Description

Technical Field

[0001] This utility model belongs to the field of biological detection technology, specifically relating to a saliva detection pen. Background Technology

[0002] Saliva is considered a major component of the oral cavity's host defense system, forming the first line of defense against physical, chemical, and biological stimuli. With advancements in genomics, proteomics, and metabolomics detection and quantification methods, saliva has become a primary sample source for detecting disease biomarkers. As a "mirror" of the body, saliva can be used for non-invasive diagnosis and monitoring in various fields, including oral diseases, drug treatment, and infectious diseases.

[0003] Devices that use saliva testing for disease diagnosis commonly use saliva test cards, but traditional saliva test cards can only detect one type of disease.

[0004] Therefore, there is an urgent need for a saliva detection structure that can detect multiple diseases simultaneously, is easy to use, and has a stable structure. Summary of the Invention

[0005] The purpose of this application is to provide a saliva testing pen that aims to solve the problems of existing testing methods that require different test cards for testing multiple indicators, unstable test card structure, inability to be used with various sample suction devices and various types of test strips, resulting in limited test card products, high product testing costs, and easy user confusion due to the variety of test cards.

[0006] A saliva testing pen includes: a housing, a sample suction element, a test strip, and a cap. The housing includes a first retainer and a second retainer, each of which has at least one display window and at least one positioning element. The test strip is fixed to the positioning element, and the sample suction element is disposed at one end of the housing near the cap. One of the first retainer and the second retainer is provided with a locking claw, and the other of the first retainer and the second retainer is provided with a locking buckle. The locking claw and the locking buckle engage to form the housing.

[0007] In this invention, the engagement of the snap fastener and the snap claw makes it possible for the first and second retaining shells to be aligned with very precise alignment, making positioning easier during engagement. The snap fastener and the snap claw engage more tightly, facilitating assembly in the production process, improving product production efficiency, and saving product costs.

[0008] Furthermore, the engaging claw protrudes from the edge of one of the first and second retaining shells, and the engaging buckle is recessed into the edge of the other of the first and second retaining shells.

[0009] Furthermore, the engaging claw includes a locking portion and a claw portion, and the latch includes a clearance portion and a latch portion. The locking portion and the clearance portion fit tightly together, and the claw portion extends into the latch portion, so that the first and second locking shells have interaction forces in both the horizontal and vertical directions. When the first and second locking shells are engaged, the entire locking shell structure is more stable.

[0010] Furthermore, the positioning element includes a positioning groove and a positioning stop. The positioning stop is located on the upper side of the positioning groove and extends horizontally into the positioning groove. The distance between the positioning stops on adjacent groove sides on the same horizontal plane is less than the width of the detection strip. The detection strip can pass through the gap between the positioning stops vertically or obliquely and is fixed in the positioning groove. At the same time, since the gap between the positioning stops is less than the width of the detection strip, the complex partition design is eliminated, reducing the risk of the detection strip leaving the positioning groove and reducing the probability of the detection strip contacting the detection strip on another housing.

[0011] Furthermore, the positioning component also includes a positioning baffle that abuts against the end of the absorbent pad of the detection strip. The positioning baffle is located on the upper part of the edge of the positioning groove. The positioning baffle is a plane and perpendicular to the adjacent groove edge. The positioning baffle can reduce the risk of the detection strip leaving the positioning groove and reduce the probability of the detection strip contacting the detection strip on another housing.

[0012] Furthermore, at least one set of sample suction baffles is provided on both sides of the first and / or second clasps that contact the distal end of the sample suction element. The gap between the at least one set of sample suction baffles is smaller than the width of the sample suction element. This can position the sample suction element and prevent excessive contact with the sample suction pad of the test strip, thus affecting the speed of sample feeding into the test strip.

[0013] Furthermore, a positioning post is provided on the first and / or the second housing, which engages with the sample suction device to assist in positioning and fixing the sample suction device in place.

[0014] Furthermore, the sampling element is a solid sampling rod, and the outer side of the sampling rod contacts the sampling pad of the detection strip.

[0015] Furthermore, the sampling element is a hollow sampling ring, and the inner side of the sampling ring is in contact with the sampling pad of the detection strip.

[0016] Furthermore, the first and / or second housings are provided with a movable cover plate, which locks the outer side of the sampling ring. The cover plate can better accommodate the sampling ring when it is fitted onto the test strip, and the test strip does not need to be adjusted, making it easier to assemble the saliva test pen.

