Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical devices, and particularly relates to a table type electronic sphygmomanometer. BACKGROUND

[0002] The sphygmomanometer is a medical device for measuring the blood pressure of a patient, which can help medical staff to evaluate the cardiovascular health condition of the patient by detecting the pressure (systolic pressure and diastolic pressure) generated by the blood flowing in the blood vessel to the blood vessel wall. Common sphygmomanometers can be two kinds, one of which is a mercury sphygmomanometer (mercury column type), which can accurately measure the blood pressure by auscultation, that is, the Korotkoff sound (blood vessel pulsation sound) is captured by a stethoscope to measure the blood pressure of the patient; the other is an electronic sphygmomanometer, which can calculate the blood pressure by oscillography, that is, by analyzing the pressure fluctuation of the air pressure in the cuff to calculate the blood pressure; compared with oscillography, auscultation has the advantage of high measurement accuracy, and therefore is called the clinical "gold standard".

[0003] Due to the restriction of mercury-containing products in various countries, the mercury sphygmomanometer is gradually being replaced by the electronic sphygmomanometer. In order to improve the accuracy of blood pressure detection, it is conceivable to integrate the auscultation detection function on the basis of the traditional electronic sphygmomanometer. However, the internal air path system of the traditional electronic sphygmomanometer cannot be completely closed, so that when the blood pressure is measured by auscultation, the pressure in the cuff will slowly decrease. Therefore, the medical staff needs to inflate the cuff to a state with high internal air pressure when inflating the cuff, which will cause the cuff to exert a large pressure on the patient, thereby affecting the measurement comfort of the patient, easily causing complaints of the patient and affecting the measurement experience of the patient. SUMMARY

[0004] The application provides a table type electronic sphygmomanometer to improve the measurement comfort of the patient and improve the measurement experience of the patient.

[0005] The technical scheme adopted by the application is as follows:

[0006] A table type electronic sphygmomanometer comprises:

[0007] A housing unit comprising a lower shell and an upper cover hinged to the lower shell;

[0008] A detection main control unit is arranged on the upper cover, and the detection main control unit comprises an air path assembly and a display and detection assembly, the display and detection assembly can detect the pressure in the air path assembly and display the pressure value in a columnar form, the air path assembly comprises an air path pipe and an exhaust structure communicated with the air path pipe, the exhaust structure has a closed state and an exhaust state, when the exhaust structure is in the exhaust state, the gas in the air path pipe can be exhausted through the exhaust structure;

[0009] An inflatable binding unit comprises a cuff capable of being communicated with the air path pipe and a pressurizing ball capable of inflating the cuff, the pressurizing ball has a manual valve capable of exhausting the cuff;

[0010] The table type electronic sphygmomanometer has a first measurement mode and a second measurement mode, in the first measurement mode, the cuff is exhausted through the exhaust structure, and in the second measurement mode, the cuff is exhausted through the manual valve.

[0011] According to the above technical scheme, in the first measurement mode, the cuff is exhausted through the exhaust structure, so that the oscillometric method can be used to measure the blood pressure of the patient, and in the second measurement mode, the cuff is exhausted through the manual valve, so that the auscultation method can be used to measure the blood pressure of the patient; since the table type electronic sphygmomanometer has the first measurement mode and the second measurement mode, the table type electronic sphygmomanometer can not only use the oscillometric method to measure the blood pressure of the patient, but also use the auscultation method to measure the blood pressure of the patient, thereby increasing the flexibility of the table type electronic sphygmomanometer, and the table type electronic sphygmomanometer can meet various measurement requirements of medical staff.

[0012] When the oscillometric method is used to measure the blood pressure of the patient, the medical staff needs to wrap the cuff around the arm of the patient, then switch the table type electronic sphygmomanometer to the first measurement mode, and then inflate the cuff by using the pressurizing ball, so that the gas enters the inside of the cuff and the cuff gradually expands, so that the cuff tightly holds the arm of the patient, at this time, the gas in the cuff enters the air path pipe, the exhaust structure is in the exhaust state, the gas in the air path pipe is gradually exhausted through the exhaust structure, the display and detection assembly calculates the blood pressure of the patient by analyzing the pressure fluctuation in the cuff, and finally the display and detection assembly displays the measurement result in a columnar form, so that the medical staff can view the measurement result, thereby realizing the measurement of the blood pressure of the patient by using the oscillometric method.

