Description

TECHNICAL FIELD

[0002] In the process of in-vitro diagnosis, biological samples (such as blood, urine or tissue, etc.) are usually dropped into a microfluidic disc for testing to obtain diagnostic information. Before testing with the microfluidic disc, the testing reagent can be processed by freeze-drying to form a freeze-dried ball, and the freeze-dried ball can be implanted into the disc hole on the microfluidic disc. The testing reagent processed by freeze-drying can be stably stored at room temperature, which not only prolongs the shelf life of the testing reagent and reduces the transportation and storage costs of the testing reagent, but also greatly simplifies the testing operation process by directly adding biological samples to the microfluidic disc when testing is needed. However, after implanting the freeze-dried ball into the microfluidic disc, the microfluidic disc needs to be protected to ensure its performance and reliability.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the present application more obvious, the following will describe the example embodiments according to the present application in detail with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the protection scope of the present application.

[0027] In the following description, a large number of details are provided so that the present application can be thoroughly understood. However, those skilled in the art can understand that the following description only exemplarily shows the preferred embodiments of the present application, and the present application can be implemented without one or more such details. In addition, in order to avoid confusion with the present application, some technical features known in the art are not described in detail.

[0028] In order to thoroughly understand the embodiments of the present application, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0029] An embodiment of the present application provides a waste film quick release assembly. The waste film quick release assembly can greatly simplify the operation steps of waste film cleaning, and effectively improve the convenience and efficiency of waste film cleaning. The following will introduce a waste film quick release assembly according to an embodiment of the present application in detail with reference to the drawings.

[0030] As Figures 1 to 4As shown, the waste film quick disassembly assembly includes a winding shaft 1 and a driving assembly 2. The winding shaft 1 includes at least two movably connected winding bodies. The driving assembly 2 drives the at least two winding bodies to move away from each other to be in a winding film state or to move close to each other to be in a disassembly film state. In the winding film state, a first winding shaft formed by the at least two winding bodies has a first outer peripheral wall with a first outer diameter, and the waste film is wound on the first outer peripheral wall. In the disassembly film state, a second winding shaft formed by the at least two winding bodies has a second outer peripheral wall with a second outer diameter, and the waste film is separated from the second outer peripheral wall. The first outer diameter is greater than the second outer diameter.

[0031] The winding shaft 1 can be in a cylindrical shape, and the at least two winding bodies can be movably connected to form the cylindrical winding shaft 1. The first winding shaft and the second winding shaft can represent different states of the winding shaft 1, and the at least two movably connected winding bodies can form the first winding shaft when moving away from each other and form the second winding shaft when moving close to each other.

[0032] When the driving assembly 2 drives the at least two movably connected winding bodies to move away from each other, the at least two movably connected winding bodies can form a first outer peripheral wall with a larger diameter, and at this time, the waste film can be wound on the first outer peripheral wall. When the driving assembly 2 drives the at least two movably connected winding bodies to move close to each other, the at least two movably connected winding bodies can form a second outer peripheral wall with a smaller diameter, and at this time, the second outer peripheral wall can form a movable space with the inner wall of the waste film, and thus the waste film can be disassembled from the winding shaft 1.

[0033] The waste film quick disassembly assembly of the utility model can make the at least two movably connected winding bodies of the winding shaft 1 move away from each other and form a first outer peripheral wall through the driving assembly 2, and at this time, the waste film can be wound on the first outer peripheral wall. When the winding of the waste film is completed, the driving assembly 2 can make the at least two movably connected winding bodies of the winding shaft 1 move close to each other and form a second outer peripheral wall, and at this time, the wound waste film can be separated from the second outer peripheral wall, and thus the waste film can be quickly and conveniently disassembled, greatly simplifying the operation steps of waste film cleaning and effectively improving the convenience and efficiency of waste film cleaning.

[0034] In some embodiments, as shown in Figure 5 As shown, the winding shaft 1 includes a movably connected first winding body 11 and a second winding body 12. On the movably connected first winding body 11 and the second winding body 12, one of the first winding body 11 and the second winding body 12 is provided with a sliding groove 3, and the other of the first winding body 11 and the second winding body 12 is provided with a sliding part 4 slidably connected with the sliding groove 3, so as to switch the winding shaft 1 between the winding film state and the disassembly film state.

