Problems solved by technology

Although the negative pressure urine collection device announced by Chinese Patent No. 201110275675.3 solves these problems, there are still some shortcomings. When extracting a small sample, it is necessary to unscrew the cup cover for extraction, and then tighten the cup cover. The operation is time-consuming and troublesome, and After the lid is completely opened, the chance of secondary pollution is increased

Embodiment Construction

[0018] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0019] The negative pressure urine collection cup cover shown in the accompanying drawing is a negative pressure urine collection cup cover that is convenient for micro-sampling, including the top 1 and the hanging edge 2 around the top 1; The mouth of the urine collection cup cooperates to form an annular seam 7 of a sealed structure; part of the top 1 inside the annular seam 7 extends downwards to form a cylindrical cavity 3 for installing a self-closing liquid delivery device; the top 1 is placed on the cylinder The periphery of the cavity 3 is also provided with a micro-sample extraction hole 5 and a flip cover 6; the micro-sample extraction hole 5 is a through hole; 5 fit closely to form a sealed structure.

[0020] The flip cover 6 is hingedly connected to the cover top 1 through a hinged connection structure. The hinged connecti...

Abstract

The invention discloses a negative pressure urine collection cup cover convenient for microscale sampling, and the negative pressure urine collection cup cover includes a cover top and a hanging brim hanging around the cover top; an annular seam allowance is formed in the inner side of the hanging brim, and is matched with a negative pressure urine collection cup rabbet to form a sealing structure; part of the cover top in the annular seam allowance extends downwards to form a cylindrical cavity for installation of a self-closing liquid conveying device; a microscale sample extraction hole and a turning cover are arranged the periphery of the cylindrical cavity on the cover top; the microscale sample extraction hole is a through hole; the turning cover is a thin-walled part, the middle part of the bottom wall of the turning cover extends downwards to form a bulge, and the bulge is tightly matched with the microscale sample extraction hole to form a sealing structure; the turning cover is in hinge joint with the cover top by a hinge joint structure; further improvement is that: the hinge joint structure comprises a hinge pin horizontally arranged on the periphery of the turning cover, and a hinge joint seat arranged on the top wall of the cover top; the hinge pin can be clamped in a hinge joint seat elastic card slot to rotate; and a turning piece is arranged on the periphery of the turning cover. The negative pressure urine collection cup cover can fast extract a microscale sample, and can significantly reduce the secondary pollution chance of urine in a negative pressure urine collection cup.

Description

technical field [0001] The invention belongs to the field of medical supplies, and in particular relates to a negative pressure urine collection cup cover. Background technique [0002] Urine test items are routine test items in hospitals and are also an important basis for diagnosis. To obtain correct urine specimen testing data, its originality must be maintained during the collection, submission and testing process. This requires medical staff to complete the collection of urine samples in the test container in a closed environment to avoid secondary pollution. Because urine has a certain smell and pollution that affects the hospital working environment, it is also required to seal the urine. Although the negative pressure urine collection device announced by Chinese Patent No. 201110275675.3 solves these problems, there are still some shortcomings. When extracting a small sample, it is necessary to unscrew the cup cover for extraction, and then tighten the cup cover. T...
