Description

Technical Field

[0001] The present invention relates to the technical field of blood pressure measuring equipment, and in particular to a blood pressure measuring device and a method for using the same. Background Art

[0002] Blood pressure refers to the lateral pressure acting on the vessel wall per unit area when blood flows in the blood vessels. It is the driving force for promoting blood flow in the blood vessels. In different blood vessels, it is called arterial blood pressure, capillary pressure and venous blood pressure respectively. Blood pressure usually refers to the arterial blood pressure of systemic circulation. There are as many as 200 million patients with hypertension in my country, and with the increase in population and the acceleration of aging, the number of patients with hypertension will continue to increase. However, according to survey results, the awareness and control rates of hypertension in the Chinese population are relatively low. One of the important reasons is that the general public does not understand the law of blood pressure fluctuations, or the measurement method is not standardized. The person being measured should take a seat, preferably a chair with a backrest; expose the right upper arm, and place the elbow at the same level as the heart. If peripheral vascular disease is suspected, the blood pressure of both arms should be measured at the first visit. In special circumstances, blood pressure can be measured in the supine or standing position; the elderly, diabetics and those who often suffer from orthostatic hypotension should measure the standing blood pressure. The standing blood pressure measurement should be 2 minutes after the supine position is changed to the standing position. Regardless of the position of the person being measured, the sphygmomanometer should be placed at heart level.

[0003] During the inflation process of the airbag, air needs to be inhaled from the outside. The air contains moisture. When moisture enters the airbag, it may form water droplets on the inner wall of the airbag, affecting the elasticity of the airbag and the uniformity of pressure transmission. During the inflation and deflation process, the pressure changes may become unstable, resulting in deviations in the measurement results and failure to accurately reflect the true blood pressure value. Summary of the invention

[0017] Further, a drain pipe is fixedly installed on the corresponding F-shaped exhaust pipe. The right end of the drain pipe extends outside the housing.

[0018] Further, a method for a blood pressure measuring device is as follows:

[0019] S1: Filter moisture: After the air enters the circular hollow cylinder, it will contact the water-absorbing sponge. The water-absorbing sponge will filter out the moisture in the air, leaving the moisture on the water-absorbing sponge to prevent the moisture from entering the airbag strap together with the air, resulting in inaccurate detection of the airbag strap. During the rotation of the rotating shaft, the circular plate will be driven to rotate. The circular plate will drive the threaded annular block to rotate. The threaded annular block will drive the threaded annular block and the circular plate to move towards the direction close to the rectangular air box under the action of the reciprocating thread on the inner wall of the circular hollow cylinder. The circular plate drives the L-shaped round rod to move synchronously. The L-shaped round rod drives the extrusion roller to move. The extrusion roller will rotate synchronously during the movement. When the extrusion roller contacts the water-absorbing sponge, it will rotate and extrude the water-absorbing sponge to squeeze out the moisture in the water-absorbing sponge;

[0020] S2: Sealing gas: When the air pressure in the airbag strap reaches the required threshold, the pressure sensor will transmit a signal to the electric telescopic rod and the drive motor. At this time, the drive motor is turned off, and the corresponding electric telescopic rod will drive the rectangular closing plate to move in the direction close to the T-shaped plate. The rectangular closing plate will drive the rectangular contact rod to move, and the rectangular closing plate will close the L-shaped air pipe. At this time, the air in the circular hollow cylinder cannot be input into the sealed air box and the rectangular air box through the L-shaped air pipe. At this time, the limit spring will push the rectangular hollow block under the action of elastic force, and the rectangular hollow block will drive the leakage groove to leave the wider part of the sealed air box to ensure that the air pressure in the airbag strap remains unchanged;

[0021] S3: Blow out dust: When the rectangular contact rod rises, it will drive the rectangular limit rod to move toward the circular hollow cylinder, and the rectangular limit rod will drive the strip closing plate to move. When the rectangular limit rod enters the F-shaped exhaust pipe, the rectangular contact rod will contact the T-shaped plate during its rise, and the T-shaped plate will rise, causing the telescopic spring to be compressed and deformed. When the narrower part of the T-shaped plate enters the F-shaped exhaust pipe, the air in the airbag strap, the inflation tube and the rectangular air box will be discharged from the gap between the T-shaped plates into the circular hollow cylinder, and the air will be blown out of the circular hollow cylinder in the direction of the air inlet. In this process, the dust remaining in the air inlet will be blown out by the air, reducing the possibility of dust entering the circular hollow cylinder.