[0013] In the process of measuring the blood pressure of the patient by using the auscultation method, the medical staff needs to wrap the cuff on the arm of the patient, then place the stethoscope between the cuff and the arm of the patient, then switch the desktop electronic sphygmomanometer to the second measurement mode, switch the exhaust structure to the closed state, then inflate the cuff by using the pressure ball, so that the gas enters the inside of the cuff and makes the cuff gradually expand, so that the cuff tightly holds the arm of the patient, then the medical staff measures the blood pressure of the patient by capturing the Korotkoff sound through the stethoscope, and the display detection assembly displays the pressure value in the cuff in the form of a column; in the process of measuring the blood pressure of the patient by using the auscultation method, the medical staff exhausts the cuff by using the manual valve, thereby avoiding the situation that the cuff continuously leaks in the process of measuring the blood pressure of the patient by using the auscultation method, so as to avoid the situation that the pressure in the cuff continuously decreases under the action of non-human, so that the medical staff does not need to inflate the cuff to a state that the internal pressure of the cuff is relatively large when using the desktop electronic sphygmomanometer in the application to measure the blood pressure of the patient, so as to reduce the pressure applied to the patient by the cuff, thereby improving the measurement comfort of the patient, avoiding the situation that the patient easily complains, improving the measurement experience of the patient and improving the evaluation of the medical staff on the patient.

[0014] Since the shell unit in the application includes the lower shell and the upper cover hinged to the lower shell, the display detection assembly can display the blood pressure value in the form of a column, and the cuff is inflated by the pressure ball, thereby making the opening mode, the display mode of the pressure value and the inflation mode of the cuff of the desktop electronic sphygmomanometer in the application the same as those of the traditional mercury sphygmomanometer, thereby reducing the operation difficulty of the medical staff, reducing the learning difficulty of the medical staff, and thereby improving the use experience of the medical staff; at the same time, when the desktop sphygmomanometer is stored, the inflation restraint unit can also be stored in the lower shell, so as to achieve the effect of conveniently storing and arranging the desktop electronic sphygmomanometer.

[0015] In addition, since the desktop electronic sphygmomanometer in the application is provided with the pressure ball, thereby making the cuff in the application inflated by the pressure ball, compared with the scheme of the traditional electronic sphygmomanometer in the prior art, the design of the air pump is omitted, on the one hand, the production and manufacturing cost of the desktop electronic sphygmomanometer is reduced, on the other hand, the number of electronic components used by the desktop electronic sphygmomanometer is reduced, thereby reducing the failure rate of the desktop electronic sphygmomanometer, and also achieving the effects of conveniently repairing the electronic desktop sphygmomanometer and reducing the repair cost of the electronic sphygmomanometer, thereby improving the use experience of the user.

[0023] When the blood pressure is measured by using the auscultation method, the desktop electronic sphygmomanometer is switched to the second measurement mode, so that the exhaust structure is in the closed state, at this time, the valve core of the three-way valve is in the disconnected position, that is, the gas in the air path pipe cannot be exhausted through the three-way valve and the micro-pore valve, so as to ensure the air pressure in the cuff, thereby avoiding the situation that the cuff needs to be inflated to a high air pressure when the blood pressure is detected by using the auscultation method, and further improving the blood pressure measurement experience of the patient.

[0024] Optionally, the exhaust structure comprises a proportional valve, which is communicated with the air path pipe and can adjust the exhaust efficiency of the air path pipe.

[0026] When the blood pressure is measured by using the auscultation method, the desktop electronic sphygmomanometer is switched to the second measurement mode, so that the exhaust structure is in the closed state, at this time, the valve core inside the proportional valve is in the disconnected position, so that the gas in the air path pipe cannot be exhausted through the proportional valve, so as to ensure the air pressure in the cuff, thereby avoiding the situation that the cuff needs to be inflated to a high air pressure when the blood pressure is detected by using the auscultation method, and further improving the blood pressure measurement experience of the patient.

