Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a saliva cup and a saliva reaction device. Background Technology
[0002] Saliva reaction devices, as convenient testing tools, are widely used in medical diagnosis, health monitoring, and other fields. Their core components include a saliva cup and a sampling rod. The saliva cup typically contains a test strip, which reacts chemically with the saliva sample to detect specific indicators. One end of the sampling rod is equipped with absorbent cotton for collecting the saliva sample. During testing, the user first uses the absorbent cotton to collect the saliva sample, then inserts the sampling rod into the saliva cup, bringing the absorbent cotton into contact with the bottom of the cup. This forces the saliva sample out, allowing it to come into contact with the test strip and react.
[0003] With the diversification of testing needs, the variety of test strips in saliva cups is gradually increasing to meet the testing requirements of different items. For example, a single saliva cup may contain multiple test strips for detecting different indicators such as blood glucose, hormone levels, and drug residues. However, existing saliva reaction devices have certain limitations in operation. Specifically, when the absorbent cotton squeezes the saliva sample, the sample often cannot be evenly distributed across the test strips, resulting in some test strips receiving insufficient sample contact, while others may receive excessive sample contact. This uneven contact not only affects the accuracy of the test results but may also lead to insufficient momentum of the test strip plate, further affecting the testing effect. Utility Model Content
[0004] The purpose of this invention is to provide a saliva cup and a saliva reaction device to alleviate the technical problem that different test strips in existing saliva reaction devices receive different amounts of saliva samples.
[0005] In a first aspect, the present invention provides a saliva cup, comprising: a cup body, wherein the interior of the cup body is provided with an abutting surface for contacting absorbent cotton;
[0006] At least three partition structures are provided along the circumference of the contact plane. Any two adjacent partition structures in the circumference form an opening in the circumference of the contact plane, and the width of each opening is approximately the same.
[0007] The saliva cup contains at least two test strips, with at least two different openings facing two different test strips respectively.
[0008] Furthermore, the bottom surface of the saliva cup is provided with an upwardly protruding boss, the top surface of the boss forms a contact plane, the bottom surface of the saliva cup and the contact plane are connected by a slope, and from top to bottom, the slope is inclined away from the center of the boss. The test strip is placed on the circumferential outer side of the boss, so that the saliva sample flowing out from the opening flows into the position of the test strip after passing through the slope.
[0009] Furthermore, the cup body includes a left side and a right side, the left side is provided with a left connecting structure, the right side is provided with a right connecting structure, both the left connecting structure and the right connecting structure are used to connect the test paper, and the test paper is equipped with at least two test strips.
[0010] At least one opening faces to the left and at least one opening faces to the right.
[0011] Furthermore, there are three openings facing the left.
[0012] There are three openings facing the right.
[0013] Furthermore, in the opening facing to the left, at least two openings are set at an angle;
[0014] In the opening facing to the right, at least two openings are set at an angle.
[0015] Furthermore, both the left and right connecting structures include two slots extending vertically, with the two slots spaced apart and facing opposite directions, for attaching the test paperboard.
[0016] Furthermore, the dividing structure extends along the depth direction of the cup body, and the dividing structure is columnar or sheet-like.
[0017] Furthermore, the surfaces of the partition structure facing the center of the contact plane are all arc-shaped, and all the arc-shaped surfaces are on the same circle.
[0018] Secondly, the present invention provides a saliva reaction device, including the aforementioned saliva cup;
[0019] The saliva reaction device also includes a sampling rod, one end of which is fitted with absorbent cotton.
[0020] Furthermore, the saliva reaction device also includes a lid for sealing the opening of the cup.
[0021] The other end of the sampling rod is connected to the bottom of the cup lid.
[0022] This utility model has at least the following advantages or beneficial effects:
[0023] The saliva cup provided by this utility model includes: a cup body, the inside of which is provided with an abutting plane for contacting absorbent cotton; at least three partition structures are provided along the circumference of the abutting plane, any two adjacent partition structures in the circumference of the abutting plane form an opening, and the width of each opening is approximately the same; at least two test strips are provided inside the saliva cup, and there are at least two different openings facing two different test strips respectively.
[0024] After sampling, the sampling rod is inserted into the cup, and then the absorbent cotton is brought into contact with the contact surface. Squeezing the sampling rod causes the absorbent cotton to be confined by the contact surface and the sampling rod, allowing the saliva sample to flow out evenly from each opening. The test strips located outside the openings can simultaneously receive the evenly released saliva sample. All test strips receive saliva at approximately the same time and in roughly the same amount, resulting in higher saliva utilization and resolving issues such as insufficient momentum in the test strip running plate.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0033] 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.