[0022] S4: Evaporation of moisture: When the squeezing roller squeezes the absorbent sponge, the moisture squeezed out of the absorbent sponge will flow to the inner wall of the arc-shaped bottom of the circular hollow cylinder, and enter the drain pipe along the corresponding F-shaped exhaust pipe. The moisture will be discharged from the outer shell along the drain pipe. When the airbag strap is vented, the gas will be discharged from the F-shaped exhaust pipe, the drain pipe and the circular hollow cylinder at the same time. During the flow of air, the moisture remaining in the F-shaped exhaust pipe, the drain pipe and the circular hollow cylinder will be evaporated.

[0023] The present invention has the following beneficial effects:

[0024] (1) The present invention provides a blood pressure measuring device. When in use, the airbag strap is wrapped around the patient's arm and fixed by a Velcro group. Then the driving motor is started. The driving motor drives the rotating shaft to rotate. The rotating shaft drives a plurality of dehumidification fan blades to rotate. The rotation of the dehumidification fan blades generates a suction force. The suction force sucks in the outside air through the air inlet hole and inputs it into the airbag strap from the L-shaped air pipe, the sealed air box, the rectangular air box and the inflation tube to achieve inflation. When the air passes through the sealed air box, the air pushes the rectangular hollow block into the sealed air box. At this time, the limit spring is compressed and deformed. When the leakage groove enters the wider part of the sealed air box, the air is discharged from the leakage groove into the sealed air box, and then enters the rectangular air box from the through groove on the sealed air box. After the air enters the circular hollow cylinder, it contacts the water absorption sea. The water-absorbing sponge will filter out the moisture in the air and keep the moisture on the water-absorbing sponge to prevent the moisture from entering the airbag strap along with the air, resulting in inaccurate detection of the airbag strap. During the rotation of the rotating shaft, the circular plate will be driven to rotate, and the circular plate will drive the threaded annular block to rotate. The threaded annular block will drive the threaded annular block and the circular plate to move toward the rectangular air box under the action of the reciprocating thread on the inner wall of the circular hollow cylinder. The circular plate drives the L-shaped round rod to move synchronously, and the L-shaped round rod drives the squeezing roller to move. The squeezing roller will rotate synchronously during the movement. When the squeezing roller contacts the water-absorbing sponge, it will rotate and squeeze the water-absorbing sponge to squeeze out the water in the water-absorbing sponge, ensuring that no water will enter the airbag strap during the continuous blood pressure detection of the device to affect the detection accuracy.

[0025] (2) A blood pressure measuring device of the present invention, when the air pressure in the airbag strap reaches a required threshold, the pressure sensor transmits a signal to the electric telescopic rod and the drive motor, at which time the drive motor is turned off, and the corresponding electric telescopic rod drives the rectangular closing plate to move in the direction close to the T-shaped plate, and the rectangular closing plate drives the rectangular contact rod to move, and the rectangular closing plate closes the L-shaped air tube, at which time the air in the circular hollow cylinder cannot be input into the sealed air box and the rectangular air box through the L-shaped air tube, and at this time the limit spring pushes the rectangular hollow block under the action of elastic force, and the rectangular hollow block drives the leakage groove to leave the wider part of the sealed air box, thereby ensuring that the air pressure in the airbag strap remains unchanged, so as to facilitate the effective detection of blood pressure through the pressure gauge when releasing the gas;

[0026] (3) A blood pressure measuring device of the present invention, when the rectangular contact rod rises, it will drive the rectangular limit rod to move in the direction close to the circular hollow cylinder, and the rectangular limit rod will drive the strip closing plate to move. When the rectangular limit rod enters the F-shaped exhaust pipe, the rectangular contact rod will contact the T-shaped plate during the rising process, and the T-shaped plate will rise, and the telescopic spring will be compressed and deformed. When the narrower part of the T-shaped plate enters the F-shaped exhaust pipe, the air in the airbag strap, the inflation tube and the rectangular air box will be discharged into the circular hollow cylinder from the gap between the T-shaped plates, and the air will be blown out of the circular hollow cylinder in the direction of the air inlet. In this process, the dust remaining in the air inlet will be blown out by the air, reducing the possibility of dust entering the circular hollow cylinder. When the rotating shaft rotates, it will drive the dust removal plate to rotate, and the dust removal plate will also clean the dust on the wall of the air inlet, reducing the possibility of dust accumulation and avoiding the problem of blockage affecting the inflation effect.

