Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The intraocular pressure adjusting device mainly comprises a container and a pressure adjusting device; the container comprises a first opening which is butted with a pressure regulating device, and the pressure regulating device is used for regulating the pressure in the container through the first opening; the container further comprises an abutment assembly and a second opening provided in the abutment assembly; the abutting assembly is used for abutting against the face area around the eyeball of the user in the circumferential direction, so that the eyeball of the user is isolated from the outside air, and the pressure in the container is borne through the second opening. The principle of intraocular pressure regulation is that the cornea of the user's eyeball deforms when it encounters external pressure (i.e., pressure from within the container), and the user's eyeball deforms as the local pressure around the eye changes, thereby causing the intraocular pressure to also change. In general, the pressure in the container can be determined based on the internal pressure of the eyeball of the user, thereby achieving the adjustment of the intraocular pressure.

The container is mainly used for providing an internal environment isolated from the outside air for the user's eyeball, and under such an environment, the user's eyeball is subjected to the pressure from the inside of the container. The user mentioned above refers to the subject of intraocular pressure regulation. The surface of at least a portion of the user's eyeball is indirectly exposed to pressure from the container when a contact lens or other membrane is present on the surface of the user's eyeball, and is directly exposed to pressure within the container when the user's eyeball is directly exposed to the aforementioned internal environment. The foregoing other membranes include a membrane of an tonometric measurement device, and the membrane has a sensor disposed thereon, and the membrane is configured to be in close contact with an eyeball of a user, and the sensor of the membrane generates a corresponding electrical signal to a processor of the tonometric measurement device as an environment around the eyeball of the user changes or as a surface curvature of the eyeball of the user changes, and the processor can obtain a change of the intraocular pressure of the user or calculate the intraocular pressure of the user.

The pressure from the inside of the container may be set as required, and may be higher or lower than the atmospheric pressure outside the container, or may be equal to the atmospheric pressure outside the container.

The container at least comprises a cavity capable of containing gas, the second opening is communicated with the cavity, and the pressure adjusting equipment can adjust the pressure of the gas in the cavity so as to adjust the pressure in the container. The material of the walls of the chamber may comprise a deformable material, which may cause a significant change in the shape of the chamber when the pressure within the chamber changes; the material of the walls of the chamber may be non-deformable, in which case the shape of the chamber does not typically change significantly when the pressure within the chamber changes.

The air in the chamber may generally comprise air output by the pressure regulating device, but of course, other types of air may be included, depending on the actual need for intraocular pressure regulation. Generally, a type of gas may be selected that avoids damage or irritation to the eye. In addition, the content of the gas in the cavity can be determined according to actual needs and can be adjusted by pressure adjusting equipment.

The pressure regulating device may be used to regulate the pressure in the container in various ways, for example, the pressure regulating device may change the pressure in the cavity by pumping air into or out of the cavity, in which case, the pressure regulating device may include an air pump and an air pump, or the pressure regulating device may include an air pump with air pumping and air conveying functions. When the material of the wall of the chamber may comprise a deformable material, the pressure regulating device may also deform the chamber by applying pressure or tension to the deformable material, for example using hydraulic or pneumatic pressure, to change the pressure in the chamber, and if necessary, the pressure regulating device may also simultaneously pump or evacuate the chamber to compensate for gas losses in the chamber.

The container comprises a cavity body and an abutting assembly, wherein the abutting assembly is mainly in annular abutting connection with a face area around an eyeball of a user, so that the eyeball of the user is isolated from the outside air, and the pressure in the container is borne through a second opening. The configuration of the abutment assembly may also be varied, for example in the form of a tube or other hollow structure, one end of the abutment assembly being for abutment against the facial area around the user's eyeball and the other end being for communication with the cavity.

The aforementioned keep apart from the outside air is that intraocular pressure adjusting device is in the course of the work, and when butt subassembly and the regional hoop butt of face around the eyeball of user, because butt subassembly and the regional inseparable laminating of face around the eyeball, and make the outside air unable to pass through the region of inseparable laminating continuously, freely. This indicates that, the isolation from the outside air does not mean absolute and constant isolation, and during the actual operation of the intraocular pressure regulating device, the contact surface between the abutment member and the facial region around the eyeball may be in a separated, partially separated, or partially loosened state in a short time due to the turning, tilting, or shaking of the head of the user, which should also be considered as allowable.

