Deformable lacrimal passage irrigation device

Abstract

This application relates to the technical field of medical devices, and particularly to a deformable lacrimal duct irrigation device. By adjusting the device, the pressure inside the support tube is adjusted, and then the hardness of the support tube is adjusted, so that the patient feels more comfortable during the lacrimal duct irrigation process. Since both the delivery tube and the support tube are configured as flexible pipes, the delivery tube and the support tube can move along the patient's lacrimal duct. When there is a blockage, the pressure inside the support tube is increased to increase the hardness of the support tube, so that the support tube can continue to move forward with the delivery tube. When the patient feels uncomfortable, the pressure inside the support tube is reduced, and then the hardness of the support tube is reduced to reduce the force exerted by the support tube on the patient's lacrimal duct, thereby making the patient feel comfortable. Since both the delivery tube and the support tube are configured as flexible pipes, even if there are some deviations in the operation actions, the force exerted on the lacrimal duct can be reduced through the deformation of the delivery tube and the support tube, thereby reducing the risk of damage to the lacrimal duct and reducing the operation difficulty.

Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a deformable lacrimal duct irrigation device. Background Art

[0002] Lacrimal duct irrigation is an operative technique of injecting liquid into the lacrimal duct to dredge obstructions at different parts, which can be used both as a diagnostic technique and as a treatment method.

[0003] Currently, a syringe needle is usually used for lacrimal duct irrigation. The syringe needle is usually installed at the front part of a syringe, and the shape of the syringe needle is designed according to the angle between the lacrimal duct and the ocular surface. Normal saline or other drugs are injected into the lacrimal duct via the syringe needle through the syringe to achieve the effects of flushing and expanding the lacrimal duct.

[0004] The syringe needle is usually made of a rigid material and is difficult to deform. Therefore, during the actual operation, it often makes the patient feel uncomfortable, and the operation is difficult. A slight deviation in movement may cause damage to the patient's lacrimal duct, leading to medical accidents. Moreover, due to the limitations of the shape and size of the syringe needle, the syringe needle often cannot cover all areas of the lacrimal duct, so that the flushing effect is difficult to meet the expected requirements.

[0005] It can be seen that how to make the patient feel comfortable during lacrimal duct irrigation and reduce the risk of damage to the lacrimal duct is a technical problem to be solved urgently. Summary of the Invention

[0040] The beneficial effects achieved by this application are as follows: Since the support tube is arranged along the conveying direction of the conveying tube and the support tube and the conveying tube are attached to each other, the support tube can support the conveying tube and cause the conveying tube to deform with the deformation of the support tube.

During the process of gradually increasing the pressure inside the support tube, the shape of the support tube gradually presents a preset shape, so that the conveying tube can fit the shape of the patient's lacrimal duct, and thus the conveying tube can enter the patient's lacrimal duct more smoothly and make the patient more comfortable. During the process of flushing the patient's lacrimal duct using a deformable intraductal flushing device provided by this application, first, the pressure inside the support tube is increased to a first pressure threshold through an adjustment device, so that the structural strength of the support tube is sufficient to support the conveying tube to extend into the patient's lacrimal duct. During the process of the conveying tube extending into the patient's lacrimal duct, the pressure inside the support tube is adjusted through the adjustment device, and thus the hardness of the support tube is adjusted, so that the patient feels more comfortable during the lacrimal duct flushing process. Since both the conveying tube and the support tube are configured as flexible pipes, the conveying tube and the support tube can move along the patient's lacrimal duct. When there is a blockage, the pressure inside the support tube is increased to increase the hardness of the support tube, so that the support tube can continue to move forward with the conveying tube. When the patient feels uncomfortable, the pressure inside the support tube is reduced, and thus the hardness of the support tube is reduced, so as to reduce the acting force of the support tube on the patient's lacrimal duct, thereby making the patient feel comfortable. Since the conveying tube and the support tube can move along the patient's lacrimal duct and are configured as flexible pipes, the area of lacrimal duct flushing can be expanded, and thus the flushing effect can be improved. Since both the conveying tube and the support tube are configured as flexible pipes, even if there are some slight deviations in the operating actions, the acting force on the lacrimal duct can be reduced through the deformation of the conveying tube and the support tube, and thus the risk of damage to the lacrimal duct is reduced and the operation difficulty is reduced. In this way, the patient feels comfortable during the lacrimal duct flushing process and the risk of damage to the lacrimal duct is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Please refer to Figures 1 to 3 and Figure 7 , in some embodiments of the present application, a deformable lacrimal duct irrigation device 10 provided by the present application includes: 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 is attached to the delivery tube 20. The adjustment device 40 is used to adjust the pressure inside the support tube 30. Among them, both the delivery tube 20 and the support tube 30 are configured as flexible tubes.

