Description

TECHNICAL FIELD

[0001] The utility model belongs to wrist wearable device technical field, concretely relates to a gasbag cover plate structure for fixing sphygmomanometer gasbag. BACKGROUND

[0002] With the vigorous development of social economy and the significant improvement of people's life quality, health has become the focus of public attention. Especially under the background of the increasing global health awareness, people pay more attention to the monitoring and management of their own physical condition. At the same time, the rapid progress of technology also provides people with more convenient and efficient health management tools.

[0003] Under the impetus of this trend, wearable devices with blood pressure monitoring function gradually enter the market and are favored by consumers. Such devices are not only convenient to carry, but also can monitor the blood pressure changes of users in real time and continuously, providing powerful data support for the prevention and control of cardiovascular diseases such as hypertension. Wearable devices with blood pressure monitoring function contain a gasbag connected to a gas pump, which is fixed to the wristband and faces the user's wrist. When measuring blood pressure, the gas pump inflates the gasbag, so that the inflated gasbag exerts pressure on the user's wrist, and the user's wrist exerts a counterforce on the gasbag. The high-precision pressure sensor inside the device can capture the pressure change of the gasbag and convert these pressure signals into electrical signals. Subsequently, through the built-in microprocessor, these electrical signals are analyzed and processed, and finally converted into blood pressure values that we can intuitively understand.

[0004] With the continuous development of wearable devices with blood pressure monitoring function, their functions are also developing, such as motion tracking, sleep monitoring and other intelligent functions. The increase in functions makes the device size continue to increase, and users need to adjust the gasbag according to their own needs during use, such as increasing or decreasing the gasbag, to ensure user comfort. At the same time, users also need to ensure stable blood pressure monitoring during device use, which requires that the connection between the gasbag and the pump in the device be firm and reliable while being able to flexibly increase or decrease the gasbag.

[0005] In the prior art, the fixing methods of the gasbag and the device body of the intelligent blood pressure monitoring watch mainly include the following four types:

[0006] 1. Integrated fixing. In this fixing structure, the gasbag cannot be detached, which cannot meet the user's demand for increasing or decreasing the gasbag;

[0007] 2. No fixing. In this way, the gasbag is easy to fall off, especially in the case of more movement or wrist activity, which will affect the accuracy of blood pressure monitoring;

[0008] 3. Buckle type fixing. In this fixing mode, the air bag can be detached, but in the process of long-term use, the friction between the air bag and the air bag fixing device will cause wear at the connection, thereby increasing the possibility of loosening between the air bag and the fixing device, causing the air bag to be easily detached, and also affecting the overall durability of the equipment, reducing the service life of the equipment;

[0009] 4. Locking assembly fixing. In this fixing mode, the entire locking assembly occupies a large volume and is not light enough, and if it is hit by external force or falls, etc., the locking assembly is easily damaged, thereby causing poor air bag sealing and affecting blood pressure measurement results.

[0010] Patent No. CN115670410A discloses a connection method of an active fixing belt and an equipment body. The fixing belt 2 and the equipment body 1 can be an integral structure. Or the fixing belt 2 and the equipment body 1 are detachable structures, for example, connected by a buckle. Since the fixing belt and the equipment body are an integral structure and cannot be detached, it cannot meet the diversified needs of users. On the other hand, using a buckle connection greatly reduces the durability of the product, and also increases the risk of losing the equipment body.

[0011] Patent No. CN116941867A discloses a locking assembly structure, thereby simplifying the steps of disassembling and assembling the air bag. And increasing the firmness of the air bag being fixed, reducing the risk of the air bag being easily detached. However, the entire locking assembly occupies a large volume and is not light enough, and if it is hit by external force or falls, etc., the locking assembly is easily damaged, thereby causing poor air bag sealing and affecting blood pressure measurement results.
