Abstract

The present invention provides a body fluid inspection device comprising a holding element and an inspecting element, the inspecting element is located within the holding element. The top of the inspecting element is higher than the top of the holding element. When inspecting liquids such as saliva, even if an inspection subject does not use a sample collector, this arrangement allows the direct collection of the saliva from a mouth cavity into the holding element without the inspecting element being contaminated thus affecting the validity of an inspection. In addition, since the holding element is a polyhedron, placing the inspection element directly on a photocopier for photocopying is possible, and recording an inspection result on each side of the polyhedron is convenient.

Referring to Figures 1-8, the body fluid collection device of the present invention includes a sample collection device 300, a detection component 200, and a receiving component 100. The sample collector 300 includes a sampling head 301, a connecting rod 302, and a handle 303. The handle of the present embodiment is In the form of a top cover, the top cover operatively incorporates the detecting member 200, and the top cover is coupled to the sampling head 301 via a connecting rod 302. The detecting member 200 includes a top portion 201 at the top of the detecting member and higher than the receiving portion, a groove 202 on the outer wall of the detecting member 200, a test strip positioning groove 203, a seal ring 204, a post 205, and a shoulder 206. Two pairs of shoulders 206 are respectively disposed at upper and lower portions of each test strip positioning groove, and a pair of shoulders are respectively disposed at upper and lower portions of the detection area of the test strip in the test strip positioning groove, and the purpose of setting the shoulder is to The test strip is better fixed in the positioning groove. The test strip positioning grooves 203 are provided at intervals on the outer wall of the detecting member 200, and a test strip is fixed inside. The sealing ring is disposed above the detecting member test strip positioning groove, and is located at a portion where the detecting member 200 and the receiving member 100 are combined, in order to prevent the collected body fluid from flowing out between the detecting member and the receiving member.

The accommodating member 100 includes a projection 101, a boss 102, and a liquid flow path 103. The projection 101 cooperates with the recess 202 to fix the detecting member 200 in the accommodating member 100. The boss 102 is located at the bottom of the inner cavity of the accommodating member 100, and the boss 102 and the bottom of the inner cavity of the accommodating member 100 form an area for fixing and squeezing the sampling head 301, and between the inner wall of the accommodating member 100 and the boss 102, and optionally The liquid flow path 103 is provided between two adjacent bosses 102.
