Problems solved by technology

[0004] However, since the water sealing ring is set on the plunger sleeve, and the plunger sleeve moves up and down under the action of the rotating base, the water sealing ring also moves up and down. During the up and down movement, the water sealing ring will It will rub against the wall of the test cup, and may fall off due to excessive friction, destroying the sealing of the control device at the bottom of the cup, causing liquid leakage, polluting the environment, and affecting the normal testing

Embodiment 1

[0043] A liquid detection device, comprising: a cup body, a detection part and a control device.

[0044] The cup is provided with a spacer, and the spacer divides the inner space of the cup into a sample loading cavity and a control cavity. The spacer is provided with a sample inlet and a sample loading port, and the control cavity is located on the side wall of the cup body Open your mouth.

[0045] The detection part is arranged on the side of the cup body, and a detection chamber connected with the sample loading port is arranged inside it for placing detection test strips.

[0046] The control device is placed in the control chamber, including a sample injection sealing ring, a sample loading sealing ring, and a rotary rod. Both the sample injection sealing ring and the sample loading sealing ring are set and fixed on the rotary rod, and are closely matched with the inner wall of the spacer, and an accommodation cavity is formed between the inner wall of the spacer, the sa...

Embodiment 2

[0051] A liquid detection device such as figure 1 As shown, it includes: a cup body 1 , a detection part 2 , a control device 3 and a base 4 .

[0052] The cup body 1 is provided with a spacer 11, such as figure 2 As shown, the spacer 11 divides the inner space of the cup body into a sample loading chamber and a control chamber, and the spacer 11 is provided with a sample inlet 111 and a sample loading port 112, and the control chamber is opened on the side wall of the cup body. Such as image 3 shown.

[0053] The detection part 2 is arranged on the side of the cup body, and a detection chamber communicating with the sample loading port is arranged inside it for placing the detection test strip 6 .

Abstract

The invention discloses a liquid detection device and a liquid detection method, belonging to the technical field of liquid detection. The detection device comprises a cup body, a detection part and a control device, wherein a spacer bush is arranged in the cup body; an injection opening and a loading opening are formed in the spacer bush; a detection cavity communicated with the loading opening is formed in the detection part; the control device is arranged in the control cavity and comprises a sample injection sealing ring, a loading sealing ring and a rotating rod; the sample injection sealing ring and the loading sealing ring are fixedly arranged on the rotating rod in a sleeving manner and are tightly matched with the inner wall of the spacer bush so as to form a containing cavity; a sample injection notch and a loading notch are respectively formed in the sample injection sealing ring and the loading sealing ring; the rotating rod can rotate along the axial direction and has a sample injection state position and a loading state position. According to the detection device and the detection method, the notches through which to-be-detected liquid circulates are formed in the sealing rings, so that the opening / closing states of the injection opening and the loading opening are controlled by virtue of rotation of the sealing rings, the sealing property of the detection device is improved, and the reliability of the detection method is improved.

Description

technical field [0001] The invention relates to the technical field of liquid detection, in particular to a liquid detection device and a liquid detection method. Background technique [0002] In the prior art, for the detection of liquid samples such as urine, the liquid detection cup is generally used to hold the liquid, and the liquid is contacted with the test card on the wall of the detection cup to load the detection test strip, thereby realizing the detection of the liquid. [0003] In order to control the contact between the liquid sample and the test strip, in the conventional technology, a liquid detection cup with a control device is often used. In and out control of the test sample, when the rotating base rotates, the threaded hook on the rotating base will slide along the thread groove on the plunger sleeve, and drive the plunger sleeve to move up and down. The plunger sleeve is provided with a sampling notch and a sample loading notch, and a water sealing ring...
