Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a clinical ascites drainage device in gastroenterology. Background Art

[0002] Ascites, also known as abdominal effusion, usually accumulates in the abdominal cavity. Under normal circumstances, there will be a small amount of fluid in the abdominal cavity to lubricate the organs, but when the amount of fluid exceeds the normal range, abdominal effusion will form. This is generally related to diseases, including liver disease, heart disease and renal insufficiency. Drainage equipment is needed to drain ascites. In the prior art, the structure of clinical ascites drainage equipment in gastroenterology is relatively simple, that is, a puncture needle and a drainage tube. The puncture needle is inserted into the patient's body and the excess ascites is drained out by the water pressure inside the abdominal cavity. Due to the different ascites content of each patient and individual differences, The water pressure generated is different, which may cause the problem of excessive or insufficient drainage of ascites. Under the influence of differentiated water pressure, it is easy to cause incomplete drainage or excessive drainage, resulting in residual ascites or too little ascites in the patient. Clinically, users sometimes use pumps to generate negative pressure and perform suction, but the pump is not safe enough for the patient's body and cannot flexibly adjust the suction force according to the patient's condition in time, which may cause the number of drainage punctures to double, causing pain to the patient. Therefore, the present invention is committed to designing a clinical ascites drainage device in the Department of Gastroenterology that can adjust the drainage volume according to the patient's actual situation.

[0005] As a preferred solution of the present invention, the cleaning mechanism is fixedly installed on the top of the base plate and is located on the left side of the liquid storage tank. The cleaning mechanism includes a water pump and a disinfectant storage tank installed on the top of the base plate. The water inlet end of the water pump is connected to the disinfectant storage tank, and the water outlet end of the water pump is fixedly connected to a water inlet pipe. The inner wall of the water inlet pipe is movably sleeved with a limiting ring, and a sealing ring is glued to the top of the limiting ring. The interior of the water pump is also movably sleeved with a spring 1 located at the bottom of the limiting ring, and the two ends of the spring 1 are elastically connected to the limiting ring and the water inlet pipe respectively. The top of the sealing ring abuts against the top of the inner wall of the water inlet pipe, and the outer surface of the sealing ring is interference fit with the inner wall of the water inlet pipe. The top opening of the water inlet pipe and the left end of the diverter are adapted to each other.

[0006] As a preferred solution of the present invention, a handle is fixedly connected to the right end of the diverter, and a plurality of groups of circular protrusions of different sizes are provided on the right side of the inner wall of the handle, and the circular protrusions are made of rubber blocks.

[0007] As a preferred solution of the present invention, the shape of the piston is dumbbell-shaped, and both ends of the piston are interference fit with the inner wall of the diverter.

[0008] As a preferred solution of the present invention, the shape of the mounting ring is annular, and the mounting ring can slide along the surface of the diverter.

[0009] As a preferred solution of the present invention, the inner diameter values ​​of drain tube one, drain tube two and drain tube three increase successively from left to right, the width value of the liquid opening is equal to the inner diameter value of drain tube three, and drain tube one, drain tube two and drain tube three are all connected to the inner cavity of the drain.

[0010] As a preferred solution of the present invention, both the one-way plate one and the one-way plate two are serrated, and the serration directions of the one-way plate one and the one-way plate two are opposite, and the front and rear sides of the bottom of the outer surface of the diverter are fixedly connected with limiting blocks, and the top surfaces of the two groups of the limiting blocks form an angle of 210°, and the bottom of the connecting plate abuts against the top of the limiting block.

[0011] As a preferred solution of the present invention, the piston can move rightward in the inner cavity of the diverter to the rightmost side of the diverter and abut against the right side of the inner wall of the diverter, and at this time, the spring 2 is compressed to the maximum extent.

[0012] The beneficial effects of the present invention are as follows:

