Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sputum drainage device. Background Technology

[0002] Tracheotomy is a surgical procedure in which an artificial airway is created by cutting open the trachea in the neck and inserting a metal or silicone tracheostomy tube.

[0003] After a tracheotomy, the patient loses the normal protective function of the airway, making it prone to sputum accumulation. It is necessary to drain the sputum promptly to maintain an unobstructed airway. Current techniques for tracheotomy sputum drainage include postural drainage, suctioning, and suction devices. Suction devices primarily work by inserting a suction tube into the trachea and using a suction pump under negative pressure to draw sputum through the tube into a collection bottle.

[0004] During tracheostomy suctioning, the suction catheter, under the negative pressure provided by the suction device, experiences inward pulling, making it prone to movement. This movement increases mechanical irritation and damage to the tracheal mucosa, leading to a risk of bleeding or infection, and also produces more sputum. Furthermore, existing suction devices are relatively large, inconvenient to move and carry, and therefore inconvenient to use.

[0005] Therefore, there is an urgent need for a sputum drainage device that is easy to carry, highly adaptable, and can effectively reduce the risk of infection to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a sputum drainage device that is simple in structure, portable, highly adaptable, and can effectively reduce the risk of infection.

[0007] To achieve the above objectives, this utility model discloses a sputum drainage device, comprising a base, a fixing cylinder and a negative pressure device mounted on the top of the base, and casters mounted on the bottom of the base, as well as a positioning assembly. The fixing cylinder is used to hold a collection cup, and the sealing cap of the collection cup is provided with a liquid guide port and an air suction port. The liquid guide port is used for connecting the outlet end of the suction tube, and the air suction port is used for connecting the suction tube of the negative pressure device. The positioning assembly includes a telescopic rod, a first universal ball joint, a fixing block, a second universal ball joint, a drive plate, and a clamping plate connected in sequence. The bottom of the telescopic rod is rotatably connected to or slidably mounted on the outer wall of the fixed cylinder or the top of the base. The first universal ball is mounted between the top of the telescopic rod and the bottom of the fixed block. Two second universal balls are symmetrically arranged on the two opposite side walls of the fixed block. The bottoms of the two drive plates are symmetrically mounted on the two second universal balls. A clamping plate is fixedly connected to the top of each drive plate. The shape of the clamping surface of the clamping plate corresponds to the shape of the suction tube. A first elastic element is also provided between the drive plate and the fixed block.

[0008] Preferably, the drive plate is V-shaped or L-shaped. This shape of drive plate has a simple structure and is easy for medical personnel to operate.

[0009] Preferably, each of the clamping plates has a floating plate arranged parallel to and spaced apart on its inner side, and a second elastic element is provided between the clamping plate and the floating plate. Through the cooperation of the second elastic element and the floating plate, the clamping plate can adaptively adjust according to the diameter of the suction tube, ensuring a tight fit between the clamping plate and the suction tube. This prevents damage to the suction tube due to excessive tightness, nor instability due to excessive looseness.

[0010] Preferably, both the clamping plate and the floating plate are arc-shaped, the length of the floating plate is less than the length of the clamping plate, and the floating plate is a flexible plate or the clamping surface of the floating plate is provided with a flexible layer.

[0011] Preferably, a storage box is also installed on the top of the base or the side wall of the fixed cylinder. The telescopic rod, through telescopic, rotating, or sliding movements, drives the positioning component, either wholly or partially, into the storage box. The storage box allows for the storage of the positioning component when not in use, effectively reducing the risk of cross-contamination and environmental pollution caused by the telescopic rod and clamping plate of the positioning component being exposed to the outside.

[0012] Preferably, a disinfection box is also installed on the top of the base. The disinfection box sprays disinfectant into the fixed cylinder through a first disinfection pipe and a first nozzle connected to the output end of the first disinfection pipe. The output end of the first disinfection pipe is connected to an annular pipe, which is installed on the top of the fixed cylinder. Multiple first nozzles are arranged at intervals in the annular pipe. By spraying disinfectant into the fixed cylinder through the first disinfection pipe and the first nozzles, the fixed cylinder, collection cup, and its sealing cap are sterilized, reducing the risk of infection to patients due to contact with contaminated equipment, reducing the spread of pathogens and cross-infection among patients, thereby increasing the safety of use. The arrangement of multiple first nozzles in the annular pipe makes the spraying of disinfectant more uniform and the disinfection effect better.

