Fig. 2 is a schematic structural view of an exemplary embodiment of a sphygmomanometer cuff disposed around an upper arm. Fig. 3 is a schematic structural diagram of an exemplary embodiment when components in the sphygmomanometer host are connected with the air bag.
A sphygmomanometer, which is worn around an upper arm to be measured (refer to fig. 2), comprises a cuff 1 and a host machine 2 (refer to fig. 1), as shown in fig. 1, the cuff 1 comprises a housing 11 and an inflatable and contractible air bag 12, the air bag 12 is fixed by being attached to the inner side of the housing 11, namely when the cuff 1 is worn around the upper arm, the air bag 12 is positioned at one side of the housing 11 close to the skin; the main unit 2 is fixed to the cuff 1, and the main unit 2 includes a pump unit 21 for inflating the airbag 12, a valve unit 22 for deflating the airbag 12, and a pressure sensing unit 23 for sensing the internal pressure of the airbag 12 (see fig. 3).
As shown in fig. 1 and 3, an air inlet hole 121 connected to the pump unit 21, an air outlet hole 122 connected to the valve unit 22, and a monitoring hole 123 connected to the pressure sensing unit 23 are disposed on one side of the air bag 12 connected to the host 2, the air inlet hole 121, the air outlet hole 122, and the monitoring hole 123 are communicated with the internal cavity of the air bag 12 (refer to fig. 3), as shown in fig. 1, the air inlet hole 121, the air outlet hole 122, and the monitoring hole 123 are disposed at intervals on the air bag 12 along the width direction of the cuff 1, the air inlet hole 121 is disposed on one side of the air outlet hole 122, the monitoring hole 123 is disposed on the other side of the air outlet hole 122, that is, as shown in fig. 1, the air inlet hole 121, the air outlet hole 122, and the monitoring hole 123 are disposed on the air bag 12 from top to bottom, and the air inlet hole 121, and the monitoring hole 123 are respectively disposed on two sides of the air outlet hole 122. When the blood pressure flows, pulse waves are generated, so that the gas in the air bag 12 fluctuates, the sphygmomanometer senses the gas fluctuation in the air bag 12 through the pressure sensing unit 23 to indirectly acquire the pulse waves, and the blood pressure information in the blood vessel is indirectly acquired through the conversion of the circuit. In the process that the pump unit 21 inflates the air bag 12 through the air inlet hole 121, the pressure sensing unit 23 monitors the air pressure in the air bag through the monitoring hole 123, so that when the blood pressure is measured indirectly, the air entering the air bag 12 through the air inlet hole 121 causes the air at the monitoring hole 123 to fluctuate, the blood pressure information acquired by the pressure sensing unit 23 has a large error, and the accuracy of the information acquired by the pressure sensing unit 23 is influenced. The sphygmomanometer is arranged on the air bag 12 at intervals along the width direction of the cuff 1 through the air inlet hole 121, the air outlet hole 122 and the monitoring hole 123, the distance between the air inlet hole 121 and the monitoring hole 123 in the width direction of the cuff 1 is increased, the influence of air entering through the air inlet hole 121 on the air at the monitoring hole 123 is reduced, and therefore the accuracy of the blood pressure information acquired by the pressure sensing unit 23 is improved.
