Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a blood pressure watch. Background Technology

[0002] Existing smart bracelets and smartwatches all incorporate waterproof technology, which involves creating a micro-hole in the casing and sealing it with a waterproof and breathable valve. This allows air to pass through while preventing moisture from entering. This technology can balance the air pressure inside and outside the casing cavity, meeting requirements for air pressure measurement and sound transmission.

[0003] Blood pressure watches contain components such as an air pump. The air pump needs to be connected to the outside world to allow a large flow of gas to pass through. Existing micropores cannot achieve this, and the waterproof and breathable valves cannot withstand the impact of a large flow of gas. Therefore, the waterproof structure on smartwatches cannot be used on blood pressure watches, as it is impossible to balance waterproofing and the passage of a large flow of gas.

Detailed Implementation

[0063] The blood pressure watch contains a gas inflation and deflation component for inflating and deflating the air bladder. This component is located inside the casing and needs to be connected to the outside air to achieve large-volume inflation and deflation. Therefore, the casing needs to have large or many holes. However, the larger or more numerous the holes, the greater the impact on the waterproof vent valve. This increases the area of ​​the waterproof transparent membrane exposed to air impact, making it more prone to wear or detachment, thus affecting the waterproofness of the casing.

[0064] In view of this, this application improves the waterproof structure by adding a fixing component to fix the waterproof vent valve. The fixing component completely covers the waterproof vent valve and has a vent hole that connects to the inner cavity of the housing. This makes the waterproof vent valve more stable and able to withstand the impact of a large flow of air, thus meeting the requirements of waterproofing and high-flow air circulation for blood pressure watches.

[0065] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0066] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0067] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0068] In one embodiment, a blood pressure watch is provided. This blood pressure watch incorporates a fixing component, with a waterproof vent valve positioned between the fixing component and the housing wall, making the installation of the waterproof vent valve more stable. In particular, when the housing has multiple or large-diameter gas channels, the waterproof vent valve will not loosen due to a small bonding area. The gas impact force borne by the waterproof vent valve will be transferred to the fixing component, thus maintaining the stability of the waterproof vent valve.

[0069] Please refer to Figure 1 and Figure 2 In this embodiment, the blood pressure watch mainly includes a housing 1, an air bladder 2, a gas filling and discharging assembly 3, a waterproof and breathable valve 4, and a fixing component 5.

[0070] The housing 1 includes an upper shell 11 and a lower shell 12, which are fastened together by snap-fit. The upper shell 11 and the lower shell 12 can also be further tightened by screws or other structures to form a stable connection structure.

[0071] The upper shell 11 and the lower shell 12 form a receiving cavity 1a, which is a sealed structure, meaning it is waterproof. A sealing ring or other sealing structure can be provided at the connection between the upper shell 11 and the lower shell 12 to improve the sealing performance of the receiving cavity 1a.

[0072] The gas inflation / deflation assembly 3 is a power source such as an air pump, and it is installed in the accommodating cavity 1a of the housing 1. The airbag 2 is located on the outside of the housing 1, and is generally installed on the inside of the watch strap. The gas inflation / deflation assembly 3 extends through the shell wall of the housing 1 to the outside and connects to the airbag 2, either directly or indirectly. If there is a connection hole or connection port on the shell wall, the connecting end of the gas inflation / deflation assembly 3 passes through the connection hole or connection port on the shell wall and connects to the air nozzle of the airbag 2. The gas inflation / deflation assembly 3 is used to inflate and deflate the airbag 2 to achieve air pressure measurement.

[0073] The housing 1 also contains components such as a pressure sensor 6, a circuit board, and a battery. The pressure sensor 6 extends through the shell wall of the housing 1 to the outside and connects to the airbag 2, either directly or indirectly. If there is a connection hole or connection port on the shell wall, the connection end of the pressure sensor 6 passes through the connection hole or connection port on the shell wall and connects to the air nozzle of the airbag 2. The pressure sensor 6 is used to measure the air pressure of the airbag 2 to detect the blood pressure of the human body.

