Description

Technical Field

[0001] This invention relates to the field of abdominal drainage technology, and in particular to a device for detecting abdominal drainage fluid in hepatobiliary and pancreatic surgery. Background Technology

[0002] Abdominal drainage is a common procedure in hepatobiliary and pancreatic surgery and postoperative treatment. Drainage removes fluid from the abdominal cavity, preventing complications such as infection and abscesses caused by fluid accumulation, and promoting wound healing and recovery. However, existing abdominal drainage devices have some problems and shortcomings in their use.

[0003] On the one hand, the flow status of drainage fluid is difficult to monitor and accurately determine in real time. The properties of drainage fluid can reflect the pathological condition in the abdominal cavity, but existing devices can usually only make a rough judgment by observing the final state of the drainage fluid collected in the drainage bag. They cannot detect abnormalities in time during the drainage process. For example, if the drainage fluid suddenly becomes turbid or viscous, it may indicate new bleeding, infection or tissue necrosis in the abdominal cavity, thus delaying the early detection and treatment of the disease.

[0004] On the other hand, drainage tubes are prone to blockage. The drainage fluid may contain various solid components, which can easily accumulate inside the tube, clogging the lumen and leading to poor drainage or even drainage failure. Once the drainage tube is blocked, it not only affects the drainage effect but may also increase intra-abdominal pressure, causing discomfort such as abdominal distension and pain, and in severe cases, even endangering the patient's life. Currently, methods for resolving drainage tube blockage are often cumbersome, requiring disassembly of the drainage tube for flushing or replacement. This not only increases the workload of medical staff but may also increase the risk of infection, causing additional pain and inconvenience to the patient.

[0005] Furthermore, existing drainage devices also have some shortcomings in the collection and storage of drainage fluid. For example, when the drainage fluid flows directly into the drainage bag, the large internal space of the bag easily leads to a significant difference in liquid level, resulting in unstable flow and the formation of air bubbles, which affects the observation and judgment of the drainage effect. Moreover, when further testing or analysis of the drainage fluid is required, sampling from the drainage bag is not convenient or hygienic. Summary of the Invention

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example 1

[0029] Reference Figures 1-7 This is the first embodiment of the present invention. This embodiment provides a device for detecting abdominal drainage fluid in hepatobiliary and pancreatic surgery, which includes a pressure regulating structure 100, a flexible tube 101, and a buffer bladder 102 disposed in the middle of the flexible tube 101. The collection device 200 includes a storage box 201, which has a through hole 201a, a one-way valve detachably mounted on the inner wall of the through hole 201a, and an isolation plate 202 located inside the storage box 201.

[0030] The buffer bladder 102 is made of a deformable material, and the upper and lower ends of the buffer bladder 102 are connected to flexible tubes 101. The lower flexible tube 101 is connected to the storage box 201, which is made of glass. At the same time, an isolation plate 202 is set inside to isolate the internal space. However, at the bottom of the storage box 201, there is a channel in the isolation plate 202 that allows the internal parts of the storage box 201 to communicate with each other. The advantage of this design is that when the drainage fluid enters the storage box 201 through the flexible tube 101, the inside of the storage box 201 forms a structure similar to the principle of a "U" shaped tube.

[0031] Preferably, there are two isolation plates 202, and a first chamber 203 and a second chamber 204 are formed between the two isolation plates 202. The first chamber 203 and the second chamber 204 are connected by a flow channel 202a. The through hole 201a connects the second chamber 204 to the outside of the storage box 201.

[0032] Two isolation plates 202 are provided, forming a first chamber 203 between the two isolation plates 202. A second chamber 204 is formed between the isolation plates 202 and the inner walls of the left and right sides of the storage box 201. The first chamber 203 and the second chamber 204 are connected by a flow channel 202a, that is, the isolation plates 202 are not in contact with the bottom of the storage box 201, thus forming the flow channel 202a. A flexible tube 101 is connected to the inside of the first chamber 203; the drainage fluid flows into the first chamber 203 through the flexible tube 101, and then flows evenly to the second chambers 204 on both sides through the flow channel 202a.

