Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a clog-preventing clinical nursing drainage device. Background Technology

[0002] Medical drainage tubes are widely used in various clinical settings, including the pleural cavity, abdominal cavity, biliary tract, urinary system, and surgical wounds. Their core function is to guide accumulated bodily fluids such as blood, pus, exudate, and urine, as well as gases produced under certain pathological conditions, out of the body. This device effectively prevents fluid and gas accumulation from compressing surrounding tissues and organs, reduces the risk of infection caused by bacterial growth, and ensures wound healing and disease monitoring. For example, after urinary system surgery, drainage via catheter can prevent bladder overdistension; in cancer patients, drainage tubes can relieve organ compression symptoms by draining pleural and peritoneal effusions. They are typically made of silicone rubber or polyurethane and rely on gravity, siphon, or negative pressure suction to achieve drainage, making them an indispensable basic instrument in postoperative care and disease treatment.

[0003] Blockage of drainage tubes can directly affect the treatment effect and even cause serious complications. Currently, there are significant deficiencies in the clinical treatment methods and anti-blockage techniques for blockage. In routine treatment, medical staff often use methods such as flushing with saline or manually adjusting the position of the tube. However, flushing may cause fluid backflow due to improper pressure, resulting in secondary damage.

[0004] Regarding anti-clogging technology, existing techniques have attempted improvements, such as manually cleaning the lumen with a cleaning rod and setting up one-way flow components to improve sealing. However, manual cleaning is complex, has limited effectiveness against viscous blockages, and some anti-clogging structures suffer from weak connections and insufficient sealing, potentially leading to negative pressure failure and consequently affecting drainage efficiency. Therefore, this paper proposes an anti-clogging clinical nursing drainage device to address the aforementioned problems. Summary of the Invention

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-10The present invention provides a technical solution: a clinical nursing drainage device for preventing blockage, including a drainage needle 1, a clamping part 2 on the drainage needle 1, a drainage part 3 installed on the drainage needle 1, a compensation part 4 installed on the drainage part 3, an anti-blockage part 5 connected to the compensation part 4, a diversion part 6 and a limiting sleeve 7 installed on the anti-blockage part 5, the drainage part 3 including a first connecting tube 31, a second connecting tube 32, a third connecting tube 33 and a drainage hole 34, the compensation part 4 including an end 41 connected to the end of the third connecting tube 33, the anti-blockage part 5 including a sleeve 51 sleeved on the third connecting tube 33, and the diversion part 6 including a drain tube 63 connected to the sleeve 51.

[0038] In this embodiment, the clamping part 2 achieves the dual functions of pipeline fixation and blockage detection. It includes a mounting arm 21, with a detection hole 22 on the inner wall of the mounting arm 21. A clamping block 23 is slidably connected in the detection hole 22. A spring 24 is elastically connected between the clamping block 23 and the inner wall of the detection hole 22. A distance sensor 25 is installed on the inner wall of the detection hole 22. The mounting arm 21 and the clamping block 23 elastically clamp the connecting pipe 33 through the spring 24 to ensure pipeline stability and adaptability to different diameters. The distance sensor 25 monitors the change in the distance between the clamping blocks 23 to identify pipeline blockage and the degree of blockage in real time, providing signal support for subsequent processing.

[0039] Furthermore, the drainage section 3 constructs a main channel for fluid flow and reserves a diversion interface. One end of the connecting tube 1 31 is fixedly connected to the drainage needle 1 and connected in a manner. One end of the connecting tube 2 32 is inserted into the other end of the connecting tube 1 31, and the other end of the connecting tube 2 32 is inserted into the end of the connecting tube 3 33 away from the end 41. The drainage holes 34 are arranged in a circular array around the connecting tube 3 33. The connecting tube 3 33 is clamped between the clamps 23 on the mounting arm 21. Through the combination of connecting tube 1 31, connecting tube 2 32, and connecting tube 3 33, basic drainage of fluid from the drainage needle 1 to the end 41 is achieved. The drainage holes 34 on the connecting tube 3 33 provide a channel for diversion when blocked, adapting to the fluid export needs of different blockage scenarios.

[0040] It is worth noting that the compensation section 4 provides elastic buffering and pressure compensation. The end 41 is surrounded by a circular array of sliding rods 42, and each sliding rod 42 is fitted with a spring 43. One end of the sleeve 51 is surrounded by a groove 52 corresponding to the sliding rod 42. The sliding rod 42 is slidably connected to the inner wall of the corresponding groove 52. The sleeve 51 and the end 41 are elastically connected by the spring 43. The end 41 is slidably engaged with the sleeve 51 through the sliding rod 42. When the waste liquid bag 62 expands, the spring 43 is compressed and stores force, and then pushes the sleeve 51 with the reverse elastic force to provide pulse pressure for the impact of the blockage, while ensuring the stability of the sliding stroke of the sleeve 51.

[0041] It is worth noting that the anti-blocking unit 5 triggers diversion and active anti-blocking. The outer wall of the sleeve 51 is surrounded by a circular array of grooves 53. Each groove 53 has a baffle 54 fixedly connected to its inner wall. Each groove 53 has an inlet hole 55 and an outlet hole 56. Each groove 53 has a sliding arm 57 slidably connected to its inner wall. Each sliding arm 57 is elastically connected to the inner wall of its groove 53 by a tension spring 58. Each drain pipe 63 is connected to the inner wall of the outlet hole 56. The inlet hole 55 and the drain hole 34 are connected and correspond one-to-one. The inlet hole 55, outlet hole 56 and groove 53 on the sleeve 51 form a diversion channel. The sliding arm 57 opens the outlet hole 56 under the action of body fluid pressure to achieve body fluid diversion when blocked. The tension spring 58 cooperates with the baffle 54 to ensure that the sliding arm 57 seals the outlet hole 56 under normal conditions to avoid leakage during normal drainage.

