[0049] In this embodiment, implementation methods of the present technology and effects produced by the present technology are described.

[0050] In the example description of the present invention, "up, down, left, and right" are mentioned to indicate the orientation. It should be noted that the device of the present invention does not have to be implemented in such an orientation. The use of up, down, left, and right to describe is only for easier understanding by those skilled in the art. For example, the upper support seat and the lower support seat described in the present invention do not necessarily have to have the upper support seat structure component arranged at the top and the lower support seat structure component arranged at the bottom in order to implement the present invention. Instead, the upper and lower positions can be reversed, and the lower support seat of the structure described in the present invention can be arranged above the upper support seat. The present invention can still be implemented and the effects described in the present invention can be obtained.

[0051] The present invention also has the terms "first, second" to indicate serial numbers, such as "first concave surface, first convex platform". It should be noted that these terms to indicate serial numbers do not refer to the order of installation of these components of the present invention, nor do they refer to other understandings such as important procedures between these components. Instead, when naming, the components are named according to their functions, forms, and common standards. "First, second" are added in front only to better distinguish the components, facilitate reading and understanding, and avoid confusion.

[0052] The term "external environment" is used in the present invention, and is defined as follows:

[0053] 1. Relative to the support base, the outside world refers to the part beyond the support base body; the light source device, and the closed space formed by the connection between the light source part and the support base, also belong to the outside world for the support base.

[0054] 2. Relative to the closed space, the outside world refers to the part beyond the whole formed by the connection between the light source part and the support seat, such as the outer surface of the outer shell, the lower surface of the lower support seat, and the outer side surface of the support seat, all of which belong to the outside of the closed space.

[0055] The technical term "detachable connection" is also used in the present invention. Detachable connection means that the two parts belong to different components, but they have a good adaptation structure, and one part can be easily installed on the other part to form a whole with specific functions; or one part can be easily removed from the other part, and users without professional training can also install and remove it after simple guidance in the instructions; or during the installation or removal process, the structure can be left intact or only the special structure for preventing secondary use can be destroyed; it can be installed or removed without using tools or with very simple tools.

[0056] The lens assembly described in the present invention may also be referred to as an optical lens; the microscope lens described in the present invention may also be referred to as a microscope, or a lens of a microscope.

[0057] The present invention comprises two parts, the first part is the light source part, and the second part is the body fluid sample placement and optical lens component part.

[0058] The second part (body fluid sample placement and optical lens component part) is at the lower part, the first part (the light source part) is at the upper part, and the light source part is encapsulated in the outer shell.

[0059] The first part and the second part are detachable. The two parts can be easily separated during use, or they can be easily buckled together. Because when placing body fluids, the body fluids need to be placed on the second part after being separated, and then the first part is buckled on the second part to provide light source for the second part.

[0060] In one example, the first part of the present invention (basically equivalent to the size of the shell) is 20mm high, 30mm long, and 18mm wide; the second part of the present invention is 5mm high, 30mm long, and 18mm wide.

[0061] Example 1:

[0062] The lens assembly is integrally formed, with a glass slide for placing a body fluid sample on one side and a microscope lens for observing the body fluid on the other side. The microscope lens is located below the glass slide, specifically, the glass slide is located above and the microscope lens is located below.

[0063] Because one of the preferred embodiments of the present invention is to observe through the front camera of the smartphone below. Since the main observation object of the present invention is body fluid (including semen, sweat, urine, etc.), this type of substance has the characteristics of fluidity, but also has a certain liquid tension (so that the fluidity is not large, and when it is dripped onto a certain plane, it is easy to gather into a water drop shape through liquid tension without spreading), so when observing, the best or most commonly used way is to drop it on a roughly horizontal stage. For the present invention, the body fluid is dripped on a glass slide. A glass slide is a glass or quartz plate used to place things when observing things with a microscope. When making samples, cells or tissue slices are placed on a glass slide for observation. The glass slide of the present invention also acts as a transparent sheet for placing things, but the material of the present invention is not limited to the use of glass or quartz materials. Instead, a better use example of the present invention is to use optical plastics, which are not easy to break, easy to process, and low in cost. The present invention is still named "glass slide" according to the function and the custom in the field.

[0064] Therefore, the slide is set on top and kept as horizontal as possible when in use, with the middle of the upper surface of the slide. Of course, it is not necessarily in the middle, but at least it is directly above the microscope lens for dripping body fluid specimens.

