[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] like Figures 1 to 3 As shown in:

[0023] The disposable specimen collection cup of the embodiment of the present invention comprises a collection cup 1 and a sealing cover 2. The collection cup 1 is provided with a mixing chamber 11 and a collection chamber 12 communicating with each other. The specific structure can be as follows: a separator 5 is provided inside the collection cup 1, the separator 5 is arranged longitudinally, and its lower edge and left and right edges are respectively tightly connected to the inner bottom surface and inner side wall of the collection cup 1 (such as Figure 3The inner bottom surface and inner sidewall of the collection cup 1 are provided with a slot 16, and the lower edge and left and right edges of the separator 5 are respectively tightly stuck in the slot 16. ), dividing the inner cavity of the collection cup 1 into the mixing chamber 11 and the collection chamber 12; at the lower end of the separator 5, there are one or more channels 51 connecting the mixing chamber 11 and the collection chamber 12, and the channels 51 are provided with a filter 52; at the upper end of the separator 5, there is a liquid addition guide groove 53, the upper end of the liquid addition guide groove 53 is located directly below the second through hole 42 of the quantitative collection block 4, and the lower end of the liquid addition guide groove 53 is connected to the mixing chamber 11. The sealing cover 2 is a hard cover body, and a raised annular joint portion 21 is provided on the inner side thereof. The annular joint portion 21 is an elastic soft colloid (for example, a silicone body). When the sealing cover 2 is assembled on the upper end of the collection cup 1, the upper edge of the collection cup 1 is stuck between the circumferential edge of the sealing cover 2 and the annular joint portion 21, and the annular joint portion 21 is sealed and connected to the inner surface of the upper end of the collection cup 1; the inner end of the sealing cover 2 is provided with a collection spoon 3, the upper end of the collection spoon 3 is rotatably connected to the sealing cover 2, and the lower end is inserted into the mixing chamber 11. At the same time, the upper surface of the sealing cover 2 is provided with a first puncture membrane 22 and a second puncture membrane 23, and the first puncture membrane 22 and the second puncture membrane 23 are formed when the puncture spoon is inserted into the mixing chamber 11. The invention also includes an elastic soft film (e.g., a silicone film) that automatically contracts to a sealed state after needle insertion, and the first puncture membrane 22 faces the upper drive head 31 of the collection spoon 3 (the drive head 31 may be a drive engagement portion with a latch). The annular joint 21, the first puncture membrane 22, and the second puncture membrane 23 may also be an integrated structure (e.g., the annular joint 21, the first puncture membrane 22, and the second puncture membrane 23 are integrally molded using silicone material). The sealing cover 2 may also be an integrated structure with the annular joint 21, the first puncture membrane 22, and the second puncture membrane 23 (e.g., the annular joint 21, the first puncture membrane 22, and the second puncture membrane 23 are provided on the sealing cover 2 by a perfusion method). Thus, the collection cup 1 and the sealing cover 2 of the disposable specimen collection cup of the present invention have an excellent sealing effect, and the first puncture membrane 22 and the second puncture membrane 23 are absolutely sealed during use, preventing the specimen from leaking or emitting odor, thereby ensuring a clean, hygienic, and safe office environment.

[0024] like Figure 2 and 3The upper end of the collection cup 1 is provided with a quantitative collection block 4, which is provided with a first through hole 41 and a second through hole 42. The first through hole 41 and the second through hole 42 are located directly below the first puncture membrane 22 and the second puncture membrane 23, respectively. The lower ends of the first through hole 41 and the second through hole 42 are both connected to the mixing chamber 11. The lower end of the collection spoon 3 is inserted into the mixing chamber 11 through the first through hole 41. The first through hole 41 includes a coaxial upper through hole 43 and a lower through hole 44. The upper through hole 43 is a trumpet-shaped through hole with a diameter that gradually increases from bottom to top, and the lower through hole 44 is a trumpet-shaped through hole with a diameter that gradually increases from top to bottom. The lower end of the upper through hole 43 and the upper end of the lower through hole 44 have a smooth transition. The quantitative collection block 4 allows for simple quantitative sampling of the collection spoon 3, effectively improving mixing efficiency and effectiveness, resulting in faster testing and more accurate results.