[0027] (4) The present invention provides a blood pressure measuring device. When the squeezing roller squeezes the water-absorbing sponge, the water squeezed out of the water-absorbing sponge will flow onto the inner wall of the arc-shaped bottom of the circular hollow tube and enter the drain pipe along the corresponding F-shaped exhaust pipe. The water will be discharged from the outer shell along the drain pipe. When the airbag strap is exhausted, the gas will be discharged from the F-shaped exhaust pipe, the drain pipe and the circular hollow tube at the same time. During the flow of air, the water remaining in the F-shaped exhaust pipe, the drain pipe and the circular hollow tube will be evaporated, so that the water can be quickly discharged from the device, thereby preventing the residual water from affecting the detection result.

[0028] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figure 1 - Figure 8 As shown, the present invention is a blood pressure measurement device, including an outer shell 1. A circular hollow cylinder 2 is fixedly installed inside the blood pressure measurement outer shell 1. The right side of the blood pressure measurement circular hollow cylinder 2 extends outside the outer shell 1. A rotating shaft 3 is rotatably installed inside the blood pressure measurement circular hollow cylinder 2. A driving motor 4 is fixedly installed on the left inner wall of the blood pressure measurement outer shell 1. The output shaft of the blood pressure measurement driving motor 4 is fixedly connected to the rotating shaft 3. It further includes:

[0042] Dehumidification mechanism 5, blood pressure measurement The dehumidification mechanism 5 includes a rectangular slot 504, a rotating component, and a blood pressure measurement rectangular slot 504 for driving the rotating component to rotate, a movable component, and a blood pressure measurement rectangular slot 504 for driving the movable component to slide;

[0043] The blood pressure measurement rotating assembly includes a plurality of dehumidification blades 501 fixedly mounted on the rotating shaft 3, a circular filter plate 502 and a water-absorbing sponge 503 are rotatably sleeved on the blood pressure measurement rotating shaft 3, the blood pressure measurement circular filter plate 502 and the water-absorbing sponge 503 are fixedly connected, the outer wall of the blood pressure measurement water-absorbing sponge 503 is fixedly connected to the circular hollow cylinder 2, and a circular plate 505 is sleeved on the blood pressure measurement rectangular groove 504;

[0044] The blood pressure measurement movable component includes a threaded annular block 506 fixedly mounted on the outer wall of a circular plate 505. The outer wall of the blood pressure measurement threaded annular block 506 is threadedly connected to the circular hollow cylinder 2. Two L-shaped round rods 507 are fixedly mounted on the left side of the blood pressure measurement circular plate 505. Extrusion rollers 508 are respectively rotatably sleeved on the two blood pressure measurement L-shaped round rods 507.

[0045] like Figure 4 As shown, a plurality of air inlet holes 509 are opened on the right side of the circular hollow cylinder 2, the right end of the blood pressure measuring rotating shaft 3 extends outside the circular hollow cylinder 2, and a dust removal plate 510 is fixedly installed on the outer wall of the blood pressure measuring rotating shaft 3, and the left end of the blood pressure measuring dust removal plate 510 is in contact with the circular hollow cylinder 2.

[0046] The air will be blown out of the circular hollow cylinder 2 in the direction of the air inlet hole 509 from the inside of the circular hollow cylinder 2. During this process, the dust remaining in the air inlet hole 509 will be blown out by the air, reducing the possibility of dust entering the circular hollow cylinder 2. When the rotating shaft 3 rotates, the dust removal plate 510 will be driven to rotate. The dust removal plate 510 will also clean the dust on the wall of the air inlet hole 509, reducing the possibility of dust accumulation and avoiding blockage problems that affect the inflation effect.

