Deformable lacrimal passage flushing device

Abstract

The invention relates to the technical field of medical instruments, in particular to a deformable lacrimal passage flushing device. The pressure intensity in the supporting tube is adjusted through the adjusting device, and then the hardness of the supporting tube is adjusted, so that a patient feels more comfortable in the lacrimal passage flushing process. Due to the fact that the conveying pipe and the supporting pipe are both flexible pipes, the conveying pipe and the supporting pipe can move along the lacrimal passage of the patient. When jamming occurs, the intensity of pressure in the supporting pipe is increased to increase the hardness of the supporting pipe, so that the supporting pipe can drive the conveying pipe to continue to move forwards. And when the patient feels uncomfortable, the pressure in the supporting tube is reduced, so that the hardness of the supporting tube is reduced, the acting force of the supporting tube on the lacrimal passage of the patient is reduced, and the patient feels comfortable. As the conveying pipe and the supporting pipe are both configured to be flexible pipes, even if the operation action has a certain deviation, the acting force on the lacrimal passage can be reduced through deformation of the conveying pipe and the supporting pipe, the risk of damage to the lacrimal passage is further reduced, and the operation difficulty is reduced.

Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a deformable lacrimal duct flushing device. Background Art

[0002] Tear duct irrigation is a procedure that involves injecting fluid into the tear duct to clear blockages in different parts of the tear duct. It can be used as both a diagnostic technique and a treatment method.

[0003] At present, the tear duct is usually flushed with a flushing needle, which is usually installed at the front of the syringe. The shape of the flushing needle is designed according to the angle between the tear duct and the ocular surface. Physiological saline or other drugs are injected into the tear duct through the flushing needle through the syringe to achieve the effect of flushing and expanding the tear duct.

[0004] Flushing needles are usually made of hard materials that are difficult to deform. Therefore, in actual operation, patients often feel uncomfortable and have difficulty in operation. A slight deviation in movement may cause damage to the patient's tear duct and lead to medical accidents. In addition, due to the limitations of the shape and size of the flushing needle, the flushing needle often cannot cover all areas of the tear duct, so that the flushing effect is difficult to meet the expected requirements.

Of course, they are only examples, and the purpose is not to limit the present invention.

[0056] See also Figures 1 to 3 and Figure 7 In some embodiments of the present application, the present application provides a deformable lacrimal duct flushing device 10, comprising: a delivery tube 20, a support tube 30 and an adjustment device 40. The delivery tube 20 is used to deliver the cleaning liquid. The support tube 30 is arranged along the delivery direction of the delivery tube 20, and the support tube 30 and the delivery tube 20 are attached to each other. The adjustment device 40 is used to adjust the pressure in the support tube 30. Among them, the delivery tube 20 and the support tube 30 are both configured as flexible pipes.

[0057] It can be understood that since the support tube 30 is arranged along the conveying direction of the conveying tube 20 and the support tube 30 and the conveying tube 20 are attached to each other, the support tube 30 can support the conveying tube 20 and make the conveying tube 20 deform along with the deformation of the support tube 30 .

[0058] The shape of the support tube 30 can be designed. As the pressure in the support tube 30 gradually increases, the shape of the support tube 30 gradually presents a preset shape, so that the delivery tube 20 can fit the shape of the patient's tear duct, thereby making the delivery tube 20 enter the patient's tear duct more smoothly and making the patient more comfortable.

[0059] In the process of flushing the patient's lacrimal duct using a deformable internal duct flushing device provided in the present application, the pressure in the support tube 30 is first increased to a first pressure threshold through the adjustment device 40 so that the structural strength of the support tube 30 is sufficient to support the delivery tube 20 to extend into the patient's lacrimal duct.

[0060] When the delivery tube 20 is extended into the patient's lacrimal duct, the pressure in the support tube 30 is adjusted by the adjustment device 40, thereby adjusting the hardness of the support tube 30, so that the patient feels more comfortable during the lacrimal duct flushing process.

