[0001] The invention relates to the technical field of sealing detection equipment, and in particular to a drainage tube sealing detection device and a detection method thereof. Background Art

[0002] Drainage tubes are used for clinical surgical drainage. They are a kind of medical device that guides the pus, blood, and liquid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some are used for urinary catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract, bile duct, etc. The purpose of surgical drainage is to guide the pus, blood, and liquid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and affect wound healing. It is generally made of materials such as silicone rubber or polyurethane. High-pressure gas is usually sent into the drainage tube to complete the sealing detection and processing of the drainage tube by existing equipment.

[0003] Among them, when testing the drainage tube, electronic instruments are mostly used for testing. Due to the squeezing of the high-pressure gas inside the equipment, the pressure on the electronic instruments increases simultaneously. This will cause the testing equipment to be easily damaged after long-term use, affecting the detection efficiency. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a drainage tube sealing detection device, including a mounting mechanism, the mounting mechanism also includes a base, the top of the base is fixedly connected to a support frame, the inner wall of the support frame is fixedly connected to a fixed tube, the inner wall of the fixed tube is fixedly connected to a fixed frame, and the inner wall of the fixed frame is fixedly connected to an installation box;

[0005] The clamping mechanism includes a rotating column rotatably connected to the inner wall of the through hole of the installation box, a gear column is fixedly connected to the side wall of the rotating column, and an end of the rotating column away from the gear column is fixedly connected to the hydraulic box;

[0006] The protection mechanism comprises a plurality of telescopic rods fixedly connected to the outer wall of the fixed tube, one end of the telescopic rod away from the fixed tube is fixedly connected to the second gear rod, and the other end of the second gear rod is fixedly connected to the extrusion arc plate.

[0007] Preferably, the mounting mechanism also includes an electric telescopic rod fixedly connected to the inner wall of the fixed tube, the end of the electric telescopic rod away from the fixed tube is fixedly connected to a piston plate, the side wall of the piston plate is slidably connected to the inner wall of the fixed tube, and the side wall of the piston plate is fixedly connected to a liquid containing tube.

[0008] Preferably, the installation mechanism also includes an air pressure expansion tube connected to the side wall of the piston plate, the end of the air pressure expansion tube away from the piston plate is fixedly connected to the fixed plate, the side wall of the fixed plate is fixedly connected to a pulling spring, the end of the pulling spring away from the fixed plate is fixedly connected to the side wall of the piston plate, and the inner wall of the fixed tube is fixedly connected to an alarm. By utilizing the characteristic that high-pressure gas will generate an outward expansion force, an air pressure expansion tube and an alarm are arranged inside the device. When using the device, the drainage tube to be detected is installed between the outer wall of the rubber sealing ring 1 and the inner wall of the rubber sealing ring 2 to form a Figure 2 In the state shown, after ensuring that both ends of the drainage tube are in a sealed state, the inner wall of the drainage tube, the fixed tube and the side wall of the piston plate will form a closed environment. When the power of the electric telescopic rod is turned on, the electric telescopic rod will generate an extension force and push the piston plate to slide along the inner wall of the fixed tube. As the piston plate slides, the air inside the closed space is squeezed and generates an outward pushing force, which will act on the inside of the pneumatic telescopic tube, causing the pneumatic telescopic tube to expand outward and drive the fixed plate to move synchronously. In this process, the electric telescopic rod pushes the piston plate to move outward, and the high pressure on the side wall of the piston plate The gas pushes the fixed plate to move inward. Under the restrictions of two moving directions, the position of the fixed plate will not change significantly, and there will be a distance from the side of the alarm. At this time, if the sealing of the drainage tube is good, the position of the fixed plate will remain unchanged. If the sealing of the drainage tube is poor, as the gas inside the drainage tube flows out, the air pressure inside the enclosed space decreases, and the fixed plate is pulled by the pulling spring to contact the alarm, and the alarm sounds an alarm. Through the application of the above components, the force generated by the high-pressure gas will be prevented from directly acting on the instrument, causing damage to the instrument.

