Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly relates to a device for measuring blood pressure. Background Art

[0002] With the improvement of people's living standards, health has become the focus of everyone's attention. Now, more or less, every family will prepare some detection tools for their physical health conditions. A sphygmomanometer is one of the more common products. Because of its simple operation, convenient use, and appropriate size, consumers can measure their own blood pressure at home.

[0003] However, due to its unreasonable layout, the existing sphygmomanometers have large space occupied by each internal component, low space utilization rate, and thus large volume; the unreasonable layout also increases the costs of consumables such as cables, air pipes, and the housing. For example, the sphygmomanometers disclosed in Chinese patent documents CN202120862163.6 and CN202021423064.X.

[0004] Upon investigation, by carefully studying the internal structure of the existing sphygmomanometers, two main reasons for the above problems are found:

[0005] 1. In the existing sphygmomanometers, an air pump, a battery, an air release valve, and a four-way valve in the air circuit module are all installed in the housing. After installation, there is a large space between the air circuit module and the panel, resulting in waste, low space utilization rate, and inability to reduce the volume of the sphygmomanometer.

[0006] 2. In the existing sphygmomanometers, the switches of the control module press the buttons in the control unit by sliding up and down. Therefore, the control unit must be located below the switch. The control unit is also located between the air circuit module and the panel. The existence of the control unit further increases the thickness of the sphygmomanometer. Moreover, as long as the control unit is located between the air circuit module and the panel, the thickness of this part cannot be reduced.

[0007] Therefore, if we want to make the layout more reasonable and obtain a sphygmomanometer with a smaller volume and lower cost, we must re-conceive the installation methods of the air circuit module and the control module. Summary of the Invention

[0008] To solve the above technical problems, the present utility model provides a blood pressure measuring device, which includes an integration device and a housing. The integration device includes a panel, a gas circuit module, a control module, and a display screen. The gas circuit module and the control module are both installed on the panel. The housing has no installation function. It only covers each module inside after being connected to the panel, and only serves the functions of enclosure and decoration. Therefore, the size of the housing is reduced, thereby reducing the volume of the sphygmomanometer. The control module includes a control unit and a switch. The control unit and the display screen are installed in the accommodation groove of the panel. The switch is rotatably arranged on the panel. The switch is configured to rotate when the switch is pressed, and the control button is pressed from bottom to top. The rotational movement of the switch is used to replace the up-and-down movement of the switch in the prior art, so that the position of the control unit is no longer restricted to below the switch, enabling the control unit to be installed on the panel together with the display screen, thereby eliminating the adverse effect on the volume of the sphygmomanometer caused by the control unit being clamped between the panel and the gas circuit module, making the thickness of the sphygmomanometer in this solution thinner and the volume smaller. A sensor is also provided on the control unit. The air pump and the air release valve are connected to the battery through the control unit. The four-way valve is respectively connected to the air pump, the air release valve, and the sensor.

[0009] The technical solution of the present utility model is realized as follows:

[0010] A blood pressure measuring device includes an integration device and a housing. The integration device includes a panel, a gas circuit module, a control module, and a display screen. The gas circuit module, the control module, and the display screen are all installed on the panel. The housing is connected to the panel and encloses the gas circuit module and the control module inside the housing. The gas circuit module includes a battery, an air pump, a four-way valve, and an air release valve. A mounting seat is integrally formed on the panel. The battery, the air pump, and the air release valve are all installed on the mounting seat. The four-way valve is integrally formed with the panel. The control module includes a control unit and a switch. A accommodation groove is opened on the panel. The control unit and the display screen are installed in the accommodation groove, and a through window is also opened on the panel at the accommodation groove. The control unit is exposed from the panel toward the inside of the housing at the window. A control button is provided on the control unit. The switch is rotatably arranged on the panel. The switch is configured to rotate when the switch is pressed, and the control button is pressed from bottom to top. A sensor is also provided on the control unit. The air pump and the air release valve are connected to the battery through the control unit. The four-way valve is respectively connected to the air pump, the air release valve, and the sensor.

[0011] First, since the integration device uses the panel as the installation main body and installs the gas path module, the control module, and the display screen on the panel, the housing in this solution no longer has an installation function. It only covers each module inside after being connected to the panel, and only serves the functions of enclosure and decoration. Therefore, the size of the housing only needs to be large enough to accommodate each module. Also, since each module is installed on the panel and is in close contact with the panel, the structure of the integration device is sufficiently compact, and the volume required for the housing will be smaller. Therefore, through the above more reasonable layout method, the redundant gaps existing in the prior art are reduced, and after further reducing the volume of the housing, the volume of the entire sphygmomanometer is greatly reduced.

