Description

Technical Field

[0001] This application relates to the field of suction catheters, and more specifically, to a suction catheter flushing device. Background Technology

[0002] In critically ill patients, sputum often cannot be expelled spontaneously, requiring the use of a suction device to remove it, and the suction catheter tubing must be flushed after use. Existing suction catheter flushing devices mainly consist of a syringe and saline solution. During operation, the saline solution must first be drawn out using the syringe before connecting the syringe to the suction catheter tubing to complete the procedure.

[0003] The announcement number CN218591353U discloses a suction tube flushing device. After the motor is working, it drives the lead screw to rotate. The lead screw is connected by a first internal threaded cylinder, a second internal threaded cylinder, a screw, and an L-shaped connecting column. The piston can be raised and lowered by limiting the sliding of the piston in the injection tube. The raising and lowering of the piston can drive the piston to slide in the injection tube. This allows the injection tube to draw saline into the tube when the piston rises and to discharge the saline at a uniform speed when the piston falls. This achieves a uniform discharge speed and avoids uneven discharge speed or interruption caused by manual squeezing.

[0004] However, the above solution has some drawbacks: during the flushing process, if the saline solution runs out before the suction catheter is completely flushed, the suction catheter needs to be removed and refilled with saline solution before it can be used again. This not only makes the operation cumbersome but also inefficient. Utility Model Content

[0005] To overcome the above deficiencies, this application provides a suction catheter flushing device, which aims to improve the problems mentioned in the background art.

[0006] This application provides a suction catheter flushing device including a flushing component and an adjustment component.

[0007] The flushing assembly includes a base plate, a drive unit, a sliding rod, a piston, an injection tube, a suction tube, a flushing tube, and a one-way valve. The drive unit is located on the top of the base plate, the sliding rod is fixedly connected to the drive unit, the piston is located at the end of the sliding rod, the injection tube slides through the base plate, and the piston and the inner cavity of the injection tube are adapted and fitted together. The suction tube and the flushing tube are both connected to the bottom of the injection tube, and the one-way valve is connected to both the suction tube and the flushing tube.

[0008] The adjustment assembly includes an elastic element, a sliding ring, and a positioning rod. The elastic element is disposed on the outside of the injection tube, the sliding ring is slidably sleeved on the injection tube and the elastic element, and the positioning rod is disposed at the bottom of the sliding ring and is engaged with the base plate.

[0009] In one specific implementation, the driving component includes a support plate, a support rod, a top plate, a threaded rod, a motor, and a movable block. The support plate is disposed on the top of the base plate, the support rod is disposed on the top of the support plate, the top plate is disposed on the top of the support rod, the threaded rod is rotatably disposed between the support plate and the top plate, the motor is disposed inside the support plate and is drivenly connected to the threaded rod, the movable block is threadedly sleeved on the threaded rod, and the sliding rod is fixedly connected to the movable block.

[0010] In the above implementation process, a support plate, support rod, top plate, threaded rod, motor, and moving block are set up. The motor is started to drive the threaded rod to rotate. The threaded rod drives the moving block to move through the thread transmission principle. The moving block drives the sliding rod and piston to move, so as to achieve the injection purpose.

[0011] In one specific implementation, the movable block is provided with a guide block, which is slidably sleeved on the support rod.

[0012] In the above implementation process, a guide block is set to guide the moving block to move stably and linearly along the support rod.

[0013] In one specific implementation, the flow directions of one of the check valves connected to the suction pipe and the other check valve connected to the flushing pipe are opposite.

[0014] In the above process, during aspiration, the aspiration tube draws physiological saline into the injection tube, while the rinsing tube is blocked by its one-way valve. During injection, the physiological saline in the injection tube is injected from the rinsing tube into the suction tube for rinsing, while the aspiration tube is blocked by its one-way valve. This process of rinsing the suction tube is repeated.

[0015] In one specific implementation, the elastic element includes a grooved plate, a vertical rod, and a spring. The grooved plate is fixedly connected to the injection tube, the vertical rod is disposed inside the grooved plate, the spring is sleeved on the vertical rod, and the sliding ring is slidably sleeved on the vertical rod.