When the intraocular pressure adjusting device is used, the face area around the eyeball of a user is abutted to the abutting component of the container so as to bear the pressure from the inside of the container. The pressure regulating device can regulate the pressure in the container through the first opening, so that the pressure born by the eyeball of the user from the outside of the eyeball is changed, and the intraocular pressure of the eyeball of the user is indirectly regulated. Meanwhile, the intraocular pressure adjusting device is also beneficial to adjusting the intraocular pressure to a desired range in place, directly, quickly and accurately, can better relax optic nerves and has good effect on daily eye health care.

In some embodiments, the container is constructed as shown in FIG. 1. In fig. 1, the container 100 includes a square box 110, and a first opening 111 is opened at a first side of the square box 110; the abutment assembly 120 is provided on a second side of the square box. The square box 110 includes a hollow cavity which is communicated with the first opening 111. The chamber is also in communication with a second opening 112 that opens to a second side of the square box 110. In figure 1, the abutment assembly 120 is a mask for abutting against the face of a user. To improve the sealing and comfort of the fit, the portion of the abutment assembly 120 that fits against the user's face may be made of a flexible material. When the facial area around the user's eyeball abuts against the abutment assembly 120, the two eyeballs of the user can face the inside of the square case 110, i.e., the hollow cavity, through the second opening 112. The pressure regulating device may be adapted to change the pressure in the square shaped case 110 by docking the first opening 111 to input gas into the cavity of the square shaped case 110 or drawing gas out of the cavity of the square shaped case 110, and in operation, the user's eyeball will be exposed to the pressure from the square shaped case 110 through the second opening 112. When the pressure regulating device continuously inputs gas into the cavity of the square box 110 through the first opening 111, the eyeball of the user will feel the continuously changing pressure from inside the square box 110; as the pressure regulating device continuously draws gas out of the cavity of the square shaped case 110 through the first opening 111, the eyeball of the user will also be able to feel the changing pressure from within the square shaped case 110.

In some embodiments, the abutting assembly 120 and the square box 110 may be integrally formed or welded. In other cases, the abutting assembly 120 and the square box 110 may be detachably connected, for example, the edge of the abutting assembly 120 is connected to the second side of the square box 110 by bolts, or the abutting assembly 120 and the second side of the square box 110 are fixed by clamping. Of course, the abutting assembly 120 and the square box 110 may be connected in other detachable or non-detachable manners, and are not limited herein.

In some embodiments, the dimensions of the inner or outer surface of the square box 110 may be: the length is 40cm, the width is 50cm and the height is 60cm. The square box 110 may be made of PMMA (polymethyl methacrylate, also called acrylic), PS (Polystyrene), or other materials.

The cavity in the square box 110 may have a regular shape or an irregular shape, and is not limited thereto.

The volume, volume or mass of the square box 110 can be designed according to actual requirements, for example, the square box 110 can be portable, and is convenient to be transferred to different places; for example, the square box 110 may be fixed, and may be fixed on a base or a platform, so that the face of the user is not easily shaken or loosened to cause pressure leakage during the abutting process with the abutting assembly 120.

In some embodiments, the first opening 111, the abutment assembly 120, and the second opening 112 may be disposed on the same side.

In some embodiments, the container is configured as shown in fig. 3. In fig. 3, the container 300 includes a cavity 303 and a first opening 301 and two second openings 302 communicating with the cavity 303. In fig. 3, the second opening 302 is located at the first end of the tube 310, and the second end of the tube 310 is communicated with the cavity 303, in which case, the tube 310 can be regarded as an abutting component, and when the first end of the tube 310 abuts on the facial area around the eyeball of the user, the gas in the cavity 303 will contact with the eyeball of the user through the second opening 302, so as to change the pressure on the surface of the eyeball of the user.