[0065] The entire optical lens is made of transparent optical plastic. Optical plastics are generally used in optical instruments with large batches, and are used to manufacture optical substrates, lenses, contact lenses, organic optical fibers, etc. The optical plastics that have been applied mainly include transparent plastics.

[0066] Plastic medium used to manufacture various optical parts. Compared with optical glass, optical plastics have advantages such as good plastic molding process characteristics, light weight, and low cost. Optical plastics are increasingly used to manufacture optical parts (including simple camera lenses), especially some special optical parts. For example, the following materials can be used as optical plastics:

[0067] Polymethyl methacrylate (PMMA): commonly known as organic glass, is the plastic with the best optical properties. There are also polystyrene (PS), polycarbonate (PC), styrene acrylonitrile often abbreviated as AS and SAN, styrene-methyl methacrylate copolymer (MS), transparent polyamide, etc.

[0068] The optical lens is a circular thin sheet with an overall thickness of about 1.5 mm and an overall diameter of about 10 mm. The glass slide and the microscope lens are integrally formed. The center of the bottom surface of the glass slide is the microscope lens, which is a hemispherical lens protruding from the bottom center of the glass slide. After the microscope lens protrudes, it extends into the small hole of the lower support (the small hole mentioned here is an observation hole, which is called a small hole because of its extremely small diameter). The aperture of the small hole is about 0.1 to 1 mm. The center of the optical lens is the microscope lens, and the microscope lens is aligned with the small hole. By aligning the mobile phone camera with the small hole, observation can be carried out. The diameter of the microscope lens is also less than 1 mm, and the height is less than 1 mm.

[0069] Example 2:

[0070] Install the support base of the lens assembly.

[0071] On the side of the support base corresponding to the microscope lens (refer to the figure, the microscope lens is at the bottom, so the side corresponding to the microscope lens is at the bottom of the support base), an observation hole equivalent to the outer diameter of the microscope lens and connected to the outside world is opened; and the microscope lens is embedded in the observation hole.

[0072] On the opposite side of the support base corresponding to the microscope head, (refer to the attached Figure 1-2 , the microscope head is at the bottom, so the opposite side corresponding to the microscope head, that is, on the upper side of the support seat, specifically the upper surface of the upper support seat), is provided with a light-transmitting hole coaxial with the observation hole; and a body fluid sample dripping hole, as well as an air-permeable hole that penetrates the dripping hole and the surface of the glass slide. The dripping hole and the air-permeable hole are both connected to the outside world. Of course, after the light source part is buckled on the support seat, the dripping hole and the air-permeable hole are actually connected to the closed space formed.

[0073] The light-transmitting hole is equipped with a transparent material that isolates the glass slide from the outside world by air (for the sake of ease of description, the transparent material here is named: transparent partition). That is to say, the top of the glass slide can be seen, but the air is isolated, and of course the liquid is also isolated. The purpose is to direct the light source that is transmitted through the light source part to the glass slide of the lens assembly through the light-transmitting hole, but the body fluid added to the glass slide cannot overflow from the light-transmitting hole.

[0074] One example is: a transparent partition is installed in the light-transmitting hole, and the light-transmitting hole is filled with the transparent partition, or is in a semi-filled state.

[0075] One example is: a transparent partition is installed below the light-transmitting hole and between the glass slide, and the transparent partition is used to form an air and liquid barrier between the light-transmitting hole and the glass slide.

[0076] The support seat is composed of an upper support seat and a lower support seat. The upper support seat and the lower support seat are both thin plates and are fitted together. The lens assembly is clamped between the upper support seat and the lower support seat. The lens assembly is encapsulated in the support seat. The support seat is generally a rectangular thin plate structure.

[0077] In one embodiment, a first mounting hole adapted to the shape of the lens assembly is provided below the upper support seat, and the lens assembly is fixed in the first mounting hole. Then, the lower support seat and the upper support seat are clamped to position the lens assembly so that the lens assembly is clamped in the support seat and is shielded and surrounded.

[0078] In one embodiment, a first mounting hole adapted to the shape of the lens assembly is provided on the lower support seat, and the lens assembly is fixed in the first mounting hole. Then, the lower support seat and the upper support seat are clamped to position the lens assembly so that the lens assembly is clamped in the support seat and is shielded and surrounded.

