Description

TECHNICAL FIELD

BACKGROUND

[0002] The fluid collection box in the ophthalmic surgery box generally refers to a medical device used to collect the liquid on the eye of a patient during an ophthalmic surgery. It plays a key auxiliary role in the surgery process, can keep the surgical area clean, prevent the liquid from contaminating the operating table or surgical instruments, and also facilitates the collection and processing of the liquid after the surgery.

[0003] The fluid collection box needs liquid level measurement to determine the internal liquid level. The mainstream liquid level detection components currently include pressure water level detection components, optical liquid level detection components, float liquid level detection components, and resistance type liquid level detection components. These detection components achieve liquid level detection through different physical principles. For example, the pressure detection component determines the liquid level height by measuring the hydrostatic pressure, the optical detection component utilizes the refraction or reflection characteristics of light, and the float detection component works on the principle of buoyancy.

[0004] In actual application, most traditional liquid level detection components need to directly contact the measured liquid to achieve accurate measurement. This contact type measurement method not only increases the structural complexity of the container component, but also may cause liquid contamination due to the direct contact between the detection component and the liquid, which is particularly prominent in the medical, food processing and other fields with strict hygiene requirements. In addition, commercial standardized liquid level detection component products usually adopt fixed structure and interface design, which is difficult to flexibly adjust according to the needs of different application scenarios, resulting in limited applicability in special container components or complex environments. SUMMARY

[0005] The purpose of the present application is to provide a surgical fluid collection box liquid level measurement device to alleviate the technical problems in the prior art that contact type measurement of the liquid level height in the fluid collection box increases the volume of the container and also contaminates the liquid.

[0023] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0024] The surgical effusion box liquid level measuring device provided by the embodiment includes: a container member 100 for containing effusion from a surgical procedure; a light source member 200 for emitting a light beam to the container member 100, and the light beam is refracted or totally reflected at the side wall of the container member 100 according to the liquid level in the container member 100; and a detection member 300 for detecting the light beam totally reflected at the inner wall of the container member 100 or detecting the light beam passing through the container member 100.

[0025] It should be noted that the container member 100 is specifically provided with polymethyl methacrylate plastic material, the refractive index is 1.49, the refractive index of air is 1, and the refractive index of water in the container member 100 is 1.33, so that in the case that the incident angle is greater than the critical angle, the light beam is totally reflected in the part of the container without liquid, the detection member 300 detects the light beam after total reflection, and according to the light beam energy distribution detected by the detection member 300, the light beam is refracted in the part of the container with liquid, and the refracted light beam cannot be detected by the detection member 300, so that the liquid level height is determined.

[0026] In addition, the outer wall of the container member 100 is provided with a light shielding member in the light beam non-irradiation area, and the light shielding member is specifically provided with a silk screen layer, which can effectively reduce the background noise and improve the signal-to-noise ratio of the liquid and the non-liquid.

[0027] In an optional embodiment, as shown in Figure 5 one of the inner walls of the container member 100 is inwardly convex to form a convex wall 111; when the light source member 200 emits a light beam to the convex wall, the light beam is refracted or totally reflected at the convex wall 111; when the light source member 200 emits a light beam to the flat surface, the light beam is refracted inside the container member 100 or passes through the container member 100; the outer wall of the container member 100 is provided with a groove 112 corresponding to the position of the convex wall 111, and the user determines the position of the convex wall 111 through the groove 112.

[0028] The light beam emitted by the light source member 200 can be irradiated on the convex wall 111 for liquid level testing, or irradiated on the flat surface for liquid level testing, so that the container member 100 with the convex wall 111 structure can be applied to different models of the super-lathering and glass cutting integrated machine.

