[0046] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The present application is further described in detail below in conjunction with the accompanying drawings.

[0048] The embodiments of the present application disclose an intraocular pressure meter and an intraocular pressure self-testing method that are convenient for patients to test themselves.

[0049] like Figure 1 As shown, a tonometer convenient for patients to self-test includes a tonometer body 1, a probe head 2 and a periocular support device 3; the probe head 2 is arranged on the tonometer body 1; the periocular support device 3 is retractably arranged on the tonometer body 1, and the periocular support device 3 is arranged on the tonometer body 1 around the probe head 2, and the periocular support device 3 is used to support the periphery of the eye.

[0050] Specifically, the tonometer body 1 is a rebound tonometer, and the probe head 2 is arranged at the center of one side of the tonometer body 1. Its main working principle is to contact the cornea through the probe head 2, and there is a magnetic sensing device inside the probe head 2. The instrument emits a tiny, precisely controllable force to make the probe head 2 touch the cornea lightly, and then the probe rebounds, and the sensor inside the instrument detects parameters such as the rebound speed and distance. These parameters have a certain functional relationship with the intraocular pressure, and the intraocular pressure value is calculated by the built-in microprocessor according to a pre-set algorithm.

[0051] The periorbital support device 3 is in the shape of a hollow cylinder as a whole. In order to avoid the probe head 2, a through hole is provided on the periorbital support device 3 which passes through both ends, and the probe head 2 is located in the through hole.

[0052] One end of the periocular support device 3 is arranged on the tonometer body 1, and the other end is used to support the periphery of the eye. On the one hand, it plays a supporting role, and on the other hand, it can keep a certain distance between the probe head 2 and the eyeball, which is convenient for patients to self-measure intraocular pressure.

[0053] When the user uses the tonometer that is convenient for patients to measure intraocular pressure by themselves, the periocular support device 3 is placed against the periorbital area of ​​the eye to be tested. At this time, the probe head 2 in the periocular support device 3 can be directly opposite the eye to be tested, so that the eye to be tested can be conveniently tested. Due to the support of the periocular area by the periocular support device 3, the patient can conveniently and safely keep the probe head 2 at a suitable distance from the eye to be tested, so that the patient can independently operate to measure intraocular pressure. At the same time, due to the retractable nature of the periocular support device 3, before performing intraocular pressure testing on the eye to be tested, the distance from the probe head 2 to the eye can be adjusted by adjusting the length of the periocular support device 3 to prevent the distance from the probe head 2 to the eye to be tested from being too short to cause damage to the eye or the distance from the probe head 2 to the eye to be tested from being too long to affect the accuracy of intraocular pressure testing, thereby solving the problem that the existing tonometer cannot be used independently by patients for intraocular pressure testing.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, the periocular support device 3 includes a first periocular support component 31 and a second periocular support component 32. The first periocular support component 31 and the second periocular support component 32 can be retractably arranged on the tonometer body 1, and the first periocular support component 31 and the second periocular support component 32 are arranged around the probe head 2, and the first periocular support component 31 and the second periocular support component 32 are detachably arranged.

[0055] Specifically, the first periocular support component 31 and the second periocular support component 32 are both semi-cylindrical. Since the first periocular support component 31 and the second periocular support component 32 are detachable, on the one hand, they can be spliced ​​into a cylindrical whole to support the periphery of the eye, allowing users to self-test intraocular pressure; on the other hand, according to the specific periphery of the user's eye, a more suitable first periocular support component 31 or second periocular support component 32 can be selected for deployment and assembly.

[0056] like Figure 1 , Figure 2 and Figure 3As shown, the first periocular support assembly 31 includes a first support fixing member 311, a first connecting member 312 and a first support member 313, and the two ends of the first connecting member 312 are respectively connected to the first support fixing member 311 and the first support member 313; the second periocular support assembly 32 includes a second support fixing member 321, a second connecting member 322 and a second supporting member 323, and the two ends of the second connecting member 322 are respectively connected to the second support fixing member 321 and the second supporting member 323; the first connecting member 312 and the second connecting member 322 are retractable members; the first support fixing member 311 and the second support fixing member 321 are detachable, and the first support fixing member 311 and the second support fixing member 321 are both detachable from the tonometer body 1; the first support member 313 and the second support member 323 are both used to support the periphery of the eye.