When the cuff 1 of the sphygmomanometer is worn around the upper arm along the length direction, the air inlet hole 121, the air outlet hole 122 and the monitoring hole 123 are arranged along the direction from the proximal end of the upper arm to the distal end (as shown in fig. 2), so that the air inlet hole 121, the air outlet hole 122 and the monitoring hole 123 can be arranged along the extending direction of the upper arm, part of brachial artery at the upper arm is covered by biceps brachii muscle due to the physiological structure, and part of brachial artery at the elbow of the upper arm is not covered by muscle, so that more accurate blood pressure data can be obtained by monitoring at the position. The air inlet hole 121, the air outlet hole 122 and the monitoring hole 123 on the sphygmomanometer cuff 1 are arranged along the direction from the proximal end of the upper arm to the distal end, so that the monitoring hole 123 is positioned at the brachial artery which is not covered by muscle, and the pressure sensing unit 23 can monitor the blood pressure more accurately through the monitoring hole 123. Referring to fig. 2 and 4, when the cuff 1 is placed around the upper arm, the air bag 12 has a width direction extending in the axial direction of the cuff 1, that is, the width direction of the air bag 12 is the same as the width direction of the cuff 1, and preferably, the distance between the monitor hole 123 and the edge of the air bag 12 near the distal end is the width of the air bag 12
To
The pressure sensing unit 23 can measure the brachial artery at the far end, and more accurate blood pressure data can be obtained; preferably, if the blood pressure information is obtained during inflation, in order to make the gas data in the air bag 12 obtained by the pressure sensing unit 23 through the monitoring hole 123 more accurate, the air inlet hole 121 is located at the proximal end of the upper arm in the wearing state of the sphygmomanometer, and the distance between the air inlet hole 121 and the proximal end edge of the air bag 12 along the width direction of the cuff 1 is the width of the air bag 12
To
The air inlet hole 121, the air outlet hole 122 and the monitoring hole 123 are arranged along the direction of the proximal end of the upper arm pointing to the distal end, so that the monitoring hole 123 can be prevented from being bent when being worn, and the monitoring hole 123 is separated from the correct measuring position, thereby affecting the accuracy of the pressure sensing unit 23 in measuring blood pressure. The inlet hole 121 is located one side of venthole 122, monitoring hole 123 is located the opposite side of venthole 122, thereby make between inlet hole 121 and the monitoring hole 123 by venthole 122 interval, thereby further reduce pump unit 21 and aerify gasbag 12 through inlet hole 121, and when using pressure sensing unit 23 to measure the pressure in the gasbag 12 through monitoring hole 123, the gas near inlet hole 121 is to the gaseous interference near monitoring hole 123, reduce the interference fluctuation that comes from inlet hole 121 of monitoring hole 123 department, thereby obtain better monitoring result.
As shown in fig. 3, the sphygmomanometer further comprises a ventilation assembly, the air inlet 121, the air outlet 122 and the monitoring hole 123 are respectively connected with the pump unit 21, the valve unit 22 and the pressure sensing unit 23 through a main unit air tap 201 of the air bag air tap 124 in a direct-insertion manner, so that the length of a connecting pipeline between the main unit 2 and the air bag 12 is reduced, the situations that the connecting pipeline between the air bag 12 and the pressure sensing unit 23 of the traditional sphygmomanometer is too long and the fluctuation of the air obtained by the pressure sensing unit 23 is small are avoided, and therefore the main unit 2 is connected with the air bag 12 in a direct-insertion manner, the monitoring precision of the sphygmomanometer can be improved, and the accuracy of the obtained blood pressure data is ensured; meanwhile, the assembly difficulty can be reduced by the direct-insertion connection mode, the assembly efficiency is improved, the process is simplified, and the production efficiency is improved; meanwhile, due to the positions of the air inlet hole 121, the air outlet hole 122 and the monitoring hole 123, when the host machine 2 is connected with the air bag 12 in a straight insertion manner, the pump unit 21, the valve unit 22 and the pressure sensing unit 23 in the host machine 2 can be arranged more reasonably and arranged along the width direction of the cuff 1 as much as possible, the arrangement of the host machine in the length direction of the cuff 1 is reduced, when the cuff 1 is bound on the upper arm, the compression of the host machine 2 on the cuff 1 can be reduced, and the measurement error is reduced.
