Referring to FIGS. 1 ̃10, a package for a capsule endoscope is provided, comprising an inner package 2. The inner package 2 comprises a base 21 and a cover 22 arranged above the base 21. A first end of the cover 22 is connected to a first side of the base 21 and a second end of the cover 22 is connected to a second side of the base 21 in an assembled mode. When the second end of the cover 22 is assembled and connected to the second side of the base 21, the bottom surface of the cover 22 and the base 21 form an holding slot 25 for holding the capsule endoscope 8.
Referring to FIGS. 1 ̃3, the package is provided with a separate inner package 2, and the inner package 2 comprises a base 21 and a cover 22. The cover 22 is connected to the base 21 in an openable mode, i.e., the first end of the cover 22 is connected to the first side of the base 21, and the second end of the cover 22 is connected to the second side of the base 21 in an assembled mode. When the cover 22 and the base 21 are assembled and closed, the bottom surface of the cover 22 and the base 21 form a holding slot 25 for holding the capsule endoscope 8.
The base 21 can be a plastic base 21, and the holding slot 25 can be directly formed by the upper surface of the base 21 and the cover 22, or the base 21 can comprise a holder 212, and the holder 212 forms the holding slot 25 with the cover 22. The method of connecting the cover 22 to the base 21 is not limited. The first end of the cover 22 may be rotatably connected to the first side of the base 21 by means of pivot connection. The second end of the cover 22 may be connected to the second side of the base 21 by means of snap connection. The extending direction of the holding slot 25 may be cross-perpendicular to the cover 22 or parallel to the length direction of the cover 22.
Therefore, the cover 22 and the base 21 can be connected in an openable mode. When the cover 22 and the base 21 are closed, the cover 22 can form a holding slot 25 with the base 21 to hold the capsule endoscope 8, thus ensuring the reliability of the capsule endoscope 8 during transportation and avoiding the previous squeezing contact that results in overall press and stress on the capsule endoscope 8.
Further, the first end of the cover 22 is pivotally connected to the first side of the base 21.
Further, the second end of the cover 22 is provided with a first snap hook 223, and the second side of the base 21 is provided with a fitted limit portion 213. The first snap hook 223 can fit with the limit portion 213 to connect the cover 22 to the base 21 by means of snap fit.
In the embodiments of the present invention, the cover 22 is configured as a rotating structure with snap hook. Specifically, the first end of the cover 22 is rotatably connected to the first side of the base 21 by means of pivot connection, and the second end of the cover 22 can be assembled and connected with the second side of the base 21 or disconnected from each other. In addition, the second end of the cover 22 can be assembled and connected to the second side of the base 21 in the form of snap connection, wherein the second end of the cover 22 is provided with a first snap hook 223 and the second side of the base 21 is provided with a fitted limit portion 213. By pressing the second end of the cover 22, the first snap hook 223 and the limit portion 213 snap together, thus fixing the cover 22 and the base 21 in a closed state, and forming a holding slot 25 between the cover 22 and the base 21. Also, the first snap hook 223 can be opened so that the first snap hook 223 and the limiting portion 213 are separated from each other for taking out of the capsule endoscope 8.
Further, the bottom surface of the cover 22 is provided with a soft rubber structure 221. When the second end of cover 22 is assembled and connected to the second side of the base 21, the soft rubber structure 221 and the base 21 form the holding slot 25.
Further, the soft rubber structure 221 is an arc-shaped soft rubber structure 221 whose surface shape is adapted to the shape of the outer surface of the capsule endoscope 8, and the arc-shaped soft rubber structure 221 can form a cylindrical holding slot 25 with the base 21.
Further, the inner diameter of the cylindrical holding slot 25 matches the outer diameter of the capsule endoscope 8.
To reduce the impact of damage to the capsule endoscope 8 during transportation or other processes, a soft rubber structure 221 is embedded on the bottom surface of the cover 22, and the soft rubber structure 221 and the base 21 form a holding slot 25. When the capsule endoscope 8 is placed in the holding slot 25, the soft rubber structure 221 can directly contact or interfere with the capsule endoscope 8.
Preferably, the surface of the soft rubber structure 221 can be set in an arc-shaped shape to fit the shape of the outer surface of the capsule endoscope 8. At this time, the arc-shaped soft rubber structure 221 and the base 21 can form a cylindrical holding slot 25. When the arc-shaped soft rubber structure 221 is in contact with the base 21, the contact area of the outer surface of the capsule endoscope 8 receives uniform force, which can effectively alleviate the influence of forces such as friction or squeezing. The top surface of the base 21 can also be recessed to form an arc-shaped surface, so that the cylindrical holding slot 25 is located in the recessed part of the base 21.
