[0001] The present invention relates to the technical field of medical devices, and in particular to a glaucoma intraocular pressure regulating and drainage device. Background Art

[0002] The Glaucoma Intraocular Pressure Control Drainage Device is an implantable medical device used to treat refractory glaucoma. It lowers intraocular pressure by actively draining the aqueous humor. It primarily consists of a drainage disc, a drainage tube, and a pressure-regulating valve. The drainage disc is fixed to the sclera, and the drainage tube is implanted in the anterior chamber, draining the aqueous humor into the subconjunctival space to form a filtering bleb. This device boasts high biocompatibility and stable drainage efficiency, making it suitable for glaucoma patients who have not responded to traditional surgery. Regular postoperative monitoring of intraocular pressure and the status of the filtering bleb is required to ensure long-term efficacy.

[0003] The intraocular pressure regulating and drainage device in the prior art may cause impurities in the eye or mixtures in the aqueous humor to flow together during the drainage process, causing blockage, thereby reducing the flow volume and even affecting the flow effect. The impurities cannot be collected and sensed for targeted treatment, resulting in inconvenience in use. Summary of the Invention

[0004] Technical problems solved In response to the shortcomings of the existing technology, the present invention provides a glaucoma intraocular pressure regulating and drainage device, which solves the problem that impurities in the eye or mixtures in the aqueous humor circulate together and cause blockage, thereby reducing the circulation volume and even affecting the circulation effect, and the impurities cannot be collected and sensed for targeted treatment.

[0005] Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a glaucoma intraocular pressure regulating and drainage device, comprising a drainage disc, a drainage chamber fixedly connected to the middle of the drainage disc, a flow tube fixedly connected to both ends of the bottom of the drainage chamber, a filter cavity fixedly connected to one side of the middle of the flow tube, a valve cavity fixedly connected to the other side of the middle of the flow tube, a fixed inclined net fixedly connected to the middle of the filter cavity, a first arc-shaped guide plate provided on one side of the top of the fixed inclined net, a second arc-shaped guide plate provided on the other side of the top of the fixed inclined net, the first arc-shaped guide plate and the second arc-shaped guide plate both fixedly connected to the inner wall of the filter cavity, and a collection cavity fixedly connected to one side of the filter cavity; Arc-shaped baffles are fixedly connected to both sides of the inner top of the valve cavity, an arc-shaped groove is opened at the bottom end of the arc-shaped baffle, and the bottom end of the arc-shaped groove abuts against a sealing ball plug. The end of the circulation tube away from the drainage chamber is fixedly connected to a circulation branch tube, and the middle part of the circulation branch tube is fixedly connected to the drainage tube.

[0006] Preferably, the bottom end of the sealing ball plug is fixedly connected to a fixing frame, both ends of the fixing frame are penetrated by sliding rods, and a flow groove is opened between the arc-shaped baffles.

[0007] Preferably, arc-shaped support blocks are fixedly connected to both sides of the inner bottom end of the valve cavity, and the top end of the arc-shaped support block is fixedly connected to the sliding rod.

[0008] Preferably, a support spring is fixedly connected between the fixing bracket and the arc-shaped support block, and the support spring is sleeved on the outside of the sliding rod.

[0009] Preferably, an opening is provided between the filter cavity and the collecting cavity, and a silicone sheet is fixedly connected to the upper middle portion of the collecting cavity.

[0010] Preferably, a liquid level sensor is fixedly connected to the inner top of the collection chamber.

[0011] Preferably, a plurality of needle and thread holes are provided on both sides of the drainage plate, and a contact wire plate is fixedly connected to the middle of the needle and thread holes at one end.

[0012] A method for regulating intraocular pressure and drainage in glaucoma, comprising the following specific drainage methods: Step 1: First, surgically implant the drainage disc on the equatorial sclera surface, with the front end 9-10 mm from the corneal limbus. Use 6-0 or 5-0 sutures to pass through the needle and thread holes and suture it to the superficial sclera. Use the abutment plate to increase the fixation of the sutures and prevent them from loosening. Step 2: The drainage tube is then punctured into the anterior chamber and viscoelastic is injected. The drainage tube is trimmed to a length of 2-3 mm and inserted into the anterior chamber, covered with a foreign scleral lens to prevent exposure. During the drainage process, the aqueous humor flows through the flow tube connected to the drainage chamber. During the flow process, the aqueous humor will pass through the filter cavity and valve cavity, and then flow through the flow branch to the drainage tube, completing the flow function. Step 3: When the aqueous humor in the eye passes through the filtration chamber, it first flows through the arc-shaped arrangement of the first arc-shaped guide plate and the second arc-shaped guide plate, which can flow the liquid toward the higher end of the fixed inclined net. During the flow, the liquid penetrates, and the impurities after penetration are filtered by the fixed inclined net. Due to the arrangement of the fixed inclined net, the impurities can flow toward the inclined end and enter the interior of the collection chamber. At the same time, since the liquid is discharged from the higher end to the lower end, the impurities can also be flushed toward the inclined end to prevent clogging problems. Step 4: After the impurities are stored inside the collection chamber, part of the liquid will also be stored inside the collection chamber. At this time, due to the setting of the silicone sheet, it can effectively open when impurities enter and close after entering. When there are more impurities and liquid, the liquid can be discharged through the fixed inclined net, and the impurities will accumulate. After accumulation, they will conflict with the liquid level sensor. After the liquid contacts the sensor, it can send a signal to the controller. After receiving the signal, the controller can send a signal to the wireless signal transmission module and send a signal through the mobile phone receiving module to sense the treatment of the drainage plate. Step 5: The liquid will flow into the interior of the valve cavity again, and the pressure will resist the sealing ball plug, thereby realizing opening and facilitating the circulation of the liquid. When the liquid refluxes, the support spring elastically supports the fixing frame to reset, and the sealing ball plug resists the arc baffle to achieve the sealing effect of preventing backflow.

[0013] Beneficial effects The present invention provides a glaucoma intraocular pressure regulation and drainage device, which has the following beneficial effects: The present invention is provided with: a first arc-shaped guide plate, a second arc-shaped guide plate, a fixed inclined net and a collection chamber. Through the arc-shaped setting of the first arc-shaped guide plate and the second arc-shaped guide plate, the liquid can flow to the higher end of the fixed inclined net. During the flow, the liquid penetrates, and the impurities after penetration are filtered by the fixed inclined net. Due to the setting of the fixed inclined net, the impurities can flow to the inclined end and enter the interior of the collection chamber. Through this structure, the impurities and liquid can be filtered and separated, preventing the impurities from clogging the pipeline.

[0014] The present invention is provided with: a fixed inclined net, a liquid level sensor, a controller and a wireless signal transmission module. When there are a lot of impurities and liquid, the liquid can be discharged through the fixed inclined net, and the impurities will accumulate. After accumulation, they will conflict with the liquid level sensor. After the liquid contacts the sensor, it can send a signal to the controller. After receiving the signal, the controller can send a signal to the wireless signal transmission module and send a signal through the mobile phone receiving module. It can sense the processing of the drainage plate. Through this structure, impurity pretreatment can be intelligently sensed, thereby improving portability.

[0015] The present invention is provided with: a valve chamber, a sealing ball plug, a support spring and an arc-shaped baffle. The liquid will flow into the interior of the valve chamber again, and the pressure will resist the sealing ball plug, thereby realizing opening and facilitating the circulation of the liquid. When the liquid refluxes, the support spring elastically supports and resets the fixed frame support, and the sealing ball plug resists the arc-shaped baffle, achieving the effect of sealing to prevent backflow.