[0013] The present invention has been optimized and redesigned to provide a drainage device with a drainer, a piston, a sealing cylinder and a second spring as the core. The piston is elastically connected to the second spring to the right, so that the second spring is responsible for resetting the piston, and at the same time, the pressure from the patient's abdominal cavity is automatically sensed through different displacements generated by the compression of the piston, and converted into different positions of the piston in the inner cavity of the drainer, that is, the greater the pressure in the abdominal cavity, the closer the piston is to the right. The inner wall of the drainer is sealed by arranging a sealing cylinder located on the left side of the piston, and a liquid through hole is opened at the right position of the bottom of the sealing cylinder, so that the piston moves to the right. When the piston is moved, the liquid outlet can only overlap with the drainage pipe 1, the drainage pipe 2 or the drainage pipe 3, so as to discharge the ascites. The piston and the connecting plate and the clamping strip are connected by a connecting block and a mounting ring. When the piston is moved to the right by the ascites under the action of water pressure, the clamping strip passes smoothly through the inclined surface design of the serrations on the surface of the one-way plate 1, and the irreversible design produced by the mutual clamping of the clamping strip and the serrations of the one-way plate 1 is utilized to make the piston stop and maintain the predetermined position each time after moving to the farthest position to the right. In this way, the greater the peritoneal water pressure, the larger the required drainage channel area, thereby achieving the function of automatically adapting to different ascites water pressures.

[0014] The device is also designed with a one-way plate 2 located on the rear side of the outer surface of the drainer, and the direction of its serrated slope is opposite to that of the one-way plate 1, so that the connecting plate and the clamping strip can move to the left along the surface of the one-way plate 2, but cannot move to the right. By removing the puncture needle, the left head of the drainer is abutted against the sealing ring, and the limiting ring is driven to move downward to the deep inner cavity of the water inlet pipe, and the spring 1 is compressed, so that the sealing ring is squeezed and deformed, and a seal is provided between the drainer and the limiting ring. The disinfectant in the disinfectant storage tank is pumped into the inner cavity of the drainer by a water pump. When the piston is subjected to high pressure from the disinfectant, the clamping strip is abutted against the serrated teeth of the one-way plate 2 to maintain a predetermined position, which helps the liquid port to overlap with the drainage pipe 1, the drainage pipe 2 or the drainage pipe 3, so that the high-pressure disinfectant passes through the liquid port through one of the drainage pipes 1, the drainage pipe 2 and the drainage pipe 3 each time for centralized flushing, which helps to efficiently clean the equipment.

[0015] The inner diameters of drain tube one, drain tube two and drain tube three are designed to increase in sequence, which means that as the piston moves further to the right, the pressure of the ascites increases, and thus a larger passing area is required to ensure the smoothness of the drainage work. The device distributes drain tube one, drain tube two and drain tube three according to the displacement generated by the piston compressing spring two. When the piston drives the sealing cylinder to make the liquid port coincide with drain tube three, it means that spring two is compressed to the greatest extent, that is, the rebound force generated is the greatest, and the ascites pressure on the piston is also the greatest. At this time, drain tube three with the largest area is just used to provide a channel for the drainage of a large amount of ascites. When the ascites water pressure is small, the compressed stroke of spring two is used to confirm, and the piston and the sealing cylinder are driven to automatically move to a position that coincides with drain tube two or drain tube one, thereby achieving automatic switching of the drainage channel area.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 10As shown, an embodiment of the present invention provides a clinical ascites drainage device for gastroenterology, including a bottom plate 1, a liquid storage tank 2 and a cleaning mechanism 3, three groups of hoses 4 are fixedly connected to the top of the liquid storage tank 2, and also include a drain 5 located above the liquid storage tank 2, a puncture needle 12 is installed at the left end of the drain 5, and a drainage tube 9, a drainage tube 2 10 and a drainage tube 3 11 are equidistantly installed on the bottom of the outer surface of the drain 5 from left to right, the three groups of hoses 4 are respectively connected to the drainage tube 1 9, the drainage tube 2 10 and the drainage tube 3 11, a piston 15 is provided at the middle sealing sleeve of the drain 5, one end of the piston 15 is fixedly connected to a sealing cylinder 23, a liquid through port 24 is provided on the right side of the bottom of the sealing cylinder 23, and a placement groove 16 is provided at the other end of the piston 15 for placing A spring 2 17 is movably sleeved inside the placement groove 16, and the two ends of the spring 2 17 are elastically connected to the placement groove 16 and the drain 5 respectively. One end of the piston 15 is located on the left side of the discharge pipe 1 9. A slide groove 6 is provided on the right side of the top of the drain 5. A connecting block 18 is movably clamped on the left side of the inner wall of the slide groove 6. The bottom of the connecting block 18 is fixedly connected to the piston 15. A mounting ring 19 is fixedly connected to the top of the connecting block 18. A slip ring 20 is movably sleeved on the outer surface of the mounting ring 19. A one-way plate 13 and a one-way plate 2 14 are fixed on the front and rear sides of the outer surface of the drain 5 respectively. A connecting plate 21 is fixedly connected to the left side of the slip ring 20. A clamping strip 22 is fixedly connected to the inner side of the connecting plate 21. The one-way plate 13 is limitedly clamped on the surface of the clamping strip 22.