In some embodiments, fig. 4 illustrates yet another possible configuration of a container. In fig. 4, a container 400 includes a cavity 403, a first opening 401, and a second opening 402. Wherein the first opening 401 is not communicated with the cavity 403. The wall material of the cavity 403 is a deformable material, and the pressure regulating device can deliver gas through the first opening 401 to reduce the volume of the cavity 403, so as to change the pressure in the cavity 403; the pressure regulating device may also draw air through the first opening 401 to increase the volume of the cavity 403, thereby changing the pressure within the cavity 403. The conduit communicating the cavity 403 with the second opening 402 may be considered an abutment assembly. Fig. 4 shows that the second opening 402 is one, which means that the intraocular pressure of one eyeball of the user can be adjusted according to actual needs, so that one eyeball of the user can bear the pressure from the inside of the cavity 403 through the second opening 402.

In some embodiments, the facial area around the user's eyeball comprises the user's eye socket; the abutting assembly comprises a fitting part; the second opening is arranged on the attaching part; the fitting part is used for being abutted against the eye sockets of the user in an annular mode, at least one eyeball of the user is isolated from the outside air, and the eyeball bears the pressure in the container through the second opening. In fig. 1, the area of the outer edge of the second opening 112 may be considered a fit that may be used to abut the user's eye socket. In fig. 3, the first end of the conduit 310 may also be considered a fitting, and may also be used to abut the eye socket of the user. Of course, the fitting portion may also adopt the related configuration mentioned in the following description, or adopt other configurations, and is not particularly limited herein.

It will be appreciated from the principles disclosed in some of the foregoing embodiments that the container may provide intraocular pressure adjustment to one or both of the user's eyes, depending on the configuration of the container. In addition, the intraocular pressure regulating device may also be used to provide different pressures to different eyeballs of the user, in particular, in some embodiments, the number of containers is two; the pressure regulating device is used for regulating the pressure in each container through the first opening of the container; the abutting component of each container is used for abutting against the face area around one eyeball of a user in the circumferential direction, so that the corresponding eyeball is isolated from the outside air, and the pressure in the container is borne through the second opening of the container. In this case, the pressure regulating device may include two sets of pressure pumps, one set of pressure pumps for regulating the pressure in one container and the other set of pressure pumps for regulating the pressure in the other container. In some specific cases, the two containers may be disposed in the same box or in the same object; of course, in other cases, the two containers may be separated, and are not particularly limited.

In some embodiments, the cavity of the container and the second opening may be connected by a connecting tube. The container at this time comprises a connecting pipe and a cavity; the two ends of the connecting pipe are respectively in sealed butt joint with the cavity and the abutting component, and the connecting pipe is communicated with the second opening; the first opening is communicated with the cavity. One specific configuration of a container that meets this situation is shown in fig. 5.

In fig. 5, the container includes a case 510, a connection pipe 520, and an abutment assembly 530, wherein a chamber for containing gas is provided in the case 510. The two ends of the connection pipe 520 are a first end 521 and a second end 522. The first end 521 can be abutted with an abutting port 512 formed at one side of the housing 510, so that the connecting pipe 520 is communicated with the cavity inside the housing 510. Second end 522 may communicate two second openings 531 through a tee pipe (not shown). The abutment assembly 530 includes a fitting 532 outboard of the second opening 531, the fitting 532 being for abutment with the eye socket of the user. Abutment assembly 530 further includes a nasal mask 533 for receiving the nose when the user's face is fitted to abutment assembly 530.

Fig. 5 also reveals that the container may have more openings, for example, a box 510 having a third opening 513 in addition to a first opening 511 for interfacing with a pressure regulating device, a docking opening 512. In some embodiments, the third opening 513 may be used to dock a pressure regulating device to provide one more gas or suction opening. In other embodiments, the third opening 513 may be used to allow a lead to extend into the housing 510, and in this case, a sensor, such as a pressure sensor, a temperature sensor, or a gas sensor, may be disposed in the housing 510 to monitor the environment inside the housing 510.

The abutting assembly 530 in fig. 5 can be bound to the face of the user by a strap, and the connection tube 520 can be a flexible tube, and at this time, the user can move his head while accepting the process of intraocular pressure adjustment without worrying about air leakage.

