Description

Technical Field

[0001] This application relates to the technical field of blood pressure measurement devices, and particularly to a blood pressure measurement device. Background Art

[0002] When blood flows in blood vessels, the lateral pressure on the vessel wall is called blood pressure. Blood pressure usually refers to arterial blood pressure or systemic blood pressure, which is an important vital sign. Blood pressure measurement is the main means to evaluate blood pressure levels, diagnose hypertension, and observe the efficacy of antihypertensive treatment. Accurately measuring blood pressure is the basis for grass-roots hypertension management. The organic combination of different blood pressure measurement methods is an important factor in improving the diagnosis and management of hypertension.

[0003] The existing watch-type blood pressure measurement device adopts the following scheme: Its main body scheme is similar to that of a consumer-grade watch, but a blood pressure measurement module is added: A piezoelectric pump (which pumps air into the airbag when working), a pump bracket (fixes the pump and forms an air passage leading to the position connecting the airbag, usually two upper and lower brackets), and a barometric pressure sensor are also added inside the main body. In addition, an airbag that surrounds the wrist and is fixed to the watch body and a watch band with a high elastic modulus are provided.

[0004] Since the blood pressure measurement module is integrated in a space similar to that of a consumer-grade watch, a common piezoelectric pump, a pump bracket, and a barometric pressure sensor are added inside its main body, which increases the overall size of the main body, or the overall size of the main body can only be reduced by sacrificing the battery capacity, etc. Summary of the Utility Model

[0005] Based on this, in view of the problem that adding a common piezoelectric pump, a pump bracket, and a barometric pressure sensor inside the traditional main body increases the overall size of the main body, it is necessary to provide a blood pressure measurement device.

[0006] This application provides a blood pressure measurement device, including:

[0007] A main body case;

[0008] A PCB board, fixedly arranged inside the main body case;

[0009] An air pump, arranged inside the main body case, and the air pump is fixedly connected to the PCB board;

[0010] An airbag main body, fixedly connected to the main body case;

[0011] An air passage member, fixedly connected to the PCB board, and the air passage member and the PCB board form a sealed passage for gas flow. One end of the sealed passage is communicated with the air pump, and the other end of the sealed passage is communicated with the airbag main body;

[0012] The airbag main body is communicated with the air pump through the main body case and the air passage member in sequence.

[0013] The present application relates to a blood pressure measuring device. An air passage member is hermetically connected to a PCB board to form a sealed passage through which gas can flow. An air pump is connected to one end of the sealed passage, and an airbag body is connected to the other end of the sealed passage. Thus, when the air pump is started, gas can enter the interior of the airbag body through the sealed passage, or gas can be discharged from the interior of the airbag body through the sealed passage, thereby controlling the gas to enter and exit the interior of the airbag body. This assembly method can save space and has a simple assembly process, so that the overall volume of the main housing can be reduced. Description of the Drawings

[0031] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the blood pressure measurement device includes a main housing 11, a PCB board 12, an air pump 13, an airbag main body 14 and an air passage component 15.

[0033] The PCB board 12 is fixedly arranged inside the main housing 11.

[0034] The air pump 13 is arranged inside the main housing 11. The air pump 13 is fixedly connected to the PCB board 12.

[0035] The airbag main body 14 is fixedly connected to the main housing 11.

[0036] The air passage component 15 is fixedly connected to the PCB board 12. The air passage component 15 and the PCB board 12 form a sealing channel 16 for gas flow. One end of the sealing channel 16 is communicated with the air pump 13. The other end of the sealing channel 16 is communicated with the airbag main body 14.

[0037] The airbag main body 14 is communicated with the air pump 13 through the main housing 11 and the air passage component 15 in sequence.

[0038] Specifically, the PCB board 12 is fixedly connected to the main housing 11 by bolts, or the PCB board 12 is fixedly connected to the main housing 11 by a buckle; the air pump 13 is an integrated circuit piezoelectric pump, and the air pump 13 is directly fixedly connected to the PCB board 12, and the PCB board 12 is electrically connected to the air pump 13.

[0039] In this embodiment, the air duct member 15 is hermetically connected to the PCB board 12 to form a sealed channel 16 through which gas can flow. One end of the air pump 13 communicates with the sealed channel 16, and the other end of the airbag main body 14 communicates with the sealed channel 16. Then, when the air pump 13 is started, gas can enter the interior of the airbag main body 14 through the sealed channel 16, or gas can be discharged from the interior of the airbag main body 14 through the sealed channel 16, thereby controlling the entry and exit of gas into and out of the interior of the airbag main body 14. This assembly method can save space and the assembly process is simple, so that the overall volume of the main housing 11 is reduced.

[0040] As Figure 5 shown, in an embodiment of the present application, a first air duct 121 is provided on the PCB board 12. The air pump 13 is disposed on one side of the PCB board 12. The air duct member 15 is disposed on the other side of the PCB board 12. The air pump 13 communicates with the air duct member 15 through the first air duct 121.

[0041] Specifically, the air duct member 15 and the air pump 13 are respectively disposed on both sides of the PCB board 12, and a communication is formed between the air duct member 15 and the air pump 13 through the first air duct 121 provided on the PCB board 12.

[0042] In this embodiment, by providing the first air duct 121 on the PCB board 12 to connect the air duct member 15 and the air pump 13, the overall volume of the connection between the air pump 13 and the air duct member 15 is significantly reduced, so as to create more space for the main housing 11, or reduce the overall volume of the main housing 11.

[0043] As Figure 6 shown, in an embodiment of the present application, a pressure sensor 17 is fixed in the sealed channel 16.

[0044] In this embodiment, by providing the pressure sensor 17 in the sealed channel 16, the pressure of the gas can be detected in real time, and since the air duct member 15 is made of a hard material, it is convenient for the installation and detection of the pressure sensor 17.