[0079] A preferred embodiment is that the optical lens is sandwiched between the upper surface of the lower support and the lower surface of the upper support, and both the upper surface of the lower support and the lower surface of the upper support are provided with a recess for mounting the optical lens (the upper surface of the lower support is the first mounting hole for the optical lens, and the lower surface of the upper support is the second mounting hole for the optical lens), and the diameters of the first mounting hole and the second mounting hole are the same. About two-thirds of the thickness of the lens assembly is sunken in the first mounting hole, and about one-third is sunken in the second mounting hole.

[0080] The light transmission hole and the observation hole are located at the center of the first mounting hole and the second mounting hole and are concentric.

[0081] Example 3:

[0082] The overall shape of the lower bearing seat is a rectangular plate.

[0083] The lower support is a thin plate made of shading material, which is black plastic. There is also a step hole on the upper surface of the thin plate. The upper section is a large hole (that is, the first mounting hole of the lens assembly), and the optical lens assembly is mainly installed in the first mounting hole of the lens assembly; the lower section of the step hole is a small hole, which is an observation hole.

[0084] Therefore, the main function of the lower support is to install the optical lens. In this example, the lower support is 30 mm long, 15 mm wide, and 2 mm thick, wherein the depth of the first mounting hole of the optical lens is greater than or equal to 1.5 mm, and the depth of the observation hole (lower small hole) is 0.3 mm.

[0085] The bottom surface of the lower support seat is a plane, and only one observation hole (small hole) is visible. At the same time, the first boss of the upper support seat forms the same plane as the lower surface of the lower support seat. Therefore, the lower surface of the support seat of the present invention is generally a plane, and only one observation hole is visible.

[0086] The upper support seat is a thin plate made of a light-shielding material, and the light-shielding material is black plastic. The overall shape of the upper support seat is a rectangular plate with two upper and lower surfaces.

[0087] Among them, the structure seen on the upper surface: three holes (dripping hole, light-transmitting hole, and air-permeable hole) are provided, the dripping hole, the light-transmitting hole, and the air-permeable hole are arranged in order, the middle hole is the light-transmitting hole, and the two sides of the light-transmitting hole are the dripping hole and the air-permeable hole respectively, wherein the axis of the light-transmitting hole is perpendicular to the plane of the glass slide (of course the plane of the glass slide is parallel to the lower surface of the lower support and parallel to the upper surface of the upper support), and the axes of the dripping hole, the light-transmitting hole, and the air-permeable hole are arranged side by side on the same straight line.

[0088] The purpose of the air hole (also called siphon hole) is to circulate air. When body fluid drips from the dripping hole, if there is no siphon effect of air, or drainage, if air blockage is formed, it is difficult for the body fluid to flow onto the surface of the slide. Therefore, an air hole is opened. When body fluid drips from the dripping hole, the body fluid is guided to the top of the slide through the air hole. Therefore, in this example, the air hole is required to be connected with the dripping hole and the surface of the slide.

[0089] However, the body fluid should only flow into the surface of the glass slide after dripping from the dripping hole, and not overflow into other locations (such as overflowing into the mounting hole, the interlayer between the lower support and the upper support, which may contaminate the microscope lens and leave no body fluid sample on the glass slide). Therefore, the surface of the glass slide is only connected with the dripping hole and the air hole, and is air-isolated from other components, including the light-transmitting hole.

[0090] The light-transmitting hole is aligned with the middle of the optical lens, and the drip hole and the air-permeable hole are respectively connected to the left and right of the optical lens.

[0091] The dropping hole is a fan-shaped hole with a radius of 2 mm (that is, it is not a circle, but only half of a circle), and the missing half is close to the light-transmitting hole. The wall of the straight part of the fan-shaped hole is an inclined surface, which is inclined downward toward the light-transmitting hole, so that it is easier for the body fluid to drip into the hole and flow smoothly onto the slide along the dropping hole.

[0092] The upper part of the light-transmitting hole is a trumpet-shaped hole, the maximum inner diameter of the trumpet-shaped hole is 2-3 mm, and the inner diameter of the lower part of the light-transmitting hole is 1-2 mm. The diameter of the air-permeable hole is 1-2 mm.

[0093] The overall shape of the upper support is a rectangular plate with two surfaces, the upper and lower surfaces. The structure seen on the lower surface is:

[0094] A first concave surface for mounting a lower support is provided under the upper support, and a first boss is formed on the outer edge of the first concave surface. After the lower support is mounted on the first concave surface, the lens is encapsulated. The lower support is clamped by the first boss. Therefore, the rest of the lens assembly excluding the observation hole, the drip hole, the light-transmitting hole and the air-permeable hole is surrounded by the first boss of the support seat to block external light.

