Description

Technical Field

[0001] The present invention relates to the field of medical devices, in particular to a gastrointestinal decompression device for general surgery. Background Art

[0002] The primary purpose of gastrointestinal decompression is to completely remove gastric contents through the placement of a gastric tube, thereby emptying the stomach and reducing abdominal distension. This reduces the flow of gastric and intestinal fluid into the distal duodenum and jejunum, lessening irritation to digestive organs such as the gallbladder, pancreas, and intestines, and thus helping to alleviate symptoms.

[0003] Patients with clinical pancreatitis can undergo an indwelling gastric tube, which reduces the stimulation of pancreatic juice by gastric juice and better controls pancreatitis. During the treatment of intestinal obstruction, due to intestinal obstruction, a large amount of gastric juice still flows into the intestine, causing a gradual increase in intestinal pressure. Gastrointestinal decompression can help alleviate intestinal obstruction. After indwelling gastrointestinal decompression, the drainage can also be used to observe changes in the disease. Bloody drainage indicates the presence of blood in the gastric juice, while fecal drainage indicates a lower site of obstruction. Therefore, in addition to its therapeutic role, gastrointestinal decompression also has a certain diagnostic value.

[0004] Existing gastrointestinal decompression devices will extract the patient's stomach contents during the process of decompressing the patient's stomach. However, the patient's stomach is always secreting gastric acid. At this time, the substance in the patient's stomach that offsets the gastric acid is reduced. Over a long period of time, the gastric acid will corrode the gastric mucosa, causing stomach discomfort in the patient. Summary of the Invention

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] See also Figures 1 to 7 In an embodiment of the present invention, a gastrointestinal decompression device for general surgery includes:

[0031] Base 1, a mixing chamber 2 and a separation chamber 27 are provided on the base 1, the mixing chamber 2 is connected and conducted with the separation chamber 27, a mixing pump liquid component is provided on the mixing chamber 2, and the mixing pump liquid component includes a No. 1 drive device 3 fixedly mounted on the mixing chamber 2, the output shaft of the No. 1 drive device 3 is connected to the stirring rod 11 arranged in the mixing chamber 2 through a linear transmission structure, and the linear transmission structure includes two transmission wheels 4 symmetrically mounted in the mixing chamber 2, a transmission chain 5 is provided on the two transmission wheels 4, and one of the transmission wheels 4 is provided with a transmission chain 5, and one of the transmission wheels 4 is provided with a transmission chain 5. The transmission wheel 4 is connected to the output shaft of the first drive device 3, and the transmission chain 5 is connected to the mounting plate 8 set in the mixing chamber 2 through a chimeric kit. The chimeric kit includes a chimeric member 7 fixedly mounted on the mounting plate 8, and the chimeric member 7 is provided with a groove. The groove slides with the protrusion 6 fixedly mounted on the transmission chain 5. The mounting plate 8 is rotatably connected to the stirring rod 11, and two sliding sleeves 9 are symmetrically provided at both ends of the mounting plate 8. The sliding sleeve 9 is slidably connected to the guide rod 10 fixedly mounted in the mixing chamber 2;

[0032] One of the transmission wheels 4 is connected to a No. 1 bevel gear set 14 arranged in the mixing chamber 2. The No. 1 bevel gear set 14 includes a No. 1 bevel gear and a No. 2 bevel gear rotatably mounted on the mixing chamber 2. The No. 1 bevel gear is connected to the transmission wheel 4. The No. 2 bevel gear is connected to a liquid pump 16 arranged on the mixing chamber 2 through a No. 1 belt 15. The liquid inlet of the liquid pump 16 passes through the mixing chamber 2 and extends into the interior thereof.

