Description

Urine collector

Technical Field

The utility model belongs to the technical field of medical supplies, and particularly relates to a urine collector.

Background

At present, along with the gradual improvement of living standard and the continuous increase of working pressure, various diseases related to endocrine systems are more and more seriously harmful to the physical health of people, such as nephritis, kidney stones, urinary tract infection, prostatitis and other diseases, and the diseases at a conference can be diagnosed by the examination of urine routine, urine sediment and the like. The collection bottle for collecting urine clinically is generally cup-shaped or test tube-shaped, the cup-shaped collection bottle is generally shallower, the material is softer plastic, and the collection bottle is easy to spill in the process of collection and inspection, so that the environment is polluted, and cross infection is easy to occur. The opening of the test tube is smaller, so that the body fluid of a patient is inconvenient to collect, the body of the patient is often polluted, and the sample is inconvenient to store after collection.

Furthermore, the urine test item is also a conventional test item in hospitals and is also an important diagnosis basis. To obtain accurate urine specimen monitoring data, the originality must be maintained during collection, screening and testing. Therefore, medical staff is required to complete the collection of urine samples in the detection container in a closed environment, and secondary pollution is avoided. As urine is taken as a human body fluid, the urine has certain smell and pollution, a certain amount of time is needed from the completion of the sending of the urine to the completion of the detection of the sample, the odor is easy to be emitted, the working environment of medical staff is influenced, and the quantitative body fluid needs to be extracted in the detection process, so that the body fluid can be splashed out, thereby causing unnecessary biological pollution and even possibly infecting the medical staff.

For this purpose, the negative pressure urine collection device disclosed in chinese patent CN202229945U proposes a solution to the above-mentioned problems. In the prior art including the above patent, a negative pressure collection tube is sleeved outside a puncture needle in the process of collecting a body fluid sample by medical staff, and the body fluid enters the collection tube through a connecting tube. As can be seen from the contents of fig. 2 and fig. 4 of the patent, the connecting tube is a hollow tube, so that a certain gap is formed between the bottom of the connecting tube and the bottom of the cup body during the collection process, otherwise, a pressure difference cannot be formed, that is, medical staff cannot collect a body fluid sample. Therefore, when the mobile phone device is assembled, the connecting pipe is required to be ensured not to be in contact with the cup body, and once the assembly force is large or the assembly is disqualified, the detection efficiency and the service life of the device are affected. Therefore, designing a urine collector that is easy to assemble and that is easy to collect is an important technical problem to be solved by those skilled in the art.