[0057] Specifically, the first supporting fixture 311 and the second supporting fixture 321 are both detachably arranged from the tonometer body 1 , so as to facilitate the installation of the first periocular support assembly 31 and the second periocular support assembly 32 on the tonometer body 1 .

[0058] At least one first supporting fixture 311 is provided, and at least one first supporting fixture 311 is provided between the first supporting fixture 311 and the first supporting member 313. If the number of the first supporting fixture 311 is greater than or equal to two, at least two first supporting fixtures 311 are provided between the first supporting fixture 311 and the first supporting member 313 at intervals.

[0059] Similarly, at least one second supporting fixture 321 is provided, and at least one second supporting fixture 321 is provided between the second supporting fixture 321 and the second supporting member 323. If the number of the second supporting fixture 321 is greater than or equal to two, at least two second supporting fixtures 321 are provided between the second supporting fixture 321 and the second supporting member 323.

[0060] One first supporting fixture 311 and the second supporting fixture 321 are provided, or at least two first supporting fixtures 311 and the second supporting fixtures 321 are provided and are spaced apart from each other, so that the user can observe the working state and working condition of the probe head 2 located in the through hole through the gap between the two first supporting fixtures 311, between the two second supporting fixtures 321, or between the first supporting fixtures 311 and the second supporting fixtures 321.

[0061] like Figure 1 , Figure 2 and Figure 3 As shown, an annular threaded hole 11 is provided on the outer circumference of the tonometer body 1 around the probe head 2 ; the first supporting fixture 311 and the second supporting fixture 321 are both threadedly connected to the annular threaded hole 11 .

[0062] Specifically, the first supporting fixture 311 and the second supporting fixture 321 are in the shape of a semicircular ring, and the first supporting fixture 311 and the second supporting fixture 321 are detachably connected via a limiting groove and a limiting block.

[0063] For example, the first two ends of the first supporting fixing member 311 are respectively provided with a first sliding groove 3111 and a first sliding block 3112, and the second two ends of the second supporting fixing member 321 are respectively provided with a second sliding block and a second sliding groove 3211, the first sliding groove 3111 and the second sliding block are slidably connected, and the first sliding block 3112 and the second sliding groove 3211 are slidably connected, thereby realizing the installation of the first supporting fixing member 311 and the second supporting fixing member 321.

[0064] It should be noted that both ends of the first supporting fixture 311 may be sliding grooves or sliding blocks, and similarly, both ends of the second supporting fixture 321 may be sliding blocks or sliding grooves that can slidably cooperate with the first supporting fixture 311 .

[0065] Furthermore, the sliding grooves on the first supporting fixture 311 and the second supporting fixture 321 are both dovetail grooves, and the sliding blocks on the first supporting fixture 311 and the second supporting fixture 321 are both dovetail blocks slidably connected to the dovetail grooves.

[0066] The slidable connection between the dovetail groove and the dovetail block can provide high-precision guidance. The dovetail block can be tightly embedded in the dovetail groove. This shape allows the dovetail block to move only in a specific direction in the dovetail groove. In addition, the sides of the dovetail groove and the dovetail block fit tightly, limiting the degrees of freedom in other directions, thereby ensuring the linearity and accuracy of the movement.

[0067] The outer surfaces of the first support fixture 311 and the second support fixture 321 are both provided with external threads. When the first support fixture 311 and the second support fixture 321 are connected together, the external threads on the first support fixture 311 and the external threads on the second support fixture 321 are aligned at the cross section. The first support fixture 311 and the second support fixture 321 connected together can be screwed with the annular threaded hole 11, thereby realizing the installation of the periocular support device 3 on the tonometer body 1.