[0009] Preferably, the clamping mechanism also includes a rotating plate fixedly connected to the side wall of the rotating column, a plurality of hydraulic telescopic rods are connected through the side wall of the hydraulic box, and one end of the liquid containing tube away from the piston plate is connected through the side wall of the hydraulic box.

[0010] Preferably, the clamping mechanism also includes a sliding gear rod slidably connected to the side wall of the installation box, an L-shaped rod is fixedly connected to the side wall of the sliding gear rod, an end of the L-shaped rod away from the sliding gear rod is fixedly connected to an outer support plate, a rubber sealing ring is sleeved on the outer wall of the outer support plate, and a gear rod is provided at the end of the sliding gear rod away from the gear column. The side wall of the sliding gear rod is meshingly connected with the side wall of the gear column. Utilizing the characteristic that the above-mentioned piston plate slides along the inner wall of the fixed tube, a liquid containing tube is provided inside the device. When the piston plate moves outward, the distance between the piston plate and the fixed frame is reduced, and the liquid containing tube in the middle is squeezed to The liquid is transmitted to the hydraulic telescopic rod through the hydraulic box, and the extension of the hydraulic telescopic rod will drive the rotating plate to rotate with the rotating column as the center. At the same time, the gear column drives the outer support plate to move outward through the sliding gear rod and the L-shaped rod, and clamps and restricts the inner wall of the drainage tube on the outer wall of the rubber sealing ring. At this time, as the sliding gear rod moves outward, it will drive gear rod 1 to move outward synchronously. Gear rod 1 drives gear rod 2 and the extrusion arc plate to move inward through the gear, and clamps the inner wall of the drainage tube. Through the application of the above components, the clamping area of ​​the drainage tube is increased, and the deformation of the outer wall of the drainage tube under high pressure environment is reduced.

[0011] Preferably, the protection mechanism also includes a plurality of limit brackets fixedly connected to the side wall of the fixed tube, and the plurality of limit brackets are rotatably connected to a gear at one end away from the fixed tube, and the side wall of the gear is meshingly connected to the side wall of gear rod 2, and the side wall of the gear is meshingly connected to the side wall of gear rod 1. The characteristic of the gear column controlling the outward movement of multiple sliding gear rods is utilized. When the equipment is in use, the rotating plate rotates around the rotating column due to the push of the hydraulic telescopic rod, and the rotating column drives the multiple sliding gear rods to move outward at the same time through the gear column, and the sliding gear rod drives the corresponding extrusion arc plates to shrink inward through the gears. The characteristic of the multiple extrusion arc plates and the outer support plate exerting pressure on the drainage tube at the same time is utilized to ensure that the pressure generated between the multiple extrusion arc plates and the outer support plate is equal during the actual application of the equipment, so as to avoid deformation of the drainage tube caused by excessive pressure in some areas.

[0012] Preferably, the protection mechanism also includes a rubber sealing ring 2 fixedly connected to the side wall of the extrusion arc plate, a plurality of rotating rods 1 are rotatably connected to the outer wall of the extrusion arc plate, a rotating rod 2 is rotatably connected to the side wall of the extrusion arc plate, and the end of the rotating rod 1 away from the extrusion arc plate is rotatably connected to the inner wall of the rotating rod 2. Utilizing the characteristic that multiple extrusion arc plates expand or contract during the above-mentioned use process, a rotating rod 1 is arranged inside the device, wherein multiple sliding gear rods will be synchronously displaced under the influence of the gear column. During this process, the sliding gear rod will drive the corresponding extrusion arc plates to contract synchronously. At this time, the distance between the multiple extrusion arc plates is reduced, and the rotating rod 1 and the rotating rod 2 rotatably connected to the outer wall of the extrusion arc plate will be synchronously displaced, and during the displacement process, the connection angle of the rotating rod 1 and the rotating rod 2 will be reduced, and the connection position will exceed the outermost position of the extrusion arc plate. Through the application of the above-mentioned components, it is avoided that when the drainage tube is in use, the connection position causes the tube to be tightened due to high pressure, resulting in the angle of the turning position being too small, causing the drainage tube to bend, and causing damage to the outer wall of the drainage tube.