[0027] Optionally, the display and detection assembly comprises a main control board and a pressure sensor arranged on the main control board, the main control board is arranged on the side of the air path pipe, and the pressure sensor is arranged in communication with the air path pipe.

[0028] By adopting the technical scheme, since the pressure sensor is arranged in communication with the air path pipe, the pressure sensor can be used to detect the air pressure inside the air path pipe, so as to detect the air pressure inside the cuff. Compared with the mercury sphygmomanometer in the prior art, the mercury structure is avoided, so as to meet the requirements of various countries on medical devices, improve the accuracy of blood pressure measurement, and reduce the assembly difficulty of the table type electronic sphygmomanometer, improve the production efficiency of the table type electronic sphygmomanometer, and make the internal structure of the table type electronic sphygmomanometer more compact, so as to facilitate the miniaturization design of the table type electronic sphygmomanometer.

Since the installation surface is inclined, at least part of the area at the top of the protruding portion is avoided from the gas joint, so as to achieve the effect of facilitating the communication of the cuff with the gas joint, and the position where the gas path pipe is connected with the cuff is lowered, thereby increasing the stability of the upper cover in the open position.

[0041] Optionally, a battery electrically connected with the main control board is arranged in the installation cavity, the battery is located below the gas path assembly, and the battery is electrically connected with the main control board.

[0042] By adopting the above technical scheme, since the battery is electrically connected with the main control board, the battery of the desktop electronic sphygmomanometer itself is used to supply power to the power-consuming components of the desktop electronic sphygmomanometer, so that the desktop electronic sphygmomanometer does not rely on external power supply, thereby the use scenario of the desktop electronic sphygmomanometer is no longer limited by the power supply, and the flexibility of the desktop electronic sphygmomanometer is increased. Since the battery is located below the gas path assembly, the center of gravity of the upper cover in the open position is further lowered, thereby the stability of the upper cover in the open position is further increased, and to a certain extent, the force required by medical staff to open the upper cover is reduced, so as to achieve the effect of facilitating the opening of the upper cover by medical staff, thereby improving the use experience of medical staff.

[0043] Optionally, the shell is detachably connected with a battery compartment, the battery is arranged inside the battery compartment, and the battery is electrically connected with the main control board through the battery compartment.

[0044] By adopting the technical scheme, the battery is arranged inside the battery compartment, and the battery compartment is detachably connected to the shell, so that when the battery is insufficient, the battery compartment can be detached from the shell, and then the battery in the battery compartment is replaced, thereby achieving the effect of facilitating the replacement of the battery.

[0045] Optionally, the shell is provided with a through port communicated with the mounting cavity on the side away from the upper cover, and the battery compartment can be inserted into the mounting cavity through the through port.

[0046] By adopting the technical scheme, when the battery is replaced, a force away from the upper cover is applied to the battery compartment to make the battery compartment move away from the upper cover, and then the battery compartment moves to the outside of the shell and is separated from the shell through the through port, and then the battery is taken out of the battery compartment and a new battery is installed in the battery compartment, and then the battery compartment is installed in the shell through the through port, thereby reducing the disassembly difficulty of the battery compartment, and improving the replacement efficiency of the battery.

[0047] Optionally, the shell comprises a rear shell and a front shell, the rear shell is provided with a conductive sheet electrically connected to the main control board, and the battery compartment can abut against the conductive sheet to electrically connect the battery compartment to the main control board through the conductive sheet.

[0048] By adopting the technical scheme, after the battery compartment is installed in the shell, the battery compartment abuts against the conductive sheet, and then the battery compartment is electrically connected to the conductive sheet, and since the conductive sheet is electrically connected to the main control board, the electrical connection between the battery and the main control board is realized, thereby reducing the electrical connection difficulty between the battery and the main control board.

[0050] By adopting the technical scheme, after the battery compartment is installed to the shell, the clamping portion on the elastic arm extends into the matching portion on the battery compartment to limit the battery compartment by cooperation of the clamping portion and the matching portion, so as to increase the connection stability of the battery compartment and the shell, thereby ensuring the electrical connection stability of the battery and the main control board. When the battery compartment is separated from the shell, a pressing force is first applied to the elastic arm in a direction away from the battery compartment, so that the clamping portion is separated from the matching portion, and then a pulling force is applied to the battery compartment in a direction away from the upper cover, so that the battery compartment is finally separated from the shell, thereby achieving the effect of facilitating the separation of the battery compartment and the shell.