[0061] Since the delivery tube 20 and the support tube 30 are both configured as flexible tubes, the delivery tube 20 and the support tube 30 can move along the patient's tear duct. When a jam occurs, the pressure in the support tube 30 is increased to increase the hardness of the support tube 30 so that the support tube 30 can continue to move forward with the delivery tube 20. When the patient feels uncomfortable, the pressure in the support tube 30 is reduced, thereby reducing the hardness of the support tube 30 to reduce the force of the support tube 30 on the patient's tear duct, thereby making the patient feel comfortable.

[0062] Since the delivery tube 20 and the support tube 30 can move along the patient's lacrimal duct and are configured as flexible tubes, the lacrimal duct flushing area can be expanded, thereby improving the flushing effect. Since the delivery tube 20 and the support tube 30 are both configured as flexible tubes, even if there is a slight deviation in the operation, the force on the lacrimal duct can be reduced by the deformation of the delivery tube 20 and the support tube 30, thereby reducing the risk of damage to the lacrimal duct components and reducing the difficulty of operation.

[0063] In this way, the patient feels comfortable during the tear duct irrigation process and the risk of damage to the tear duct is reduced.

[0064] In some embodiments of the present application, the end of the delivery tube 20 is configured as a hard tube.

[0065] By configuring the end of the delivery tube 20 as a hard tube, the delivery tube 20 and the support tube 30 can enter the patient's lacrimal duct more smoothly, and the movement direction of the delivery tube 20 in the patient's lacrimal duct can be more controllable. Since the end of the delivery tube 20 is configured as a hard tube, the patient's lacrimal duct can be opened more smoothly, and the delivery tube 20 can move more smoothly in the patient's lacrimal duct. The end of the support tube 30 is configured as a flexible tube, so as to prevent the hard tube at the end of the delivery tube 20 from directly contacting the patient's lacrimal duct, and then a buffer pad is formed between the patient's lacrimal duct wall and the hard tube through the support tube 30 to protect the patient's lacrimal duct from damage.

[0066] The length of the hard tube at the end of the delivery tube 20 is configured to be 5 mm to 10 mm.

[0067] It should be pointed out that hard tubing means that the hardness of the tubing is enough to open the patient's tear duct, that is, the hard tubing can still make the pipe space inside the tubing have the ability to transport under the pressure of the patient's tear duct wall. Flexible tubing means that when the tubing enters the patient's tear duct, it will be deformed by the pressure of the patient's tear duct wall, and when the pressure inside the tubing increases, the flexible tubing will be propped up, so that the overall structural strength of the flexible tubing is increased.

[0068] In some embodiments of the present application, the pressure in the support tube 30 is increased by injecting a filling substance into the support tube 30 , and the pressure in the support tube 30 is reduced by discharging the filling substance in the support tube 30 .

[0069] It is understandable that, in the process of injecting the filling material into the support tube 30, the support tube 30 gradually expands, thereby gradually increasing the structural strength and hardness of the support tube 30, thereby enabling the delivery tube 20 to move more smoothly in the lacrimal duct. In the process of the filling material in the support tube 30 being discharged outward, the size, structural strength and hardness of the support tube 30 gradually decrease, thereby reducing the force of the support tube 30 on the lacrimal duct, thereby reducing the risk of damage to the lacrimal duct and making the patient feel more comfortable during the lacrimal duct flushing process. In the process of the delivery tube 20 moving in the lacrimal duct, the cleaning liquid is sprayed out from the liquid outlet of the delivery tube 20 at a certain pressure, and the lacrimal duct is flushed by the cleaning liquid.

[0070] In some embodiments of the present application, the filling substance includes ordinary air.

[0071] Ordinary air is injected into the support tube 30 through the air pump device, thereby increasing the pressure in the support tube 30, thereby gradually expanding the support tube 30, and thereby gradually increasing the structural strength and hardness of the support tube 30. Ordinary air is used to fill the support tube 30, thereby reducing material costs. When the ordinary air is discharged from the support tube 30, the ordinary air can be directly discharged into the atmosphere without causing pollution.

[0072] In some embodiments of the present application, the filling material may also include harmless gases such as nitrogen, helium or carbon dioxide, or a mixture thereof.