[0013] A detection method of a drainage tube sealing detection device comprises the following steps:

[0014] S1: When in use, install the drainage tube to be tested between the outer wall of the rubber sealing ring 1 and the inner wall of the rubber sealing ring 2, ensuring that both ends of the drainage tube are in a sealed state;

[0015] S2: At this time, the inner wall of the drainage tube, the fixed tube and the side wall of the piston plate form a closed environment. When the power of the electric telescopic rod is turned on, the electric telescopic rod generates an extension force and pushes the piston plate to slide along the inner wall of the fixed tube;

[0016] S3: As the piston plate slides, the air inside the enclosed space is squeezed and generates an outward pushing force, which acts on the inside of the pneumatic expansion tube, causing the pneumatic expansion tube to expand outward and drive the fixed plate to move synchronously.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention utilizes the characteristic that high pressure gas will generate an outward expansion force. A gas pressure expansion tube and an alarm are arranged inside the device. When the device is used, the drainage tube to be detected is installed between the outer wall of the rubber sealing ring 1 and the inner wall of the rubber sealing ring 2 to form a Figure 2In the state shown, after ensuring that both ends of the drainage tube are in a sealed state, the inner wall of the drainage tube, the fixed tube and the side wall of the piston plate will form a closed environment. When the power of the electric telescopic rod is turned on, the electric telescopic rod will generate an extension force and push the piston plate to slide along the inner wall of the fixed tube. As the piston plate slides, the air inside the closed space is squeezed and generates an outward pushing force, which will act on the inside of the pneumatic telescopic tube, causing the pneumatic telescopic tube to expand outward and drive the fixed plate to move synchronously. In this process, the electric telescopic rod pushes the piston plate to move outward, and the high pressure on the side wall of the piston plate The gas pushes the fixed plate to move inward. Under the restrictions of two moving directions, the position of the fixed plate will not change significantly, and there will be a distance from the side of the alarm. At this time, if the sealing of the drainage tube is good, the position of the fixed plate will remain unchanged. If the sealing of the drainage tube is poor, as the gas inside the drainage tube flows out, the air pressure inside the enclosed space decreases, and the fixed plate is pulled by the pulling spring to contact the alarm, and the alarm sounds an alarm. Through the application of the above components, the force generated by the high-pressure gas will be prevented from directly acting on the instrument, causing damage to the instrument.

[0019] (2) The present invention utilizes the characteristic that the piston plate slides along the inner wall of the fixed tube, and a liquid containing tube is arranged inside the device. When the piston plate moves outward, the distance between the piston plate and the fixed frame is reduced, and the liquid containing tube in the middle is squeezed to transmit the internal liquid to the hydraulic telescopic rod through the hydraulic box. The extension of the hydraulic telescopic rod will drive the rotating plate to rotate around the rotating column. At the same time, the gear column drives the outer support plate to move outward through the sliding gear rod and the L-shaped rod, and clamps and restricts the inner wall of the drainage tube on the outer wall of the rubber sealing ring. At this time, as the sliding gear rod moves outward, it will drive gear rod 1 to move outward synchronously. Gear rod 1 drives gear rod 2 and the extrusion arc plate to move inward through the gear, and clamps the inner wall of the drainage tube. Through the application of the above components, the clamping area of ​​the drainage tube is increased, and the deformation of the outer wall of the drainage tube under high pressure environment is reduced.

[0020] (3) The present invention utilizes the characteristic of the gear column controlling the outward movement of multiple sliding gear rods. When the equipment is in use, the rotating plate rotates around the rotating column due to the push of the hydraulic telescopic rod, and the rotating column drives multiple sliding gear rods to move outward at the same time through the gear column, and the sliding gear rods drive the corresponding extrusion arc plates to shrink inward through the gears. The characteristic of the multiple extrusion arc plates and the outer support plates exerting pressure on the drainage tube at the same time is utilized to ensure that the pressure generated between the multiple extrusion arc plates and the outer support plates is equal during the actual application of the equipment, thereby avoiding deformation of the drainage tube caused by excessive pressure in some areas.