[0012] Secondly, the rotational movement of the switch is used to replace the up-and-down movement of the switch in the prior art, so that the position of the control unit is no longer restricted to below the switch, and the control unit can be installed on the panel together with the display screen, thereby eliminating the adverse effect on the volume of the sphygmomanometer caused by the control unit being sandwiched between the panel and the gas path module, making the sphygmomanometer in this solution thinner and smaller in volume.

[0013] After reducing the volume of the sphygmomanometer, the benefits that can be brought are to reduce the costs of packaging, transportation, and production. The required packaging volume becomes smaller, and the consumables such as cables and air pipes required also become fewer. Moreover, the sphygmomanometer in this solution is more convenient for production and assembly, which can improve production efficiency. Not only is the four-way valve integrally formed with the panel, and there is no need to install the four-way valve anymore, but also the installation positions of the battery, deflation valve, air pump, switch, control unit, and display screen are more concentrated and all located on the panel. Therefore, the installation is more convenient and fast, and there are fewer places that need to be locked with screws.

[0014] Preferably, a restricting member is clamped on the mounting seat, and the restricting member is configured to lock the air pump, the deflation valve, and the battery on the mounting seat. Using a single restricting member to lock the air pump, the deflation valve, and the battery on the mounting seat, and the restricting member is directly clamped to the mounting seat without screw connection, which simplifies the production and assembly operations.

[0015] Preferably, the restricting member includes locking portions and clamping portions at both ends. The mounting seat is provided with locking hooks and buckles. First card holes are formed on the locking portions, and second card holes are formed on the clamping portions. The clamping portion has elasticity. When installing the restricting member onto the mounting seat, the locking hook first enters the first card hole to be clamped with the locking portion, and then the restricting member is rotated to make the buckle enter the second card hole to be clamped with the clamping portion. The connection between the restricting member and the mounting seat does not require screw locking, and only buckle connection is needed, which further simplifies the production and assembly steps and improves production efficiency.

[0016] Preferably, a first mounting groove, a second mounting groove, and a third mounting groove are successively formed in the mounting base from back to front. The battery is placed in the first mounting groove, the air pump is placed in the second mounting groove, and the air release valve is placed in the third mounting groove. The limiting member is arranged on the mounting base in the front-back direction and limits the battery, the air pump, and the air release valve in the first mounting groove, the second mounting groove, and the third mounting groove respectively. After the battery, the air pump, and the air release valve are placed in the three mounting grooves of the mounting base, the limiting member positions and locks the three of them. The three are fixed in the same area, with a reasonable layout and a compact structure, thereby reducing the space occupied by the air circuit module and making the product volume smaller. The arrangement of the limiting member in the front-back direction can more effectively limit the battery, the air pump, and the air release valve.

[0017] Preferably, the switch includes a pressing part, a rotating part, and an extension arm. The rotating part is rotatably connected to the panel. The pressing part and the extension arm are respectively located on both sides of the rotating part, and the extension arm is located on the side close to the control unit. An avoidance hole is formed in the panel. The pressing part is arranged in the avoidance hole. The end of the extension arm extends below the control button of the control unit. When the pressing part is pressed and rotates downward, the extension arm presses the control button upward. Using the rotation of the switch instead of the up-and-down movement of the switch enables the position of the control unit to no longer be restricted to below the switch, allowing the control unit to be installed on the panel together with the display screen, thereby eliminating the adverse impact of the control unit on the volume of the sphygmomanometer.

[0018] Preferably, a rotating groove is formed in the rotating part, and a rotating shaft is provided on the panel. The rotating groove is clamped on the rotating shaft, and the switch is rotatably arranged on the panel through the rotating groove and the rotating shaft. The rotating groove on the rotating part and the rotating shaft on the panel cooperate with each other to enable the switch to be rotatably arranged on the panel. Using the rotational movement of the switch to replace the straight up-and-down switch movement in the existing sphygmomanometer enables the control unit and the display screen to be installed on the panel together, making the layout of the control unit more reasonable and reducing the thickness of the product.

[0019] Preferably, the opening of the rotating groove is smaller than the diameter of the rotating groove. The smaller opening of the rotating groove can enable the rotating shaft to be clamped into the rotating groove, and the switch is not easily disengaged from the rotating shaft.

[0020] Preferably, the switch further includes an elastic part. One end of the elastic part is connected to the lower end of the pressing part, and the other end is connected to the panel. The elastic part is configured to give the pressing part the ability to rebound. After one end of the elastic part is connected to the panel, it gives the pressing part connected to the other end the ability to rebound. When the pressing part is pressed downward, the elastic part does not affect the rotation of the switch on the panel. When the pressing part is released, the elastic part can drive the pressing part to return to its original position.

