Description

Pressure pulse bag and blood pressure measuring device thereof

The present invention relates to a pressure pulse bag and a blood pressure measuring device thereof, and more particularly to a pressure pulse bag having a fixed means for fixing a detachable pressure sensor and a blood pressure measuring device thereof.

The current common sphygmomanometers are divided into two categories: mercury sphygmomanometers and electronic sphygmomanometers. The mercury sphygmomanometer measures the systolic blood pressure and diastolic blood pressure of the human blood pressure using the pressure values corresponding to the Kodak tone appearance and disappearance time points. However, the mercury sphygmomanometer contains highly toxic mercury, and the mercury sphygmomanometer relies on the human ear to judge the presence or absence of the Korotkoff sound to complete the blood pressure measurement, and thus is susceptible to interference caused by environmental factors and human factors. Therefore, electronic electronic sphygmomanometers have gradually replaced mercury sphygmomanometers.

The principle of the electronic sphygmomanometer is based on the measurement of the blood pressure of the human body. When the arterial blood vessels are completely blocked to half of the diameter, the arterial blood vessels are most shocked by the impact of blood, and the air in the cuff is also affected by the vibration caused by the vibration of the arteries. Therefore, the electronic sphygmomanometer uses the above-mentioned maximum amplitude and a formula established by a large amount of statistical information to estimate the pressure value corresponding to the vibration wave at the time of initial opening of the arterial blood vessel and at the time of complete opening, as the systolic blood pressure and diastolic blood pressure of the human blood pressure. However, the formula established by statistical information does not satisfy each individual's different physiological conditions. Therefore, for some subjects with poor arterial elasticity, the blood pressure value estimated by the electronic sphygmomanometer does not match the actual blood pressure value.

In order to solve the above problem, Japanese Laid-Open Patent Publication No. P2011-13935 discloses a sphygmomanometer that is free from environmental noise and does not use air as a vibration medium. The sphygmomanometer includes a cuff and a piezoelectric element is disposed in the cuff. When the cuff is wrapped around the arm of the subject, the piezoelectric element is located above the artery to sense that the artery is vibrated by blood shock, and An output signal is generated based on the vibration. The sphygmomanometer determines the blood pressure value of the subject according to the change of the output signal.

However, the piezoelectric element has a long life and high cost without frequent replacement, but the cuff for setting the piezoelectric element is easily damaged due to frequent covering and dismounting actions, and is a consumable of the sphygmomanometer. If the pressure element is damaged, the piezoelectric element that is still working normally must be discarded, which will result in waste of resources and excessive maintenance cost of the sphygmomanometer. Therefore, in order to improve the above problems, there is a need for a sphygmomanometer that can improve the conventional deficiency.

The main purpose of this creation is to provide a cuff that can easily replace a detachable pressure sensor.

Please refer to FIG. 2 together. FIG. 2 is a block diagram of the first embodiment of the blood pressure measurement host of the present invention. As shown in FIG. 1 and FIG. 2, the blood pressure measuring host 10 includes a screen 11, a power button 12, a pressurizing button 13, a pressurizing motor 14, and a first set of ports 15 for And a control unit 17, wherein the control unit 17 is electrically connected to the screen 11, the power button 12, the pressurizing button 13, and a pressurizing motor 14, respectively. The cuff 20 includes a detachable pressure sensor 21, a covering member 22, a fluid bag 23, a securing means 24, a pressure tube 25 and a second set port 26. The detachable pressure sensor 21 can be a strain sensor, but is not limited thereto.

The pressure tube body 25 is a hollow gas fluid communication tube for connecting the blood pressure measuring host 10 and the fluid bag 23 of the cuff bag 20 to transfer a fluid (for example, air) from the blood pressure measuring host 10 to the fluid bag. 23, and the fluid bag 23 is inflated to be in an inflated state. In the preferred embodiment, the pressure tube body 25 is a hollow tube body made of a material (for example, rubber) that can withstand a change in the gas pressure in the tube. The manner in which the two ends of the pressure tube 25 are connected to the blood pressure measuring main body 10 and the fluid bag 23 of the cuff 20 will be described later.

The screen 11 is disposed on an upper surface 16 of the blood pressure measuring host 10 for displaying the vital signal information of the tested human body for the user to understand the physical state of the measured human body. The so-called biosignal information includes at least blood pressure information such as systolic blood pressure and diastolic blood pressure of the measured human blood pressure.

When the first connecting portion 253 of the pressure tube 25 is connected to the first assembled port 15, the signal line 255 is electrically connected to the signal receiving portion 151. Therefore, the signal of the detachable pressure sensor 21 is transmitted through the signal line 255, and enters the blood pressure measurement host 10 via the signal receiving portion 151 of the first connection port 15. Since the pressure tube body 25 and the signal line 255 share the first group connection port 15 and the second group connection port 26, it is more convenient to assemble the pressure tube 25 and the signal line 255.