[0095] The first boss and the lower surface of the lower support seat form the same plane, the recessed depth of the first concave surface is equivalent to the thickness of the lower support seat, and the total length and total width are also equivalent to the length and width of the lower support seat.

[0096] Example 4:

[0097] A light source part is arranged above the support seat, corresponding to the light transmission hole and used to provide a fixed illumination light source for the light transmission hole, and the light source part is detachably connected to the support seat. After the light source part is connected to the support seat, a closed space isolated from external light is formed above the light transmission hole, the drip hole, and the air hole.

[0098] The light source part is composed of a shell that isolates external light and a fixed lighting source installed in the shell; a mutual adaptation structure is arranged below the light source part and above the support seat to form the closed space and enable the light source part and the support seat to be detachably connected.

[0099] One of the preferred mutually adaptable structures is: a circle of second bosses is arranged below the outer shell and along the edge of the outer shell, and a circle of annular bosses is arranged above the support seat. The inner wall of the second boss is adapted to the outer wall of the annular boss, and the outer shell and the support seat are clamped by the friction force between the outer wall of the annular boss and the inner wall of the second boss.

[0100] The mutually adaptable structure can also be: double-sided adhesive, so that a circle of second bosses are set below the shell and along the edge of the shell, and the top of the support seat is a plane, and the second boss is bonded to the plane above the support seat by double-sided adhesive.

[0101] The mutual adaptation structure can also be in many other ways, just snap the shell and the support seat together. But it must form a closed space. The closed space is to isolate light and prevent light interference, but does not block air circulation with the outside world outside the closed space.

[0102] The closed space is specifically: the first surface is formed by the bottom of the light source part, the second surface is formed by the upper surface of the upper support seat, and the side wall is formed by the annular boss, which together form an enclosed space; wherein the height of the annular boss constitutes the distance between the first surface and the second surface.

[0103] In a preferred embodiment, the second boss and the annular boss are of the same height, specifically 2-3 mm, so the distance between the light source on the housing and the light-transmitting hole is also 2-3 mm.

[0104] In the present invention, the light source is arranged in the housing, and a small LED lamp and a small battery (button battery) are arranged in the housing, and the lamp and the battery are connected by a conductor. The space inside the housing is large, and the lamp and the battery are installed in any way, and it is only necessary to ensure that the lamp is directly irradiated into the light transmission hole. With the light source, the interference of the boundary light is eliminated, so that the present invention can observe the sample more clearly through the microscope.

[0105] The dripping hole is arranged near the annular boss; the height of the annular boss near the dripping hole is lower than the rest of the part, forming a gap on the annular boss; due to the small volume of this product, when the liquid specimen is dripped into the dripping hole, if the annular boss is too close to the dripping port, it will affect the dripping operation of the liquid specimen into the dripping hole, so a gap should be provided on the annular boss near the dripping port (for ease of understanding and to distinguish it from other terms, it is named here: annular boss gap). The center of the annular boss gap is in the same straight line as the axis of the dripping hole, the light-transmitting hole, and the air hole, and the air hole is located away from the annular boss. This can prevent body fluids from accidentally dripping into the air hole during operation.

[0106] Example 5:

[0107] The fixed illumination light source is located above the light transmission hole and is coaxial with the light transmission hole and the observation hole, so that the light can directly penetrate onto the glass stage, pass through the glass stage and the body fluid sample, and then pass out from the observation hole.

[0108] The light-transmitting hole and the observation hole are located at one of the left and right ends excluding the center of the support seat. The light-transmitting hole and the lens of the microscope have the same central axis, and the central axis is not in the central part of the body fluid detection device, but close to the left 3 / 4 to 1 / 3 of the device. Specifically, taking the observation hole as an example, the observation hole is set on the lower support seat, and the overall shape of the lower support seat is a rectangular plate. The first virtual symmetry center line parallel to the long side of the rectangle divides the rectangular plate into two parts, front and back, and the second virtual symmetry center line parallel to the short side of the rectangle divides the rectangular plate into two parts, left and right. The center of the observation hole is on the first virtual symmetry center line, and the center of the observation hole is 3 / 4 to 1 / 3 on the left side of the lower support seat.

