Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surgical drainage devices, and particularly relates to a portable surgical drainage device. BACKGROUND

[0002] The water seal bottle is a basic device for closed pleural cavity drainage, which is an important measure for treating pneumothorax, hemopneumothorax and pyothorax, and is a basic treatment measure in thoracic surgery. The closed pleural cavity drainage is designed according to the physiological characteristics of the human pleural cavity, and relies on the liquid in the water seal bottle to isolate the pleural cavity from the outside world, to form a closed device and maintain the negative pressure of the pleural cavity. When the pleural cavity is high pressure due to fluid or gas accumulation, the liquid or gas in the pleural cavity can be discharged into the drainage bottle.

[0003] For the current drainage device, such as the chest closed drainage device and the manufacturing method thereof disclosed in Chinese patent publication No. CN110227186A, water needs to be added to the water seal bottle during use to achieve the effect of gas sealing. However, in the case of continuous use of the water seal bottle, the liquid inside the water seal bottle will gradually evaporate, resulting in insufficient water level and affecting the gas sealing effect, which can cause damage to the chest cavity of the patient. Accordingly, the present application proposes a portable surgical drainage device. SUMMARY

[0013] Preferably, the inner wall of the anti-overflow cavity is fixedly provided with a first fixed valve, the first fixed valve is rotatably connected with a sliding sheet, the top of the sliding sheet is fixedly provided with a support rod, the end of the support rod is fixedly provided with a gas chamber box, the inside of the first fixed valve is provided with a through-flow hole, the bottom of the sliding sheet is fixedly provided with a stopper in the through-flow hole, the outer wall of the anti-overflow cavity is fixedly provided with a through-flow pipe in communication with the through-flow hole, and the water inlet port of the through-flow pipe is in communication with the effusion cavity.

[0014] Preferably, one side of the inside of the connecting bottle is provided with a water seal cavity, the other side of the inside of the connecting bottle is provided with a pressure regulating cavity, the water seal cavity and the pressure regulating cavity are in communication with each other through a second connecting pipe, the second connecting pipe is provided with a one-way valve, the inside of the pressure regulating cavity is fixedly provided with a long pipe extending to the deep part of the bottom of the pressure regulating cavity, and one side of the top of the connecting bottle is provided with a connecting tube in communication with the inside of the pressure regulating cavity.

[0015] Preferably, the inner wall of the water seal cavity is fixedly provided with a second fixed valve, one side of the second fixed valve is fixedly provided with a fixed ring, the inside of the second fixed valve is rotatably connected with a rotating pipe, one side of the outer wall of the rotating pipe is connected with the fixed ring through a torsional spring, one side of the outer wall of the rotating pipe in the inside of the second fixed valve is provided with a through hole, and the bottom of the second fixed valve is provided with a water outlet port matched with the through hole.

[0016] Preferably, one side of the fixed ring is rotatably connected with a rotating arm, the rotating arm is fixedly connected with the rotating pipe, and the rotating arm is fixedly connected with a floating ball through a hanging rope.

[0017] Preferably, one end of the first connecting pipe is in communication with the effusion cavity, the other end of the first connecting pipe is in communication with the water seal cavity, and the end of the first connecting pipe close to the water seal cavity extends to the deep part of the bottom of the water seal cavity.

[0018] Preferably, the position of the through hole of the rotating pipe and the position of the water outlet port are vertically staggered when the inside of the water seal cavity is full of liquid.

[0020] The present application has the following beneficial effects:

[0021] 1. The second fixed valve and the floating ball realize "liquid level monitoring-automatic supply". The floating ball drives the rotating arm and the rotating pipe to adjust the angle as the water seal cavity liquid level drops, so that the through hole is aligned with the water outlet, and the liquid in the water tank automatically flows into the water seal cavity. After the liquid level rises, the torsional spring drives the rotating pipe to reset and stop the supply. The whole process does not need manual intervention; the water tank stores sufficient water seal liquid at one time and is in sealed connection with the second fixed valve, which avoids the trouble of frequent addition of liquid during surgery, guarantees the cleanliness of the liquid, prevents air from flowing back to the chest cavity due to water seal failure, and improves the safety of drainage.

[0022] 2. The anti-overflow assembly relies on the first fixed valve to build a "buoyancy sensing-mechanical linkage" mechanism. The air chamber box drives the sliding sheet to rotate as the hydrops liquid level rises, so that the stop block automatically opens the through-flow hole when the hydrops exceeds the amount, so that the hydrops that is about to overflow enters the channel of the anti-overflow cavity. The medical staff does not need to be on duty in real time; the through-flow pipe guides a small amount of hydrops under normal conditions to avoid local accumulation of the collection bottle. The drainage port can empty the hydrops in the anti-overflow cavity without disassembling the collection bottle, reducing the operation steps while avoiding damage to the sealed environment and causing infection, effectively solving the problem that the traditional device is easy to cause hydrops overflow due to negligence.