[0021] (4) The present invention utilizes the characteristic that multiple extrusion arc plates expand or contract during the above-mentioned use process, and is provided with a rotating rod 1 inside the device, wherein multiple sliding gear rods are affected by the gear column and will be displaced synchronously. During this process, the sliding gear rod will drive the corresponding extrusion arc plates to contract synchronously. At this time, the distance between the multiple extrusion arc plates is reduced, and the rotating rod 1 and the rotating rod 2 which are rotatably connected to the outer wall of the extrusion arc plate will be displaced synchronously. In the process of displacement, the connection angle between the rotating rod 1 and the rotating rod 2 will be reduced, and the connection position will exceed the outermost position of the extrusion arc plate. Through the application of the above-mentioned components, it is avoided that when the drainage tube is in use, the connection position of the drainage tube is tightened due to high pressure, resulting in too small an angle at the turning position, causing the drainage tube to bend, and causing damage to the outer wall of the drainage tube.

[0040] The mounting mechanism 1 further comprises an air pressure expansion tube 18 which is connected to the side wall of the piston plate 17. The end of the air pressure expansion tube 18 which is away from the piston plate 17 is fixedly connected to a fixing plate 111. A pulling spring 19 is fixedly connected to the side wall of the fixing plate 111. The end of the pulling spring 19 which is away from the fixing plate 111 is fixedly connected to the side wall of the piston plate 17. An alarm 112 is fixedly connected to the inner wall of the fixing tube 13. The air pressure expansion tube 18 and the alarm 112 are arranged inside the device by utilizing the characteristic that high pressure gas will generate an outward expansion force. When using the device, the drainage tube to be detected is installed between the outer wall of the rubber sealing ring 210 and the inner wall of the rubber sealing ring 237 to form a structure as shown in FIG. Figure 2 In the state shown, after ensuring that both ends of the drainage tube are in a sealed state, the inner wall of the drainage tube, the fixed tube 13 and the side wall of the piston plate 17 will form a closed environment.

Through the application of the above-mentioned components, the force generated by the high-pressure gas will be prevented from directly acting on the instrument, causing damage to the instrument.

[0041] For example 2, please refer to Figure 4 - Figure 8 The present invention is a drainage tube sealing detection device. On the basis of the first embodiment, the clamping mechanism 2 also includes a rotating plate 24 fixedly connected to the side wall of the rotating column 21, and a plurality of hydraulic telescopic rods 25 are connected through the side wall of the hydraulic box 23. The end of the liquid containing tube 110 away from the piston plate 17 is connected through the side wall of the hydraulic box 23.

[0042] The clamping mechanism 2 also includes a sliding gear rod 26 slidably connected to the side wall of the installation box 15, an L-shaped rod 28 is fixedly connected to the side wall of the sliding gear rod 26, an end of the L-shaped rod 28 away from the sliding gear rod 26 is fixedly connected to an outer support plate 29, a rubber sealing ring 210 is sleeved on the outer wall of the outer support plate 29, and a gear rod 211 is provided at the end of the sliding gear rod 26 away from the gear column 22. The side wall of the sliding gear rod 26 is meshed and connected with the side wall of the gear column 22. Utilizing the characteristic that the piston plate 17 slides along the inner wall of the fixed tube 13, a liquid containing tube 110 is arranged inside the device. When the piston plate 17 moves outward, the distance between the piston plate 17 and the fixed frame 14 is reduced, and the liquid containing tube 110 in the middle is affected. The internal liquid is extruded and transmitted to the hydraulic telescopic rod 25 through the hydraulic box 23, and the extension of the hydraulic telescopic rod 25 will drive the rotating plate 24 to rotate around the rotating column 21. At the same time, the gear column 22 drives the outer support plate 29 to move outward through the sliding gear rod 26 and the L-shaped rod 28, and clamps and restricts the inner wall of the drainage tube on the outer wall of the rubber sealing ring 210. At this time, as the sliding gear rod 26 moves outward, it will drive the gear rod 1 211 to move outward synchronously. The gear rod 1 211 drives the gear rod 2 32 and the extrusion arc plate 33 to move inward through the gear 36, and clamps the inner wall of the drainage tube. Through the application of the above components, the clamping area of ​​the drainage tube is increased, and the deformation of the outer wall of the drainage tube under high pressure environment is reduced.