[0068] like Figure 3As shown, the first connecting member 312 includes a first telescopic portion 3121, a first accommodating portion 3122 and a first telescopic fixing member 3123, one end of the first accommodating portion 3122 is connected to the first supporting fixing member 311, and the other end is provided with a first telescopic hole 3122a, one end of the first telescopic portion 3121 is slidably arranged in the first telescopic hole 3122a, and the other end is connected to the first supporting member 313; the first telescopic fixing member 3123 is used to limit the length of the first telescopic portion 3121 extending from the first telescopic hole 3122a; the second connecting member 322 includes a second telescopic portion, a second accommodating portion and a second telescopic fixing member, one end of the second accommodating portion is connected to the second supporting fixing member 321, and the other end is provided with a second telescopic hole, one end of the second telescopic portion is slidably arranged in the second telescopic hole, and the other end is connected to the second supporting member 323; the second telescopic fixing member is used to limit the length of the second telescopic portion extending from the second telescopic hole.

[0069] Specifically, the first telescopic portion 3121 and the first accommodating portion 3122 are slidably arranged, and the length of the first connecting member 312 can be adjusted by adjusting the length of the first telescopic portion 3121 extending from the first telescopic hole 3122a, thereby adjusting the length of the first periorbital support assembly 31. After determining the length of the first telescopic portion 3121 extending from the first telescopic hole 3122a, the first telescopic fixing member 3123 is used to fix the current position of the first telescopic portion 3121, thereby fixing the length of the first periorbital support assembly 31, and facilitating the subsequent support of the first periorbital support assembly 31 on the periorbital area of ​​the user.

[0070] Similarly, the second telescopic portion and the second accommodating portion are slidably arranged, and the length of the second connecting member 322 can be adjusted by adjusting the length of the second telescopic portion extending from the second telescopic hole, thereby adjusting the length of the second periorbital support assembly 32. After determining the length of the second telescopic portion extending from the second telescopic hole, the second telescopic fixing member is used to fix the current position of the second telescopic portion, thereby fixing the length of the second periorbital support assembly 32, and facilitating the subsequent support of the user's periorbital area by the second periorbital support assembly 32.

[0071] The length adjustment of the first connecting member 312 and the second connecting member 322 realizes the adjustable length of the first supporting fixture 311 and the second supporting fixture 321, so that by adjusting the length of the first supporting fixture 311 and the second supporting fixture 321, on the one hand, the undulating state of the skin around the eyes can be adapted; on the other hand, the distance from the probe head 2 to the eyeball can be adjusted to adapt to the eyeball size of different users.

[0072] like Figure 3 , Figure 4 and Figure 5As shown, in one implementation of the embodiment of the present application, a plurality of first clamping holes 3122b are arranged at intervals on the first accommodating portion 3122, the first telescopic fixing member 3123 is arranged on the first telescopic portion 3121, the first telescopic fixing member 3123 is a rebound member, and the first telescopic fixing member 3123 and the plurality of first clamping holes 3122b are all clamped together; a plurality of second clamping holes are arranged at intervals on the second accommodating portion, the second telescopic fixing member is arranged on the second telescopic portion, the second telescopic fixing member is a rebound member, and the second telescopic fixing member and the plurality of second clamping holes are all clamped together.

[0073] Specifically, a plurality of first engaging holes 3122b are arranged at intervals along the sliding direction of the first telescopic portion 3121 in the first telescopic hole 3122a. Since the first telescopic fixing member 3123 is arranged on the first telescopic portion 3121, after the first telescopic fixing member 3123 extends out of one of the first engaging holes 3122b, it limits the sliding of the first telescopic portion 3121 in the first telescopic hole 3122a, thereby fixing the length of the first connecting member 312.

[0074] When the length of the first connecting member 312 needs to be adjusted, it is only necessary to press the first telescopic fixing member 3123 so that the first telescopic fixing member 3123 is no longer clamped in the current first clamping hole 3122b, and the length of the first telescopic portion 3121 extending from the first telescopic hole 3122a can be adjusted. After the length of the first telescopic portion 3121 extending from the first telescopic hole 3122a is determined, the first telescopic fixing member 3123 extends from the current upper first clamping hole 3122b under the action of elastic potential energy, thereby again limiting the sliding of the first telescopic portion 3121 in the first telescopic hole 3122a and fixing the current length of the first connecting member 312.