[0074] The connection holes or ports on the housing 1 through which the gas charging / discharging assembly 3 and pressure sensor 6 pass will be sealed. For example, a sealing ring may be provided on the connection hole or port, and the connection ends of the gas charging / discharging assembly 3 and pressure sensor 6 may be inserted into the sealing ring for sealing. Alternatively, the end of the airbag 2 may be placed against the outer surface of the housing 1, and the airbag 2 may block the connection holes or ports on the housing 1.

[0075] In this embodiment, the housing 1 is provided with a gas channel 13 that penetrates the cavity wall of the housing 1. The gas channel 13 is preferably located on the bottom wall of the lower housing 12, so that the gas channel 13 can be hidden during the wearing of the blood pressure watch, making it more aesthetically pleasing. In other embodiments, the gas channel 13 can also be located on the bottom wall of the upper housing 11, which can also enable the cavity 1a to communicate with the outside air.

[0076] In this embodiment, the gas channel 13 has a porous structure with a certain aperture to allow a large flow rate of gas to pass through. Preferably, multiple gas channels 13 are provided. By providing multiple gas channels 13, the total gas throughput can be increased, the aperture of a single gas channel 13 can be reduced, water and impurities can be prevented from entering the pore, and the stability of the structure can be improved.

[0077] The gas channels 13 can be set in four or other quantities. Four gas channels 13 can be arranged side by side or arrayed in one area to make it easier to completely cover a waterproof and breathable valve 4.

[0078] The waterproof and breathable valve 4 can be a waterproof and breathable membrane, or it can be made of other waterproof and breathable materials or structures. The waterproof and breathable valve 4 is attached to the outer wall of the lower shell 12, covering the outer ends of all gas channels 13. The waterproof and breathable valve 4 has both waterproof and breathable functions, allowing the housing cavity 1a of the shell 1 to communicate with the outside air, but preventing water and dust particles from entering the housing cavity 1a, thus protecting the components inside the housing cavity 1a.

[0079] The fastener 5 is a sheet or block structure, and is made of metal or hard plastic. The fastener 5 is located in the accommodating cavity 1a of the housing 1, and covers the waterproof and breathable valve 4. The area of ​​the fastener 5 is larger than the area of ​​the waterproof and breathable valve 4. The area of ​​the fastener 5 that extends beyond the waterproof and breathable valve 4 is secured to the inner wall of the lower housing 12 by screws 51.

[0080] The fastener 5 is provided with multiple vent holes 52, which are aligned with multiple gas channels 13. The vent holes 52 and the gas channels 13 form a complete ventilation channel. The accommodating cavity 1a inside the housing 1 is connected to the outside air through the gas channel 13, the waterproof and breathable valve 4, and the vent holes 52.

[0081] In other embodiments, the area of ​​the fastener 5 can also be equal to the area of ​​the waterproof and breathable valve 4. The fastener 5 can also completely cover the waterproof and breathable valve 4 and completely fix the waterproof and breathable valve 4. The fastener 5 can also be fixedly connected to the lower shell 12 by means of bonding, welding or other methods.

[0082] In other embodiments, a groove 14 is provided on the outer bottom surface of the lower shell 12. The waterproof and breathable valve 4 and the fixing member 5 are installed in the groove 14. The fixing member 5 fixes the waterproof and breathable valve 4 to the bottom of the groove 14, and the surface of the fixing member 5 protruding from the groove 14 is flush with the outer bottom surface of the lower shell 12. Setting the groove 14 on the outside of the shell 1 can also hide the installation of the waterproof and breathable valve 4 and the fixing member 5, making the exterior and interior of the shell 1 relatively flat and aesthetically pleasing. This is beneficial for the installation of internal components and also improves wearing comfort.