Also, the inner diameter of the cylindrical holding slot 25 is set to be the same as or slightly less than the outer diameter of the capsule endoscope 8. In the embodiment, the range of the difference between the inner diameter of the cylindrical holding slot 25 and the outer diameter of the capsule endoscope 8 is 0-0.5 mm. Preferably, the inner diameter of the cylindrical holding slot 25 is 0.2 mm less than the outer diameter of the capsule endoscope 8.
When the inner diameter of the cylindrical holding slot 25 and the outer diameter of the capsule endoscope 8 are the same in size, the arc-shaped soft rubber structure 221 directly contacts the capsule endoscope 8 to limit and fix the capsule endoscope 8.
When the inner diameter of the cylindrical holding slot 25 is slightly less than the outer diameter of the capsule endoscope 8, the arc-shaped soft rubber structure 221 and the capsule endoscope 8 interfere with each other, and a large distributed friction force can be produced to fix the capsule endoscope 8. The arc-shaped soft rubber structure 221 can be arranged in the middle of the cover 22, and the cover 22 is perpendicular to the cylindrical holding slot 25, that is, the arc-shaped soft rubber structure 221 wraps the outer surface of the capsule endoscope 8, and the two interfere with each other. In this case, the radial direction of the capsule endoscope 8 is completely restricted, and it only has degree of freedom in the axial direction, while the cover 22 provides a large enough friction force to make the capsule endoscope 8 be firmly fixed, so as to meet the requirements of reliable fixation.
Further, the base 21 comprises a base body 211 and a holder 212 fixedly connected to the base body 211. When the second end of the cover 22 is assembled and connected to the second side of the base 21, the soft rubber structure 221 and the holder 212 form the holding slot 25.
Specifically, the base 21 comprises a base body 211 and a holder 212, and the holder 212 is fixedly disposed on the base body 211, wherein, the holder 212 may be provided with an arc-shaped recessed portion. When the second end of the cover 22 and the second side of the base 21 are fixed to each other, the arc-shaped recessed portion of the holder 212 forms a holding slot 25 with the soft rubber structure 221 on the cover 22.
The base 21 can be a plastic base, and the holder 212 can be a soft rubber holder. The soft rubber holder 212 is fixedly connected to the plastic base 21 by means of adhesive. After the cover 22 is closed, the soft rubber holder 212 and the soft rubber structure 221 form the holding slot 25. The surface shape of the soft rubber structure 221 is not limited. Preferably, the surface shape of the soft rubber structure 221 can be made to an arc shape, that is, the arc-shaped soft rubber structure 221 and the holder 212 can form a cylindrical holding slot 25.
After the capsule endoscope 8 is placed in the holding slot 25, the soft rubber holder 212 pre-clamps the capsule endoscope 8. Then, under the gravity or squeezing force of the capsule endoscope 8, the force of interference or friction from the soft rubber is moderate and can effectively support and protect the capsule endoscope 8.
Further, the length of the holding slot 25 is not greater than the length of the middle enclosure 82 of the capsule endoscope 8.
Two ends of the capsule endoscope 8 are distributed with camera enclosures, which are untouchable. Only the middle enclosure 82 has no optical requirements and can be used to fix and pick up the capsule endoscope 8.
In order to protect the shooting effect of the camera, the length of the holding slot 25 is restricted, so that only the middle enclosure 82 is in contact with the holding slot 25 after the capsule endoscope 8 is placed in the holding slot 25, and the camera enclosures at two ends protrude out of the holding slot 25 to avoid contact between the camera enclosures and the holding slot 25.
Preferably, the holding slot 25 comprises reserved space for fingers to pinch the capsule endoscope 8, and the reserved space for fingers corresponds to the position of the middle enclosure 82 of the capsule endoscope 8 so as to pinch the middle enclosure 82 of the capsule endoscope 8 for convenient placement when packaging and take out for use.
Further, referring to FIG. 4, the package further comprises a sealing structure 4. The sealing structure 4 comprises a blister case 41 and a dialysis paper 42. The surface of the blister case 41 is recessed to form a first holding chamber 45. The inner package 2 can be fixed in the first holding chamber 45. The dialysis paper 42 can be seamlessly connected to the upper surface edge of the blister case 41 to seal the first holding chamber 45.
After the capsule endoscope 8 is placed in the inner package 2 and fixed therein, a fixed integral structure is formed, the fixed integral structure can be put into the sealing structure 4 for sealing.