[0013] Preferably, a disinfection box is also installed on the top of the base. The disinfection box sprays disinfectant into the storage box through a second disinfection pipe and a second nozzle connected to the output end of the second disinfection pipe. Spraying disinfectant into the storage box through the second disinfection pipe and the second nozzle sterilizes components such as the storage box, the telescopic rod of the positioning assembly, and the clamping plate, reducing the risk of infection for patients due to contact with contaminated equipment, minimizing the spread of pathogens and cross-infection among patients, thereby increasing safety during use.

[0014] Preferably, the inner bottom wall of the fixing cylinder is provided with multiple annular grooves of varying diameters, which are concentrically arranged and arranged at different heights along the height direction of the fixing cylinder. The multiple concentric annular grooves enable the fixing of collection cups of different sizes, effectively improving adaptability and meeting different usage needs.

[0015] Preferably, the inner wall of the fixing cylinder is provided with at least two third elastic members arranged at equal angles on its periphery. Each of the third elastic members has a positioning plate connected to its end, and the shape of the positioning plate matches the outer contour of the collecting cup. Through the third elastic members and the positioning plates, the collecting cup can be effectively fixed, facilitating flexible replacement, and can also be fixed to collecting cups of different sizes, effectively improving adaptability and meeting different usage needs.

[0016] Preferably, the top of the base is surrounded by a protective railing, which is equipped with a retractable hook for attachment. With the protective railing and the retractable hook, the entire device can be suspended beside the hospital bed or inside a mobile vehicle during field visits, and the attachment height can be adjusted as needed for easy transport.

[0017] Compared with the prior art, the beneficial effects of the sputum drainage device of this utility model are as follows: Firstly, by operating the drive plate, the suction tube can be quickly fixed on the two clamping plates, so that the suction tube maintains stability during the suctioning process, which can effectively reduce the risk of tracheal damage or infection caused by the movement of the suction tube, and facilitate the operation of medical staff, effectively improving work efficiency and reducing the workload of medical staff; Secondly, through the cooperation of the first elastic element and the drive plate, the clamping plates can fix suction tubes of different diameters, effectively improving the adaptability of this device; Thirdly, the height of the clamping plates can be easily and quickly adjusted by the telescopic rod, and the angle of the clamping plates can be flexibly adjusted by the first universal ball and the second universal ball, further improving the adaptability of this device; In addition, the fixing cylinder and the negative pressure device are located on the top of the base, and the bottom of the base is equipped with universal wheels, which facilitates movement, transportation and carrying when going out.

[0028] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] See Figures 1 to 10 This invention provides a sputum drainage device 100, suitable for draining sputum from a tracheostomy site. Generally, the sputum drainage device 100 includes a base 10, a fixing cylinder 20 and a negative pressure device 30 mounted on the top of the base 10, casters 80 mounted on the bottom of the base 10, and a positioning assembly 50. The fixing cylinder 20 houses a collection cup 40, which collects sputum suctioned by a suction tube 200. The collection cup 40 is an open cup, and its sealing cap 41, used to close the cup opening, has a liquid inlet 411 and an air suction port 412. The liquid inlet 411 is used to connect the outlet end of the suction tube 200, and the air suction port 412 is used to connect the air suction tube 31 of the negative pressure device 30. The sealing cap 41 also has an exhaust port 413, in which a rubber stopper 42 for pressure relief is installed. The positioning assembly 50 includes a telescopic rod 51, a first universal ball joint 52, a fixing block 53, a second universal ball joint 54, a drive plate 55, and a clamping plate 56 connected in sequence. The bottom of the telescopic rod 51 is rotatably connected to or slidably mounted on the outer wall of the fixing cylinder 10 or the top of the base 10. The first universal ball joint 52 is installed between the top of the telescopic rod 51 and the bottom of the fixing block 53. Two second universal balls joint 54 are symmetrically arranged on the two opposite side walls of the fixing block 53. Two drive plates 55 are symmetrically installed on the two second universal balls joint 54. A clamping plate 56 is fixedly connected to the top of each drive plate 55. The shape of the clamping plate 56 corresponds to the shape of the suction tube 200. A first elastic element 57 is also provided between the drive plate 55 and the fixing block 53.