[0052] By adopting the technical scheme, when the upper cover is opened, an upward rotating force is first applied to one end of the upper cover away from the hinge shaft, so that the upper cover drives the limiting piece to move, and then the limiting column slides relative to the groove wall of the receiving groove by overcoming the protrusion arranged on the side wall of the receiving groove. When the upper cover is about to move to the open position, the limiting column contacts the protrusion arranged at the corresponding open position, and then a rotating force is continuously applied to the upper cover away from the lower shell, so that the limiting column overcomes the protrusion arranged at the corresponding open position and cooperates with the protrusion to stop together, thereby realizing the limitation of the upper cover in the open position by cooperation of the protrusion and the limiting portion.

[0053] Since the cooperation of the protrusion and the limiting column in the application can limit the upper cover in the open position or the closed position, the stability of the upper cover in the open position is increased, so as to avoid the situation that the upper cover moves toward the closed position due to the misoperation of medical staff or other personnel when the upper cover is in the open position, thereby improving the use experience of medical staff and the use safety of the desktop electronic sphygmomanometer. Meanwhile, the stability of the upper cover in the closed position is increased, so as to avoid the situation that the upper cover moves from the closed position to the open position due to the overturning of the desktop electronic sphygmomanometer when the desktop electronic sphygmomanometer is taken, thereby improving the use experience of the user, i.e. the medical staff.

[0054] Optionally, the upper cover is provided with a connecting piece, the connecting piece is located between the upper cover and the limiting piece, the hinge shaft penetrates the connecting piece and is fixedly connected to the limiting piece by a fastener.

[0055] By adopting the technical scheme, the hinge shaft is arranged in the connecting piece and fixedly connected to the limiting piece through the fastener, thereby increasing the stability of the hinge shaft to ensure the stability of the hinge connection between the upper cover and the lower shell, and facilitating the assembly of the hinge shaft; meanwhile, the connecting piece is arranged between the upper cover and the limiting piece, so that the connecting piece can be used to fixedly connect the limiting piece to the upper cover to increase the stability of the limiting piece, thereby further increasing the stability of the upper cover in the open position or the closed position.

[0056] Optionally, the direction in which the upper cover moves from the closed position to the open position is a first direction, and the width of the accommodating groove gradually decreases along the first direction.

[0057] By adopting the technical scheme, the width of the accommodating groove gradually decreases along the first direction, so that the friction between the limiting column and the accommodating groove becomes larger and larger when the upper cover is driven from the open position to the closed position, thereby making the required force for closing the upper cover larger and larger to avoid the sudden closing of the upper cover under the action of its own gravity and inertia, and further avoiding the situation that the upper cover squeezes the fingers of the medical staff when the upper cover is about to move to the closed position, thereby improving the use experience of the medical staff; meanwhile, the upper cover can produce a damping feeling when moving from the open position to the closed position, thereby improving the product quality of the desktop electronic sphygmomanometer and further improving the use experience of the medical staff.

Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0085] Referring to Figures 1 to 15 , a desktop electronic sphygmomanometer is disclosed, which comprises a housing unit 1, a detection main control unit 2 and an inflation restraint unit 3, wherein the housing unit 1 comprises a lower shell 11 and an upper cover 12 hinged to the lower shell 11; the detection main control unit 2 is arranged on the upper cover 12, and the detection main control unit 2 comprises a gas path assembly 21 and a display detection assembly 22, the display detection assembly 22 is capable of detecting the pressure in the gas path assembly 21 and displaying the pressure value in the form of a column, and the gas path assembly 21 comprises a gas path pipe 211 and an exhaust structure 212 communicated with the gas path pipe 211, the exhaust structure 212 has a closed state and an exhaust state, and when the exhaust structure 212 is in the exhaust state, the gas in the gas path pipe 211 can be exhausted through the exhaust structure 212; the inflation restraint unit 3 comprises a cuff 31 capable of being communicated with the gas path pipe 211 and a pressurizing ball 32 capable of inflating the cuff 31, and the pressurizing ball 32 has a manual valve 321 capable of exhausting the cuff 31; the desktop electronic sphygmomanometer has a first measurement mode and a second measurement mode, in the first measurement mode, the cuff 31 is exhausted through the exhaust structure 212, and in the second measurement mode, the cuff 31 is exhausted through the manual valve 321.

