Description

Fast screening collection and detection device

This creation is about a quick-screen collection and detection device, in particular a quick-screen collection and detection device with a detection liquid accommodating part, a test paper accommodating part, and a sampling probe part.

Fast screening technology has the advantages of being fast and cheap, and has been widely used in various technical fields in recent years, such as disease screening, pregnancy testing, food safety inspection and other fields. Generally speaking, the test method used in rapid screening includes the steps of dipping the sample with a test stick, then mixing the sample with the test solution, and finally using the test paper to absorb the test solution to obtain the test result. However, the entire detection process involves a variety of devices, which not only causes inconvenience in use, but also increases the risk of contamination of the specimen, and the problem of splashing of the specimen and the detection liquid is prone to occur during operation.

In addition, most of the conventional techniques use dry test paper to absorb the test liquid, and use the capillary phenomenon to make the test liquid slowly pass through the test line on the test paper for testing. However, the detection speed of the aforementioned methods is relatively slow, and further improvements are still needed to better meet the goal of rapid display of results pursued by the fast screening technology.

Therefore, the purpose of this creation is to provide a quick-screen collection and detection device that is convenient to use and can quickly present test results. A test liquid containing space; a test paper containing part having a test paper containing space for containing the test paper; and a sampling probe part having a channel for the detection liquid to flow out of the sampling probe part, Wherein, the two ends of the test paper accommodating part are respectively connected with the detection liquid accommodating part and the sampling probe part, the test paper accommodating space is connected to the channel of the sampling probe part, and the detection liquid accommodating The space is separated from the test paper accommodating space by a temporary barrier, which can be manually removed or destroyed, so that the test solution accommodating space is connected to the test paper accommodating space.

In some implementation aspects of this creation, the temporary barrier can be destroyed by applying pressure to it, so that the test solution accommodating space is connected to the test paper accommodating space. Preferably, the temporary barrier is a thin film.

In some implementation aspects of this creation, the test paper accommodating part has an opening and a correspondingly provided opening cover, and the test paper can be inserted or taken out through the opening.

In some implementation aspects of this creation, the test paper accommodating part is made of transparent material.

In some implementation aspects of this creation, the test paper accommodating part has an interpretation window for interpreting the test result.

In some implementation aspects of this creation, the quick-screen collection and detection device further includes a cover for protecting the sampling probe part and receiving the detection liquid flowing out of the channel of the sampling probe part.

The following will further explain some of the specific implementation aspects of this creation with reference to the attached drawings; however, without departing from the spirit of this creation, this creation can still be practiced in many different forms, and the protection scope of this creation should not be interpreted as Limited to the specific implementation aspect.

Unless otherwise specified, "a", "the" and similar terms used in this specification and the scope of the patent application shall be understood to include singular and plural forms.

The effect of this creation compared with the prior art is to provide an improved quick screening collection and detection device, which has the advantages of convenient use, low risk of specimen contamination, and less prone to splashing during operation. In addition, most of the conventional techniques use dry test paper to absorb the test liquid, and use the capillary phenomenon to make the test liquid slowly pass through the test line on the test paper for testing. In contrast, the quick-screen collection and detection device of this invention first wets the test paper with the test liquid, so that the subsequent test liquid with the sample passes through the test paper in a diffusion manner. Compared with the capillary phenomenon, the diffusion speed is faster. Therefore, the fast screening collection and detection device of the invention also has the advantage that the detection results can be obtained quickly. The following provides a detailed description of this creation's quick screening collection and detection device and its related applications.

The two ends of the test paper accommodating portion 111 are respectively connected to the test solution accommodating portion 101 and the sampling probe portion 121, the test paper accommodating space 112 is connected to the channel 122 of the sampling probe portion 121, and the test solution accommodating space 102 is connected to The test paper accommodating space 112 is separated by a temporary barrier 131.

The temporary blocking member 131 can provide a temporary blocking effect, and can be manually taken out or destroyed by applying pressure when the quick-screen collection and detection device is in use, so that the test solution containing space 102 and the test paper containing space 112 are connected. Figures 2 and 3 respectively illustrate schematic diagrams of designing destructible temporary barriers in different ways. In the aspect illustrated in FIG. 2, the temporary blocking member 131 can be broken by bending the quick-screen collection and detection device, so that the detection solution accommodating space 102 and the test paper accommodating space 112 are in a connected state. The barrier can be, for example, a thin film. In the aspect illustrated in FIG. 3, the temporary barrier 131 can be destroyed by the squeezing action along the axial direction of the quick-screen collection and detection device, so that the detection liquid accommodating space 102 and the test paper accommodating space 112 are in a connected state The temporary barrier may be a thin film, for example. However, the design of temporary barriers in this creation is not limited to the above specific aspects. Those with general knowledge in the technical field of this creation can make other alternative designs based on their general knowledge after viewing the disclosure of the specification of this case, such as changes.

Therefore, the test paper accommodating portion 111 may be provided with an openable and closable opening as required, and may have a correspondingly provided opening cover, so that the test paper can be inserted or taken out through the opening. The opening or opening cover is preferably designed with a sealing strip to improve airtightness.

As shown in FIG. 4, in addition to the above-mentioned components, the quick-screen collection and detection device 1 may be equipped with a cover 141. When not in use, the sampling probe 121 is placed in the cover 141 to avoid contamination by foreign objects. In addition, the detection liquid is sealed in the detection liquid accommodating space 102 by a temporary barrier 131. During use, the user can remove the cover 141 to expose the sampling probe part 121 for specimen collection. After the sample collection is completed, the sampling probe part 121 is placed in the cover body 141 again, and the temporary blocking member 131 is destroyed by bending the test liquid accommodating part 101 and the test paper accommodating part 111 to make the test liquid accommodating space 102 It is connected to the test paper accommodating space 112, allowing the test liquid to flow from the test liquid accommodating space 102 into the test paper accommodating space 112 and soak the test paper placed in the test paper accommodating space 112. Then, the test liquid flows out through the channel 122 of the sampling probe part 121 communicating with the test paper accommodating space 112, and is contained in the cover 141. The detection liquid is mixed with the collected specimen in the cover 141, and returns to the test paper by the diffusion phenomenon, thereby displaying the detection result.
