Description

Technical Field

[0001] The present invention relates to the technical field of drainage, and specifically to a hepatobiliary and pancreatic drainage device that is convenient for pressure adjustment. Background Technique

[0002] The suction drainage technique utilizes a device with suction power to effectively draw out inflammatory exudate, pus, blood, or digestive juice that leaks outside the digestive tract and has a tissue-damaging effect, which is free in a certain part of the body, creating important conditions for curing diseases or preventing the occurrence of complications. In the existing medical technology, the so-called hepatobiliary drainage device refers to a device that can effectively treat various hepatobiliary diseases caused by internal obstruction and congestion in the biliary tract and hepatic duct. By placing one end of the drainage tube into the body to discharge the body fluid congested in the hepatobiliary tract, the internal pressure of the hepatobiliary tract can be reduced, the physiological functions of the hepatobiliary tract can be restored, the pain of the patient can be effectively relieved, and the disease can be thoroughly treated. It is a device that plays an important role in the treatment of diseases.

[0003] The patent with the publication number CN214969823U discloses a hepatobiliary and pancreatic drainage device that is convenient for pressure adjustment, including a base. A protection component is arranged on the inner side wall of the base. The protection component includes a first arc-shaped plate, a spring, and a second arc-shaped plate. The drainage component includes a drainage bottle, a connecting tube, a micro air pump, an air suction tube, and a drainage tube. A fixing component is arranged on the drainage tube. The micro air pump provides power to suck the body fluid in the patient's body into the drainage bottle through the drainage tube, the air suction tube, and the connecting tube, reducing the pressure on the inside of the patient's hepatobiliary tract and relieving the pain of the patient. The first arc-shaped plate, the spring, and the second arc-shaped plate clamp and fix the drainage bottle. When the drainage bottle needs to be placed into the base, by placing the bottom of the drainage bottle between the two second arc-shaped plates and pushing the drainage bottle downward, the spring contracts under the action of force, so that the drainage bottle can be clamped between the two second arc-shaped plates. However, when the existing hepatobiliary and pancreatic drainage device with pressure adjustment is actually used, there are still many drawbacks. For example, the drainage bottle has no fixed structure, and it is easy to be knocked and broken during use, affecting the drainage effect and delaying the treatment of the patient, and the applicability is poor. Therefore, it is very necessary to design a hepatobiliary and pancreatic drainage device that is convenient for pressure adjustment. Summary of the Invention

[0004] The purpose of the present invention is to provide a hepatobiliary and pancreatic drainage device that is convenient for pressure adjustment to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A hepatobiliary and pancreatic drainage device that is convenient for pressure adjustment, comprising a base platform. A partition is fixedly connected inside the base platform. A fixing mechanism is arranged on the upper surface of the base platform. Fixing rods are fixedly connected to both sides of the upper surface of the base platform. A barrel-changing mechanism is arranged on the upper surface of the fixing rods. A cover plate is attached to the upper surface of the barrel-changing mechanism. A pressure control mechanism is arranged on the upper surface of the cover plate.

[0006] According to the above technical solutions, the fixing mechanism includes a sliding table and a support rod. The sliding table is fixedly connected to the upper surface of the base platform. The support rod is fixedly connected to the upper surface of the cover plate. Sliders are slidably connected to the upper surfaces of both ends of the sliding table. A sliding plate is fixedly connected to the upper surface of each slider. Fixing columns are fixedly connected to the opposite sides of the two sliding plates. A clamping block is fixedly connected to one end of each fixing column away from the sliding plate. A clamping plate is fixedly connected to the outer surface of each fixing column. A connecting rod is fixedly connected to the upper surface of the right clamping plate. A locking sleeve is fixedly connected to the upper surface of the connecting rod. Four locking plates are fixedly connected to the right side of the support rod. Hinge rods are arranged on the front and rear sides of the sliding table. A threaded rod passes through the middle of the partition. One end of the threaded rod is threadedly connected to a hinge plate. The other end of the threaded rod is fixedly connected to the output end of a motor. Both ends of each hinge rod are respectively hinged to the slider and the hinge plate. The locking sleeve is sleeved with the locking plate. A chute for the movement of the hinge rod is opened on the upper surface of the base platform. The four locking plates are arranged in a circular pattern. The hinge rod is rotatably connected to the sliding table. By starting an external motor, the threaded rod drives the hinge plate to move downward. When the hinge plate moves downward, it drives the sliders on the hinge rod to approach each other on the sliding table, causing the fixing columns connected to the sliding plates to move synchronously. The clamping plates on the fixing columns move towards the cover plate. The clamping blocks on the side of the clamping plate approach the edge of the cover plate, and then the drainage bucket and the cover plate are firmly fixed. When the clamping plate moves, it drives the locking sleeve on the connecting rod to move synchronously. The movement of the locking sleeve presses the locking plate to completely bind the catheter sleeved on the drainage tube. In this process, the drainage bucket can be firmly fixed on the placement tray, preventing the drainage bucket from shaking.