[0033] When in use, by controlling the operation of the No. 1 driving device 3, the transmission wheel 4 connected thereto is driven to rotate, and a transmission chain 5 is sleeved on the transmission wheel 4. Therefore, when the transmission wheel 4 rotates, the transmission chain 5 will follow the movement and drive the protrusion 6 connected thereto to move. The protrusion 6 slides with the groove on the fitting 7 to drive the fitting 7 to move, and drives the mounting plate 8 connected to the fitting 7 to move. The mounting plate 8 drives the stirring rod 11 to stir the nutrients and gastric contents in the mixing chamber 2, so that the two are fully mixed, which is convenient for the patient's stomach to absorb the mixture. The mounting plate 8 is slidably connected to the guide rod 10 by the sliding sleeve 9, which makes it more stable during the movement of the mounting plate 8, thereby making the stirring rod 11 more stable when it moves, so that it will not interfere with the mixing chamber 2 The inner wall of the mixing chamber 2 interferes with the stirring rod 11 and destroys the structure of the mixing chamber 2. Through the above arrangement, the patient's gastric contents and the nutrient solution are stirred and mixed. Since the patient's previous gastric contents exist in the mixture, the patient will not have a rejection reaction when absorbing it, thereby improving the patient's absorption capacity of the nutrient solution and speeding up the patient's recovery to a certain extent. At the same time, the transmission wheel 4 drives the liquid pump 16 to work through the No. 1 bevel gear set 14 and the No. 1 belt 15, thereby realizing the same speed operation of the liquid pump 16 and the stirring rod 11, that is, as the speed of the stirring rod 11 moves faster or slower, the pumping speed of the liquid pump 16 also speeds up or slows down, so that the speed of pumping the mixture is the same as the speed of stirring the mixture, thereby avoiding insufficient mixing of the nutrient solution after the pumping speed is increased.

[0034] The transmission chain 5 is a quasi-circular structure. During its continuous movement, it will drive the protrusion 6 to perform a quasi-circular motion, and drive the mounting plate 8 and the stirring rod 11 to reciprocate in the mixing chamber 2 through the fitting 7. While the structure is simple, it achieves sufficient mixing of the stomach contents and nutrients.

[0035] It should be noted that the length of the above-mentioned engaging member 7 needs to be greater than the distance between the layers of the transmission chain 5 .

[0036] Please refer again Figure 5 The stirring rod 11 is connected to the mixing chamber 2 through a toothing structure, and the toothing structure includes a rack plate 13 fixedly installed in the mixing chamber 2, and the rack plate 13 is engaged with a gear 12 provided on the stirring rod 11 and coaxial therewith.

[0037] During the reciprocating motion of the mounting plate 8 in the mixing chamber 2, the stirring rod 11 is driven to reciprocate, and the gear 12 provided on the stirring rod 11 is moved, and the gear 12 is always in a meshing state with the rack plate 13. Therefore, during the reciprocating motion of the stirring rod 11, the stirring rod 11 can rotate along with the gear 12, thereby more fully mixing the gastric contents and nutrients in the mixing chamber 2, thereby improving the patient's ability to absorb the nutrients.

[0038] Please refer again Figure 3 、 Figure 4 The liquid inlet of the liquid pump 16 is connected to the feeding assembly installed on the mixing chamber 2, and the feeding assembly includes a horizontal plate 17 fixedly connected to the liquid inlet of the liquid pump 16, and two floats 18 are symmetrically provided on the horizontal plate 17. The floats 18 are connected to a sealing plate 20 through a connecting frame 19 that passes through the mixing chamber 2. The sealing plate 20 is sealed and slidably connected with a conducting pipe 21 that is provided on the mixing chamber 2 and communicates with the mixing chamber 2, and a through hole is provided on the sealing plate 20, a one-way valve 22 is provided on the conducting pipe 21, and an extrusion structure is provided on the end of the conducting pipe 21 away from the mixing chamber 2;

[0039] The extrusion structure includes a storage cylinder body 23 connected to the conducting tube 21, a sealing piston 24 is sealingly and slidingly provided in the storage cylinder body 23, a vertical rod 25 passing through the storage cylinder body 23 is installed on the sealing piston 24, and a spring 26 is sleeved on the vertical rod 25, one end of the spring 26 is connected to the sealing piston 24, and the other end is connected to the inner wall of the storage cylinder body 23.

