Abstract
Description
Technical Field
[0001] This application relates to the field of blood glucose meters, and more specifically, to a sealed and waterproof structure and a blood glucose meter. Background Technology
[0002] A blood glucose meter, also known as a blood glucose meter, is an electronic instrument used to measure blood glucose levels. Blood glucose meters are classified into two types based on their working principle: photoelectric and electrode-based. Electrode-based blood glucose meters have a more scientific testing principle, and the electrodes can be internally mounted.
[0003] For example, a portable blood glucose meter disclosed in Chinese application number 202323060865.0, although protected by a connector box, still exposes the display screen and buttons to the outside. When users wash their hands or cook, water may splash on the meter: blood glucose meters are usually used after finger prick blood sampling, and if hands are wet during operation, the device may come into contact with water droplets; when used outdoors in the rain: when diabetic patients go out for monitoring, they may come into contact with rain due to weather conditions, which may shorten the lifespan of the blood glucose meter or cause the device to malfunction. Utility Model Content
[0004] To overcome the shortcomings of the existing technology, this application provides a sealed and waterproof structure and a blood glucose meter, which can solve the problem of water ingress causing a shortened lifespan or malfunction of the blood glucose meter.
[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is: a sealed and waterproof structure, including waterproof components.
[0006] A waterproof component includes a transparent protective shell, a slot on one side wall of the transparent protective shell, a transparent protective cover connected to one side of the transparent protective shell that can be opened and closed, and the other three sides of the transparent protective cover covering the outside of the transparent protective shell, a U-shaped elastic sealing strip fixedly connected to the three outer sides of the transparent protective shell, and a U-shaped groove that mates with the U-shaped elastic sealing strip on the inner wall of the transparent protective cover.
[0007] In one specific embodiment, the sealed waterproof structure further includes a sealing component disposed inside the socket of the transparent protective shell.
[0008] In one specific implementation, the sealing assembly includes a sealing magnet block that is slidably disposed on the inner bottom wall of the socket, and the inner top wall of the socket is provided with a sealing magnet that cooperates with the sealing magnet block.
[0009] In one specific implementation, the sealing magnet block includes a first sealing gasket, which is slidably connected to the inner bottom wall of the socket, and a magnet block is disposed inside the first sealing gasket.
[0010] In one specific implementation, the sealing magnet component includes a second sealing gasket disposed on the inner top wall of the socket, and a magnet that cooperates with the magnet block is disposed inside the second sealing gasket.
[0011] In one specific implementation, a telescopic spring is provided at the bottom of the first sealing gasket, and the telescopic spring is connected to the inner bottom wall of the socket.
[0012] In one specific implementation, the outer top of the first sealing gasket is arc-shaped.
[0013] On the other hand, the technical solution adopted by the embodiments of this application to solve its technical problem is: a blood glucose meter, including the above-mentioned sealed and waterproof structure and the blood glucose meter body.
[0014] The transparent protective shell and the transparent protective cover are wrapped around the outside of the blood glucose meter body, and the test strip slot of the blood glucose meter body is aligned with the socket.
[0015] The advantages of the embodiments of this application are:
[0016] 1. The transparent protective shell and cover provide a complete waterproof seal for the blood glucose meter, preventing the display and buttons from being exposed.

Detailed Implementation
[0024] The technical solution in this application embodiment is to solve the problem that water ingress into the equipment causes a shortened lifespan or equipment malfunction. The overall approach is as follows:
[0025] Please see Figures 1-5 A sealed and waterproof structure and a blood glucose meter, including a waterproof component 10.
