liquid from the cleaning liquid storage tank 3 through the one-way valve 19 and the liquid extraction pipe 11. The one-way valve 19 can introduce the cleaning liquid into the left turnover box 8, and the one-way valve 2 10 can prevent the external medium from flowing into the left turnover box 8; when After the cleaning fluid is extracted, the half gear 602 drives the sliding frame 603 to the left via the teeth 604 at the bottom of the sliding frame 603, causing the sliding frame 603 to drive the piston plate 607 to move to the left via the support rod 606, allowing the piston plate 607 to squeeze the cleaning fluid in the left turnover box 8. The liquid in the turnover box 8 will not flow into the extraction pipe 11 through the one-way valve 1 9. Instead, the cleaning fluid will flow into the connecting pipe 15 through the one-way valve 2 10. The cleaning fluid in the connecting pipe 15 enters the cavity between the introduction pipe 191 and the pipe sleeve 193. The cleaning fluid in the cavity enters the flushing head 20 and is sprayed toward the stomach from the external nozzles 21. Because the nozzles 21 are tilted outward and evenly spaced outside the flushing head 20, the range of the cleaning fluid flushing the stomach can be expanded, achieving the purpose of multi-directional flushing of the stomach.

[0036] The stomach is flushed with flushing fluid, and the resulting solute will fall into the bottom layer of the stomach and contact the suction nozzle 17. The right piston plate 607 can suck the solute through the one-way valve three 12, the suction tube 16 and the suction nozzle 17 during the movement to the left, so that the solute enters the right turnover box 8. The one-way valve three 12 can prevent the solute inside the turnover box 8 from flowing back to the suction tube 16, thereby preventing the solute from flowing back to the stomach; the one-way valve four 13 can block the external medium from entering the right turnover box 8. During the movement of the right piston plate 607 to the right, the piston plate 607 can squeeze the solute so that it passes through the one-way valve four 13 and the collection tube 14 into the collection box 501, thereby facilitating the collection and processing of the solute, and the gas generated inside the collection box 501 is discharged from the exhaust valve 502. Therefore, while flushing the stomach, the solute in the stomach can be extracted in time, so that a large amount of solute will not accumulate in the stomach.

A method for using a gastroenterology gastric lavage nursing device, according to any one of claims 1 to 7, characterized in that: The method of use comprises the following steps: During gastric lavage care, the introduction tube (191) is inserted into the stomach from the patient's oral cavity, and then the limiting component (22) is brought into contact with the patient's mouth skin. The two medical adhesive tapes (222) on the inner side of the limiting component (22) can adhere the arc-shaped pressing piece (221) to the mouth, and at the same time, the teeth of the upper and lower jaws in the oral cavity can be overlapped outside the protective sleeve (226). The protective sleeve (226) can prevent the teeth from directly contacting the introduction tube (191) and thus affecting the normal conduction work, thereby improving the use safety of the introduction tube (191). ) penetrates the airbag ring (224) and contacts the inner side of the anti-slip strip (225), which can prevent the introduction tube (191) from freely expanding and contracting in the body. When adjusting the length of the introduction tube (191) extending into the body, the introduction tube (191) can be held and the introduction tube (191) can be pushed or pulled at the opening of the fixed sleeve (223) to adjust the length of the introduction tube extending into the body. In conjunction with the setting of the anti-slip strip (225), the gap between the fixed sleeve (223) and the introduction tube (191) can be sealed to isolate the inside of the oral cavity from the outside world. After the introduction tube (191) drives the inverted cone-shaped flushing head (20) into the stomach, the position of the suction nozzle (17) at the end of the suction tube (16) is adjusted, and the suction tube (16) is held and the inside of the introduction tube (191) is inserted, so that the suction tube (16) slides inside the tube sleeve (193) through the anti-slip sleeve (18). During this process, the suction tube (16) drives the suction nozzle (17) at the bottom to extend into the lower part of the stomach to facilitate the extraction of stomach liquid. When the suction tube (16) is not subjected to force, the anti-slip sleeve (18) can play a role in limiting its position, preventing the suction tube (16) from sliding. 16) Free expansion and contraction affects the extraction work. Since the tube sleeve (193) is fixed to the inner wall of the introduction tube (191) through multiple rubber columns (192), the rubber columns (192) play a supporting role between the introduction tube (191) and the tube sleeve (193), preventing the esophagus from pressing the introduction tube (191) to cause the cavity between the introduction tube (191) and the tube sleeve (193) to be closed, thereby ensuring the stability of the circulation of the cleaning liquid inside the cavity. Moreover, the rubber column (192) is a flexible design and has a buffering effect, preventing the esophagus from being in hard contact with the introduction tube (191) to cause damage to the inner wall of the esophagus; When the stomach is cleaned, the motor (601) is controlled to work so that it drives the half gear (602) to rotate clockwise, so that the half gear (602) drives the sliding frame (603) to move to the right through the upper teeth (604) in the sliding frame (603), and the sliding frame (603) drives the piston plate (607) to move to the right through the support rod (606).