[0086] It can be understood that when the desktop electronic sphygmomanometer is in the first measurement mode, the exhaust structure 212 is in the exhaust state, so that the gas in the cuff 31 can be exhausted through the gas path pipe 211 and the exhaust structure 212; and when the desktop electronic sphygmomanometer is in the second measurement mode, the exhaust structure 212 is in the closed state, so that the gas in the cuff 31 cannot be exhausted through the gas path assembly.

[0087] Since the cuff 31 is exhausted through the exhaust structure 212 in the first measurement mode, the blood pressure of the patient can be measured by using the oscillometric method in the first measurement mode, and the cuff 31 is exhausted through the manual valve 321 in the second measurement mode, so that the blood pressure of the patient can be measured by using the auscultation method in the second measurement mode; and since the table type electronic sphygmomanometer in the application has the first measurement mode and the second measurement mode, the table type electronic sphygmomanometer in the application can not only measure the blood pressure of the patient by using the oscillometric method, but also measure the blood pressure of the patient by using the auscultation method, thereby increasing the flexibility of the table type electronic sphygmomanometer, and making the table type electronic sphygmomanometer in the application meet the various measurement needs of medical staff.

[0088] When the blood pressure of the patient is measured by using the oscillometric method, the medical staff needs to wrap the cuff 31 around the arm of the patient, then switch the table type electronic sphygmomanometer to the first measurement mode, and then inflate the cuff 31 by using the pressure ball 32, so that the gas enters the inside of the cuff 31 and makes the cuff 31 gradually expand, so that the cuff 31 tightly holds the arm of the patient, at this time, the gas in the cuff 31 enters the gas path pipe 211, the exhaust structure 212 is in the exhaust state, the gas in the gas path pipe 211 is gradually exhausted through the exhaust structure 212, the display detection assembly 22 calculates the blood pressure of the patient by analyzing the pressure fluctuation in the cuff 31, and finally the display detection assembly 22 displays the measurement result in the form of a column, so that the medical staff can view the measurement result, thereby realizing the measurement of the blood pressure of the patient by using the oscillometric method.

[0089] When the blood pressure of the patient is measured by using the auscultation method, the medical staff needs to wrap the cuff 31 around the arm of the patient, then place the stethoscope between the cuff 31 and the arm of the patient, then switch the desktop electronic sphygmomanometer to the second measurement mode, switch the exhaust structure 212 to the closed state, then inflate the cuff 31 by using the pressure ball 32, so that the gas enters the inside of the cuff 31 and the cuff 31 gradually expands, so that the cuff 31 tightly holds the arm of the patient, then the medical staff measures the blood pressure of the patient by capturing the Korotkoff sound through the stethoscope, and the display detection assembly 22 displays the pressure value in the cuff 31 in the form of a column; during the process of measuring the blood pressure of the patient by using the auscultation method, the medical staff deflates the cuff 31 by using the manual valve 321, thereby avoiding the situation that the cuff 31 continuously deflates when the blood pressure of the patient is measured by using the auscultation method, so as to avoid the situation that the pressure in the cuff 31 continuously decreases under the action of non-human, so that the medical staff does not need to inflate the cuff 31 to a state that the internal pressure of the cuff 31 is relatively large when the blood pressure of the patient is measured by using the desktop electronic sphygmomanometer in the application, so as to reduce the pressure applied to the patient by the cuff 31, thereby improving the measurement comfort of the patient, avoiding the situation that the patient easily complains, improving the measurement experience of the patient and improving the evaluation of the medical staff on the patient.

