[0020] like Figure 1-4 As shown, a feces specimen collector in the present application comprises a cup body 1, a cup cover 2, a sampling spoon 3 and a movable component 4, wherein the cup cover 2 is detachably connected to the cup body 1, the sampling spoon 3 is connected to the cup cover 2 via the movable component 4, and the movable component 4 is telescopically movable, thereby driving the sampling spoon 3 to telescopically move, thereby compensating for the length of the sampling spoon 3, so as to facilitate feces collection for toilet bowls with a deeper depth; and when collection is not needed or is completed, the cup cover 2 and the cup body 1 can be stored as a whole, which is convenient to store and can effectively isolate odors.
[0021] Among them, reference Figure 1 and Figure 2 The cup body 1 has an opening at the top, which can be used to hold the collected feces specimen. The cup body 1 is made of a transparent material, and a scale line 11 is arranged on the cup body 1. Specifically, the cup body 1 can be made of a transparent glass material or a transparent plastic material, so that the color and properties of the specimen can be observed through the cup body 1, and the odor can be prevented from leaking through the cup body 1.
[0022] refer to Figure 1 and Figure 2 The cup cover 2 is detachably connected to the open end of the cup body 1. Specifically, the inner side of the cup cover 2 is provided with an inner screw thread, and the open end of the cup body 1 is provided with an outer screw thread. The cup cover 2 can be detachably connected to the cup body 1 through the meshing of the inner screw thread and the outer screw thread. After the cup cover 2 is connected to the cup body 1, it can form a whole, and the interior of the cup body 1 can be sealed and isolated, thereby effectively isolating the odor generated by the fecal specimen.
[0023] refer to Figure 1 and Figure 4The sampling spoon 3 is connected to the cup cover 2 through the movable component 4, and can move with the movable component 4, thereby being able to compensate for the length of the sampling spoon 3, so as to facilitate the collection of fecal specimens from a deep toilet. Furthermore, a spike portion 31 is provided at the front end of the sampling spoon 3, and the spike portion 31 provided at the front end of the sampling spoon 3 facilitates the collection of fecal specimens of hard and dry feces.
[0024] refer to Figure 1 and Figure 4 The movable assembly 4 includes a fixed cylinder 41, a rotating cylinder 42 and a sliding member 43. The fixed cylinder 41 has openings at both ends, and the upper end is fixedly connected to the lower end of the cup cover 2. A spiral groove 411 is provided on the side wall of the fixed cylinder 41. Further, two groups of spiral grooves 411 are provided, and the two groups of spiral grooves 411 rotate in the same direction, and the two groups of spiral grooves 411 are respectively located on the opposite sides of the side wall of the fixed cylinder 41.
[0025] The rotating cylinder 42 is open at both ends, and the rotating cylinder 42 is rotatably disposed in the fixed cylinder 41, and a linear groove 421 is disposed on the side wall of the rotating cylinder 42. Further, two groups of linear grooves 421 are disposed, and the two groups of linear grooves 421 face the same direction, and the two groups of spiral grooves 411 are respectively located on opposite sides of the side wall of the rotating cylinder 42. Optionally, a transverse groove connected to the linear groove 421 is disposed at the lower end of the linear groove 421, and the direction of the transverse groove is the same as the rotation direction of the spiral groove 411.
[0026] Pins 431 are provided on both ends of the side wall of the sliding member 43. The sliding member 43 is slidably disposed in the rotating cylinder 42, and the pins 431 at both ends can be inserted into the linear groove 421 and the spiral groove 411 at the same time. The sampling spoon 3 is fixedly disposed at the lower end of the sliding member 43. When the sliding member 43 slides to the lowermost end and extends out of the rotating cylinder 42, the pins 431 can be engaged in the transverse groove to prevent the sliding member 43 from being forced to shrink and move inward due to the pressure on the sampling spoon 3 during sampling.
[0027] The pins 431 at both ends of the sliding member 43 are simultaneously inserted into the linear groove 421 provided on the rotating cylinder 42 and the spiral groove 411 provided on the fixed cylinder 41, and then by rotating the rotating cylinder 42, due to the restriction of the spiral groove 411, the sliding member 43 can be driven to slide up and down in the rotating cylinder 42, so that the end of the sliding member 43 connected to the sampling spoon 3 can extend out of the rotating cylinder 42, or be stored in the rotating cylinder 42, thereby compensating for the length of the sampling spoon 3, so as to facilitate the feces collection of a deeper toilet bowl.
