Description

Technical Field

[0001] The utility model belongs to the technical field of medical consumables, and in particular relates to a feces quantitative collection device. Background Art

[0002] During the inpatient examination, stool testing is a routine test. Generally, the patient completes the collection and sending for testing by himself. For some patients who cannot do it by themselves, the stool can be collected by a caregiver or nurse, and then placed in a sample bottle for storage and sent for testing. Currently, stool collection is generally done with a collection spoon, but the collection spoon collects a small amount each time, and the caliber of the sample bottle is relatively small, so it is difficult to collect a sufficient amount of stool samples.

[0003] There are also some collection devices with complex structures, such as sampling shovels, which use a cylindrical sampling shovel to insert into the stool sample and then push it out to the sample bottle. However, it is impossible to visually see whether the stool in the cylinder is full, and quantitative collection cannot be achieved. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a feces quantitative collection device to solve the above technical problems.

[0005] The utility model adopts the following technical solutions:

[0006] The feces quantitative collection device comprises an outer cylinder and an inner shovel, wherein the outer cylinder is divided into two integrally formed upper and lower sections, wherein the caliber of the upper section is larger than that of the lower section, the top of the inner shovel is provided with a limiting guide round block matching the caliber of the upper section, the lower section of the outer cylinder and the bottom of the inner shovel are three evenly distributed arc pieces, the limiting guide round block is located in the upper section of the outer cylinder, the top of the limiting guide round block is provided with a connecting rod, and the end of the connecting rod is fixed with an operating cap.

[0007] Furthermore, a plurality of L-shaped limit grooves are provided at the port position of the upper section of the outer cylinder, and a guide column corresponding to the L-shaped limit groove is provided on the inner wall of the operating cap.

[0008] Furthermore, the ends of the arc pieces all have guide edges.

[0009] Furthermore, the inner wall of the operating cap has an internal thread, and the internal thread is located below the guide column.

[0010] The beneficial effects of the utility model are as follows: in this structure, when in use, the inner shovel is inserted from the top of the outer cylinder until the limiting guide circular block contacts the upper and lower transition positions of the outer cylinder to complete the limiting. At this time, the operating cap is rotated so that the six inner and outer arc pieces form a complete cylinder, and then the bottom is inserted into the fecal sample. After taking it out, the operating cap is rotated again so that the inner and outer arc pieces overlap, and then it can be intuitively seen whether the fecal sample is full. If an empty section is formed, the operating cap can be returned to its original position and inserted into the fecal sample again, so that quantitative fecal collection can be completed; after the collection is completed, the operating cap can be directly removed, the inner shovel is placed in the sample bottle, and the operating cap can be tightened. Therefore, the feces collection can be completed quantitatively through this device, and the feces can be sent to the sample for preservation and inspection. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0018] like Figure 1-5 As shown, the feces quantitative collection device provided in this embodiment includes an outer cylinder 1 and an inner shovel 2, wherein the outer cylinder 1 is divided into two integrally formed upper and lower sections, wherein the caliber of the upper section 11 is larger than the caliber of the lower section 12, the top of the inner shovel 2 is provided with a limit guide round block 3 matching the caliber of the upper section, the lower section 12 of the outer cylinder and the bottom of the inner shovel are three evenly distributed arc pieces 4, the limit guide round block 3 is located in the upper section 11 of the outer cylinder, the top of the limit guide round block 3 is provided with a connecting rod 5, and the end of the connecting rod 5 is fixed with an operating cap 6. In the figure, the ends of the arc pieces 4 are all provided with guide edges.

[0019] In this structure, the outer cylinder is formed in two sections, and the limit guide block on the top of the inner shovel matches the caliber of the upper section, and the limit guide block can move stably in the upper section. Three arc pieces are formed at the bottom of the lower section of the outer cylinder, and the angles of adjacent arc pieces are 120 degrees. At the same time, the bottom of the inner shovel is also three arc pieces arranged at 120 degrees. By operating the operating cap to rotate, the inner shovel can be driven to rotate. When the inner and outer arc pieces overlap, the internal space is exposed. When the inner and outer arc pieces are staggered, a complete cylinder is formed, and the cylinder is used to collect samples.

[0020] When in use, the inner shovel will be inserted from the top of the outer cylinder until the limiting guide block contacts the upper and lower transition positions of the outer cylinder to complete the limiting. This position is the lowest position of the inner shovel insertion. Turn the operating cap so that the six inner and outer arc pieces form a complete cylinder, and then insert the bottom into the stool sample. After taking it out, turn the operating cap again so that the inner and outer arc pieces overlap, so that you can visually see whether the stool sample is full. If an empty section is formed, you can return the operating cap and insert it into the stool sample again, so that quantitative stool collection can be completed. After the collection is completed, directly remove the operating cap, place the inner shovel in the sample bottle, and tighten the operating cap. Therefore, this device can be used to quantitatively collect stool, and the stool can be sent to the sample for preservation and inspection.

[0021] In order to facilitate the control of the rotation angle of the operating cap, a number of L-shaped limit grooves 13 are opened at the port position of the upper section 11 of the outer cylinder, and the inner wall of the operating cap 6 has a guide column 61 corresponding to the L-shaped limit groove 13. After the operating cap 6 is covered, the operating cap is slightly rotated so that the guide column falls into the L-shaped limit groove, and then rotated to the end of the L-shaped limit groove to complete the limit. At this time, the inner and outer arc pieces are staggered and can be collected. When the guide column rotates to the inside of the L-shaped limit groove, the inner and outer arc pieces overlap, and it can be directly observed whether enough is collected. Therefore, two states of limit can be achieved through the L-shaped limit groove, which is convenient for operation. In addition, there is a guide opening at the opening position of the L-shaped limit groove to facilitate the guide column to fall in.

[0022] In addition, the inner wall of the operating cap has an internal thread, which is located below the guide column. After the collection is completed, the inner shovel is withdrawn backwards, and the limit guide round block moves stably in the upper section of the outer cylinder until the inner shovel is completely withdrawn. After the inner shovel is placed in the sample bottle, the operating cap is screwed in, and the feces can be stored and sent for inspection.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