[0045] As Figure 3 and Figure 4 shown, in an embodiment of the present application, the main housing 11 includes a first housing 111 and a second housing 112.

[0046] The second housing 112 is disposed at the bottom of the first housing 111. The second housing 112 is fixedly connected to the first housing 111. A second air passage 112a is formed in the second housing 112.

[0047] The airbag body 14 is fixedly connected to the second housing 112. The airbag body 14 communicates with the second air passage 112a. The airway member 15 communicates with the second air passage 112a.

[0048] Specifically, the first housing 111 and the second housing 112 are integrally connected by bolts or buckles. The airbag body 14 is fixedly connected to the second housing 112. The airbag body 14 communicates with the sealing passage 16 through the second air passage 112a formed in the second housing 112.

[0049] In this embodiment, the second air passage 112a formed in the second housing 112 is used as an intermediate passage to connect the airbag body 14 and the sealing passage 16, so that gas can enter and exit the interior of the airbag body 14 through the second air passage 112a. And this structure directly uses the housing as the gas passage, which further saves the overall occupied space.

[0050] As Figure 7 shown, in an embodiment of the present application, a first groove 112b is formed in the second housing 112. The first groove 112b is disposed on a side of the second air passage 112a close to the airway member 15.

[0051] A first seal 18 is disposed in the first groove 112b. The first seal 18 is sleeved outside the second air passage 112a. One end of the first seal 18 abuts against the second housing 112. The other end of the first seal 18 abuts against the airway member 15.

[0052] Specifically, the first groove 112b is set as a continuous groove, and the first groove 112b surrounds the second air passage 112a. The first groove 112b can be set as a circular ring or an ellipse. And a first seal 18 matching the shape of the first groove 112b is disposed in the first groove 112b. The first seal 18 is made of rubber.

[0053] In this embodiment, by placing the first seal 18 in the first groove 112b, and then through the pressing between the first housing 111 and the second housing 112, the first seal 18 is squeezed, so as to perform a circumferential seal on the connection between the airway member 15 and the second air passage 112a.

[0054] As Figure 4As shown, in an embodiment of the present application, a second groove 112c and a third groove 112d are further formed in the second housing 112. Both the second groove 112c and the third groove 112d are arranged in an annular shape. Both the second groove 112c and the third groove 112d are disposed on the side of the second housing 112 close to the airbag main body 14. The axis of the second groove 112c is collinear with the axis of the third groove 112d. The diameter of the third groove 112d is larger than the diameter of the second groove 112c. The second groove 112c is sleeved on the outer side of the second air passage 112a.

[0055] A second seal 19 is provided in the second groove 112c. A third seal 20 is provided in the third groove 112d. One end of the second seal 19 abuts against the second housing 112. The other end of the second seal 19 abuts against the airbag main body 14. One end of the third seal 20 abuts against the second housing 112. The other end of the third seal 20 abuts against the airbag main body 14.

[0056] Specifically, both the second groove 112c and the third groove 112d are provided at the connection between the second housing 112 and the airbag main body 14, and both the second groove 112c and the third groove 112d are arranged in an annular shape. The circular diameter of the third groove 112d is larger than the circular diameter of the second groove 112c. The second groove 112c is arranged around the second air passage 112a.

[0057] In this embodiment, when the second seal 19 is placed in the second groove 112c and the third seal 20 is placed in the third groove 112d, the second seal 19 and the third seal 20 will be squeezed when the first housing 111 and the second housing 112 are connected, thereby sealing the connection between the airbag main body 14 and the second air passage 112a.

[0058] As Figure 8 shown, in an embodiment of the present application, the airbag main body 14 includes an airbag member 141 and an adapter member 142.

[0059] The interior of the airbag member 141 is hollow.

[0060] The adapter member 142 is disposed at the end of the airbag member 141. The adapter member 142 is in communication with the interior of the airbag member 141. The adapter member 142 is fixedly connected to the second housing 112. The airbag member 141 is in communication with the second air passage 112a through the adapter member 142.

[0061] In this embodiment, the adapter 142 is used to fix and support the airbag 141. The airbag 141 communicates with the adapter 142 and is connected to the second air passage 112a in the second housing 112 through the adapter 142, thereby forming a complete passage for the gas to flow into the interior of the airbag 141.

[0062] As Figure 9 shown, in an embodiment of the present application, the PCB board 12 includes a first board 122 and a second board 123.

[0063] The first board 122 is disposed inside the main housing 11. The first board 122 is fixedly connected to the main housing 11.

[0064] The second board 123 is fixedly connected to the first board 122. The first board 122 is electrically connected to the second board 123. The air pump 13 is fixedly connected to the second board 123.

[0065] In this embodiment, to further reduce the space occupied by the connection between the air pump 13 and the PCB board 12, the space is effectively utilized by reducing the stacking.

[0066] As Figure 10 shown, in an embodiment of the present application, a third air passage 123a is formed on the second board 123. The third air passage 123a communicates with the air pump 13. The air passage member 15 communicates with the air pump 13 through the third air passage 123a.

[0067] In this embodiment, the air pump 13 communicates with the air passage member 15 by communicating with the third air passage 123a formed on the second board 123.

[0068] As Figure 10 shown, in an embodiment of the present application, a fourth groove 112e is formed on the first board 122. The air pump 13 is disposed inside the fourth groove 112e.

[0069] In this embodiment, by forming the fourth groove 112e on the first board 122 and placing the air pump 13 inside the fourth groove 112e, the overall thickness occupied space is reduced by reducing the stacking.

[0070] The technical features of the above-described embodiments can be combined arbitrarily, and there is no limitation on the execution order of the method steps. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
