Description

Technical Field

[0001] The invention relates to the technical field of ascites drainage, and more specifically, to a special ascites drainage device used in clinical gastroenterology. Background Art

[0002] Ascites is a type of localized edema, which refers to the accumulation of excessive fluid in the abdominal cavity. Under normal circumstances, there is a small amount of fluid in the abdominal cavity, which lubricates the intestines. When the amount of fluid exceeds a certain limit in any pathological state, it is called ascites. There are many reasons for ascites. In clinical gastroenterology, it is mainly caused by liver disease, gastrointestinal inflammation, tumors or other diseases related to the digestive system, which can cause abdominal distension, difficulty breathing, renal failure and other problems. During treatment, the ascites in the abdominal cavity needs to be drained and cleared. Usually, the pressure in the abdominal cavity itself is used to make the ascites generate outward pressure. A small hole is opened on the side of the abdominal cavity to insert a drainage catheter. Under the abdominal cavity pressure, the ascites automatically drains out through the drainage catheter.

[0003] However, during ascites drainage, there is a gap between the inserted drainage tube and the small hole in the abdomen, resulting in poor drainage sealing. Under the pressure in the abdominal cavity, ascites is likely to overflow from the gap between the outside of the drainage tube and the small hole, which may cause the internal pressure of the abdominal cavity to weaken and the ascites cannot be drained further. Moreover, during intubation drainage, when replacing the sealed bottle containing ascites, the drainage tube needs to be put back into the empty sealed bottle. During the process of transferring the drainage tube, the ascites is still in a drainage state, which may easily cause the ascites to leak out and fall to the ground to pollute the environment. The drainage tube cannot be closed during the transfer. Summary of the invention

[0010] 1. In the present invention, the cannula is inserted into the small hole and connected to the abdomen, and then the rotating ring is manually rotated to make the expansion mechanism expand outward under the support of the plastic tube, so that the expansion mechanism forms an expansion squeezing force on the inner wall of the small hole. At the same time, because the expansion mechanism is longer than the thickness of the abdomen, the expansion and blocking of the outlet end of the small hole in the abdomen is prevented from forming a gap between the small hole and the drainage tube to prevent the pressure in the abdominal cavity from leaking out, and to avoid the formation of a gap to prevent ascites from overflowing from the gap.

[0011] 2. Manually rotate the plastic ring outward. During expansion, the spring is compressed under the support of the support block, so that the arc plate squeezes the pressure plate outward, and then the pressure plate drives the force rod to expand the deformation tube outward. During expansion, the left and right sides of the exit end of the abdominal cavity are small holes and the abdominal cavity. When the small hole is expanded and filled, the abdominal muscle tissue squeezes and blocks the expansion. At the same time, the force rod at the exit end of the abdominal cavity does not contact the abdominal muscle tissue, and then is not blocked and compressed by the pressure plate position. The exit end position expands more than the small hole, forming a blocking effect, so that the ascites can only be diverted out from the needle, avoiding the formation of gaps that cause the pressure in the abdominal cavity to leak out and affect the diversion.

[0012] 3. In the present invention, the plastic block is pressed manually to drive the bending plate to compress the guide tube. At the same time, the sealing plate is driven by the plastic block to be compressed and deformed outward, and then the bending plate is compressed to a flat state by the two plastic blocks. Under the pressure of the arc strip and the elastic force of the deformation plate, the outer side of the guide tube is divided into two parts of continuously bent flat states, which are squeezed and matched with each other, so that the guide tube blocks the ascites from continuing to flow and prevents the generation of gaps. After the collecting bottle is filled with ascites, the guide tube is quickly closed to avoid leakage when the outlet end of the guide tube needs to be transferred. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings: Example

