Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a blood sample storage and transportation device for use in a neonatal intensive care unit. Background Technology

[0002] In clinical diagnosis, timely and accurate testing of patient samples is of great help in early diagnosis and differentiation. For example, in neonatal intensive care, since infants often have immature organ function, potential genetic metabolic diseases or infection risks, early sample testing and screening can provide accurate basis for clinical decision-making.

[0003] A typical clinical sample submission process includes pre-test consultation, signing and collection of information collection forms and informed consent forms, sample collection, and submission. Blood samples are the most common type of sample, and can be categorized into liquid blood samples and dried blood smears, which differ significantly in their preservation. For liquid blood samples, blood collection tubes are generally used for collection and preservation, and they must be stored and transported at low temperatures. The standard procedure involves placing the blood collection tubes and ice packs together in a foam box, then sealing the child's information form and informed consent form in a plastic bag before submitting them together. Dried blood smears are obtained by dripping whole blood onto filter paper and drying it. They can be stored and transported at room temperature, are easy to preserve, and have good stability. Generally, dried blood smears packaged in a foam box and sealed in a plastic bag are submitted together with the paper materials in a plastic bag, but moisture must be prevented during submission.

[0004] Currently, due to limitations in storage and transportation conditions during the testing process, paper materials are easily damaged and susceptible to moisture, samples may be confused or contaminated, and different forms of samples need to be sent separately multiple times. This not only increases the workload of information verification and affects testing efficiency, but may also lead to sample invalidation and the need for re-collection. Therefore, the testing process is costly, unsafe, and inconvenient. Utility Model Content