[0090] Since the shell unit 1 in the application includes the lower shell 11 and the upper cover 12 hinged to the lower shell 11, the display detection assembly 22 can display the blood pressure value in the form of a column, and the cuff 31 is inflated by the pressure ball 32, thereby making the opening mode, the display mode of the pressure value and the inflation mode of the cuff 31 of the desktop electronic sphygmomanometer in the application the same as those of the traditional mercury sphygmomanometer, thereby reducing the operation difficulty of the medical staff, reducing the difficulty of the medical staff to use, and thereby improving the use experience of the medical staff; at the same time, when the desktop sphygmomanometer is stored, the inflation restraint unit 3 can also be stored in the lower shell 11, so as to achieve the effect of conveniently storing and arranging the desktop electronic sphygmomanometer.

[0091] In addition, since the desktop electronic sphygmomanometer in the application is provided with the pressure ball 32, thereby making the cuff 31 in the application inflated by the pressure ball 32, compared with the scheme of the traditional electronic sphygmomanometer in the prior art, the design of the air pump is omitted, on the one hand, the production and manufacturing cost of the desktop electronic sphygmomanometer is reduced, on the other hand, the number of electronic components used by the desktop electronic sphygmomanometer is reduced, thereby reducing the failure rate of the desktop electronic sphygmomanometer, and also achieving the effects of conveniently repairing the electronic desktop sphygmomanometer and reducing the repair cost of the electronic sphygmomanometer, thereby improving the use experience of the user.

[0092] The exhaust structure 212 in the application is not limited in particular, and can adopt any one of the following embodiments:

[0093] In an embodiment, referring to Figure 5 and Figure 6 , the exhaust structure 212 comprises a micro-pore valve 217 and a first control valve 218, the micro-pore valve 217 is communicated with the gas path pipe 211, and the first control valve 218 is communicated with the gas outlet of the micro-pore valve 217.

[0094] It can be understood that the gas in the gas path pipe 211 can enter the micro-pore valve 217 through the gas inlet of the micro-pore valve 217. The valve core of the first control valve 218 has a communication position and a disconnection position. When the valve core of the first control valve 218 is in the communication position, the gas in the gas path pipe 211 can be discharged through the micro-pore valve 217 and the first control valve 218. When the valve core of the first control valve 218 is in the disconnection position, the first control valve 218 blocks the gas outlet of the micro-pore valve 217, so that the gas in the gas path pipe 211 cannot be discharged through the micro-pore valve 217.

[0095] When the blood pressure of the patient is measured by using the oscillometric method, the desktop electronic sphygmomanometer is switched to the first measurement mode, so that the exhaust structure 212 is in the exhaust state. At this time, the valve core in the first control valve 218 is in the communication position, and the gas outlet of the micro-pore valve 217 can be communicated with the outside, that is, the gas in the gas path pipe 211 can be discharged through the micro-pore valve 217 and the first control valve 218, so that the gas in the gas path pipe 211 can be slowly discharged through the micro-pore valve 217, to ensure that the work of measuring the blood pressure by using the oscillometric method is normally carried out.

[0096] When the blood pressure of the patient is measured by using the auscultation method, the desktop electronic sphygmomanometer is switched to the second measurement mode, so that the exhaust structure 212 is in the closed state. At this time, the valve core in the first control valve 218 is in the disconnection position, and the first control valve 218 closes the gas outlet of the micro-pore valve 217, so that the gas in the gas path pipe 211 cannot be discharged through the exhaust structure 212, thereby ensuring the gas pressure in the cuff 31, avoiding the situation that the medical staff needs to inflate the cuff 31 to a higher pressure, and improving the blood pressure measurement experience of the patient.

[0097] Further, referring to Figure 5 and Figure 6 , the exhaust structure 212 further comprises a second control valve 219, and the second control valve 219 is communicated with the gas path pipe 211.

[0098] It can be understood that the valve core of the second control valve 219 has a communication position and a disconnection position. When the valve core of the second control valve 219 is in the communication position, the gas in the gas path pipe 211 can be discharged through the second control valve 219. When the valve core of the second control valve 219 is in the disconnection position, the gas in the gas path pipe 211 cannot be discharged through the second control valve 219.