[0030] The casters 80 are retractable and extendable at the bottom of the base 10, allowing the placement height of the base 10 relative to the mounting surface to be adjusted as needed. Figure 9 As shown, a telescopic tube 81 is connected between the base 10 and the caster 80, thereby adjusting the height by adjusting the connection depth between the two sleeves of the telescopic tube 81. In addition, the sputum drainage device 100 disclosed in this application is also electrically connected to a controller (not shown in the figure), which controls the operation of the device, further improving the automation level of the sputum drainage device 100. The controller is an existing controller, and its structure and control principle are well known in the art, and will not be described in detail here.

[0031] During operation, the collection cup 40 is placed in the fixed cylinder 10, and the suction tube 31 is connected to the suction port 412 to connect the negative pressure device 30 and the collection cup 40. The outlet end of the suction tube 200 is connected to the drainage port 411. When performing sputum drainage, the inlet end of the suction tube 200 is inserted along the trachea. When the inlet end is inserted into the sputum position, the telescopic rod 51 is stretched to move the clamping plate 56 to the required height position. The clamping plate 56 is rotated to make the fixed block 53 rotate by means of the first universal ball 52 to rotate the clamping plate 56 to the required angle. By grasping the two drive plates 55, the second universal ball is used to rotate the clamping plate 56 to the required angle. Ball 54 causes the two clamping plates 56 to open to relatively far apart sides; wherein, the first universal ball 52 and the second universal ball 54 are both equipped with a friction damping system inside, and the first elastic element 57 stores pressure under the compression of the drive plate 55. After the suction tube 200 is placed between the two clamping plates 56, the two drive plates 55 are released. Under the action of the restoring force of the two first elastic elements 57, the two clamping plates 56 move closer to each other to clamp the suction tube 200 between them, thereby fixing the suction tube 200 in the designated position; then, the negative pressure device 30 is activated, and the sputum is drawn into the collection cup 40 through the suction tube 200.

[0032] See below Figures 1 to 8 The specific structure and working principle of the first embodiment of the sputum drainage device 100 of this utility model will be described below: See Figure 1 Specifically, in this embodiment, the base 10 is a square or circular base. The shape of the fixing cylinder 20 corresponds to the shape of the collecting cup 40, both being square or circular.

[0033] See Figure 2 Specifically, in this embodiment, the bottom inner wall of the fixing cylinder 20 is provided with a plurality of annular grooves 20a of different diameters. The plurality of annular grooves 20a are arranged concentrically and arranged at different heights along the height direction of the fixing cylinder 20, thereby being suitable for fixing collection cups 40 of different sizes and effectively improving the adaptability of the device.

[0034] See Figure 2 and Figure 7Specifically, in this embodiment, at least two third elastic members 21 arranged at equal angles are provided on the periphery of the inner wall of the fixed cylinder 20. Each end of the third elastic member 21 is connected to a positioning plate 22. The shape of the positioning plate 22 matches the shape of the outer contour of the collection cup 40, specifically an arc-shaped plate, a straight plate, or an L-shaped plate. The third elastic member 21 is specifically a compression spring and is arranged radially along the fixed cylinder 20. In actual use, the at least two positioning plates 22, with the help of the extensibility of the third elastic members 21, fix collection cups 40 of different sizes in the fixed cylinder 20, facilitating flexible replacement of the collection cups 40 to meet different usage needs, effectively improving adaptability, and ensuring that the collection cups 40 remain stable during use, effectively improving the continuity and stability of the suctioning operation.

[0035] Furthermore, when the fixed cylinder 20 has multiple annular slots 20a arranged at different heights and of different sizes on the bottom wall, and positioning plates 22 are arranged at equal angles around the inner wall of the cylinder, the collecting cup 40 is fixed from the upper and lower opposite sides, thereby further improving the stability of the positioning.

[0036] See Figure 3 Specifically, in this embodiment, the top of the negative pressure device 30 is provided with a fixing ring 32, which is sleeved on the outside of the connection port 33. The connection port 33 is connected to the negative pressure pump (not shown in the figure due to obstruction) through a pipeline. The height of the fixing ring 32 is greater than the height of the connection port 33, and the top end of the fixing ring 32 is relatively inward. A sealing ring 34 is sleeved on the outside of the opposite end of the suction pipe 31 to seal the connection between the suction pipe 31 and the connection port 33. During operation, as the corresponding ends of the suction tube 31 are inserted into the connection port 33, the sealing ring 34 moves down above the fixing ring 32. Under the action of the downward insertion force and the squeezing force of the top port of the fixing ring 32, the sealing ring 34 elastically contracts and enters the fixing ring 32. It then fits tightly against the inner wall of the fixing ring 32 and the end of the connection port 33, thus firmly fixing the corresponding ends of the suction tube 31 in the connection port 33. This effectively fills the gap between the connection port 33 and the suction tube 31, ensuring a stable negative pressure inside the negative pressure device 30. This reduces the risk of the suction tube 31 falling off and leaking due to pressure changes during suctioning, thereby reducing irritation and damage to the patient's respiratory tract and improving the suctioning effect.