[0033] The storage box 201 has a through hole 201a above the second chamber 204. This design prevents air from flowing out due to the internal seal, which could create a pressure difference and block the drainage fluid. A rubber one-way valve is installed inside the through hole 201a, allowing air to flow only from the inside of the storage box 201 to the outside, not inwards. The deformable nature of rubber allows for easy installation and removal of the one-way valve. The through hole 201a can then be covered with a sterile cotton pad. Furthermore, if the hose 101 becomes clogged, it can be disassembled, and water can be flushed through the through hole 201a. The water enters from the two second chambers 204, flows into the first chamber 203, and then flushes the hose 101, providing a backflushing effect. Compared to existing technologies, this eliminates the need to disassemble the hose and bag for flushing when the hose is clogged.

[0034] At the same time, liver and gallbladder drainage fluid test strips can be inserted through the through-hole 201a to measure the state of the internal drainage fluid. Based on the changes in the test strips, the current state of the drainage fluid can be determined, thereby judging the state of the patient's abdominal cavity during or after surgery.

[0035] When in use, connect the tubing 101 to the corresponding position in the patient's abdominal cavity, and then plug the through hole 201a with the one-way valve. Subsequently, under the influence of gravity, the drainage fluid continuously flows into the storage box 201. If the drainage fluid is turbid or viscous, the buffer bladder 102 can be pressed continuously by hand. The internal gas begins to flow outward along the one-way valve, the air pressure inside the storage box 201 decreases, and the tubing 101 connected to the abdominal cavity begins to aspirate the drainage fluid inside the abdominal cavity, which then enters the storage box 201. By continuously squeezing the buffer bladder 102, the air pressure can be used to create suction inside the tubing at the upper end of the buffer bladder 102, quickly drawing the drainage fluid into the storage box and preventing turbid or viscous fluid from clogging the tubing. Example 2

[0036] Reference Figures 1-7 This is the second embodiment of the present invention, which differs from the first embodiment in that: a rigid shell 103 is connected between the flexible tube 101 and the buffer bladder 102, and an installation ring 103a is provided on the end face of the rigid shell 103; The rigid shell 103 has a sliding mounting block 104 inside.

[0037] A rigid shell 103 is provided between the flexible tube 101 and the buffer bladder 102. The rigid shell 103 is made of a non-deformable material, such as plastic or metal. A mounting block 104 is fixed on the upper surface of the rigid shell 103. The mounting block 104 is a frustum-shaped ring. In use, the upper end of the flexible tube 101 can be directly inserted into the outer wall of the mounting ring 103a, and the connection is made by friction.

[0038] Preferably, the inner wall of the mounting ring 103a is provided with a first arc surface 103a-1.

[0039] The inner wall of the mounting ring 103a has a first arc surface 103a-1. The advantage of this design is that the drainage fluid flows along the first arc surface 103a-1 to the storage box 201. There is no situation where there is a break at the connection, which would cause the drainage fluid to accumulate and stay here, eventually leading to a blockage.

[0040] Furthermore, the hard shell 103 has a first rotating disk 105 inside, the surface of the first rotating disk 105 has a first sliding groove 105a, and the outer wall of the mounting block 104 has a first slider 104a that can slide along the inner wall of the first sliding groove 105a.

[0041] The mounting block 104 can slide up and down, and a first slider 104a is fixedly mounted on the lower surface of the mounting block 104. The upper surface of the first rotating disk 105 has a first groove 105a recessed downwards, and the depth of the groove 105a gradually decreases from one end to the other. This design is so that when the first rotating disk 105 is rotated, the first slider 104a begins to slide along the bottom surface inside the first groove 105a, and at the same time, it begins to continuously push the mounting block 104 upwards, while simultaneously squeezing the hose 101, causing the hose 101 to be compressed.