In some embodiments, as shown in figure 6, the abutment assembly 600 is designed to resemble goggles or swimming goggles. In figure 6, the abutment assembly 600 includes a front panel having a first edge 610, which may be transparent or non-transparent, and a front opening 631 for receiving a first opening of the container. The surface of the front panel may be flat or curved. Abutment assembly 600 further includes a fitting 620, which fitting 620 is shown simplified as a closed curve, which may correspond to a physical object having a thickness and width. The attaching portion 620 is used to abut against a face region 901 around the eyeball of the user as shown in fig. 9. To improve the fit, the fit portion 620 may be made of a flexible material. In the abutment member 600 of fig. 6, the ring-shaped portion between the first edge 610 and the fitting portion 620 may be referred to as a side portion, and the side portion may be provided with a fixing region 640, and the fixing region 640 is used for connecting with a strap (not shown) which may be tied to the head of the human body, so that the abutment member 600 is bound to the head of the human body, thereby making the fitting portion 620 abut against the face region around the eyeball of the user, which is similar to a case that goggles or swimming goggles are bound to the head of the human body. Of course, the abutment member 600 may also abut against the face area around the eyeball of the user by other means, and is not limited herein. The first opening of the container may also be open on the side of the abutment assembly 600, i.e. one side opening 632 may be provided as the first opening of the container. In fig. 6, the notch bounded by the attachment portion 620 may be considered a second opening of the container. The hollow structure inside the abutment assembly 600 may be considered as a cavity of the container.

The embodiment of figure 6 discloses that the first opening of the container may open onto the abutment assembly and that the cavity of the container may be provided within the abutment assembly, depending on the configuration of the abutment assembly.

In different embodiments, the abutment assembly may have different configurations. The area of the user's face around the eyeball that is in circumferential abutment with the abutment assembly may be understood in connection with some of the examples listed in figures 7, 8 and 9. Fig. 7 illustrates the general shape of a user's face 700 in some embodiments. Fig. 8 shows a face area 801 around the right eye of the user in circumferential abutment with the abutment member, and a face area 802 around the left eye of the user, based on the shape of the face 700 of the user in fig. 7. In fig. 8, the face area around the eyeball of the user is two annular areas, one annular area (face area 801 around the right eyeball of the user) surrounding the left eyeball of the user, and the other annular area (face area 802 around the left eyeball of the user) surrounding the right eyeball of the user. Fig. 9 shows yet another form of the face region around the eyeball of the user, and in fig. 9, the face region 901 around the eyeball of the user encloses the left eyeball of the user, the right eyeball of the user, and a part of the bridge of the nose of the user at the same time. Corresponding to the situation of figure 9, the fit of the abutment component may have an opening that is adapted to the shape of the facial region 901 around the user's eyeball in figure 9, which opening may be considered as a second opening, so that in use the fit can have a higher degree of fit when in close proximity to the facial region 901 around the user's eyeball.

In some embodiments, the container may be transparent in its entirety or at least in one region. For example, the square box 110 of FIG. 1, the wall material of FIG. 3 forming the cavity 303, or the box 510 of FIG. 5 may be made of a transparent material. At this time, other people except the user can observe the expression or eye reaction of the user through the transparent material so as to evaluate the adaptation state of the intraocular pressure adjustment of the user.

In some embodiments, the gas temperature of the cavity within the vessel is adjustable. Specifically, a temperature sensor may be provided in the container to obtain the temperature of the gas in the container; and comparing the acquired gas temperature with a preset temperature value, and inputting warm air or cold air into the container through the first opening by the pressure regulating equipment so as to regulate the gas temperature of the cavity in the container to reach the preset temperature value. Therefore, the comfort degree of the eyeballs of the user in the intraocular pressure adjusting process can be further improved.

In some embodiments, an OCT (Optical Coherence Tomography) device may be disposed within the container, and the OCT device may be used to scan the eye to obtain images that may be used for analysis of the ocular structure.

