It can accurately reflect the patient's current physical condition, disease condition and other information based on the test results, which is conducive to the doctor's more accurate judgment of the patient's physical condition and disease condition, thereby facilitating the doctor to provide accurate treatment.

[0003] At present, medical staff often need to use corresponding feces samplers when taking feces samples from patients. Although the existing feces samplers can perform basic feces sampling in actual use, the sampling heads are fixed in design and cannot be adjusted in length during the sampling operation, which makes the medical staff's hands close to the feces, causing psychological discomfort to the medical staff. Therefore, they need to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a feces sampler which has the advantage of adjustable sampling distance.

[0005] To achieve the above object, the utility model provides the following technical solution: a feces sampler, comprising:

[0006] A storage tube, wherein a sealing cover is sleeved on the internal thread of the top end of the storage tube;

[0007] A top cover, the top cover is fixedly mounted on the top of the sealing cover, arc-shaped plates are fixedly mounted on both sides of the top of the top cover, the number of the arc-shaped plates is two, the tops of the two opposite surfaces of the arc-shaped plates are each provided with a first groove, and the bottoms of the two opposite surfaces of the arc-shaped plates are each provided with a second groove;

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 4 As shown, the utility model provides a feces sampler, comprising:

[0027] A storage tube 1, a sealing cap 2 is sleeved on the internal thread of the top end of the storage tube 1;

[0028] A top cover 3, the top cover 3 is fixedly mounted on the top of the sealing cover 2, and arc plates 4 are fixedly mounted on both sides of the top of the top cover 3. There are two arc plates 4, and the tops of the opposite surfaces of the two arc plates 4 are each provided with a first groove 7, and the bottoms of the opposite surfaces of the two arc plates 4 are each provided with a second groove 8;

[0029] A clamping mechanism, which is arranged between two arc-shaped plates 4;

[0030] Among them, the clamping mechanism includes a sampling spoon handle 5, the outer surface of the sampling spoon handle 5 is movably connected to the inside of the sealing cover 2 and the top cover 3, the bottom end of the sampling spoon handle 5 is located inside the storage tube 1, and the top of the sampling spoon handle 5 is fixedly installed with a cylindrical head 6 located between the arc plates 4, and both sides of the inside of the cylindrical head 6 are movably connected with movable blocks 9. There are two movable blocks 9, and the opposite backs of the two movable blocks 9 are fixedly installed with a clamping rod 10, the other end of the clamping rod 10 penetrates the cylindrical head 6 and extends to the outside of the cylindrical head 6, and the other end of the clamping rod 10 is located inside the first groove 7, and a spring 11 is fixedly connected between the two movable blocks 9.

[0031] When the operator presses the cylindrical head 6 downward, the outer surface of the first groove 7 will squeeze and push the clamping rod 10, so that the clamping rod 10 can drive the movable block 9 to move inside the cylindrical head 6 and squeeze the spring 11, and then the cylindrical head 6 can drive the sampling spoon handle 5 to move downward. When the clamping rod 10 reaches the position of the second groove 8, due to the elastic recovery effect of the spring 11, the clamping rod 10 will be stuck into the second groove 8, thereby achieving the effect of fixing the positions of the sampling spoon handle 5 and the cylindrical head 6, thereby increasing the length of the sampling spoon handle 5 under the sealing cover 2, so that the sampling spoon handle 5 can ensure that the operator's hands are away from feces when sampling feces.

[0032] The bottom of the sampling spoon handle 5 is fixedly connected to a sampling spoon head 13 located inside the storage tube 1 , and the outer surface of the sampling spoon head 13 is smooth.

[0033] Due to the design of the sampling spoon head 13, samples in feces can be dug out.

[0034] The outer surface of the top cover 3 is fixedly sleeved with a pipe sleeve 12 , and the inner surface of the pipe sleeve 12 is movably sleeved with the outer surface of the storage tube 1 .

[0035] The design of the sealing cover 2 can provide a preliminary sealing effect on the interior of the storage tube 1, and the design of the tube sleeve 12 can strengthen the sealing effect on the interior of the storage tube 1, thereby effectively preventing feces and even odors from escaping.

[0036] The movable block 9 has a rectangular shape, and the outer surface of the movable block 9 and the inner surface of the cylindrical head 6 are both smooth.

[0037] Such a design enables the movable block 9 to move more smoothly inside the cylindrical head 6 .

[0038] The interiors of the first groove 7 and the second groove 8 are both arc-shaped, and the first groove 7 and the second groove 8 have the same size.

[0039] Such a design enables the outer end of the clamping rod 10 to be well clamped inside the first groove 7 and the second groove 8 .

[0040] There are two clamping rods 10 , the two clamping rods 10 have the same size, and the two clamping rods 10 are symmetrical with respect to the center of the cylindrical head 6 .

[0041] The design of the two clamping rods 10 makes the overall fixation of the sampling spoon handle 5 and the cylindrical head 6 more firm and stable.

[0042] The spring 11 is located between the middle parts of the two movable blocks 9, and the spring 11 is in a compressed state.

[0043] Since the spring 11 is in a compressed state, an elastic force is applied to the two movable blocks 9 , so that the two clamping rods 10 can be firmly clamped inside the first groove 7 .

[0044] There are circular holes in the sealing cover 2 and the top cover 3 . The diameter of the circular hole is the same as the diameter of the sampling spoon handle 5 . The inner surface of the circular hole and the outer surface of the sampling spoon handle 5 are both smooth.

[0045] Due to the smooth design of the round hole, the sampling spoon handle 5 can move up and down more smoothly.

[0046] The working principle and use process of this utility model:

[0047] When it is necessary to sample the patient's feces, the medical staff rotates the storage tube 1 and the sealing cover 2 to open, separate the device, and then presses the top of the cylindrical head 6. Since the inside of the first groove 7 squeezes the outer surface of the card rod 10, the card rod 10 squeezes the spring 11 inward through the movable block 9. At this time, the spring 11 is in a compressed state, and then pushes the cylindrical head 6 downward to drive the two ends of the card rod 10 to the position of the second groove 8. At this time, due to the elastic recovery effect of the spring 11, the card rod 10 is pushed through the movable block 9, so that the two ends of the card rod 10 are clamped in the inside of the second groove 8, thereby changing the length of the sampling spoon handle 5 under the sealing cover 2, ensuring that the sampling spoon head 13 can be kept away from the hands of the medical staff.

[0048] After the sampling spoon head 13 has completed sampling the patient's feces, the sampling spoon head 13 together with the patient's feces sample can be placed into the storage tube 1, and then the sealing cover 2 is rotated to initially seal the interior of the storage tube 1, and the tube sleeve 12 is sleeved on the top of the outer surface of the storage tube 1, so that the interior of the storage tube 1 can be secondary sealed, effectively preventing the odor of feces from escaping.
