DETAILED DESCRIPTION

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0030] According to one aspect of the utility model:

[0031] like Figure 1 and Figure 3 As shown, a storage box 5 is fixedly connected to the left side of the disinfection box 1, and a support plate 6 is fixedly connected to the storage box 5, the support column 403 and the lower surface of the disinfection box 1. A push rod 7 is fixedly connected to the left side of the support plate 6. The front and rear surfaces of the support plate 6 are rotatably connected to a moving wheel 8 through a rotating shaft. A micro air pump 9 is fixedly connected to the left side of the upper surface of the storage box 5. A drainage hose 10 is detachably connected to the top end of the output shaft of the micro air pump 9, and a ball 11 is fixedly connected to the right end of the drainage hose 10. A liquid storage tank 12 is arranged inside the storage box 5, and a vertical pipe 13 is arranged on the left side inside the liquid storage tank 12. The top end of the vertical pipe 13 extends to the top of the liquid storage tank 12 and is detachably connected to the bottom end of the output shaft of the micro air pump 9.

[0032] The push rod 7 makes it convenient for medical staff to push the entire device, improves the mobility of the device, and enables it to be flexibly used in different nursing scenarios. The multiple moving wheels 8 are further provided to further enhance the maneuverability of the device, allowing medical staff to easily move the device to the required position. The disassembly connection method between the top of the output shaft of the micro air pump 9 and the drainage hose 10 can make it more convenient and quick when the drainage hose 10 needs to be replaced or the micro air pump 9 needs to be maintained. At the same time, the ball 11 is provided as the drainage inlet, which is convenient for placement in a suitable drainage position. At the same time, the shape of the ball 11 may help prevent tissue or other foreign matter from clogging the drainage hose 10 during the drainage process. The waste liquid generated by the drainage is transported to the inside of the liquid storage tank 12 through the vertical pipe 13 for centralized storage, so that the device can meet various drainage needs in surgical care and improve the efficiency and quality of care.

[0033] like Figure 1 and Figure 4 As shown, the front surface of the storage box 5 is rotatably connected to a box door 23 through a hinge, and the front surface of the box door 23 and the front surface of the liquid storage box 12 are integrally formed with a transparent observation window 24;

[0034] The door 23 is provided to provide a convenient operation entrance for medical staff. When the storage box 5 needs to be inspected, cleaned or replaced, the door 23 can be easily opened, making the operation more convenient and quick. At the same time, when the door 23 is closed when not in use, it can also protect the liquid storage box 12, preventing external dust, debris, etc. from entering the storage box 5, keeping the liquid storage box 12 clean and hygienic, and the door 23 can also prevent the liquid storage box 12 from being accidentally hit or damaged, thereby extending the service life of the equipment.

[0035] like Figure 3 As shown, a plurality of moving wheels 14 are provided on the lower surface of the liquid storage box 12, and a limiting transverse groove 15 is provided on the left and right sides of the storage box 5, and a protrusion 16 is fixedly connected to the left and right sides of the liquid storage box 12, and the opposite sides of the two protrusions 16 extend to the inside of the two limiting transverse grooves 15 respectively;

[0036] The two limiting transverse grooves 15 cooperate with the two protrusions 16 to fix and guide the liquid storage tank 12. The sliding of the two protrusions 16 in the two limiting transverse grooves 15 limits the moving direction of the liquid storage tank 12, ensuring that the liquid storage tank 12 can be stably placed and moved in the storage box 5. At the same time, it can prevent the liquid storage tank 12 from shaking or tilting in the storage box 5, thereby ensuring the stability and safety of the drainage process. In particular, when the device is moved or subjected to external force, the cooperation of the two limiting transverse grooves 15 and the two protrusions 16 can effectively prevent the liquid storage tank 12 from shifting. When the drainage fluid inside the liquid storage tank 12 needs to be cleaned, the multiple moving wheels 14 can make the liquid storage tank 12 easily move in the storage box 5, reducing the burden of manual handling and improving the adaptability and flexibility of the device.

[0037] like Figure 4 As shown, a handle 27 is fixedly connected to the upper surface of the liquid storage tank 12 and located in front of the cylinder 21;

[0038] The handle 27 is provided to provide a convenient gripping point for medical personnel when operating the liquid storage tank 12. When the liquid storage tank 12 needs to be taken out of the storage box 5 or moved, the medical personnel can hold the handle 27 and easily operate the liquid storage tank 12, thereby improving the convenience and efficiency of the operation.

[0039] like Figure 1 and Figure 4 As shown, a filling port 25 is integrally formed at the front of the upper surface of the disinfection box 1, and a drain port 26 is integrally formed at the lower front surface of the disinfection box 1 and the lower front surface of the liquid storage box 12;

[0040] The addition port 25 and the two drainage ports 26 can make the drainage device more efficient and convenient during use. Medical staff can quickly add disinfectant to the interior of the disinfection box 1 and discharge waste disinfectant and drainage fluid, which reduces operation time, improves the efficiency of nursing work, facilitates cleaning and maintenance of the device, ensures the hygiene and disinfection effect of the device, and provides better protection for patient care.

