[0048] Example one:
[0049] This embodiment provides a watch type electronic blood pressure monitor.
[0050] Please refer to figure 2 , The watch type electronic blood pressure monitor 100 can be worn on the user's wrist W like a watch. It usually includes an inflator unit (not shown in the figure) and an airbag 130, the inflator unit is in communication with the airbag 130, and the airbag 130 can be inflated. When measuring blood pressure, the sphygmomanometer only needs to tie the airbag 130 directly to the limb without using a cloth bag, which effectively improves hygiene, comfort, and aesthetics.
[0051] Of course, please refer to Figure 2-4 The wristwatch type electronic blood pressure monitor 100 usually further includes a body 110 and a strap 120. In addition to the inflator unit, the body 110 also has other components such as a pressure sensor and a control unit. The watchband 120 is mounted on the body 110 for easy wearing. Both the inflation unit and the pressure sensor are in communication with the airbag 130, and the pressure sensor and the control unit are not shown in the figure. The airbag 130 is located on the inner side of the watch band 120 for contact with the wrist W of the wearer. The airbag 130 is fixedly installed on the strap 120, and may be detachably installed or non-detachable. In addition, the airbag 130 can also be designed as an integral structure with the watch band 120.
[0052] The airbag 130 includes a bag body enclosing a sealed cavity. The bag body includes a fitting part and a connecting part. The fitting part is the area on the bag body that is used to fit the wearer's wrist W. That is, the part of the bag body on the airbag 130 that is used to contact the wearer's wrist W is regarded as a fit. unit. The connecting portion is connected to the periphery of the fitting portion in a sealed manner, and the connecting portion and the fitting portion are enclosed to form a sealed cavity, that is, except for the fitting portion of the airbag 130, other parts of the bag body are all connecting portions. The sealed cavity has air holes, which are used for inflation and deflation. There can be one or several air holes, and the same air hole can be used for inflation and deflation, or separate air holes can be used for inflation and deflation.
[0053] Among them, please refer to Figure 6-8 At least a part of the connecting portion is the elastic deformation area 1301, that is, the connecting portion may be all the elastic deformation area 1301, or only a part may be the elastic deformation area 1301. The elastic deformation region 1301 may be provided in only one place or in multiple places. The elastic deformation area 1301 can be deformed before the attachment portion during inflation. When the airbag 130 is inflated, the air pressure inside the airbag 130 increases, and the elastic deformation area 1301 will firstly deform, thereby increasing the thickness of the airbag 130, so that the fitting part is close to the wearer's wrist. Since the fitting portion and the elastic deformation region 1301 have different deformation sequences, when the elastic deformation region 1301 is stretched, the fitting portion can remain basically unchanged, thereby reducing the change in the contact area between the fitting portion and the wearer. By adjusting the inflation air pressure, it is possible to prevent the fitting part from being deformed as much as possible, thereby keeping the contact area with the wearer as consistent as possible, and improving the accuracy of blood pressure measurement.
[0054] This way of preferentially deforming the elastically deformed area 1301 can be designed in terms of structure and material, so that the elastically deformable area 1301 has a structure and/or material that deforms before the fitting portion when inflated. For example, please refer to Image 6 In terms of structure, the elastic deformation region 1301 has a corrugated structure. Compared with the generally flat-shaped fitting part, this corrugated structure is easier to expand when pressurized, thereby expanding the volume of the airbag 130 and avoiding deformation of the fitting part under air pressure. Of course, this corrugated structure is only an example, and the above-mentioned elastic deformation area 1301 can also be realized by other structures. For example, in some embodiments, the thickness of the elastic deformation area 1301 may be greater than that of the bonding portion. The thickness is thinner, so that it will preferentially deform under the same pressure.
