Description

Technical Field

[0001] This application relates to the field of blood glucose meter technology, and more particularly to an adapter plug and a blood glucose meter. Background Technology

[0002] A blood glucose meter is a medical device used to measure the concentration of glucose in the blood. It is mainly used for daily blood glucose monitoring by diabetic patients, but can also be used for blood glucose screening in healthy individuals.

[0003] Medical blood glucose meters have adapter plugs on both sides for connecting to the trachea, which are used for air intake and air exhaust respectively. The adapter plugs play a connecting role, so the connection between the adapter plugs and the trachea is crucial. Existing adapter plugs fail to effectively secure the trachea, resulting in poor sealing and ineffective blood glucose monitoring. Therefore, a more stable adapter plug is urgently needed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide an adapter plug and a blood glucose meter, which aims to solve the problem that the existing adapter plug cannot be securely connected to the trachea and may fall off during use.

[0005] The technical solution adopted by this application to solve the technical problem is as follows: an adapter plug, comprising: The adapter plug body has a first air port and a second air port, which are connected to each other through an air guide channel inside the adapter plug body. The upper and lower sides of the adapter plug body are provided with gripping parts for grasping. A first pipe is disposed on the adapter plug body and connected to the first air port. A limiting groove is formed on the outer side wall of the first pipe, and the limiting groove is disposed on the side close to the adapter plug body. The second pipe is disposed on the body of the adapter plug and is connected to the second air port.

[0006] Furthermore, along the length of the first pipe, the diameter of the first pipe gradually decreases.

[0007] Furthermore, the adapter body includes: The motherboard, wherein the air channel is formed inside the motherboard; A pair of side plates, the two side plates being arranged parallel to each other on both sides of the motherboard and connected to the motherboard; Multiple reinforcing plates are staggered on the main board and located between the two side plates.

[0008] Furthermore, the outer contour of the side plate is elliptical.

[0009] Furthermore, the gripping part is disposed on the top of the reinforcing plate.

[0010] Furthermore, the top diameter of the second pipe is smaller than the bottom diameter of the second pipe.

[0011] Furthermore, the adapter plug body is also provided with a protruding sealing part and a sealing ring. The sealing part is arranged around the second air port, and a sealing groove is provided in the middle of the sealing part. The second pipe is arranged in the middle of the sealing groove, and the sealing ring is sleeved on the outside of the second pipe and arranged in the sealing groove.

[0012] Furthermore, the air guiding channel includes a first channel and a second channel arranged vertically, the first channel being connected to the first air port, and the second channel being connected to the second air port.

[0013] Optionally, the adapter plug is integrally molded.

[0014] Another technical solution adopted by this application to solve the technical problem is as follows: a blood glucose meter, including the adapter plug as described above.

[0015] Compared with existing technologies, the adapter plug proposed in this application reduces leakage points during the forming of the air guide channel and improves the airtightness of the air guide channel by setting an air guide channel inside the adapter plug body and a first air port and a second air port connected to it. The first pipe and the second pipe are respectively connected to the first air port and the second air port, which facilitates the connection between the blood glucose meter device and the air tube. A limiting groove is formed on the outer wall of the first pipe, which is located on the side close to the adapter plug body. When the air tube is fitted onto the first pipe, the end of the air tube will contract due to the elasticity of the air tube after reaching the limiting groove, thus more firmly connecting to the adapter plug and preventing the air tube from falling off during use. The grip provided on the adapter plug body makes it easy for users to remove the adapter plug from the device, further improving the user experience. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Medical blood glucose meters typically have two adapter plugs, one on each side. In older designs, the thinner end connects to the internal sealing ring and air tube, while the thicker end connects to the external air tube. One adapter plug is for air intake, and the other for air exhaust. The intake tube guides the blood sample into the testing area, drawing it into the test strip through capillary action. This ensures the blood flows evenly and stably to the reaction zone, controlling the flow rate to prevent it from being too fast or too slow, which could affect the measurement results. The exhaust tube expels gases generated during the test, preventing air bubbles from interfering with measurement accuracy and maintaining a suitable pressure environment in the testing area. In some models, the exhaust tube also controls the point where blood flow stops, ensuring that gases produced by chemical substances during the reaction are expelled promptly. The adapter plugs act as a connector; if the tube and adapter plug are not effectively connected, it will affect usability. Currently, the adapter plugs are connected to the air tube during use. The air tube can easily become loose due to user movement, leading to gas leakage and interfering with the test results.