[0007] According to the above technical solution, the pressure control mechanism includes a drainage tube, the drainage tube is fixedly connected inside the support rod, one end of the drainage tube away from the support rod is fixedly connected with a protective cover, a shaft rod is rotatably connected to the upper surface of the protective cover, a hand valve is fixedly connected to the upper surface of the shaft rod, a special-shaped wheel is rotatably connected to the outer surface of the shaft rod, a telescopic column is slidably connected to the upper surface of the special-shaped wheel, a clamping ball is fixedly connected to the upper surface of the telescopic column, connecting columns are respectively fixedly connected to the upper and lower sides of the special-shaped wheel, a flow blocking block is attached to the outer surface of the special-shaped wheel, a flow control block is fixedly connected to the front end of the flow blocking block, a clamping plate is rotatably connected to the outer surface of each connecting column, ratchets are fixedly connected to both the upper and lower sides of the special-shaped wheel, and the axes of the special-shaped wheel and the ratchets are the same. The drainage tube penetrates from one side of the support rod to the other side, the shaft rod penetrates from one side of the protective cover to the other side of the inner wall of the protective cover, a plurality of flow control holes are formed in the outer surface of the flow control block, the ratchet and the clamping plate are engaged with each other, a concave groove is formed in the lower surface of the upper ratchet, and the concave groove is adapted to the concave groove of the clamping ball. A thin spring is arranged inside the protective cover, and both ends of the thin spring are fixedly connected to the protective cover and the flow blocking block respectively. Rotate the hand valve connected to the shaft rod to adjust the pressure. When the hand valve rotates clockwise, the ratchet on the upper side of the special-shaped wheel rotates clockwise. At the same time, the ratchet hooks the clamping plate, and the special-shaped wheel connected to the clamping plate through the connecting column rotates clockwise. When the special-shaped wheel rotates clockwise, the flow blocking block in contact with the special-shaped wheel slowly moves backward under the pulling force of the spring, making the flow blocking block move away from the inner wall of the protective cover, so that more flow control holes on the flow control block at the front end of the flow blocking block are exposed, increasing the flow rate. When the special-shaped wheel rotates counterclockwise, the flow blocking block in contact with the special-shaped wheel slowly moves forward under the action of the special-shaped wheel, making the flow blocking block move closer to the inner wall of the protective cover, reducing the exposed flow control holes and decreasing the flow rate. When the appropriate pressure is adjusted, stop rotating the hand valve. At this time, the clamping ball on the telescopic column will fall into the concave groove on the ratchet, stopping the rotation of the ratchet. This process can control the pressure inside the catheter and the liquid flow rate, making it more convenient for medical staff to adjust the drainage rate.

