DETAILED DESCRIPTION

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0053] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0054] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0055] In the description of the present invention, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0059] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0060] Figure 1-Figure 5 The first sample collection device 100 provided in this embodiment is shown;

[0061] Figures 6-10 A second sample collection device 100 provided in this embodiment is shown.

[0062] Figures 1-10 In this embodiment, a sample collection device 100 is provided, which includes a cover body 10, a filter structure 20 and a bottle body 30 arranged in sequence. The cover body 10 is provided with a collection hole 11, and the bottle body 30 is provided with a suction hole 31. The filter structure 20 and the cover body 10 are movably arranged so that when the filter structure 20 is located between the cover body 10 and the bottle body 30, the suction hole 31 is connected to the collection hole 11 through the filter structure 20. When the filter structure 20 is not completely located between the cover body 10 and the bottle body 30, the sample 300 ( Figure 14) can be removed.

[0063] Generally, the sample collection device 100 is often used to collect and extract samples from the human body. For example, during an endoscopic operation, the collection port 11 can be connected to the endoscope's forceps channel, or connected to the endoscope's forceps channel through other pipes, or directly extended into the patient's body through other pipes. The suction port 31 is connected to a suction device (e.g., a vacuum generator). Under direct endoscope observation, the suction device is turned on and, through suction, polyps and other samples within the patient's body are drawn through the forceps channel and collection port 11 onto the filter structure 20, where the sample is collected by the filter structure 20.

[0064] The filter structure 20 has several filter holes that can realize sample filtering. Under the suction action of the suction device, the fluid sucked out from the patient body passes through the filter structure 20, and the sample is intercepted by the filter structure 20, so that the sample remains on the filter structure 20, while other impurities are discharged.

[0065] The filter structure 20 and the cover body 10 are movably arranged, so that in a certain state (installed for normal collection and extraction process), the filter structure 20 is located between the cover body 10 and the bottle body 30, and normal sample collection can be achieved. In a certain state (when the sample needs to be taken out, the filter structure 20 is moved out of the cover body 10), the filter structure 20 is not completely located between the cover body 10 and the bottle body 30, so that the sample in the filter structure 20 can be quickly taken out, which greatly improves the sample collection efficiency and effectively saves the doctor's time.

[0066] Combine Figure 1 ,by Figure 1 The relative position of Figure 1 The collecting hole 11 shown in the figure is located at the top of the cover body 10. Optionally, the collecting hole 11 can also be located on the side of the cover body 10. Similarly, the suction hole 31 is located at the bottom of the bottle body 30. Optionally, the suction hole 31 can also be located on the side of the bottle body 30.

[0067] Combine Figure 1-Figure 5 In the first sample collection device 100 , the filter structure 20 is rotatably connected to the cover 10 .

[0068] Similar to a rotary drawer structure, rotation can determine whether the filter structure 20 is located between the cover 10 and the bottle body 30. This method ensures that during the normal sample removal process, the filter structure 20 is always located on the cover 10 (bottle body 30). The entire operation process is more convenient, installation and disassembly are also convenient, and positioning is also more convenient.

[0069] In this embodiment, the sample collection device 100 further includes a first fastener 40 , through which the cover 10 is connected to the filter structure 20 . The filter structure 20 is rotatably connected to the cover 10 around the axis of the first fastener 40 .

[0070] It can be understood that the cover body 10 and the filter structure 20 are detachably connected and can be installed and removed by the first fastener 40. At the same time, the first fastener 40 is also the rotation axis of the cover body 10, making the overall structure more compact.

[0071] Combine Figure 4 and Figure 5 In this embodiment, the cover body 10 is provided with a first hole 12, the filter structure 20 is provided with a second hole 21, the bottle body 30 is provided with a third hole 32, and the first fastener 40 includes a first bolt 41 and a first nut 42. The first bolt 41 is used to pass through the first hole 12, the second hole 21 and the third hole 32 and then be threadedly connected with the first nut 42.

[0072] It can be understood that the cover body 10, the filter structure 20 and the bottle body 30 are all detachably connected via the first fastener 40, and the overall structure is relatively compact.

[0073] The first hole 12, the second hole 21, and the third hole 32 can all be smooth holes, or some can be threaded holes. It should be noted that the third hole 32 is a square hole, and the end of the first bolt 41 has a square cross-section. This allows the first bolt 41 to be prevented from rotating under load when the filter structure 20 rotates relative to the cover 10 (bottle body 30).

[0074] In this embodiment, there are multiple filter structures 20 , and the multiple filter structures 20 are connected by a connecting structure 50 . The second hole 21 is opened in the connecting structure 50 .

[0075] Specifically, the number of the filtering structures 20 is at least two, and the at least two filtering structures 20 are symmetrically arranged relative to the connecting structure 50 .

