Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a disposable drainage and aspiration device. Background Technology

[0002] In the medical field, effective cleaning and treatment of fracture wounds and infected wounds play a crucial role in the patient's recovery process. Good wound cleaning can significantly reduce the risk of infection, promote wound healing, and improve the patient's cure rate and recovery quality. With the continuous advancement of medical technology, the requirements for the refinement and efficiency of wound treatment are also increasing. Traditional wound treatment methods are gradually becoming unable to meet the needs of modern medicine, and there is an urgent need for a more advanced, efficient, and safe wound treatment instrument.

[0003] Common traditional irrigation devices mainly rely on simple syringes or irrigation bottles for operation. These devices usually involve manually squeezing the syringe or tilting the irrigation bottle to make the irrigation fluid impact the wound at a low pressure in order to achieve the purpose of cleaning. In some more complex wound treatment scenarios, the irrigation effect is not good. Early drainage devices were mostly single-function devices, focusing only on draining waste fluid and contaminated blood from the wound.

[0004] Early drainage devices had poor drainage effects and lacked good adhesion to the wound. During the drainage process, waste fluid and contaminated blood easily accumulated around the wound and could not be absorbed by the drainage tube in time, affecting the drainage efficiency. Moreover, the single drainage function meant that the wound could not be rinsed simultaneously during the drainage process, resulting in the inability to coordinate wound cleaning and waste fluid drainage, which reduced the treatment effect. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a disposable drainage and aspiration device, which solves the problems of poor drainage effect of the drainage tube in early drainage devices, lack of good adhesion to the wound surface, waste fluid and blood sludge easily accumulating around the wound surface during drainage, which cannot be sucked up by the drainage tube in time, affecting the drainage efficiency. Moreover, the single drainage function means that the wound surface cannot be rinsed simultaneously during the drainage process, resulting in the inability to coordinate wound cleaning and waste fluid drainage, thus reducing the treatment effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a disposable drainage and aspiration device, comprising a main body, a first connection port fixedly connected to one side of the main body, a first drainage tube snapped into the first connection port, a drainage head snapped into one end of the first drainage tube, a plurality of connecting rods fixedly installed inside the drainage head, a limiting head fixedly connected between the connecting rods, a second drainage tube snapped into the limiting head, and a third connection port and a second connection port provided on the other side of the main body for use with the first drainage tube and the second drainage tube, one end of the second drainage tube being connected to the second connection port.

[0007] As a further embodiment of this utility model: the second drainage tube is located inside the first drainage tube, the diameter of the second drainage tube is smaller than that of the first drainage tube, and the limiting head is provided with a groove for use with the second drainage tube.

[0008] As a further embodiment of this utility model: a drainage port is provided on one side of the limiting head for use with the second drainage pipe.

[0009] As a further embodiment of this utility model: the drainage head has a horn-shaped opening and is made of silicone material.

[0010] As a further embodiment of this utility model: the main body, the first drainage tube, and the second drainage tube are all made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By designing the first drainage tube and the second drainage tube in a nested layout, with the second drainage tube having a smaller diameter and located inside the first drainage tube, space utilization is optimized, making the entire device structure compact. In actual medical operations, doctors can use its compact structure to perform operations flexibly in a limited space, effectively reducing the obstacles caused by the large size of the instruments, reducing the risk of collision with surrounding tissues, and providing convenient conditions for precise treatment.

[0013] 2. The first drainage tube is connected to a constant temperature irrigation pressure pump, which delivers high-pressure water to a funnel-shaped drainage head made of silicone. This head can evenly cover and rinse various wounds, while the soft silicone material can avoid scratching fragile tissues. The second drainage tube is responsible for collecting waste fluid and contaminated blood. The groove in the limiting head precisely positions the second drainage tube, and the drainage port accelerates the diversion of waste fluid. The two work together to efficiently collect waste and ensure wound cleanliness. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figures 1-4 As shown, this utility model provides a disposable drainage and suction device technical solution:

[0021] The system includes a main body 1. A first connection port 2 is fixedly connected to one side of the main body 1. A first drainage tube 3 is snapped into the first connection port 2. A drainage head 4 is snapped into one end of the first drainage tube 3. Multiple sets of connecting rods 7 are fixedly installed inside the drainage head 4. Limiting heads 8 are fixedly connected between the connecting rods 7. A second drainage tube 9 is snapped into the limiting head 8. A third connection port 6 and a second connection port 5 are provided on the other side of the main body 1 to cooperate with the first drainage tube 3 and the second drainage tube 9. One end of the second drainage tube 9 is connected to the second connection port 5.