[0037] Of course, the negative pressure device 30 also includes a protective housing 35, on which a switch 36 and a pressure gauge 37 are installed. The switch 36 and the pressure gauge 37 are respectively connected to a controller. The controller is also connected to a motor and a negative pressure pump located inside the protective housing 35. The motor drives the negative pressure pump to operate. Specifically, a miniature negative pressure pump can be used. After the switch 36 is activated, the negative pressure pump extracts the gas from the collection cup 40. During the extraction process, the pressure value is controlled by the pressure gauge 37, so that the sputum is drawn into the suction tube 200 and flows into the collection cup 40 through the suction tube 200, thereby completing the sputum suction operation.

[0038] Combination Figure 3 and Figure 4 It should be noted that in this embodiment, the collection cup 40 is a disposable item. After suctioning, it is removed from the fixing tube 20 for processing, while the sealing cap 41 that seals it is reusable. In actual use, the suction tube 31 can be pre-connected to the sealing cap 41 and the negative pressure device 30. Each time it is used, the sealing cap 41 is placed on the mouth of the collection cup 40, and the suction tube 200 is connected accordingly. The sealing cap 41 connected to the suction tube 31 can be stored in the reserved slot on the protective shell 35 of the negative pressure device 30 when not in use. Alternatively, it can be... Figure 4 As shown, the support frame 38 is hung above the fixed cylinder 20. When in use, it is pulled down to cover the collection cup 40, and then the suction tube 31 is connected to the suction tube 200. Alternatively, the sealing cap 41 connected to the suction tube 31 is hung above the fixed cylinder 20. When in use, it is pulled down to cover the collection cup 40, and then the suction tube 200 is connected.

[0039] See Figures 4 to 6 Specifically, in this embodiment, the positioning component 50 is mounted on the fixed cylinder 20 and rotatably connected to the outer wall of the fixed cylinder 20. Specifically, the outer wall of the fixed cylinder 20 has an outwardly protruding rib 23, and the bottom of the telescopic rod 51 is rotatably connected to the rib 23 via a pivot. The telescopic rod 51 is a manual telescopic rod; the length of the telescopic rod 51 is adjusted by manually adjusting the fitting depth between the inner and outer sleeves, thereby sending the clamping plate 56 to the required height. This design is simple, easy to operate, and low in cost. Of course, the telescopic rod 51 can also be an electric telescopic rod or a pneumatic telescopic rod.

[0040] See Figure 5 and Figure 6 Specifically, the drive board 55 is V-shaped or L-shaped for easy operation by medical staff. For example, Figure 5 As shown, the first elastic element 57 is a torsion spring, as... Figure 6 As shown, the first elastic element 57 is a compression spring, which can realize the action of storing energy under force and releasing it back. It has a simple structure and effectively reduces costs.

[0041] Specifically, in this embodiment, to enhance the stability of the suction tube 200 clamping and positioning, each clamping plate 56 has a floating plate 58 arranged parallel to and spaced apart from it on its inner side. A second elastic element 59 is provided between the clamping plate 56 and the floating plate 58 on the same side. The second elastic element 59 is specifically a compression spring, allowing the floating plate 58 to extend and retract relative to the clamping plate 56, thereby achieving adaptive adjustment. Both the clamping plate 56 and the floating plate 58 are arc-shaped, with the length of the floating plate 58 being less than the length of the clamping plate 56. The floating plate 58 is a flexible plate or has a flexible layer, such as a silicone layer or a rubber layer, on its clamping surface to achieve flexible clamping. During clamping operations, the cooperation between the second elastic element 59 and the floating plate 58 allows for adaptive adjustment according to the diameter of the suction tube 200, ensuring that the clamping plate 56 fits tightly against the suction tube 200, preventing damage due to excessive tightness or instability due to excessive looseness. (See reference...) Figure 1 and Figure 7 Specifically, in this embodiment, a storage box 60 is also installed on the top of the base 10 or the side wall of the fixing cylinder 20. The telescopic rod 51 is located above the storage box 10 and, through telescopic, rotating, or sliding movements, drives the positioning component 50, either wholly or partially, into the storage box 60. When not in use, the positioning component 50 is stored in the storage box 60, making the entire device neater and effectively reducing the exposure of components such as the telescopic rod 51 and the clamping plate 56 of the positioning component 50 to the outside, thus preventing cross-infection and environmental pollution.