[0075] Similarly, multiple second clamping holes are arranged at intervals along the sliding direction of the second telescopic part in the second telescopic hole. Since the second telescopic fixing piece is arranged on the second telescopic part, after the second telescopic fixing piece extends out of one of the second clamping holes, it limits the sliding of the second telescopic part in the second telescopic hole, thereby fixing the length of the second connecting piece 322.

[0076] When the length of the second connecting member 322 needs to be adjusted, it is only necessary to press the second telescopic fixing member so that the second telescopic fixing member is no longer clamped in the current second clamping hole, and the length of the second telescopic portion extending from the second telescopic hole can be adjusted. After the length of the second telescopic portion extending from the second telescopic hole is determined, the second telescopic fixing member extends from the current upper second clamping hole under the action of elastic potential energy, thereby again limiting the sliding of the second telescopic portion in the second telescopic hole and fixing the current length of the second connecting member 322.

[0077] like Figure 3 , Figure 6 and Figure 7 As shown, in another implementation of the embodiment of the present application, a first connecting hole 3122c is provided on the first accommodating portion 3122, the first connecting hole 3122c is connected to the first telescopic hole 3122a, the first telescopic fixing member 3123 is screwed to the first connecting hole 3122c, and the first telescopic fixing member 3123 abuts against the first telescopic portion 3121; a second connecting hole is provided on the second accommodating portion, the second connecting hole is connected to the second telescopic hole, the second telescopic fixing member is screwed to the second connecting hole, and the second telescopic fixing member abuts against the second telescopic portion.

[0078] Specifically, after determining the length of the first telescopic portion 3121 extending from the first telescopic hole 3122a, the first telescopic fixing piece 3123 is screwed, and one end of the first telescopic fixing piece 3123 extends from the first connecting hole 3122c into the first telescopic hole 3122a and abuts against the outer surface of the first telescopic portion 3121 located in the first telescopic hole 3122a, thereby achieving the effect of fixing the length of the first connecting piece 312.

[0079] Similarly, after determining the length of the second telescopic part extending from the second telescopic hole, the second telescopic fixing piece is screwed so that one end of the second telescopic fixing piece extends from the second connecting hole into the second telescopic hole and is pressed against the outer surface of the second telescopic part located in the second telescopic hole, thereby achieving the effect of fixing the length of the second connecting piece 322.

[0080] like Figure 3 As shown, a first buffer pad 3131 is provided on a side of the first support member 313 in contact with the periorbital area; a second buffer pad 3231 is provided on a side of the second support member 323 in contact with the periorbital area.

[0081] Specifically, since the first support member 313 and the second support member 323 are in direct contact with the user's skin around the eyes, the provision of the first buffer pad 3131 and the second buffer pad 3231 can reduce the stress concentration of the first support member 313 and the second support member 323 on the user's skin around the eyes, thereby preventing damage to the user's skin around the eyes.

[0082] like Figure 3 As shown, a fixing groove is provided on one side of the first support member 313 close to the second support member 323 , and a fixing block is provided on one side of the second support member 323 close to the first support member 313 , and the fixing block is slidably provided in the fixing groove.

[0083] Specifically, the first support member 313 and the second support member 323 are semicircular in shape, and the first support member 313 and the second support member 323 are detachably connected via a fixing groove and a fixing block.

[0084] For example, both ends of the first support member 313 are provided with fixing grooves, and both ends of the second support member 323 are provided with fixing blocks. The fixing grooves and the fixing blocks are slidably connected to achieve the installation of the first support member 313 and the second support member 323.

[0085] It should be noted that the two ends of the first support member 313 can also be respectively provided with a fixing groove and a fixing block, or the two ends of the first support member 313 can also be provided with a fixing block at the same time. Similarly, the two ends of the second support member 323 are slidably matched with the first support fixing member 311, and the two ends of the second support member 323 can be respectively provided with a fixing block and a fixing groove, or the two ends of the second support member 323 can be provided with a fixing groove at the same time.

[0086] Furthermore, the fixing grooves on the first support member 313 and the second support member 323 are both dovetail grooves, and the fixing blocks on the first support member 313 and the second support member 323 are both dovetail blocks slidably connected to the dovetail grooves.

