Description

Technical Field

[0001] The utility model relates to the technical field of drainers, in particular to a negative pressure drainer. Background Art

[0002] Negative pressure drainers are generally used in hospital clinical surgical emergencies for sputum suction, uterine curettage in obstetrics and gynecology, suction of blood during surgery, intra-abdominal fluid, and smoke generated by an electrosurgical unit, etc.

[0003] Existing technologies such as the utility model with the publication number CN219662438U disclose a negative pressure drainer, which includes a main body, a connection seat, and a fixing component. Installation plates are symmetrically and fixedly installed at the top and bottom of the main body. A connection seat is arranged on one side of the top of the installation plate on the top side. The bottom of the connection seat is fixedly installed with left and right inlet pipes. The inlet pipes extend into the cavity inside the main body. A connection pipe is arranged on the side of the connection seat away from the inlet pipes. A fixing pipe is fixedly installed inside the connection pipe on the side of the connection seat away from the inlet pipes. The connection seat is connected with a drainage pipe through a fixing component. However, when connecting the drainage pipe and the joint, there is a lack of a fixing mechanism. The drainage pipe is directly inserted into the joint, and the connection is unstable and easy to fall off, which is inconvenient to use.

[0004] Currently, when most negative pressure drainers are in use, when the user places the tank body inside the support frame and then starts the device, the accumulated fluid can be absorbed. However, when the suction pipe at one end of the connector sucks liquid in different areas during the use of the device, cross-infection is likely to occur, and the connector needs to be replaced. However, the connector generally uses a threaded connection, making it difficult to replace quickly. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the drawbacks in the existing technology that when the suction pipe at one end of the connector sucks liquid in different areas, cross-infection is likely to occur, and the connector needs to be replaced. However, the connector generally uses a threaded connection, making it difficult to replace quickly, and to propose a negative pressure drainer.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a negative pressure drainer, which includes a support column and a replacement device. A support frame is arranged on the surface of the support column. The side of the support column is fixedly connected with a drainage main body. A tank body is arranged inside the support frame. A conduit is fixedly connected to the upper surface of the tank body. The replacement device is arranged at one end of the conduit. The replacement device includes a groove and a connector. The connector is arranged at one end of the conduit. The groove is opened on the side of the conduit. A connection block is fixedly connected to the side of the connector. A rotating plate is rotatably connected to the inner wall of the connection block. One end of the rotating plate is clamped with the inner wall of the groove.

[0007] Preferably, a second spring is fixedly connected to the surface of the rotating plate, and one end of the second spring away from the rotating plate is fixedly connected to the surface of the connecting head. By providing the rotating plate, the connecting head and the conduit can be restricted, reducing the situation that the connecting head is easily detached from the conduit during the use of the device, resulting in the detachment of the connecting head from the conduit.

[0008] Preferably, a resisting ring is slidably connected to the surface of the connecting head, and the resisting ring abuts against the surface of the rotating plate. The provision of the resisting ring facilitates the restriction of the rotating plate.

[0009] Preferably, a first spring is fixedly connected to the surface of the resisting ring, and one end of the first spring away from the resisting ring is fixedly connected to the surface of the connecting head. The provision of the first spring facilitates the application of elastic force to the resisting ring.

[0010] Preferably, an adjusting device is provided on the surface of the support column. The adjusting device includes a rotating block and a pressing groove. The pressing groove is opened on the surface of the support column. The rotating block is rotatably connected to the surface of the support column. The side surface of the rotating block is fixedly connected to the side surface of the support frame. A plurality of equally spaced clamping grooves are opened on the lower surface of the rotating block. By providing the rotating block, it is convenient to connect and rotate the support frame, reducing the situation that the support frame is difficult to rotate during the use of the device.

[0011] Preferably, a clamping ball is slidably connected to the inner wall of the pressing groove, and one end of the clamping ball is clamped with the inner wall of the clamping groove. The provision of the clamping ball facilitates the restriction of the rotating block.

[0012] Preferably, one end of the clamping ball is fixedly connected to a third spring, and one end of the third spring away from the clamping ball is fixedly connected to the inner wall of the pressing groove. The provision of the third spring facilitates the application of elastic force to the clamping ball.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, when using the device, when the user places the tank body inside the support frame and then starts the device, the accumulated liquid can be absorbed. When the device needs to be used, the user presses the resisting ring. Then, the movement of the resisting ring drives the first spring to displace and deform to generate elastic force. Then, the resisting ring moves away from one end of the rotating plate. Then, the rotating plate is pressed to drive the second spring to displace and deform to generate elastic force. Then, the rotating plate disengages from the inside of the groove. Then, the connecting head loses its restraint. Then, the connecting head is pulled to disengage from the surface of the conduit for replacement. By providing the replacement device, the connecting head can be effectively replaced, playing a role in replacing the connecting head, reducing the situation that cross-infection is likely to occur when the suction pipe at one end of the connecting head sucks liquid from different areas during the use of the device, and the connecting head needs to be replaced. However, the connecting head is generally connected by threads and is difficult to replace quickly, improving the practicability of the device.