[0043] The protection mechanism 3 also includes a plurality of limit brackets 35 fixedly connected to the side wall of the fixed tube 13. The plurality of limit brackets 35 are rotatably connected to one end away from the fixed tube 13 with a gear 36. The side wall of the gear 36 is meshingly connected to the side wall of the gear rod 2 32. The side wall of the gear 36 is meshingly connected to the side wall of the gear rod 1 211. The gear column 22 is used to control the outward movement of the plurality of sliding gear rods 26. When the equipment is in use, the rotating plate 24 rotates around the rotating column 21 as the center due to the push of the hydraulic telescopic rod 25, and the rotating column 21 drives the plurality of sliding gear rods 26 to move outward at the same time through the gear column 22, and the sliding gear rods 26 drive the corresponding extrusion arc plates 33 to retract inward through the gear 36. The plurality of extrusion arc plates 33 and the outer support plate 29 simultaneously exert pressure on the drainage tube. The pressure generated between the plurality of extrusion arc plates 33 and the outer support plate 29 is equal during the actual application of the equipment, so as to avoid deformation of the drainage tube caused by excessive pressure in some areas.

[0044] The protection mechanism 3 also includes a rubber sealing ring 2 37 fixedly connected to the side wall of the extrusion arc plate 33, a plurality of rotating rods 38 are rotatably connected to the outer wall of the extrusion arc plate 33, a rotating rod 2 39 is rotatably connected to the side wall of the extrusion arc plate 33, and one end of the rotating rod 1 38 away from the extrusion arc plate 33 is rotatably connected to the inner wall of the rotating rod 2 39. In the above-mentioned use process, the multiple extrusion arc plates 33 generate expansion or contraction characteristics, and a rotating rod 1 38 is arranged inside the device, wherein the multiple sliding gear rods 26 are affected by the gear column 22 and will synchronously generate displacement. In this process, the sliding gear rod 2 6 will drive the corresponding extrusion arc plates 33 to shrink synchronously. At this time, the distance between the multiple extrusion arc plates 33 will be reduced, and the rotating rod 1 38 and the rotating rod 2 39 that are rotatably connected to the outer wall of the extrusion arc plate 33 will be displaced synchronously. In the process of displacement, the connection angle of the rotating rod 1 38 and the rotating rod 2 39 will be reduced, and the connection position will exceed the outermost position of the extrusion arc plate 33. Through the application of the above components, it is avoided that when the drainage tube is in use, the connection position of the drainage tube is tightened due to high pressure, resulting in too small an angle at the turning position, causing the drainage tube to bend and causing damage to the outer wall of the drainage tube.

[0045] The detection method of the detection device comprises the following steps:

[0046] S1: When in use, install the drainage tube to be tested between the outer wall of the rubber sealing ring 1 210 and the inner wall of the rubber sealing ring 2 37 to ensure that both ends of the drainage tube are in a sealed state;

[0047] S2: At this time, the inner wall of the drainage tube, the fixed tube 13 and the side wall of the piston plate 17 form a closed environment. When the power of the electric telescopic rod 16 is turned on, the electric telescopic rod 16 generates an extension force and pushes the piston plate 17 to slide along the inner wall of the fixed tube 13;

[0048] S3: As the piston plate 17 slides, the air inside the enclosed space is squeezed and generates an outward pushing force, which acts on the inside of the pneumatic telescopic tube 18, causing the pneumatic telescopic tube 18 to expand outward and drive the fixed plate 111 to move synchronously.