[0042] Furthermore, the diversion section 6 temporarily stores the diverted fluid and assists in unblocking. A collar 61 is fixedly fitted on the connecting pipe 33, and a waste fluid bag 62 is adhered to the collar 61. The waste fluid bag 62 is fixedly connected to and communicates with the drain pipe 63. A limiting sleeve 7 is fixedly fitted on the outer wall of the sleeve 51. The inner wall of the limiting sleeve 7 does not contact the sliding arm 57. The limiting sleeve 7 ensures the stability of the diversion. One end of the sliding arm 57 has a notch structure and abuts against the baffle 54 through the notch. The notch end face of the sliding arm 57 blocks the corresponding outlet hole 56. The drain pipe 63 guides the diverted fluid into the waste fluid bag 62 to prevent backflow of accumulated fluid and infection. The waste fluid bag 62 expands and drives the sleeve 51 to slide, which, together with the spring 43 of the compensation section 4, forms a reverse pressure to help unblock the blockage and at the same time allows time for medical staff to handle the situation.

[0043] Working principle: The drainage needle 1 is precisely inserted into the target part of the human body, such as the chest cavity or abdominal cavity. With the help of gravity or external negative pressure, the body fluid is guided out. The core flow path is from the drainage needle 1 to the connecting tube 1 31 to the connecting tube 2 32 to the connecting tube 33 to the end 41, and finally the body fluid is discharged.

[0044] The mounting arm 21 of the clamping part 2 is fixed to the medical equipment or bedside bracket. Through the elastic force of the spring 24, the clamping block 23 clamps the connecting tube 33 from both sides, which not only ensures the stability of the pipeline without displacement, but also adapts to drainage tubes of different diameters.

[0045] The distance sensor 25 inside the detection hole 22 continuously monitors the distance between the clamps 23 on both sides. During normal drainage, the inner diameter of the tube is stable and the distance between the clamps 23 remains constant. When blood clots, tissue fragments, or other blockages occur in the tube, the obstruction of fluid flow will cause the tube to expand locally, pushing the clamps 23 to slide outward from the detection hole 22, and the distance will change.

[0046] The distance sensor 25 determines the location and severity of the blockage by the change in the distance. A slight change in the distance indicates a partial blockage in the third connecting tube 33, while a large change or a constant distance without fluid outflow indicates a severe blockage in the first connecting tube 31 or the second connecting tube 32.

[0047] Connecting pipe 1 31 and connecting pipe 2 32, and connecting pipe 2 32 and connecting pipe 3 33, all adopt a plug-in design. When the sensor detects a blockage in the front section, the corresponding connecting section can be directly disassembled. For example, disassembling connecting pipe 2 32 can resolve the blockage in connecting pipe 1 31, and disassembling connecting pipe 3 33 can resolve the blockage in connecting pipe 2 32. There is no need to disassemble the entire equipment, which reduces the complexity of operation.

[0048] When the connecting tube 33 is blocked, the body fluid cannot be discharged normally through the end 41. It will accumulate in the tube and form pressure, pushing the body fluid to overflow from the liquid inlet hole 34 on the side wall of the connecting tube 33. It will then flow into the groove 53 of the sleeve 51 through the corresponding connecting structure from the liquid inlet hole 34 to the liquid inlet hole 55.

[0049] As bodily fluids continue to accumulate in the chute 53, the pressure gradually increases, overcoming the tension of the tension spring 58 and pushing the sliding arm 57 outward along the chute 53. This causes the notch end face of the sliding arm 57 to disengage from the liquid outlet 56, opening the liquid outlet 56. The bodily fluids then flow through the drain pipe 63 into the waste liquid bag 62 for temporary storage, preventing the accumulated fluids from flowing back into the human body and causing infection.

[0050] After accumulating body fluid, the waste liquid bag 62 gradually expands. Through the collar 61, it drives the sleeve 51 to slide along the connecting pipe 33 towards the end 41, squeezing the spring 43 sleeved on the slide rod 42. After being compressed, the spring 43 generates a reverse elastic force, pushing the sleeve 51 to slide in the opposite direction. The pressure is transmitted to the drain pipe 63 through the waste liquid bag 62, causing the temporarily stored body fluid to flow back to the inlet hole 55. The pulse pressure impacts the blockage in the connecting pipe 33, achieving active unblocking.

[0051] When the sliding arm 57 slides outward to a certain distance, its outer wall contacts the inner wall of the limiting sleeve 7. The limiting sleeve 7 restricts the sliding arm 57 from continuing to move, ensuring that the liquid outlet 56 remains in the maximum opening state and ensuring diversion efficiency.

[0052] The waste fluid bag 62 is designed to meet short-term fluid storage needs, providing ample time for medical staff to handle blockages such as flushing and clearing obstructions, thus avoiding complications caused by drainage interruption due to blockage.

[0053] The sleeve 51 is slidably connected to the slide rod 42 of the end 41 through the rod groove 52. The second spring 43 is always in a slightly tense state, which not only ensures the relative fixation of the sleeve 51 and the connecting tube 33, but also provides a smooth sliding stroke when the waste liquid bag 62 expands, ensuring stable pressure transmission of elastic back thrust.