[0055] In addition, the above-mentioned purpose can also be achieved from the selection of materials. For example, the elastic deformation region 1301 is made of a material that is more easily deformed when inflated than the fitting portion. Generally, the airbag 130 is made of rubber. Therefore, in an embodiment, the elastic deformation area 1301 and the attaching part may be made of different rubbers, and the rubber used to make the elastic deformation area 1301 may have a better fit The rubber used in the part is more easily deformed.
[0056] The foregoing does not enumerate all the ways that the elastic deformation region 1301 can be deformed preferentially. However, under the inventive concept disclosed in this embodiment, those skilled in the art can easily think of other implementation means, which will not be repeated here. The various methods described above for achieving preferential deformation of the elastic deformation region 1301 can be applied individually or in combination.
[0057] Further, please refer to Figure 5 In one embodiment, the bag body of the airbag 130 includes a lower wall body 131 for contact with the wearer's wrist W, an upper wall body 132 opposite to the lower wall body 131, and an upper wall body 132 connected to the lower wall body The side wall 133 between 131 (the signs such as 133a in parentheses in the figure are further divisions of the side wall 133, and this division is not necessary), and the bonding part is at least a part of the lower wall 131, that is, the The lower wall body 131 may all be used as the bonding part, or only a part thereof may be used as the bonding part. The upper wall 132 can be provided with an air hole 134 for inflating and discharging air.
[0058] Please refer to Image 6 In an embodiment, the elastically deformable area 1301 may be located on the side wall 133. Wherein, the elastic deformation region 1301 may be one or more places, which may be arranged in a certain place of the side wall body 133, or may be dispersed in multiple positions of the side wall body 133. When the elastic deformation area 1301 is provided on the side wall 133, when the airbag 130 is inflated, the upper wall 132 will move upward with respect to the lower wall 131, thereby increasing the thickness of the airbag 130 and making the airbag 130 fit well W part of the wearer's wrist. In this way, the lower wall 131 can be deformed as little as possible during the entire inflation process.
[0059] Of course, it is preferable that the elastic deformation area 1301 is located on two sidewall bodies 133 (for example, the left side wall 133c and the right side wall 133d) arranged opposite to each other on the two sides of the bonding part, so that the elastic deformation area 1301 The deformation is simultaneously performed on both sides of the bonding part, thereby further reducing the deformation of the lower wall 131.
[0060] Please refer to Figure 5 with 6 In a preferred embodiment, the sidewall body 133 includes a front sidewall body 133a, a rear sidewall body 133b opposite to the front sidewall body 133a, and a connection between the front sidewall body 133a and the rear sidewall body 133b. Between the left side wall 133c and the right side wall 133d. The front side wall 133a is arranged at one end of the upper wall 132 and the lower wall 131 close to the main body of the watch-type sphygmomanometer along the winding direction of the airbag 130, and the rear side wall 133b is arranged on the upper wall 132 and the lower wall 131 away from the watch-type blood pressure Calculate one end of the main body. The left side wall 133c and the right side wall 133d are located on both sides of the upper wall 132 and the lower wall 131. Such an airbag 130 basically has a cube or a cuboid cavity, wherein the elastic deformation area 1301 is located on the left side wall 133c and/or the right side wall 133d.
[0061] Of course, it’s better, please refer to Image 6 The elastic deformation zone 1301 is located on the left side wall 133c and the right side wall 133d at the same time. The left side wall 133c and the right side wall 133d are respectively located on both sides of the fitting part, and are arranged along the winding direction of the watch band 120 and the airbag 130, so that the left side wall 133c and the right side wall 133d can be better maintained Synchronous deformation to maintain the stability of the bonding part.
[0062] Please continue to refer Image 6 When the airbag 130 is inflated, the upper wall 132 receives the force F1, the lower wall 131 receives the force F2, the elastic deformation area 1301 of the left wall 133c receives the force F3, and the elastic deformation area 1301 of the right wall 133d receives the force F3. 力 F4. The elastic deformation zone 1301 is subjected to various forces so that it is easily bent and deformed, while the upper wall 132 is restrained by the limbs, and the lower wall 131 is restrained by the strap 120, which is basically difficult to deform. As a result, the elastic deformation zone 1301 is deformed, the upper wall 132 and the lower wall 131 move away from each other, the distance between the upper wall 132 and the lower wall 131 increases, and the volume of the sealed cavity 1302 of the airbag 130 increases.