[0047] like Figure 6 As shown, an inflation mechanism 6 is provided in the outer shell 1, and the blood pressure measuring inflation mechanism 6 includes a rectangular air box 601 fixedly installed in the outer shell 1, and the blood pressure measuring rotating shaft 3 rotates and penetrates the rectangular air box 601, and two sealed air boxes 602 are fixedly installed on the right end of the blood pressure measuring rectangular air box 601, and the left ends of the two blood pressure measuring sealed air boxes 602 extend into the rectangular air box 601, and an L-shaped air pipe 603 is fixedly installed on the left side of the blood pressure measuring circular hollow cylinder 2, and the left ends of the two blood pressure measuring L-shaped air pipes 603 are respectively fixedly connected to the two sealed air boxes 602.

[0048] The rotating shaft 3 drives several dehumidifying fan blades 501 to rotate. The rotation of the dehumidifying fan blades 501 generates a suction force. The suction force sucks in the outside air through the air inlet holes 509 and inputs it into the airbag strap 605 through the L-shaped air pipe 603, the sealed air box 602, the rectangular air box 601, and the charging air pipe 604 to achieve inflation.

[0049] As Figure 2 shown, a charging air pipe 604 is fixedly installed at the left end of the rectangular air box 601. The left end of the blood pressure measurement charging air pipe 604 extends outside the housing 1. The left end of the blood pressure measurement charging air pipe 604 is fixedly installed with an airbag strap 605. A pressure sensor 606 and a pressure gauge 607 are fixedly installed inside the blood pressure measurement airbag strap 605. A magic tape group 608 is arranged on the blood pressure measurement airbag strap 605.

[0050] After the air enters the circular hollow cylinder 2, it will come into contact with the water-absorbing sponge 503. The water-absorbing sponge 503 will filter out the moisture in the air, leaving the moisture on the water-absorbing sponge 503 to prevent the moisture from entering the airbag strap 605 together with the air and causing inaccurate detection of the airbag strap 605.

[0051] As Figure 6 shown, the inflation mechanism 6 further includes a sealing component arranged on the two sealed air boxes 602. The blood pressure measurement sealing component includes a through groove 609 opened on the sealed air box 602. A limit spring 610 is fixedly installed on the left inner wall of the blood pressure measurement sealed air box 602. The right end of the blood pressure measurement limit spring 610 is fixedly installed with a rectangular hollow block 611. A number of leakage grooves 612 are opened on the outer wall of the blood pressure measurement rectangular hollow block 611. The blood pressure measurement rectangular hollow block 611 is slidably connected to the sealed air box 602.

[0052] The rectangular hollow block 611 will drive the leakage grooves 612 away from the wider part of the sealed air box 602 to ensure that the air pressure inside the airbag strap 605 remains unchanged, facilitating the effective detection of blood pressure by the pressure gauge 607 when releasing the gas.

[0053] As Figure 7 shown, closing mechanisms 7 are respectively arranged on the two blood pressure measurement L-shaped air pipes 603. The blood pressure measurement closing mechanism 7 includes an F-shaped exhaust pipe 701 fixedly installed on the top of the L-shaped air pipe 603. The left end of the blood pressure measurement F-shaped exhaust pipe 701 communicates with the rectangular air box 601. The right end of the blood pressure measurement F-shaped exhaust pipe 701 communicates with the circular hollow cylinder 2. The top of the blood pressure measurement F-shaped exhaust pipe 701 is fixedly installed with a C-shaped frame 702. A telescopic spring 703 is fixedly installed on the inner wall of the top of the blood pressure measurement C-shaped frame 702. The bottom end of the blood pressure measurement telescopic spring 703 is fixedly installed with a T-shaped plate 704. The blood pressure measurement T-shaped plate 704 penetrates through the F-shaped exhaust pipe 701 and is slidably connected to the F-shaped exhaust pipe 701.

[0054] The T-shaped plate 704 will rise and the telescopic spring 703 will be compressed and deformed. When the narrower part of the T-shaped plate 704 enters the F-shaped exhaust pipe 701, the air in the airbag strap 605, the inflation tube 604 and the rectangular air box 601 will be discharged into the circular hollow tube 2 from the gap between the T-shaped plates 704 and 704.