[0021] Preferably, the length and width dimensions of the display screen are the same as those of the receiving groove; the display screen and the control unit are stacked and installed in the receiving groove, with the display screen located above the control unit; the control unit is provided with positioning holes, and the display screen is provided with downwardly protruding positioning pins that enter the positioning holes; the display screen is also provided with elastic latches and connecting ears, and the panel is provided with locking holes and connecting grooves beside the receiving groove. When the display screen and the control unit are installed in the receiving groove, the elastic latches are snapped into the locking holes, and the connecting ears enter the connecting grooves and are locked by screws. Since the dimensions of the display screen and the receiving groove are the same, after the control unit and the display screen are mutually positioned by the positioning pins and the positioning holes, the control unit and the display screen will be limited in the front-back and left-right directions; after the elastic latches are snapped into the locking holes, the control unit and the display screen are limited in the up-down direction. After the connecting ears and the connecting grooves are locked by screws, it can effectively prevent the control unit and the display screen from detaching from the panel, making the control unit and the display screen more stably installed on the panel.

[0022] Preferably, the four-way valve includes a main air outlet that is exposed from the housing and is connected to the inflation cuff of the sphygmomanometer; the four-way valve is also connected to an intake air pipe, a rapid air release pipe, a uniform air release pipe, and a signal pipe; the intake air pipe is connected to the air pump, the rapid air release pipe is connected to the air release valve, and the signal pipe is connected to the sensor; when starting to work, the air pump inflates the four-way valve through the intake air pipe, and the main air outlet inflates the inflation cuff; during detection, the uniform air release pipe uniformly releases air from the inflation cuff, and the signal pipe gives the sensor a pressure value; when ending, the air release valve is opened, and the gas in the inflation cuff is released by the air release valve after passing through the rapid air release pipe.

[0023] The design starting point, concept, and beneficial effects of the present utility model adopting the above technical solutions are as follows:

[0024] First of all, since the integration device takes the panel as the installation main body and installs the air circuit module, the control module, and the display screen on the panel, the housing in this solution no longer has an installation function. It only covers each module inside after being connected to the panel and only serves the functions of enclosure and decoration. Therefore, the size of the housing only needs to be large enough to accommodate each module. Also, since each module is installed on the panel and each module is in close contact with the panel, the structure of the integration device is sufficiently compact, and the volume required for the housing will also be smaller; thus, through the above more reasonable layout method, the redundant gaps existing in the prior art are reduced, and after further reducing the volume of the housing, the volume of the entire sphygmomanometer is significantly reduced.

[0025] Secondly, the rotational movement of the switch is used to replace the up-and-down movement of the switch in the prior art, so that the position of the control unit is no longer restricted to below the switch, enabling the control unit to be installed on the panel together with the display screen, thereby eliminating the adverse effect on the volume of the sphygmomanometer caused by the control unit being sandwiched between the panel and the gas path module, making the thickness of the sphygmomanometer in this solution thinner and the volume smaller.

[0026] After reducing the volume of the sphygmomanometer, the benefits that can be brought are to reduce the costs of packaging, transportation and production. The required packaging volume becomes smaller, and the consumables such as cables and air pipes required also become fewer. Moreover, the sphygmomanometer in this solution is more convenient in production and assembly, which can improve production efficiency. Not only is the four-way valve integrally formed with the panel and there is no need to install the four-way valve anymore, but also the installation positions of the battery, deflation valve, air pump, switch, control unit and display screen are more concentrated and all located on the panel. Therefore, the installation is more convenient and fast, and there are fewer places that need to be locked with screws. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0045] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0046] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present utility model is not limited by the specific embodiments disclosed below.

[0047] In the description of the present utility model, the terms "first", "second", "third", etc. are used only for the purpose of description and cannot be construed as indicating or implying relative importance.

