Description

Air bag, watch type sphygmomanometer, blood pressure measuring module and vital sign monitor

Technical Field

The application relates to an electronic sphygmomanometer, in particular to an air bag structure of the electronic sphygmomanometer.

Background

The cuff of a wrist sphygmomanometer is generally composed of a cloth bag and an air bag embedded in the cloth bag. The air bag is arranged in the cloth bag and protected by the cloth bag, but the cloth bag also restricts the expansion of the air bag, and simultaneously, the limb is isolated from the air bag, and the pulse signal transmitted to the air bag is weakened, thereby affecting the measurement precision. Moreover, this structure also has the disadvantages of poor hygiene, comfort and aesthetic appearance, and is not suitable for a wrist watch type sphygmomanometer worn on the limbs for a long time.

In view of the above, chinese patent CN 205568936U "discloses a sphygmomanometer cuff and a watch type electronic sphygmomanometer, wherein the cuff includes an air bag. This gasbag is including sealed air chamber and the air cock that is used for communicating this air chamber with sphygmomanometer body gas circuit, and this air chamber has initial volume, and this air cock communicates with this air chamber. The cuff eliminates a cloth bag, overcomes the adverse effect of the cloth bag on the air bag, and effectively improves the sanitation, the comfort and the aesthetic property. However, such an airbag has the following problems:

during the compression process the two sides of the cuff (air bag) contract towards the middle and are pulled towards the middle, the middle of the air bag expands and bulges (as shown in fig. 1), as a result of which the width b of the air bag (cuff) pressing the limb is much smaller than the initial width a of the air bag, i.e. a > b. For the purpose of beauty, the wrist strap width of the watch type sphygmomanometer is generally required to be not more than the width of the watchband, namely, the width is basically 20-30 mm. If the watch is worn slightly loosely, the two sides of the air bag shrink towards the middle when the air bag is inflated and pressurized, which is easy to reduce by about 10mm, and the width (artery direction) of the limb pressed by the air bag is reduced by 30% or even 50%. In particular, even if the same person wears the watch, the tightness is difficult to be consistent, so that the swelling height h of the middle part of the air bag is inconsistent, and the width b of the compression limb is reduced along with the increase of h. Finally, the wearing tightness is inconsistent, which causes the strength of the pulse signals sensed by the air bag to be inconsistent, thereby causing inaccurate blood pressure measurement.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.

The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

The first embodiment is as follows:

the embodiment provides a watch type electronic sphygmomanometer.

Referring to fig. 2, the wrist watch type electronic blood pressure monitor 100 can be worn on the wrist W of a user like a wristwatch. Which generally includes an inflation unit (not shown) in communication with bladder 130 for inflating bladder 130, and bladder 130. When the sphygmomanometer is used for measuring blood pressure, the air bag 130 only needs to be directly bound along the limb without using a cloth bag, so that the sanitation, the comfort and the attractiveness are effectively improved.

Of course, referring to fig. 2-4, the watch-type electronic blood pressure monitor 100 generally further includes a body 110 and a band 120. The body 110 includes other components such as a pressure sensor and a control unit in addition to the inflation unit. The band 120 is attached to the body 110 for wearing. The inflation unit and the pressure sensor, both of which are not shown in the drawings, communicate with the airbag 130. The bladder 130 is positioned on the inside of the wristband 120 for contact with the wearer's wrist W. The air bag 130 is fixedly mounted on the band 120, and may be detachably mounted or non-detachably mounted. Furthermore, bladder 130 may be integrally formed with wristband 120.

The balloon 130 includes a bladder enclosing a sealed cavity. The balloon includes a fitting portion and a connecting portion, the fitting portion is an area on the balloon for fitting with the wrist W of the wearer, that is, the portion of the balloon on the airbag 130 for contacting with the wrist W of the wearer is regarded as the fitting portion. This connecting portion and laminating portion be sealing connection all around, and connecting portion and laminating portion enclose to close and form sealed chamber, except laminating portion on 130 promptly, other utricule parts are connecting portion. The sealed cavity has air holes for inflation and deflation. The air holes can be one or more, the same air hole can be used for inflation and deflation, and the independent air holes can be used for inflation and deflation.

