TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to an ascites drainage control device. BACKGROUND

[0002] In clinical medicine, ascites is a common symptom caused by liver cirrhosis, liver cancer, abdominal infection and other diseases. When the amount of ascites is too much, it will cause the patient to have abdominal distension, dyspnea, abdominal cavity pressure rise and other discomforts, seriously affecting the patient's quality of life, and even endangering life. At this time, ascites drainage is needed to drain the excess fluid in the abdominal cavity to relieve the patient's symptoms and control the progression of the disease.

[0003] The ascites drainage equipment commonly used in clinical medicine is composed of a drainage tube, a drainage bag or a drainage ball, and has the following defects: first, the drainage flow rate is difficult to control, and too fast flow rate can easily cause the abdominal cavity pressure of the patient to drop suddenly, causing complications such as hypotension and hepatic encephalopathy, and too slow flow rate cannot relieve the symptoms in time, and the traditional equipment lacks a convenient flow rate adjusting mechanism, so medical staff need to adjust by folding the drainage tube or changing the type of drainage tube, which is cumbersome to operate; second, during the drainage process, the drainage tube is easily blocked by blood clots, fibrous tissue and other substances in the abdominal cavity, and once blocked, the drainage tube needs to be replaced or cleared with additional equipment, which not only increases the patient's pain and medical costs, but also may affect the drainage effect and delay the disease if not cleared in time; third, the control components of the existing drainage equipment are made of hard and heavy materials, which are not comfortable to wear, and lack effective fixing mechanisms, so when the patient is out of bed, the drainage tube is easily pulled and displaced, and even causes the drainage tube to come out, causing the risk of infection and bleeding, and when in bed, the tube lacks orderly restraint and is easily folded and entangled with the patient's turning over and body position adjustment, resulting in poor drainage or tube damage; fourth, the stability of some adjusting mechanisms is insufficient, and the adjusting state is easily changed due to the patient's body position change and slight collision, affecting the safety of drainage.

[0004] In view of the above problems of the prior art, the present application provides an ascites drainage control device to solve the problems of inconvenient flow rate control, easy tube blockage, uncomfortable wearing, poor fixation and insufficient adjustment stability, and to improve the safety, convenience and comfort of ascites drainage.

The control assembly 1 is made of light material (such as medical ABS, polyethylene, etc.), which can reduce the weight feeling when worn, improve the comfort of the patient, and avoid the displacement risk caused by the excessive weight of the material pulling the drainage tube. The control assembly 1 comprises a support seat 4, a shell 5 is installed on the support seat 4, the shell 5 is internally hollow, provides installation and movement space for the folding pipe 8 and each transmission part, guarantees the cooperative operation of the parts, a first adjusting assembly 6 is installed at the front end of the shell 5, a second adjusting assembly 7 is installed at the rear end of the shell 5, the folding pipe 8 for drainage is installed in the shell 5, the folding pipe 8 is made of medical elastic material, can realize stretching and deformation, is convenient for adjusting the flow rate and completing the dredging operation through structural change; the front end of the folding pipe 8 movably penetrates the first adjusting assembly 6 and is connected with the first drainage pipe 2, the rear end of the folding pipe 8 movably penetrates the second adjusting assembly 7 and is connected with the second drainage pipe 3, and the continuity of the drainage channel is ensured.

[0027] The first adjusting assembly 6 and the second adjusting assembly 7 are the same in structure, the first adjusting assembly 6 comprises a first installation cap 9, a fixed ring 10, a rotating roller 11, a first gear 12 and a second gear 13, the first installation cap 9 is installed at the front end of the shell 5, the shell 5 supports the first installation cap 9, ensures that the assembly is firmly installed, the fixed ring 10 is installed in the first installation cap 9, the rotating roller 11 penetrates the fixed ring 10 and is movably connected with the fixed ring 10, the fixed ring 10 supports and positions the rotating roller 11, ensures that the rotating roller 11 can only rotate along the axis thereof, and avoids deviation from affecting the transmission accuracy; the first gear 12 is installed on the front end outer side wall of the rotating roller 11 and rotates synchronously with the rotating roller 11, the second gear 13 is movably installed on the side wall of the fixed ring 10, the first gear 12 and the second gear 13 are meshed and connected, power transmission is realized, and the front end of the folding pipe 8 penetrates the rotating roller 11, the first gear 12 and the center of the first installation cap 9 in sequence; It should be noted that the rotating roller 11 can drive the first gear 12 to rotate when rotating, and the first gear 12 drives the second gear 13 meshed therewith to rotate.