[0040] When in use, a liquid supply chamber 36 is provided on one side of the mixing chamber 2, and the liquid supply chamber 36 is connected to the mixing chamber 2 through a plurality of small holes, so as to filter the gastric contents and the large particles of solids in the nutrient solution, thereby reducing the patient's digestive burden. At the same time, the liquid inlet of the liquid pump 16 is provided in the liquid supply chamber 36, and the liquid inlet of the liquid pump 16 is connected with a bellows, and under the action of the cross plate 17 and the float 18, the end of the bellows away from the liquid pump 16 can always be immersed in the mixture, ensuring that the liquid pump 16 can continuously pump the mixture in the mixing chamber 2. At the same time, since the bellows is provided in the liquid supply chamber 36, interference between the stirring rod 11 and the bellows is avoided when the stirring rod 11 rotates, and since the gastric contents of the patient need to be filtered, when the solids After being filtered, it flows back into the mixing chamber 2, so that the gastric contents will gradually decrease with the progress of pumping and extraction. At this time, the volume of the mixture in the mixing chamber 2 will decrease. When the liquid level of the mixture drops, the height of the cross plate 17 and the float 18 will drop accordingly, and the sealing plate 20 will be driven downward by the connecting frame 19 until the through hole on the sealing plate 20 coincides with the conducting tube 21, so that the conducting tube 21 is connected. At this time, under the action of the spring 26, the sealing piston 24 will move downward and squeeze the nutrient stored in the storage cylinder 23 and transport it to the mixing chamber 2, so that the total amount of substance in the mixing chamber 2 remains constant for easy absorption by the patient, while ensuring the balance between the pumped in volume and the sucked out volume, preventing overfilling and deficiency of body fluids, and imbalance of body fluids.

[0041] Please refer again Figure 2 、 Figure 6A negative pressure component is provided in the separation chamber 27, and the negative pressure component includes a No. 2 drive device 29 fixedly mounted on the separation chamber 27. The output shaft of the No. 2 drive device 29 is connected to a negative pressure pump 30 fixedly mounted in the separation chamber 27. The negative pressure pump 30 is connected to a No. 2 bevel gear set 31 provided in the separation chamber 27. The No. 2 bevel gear set 31 includes a No. 3 bevel gear and a No. 4 bevel gear rotatably mounted on the separation chamber 27 and meshing with each other. The No. 3 bevel gear is connected to the impeller shaft of the negative pressure pump 30.

[0042] When in use, the No. 1 drive device 3 and the No. 2 drive device 29 work simultaneously, driving the liquid pump 16 and the negative pressure pump 30 to work synchronously. The No. 1 drive device 3 and the No. 2 drive device 29 are electrically connected, and when the two are working, their output speeds are the same, so that the pumping volume and the suction volume are balanced, preventing overfilling and deficiency of body fluids and imbalance of body fluids.

[0043] Please refer again Figure 6 、 Figure 7 The fourth bevel gear is connected to the filter assembly through the second belt 32. The filter assembly includes a baffle installed in the separation chamber 27. A circumferential piece 33 is rotatably installed on the baffle. The circumferential piece 33 is connected to the second belt 32, and the circumferential piece 33 is connected to the brush plate 34 arranged in the separation chamber 27 through a connecting structure. The connecting structure includes a pulley 35 rotatably installed on the end of the circumferential piece 33 away from its rotation center. The pulley 35 slides with the long groove arranged along the length direction of the brush plate 34. Two slide grooves are also symmetrically provided in the separation chamber 27. The two ends of the brush plate 34 are slidably arranged in the slide grooves, and the brush plate 34 is in contact with the filter plate 28 arranged in the separation chamber 27.