In some embodiments, a tonometric measurement device may also be disposed within the container, or a probe portion of the tonometric measurement device may be included within the container. The tonometric measurement device may be in direct contact with the user's eyeball, for example, there are tonometric measurement devices that include a deformable membrane having a sensor disposed therein that is conformable to the user's eyeball. The tonometric measurement device may also be one that does not directly contact the user's eyeball, for example, some tonometric measurement devices measure the tonus by capturing light reflected signals of the user's eyeball.

Of course, other devices for monitoring the environment inside the container or collecting the eye data of the user may be provided in the container, and are not limited herein.

In some embodiments, as shown in fig. 2, the pressure regulating device 200 includes a pressure pump assembly 210 and a controller 220; the pressure pump assembly 210 interfaces with the first opening of the container; the controller 220 is used to control the pressure pump assembly 210 to regulate the pressure within the reservoir. Generally, the pressure pump assembly 210 includes a pump that may be used for gas delivery and/or gas extraction. The controller 220 can regulate the pressure within the container by controlling the amount of gas or suction applied by the pressure pump assembly 210 to the cavity within the container. The controller 210 may be implemented in hardware using at least one of a Programmable Logic Array (PLA), a Field Programmable Gate Array (FPGA), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a general purpose processor, or other programmable logic device.

In some embodiments, the pressure pump assembly 210 comprises a vacuum pump, a pressurization pump, and a proportional valve, the vacuum pump is in communication with the first opening through the proportional valve, the pressurization pump is in communication with the first opening through the proportional valve, the controller 220 can control the vacuum pump to be turned on so as to draw the gas from the first opening of the container interior, and the controller 220 can also control the pressurization pump to be turned on so as to deliver the gas from the first opening to the container interior. The controller 220 may also control the flow of gas through the first opening by controlling the proportional valve.

In some embodiments, the controller 220 is configured to control the pressure pump assembly 210 to adjust the pressure in the container to a preset target pressure according to a preset pressure variation curve, wherein the absolute difference between the target pressure and the pressure outside the container is within 30 mmHg. The pressure change curve records the target pressures corresponding to different time nodes. The absolute difference between the target pressure and the pressure outside the container is within 30mmHg, which means that the absolute difference between the maximum target pressure or the minimum target pressure corresponding to the pressure change curve and the pressure outside the container is within 30mmHg, and the numerical value of the range conforms to the safety range of the external pressure which can be borne by the eyeballs of the ordinary users.

In some embodiments, the preset pressure profile is such that, as time progresses, the target pressure first increases and finally decreases until it coincides with the pressure outside the container. Specifically, after the facial area around the user's eyeball abuts the abutment assembly, the controller 220 first controls the pressure pump assembly 210 to increase the pressure in the container according to such pressure change profile, and in the final stage, adjusts the pressure in the container back to the pressure outside the container to be consistent, that is, to be consistent with the atmospheric pressure in the field.

In some embodiments, the controller 220 may control the pressure pump assembly 210 to first increase the pressure within the container and hold it for a period of time, and then decrease the pressure within the container to atmospheric pressure in the field. Of course, in other embodiments, the controller 220 may control the pressure pump assembly 210 to increase the pressure in the container in a plurality of pressurization periods, and after the current pressurization period is over, the pressure in the container is kept constant for a preset time period before the next pressurization period comes, so that the user's eyes can be prevented from being impacted by a large pressure change in a short time.

In some embodiments, in the preset pressure variation curve, the slope of the line segment corresponding to the target pressure rise may be set according to actual needs. That is, the controller 220 can control the pressure pump assembly 210 to regulate the pressure within the container at a preset pressurization rate. For example, a pressurization rate of 14.7 to 73.6mmHg/min may be used to increase the pressure in the vessel, although a value of one fifth or one tenth of the aforementioned pressurization rate may also be used to increase the pressure in the vessel. Similarly, in some embodiments, the slope of the line segment corresponding to the target pressure drop in the preset pressure variation curve may be set according to actual needs.

In some embodiments, the pressure regulating device 200 further comprises a command input assembly (not shown) for inputting the pressure parameter and the time parameter; the controller 220 is configured to obtain a pressure parameter and a time parameter, and determine a pressure variation curve according to the pressure parameter and the time parameter. In general, the pressure parameter is used to represent a target pressure value in the container, which may be determined for different users based on the internal pressure of their eyeball. The time parameter is used to indicate the duration of the intraocular pressure adjustment and may be, for example, 20 minutes, 30 minutes, or other time. Specifically, the controller 220 may determine the corresponding pressure variation curve according to the preset pressure increasing slope and/or pressure decreasing slope, in combination with the input pressure parameter and the time parameter.