[0099] When the oscillometric method is used to measure blood pressure, the table type electronic sphygmomanometer is switched to the first measurement mode, so that the exhaust structure 212 is in the exhaust state, at this time, the valve core in the first control valve 218 is in the communication position, and the valve core in the second control valve 219 is in the disconnection position, then the cuff 31 is inflated, and then the gas in the cuff 31 is slowly discharged through the micro-pore valve 217 and the first control valve 218, and then the display detection assembly 22 calculates the sphygmomanometer according to the fluctuation of the pressure in the cuff 31. When the measurement is completed, the valve core in the second control valve 219 moves to the communication position, so that the gas in the cuff 31 is quickly discharged through the gas path pipe 211 and the second control valve 219, thereby improving the exhaust efficiency of the cuff 31.

[0100] The structure of the first control valve 218 and the second control valve 219 is not limited in the application. Preferably, the first control valve 218 and the second control valve 219 are both two-way electromagnetic valves, so as to realize automatic control of the exhaust structure 212 between the closed state and the exhaust state. In other embodiments, the first control valve 218 and the second control valve 219 can also be three-way electromagnetic valves or two-way manual valves 321, as long as they can realize switching of the exhaust structure 212 between the closed state and the exhaust state.

[0101] In the embodiment, the structure of the gas path pipe 211 is not limited, and preferably, referring to Figure 5 and Figure 6 , the gas path pipe 211 includes a main pipe 213, a first branch 214 connected to the main pipe 213, a second branch 215 connected to the main pipe 213, and a third branch 216 connected to the main pipe 213. The first branch 214 is used to connect the cuff 31 and the display detection assembly 22, the second branch 215 is used to connect the second control valve 219, and the third branch 216 is used to connect the micro-pore valve 217, so as to avoid the situation that the gas ports on the gas path pipe 211 are concentrated, causing difficulty in installation of the second control valve 219 and the micro-pore valve 217. In other embodiments, the first branch 214, the second branch 215 and the third branch 216 can be cancelled, and the second control valve 219 and the micro-pore valve 217 are directly connected to the main pipe 213.

[0102] In the second embodiment, the exhaust structure 212 includes a three-way valve and a micro-pore valve 217. The three-way valve has an inlet connected to the air path pipe 211. The micro-pore valve 217 is connected to one of the outlets of the three-way valve. The other outlet of the three-way valve is connected to the atmosphere.

[0103] It can be understood that the spool of the three-way valve has a first communication position, a second communication position and a disconnection position. When the spool of the three-way valve is in the first communication position, the gas in the air path pipe 211 can be discharged through the three-way valve and the micro-pore valve 217. When the spool of the three-way valve is in the second communication position, the gas in the air path pipe 211 can be directly discharged through the three-way valve. When the spool of the three-way valve is in the disconnection position, the gas in the air path pipe 211 cannot be discharged through the three-way valve and the micro-pore valve 217.

[0104] When the oscillometric method is used to measure blood pressure, the table electronic sphygmomanometer is switched to the first measurement mode, so that the exhaust structure 212 is in the exhaust state. At this time, the spool of the three-way valve is in the first communication position, and the micro-pore valve 217 is connected to the air path pipe 211 through the three-way valve. Therefore, when the oscillometric method is used to measure blood pressure, the cuff 31 can be slowly exhausted. After the measurement of blood pressure is completed, the spool of the three-way valve is switched to the second communication position, the connection between the micro-pore valve 217 and the air path pipe 211 is disconnected, and the air path pipe 211 is connected to the atmosphere through the three-way valve. Therefore, the gas in the cuff 31 can be quickly discharged through the air path pipe 211 and the three-way valve, so as to ensure that the oscillometric method can be used to measure blood pressure and improve the exhaust efficiency of the cuff 31.

[0105] When the oscillometric method is used to measure blood pressure, the table electronic sphygmomanometer is switched to the second measurement mode, so that the exhaust structure 212 is in the closed state. At this time, the spool of the three-way valve is in the disconnection position, that is, the gas in the air path pipe 211 cannot be discharged through the three-way valve and the micro-pore valve 217. Therefore, the air pressure in the cuff 31 is ensured, so as to avoid the situation that the cuff 31 needs to be inflated to a high air pressure when the auscultation method is used to detect blood pressure. Therefore, the experience of the patient in the measurement of blood pressure is improved.