[0022] In this regard, such as Figures 1 to 4 As shown, this application proposes an adapter plug, including an adapter plug body 10, a first pipe 20, and a second pipe 30. The adapter plug body 10 is provided with a first air port 11 and a second air port 12, which are interconnected through an air guide channel within the adapter plug body 10. The adapter plug body 10 has gripping portions 16 on both its upper and lower sides. The first pipe 20 is disposed on the adapter plug body 10 and communicates with the first air port 11. A circumferential limiting groove 21 is formed on the outer wall of the first pipe 20, and the limiting groove 21 is located on the side closest to the adapter plug body 10. The second pipe 30 is disposed on the adapter plug body 10 and communicates with the second air port 12. The adapter plug body 10 is inserted into the left or right side of a blood glucose meter via the second pipe 30. The air tube is elastically connected to the first pipe 20, and the airflow is controlled by the air pump inside the blood glucose meter to flow in or out through the air guide channel within the adapter plug body 10. Specifically, the limiting groove 21 on the outer side of the first pipe 20 contracts inward, so that the end of the air tube will tighten due to elasticity after reaching the limiting groove 21, thereby preventing the air tube from falling off during use.

[0023] Among them, such as Figure 6 As shown, the adapter plug body 10 has flat grip portions 16 on its upper and lower sides. Specifically, the upper and lower sides have inwardly concave arc surfaces to facilitate gripping with fingers, allowing users to more smoothly pull the adapter plug out of the blood glucose meter. In some embodiments, the grip portions 16 are flat.

[0024] In some embodiments, the diameter of the first pipe 20 gradually decreases along its length. The diameter of the middle part of the first pipe 20 is larger than the diameter of the end of the first pipe 20, meaning that after the air tube enters from the end with the smaller diameter, it is gradually stretched by the increasing diameter, so that the air tube and the adapter terminal are tightly connected to prevent gas leakage.

[0025] In some embodiments, the adapter plug body 10 includes a main board 13, a pair of side plates 14, and a plurality of reinforcing plates 15; the main board 13 forms the air guide channel inside; the two side plates 14 are arranged parallel to each other on both sides of the main board 13 and connected to the main board 13; the plurality of reinforcing plates 15 are staggered on the main board 13 and located between the two side plates 14. The main board 13 is horizontally arranged, the two side plates 14 are vertically and parallelly connected to both sides of the main board 13, and the plurality of reinforcing plates 15 are staggered in a grid pattern on the main board 13. For example, Figure 6 As shown, the top of the reinforcing plate 15 is recessed inward to form a curved grip portion 16. The grip portion 16 is formed by interlaced reinforcing plates 15.

[0026] In this embodiment, the outer contour of the side plate 14 is elliptical. This makes the adapter plug flatter, reduces its size, and improves the portability of the device.

[0027] In some embodiments, the top diameter of the second pipe 30 is smaller than the bottom diameter of the second pipe 30. Specifically, the second pipe 30 includes an end portion and a main body portion, the end portion being frustum-shaped with a gradually decreasing diameter, while the diameter of the main body portion remains constant.

[0028] In some embodiments, the adapter plug body 10 is further provided with a protruding sealing portion 31 and a sealing ring 32. The sealing portion 31 is arranged around the second air port 12, and a sealing groove is provided in the middle of the sealing portion 31. The second pipe 30 is disposed in the middle of the sealing groove, and the sealing ring 32 is sleeved on the outside of the second pipe 30 and disposed in the sealing groove. By providing the sealing ring 32, the risk of gas leakage when passing through the blood glucose meter and the adapter plug can be further reduced, ensuring the gas delivery effect.

[0029] Some of these implementations, such as Figure 5As shown, the air guiding channel includes a vertically arranged first channel 17 and a second channel 18. The first channel 17 is connected to the first air port 11, and the second channel 18 is connected to the second air port 12. The connection between the first channel 17 and the second channel 18 is arc-shaped or cross-shaped. It can be understood that the correspondingly connected first pipe 20 and second pipe 30 are also arranged perpendicularly to each other. When the adapter plug is inserted into the left or right side of the blood glucose meter through the second pipe 30, the first pipe 20 of the adapter plug is parallel to the side of the blood glucose meter, making it convenient for the user to face the blood glucose meter when using it.

[0030] In some embodiments, the adapter plug is integrally molded. The adapter plug body 10, the first pipe 20, and the second pipe 30 are integrally molded using processes such as injection molding and compression molding. This further reduces the risk of air leakage from the adapter plug.

[0031] like Figure 7 As shown in the figure, this application also proposes a blood glucose meter, including the adapter plug as described above. The adapter plug proposed in this application reduces leakage points during the forming of the air guide channel and improves its airtightness by providing an air guide channel inside the adapter plug body and connecting it to a first air port and a second air port. The first and second pipes are respectively connected to the first and second air ports, facilitating connection between the blood glucose meter device and the air tube. A surrounding limiting groove is formed on the outer wall of the first pipe, located near the adapter plug body. When the air tube is fitted onto the first pipe, its end reaches the limiting groove and contracts due to the elasticity of the air tube, thus more firmly connecting to the adapter plug and preventing the air tube from falling off during use. A gripping part provided on the adapter plug body allows the user to easily remove the adapter plug from the device, further improving the user experience.

[0032] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
