Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a sampling reaction dispensing integrated bottle. Background Technology

[0002] With the continuous advancement of medical technology, more and more diseases can be quickly diagnosed through self-testing, greatly improving the convenience and efficiency of diagnosis. Self-testing technology is widely used in areas such as blood glucose monitoring, pregnancy testing, and infectious disease screening, providing patients with timely health information.

[0003] However, for tests that require blood, a number of parts are often needed to complete the steps of blood collection, lysis, dripping, and testing, which makes the testing process relatively cumbersome and prone to errors. Summary of the Invention

[0004] The purpose of this invention is to provide a sampling reaction dropper integrated bottle to alleviate the technical problem that may lead to misoperation in the existing blood testing process, which involves multiple parts cooperating to achieve the test.

[0005] The present invention provides a sampling reaction droplet integrated bottle, comprising:

[0006] The bottle body has an opening, and a first connecting structure is provided on the outer wall of the opening end of the bottle body. The bottle body is used to contain the reaction liquid.

[0007] A bottle cap includes a connecting end and a sampling end disposed opposite to each other. The bottle cap has an internal channel penetrating the end face of the connecting end and the end face of the sampling end. The channel includes a sampling segment extending from the sampling end toward the connecting end, the sampling segment being used to absorb a sample. From the connecting end toward the sampling end, the connecting end is provided with a second connecting structure with its interface facing the sampling end, and a third connecting structure with its interface facing the connecting end.

[0008] When the first connecting structure is connected to the third connecting structure, the channel is connected to the bottle body through the port of the connecting end, and the sampling reaction adding integrated bottle is in a adding posture; when the first connecting structure is connected to the second connecting structure, the sampling end is located inside the bottle body, and the sampling reaction adding integrated bottle is in a reaction posture.

[0009] Furthermore, the interior of the sampling section is made of hydrophilic material or has undergone hydrophilic treatment.

[0010] Furthermore, the channel includes a mutation segment, one end of which is connected to the inner port of the sampling segment, and the cross-sectional area of ​​the end of the mutation segment connected to the sampling segment is greater than the cross-sectional area of ​​the inner port of the sampling segment.

[0011] Furthermore, a groove is provided on the end face of the connecting end, and the channel penetrates the bottom surface of the groove, the groove being used to install the filter element.

[0012] Furthermore, the first connection structure includes external threads disposed on the outer wall of the bottle body;

[0013] The second connection structure includes a first skirt that is arranged circumferentially around the connection end and protrudes toward the sampling end, wherein the inner wall of the first skirt is provided with a first internal thread corresponding to the external thread;

[0014] The third connection structure includes a second skirt that is arranged circumferentially around the connection end and protrudes toward the side away from the sampling end, and the inner wall of the second skirt is provided with a second internal thread corresponding to the external thread.

[0015] Furthermore, an annular protrusion is provided on the end face of the connecting end, and the channel is located inside the annular protrusion. The annular protrusion is used to abut against the end face of the opening of the bottle body when the sampling reaction dropping integrated bottle is in the dropping posture.

[0016] Furthermore, in the bottle cap, the portion located inside the first skirt edge is provided with a thickened portion that protrudes outward in the circumferential direction. The thickened portion is used to abut and seal against the inner wall of the opening of the bottle body when the sampling reaction adding integrated bottle is in the reaction posture.

[0017] Furthermore, the opening of the bottle body is provided with a sealing film.

[0018] Furthermore, the sampling reaction dropper also includes a protective cap, which is used to seal the sampling end.

[0019] Furthermore, the bottle body is made of a soft material so that it can be squeezed and deformed.

[0020] This invention has at least the following advantages or beneficial effects:

[0021] The sampling reaction dispensing integrated bottle provided by the present invention includes: a bottle body and a bottle cap. The bottle body has an opening, and a first connecting structure is provided on the outer wall of the opening end of the bottle body. The bottle body is used to contain a reaction liquid. The bottle cap includes a connecting end and a sampling end disposed opposite to each other. A channel is provided inside the bottle cap, penetrating the end face of the connecting end and the end face of the sampling end. The channel includes a sampling segment starting from the sampling end and extending towards the connecting end, and the sampling segment is used to absorb a sample. From the connecting end toward the sampling end, the connecting end is provided with a second connecting structure with its interface facing the sampling end, and a third connecting structure with its interface facing the connecting end. When the first connecting structure and the third connecting structure are connected, the channel is connected to the bottle body through the port of the connecting end, and the sampling reaction dispensing integrated bottle is in a dispensing posture. When the first connecting structure and the second connecting structure are connected, the sampling end is located inside the bottle body, and the sampling reaction dispensing integrated bottle is in a reaction posture.

[0022] This integrated sampling, reaction, and dropping device allows for the continuous execution of three steps—sampling, reaction, and dropping—simplifying the testing process and reducing the chance of errors. Specifically, in use, the user draws a sample from the sampling end of the cap, which enters the channel, completing the sample collection step. The sampling end of the cap is then inserted into the bottle body, connecting the first and second connecting structures, allowing the sample to enter. The bottle is then shaken to ensure thorough mixing of the sample with the reaction solution, completing the reaction step. Next, the cap is removed and flipped over, connecting the first and third connecting structures, allowing the sample to be dropped onto the test plate from the sampling end through the channel on the cap, initiating the test and completing the dropping step.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0039] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] like Figure 1 and Figure 6 As shown, the sampling reaction dispensing integrated bottle provided by the present invention includes: a bottle body 1, the top of the bottle body 1 having an opening, and a first connecting structure provided on the outer wall of the opening end of the bottle body 1, the first connecting structure being an external thread 11, the bottle body 1 being used to contain the reaction liquid. The bottle body 1 can be made of a soft material so that the bottle body 1 can be deformed by compression.