Please refer to FIG. 3 and FIG. 4 together. FIG. 3 is a partial cross-sectional view of the A-A line of the cuff bag of FIG. 1, and FIG. 4 is a schematic view showing the operation of the first embodiment of the cuff bag of the present invention. As shown in FIG. 1 to FIG. 4, the covering member 22 is an object for wrapping the blood pressure measuring portion of the human body around the blood pressure measuring portion of the human body, wherein the covering member 22 is a rectangular strip made of a flexible material. Belt or ring belt. The above-mentioned human blood pressure measurement site refers to a human body part that can measure blood pressure, such as an upper limb or a lower limb. The upper arm H in the above limbs is exemplified below.

The cover member 22 includes a first cladding layer 221 and a second cladding layer 222, wherein the first cladding layer 221 and the second cladding layer 222 are respectively rectangular strips of similar sizes, and the first cladding layer The four edges of 221 are joined to the four edges of the second cladding layer 222, respectively. In the preferred embodiment, the first cladding layer 221 is bonded to the second cladding layer 222 by stitching, but is not limited thereto. Since the manner of joining the first cladding layer 221 and the second cladding layer 222 is the same as that of the prior art, no further details will be described herein. When the covering member 22 is wrapped around the upper arm H, the rectangular strip close to the arm H is the first covering layer 221, and the rectangular strip away from the upper arm H is the second cladding layer 222.

The fluid bag 23 is disposed between the first covering layer 221 and the second covering layer 222 of the covering member 22 for accommodating air from the blood pressure measuring host 10. When air enters the fluid bag 23, the fluid bag 23 begins to expand; as the air leaves the fluid bag 23, the fluid bag 23 begins to shrink.

The second set of ports 26 are disposed on one side of the cover member 22, wherein the second set of ports 26 includes two ends 261, 262. One end 261 of the second set of ports 26 is secured to the fluid bag 23, and the other end 262 of the second set of ports 26 is coupled to the pressure tube 25. The connection relationship between the fluid bladder 23, the pressure tubular body 25, and the blood pressure measuring host 10 will be described below.

The pressure tube 25 includes a first end 251 and a second end 252. The first end 251 of the pressure tube body 25 is provided with a first connecting portion 253, and the second end 252 of the pressure tube body 25 is provided with a second connecting portion 254. The first connecting portion 253 and the second connecting portion 254 can be fixed to both ends of the pressure tube 25 by adhesion, engagement, or the like, or can be integrally formed with the pressure tube 25 by injection molding. The manner of the above-mentioned connection between the first connecting portion 253, the second connecting portion 254 and the pressure tube body 25 is only one embodiment of the present invention, and is not limited thereto.

In order to connect the first end 251 of the pressure tube 25 in series with the first connection port 15 of the blood pressure measuring device 10, the appearance of the first connecting portion 253 of the pressure tube 25 will be complementary to the first shape. The shape of the first connection portion 253 of the pressure tube body 25 corresponds to the size of the first group connection port 15 .

Similarly, the outer shape of the second connecting portion 254 of the pressure tube 25 is complementary to the outer shape of the second connecting port 26 of the cuff 20, and the size of the second connecting portion 254 of the pressure tube 25 coincides with The size of the second set of ports 26 of the cuff 20 is. Therefore, the second end 252 of the pressure tube 25 will be connected in series to one end 261 of the second set port 26 in a combined manner. However, the connection between the pressure tube body 25, the blood pressure measurement host 10 and the cuff 20 is not limited to the combined connection method, and is not limited to the above-described combined connection method.

As described above, one end 261 of the second set of ports 26 is secured to the fluid bag 23 of the cuff 20 and the other end 262 is coupled to the pressure tube 25. Therefore, the fluid bag 23 is connected to the pressure tube body 25 by the second set connection port 26. When the pressurizing motor 14 delivers air to the fluid bladder 23, the fluid bladder 23 expands in an inflated state, thereby pressing the upper arm H and thereby blocking the circulation of the upper arm H arterial blood.

The fixing means 24 means means for fixing the detachable pressure sensor 21 to the covering member 22. In the preferred embodiment, the fixing means 24 can be any one of a receiving member and a devil felt. The following description will take the receiving member 24 as an example. The receiving member 24 is disposed on at least one of the first cladding layer 221 and the second cladding layer 222 and is located on at least one side of the fluid bag 23 . In the preferred embodiment of the present invention, the receiving member 24 is disposed on the first cladding layer 221 and located on the inner surface S1 of the first cladding layer 221 .

Please refer to FIG. 5 first. FIG. 5 is a schematic structural view of the first cladding layer and the accommodating member at a first angle. As shown in FIG. 5, the receiving member 24 is a rectangular sheet made of a flexible material, such as a cloth sheet or a plastic film. The accommodating member 24 includes four edges 24a, 24b, 24c, and 24d, wherein the three edges 24a, 24b, and 24c of the accommodating member 24 are fixed on the inner surface S1 of the first covering layer 221, and are in the first package. An accommodating space is formed between the cover 221 and the accommodating member 24 for accommodating the detachable pressure sensor 21. The above fixing manner may be adhesion, suturing or other common combination, but is not limited thereto.