[0076] Specific, combined Figure 4 The number of the filtering structures 20 is two, and the two are symmetrically distributed at 180°. The number can also be three, and the three are symmetrically distributed at 120°. The number can also be four, and the four are symmetrically distributed at 90°. Similarly, the number can also be five, six or more.

[0077] by Figure 4The relative positions in the figure are introduced as follows. At this time, the filter structure 20 on the left is located between the cover body 10 and the bottle body 30. The filter structure 20 can realize sample collection. The filter structure 20 on the right is located in the external area between the cover body 10 and the bottle body 30. When the filter structure 20 on the left has collected the sample and needs to be taken out, the filter structure 20 is rotated to exchange the positions of the two filter structures 20. In this way, the filter structure 20 without the sample is located between the cover body 10 and the bottle body 30, and the filter structure 20 with the sample is not located between the cover body 10 and the bottle body 30 at all. At this time, the sample can be taken away by tweezers (or other tools).

[0078] It should be noted that the number of the filter structures 20 may also be three, four or more.

[0079] In this embodiment, the cover body 10 is further provided with a fourth hole 13, the bottle body 30 is further provided with a fifth hole 33, and the sample collection device 100 further includes a second fastener 60, the second fastener 60 includes a second bolt 61 and a second nut 62, and the second bolt 61 is used to pass through the fourth hole 13 and the fifth hole 33 and then be threadedly connected with the second nut 62.

[0080] The second fastener 60 can securely connect the cover 10 and the bottle 30, preventing relative displacement between the cover 10 and the bottle 30 during use, which could affect airtightness. It should be noted that the fourth hole 13 and the fifth hole 33 can be smooth holes or partially threaded holes.

[0081] According to the first sample collection device 100 provided in this embodiment, the installation process of the sample collection device 100 is as follows:

[0082] Place the cover body 10, the filter structure 20 and the bottle body 30 in sequence so that the first hole 12, the second hole 21 and the third hole 32 are aligned, and the first bolt 41 is passed through the first hole 12, the second hole 21 and the third hole 32 in sequence, and then connected to the first nut 42 and tightened. At the same time, the second bolt 61 is passed through the fourth hole 13 and the fifth hole 33 in sequence, and then connected to the second nut 62 and tightened.

[0083] It should be noted that the cooperation between the cover body 10 , the filter structure 20 and the bottle body 30 requires certain airtightness requirements. For example, when the suction reaches a negative pressure of 20 KPa, the filter structure 20 can still rotate relative to the cover body 10 .

[0084] When taking samples, the suction device can be turned off first, and then the filter structure 20 can be rotated to take out the sample contained in the filter structure 20. At the same time, another filter structure 20 without a sample can be moved between the cover body 10 and the bottle body 30 to continue collecting other samples.

[0085] Combine Figures 6-10In the second sample collection device 100 , the filter structure 20 is slidably disposed between the cover 10 and the bottle body 30 .

[0086] Similar to a pull-out drawer structure, when it is necessary to collect samples, the filter structure 20 is inserted between the cover 10 and the bottle 30, and the cover 10, the filter structure 20 and the bottle 30 are relatively fixed to achieve normal sample collection. After the collection is completed, the filter structure 20 is pulled out to separate the filter structure 20 from the cover 10 (bottle 30). At this time, the sample can be taken away with tweezers (or other tools), or directly poured into the collection bottle 200 ( Figure 12-14 shown in ).

[0087] Combine Figure 9 and Figure 10 In this embodiment, the outer wall of the bottle body 30 is connected to an enclosure 34 , and the enclosure 34 is used to limit the filter structure 20 between the cover body 10 and the bottle body 30 .

[0088] The provision of the enclosure 34 facilitates the insertion and positioning of the filter structure 20 so that it is located exactly between the cover 10 and the bottle body 30 and a certain degree of airtightness can be ensured.

[0089] In this embodiment, there are two enclosure members 34 , and a first notch 35 and a second notch 36 are formed between the two enclosure members 34 . The filter structure 20 can be separated from the cover body 10 through the first notch 35 and / or the second notch 36 .

[0090] by Figure 9 As an introduction to the relative positions in the figure, the spacing of the first notch 35 is smaller than the spacing of the second notch 36, so the filter structure 20 is inserted into the second notch 36 (from right to left) and is positioned under the action of the enclosure 34. When taking it out, the operator can put his hand into the first notch 35 and push the filter structure 20 (from left to right), and the filter structure 20 can be pushed out through the second notch 36.

[0091] In this embodiment, the enclosing member 34 abuts against the cover body 10 to maintain a fixed distance between the cover body 10 and the bottle body 30 .