[0057] It can be understood that since the support tube 30 is arranged along the delivery direction of the delivery tube 20, and the support tube 30 is attached to the delivery tube 20, the support tube 30 can support the delivery tube 20 and cause the delivery tube 20 to deform along with the deformation of the support tube 30.

[0058] The shape of the support tube 30 can be designed such that as the pressure inside the support tube 30 gradually increases, the shape of the support tube 30 gradually assumes a preset shape, thereby enabling the delivery tube 20 to fit the shape of the patient's lacrimal duct, and further making the process of the delivery tube 20 entering the patient's lacrimal duct smoother and the patient more comfortable.

[0059] During the process of flushing the patient's lacrimal duct using a deformable intraductal flushing device provided by the present application, first, the pressure inside the support tube 30 is 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] During the process of the delivery tube 20 extending into the patient's lacrimal duct, the pressure inside the support tube 30 is adjusted through 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 both the delivery tube 20 and the support tube 30 are configured as flexible pipes, the delivery tube 20 and the support tube 30 can move along the patient's lacrimal duct. When there is a blockage, the pressure inside 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 inside the support tube 30 is reduced, thereby reducing the hardness of the support tube 30, so as to reduce the force exerted by the support tube 30 on the patient's lacrimal duct, thus 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 pipes, the area of lacrimal duct flushing can be expanded, thereby improving the flushing effect. Since both the delivery tube 20 and the support tube 30 are configured as flexible pipes, even if there are some slight deviations in the operating actions, the force exerted on the lacrimal duct can be reduced through the deformation of the delivery tube 20 and the support tube 30, thereby reducing the risk of damage to the lacrimal duct and reducing the operation difficulty.

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

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

[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 substance may further 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 lacrimal 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 substance may also be a substance equivalent to the cleaning liquid.

[0075] By making the filling substance equivalent to the cleaning liquid, even if the support tube 30 leaks, it will not pose a hazard to the patient, thus improving the safety of the lacrimal 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 around the outside 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, when the support tube 30 expands, it can effectively support the outer wall of the delivery tube 20, thereby making the pipeline space inside the delivery tube 20 smoother, and thus ensuring the effectiveness of the lacrimal duct cleaning. By wrapping the tubular sheath around the outside of the support tube 30, the part of the deformable lacrimal duct irrigation device 10 extending into the lacrimal duct contacts the lacrimal duct wall with a smooth outer wall, thereby reducing the risk of damage to the lacrimal duct and making the movement of the delivery tube 20 in the lacrimal duct smoother.

[0078] Please refer to Figures 1 to 2 and Figure 7 , in some embodiments of the present application, the number of support tubes 30 is at least two, and the support tubes 30 are distributed dispersedly on the outer wall of the delivery tube 20.

[0079] By supporting the delivery tube 20 from different parts by multiple support tubes 30, the outer wall of the delivery tube 20 can be smoothly unfolded, thereby making the pipeline space inside the delivery tube 20 smoother, and thus ensuring the effectiveness of the lacrimal duct cleaning.

[0080] By supporting the delivery tube 20 from different parts by multiple support tubes 30, the delivery tube 20 can be deformed from different parts and directions, thereby making the delivery tube 20 more adaptable to the shape of the lacrimal duct, enabling the delivery tube 20 to move more smoothly in the lacrimal duct, making the patient feel more comfortable during the lacrimal duct irrigation process, and enabling the delivery tube 20 to reach a wider range of positions in the lacrimal duct, further expanding the irrigation range and improving the irrigation effect.

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

[0082] In some embodiments of the present application, the adjustment device 40 includes: an input adjustment component 41, an output adjustment component 42, and a control module. The input adjustment component 41 is used to open and close the input port of the support tube 30. The output adjustment 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 adjustment component 41 and the output adjustment component 42 to control the pressure in 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 through a delivery pump. When it is necessary to increase the pressure in the support tube 30, the control module controls the input adjustment component 41 to open the input port of the support tube 30, so that the filling material can smoothly enter the support tube 30. When it is necessary to discharge the filling material out of the support tube 30, the control module controls the output adjustment component 42 to open the output port of the support tube 30, and then, through the squeezing force of the support tube 30 on the lacrimal duct and the tension of the inner wall of the support tube 30 itself, the filling material naturally discharges from the output port of the output tube 426, thereby reducing the pressure in the support tube 30.

