Description

Technical Field

[0001] This application relates to the field of fecal sampling equipment technology, and more particularly to a handheld fecal collector. Background Technology

[0002] Fecal testing is an important tool in clinical medicine and health screening, widely used in the diagnosis of digestive tract diseases, parasite detection, and gut microbiota analysis. The accurate sample size is crucial to the reliability of test results; too small a sample may lead to false negatives, while too large a sample may affect the reagent reaction ratio. Currently, medical institutions typically rely on patients to collect samples themselves, but due to the lack of quantitative capabilities, the sample size is difficult to control precisely, affecting the accuracy of subsequent laboratory tests.

[0003] Existing fecal collection devices mainly consist of structures such as collection rods, spoon-shaped containers, or disposable stool boxes. For example, some devices use collection spoons with graduated lines to visually estimate sample volume; other solutions use removable, sealed containers to directly hold samples, along with preservatives or buffer solutions to preserve them. Additionally, some designs employ spiral collection heads, which scrape feces by rotating and store them in a tube.

[0004] While the above methods can achieve basic data collection, none of them integrate a weighing module, making it impossible to accurately measure sample weight in real time. Relying on scale line estimation is susceptible to subjective judgment and sample morphology, resulting in significant errors; while relying solely on container volume ignores differences in fecal density, leading to a significant deviation between actual weight and required values. This inaccurate quantification can directly affect the mixing ratio of testing reagents or the effectiveness of centrifugation, thereby reducing the reliability of test results.

[0020] A push block is slidably disposed at the tail end of the spoon handle;

[0021] The traction rope has a first end connected to the locking block and a second end connected to the push block. It is used to pull the locking block away from the movable rod and slide it away from the limiting groove.

[0022] A reset component is used to drive the locking block to slide closer to the movable rod, so that the movable rod is embedded in the limiting groove.

[0023] Furthermore, the reset assembly includes a mounting plate and a reset spring. The mounting plate is located on the side of the locking block away from the movable rod, and the reset spring is a compression spring with its two ends connected to the locking block and the mounting plate, respectively.

[0024] Furthermore, the first end of the movable rod is provided with a slot for inserting the spoon head, and the slot is provided with a push-out mechanism for pushing the spoon head out of the slot.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0046] This application discloses a handheld fecal collector. (Refer to...) Figure 1 and Figure 2 Handheld fecal collectors include:

[0047] Spoon handle 1;

[0048] The spoon head 2 is detachably mounted on the front end of the spoon handle 1;

[0049] The weighing mechanism 3 is located between the spoon handle 1 and the spoon head 2, and is used to weigh the spoon head 2.

[0050] When collecting feces, a weighing mechanism 3 is set inside the spoon handle 1, so that the device has both collection and weighing functions. The spoon head 2 is detachable, so that the spoon head 2, which has collected the required weight of feces, can be placed into the sample detector dish for detection, thereby effectively solving the problem of difficulty in quantitatively collecting feces for detection.

[0051] Specifically, such as Figure 1 As shown, the spoon handle 1 includes a head section 11, a transition section 12, and a tail section 13. The head section 11 and the tail section 13 are arranged in parallel. The transition section 12 is located between the head section 11 and the tail section 13 and is inclined from the head end to the tail end, making the spoon handle 1 Z-shaped. The spoon head 2 is located at the front end of the head section 11. By holding the tail section 13, the user can increase the distance between their hand and the source of feces, reducing the possibility of contamination caused by the user's contact with feces.

[0052] To improve the stability of holding the spoon handle 1, a handle 5 is provided at the end of the tail section 13. The handle 5 is a straight rod perpendicular to the tail section 13.

[0053] Reference Figure 3 and Figure 4 The weighing mechanism includes a movable rod 31, a rotating shaft 32, a pressure sensor 33, a display screen 34, and a locking assembly 36.