[0008] According to the above technical solution, the barrel-changing mechanism includes a bottom plate fixedly connected to the upper surface of a fixed rod. A placement plate is slidably connected inside the bottom plate. A pressure spring is provided at the front end of the bottom plate. A placement tray is slidably connected inside the placement plate. A drainage bucket is attached to the upper surface of the placement tray. An anti-overflow ring is attached inside the drainage bucket. Two disc-shaped chutes are provided on the upper surface of the placement plate. The placement tray is fixedly connected to the placement plate by a spring. When the external motor is started to move the shaft rod upward, when the shaft rod moves upward, the threaded rod drives the hinged plate to move upward. When the hinged plate moves upward, the slider on the hinged rod moves away from each other on the sliding table, causing the fixed columns connected to the sliding plate to move synchronously. The clamping plate and the clamping block on the fixed column loosen the drainage bucket and the cover plate. Subsequently, the drainage bucket disengages from the cover plate under the action of gravity. Under the elastic force of the pressure spring, the placement plate connected to the pull plate is pushed, causing the spare drainage bucket to move below the cover plate. During the movement of the original drainage bucket, the anti-overflow ring prevents the liquid in the bucket from overflowing due to shaking. When the patient drains too much liquid and one drainage bucket is not enough to hold the drainage fluid, it is convenient to quickly replace the drainage bucket.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0010] In the present invention, by providing a hinged plate, a hinged rod, a threaded rod, a sliding table, a slider, a sliding plate, a clamping plate, a fixed column, a clamping block, a connecting rod, a support rod, a locking plate, and a locking sleeve, when the clamping plate moves, the locking sleeve on the connecting rod will move synchronously. The movement of the locking sleeve will press the locking plate to completely bind the catheter sleeved on the drainage tube. In this process, the drainage bucket can be firmly fixed on the placement tray, preventing the drainage bucket from shaking and playing a sealing role in the drainage bucket to prevent the internal liquid from accidentally touching and overflowing.

[0011] In the present invention, by providing a shaft rod, a clamping plate, a special-shaped wheel, a ratchet wheel, a connecting column, a flow-blocking block, a flow-control block, and a hand valve, when adjusted to the appropriate pressure, stop turning the hand valve. At this time, the clamping ball on the telescopic column will fall into the concave groove on the ratchet wheel, causing the ratchet wheel to stop rotating. This process can control the pressure in the catheter and at the same time control the liquid flow rate, making it more convenient for medical staff to adjust the drainage rate.

[0012] In the present invention, by providing a bottom plate, a placement plate, a placement tray, a drainage bucket, a pressure spring, an anti-overflow ring, and a pull plate, under the elastic force of the pressure spring, the placement plate connected to the pull plate is pushed, causing the spare drainage bucket to move below the cover plate. During the movement of the original drainage bucket, the anti-overflow ring prevents the liquid in the bucket from overflowing due to shaking. When the patient drains too much liquid and one drainage bucket is not enough to hold the drainage fluid, it is convenient to quickly replace the drainage bucket, preventing the excess liquid from overflowing from the drainage bucket to the bottom surface and avoiding affecting subsequent treatments.

Detailed implementation manners

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-8 , an embodiment of the present invention is a hepatobiliary and pancreatic drainage device convenient for pressure adjustment, including a bottom platform 1, a partition 2 fixedly connected inside the bottom platform 1, a fixing mechanism 3 arranged on the upper surface of the bottom platform 1, fixing rods 8 fixedly connected to both sides of the upper surface of the bottom platform 1, a bucket-changing mechanism 5 arranged on the upper surface of the fixing rods 8, a cover plate 7 attached to the upper surface of the bucket-changing mechanism 5, and a pressure control mechanism 4 arranged on the upper surface of the cover plate 7;

[0026] The fixing mechanism 3 includes a sliding platform 304 and a support rod 311. The sliding platform 304 is fixedly connected to the upper surface of the bottom platform 1, and the support rod 311 is fixedly connected to the upper surface of the cover plate 7. Sliders 305 are slidably connected to the upper surfaces of both ends of the sliding platform 304. A sliding plate 306 is fixedly connected to the upper surface of each slider 305. Fixing columns 308 are fixedly connected to the opposite sides of the two sliding plates 306. A clamping block 309 is fixedly connected to one end of each fixing column 308 away from the sliding plate 306. A clamping plate 307 is fixedly connected to the outer surface of each fixing column 308. A connecting rod 310 is fixedly connected to the upper surface of the right clamping plate 307, and a locking sleeve 313 is fixedly connected to the upper surface of the connecting rod 310. Four locking plates 312 are fixedly connected to the right side of the support rod 311. Hinge rods 302 are arranged on the front and rear sides of the sliding platform 304. A threaded rod 303 is arranged through the middle of the partition 2. One end of the threaded rod 303 is threadedly connected to a hinge plate 301, and the other end of the threaded rod 303 is fixedly connected to the output end of the motor. Both ends of each hinge rod 302 are respectively hinged to the slider 305 and the hinge plate 301. The locking sleeve 313 is sleeved with the locking plate 312. A chute for the movement of the hinge rod 302 is opened on the upper surface of the bottom platform 1. The four locking plates 312 are arranged in a circular pattern. The hinge rod 302 is rotatably connected to the sliding platform 304. When the hinge plate 301 moves downward, it will drive the sliders 305 on the hinge rod 302 to approach each other on the sliding platform 304, so that the fixing columns 308 connected to the sliding plates 306 move synchronously. The clamping plates 307 on the fixing columns 308 move towards the cover plate 7, and the clamping blocks 309 on the sides of the clamping plates 307 approach the edge of the cover plate 7, and then the drainage bucket 504 and the cover plate 7 are firmly fixed. When the clamping plate 307 moves, it will drive the locking sleeve 313 on the connecting rod 310 to move synchronously. The movement of the locking sleeve 313 will press the locking plate 312 to completely bind the catheter sleeved on the drainage tube 409. In this process, the drainage bucket 504 can be firmly fixed on the placement tray 503, so that the drainage bucket 504 does not shake.

