Description

Technical Field

[0001] The utility model relates to the technical field of blood pressure monitors, in particular to a dynamic blood pressure monitor. Background Art

[0002] Dynamic blood pressure monitors are medical instruments that are worn for a long time, so they place extremely high demands on the battery life of the device. Currently, most dynamic blood pressure monitors have two solutions to the battery life problem. The first is to use large-capacity, multi-cell dry batteries or lithium batteries as the power source of the device. The cost of meeting the battery life is that the overall shape of the device becomes larger. Because it is necessary to consider accommodating multiple, large-volume batteries, the internal layout of the structure is redundant, and a large amount of internal space is left blank and not fully utilized, resulting in a large overall size of the device and inconvenience in carrying. The second is to sacrifice the function of the device at the expense of, such as canceling the color screen display solution and using a low-power broken-code screen display instead, canceling the device's buzzer alarm function, Bluetooth function, indicator light and other power-consuming functions to extremely compress the product's power consumption, thereby solving the battery life problem of the device. However, in this way, the blood pressure monitor has fewer device functions and cannot meet the diverse usage needs of users. Utility Model Content

[0032] Combine the following Figure 1-Figure 6 The following describes a dynamic blood pressure monitor 100 provided by the present invention.

[0033] In the conventional technology, the blood pressure monitor has a short battery life and is large in size and difficult to carry. To address the problems in the prior art, the utility model provides a dynamic blood pressure monitor 100, including: a housing 110, a sensor assembly 120, a battery assembly 130 and a display assembly 140.

[0034] See also Figure 1 The shell 110 includes a first shell 111 and a second shell 112 that are detachably connected. The shell 110 has a accommodating cavity 113. One end of the shell 110 is provided with an end surface opening 114 that is connected to the accommodating cavity 113. The first shell 111 and the second shell 112 can be detachably connected by a snap or by a bolt. The accommodating cavity 113 can be formed in the second shell 112, and the first shell 111 only realizes the function of a cover plate, or half of the accommodating cavity 113 is formed in the first shell 111 and the other half is formed in the second shell 112. The utility model does not limit this.

[0035] The sensing assembly 120 is disposed in the accommodating cavity 113, and includes an air pump 121, a connecting pipeline 122, a blood pressure board PCBA123 and a pressure sensor 124. The connecting pipeline 122 is connected to the air outlet 128 of the air pump 121, the blood pressure board PCBA123 is disposed on the air pump 121, and the pressure sensor 124 is disposed on the connecting pipeline 122 and is electrically connected to the blood pressure board PCBA123.

[0036] The battery assembly 130 includes a battery compartment 131 and a battery 132. The battery compartment 131 is arranged on one side of the second shell 112, and the battery 132 is arranged on the first shell 111. When the first shell 111 is connected to the second shell 112, the battery 132 is arranged in the battery compartment 131. In the conventional technology, a cylindrical battery with a spring is often used. However, when the device is subjected to mechanical vibration, impact, or falling, there is a risk that the battery and the shrapnel are instantly separated. In the conventional technology, there are also lithium batteries such as 18650, which are large in volume and heavy in weight. In order to make the battery electrode more firmly fit on the spring, the negative electrode spring stiffness is often increased. However, this method makes the battery difficult to disassemble. In the technical solution provided by the utility model, when the user replaces the battery 132, it is only necessary to disassemble the first shell 111, and the battery 132 will be disassembled together with the first shell 111, eliminating the need to "dig" or "pry" to disassemble the battery 132, which significantly improves the convenience of disassembling the battery 132.

[0037] The display assembly 140 is disposed at the end opening 114 , and includes an end shell 141 , a display screen 142 , and a cuff connector 143 . The cuff connector 143 is connected to an end of the connecting pipe 122 away from the air outlet 128 .

[0038] The dynamic blood pressure monitor 100 provided by the utility model can improve the utilization rate of the internal space of the device through the reasonable layout of the sensor component 120, the battery component 130 and the display component 140, thereby reducing the size of the device and making the device convenient to carry; further, the battery component 130 includes a battery 132 arranged in the first shell 111 and a battery compartment 131 arranged in the second shell 112. When the first shell 111 is disassembled, the battery 132 will be separated from the battery compartment 131, which can facilitate the disassembly of the battery 132.

[0039] Specifically, see Figure 2 as well as Figure 3, the connecting pipeline 122 includes a first four-way pipe 125 and a second four-way pipe 126, the first joint of the first four-way pipe 125 is connected to the air outlet 128, the second joint and the third joint of the first four-way pipe 125 are respectively connected to the pressure sensor 124, the fourth joint of the first four-way pipe 125 is connected to the first joint of the second four-way pipe 126; the second joint and the third joint of the second four-way pipe 126 are respectively connected to the micro valve 127, and the fourth joint of the second four-way pipe 126 is connected to the cuff joint 143. In addition, the first four-way pipe 125 and the second four-way pipe 126 are both made of flexible materials. The utility model uses an "integrated" connecting pipeline 122, and sets a flexible first four-way pipe 125 and a second four-way pipe 126 to be directly plugged with the air pump 121, the micro valve 127, etc. Compared with the traditional silicone tube + PP pagoda joint connection method, this connection method greatly reduces the number of joints, reduces the probability of air leakage, and saves space, which is conducive to reducing the volume of the device itself.