[0073] The support tube 30 is filled with a special gas, thereby reducing the risk of infection during the tear duct cleaning process and ensuring the safety of the cleaning process. Since the harmless gas has little impact on the atmospheric environment, it can also be directly discharged into the atmospheric space.

[0074] In some embodiments of the present application, the filling material may also be a material equivalent to the cleaning fluid.

[0075] By making the filling material equal to the cleaning fluid, even if the support tube 30 leaks, it will not cause harm to the patient, thereby improving the safety of the tear duct cleaning process.

[0076] In some embodiments of the present application, the support tube 30 is attached to the outer wall of the delivery tube 20 in a spiral manner, and a tubular sheath is wrapped on the outer side of the support tube 30 .

[0077] By making the support tube 30 attached to the outer wall of the delivery tube 20 in a spiral manner, the support tube 30 can effectively support the outer wall of the delivery tube 20 after expansion, so that the pipeline space in the delivery tube 20 is smoother, thereby ensuring the effectiveness of tear duct cleaning. By wrapping the tubular mantle on the outside of the support tube 30, the part of the deformable tear duct flushing device 10 extending into the tear duct is in contact with the tear duct wall with a smooth outer wall, thereby reducing the risk of tear duct damage and making the delivery tube 20 move more smoothly in the tear duct.

[0078] See also Figure 1 to Figure 2 and Figure 7 In some embodiments of the present application, the number of the support tubes 30 is at least two, and the support tubes 30 are dispersed on the outer wall of the delivery tube 20 .

[0079] The delivery tube 20 is supported from different positions by multiple support tubes 30, so that the outer wall of the delivery tube 20 can be smoothly unfolded, and the pipeline space in the delivery tube 20 is smoother, thereby ensuring the effectiveness of tear duct cleaning.

[0080] The delivery tube 20 is supported from different positions by multiple support tubes 30, so that the delivery tube 20 can be deformed from different positions and directions, so that the delivery tube 20 can better adapt to the shape of the tear duct, so that the delivery tube 20 can move more smoothly in the tear duct, and make the patient feel more comfortable during the tear duct flushing process, and the delivery tube 20 can reach a wider position of the tear duct, further expanding the flushing range and improving the flushing effect.

[0081] When the pressure in one of the support tubes 30 is lower than the pressure in the other support tube 30, the support tube 30 with higher pressure will push the delivery tube 20 toward the support tube 30 with lower pressure, thereby causing the delivery tube 20 to bend toward the support tube 30 with lower pressure. In this way, by adjusting the pressure in each support tube 30, the bending degree and bending direction of the delivery tube 20 can be adjusted, thereby effectively controlling the shape of the delivery tube 20.

[0082] In some embodiments of the present application, the regulating device 40 includes: an input regulating component 41, an output regulating component 42, and a control module. The input regulating component 41 is used to open and close the input port of the support tube 30. The output regulating component 42 is used to open and close the output port of the support tube 30. The control module is used to control the input regulating component 41 and the output regulating component 42 to control the pressure inside the support tube 30 by inputting and outputting the filling material inside the support tube 30.

[0083] The filling material is delivered to the support tube 30 by the delivery pump. When the pressure in the support tube 30 needs to be increased, the input adjustment component 41 is controlled by the control module to open the input port of the support tube 30, so that the filling material can smoothly enter the support tube 30. When the filling material needs to be discharged out of the support tube 30, the output adjustment component 42 is controlled by the control module to open the output port of the support tube 30, and then the filling material is naturally discharged from the output port of the output tube 426 through the squeezing force of the tear duct on the support tube 30 and the tension of the inner wall of the support tube 30 itself, thereby reducing the pressure in the support tube 30.

[0084] In some embodiments of the present application, the regulating device 40 further includes: a buffer chamber 416 and an input pipe 417. The input ports of all support pipes 30 are in communication with the internal space of the buffer chamber 416. The input pipe 417 is in communication with the internal space of the buffer chamber 416, and the input pipe 417 is used to allow external filling materials to enter the buffer chamber 416.

