Intraocular pressure measuring device

An intraocular pressure measuring device, comprising an intraocular pressure sensor (1), a shooting module (2), and a shooting element (3), wherein

• the intraocular pressure sensor (1) is provided with a Fabry-Perot cavity;
• the shooting module (2) comprises a housing (21), an optical path assembly (22) arranged in the housing (21), and a light source (23) arranged outside the housing (21);
• the housing (21) is provided with a shooting hole (211);
• the light emitted by the light source (23) is transmitted to the Fabry-Perot cavity after passing through the optical path assembly (22), and forms an interference pattern;
• the shooting element (3) comprises a lens (31);
• the shooting hole (211) is suitable for cooperating with the lens (31) to obtain the interference pattern through the shooting element (3);
• the optical path assembly (22) comprises a beam splitter cube (221) and a plano-convex lens (222) sequentially arranged in the shooting hole (211);
• the optical path assembly (22) further comprises a narrowband filter (223) arranged between the light source (23) and the beam splitter cube (221);
• the intraocular pressure sensor (1) comprises a sensor body (11) and a bracket (12) connected to the sensor body (11);
• the bracket (12) comprises a mounting end (121) and a fixing end (122) connected to the mounting end (121);
• the fixing end (122) comprises a wide section (1221), a gradient section (1222), and a narrow section (1223) connected sequentially, and the widths of the wide section (1221), the gradient section (1222) and the narrow section (1223) decrease in sequence;
• the bracket (12) is provided with a drainage groove (123);
• the drainage groove (123) comprises a first groove-shaped structure (1231) longitudinally arranged along the bracket (12);
• and
• the drainage groove (123) further comprises a second groove-shaped structure (1232) obliquely arranged on the wide section (1221), and the second groove-shaped structure (1232) is connected to the first groove-shaped structure (1231).