[0016] In the above implementation process, by setting up a groove plate, a vertical rod and a spring, the sliding ring can be slid up and rotate, which will also drive the injection tube to rotate, adjust the orientation of the suction tube and the rinsing tube, adapt to the adjustment of different patients or suction tube positions, and improve practicality.

[0017] In one specific implementation, the sliding ring has a through hole, and the upright is adapted to the through hole.

[0018] In one specific implementation, the base plate has multiple positioning grooves, and the positioning rod is adapted to the positioning grooves.

[0019] In the above implementation process, by opening multiple positioning slots, after rotating and adjusting the angle of the injection tube, the positioning rod falls into the corresponding positioning slot, thus restricting the rotation of the injection tube.

[0020] In one specific implementation, the injection tube is a transparent tube, and both the piston and the bottom of the injection tube are conical.

[0021] In the above implementation process, the transparent design facilitates observation of the injection process, and the conical bottom design helps to fully inject the liquid.

[0022] Beneficial effects: This application provides a suction catheter flushing device. By setting up a base plate, a driving component, a sliding rod, a piston, an injection tube, a suction tube, a flushing tube, and a one-way valve, the device uses a one-way valve to control the unidirectional flow of liquid in the suction tube and the flushing tube. This avoids the need to disassemble the suction catheter, repeatedly aspirate and replenish saline for flushing, reducing steps and improving efficiency. By setting up an elastic component, a sliding ring, and a positioning rod, the sliding ring can be rotated to drive the injection tube to rotate and adjust the position of the suction tube and the flushing tube, adapting to different patients or suction catheter positions, thus improving practicality.

Detailed Implementation

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] Please see Figures 1-5 This application provides a suction catheter irrigation device including an irrigation component 100 and an adjustment component 200.

[0032] Please see Figure 1 , 2 3. The flushing assembly 100 includes a base plate 110, a drive component 120, a sliding rod 130, a piston 140, an injection tube 150, a suction tube 160, a flushing tube 170, and a one-way valve 180. The drive component 120 is disposed on the top of the base plate 110, the sliding rod 130 is fixedly connected to the drive component 120, the piston 140 is disposed at the end of the sliding rod 130, the injection tube 150 slides through the base plate 110, and the inner cavities of the piston 140 and the injection tube 150 are adapted to fit together. The suction tube 160 and the flushing tube 170 are both connected and disposed at the bottom of the injection tube 150, and the suction tube 160 and the flushing tube 170 are both connected and disposed with the one-way valve 180.

[0033] The driving component 120 includes a support plate 121, a support rod 122, a top plate 123, a threaded rod 124, a motor 125, and a moving block 126. The support plate 121 is located on top of the base plate 110, the support rod 122 is located on top of the support plate 121, the top plate 123 is located at the top of the support rod 122, the threaded rod 124 is rotatably disposed between the support plate 121 and the top plate 123, the motor 125 is disposed inside the support plate 121 and is drivenly connected to the threaded rod 124, and the moving block 126 is threadedly sleeved onto the threaded rod 124. The threaded rod 124 and the sliding rod 130 are fixedly connected to the moving block 126. By setting up a support plate 121, a support rod 122, a top plate 123, a threaded rod 124, a motor 125, and a moving block 126, the motor 125 is started to drive the threaded rod 124 to rotate. The threaded rod 124 drives the moving block 126 to move through the thread transmission principle. The moving block 126 drives the sliding rod 130 and the piston 140 to move, so as to achieve the injection purpose. The forward and reverse rotation of the motor 125 is existing technology. The specific structure and control principle will not be described in detail here.

[0034] Specifically, the movable block 126 is provided with a guide block 1261, which is slidably sleeved on the support rod 122. By providing the guide block 1261, the movable block 126 is guided to move stably and linearly along the support rod 122.