[0054] The first end of the movable rod 31 protrudes from the front end of the spoon handle 1, and the second end is located inside the spoon handle 1. The rotating shaft 32 is fixed inside the spoon handle 1. Figure 3 As shown. The movable rod 31 is sleeved on the rotating shaft 32 and can rotate around the rotating shaft 32. The front end of the spoon handle 1 can be set to be fully open or half open. In this embodiment, the front end of the spoon handle 1 is set to be half open to limit the movable rod 31. The limit position is when the movable rod 31 is parallel to the front part of the spoon handle 1. When it is in this position, the movable rod 31 can only rotate in the counterclockwise direction.

[0055] The pressure sensor 33 is fixed on the inner top wall of the front section of the spoon handle 1. The movable rod 31 has a protrusion 35 on the side of the rotating shaft 32 away from the spoon head 2. The protrusion 35 is hemispherical. When the movable rod 31 rotates, the protrusion 35 touches the pressure sensor 33, which can make the pressure sensor 33 generate an electrical signal.

[0056] The display screen 34 is mounted on the top surface of the first section 11 of the spoon handle 1, and includes a housing, screen, zeroing button, power button, processor, and battery (not shown in the figure). The processor is electrically connected to the pressure sensor 33 and the screen. After receiving the electrical signal from the pressure sensor 33, the processor converts the electrical signal into a weighing value according to the lever principle and displays it on the screen (the principle is based on existing technology and will not be elaborated here), allowing the user to read the weighing value at any time. The battery is a button battery, which is detachably mounted on the housing for easy replacement, thus enhancing the functionality of the weighing mechanism 3. The power button allows for easy screen shutdown to save power. The zeroing button avoids the influence of different weights of the spoon heads 2 on the measurement data, significantly reducing measurement errors and making the value displayed on the display screen 34 as close as possible to the individual masses on the spoon heads 2, further improving the accuracy of the weighing value.

[0057] The locking component 36 is located inside the spoon handle 1 and can lock the movable rod 31. When collecting feces, the movable rod 31 can be locked to prevent it from swinging randomly, which would result in a poor experience when collecting feces. It can also reduce the number of times the movable rod 31 contacts the pressure sensor 33 and improve its service life.

[0058] Specifically, such as Figure 3 and Figure 4 As shown, the locking component 36 includes a locking block 361, a pushing block 362, a traction rope 363, and a reset component.

[0059] The locking block 361 has the same dimensions as the internal cross-section (the cross-section perpendicular to the length direction of the first segment 11, hereinafter the same) of the first segment 11 of the spoon handle 1. The locking block 361 is slidably disposed inside the spoon handle 1 in the direction of approaching or moving away from the movable rod 31. A limiting groove 3611 is provided on the side of the locking block 361 near the movable rod 31, and the cross-section of the limiting groove 3611 has the same dimensions as the second end of the movable rod 31. In order to facilitate the insertion of the movable rod 31 into the limiting groove 3611, a chamfer is provided at the opening of the limiting groove 3611, that is, the limiting groove 3611 is Y-shaped, and the range of its chamfer is larger than the range of motion of the second end of the movable rod 31, so as to facilitate guiding the movable rod 31 into the limiting groove 3611.

[0060] The traction rope 363 is used to pull the locking block 361 away from the movable rod 31 to move, and the reset component is used to drive the locking block 361 to move closer to the movable rod 31, so that the movable rod 31 is inserted into or disengaged from the limiting groove 3611, thereby realizing the locking and releasing of the movable rod 31.

[0061] Regarding the drive mechanism of the traction rope 363, such as Figure 4As shown, the cross-section of the push block 362 is the same as the internal cross-section of the tail section 13 of the spoon handle 1. A push groove 131 is formed on the top surface of the tail section 13. An arc-shaped protrusion is integrally formed on the top surface of the push block 362. The arc-shaped protrusion is positioned as a concave arc surface, facilitating the user to slide the push block 362 with their fingers. The second end of the traction rope 363 is fixedly connected to the push block 362. By driving the push block 362 to slide towards the handle 5, the locking block 361 can be moved away from the movable rod 31 via the traction rope 363.