[0022] Specifically, the first connection port 2 on one side of the main body 1 is snapped into the first drainage tube 3 to ensure a secure connection. Then, one end of the first drainage tube 3 is snapped into the drainage head 4. Inside the drainage head 4, multiple sets of connecting rods 7 are fixed together to form a stable structure. Limiting heads 8 are also fixedly connected between the connecting rods 7. The second drainage tube 9 is snapped into the limiting head 8, completing the initial installation. A disposable sterile flushing tube is then connected to one end of the second drainage tube 9; this connection must be tight and leak-free. Next, the entire device is connected to the constant temperature infusion pressure pump. The third connection port 6 is used to connect to the high-pressure water output end of the pressure pump, while the second connection port 5 is used to connect to the input end of the aspirator. The constant temperature infusion pressure pump is started, and the high-pressure water generated by the pump enters the main body 1 through the third connection port 6, then passes through the first connection port 2 and the first drainage tube 3 to reach the drainage head 4. The high-pressure water is then sprayed from the drainage head 4. The procedure involves rinsing fractured or infected wounds to remove waste fluids, blood, and other impurities. During rinsing, the mixture of waste fluids and blood is carried by the water flow through the drainage head 4 into the second drainage tube 9. The second drainage tube 9 guides this mixture to the main body 1, where it is then sucked in by the suction device through the second connection port 5, thus achieving the recovery of waste fluids and blood. The high-pressure water flow generated by the constant-temperature irrigation pressure pump can powerfully rinse the wound, effectively removing impurities such as necrotic tissue, bacteria, and foreign objects, ensuring a clean and tidy wound and creating a good environment for wound healing. Compared with traditional rinsing methods, this method greatly improves cleaning efficiency and effectiveness, promptly removing waste fluids and blood from the wound and reducing the possibility of bacterial growth. In the treatment of fractured or infected wounds, reducing the risk of infection is crucial for promoting wound healing and reducing the occurrence of complications.

[0023] The second drainage tube 9 is located inside the first drainage tube 3. The diameter of the second drainage tube 9 is smaller than that of the first drainage tube 3. The limiting head 8 is provided with a groove for use with the second drainage tube 9. A drainage port for use with the second drainage tube 9 is opened on one side of the limiting head 8. The drainage head 4 has a funnel-shaped structure and is made of silicone. The main body 1, the first drainage tube 3, and the second drainage tube 9 are all made of rubber.

[0024] Specifically, the first drainage tube 3 is responsible for delivering high-pressure flushing water, while the second drainage tube 9 is responsible for collecting waste fluid and contaminated blood. The smaller diameter of the second drainage tube 9, located inside the first drainage tube 3, does not affect the efficient output of high-pressure water for flushing, while simultaneously removing waste generated during flushing, ensuring the wound remains clean. The groove within the limiting head 8 fits tightly with the second drainage tube 9, providing precise positioning and preventing it from shaking or shifting during use. This is crucial for ensuring that waste fluid and contaminated blood are accurately drawn into the second drainage tube 9, especially in complex wound environments; a stable connection ensures... It ensures reliable suction effect and avoids waste liquid leakage or poor suction due to unstable connection. The funnel-shaped drainage head 4 has a large opening, which can better fit wounds of different shapes and sizes. Especially in the irrigation of fractures or large infected wounds, it can ensure that the high-pressure water flow evenly covers the entire wound without leaving any dead corners. The silicone material is soft and will not cause secondary damage to the wound. Even when in close contact with the wound, it can ensure patient comfort and avoid scratching the fragile wound tissue due to the instrument being too hard. The rubber material has excellent flexibility, which allows the main body 1 and the drainage tube to adapt to different operating angles and bending requirements during use.

[0025] The working principle of this utility model is as follows:

[0026] First, the first drainage tube 3 and the second drainage tube 9 are nested together. The diameter of the second drainage tube 9 is smaller than that of the first drainage tube 3 and it is located inside the first drainage tube 3. This structure achieves efficient use of space and makes the entire device compact.

[0027] Secondly, the first drainage tube 3 is connected to the constant temperature irrigation pressure pump, which is responsible for delivering high-pressure flushing water. When the pressure pump is started, the high-pressure water flows through the first drainage tube 3 to the drainage head 4. The drainage head 4 is funnel-shaped and made of silicone. The large opening can fit various wound surfaces, evenly cover and flush the wound. The soft silicone material avoids scratching fragile tissues. At the same time, the second drainage tube 9 is responsible for collecting waste liquid and contaminated blood. The groove in the limiting head 8 accurately positions the second drainage tube 9 to ensure its stability. The drain outlet accelerates the diversion of waste liquid. With the suction effect of the second drainage tube 9, waste is efficiently collected, ensuring the cleanliness of the wound surface.

[0028] It is worth mentioning that the choice of materials for each component plays a key role in realizing the working principle. The main body 1 and the first and second drainage tubes 9 are made of rubber. The wear resistance and corrosion resistance of rubber can withstand the long-term erosion of high-pressure water flow and waste liquid chemicals, ensuring the durability of the instrument. The silicone material of the drainage head 4 not only fits the wound surface to expand the irrigation range, but also, due to its smooth surface, helps waste liquid and blood flow smoothly, improving drainage efficiency.

[0029] Finally, the disposable drainage and suction device completes the cleaning treatment of fracture wounds, infected wounds, etc. through the coordinated operation of rinsing and suction functions. The high-pressure water flow rinses the wound to remove impurities, and the second drainage tube 9 promptly removes waste fluid and contaminated blood, forming a complete working closed loop, creating good conditions for wound healing, reducing the risk of infection, and promoting patient recovery.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