Specifically, the package further comprises a sealing structure 4, which comprises a blister case 41 and a dialysis paper 42. The surface of the blister case 41 is recessed to form a first holding chamber 45, and the blister case 41 may also be provided with a concave-convex structure 413. After putting the entire inner package 2 into the first holding chamber 45, the concave-convex structure 413 can limit and fix the entire inner package 2 so that the entire inner package 2 is relatively fixed with the blister case 41. Then, the upper surface edge of the blister case 41 can be connected to the dialysis paper 42 by heat sealing to seal the first holding chamber 45. The dialysis paper 42 has the function of breathing and bacteria isolating, and provides aseptic guarantee for storage of the capsule endoscope 8, that is, the sealed integral structure can be subsequently sterilized as a whole.
The method of fixing the inner package 2 as a whole to the blister case 41 is not limited. Other method such as fixing by adhesive may also be used.
Further, the package further comprises an outer package 6. The outer package 6 comprises an upper cover 61 and a lower cover 62 that are detachably connected, and the upper cover 61 and the lower cover 62 form a second holding chamber 65. The sealing structure 4 can be fixed in the second holding chamber 65.
After the capsule endoscope 8 is fixed to the inner package 2, the closed inner package 2 is placed in the sealing structure 4 for overall sterilization or aseptic sealing, and then the sealed and sterilized overall structure is continued to go through outer packaging.
Referring to FIG. 5, the package further comprises an outer package 6 and the outer package 6 comprises an upper cover 61 and a lower cover 62. The second holding chamber 65 is formed between the upper surface of the lower cover 62 and the lower surface of the upper cover 61, which can be formed by recessing the upper surface of the lower cover 62, by recessing the lower surface of the upper cover 61, or by recessing the both.
After the sealing structure 4 is wholly placed into the second holding chamber 65, the upper cover 61 is detachably connected to the lower cover 62, which may be either by connecting the upper cover 61 to at least two sides of the lower cover 62 with a sealing sticker 63, or by connecting the upper cover 61 to the lower cover 62 rotatably and openably by means of a snap hook and a pivot, to facilitate opening or closing.
Preferably, the upper surface of the lower cover 62 is recessed to form a second holding chamber 65 with the upper cover 61, wherein the lower surface of the upper cover 61 may also be recessed. The lower cover 62 may also be provided with a second snap hook 623, which fits the concave and convex structure 413 on the blister case 41, and the two may cooperate to fix the lower cover 62 relative to the blister case 41, thereby fixing the sealed and sterilized overall structure with the lower cover 62. Alternatively, a double-sided tape may be used to adhere the bottom of the blister case 41 to the lower cover 62.
The following is an overall description in conjunction with specific embodiments.
As shown in FIGS. 6 to 10, the package comprises a separate inner package 2, a sealing structure 4, and an outer package 6.
The inner package 2 comprises a base 21 and a cover 22, and the base 21 is constructed of plastic. The base 21 comprises a base body 211 and a holder 212. The holder 212 can be a soft rubber holder. The upper surface of the base body 211 is recessed, the holder 212 is located in the recessed area and is fixed to the base body 211. The holder 212 is designed with corresponding arc-shaped recesses on two sides for placing the capsule endoscope 8, and the other two sides of the holder 212 are provided with reserved space for fingers to take out the capsule endoscope 8. One end of the cover 22 pivotally connected to the base 21, and the other end of the cover 22 is provided with a first snap hook 223 that is connected to the limit portion 213 on the base 21 by means of snap fit. The lower surface of the cover 22 is provided with a soft rubber structure 221, which is parallel to the direction of the reserved space for fingers, and the surface of the soft rubber structure 221 is arc shaped to match the outer surface of the capsule endoscope 8, that is, the surface of the soft rubber structure 221 is the same as the outer surface of the capsule endoscope 8. Thus, the arc-shaped soft rubber structure 221 and the arc-shaped recessed portion of the holder 212 form a cylindrical holding slot 25. Also, the length of the holding slot 25 is smaller than the length of the middle enclosure 82 of the capsule endoscope 8, so that only the middle enclosure 82 of the capsule endoscope 8 is in contact with the holding slot 25 which has no contact with two ends of the capsule endoscope 8 with optical lens.
After the capsule endoscope 8 is put in the inner package 2, the cover 22 is pressed to be fixed to the base 21, so that the arc-shaped soft rubber structure 221 can be in direct contact with the capsule endoscope 8 or interfere with the capsule endoscope 8 so as to fix the capsule endoscope 8 firmly.