[0035] The winding shaft 1 can be formed by the first winding body 11 and the second winding body 12, so that the connection structure of the winding shaft 1 can be simplified while ensuring that the winding shaft 1 can be switched between the film winding state and the film unwinding state.

[0036] The sliding part 4 can be a threaded part, such as a screw or a bolt, etc. Taking the screw as an example, when the sliding groove 3 is arranged on the first winding body 11 and the sliding part 4 is arranged on the second winding body 12, the screw can pass through the second winding body 12 and be in sliding connection with the sliding groove 3 on the first step part. The type of the sliding part 4 is not limited in the present application, and any device that can be in sliding connection with the sliding groove 3 can be used.

[0037] The operator can control the sliding distance of the sliding part 4 in the sliding groove 3 according to the actual use, so as to control the moving distance between the first winding body 11 and the second winding body 12, thereby improving the practicability of the winding shaft 1.

[0038] In the above embodiment, the sliding part 4 and the sliding groove 3 are used to achieve the movable connection between the first winding body 11 and the second winding body 12, which effectively simplifies the connection structure of the winding shaft 1 and reduces the manufacturing cost and failure rate of the winding shaft 1.

[0039] In some embodiments, the first winding body 11 and the second winding body 12 are both in arc-shaped structure, and the sliding groove 3 is in arc-shaped groove structure which is matched with the arc-shaped structure.

[0040] The cross-sectional shape of the first winding body 11 and the cross-sectional shape of the second winding body 12 can be arc-shaped, and specifically can be semicircular.

[0041] In the above embodiment, the sliding part 4 can move along the arc-shaped groove in an arc line, so that the first winding body 11 and the second winding body 12 can move relatively smoothly, and the winding shaft 1 can be switched between the film winding state and the film unwinding state smoothly, thereby effectively improving the flexibility and adaptability of the waste film quick disassembly assembly.

[0042] In some embodiments, as shown in Figures 2 to 4 The first winding body 11 and the second winding body 12 form a cylindrical body, and the first step part 111 is formed on the first winding body 11 and the second step part 121 is formed on the second winding body 12, the sliding groove 3 is located on the side of the first step part 111 facing the second step part 121, and the sliding part 4 is arranged on the second step part 121 and is in sliding connection with the sliding groove 3.

[0043] The first winding body 11 and the second winding body 12 can respectively have first step portions 111 and second step portions 121 that are staggered with each other, and the first step portions 111 and the second step portions 121 can be respectively provided with sliding grooves 3 and sliding portions 4. The sliding portions 4 and the sliding grooves 3 are connected in a sliding manner, so that the first winding body 11 and the second winding body 12 can move freely within a certain range, thereby realizing the mutual approach and separation of the first winding body 11 and the second winding body 12.

[0044] In the above embodiment, the first step portions 111 and the second step portions 121 that are staggered and attached to each other can effectively increase the contact area between the first winding body 11 and the second winding body 12. When the sliding portions 4 provided on the second step portions 121 slide along the sliding grooves 3 on the first step portions 111, the first step portions 111 and the second step portions 121 can always be attached to each other, thereby ensuring the stability of the movement of the first winding body 11 and the second winding body 12 when they are separated from or approached to each other.

[0045] In some embodiments, as shown in FIGS. 1 to 3, the driving assembly 2 includes a first driving member 21 and an inflation member 22. The first winding body 11 and the second winding body 12 enclose a receiving cavity, and the inflation member 22 is arranged in the receiving cavity. The first driving member 21 is configured to inflate the inflation member 22 or to deflate the inflation member 22 to exhaust the inflation member 22. When the inflation member 22 is inflated, the inflation member 22 abuts against the inner walls of the first winding body 11 and the second winding body 12 and pushes the first winding body 11 and the second winding body 12 away from each other. When the inflation member 22 is deflated, the inflation member 22 is separated from the inner walls of the first winding body 11 and the second winding body 12, so that the first winding body 11 and the second winding body 12 approach to each other. Figure 1 Figure 2 As shown in FIGS. 1 to 3, the driving assembly 2 includes a first driving member 21 and an inflation member 22. The first winding body 11 and the second winding body 12 enclose a receiving cavity, and the inflation member 22 is arranged in the receiving cavity. The first driving member 21 is configured to inflate the inflation member 22 or to deflate the inflation member 22 to exhaust the inflation member 22. When the inflation member 22 is inflated, the inflation member 22 abuts against the inner walls of the first winding body 11 and the second winding body 12 and pushes the first winding body 11 and the second winding body 12 away from each other. When the inflation member 22 is deflated, the inflation member 22 is separated from the inner walls of the first winding body 11 and the second winding body 12, so that the first winding body 11 and the second winding body 12 approach to each other.