[0022] As attached Figure 1 To Attachment Figure 5 As shown: The present invention discloses a special device for ascites drainage in the clinical gastroenterology department, and the structure thereof comprises a cannula 1, a needle 2, a collecting bottle 3, a blocking block 4, a guide tube 5, and a ventilating tube 6. The cannula 1 is embedded and fixed on the outside of the guide tube 5, the needle 2 pipeline is connected to the outermost end of the guide tube 5, the ventilating tube 6 is embedded and fixed on the outside of the guide tube 5, the blocking block 4 is installed on the outside of the lower end of the guide tube 5, the blocking block 4 is located at the upper end of the collecting bottle 3, the cannula 1 is provided with a flow tube 11, a rotating ring 12, a support plate 13, a plastic The material tube 14 and the expansion mechanism 15 are provided. The support plate 13 is embedded in the side of the plastic tube 14, and the expansion mechanism 15 is embedded in the inner side of the plastic tube 14. The rotating ring 12 is installed on the inner side of the plastic tube 14. The inner side of the rotating ring 12 is embedded in the side of the expansion mechanism 15. The expansion mechanism 15 is limited and slidably matched with the outer side of the flow tube 11. The support plate 13 is installed on the outer side of the guide tube 5. The left and right ends of the flow tube 11 are embedded in the guide tube 5. The flow tube 11 is a cylindrical structure, and It is made of plastic with a certain hardness and has an indented annular groove on the outside, so that the needle 2 breaks the skin and is inserted into the abdomen, thereby creating a small hole in the abdomen for the outflow of ascites, so that the cannula 1 is located in the small hole, and the ascites flows outward from the needle 2 into the flow tube 11 in the cannula 1 under internal pressure, and then the ascites is diverted outward through the guide tube 5 under pressure, and the ventilation tube 6 disperses the bubbles in the guide tube 5, so that the ascites passes through the blocking block 4 connected to the guide tube 5 and enters the collection bottle 3 for collection. To achieve the effect of guiding the outflow of ascites, when the cannula 1 is in the small hole, the rotating ring 12 is manually rotated to make the expansion mechanism 15 expand outward under the support of the plastic tube 14, so that the expansion mechanism 15 forms an expansion squeezing force on the inner wall of the small hole. At the same time, because the expansion mechanism 15 is longer than the thickness of the abdomen, the expansion and blocking of the outlet end of the small hole in the abdomen is prevented from forming a gap between the small hole and the guide tube 5 to cause the pressure in the abdominal cavity to leak out, and to avoid the formation of a gap to cause ascites to overflow from the gap.

[0023] The expansion mechanism 15 is provided with a support block w1, a plastic ring w2, a deformation tube w3, a slider w4, and a dislocation structure w5. The support block w1 is embedded in the outer end of the side of the dislocation structure w5. The outer side of the dislocation structure w5 is installed on the inner side of the deformation tube w3. The deformation tube w3 is attached to the inner side of the support block w1. The slider w4 is embedded in the outer side of the plastic ring w2. The slider w4 is movably matched with the dislocation structure w5. The support block w1 is embedded in the inner side of the plastic tube 14. The plastic ring w2 is limited and slidably matched with the outer side of the circulation tube 11. The plastic ring w2 is embedded in the side of the rotating ring 12. The dislocation structure w5 There are four of them, which are evenly distributed in a ring shape. The deformation tube w3 is made of rubber and has the characteristic of being easily deformed and stretched, so that the plastic ring w2 rotates with the rotating ring 12, and then the slider w4 squeezes the inner side of the dislocation structure w5, pushing the dislocation structure w5 to move the deformation tube w3 outward, so that the deformation tube w3 is deformed and squeezed toward the outer shape under the sealing and fixation of the support block w1 and the inner side of the plastic tube 14, so as to achieve the effect of making the deformation tube w3 expand outward as a whole, and then the rotating ring 12 is rotated again to drive the slider w4 to disengage from the support of the dislocation structure w5, so that the deformation tube w3 rebounds inward, and then a gap is generated between the outer side of the plastic tube 14 and the small hole for easy pulling out.

[0024] The dislocation structure w5 is provided with a spring w51, an arc plate w52, a pressure plate w53, and a force rod w54. The force rod w54 is embedded in the left and right sides of the pressure plate w53. The spring w51 is installed on the outer sides of the left and right ends of the arc plate w52. The pressure plate w53 is attached to the outer side of the arc plate w52. The force rod w54 is installed on the inner side of the deformation tube w3. The support block w1 is embedded in the outer end of the spring w51. The pressure plate w53 is made of rubber and has the characteristics of compression deformation. The force rod w54 and the pressure plate w53 are arranged in an interval distribution state, so that the spring w51 is supported on the support block w1. With the support of block w1, the arc plate w52 squeezes the pressure plate w53 outward, and then the pressure plate w53 drives the force-bearing rod w54 to expand the deformable tube w3 outward. During expansion, the left and right sides of the exit end at the abdominal cavity are small holes and the abdominal cavity. When the small hole is expanded and filled, the abdominal muscle tissue squeezes and blocks the expansion. At the same time, the force-bearing rod w54 at the exit end of the abdominal cavity does not contact the abdominal muscle tissue, and then the position of the pressure plate w53 is not blocked and compressed. The exit end position expands more than the small hole, forming a blocking effect, so that the ascites can only be diverted out from the needle 2, avoiding the formation of a gap that causes the pressure in the abdominal cavity to leak out and affect the diversion.