[0034] In the description of this utility model, 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 utility model is in use.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0035] 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.
[0036] In the description of this utility model, 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 utility model based on the specific circumstances.
[0037] like Figure 1 - Figure 4 As shown, the saliva cup provided by this utility model includes: a cup body 1, the top surface of the cup body 1 is open, and the four sides and bottom surface of the cup body 1 are closed.
[0038] The inside of the cup body 1 is provided with a contact surface 6, which is parallel to the opening, so as to facilitate contact with the absorbent cotton 8 that extends from top to bottom.
[0039] like Figure 2 As shown in this embodiment, test strips (not shown) are installed on the left and right sides of the cup body 1. Test strips are installed on the test strips, and multiple test strips can be installed on each test strip in the front-to-back direction.
[0040] The test strip can be connected to the cup body 1 through the slot 2. Specifically, taking the left side wall of the cup body 1 as an example, slots 2 are set at both the front and rear ends of the left side wall. The two slots 2 are spaced apart and the openings 4 face each other. The test strip is inserted into the slot 2 from top to bottom. The slot 2 prevents the test strip from moving to the right.
[0041] At least three partition structures 3 are provided along the circumference of the contact plane 6. The shapes of the partition structures 3 may be the same or different.
[0042] like Figure 3 As shown, any two adjacent separators 3 in the circumferential direction form an opening 4 in the circumferential direction of the contact plane 6. The saliva sample squeezed out from the absorbent cotton 8 flows out of the contact plane 6 through the opening 4 and flows towards the test strip.
[0043] The widths of each opening 4 are approximately the same. It should be noted that "approximately the same" means that the difference between the widths of any two openings 4 is less than a preset precision value. The preset precision value is related to the test type of the test strip. In this embodiment, the preset precision value a can be set to a range of a < 0.5 cm.
[0044] In this embodiment, there are six openings 4, with three openings 4 facing to the left and three openings 4 facing to the right, and they are symmetrical to each other.
[0045] Of the three openings 4 facing left, the middle opening 4 faces perpendicularly to the test strip on the left side, the front opening 4 is tilted forward, and the rear opening 4 is tilted backward, so that the three openings 4 can cover each test strip on the left side of the test strip. The same arrangement is made on the right side.
[0046] like Figure 2As shown, the bottom surface of the saliva cup has an upwardly protruding boss with a certain height. The top surface of the boss forms a contact plane 6. The bottom surface of the saliva cup and the contact plane 6 are connected by an inclined plane 5, which forms a slope. From top to bottom, the inclined plane 5 slopes away from the center of the boss. The test strip is placed on the circumferential outer side of the boss. The saliva sample squeezed out of the absorbent cotton 8 flows out from the opening 4, passes through the inclined plane 5, and flows down to the position of the test strip. The inclined plane 5 can accelerate the flow of the saliva sample to the test strip, thereby improving the fluidity of the saliva.
[0047] The dividing structure 3 extends along the depth direction of the cup body 1. The dividing structure 3 is columnar or sheet-like, as long as it can serve to divide and form multiple openings 4.
[0048] like Figure 3 and Figure 4 As shown, the surfaces of the separator 3 facing the center of the contact plane 6 are all arc-shaped, and all the arc-shaped surfaces are on the same circle. The inner diameter of this circle is slightly larger than the outer diameter of the cylindrical absorbent cotton 8, so that after the bottom surface of the absorbent cotton 8 contacts the contact plane 6, the circumferential sidewalls of the absorbent cotton 8 are squeezed against each arc surface, accelerating the precipitation of the saliva sample.
[0049] like Figure 4 As shown, the saliva reaction device provided by this utility model includes the saliva cup mentioned above; the saliva reaction device also includes a sampling rod 7, and one end of the sampling rod 7 is provided with absorbent cotton 8.
[0050] The saliva reaction device also includes a cup lid 9, which is used to close the opening of the cup body 1; the other end of the sampling rod 7 can be threaded to the bottom surface of the cup lid 9.
[0051] The device in this embodiment can maximize the squeezing of the solution through the separating structure 3 and the contact plane 6; by setting the openings 4 of approximately equal width, the solution can flow out evenly, so that the sample received on each test strip is relatively uniform, and the time and amount of saliva received by all test strips are basically the same. With the setting of the protruding inclined surface 5, the fluidity of saliva will be greatly improved, and the final saliva utilization rate will be higher, solving the problem of insufficient power of the test strip running plate.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 therein. Such 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 this utility model.
