Description

Portable liquid sample collection device

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a portable liquid sample collecting device.

Background

In medical testing, in order to determine the physical condition of a patient, a clinical sample of the patient needs to be collected for testing, and a saliva sample or a urine sample is common. Particularly, aiming at the detection of a saliva sample, the epithelium of the human oral mucosa is a stratified squamous epithelium, and has the characteristics of vigorous metabolism, quick renewal and easy shedding. These shed cells have the entire human genomic DNA sequence. Compared with the traditional method for extracting blood and collecting DNA, the method for collecting the saliva DNA sample is a method for obtaining DNA without harm and pain to human bodies, discomfort and fear to the collected person are not easy to cause, the method cannot cause any discomfort to the collected person and is easy to accept, so that the sampling range of gene research can be enlarged to the maximum extent, and the method is particularly suitable for large-scale crowd investigation in molecular epidemiology. Therefore, the saliva test is increasingly focused on the clinic.

Saliva must be collected and stored in advance for saliva detection, however, the possibility of external contamination of the sample is introduced due to a large number of manual operation steps of a user during saliva sample collection, and deviation of detection results is caused. However, the existing saliva collecting device has the defects of inconvenient operation, difficult collection, easy pollution, non-uniform sampling amount and the like, and brings great troubles to clinical detection. For example, saliva samples are collected mainly by using a cotton swab to obtain oral mucosa epithelial cells, and the method is relatively complicated, and the collected DNA is small in quantity and not easy to store.

In addition, some other medical detection samples, such as the collection of urine samples, also have the above-mentioned problem, and the collection of urine sample at present mainly adopts disposable plastic cup collection, and not only the manual operation is inconvenient, and open collection method easily causes the pollution or the loss of urine sample moreover.

Therefore, it is urgently needed to provide a medical liquid collector which is convenient to operate, not easy to pollute and easy to store.