[0029] The present invention has been optimized and redesigned to provide a drainage device with a drain 5, a piston 15, a sealing cylinder 23 and a spring 17 as the core. The piston 15 is elastically connected to the spring 17 to the right, so that the spring 17 is responsible for resetting the piston 15. At the same time, the pressure from the patient's abdominal cavity is automatically sensed by the different displacements generated by the compression of the piston 15, and converted into different positions of the piston 15 in the inner cavity of the drain 5. That is, the greater the pressure in the abdominal cavity, the closer the piston 15 is to the right. The inner wall of the drain 5 is sealed by arranging a sealing cylinder 23 located on the left side of the piston 15, and a liquid through hole 24 is opened at the right position of the bottom of the sealing cylinder 23, so that the piston 15 can move to the right. When moving to the right, the liquid outlet 24 can only coincide with the drainage tube 1 9 or the drainage tube 2 10 or the drainage tube 3 11, so as to discharge the ascites. The piston 15 is connected to the connecting plate 21 and the clamping strip 22 by means of the connecting block 18 and the mounting ring 19. When the piston 15 is moved to the right by the ascites under the action of the water pressure, the clamping strip 22 can pass smoothly through the inclined surface design of the serrations on the surface of the one-way plate 13. The irreversible design produced by the mutual clamping of the clamping strip 22 and the serrations of the one-way plate 13 is utilized to make the piston 15 stop and maintain the predetermined position each time after moving to the farthest position to the right. In this way, the greater the peritoneal water pressure, the larger the drainage channel area required, thereby achieving the function of automatically adapting to different ascites water pressures.

[0030] Among them, the cleaning mechanism 3 is fixedly installed on the top of the base plate 1 and is located on the left side of the liquid storage bin 2. The cleaning mechanism 3 includes a water pump 31 and a disinfectant storage tank 32 installed on the top of the base plate 1. The water inlet end of the water pump 31 is connected to the disinfectant storage tank 32, and the water outlet end of the water pump 31 is fixedly connected to a water inlet pipe 33. The inner wall of the water inlet pipe 33 is movably sleeved with a limiting ring 34, and a sealing ring 35 is glued to the top of the limiting ring 34. The inside of the water pump 31 is also movably sleeved with a spring 36 located at the bottom of the limiting ring 34. The two ends of the spring 36 are elastically connected to the limiting ring 34 and the water inlet pipe 33 respectively. The top of the sealing ring 35 abuts against the top of the inner wall of the water inlet pipe 33, and the outer surface of the sealing ring 35 is interference fit with the inner wall of the water inlet pipe 33. The top opening of the water inlet pipe 33 is adapted to the left end of the diverter 5.

[0031] The device is also designed with a one-way plate 2 14 located on the rear side of the outer surface of the drain 5, and the direction of the serrated slope is opposite to that of the one-way plate 1 13, so that the connecting plate 21 and the clamping strip 22 can move to the left along the surface of the one-way plate 2 14, but cannot move to the right. By removing the puncture needle 12, the left head of the drain 5 is abutted against the sealing ring 35, and the limiting ring 34 is driven to move downward to the deep inner cavity of the water inlet pipe 33, and the spring 1 36 is compressed to squeeze and deform the sealing ring 35, and provide a sealing between the drain 5 and the limiting ring 34. The disinfectant in the disinfectant storage tank 32 is pumped into the inner cavity of the drain 5 by the water pump 31. When the piston 15 is subjected to the high pressure from the disinfectant, the predetermined position is maintained by the abutment between the card strip 22 and the serrations of the one-way plate 2 14, which helps the liquid through port 24 to coincide with the drain pipe 1 9, the drain pipe 2 10 or the drain pipe 3 11, so that the high-pressure disinfectant passes through the liquid through port 24 through one of the drain pipes 1 9, the drain pipe 2 10 and the drain pipe 3 11 for centralized flushing each time, which helps to efficiently clean the equipment.

