AI Technical Summary
Existing fecal samplers have problems with sample leakage and environmental pollution during the sampling process. In particular, the clamp cannot effectively cover the sampling spoon, and the clamp and sampling spoon are prone to bending and deformation, causing the sample to be thrown out.
A fecal sampler was designed, comprising a cup lid, a cup body, a sampling spoon, and a clamp. The clamp is rotatably mounted on the flange of the cup lid, and a clamping block is provided at the lower end of the clamp to cover the opening of the sampling spoon. The clamp and the sampling spoon are detachably connected to ensure complete sample collection and prevent deformation.
It prevents sample leakage and environmental pollution during the sampling process. The clamps and sampling spoons are not easily deformed, ensuring that the samples are collected completely and are easy to handle.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to a stool sampler. Background Technology
[0002] Chinese utility model patent application number 202321739347.9 discloses a disposable stool cup for convenient sampling. It involves pressing a sampling spoon and clamp with two fingers to collect a suitable amount of stool sample, placing it into the cup, then pressing the top of the clamp to detach it from the cup lid. The clamp is then discarded into a trash can, and the cup lid is replaced to complete the sampling. However, this patent has the following drawbacks in the sampling process:
[0003] 1. For example Figure 1 As shown, since the clamp is set vertically in the length direction, when the bottom of the clamp cannot fit with the bottom of the sampling spoon, that is, when the clamp cannot cover the sampling spoon, the sample will flow out from the sampling spoon when the stool sample is loose.
[0004] 2. When sampling, press the sampling spoon and clamp with two fingers. The sampling spoon and clamp will bend and deform. After sampling, release the fingers and the sampling spoon and clamp will return to their original shape under the action of elasticity. Under the action of this elasticity, the sample on the sampling spoon and clamp will be thrown outward, thus causing pollution to the surrounding environment. Utility Model Content
[0005] In summary, in order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a fecal sampler.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A stool sampler includes a cup lid, a cup body, a sampling spoon, and a clamp. The cup lid is detachably installed at the top opening of the cup body. The top of the sampling spoon is fixed at the middle position of the bottom of the cup lid. The bottom of the sampling spoon extends vertically downwards for a predetermined distance and is connected to a spoon body for scooping samples. A flange is detachably provided on one side of the cup lid. The top of the clamp is rotatably installed on the flange. The lower end of the clamp extends vertically downwards for a predetermined distance on the outside of the cup body and is fixed with a clamping block. The clamping block is obliquely downwards towards the outside of the cup body from top to bottom, so that after the clamp rotates towards the sampling spoon, the clamping block can cover the opening of the spoon body.
[0007] The beneficial effects of this utility model are: during sampling, the clamp can cover the opening of the spoon body to prevent loose stool from flowing out of the spoon body; the clamp can be rotated to clamp the sample with the sampling spoon, and the sampling spoon and clamp will not bend or deform, preventing the sample on the sampling spoon and clamp from being thrown out during the process of restoring the original shape.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, one side of the cup lid is provided with an upward-facing slot, and the flange is provided with a locking strip that matches the slot; the locking strip is inserted downward into the slot to detachably mount the flange onto the cup lid.
[0010] The beneficial effect of adopting the above-mentioned further solution is that it enables the flange and the cup lid to be detachably installed so that the clamp can be discarded in a designated place after sampling.
[0011] Furthermore, the top of the clamping plate is rotatably mounted on the flange via a pivot, and the flange has a notch for the clamping plate to rotate.
[0012] The beneficial effect of adopting the above-mentioned further solution is that it enables the clamp to be rotatably mounted on the flange, preventing the sampling spoon and clamp from bending and deforming during the sampling process.
[0013] Furthermore, the cup lid is threaded onto the opening at the top of the cup body.
[0014] The beneficial effect of adopting the above-mentioned further solution is that it enables the cup lid and the cup body to be detachably installed. Attached Figure Description

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0022] like Figure 2As shown, a stool sampler includes a lid 1, a cup body 2, a sampling spoon 3, and a clamping plate 4. The lid 1 is detachably mounted on the top opening of the cup body 2. The top of the sampling spoon 3 is fixed to the middle of the bottom of the lid 1, and the bottom of the sampling spoon 3 extends vertically downwards for a predetermined distance before being connected to a spoon body for scooping samples. A flange 5 is detachably provided on one side of the lid 1, and the top of the clamping plate 4 is rotatably mounted on the flange 5. A clamping block 6 is fixed to the lower end of the clamping plate 4 extending vertically downwards for a predetermined distance on the outside of the cup body 2. The clamping block 6 is obliquely downwards towards the outside of the cup body 2 from top to bottom, so that after the clamping plate 4 rotates towards the sampling spoon 3, the clamping block 6 can cover the opening of the spoon body.
[0023] Preferably, the cup lid 1 has an upward-facing slot on one side, and the flange 5 has a retaining strip 7 that matches the slot. The retaining strip 7 is inserted downward into the slot to detachably mount the flange 5 onto the cup lid 1.
[0024] like Figure 3 As shown, the top of the clamping plate 4 is rotatably mounted on the flange 5 via a pivot 8, and the flange 5 has a notch 9 for the clamping plate 4 to rotate.
[0025] Preferably, the cup lid 1 is threaded onto the top opening of the cup body 2.
[0026] During sampling, first remove the lid 1 from the cup body 2. Then place the bottom of the sampling spoon 3 at the sample location. Press the clamp 4 and the sampling spoon 3 together with two fingers. Since the clamp 4 is rotatably mounted on the flange 5, after pressing the clamp 4 and the sampling spoon 3 together, the clamp 4 rotates towards the sampling spoon 3. Finally, the clamp block 6 of the clamp 4 will close onto the opening of the sampling spoon 3, and the sample will be collected into the body of the sampling spoon 3. Then, place the clamp 4 and the sampling spoon 3 into the cup body 2, and then rotate the clamp 4 in the opposite direction to open the sampling spoon 3, and place the obtained sample into the cup body 2. Figure 4 As shown, because the clamp 6 covers the opening of the sampling spoon 3, even if the stool is very loose, it will not flow out of the sampling spoon 3, thus enabling the sampling of very loose stool. Furthermore, when the clamp 4 rotates closer to the sampling spoon 3, the sampling spoon 3 and clamp 4 will not bend or deform, preventing the sample from being thrown out during the restoration process. After the sample is placed in the cup body 2, lift the flange 5 from the cup lid 1 to disengage the locking strip 7 from the slot on the cup lid 1, then remove the flange 5 from the cup lid 1. Finally, discard the flange 5 along with the clamp 4 in a designated place, and then tighten the cup lid 1 back onto the cup body 2.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