[0017] Compared with the prior art, the beneficial effects of this application include:

[0018] This invention features a locking claw on the first housing and a locking buckle on the second housing. The engagement of the locking claw and buckle creates interaction forces between the first and second housings in both the horizontal and vertical directions, making positioning easier, the housing structure more compact and stable, and the production process simpler. The use of positioning stops and / or positioning baffles eliminates the need for complex partition designs, effectively isolating the test strips and reducing the risk of the test strips completely leaving the positioning groove. At least one set of sample-absorbing ribs is provided on both sides of the housing where it contacts the sample absorbent. Since the gap between the sample-absorbing ribs is smaller than the width of the sample absorbent, the placement of the sample absorbent can be positioned and fixed. The movable cover design allows the housing to assemble various sample absorbents and match different types of test strips, making the assembly of the saliva testing pen more convenient and versatile.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The terms “vertical,” “both sides,” “side,” “top,” “inner,” “outer,” “both sides,” “upper,” “far end,” “proximal end,” and similar expressions used herein are for illustrative purposes only, and the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0030] This utility model application relates to a saliva testing pen. Please refer to [link / reference]. Figures 1-6 The device includes a housing 1, a sample suction element 2, a detection strip 3, and a cap 4. The housing 1 includes a first retainer 11 and a second retainer 12, each with at least one display window 13 and a positioning element 14. The detection strip 3 includes a sample pad 31, a conjugate pad 32, a reaction pad 33, an absorbent pad 34, and a base 35. The reaction pad 33 includes a control line 331 and a detection line 332. The detection strip 3 is placed inside the positioning element 14, with the control line 331 and the detection line 332 of the reaction pad 33 exposed in the display window 13. The sample suction element 2 is located at one end of the housing 1 near the sample pad 31. It is near the end of the shell cap. When the suction element 2 absorbs the sample to be tested, because the suction element 2 is in physical contact with the sample pad 31, the sample will be precipitated onto the sample pad 31, and even onto the entire test strip 3, so that the display window 13 of the double-sided cassette displays the test results of multiple test strips 3. Specifically, the first cassette 11 is provided with two display windows 13, and the inner surface of the first cassette 11 is provided with two positioning elements 14. The second cassette 12 is provided with two display windows 13, and the inner surface of the second cassette 12 is provided with two positioning elements 14. The four test strips 3 are fixed to the four positioning elements 14 respectively, and four indicators can be detected.

[0031] One of the first retaining shell 11 and the second retaining shell 12 is provided with a locking claw 15, and the other of the first retaining shell 11 and the second retaining shell 12 is provided with a locking buckle 16. Specifically, the first retaining shell 11 is provided with three appropriately distributed locking claws 15, and the second retaining shell 12 is provided with locking buckles 16 symmetrically distributed with the locking claws 15. The locking claws 15 protrude from the edge of the side of the first retaining shell 11, where the side refers to the two longer sides of the retaining shell 1. The locking claw 15 includes a locking part 151 and a claw part 152. The locking part 151 extends upward along the side, and the claw part is perpendicular to or approximately perpendicular to the locking part 151. The locking buckle 16 is recessed into the edge of the side of the second retaining shell 12, where the side refers to the two longer sides of the retaining shell 1. The locking buckle 16 includes a relief part 161 and a buckle part 162. 62. The buckle 132 is further recessed into the housing based on the recess of the relief part 161. When the first retainer 11 and the second retainer 12 are engaged, the retaining part 151 and the relief part 161 are tightly fitted together, and the claw part 152 extends into the buckle 161. The first retainer 11 and the second retainer 12 have mutual forces in the horizontal and vertical directions, so that the first retainer 11 and the second retainer 12 form retainer 1 very tightly. Through the engagement of the buckle 16 and the claw 15, the first retainer 11 and the second retainer 12 do not need to be aligned very precisely, and the positioning is easier when engaging. The engagement of the buckle 16 and the claw 15 is tighter, which facilitates the assembly of the production process, improves the production efficiency of the product, and saves the product cost.