[0032] The right end of the flow diverter 5 is fixedly connected with a handle 7, and the right side of the inner wall of the handle 7 is provided with a plurality of groups of circular protrusions of different sizes, which are made of rubber blocks;

[0033] The handle 7 is convenient for the user to hold the drain device 5, and the multiple groups of circular protrusions on the inner wall can provide flexible buffer support by abutting against the palm of the hand, which is ergonomic.

[0034] The piston 15 is in a dumbbell shape, and both ends of the piston 15 are in interference fit with the inner wall of the flow guider 5;

[0035] The dumbbell-shaped design of the piston 15 enables it to move in a sealing manner on the inner wall of the drain 5 , thereby providing a corresponding seal for the ascites entering the inner cavity of the drain 5 .

[0036] The mounting ring 19 is in the shape of a circular ring, and the mounting ring 19 can slide along the surface of the flow guider 5;

[0037] The mounting ring 19 is fixedly connected to the connecting block 18 and slides along the surface of the diverter 5. The outer surface of the mounting ring 19 is movably sleeved with a slip ring 20 so that the slip ring 20 can rotate around the axis of the mounting ring 19, so that the connecting plate 21 and the clamping strip 22 can freely switch positions according to the working needs of the equipment.

[0038] Among them, the inner diameters of the drain pipe 1 9, the drain pipe 2 10 and the drain pipe 3 11 increase from left to right, the width of the liquid passage 24 is equal to the inner diameter of the drain pipe 3 11, and the drain pipe 1 9, the drain pipe 2 10 and the drain pipe 3 11 are all connected to the inner cavity of the drainage device 5;

[0039] like Figure 4 As shown, the inner diameters of the drain tube 1 9, the drain tube 2 10 and the drain tube 3 11 increase in sequence, which means that as the piston 15 moves further to the right, the pressure of the ascites becomes greater, and thus a larger passing area is required to ensure the smoothness of the drainage work. The device distributes the drain tube 1 9, the drain tube 2 10 and the drain tube 3 11 according to the displacement generated by the piston 15 compressing the spring 2 17. When the piston 15 drives the sealing cylinder 23 to make the liquid passage 24 coincide with the drain tube 3 11, it means that the spring 2 17 is compressed to the maximum extent, that is, the rebound force generated is the maximum, and the ascites pressure on the piston 15 is also the maximum. At this time, the drain tube 3 11 with the largest area is just used to provide a channel for the drainage of a large amount of ascites. When the ascites water pressure is small, the compressed stroke of the spring 2 17 is used to confirm, and the piston 15 and the sealing cylinder 23 are driven to automatically move to a position that coincides with the drain tube 2 10 or the drain tube 1 9, thereby achieving automatic switching of the drainage channel area.

[0040] Among them, the one-way plate 1 13 and the one-way plate 2 14 are both serrated, and the serration directions of the one-way plate 1 13 and the one-way plate 2 14 are opposite. The front and rear sides of the bottom of the outer surface of the flow guider 5 are fixedly connected to the limit blocks 8, and the top surfaces of the two groups of limit blocks 8 form an angle of 210°, and the bottom of the connecting plate 21 abuts against the top of the limit blocks 8;

[0041] The serrated shapes of the one-way plate 13 and the one-way plate 2 14 are opposite. During the rotation of the clamping strip 22, it is possible to flexibly choose to perform drainage operation using automatic ascites pressure, or to disinfect and clean the drainage tube 1 9 , the drainage tube 2 10 , the drainage tube 3 11 and the corresponding hose 4 .

[0042] The piston 15 can move rightward in the inner cavity of the flow diverter 5 to the rightmost side of the flow diverter 5 and abut against the right side of the inner wall of the flow diverter 5. At this time, the spring 17 is compressed to the maximum extent.

[0043] When the piston 15 moves to the far right, it is confirmed that the ascites pressure used for drainage by the device is the maximum, which is confirmed by the maximum stroke of the spring 2 17 being compressed.