[0040] Furthermore, a plug rod is provided on the pressure sensor 124, and the plug rod is plugged into the second joint and the third joint of the first four-way pipe 125, and the end of the pressure sensor 124 is welded to the blood pressure board PCBA123. It should be noted that the blood pressure board PCBA123 is directly arranged on the air pump 121, and the connecting pipeline 122 is arranged on one side of the air pump 121. When the pressure sensor 124 is arranged on the connecting pipeline 122, it is just at the same horizontal plane as the blood pressure board PCBA123, which facilitates the welding connection between the two.

[0041] Specifically, see Figure 4 In the technical solution provided by the utility model, the battery assembly 130 includes a shelf 133 arranged on one side of the second shell 112, and the shelf 133 and the second shell 112 are enclosed to form a battery compartment 131; a positive spring 134 and a negative spring 135 are also provided in the battery compartment 131, and the positive spring 134 and the negative spring 135 are used to connect with the two ends of the battery 132 respectively. There are traditional external battery structures on the market, which are to add shields, shells 110 and other structural parts to the battery to form components such as "battery packs" and "battery boxes", and contacts such as spring pins and springs are designed on the components. After assembly, the contacts of the device body contact the contacts of the battery box to form a passage. The utility model eliminates the above-mentioned "contact" type assembly method, directly contacts the battery 132 with the spring, and reduces the risk of poor contact when using the contacts.

[0042] In addition, it should be noted that the first housing 111 is provided with a battery opening 115, and the battery assembly 130 further includes a battery plate 136 disposed at the battery opening 115, and the battery 132 is disposed on the battery plate 136. By disposing the battery plate 136, the battery 132 can be removed from the battery compartment 131 by simply removing the battery plate 136, without removing the first housing 111, making the removal of the battery 132 easier. For further information, please refer to Figure 5 A plurality of wing-shaped clamping plates 137 are provided on one side of the battery board 136 close to the second housing 112. The wing-shaped clamping plates 137 are arranged at intervals along the edge of the battery 132. When the battery 132 is placed in the first housing 111, each wing-shaped clamping plate 137 is clamped with the outer edge of the battery 132. The wing-shaped clamping plates 137 embrace the battery 132, which can not only fix the battery 132 well, but also facilitate the removal of the battery 132 from the battery board 136.

[0043] Furthermore, the battery panel 136 can be connected to the first housing 111 by snap-fit ​​connection, so that it can be easily disassembled. The first housing 111 is provided with a plurality of mounting holes, and the battery panel 136 is provided with a plurality of bolts. The first housing 111 and the second housing 112 are detachably connected by bolt connection.

[0044] See also Figure 6 The end shell 141 is also provided with a button 147, which is electrically connected to the display screen 142 and is used to adjust the device parameters. It should be noted that the dynamic blood pressure monitor 100 also includes a PCB board arranged in the accommodating cavity 113, and the button 147 is arranged on the PCB board. This is a prior art and the utility model does not elaborate on it. It should be noted that a plurality of installation windows are provided on the end shell 141 for installing the button 147 and the display screen 142.

[0045] In order to facilitate the use of users, in general, an aperture is set on the button for easy identification. The traditional button with an "aperture" is made by covering the LED light on the PCB board with a silicone button, adding color powder during the vulcanization process of the silicone button to form a uniform scattered light effect, and then using the process of oil spraying + laser engraving to carve "aperture", "pattern" and other shapes on the silicone button to finally achieve luminescence. However, the above production process is relatively complicated and the final button has a poor feel.

[0046] In the technical solution provided by the utility model, a plurality of lamp beads 144 are arranged around the button 147, and the end face of the button 147 is covered with a light guide ring 145 and a film 146 in sequence, and the light guide ring 145 is arranged corresponding to each lamp bead 144. The utility model arranges four lamp beads 144 evenly around the button 147, covers the light guide ring 145 formed by vulcanization of silicone + toner above the lamp beads 144, and covers the film 146 above the silicone, and uses the "fog white" effect on the film 146 to depict the required aperture, and finally achieves the effect of turning four point light sources into apertures. Because there is a thin piece of silicone between the external film 146 and the button 147, this solution has a very good feel compared to traditional membrane buttons. It should be noted that the film 146 not only covers the surface of the button 147, but also covers the surface of the entire end shell 141.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