[0063] The state when further pressurized to a certain greater pressure. At this time, the upper wall 132 receives a force F5, the lower wall 131 receives a force F6, the elastic deformation area 1301 of the left wall 133c receives a force F7, and the elastic deformation area 1301 of the right wall 133d receives a force F8. As a result, the elastic deformation area 1301 is further deformed to be straightened, the upper wall 132 and the lower wall 131 are further separated, the distance between the upper wall 132 and the lower wall 131 is further increased, and the sealing cavity 1302 of the airbag 130 The volume increases. Under the condition that the width of the winding direction in which the upper wall 132 contacts the limb remains unchanged, the maximum distance between the upper wall 132 and the lower wall 131 can reach H.
[0064] When designing the airbag 130, it is only necessary to consider that the distance between the upper wall 132 and the lower wall 131 does not exceed H during the maximum deformation of the cuff, so that the width dimension of the winding direction of the airbag 130 in contact with the limbs can be maintained during the entire compression process. constant.
[0065] Of course, in other embodiments, the balloon body of the airbag 130 may also have other structures, for example, it includes a lower wall body 131 for contact with the wearer's wrist W and an upper wall body 132 opposite to the lower wall body 131. . The upper wall body 132 and the lower wall body 131 are directly connected in a sealed manner. At this time, it can be regarded that the side wall body 133 is not present or a part of the upper wall body 132 is regarded as the side wall body 133. The bonding part is also at least a part of the lower wall 131.
[0066] Regardless of the structure of the airbag 130, in addition to providing the elastic deformation area 1301 on the side wall body 133, the elastic deformation area 1301 may also be provided on the upper wall body 132.
[0067] Please refer to Figure 7 In an embodiment, the elastic deformation zone 1301 is located on the upper wall 132, and it may be arranged at one or more places on the upper wall 132. When the airbag 130 is inflated, the elastic deformation area 1301 on the upper wall 132 gradually deforms and expands, so that the upper wall 132 moves up, and the airbag 130 expands, so that the lower wall 131 is attached to the wearer's wrist. Together.
[0068] Better, please continue to refer to Figure 7 , The elastic deformation area 1301 is arranged on two sides of the upper wall 132 oppositely. In this way, two opposite elastic deformation regions 1301 can be deformed at the same time, so as to ensure a smooth upward movement process of the upper wall 132, thereby ensuring the stability of the lower wall 131.
[0069] Further, the elastic deformation area 1301 can also be provided on the lower wall 131. Please refer to Figure 8 In one embodiment, the bonding portion 1311 is a part of the lower wall 131 and is located in the middle of the lower wall 131. The elastic deformation area 1301 is disposed on the lower wall body 131 and located at the side of the bonding portion 1311. When the airbag 130 is inflated, the elastic deformation area 1301 of the lower wall 131 will be deformed, that is, the side of the fitting portion 1311 will be deformed, but the fitting portion 1311 itself can still be basically stable to ensure measurement accuracy.
[0070] Of course, please continue to refer to Figure 8 Preferably, the elastically deformable regions 1301 are relatively provided on two sides of the bonding portion 1311. Therefore, during inflation, both sides of the bonding portion 1311 are deformed at the same time, which prevents the bonding portion 1311 from changing due to one side being pulled, and further reduces the amount of deformation of the bonding portion 1311.
[0071] Although the above description takes a watch-type sphygmomanometer as an example, the above-mentioned airbag can be applied not only to a watch-type sphygmomanometer, but also to various types of sphygmomanometers such as wrist-type sphygmomanometers and arm-type sphygmomanometers. In addition, the airbag can also be applied to various other devices that require blood pressure measurement.