[0092] The enclosure 34 can maintain a stable connection between the cover body 10 and the bottle body 30 to a certain extent, so that the cover body 10 and the bottle body 30 are not easily displaced. At the same time, in order to ensure airtightness, a protrusion can be set at the end of the enclosure 34, and a groove can be set at the end of the cover body 10 so that the protrusion is stuck in the groove, which can further increase the stability of the structure. At the same time, in order to improve airtightness, a sealing strip can be set in the groove.

[0093] In this embodiment, the sample collection device 100 further includes a third fastener 70 , and the cover 10 and the bottle body 30 are connected via the third fastener 70 .

[0094] Specifically, there are two third fasteners 70 , and the cover body 10 and the bottle body 30 can be stably connected by the two third fasteners 70 .

[0095] In this embodiment, the cover body 10 is provided with a seventh hole 14, the bottle body 30 is provided with an eighth hole 37, and the third fastener 70 includes a third bolt 71 and a third nut 72. The third bolt 71 is used to pass through the seventh hole 14 and the eighth hole 37 and then connect with the third nut 72.

[0096] It should be noted that the seventh hole 14 and the eighth hole 37 can be smooth holes, or partially threaded holes.

[0097] According to the second sample collection device 100 provided in this embodiment, the installation process of the sample collection device 100 is as follows:

[0098] Place the filter structure 20 between the cover body 10 and the bottle body 30 so that the seventh hole 14 and the eighth hole 37 are aligned, and then pass the third bolt 71 through the seventh hole 14 and the eighth hole 37 in sequence and connect with the third nut 72 and tighten.

[0099] It should be noted that when it is necessary to remove the sample, the suction device can be turned off first, the filter structure 20 can be pushed out, and the filter structure 20 can be turned upside down into the collection bottle 200 to separate the sample. The filter structure 20 without the sample can then be inserted between the cover 10 and the bottle body 30 through the second notch 36.

[0100] Combine Figure 11 , Figure 11 The third sample collection device 100 shown in FIG. 1 shares most of its structure with the second sample collection device 100 described above, differing in that a clamping head 73 is provided at one end of the third fastener 70, and a notch 74 is provided along the axial direction of the third fastener 70. The third fastener 70 is similar to an expansion bolt, and the clamping head 73 is tightened by passing through the eighth hole 37. Specifically, when the clamping head 73 is located in the eighth hole 37, the spacing between the notches 74 decreases, and the size of the clamping head 73 shrinks. When the clamping head 73 extends out of the eighth hole 37, the size of the clamping head 73 is restored, locking the bottle body 30 and achieving tightening.

[0101] The other end of the third fastener 70 can be fixedly connected to the cover body 10 or detachably connected. For example, the third fastener 70 first passes through the seventh hole 14 on the cover body 10 and then passes through the eighth hole 37 on the bottle body 30 to achieve relative fixation between the cover body 10 and the bottle body 30.

[0102] It is understandable that the cover 10 and the bottle body 30 can be fixed by bolts, screws, pins, etc., or by snapping, welding, gluing, etc. Theoretically, any method that can fix the two in the existing technology can be used.

[0103] It should be noted that any of the above-mentioned sample collection devices 100 can be selected according to actual needs.

[0104] Combine Figures 1-11 In the above embodiment, a sealing member 80 is provided on a side of the filter structure 20 close to the cover body 10 , and / or a sealing member 80 is provided on a side of the filter structure 20 close to the bottle body 30 .

[0105] By providing the sealing member 80 , the airtightness of the cover body 10 , the filter structure 20 and the bottle body 30 can be further improved.

[0106] For example, combined with Figure 4 , Figure 4 The seal 80 shown in FIG is located above the filter structure 20 and is used to seal the gap between the cover 10 and the filter structure 20 . When the seal 80 is located below the filter structure 20 , it can seal the gap between the filter structure 20 and the bottle body 30 .

[0107] Combine Figures 1-11 In the above embodiment, the sample collection device 100 further includes a light source 90 , which emits light toward the filter structure 20 .

[0108] By providing a light source 90, the doctor can clearly see the sample even in a dimly lit room. The light source 90 can be an LED lamp with its own battery, switch, etc. It can be located inside the cover 10 or inside the bottle 30. It can also be located outside.

[0109] Combine Figures 1-11 In the above embodiment, the light source 90 is connected to the bottle body 30 .

[0110] Specifically, the outer wall of the bottle body 30 is provided with a mounting hole 38 , and the light source 90 is detachably inserted into the mounting hole 38 .

[0111] The light source 90 can be easily installed and removed through the mounting hole 38. In other embodiments, the light source 90 and the bottle body 30 can also be bonded or fixedly connected.

[0112] Combine Figures 1-11 In the above embodiment, the bottle body 30 is provided with a transparent portion made of a transparent material, and the light source 90 is connected to the transparent portion and is located outside the bottle body 30 .

[0113] Through the transparent area, even if the light source 90 is located outside the bottle body 30, light can still be directed to the sample, which is convenient for the doctor to observe.