Referring to fig. 6 to 8, at least a portion of the connecting portion is an elastic deformation region 1301, that is, the connecting portion may be entirely the elastic deformation region 1301, or only a portion of the connecting portion may be the elastic deformation region 1301. The elastic deformation region 1301 may be provided at only one location or at a plurality of locations. The elastically deformable region 1301 can be deformed prior to the attachment portion when inflated. When the air bag 130 is inflated, the air pressure inside the air bag 130 increases, and the elastic deformation region 1301 will deform first, so that the thickness of the air bag 130 increases to make the fitting portion close to the wrist of the wearer. Because the fit portion and the elastic deformation region 1301 have different deformation sequences, the fit portion can be kept unchanged basically when the elastic deformation region 1301 is spread, so that the change of the contact area of the fit portion and a wearer is reduced. Through the adjustment to the inflation pressure, can make laminating portion not produce deformation as far as possible, and then make its area of contact with the person of wearing keep unanimous as far as possible, improve blood pressure measurement's accuracy.

The manner in which the elastically deformable region 1301 is preferentially deformed can be designed in terms of both structure and material, such that the elastically deformable region 1301 has a structure and/or material that deforms prior to the attachment portion when inflated. For example, referring to fig. 6, structurally, the elastically deformable region 1301 has a corrugated structure. Such a corrugated structure is easier to expand when pressurized than a generally planar bonded portion, thereby expanding the volume of the airbag 130 and avoiding deformation of the bonded portion under air pressure. Of course, this corrugated structure is merely an example, and the above-mentioned elastic deformation region 1301 can be implemented by other structures, for example, in some embodiments, the thickness of the elastic deformation region 1301 can be thinner than that of the fitting portion, so that it can be preferentially deformed under the same air pressure.

Further, the above object can be achieved by selecting a material, for example, the elastic deformation region 1301 is made of a material which is more easily deformed than the attachment portion when inflated. The conventional air bag 130 is made of rubber, so that in one embodiment, the elastic deformation region 1301 and the attaching portion can be made of different rubbers, respectively, wherein the rubber of the elastic deformation region 1301 can have a property of being more easily deformed than the rubber of the attaching portion.

The above description does not list all the ways in which the preferential deformation of the elastically deformable region 1301 can be achieved, but other means of realisation will be readily apparent to those skilled in the art, given the inventive concept disclosed in the present application, and will not be further elaborated herein. The various modes for realizing the preferential deformation of the elastic deformation region 1301 shown above can be applied independently or used in combination.

Further, referring to fig. 5, in an embodiment, the bag body of the airbag 130 includes a lower wall 131 for contacting the wrist W of the wearer, an upper wall 132 opposite to the lower wall 131, and a side wall 133 connected between the upper wall 132 and the lower wall 131 (the reference numeral 133a, etc. indicated by parentheses in the figure is a further division of the side wall 133, which is not necessary), and the attaching portion is at least a part of the lower wall 131, that is, the lower wall 131 may be all the attaching portion, or only a part thereof may be the attaching portion. The upper wall 132 may be provided with air holes 134 for air inflation and deflation.

Referring to fig. 6, in an embodiment, the elastically deformable region 1301 may be located on the sidewall 133. The elastically deformable region 1301 may be one or more regions, may be disposed at a certain position of the sidewall 133, or may be dispersed to a plurality of positions of the sidewall 133. When the elastic deformation region 1301 is disposed on the side wall 133, the upper wall 132 moves upward relative to the lower wall 131 when the airbag 130 is inflated, so as to increase the thickness of the airbag 130, and the airbag 130 can be well attached to the wrist W of the wearer. This allows the lower wall 131 to deform as little as possible during the entire inflation process.

Of course, it is preferable that the elastic deformation region 1301 is located on two side walls 133 (e.g., the left side wall 133c and the right side wall 133d) oppositely disposed at two sides of the fitting portion, so that the deformation of the elastic deformation region 1301 is performed at two sides of the fitting portion at the same time, thereby further reducing the deformation of the lower wall 131.

Referring to fig. 5 and 6, in a preferred embodiment, the sidewall 133 includes a front sidewall 133a, a rear sidewall 133b opposite to the front sidewall 133a, and a left sidewall 133c and a right sidewall 133d connected between the front sidewall 133a and the rear sidewall 133 b. The front wall 133a is provided at one end of the upper wall 132 and the lower wall 131 close to the main body of the wristwatch in the winding direction of the air bag 130, and the rear wall 133b is provided at one end of the upper wall 132 and the lower wall 131 far from the main body of the wristwatch. The left sidewall 133c and the right sidewall 133d are located on both sides of the upper and lower walls 132 and 131. Such a balloon 130 has a substantially square or rectangular parallelepiped cavity, wherein the elastically deformable region 1301 is located on the left sidewall 133c and/or the right sidewall 133 d.

