Detailed Description
In order to make the technical problems, technical solutions and advantageous effects of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 2, the present capsule endoscope contamination detection apparatus is designed to detect whether the imaging lens 12 and the transparent cover 13 surface of the capsule endoscope in fig. 2 are contaminated, to ensure that: 1. the capsule endoscope is clean before shipment. If dirt is on the transparent cover 13, the health of the swallow staff can be affected. 2. The transparent cover 13 is dirty, which can block the shot part in the alimentary canal and influence the imaging of the capsule endoscope. 3. If there is dirt on the imaging lens 12, it will block light entering the imaging lens 12 and also affect the imaging of the capsule endoscope.
Referring to fig. 3, the present apparatus is provided with a slide plate 301 and a fixing plate 302, and when it is necessary to detect contamination of the capsule endoscope, the capsule endoscope 1 is placed in the apparatus 3. At this time, the slide plate 301 is closest to the capsule endoscope 1, and the fixed plate 302 is farther from the capsule endoscope 1, that is, the slide plate 301 is disposed between the capsule endoscope 1 and the fixed plate 302. The end surface of the slide plate 301 facing the capsule endoscope 1 is provided with a second light emitting element 3011, and a yellow silicone sheet 3012 is laid on the second light emitting element 3011 (see fig. 5 and 7). That is, the second light emitting element 3011 is placed in a groove of the slide board 301, and then the yellow silicone sheet 3012 is laid on the slide board 301. The silica gel skin is selected to be yellow so as to meet the requirement of being similar to the color of the inner walls of human intestines and stomachs, and the color of the inner walls of the human intestines and stomachs is flesh color and is very close to yellow. The end face of the fastening plate 302 facing the capsule endoscope 1 is coated with a non-reflective black coating 3022 (see fig. 6). At the time of testing, the capsule endoscope 1 needs to be placed in a dark empty box in order to avoid the influence of stray light on the detection result. When the capsule endoscope 1, the sliding plate 301 and the fixing plate 302 are arranged and are all in a dark empty box, the switch 320 is started to enable the second light-emitting element 3011 to emit light to illuminate the yellow silica gel sheet 3012, because the sliding plate 301 is blocked in front of the fixing plate 302, light emitted by the first light-emitting element 11 arranged in the capsule endoscope 1 penetrates through the transparent cover 13 and then irradiates on the yellow silica gel sheet 3012, after being reflected by the yellow silica gel sheet 3012, reflected light is transmitted by the imaging lens 12 and then reaches the imaging unit (not shown) in the capsule endoscope 1, the imaging unit images the yellow silica gel sheet 3012, the processor 314 in the device 3 processes an image obtained by shooting of the imaging unit and then transmits the image to a computer (not shown) connected with the device, the computer displays the first image obtained by shooting of the imaging unit, and a detection person can judge whether the imaging lens 12 has dirt or not according to the first image. If there is no smudging on the imaging lens 12 (i.e., the imaging lens has a very clean mirror surface), the resulting first image is shown in fig. 8. Referring to fig. 8, the circular area in fig. 8 is yellow (the picture color is here treated as black and white to meet the patent application requirements), which is consistent with the color of the yellow silicone skin 3012. In fig. 8, no black dot appears in the circular area, indicating that there is no contamination on the imaging lens 12; if a black dot appears in the circular area in fig. 8, it indicates that there is a stain on the imaging lens 12. The more black dots, the more serious the degree of the mirror surface contamination of the imaging lens 12; the fewer black dots, the more slight the degree of the mirror surface contamination of the imaging lens 12.