[0028] The second gear 13 is installed with a blocking plate 14, a magnetic part one 15 is installed on the outer side wall of the blocking plate 14, a magnetic part two is installed on the inner side wall of the first installation cap 9 close to the magnetic part one 15, and the magnetic part one 15 and the magnetic part two are magnetically different; It should be noted that the second gear 13 can drive the blocking plate 14 to rotate, and the blocking plate 14 can extrude and seal the folding pipe 8 extending out of the rotating roller 11 when rotating, in this process, the magnetic part one 15 and the magnetic part two are magnetically attracted, when the blocking plate 14 stops moving, the magnetic part two can adsorb and fix the blocking plate 14, guarantees the stability of the blocking state, the adsorption force of the magnetic part can stably adsorb the blocking plate 14, avoids displacement of the blocking plate 14 due to liquid impact force and change of the patient's body position, guarantees the stability of the flow rate, at the same time, can realize positioning after flow rate adjustment, and improves the adjustment accuracy.

[0029] The housing 5 has a slot 16, which is positioned opposite to the support base 4. The slot 16 provides guidance and space for the movement of the push plate 17, ensuring that the push plate 17 moves along the set trajectory and avoiding deviation that affects the extension and adjustment effect of the folding tube 8.

[0030] A push plate 17 is installed on the folded tube 8. The push plate 17 is fixedly connected to the folded tube 8 and can drive the folded tube 8 to extend and retract. A mounting seat 18 is installed on the push plate 17. The mounting seat 18 is movably engaged in the slot 16 to achieve a sliding fit between the mounting seat 18 and the housing 5. A telescopic rod 19 is movably installed on the mounting seat 18. A mounting groove 20 is opened at the end of the telescopic rod 19 away from the mounting seat 18. An insert rod 21 is movably installed in the mounting groove 20. The lower end of the insert rod 21 extends out of the lower end of the telescopic rod 19, and the upper end of the insert rod 21 extends out of the upper end of the telescopic rod 19.

[0031] A pressing member 22 is installed at the upper end of the insertion rod 21. A spring 23 is installed between the pressing member 22 and the telescopic rod 19. The spring 23 provides the reset force for the insertion rod 21, ensuring that the insertion rod 21 can automatically reset and disengage from the spiral groove 25 when the pressing member 22 is released after pressing. A ball bearing 24 is movably installed at the lower end of the insertion rod 21. The ball bearing 24 is made of medical stainless steel to reduce friction loss.

[0032] The outer wall of the rotating roller 11 is provided with a spiral groove 25. The trajectory design of the spiral groove 25 can convert the linear motion of the telescopic rod 19 into the rotational motion of the rotating roller 11, thereby achieving efficient power transmission. The insertion rod 21 can be movably engaged in the spiral groove 25. When the insertion rod 21 is inserted into the spiral groove 25, the ball bearing 24 is placed in the spiral groove 25. The placement of the ball bearing 24 can reduce the friction between the insertion rod 21 and the spiral groove 25, reduce component wear, and at the same time make the movement smoother and avoid jamming that affects operation. It should be noted that when the liquid flow rate in the drainage tube is too high, the telescopic rod 19 is in a compressed state. Manually moving the push plate 17 along the slot 16 towards the first adjustment component 6 compresses the folded tube 8, reducing its diameter and initially lowering the liquid flow rate. Then, the telescopic rod 19 is stretched to the position of the spiral groove 25, and the pressing member 22 is pressed down. The pressing member 22 compresses the spring 23, causing the insertion rod 21 to move downwards. After the insertion rod 21 is inserted into the spiral groove 25, the telescopic rod 19 is stretched further. 9. The insertion rod 21 moves along the spiral groove 25, driving the rotating roller 11 to rotate. The rotating roller 11 drives the first gear 12 to rotate, and the first gear 12 drives the second gear 13 meshing with it to rotate. The second gear 13 drives the sealing plate 14 to rotate. When the sealing plate 14 rotates, it can squeeze the folded tube 8 extending from the rotating roller 11, further reducing the flow rate of the liquid. When the sealing plate 14 stops moving, the magnetic component 15 and the magnetic component 2 are attracted and can be attracted and fixed to the sealing plate 14 to maintain the current flow rate stability.