[0041] The integrated bottle also includes a bottle cap 2, which has an overall slender conical structure. The bottle cap 2 includes a connecting end 21 and a sampling end 22 that are arranged opposite to each other. The sampling end 22 is thinner and the connecting end 21 is thicker.

[0042] like Figure 4 As shown, the bottle cap 2 has a channel 3 inside that passes through the end face of the connecting end 21 and the end face of the sampling end 22. The channel 3 includes a sampling section 31 that starts from the sampling end 22 and extends toward the connecting end 21. The sampling section 31 is made of hydrophilic material or has been treated with hydrophilicity. The sampling section 31 is used to absorb samples.

[0043] From the direction of the connecting end 21 toward the sampling end 22, the connecting end 21 is provided with a second connecting structure with its interface facing the sampling end 22, and a third connecting structure with its interface facing the connecting end 21. When the first connecting structure and the third connecting structure are connected, the channel 3 is connected to the bottle body 1 through the port of the connecting end 21, and the sampling reaction dispensing integrated bottle is in a dispensing posture; when the first connecting structure and the second connecting structure are connected, the sampling end 22 is located inside the bottle body 1, and the sampling reaction dispensing integrated bottle is in a reaction posture. That is, the bottle cap 2 is set as a bidirectional bottle cap 2, with different functions in different directions. When the sampling end 22 faces outward, it is in a dispensing posture for sample dispensing; when the sampling end 22 faces inward, it is in a reaction posture for sample mixing and lysis.

[0044] The length of sampling segment 31 is fixed, therefore the maximum sample collection volume is fixed. To avoid oversampling, channel 3 includes a transition segment 32 located inside sampling segment 31. One end of the transition segment 32 is connected to the inner port of sampling segment 31, and the cross-sectional area of ​​the end of the transition segment 32 connected to sampling segment 31 is larger than the cross-sectional area of ​​the inner port of sampling segment 31. At the connection between sampling segment 31 and transition segment 32, a stepped structure is formed due to the difference in cross-sectional area, resulting in a sudden increase in diameter. This prevents the sample from rising into the interior of transition segment 32 under the influence of surface tension, thus ensuring quantitative sample collection and guaranteeing that the sample volume meets testing requirements.

[0045] like Figure 2 and Figure 3 As shown, a groove is provided on the end face of the connecting end 21, and the channel 3 penetrates the bottom surface of the groove. The groove is used to install the filter element 4. When dripping, the liquid flowing out from the channel 3 must be filtered by the filter element 4. The filter element 4 is used to filter impurities and air bubbles in the sample and to prevent the sample from splashing out.

[0046] The second connection structure includes a first skirt 23 that is circumferentially surrounding the connection end 21 and protruding towards the sampling end 22. The inner wall of the first skirt 23 is provided with a first internal thread 231 corresponding to the external thread 11. The third connection structure includes a second skirt 24 that is circumferentially surrounding the connection end 21 and protruding away from the sampling end 22. The inner wall of the second skirt 24 is provided with a second internal thread 241 corresponding to the external thread 11. The mating interfaces of the first skirt 23 and the second skirt 24 face opposite directions, thereby enabling the bottle cap 2 to be connected to the bottle body 1 in both directions. In both states, the sampling end 22 is located on the inner and outer sides of the bottle body 1, respectively.

[0047] like Figure 5As shown, an annular protrusion 211 is provided on the end face of the connecting end 21, and the channel 3 is located inside the annular protrusion 211. The annular protrusion 211 is used to abut against the end face of the opening of the bottle body 1 when the sampling reaction dropping integrated bottle is in the dropping posture, so as to achieve a seal and prevent sample leakage.

[0048] like Figure 5 As shown, in the bottle cap 2, the portion located inside the first skirt 23 is provided with a thickened portion 212 that protrudes outward in the circumferential direction. The outer diameter of the thickened portion 212 is greater than or equal to the inner diameter of the opening of the bottle body 1. The thickened portion 212 is used to extend into the opening of the bottle body 1 when the sampling reaction adding integrated bottle is in the reaction posture, and to abut against the inner wall of the opening of the bottle body 1 to seal and prevent leakage.

[0049] like Figure 6 As shown, the opening of the bottle body 1 is provided with a sealing film 5 to ensure that the reaction liquid does not leak. When using it, you can simply tear off the sealing film 5 by hand.

[0050] The sampling reaction dropper also includes a protective cap 6, which is used to seal the sampling end 22. Before use, the sampling end 22 is protected from contamination, and after use, it is used to ensure that the sample does not contaminate the environment.

[0051] Usage steps:

[0052] During packaging, the bottle cap 2 and the bottle body 1 can be set separately or assembled together.

[0053] Remove the bottle cap 2 from the bottle body 1 (skip this step if the packaging is separate), and peel off the sealing film 5 pasted at the opening of the bottle body 1 for later use.

[0054] Prick your finger with a collection needle (or use a collected blood sample), remove the protective cap 6 from the bottle cap 2, and contact the blood with the outer port of the sampling end 22. The blood sample is automatically drawn into the sampling section 31.

[0055] like Figure 4 As shown, gently squeeze bottle 1 while using the second connecting structure of bottle cap 2 to connect bottle 1, restore bottle 1 to its natural state, and the blood sample is drawn into bottle 1. Shake the entire device to fully disperse the blood sample in the reaction solution.

[0056] like Figure 2 As shown, unscrew the cup cap, connect the bottle body 1 with the third connecting structure of the bottle cap 2, invert the device, squeeze the bottle body 1, and the sample drips out from the outer port of the sampling end 22.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