The sealing structure 4 comprises a blister case 41 and a dialysis paper 42. The surface of the blister case 41 is recessed to form a first holding chamber 45, and the blister case 41 is provided with a concave-convex structure 413. After the capsule endoscope 8 is fixed in the inner package 2, a fixed whole structure is formed, the fixed whole structure is put into the blister case 41, and the concave-convex structure 413 can press against the upper surface of the fixed whole structure to fix the whole structure relative to the blister case 41. The dialysis paper 42 can be thermally connected to the edges of the upper surface of the blister case 41 to seal the first holding chamber 45 for subsequent overall sterilization.
The outer package 6 comprises an upper cover 61 and a lower cover 62. The upper surface of the lower cover 62 is recessed to form a second holding chamber 65 with the upper cover 61. The lower cover 62 is provided with a second snap hook 623. After the sealed and sterilized whole structure is put into the second holding chamber 65, the second snap hook 623 fits with the concave-convex structure 413 on the blister case 41 to fix the lower cover 62 relative to the sealed and sterilized whole structure. At least two sides of the upper cover 61 and the lower cover 62 are detachably connected to each other by a sealing sticker 63, to finally complete the overall package of the capsule endoscope 8.
Referring to FIGS. 11-13, the fitting structure between the inner package 2, the sealing structure 4, and the outer package 6 is described in detail below with a specific example.
The inner package 2 is used to hold the capsule endoscope 8. The sealing structure 4 comprises a blister case 41 and a dialysis paper 42. The surface of the blister case 41 is recessed to form a first holding chamber 45 for accommodating the inner package 2, and the dialysis paper 42 is seamlessly connected to the upper surface edge of the blister case 41 to seal the first holding chamber 45. The outer package 6 is used to hold the sealing structure 4. The inner package 2 comprises a first fitting structure 214, the sealing structure 4 comprises a second fitting structure 413, and the outer package 6 comprises a third fitting structure 623. The second fitting structure 413 is mutually limited with the first fitting structure 214 and the third fitting structure 623 respectively.
Here, the blister case 41 and the dialysis paper 42 fit with each other to form a sealed first holding chamber 45. The dialysis paper 42 is air permeable and can isolate bacteria to provide a sterile guarantee for the storage of the capsule endoscope 8. In addition, the sealing structure 4 is mutually limited with both the inner package 2 and the outer package 6 to improve reliability during transportation and avoid damage to the capsule endoscope.
The inner package 2 comprises a base 21 for holding the capsule endoscope 8. The outer package 6 comprises a lower cover 62, and the lower cover 62 comprises a second holding chamber 65 for holding the sealing structure 4. The first fitting structure 214 comprises a peripheral area of the base 21. The second fitting structure 413 comprises a concave-convex structure 413 located on the blister case 41. The third fitting structure 623 comprises a second snap hook 23 located on the lower cover 62. The concave-convex structure 413 limits the base 21 and the second snap hook 623 limits the concave-convex structure 413.
It can be seen that the inner package 2 and the sealing structure 4 are fixed to each other through the concave-convex structure 413 and the base 21, and the sealing structure 4 and the outer package 6 are fixed to each other through the concave-convex structure 413 and the second hook 623. That is, the arrangement of the concave-convex structure 413 realizes the fixation between the sealing structure 4 and both the inner package 2 and the outer package 6.
Further, the concave-convex structure 413 is located on the side wall 414 of the blister case 41 and protrudes toward the first holding chamber 45. The side of the concave-convex structure 413 facing the first holding chamber 45 is a bracing portion 4131 and the side of the concave-convex structure 413 away from the first holding chamber 45 is a recess 4132. The bracing portion 4131 abuts against the peripheral area of the base 21, and the recess 4132 fits with the second snap hook 623.
Here, the “peripheral area of the base 21” refers to the outermost area as shown in FIG. 11. When viewed from the first holding chamber 45, the concave-convex structure 413 is in the shape of a bump, and the outer surface of the concave-convex structure 413 constitutes the bracing portion 4131. The lower end surface of the bracing portion 4131 abuts against the upper end surface of the peripheral area 214 of the base 21. In this way, the blister case 41 restricts the movement of the base 21 in the vertical direction, and the vertical direction is the superimposed direction of the blister case 41 and the base 21. In addition, the inner surface of the concave-convex structure 413 away from the first holding chamber 45 forms a recess 4132, and the second snap hook 623 is inserted into the recess 4132 to achieve the engagement between the outer package 6 and the sealing structure 4.
Preferably, the concave-convex structure 413 is integrally formed with the blister case 41. In practice, the concave-convex structure 413 can be directly formed by a blister process during the molding of the blister case 41. The concave-convex structure 413 is actually formed by recessing (or projecting) part of the blister case 41.