In some embodiments, the pressure regulating device 200 further comprises a pressure sensor (not shown) for detecting the pressure within the container; the controller 220 is used for acquiring the detection data of the pressure sensor and controlling the pressure pump assembly 210 to regulate the pressure in the container according to the detection data. Typically, the pressure sensor may be disposed in a cavity within the container. The detection data of the pressure sensor is usually used to directly indicate the actual measurement value of the pressure in the container, but the controller 220 may process the detection data to obtain the actual measurement value of the pressure in the container. The controller 220 is configured to obtain the detection data of the pressure sensor, and control the pressure pump assembly 210 to regulate the pressure in the container according to the detection data, and may specifically include any one of the following manners:

(1) When the measured pressure value in the container exceeds the preset safety range, the controller 220 controls the pressure pump assembly 210 to regulate the pressure in the container and continuously acquire the detection data of the pressure sensor until the measured pressure value in the container returns to the preset safety range; at this time, the pressure pump assembly 210 can adjust the pressure in the container through the first opening of the container, and the pressure pump assembly 210 can also adjust the pressure in the container by opening other openings of the container to release the pressure;

(2) When the difference between the measured pressure value in the container and the preset target pressure exceeds the preset threshold, the controller 220 controls the pressure pump assembly 210 to regulate the pressure in the container and continuously obtain the detection data of the pressure sensor until the difference between the measured pressure value in the container and the preset target pressure does not exceed the preset threshold.

In some embodiments, the pressure regulating device 200 further comprises a signal output assembly (not shown); the controller 220 is further configured to send a prompt message to the signal output component when the detected data has an abnormal characteristic; the signal output component is used for receiving the prompt information of the controller and prompting according to the prompt information. The signal output component may be a display, speaker, vibrator, or other machine that may be used to provide information cues. The detected data has abnormal features including, but not limited to, features indicating that the measured pressure value in the container exceeds a preset safety range, that the difference between the measured pressure value in the container and a preset target pressure exceeds a preset threshold, or that the pressure in the container leaks. When the pressure within the container leaks, it is more likely that the abutment assembly will come into a loose fit with the facial area around the user's eyeball. When the measured pressure value in the container is always smaller than the preset pressure value within the preset time interval, the controller 220 determines that the detected data has an abnormal characteristic, and at this time, a flashing or highlighted signal may be generated by the display for prompting.

In one aspect, a method for applying an intraocular pressure regulating device provided by the present application comprises the steps of:

step S1, determining that a facial area around eyeballs of a user is abutted to an abutting component of a container;

s2, detecting a pressure parameter and a time parameter input by a medical worker or other personnel through an instruction input assembly of the pressure adjusting device by a controller of the pressure adjusting device;

and S3, the controller acquires the pressure parameter and the time parameter and determines a pressure change curve according to the pressure parameter and the time parameter.

S4, controlling a pressing force variation curve of a pressure pump assembly of the pressure regulating device by a controller to regulate the pressure in the container to a preset target pressure;

s5, simultaneously acquiring detection data of the pressure sensor by the controller, and controlling the pressure pump assembly to adjust the pressure in the container according to the detection data so as to keep the difference value between the pressure in the container and the target pressure below a preset threshold value or keep the pressure in the container within a preset safety range;

and S6, in the final intraocular pressure adjusting stage, when the controller controls the pressing force change curve of the pressure pump assembly to adjust the pressure in the container to the value of the atmospheric pressure outside the container, prompting the end of intraocular pressure adjustment or prompting the user to separate from the abutting assembly.

The specific technical details related to the above steps may include the technical details mentioned in the foregoing embodiments related to the intraocular pressure regulating device, and are not described herein again.

All possible combinations of the technical features in the above embodiments may not be described for the sake of brevity, but should be considered as being within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, and these are all within the scope of protection of the present application.
