Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a drying and storage box for dried blood spot collection strips. Background Technology
[0002] Menstruation refers to the periodic uterine bleeding that occurs in women after they enter puberty, caused by the stimulation of the ovaries on the uterine lining.
[0003] Dried blood spot (DBS) is a biosampling technique for collecting, drying, and storing small amounts of blood. It was first used by Robert Guthrie in 1963 for newborn phenylketonuria (PKU) screening. Compared to liquid blood matrices commonly used in clinical testing, dried blood spot technology offers advantages such as smaller blood volume, simpler operation, generally no need for freezing or refrigeration, and lower storage and transportation costs. It has been applied in newborn disease screening, epidemiological sample analysis, and drug development.
[0004] Existing patent CN109069134A discloses a device for collecting vaginal secretions for diagnosis, which involves collecting menstrual blood and other secretions using sanitary napkins. This involves collecting menstrual blood by placing filter paper strips in the sanitary pad and creating dried blood spots for testing. According to the "Standard Operating Procedure (SOP) for the Collection, Transportation, and Preservation of Dried Blood Spot Samples on Filter Paper," the blood filter paper strips need to be naturally dried at room temperature for at least 4 hours (at least 24 hours in humid climates) before drying and transportation. Currently, the collection and storage of dried blood spot filter paper strips are handled by professional testing institutions. In this patent, the dried blood spots on the test strips are transported and preserved by placing them in zip-lock bags or multi-barrier pouches. However, in daily life, users often use sanitary napkins to collect menstrual blood. Users do not have sufficient environment and conditions to dry the collection strips properly. Without proper drying, contamination may occur, affecting the accuracy of the test. Utility Model Content
[0005] The purpose of this invention is to provide a drying and storage box for dried blood spot collection strips, which facilitates the drying, storage, and transportation of dried blood spot collection strips collected from menstrual blood.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a drying and storage box for dried blood spot collection strips, comprising a box body and a top cover, wherein:
[0007] The box body includes a storage compartment and a drying compartment, which are interconnected.
[0008] The top cover is placed over the opening at the top of the box.
[0009] The beneficial effects of this utility model are as follows:
[0010] The dried menstrual blood spot collection strips are placed in the storage compartment inside the box. The drying compartment contains a desiccant to facilitate the drying, storage, and transportation of the menstrual blood spot collection strips, ensuring dryness throughout the entire storage and transportation process. An oxygen absorber can also be placed in the drying compartment; this absorber absorbs oxygen, slows down blood oxidation, and effectively inhibits the growth of mold and aerobic bacteria.
[0011] Furthermore, the storage compartment is equipped with multiple vertical and independent collection strip storage slots.
[0012] This allows for the simultaneous placement of multiple dried blood spot collection strips, thus resolving the issue of cross-contamination and contact between the strips.
[0013] Furthermore, the specific structure of the data collection strip storage slot is as follows:
[0014] The box contains a pair of vertically arranged bent plates, each pair of bent plates forming a data collection strip storage slot between their opposing V-shaped grooves. In practice, a pair of bent plates with multiple V-shaped grooves can be used, or multiple pairs of independently arranged bent plates with only one V-shaped groove can be used to form multiple data collection strip storage slots.
[0015] The space between a pair of V-shaped grooves is used as the storage slot for the collection strip. The dried blood spot collection strip is confined between the pair of V-shaped grooves, so that only two sides of the collection strip contact the slot wall, while the front and back sides of the collection strip do not contact the slot wall. This ensures that the collection strip itself is not contaminated by the slot wall, and at the same time, it makes the slot wall less likely to be soiled by the blood spots on the collection strip.
[0016] Furthermore, a soft rubber stopper is provided. The lower part of the soft rubber stopper is inserted into the opening at the top of the box. When the top cover is closed, the upper part of the soft rubber stopper is inserted into the top cover. The soft rubber stopper has a collection strip inlet.
[0017] The use of a soft rubber stopper improves the sealing and drying effect of the desiccant storage box.
[0018] Furthermore, the soft rubber stopper has multiple vertical collection strip insertion slots at its collection strip insertion inlet, which are aligned one-to-one with the collection strip storage slots in the storage compartment.
[0019] This makes it easy to place the dried blood spot collection strips into the corresponding collection strip storage slots one by one.
[0020] Furthermore, each of the aforementioned collection strip insertion slots is formed by a pair of V-shaped grooves on the two opposite sidewalls of the collection strip insertion inlet.
[0021] The acquisition strip insertion slot also adopts a V-shaped groove design, which has similar advantages to the acquisition strip storage slot design, and will not be elaborated here.
[0022] As a further preferred embodiment, the soft rubber stopper is further provided with multiple protruding soft rubber sealing rings on the outer peripheral wall of the stopper body.
[0023] The soft rubber sealing ring located at the bottom of the plug body seals with the opening at the top of the box body. When the top cover is closed, the soft rubber sealing ring located at the top of the plug body seals with the top cover, thus achieving a better sealing effect.
[0024] As a further preferred embodiment, the bottom of the soft rubber stopper is provided with a protrusion, which is located above the drying chamber.
[0025] The protruding part protrudes inward to contact the desiccant and deoxidizer, which can prevent the desiccant and deoxidizer from shaking.
[0026] As a further preferred embodiment, the top of the soft rubber stopper is connected to the inner wall of the upper cover via a flexible connecting strip.
[0027] This prevents the top cover from falling off during use. Attached Figure Description
