Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a drainage device for preventing the backflow of accumulated fluid. Background Art

[0002] Fluid drainage is a common surgical procedure that can divert fluid, pus, lymph, digestive fluid and other substances present in the lesion site out of the body through drainage tubes to facilitate diagnosis and treatment.

[0003] During the drainage of effusion, the drainage fluid may flow backwards in the drainage tube due to factors such as the change in the patient's body position, which may cause infection in severe cases. In the use of traditional anti-backflow devices, the drainage effect is poor due to the small flow rate and flow velocity, resulting in blockage. Therefore, we propose a drainage device that prevents the backflow of effusion. Utility Model Content

[0004] The utility model aims to provide a drainage device for preventing the backflow of accumulated fluid, so as to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drainage device for preventing the backflow of effusion, comprising two drainage tubes and a connecting tube fixedly installed between the two drainage tubes, two inclined rods fixedly installed on one side of the inner wall of the connecting tube, a fixing plate fixedly installed on one end of the two inclined rods, a plurality of hard film fixedly installed on one side of the fixing plate, an annular baffle fixedly installed in the inner cavity of the connecting tube, the annular baffle in contact with the hard film, and a resistance component is provided on one side of the connecting tube;

[0006] The resistance component includes a movable plate, which is slidably mounted on one side of the connecting pipe. A connecting block is fixedly mounted on one end of the movable plate located in the inner cavity of the connecting pipe, and a plurality of resistance members are fixedly mounted on one end of the connecting block. A moving component for driving the movable plate to move is provided on one side of the connecting pipe.

[0007] Preferably, the connecting tube is made of medical polyethylene material and is in a colorless and transparent cylindrical shape.

[0008] Preferably, the axial cross-section of the hard film is fan-shaped, and the hard film is made of medical silicone material.

[0009] Preferably, the abutment member is specifically an L-shaped top rod, and the number of the L-shaped top rods is consistent with the number of hard film sheets, and the positions of the multiple L-shaped top rods correspond to the positions of the multiple hard film sheets along the axial direction of the connecting tube.

[0010] Preferably, the movable assembly comprises a threaded rod, the threaded rod is movably mounted on one side of the connecting pipe, and the thread of the threaded rod passes through the movable plate.

[0011] Preferably, an adjusting knob is fixedly mounted on one end of the threaded rod away from the connecting pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the drainage device for preventing the backflow of accumulated fluid, if the negative pressure disappears or is insufficient to drive the flow of accumulated fluid during the drainage process, the hard film will be reset under the elasticity of the material itself and contact the annular baffle, so that a seal is formed in the middle of the connecting tube. At this time, the accumulated fluid in the drainage tube and the connecting tube stops flowing and will not flow back, which has the effect of preventing the backflow of accumulated fluid and improving the safety of drainage of accumulated fluid.

[0014] 2. The drainage device for preventing the backflow of accumulated fluid drives the threaded rod to move by turning the adjusting knob, thereby driving the connecting block to move toward the direction close to the fixed plate. The connecting block drives the L-shaped top rod to press against the hard film, thereby causing the hard film to tilt slightly, so that the accumulated fluid can pass through the connecting tube smoothly, and the accumulated fluid with a small flow rate and a small flow rate can be drained smoothly through the connecting tube.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] Please refer to Figures 1-3As shown, the utility model provides a drainage device for preventing the backflow of effusion, comprising two drainage tubes 1 and a connecting tube 2 fixedly installed between the two drainage tubes 1, two inclined rods 8 fixedly installed on one side of the inner wall of the connecting tube 2, a fixing plate 9 fixedly installed on one end of the two inclined rods 8, a plurality of hard film sheets 10 fixedly installed on one side of the fixing plate 9, an annular baffle 11 fixedly installed in the inner cavity of the connecting tube 2, the annular baffle 11 contacts the hard film sheets 10, and a resistance component is arranged on one side of the connecting tube 2;

[0022] The resistance component includes a movable plate 3, which is slidably installed on one side of the connecting tube 2. A connecting block 6 is fixedly installed at one end of the movable plate 3 located in the inner cavity of the connecting tube 2. A plurality of resistance members are fixedly installed at one end of the connecting block 6. A moving component for driving the movable plate 3 to move is provided on one side of the connecting tube 2.

[0023] Specifically, when the accumulated fluid passes through the connecting tube 2, the hard film 10 can be tilted, so that the accumulated fluid can smoothly pass through the connecting tube 2 and enter the right drainage tube 1. When the negative pressure disappears, the hard film 10 resets and seals, which can effectively prevent the accumulated fluid from flowing back.

[0024] The connecting tube 2 is made of medical polyethylene and is in a colorless and transparent cylindrical shape. Through the connecting tube 2, it is convenient to observe the condition of the hard film 10 in the inner cavity of the connecting tube 2 and the flow of the drainage fluid.

[0025] The axial cross section of the hard film 10 is fan-shaped, and the hard film 10 is made of medical silicone material. The hard film 10 has a certain elasticity and can play a sealing effect when the hard film 10 contacts the annular baffle 11 .

[0026] Among them: the resistance member is specifically an L-shaped top rod 7, and the number of L-shaped top rods 7 is consistent with the hard film 10, the positions of multiple L-shaped top rods 7 correspond one by one to the positions of multiple hard films 10 along the axial direction of the connecting tube 2, and each L-shaped top rod 7 can resist a hard film 10 when moving, so that the hard film 10 is inclined.

[0027] Wherein: the moving component includes a threaded rod 4, the threaded rod 4 is movably installed on one side of the connecting pipe 2, the thread of the threaded rod 4 passes through the movable plate 3, and an adjusting knob 5 is fixedly installed on the end of the threaded rod 4 away from the connecting pipe 2. By rotating the adjusting knob 5, the threaded rod 4 is driven to move, and the threaded rod 4 can drive the movable plate 3 to move.

[0028] Working principle: The utility model is a drainage device for preventing backflow of accumulated fluid. When draining the accumulated fluid, the accumulated fluid enters the connecting pipe 2 from the left drainage pipe 1. Under the action of negative pressure, the accumulated fluid can push the hard film 10 to tilt to the side away from the annular baffle 11, so as to pass through between the outside of the fixing plate 9 and the inner wall of the connecting pipe 2 and finally enter the right drainage pipe 1, thus completing the work of draining the accumulated fluid. If the negative pressure disappears or is insufficient to drive the flow of the accumulated fluid, the hard film 10 resets under the elasticity of the material itself, sealing the middle part of the connecting pipe 2. At this time, the accumulated fluid in the drainage pipe 1 and the connecting pipe 2 stops flowing and will not flow back;

[0029] If the flow rate or flow volume of the accumulated fluid is too small to drive the hard film 10 to tilt, the adjusting knob 5 can be rotated to drive the threaded rod 4 to move, thereby driving the movable plate 3 to move. The movable plate 3 drives the connecting block 6 to move towards the fixing plate 9. The connecting block 6 drives the L-shaped ejector rod 7 to abut against the hard film 10, so that the hard film 10 tilts slightly, enabling the accumulated fluid to pass through the connecting pipe 2 smoothly.

[0030] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