[0023] 3. The collection bottle and the connection bottle are integrated and fixed through the outer sleeve frame, taking into account portability and anti-toppling ability, which can meet the needs of different surgical scenes such as emergency, transportation, and outpatient service; the sealing cover of the collection bottle and the shunt pipe ensure the closed introduction of hydrops and avoid bubble interference, the water seal cavity of the connection bottle blocks air backflow and the pressure regulating cavity balances pressure, combined with the first connecting pipe extending to the bottom of the water seal cavity, which not only ensures that there is no residual drainage of hydrops, but also prevents the sudden drop of chest pressure through the liquid column resistance, while the long pipe and the connection pipe provide visual pressure reference and adjustable drainage pressure for medical staff, adapting to the needs of different patients.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Example 1:

[0037] Reference Figures 1-6 A portable surgical drainage device includes a drainage component, an anti-overflow component, and a self-repairing component;

[0038] The drainage assembly is used to drain effusion from the patient's pleural cavity. The drainage assembly includes an outer frame 1 and a collection bottle 2 fixedly connected to one side inside the outer frame 1.

[0039] A receiving bottle 3 is fixedly installed on the other side inside the outer frame 1;

[0040] The overflow prevention assembly is used to prevent the liquid inside the collection bottle 2 from overflowing. The overflow prevention assembly includes a first fixed valve 11 fixedly installed inside the collection bottle 2.

[0041] The self-replenishing component is used to automatically replenish the liquid in the water-sealed bottle. The self-replenishing component includes a second fixed valve 24 fixedly installed inside the receiving bottle 3.

[0042] The collection bottle 2 has a liquid accumulation chamber 7 inside, and an overflow prevention chamber 8 is provided inside the collection bottle 2 and located in the center of the liquid accumulation chamber 7. The bottom of the collection bottle 2 is provided with a drain outlet 9 that communicates with the overflow prevention chamber 8. The top of the liquid accumulation chamber 7 is fixedly provided with a diversion pipe 10 that communicates with the drainage pipe 5.

[0043] A first fixed valve 11 is fixedly installed on the inner wall of the overflow chamber 8. A sliding plate 12 is rotatably connected inside the first fixed valve 11. A support rod 13 is fixedly installed on the top of the sliding plate 12. An air chamber box 14 is fixedly installed at the end of the support rod 13. A flow passage hole 15 is opened inside the first fixed valve 11. A stop block 16 located inside the flow passage hole 15 is fixedly installed at the bottom of the sliding plate 12. A flow passage pipe 17 connected to the flow passage hole 15 is fixedly installed on the outer wall of the overflow chamber 8. The water inlet of the flow passage pipe 17 is connected to the liquid accumulation chamber 7.

[0044] The collection bottle 2 is divided into a fluid accumulation chamber 7, which occupies 3 / 4 of the collection bottle's volume, and an overflow prevention chamber 8, which occupies 1 / 4 of the volume, for overflow prevention and buffering. A diversion tube 10 is welded to the inner wall of the top of the fluid accumulation chamber 7. The input end of the diversion tube 10 is connected to the lower end of the drainage tube 5, and the output end has 3 evenly distributed diversion holes. When pleural effusion flows in through the drainage tube 5, the diversion tube 10 can guide the effusion evenly to the inner wall of the fluid accumulation chamber 7, avoiding the effusion from directly impacting the bottom of the chamber and generating air bubbles, which would interfere with the accuracy of pressure monitoring.

[0045] In this embodiment, when the liquid level in the accumulating cavity 7 does not reach the height of the flow tube 17, the buoyancy of the air chamber 14 is small, the slide plate 12 remains horizontal, and the block 16 blocks the flow hole 15. The liquid in the accumulating cavity 7 cannot flow into the overflow chamber 8 through the flow tube 17 and the flow hole 15. When the liquid in the accumulating cavity 7 continues to increase and the liquid level rises to the height of the flow tube 17, the air chamber 14 floats upward under the action of buoyancy. Through the support rod 13, it drives the slide plate 12 to rotate clockwise around the first fixed valve 11 shaft. The block 16 at the bottom of the slide plate 12 moves synchronously until the flow hole 15 is fully opened. At this time, the liquid can enter the overflow chamber 8, realizing "automatic drainage before excessive liquid accumulation", without the need for medical staff to check the liquid level in real time.

[0046] During surgical breaks or after spill prevention, open the drain port 9 at the bottom of collection bottle 2, which connects to spill prevention chamber 8. A valve is installed at the drain port to empty the accumulated fluid in spill prevention chamber. This eliminates the need to disassemble the collection bottle, reducing operational steps and avoiding disruption of the sealed environment that could lead to infection.

[0047] Example 2:

[0048] Reference Figures 9-10 Compared to Embodiment 1, in this embodiment, the top of the collection bottle 2 is provided with a sealing cap 4, and a drainage tube 5 is provided on the sealing cap 4. The collection bottle 2 and the receiving bottle 3 are connected to each other through a first connecting tube 6.