[0055] like Figure 3 and Figure 7 As shown, the closing mechanism 7 also includes two lifting assemblies fixedly installed on the left side of the circular hollow cylinder 2, and the blood pressure measurement lifting assembly includes a mounting plate 705 fixedly installed on the left side of the circular hollow cylinder 2, and an electric telescopic rod 706 is fixedly installed on the top of the blood pressure measurement mounting plate 705, and a rectangular closing plate 707 is fixedly installed on the output shaft of the blood pressure measurement electric telescopic rod 706, and the top end of the blood pressure measurement rectangular closing plate 707 slides and extends into the F-shaped exhaust pipe 701, and a rectangular contact rod 708 is fixedly installed on the top of the blood pressure measurement rectangular closing plate 707, and the top end of the blood pressure measurement rectangular contact rod 708 slides and extends outside the F-shaped exhaust pipe 701.

[0056] When the air pressure in the airbag strap 605 reaches the required threshold, the pressure sensor 606 will transmit a signal to the electric telescopic rod 706 and the drive motor 4. At this time, the drive motor 4 is turned off, and the corresponding electric telescopic rod 706 will drive the rectangular closing plate 707 to move toward the direction close to the T-shaped plate 704, and the rectangular closing plate 707 will drive the rectangular contact rod 708 to move.

[0057] like Figure 7 As shown, the closing mechanism 7 also includes a limiting assembly arranged on two rectangular contact rods 708, and the blood pressure measurement limiting assembly includes a connecting rod 709 hingedly installed on the top of the rectangular contact rod 708. The blood pressure measurement F-shaped exhaust pipe 701 is penetrated by a strip closing plate 710 that is slidably installed, and a rectangular limiting rod 711 is fixedly installed on the left end of the blood pressure measurement strip closing plate 710. The left end of the blood pressure measurement rectangular limiting rod 711 extends to the outside of the F-shaped exhaust pipe 701, and the left end of the blood pressure measurement rectangular limiting rod 711 is hinged to the rectangular contact rod 708.

[0058] When the rectangular contact rod 708 rises, it will drive the rectangular limiting rod 711 to move toward the direction close to the circular hollow cylinder 2, and the rectangular limiting rod 711 will drive the strip closing plate 710 to move. When the rectangular limiting rod 711 enters the F-shaped exhaust pipe 701, it will contact the T-shaped plate 704 during the rising process of the rectangular contact rod 708, and the T-shaped plate 704 will rise.

[0059] like Figure 2 and Figure 4 As shown, a drain pipe 712 is fixedly installed on the corresponding blood pressure measurement F-shaped exhaust pipe 701, and the right end of the blood pressure measurement drain pipe 712 extends to the outside of the housing 1.

[0060] The water squeezed out from the absorbent sponge 503 will flow to the inner wall of the curved bottom of the circular hollow tube 2, and enter the drain pipe 712 along the corresponding F-shaped exhaust pipe 701. The water will be discharged from the outer shell 1 along the drain pipe 712. When the airbag strap 605 is exhausted, the gas will be discharged from the F-shaped exhaust pipe 701, the drain pipe 712 and the circular hollow tube 2 at the same time. During the flow of air, the water remaining in the F-shaped exhaust pipe 701, the drain pipe 712 and the circular hollow tube 2 will be evaporated, so that the water can be quickly discharged from the device to avoid the influence of residual water on the detection results.

[0061] like Figure 1 - Figure 8 As shown, a method of a blood pressure measuring device, the method steps are as follows:

[0062] S1: Filtering moisture: After the air enters the circular hollow cylinder 2, it will contact the water-absorbing sponge 503. The water-absorbing sponge 503 will filter out the moisture in the air and leave the moisture on the water-absorbing sponge 503 to prevent the moisture from entering the airbag strap 605 along with the air, resulting in inaccurate detection of the airbag strap 605. During the rotation of the rotating shaft 3, the circular plate 505 will be driven to rotate, and the circular plate 505 will drive the threaded annular block 506 to rotate. The threaded annular block 506 will drive the threaded annular block 506 and the circular plate 505 to move toward the rectangular air box 601 under the action of the reciprocating thread on the inner wall of the circular hollow cylinder 2. The circular plate 505 drives the L-shaped round rod 507 to move synchronously, and the L-shaped round rod 507 drives the squeezing roller 508 to move.