[0028] Furthermore, a rotating handle 44 is provided at one end of the rotating cylinder 42, and a through hole 21 is provided at the upper end of the cup cover 2, and the rotating handle 44 can pass through the through hole 21 and extend out of the cup cover 2. The rotating cylinder 42 can be driven to rotate by simply rotating the rotating handle 44 extending out of the cup cover 2, thereby controlling the sampling spoon 3 inside the cup cover 2 to slide up and down.
[0029] refer to Figure 3 The rotating handle 44 is provided with a rotating groove 441, and the cup cover 2 is clamped in the rotating groove 441, which can prevent the rotating cylinder 42 from being separated from the fixed cylinder 41. A sealing ring 442 is provided in the rotating groove 441, and the side wall of the through hole 21 abuts against the sealing ring 442, so that the rotating handle 44 can seal the through hole 21 at the upper end of the cup cover 2 to prevent the odor from leaking and overflowing.
[0030] Furthermore, the upper end of the sliding member 43 is open, and a cavity 432 is formed inside. A plurality of side holes communicating with the cavity 432 are arranged at intervals on the side wall of the sliding member 43 , and the side holes are covered and connected with a filter screen 433 .
[0031] A slot 443 is provided at the lower end of the rotating handle 44. After the sliding member 43 slides upward, the open end can be engaged in the slot 443. A liquid intake port 444 communicating with the cavity 432 is provided at the upper end of the rotating handle 44. A rubber plug 45 is detachably provided on the liquid intake port 444.
[0032] refer to Figure 4 When the open end of the sliding member 43 is engaged in the card slot 443, the cavity 432 inside the sliding member 43 can only exchange substances through the filter 433, that is, the stool specimen in the cup body 1 is mixed with the pre-installed preservation solution, and then flows into the cavity 432 after being filtered through the filter 433, so that the substances in the stool specimen can be dissolved in the liquid, and the solid and liquid can be separated.
[0033] At the same time, a liquid sampling port 444 connected to the cavity 432 is reserved at the upper end of the rotating handle 44, and the sampling port is sealed by a rubber stopper 45, which not only meets the requirements of airtight storage and pre-filled storage liquid, but also facilitates liquid collection and meets the requirements of conventional feces detection and feces molecular detection.
[0034] The rubber stopper 45 and the liquid extraction port 444 are interference fit. When extracting liquid, a liquid suction puncture needle can be used to directly pierce the rubber stopper 45 to extract liquid. After the liquid extraction is completed, the liquid suction puncture needle is pulled out and the puncture hole on the rubber stopper 45 can be closed automatically.
[0035] Therefore, a stool sample collector in the present application can be used for routine testing. Since a seal is adopted between the cup body 1 and the cup cover 2, odor can be effectively isolated, and the length of the sampling spoon 3 can be compensated through the movable component 4, so as to facilitate the collection of stool samples for deeper toilet bowls.
[0036] Secondly, a stool specimen collector in the present application can also be used for molecular detection. The cup cover 2 and the cup body 1 are sealed, so the preservation liquid can be pre-installed in the cup body 1, thereby ensuring that the sample is kept in the preservation liquid from the time the user completes sampling until it is sent to the pre-testing process. In addition, except for the filter net 433 that can exchange substances between the cavity 432 and the inside of the cup body 1, other positions are sealed, which can meet the requirements of molecular detection pre-treatment filtration, and thus meet the requirements of molecular detection pre-treatment.
[0037] Finally, the use process of a stool specimen collector in the present application is as follows: when collecting samples, the cup cover 2 is separated from the cup body 1, and the rotating handle 44 at the upper end of the cup cover 2 is rotated to drive the rotating cylinder 42 to rotate, so that the sampling spoon 3 arranged at the lower end of the sliding member 43 can slide downward and extend along with the sliding member 43, thereby compensating for the length of the sampling spoon 3, so as to facilitate the collection of stool specimens for toilet bowls with deeper depths; after the collection is completed, the rotating handle 44 is rotated in the opposite direction, so that the sampling spoon 3 can shrink along with the sliding member 43, and the cup cover 2 is connected to the cup body 1 to form a whole, thereby effectively isolating the odor generated by the stool specimen in the cup body 1.
[0038] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present utility model should be within the protection scope of the present utility model.