[0035] It should be noted that the flow directions of the one-way valve 180 connected to the suction tube 160 and the other one-way valve 180 connected to the flushing tube 170 are opposite. When suctioning, the suction tube 160 draws physiological saline into the injection tube 150, while the flushing tube 170 is blocked by its one-way valve 180. When injection molding, the physiological saline in the injection tube 150 is injected into the suction tube from the flushing tube 170 to flush it, while the suction tube 160 is blocked by its one-way valve 180. The suction tube is flushed repeatedly in this way.

[0036] Please see Figure 1 , 3 4 and 5, the adjustment assembly 200 includes an elastic element 210, a sliding ring 220 and a positioning rod 230. The elastic element 210 is disposed on the outside of the injection tube 150. The sliding ring 220 is slidably sleeved on the injection tube 150 and the elastic element 210. The positioning rod 230 is disposed at the bottom of the sliding ring 220 and is snapped into the base plate 110.

[0037] The elastic element 210 includes a groove plate 211, a vertical rod 212, and a spring 213. The groove plate 211 is fixedly connected to the injection tube 150, the vertical rod 212 is disposed inside the groove plate 211, the spring 213 is sleeved on the vertical rod 212, and the sliding ring 220 is slidably sleeved on the vertical rod 212. By setting the groove plate 211, the vertical rod 212, and the spring 213, the sliding ring 220 can be slid upward and then rotate. The injection tube 150 is provided with a limiting ring that abuts against the bottom plate 110 when it moves upward, limiting the upward movement of the injection tube 150. At the same time, it will also drive the injection tube 150 to rotate, adjusting the orientation of the suction tube 160 and the rinsing tube 170, adapting to the adjustment of different patients or suction tube positions, and improving practicality.

[0038] In one specific implementation, the sliding ring 220 has a through hole 221, and the upright 212 is adapted to the through hole 221.

[0039] The base plate 110 has multiple positioning slots 111. The positioning rod 230 is adapted to the positioning slots 111. By opening multiple positioning slots 111, after the angle of the injection tube 150 is adjusted by rotation, the positioning rod 230 falls into the corresponding positioning slot 111, thus restricting the rotation of the injection tube 150.

[0040] In one specific implementation, the injection tube 150 is a transparent tube, and the bottom of both the piston 140 and the injection tube 150 is conical. The transparent design facilitates observation of the injection process, and the conical bottom design helps to fully inject the liquid.

[0041] The working principle of this suction catheter flushing device is as follows: In use, the flushing tube 170 is connected to the suction catheter, and the suction tube 160 is inserted into the saline bottle. The motor 125 is started, driving the threaded rod 124 to rotate. The threaded rod 124, through a threaded transmission principle, drives the moving block 126 to move. The moving block 126 drives the sliding rod 130 and the piston 140 to move. When the piston 140 moves upward, a negative pressure is formed in the injection tube 150, opening the one-way valve 180 of the suction tube 160, and the saline bottle is drawn into the injection tube 150. Simultaneously, the one-way valve 180 of the flushing tube 170 closes. When the piston 140 moves downward, the saline in the injection tube 150 is pushed outward, closing the one-way valve 180 of the suction tube 160, while simultaneously opening the one-way valve 180 of the flushing tube 170, allowing the saline bottle to be drawn into the injection tube 150. Water is injected into the suction catheter, and this process is repeated to rinse the suction catheter, avoiding the need to disassemble the suction catheter, repeatedly aspirate, replenish saline, and continue rinsing. This reduces steps and improves efficiency. Furthermore, the sliding ring 220 can be pulled up, compressing the spring 213. Then, the sliding ring 220 is rotated, causing the upright rod 212 and the injection tube 150 to rotate. This rotation of the injection tube 150 adjusts the position of the suction tube 160 and the rinsing tube 170, adapting to different patients or suction catheter positions, thus improving practicality. Then, the sliding ring 220 is released, and the spring 213 returns to its elasticity, pushing the sliding ring 220 so that the positioning rod 230 at the bottom of the sliding ring 220 falls into the corresponding positioning groove 111, restricting the rotation of the injection tube 150.

[0042] It should be noted that the specific model and specifications of motor 125 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0043] The power supply and principle of motor 125 are clear to those skilled in the art and will not be described in detail here.

[0044] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