[0087] The slidable connection between the dovetail groove and the dovetail block can provide high-precision guidance. The dovetail block can be tightly embedded in the dovetail groove. This shape allows the dovetail block to move only in a specific direction in the dovetail groove. In addition, the sides of the dovetail groove and the dovetail block fit tightly, limiting the degrees of freedom in other directions, thereby ensuring the linearity and accuracy of the movement.

[0088] The sliding direction of the slidable connection between the first support member 313 and the second support member 323 is consistent with the sliding direction of the slidable connection between the first support fixing member 311 and the second support fixing member 321 .

[0089] The slidable connection between the first support member 313 and the second support member 323 cooperates with the slidable connection between the first support fixing member 311 and the second support fixing member 321, thereby increasing the stability of the connection between the first periocular support assembly 31 and the second periocular support assembly 32 and the stability of the periocular support using the periocular support device 3.

[0090] like Figure 8 As shown, a method for self-testing intraocular pressure is applied to any of the above-mentioned tonometers that are convenient for patients to self-test, wherein the tonometer that is convenient for patients to self-test comprises a tonometer body 1, a probe head 2 and a periocular support device 3, wherein the probe head 2 is arranged on the tonometer body 1; the periocular support device 3 is retractably arranged on the tonometer body 1, and the periocular support device 3 is arranged on the tonometer body 1 around the probe head 2, and the periocular support device 3 is used to support the periphery of the eye.

[0091] The method comprises:

[0092] S100, adjusting the length of the eye periorbital support device 3 so that the distance from the probe head 2 to the eye to be tested is within the testing range.

[0093] Specifically, before performing intraocular pressure testing on the eye to be tested, it is necessary to first adjust the distance from the probe head 2 to the eye by adjusting the length of the periocular support device 3 to prevent the distance from the probe head 2 to the eye to be tested from being too short and causing damage to the eye, or the distance from the probe head 2 to the eye to be tested from being too long and affecting the accuracy of intraocular pressure testing.

[0094] The detection range can be determined through multiple experiments. After the detection range is determined, a detection range mark can be engraved on the first accommodating portion 3122 or the second accommodating portion, and an indicator mark can be set on the outer surface of the probe head 2. When the indicator mark is within the detection range mark, it means that the distance from the probe head 2 to the eye to be detected is within the detection range.

[0095] S200 , placing the periorbital support device 3 against the periorbital area of ​​the eye to be tested, and starting the tonometer body 1 .

[0096] Specifically, the probe head 2 is located at the center of the through hole. When the periocular support device 3 is against the periorbital area of ​​the eye to be tested, the probe head 2 can be directly opposite the eye to be tested. Then, pressing the start switch on the tonometer body 1 can start the probe head 2 to perform intraocular pressure detection on the eye to be tested.

[0097] In summary, a tonometer that is convenient for patients to self-test includes a tonometer body 1, a probe head 2 and a periocular support device 3; the probe head 2 is arranged on the tonometer body 1; the periocular support device 3 is retractably arranged on the tonometer body 1, and the periocular support device 3 is arranged on the tonometer body 1 around the probe head 2, and the periocular support device 3 is used to support the periphery of the eye.

[0098] When the user uses the tonometer that is convenient for patients to measure intraocular pressure by themselves, the periocular support device 3 is placed against the periorbital area of ​​the eye to be tested. At this time, the probe head 2 in the periocular support device 3 can be directly opposite the eye to be tested, so that the eye to be tested can be conveniently tested. Due to the support of the periocular area by the periocular support device 3, the patient can conveniently and safely keep the probe head 2 at a suitable distance from the eye to be tested, so that the patient can independently operate to measure intraocular pressure. At the same time, due to the retractable nature of the periocular support device 3, before performing intraocular pressure testing on the eye to be tested, the distance from the probe head 2 to the eye can be adjusted by adjusting the length of the periocular support device 3 to prevent the distance from the probe head 2 to the eye to be tested from being too short to cause damage to the eye or the distance from the probe head 2 to the eye to be tested from being too long to affect the accuracy of intraocular pressure testing, thereby solving the problem that the existing tonometer cannot be used independently by patients for intraocular pressure testing.