[0062] Regarding the reset component, such as Figure 3 As shown, the reset assembly includes a mounting plate 365 and a reset spring 364. The mounting plate 365 is welded and fixed to the spoon handle 1 and is located on the side of the locking block 361 away from the movable rod 31. One end of the reset spring 364 abuts against the locking slide bar, and the other end abuts against the mounting plate 365. When the traction rope 363 pulls the locking slider away from the movable rod 31, the reset spring 364 is compressed. When the user releases the push block 362, the reset spring 364 releases its own elastic potential energy, causing the locking slider to move closer to the movable rod 31, so that the movable rod 31 is inserted into the limiting groove 3611, thereby limiting the movable rod 31. The operation is convenient and it is easy to unlock or lock the movable rod 31 at any time.

[0063] On the other hand, referring to Figure 3 and Figure 5 The first end of the movable rod 31 is provided with a slot 311 for inserting the spoon head 2. The opening of the slot 311 is located at the end of the movable rod 31. Since the feces cover a wide area when the spoon head 2 is collecting feces, in order to remove the spoon head 2 without contact, in this embodiment, a pushing mechanism 4 is provided inside the slot 311 to push the spoon head 2 away from the slot 311.

[0064] Specifically, such as Figure 5 As shown, the push-off mechanism 4 includes a push rod 41, a push-off spring 42, and a control assembly.

[0065] The push rod 41 is a T-shaped rod, including a head 411 and a tail 412, wherein the cross-sectional dimension of the head 411 is smaller than that of the tail 412. The slot 311 is a T-shaped slot, including a slot opening 3111 and a slot bottom 3112, wherein the cross-sectional dimension of the slot opening 3111 is smaller than that of the slot bottom 3112. Furthermore, the cross-sectional dimensions of the head 411 and the slot opening 3111 are the same, and the cross-sectional dimensions of the tail 412 and the slot bottom 3112 are the same, allowing the head 411 to slide along the slot opening 3111 and the tail 412 to slide along the slot bottom 3112. The tail end of the spoon head 2 is interference-fitted with the slot opening 3111 of the slot 311, thus ensuring its stable fixation within the slot 311.

[0066] A push-off spring 42 is disposed between the push rod 41 and the bottom wall of the slot bottom 3112, for driving the push rod 41 to slide toward the opening end of the slot 311. A control component is disposed at the first end of the movable rod 31 for locking or releasing the push rod 41. The T-shaped slot 311, in conjunction with the T-shaped push rod 41, can prevent the push rod 41 from disengaging from the slot 311 under the push of the push-off spring 42. Furthermore, the length of the rod head 411 is the same as the length of the slot opening 3111, ensuring that the push rod 41 can completely push the spoon head 2 away from the slot 311.

[0067] Furthermore, the principle of the control component can be referenced from the telescopic mechanism of a manually retractable umbrella handle. Specifically, the control component includes a locking block 43 and a locking spring 44. A groove is provided on the tail 412 of the push rod 41, with the opening of the groove facing upwards. The locking block 43 is slidably disposed along the groove. An clearance hole 312 for the locking block 43 to pass through is provided on the top surface of the first end of the movable rod 31. One end of the locking spring 44 is welded and fixed to the bottom of the groove, and the other end is welded and fixed to the bottom wall of the locking block 43. As the push rod 41 moves, when the locking block 43 is aligned with the clearance hole 312, the locking spring 44 pushes the locking block 43 through the clearance hole 312 and protrudes from the surface of the movable rod 31, thereby restricting the sliding of the push rod 41 and locking the push rod 41.

[0068] When fecal collection is required, insert the spoon head 2 into the slot 311. The spoon head 2 pushes the push rod 41 to slide, and the push spring 42 is compressed until the locking block 43 is aligned with the clearance hole 312. The locking spring 44 pushes the locking block 43 through the clearance hole 312 to lock the push rod 41, completing the one-time installation of the spoon head 2. After the fecal sampling is completed, press the locking block 43 so that the locking block 43 is fully embedded in the slide groove. The push rod 41 slides under the drive of the push spring 42, pushing the spoon head 2 away from the slot 311, realizing non-contact disassembly of the spoon head 2 and reducing the possibility of fecal contamination.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
