Disposable midstream urine sample collecting device

Abstract

The invention discloses a disposable midstream urine sample collecting device. According to the disposable midstream urine sample collecting device, an outer cup is arranged outside an inner cup in asleeving mode, and the openings of the inner cup and the outer cup are arranged upwards; the upper end of the inner cup and the upper end of the outer cup are in sealed connection to form an interlayer cavity between; the inner cup is composed of a containing cup and an earlystream urine collecting cup which are vertically connected through a round communicating port, a plugging floating ball is accommodated inside the earlystream urine collecting cup, and the diameter of the plugging floating ball is greater than that of the communicating port; the upper end of the containing cup is providedwith a midstream urine sample outflow port, and the containing cup is communicated with the interlayer cavity through the midstream urine sample outflow port; the upper end of the interlayer cavity isconnected with a urine overflow port which is formed outside the outer cup; the lower end of the interlayer cavity is communicated with a midstream urine sample transfer port which is formed outsidethe outer cup; the midstream urine sample transfer port is connected with a collecting tool. The disposable midstream urine sample collecting device can automatically collect midstream urine samples and meanwhile is accurate, simple and reliable; a patient does not need to interrupt a urination process; the disposable midstream urine sample collecting device can avoid the shortcoming that splashedurine can contaminate the patient and the environment; the disposable midstream urine sample collecting device is simple in structure, reasonable in design and low in cost.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable mid-section urine sample collection device. Background technique [0002] Urinalysis is a common auxiliary method for clinical medical disease screening. According to the requirements of the "Health Industry Standard Ws / T348-011 Guidelines for the Collection and Processing of Urine Specimens of the People's Republic of China", the urine sample submitted for inspection should be "middle urine sample" to ensure The liquid test data in the tested urine is accurate. [0003] However, the current clinically used urine collection device is generally a urine cup with a test tube for the patient to collect by himself. This device makes it difficult for the patient to control the sampling. It can only collect mixed urine or the front part of the urine, which cannot guarantee all urine samples. The collected urine sample is middle urine, and it is easy to cause urine ...