When the contamination detection of the imaging lens 12 is completed, the switch 320 is closed, the second light emitting element 3011 stops emitting light, and the slide plate 301 is slid to withdraw the slide plate 301 out of the optical path of the first light emitting element 11 of the capsule endoscope 1. Meanwhile, the first light emitting element 11 is kept in a light emitting state from the detection, the emitted light is incident on the black coating layer 3021 on the fixed plate 302 through the transparent cover 13, an imaging unit (not shown) in the capsule endoscope 1 captures an image of the transparent cover 13, and the processor 314 in the apparatus processes a second image captured by the imaging unit and then transmits the second image to a computer (not shown). After the second image capturing is completed, the control button 321 is pressed to turn off the capsule endoscope 1, and at this time, the first light emitting element 11 built in the capsule endoscope 1 does not emit light any more, and the capsule endoscope 1 stops operating. The computer displays the second image obtained by the imaging unit, and the detection personnel can judge whether the transparent cover 13 has dirt or not according to the second image. If there is no smudging on the transparent cover 13 (i.e. the surface of the transparent cover 13 is clean), a second image is obtained as shown in fig. 9. Specifically, if there are no white dots in the circular area in fig. 9, it indicates that the transparent cover 13 is not soiled. If dirt adheres to the transparent cover 13, the second image obtained is as shown in fig. 10, and many white dots appear in the circular area; the more white dots, the more severe the fouling of the transparent cover 13; the less white spots, the less fouling was indicated.
Referring to fig. 3, as one embodiment, the dark space box mentioned above is enclosed by a first upper plate 305, a first rear plate 303, a first left plate 304, a first front plate 306, a fixed plate 302 and a second upper plate 310. The first upper plate 305, the first back plate 303, the first left plate 304 and the fixing plate 302 are enclosed on the second upper plate 310 to form four sides of a hexagon, and the first upper plate 305 and the second upper plate 310 form upper and lower planes of the hexagon. The reason why the capsule endoscope 1 needs to be placed in a dark empty box is to prevent the detection result from being affected by stray light other than the first light-emitting element 11 and the second light-emitting element 3011 when the capsule endoscope 1 is subjected to a stain test.
With continued reference to fig. 3, a first hinge (not shown) is disposed at the joint of the first upper plate 305 and the first left plate 304, and the first upper plate 305 and the first left plate 304 are connected together by the first hinge. On the first upper plate 305, a carrying handle 3051 is provided, and the first upper plate 305 can be opened and closed by holding the carrying handle 3051.
Referring to fig. 3, a fixing base 307 is disposed in the dark space (i.e., the hexagonal space), a groove 3071 is disposed on the fixing base 307, and the capsule endoscope 1 is placed in the groove 3071, so as to position the capsule endoscope 1.
Referring to fig. 3, 4 and 7, the slide plate 301 slides on the second upper plate 310 as follows: a chute 3101 (see fig. 7) is provided on the second upper plate 310, and the arrangement direction of the chute 3101 is perpendicular to the axial line direction of the capsule endoscope 1. The lower end of the slide plate 301 is inserted into the slide groove 3101, and the slide plate 301 is movable in the slide groove 3101 in a direction perpendicular to the axial direction of the capsule endoscope 1. Referring to fig. 4 and 7, a right end face of the slide plate 301, i.e., a face opposite to the yellow silicone sheet 3012, is detachably connected to one end of the pulling plate 308. The other end of the pulling plate 308 passes through the through hole 3061 of the first front plate 306 and is exposed to the dark space. When the operator holds the pull block 309, the slide plate 301 can be slid in the slide groove 3101 by pulling the pull block 309. It should be noted that the arrangement direction of the chute 3101 in the dark space is perpendicular to the arrangement direction of the capsule endoscope 1 along the axis in the fixing base 307, and the purpose of the chute is to make the light emitted from the first light emitting element 11 of the capsule endoscope 1 directly irradiate the yellow silica gel sheet 3012 and the black coating 3021.
Referring to fig. 3, the processor 314 is disposed in a space formed by the second upper plate 310, the second rear plate 311, the second left plate 312, the second front plate 313, the right plate 315, and the lower plate 318, which is larger than the aforementioned black space. A second hinge 319 is provided at the junction of the second upper plate 310 and the right plate 315. On right plate 315, be provided with and carry hand ring 316, on second left plate 312, be provided with and carry hand ring 317. The entire detection device 3 can be conveniently moved to other places by gripping the two lifting/pulling rings 316 and 317 with both hands.