[0083] In this embodiment of the blood pressure watch, the gas channel 13 is covered with a waterproof and breathable valve 4, which allows the gas channel 13 to communicate with the air inside the housing 1 and prevents water from entering the housing 1. Furthermore, the waterproof and breathable valve 4 is covered and fixed by a fastener 5, and the airflow impact force on the waterproof and breathable valve 4 is transmitted to the fastener 5, so that the waterproof and breathable valve 4 can maintain stability and have a better waterproof effect when a large flow of gas enters and exits. Therefore, the waterproof structure of this blood pressure watch can take into account both waterproofing and large flow of gas.

[0084] In one embodiment, a blood pressure watch is provided. The difference between this blood pressure watch and the one described above is that the waterproof and breathable valve 4 and the fixing member 5 are disposed on the outside of the housing 1, and the housing 1 is provided with a recessed area.

[0085] Please refer to Figures 3 to 11 In this embodiment, a waterproof rubber ring 16 is provided between the upper shell 11 and the lower shell 12. The waterproof rubber ring 16 is used to seal the connection gap between the upper shell 11 and the lower shell 12.

[0086] The housing 1 mainly houses a gas charging and discharging device 3, a pressure sensor 6, a circuit board 7, and a battery 8 in its accommodating cavity 1a. The gas charging and discharging device 3 and the pressure sensor 6 are installed together, and the gas charging and discharging device 3, the pressure sensor 6, and the battery 8 are all installed on the circuit board 7.

[0087] The top surface of the upper shell 11 is provided with a display screen 17, and a sapphire glass 18 is also installed on the display screen 17. Buttons are provided on the side of the upper shell 11. The display screen 17, buttons and other components are all connected to the circuit board 7.

[0088] The housing 1 also has watch straps 9 on both sides. The watch straps 9 include a first watch strap 91 and a second watch strap 92. The first watch strap 91 and the second watch strap 92 are respectively connected to the two sides of the housing 1. The airbag 2 is installed on the inner side of the first watch strap 91 (the side facing the wrist of the test subject). The airbag 2 can be connected to the first watch strap 91 through a connecting structure, or the airbag 2 and the first watch strap can be integrated into one structure.

[0089] In this embodiment, the bottom surface of the lower shell 12 is provided with a recessed area 15. The recessed area 15 is a concave structure, and the edge of the concave structure forms an opening along the edge of the lower shell 12, so that one end of the airbag 2 can be inserted into the recessed area 15 from the side of the lower shell 12. The depth of the recessed area 15 is greater than or equal to the thickness of the end of the airbag 2, so that after the end of the airbag 2 is connected to the recessed area 15, the inner side of the end of the airbag 2 is flush with the bottom surface of the lower shell 12, which helps to improve wearing comfort.

[0090] In this embodiment, multiple gas channels 13 are arranged at the bottom of the sinking area 15, and a waterproof and breathable valve 4 is attached to the bottom surface of the sinking area 15. The waterproof and breathable valve 4 blocks all the gas channels 13. The fixing member 5 is installed at the bottom of the sinking area 15 and completely covers the waterproof and breathable valve 4. The fixing member 5 can be fixed in the sinking area 15 by means of screws, adhesives or welding.

[0091] The fastener 5 is completely hidden within the sunken area 15, and the depth of the sunken area 15 is greater than the combined height of the waterproof and breathable valve 4 and the fastener 5, so that there is still space in the sunken area 15 to install the airbag 2.

[0092] The sinking area 15 is also provided with an opening 19, which is connected to the accommodating cavity 1a inside the housing 1. The connection end of the gas charging and discharging device 3 and the connection end of the pressure sensor 6 are exposed from the opening 19 so that the connection end of the gas charging and discharging device 3 and the connection end of the pressure sensor 6 can be connected to the air nozzle 25 of the airbag 2 respectively. The airbag 2 is provided with a protruding connection terminal, which is used to block the opening 19. The connection terminal is provided with two air nozzles 25, which are connected to the connection end of the gas charging and discharging device 3 and the connection end of the pressure sensor 6 respectively.