[0085] The filling material is delivered to the buffer chamber 416 through the input pipe 417 by the delivery pump, thereby increasing the pressure in the buffer chamber 416. When it is necessary to increase the pressure in a certain support tube 30, the input regulating assembly 41 corresponding to the support tube 30 is controlled by the control module to open the input port of the support tube 30, so that the filling material in the buffer chamber 416 can enter the support tube 30 to fill the internal space of the support tube 30, thereby increasing the pressure in the support tube 30. By making the input ports of all support tubes 30 communicate with the internal space of the buffer chamber, the timing of the filling material in the buffer chamber 416 entering the support tube 30 can be controlled by controlling the action of the input regulating assembly 41 corresponding to different support tubes 30, thereby simplifying the control process. Through the setting of the buffer chamber 416, the delivery pump only needs to deliver the filling material to different support tubes 30 through one input pipe 417, thereby simplifying the pipeline layout of the deformable tear duct flushing device 10, thereby making the tear duct flushing process more convenient and controllable.

[0086] See also Figures 1 to 7 In some embodiments of the present application, the input adjustment component 41 includes: a first electromagnet module 411, a first connector 412, a first stopper 413, a first seal 414 and a first permanent magnet 415. The position of the first electromagnet module 411 remains relatively fixed with the position of the input port of the support tube 30. The first connector 412 is arranged through the input port of the support tube 30. The first stopper 413 is arranged at one end of the first connector 412, the first stopper 413 is located on one side of the input port of the support tube 30, and the size of the first stopper 413 is larger than the size of the input port of the support tube 30. The first seal 414 is arranged at the other end of the first connector 412, the first seal 414 is located on the other side of the input port of the support tube 30, and the first seal 414 is used to seal the input port of the support tube 30. The position of the first permanent magnet 415 remains relatively fixed with the position of the first seal 414, and the first permanent magnet 415 interacts with the first electromagnet module 411. The control module is used to control the polarity direction of the first electromagnet module 411 .

[0087] In the process of the input adjustment component 41 opening the input port of the support tube 30, the polarity direction of the first electromagnet module 411 is controlled by the control module to be the same as the polarity direction of the first permanent magnet 415, so that the first electromagnet module 411 and the first permanent magnet 415 module repel each other, and then the first sealing member 414 leaves the input port of the support tube 30, so that the input port of the support tube 30 is opened. When the first sealing member 414 leaves the input port of the support tube 30, the first stopper 413 abuts against the inner wall of the input port of the support tube 30 to prevent the first sealing member 414 from leaving the controllable range.

[0088] In the process of input adjustment gradually closing the input port of the support tube 30, the control module controls the polarity direction of the first electromagnet module 411 to be opposite to the polarity direction of the first permanent magnet 415, so that the first electromagnet module 411 and the first permanent magnet module 415 attract each other, and then the first sealing member 414 is tightly attached to the outer wall of the input port of the support tube 30, so that the input port of the support tube 30 is closed.

[0089] The first electromagnet module 411 cooperates with the first permanent magnet 415 to open or close the input port of the support tube 30 , thereby simplifying the control structure and avoiding the introduction of excessive structures, thereby improving the structural reliability of the input adjustment component 41 .

[0090] See also Figures 1 to 7 In some embodiments of the present application, the output adjustment component 42 includes: a second electromagnet module 421, a second connector 422, a second stopper 423, a second seal 424 and a second permanent magnet 425. The position of the second electromagnet module 421 is relatively fixed to the position of the output port of the support tube 30. The second connector 422 is arranged through the output port of the support tube 30. The second stopper 423 is arranged at one end of the second connector 422, the second stopper 423 is located on one side of the output port of the support tube 30, and the size of the second stopper 423 is larger than the size of the output port of the support tube 30. The second seal 424 is arranged at the other end of the second connector 422, the second seal 424 is located on the other side of the output port of the support tube 30, and the second seal 424 is used to seal the output port of the support tube 30. The position of the second permanent magnet 425 is relatively fixed to the position of the second seal 424, and the second permanent magnet 425 interacts with the second electromagnet module 421. Among them, the control module is used to control the polarity direction of the second electromagnet module 421.