[0046] The inflation member 22 can change in volume under the action of the first driving member 21, thereby driving the first winding body 11 and the second winding body 12 to move away from or approach to each other. Specifically, the first driving member 21 can inflate the inflation member 22 to make the inflation member 22 change in volume. At this time, the inflation member 22 can abut against the inner walls of the first winding body 11 and the second winding body 12 and push the first winding body 11 and the second winding body 12 away from each other, thereby making the winding shaft 1 in a film winding state. The first driving member 21 can also deflate the inflation member 22 to make the inflation member 22 change in volume. At this time, the inflation member 22 can be separated from the inner walls of the first winding body 11 and the second winding body 12, and the first winding body 11 and the second winding body 12 can approach to each other, thereby making the winding shaft 1 in a film unwinding state. The first driving member 21 can be a gas pump or other devices capable of making the inflation member 22 change in volume, which is not limited in the present application.

[0047] ​The inflatable member 22 can be made of a deformable material, so that a relatively large volume change can occur under the action of the first driving member 21, further facilitating the disassembly of the waste film.

[0048] In the above embodiment, through the cooperation of the first driving member 21 and the inflatable member 22, the first winding body 11 and the second winding body 12 can move away from or close to each other, so that the winding shaft 1 can be switched between the film winding state and the film disassembly state, while effectively simplifying the mechanical structure of the waste film quick disassembly assembly and optimizing the layout of the structure.

[0049] In some embodiments, as shown in Figure 1 The driving assembly 2 further includes a second driving member 23 connected to the inflatable member 22, and the second driving member 23 is used to drive the inflatable member 22 to rotate around its rotation axis in the film winding state.

[0050] In the film winding state, the volume of the inflatable member 22 can expand and abut against the inner wall of the winding shaft 1, and the second driving member 23 can drive the inflatable member 22 to rotate in the clockwise direction or the counterclockwise direction, thereby driving the winding shaft 1 sleeved outside the inflatable member 22 to rotate synchronously, so that the waste film can be wound around the winding shaft 1.

[0051] The second driving member 23 can include a transmission wheel 231 and a transmission belt 232, the transmission wheel 231 can be connected to the inflatable member 22, the transmission belt 232 is sleeved outside the transmission wheel 231, and the transmission belt 232 can drive the transmission wheel 231 to rotate, thereby driving the inflatable member 22 connected to the transmission wheel 231 to rotate. The second driving member 23 can also be a cylinder or other device capable of driving the inflatable member 22 to rotate, and the application does not limit the type of the second driving member 23.

[0052] In the above embodiment, the second driving member 23 can drive the inflatable member 22 to rotate around its rotation axis in the film winding state, so that the waste film can be quickly wound around the winding shaft 1, effectively improving the efficiency of the waste film quick disassembly assembly in winding the waste film, and further improving the practicality of the waste film quick disassembly assembly.

[0053] In some embodiments, as shown in Figures 1 to 3 The waste film quick disassembly assembly further includes a limiting member 5, and the outer side wall of the first winding body 11 and / or the second winding body 12 forms a limiting groove 13 in the direction of the rotation axis, and the limiting member 5 is clamped into the limiting groove 13, so as to fix the waste film on the first outer peripheral wall when the waste film is wound around the first outer peripheral wall.

[0054] The shape of the limiting piece 5 can be a rod shape. When the waste film is wound on the first outer peripheral wall for several turns, the rod-shaped limiting piece 5 can be clamped into the limiting groove 13 along the axial direction of the winding shaft 1, so that the waste film on the first outer peripheral wall and the first outer peripheral wall are firmly connected, and when the waste film continues to be wound on the first outer peripheral wall, the waste film and the winding shaft 1 are prevented from being separated, so that the winding shaft 1 cannot drive the waste film to rotate and wind.