[0093] In this embodiment, the airbag 2 is made entirely of silicone. One end of the airbag 2 is a silicone end, which is inserted into the recessed area 15 and connected to the lower shell 12. The silicone end can be fixed to the recessed area 15 of the lower shell 12 by means of screws 24 or other means. The silicone end of the airbag 2 is adapted to the recessed area 15, and the silicone end of the airbag 2 fills the recessed area 15 completely, so that there is no gap between the edge of the recessed area 15 and the airbag 2, which can reduce the possibility of dirt and grime accumulating.

[0094] The airbag 2 is a flexible silicone structure, which allows one end of the airbag 2 to be sealed to the recessed area 15 of the lower shell 12. To secure the airbag 2, a reinforcing plate 26 is provided at the end where the airbag 2 connects to the recessed area 15. The reinforcing plate 26 can be embedded inside one end of the airbag 2, or it can be installed on the outside of one end of the airbag 2, both methods improving the structural strength of that end. The reinforcing plate 26 can be made of a rigid material such as a metal plate to further enhance the structural strength of the airbag 2 end. The reinforcing plate 26 can also have clearance holes for screws 24 and air nozzles 25.

[0095] The silicone end of the airbag 2 has a mounting groove 21 and a ventilation groove 22 on the side facing the lower shell 12. The mounting groove 21 corresponds to the fixing member 5 and is larger than the fixing member 5. The mounting groove 21 has sufficient depth to accommodate the waterproof and breathable valve 4 protruding from the recessed area 15 and the fixing member 5 within the mounting groove 21 of the airbag 2. The mounting groove 21 does not block the ventilation hole 52 on the fixing member 5. One end of the ventilation groove 22 is connected to the mounting groove 21, and the other end of the ventilation groove 22 extends away from the mounting groove 21 (away from the shell 1). The other end of the ventilation groove 22 is located in an area not covered by the lower shell 12, forming an opening. This allows the ventilation hole 52 of the fixing member 5 to communicate with the outside air through the mounting groove 21 and the ventilation groove 22 in sequence. This allows the waterproof and breathable valve 4 and the fixing member 5 located on the outside of the shell 1 to be hidden, and allows the accommodating cavity 1a inside the shell 1 to communicate with the outside air.

[0096] Please refer to Figure 12 In other embodiments, a filter device 23 may be installed at the connection between the mounting groove 21 and the ventilation groove 22. The filter device 23 may be a filter screen or a gap-filled baffle. The filter device 23 is used to filter dust or large particles to prevent dust or large particles from entering the mounting groove 21, thereby preventing dust or large particles from blocking the ventilation holes 52 on the fixing member 5 and entering the receiving cavity 1a of the housing 1.

[0097] In other embodiments, the filter device 23 may also be located at one end of the ventilation slot 22 that is exposed outside the housing 1, and may also be used to filter dust or large particles.

[0098] In other embodiments, the fastener 5 can also be part of the airbag 2, and the airbag 2 can directly fix the waterproof and breathable valve 4 in the sinking area 15, which can also achieve the fixation of the waterproof and breathable valve 4.

[0099] In other embodiments, the fastener 5 may also be part of the watch strap 3, such as the fastener 5 being part of the first watch strap 31, with a portion of the first watch strap 31 extending into the recessed area 15, which can also achieve the fixation of the waterproof and breathable valve 4.

[0100] In this embodiment, the waterproof and breathable valve 4 and the fastener 5 are set on the outside of the housing 1 and hidden by the airbag 2, so that the accommodating cavity 1a has a larger volume to install a larger battery. The outside is hidden by the airbag 2, which can achieve dustproof and waterproof efficiency, and is more beautiful and more comfortable to wear.

[0101] In one embodiment, a blood pressure watch is provided, which differs from the above embodiments in that the waterproof and breathable valve 4 and the fixing member 5 are disposed on the inner side of the housing 1.

[0102] Please refer to Figure 13 and Figure 14 In this embodiment, the waterproof and breathable valve 4 and the fixing member 5 are disposed on the inner side of the housing 1, and are located within the accommodating cavity. Specifically, the waterproof and breathable valve 4 and the fixing member 5 are disposed on the inner side of the lower housing 12. The fixing member 5 can also be fixed to the lower housing 12 by means of screws or the like. The accommodating cavity 1a within the housing 1 is connected to the external air in sequence through the fixing member 5, the waterproof and breathable valve 4, and the gas channel 13.