In addition, the edge 24d not fixed to the first cladding layer 221 forms an opening 27 with the first cladding layer 221. The opening 27 is used for the detachable pressure sensor 21 to pass, and the detachable pressure sensor 21 can enter or leave the accommodating space between the first covering layer 221 and the accommodating member 24. In this way, when the covering member 22 is damaged and cannot be used, when the detachable pressure sensor 21 still maintains the normal function, the user can take out the detachable pressure sensor 21 in the old cuff bag, and then The detachable pressure sensor 21 is loaded into the new cuff bag for continued use, thereby reducing the cost of updating the blood pressure measuring device 1. Vice versa, if the detachable pressure sensor 21 is damaged and the cover member 22 still functions normally, the user can directly take out the detachable pressure sensor 21 for repair or replacement.

Next, please refer to FIG. 6. FIG. 6 is a schematic structural view of the first cladding layer and the receiving member at a second angle. As shown in FIGS. 3 and 6, the cover member 22 further includes a transparent region 223. The transparent region 223 is disposed on at least one of the first cladding layer 221 and the second cladding layer 222, and is corresponding to and adjacent to the receiving member 24 for the user to see through the transparent region 223. The detachable pressure sensor 21 of 24. In the preferred embodiment, the transparent region 223 is disposed on the first cladding layer 221 .

In order to prevent the detachable pressure sensor 21 from falling out of the accommodating member 24, or moving the position easily, the accuracy of the blood pressure measuring device 1 is lowered, and the embossed bag 20 further includes a fixing structure. 28, such as Devil's Felt 28. As shown in FIG. 3, the male devil felt 28a in the devil felt 28 is disposed on one side of the detachable pressure sensor 21, and the female devil felt 28b in the devil felt 28 is disposed on the inner side of the accommodating member 24, The detachable pressure sensor 21 is fixed in the accommodating member 24 by connecting the male devil felt 28a.

The process and principle of measuring blood pressure by the blood pressure measuring device 1 will be described below. The blood pressure measuring device 1 can be any one of an upward measuring blood pressure measuring device and a downward measuring blood pressure measuring device. Hereinafter, the blood pressure measuring device 1 is measured by a downward measuring blood pressure measuring method. For example, but not limited to this. First, as shown in FIG. 4, the cuff 20 is tightly wrapped around the upper arm H of the human subject under test, wherein the subject to be tested may be a user or other person. The detachable pressure sensor 21 is attached to the upper arm H through the first cladding layer 221 of the cuff 20 . In order to improve the accuracy of measuring blood pressure, the detachable pressure sensor 21 covers the position of the artery of the upper arm H.

When the pressurizing motor 14 is activated to start operation, the air is transferred to the fluid bag 23 of the cuff bag 20 to gradually expand the fluid bag 23, thereby blocking the blood flow of the artery in the upper arm H. When the blood flow of the upper arm H artery is completely blocked, the fluid bag 23 begins to deflate and gradually shrinks.

When the air pressure in the fluid bag 23 is reduced until the blood flow is sufficient to circulate, the arterial wall is slightly shaken by the impact of the blood. The minute vibration is transmitted to the surface of the upper arm H via internal tissues (for example, muscles), causing a deformation of the surface of the upper arm H, thereby causing an undulating change in the surface of the first cladding layer 221 of the covering member 22. The pressure sensor 21 senses the fluctuation of the first cladding layer 221 and transmits a deformation signal to the blood pressure measurement host 10. The time point at which the blood pressure measurement main unit 10 generates according to the deformation signal corresponds to the air pressure value in the blood pressure bag 20 at that time, thereby estimating the systolic blood pressure value of the blood pressure of the measured human body.

When the cuff 20 is gradually reduced and the artery is no longer compressed, the arterial blood flow can smoothly flow through the artery and is no longer subjected to blood impact. Therefore, the shape of the upper arm H no longer generates a shape variable, and the detachable pressure sensor 21 no longer transmits the deformation signal to the blood pressure measuring host 10. The blood pressure measurement main unit 10 corresponds to the air pressure value in the blood pressure bag 20 at the time when the deformation signal disappears, thereby deriving the diastolic blood pressure value of the blood pressure of the measured human body.

Further, the structure of the receiving member 24 is not limited to a rectangular sheet. In other preferred embodiments, the receiving member 24 is a pocket having an accommodating space, and the pouch is disposed on the covering member 22 by means of bonding or stitching. Furthermore, the position of the receiving member 24 is not limited to the first package. The inner surface S1 of the cladding layer 221 may also be disposed on an outer surface S2 of the first cladding layer 221, an inner surface S3 of the second cladding layer 222, or an outer surface S4 of the second cladding layer 222.