Specifically, the inner package 2 further comprises a cover 22 arranged above the base 21. The first end of the cover 22 is connected to the first side of the base 21 and the second end of the cover 22 is connected to the second side of the base 21 by means of snap fit. The peripheral area 214 of the base 21 comprises a first periphery 214a set accordingly to the second side of the base 21, and a second periphery 214b and a third periphery 241c connected to the two ends of the first periphery 214a. The concave-convex structure 413 comprises a first concave-convex structure 413a, a second concave-convex structure 413b and a third concave-convex structure 413c arranged correspondingly to the first periphery 214a, the second periphery 214b and the periphery 214c. 
Here, “a first periphery 214a set correspondingly to the second side” refers to that the first periphery 214a is set adjacent to the second side. In the embodiment, the first periphery 214a is located at the end of the second side away from the first side. The heights of the periphery 214a, the second periphery 214b and the third periphery 241c are equal. The peripheral area 214 is limited in three directions by the concave-convex structure 413, which can achieve a stable fit between the inner package 2 and the sealing structure 4. In addition, the lower cover 62 comprises three second hooks 623 corresponding to the first concave-convex structure 413a, the second concave-convex structure 413b and the third concave-convex structure 413c. 
Further, the lower cover 62 comprises a bottom portion 621 and an outer peripheral portion 622 disposed around the bottom portion 621. The outer peripheral portion 622 comprises an opening S cut in a side away from the bottom portion 621. The second hook 623 is connected to the bottom portion 621 and extends toward the opening S. At this point, the second hook 623 is disposed roughly parallel to the outer peripheral portion 622.
Specifically, the lower cover 62 further comprises an inner peripheral portion 624 connected to the bottom portion 621 and spaced apart from the outer peripheral portion 622. The inner peripheral portion 624 comprises an inner peripheral body 6241 and a second snap hook 623. The inner peripheral portion 624 encloses a second holding chamber 65. When the sealing structure 4 is accommodated in the second holding chamber 65, the inner peripheral body 6241 abuts the outer surface 415 of the blister case 41, and the second snap hook 623 fits with the concave-convex structure 413.
Here, the inner peripheral portion 624 and the outer peripheral portion 622 are roughly parallel to each other. The inner peripheral portion 624 is located inside the outer peripheral portion 622, and the inner peripheral portion 624 fits with the blister case 41, specifically the inner peripheral body 6241 fits with the outer side surface 415 of the blister case 41. Also, the second hook 623 fits with the concave-convex structure 413 at the side wall 414 of the blister case 41. The inner peripheral body 6241 and the second snap hook 623 simultaneously limit the blister case 41, so as to greatly improve the limit effect.
A gap P exists between the second snap hook 623 and the inner peripheral body 6241, and the existence of the gap P can help the second snap hook 623 to be slightly deformed to be snapped into the concave-convex structure 413.
In this case, the bottom end of the second snap hook 623 is interconnected with the bottom end of the inner peripheral body 6241, and a gap P exists between the two sides of the upper end of the second snap hook 623 and their adjacent inner peripheral body 6241, so that the deformation of the second snap hook 623 can be guaranteed while ensuring the overall strength of the inner peripheral portion 624.
Further, the second snap hook 623 protrudes from the inner peripheral body 6241 toward the opening S, and the upper end surface of the outer peripheral portion 622 is farther away from the bottom portion 621 than the upper end surface of the inner peripheral body 6241.
That is, in the vertical direction, the height of the inner peripheral body 6241 is smaller than the height of the second hook 623, while the height of the inner peripheral body 6241 is smaller than the height of the outer peripheral portion 622, which can be adapted to the sealing structure 4.
In addition, the lower cover 62 further comprises a reinforcing portion 625 disposed between the inner peripheral portion 624 and the outer peripheral portion 622. The reinforcing portion 625 at least holds the second snap hook 623. The arrangement of the reinforcing portion 625 can effectively strengthen the second hook 623, thereby improving the limit effect of the second hook 623 on the blister case 41.
The reinforcing portion 625 is a reinforcing rib structure, and is disposed corresponding to the three second hooks 623.
In summary, the disclosed package for the capsule endoscope has a separate inner package 2, which comprises a base 21 and a cover 22 connected to the base 21, wherein the cover 22 is openably connected to the base 21, the cover 22 and the base 21 form a holding slot 25 for placing the capsule endoscope 8, so that the reliability of transportation of the capsule endoscope 8 is improved.