Referring to fig. 3, a switch 320 is further disposed on the second upper plate 310, and the switch 320 is electrically connected to the processor 314 for controlling the light emission of the second light emitting element 3011 (fig. 7). A control button 321 for turning off the capsule endoscope after completion of contamination detection of the imaging lens and the transparent cover of the capsule endoscope.
The dirty test process of the capsule endoscope comprises the following steps: the first step is as follows: the first upper plate 305 is opened, the capsule endoscope 1 is placed in the groove 3071 on the fixed seat 307, and the end of the transparent cover 13 is close to the sliding plate 301, so that the distance from the rightmost end (see fig. 2) of the transparent cover 13 to the yellow silica gel sheet 3012 is not more than 2mm, and the distance from the rightmost end to the left end face of the fixed plate 302 is not less than 50mm; meanwhile, the first light-emitting element 11 of the capsule endoscope keeps emitting light all the time in the whole process of the dirt test of the imaging lens and the dirt test of the transparent cover; the second step: covering the first upper plate 305 to keep the capsule endoscope 1 in a dark environment; meanwhile, the whole testing device is normally connected with a computer; thirdly, detecting the dirt of the imaging lens: turning on the switch 320 to make the second light emitting element 3011 emit light to illuminate the yellow silica gel sheet 3012, and displaying a dirty test result picture of the imaging lens 12 (see fig. 2) taken by the capsule endoscope by the computer (similar to fig. 8); then, the switch 320 is turned off, and the second light-emitting element 3011 is turned off; fourth, the slide plate 301 is slid in the slide groove 3101 by pulling the pull block 309, and the light path of the capsule endoscope 1 is removed, and at this time, the light emitted from the first light emitting element 11 is irradiated onto the black coating layer 3021 of the fixed plate 302, and the computer displays a stain test photograph of the transparent cover 13 captured by the capsule endoscope (similar to fig. 9 and 10). Finally, the control button 321 is pressed, the capsule endoscope 1 is closed, the first upper plate 305 is opened, and the capsule endoscope 1 is taken out, thereby completing the contamination test process of one capsule endoscope 1. Then, the next capsule endoscope is put in, and the first upper plate 305 is closed, and the first to fourth steps above are repeated to perform the contamination test on the next capsule endoscope.
It is explained that the smear test is performed on the imaging lens 12 (see fig. 2) so that the distance from the rightmost end of the transparent cover 13 to the yellow silicone sheet 3012 is 2mm or less (see fig. 4) when the capsule endoscope is tested, and so that the distance from the rightmost end of the transparent cover 13 to the left end of the fixing plate 302 is 50mm or more (see fig. 4) when the smear test is performed on the transparent cover 13. This is because in order to satisfy the requirement that the capsule endoscope can photograph the gastrointestinal inner wall in the narrow space of the intestines and stomach in the largest range, the field angle of the imaging lens 12 is as large as possible; meanwhile, when the imaging lens is subjected to a contamination test, the requirement that the light intensity of the first light-emitting element 11 is high enough is met, so that the distance from the rightmost end of the transparent cover 13 to the yellow silica gel sheet 3012 is set to be less than or equal to 2mm; when the transparent cover 13 is subjected to a dirt test, the requirement on the light intensity is relatively low, so that the setting of more than or equal to 50mm is reasonable.
To sum up, this detection device can carry out dirty the detection with lower cost to the imaging lens and the translucent cover of capsule endoscope in batches, and the testing result is accurate, and detection efficiency is high.
The first light-emitting element 11 and the second light-emitting element 3011 are preferably LED lamps because the LED lamps have advantages of uniform light emission and high light emission intensity.
It should be noted that the device can be used for detecting the contamination of the stomach capsule and the contamination of the intestine capsule. The dirty detection of the stomach capsule is to perform dirty detection on the imaging lens and the transparent cover, and the dirty detection of the intestine capsule is also to perform dirty detection on the imaging lens and the transparent cover. Thus, the capsule of fig. 1 and 2 may be either a gastric or intestinal capsule.
The present invention is not limited to the above-described preferred embodiments, but rather, the present invention is intended to cover all modifications, equivalents, and improvements falling within the spirit and scope of the present invention.