[0044] Working principle:

[0045] First, connect the three sets of hoses 4 to the drainage pipe 1 9, the drainage pipe 2 10 and the drainage pipe 3 11 respectively, rotate the slip ring 20, and drive the connecting plate 21 and the clamping strip 22 to rotate to the first position, that is, the surface of the one-way plate 1 13 (Note: the clamping strip 22 is located on the surface of the one-way plate 1 13 as the first position, when the connecting plate 21 and the clamping strip 22 rotate to the surface of the one-way plate 2 14, it is the second position), hold the handle 7, hold the front side of the drainage device 5 at the same time, move the drainage device 5, and puncture the puncture needle 12 into the patient's abdomen. At this time, the ascites enters the left side of the inner cavity of the piston 15 along the puncture needle 12;

[0046] Then, the ascites rapidly fills the sealing cylinder 23 under the action of the intra-abdominal pressure and seals against one end of the piston 15. At this time, the intra-abdominal pressure acts on one end of the piston 15 through the ascites. Figure 4 As shown, the piston 15 moves to the right under the pressure of the ascites and continues to compress the spring 2 17. At this time, the connecting block 18, the mounting ring 19, the slip ring 20, the connecting plate 21 and the clamping strip 22 are synchronously driven to move to the right. Figure 3 As shown, when the clamping strip 22 moves relative to the one-way plate 13, it is abutted by the inclined surface of the sawtooth of the one-way plate 13 and drives the connecting plate 21 to bend outward until the clamping strip 22 is re-engaged in the sawtooth groove on the surface of the one-way plate 13. This design prevents the clamping strip 22 from being reset to the left without being affected by external force when it moves to the right, and maintains the established position of the connecting plate 21 and the clamping strip 22 after movement. After the pressure generated by pushing the piston 15 and compressing the spring 2 17 is equal according to the size of the abdominal cavity water pressure, the piston 15 stops moving. When the amount of abdominal cavity water is large, the piston 15 drives the sealing cylinder 23 and the liquid through port 24 to move to the drainage pipe 2 10 or the drainage pipe 3 11, so that the liquid through port 24 coincides with it. At this time, the abdominal cavity Water can be discharged into the liquid storage tank 2 along the drainage pipe 2 10 or the drainage pipe 3 11. When the amount of water in the abdominal cavity is small, the water pressure is also small, so the displacement generated by the piston 15 compressing the spring 2 17 is minimal. At this time, the displacement of the sealing cylinder 23 driven to the right by the piston 15 is minimal, that is, the liquid port 24 only overlaps with the drainage pipe 1 9. At this time, it is suitable for the ascites to be discharged with a small flow rate. After the ascites is drained, the user can rotate the slip ring 20 and drive the connecting plate 21 and the clamping strip 22 to rotate 90° around the axis of the drain 5 toward the second position, so that the connecting plate 21 and the clamping strip 22 rotate to the top of the drain 5. At this time, the clamping strip 22 loses the limit of the one-way plate 13 and is reset under the action of the spring 2 17.

[0047] Finally, the disposable puncture needle 12 is removed from the left head of the drain device 5. At the same time, the drain device 5 is turned vertically downward as a whole, and its left head (after the drain device 5 changes its position, the left head becomes the bottom) is aligned with the top opening of the water inlet pipe 33 and abuts against the sealing ring 35, and the limiting ring 34 and the sealing ring 35 are pressed downward, and the spring 1 36 is compressed to make the bottom opening of the drain device 5 abut against the limiting ring 34 and form a seal. Then, the water pump 31 is turned on, and the disinfectant in the disinfectant storage tank 32 is pumped into the inner cavity of the water inlet pipe 33 and upward into the inner cavity of the drain device 5. At this time, since the drainage pipe 1 9, the drainage pipe 2 10 and the drainage pipe 3 11 all need to be cleaned, in order to concentrate the water pressure, the slip ring 20 is rotated, and the connecting plate 21 and the clamping strip 22 are driven to rotate to the second position, as shown in FIG. Figure 2 As shown, when in position No. 2, the piston 15 drives the connecting plate 21 and the clamping strip 22 to move only from right to left, but not in the opposite direction. This is because the direction of the sawtooth slope of the one-way plate 2 14 is opposite to that of the one-way plate 1 13. When it is necessary to clean any one of the drain pipe 1 9, the drain pipe 2 10 or the drain pipe 3 11, the sliding ring 20 is moved to move the clamping strip 22 to the position between the liquid passage 24 and the drain pipe 1 9 or the drain pipe 2 10 or the drain pipe 3 11. The elastic force from the spring 2 17 is offset by the squeezing force between the clamping strip 22 and the sawtooth slope of the one-way plate 2 14. The disinfectant generates high pressure under the action of the water pump 31 and quickly passes through the inner cavity of the hose 4, one end of the piston 15 and any one of the drain pipe 1 9 or the drain pipe 2 10 or the drain pipe 3 11. After cleaning, the mixed liquid is discharged into the liquid storage tank 2 through the hose 4.
