Description

Technical Field

[0001] The present application relates to the technical field of blood pressure measurement, and in particular to an airbag structure used in a blood pressure measurement device. Background Art

[0002] Blood pressure is one of the important indicators of human physiological health. In the prevention and treatment of cardiovascular diseases, the prevention and treatment of hypertension is of paramount importance. Due to the fast pace of modern life, young people are under great pressure, do not like to exercise, and pay little attention to health. In recent years, hypertension has gradually shown a trend of becoming younger. In contrast to the large number of patients, there is a low awareness rate of hypertension. Therefore, increasing the awareness rate of hypertension and strictly controlling blood pressure are of great significance to improving the quality of life and prolonging life.

[0003] The airbag of traditional wristwatch-style blood pressure measurement is mainly made of materials such as TPU and TPE. The head of the airbag is sealed with the host through the air nozzle, and the radial seal is made by O-ring or other types of elastomers. The air nozzle usually needs to extend into the host space, which occupies more host space and affects the size of the whole device. At the same time, because the air nozzle needs to be on the airbag, it is usually made of the same soft material as the bag body. Affected by the deformation and dimensional tolerance of the material, the precision requirement is very high to ensure the sealing. Utility Model Content

[0004] Based on this, it is necessary to provide an airbag structure for a blood pressure measuring device to address the problem that the traditional airbag needs to be equipped with an air nozzle, which makes the overall volume of the main unit larger and has high precision requirements such as the air nozzle size.

[0006] The airbag body is arranged in a long strip shape, the interior of the airbag body is arranged hollow, and a first airflow channel is arranged at one end of the airbag body;

[0007] A support assembly, disposed near the first airflow channel, the support assembly being fixedly connected to the airbag body;

[0008] The support assembly comprises:

[0009] A first support member, fixedly connected to the airbag body;

[0010] The second support member is fixedly connected to the airbag body, and the first support member and the second support member cooperate to support the airbag body.

[0011] The present application relates to an airbag structure for a blood pressure measuring device, in which a support assembly is provided at a first airflow channel on an airbag body to enhance the support strength and sealing of the airbag body at the first airflow channel, thereby facilitating the connection of the airbag body, and the support assembly comprises a first support member and a second support member, both of which are provided at the first airflow channel, and both of which are fixedly connected to the airbag body, and the first support member, the second support member and the support assembly are coordinated based on the positions and structural relationships of the first support member, the second support member and the support assembly so that the first airflow channel of the airbag body has stable sealing and support.

A first ventilation groove 15 is also provided on the second support member 122. The first ventilation groove 15 is connected to the second air flow channel 14.

[0037] Specifically, the second air flow channel 14 can be a structure that runs through the entire second support member 122, or a structure with a certain depth on the second support member 122; and the first ventilation groove 15 is a groove body that runs through the outer surface of the second support member 122, and the first ventilation groove 15 is connected to the second air flow channel 14.

[0038] In this embodiment, by passing the gas into the second air flow channel 14, the gas flows back through the second air flow channel 14 to the first ventilation groove 15 and finally enters the interior of the airbag body 11. The structure has good sealing performance and good gas flow smoothness.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment of the present application, the airbag body 11 includes a first film 111 and a second film 112 .

[0040] The second film 112 has the same structure as the first film 111. The edge of the first film 111 is sealed and connected to the edge of the second film 112.

[0041] In this embodiment, the first film 111 and the second film 112 are connected into an integrated structure through an edge lamination process.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment of the present application, the first support member 121 is fixedly connected to the first film 111 , and the second support member 122 is fixedly connected to the second film 112 .

[0043] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the first air flow channel 13 is opened on the second film 112. The first air flow channel 13 is connected to the second air flow channel 14.

[0044] Specifically, the second air flow channel 14 opened on the second support member 122 is connected to the first air flow channel 13 opened on the second film 112, and the second support member 122 and the second film 112 are sealed and fixed by screen printing glue, dispensing glue or double-sided tape.

[0045] In this embodiment, the second support member 122 needs to be fixed to the second film 112 before the first film 111 and the second film 112 are pressed together, and the first support member 121 needs to be fixed to the first film 111 after the first film 111 and the second film 112 are pressed together.

[0046] like Figure 6 As shown, in one embodiment of the present application, the first support member 121 is disposed on one side of the airbag body 11. The first support member 121 is fixedly connected to the airbag body 11. The second support member 122 is disposed on the other side of the airbag body 11. The second support member 122 is fixedly connected to the airbag body 11.

[0047] Specifically, the first support member 121 and the second support member 122 are both disposed outside the airbag body 11 .

[0048] In this embodiment, the airbag body 11 is supported by the first support member 121 fixedly connected to one end surface of the airbag body 11 and the second support member 122 fixedly connected to the other end surface of the airbag body 11 .

[0049] like Figure 8 As shown, in one embodiment of the present application, the first support member 121 is fixedly connected to the second support member 122 .

[0050] like Figure 7 As shown, in one embodiment of the present application, the airbag body 11 includes a first film 111 and a second film 112 .

[0051] The second film 112 has the same structure as the first film 111. The edge of the first film 111 is sealed and connected to the edge of the second film 112.

[0052] The first air flow channel 13 is formed on the second film 112 . A third air flow channel 16 is formed on the second support member 122 . The third air flow channel 16 is in communication with the first air flow channel 13 .

[0053] In this embodiment, the third air flow channel 16 opened on the second support member 122 is connected to the first air flow channel 13 on the second film 112 so that the gas flows through the first air flow channel 13 through the third air flow channel 16 and then enters the interior of the airbag body 11.

[0054] like Fig. 9 As shown, in one embodiment of the present application, a first matching groove 17 is formed on the second support member 122. The first matching groove 17 is arranged corresponding to the third air flow channel 16.

[0055] Specifically, the first matching groove 17 , the third air flow channel 16 and the first air flow channel 13 are arranged correspondingly.

[0056] In this embodiment, when the airflow passes through the third airflow channel 16 and flows through the first airflow channel 13 into the interior of the airbag body 11, due to the existence of the first matching groove 17, the first film 111 will be deformed due to the pressure of the airflow, and the airflow will flow more smoothly at the position where it enters the interior of the airbag body 11 from the first airflow channel 13.