[0025] like Figure 2 and 3 The quantitative collection block 4 is stepped, comprising a first step block 45 and a second step block 46. A first clearance 47 is formed above the second step block 46, and a second clearance 48 is formed below the first step block 45. The first through hole 41 and the second through hole 42 are respectively provided on the second step block 46 and the first step block 45. The drive head 31 at the upper end of the collection spoon 3 and the portion of the sealing cover 2 that rotatably connects the drive head 31 (i.e., the drive head 31 and the drive head positioning seat 24) are located within the first clearance 47. The upper end of the separator 5 and the upper end of the liquid addition guide groove 53 are located within the second clearance 48. Thus, the disposable specimen collection cup of the present invention has a more compact structure and a smaller volume.

[0026] like Figure 3 The inner bottom surface of the mixing chamber 11 is provided with a drainage surface 13 inclined toward the channel 51, and the inner bottom surface of the collecting chamber 12 is provided with an egg collecting groove 14, which greatly improves the effect of collecting eggs in the specimen, thereby improving detection.

[0027] like Figure 3 The outer surface of the collection cup 1 is provided with a detection and shooting surface 15, and the detection and shooting surface 15 is located outside the mixing chamber 11 and faces the spoon part 32 of the collection spoon 3 (that is, the detection and shooting surface 15 faces the position where the spoon part 32 collects the specimen), so that directional shooting can be achieved.

[0028] like Figure 2 and 3 The upper end of the spoon portion 32 of the collection spoon 3 is provided with one or more spikes 33. When the collection spoon 3 rotates in the mixing chamber 11 and drives the spoon portion 32 to rotate, the spikes 133 can enhance the mixing effect, making it easier to mix and separate the specimen.

[0029] The puncture and mixing method of the disposable specimen collection cup described in the present invention is specifically as follows: first, unscrew the sealing cover 2, hold the sealing cover 2, and use the spoon part 32 of the collection spoon 3 to take a sample. After sampling, insert the collection spoon 3 into the mixing chamber 11 (in this process, when the spoon part 32 passes through the first through hole 41 of the quantitative collection block 4, the excess specimen on the spoon part 32 will be blocked by the quantitative collection block 4, thereby achieving the effect of quantitative sampling); then tighten the sealing cover 2, and point the specimen on the spoon part 32 toward the detection and shooting surface 15, thereby achieving the effect of directional shooting; then place the disposable specimen collection cup on the test tube rack of the feces analyzer, and then the liquid adding needle of the feces analyzer pierces the second puncture membrane 23 to the mixing chamber 11 adds the diluent, and after the addition is completed, it is pulled out, and the second puncture membrane 23 automatically shrinks to a sealed state; then the mixing needle pierces the first puncture membrane 22 and matches the upper end driving head 31 of the collection spoon 3 to drive the collection spoon 3 to rotate and stir in the mixing chamber 11, and the specimen and the diluent are fully mixed (in this process, the first puncture membrane 22 shrinks and clings to the sleeve surface of the mixing needle, and the sleeve and the first puncture membrane 22 remain stationary, and the mixing needle rotates in the sleeve); finally, under the action of the drainage surface 13, the specimen passes through the filter screen 52 into the collection chamber 12 and is collected in the egg collecting tank 14, achieving a good egg collection effect, thereby improving detection for subsequent automatic collection by the feces analyzer.

[0030] In this way, by adopting the disposable specimen collection cup and the puncture mixing method of the present invention, automatic addition of diluent, automatic mixing and separation can be performed in a fully closed state, and the sealing is good, the automatic mixing and separation accuracy is good, and the egg collection effect is good. The collection is safe, reliable, hygienic, pollution-free, and the work efficiency is high. The problems of slow efficiency, cumbersome operation, and air pollution caused by manual operation are completely solved.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the design principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