[0042] Furthermore, to make the connection more convenient, the outer wall of the mounting block 104 is recessed inward to form a second sliding groove 104b. The second sliding groove 104b is provided with a first elastic element 106, and a limiting rod 107 is slidably provided inside the second sliding groove 104b.

[0043] Each mounting block 104 has a second sliding groove 104b near its outer surface. A first elastic element 106 is fixedly mounted to the bottom of the second sliding groove 104b, and a limiting rod 107 is fixedly connected to the other end of the first elastic element 106. The limiting rod 107 can slide along the inside of the second sliding groove 104b. This design allows for a larger space between the mounting block 104 and the outer wall of the mounting ring 103a. When the first rotating disk 105 rotates, the first slider 104a begins to slide along the inner wall of the first sliding groove 105a. Then, the mounting block 104 begins to move upwards. When the second sliding groove 104b slides past the upper surface of the rigid shell 103, the first elastic element 106 pushes the limiting rod 107 outwards, causing it to abut against the surface of the flexible hose 101 on the outer wall of the mounting ring 103a. By increasing the pressure, the connection between the flexible hose and the rigid shell 103 is ensured.

[0044] Furthermore, the outer wall of the first rotating disk 105 is provided with a second elastic element 108, which is fixedly connected to the inner wall of the hard shell 103.

[0045] A second elastic element 108 is connected between the outer wall of the first rotating disk 105 and the hard shell 103, and the second elastic element 108 is a torsion spring. The advantage of this design is that it can maintain the position of the first rotating disk 105 and ensure that the first rotating disk 105 will not detach from the hard shell 103.

[0046] Furthermore, the outer wall of the first rotating disk 105 is provided with a protrusion 105b, which includes a second arc surface 105b-1 and a vertical surface 105b-2. The outer wall of the hard shell 103 is provided with a slide rail 103b, and the slide rail 103b is provided with an abutment rod 103c that can contact the protrusion 105b.

[0047] The rigid shell 103 has a cylindrical slide rail 103b fixedly installed on its outer wall, and there are two slide rails 103b. The slide rails 103b are connected to the interior of the rigid shell 103. At the same time, an abutment rod 103c slides inside the slide rail 103b. Multiple protrusions 105b are arrayed on the outer wall of the first rotating disk 105. Each protrusion 105b includes a second arc surface 105b-1 and a vertical surface 105b-2. When one of the abutment rods 103c is pushed inward, it will slide along the second arc surface 105b-1, and then push the first rotating disk 105 to rotate, thereby pushing the mounting block 104 to move upward, and then connecting the hose 101 to the rigid shell 103.

[0048] Preferably, the inner wall of the slide rail 103b is provided with a fourth slide groove 103b-1; the outer wall of the abutment rod 103c is provided with a limiting platform 103c-1, and a third elastic member 109 is provided between the limiting platform 103c-1 and the inner wall of the fourth slide groove 103b-1.

[0049] The inner wall of the slide rail 103b is recessed outward to form a fourth slide groove 103b-1. At the same time, the outer wall of the abutment rod 103c is provided with a limiting platform 103c-1, and there are two limiting platforms 103c-1. One of them has the same radius as the inner diameter of the slide rail 103b and is sealed. The outer wall of the other limiting platform 103c-1 is connected to the inner wall of the fourth slide groove 103b-1 by a third elastic element 109. The third elastic element 109 is a compression spring. When the abutment rod 103c is pushed inward, the abutment rod 103c is released, and the third elastic element 109 pushes the abutment rod 103c outward. The second elastic element 108 resets the first rotating disk 105.

[0050] In use, the hose 101 is inserted into the outer surface of the mounting ring 103a, and then one of the abutment rods 103c is pushed. The abutment rod 103c then pushes the first rotating disk 105 to rotate. The first rotating disk 105 pushes the mounting block 104 to move upward. Then the limiting rod 107 pops out and abuts against the outer surface of the hose 101, reinforcing the connection between the rigid shell 103 and the hose 101. Example 3

[0051] Reference Figures 1-7 This is the third embodiment of the present invention, which differs from the previous three embodiments in that: the inner wall of the first rotating disk 105 is provided with a stirring rod 103d, and the outer wall of the stirring rod 103d is provided with serrations 103d-1.