[0044] The separation chamber 27 is divided into two chambers under the action of the filter plate 28, wherein the upper chamber is used to hold the gastric contents, and the lower chamber is provided with an ultraviolet searchlight to sterilize the gastric contents after filtration, so as to prevent the gastric contents from flowing back to the patient's tail and causing the patient's tail infection due to the presence of bacteria. At the same time, when the negative pressure pump 30 pumps the patient's gastric contents into the upper chamber, the filter plate 28 filters the solids in the gastric contents. This is mainly because the digestive ability of patients after gastrointestinal surgery is poor. If the solids are digested, it will increase the burden on the stomach. However, due to the limited filtering capacity of the filter plate 28 and the fact that the gastric contents are not as good as those of the patients after gastrointestinal surgery, the gastric contents are not as good as those of the patients after gastrointestinal surgery. As more and more solids are filtered, the solids will block the filter holes on the filter plate 28. When the negative pressure pump 30 is working, the circumferential member 33 will be driven to rotate through the No. 2 bevel gear set 31 and the No. 2 belt 32. During the rotation of the circumferential member 33, the interaction between the pulley 35 and the long groove drives the brush plate 34 to reciprocate, cleaning the fixed parts on the filter plate 28, so that the fixed parts tend to move toward the edge of the filter plate 28, thereby improving the filtering effect of the filter plate 28. At the same time, the brush plate 34 is slidably set in the slide groove, making it more stable during its reciprocating motion, improving the structural stability of the device, and ensuring that the device can operate effectively and stably for a long time.

[0045] In summary, when in use, by controlling the operation of the No. 1 driving device 3, the transmission wheel 4 connected thereto is driven to rotate, and a transmission chain 5 is sleeved on the transmission wheel 4. Therefore, when the transmission wheel 4 rotates, the transmission chain 5 will follow the movement and drive the protrusion 6 connected thereto to move. The protrusion 6 slides with the groove on the fitting 7 to drive the fitting 7 to move, and drives the mounting plate 8 connected to the fitting 7 to move. The mounting plate 8 drives the stirring rod 11 to stir the nutrients and gastric contents in the mixing chamber 2, so that the two are fully mixed, which is convenient for the patient's stomach to absorb the mixture, and the mounting plate 8 is slidably connected to the guide rod 10 through the sliding sleeve 9, so that the mounting plate 8 is more stable during the movement, thereby making the stirring rod 11 more stable when it moves, so that it will not interfere with the mixing chamber 2. The inner wall of the chamber 2 interferes, thereby destroying the structure of the stirring rod 11 and the mixing chamber 2. Through the above arrangement, the patient's gastric contents and the nutrient solution are stirred and mixed. Since the patient's previous gastric contents exist in the mixture, the patient will not have a rejection reaction when absorbing it, thereby improving the patient's absorption capacity of the nutrient solution and accelerating the patient's recovery speed to a certain extent. At the same time, the transmission wheel 4 drives the liquid pump 16 to work through the first bevel gear set 14 and the first belt 15, thereby achieving the same speed operation of the liquid pump 16 and the stirring rod 11, that is, as the speed of the stirring rod 11 moves faster or slower, the pumping speed of the liquid pump 16 also speeds up or slows down, so that the speed of pumping the mixture is the same as the speed of stirring the mixture, thereby avoiding insufficient mixing of the nutrient solution after the pumping speed is increased;

[0046] The transmission chain 5 is a quasi-circular structure. During its continuous movement, it drives the protrusion 6 to perform a quasi-circular motion, and drives the mounting plate 8 and the stirring rod 11 to reciprocate in the mixing chamber 2 through the fitting 7. While the structure is simple, it achieves sufficient mixing of the stomach contents and nutrients.