[0042] like Figure 1 As shown, specifically, the storage box 60 is fixed to the lower side of the outer wall of the fixing cylinder 10, and the telescopic rod 51 is rotatably connected to the upper side of the outer wall of the fixing cylinder 10. The telescopic rod 51 rotates downward relative to the fixing cylinder 10 and enters the storage box 60 through the side opening. Specifically, the storage box 60 is a semi-closed square box with a top side opening and an outer side opening. Specifically, the storage box 60 includes a bottom plate 61, a left side plate 62, a rear side plate 63, a right side plate 64, and a front side plate 65. The left side plate 62, rear side plate 63, right side plate 64, and front side plate 65 surround the periphery of the bottom plate 61 and are connected in sequence to jointly enclose a storage space for the positioning component 50 to be placed. The front panel 65 is a split structure, including two baffles 651 that are connected one-to-one with the left side panel 62 and the right side panel 64. The two baffles 651 are arranged symmetrically, are both arc-shaped and elastic, and the gap between them forms a side opening.

[0043] During operation, after suctioning is completed, hold the two drive plates 55 to move the two clamping plates 56 away from each other, thus removing the suction tube 200 from the clamping plates 56. If necessary, retract the telescopic rod 51 and rotate it downwards. It first passes through the two baffles 651. When the two baffles 651 are compressed, they bend elastically, allowing the positioning component 50 to enter the storage box 60 for safekeeping. When using it again, rotate the telescopic rod 51 upwards, causing the positioning component 50 to press the two baffles 651 from the inside out. The two baffles 651 bend outwards under force, allowing the positioning component 50 to pass through the storage box 60 and move upwards. Then, adjust the length of the telescopic rod 51 and the angle of the clamping plates 56 as needed. At the same time, the baffles 651 return to their original position. The storage box 60 can effectively store unused components such as the telescopic rod 51 and clamping plate 56 of the positioning component 50, which can effectively reduce the problem of cross-infection and environmental pollution caused by exposure to the outside, and play the role of isolating pollution sources. It can also effectively reduce the impact and collision of external objects on the clamping plate 56, avoid damage to the clamping plate 56, and thus increase the overall service life.

[0044] See Figure 1 and Figure 7 Specifically, in this embodiment, the suction tube 200 is a disposable item that can be discarded after each use. To avoid contamination during use, a disinfection box 70 is also installed on the top of the base 10. The disinfection box 70 sprays disinfectant into the fixed cylinder 10 through the first disinfection tube 71 and the first nozzle 72 connected to the output end of the first disinfection tube 71, so as to sterilize the fixed cylinder 10, the collection cup 40 and its sealing cap 41, effectively reducing the risk of infection for patients due to contact with contaminated equipment, reducing the spread of pathogens and cross-infection between patients, thereby increasing the safety of use.

[0045] The first disinfection tube 71 is connected to an annular tube 73 at its output end. The annular tube 73 is installed on the top of the fixed cylinder 10. Multiple first nozzles 72 are arranged alternately in the annular tube 73, which makes the spraying of disinfectant more uniform and the disinfection effect better.

[0046] Specifically, the disinfection box 70 also sprays disinfectant into the storage box 60 through the second disinfection tube 74 and the second nozzle 75 connected to the output end of the second disinfection tube 74. This disinfects the storage box 60, the telescopic rod 51 of the positioning component 50, and the clamping plate 56, effectively reducing the risk of infection for patients due to contact with contaminated equipment, reducing the spread of pathogens and cross-infection among patients, thereby increasing the safety of use. The output end of the second disinfection tube 74 passes through the side wall of the storage box 60, allowing the second nozzle 75 to enter the storage box 60.