[0048] The specific embodiments of the present utility model are as follows:

[0049] As Figure 1 、 3 、5, 14 shown, the present utility model provides a blood pressure measuring device, including an integration device and a housing 1. The integration device includes a panel 2, a gas circuit module, a control module, and a display screen 3. The gas circuit module, the control module, and the display screen 3 are all installed on the panel 2. The housing 1 is connected to the panel 2 and covers the gas circuit module and the control module inside the housing 1. The gas circuit module includes a battery 4, an air pump 5, a four-way valve 6, and a deflation valve 7. An installation seat 8 is integrally formed on the panel 2. The battery 4, the air pump 5, and the deflation valve 7 are all installed on the installation seat 8. The four-way valve 6 is integrally formed with the panel 2. The control module includes a control unit 9 and a switch 10. A receiving groove 11 is formed on the panel 2. The control unit 9 and the display screen 3 are installed in the receiving groove 11. And a through window 12 is also formed on the panel 2 at the position of the receiving groove 11. The control unit 9 is exposed from the panel 2 toward the inside of the housing 1 at the window 12. A control button 13 is provided on the control unit 9. The switch 10 is rotatably arranged on the panel 2. The switch 10 is configured to rotate when the switch 10 is pressed. The switch 10 presses the control button 13 from bottom to top. A sensor 14 is also provided on the control unit 9. The air pump 5 and the deflation valve 7 are connected to the battery 4 through the control unit 9. The four-way valve 6 is respectively connected to the air pump 5, the deflation valve 7, and the sensor 14.

[0050] As Figures 1 - 5 、8, 16, 17 shown, first, since the integration device takes the panel 2 as the installation main body and installs the gas circuit module, the control module, and the display screen 3 on the panel 2, the housing 1 in this solution no longer has an installation function. It only covers each module inside after being connected to the panel 2 and only plays the functions of sealing and decoration. Therefore, the size of the housing 1 only needs to be large enough to accommodate each module. Also, since each module is installed on the panel 2 and each module is in close contact with the panel 2, the structure of the integration device is sufficiently compact, and the volume required for the housing 1 will also be smaller. Therefore, through the above more reasonable layout method, the redundant gaps existing in the prior art are reduced, and after further reducing the volume of the housing 1, the volume of the entire sphygmomanometer is greatly reduced.

[0051] Secondly, the rotational movement of the switch 10 replaces the up-and-down movement of the switch 10 in the prior art, so that the position of the control unit 9 is no longer restricted to be below the switch 10, enabling the control unit 9 to be installed on the panel 2 together with the display screen 3, thereby eliminating the adverse impact on the volume of the sphygmomanometer caused by the control unit 9 being sandwiched between the panel 2 and the gas circuit module, making the thickness of the sphygmomanometer in this solution thinner and the volume smaller.

[0052] After reducing the volume of the sphygmomanometer, the benefits that can be brought are to reduce the costs of packaging, transportation and production. The required packaging volume becomes smaller, and the consumables such as cables and air pipes are reduced. Moreover, the sphygmomanometer in this solution is more convenient in production and assembly, which can improve production efficiency. Not only is the four-way valve 6 integrally formed with the panel 2 without the need to install the four-way valve 6 anymore, but also the installation positions of the battery 4, the deflation valve 7, the air pump 5, the switch 10, the control unit 9 and the display screen 3 are more concentrated and all located on the panel 2. Therefore, the installation is more convenient and fast, and the places that need to be locked with screws are also fewer.

[0053] Specifically, as Figures 5 - 8 shown, the four-way valve 6 includes a main air outlet 15. The main air outlet 15 is exposed on the housing 1, and the main air outlet 15 is connected to the inflation cuff of the sphygmomanometer. An air inlet pipe 16, a rapid deflation pipe 17, a uniform deflation pipe 18 and a signal pipe 19 are also connected to the four-way valve 6. The air inlet pipe 16 is connected to the air pump 5, the rapid deflation pipe 17 is connected to the deflation valve 7, and the signal pipe 19 is connected to the sensor 14. When starting to work, the air pump 5 inflates the four-way valve 6 through the air inlet pipe 16, and the main air outlet 15 inflates the inflation cuff. During detection, the uniform deflation pipe 18 deflates the inflation cuff at a uniform speed, and the signal pipe 19 gives the sensor 14 a pressure value. When it ends, the deflation valve 7 is opened, and the gas in the inflation cuff is discharged by the deflation valve 7 after passing through the rapid deflation pipe 17.

[0054] The battery 4 is a rechargeable battery 4. A charging interface 20 for charging the battery 4 is also provided on the panel 2. The charging interface 20 is fixedly installed on the panel 2 by screws and the charging interface 20 is exposed on the housing 1.