[0015] 2. In the present utility model, by providing an adjustment device, when the device needs to be used, the user rotates the support frame. Subsequently, the rotation of the support frame drives the rotating block to rotate on the surface of the support column. When the rotating block rotates, it pushes the clamping ball to move. When the clamping ball moves, it drives the third spring to displace and deform to generate elastic force, and then limits the rotating block. By providing the adjustment device, the rotating block is effectively restricted and adjusted, which plays a role in restricting the support frame, reducing the situation that the support frame rotates randomly during the use of the device, causing the tank body to rotate randomly and winding the conduit, and improving the practicability of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Please refer to Figures 1-5 , the present utility model provides a technical solution: a negative pressure drainage device, including a support column 1 and a replacement device 6. A support frame 3 is arranged on the surface of the support column 1, a drainage main body 2 is fixedly connected to the side surface of the support column 1, a tank body 4 is arranged inside the support frame 3, and a conduit 5 is fixedly connected to the upper surface of the tank body 4.

[0023] Next, the specific settings and functions of its replacement device 6 and adjustment device 7 will be specifically described.

[0024] In this embodiment: The replacement device 6 is arranged at one end of the conduit 5. The replacement device 6 includes a groove 61 and a connector 65. The connector 65 is arranged at one end of the conduit 5. The groove 61 is opened on the side surface of the conduit 5. A connecting block 62 is fixedly connected to the side surface of the connector 65. A rotating plate 66 is rotatably connected to the inner wall of the connecting block 62. One end of the rotating plate 66 is clamped with the inner wall of the groove 61.

[0025] Specifically, a second spring 67 is fixedly connected to the surface of the rotating plate 66. One end of the second spring 67 away from the rotating plate 66 is fixedly connected to the surface of the connector 65.

[0026] In this embodiment: By setting the rotating plate 66, the connection between the connector 65 and the conduit 5 can be restricted, reducing the situation that the connector 65 is likely to be separated from the conduit 5 during the use of the device.

[0027] Specifically, a resisting ring 63 is slidably connected to the surface of the connector 65. The resisting ring 63 abuts against the surface of the rotating plate 66. The setting of the resisting ring 63 facilitates the restriction of the rotating plate 66.

[0028] Specifically, a first spring 64 is fixedly connected to the surface of the resisting ring 63. One end of the first spring 64 away from the resisting ring 63 is fixedly connected to the surface of the connector 65. The setting of the first spring 64 facilitates applying an elastic force to the resisting ring 63.

[0029] In this embodiment: An adjusting device 7 is arranged on the surface of the support column. The adjusting device 7 includes a rotating block 75 and a pressing groove 71. The pressing groove 71 is opened on the surface of the support column. The rotating block 75 is rotatably connected to the surface of the support column 1. The side surface of the rotating block 75 is fixedly connected to the side surface of the support frame 3. A plurality of equally spaced clamping grooves 72 are opened on the lower surface of the rotating block 75.

[0030] In this embodiment: By setting the rotating block 75, it is convenient to connect and rotate the support frame 3, reducing the situation that the support frame 3 is difficult to rotate during the use of the device.

[0031] Specifically, a clamping ball 73 is slidably connected to the inner wall of the pressing groove 71. One end of the clamping ball 73 is clamped with the inner wall of the clamping groove 72. The setting of the clamping ball 73 facilitates the restriction of the rotating block 75.

[0032] Specifically, one end of the clamping ball 73 is fixedly connected to a third spring 74. One end of the third spring 74 away from the clamping ball 73 is fixedly connected to the inner wall of the pressing groove 71. The setting of the third spring 74 facilitates applying an elastic force to the clamping ball 73.

[0033] Working principle: When using the device, when the user places the tank body 4 inside the support frame 3, the device can be started immediately to absorb the liquid accumulation. When the device needs to be used, the user presses the abutting ring 63. Then, the movement of the abutting ring 63 drives the displacement and deformation of the first spring 64 to generate elastic force. Then, the abutting ring 63 moves away from one end of the rotating plate 66. Then, pressing the rotating plate 66 drives the displacement and deformation of the second spring 67 to generate elastic force. Then, the rotating plate 66 disengages from the inside of the groove 61. Then, the connector 65 loses its restraint. Then, pulling the connector 65 disengages it from the surface of the conduit 5 for replacement. By setting the replacement device 6, the connector 65 can be effectively replaced, which plays a role in replacing the connector 65, reduces the cross-infection that is likely to occur when the suction pipe at one end of the connector 65 sucks liquid from different areas during the use of the device, and requires the replacement of the connector 65. However, the connector 65 is generally connected by threads and is difficult to replace quickly, thus improving the practicality of the device.

[0034] When the device needs to be used, the user rotates the support frame 3. Then, the rotation of the support frame 3 drives the rotating block 75 to rotate on the surface of the support column. When the rotating block 75 rotates, it presses the ball 73 to move. When the ball 73 moves, it drives the displacement and deformation of the third spring 74 to generate elastic force. Then, the rotating block 75 is limited. By setting the adjustment device 7, the rotating block 75 can be effectively restricted and adjusted, which plays a role in restricting the support frame 3, reduces the situation that the support frame 3 is likely to rotate randomly during the use of the device, causing the tank body 4 to rotate randomly and winding the conduit 5, thus improving the practicality of the device.
