Problems solved by technology

However, a new problem has been discovered in the clinical inspection work recently, that is, some parasitic protozoa cannot be detected by conventional centrifugal sedimentation methods, and they are suspended in the liquid, so that they cannot be diagnosed and treated

Embodiment 1

[0035] figure 1 It is a schematic diagram of the appearance structure of the stool sampling and parasite concentrator in Embodiment 1 of the present invention;

[0036] Such as figure 1 As shown, the structure of feces sampling and parasite concentrator 100 includes a first sample storage container 11 and a second sample storage container 12 and image 3 The annular plastic ring 241 in the center, the centrifuge end of the second sample storage container 12 is outwardly convex conical, to facilitate the subsequent centrifugation of samples, meanwhile, the ports of the first sample storage container 11 and the second sample storage container 12 have internal thread.

[0037] figure 2 It is a schematic diagram of the composition and structure of the stool sampling and parasite concentrator in Embodiment 1 of the present invention.

[0038] Such as figure 2 As shown, in addition to the first sample storage container 11 and the second sample storage container 12, the stool ...

Embodiment 2

[0055] In the second embodiment, the same structures as those in the first embodiment are given the same symbols, and the same descriptions are omitted.

[0056] Figure 5 It is a schematic structural diagram of the original sample sampling device in Example 2.

[0057] Such as Figure 5 As shown, the original sample sampling device 200 includes: a third sample storage container 13 and a sampling device 14, the sampling device 14 includes a top cover 141 in addition to the spoon head 21 and the connecting rod 22 in Embodiment 1, and one end of the connecting rod 22 It is connected with the spoon head 21 , and the other end is connected with the top cover 141 , and the port of the third sample storage container 13 is provided with external threads, wherein the external threads can be matched with the top cover 141 for use.

[0058] During use, the top cover 141 is unscrewed from the third sample storage container 13, and after a certain volume of original feces sample is take...

Abstract

The invention provides a feces sampling, filtering, and parasite concentrator, including: a sample storage container; and a sampling and filtering device, including a sampling spoon, a barrel-shaped filter screen and a mounting handle, the sampling spoon includes a spoon head and a connecting rod, The spoon head is connected with one end of the filter screen through the connecting rod, and the other end of the filter screen is airtightly connected with the installation handle, and the installation handle and the sample storage container are detachably connected. This structure makes the sampling and parasite concentrator of the present invention have the advantages of simple structure, good sealing performance, and convenient sample retention and removal; because the filter screen is barrel-shaped, the filtration area can be increased, which can further improve the filtration efficiency and speed up the sampling process. The follow-up processing speed is increased, and the large-diameter filter holes are added to facilitate the detection of protozoa with large diameters and suspensions that are difficult to centrifuge.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a feces sampling and parasite concentrator. Background technique [0002] Parasites in the human body will have varying degrees of impact on the health of the human body, parasites in different parts of the body, parasites or parasite eggs will be taken out of the body through the cavity that communicates with the body surface at the corresponding parasite site, and parasites in the digestive system Most of the worms are excreted from the human stool, so the detection of stool samples has become an indispensable content in the clinical diagnosis and treatment of intestinal infectious diseases. Different individuals have different dietary structures and eating and chewing habits, resulting in differences in the types and sizes of impurities in the feces. Large impurities can easily interfere with the microscopic examination of parasites, leading to clinical misdiagnosis or missed di...