[0055] For the installation of the gas circuit module:

[0056] The panel 2 includes a main body 21 and the mounting base 8. The mounting base 8 protrudes downward on the back of the main body 21. The four-way valve 6 integrally formed with the main body 21 also protrudes downward on the back of the main body 21 and the four-way valve 6 is located beside the mounting base 8, that is, the four-way valve 6 is located beside the air pump 5 and the air release valve 7, which can make the length of the trachea used for connecting the air pump 5, the air release valve 7 and the four-way valve 6 shorter compared with the existing sphygmomanometer, thereby further saving consumables and reducing costs; a reinforcing rib 22 is provided between the four-way valve 6 and the main body 21 to strengthen the connection strength between the four-way valve 6 and the main body 21; the panel 2 and the four-way valve 6 are both plastic parts and are integrally formed by injection molding; compared with the panel 2 of the sphygmomanometer in the prior art, the panel 2 of this sphygmomanometer not only has the function of installing the display screen 3, but also has more functions. It not only integrally forms the mounting base 8 and the four-way valve 6, but also serves as the installation main body of the integrated device, thereby avoiding the problems existing when using the housing 1 as the installation main body.

[0057] The mounting base 8 is successively provided with a first mounting groove 23, a second mounting groove 24 and a third mounting groove 25 from back to front. The battery 4, the air pump 5 and the air release valve 7 are also distributed from back to front in sequence. The battery 4 is placed in the first mounting groove 23, the air pump 5 is placed in the second mounting groove 24, and the air release valve 7 is placed in the third mounting groove 25; further, a limiting part 26 is clamped on the mounting base 8. The limiting part 26 is configured to lock the air pump 5, the air release valve 7 and the battery 4 on the mounting base 8. The limiting part 26 is arranged on the mounting base 8 in the front-back direction. Using a single limiting part 26, the air pump 5, the air release valve 7 and the battery 4 can be locked on the mounting base 8, and the limiting part 26 is directly clamped with the mounting base 8 without screw connection, which simplifies the production and assembly operation; the arrangement of the limiting part 26 in the front-back direction can more effectively limit the battery 4, the air pump 5 and the air release valve 7; the limiting part 26 includes a first limiting groove 27, a second limiting groove 28 and a third limiting groove 29. The first limiting groove 27 avoids the battery 4 and limits the battery 4 in the first mounting groove 23, the second limiting groove 28 avoids the air pump 5 and limits the air pump 5 in the second mounting groove 24, and the third limiting groove 29 avoids the air release valve 7 and limits the air release valve 7 in the third mounting groove 25; after the battery 4, the air pump 5 and the air release valve 7 are placed in the three mounting grooves of the mounting base 8, they are limited and locked by the corresponding three limiting grooves of the limiting part 26, and the three are fixed in the same area, with a reasonable layout and a compact structure, thereby reducing the space occupied by the air circuit module and making the product volume smaller.

[0058] Furthermore, as Figure 6 、 8As shown in FIGS. 12, the limiting member 26 is in the shape of a special-shaped sheet, which includes a locking portion 30 and a clamping portion 31 at both ends. A locking hook 32 and a buckle 33 are provided on the mounting seat 8. A first card hole 34 is provided on the locking portion 30, and a second card hole 35 is provided on the clamping portion 31. The clamping portion 31 has elasticity. When the limiting member 26 is installed on the mounting seat 8, the locking hook 32 first enters the first card hole 34 to be clamped with the locking portion 30, and then the limiting member 26 is rotated to make the buckle 33 enter the second card hole 35 to be clamped with the clamping portion 31. The connection between the limiting member 26 and the mounting seat 8 does not require screw locking, and only the buckle 33 connection is needed, which further simplifies the production and assembly steps and improves the production efficiency.

[0059] As Figure 10 , 11 , FIGS. 13 and 15 show that the switch 10 includes a pressing portion 101, a rotating portion 102 and an extension arm 103. The rotating portion 102 is rotatably connected to the panel 2. The pressing portion 101 and the extension arm 103 are respectively located on both sides of the rotating portion 102, and the extension arm 103 is located on the side close to the control unit 9. An avoidance hole 36 is provided on the panel 2. The pressing portion 101 is arranged in the avoidance hole 36. The end of the extension arm 103 extends below the control button 13 of the control unit 9. When the pressing portion 101 is pressed and rotated downward, the extension arm 103 presses the control button 13 upward. Using the rotation of the switch 10 to replace the up and down movement of the switch 10, the position of the control unit 9 is no longer restricted to below the switch 10, so that the control unit 9 can be installed on the panel 2 together with the display screen 3, thereby eliminating the adverse impact of the control unit 9 on the volume of the sphygmomanometer.

[0060] A rotating groove 37 is provided on the rotating portion 102, and a rotating shaft 38 is provided on the panel 2. The rotating groove 37 is clamped on the rotating shaft 38. The switch 10 is rotatably arranged on the panel 2 through the rotating groove 37 and the rotating shaft 38. The rotating groove 37 on the rotating portion 102 and the rotating shaft 38 on the panel 2 cooperate with each other to realize the rotatable setting of the switch 10 on the panel 2.