[0029] In addition, the light source member 200 and the detection member 300 are installed on the super-lathering and glass cutting integrated machine, and the detection member 300 can be provided with two sensors, i.e. the first sensor 310 and the second sensor 320. The first sensor 310 is arranged at a position on the same side as the light source member 200, and the second sensor 320 is arranged at a position on the other side wall connected to the irradiated side wall. Through the feedback of the two sensors, the specific structure of the container member 100 is determined. For example, when the first sensor 310 can detect the light beam and the second sensor 320 cannot detect the light beam, it means that the light beam emitted by the light source member 200 is irradiated on the convex wall 111. Similarly, when the second sensor 320 can detect the light beam and the first sensor 310 cannot detect the light beam, it means that the light beam emitted by the light source member 200 is irradiated on the flat surface.

[0030] According to the type of the detection member 300, various detection architectures can be provided. For example, the detection member 300 includes a plurality of first sensors 310, which are arranged as reflective point sensors. The first sensors 310 have first detection areas, and the plurality of first sensors 310 are arranged in parallel along the depth direction of the container member 100 to form a dot matrix detection area. The plurality of first detection areas cover the depth dimension of the container member 100. When there is no liquid in the container member 100, each first detection area can detect the light beam. When there is half liquid in the container member 100, half of the first detection areas can detect the light beam, and the other half of the first detection areas cannot detect the light beam. According to whether the plurality of detection areas can detect the light beam energy, the liquid level height is determined.

[0031] For another example, the detection member 300 includes a second sensor 320, which is arranged as a line CMOS sensor. The second sensor 320 has a second detection area, and the second detection area can cover the depth dimension of the container member 100. When there is no liquid in the container member 100, all positions of the second detection area can detect the light beam. When there is half liquid in the container member 100, half of the second detection areas can detect the light beam, and the other half of the second detection areas cannot detect the light beam. According to whether the second detection area can detect the light beam energy, the liquid level height is determined.

[0032] For example, the detection member 300 comprises a first sensor 310 and a second sensor 320, the first sensor 310 is arranged as a reflective point sensor, and the second sensor 320 is arranged as a line CMOS sensor; the first sensor 310 is arranged on the opposite sides of the second sensor 320, the first sensor 310 has a first detection area, and the second sensor 320 has a second detection area, and the combined area of the first detection area and the second detection area covers the depth dimension of the container member 100.

[0033] In addition, the light source member 200 can select a dot matrix LED light source or a line LED light source according to actual conditions.

[0034] Based on the above, the arrangement position of the light source member 200 and the detection member 300 can be adjusted according to actual conditions, such as Example One: As shown in Figure 1 , Figure 2 , the light source member 200 and the detection member 300 are arranged on the same side of the container member 100, the light beam emitted by the light source member 200 is irradiated on the convex wall 111, and the liquid level height in the container member 100 is determined according to the detection of the detection member 300.

[0035] Example Two: As shown in Figure 3 , Figure 4 , the container member 100 has a first side wall and a second side wall connected to each other; the light source member 200 is arranged on one side of the first side wall, and the detection member 300 is arranged on one side of the second side wall; the light beam emitted by the light source member 200 is irradiated on the flat surface, and the liquid level height in the container member 100 is determined according to the detection of the detection member 300.

[0036] In an optional embodiment, as shown in Figure 7 , Figure 8 , a prism can be installed on the side wall of the container member 100, and the specific implementation is as follows: the container member 100 comprises a first container 110 and a second container 120; the first container 110 and the second container 120 are connected to each other, the first container 110 is provided with a first prism 410 on the side away from the second container 120, and the second container 120 is provided with a second prism 420 on the side away from the first container 110; the light source member 200 comprises a first light source 210 and a second light source 220, and the detection member 300 comprises a first sensor 310 and a second sensor 320; the first light source 210 emits a light beam to the first prism 410, and the first sensor 310 can detect the light beam that has undergone total reflection in the first prism 410; the second light source 220 emits a light beam to the second prism 420, and the second sensor 320 can detect the light beam that has undergone total reflection in the second prism 420.

[0037] When there is no liquid in the first container 110, the light beams emitted by the first light source 210 are totally reflected in the first prism 410, and the detection area of the first sensor 310 detects all the light beams. The first sensor 310 generates a signal indicating that there is no liquid in the first container 110. Similarly, when there is no liquid in the second container 120, the light beams emitted by the second light source 220 are totally reflected in the second prism 420, and the detection area of the second sensor 320 detects all the light beams. The second sensor 320 generates a signal indicating that there is no liquid in the second container 120.