[0049] A water seal chamber 18 is provided on one side of the inside of the receiving bottle 3, and a pressure regulating chamber 19 is provided on the other side of the inside of the receiving bottle 3. The water seal chamber 18 and the pressure regulating chamber 19 are connected to each other through a second connecting pipe 20. A one-way valve 21 is provided on the second connecting pipe 20. A long pipe 22 extending to the bottom of the pressure regulating chamber 19 is fixedly provided inside the pressure regulating chamber 19. A receiving pipe 23 communicating with the inside of the pressure regulating chamber 19 is provided on one side of the top of the receiving bottle 3.

[0050] A second fixed valve 24 is fixedly installed on the inner wall of the water seal cavity 18. A fixed ring 25 is fixedly installed on one side of the second fixed valve 24. A rotating pipe 26 is rotatably connected inside the second fixed valve 24. One side of the outer wall of the rotating pipe 26 is connected to the fixed ring 25 by a torsion spring 27. A through hole 28 is opened on the outer wall of the rotating pipe 26 inside the second fixed valve 24. A water outlet 29 matching the through hole 28 is opened at the bottom of the second fixed valve 24.

[0051] A rotating arm 30 is rotatably connected to one side of the fixed ring 25. The rotating arm 30 is fixedly connected to the rotating tube 26. A floating ball 31 is fixedly connected to the rotating arm 30 by a hanging rope.

[0052] One end of the first connecting pipe 6 is connected to the liquid accumulation chamber 7, and the other end of the first connecting pipe 6 is connected to the water seal chamber 18. The end of the first connecting pipe 6 near the water seal chamber 18 extends to the bottom of the water seal chamber 18. When there is sufficient liquid inside the water seal chamber 18, the position of the through hole 28 on the rotating pipe 26 is perpendicularly staggered with the position of the outlet 29.

[0053] A water tank 32 is fixedly installed on one side of the outer wall of the receiving bottle 3, and the water outlet of the water tank 32 is connected to the water inlet of the second fixed valve 24.

[0054] The system includes a water seal chamber 18 and a pressure regulating chamber 19, separated by a partition inside the receiving bottle 3, to store the water seal liquid and balance the pressure. An interface is provided on the partition between the water seal chamber 18 and the pressure regulating chamber 19 to install a second connecting pipe 20. A one-way valve 21 is welded onto the second connecting pipe 20, with the flow direction of the one-way valve 21 from the water seal chamber 18 to the pressure regulating chamber 19, preventing backflow of liquid in the pressure regulating chamber 19. A long pipe 22 is vertically welded inside the pressure regulating chamber 19, with its lower end extending to the bottom of the pressure regulating chamber 19. Medical personnel can visually judge the pressure status of the pressure regulating chamber 19 by observing the liquid level in the long pipe 22, thus achieving visual pressure monitoring.

[0055] Furthermore, the first connecting tube 6 is made of transparent silicone to facilitate observation of the flow of the accumulating fluid. One end is connected to the top of the accumulating fluid chamber 7 of the collection bottle 2 through an interface, and the other end passes through the top of the receiving bottle 3 and extends to the bottom of the water seal chamber 18. This design ensures that the gas in the accumulating fluid chamber 7 can completely enter the water seal chamber 18, and also uses the "liquid column resistance" of the liquid in the water seal chamber to slow down the gas flow rate. The resistance formed by the liquid depth can prevent the drainage from being too fast and causing a sudden drop in thoracic pressure.

[0056] In this embodiment, physiological saline solution of a preset height is injected into the water seal cavity 18. At this time, the floating ball 31 is in a high position due to buoyancy. The rotating arm 30 drives the rotating tube 26 to maintain the initial angle. The through hole 28 of the rotating tube 26 is perpendicular to the outlet 29 of the second fixed valve 24, so the liquid cannot pass through and the water tank 32 is not replenished.

[0057] As the drainage process progresses, the liquid in the water seal chamber 18 decreases due to evaporation or discharge with the accumulated liquid. The drop in liquid level causes the floating ball 31 to sink, and the rotating arm 30 rotates around the fixed ring 25, thereby driving the rotating tube 26 to rotate synchronously. The torsion spring 27 is twisted and stores energy. When the liquid level drops to the preset minimum height, the through hole 28 of the rotating tube 26 is completely aligned with the outlet 29 of the second fixed valve 24. The saline solution in the water tank 32 flows into the water seal chamber 18 through the second fixed valve 24, through hole 28, and outlet 29, achieving automatic replenishment without the need for manual liquid addition.

[0058] As the liquid continues to be replenished, the liquid level in the water seal chamber 18 rises, the floating ball 31 rises, the rotating arm 30 drives the rotating tube 26 to reset, the torsion spring 27 returns to its natural state, the through hole 28 and the outlet 29 cross again, and the replenishment stops. The entire process achieves a closed loop of "liquid level monitoring - automatic replenishment - reset and cut off flow" through a mechanical structure, without the need for electric drive. Moreover, the airtight connection between the water tank 32 and the second fixed valve 24 can prevent external contamination of the liquid, ensure the cleanliness of the water seal liquid, and avoid air backflow due to water seal failure.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
