Description

Technical Field

[0001] The invention relates to a capsule collector filling device, in particular to a filling device comprising a clamping member and a switching member, belonging to the technical field of biomedicine. Background Art

[0002] As a self-service esophageal sampler, the sponge capsule has the advantages of less pain for the subjects and convenient sampling. The premise for the sponge capsule to be used is that the polyurethane sponge needs to be compressed and filled into the capsule. The capsule disintegrates when it encounters water and acidic environment in the stomach, and the sponge is released from the capsule to expand, and after contacting the esophageal wall, the esophageal epithelial exfoliated cells can be sampled.

[0003] As a material with strong shrinkage, sponge needs to be compressed to 1 / 10 of its own volume or even smaller before being put into a capsule. Generally, the sponge is stuffed into the capsule manually, which may cause the capsule to be contaminated and is not suitable for large-scale production.

[0004] The specification of Chinese invention patent CN 211609880 U discloses a filling device for a sponge capsule, the filling device includes a compression splint and a push plate, the compression splint includes two semi-cylindrical splints, one side of the semi-cylindrical splint is connected by a connector, the two semi-cylindrical splints are closed to form a cylindrical pipe, the push plate includes a stress rod, a connecting rod and a disc, the stress rod is connected to the disc through the connecting rod, one end of the compression splint after closing is provided with an opening for placing the connecting rod, and the push plate slides toward the opening of the connecting rod when under pressure. However, since the sponge is first subjected to a thrust moving toward the inside of the capsule in the semi-cylindrical pipe during the process of pushing the sponge into the capsule, the sponge subjected to the thrust is clumped, and the clumped sponge is easily deformed from the inside to the outside of the capsule under stress during the process of the push plate pushing the sponge into the capsule, thereby failing to achieve the desired effect. Summary of the invention

[0005] Purpose of the invention: In order to overcome the shortcomings of the prior art, the present invention provides a capsule collector filling device that can prevent the sponge from being contaminated and will not cause deformation of the capsule shell during the compaction process.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a capsule collector filling device, used to feed the sponge into the right capsule shell of the capsule collector, comprising a clamping member, an adapter and a fixing member, wherein: the clamping member comprises a clamping part and a compacting part, the clamping part and the compacting part are integrally connected, the clamping end of the clamping part and the compacting end of the compacting part are located at both ends of the clamping member, and the adapter is a channel structure with openings at both ends, wherein the left end of the adapter is a feed port and the right end is a discharge port, after the clamping member clamps the sponge, it enters the feed port of the adapter by rotating until it passes through the discharge port and reaches the right capsule shell, the clamping member is released, and the sponge is left in the right capsule shell, the clamping member moves in the direction of the right capsule shell away from the adapter, and when the entire clamping member is outside the adapter, the adapter is turned around, and the compacting member is extended into the channel of the adapter until it reaches the right capsule shell, and the sponge in the right capsule is compacted by the compacting member.

[0007] The fixing member includes a capsule fixing groove, a closing door, and a buckling mechanism. The capsule fixing groove is fixedly connected to the outer surface of the right end of the adapter. The capsule fixing groove includes an upper fixing groove and a lower fixing groove, and the upper fixing groove and the lower fixing groove are arranged opposite to each other up and down. The closing door is rotatably connected to the lower fixing groove, and the closing door is buckled with the upper fixing groove through the buckling mechanism.

[0008] The upper fixing groove is provided with a concave curved surface 1 that matches the right capsule shell, the lower fixing groove is provided with a concave curved surface 2 that matches the right capsule shell, and the closed door is provided with a concave curved surface 3 that matches the bottom of the right capsule. The concave curved surface 1, the concave curved surface 2, and the concave curved surface 3 surround a right capsule space that matches the right capsule shell. The function of the fixing groove is to clamp the right capsule shell and place the right capsule shell in the right capsule space. During the process of compacting the sponge in the right capsule shell, the compacting end will not cause deformation of the right capsule shell because the right capsule space matches the capsule shell. The capsule fixing groove is fixedly connected to the outer surface of the right end of the adapter. This arrangement makes the right capsule shell in a very stable state, thereby facilitating the continuity of the action of clamping the sponge and compacting the sponge. At the same time, the setting of the closed door facilitates the placement and removal of the right capsule shell.

[0009] The clamping part is used to clamp the sponge and rotate the sponge through the channel of the adapter to send the sponge into the right capsule shell.

[0010] The compacting part is used for compacting the sponge in the right capsule shell.