[0109] That is, the observation hole, light-transmitting hole, and microscope lens in the device are all set to the left (or right). The purpose is: since the device is placed on the mobile phone camera for use, it is actually best to use it on the mobile phone front camera, and the mobile phone front camera is usually set at the top edge of the mobile phone. If the microscope lens of the device is set in the center of the device, then after the device is placed on the mobile phone and aligned with the camera, nearly half of the weight of the device is outside the edge of the mobile phone, which makes it easy to fall from the edge; if the microscope lens of the device is set on the left part, then after the device is placed on the mobile phone and aligned with the mobile phone camera, the center of gravity of the device remains within the edge of the mobile phone to prevent it from falling.

[0110] Example 6:

[0111] The outer shell, support base, and all inner walls of the enclosed space are made of black light-absorbing material; the best way is that the outer shell and support base are made of black plastic, and the surface is frosted to achieve the effect of attracting light.

[0112] An asymmetric concave-convex structure is provided on the annular boss, and the asymmetric concave-convex structure is as follows: a convex-concave opening that excludes the center of the upper seat is provided on the annular boss to be symmetrical, and a convex-concave structure corresponding to the convex-concave opening is provided on the second boss. A circle of annular bosses is provided around the upper seat, and the purpose of the annular bosses is to facilitate the buckling of the outer shell with the annular bosses, and the two are installed together, so that the outer edge of the lower opening of the outer shell is buckled on the annular bosses. In order to prevent the outer shell and the upper seat from being buckled by mistake (causing reverse buckling or buckling in the wrong direction due to unskilled use by consumers), an asymmetric concave-convex structure is provided at the corresponding position of the annular boss and the lower opening of the outer shell. When buckled in the wrong direction, it cannot be buckled due to the mismatch of the concave-convex structure; what is described here is a fool-proof design.

[0113] In one embodiment, since the second boss of the housing surrounds the annular boss, the second boss is provided with an anti-foolproof notch 16, and a convex structure 28 corresponding to the anti-foolproof notch is provided on the outer side of the annular boss. When the light source is aligned with the light-transmitting hole, the second boss just fits the annular boss to complete the installation. However, when the user fails to align the light source with the light-transmitting hole, for example, the light source is taken to the right and the light-transmitting hole is taken to the left, the convex structure 28 on the annular boss will support the second boss, making it impossible for the second boss to fit with the annular boss for installation. Of course, in order to guide the user, the anti-foolproof notch 16 and the convex structure 28 may be designed to be eye-catching and as large as possible.

[0114] One example is that the foolproof notch and the convex structure are only set on the right and are set on the right at the same time. One example is that the foolproof notch and the convex structure are only set on the left and are set on the left at the same time. One example is that the foolproof notch and the convex structure are only set on the left and are set on the right at the same time, but the two have a large size difference that is easily recognizable.

[0115] Example 7:

[0116] When the user drips the body fluid from the drip hole, the body fluid falls into the drip hole, and under the action of atmospheric pressure, flows along the air permeable gap, through the lens of the microscope in the small hole, it is observed exactly at the lens of the microscope in the small hole, and at the same time, the light-transmitting hole is also exactly at the lens of the microscope in the small hole, so the small hole, the light-transmitting hole, and the lens of the microscope all have the same central axis. The factory state of the present invention is that the light source part is an independent part, referred to as the first part here; the body fluid sample placement and optical lens assembly part is another independent part, referred to as the second part here.

[0117] When in use, first lay the second part flat, keeping the upper support seat at the top and the lower support seat at the bottom. Expose the three holes (light-transmitting hole, dripping hole and air-permeable hole) arranged in a straight line with the center of the circle, drip the body fluid specimen into the dripping hole, and the specimen flows under the cover glass. Snap the light source part onto the top of the upper support seat, and the fool-proof design allows the user to more easily align the light-transmitting hole with the light-transmitting hole. After snapping, the second part and the first part are spliced ​​into a whole, which is the body fluid detection device of the present invention. Move the present invention above the camera of a mobile phone, preferably the front camera. Turn on the front camera of the mobile phone and display the picture on the screen of the mobile phone. Press the button switch to turn on the light source. When adjusting the position of the device, the center of the microscope is facing the center of the mobile phone camera. At this time, the body fluid magnified by the microscope can be seen on the mobile phone screen. For example, if the body fluid is semen, the movement of sperm can be seen.