[0032] Positioning component 14 includes a positioning groove 141 and a positioning stop 142. A groove on the inner surface of the housing 1 forms the positioning groove 141, and a window 13 is opened within the groove to form a display window. A detection strip 3 is placed within the groove. Each edge of the positioning groove 141 protrudes upwards and extends horizontally inwards to form at least one positioning stop 142. "Inner side" refers to the direction in which the detection strip 3 is placed within the groove, and "horizontal" refers to the direction parallel to the detection strip. The positioning stop 142 can be a cuboid, cube, cylinder, or other cubic shape. Preferably, the positioning stop 142 is a cuboid, forming a cross shape with the groove edge, and its outer edge is arc-shaped. The arc shape can reduce... This reduces the risk of damage to the test strip 3 when it passes through the gap of the positioning stop 142; the distance between the positioning stops 142 on two adjacent groove edges on the same horizontal plane is less than the width of the test strip 3 and greater than the thickness of the test strip 3, which facilitates the test strip 3 to be smoothly inserted into the positioning groove 141 vertically or at an angle, and ensures that the test strips on the first retainer 11 and the second retainer 12 will not fall out of the positioning groove 141, reducing the risk of the test strip 3 leaving the positioning groove 141 and reducing the probability of the test strip 3 contacting the test strip 3 on the other retainer; preferably, the first retainer 11 is provided with positioning stops 142 on the groove edge near the sample pad 31, and the second retainer 12 is near the absorbent pad 3. Positioning stops 142 are provided on the groove edges of the first retainer 11 near the sample pad 31 and the absorbent pad 34, while the second retainer does not have positioning stops 142; or positioning stops 142 are provided on the groove edges of the second retainer 12 near the sample pad 31 and the absorbent pad 34, while the first retainer 11 does not have positioning stops 142. This reduces the number of positioning stops 142, eliminates the complex partition design, and achieves the function of isolating the test strips from each other. Alternatively, positioning stops 142 can be provided on the corresponding groove edges of the first retainer 11 and the second retainer 12, which provides better spatial spacing for the test strips 3. The positioning element 14 also includes a positioning baffle 143 that abuts against the absorbent pad 34 of the detection strip 3. Specifically, the positioning baffle 143 is located in the upper part of the positioning groove 141 near the absorbent pad 34. The positioning baffle 143 is a plane and perpendicular to the adjacent groove edge. It is a closed plane that contacts the positioning groove 141, which can reduce the risk of the detection strip 3 leaving the positioning groove 141 and reduce the probability of the detection strip contacting the detection strip 3 on another housing. The number of positioning baffles 143 can be one or more. Preferably, the thickness of the positioning baffle 143 is the same as the thickness of the positioning baffle 142, and it is only set on the first housing 11 or the second housing 12.

[0033] The sample suction element 2 is located at the end where the housing 1 mates with the cap 4. At least one set of sample suction element baffles 17 are provided on both sides of the first retainer 11 and / or the second retainer near the cap 4, i.e., on both sides that contact the distal end of the sample suction element 2. The distal end refers to the end away from the sample suction element 2 that directly contacts the sample, and the proximal end refers to the end close to the sample suction element 2 that directly contacts the sample. The sample suction element baffles 17 can be cuboids, cubes, cylinders, etc., as long as they satisfy the limiting and fixing of the sample suction element 2. There can be one or more sample suction element baffles 17. Preferably, the gap between at least one set of sample suction element baffles 17 is smaller than the width of the sample suction element 2 and larger than the width of the positioning groove 141, so that the detection strip 3 can extend out of the positioning groove 141 and contact the sample suction element 2. Specifically, the sample suction element baffles 17... 7. The sample absorber ribs 17 are arranged from the far end to the near end along the first retainer 11. When there are 3 sample absorber baffles 17 on each side of the first retainer 11, the two slightly longer baffles 17 are arranged on both sides near the far end of the sample absorber 2, and the distance between the two baffles 17 is less than the width of the sample absorber 2 and greater than the width of the two positioning grooves 141. The four slightly shorter baffles 17 are arranged in groups on both sides of the middle and near end of the sample absorber 2, and the distance between the two baffles 17 is greater than or equal to the width of the sample absorber 2. Positioning posts 19 can be provided on the first retainer 11 and / or the second retainer 12, and positioning holes can be provided on the sample absorber 2. When the first retainer 11 and the second retainer 12 are engaged, the positioning posts 19 are engaged in the positioning holes, which can assist in the positioning and fixing of the sample absorber 2.

[0034] The function of the suction device 2 is to collect saliva in the mouth and guide the saliva onto the test strip 3. When the suction device 2 is a solid suction rod 21, the outer side of the suction rod 21 contacts the suction pad 31 of the test strip 3. The conventional test strip 3 cannot be used by simply placing it directly into the positioning piece 14 in either the forward or reverse direction. It is necessary to make the corresponding bottom card 35 of the test strip 3 transparent and place it into the positioning piece 14 in the forward direction, or extend the sample pad 31 of the conventional test strip 3 and place it into the positioning piece 14 in the reverse direction. The test results can be displayed normally. Forward direction means that the bottom card 35 is in direct contact with the inner surface of the card case, and reverse direction means that the bottom card 35 is not in direct contact with the inner surface of the card case. When the suction piece 2 is a hollow suction ring 22, the inner side of the suction ring 22 is in contact with the suction pad 31 of the test strip 3. Since the suction ring 22 is hollow, the conventional test strip 3 can be used by simply placing it directly into the positioning piece 14 in the reverse direction. In order to facilitate the suction ring 22 to fit into the sample pad 31 using its hollow structure, a movable cover plate 18 is provided on the first card case 11 and / or the second card case 12. After the suction ring 22 is fitted into the sample pad 31, the cover plate 18 is then clamped on the outer side of the suction ring (22). The cover plate 18 can be a flip-top type or a snap-on type.
