As shown in fig. 1 and 2, a totally enclosed test urine cup for facilitating control of test sample amount comprises an outer cylinder 1, an upper cover 2, a funnel-shaped inner cylinder 3 and a test paper detection structure 4. The top of the outer cylinder 1 is opened, and the bottom is closed. The funnel-shaped inner cylinder 3 is installed in the outer cylinder 1. The large diameter opening of the funnel-shaped inner cylinder 3 is positioned at the opening of the outer cylinder 1. The large diameter opening of the funnel-shaped inner cylinder 3 is integrally formed with an annular flange 5; the outer edge of the annular flange 5 is in sealing and fixed connection with the opening of the outer cylinder 1. The large diameter opening of the funnel-shaped inner cylinder 3 is provided with an external thread 6. The external thread is located on the side of the annular flange 5 remote from the inner cavity of the outer barrel 1. The upper cover 2 is provided with internal threads; the internal thread on the upper cover 2 is in threaded connection with the external thread on the funnel-shaped inner cylinder 3.
The large diameter opening of the funnel-shaped inner cylinder 3 is a round urine inlet 1-1; the small diameter opening of the funnel-shaped inner cylinder 3 extends to the bottom of the inner cavity of the outer cylinder 1; the inner side wall of the outer cylinder 1 is provided with annular bulge indicating scale marks 1-2; indicating that the graduation marks 1-2 are aligned with the outer end edge of the buffer tube.
The funnel-shaped inner cylinder 3 comprises an integrally formed funnel body and a buffer tube. The top of the buffer tube is connected with the output port (namely the small diameter port) of the funnel main body. The inner diameter of the buffer tube is equal to the diameter of the output port (namely the small diameter port) of the funnel body. The bottom end of the buffer tube is a small diameter port of the funnel-shaped inner cylinder 3. The axis of the buffer tube coincides with the central axis of the inner cavity of the outer cylinder 1.
As shown in fig. 3, 4 and 5, the test paper detecting structure 4 is provided on the inner side wall of the outer tub 1. The test paper detecting structure 4 includes a reagent strip mounting member 4-1 and a fixing member 4-2. The three fixing pieces 4-2 are all fixed on the inner side wall of the outer cylinder 1. The three fixing pieces 4-2 are sequentially arranged at intervals along the circumferential direction of the axis of the outer cylinder.
The reagent strip mounting member 4-1 is circular arc-shaped, and its outward convex side surface shape corresponds to the shape of the inner side wall of the outer cylinder 1. Of the three fixing pieces 4-2, two fixing pieces 4-2 at both ends and the inner side wall of the outer cylinder 1 form an installation clamping groove. Two ends of the reagent strip mounting piece 4-1 are respectively clamped in the two mounting clamping grooves. Of the three fixing members 4-2, the middle fixing member 4-2 abuts against the outer convex side of the reagent strip mounting member 4-1. The distance between the mounting clamping groove and the annular flange 5 is 1 cm-2 cm.
A reagent strip mounting groove is formed in the reagent strip mounting member 4-1. One end of the reagent strip mounting groove is opened, and the other end is closed. The open end of the reagent strip mounting groove faces to the opening of the outer barrel 1. The open end of the reagent strip mounting groove faces to the bottom of the inner cavity of the outer barrel 1. The open end of the reagent strip mounting groove is spaced from the annular flange 5. One or more reagent strips are arranged in the reagent strip mounting groove; in the case where the outer cylinder 1 is in the normal position, the result reading area of the reagent strip is located below the sample loading area, i.e., the sample loading area of the reagent strip is located at the open end of the reagent strip mounting member 4-1.
Dividing the inner cavity of the outer cylinder 1 into a reaction chamber between the inner side wall of the outer cylinder 1 and the outer side surface of the funnel-shaped inner cylinder 3; an excess storage chamber inside the funnel-shaped inner cylinder 3.
When the totally enclosed test urine cup is inverted, the sample liquid is transferred from the region of the reaction chamber away from the urine inlet 1-1 (i.e., the bottom when being placed upright) to the region near the urine inlet 1-1 (i.e., the top when being placed upright); a sample liquid infiltrates the sample adding area of the reagent strip, and starts a chromatographic running plate; after the running board is completed, the result reading area of the reagent strip reads whether the urine sample contains target substances or not.
The present embodiment provides an optional preferred technical solution: the urine cup outer cylinder 1 is made of elastic material and can be extruded and deformed.