[0047] During the reciprocating motion of the mounting plate 8 in the mixing chamber 2, the stirring rod 11 is driven to reciprocate, and the gear 12 provided on the stirring rod 11 is moved. The gear 12 is always in meshing state with the rack plate 13. Therefore, during the reciprocating motion of the stirring rod 11, the stirring rod 11 can rotate along with the gear 12, thereby more fully mixing the gastric contents and the nutrient in the mixing chamber 2, thereby improving the patient's ability to absorb the nutrient;

[0048] When in use, a liquid supply chamber 36 is provided on one side of the mixing chamber 2, and the liquid supply chamber 36 is connected to the mixing chamber 2 through a plurality of small holes, so as to filter the gastric contents and the large particles of solids in the nutrient solution, thereby reducing the patient's digestive burden. At the same time, the liquid inlet of the liquid pump 16 is provided in the liquid supply chamber 36, and the liquid inlet of the liquid pump 16 is connected with a bellows, and under the action of the cross plate 17 and the float 18, the end of the bellows away from the liquid pump 16 can always be immersed in the mixture, ensuring that the liquid pump 16 can continuously pump the mixture in the mixing chamber 2. At the same time, since the bellows is provided in the liquid supply chamber 36, interference between the stirring rod 11 and the bellows is avoided when the stirring rod 11 rotates, and since the gastric contents of the patient need to be filtered, when the solids After being filtered, it flows back into the mixing chamber 2, so that the gastric contents will gradually decrease as the pumping and extraction proceed. At this time, the volume of the mixture in the mixing chamber 2 will decrease. When the liquid level of the mixture drops, the height of the cross plate 17 and the float 18 will drop accordingly, and the sealing plate 20 will be driven downward by the connecting frame 19 until the through hole on the sealing plate 20 coincides with the conducting tube 21, so that the conducting tube 21 is connected. At this time, under the action of the spring 26, the sealing piston 24 will move downward and squeeze the nutrient solution stored in the storage cylinder 23 and deliver it to the mixing chamber 2, so that the total amount of substances in the mixing chamber 2 remains constant for easy absorption by the patient, while ensuring the balance between the pumped in volume and the sucked out volume, preventing overfilling and deficiency of body fluids and imbalance of body fluids;

[0049] During use, the first drive device 3 and the second drive device 29 operate simultaneously, driving the liquid pump 16 and the negative pressure pump 30 to operate synchronously. The first drive device 3 and the second drive device 29 are electrically connected, and when they are in operation, their output speeds are the same, so that the pumping volume and the suction volume are balanced, preventing overfilling and deficiency of body fluids and imbalance of body fluids.

[0050] The separation chamber 27 is divided into two chambers under the action of the filter plate 28, wherein the upper chamber is used to hold the gastric contents, and the lower chamber is provided with an ultraviolet searchlight to sterilize the gastric contents after filtration, so as to prevent the gastric contents from flowing back to the patient's tail and causing the patient's tail infection due to the presence of bacteria. At the same time, when the negative pressure pump 30 pumps the patient's gastric contents into the upper chamber, the filter plate 28 filters the solids in the gastric contents. This is mainly because the digestive ability of patients after gastrointestinal surgery is poor. If the solids are digested, it will increase the burden on the stomach. However, due to the limited filtering capacity of the filter plate 28 and the fact that the gastric contents are not as good as those of the patients after gastrointestinal surgery, the gastric contents are not as good as those of the patients after gastrointestinal surgery. As more and more solids are filtered, the solids will block the filter holes on the filter plate 28. When the negative pressure pump 30 is working, the circumferential member 33 will be driven to rotate through the No. 2 bevel gear set 31 and the No. 2 belt 32. During the rotation of the circumferential member 33, the interaction between the pulley 35 and the long groove drives the brush plate 34 to reciprocate, cleaning the fixed parts on the filter plate 28, so that the fixed parts tend to move toward the edge of the filter plate 28, thereby improving the filtering effect of the filter plate 28. At the same time, the brush plate 34 is slidably set in the slide groove, making it more stable during its reciprocating motion, improving the structural stability of the device, and ensuring that the device can operate effectively and stably for a long time.