Of course, referring to fig. 6, the elastic deformation area 1301 is located on both the left sidewall 133c and the right sidewall 133 d. The left sidewall 133c and the right sidewall 133d are respectively located at both sides of the attachment portion and are arranged along the winding direction of the band 120 and the airbag 130, so that the left sidewall 133c and the right sidewall 133d can be better deformed in synchronization, thereby maintaining the stability of the attachment portion.

With continued reference to fig. 6, when the airbag 130 inflates, the upper wall 132 is under the force F1, the lower wall 131 is under the force F2, the elastically deformable region 1301 of the left side wall 133c is under the force F3, and the elastically deformable region 1301 of the right side wall 133d is under the force F4. The elastic deformation region 1301 is subjected to forces so that the bending deformation can be easily generated, the upper wall body 132 is restrained by the limb, and the lower wall body 131 is restrained by the watchband 120 and is basically difficult to generate the deformation. As a result, the elastic deformation region 1301 is deformed, the upper wall 132 and the lower wall 131 are away from each other, the distance between the upper wall 132 and the lower wall 131 becomes large, and the volume of the sealed chamber 1302 of the airbag 130 increases.

A state when further pressurized to a certain greater pressure. At this time, the upper wall 132 is subjected to a force F5, the lower wall 131 is subjected to a force F6, the elastically deformable region 1301 of the left side wall 133c is subjected to a force F7, and the elastically deformable region 1301 of the right side wall 133d is subjected to a force F8. As a result, the elastically deformed region 1301 is further deformed to be straightened, the upper wall 132 and the lower wall 131 are further away, the distance between the upper wall 132 and the lower wall 131 is further increased, and the volume of the sealed chamber 1302 of the airbag 130 is increased. In the case where the winding direction width dimension of the upper wall 132 in contact with the limb is constant, the maximum distance between the upper wall 132 and the lower wall 131 may reach H.

When the air bag 130 is designed, the width dimension of the air bag 130 in the winding direction contacting with the limb in the whole pressurizing process can be ensured to be kept unchanged only by considering that the distance between the upper wall 132 and the lower wall 131 does not exceed H when the cuff is maximally deformed.

Of course, in other embodiments, the bladder of the airbag 130 may have other configurations, such as a lower wall 131 for contacting the wrist W of the wearer and an upper wall 132 opposite to the lower wall 131. The upper wall 132 and the lower wall 131 are directly connected in a sealing manner, and in this case, the side wall 133 may be omitted or a part of the upper wall 132 may be regarded as the side wall 133. The abutment is also at least a part of the lower wall 131.

Regardless of the structure of the airbag 130, the elastic deformation region 1301 may be disposed on the upper wall 132 in addition to the elastic deformation region 1301 disposed on the side wall 133.

Referring to fig. 7, in one embodiment, the elastically deformable region 1301 is located on the upper wall 132, and may be disposed at one or more positions of the upper wall 132. When the air bag 130 is inflated, the elastic deformation region 1301 on the upper wall 132 gradually deforms and expands, so that the upper wall 132 moves upward, the air bag 130 expands, and the lower wall 131 is attached to the wrist of the wearer.

Preferably, with continued reference to fig. 7, the elastically deformable regions 1301 are oppositely disposed on two sides of the upper wall 132. Therefore, two opposite elastic deformation regions 1301 can deform simultaneously, the stability of the upward moving process of the upper wall body 132 is guaranteed, and the stability of the lower wall body 131 is further guaranteed.

Further, the elastic deformation region 1301 can also be disposed on the lower wall 131. Referring to fig. 8, in an embodiment, the attaching portion 1311 is a portion of the lower wall 131, and is located in a middle portion of the lower wall 131. The elastic deformation region 1301 is provided on the lower wall 131 and located on the side of the attachment portion 1311. When the airbag 130 inflates, the elastic deformation region 1301 of the lower wall body 131 deforms, that is, the side of the attaching portion 1311 deforms, but the attaching portion 1311 can still be basically stable, and the measurement accuracy is guaranteed.