[0033] When the drainage tube is blocked by blood clots or fibrous tissue, the telescopic rod 19 is stretched along the slot 16 towards the first adjusting component 6 until it reaches the position of the spiral groove 25. At this time, the folded tube 8 is in the unfolded state. Press down the pressing member 22, which compresses the spring 23, causing the insertion rod 21 to move downward. After the insertion rod 21 is inserted into the spiral groove 25, continue to stretch the telescopic rod 19. The insertion rod 21 moves along the spiral groove 25, causing the rotating roller 11 to rotate. The rotating roller 11 drives the first gear 12 to rotate, and the first gear 12 drives the second gear 13, which meshes with it, to rotate. The second gear 13 drives the sealing plate 14 to rotate. When the sealing plate 14 rotates, it can squeeze the folded tube 8 that extends out of the rotating roller 11 to seal the pipe. The sealing plate 14 stops moving, and the magnetic component 15 and the magnetic component 2 are attracted to each other. The magnetic component 2 attracts and fixes the sealing plate 14. Then, the push plate 17 is manually driven to move along the slot 16 towards the direction close to the first adjustment component 6. The folded tube 8 is compressed, and the liquid in the folded tube 8 forms instantaneous pressure, which pushes the liquid in the second drainage tube 3 to be discharged faster. The liquid impact force is used to clear the blood clots or fibrous tissue in the second drainage tube 3. Then the telescopic rod 19 retracts in the opposite direction, the insertion rod 21 moves in the opposite direction along the spiral groove 25, driving the rotating roller 11 to rotate in the opposite direction, the rotating roller 11 drives the first gear 12 to rotate in the opposite direction, the first gear 12 drives the second gear 13 meshing with it to rotate in the opposite direction, the second gear 13 drives the sealing plate 14 to rotate in the opposite direction, and the sealing plate 14 releases the pressure on the front end of the folded tube 8. Then, the pressing member 22 is pulled out from the spiral groove 25, keeping the push plate 17 in place and the folding tube 8 still in a compressed state. The telescopic rod 19 is rotated 180 degrees, and then the telescopic rod 19 is stretched along the slot 16 towards the second adjustment component 7 until the telescopic rod 19 is stretched to the position of the spiral groove 25 of the second adjustment component 7. The pressing member 22 is pressed down, the pressing member 22 squeezes the spring 23, and drives the insertion rod 21 to move down. After the insertion rod 21 is inserted into the spiral groove 25, the telescopic rod 19 is stretched further. The insertion rod 21 moves along the spiral groove 25, driving the rotating roller 11 to rotate. The rotating roller 11 drives the second adjustment component 7 to rotate. When gear 12 rotates, it drives gear 13, which meshes with it, to rotate. Gear 13 drives sealing plate 14 to rotate. When sealing plate 14 rotates, it can squeeze the folded tube 8 extending from rotating roller 11 until the pipe is sealed. When sealing plate 14 stops moving, magnetic component 15 and magnetic component 2 are attracted to each other. Magnetic component 2 can attract and fix sealing plate 14. Then, folded tube 8 is stretched, and negative pressure is formed inside folded tube 8. It generates an adsorption force on the liquid in first drainage tube 2, accelerates the discharge of liquid, and uses negative pressure and liquid impact force to clear blood clots or fibrous tissue in first drainage tube 2.