[0038] When the first container 110 is filled with liquid, the light beams emitted by the first light source 210 are refracted at the interface between the side wall of the first container 110 and the first prism 410. The first sensor 310 cannot detect the light beams, and generates a signal indicating that the first container 110 is filled with liquid. When the second container 120 is filled with liquid, the light beams emitted by the second light source 220 are refracted at the interface between the side wall of the second container 120 and the second prism 420. The second sensor 320 cannot detect the light beams, and generates a signal indicating that the second container 120 is filled with liquid.

[0039] When the first container 110 has partial liquid, part of the light beams emitted by the first light source 210 are refracted at the interface between the side wall of the liquid part of the first container 110 and the first prism 410, and the other part of the light beams emitted by the first light source 210 are totally reflected in the first prism 410. The first sensor 310 detects part of the light beams and generates a liquid level signal according to the detected energy distribution. The same applies when the second container 120 has partial liquid.

[0040] It should be noted that, Figure 1 、 2 , 3, 4, and 7 are top-down viewing angles.

[0041] The surgical effusion box liquid level measuring device provided in the embodiment utilizes the principle of reflection and refraction of light at different medium interfaces to determine the liquid level height by detecting the energy distribution of the light beams. The device has the following significant technical effects: 1. Non-contact continuous liquid surface testing: The device uses a non-contact optical measurement method, which avoids the cross-contamination problem that may be caused by traditional contact sensors. This non-contact design is particularly suitable for medical environments where high sterility is required.

[0042] By continuously monitoring the energy distribution of the light beams, real-time and continuous detection of the liquid level can be achieved, improving the measurement accuracy and response speed.

[0043] 2. Simple structure, easy to install: The device is composed of three parts: container component 100, light source component 200, and detection component 300. The overall structure is compact and easy to integrate into existing machines.

[0044] During installation, no complex modifications are required for the container component 100. Simply fix the light source component 200 and the detection component 300 to the side wall of the container component 100, greatly simplifying the installation steps.

[0045] 3. Does not affect the volume of the container component 100: Due to the use of non-contact measurement technology, the device does not increase the volume of the container component 100. Traditional contact sensors often require additional mechanical structures inside or outside the container, which occupies a certain space.

[0046] The light source component 200 and the detection component 300 of the device can be installed closely to the outer wall of the container component 100, without occupying additional space, maintaining the original volume and shape of the container component 100.

[0047] 4. Suitable for various scenarios: The device is not only suitable for surgical effusion boxes, but also can be applied to other medical devices or industrial devices that require liquid level monitoring.

[0048] Due to its non-contact design, the device can adapt to different types of liquids such as blood, irrigation fluid, and physiological saline, and has no special requirements for liquid composition, with a wide range of applications.

[0049] 5. High sensitivity and high precision: By precisely controlling the incident angle of the light source and the position of the detection component 300, high-precision measurement of the liquid level height can be achieved. Even with small changes in liquid level, changes in light beam energy distribution can be accurately detected.

[0050] The device can quickly respond to changes in liquid level, providing real-time liquid level data, which helps to timely adjust the liquid management strategy during surgery.

[0051] 6. Reliability and stability: The device uses optical principles for measurement and is not affected by electromagnetic interference, with high stability and reliability.

[0052] Through reasonable signal processing and calibration mechanisms, the accuracy of measurement results can be further improved, ensuring stable operation under various environmental conditions.

[0053] In summary, the surgical effusion box liquid level measuring device provided by the embodiment realizes continuous and high-precision detection of the liquid level through a non-contact optical measurement method, has the advantages of simple structure, convenient installation, no influence on the volume of the container, wide application range and the like, effectively solves the problems existing in the prior art, and provides a reliable liquid level monitoring solution for the medical and industrial fields.
