[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0026] like Figures 1 to 4 As shown, a drainage device for clinical care of critically ill patients includes a drainage box 10, a drainage port 11 at the top of the drainage box 10, and a connector 20 fixed above the drainage port 11. A negative pressure connection groove 12 is provided on one side of the drainage box 10, and a negative pressure device 30 is slidably connected within the negative pressure connection groove 12.
[0027] The suspension mechanism 40 includes a collar 41, which is fixedly sleeved on the outside of the drainage box 10 and located above the negative pressure connection groove 12. An adjusting plate 42 is mounted above the collar 41. The top of the adjusting plate 42 has an adjusting groove 421. An adjusting ring 43 is rotatably connected in the adjusting groove 421. The adjusting ring 43 has a threaded hole, which is threadedly connected to an adjusting screw 431. One end of the adjusting screw 431 is fixed with a fixing plate 44.
[0028] The device is suspended in different locations by rotating the adjusting ring 43, which in turn drives the adjusting screw 431 to rotate through the screw thread. This causes the fixed plates 44 located at both ends of the ring to move and cooperate with the adjusting plate 42 to form a clamp. Through the cooperation of the adjusting plate 42 and the fixed plate 44, the device can be suspended in different places to prevent accidental contact in the ward and avoid tipping and backflow caused by accidental collisions.
[0029] Specifically, when suspending the drainage box 10 at the edge of the hospital bed, the distance between the adjusting plate 42 and the fixing plate 44 is adjusted so that the distance between the adjusting plate 42 and the fixing plate 44 can be adapted to the width of the bed edge. Regardless of whether the cross-sectional shape of the bed edge is circular, square or rectangular, the drainage box 10 can be suspended by the adjusting plate 42 and the fixing plate 44. Here, the bed edge refers to the supporting element at the outermost edge of the hospital bed, which can be in the form of a square rod, a round rod or a plate.
[0030] It should be noted that anti-slip textures are provided on the outer side of the adjusting ring 43. These textures increase friction during adjustment, ensuring precise adjustment when the adjusting ring 43 is rotated. The negative pressure device 30 is an electric medical negative pressure suction device, ensuring precise adjustment of the negative pressure inside the drainage box 10 during negative pressure adjustment.
[0031] like Figure 2 , Figure 4 As shown, a drive screw 411 is rotatably mounted inside the collar 41. The drive screw 411 has a threaded section at its top, which is threadedly connected to the bottom of the adjusting plate 42. When the drive screw 411 is rotated clockwise, it interacts with the threaded hole at the bottom of the adjusting plate 42, causing the adjusting plate 42 to move upwards, effectively adjusting the working height of the suspension mechanism 40. Conversely, when the drive screw 411 is rotated counterclockwise, it causes the adjusting plate 42 to move downwards.
[0032] Preferably, sliding rods 422 are fixed on both sides of the bottom of the adjusting plate 42, and the sliding rods 422 are slidably connected to the top of the collar 41. The sliding rods 422, in conjunction with the sliding holes on the collar 41, ensure the smoothness and safety of the adjusting plate 42 during raising and lowering.
[0033] like Figure 2 , Figure 4 As shown, a limiting plate 45 is fixed to the other end of the adjusting screw 431. A support rod 46 is fixed between the limiting plate 45 and the fixed plate 44, and the support rod 46 is slidably connected to the upper part of the adjusting plate 42. When the adjusting screw 431 moves the fixed plate 44, the support rod 46 is slidably connected to the hole in the upper part of the adjusting plate 42, which ensures the stability of the fixed plate 44 during adjustment.
[0034] Preferably, a protective pad made of rubber is provided on the side of the fixed plate 44 near the adjusting plate 42. The protective pad also has uniformly distributed anti-slip textures on the side of the protective pad near the adjusting plate 42. These anti-slip textures increase friction during fixing, ensuring stability during suspension.
[0035] like Figure 2 , Figure 4As shown, a control valve is fixed above the negative pressure connection groove 12, and a negative pressure pipe is slidably connected inside the control valve. The negative pressure pipe is fixed to the output end of the negative pressure device 30.
[0036] Furthermore, when the negative pressure tube is connected to the control valve, the control valve is in the open state, and the negative pressure device 30 can effectively regulate the negative pressure inside the drainage box 10. When the negative pressure tube is separated from the control valve, the control valve is in the closed state, which can effectively ensure the sealing of the drainage box 10, prevent the backflow of drainage fluid and the entry of external contaminants, and improve the safety of use.
[0037] like Figure 2 , Figure 4 As shown, a drainage tube 21 is fixed above the connector 20, and a fixator 22 is slidably provided on the outside of the drainage tube 21. The fixator 22 includes an attachment base 221, and a fixing buckle 222 is hinged to the attachment base 221. By attaching the attachment base 221 to the patient's body and cooperating with the fixing buckle 222, the drainage tube 21 can be clamped and fixed, ensuring that the drainage tube 21 will not slip or fall off during drainage, thus improving the safety and stability of the drainage process.
[0038] Preferably, a sensor is fixed inside the connector 20 and electrically connected to the alarm, with the alarm fixed above the connector 20. The sensor allows for real-time monitoring of the drainage fluid flow and pressure. By connecting to the alarm, it effectively triggers an alarm when drainage is obstructed or excessive, thus improving safety during drainage.
[0039] The working principle of this utility model is as follows: When the drainage box 10 needs to be suspended, the adjusting ring 43 is rotated, causing the adjusting ring 43 to rotate in relation to the adjusting groove 421 on the adjusting plate 42. An adjusting screw 431 is threadedly connected to the adjusting ring 43, and a fixing plate 44 is fixed to one end of the adjusting screw 431. When the adjusting ring 43 is rotated clockwise, the adjusting ring 43 interacts with the thread on the adjusting screw 431 through the threaded hole, thereby driving the adjusting screw 431 to move the fixing plate 44 closer to the adjusting plate 42, forming a clamping action. Conversely, when the adjusting ring 43 is rotated counterclockwise, the fixing plate 44 is moved away from the adjusting plate 42. Clockwise rotation of the drive screw 411 moves the adjusting plate 42 upwards, effectively adjusting the height of the suspension mechanism 40. Conversely, counterclockwise rotation of the drive screw 411 moves the adjusting plate 42 downwards. Ensure that the drainage box 10 is suspended during drainage to reduce the risk of accidental tipping and backflow.
[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