[0091] In the process of the output adjustment component 42 opening the output port of the support tube 30, the control module controls the polarity direction of the second electromagnet module 421 to be the same as the polarity direction of the second permanent magnet 425, so that the second electromagnet module 421 and the second permanent magnet 425 module repel each other, and then the second sealing member 424 leaves the output port of the support tube 30, so that the output port of the support tube 30 is opened. When the second sealing member 424 leaves the output port of the support tube 30, the second stopper 423 abuts against the inner wall of the output port of the support tube 30 to prevent the second sealing member 424 from leaving the controllable range.

[0092] In the process of gradually closing the output port of the support tube 30 by output adjustment, the control module controls the polarity direction of the second electromagnet module 421 to be opposite to the polarity direction of the second permanent magnet 425, so that the second electromagnet module 421 and the second permanent magnet module 425 attract each other, and then the second sealing member 424 is closely attached to the outer wall of the output port of the support tube 30, so that the output port of the support tube 30 is closed.

[0093] The output port of the support tube 30 is opened or closed by the cooperation between the second electromagnet module 421 and the second permanent magnet 425 , thereby simplifying the control structure and avoiding the introduction of excessive structures, thereby improving the structural reliability of the output adjustment component 42 .

[0094] In some embodiments of the present application, an output pipe 426 is provided at the output port of the support tube 30 , the internal space of the support tube 30 is connected to the outside through the output pipe 426 , and the output adjustment component 42 is disposed in the output pipe 426 .

[0095] By disposing the output regulating component 42 in the output pipe 426, the output regulating component 42 is protected by the output pipe 426 to avoid external interference from damaging the output regulating component 42 and to avoid foreign matter from flowing back into the support tube 30 through the output port of the support tube 30 when the output regulating component 42 is turned on.

[0096] In some embodiments of the present application, a filter 427 is provided at one end of the output tube 426 away from the output port.

[0097] The filter element 427 blocks foreign matter from outside, thereby preventing the foreign matter from blocking the output regulating component 42 , thereby improving the safety and reliability of the output regulating component 42 .

[0098] In some embodiments of the present application, the regulating device 40 further includes: a collection chamber 428 and a discharge pipe 429. All output pipes 426 are in communication with the inner space of the collection chamber 428. The discharge pipe 429 is in communication with the inner space of the collection chamber 428, and the discharge pipe 429 is used to discharge the filling material in the collection chamber 428 to the outside.

[0099] The filling materials discharged from each support tube 30 are collected uniformly by the collection chamber 428 and then discharged through the discharge pipe 429 , thereby facilitating the management of the filling materials discharged from the support tube 30 .

[0100] In some embodiments of the present application, the combination formed by the support tube 30 and the delivery tube 20 and the adjustment device 40 are designed separately.

[0101] The support tube 30 and the delivery tube 20 are connected to the delivery tube 20 through a joint, respectively. After the deformable tear duct flushing device 10 provided by the present application is used to flush the tear duct of the patient, the used support tube 30 and delivery tube 20 are removed, and new support tubes 30 and delivery tubes 20 are installed in the adjustment device 40, and the tear duct can be flushed again by the deformable tear duct flushing device 10 provided by the present application. By replacing the support tube 30 and the delivery tube 20, cross infection can be avoided, and by retaining the adjustment device 40, resource waste can be avoided and the use cost can be reduced.

[0102] In some embodiments of the present application, a deformable lacrimal duct flushing device 10 provided by the present application also includes a flushing buffer chamber 21, which is connected to the delivery tube 20, and the internal space size of the flushing buffer chamber 21 is larger than the cross-sectional size of the delivery channel of the delivery tube 20.

[0103] During the process of re-rinsing the tear duct, the cleaning liquid is pumped by an external pump so that the cleaning liquid first enters the flushing buffer chamber 21 and then enters the delivery tube 20, thereby avoiding the influence of changes in the working parameters of the external pump on the tear duct cleaning process, thereby making the tear duct cleaning process safer and more stable.