[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The waterproof component 10 includes a transparent protective shell 110. One side wall of the transparent protective shell 110 has an insertion port 111. One side of the transparent protective shell 110 is connected to a transparent protective cover 120 that can be opened and closed. The other three sides of the transparent protective cover 120 cover the outside of the transparent protective shell 110. A U-shaped elastic sealing strip 130 is fixedly connected to the three outer sides of the transparent protective shell 110. The inner wall of the transparent protective cover 120 has a U-shaped groove 140 that mates with the U-shaped elastic sealing strip 130. First, the transparent protective cover 120 is opened. Then, the blood glucose meter body 30 is placed inside the transparent protective shell 110. Next, the transparent protective cover 120 is also placed over the side of the blood glucose meter body 30, so that the transparent protective cover 120 is located outside the transparent protective shell 110. At this point, pressing the transparent protective cover 120 against one side of the transparent protective shell 110 causes the U-shaped elastic sealing strip 130 to engage inside the U-shaped groove 140, thereby achieving a waterproof seal for the blood glucose meter body 30. The transparent protective shell 110 and transparent protective cover 120 provide comprehensive waterproof sealing for the blood glucose meter body 30, preventing the display screen and buttons from being exposed. This protects the meter from water ingress, extending its lifespan and preventing malfunctions, even when used outdoors in rain or with wet hands. Furthermore, the transparent protective shell 110 and cover offer some protection against drops. The U-shaped elastic sealing strip 130 and U-shaped groove 140 further enhance the seal between the transparent cover 120 and the transparent protective shell 110, improving waterproofing. Both the transparent cover 120 and the transparent protective shell 110 are made of flexible materials, such as silicone, allowing the cover 120 to be bent and opened.
[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The sealed and waterproof structure also includes a sealing component 20, which is disposed inside the insertion port 111 of the transparent protective shell 110. The sealing component 20 can seal the insertion port 111 without affecting the insertion test of the test strip.
[0028] In this embodiment, the sealing assembly 20 includes a sealing magnet block 210, which is slidably disposed on the inner bottom wall of the socket 111. The inner top wall of the socket 111 is provided with a sealing magnet 220 that cooperates with the sealing magnet block 210. The sealing magnet block 210 includes a first sealing gasket, which is slidably connected to the inner bottom wall of the socket 111, and a magnet is disposed inside the first sealing gasket. The sealing magnet 220 includes a second sealing gasket, which is disposed on the inner top wall of the socket 111, specifically, the second sealing gasket is embedded in the inner top wall of the socket 111. A magnet that cooperates with the magnet is disposed inside the second sealing gasket. A telescopic spring 230 is disposed at the bottom of the first sealing gasket, and a telescopic groove is formed at the bottom of the socket 111, with the telescopic spring 230 disposed inside the telescopic groove. The telescopic spring 230 is connected to the inner bottom wall of the socket 111. The outer top of the first sealing gasket is arc-shaped. When a blood glucose test strip needs to be inserted into the test strip slot of the blood glucose meter body 30 for blood glucose measurement, the test strip is inserted into the socket 111. It first contacts the arc-shaped part of the first sealing gasket, then inserts between the first and second sealing gaskets and into the slot of the blood glucose meter body 30. At this time, with the cooperation of the magnet and the magnet, the test strip, the first sealing gasket, and the second sealing gasket remain in close contact, forming a seal. This ensures that the blood glucose meter body 30 remains waterproof even during testing. After the test strip is removed, the first and second sealing gaskets, with the cooperation of the magnet and the magnet, form a seal, thus achieving waterproofing. The cooperation of the sealing magnet 210 and the sealing magnet 220 allows for a seal on the socket 111, and this seal remains even during testing.
[0029] Please see Figures 1-5 The technical solution adopted by the embodiments of this application to solve its technical problem is: a blood glucose meter, including a sealed waterproof structure and a blood glucose meter body 30.
[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The transparent protective shell 110 and the transparent protective cover 120 are wrapped around the outside of the blood glucose meter body 30, and the test strip slot of the blood glucose meter body 30 is aligned with the socket 111.
[0031] When this application is used:
[0032] First, open the transparent protective cover 120. Then, place the blood glucose meter body 30 inside the transparent protective shell 110. Next, slip the transparent protective cover 120 over the side of the blood glucose meter body 30, so that the transparent protective cover 120 is outside the transparent protective shell 110. At this point, press the transparent protective cover 120 against one side of the transparent protective shell 110, causing the U-shaped elastic sealing strip 130 to engage inside the U-shaped slot 140, thereby achieving a waterproof seal for the blood glucose meter body 30. The transparent protective shell 110 and the transparent protective cover 120 provide comprehensive waterproof sealing for the blood glucose meter body 30, preventing the display screen and buttons from being exposed. This protects the meter body from water ingress, extending its lifespan and preventing malfunctions, even when used outdoors in rain or when hands are wet. Furthermore, the transparent protective shell 110 also provides protection against drops. The combination of the U-shaped elastic sealing strip 130 and the U-shaped groove 140 improves the sealing between the transparent protective cover 120 and the transparent protective shell 110, thereby enhancing the waterproof effect.
[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