[0103] In this embodiment, the waterproof and breathable valve 4 and the fixing member 5 are set inside the housing 1, which can also achieve waterproofing and ventilation between the accommodating cavity 1a inside the housing 1 and the outside, and can also improve the stability of the installation of the waterproof and breathable valve 4, which is beneficial to improving the waterproof performance and ventilation performance.

[0104] In one embodiment, a blood pressure watch is provided, which differs from the blood pressure watch in that the structure of the gas channel 13 is different.

[0105] Please refer to Figure 15 In this embodiment, the gas channel 13 includes a first channel 131 and a second channel 132. The outer end of the first channel 131 is connected to the outside air, and the inner end of the first channel 131 is connected to the outer end of the second channel 132. The inner end of the second channel 132 is connected to the waterproof and breathable valve 4. The inner diameter of the first channel 131 is larger than the inner diameter of the second channel 132. This arrangement can increase the airflow and prevent impurities and water from entering the second channel 132, which is beneficial to improving the waterproof and breathable effect. The aperture of the fixing member 5 is the same as that of the second channel 132, so that the apertures on both sides of the waterproof and breathable valve 4 are the same, which is beneficial to improving the stability of air intake and exhaust of the waterproof and breathable valve 4.

[0106] In other embodiments, the apertures of the first channel 131 and the second channel 132 may also be the same.

[0116] In other embodiments, the fastener 5 can be fixed in the groove by means of screws, adhesives, or the like.

[0117] In this embodiment, the shape of the fastener 5 is adapted to the groove 14, so that the fastener 5 is completely embedded in the groove 14. The fastener 5 is exposed on the surface of the groove 14 and is flush with the inner side of the lower shell 12, so that the shell 1 has a flatter receiving cavity 1a, which is beneficial to the installation of internal components.

[0118] In other embodiments, the fastener 5 may also protrude from the groove 14, and the fastener 5 may also fix the waterproof and breathable valve 4 in the groove 14.

[0119] Please refer to Figure 20In other embodiments, the shorter gas channel 13 can also be configured as a gradually changing aperture, such as a conical or flared hole. The outer and inner ends of the gas channel 13 have different aperture sizes. The two ends of the conical or flared hole are a large opening and a small opening, respectively. The large opening of the gas channel 13 is located on the outer side, and the small opening is located on the inner side. The aperture of the small opening is equal to the aperture of the vent 52 of the fixing member 5.

[0120] Please refer to Figure 21 In other embodiments, the larger end of the gas channel 13 may be located on the inner side, and the smaller end of the gas channel 13 may be located on the outer side, with the diameter of the larger end being equal to the diameter of the vent hole 52 of the fixing member 5.

[0121] In one embodiment, a blood pressure watch is provided, which differs from the blood pressure watch in that the structure of the gas channel 13 is different.

[0122] Please refer to Figure 22 In this embodiment, the first channel 131 and the second channel 132 have a certain angle between them. The first channel 131 and the second channel 132 are not located on a straight line, forming a bent gas channel, which is beneficial to blocking the entry of external dust.

[0123] Specifically, the first channel 131 is inclined relative to the lower shell 12, and the second channel 132 is perpendicular to the lower shell 12. The connection between the first channel 131 and the second channel 132 forms a corner structure. The first channel 131 is set to be perpendicular to the lower shell 12, and the second channel 132 is set to be inclined relative to the lower shell 12, or both the first channel 131 and the second channel 132 are inclined relative to the lower shell 12, all of which can form a certain angle between the first channel 131 and the second channel 132.

[0124] The included angle between the first channel 131 and the second channel 132 can be in the range of 0° to 180°. The specific value of the included angle between the first channel 131 and the second channel 132 can be set according to requirements.