[0011] As a further improvement of the present invention, the clamping part is a pair of tweezers, and the diameter of the cross-section perpendicular to the axis of the tweezers when closed is smaller than the diameter of the feeding port. The compaction part has a cylindrical structure, and the diameter of the cross-section perpendicular to the axis of the compaction part is smaller than the inner diameter of the capsule. The clamping member is designed in the shape of long and thin tweezers. On the one hand, it is to facilitate deep insertion into the transition channel, and on the other hand, it is to make it easier to apply force when clamping the sponge. The tweezer-shaped part is composed of two corresponding tweezer walls. The thickness and width of the tweezer arms gradually decrease from the bottom of the tweezer arms towards the tips of the tweezer arms. This design is to cooperate with the channel of the adapter with a gradually decreasing radius. The diameter of the cross-section perpendicular to the axis of the compaction part is smaller than the inner diameter of the capsule, so that the compaction part can be inserted into the right capsule shell to compact the sponge.

[0012] As a further improvement of the present invention, the adapter includes an inlet channel, a transition channel, and an outlet channel connected in sequence. The shapes of the inlet channel and the outlet channel are both cylindrical, and the shape of the transition channel is a conical cylinder. The diameter of the conical cylinder gradually decreases from the end connected to the inlet channel towards the end connected to the outlet channel. The diameter of the outlet channel ≤ the diameter of the capsule. The sponge with a fluffy appearance first passes through the inlet channel and then reaches the transition channel. After the volume of the sponge is compacted again, it finally enters the right capsule shell through the outlet channel. The transition channel gradually decreases from the inlet channel towards the outlet channel. The purpose of this design is that during the process of the clamping member sending the sponge into the capsule, the volume of the sponge is compressed, making it easier to send the sponge into the right capsule shell.

[0013] As a further improvement of the present invention, the closing door is rotatably connected to the lower fixing groove through a rotating shaft. When the closing door rotates around the rotating shaft to the first extreme position, the closing door is in an open state. When the closing door rotates around the rotating shaft to the second extreme position, the closing door is detachably connected to the upper fixing groove through a fastening mechanism, and the closing door is in a closed state.

[0014] As a further improvement of the present invention, the fastening mechanism includes a magnet one and a magnet two. The magnet one is installed on the closing door, and the magnet two is installed on the upper fixing groove. The fastening mechanism includes a buckle, a magnetic buckle, an insertion buckle, etc. The setting of the fastening mechanism provides a stable spatial structure for the placement of the right capsule shell, preventing the right capsule shell from falling off the fixing member. The magnet one and the magnet two attract each other with opposite poles and have strong magnetism, so the closing door is tightly fastened to the upper fixing groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the capsule is fed into the transition channel, there is no need to worry about the sponge being contaminated due to manual operation. During the compaction process, due to the presence of the capsule fixing member, there is also no need to worry about the problem that the agglomerated sponge is likely to cause the capsule to expand and deform from the inside out under force, and it is very convenient to fix and pick up the capsule.

Detailed Embodiment

[0024] The present invention will be further clarified below in conjunction with the drawings and specific embodiments. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, various equivalent modifications made by those skilled in the art to the present invention fall within the scope defined by the appended claims of this application.

[0025] As Figures 1 to 6A capsule filler filling device is shown, comprising a clamping member 1, an adapter 2 and a fixing member 3, wherein the clamping member 1 comprises a clamping portion 11 and a compacting portion 12, wherein the clamping portion 11 and the compacting portion 12 are connected as one piece, wherein the clamping end 111 of the clamping portion 11 and the compacting end 121 of the compacting portion 12 are located at two ends of the clamping member 1, and the outer shape is an elongated tweezer shape, and the diameter of the cross section perpendicular to the axis of the tweezers when closed is smaller than the diameter of the feed port, wherein the tweezer-shaped component is composed of two corresponding tweezer walls, wherein the length of the tweezers is greater than the length of the adapter, and the inner side surfaces of the two tweezer arms form an elongated U-shaped surface, and during use, the sponge is clamped at one third of the tip of the tweezer arms. The thickness and width of the tweezer arms gradually decrease from the tip of the tweezers toward the direction away from the tip of the tweezers. The compacting end 121 is a cylindrical member, and the cross section diameter of the compacting portion 12 perpendicular to the axis of the compacting portion is smaller than the inner diameter of the capsule.

