Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 4, the electronic sphygmomanometer as shown in the figures includes a base 20 and an arm cylinder 10 disposed on the base 20, the arm cylinder 10 includes an upper cylinder cover 11 and a lower cylinder cover 12, one side edge of the upper cylinder cover 11 is rotatably connected with one side edge of the lower cylinder cover 12 through a first rotating shaft 13, the lower cylinder cover 12 is fixed on the base 20, and a passage for extending into an upper arm is formed between the upper cylinder cover 11 and the lower cylinder cover 12; the arm cylinder 10 further comprises a first detection air bag ring 14, an arm bag 15 and a second detection air bag ring 16 which are sequentially arranged in the channel along the axial direction; the electronic sphygmomanometer further comprises a host 30 connected with the base 20, wherein the host 30 comprises a control mainboard 31; the base 20 includes a driving mechanism for driving the upper cylinder housing 11 to rotate relative to the lower cylinder housing 12.
Specifically, the base 20 of the electronic sphygmomanometer is used for being placed on a platform, such as a desktop; the front end of the arm cylinder 10 of the electronic sphygmomanometer is provided with a first detection air bag ring 14, the corresponding position of the first detection air bag ring is a position of an upper arm close to the shoulder, the rear end of the arm cylinder 10 of the electronic sphygmomanometer is provided with a second detection air bag ring 16, the corresponding position of the second detection air bag ring is a position of the upper arm close to the forearm; the arm tube 10 of the electronic sphygmomanometer is provided with an arm bag 15 in the middle for measuring blood pressure, and the arm bag is positioned between a first detection air bag ring 14 and a second detection air bag ring 16. Since the arm bladder 15 for measuring blood pressure is located at a position that does not facilitate the arrangement of the sensing part for measuring the arm circumference, the embodiment of the present application can only arrange the sensing bladder rings at the ends and estimate the arm circumference at the middle position by arranging one sensing bladder (i.e., the first sensing bladder ring 14 and the second sensing bladder ring 16) at each of the ends.
In this embodiment, the first pressure sensor 142 is disposed inside the first detection airbag ring 14, and is used for measuring a real-time air pressure value inside the first detection airbag ring 14; a second pressure sensor 162 is provided inside the second detection balloon ring 16 for measuring a real-time air pressure value inside the second detection balloon ring 16. It should be noted that the real-time air pressure values inside the first detection airbag ring 14 and the second detection airbag ring 16 can reflect the degree of whether the real-time air pressure values contact with or press the upper arm, and the inflated inner diameter can be calculated according to the inflation amount reaching the real-time air pressure values, so as to calculate the arm circumference value of the upper arm.
In this embodiment, a gap is formed between the other side edge of the upper casing 11 and the other side edge of the lower casing 12, and in general, the upper casing 11 and the lower casing 12 have a C-shaped cross section, and the C-shaped opening is the gap. A portion of the first detection balloon ring 14, the arm balloon 15 and the second detection balloon ring 16 extend from the space and form separate inflation ports at the respective distal ends. Further, a first air pump interface 25, a second air pump interface 26 and a third air pump interface 27 are disposed on a side surface of the base 20, the first air pump interface 25 is used for connecting with the inflation port 141 of the first detection air bag ring 14, the second air pump interface 26 is used for connecting with the inflation port 151 of the arm air bag 15, and the third air pump interface 27 is used for connecting with the inflation port 161 of the second detection air bag ring 16. Correspondingly, the external air pump device 40 is provided with three air inflation tubes, which are respectively inserted into the first air pump connector 25, the second air pump connector 26 and the third air pump connector 27, and further communicated with the first detection air bag ring 14, the arm air bag 15 and the second detection air bag ring 16. It is to be noted that the first detection balloon ring 14, the arm bag 15 and the second detection balloon ring 16 are extended out of a part of the arm tube, and are set in a relaxed state in advance, so that a sufficient margin length can be stretched when increasing the inner diameter of the arm tube 10. Optionally, the air pump device 40 may be a single pump, and three inflation tubes are led out through a branching unit, wherein the branching unit can independently inflate and deflate the first detection balloon ring 14, the arm balloon 15 and the second detection balloon ring 16; the air pump device 40 can also be a double pump, wherein one pump leads out one inflation tube to be connected to the arm bag 15, and the other pump leads out two inflation tubes through a branching unit, wherein the branching unit can realize independent inflation and deflation of the first detection air bag ring 14 and the second detection air bag ring 16; the air pump device 40 can also be three pumps, each of which leads out an inflation tube to independently inflate and deflate the first detection airbag ring 14, the arm airbag 15 and the second detection airbag ring 16.