[0041] like Figure 3 and Figure 7 As shown, an air suction box 17 is fixedly connected to the right side of the upper surface of the liquid storage tank 12, and an air pump 18 is fixedly connected to the upper surface of the air suction box 17. The output end of the air suction pump 18 is detachably connected to the U-shaped tube 2, and the input end of the air suction pump 18 extends to the upper part of the interior of the air suction box 17. A through-type ventilation groove 19 is provided on the upper surface of the interior of the liquid storage tank 12 and below the air suction box 17. A liquid level sensor 20 is fixedly connected to the upper left side of the interior of the liquid storage tank 12. A cylinder 21 is fixedly connected to the upper surface of the liquid storage tank 12 and located on the left side of the air suction box 17. A sealing baffle 22 is fixedly connected to the right end of the output shaft of the cylinder 21, and the right side of the sealing baffle 22 extends to the interior of the air suction box 17.

[0042] The waste gas generated by the internal drainage of the liquid storage tank 12 is transported to the interior of the disinfection box 1 through the U-shaped tube 2 through the set vacuum pump 18 and the ventilation groove 19, so as to be preliminarily purified by the disinfectant inside the disinfection box 1. The set liquid level sensor 20 can prevent the liquid storage tank 12 from being overfilled, and avoid equipment damage or safety accidents caused by excessive drainage of waste liquid. At the same time, by real-time monitoring of the liquid level, medical staff can better understand the drainage situation, adjust the drainage speed in time or take other measures to ensure the safety and treatment effect of the patient. When the waste liquid inside the liquid storage tank 12 is overfilled, the liquid level sensor 20 converts the liquid level information into an electrical signal output, and starts the cylinder 21 to control the movement of the sealing baffle 22, so that the ventilation groove 19 can be sealed by the sealing baffle 22, thereby preventing the waste liquid from entering the interior of the suction box 17, ensuring safety and stability during use.

[0043] like Figure 1 As shown, a surgical drainage device for nursing is provided, comprising a disinfection box 1, a U-shaped tube 2 is fixedly connected to the inner upper surface of the disinfection box 1, the bottom end of the right side of the U-shaped tube 2 extends to the lower part of the disinfection box 1, an air supply pipe 3 is fixedly connected to the upper right side of the disinfection box 1, and a sterilization mechanism 4 is fixedly connected to the right end of the air supply pipe 3;

[0044] The waste gas generated by the drainage is transported to the interior of the disinfection box 1 through the U-shaped tube 2, and the waste gas that has been preliminarily purified enters the interior of the sterilization mechanism 4 through the air supply pipe 3 for the final purification operation, which completely kills the bacteria, viruses and other microorganisms in the gas, thereby ensuring the safety and reliability of the waste gas removal.

[0045] like Figure 2 , Figure 5 and Figure 6As shown, the sterilization mechanism 4 includes a light box 401, and a plurality of wind baffles 402 are symmetrically fixedly connected to the outer wall of the upper inner part of the light box 401, a support column 403 is fixedly connected at the center of the lower surface of the light box 401, and a driving motor 404 is fixedly connected to the inside of the support column 403, and the top of the output shaft of the driving motor 404 extends to the inside of the light box 401 and is fixedly connected to a bevel gear 1 405, an exhaust port 406 is integrally formed at the lower right side of the light box 401, and a rotating rod 407 is fixedly connected at the center of the upper surface of the bevel gear 1 405, and the top of the rotating rod 407 is rotatably connected to the inner upper surface of the light box 401 through a rotating shaft, and the upper and lower outer walls of the rotating rod 407 are symmetrically fixedly connected to mounting plates 40 8. Multiple mounting plates 408 are detachably connected to one side of multiple wind baffles 402 with ultraviolet disinfection lamps 409. Multiple mounting plates 408 are slidably connected to the inner wall of the light box 401. A fixed plate 410 is fixedly connected to the inside of the exhaust port 406. A plurality of through-type exhaust circular holes 411 are provided on the right side of the fixed plate 410. A rotating plate 412 is rotatably connected to the left side of the fixed plate 410 through a rotating shaft. A plurality of through-type exhaust circular holes 413 are provided on the left side of the rotating plate 412. A transmission rod 414 is fixedly connected to the left center of the rotating plate 412. A bevel gear 415 is fixedly connected to the left end of the transmission rod 414. The outer wall of the bevel gear 415 is meshed with the outer wall of the bevel gear 405.

[0046] When the waste gas generated by the drainage is transported to the top of the lamp box 401 through the air supply pipe 3, the bevel gear 1 405 is driven to rotate by the drive motor 404, and the multiple mounting plates 408 can be controlled to rotate by the rotating rod 407, thereby driving the multiple ultraviolet disinfection lamps 409 to rotate at the same time, thereby improving the sterilization effect. At the same time, the multiple wind baffles 402 are provided to guide the airflow and separate the space. During the sterilization process, the multiple wind baffles 402 can increase the distance of the airflow flow, thereby further improving the sterilization effect. The multiple wind baffles 402 are all made of quartz glass. Ultraviolet rays will pass through the wind baffles 402 to better purify the gas. When the bevel gear 1 405 rotates, it will also drive the bevel gear 2 415 to rotate at the same time. The bevel gear 2 415 controls the rotation of the rotating disk 412 through the transmission rod 414, so that the multiple exhaust holes 2 413 can be indirectly aligned with the multiple exhaust holes 1 411, thereby indirectly controlling the exhaust of the gas, so that the gas can achieve a better sterilization effect, and ensure that the sterilized gas can be discharged safely and effectively.