[0027] The pressure control mechanism 4 includes a drainage tube 409 which is fixedly connected inside the support rod 311. One end of the drainage tube 409 away from the support rod 311 is fixedly connected with a protective cover 410. A shaft rod 401 is rotatably connected to the upper surface of the protective cover 410. A hand valve 408 is fixedly connected to the upper surface of the shaft rod 401. A special-shaped wheel 403 is rotatably connected to the outer surface of the shaft rod 401. A telescopic column 411 is slidably connected to the upper surface of the special-shaped wheel 403. A clamping ball 412 is fixedly connected to the upper surface of the telescopic column 411. Connecting columns 405 are respectively fixedly connected to the upper and lower sides of the special-shaped wheel 403. A flow-blocking block 406 is attached to the outer surface of the special-shaped wheel 403. A flow control block 407 is fixedly connected to the front end of the flow-blocking block 406. A clamping plate 402 is rotatably connected to the outer surface of each connecting column 405. Ratchets 404 are fixedly connected to both the upper and lower sides of the special-shaped wheel 403, and the axes of the special-shaped wheel 403 and the ratchets 404 are the same. The drainage tube 409 penetrates from one side of the support rod 311 to the other side. The shaft rod 401 penetrates from one side of the protective cover 410 to the inner wall of the other side of the protective cover 410. A plurality of flow control holes are formed on the outer surface of the flow control block 407. The ratchets 404 and the clamping plates 402 are engaged with each other. A concave groove is formed on the lower surface of the upper ratchet 404, and the concave groove is adapted to the concave groove of the clamping ball 412. A thin spring is arranged inside the protective cover 410, and both ends of the thin spring are fixedly connected to the protective cover 410 and the flow-blocking block 406 respectively. When the special-shaped wheel 403 rotates counterclockwise, the flow-blocking block 406 in contact with the special-shaped wheel 403 will slowly move forward under the action of the special-shaped wheel 403, making the flow-blocking block 406 approach the inner wall of the protective cover 410, reducing the exposed flow control holes and making the flow rate smaller. When the appropriate pressure is adjusted, stop rotating the hand valve 408. At this time, the clamping ball 412 on the telescopic column 411 will fall into the concave groove on the ratchet 404, stopping the rotation of the ratchet 404. This process can control the pressure in the catheter and the liquid flow rate, making it more convenient for medical staff to regulate the drainage rate.

[0028] The barrel-changing mechanism 5 includes a bottom plate 501 fixedly connected to the upper surface of a fixed rod 8. A placement plate 502 is slidably connected inside the bottom plate 501. A pressure spring 505 is provided at the front end of the bottom plate 501. A placement tray 503 is slidably connected inside the placement plate 502. A drainage barrel 504 is attached to the upper surface of the placement tray 503. An anti-overflow ring 506 is attached inside the drainage barrel 504. Two disc-shaped chutes are formed on the upper surface of the placement plate 502. The placement tray 503 is fixedly connected to the placement plate 502 by springs. When the hinge plate 301 moves upward, it will drive the sliders 305 on the hinge rod 302 to move away from each other on the sliding table 304, causing the fixed columns 308 connected to the sliding plate 306 to move synchronously. The clamping plates 307 and the locking blocks 309 on the fixed columns 308 release the drainage barrel 504 and the cover plate 7. Subsequently, the drainage barrel 504 separates from the cover plate 7 under the action of gravity. Under the elastic force of the pressure spring 505, the placement plate 502 connected to the pull plate 507 is pushed, causing the spare drainage barrel 504 to move below the cover plate 7. During the movement of the original drainage barrel 504, the anti-overflow ring 506 prevents the liquid in the barrel from overflowing due to shaking. When the patient drains too much liquid and one drainage barrel 504 is not enough to hold the drainage fluid, it is convenient to quickly replace the drainage barrel 504.