In this embodiment, the top surface of the base 20 is provided with at least one key 28 for obtaining an operation instruction input by the patient; in addition, the control main board 31 of the main unit 30 is electrically connected to the driving mechanism, the first pressure sensor 142, the second detection airbag ring 16, the key 28, and the external air pump device 40, respectively, through internal or external wiring connection.
Specifically, the control main board 31 measures the arm circumference value of the upper arm through the first detection airbag ring 14 and the second detection airbag ring 16; then obtaining a target inner diameter corresponding to the arm circumference value; the upper cylinder cover 11 is then controlled by the driving mechanism to rotate relative to the lower cylinder cover 12 to adjust the inner diameter of the arm cylinder 10 to a target inner diameter. In the specific implementation, the patient puts the upper arm into the arm cylinder 10, clicks the blood pressure measurement key, the control main board 31 inflates and swells the first detection airbag ring 14 and the second detection airbag through the air pump device 40 after obtaining the instruction transmitted by the key 28 until two ends of the upper arm are squeezed, at this time, the first pressure sensor 142 and the second pressure sensor 162 detect that the internal air pressure reaches the preset standard respectively, the control main board 31 is notified, the control main board 31 immediately controls the air pump device 40 to stop inflating and queries the data corresponding to the current inflation amount, the data is the arm circumference value stored in advance, for example, the arm circumference value corresponding to the inflation amount of 60ml is queried to be 28cm, the arm circumference value corresponding to the inflation amount of 68ml is queried to be 32cm, the control main board 31 then finds the arm circumference value L of the corresponding position measured by the first detection airbag ring 14 and the second detection airbag ring 16 by the preset arm circumference algorithm, and inquiring the target inner diameter corresponding to the arm circumference value L, and finally changing the size of a channel between the upper cylinder cover 11 and the lower cylinder cover 12 by controlling the driving mechanism. After the arm circumference value L is measured, the first detection balloon ring 14 and the second detection balloon 16 are deflated to avoid affecting the subsequent blood pressure measurement.
Optionally, the preset circumference algorithm is that L ═ L1 × (j + L2 ×/(j + k)), j and k are positive coefficients, where L1 is the circumference value of the corresponding position measured by the first detection airbag ring 14, and L2 is the circumference value of the corresponding position measured by the second detection airbag ring 16. In this embodiment, the part of the arm bladder 15 for measuring blood pressure is the middle-upper part of the upper arm, so the measurement result is more accurate, and correspondingly, the obtained arm circumference value L should also be the middle-upper part of the upper arm, so j > k is taken. Preferably, when j is 0.62 and k is 0.38, for example, if the arm circumference value L1 measured by the first detection balloon ring 14 is 26.5cm and the arm circumference value L2 measured by the second detection balloon ring 16 is 23.2cm, the arm circumference value L of the upper arm is 25.25cm by a preset arm circumference algorithm (26.5cm 0.62+23.2cm 0.38)/(0.62+ 0.38).
Referring to fig. 2, the driving mechanism of the electronic sphygmomanometer includes a first motor 21 and a second rotating shaft 22, where the first motor 21 is used to drive the second rotating shaft 22 to rotate, and the second rotating shaft 22 is arranged side by side with the first rotating shaft 13, where the side by side arrangement means that the rotation axis of the first rotating shaft 13 is parallel to the rotation axis of the second rotating shaft 22, and in addition, the lengths of the first rotating shaft 13 and the second rotating shaft 22 are not limited, and may be equal or different.
Further, the first rotating shaft 13 is fixed on the lower cover cylinder, and a sleeve 17 sleeved on the first rotating shaft 13 is fixedly arranged on the upper cover cylinder 11; the sleeve 17 is provided with axial tooth grooves on the outer circumferential surface thereof, and the second rotating shaft 22 is provided with tooth sleeves 221 on the outer circumferential surface thereof, which are engaged with the tooth grooves. That is, when the first motor 21 drives the second rotating shaft 22 to rotate, the gear sleeve 221 on the outer peripheral surface of the second rotating shaft 22 drives the sleeve 17 of the first rotating shaft 13 to rotate, and then the sleeve 17 drives the upper cylinder cover 11 to open or close relative to the lower cylinder cover, thereby changing the size of the passage between the upper cylinder cover 11 and the lower cylinder cover 12.
