Matching structure of liquid collector and test tube assembly and liquid collector

Abstract

The invention relates to a urine collection device, in particular to a stackable liquid collector and a matching structure of the liquid collector and a test tube assembly. The invention discloses a matching structure of a liquid collector and a test tube assembly. The lower part of the liquid collector is matched with an opening part of the test tube assembly; a liquid gathering part with an upward opening is defined by an annular side wall A of the liquid collector and a bottom sealing plate, and a liquid guide hole is formed in the bottom sealing plate; a third side wall located below the bottom sealing plate and located on the periphery of the liquid guide hole is inserted into the opening part of the test tube assembly to be matched with the test tube assembly; the second side wall islocated on the inner side of the third side wall, and the second side wall, the third side wall and the bottom sealing plate jointly form a groove. Another subject of the invention is a liquid collector. The liquid collector has the advantages of stackable property, smooth liquid guide, low cost, high production efficiency and high rate of finished products.

Description

technical field [0001] The invention relates to a urine collecting device, in particular to a stackable liquid collecting device and a matching structure of the liquid collecting device and a test tube assembly. Background technique [0002] In the liquid collector in the prior art, the exhaust channel surrounded by the exhaust side wall is located in the liquid guide channel enclosed by the side wall of the liquid collecting liquid. The liquid guide channel and the exhaust channel respectively pass through the bottom cover plate and form a liquid guide hole and an exhaust hole on the back cover plate, and the liquid guide channel and the exhaust channel located below the back cover plate have a common side wall. But this structure has several problems: [0003] 1. The exhaust channel enclosed by the annular exhaust side wall is located in the liquid guide channel formed by the annular liquid guide side wall that gathers the liquid. In the process of collecting liquid, sin...

Problems solved by technology

[0005] Two, if figure 1 , figure 2 As shown, when the lower part 1 of the liquid collector is matched with the opening of the test tube assembly (the lower part 1 of the liquid collector is inserted and fixed in the opening of the test tube assembly), and the diameter of the test tube is a fixed value, so that the liquid collected under the bottom cover plate The maximum outer diameter D of the lower part of the collector can only be regulated within a relatively limited size. Since the liquid guide channel 19 and the exhaust channel 59 below the bottom cover plate have a common side wall, the wall thickness of the lower part 1 of the liquid collector is uneven.

Due to the uneven wall thickness of the lower part 1 of the liquid collector, the shrinkage rate of each part is different, and a pit 9 is formed in the lower part 1 of the liquid collector, so that the yield and efficiency of production cannot be effectively guaranteed.

[0006] 3. Urine collection devices in the prior art cannot be stacked, resulting in a large space occupation, which takes up a large space when stacked in warehouses, during transportation, and when placed in hospitals or laboratories

Especially in the transportation process, the quantity that can be transported in a limited space is small, which increases the cost of transportation, that is, also increases the cost of the product