[0029] Working principle: First, put the catheter over the drainage tube 409, then place the drainage barrel 504 on the placement tray 503, and then push the pull plate 507 to make the placement plate 502 slide inside the bottom plate 501, moving the drainage barrel 504 on the placement tray 503 below the cover plate 7;

[0030] Start the external motor to make the threaded rod 303 drive the hinge plate 301 to move downward. When the hinge plate 301 moves downward, it will drive the sliders 305 on the hinge rod 302 to move closer to each other on the sliding table 304, causing the fixed columns 308 connected to the sliding plate 306 to move synchronously. The clamping plates 307 on the fixed columns 308 move towards the cover plate 7, and the locking blocks 309 on the sides of the clamping plates 307 approach the edge of the cover plate 7, and then firmly fix the drainage barrel 504 and the cover plate 7. When the clamping plates 307 move, they will drive the locking sleeves 313 on the connecting rod 310 to move synchronously. The movement of the locking sleeves 313 will press the locking plate 312 to completely bind the catheter sleeved on the drainage tube 409. In this process, the drainage barrel 504 can be firmly fixed on the placement tray 503 to prevent the drainage barrel 504 from shaking;

[0031] Insert one end of the catheter into the patient's body, then turn on the negative pressure pump, and rotate the hand valve 408 connected to the shaft rod 401 to adjust the pressure. When the hand valve 408 rotates clockwise, the ratchet 404 on the upper side of the special-shaped wheel 403 rotates clockwise. At the same time, the ratchet 404 hooks the clamping plate 402, and the special-shaped wheel 403 connected to the clamping plate 402 through the connecting column 405 rotates clockwise. When the special-shaped wheel 403 rotates clockwise, the flow-blocking block 406 in contact with the special-shaped wheel 403 slowly moves backward under the pulling force of the thin spring, making the flow-blocking block 406 move away from the inner wall of the protective cover 410, so that more flow control holes on the flow control block 407 at the front end of the flow-blocking block 406 are exposed, increasing the flow rate. When the special-shaped wheel 403 rotates counterclockwise, the flow-blocking block 406 in contact with the special-shaped wheel 403 slowly moves forward under the action of the special-shaped wheel 403, making the flow-blocking block 406 approach the inner wall of the protective cover 410, reducing the exposed flow control holes and decreasing the flow rate. When the appropriate pressure is adjusted, stop rotating the hand valve 408. At this time, the clamping ball 412 on the telescopic column 411 will fall into the concave groove on the ratchet 404, stopping the rotation of the ratchet 404. This process can control the pressure inside the catheter and the liquid flow rate, making it more convenient for medical staff to adjust the drainage rate;

[0032] When it is necessary to replace the drainage bucket 504, start the external motor to move the shaft rod 401 upward. When the shaft rod 401 moves upward, the threaded rod 303 drives the hinged plate 301 to move upward. When the hinged plate 301 moves upward, the slider 305 on the hinged rod 302 moves away from each other on the sliding table 304, making the fixed column 308 connected to the sliding plate 306 move synchronously. The clamping plate 307 and the clamping block 309 on the fixed column 308 release the drainage bucket 504 and the cover plate 7. Then, the drainage bucket 504 separates from the cover plate 7 under the action of gravity. Under the elastic force of the pressure spring 505, the placement plate 502 connected to the pull plate 507 is pushed, making the spare drainage bucket 504 move below the cover plate 7. During the movement of the original drainage bucket 504, the anti-overflow ring 506 prevents the liquid in the bucket from overflowing due to shaking. When the patient drains too much liquid and one drainage bucket 504 is not enough to hold the drainage fluid, it is convenient to quickly replace the drainage bucket 504.
