[0032] The utility model provides an ophthalmic intraocular pressure testing device. Figure 1-Figure 6 As shown, the ophthalmic intraocular pressure testing device comprises:

[0033] A handheld host 100, which is composed of a handle 110 and a testing unit 120;

[0034] The support member 200 includes a clamping strip 210, a carrying plate 220, a pressing plate 230 and an outer supporting member 240. The handle 110 is provided with a clamping slot, the clamping strip 210 is clamped in the clamping slot, the carrying plate 220 and the pressing plate 230 are respectively held against the handle 110 and the testing part 120, and the outer supporting member 240 is connected to the carrying plate 220;

[0035] In this embodiment, the handheld host 100 is mainly composed of a handle 110 and a test unit 120. The test unit 120 is provided with a support column 130 and a test head 140. The internal structure of the test unit 120 and the support column 130 and the test head 140 are all prior art equipment. The test unit 120 adopts a non-contact test principle. The support column 130 will be supported on the side of the patient's eye. The test head 140 is aimed at the patient's eye and emits air pulses to the patient's eye to measure intraocular pressure data.

[0036] The handle 110 is provided with a power supply component inside, and the handle 110 is provided with a slot adapted to the card strip 210, the support member 200 is clamped on the handle 110 as a whole by clamping, the top of the carrying plate 220 is abutted on the test part 120, and the pressing plate 230 is abutted on the handle 110;

[0037] During the test, the supporting column 130 is supported above the patient's eyes, and the supporting member 200 is pressed against the patient's cheekbone or maxilla. The function of the supporting member 200 is to help the handheld host 130 obtain more support points, so that the test head 140 can be more easily aligned with the eyes, avoiding the shaking during the hand-held process causing the alignment process to be unstable, thereby causing inaccurate measurement data. The supporting member 200 adopts a snap-on connection method. After the user becomes proficient in the technology, the supporting member 200 can be removed, and the handheld host 100 can be used independently to perform intraocular pressure testing.

[0038] As a preferred implementation in this embodiment, the clamping strip 210 is arranged on one side of the carrying plate 220, the outer support 240 is arranged on the side of the carrying plate 220 away from the clamping strip 210, and the pressing plate 230 is connected to the end surface of the carrying plate 220 away from the testing part 120. When the clamping strip 210 is clamped on the handle 110, the top of the carrying plate 220 will be against the bottom of the testing part 120; the side of the carrying plate 220 provided with the clamping strip 210 is attached to the side wall of the handle 110;

[0039] When the corners of the handle 110 described in the present application are rounded, the supporting plate 220 and the pressing plate 230 are also provided with corresponding arc structures to fit the side walls of the handle 110.

[0040] The top of the bearing plate 220 is an arc-shaped structure adapted to the bottom of the test part 120. The bearing plate 220 is mainly used for the purpose of clamping and receiving. By using the bearing plate 220 itself, the clamping strip 210 and the pressing plate 230 to form a multi-point support structure, the stability of the connection between the support member 200 and the handle 110 during use is improved;

[0041] The outer support 240 includes a base 241, an extension rod 242 and a support plate 243. One end of the extension rod 242 is arranged inside the base 241, and the other end of the extension rod 242 extends out of the base 241. The support plate 243 is connected to the end of the extension rod 242 extending out of the base 241. The support plate 243 is responsible for contacting the patient's face. The extension rod 242 is used to realize the elastic connection between the support plate 243 and the base 241, so as to alleviate the discomfort caused by the pressure action to the patient to the greatest extent.

[0042] As a preferred implementation in this embodiment, a mounting hole 2411 for accommodating the extension rod 242 is provided on the base 241; a first spring 2412 and a damping ring 2413 are provided in the mounting hole 2411, and the damping ring 2413 is arranged on a side of the mounting hole 2411 close to the hole opening; the end surface of the base 241 away from the mounting hole 2411 is connected to the bearing plate 220;

[0043] The extension rod 242 is inserted into the mounting hole 2411, and a limiting ring 2421 is provided on the portion of the extension rod 242 inserted into the mounting hole 2411. One end of the first spring 2412 is connected to the end of the mounting hole 2411 away from the orifice, and the other end is connected to the limiting ring 2421. The first spring 2412 holds the limiting ring 2421 against the end of the damping ring 2413 away from the orifice. Here, the damping ring 2413 is equivalent to a limiter to prevent the limiting ring 2421 from continuing to move forward. The side of the extension rod 242 away from the first spring 2412 passes through the damping ring 2413 and finally extends from the orifice of the mounting hole 2411 to the outside of the base 241; when the support plate 243 is compressed, the extension rod 242 moves toward the side of the first spring 2412 and retracts into the base 241. When the pressure is reduced, the first spring 2412 will push the extension rod 242 out again, thereby ensuring that the extension rod 242 has elasticity and can maintain a fixing effect.

[0044] The outer wall of the extension rod 242 located inside the damping ring 2413 is a frosted structure. The damping ring 2413 is made of rubber and has a diameter slightly smaller than the rod diameter of the extension rod 242. The damping ring 2413 is used to enhance the resistance of the extension rod 242 during movement. This design allows the initial driving friction to be larger, and it is not easy to move easily after stabilization, thereby providing stability during the fixing process.

[0045] As a preferred implementation in this embodiment, the support plate 243 includes a fitting block 2431 and a connecting plate 2432. Both the connecting plate 2432 and the fitting block 2431 are arc-shaped structures, which are convenient for better fitting the facial contour. The fitting block 2431 adopts soft rubber material to reduce the pressure on the face. The contact plane between the fitting block 2431 and the face is also an arc-shaped structure, which further enhances the fitting effect with the facial contour and reduces the discomfort caused by facial pressure.
