Gastrointestinal flora sampling apparatus

Abstract

The invention discloses a gastrointestinal flora sampling apparatus which comprises a sampling ball and a shell. The sampling ball is arranged in the shell, the opening in the surface of the samplingball sinks inwards to form a sampling groove, and a sampling port is arranged in the shell; the inner wall of the sampling groove is coated with edible gum; the gastrointestinal flora sampling apparatus further comprises a spring capable of making the shell move relative to the sampling ball. The gastrointestinal sampling apparatus is convenient in use and suitable for timing and locating gastrointestinal tract area for sampling with good compliance and causes little pain to users.

Description

Technical field

[0001] The invention belongs to the technical field of medical appliances, and in particular relates to a sampling device for gastrointestinal flora.

Background technique

[0002] Gastrointestinal disease is a common disease, therefore, gastrointestinal sampling is of great significance for the diagnosis and treatment of gastrointestinal diseases. The commonly used method is gastroscopy or extracting a certain amount of gastric juice in the process of traditional interpolation gastroscopy. However, the above method is not easy to operate, and the patient's compliance is poor.

Content of invention

[0003] In order to solve the above problems, the present invention provides a gastrointestinal flora sampling device that is easy to operate, can be sampled regularly and has good compliance.

[0004] The present invention is a gastrointestinal flora sampling device realized through the following technical scheme, comprising a sampling ball and a housing,...

Examples

Embodiment 1

[0021] Figure 1 and figure 2 As shown, a gastrointestinal flora sampling device includes a sampling ball 1 and a housing 2, the sampling ball 1 is arranged inside the housing 2, and the surface of the sampling ball 1 is provided with an opening 11 and is recessed inward Form a sampling tank 12, the housing 2 is provided with a sampling port 21; the inner wall of the sampling tank 12 is coated with edible glue; 1 Relatively moving mainspring.

[0022] Further, one side of the sampling tank 12 inner wall is provided with soluble calcium salt, and the other side is provided with citrate and / or oxalate.

[0023] Further, the sampling grooves 12 are arranged in groups, and the planes of the sampling grooves 12 between different groups are parallel to each other; the sampling grooves 12 in the same group are arranged at intervals; the housing is provided with at least one sampling groove 12 corresponding to each group The sampling port 21, the direction of relative movement betwe...

Embodiment 2

[0032] Such as image 3 Shown, on the basis of embodiment one, sampling ball 1 is provided with 1 group of sampling ports and 2 groups of springs for sampling, by increasing the number of springs and / or adjusting the size and The degree of density can serve the purpose of adjusting the relative movement speed between the sampling ball 1 and the housing 2 . For example, if image 3 The two springs in the middle can drive the housing 2 to rotate in the same direction, which can speed up the relative movement between the housing 2 and the sampling ball 1, and shorten the sampling time; if image 3 The 2 springs in the middle can drive the housing 2 to rotate in opposite directions, so that the relative motion between the housing 2 and the sampling ball 1 can be slowed down to prolong the sampling time. In addition, a corresponding adjustment function can also be achieved by selecting scroll springs with different elastic forces.

Embodiment 3

[0034] As shown in Figure 4, on the basis of the first embodiment, two or more springs can share one spring shaft 15, so as to set the scroll springs 14 in multiple barrels 13 at the same time.
