Embodiment 1

[0072] Such as Figure 1-7 As shown, it is a sampling device of this embodiment, including a first container 100, a first container 100 is provided with a first housing chamber 101 and a sampling tank 102, and the first housing chamber 101 communicates with the sampling tank 102; the sampling device also Including a sampling assembly 300, the sampling assembly 300 is used to be arranged in the first container 100; when in the sampling position, the sampling assembly 300 prevents the first accommodating chamber 101 from communicating with the sampling tank 102, and makes the sampling tank 102 communicate with the outside of the first container 100 connected.

[0073] The sampling positions include a first position, the first position is located on the plane where the upper opening of the sampling tank 102 is located, and the sampling assembly 300 first moves to the first position so that the first receiving cavity 101 is not connected to the sampling tank 102 .

[0074] The wo...

Embodiment 2

[0131] Such as Figure 12 As shown, the structure of the sampling device of this embodiment is basically the same as that of Embodiment 1, the main difference is that: the guide 210 is integrally formed with the upper cover 200, and the lower end of the guide 210 has a certain distance from the end face of the upper opening of the sampling tank 102. , forming the communication passage 213 between the first storage chamber 101 and the sampling tank 102, at this time, there is no need to set a gap 212 on the guide 210, and the communication passage 213 prevents the guide 210 from preventing the biological sample in the first storage chamber 101 from entering the sampling chamber. The tank 102 and the communication path 213 will also make the excess biological samples outside the sampling tank 102 separated from the sampling tank 102 when the sampling assembly 300 is in the sampling position.

Embodiment 3

[0133] Such as Figure 13As shown, the structure of the sampling device of this embodiment is basically the same as that of Embodiment 1, the main difference is that: in this embodiment, the guide 210 is arranged on the first container 100 and integrally formed with the first container 100 . In this embodiment, the opening at the lower end of the guide channel 211 of the guide member 210 corresponds to the opening of the sampling tank 102, and the lower end of the guide channel 211 is provided with a gap 212 communicating with the first receiving cavity 101 and the sampling tank 102, and the gap 212 is used for The biological sample in the first storage chamber 101 enters the sampling tank 102 , which is also used to make the biological sample outside the sampling tank 102 and located in the guide channel 211 flow back into the first storage chamber 101 .

[0134] The upper opening of the guide passage 211 communicates with the second through hole 201 of the upper cover 200 . ...

Abstract

The invention discloses a sampling device and a sample processing device.The sampling device comprises a first container, wherein the first container is internally provided with a first containing cavity and a sampling groove, and the first containing cavity is communicated with the sampling groove; the sampling device further comprises a sampling assembly; the sampling assembly is arranged in the first container; at the sampling position, the sampling assembly prevents the first accommodating cavity from being communicated with the sampling groove and enables the sampling groove to be communicated with the outside of the first container. According to the sampling device, the first containing cavity and the sampling groove are formed in the first container, and a biological sample enters the sampling groove through the first containing cavity; due to the fact that the sampling groove has the fixed volume, the biological sample with the fixed volume can be obtained by taking out the biological sample in the sampling groove through the sampling assembly; therefore, the sampling personnel can operate without observation, the sampling volume error is avoided, and the sampling efficiency of the sampling personnel is effectively improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a sampling device and a sample processing device. Background technique [0002] In clinical practice, when it is necessary to detect biological samples (such as sputum), it is generally performed by manually aspirating a variable volume of sputum into the sampling tube, and adding a corresponding volume of processing fluid (digestive fluid) to each sputum. deal with. However, when the number of samples to be detected is large, it is difficult to add different volumes of processing liquid according to the volume of each sample. Generally, a fixed volume of processing liquid is used, which requires the volume of the sample in each sampling tube unanimous. For example, if the optimal volume ratio of sputum and digestive fluid is 1:2, and the volume of digestive fluid in each sampling tube is fixed at 2mL, the sample volume of sputum in each sampling tube should be 1mL. Due to the...