[0047] In addition, the disinfection tank 70 also includes a spray pump connected to the first disinfection pipe 71 and the second disinfection pipe 74, used to deliver the disinfectant solution inside the tank into the first disinfection pipe 71 and the second disinfection pipe 74. One-way valves are respectively installed on the first disinfection pipe 71 and the second disinfection pipe 74 to control the flow between the disinfectant solution inside the tank and the first spray head 72 and the second spray head 75. The disinfection tank 70 also has a replenishment port for adding disinfectant solution to the tank. A liquid level sensor is also installed inside the disinfection tank 70 to monitor the liquid level of the disinfectant solution inside the tank and to provide a reminder to replenish the disinfectant solution.

[0048] See Figure 8 Specifically, a protective railing 90 is also provided around the top edge of the base 10, and the protective railing 90 is equipped with a retractable hook 91 for hanging. In use, especially when used outside, the entire device can be suspended next to the hospital bed or inside a mobile vehicle by means of the retractable hook 91, and the length of the retractable hook 91 can be adjusted according to the needs of use to adapt to different hanging heights or hanging objects, thus facilitating use, especially during transportation.

[0049] See Figure 9 and Figure 10 In the second embodiment of the sputum drainage device 100 of this utility model, the main difference from the first embodiment lies in the installation position of the positioning component 50 and the specific structure of the storage box 60. In this embodiment, the positioning component 50 is installed on the top of the storage box 60. The storage box 60 can be directly installed on the base 10, or it can be installed on the fixing cylinder 20.

[0050] Specifically, in this embodiment, the bottom of the telescopic rod 51 is rotatably connected to or slidably mounted on the outer or inner wall of the storage box 60. For example... Figure 10 As shown, the storage box 60 is a square box with a top and side opening. The storage box 60 includes a base plate 61, a left side plate 62, a rear side plate 63, a right side plate 64, and a front side plate 65. The left side plate 62, rear side plate 63, right side plate 64, and front side plate 65 surround the periphery of the base plate 61 and are connected sequentially to create a storage space for the positioning component 50. Compared to the first embodiment, the front side plate 65 is an integral structure. The bottom of the telescopic rod 51 is rotatably connected to the top of the storage box 60 via a pivot shaft located on the outer or inner side wall of the top of the storage box 60. The retracted length of the telescopic rod 51 is less than the length of the top and side opening of the storage box 60. Specifically, the telescopic rod 51 is rotatably connected to the outer or inner wall of the left side plate 62, and correspondingly, the second nozzle 75 is located on the right side plate 64, thereby facilitating the disinfection of components such as the telescopic rod 51, the drive plate 54, the clamping plate 56 and the floating plate 58 that are in contact with the suction tube 200.

[0051] During operation, after suctioning is completed, hold the two drive plates 55 to move the two clamping plates 56 away from each other, allowing the suction tube 200 to be removed from the drive plates 55. If necessary, retract the telescopic rod 51 and rotate it clockwise downwards to allow the positioning component 50 to enter the storage box 60. The storage box 60 stores the positioning component 50, and the second nozzle 75 disinfects it. For reuse, rotate the telescopic rod 51 counterclockwise upwards, causing the positioning component 50 to rotate upwards until it passes through the storage box 60. Adjust the length of the telescopic rod 51 and the angle of the clamping plates 56 as needed. The storage box 60 effectively stores unused components such as the telescopic rod 51 and clamping plates 56, reducing cross-infection and environmental pollution caused by external exposure. It also effectively reduces impact and collisions to the clamping plates 56 from external objects, minimizing damage and increasing their lifespan.

[0052] Compared with the prior art, the beneficial effects of the sputum drainage device 100 of this utility model are as follows: On the one hand, by operating the drive plate 55, the suction tube 200 can be quickly fixed on the two clamping plates 56, so that the suction tube 200 maintains stability during the suctioning process, which can effectively reduce the risk of tracheal damage or infection caused by the movement of the suction tube 200, facilitate the operation of medical staff, effectively improve work efficiency and reduce the workload of medical staff; on the other hand, by cooperating with the first elastic member 57 and the drive plate 55, the clamping plate 56 can fix suction tubes 200 of different diameters, effectively improving the adaptability of this device; furthermore, the height of the clamping plate 56 can be conveniently and quickly adjusted by the telescopic rod 51, and the angle of the clamping plate 56 can be flexibly adjusted by the first universal ball 52 and the second universal ball 54, further improving the adaptability of this device; in addition, the fixing cylinder 20 and the negative pressure device 30 are located on the top of the base 10, and the bottom of the base 10 is provided with universal wheels 80, which facilitates movement, transportation and carrying when going out.
