Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an integrated nasopharyngeal swab sampling tube. Background Art
[0002] The original sampling tube requires two tubes (nasal / pharyngeal swab sampling tube and specimen preservation liquid tube). During operation, the operator needs to break the swab strip and then place it in another test tube with specimen preservation liquid, which is time-consuming and laborious. Moreover, during the process of breaking the swab strip, solution splashing is likely to occur, and the operator is prone to cross-infection and environmental pollution. Content of the Utility Model
[0003] The purpose of the utility model is to provide an integrated nasopharyngeal swab sampling tube with simple structure, convenient operation, safety and reliability.
[0004] To achieve the above purpose, the utility model adopts the following technical solutions:
[0005] An integrated nasopharyngeal swab sampling tube is composed of an outer test tube, an inner test tube, a limiter and a swab;
[0006] The outer test tube includes an outer tube body, an opening sleeve extending upward along the inner edge of the top tube orifice, a reagent contained in its bottom and a reagent isolation film arranged on the liquid surface of the reagent;
[0007] The inner test tube includes an inner tube body, a limiting ring surrounding the outer edge of the top tube orifice, and a plurality of leakage holes surrounding the bottom;
[0008] The limiter is sleeved on the opening sleeve;
[0009] The swab includes a top cover, a swab rod connected to the inner end face of the top cover, and a swab head located at the bottom of the swab rod;
[0010] The inner test tube is located inside the outer test tube and is supported on the upper port of the limiter or the opening sleeve through its limiting ring. The swab is located inside the inner test tube and is supported on the upper port of the inner test tube through its top cover.
[0011] Further, the reagent isolation film is a plastic film.
[0012] Further, the bottom of the inner tube body is in a conical structure, and a pointed cone head is provided at its bottom end. The leakage holes are located on the bottom surface above the pointed cone head.
[0013] Advantages of the Utility Model:
[0014] 1. Combine the original two tubes into one tube. The newly added reagent isolation membrane is a plastic film, which is easy to obtain and has a low cost. After sampling, there is no need to break the swab strip, reducing the workload of medical staff, saving time and effort, avoiding cross-contamination caused by splashing of the solution when medical staff break the swab strip, and protecting medical staff;
[0015] 2. Avoid environmental pollution;
[0016] 3. Economical and practical, easy to operate. Description of the Drawings