[0034] Reverse the telescopic rod 19 to reset the sealing plate 14, remove the seal, and restore normal drainage.

[0035] The housing 5 has marking lines on both sides. The marking lines are located at the starting position of the spiral groove 25. When the insertion rod 21 moves to the marking line, the insertion rod 21 can be quickly aligned and inserted into the spiral groove 25 without repeated positioning, which improves the efficiency of operation and reduces the difficulty of operation for medical staff. It is especially suitable for flow rate adjustment and pipeline dredging in emergency situations.

[0036] The bottom wall of the support base 4 is equipped with a fixing buckle 26; the fixing buckle 26 adopts an adjustable elastic buckle structure to adapt to clothing of different thicknesses. When the patient gets out of bed, the control component 1 and the drainage tube can be fixed to the clothing through the fixing buckle 26 to prevent the drainage tube from being pulled, displaced or dislodged, ensuring the continuous and stable drainage process, while improving the patient's freedom of movement.

[0037] The specific usage is as follows: Verify the integrity of the device, including control component 1, first drainage tube 2, second drainage tube 3, and drainage ball. Check that the folded tube 8 is undamaged and has good elasticity, the gear transmission is smooth, the magnetic components are properly attracted, the spring 23 returns flexibly, the ball bearing 24 is not stuck, and the fixing buckle 26 has adequate elasticity. Perform standardized aseptic disinfection on control component 1, drainage tubes, and drainage ball to meet the aseptic requirements for clinical surgery. Securely connect one end of the first drainage tube 2 to the front adjustment component of control component 1, leaving an appropriate length at the other end for abdominal puncture placement. Connect one end of the second drainage tube 3 to the rear adjustment component of control component 1, and connect the other end to the drainage ball, ensuring that all interfaces are sealed without leakage. Ensure that the telescopic rod 19 is in a compressed state, the insertion rod 21 is disengaged from the spiral groove 25, the sealing plate 14 does not compress the folded tube 8, and the drainage channel remains unobstructed.

[0038] Place the support base 4 of the control component 1 stably in a comfortable position on the patient's abdomen or flank, ensuring that the slot 16 of the housing 5 faces for easy operation. The support base 4 itself provides stability and prevents displacement during turning without additional fixation. Arrange the first drainage tube 2 and the second drainage tube 3 in an orderly manner, relying on the support base 4, ensuring the drainage ball is placed below the abdominal cavity, conforming to the principle of gravity drainage. Observe the fluid flow rate at the beginning of drainage. If the flow rate is too fast, first push the push plate 17 towards the first adjustment component 6 to compress the folded tube 8 for initial speed control. Then, extend the telescopic rod 19 to the marked line on the housing 5. Press down the pressure member 22 to insert the insertion rod 21 into the spiral groove 25, continue to stretch the telescopic rod 19 to drive the sealing plate 14 to squeeze the folded tube 8 until the flow rate is suitable, release the pressure member 22, and the magnetic part will attract and fix the sealing plate 14 to complete the adjustment; before the patient turns over or adjusts his / her position, gently hold the control component 1 to keep the position stable, and after turning over, frequently check the placement of the tube, relying on the support base 4 and the shell 5 to constrain the tube to avoid tube stacking and bending, so that the drainage can be kept smooth without frequent adjustments; if the drainage is interrupted or the flow rate suddenly decreases, operate according to the sealing and unblocking steps in the technical plan, reset the device after unblocking, and restore normal drainage.

[0039] The control component 1 is fixed to the appropriate position of the patient's clothing waistband by the fixing buckle 26 on the bottom wall of the support base 4, ensuring that it is secure and does not loosen, and does not compress the skin, so as to avoid pulling during movement; the drainage ball is fixed to the lower outer side of the clothing to ensure that gravity drainage is not affected.