Those skilled in the art can understand that the connection mode of the host 2 and the airbag 12 is not limited to the above-mentioned matching mode of the host air nozzle 201 and the airbag air nozzle 124, but other modes can be used, such as the host air nozzle 201 and the airbag air nozzle 124 are connected through the insertion pipe, and two ends of the insertion pipe are respectively connected with the host air nozzle 201 and the airbag air nozzle 124, so that the host 2 and the airbag 12 are connected in a straight-inserting manner, and the fault tolerance can be improved by using the mode that two ends of the insertion pipe are respectively connected with the host air nozzle 201 and the airbag air nozzle 124, for example, in the manufacturing process, there is a small dislocation between the host air nozzle 201 and the airbag air nozzle 124, and the host 2 and the airbag 12 can be connected in a straight-inserting manner through the insertion pipe respectively connected with the host air nozzle 201 and the airbag air nozzle 124, and the connection tightness can also be ensured, the situation that the pressure sensing unit 23 cannot acquire accurate blood pressure information due to gas fluctuation caused by non-pulse of gas in the air bag 12 caused by gas leakage is avoided.
As shown in fig. 3, the vent assembly includes air bag nozzles 124 parallel to each other and respectively disposed on the air bag 12 corresponding to the air inlet hole 121, the air outlet hole 122, and the monitoring hole 123, the main unit 2 further includes a bottom case 24 and a cover case 25 forming an installation cavity, the pump unit 21, the valve unit 22, and the pressure sensing unit 23 are fixed in the installation cavity, and the bottom case 24 is provided with a through hole 202 for inserting the air bag nozzles 124.
The parallel air bag air nozzles 124 are respectively arranged on the air bag 12 corresponding to the air inlet hole 121, the air outlet hole 122 and the monitoring hole 123, and the air bag air nozzles 124 are clearly aligned when being directly connected with the main machine air nozzle 201, so that the installation is more convenient. The bottom case 24 is provided with a through hole 202 for inserting the air nozzle 124, when the air nozzle 124 is directly connected with the host air nozzle 201, the bottom case 24 can be fixed to the cuff 1, so that the assembly of the bottom case 24 and the cover case 25 is fixed to the cuff 1, and the pump unit 21, the valve unit 22 and the pressure sensing unit 23 are fixed to the installation cavity formed by the bottom case 24 and the cover case 25, so that the host 2 can be fixed to the cuff 1, the process of fixing the host 2 to the cuff 1 is reduced, and the production efficiency can be improved.
As shown in fig. 2 and 4, when the sphygmomanometer is worn,the surrounding direction of the cuff 1 is defined as the length direction of the air cell 12, and the length of the air cell 12 is L1(refer to fig. 4), the distance of the main body 2 from one end of the airbag 12 in the length direction of the airbag 12 is L2，0.15L1≤L2≤0.3L1. For an accurate description of the present embodiment, refer to FIG. 4, L2The distance of the main body 2 from the a side of the airbag 12, the a side shown in the drawing does not represent the a side having the airbag 12 shown in fig. 4 in the actual product, and the a side of the airbag 12 is merely used to better describe the present embodiment. In this way, the two ends of the cuff 1 are left with enough space to be connected to each other.
As shown in fig. 5, the main unit 2 of the sphygmomanometer has an elongated main unit housing, and the pump unit 21, the valve unit 22, and the pressure sensing unit 23 are provided in an internal cavity of the main unit housing. The long-strip-shaped host shell enables a user to consciously place the host 2 at the biceps brachii when the cuff is used, so that the cuff 1 is located at a correct binding position, and monitoring precision is improved. By the way that the host machine 2 is provided with the long-strip-shaped host machine shell, when a user surrounds the cuff 1 on the upper arm, the width of the host machine 2 cannot interfere with the winding of the cuff 1, so that the situation that when the cuff 1 is wound on the upper arm, the host machine 2 extrudes the air bag 12 in the cuff 1 due to the fact that the width of the host machine 2 is too large, the air pressure in the air bag 12 is influenced, and the measurement is influenced is avoided. Preferably, the width direction of the cuff 1 is parallel to the length direction of the main machine shell, and the width of the main machine 2 is D1The length of the cuff 1 is D2，