Referring to fig. 2, the driving mechanism of the electronic sphygmomanometer further includes a second motor 23 and a third rotating shaft 24, and the second motor 23 is used for driving the third rotating shaft 24 to rotate. The third rotating shaft 24 is arranged side by side with the arm cylinder 10 and is in close contact with a part of the first detection airbag ring 14, the arm airbag 15, and the second detection airbag ring 16 extending out, wherein the side by side arrangement means that the rotation axis of the third rotating shaft 24 is parallel to the central axis of the arm cylinder 10 (or the rotation axis of the first rotating shaft 13), and in addition, the length of the third rotating shaft 24 is not limited in this embodiment.
Further, the third rotating shaft 24 is used for reciprocally driving the first detection airbag ring 14, the arm airbag 15 and the second detection airbag ring 16. That is, when the upper cover 11 is opened or closed with respect to the lower cover, the first detection airbag loop 14, the arm bag 15, and the second detection airbag loop 16 need to be driven to and fro in order to avoid tension irregularity or wrinkle distortion. In a specific implementation, when the upper barrel cover 11 is opened relative to the lower barrel cover, the third rotating shaft 24 synchronously conveys part of the first detection air bag ring 14, the arm bag 15 and the second detection air bag ring 16 into the arm barrel 10; when the upper housing 11 is closed with respect to the lower housing tube, the third rotary shaft 24 synchronously transfers part of the first detection airbag loop 14, the arm bag 15, and the second detection airbag loop 16 out of the arm tube 10.
Optionally, the driving mechanism of the electronic sphygmomanometer further includes a first rubber sleeve 241, a second rubber sleeve 242 and a third rubber sleeve 243 which are sleeved on the third rotating shaft 24; the first rubber sleeve 241 is in close contact with a part of the first detection air bag ring 14 extending out, and is used for driving the first detection air bag ring 14 in a reciprocating manner; the second rubber sleeve 242 is in close contact with a part of the arm bladder 15 extending out, and is used for driving the arm bladder 15 in a reciprocating manner; the third rubber sleeve 243 is in close contact with a portion of the second detection airbag ring 16 from which it extends, for reciprocally driving the second detection airbag ring 16. It should be understood that the first rubber sleeve 241, the second rubber sleeve 242 and the third rubber sleeve 243 can enhance the friction force, avoid the transmission slip, i.e. avoid the third rotating shaft 24 from idling, and improve the reliability in changing the inner diameter of the arm cylinder 10.
In this embodiment, the first motor 21 and the second motor 23 are preferably step motors, and it should be understood that the step motors have the advantages of large torque and high precision, the large torque can provide large torsional force to realize driving, and the high precision can realize accurate driving to avoid a drop error, thereby improving the reliability in the process of changing the inner diameter of the arm cylinder 10 and improving the measurement precision.
Correspondingly, referring to fig. 4, the control main board 31 is electrically connected to the first motor 21 and the second motor 23 respectively, and is configured to drive the first motor 21 and the second motor 23 to rotate forward or backward by a specified degree.
It should be noted that the first motor 21 drives the second rotating shaft 22 and the second motor 23 drives the third rotating shaft 24 in various ways, such as the output shaft of the motor is directly connected to the rotating shaft, but this way has the disadvantage of affecting the overall size of the electronic sphygmomanometer, resulting in a longer length, and if the output shaft of the motor is connected to the rotating shaft through a planetary gear set, this way has the disadvantage of occupying a large internal space, using many components, and increasing the cost. In this embodiment, the driving mechanism further includes a first transmission belt 211 and a second transmission belt 231, the output shaft of the first motor 21 is in transmission connection with the second rotating shaft 22 through the first transmission belt 211, and the output shaft of the second motor 23 is in transmission connection with the third rotating shaft 24 through the second transmission belt 231. Of course, the strap may be replaced by a hinge, and the equivalent technical means are not exhaustive.

Optionally, the display screen 32 may be a touch display screen for obtaining an operation instruction input by the user.