The working principle of the utility model is as follows:
firstly, the outer cylinder 1 is vertically placed and the urine inlet 1-1 is upwards arranged; opening the upper cover 2; adding a urine sample into the funnel-shaped inner cylinder 3 from the urine inlet 1-1; the upper cover 2 is screwed. The inspector can assist the urine sample of the funnel-shaped inner cylinder 3 to flow into the bottom of the outer cylinder 1 more quickly by pressing the outer cylinder 1 of the urine cup with force. When the liquid level of the urine sample reaches the scale mark, the small diameter opening at the bottom of the funnel-shaped inner cylinder 3 is penetrated by the urine sample. At this time, the reaction chamber in the outer cylinder 1 forms a closed space; the urine sample in the funnel-shaped inner barrel 3 cannot continuously enter the reaction chamber under the action of the internal pressure of the reaction chamber, so that excessive urine sample is prevented from entering the reaction chamber.
When detection is needed, the outer cylinder 1 is quickly turned over by 180 degrees, so that the upright totally-enclosed test urine cup is turned upside down; in the process of totally-enclosed test urine cup overturning, only a small amount of urine sample in the excessive storage chamber (namely the inside of the funnel-shaped inner barrel 3) enters the reaction chamber in the outer barrel 1, and most of urine sample in the excessive storage chamber still remains in the excessive storage chamber; therefore, accurate quantitative detection of the urine sample is realized in an extremely simple mode.
Finally, after the urine sample in the reaction chamber turns over in the outer barrel 1, the urine sample can infiltrate the sample adding area of the reagent strip. After a few minutes, the detection personnel can judge the detection result through the color change of the test strip.
Example 2
A totally enclosed test urine cup which facilitates control of test sample volume, the difference between this embodiment and embodiment 1 is that: a conduit 7 is provided near the large diameter opening of the funnel-shaped inner cylinder 3.
In this embodiment, as shown in fig. 6, a conduit 7 is connected between the large diameter opening of the funnel-shaped inner cylinder 3 and the annular flange 5. The inner diameter of the conduit 7 is smaller than the inner diameter of the buffer tube of the funnel-shaped inner cylinder 3; one end of the conduit 7 is communicated with the urine inlet 1-1, the other end of the conduit vertically extends to the bottom of the inner cavity of the outer cylinder 1, and the edge of the conduit is aligned with the edges of the indication scale marks 1-2 and the small-diameter opening of the funnel-shaped inner cylinder 3. The conduit 7 may temporarily communicate the urine cup overstock chamber with the urine cup internal reaction chamber. Urine sample is added into the funnel-shaped inner barrel 3 from the urine inlet 1-1, and because the air in the reaction chamber in the outer barrel 1 can be discharged through the guide pipe 7, the urine sample can quickly flow into the bottom of the outer barrel 1 without the need of a detection personnel to squeeze the cup body. When the liquid level of the urine sample reaches the scale mark, the small diameter opening at the bottom of the funnel-shaped inner cylinder 3 and the bottom of the conduit 7 are all soaked by the urine sample. At this time, the reaction chamber in the outer cylinder 1 forms a closed space; the urine sample in the funnel-shaped inner barrel 3 cannot continuously enter the reaction chamber under the action of the internal pressure of the reaction chamber, so that excessive urine sample is prevented from entering the reaction chamber.
Other structures of this embodiment are the same as those of embodiment 1.
Example 3
A totally enclosed test urine cup which facilitates control of test sample volume, the difference between this embodiment and embodiment 1 is that: the buffer tube shape of the funnel-shaped inner cylinder 3 is set differently.
In this embodiment, as shown in fig. 7, a hole 8 is formed in a region of the buffer tube of the funnel-shaped inner cylinder 3 near the bottom of the inner cavity of the outer cylinder 1; the diameter of the hole 8 is smaller than the inner diameter of the buffer tube of the funnel-shaped inner cylinder 3; the upper edge of the hole 8 is aligned with the indicating graduation marks 1-2; the small diameter opening of the funnel-shaped inner cylinder 3 is positioned in the outer cylinder 1 and extends to the bottom of the inner cavity of the outer cylinder 1; the small diameter opening of the funnel-shaped inner cylinder 3 is an oblique incision; facilitating the flow of urine sample into the bottom of the outer cartridge 1. When a urine sample is added into the funnel-shaped inner cylinder 3 from the urine inlet 1-1, the air in the reaction chamber in the outer cylinder 1 can be discharged through the hole 8, so that a detection person does not need to squeeze the cup body, and the urine sample can quickly flow into the bottom of the outer cylinder 1. When the liquid level of the urine sample reaches the scale mark, the small diameter opening at the bottom of the funnel-shaped inner cylinder 3 and the hole 8 on the buffer tube are all penetrated by the urine sample. At this time, the reaction chamber in the outer cylinder 1 forms a closed space; the urine sample in the funnel-shaped inner barrel 3 cannot continuously enter the reaction chamber under the action of the internal pressure of the reaction chamber, so that excessive urine sample is prevented from entering the reaction chamber.