[0052] The first rotating disk 105 is an annular structure, and the stirring rod 103d is a cylinder with its axis colinear with the axis of the first rotating disk 105. The stirring rod 103d and the first rotating disk 105 are fixedly connected by a rod, meaning that when the first rotating disk 105 rotates, it can drive the stirring rod 103d to rotate. The outer wall of the stirring rod 103d is provided with serrations 103d-1. The advantage of this design is that when the stirring rod 103d rotates, the serrations 103d-1 will also rotate synchronously, which can stir the turbid and viscous drainage liquid. This can create a vortex inside the upper hose 101 and stir the flowing drainage liquid, which can segment the drainage liquid and allow a small amount of drainage liquid to enter the lower hose for easier flow.

[0053] In summary, during use, the hose is inserted into the outer wall of the mounting ring 103a on the upper surface of the rigid shell 103, and then the abutment rod 103c is pushed. The abutment rod 103c slides along the second arc surface 105b-1, pushing the first rotating disk 105. Then the first slider 104a on the outer wall of the mounting block 104 slides along the inner wall of the first groove 105a, and the mounting block 104 slides upward to clamp the hose 101.

[0054] Lower hose blockage: When the lower hose 101 is blocked, the abutment rod 103c can be continuously pushed. As the abutment rod 103c slides inside the slide rail 103b, the air inside the slide rail 103b is continuously pushed into the buffer bladder 102, exerting a continuous pushing force on the lower hose 101. Due to the action of the one-way valve, the downward-pushed gas will not flow back upward. At the same time, since there is not much gas inside the slide rail 103b, it will not significantly affect the flow rate of the upper hose. If the lower hose 101 is severely blocked, the buffer bladder 102 can be squeezed, and the air pressure will push downward. At this time, pull one of the abutment rods 103c outward to connect the inside with the outside. The buffer bladder 102 draws in the external gas through the slide rail 103b, and then the abutment rod 103c closes the slide rail 103b again. This operation can be repeated to continuously push the drainage fluid inside the lower hose 101, and then the gas is discharged through the one-way valve. It should be noted that when the drainage fluid is flowing normally, the through hole 201a can be covered with sterile cotton. When it is necessary to clear the blockage, the through hole 201a should be controlled by a one-way valve.

[0055] Upper hose blockage: If the upper hose 101 becomes blocked, the buffer bladder 102 can be squeezed, and at the same time, the abutment rod 103c can be pushed inward. The abutment rod 103c pushes the first rotating disk 105 to rotate, which in turn drives the second elastic element 108 to rotate, generating potential energy. When the abutment rod 103c is released, the third elastic element 109 pushes the abutment rod 103c outward. The second elastic element 108 releases potential energy, the first rotating disk 105 rotates, the stirring rod 103d starts to rotate, and at the same time, the saw teeth 103d-1 starts to rotate. During this process, the buffer bladder 102 begins to recover, creating negative pressure from top to bottom. The upper hose 101 has suction inside, and at the same time, the stirring rod 103d stirs the internal drainage fluid, while the saw teeth 103d-1 cuts the drainage fluid, forming a small amount of drainage fluid, which is convenient for the negative pressure to pull. Simultaneously, one abutment rod 103c can be pushed first, followed by pushing the first rotating disk 105 to rotate along the second arc surface 105b-1. Another abutment rod 103c is then pushed in to abut the second arc surface 105b-1. One abutment rod 103c is then removed, and the other abutment rod 103c is pushed again, thus continuously rotating the first rotating disk 105 and increasing the potential energy of the second elastic element 108. Subsequently, the buffer bladder 102 is squeezed, releasing the two abutment rods 103c. The drainage fluid inside the upper hose 101 tends to move downwards. Combined with the stirring of the stirring rod 103d, the hose 101 can be cleared of blockages without disassembly.