[0026] The adapter 2 is a channel structure with two ends open, wherein the left end of the adapter is a feed port 211, and the right end is a discharge port 231. The channels of the adapter are divided into an inlet channel 21, a transition channel 22, and an outlet channel 23, which are connected in sequence. The feed port 211 is arranged on the inlet channel 21, and the discharge port 231 is arranged on the outlet channel 23. The inlet channel 21 and the outlet channel 23 are cylindrical, and the transition channel 22 is a conical cylinder, and the diameter of the conical cylinder is determined by the connection between the inlet channel 21 and the outlet channel 23. One end of the channel 21 gradually decreases toward the end connected to the outlet channel 23, and the outer diameter of the outlet channel 23 is ≤ the inner diameter of the capsule. After the tip of the tweezer arm of the clamping part 11 clamps the fluffy sponge, it moves toward the outlet channel 23 through the inlet channel 21 until the sponge is delivered to the right capsule shell. The tweezer arm is released, and the tweezers move away from the right capsule shell. When the tweezers are outside the adapter 2, the clamping part 1 is turned around, and the sponge in the right capsule shell is compacted with the compacting part 12 of the clamping part 1.

[0027] like Figures 4 to 5As shown in the figure, the fixing member 3 includes a capsule fixing groove 31, a closing door 32, and a fastening mechanism 33. The capsule fixing groove 31 is fixedly connected to the outer surface of the right end of the adapter 2. The capsule fixing groove 31 is circumferentially connected to the outer surface of the right end of the adapter 2 in a snap connection manner. The capsule fixing groove 31 includes an upper fixing groove 311 and a lower fixing groove 312, and the upper fixing groove 311 and the lower fixing groove 312 are arranged opposite to each other up and down. The closing door 32 is rotatably connected to the lower fixing groove 312. A horizontal rotating shaft 331 connected to the closing door 32 is provided on the outer surface of the lower fixing groove 312. The closing door 32 rotates vertically with the horizontal rotating shaft 331 as the axis to realize the open or closed state of the fixing member 3. The closing door 32 is fastened and connected to the upper fixing groove 311 through the fastening mechanism 33. The fastening mechanism includes a first magnet 332 and a second magnet 333. The first magnet 332 is installed on the closing door, and the second magnet 333 is installed on the upper fixing groove 311. The first magnet 332 and the second magnet 333 attract each other with opposite poles.

[0028] The upper fixing groove 311 is provided with a concave curved surface 3111 matching the right capsule shell, the lower fixing groove 312 is provided with a concave curved surface 3121 matching the right capsule shell, and the closing door 32 is provided with a concave curved surface 321 matching the bottom of the right capsule. The concave curved surface 3111, the concave curved surface 3121, and the concave curved surface 321 enclose a right capsule space 34 matching the right capsule shell. When the right capsule shell is placed in the right capsule space 34 and the closing door 32 is rotated to a position close to the upper fixing groove 311, the first magnet 332 and the second magnet 333 are magnetically fastened together under the action of the magnetic field, thereby realizing the closed state of the right capsule space 34. When the right capsule shell needs to be removed, the closing door 32 is rotated away from the upper fixing groove, and the closing door is in an open state.

[0029] A method for filling a capsule collector: Open the fastening mechanism 33, rotate the closing door 32 with the rotating shaft 331 as the axis. When the closing door 32 rotates to the first limit position, place the right capsule shell into the right capsule space 34. Then rotate the closing door 32 with the rotating shaft 331 as the axis. When the closing door 32 rotates to the second limit position, fasten and connect the closing door 32 to the upper fixing groove 311 through the fastening mechanism 33. At this time, the opening of the right capsule shell contacts the discharge port 231 of the adapter 2.

[0030] Clamp the sponge through the clamping part 11, rotate the clamped sponge through the channel of the adapter 2 until the sponge is sent into the right capsule shell. Release the clamping part 11 and leave the sponge in the right capsule shell. Move the clamping part 11 in a direction away from the right capsule shell. When the entire clamping part 11 is outside the adapter 2, turn the adapter 2 around, insert the compaction part 12 into the channel of the adapter 2 until it reaches the right capsule shell, and compact the sponge in the right capsule with the compaction part 12.

[0031] The present invention can compact the sponge to the greatest extent without causing deformation or detachment of the capsule, and has the advantages of simple operation and low cost. The above description is only a preferred embodiment of the present invention. Within the scope of knowledge possessed by those of ordinary skill in the art, changes can also be made thereto. For example, in the above-mentioned embodiment, the sponge is clamped by tweezers and sent into the adapter. However, the present invention can also adopt other structures to achieve the feeding of the sponge into the adapter, such as using process parts like chopsticks, clips, pliers, etc. to achieve the clamping function. For example, in the mulberry tree embodiment, the fastening mechanism and magnetic adsorption fastening are used, but the present invention can also adopt other structures to achieve the fastening of the upper fixing groove and the closing door, such as using snap fasteners, magnetic fasteners, plug fasteners, etc.