[0049] A specific application of this embodiment is: when using the device, the drainage tube to be detected is installed between the outer wall of the rubber sealing ring 1 210 and the inner wall of the rubber sealing ring 2 37 to form a Figure 2In the state shown, after ensuring that both ends of the drainage tube are in a sealed state, the inner wall of the drainage tube, the fixed tube 13 and the side wall of the piston plate 17 will form a closed environment. When the power of the electric telescopic rod 16 is turned on, the electric telescopic rod 16 generates an extension force and pushes the piston plate 17 to slide along the inner wall of the fixed tube 13. As the piston plate 17 slides, the air inside the closed space is squeezed and generates an outward pushing force, which will act on the inside of the pneumatic telescopic tube 18, causing the pneumatic telescopic tube 18 to expand outward and drive the fixed plate 111 to move synchronously. In this process, the electric telescopic rod 16 pushes the piston plate 17 to move outward, and the height of the side wall of the piston plate 17 The high-pressure gas pushes the fixed plate 111 to move inward. Under the restrictions of the two moving directions, the position of the fixed plate 111 will not change significantly, and there will be a distance from the side of the alarm 112. At this time, if the sealing of the drainage tube is good, the position of the fixed plate 111 will remain unchanged. If the sealing of the drainage tube is poor, as the gas inside the drainage tube flows out, the air pressure inside the enclosed space decreases. Under the pull of the pulling spring 19, the fixed plate 111 drives the fixed plate 111 to contact the alarm 112, and the alarm 112 issues a warning. Through the application of the above-mentioned components, the force generated by the high-pressure gas will be prevented from directly acting on the instrument, causing damage to the instrument.

[0050] Utilizing the characteristic that the piston plate 17 slides along the inner wall of the fixed tube 13, a liquid containing tube 110 is provided inside the device. When the piston plate 17 moves outward, the distance between the piston plate 17 and the fixed frame 14 is reduced, and the liquid containing tube 110 in the middle is squeezed to transmit the internal liquid to the hydraulic telescopic rod 25 through the hydraulic box 23. The extension of the hydraulic telescopic rod 25 will drive the rotating plate 24 to rotate around the rotating column 21. At the same time, the gear column 22 drives the outer support plate 29 to move outward through the sliding gear rod 26 and the L-shaped rod 28, and clamps and restricts the inner wall of the drainage tube on the outer wall of the rubber sealing ring 210. At this time, as the sliding gear rod 26 moves outward, it will drive the gear rod 1 211 to move outward synchronously. The gear rod 1 211 drives the gear rod 2 32 and the extrusion arc plate 33 to move inward through the gear 36, and clamps the inner wall of the drainage tube. Through the application of the above components, the clamping area of ​​the drainage tube is increased, and the deformation of the outer wall of the drainage tube under high pressure environment is reduced.

[0051] By utilizing the characteristic of the gear column 22 controlling the outward movement of the plurality of sliding gear rods 26, when the equipment is in use, the rotating plate 24 rotates around the rotating column 21 due to the push of the hydraulic telescopic rod 25, and the rotating column 21 drives the plurality of sliding gear rods 26 to move outward at the same time through the gear column 22, and the sliding gear rods 26 drive the corresponding extrusion arc plates 33 to retract inward through the gear 36. By utilizing the characteristic of the plurality of extrusion arc plates 33 and the outer support plate 29 exerting pressure on the drainage tube at the same time, it is ensured that during the actual application of the equipment, the pressure generated between the plurality of extrusion arc plates 33 and the outer support plate 29 is equal, so as to avoid deformation of the drainage tube caused by excessive pressure in some areas. By utilizing the characteristic of the plurality of extrusion arc plates 33 expanding or contracting during the above-mentioned use, A rotating rod 38 is provided inside the device, wherein a plurality of sliding gear rods 26 will be synchronously displaced under the influence of the gear column 22. During this process, the sliding gear rod 26 will drive the corresponding extrusion arc plates 33 to shrink synchronously. At this time, the distance between the plurality of extrusion arc plates 33 is reduced, and the rotating rod 38 and the rotating rod 39 rotatably connected to the outer wall of the extrusion arc plate 33 will be synchronously displaced. During the displacement process, the connection angle between the rotating rod 38 and the rotating rod 39 will be reduced, and the connection position will exceed the outermost position of the extrusion arc plate 33. Through the application of the above-mentioned components, it is avoided that when the drainage tube is in use, the connection position causes the tube to be tightened due to high pressure, resulting in too small an angle at the turning position, causing the drainage tube to bend and the outer wall of the drainage tube to be damaged.