[0055] In the above embodiment, the limiting piece 5 can clamp part of the waste film into the limiting groove 13, thereby firmly connecting the waste film and the first outer peripheral wall, effectively ensuring the firmness of the winding shaft 1 when winding the waste film, and further improving the practicability of the waste film quick release assembly.

[0056] In some embodiments, as shown in Figure 2 and Figure 3 , the limiting groove 13 is two, and the two limiting grooves 13 are symmetrically arranged along the radial direction of the winding shaft 1.

[0057] The shape of the limiting piece 5 can be U-shaped. When the two limiting grooves 13 are symmetrically arranged along the radial direction of the winding shaft 1, one U-shaped limiting piece 5 can be clamped into the two limiting grooves 13 along the axial direction of the winding shaft 1, thereby ensuring the convenience of use of the limiting piece 5.

[0058] In the above embodiment, the two symmetrically arranged limiting grooves 13 can fix the waste film on the first outer peripheral wall more firmly, and can also make the waste film wound on the first outer peripheral wall more evenly, avoid the waste film from being broken due to uneven force, and further improve the practicability and reliability of the waste film quick release assembly.

[0059] In some embodiments, as shown in Figure 1 , the waste film quick release assembly further comprises a winding roller 6, the winding roller 6 is sleeved on the winding shaft 1, and the two ends of the winding roller 6 respectively extend away from the winding shaft 1 to form a containing cavity 61 for containing the waste film.

[0060] The shape of the winding roller 6 can be cylindrical, and the two ends of the winding roller 6 respectively extend away from the winding shaft 1 to form a shielding part 62. By the shielding part 62, the position of the waste film on the winding shaft 1 can be limited when winding the waste film, so as to avoid the waste film from being offset during winding and causing the winding to be not firm. Moreover, the shielding part 62 can also increase the stability of the winding roller 6, so that the waste film is more uniform and stable when winding.

[0061] When the winding shaft 1 is in the film release state, the waste film in the containing cavity 61 can be separated from the second outer peripheral wall, so that the winding roller 6 and the waste film in the containing cavity 61 of the winding roller 6 can be removed together, thereby effectively improving the film release speed of the waste film quick release assembly.

[0062] In the above embodiment, the waste film can be quickly collected by the winding roller 6, avoiding the waste film from being scattered during winding process, effectively ensuring the cleanliness of the environment where the waste film quick disassembly assembly is located. Moreover, subsequent processing of the waste film can be greatly facilitated, effectively improving the efficiency and convenience of waste film processing.

[0063] According to another aspect of the present application, as shown in Figure 6 a film pasting device is also provided, which comprises a film pasting assembly 7 and the waste film quick disassembly assembly as described above, the film pasting assembly 7 is used for pasting film on a film-to-be-pasted piece, and conveying the waste film to the waste film quick disassembly assembly after the film pasting is completed.

[0064] The film pasting assembly 7 can be arranged upstream of the waste film quick disassembly assembly, and after the film pasting assembly 7 completes the film pasting on the film-to-be-pasted piece, the waste film generated can be conveyed to the waste film quick disassembly assembly, the waste film quick disassembly assembly can collect the waste film, and when the waste film accumulates to a certain amount, the waste film can be quickly and conveniently disassembled.

[0065] The film pasting device of the present application comprises the waste film quick disassembly assembly as described above, since the waste film quick disassembly assembly has the beneficial effects as described above, the film pasting device comprising the waste film quick disassembly assembly also necessarily has the beneficial effects as described above.

[0066] According to still another aspect of the present application, a freeze-dried ball implanting device is also provided, which comprises a feeding device, an implanting device and the film pasting device as described above, the feeding device and the implanting assembly are arranged in sequence upstream of the film pasting device.

[0067] The film-to-be-pasted piece can be specifically a microfluidic disc, the feeding device can be used for storing the microfluidic disc and conveying the microfluidic disc to the implanting device. The implanting device can implant freeze-dried balls into disc holes on the microfluidic disc, and after the implanting is completed, the microfluidic disc can be conveyed to the film pasting device, and then the film pasting operation is performed on the microfluidic disc by the film pasting device, so as to protect the microfluidic disc from damage by dust, moisture and chemical substances.

[0068] The freeze-dried ball implanting device of the present application comprises the film pasting device as described above, since the film pasting device has the beneficial effects as described above, the freeze-dried ball implanting device comprising the film pasting device also necessarily has the beneficial effects as described above.
