Description

Sample collecting bottle with bracket

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a sample collecting bottle for collecting a liquid sample.

Background

There are a variety of clinical lateral flow immunoassay devices that can be used to detect the presence of analytes in a sample, such as hormones, sugars, adulterants, drugs of abuse, and the like. The detection of an analyte in a fluid sample is typically performed after the fluid sample is collected and added to a lateral flow immunoassay device.

Wherein the fluid sample may be any volume of fluid that is tested, examined, or studied. The fluid sample may be derived from any fluid, for example a bodily fluid such as saliva or blood or urine or other fluid to be tested such as a water sample from a source of contamination, a fluid sample from a beverage, etc.

Liquid samples are typically collected and absorbed using a collector bar having a collection element formed of an absorbent material such as a pad or sponge attached to one end of a plunger. The collection element allows a sufficient volume of sample fluid to be absorbed from the fluid source, the presence of sample fluid in the collection element causing the interior of the collection element to expand. The collection element typically retains the sample until the collection element is manipulated to release the sample. During detection, a fluid sample needs to be extruded out of a collecting element of a collecting rod and then added to a lateral flow immunoassay device; in some assays, the fluid sample is mixed with the buffer solution before the assay, or the fluid sample is squeezed out of the collection element of the collection rod and added to the buffer solution. For example, the novel coronavirus pneumonia test uses a sponge stick to suck certain saliva from the mouth of a test person, and then the saliva on the sponge is squeezed out into a lysis tube filled with lysate. And then dripping the cracked saliva sample on a detection test paper to finish detection.

In the prior art, a collection bottle is used to collect a fluid sample on a collection element, i.e., the collection element end of a collection rod is inserted into the collection bottle, and the collection element is pressed against the sidewall or bottom of the collection bottle body to cause the fluid sample to flow out of the collection bottle for sample collection. There is a problem in that the fluid sample on the collecting member cannot be sufficiently squeezed out, or when there is buffer in the collection vial, the collecting member absorbs and carries away a portion of the buffer, resulting in an insufficient amount of subsequent test fluid.

In some embodiments, the bracket 3 is a cross-shaped structure formed by crossing the transverse baffle 31 and the longitudinal baffle 32; the top of the transverse baffles 31 and the longitudinal baffles 32 are located in the middle portion 12 of the bottle body. In some embodiments, the top ends of the transverse baffles 31 and the longitudinal baffles 32 are provided with connecting rings (not shown) for increasing the contact surface with the collecting element 21 and ensuring that the liquid sample is sufficiently squeezed out.

In order to ensure the stable fixation of the holder 3 in the bottle body 10 and to satisfy the sequence of the liquid flow in the bottle body 10, the connection between the lateral barrier 31 and the longitudinal barrier 32 and the inner sidewall and the bottom of the bottle body can be adjusted. For example, in other embodiments, at least one end of the transverse baffle is not connected to the interior sidewall of the bottle, and at least one end of the longitudinal baffle is not connected to the interior sidewall of the bottle. For another example, in some embodiments, one end of the transverse baffle is connected to the inner side wall of the bottle body, at this time, the other end of the transverse baffle is not connected to the inner side wall of the bottle body, and the bottom of the transverse baffle is connected or not connected to the bottom of the bottle body; the vertical baffle can be connected with the bottle inside wall by one end or both ends are not connected with the bottle inside wall, and the bottom of the vertical baffle is connected with the bottom of the bottle or not connected with the bottle. For another example, in other embodiments, the transverse baffle is connected to the inner side wall of the bottle body at one end, and is not connected to the inner side wall of the bottle body at the other end; both ends of the longitudinal baffle are not connected with the inner side wall of the bottle body, and at the moment, the bottoms of the transverse baffle and the longitudinal baffle can be respectively connected with or not connected with the bottom of the bottle body; under the structure, the liquid can fully flow at the bottom of the bottle body, so that the flow of the liquid sample and the mixing of the buffer solution and the liquid sample are ensured.

In some embodiments, the holder 3 is integrally formed and fixed to the bottom of the bottle 10 or the inner sidewall of the bottle.

In use, as shown in fig. 6-9, a plunger of the collection wand is held by a hand to place the collection wand, having collected a fluid sample (e.g. saliva sample) on the collection member 21, over the opening 14 of the sample collection bottle 100 and inserted into the sample collection bottle 100, with the collection member contacting the top of the holder 3, the collection wand is pushed further downward, the collection member is squeezed by the top of the transverse and longitudinal baffles, the fluid sample flows out of the collection member, flows into the vial 10 along the top of the transverse and longitudinal baffles, and the squeezing is continued with increased squeezing force until the collection member is compressed to a maximum and the fluid is no longer flowing out, and the collection wand is withdrawn.

In other embodiments, the bracket 3 comprises three support rods and a ring (not shown) connected to the top of the support rods, and the bottom of the support rods is fixed to the bottom of the bottle body. Furthermore, a cross-shaped or # -shaped supporting net (not shown in the figure) is arranged in the circular ring. When the collecting element is inserted into the bottle body and then contacts with the circular ring and the supporting net to be extruded, the extruded liquid directly drops into the bottle body or flows into the bottle body along the supporting rod, and the collection of the liquid sample is realized.

The sample collecting bottle is suitable for medical diagnosis processes requiring sample preservation or pretreatment by using reagents before detection, for example, the sample collecting bottle can be used as a lysis bottle pre-filled with lysis solution for lysing bacteria, viruses and the like in a sample.