[0025] Among them, the rotating ring 12 is provided with a bearing ring t1, a limit plate t2, and a ball t3. The bearing ring t1 is limited and slidably matched on the inner side of the ball t3, and the bearing ring t1 is engaged on the outer side of the limit plate t2. The outer end of the ball t3 is installed on the inner side of the plastic tube 14, and the right end of the ball t3 is embedded with the side of the expansion mechanism 15. The left side of the limit plate t2 is in an outward protruding state, and the surface of the protruding part is relatively rough. Therefore, the outer end of the limit plate t2 is manually rotated to make the bearing ring t1 on the outer side of the limit plate t2 slide and rotate on the inner side of the ball t3, and at the same time, the plastic ring w2 in the expansion mechanism 15 is driven to rotate, so that the expansion mechanism 15 expands outward. The specific usage and function of this embodiment are as follows: In the present invention, the needle 2 breaks the skin and is inserted into the abdomen, thereby forming a small hole in the abdomen for the outflow of ascites, so that the cannula 1 is located in the small hole, and the ascites flows outward from the needle 2 into the flow tube 11 in the cannula 1 under internal pressure, and then the ascites is diverted outward through the diversion tube 5 under pressure, and the ventilation tube 6 disperses the bubbles in the diversion tube 5, so that the ascites enters the collection bottle 3 through the blocking block 4 connected to the diversion tube 5 for collection, thereby achieving the effect of guiding the outflow of ascites, and then when the cannula 1 is in the small hole, the rotating ring 12 is manually rotated to make the expansion mechanism 15 expand outward under the support of the plastic tube 14, so that the expansion mechanism 15 forms an expansion squeezing force on the inner wall of the small hole, and at the same time, because the expansion mechanism 15 is longer than the thickness of the abdomen, the expansion and interception of the outlet end of the small hole in the abdomen on the outside of the expansion mechanism 15 prevents the formation of a gap between the small hole and the diversion tube 5 to cause the pressure in the abdominal cavity to leak out, and avoids the formation of a gap to cause ascites to overflow from the gap.

[0026] In the present invention, the outer end of the limit plate t2 in the rotating ring 12 is manually rotated, so that the bearing ring t1 outside the limit plate t2 slides and rotates inside the ball t3, and the rotation drives the plastic ring w2 in the expansion mechanism 15 to rotate and move. Then, after the plastic ring w2 rotates, it drives the slider w4 to squeeze the inner side of the dislocation structure w5, and pushes the dislocation structure w5 to move the deformation tube w3 outward, so that the deformation tube w3 is deformed and squeezed toward the outer shape under the sealing and fixation of the support block w1 and the inner side of the plastic tube 14, so as to achieve the effect of making the deformation tube w3 expand outward as a whole. Then, after the rotating ring 12 is rotated again, the slider w4 is driven to break away from the support of the dislocation structure w5, so that the deformation tube w3 rebounds inward, and a gap is generated between the outer side of the plastic tube 14 and the small hole. The gap is convenient for pulling out, and when the plastic ring w2 is rotated to expand outward, the spring w51 is compressed under the support of the support block w1, so that the arc plate w52 squeezes the pressure plate w53 outward, and then the pressure plate w53 drives the force-bearing rod w54 to expand the deformable tube w3 outward. During expansion, the left and right sides of the outlet end at the abdominal cavity are small holes and the abdominal cavity. When the small hole is expanded and filled, the abdominal muscle tissue squeezes and blocks the expansion. At the same time, the force-bearing rod w54 at the outlet end of the abdominal cavity does not contact the abdominal muscle tissue, and then the position of the pressure plate w53 is not blocked and compressed. The outlet end position expands more than the small hole, forming a blocking effect, so that the ascites can only be diverted out from the needle 2, avoiding the formation of a gap that causes the pressure in the abdominal cavity to leak out and affect the diversion.

[0028] The bending plate s1 is provided with an arc strip s11, an elastic plate s12, and a deformation plate s13. The arc strip s11 is embedded in the inner side of the elastic plate s12. The elastic plate s12 is installed on the left and right sides of the deformation plate s13. The deformation plate s13 is embedded in the inner side of the plastic block s2. The inner side of the deformation plate s13 is an arc structure and is made of rubber material. It has the characteristics of deformation elasticity. The two deformation plates s13 in the two plastic blocks s2 are one inwardly arcuate and the other outwardly arcuate, which have a matching The elastic plate s12 is made of aluminum alloy and has the characteristics of strong toughness and easy bending, so that the plastic block s2 pushes the deformation plate s13 to squeeze the outside of the guide tube 5, so that the elastic plate s12 wraps the outside of the guide tube 5 and expands outward, and then under the pressure of the arc strip s11 and the elastic force of the deformation plate s13, the outside of the guide tube 5 is divided into two parts in a continuously bent flat state, which are squeezed and matched with each other, so that the guide tube 5 blocks the ascites from continuing to flow, and at the same time, the two parts of the guide tube 5 are matched and squeezed with each other to prevent the formation of a gap.