[0084] In some embodiments of the present application, the adjustment device 40 further includes: a buffer chamber 416 and an input tube 417. The input ports of all the support tubes 30 are communicated with the internal space of the buffer chamber 416. The input tube 417 is communicated with the internal space of the buffer chamber 416, and the input tube 417 is used to allow the external filling material 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] During the process that the input adjustment gradually closes 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 415 attract each other, and then the first seal 414 closely adheres to the outer wall of the input port of the support tube 30, thereby closing the input port of the support tube 30.

[0089] Through the mutual cooperation of the first electromagnet module 411 and the first permanent magnet 415, the input port of the support tube 30 is opened or closed, thereby simplifying the control structure, avoiding introducing too many structures, and thus improving the structural reliability of the input adjustment assembly 41.

[0090] Please refer to Figures 1 to 7 , in some embodiments of the present application, the output adjustment assembly 42 includes: a second electromagnet module 421, a second connecting member 422, a second limiting member 423, a second seal 424, and a second permanent magnet 425. The position of the second electromagnet module 421 is relatively fixed with respect to the position of the output port of the support tube 30. The second connecting member 422 passes through the output port of the support tube 30. The second limiting member 423 is disposed at one end of the second connecting member 422. The second limiting member 423 is located on one side of the output port of the support tube 30, and the size of the second limiting member 423 is larger than the size of the output port of the support tube 30. The second seal 424 is disposed at the other end of the second connecting member 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 with respect to the position of the second seal 424, and the second permanent magnet 425 interacts with the second electromagnet module 421. Wherein, the control module is used to control the polarity direction of the second electromagnet module 421.

[0091] During the process that the output adjustment assembly 42 opens 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 repel each other, and then the second seal 424 leaves the output port of the support tube 30, thereby opening the output port of the support tube 30. After the second seal 424 leaves the output port of the support tube 30, the second limiting member 423 abuts against the inner wall of the output port of the support tube 30 to prevent the second seal 424 from getting out of the controllable range.

[0092] During the process that the output adjustment gradually closes the output port of the support tube 30, 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 425 attract each other, and then the second seal 424 closely adheres to the outer wall of the output port of the support tube 30, thereby closing the output port of the support tube 30.

[0093] Through the mutual cooperation of the second electromagnet module 421 and the second permanent magnet 425, the output port of the support tube 30 is opened or closed, thereby simplifying the control structure, avoiding introducing too many structures, and thus improving the structural reliability of the output adjustment assembly 42.

[0094] In some embodiments of the present application, an output tube 426 is provided at the output port of the support tube 30. The internal space of the support tube 30 is communicated with the outside through the output tube 426, and the output adjustment assembly 42 is arranged in the output tube 426.

[0095] By arranging the output adjustment assembly 42 in the output tube 426, the output adjustment assembly 42 is protected through the output tube 426, avoiding damage to the output adjustment assembly 42 caused by external interference, and also avoiding the backflow of external substances into the interior of the support tube 30 through the output port of the support tube 30 after the output adjustment assembly 42 is opened.

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

[0097] The filter element 427 blocks foreign objects from the outside, thereby avoiding jamming of the output adjustment assembly 42 by foreign objects from the outside and improving the safety and reliability of the output adjustment assembly 42.

[0098] In some embodiments of the present application, the adjustment device 40 further includes: a collection chamber 428 and a discharge pipe 429. All the output tubes 426 are communicated with the internal space of the collection chamber 428. The discharge pipe 429 is communicated with the internal 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] After the collection chamber 428 uniformly collects the filling materials discharged from each support tube 30, they are then discharged through the discharge pipe 429, thus 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 is designed separately from the adjustment device 40.

[0101] The support tube 30 and the delivery tube 20 are respectively connected to the delivery tube 20 through connectors. After the deformable lacrimal passage irrigation device 10 provided in the present application is used to irrigate the lacrimal passage of a patient, the used support tube 30 and delivery tube 20 are removed, and after the new support tube 30 and delivery tube 20 are installed on the adjustment device 40, the lacrimal passage can be irrigated again through the deformable lacrimal passage irrigation device 10 provided in the present application. By replacing the support tube 30 and the delivery tube 20, cross-infection is avoided, and by retaining the adjustment device 40, resource waste is avoided and the use cost is reduced.

[0102] In some embodiments of the present application, a deformable lacrimal passage irrigation device 10 provided in the present application further includes a flushing buffer chamber 21. The flushing buffer chamber 21 is communicated with 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-irrigating the lacrimal passage, 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 lacrimal passage cleaning process, and further making the lacrimal passage cleaning process safer and more stable.