Of course, with continued reference to fig. 8, the elastic deformation regions 1301 are preferably disposed on opposite sides of the attaching portion 1311. Therefore, when the air bag is inflated, the two sides of the attaching portion 1311 are deformed at the same time, so that the attaching portion 1311 is prevented from being changed due to one side being pulled, and the deformation amount of the attaching portion 1311 is further reduced.

Although the above description has been made by taking a wristwatch type sphygmomanometer as an example, the above-described air bag can be applied not only to a wristwatch type sphygmomanometer but also to various types of sphygmomanometers such as a wrist type sphygmomanometer and an arm type sphygmomanometer. In addition, the air bag can also be applied to other various devices which need to measure blood pressure.

Example two:

the second embodiment provides another watch type sphygmomanometer.

In this embodiment, one end of the airbag 130 has a mounting structure, and the airbag 130 is fixedly connected to the main body through the mounting structure. In this configuration, bladder 130 may be secured entirely by the body, or both the body and wristband 120 may be secured simultaneously. The airbag 130 may have the same structure as or a modified structure from the first embodiment.

Referring to fig. 9 and 10, in one embodiment, the mounting structure includes a clip 135, and the airbag 130 is detachably fixed to the main body 110 by the clip 135.

In particular, the bladder 130 may have a connector 132, and the connector 132 may be fixedly mounted within the bladder 130, such as on the upper wall 132. The buckle 135 is fixedly disposed on the connecting member 132, and the main body 110 is correspondingly provided with a structure cooperating with the buckle 135, so as to form a clamping fixation.

Further, referring to fig. 11, in one embodiment, bladder 130 and wristband 120 may be integrally formed. Of course, in other embodiments, bladder 130 and band 120 may be secured by a separate post-manufacture fastening connection.

Referring to fig. 9 and 10, in one embodiment, a hook surface 122 (or a hook surface) of the hook and loop fastener and a loop surface 121 (or a hook surface) of the hook and loop fastener are disposed on a side of the wristband 120 away from the limb. One end a of the band 120 is fixed to the fixing portion of the body 110, and the other end B of the band 120 is fixed to the hair surface 121 after passing through the fixing portion of the body 110.

Example three:

the third embodiment provides a portable blood pressure measuring module, which can be stored at ordinary times, and when blood pressure measurement is needed, the portable blood pressure measuring module can be detachably mounted on the wrist wearing piece to measure blood pressure. The wrist wearing piece includes various articles that can be worn on the wrist W, such as a watch, a bracelet, and a cuff.

Referring to fig. 12-15, the portable blood pressure measuring module 200 includes a body 210, an air bag 230, and a fixing structure 220 for detachably mounting the body 210 to the wrist wearing piece. The body 210 has an inflation unit, a pressure sensor, a control unit, and other related components. Here, the airbag 230 and the related connection relationship thereof are mainly described, and the other structures are not described in detail since they do not relate to the main improvement of the present embodiment.

The inflation cell and pressure sensor are both in communication with the bladder 230, and the inflation cell can inflate the bladder 230, although some inflation cells can also be used as a deflation structure. The pressure sensor is used to detect the pressure in the air bag 230 so that the control unit performs a corresponding control operation. The airbag 230 is mounted on the body 210 for contact with the wrist W of the wearer. The securing structure 230 is primarily for mounting with a wrist-worn device and may include a securing ring or other structure that fits over the wrist-worn device.

The airbag 230 may have the same structure as or a modified structure from the first embodiment. Since the attachment portion 2311 of the air bag 230 and the elastically deformable region 2301 have different deformation sequences, referring to fig. 14 and 15, when the elastically deformable region 2301 is expanded, the attachment portion 2311 can be kept substantially unchanged, so that the change of the contact area between the attachment portion 2311 and the wearer is reduced, and the accuracy of blood pressure measurement is improved.

Example four:

the embodiment provides a vital sign monitor with a blood pressure measuring function. Besides measuring blood pressure information, the method can also realize detection of other vital sign information, such as pulse rate, Mean Arterial Pressure (MAP), blood oxygen saturation (SpO2), body temperature, respiration, electrocardio and the like.

The vital signs monitor comprises an inflation unit and an air bag, and the air bag can adopt any structure shown in the first embodiment to the third embodiment.