[0106] The structure of the three-way valve is not limited in the present application. Preferably, the three-way valve is a three-way electromagnetic valve, so as to automatically switch the exhaust structure 212 between the closed state and the exhaust state. In other embodiments, the three-way valve can also be a manual three-way valve, as long as the gas in the air path pipe 211 can be discharged through the micro-pore valve 217 or the three-way valve.

[0107] In the present embodiment, the third branch 216 can be cancelled, and the three-way valve is connected to the second branch 215.

[0108] In the third embodiment, the exhaust structure 212 includes a proportional valve which is communicated with the air path pipe 211 and can adjust the exhaust efficiency of the air path pipe 211.

[0109] It can be understood that the proportional valve can linearly adjust the communication area between the air path pipe 211 and the atmosphere, the valve core of the proportional valve has a first communication position, a second communication position and a disconnected position, the air path pipe 211 can be exhausted through the proportional valve when the valve core is in the first communication position and the second communication position, and the exhaust efficiency when the valve core is in the first communication position is less than the exhaust efficiency when the valve core is in the second communication position, so that when the valve core is in the first communication position, the proportional valve constitutes the micro-pore valve 217 in the above-mentioned embodiment, and when the valve core is in the second communication position, the proportional valve constitutes the second control valve 219 in the above-mentioned embodiment.

[0110] When the sphygmomanometer is used to measure the blood pressure by using the oscillometric method, the sphygmomanometer is switched to the first measurement mode so that the exhaust structure 212 is in the exhaust state, at this time, the valve core in the proportional valve is in the first communication position, so that the gas in the cuff 31 can be slowly exhausted through the air path pipe 211 and the proportional valve, so as to ensure that the blood pressure can be measured by using the oscillometric method; and after the blood pressure measurement is completed, the valve core in the proportional valve is in the second communication position, so that the gas in the cuff 31 can be quickly exhausted, thereby improving the exhaust efficiency of the cuff 31.

[0111] When the sphygmomanometer is used to measure the blood pressure by using the auscultation method, the sphygmomanometer is switched to the second measurement mode so that the exhaust structure 212 is in the closed state, at this time, the valve core in the proportional valve is in the disconnected position, so that the gas in the air path pipe 211 cannot be exhausted through the proportional valve, so as to ensure the air pressure in the cuff 31, thereby avoiding the situation that the cuff 31 needs to be inflated to a high air pressure when the blood pressure is detected by using the auscultation method, and thereby improving the blood pressure measurement experience of the patient.

[0112] It should be noted that the positions of the valve core of the proportional valve in the first communication position and the second communication position are not specifically limited, which can be defined as the position of the valve core when the proportional valve is in a small opening degree of 2%, 5% or other small opening degrees as the first communication position, and the position of the valve core when the proportional valve is in a large opening degree of 80%, 90%, 100% or other large opening degrees as the second communication position.

[0113] In the third embodiment, the third branch 216 can also be cancelled, and the proportional valve is communicated with the second branch 215.

[0114] The structure of the display detection assembly 22 is not specifically limited, and preferably, the display detection assembly 22 is the display detection assembly 22 shown in the above-mentioned embodiment. Figure 3 ,Figure 4 and Figure 5 The display detection assembly 22 comprises a main control board 221 and a pressure sensor 222 arranged on the main control board 221. The main control board 221 is arranged on the side of the air path pipe 211, and the pressure sensor 222 is arranged in communication with the air path pipe 211.

[0115] It can be understood that the main control board 221 can analyze and process the air pressure detected by the pressure sensor 222, and the main control board 221 can control the exhaust structure 212 to switch between the closed state and the exhaust state, so as to realize the switching between the first measurement mode and the second measurement mode of the desktop electronic sphygmomanometer.

[0116] Since the pressure sensor 222 is arranged in communication with the air path pipe 211, the pressure sensor 222 can be used to detect the air pressure inside the air path pipe 211, so as to realize the detection of the air pressure inside the cuff 31. Compared with the mercury sphygmomanometer in the prior art, the mercury structure is avoided, which meets the requirements of various countries for medical devices and improves the accuracy of blood pressure measurement.

[0117] In addition, the main control board 221 is arranged on the side of the air path pipe 211, which reduces the communication difficulty between the air path pipe 211 and the pressure sensor 222, reduces the assembly difficulty of the desktop electronic sphygmomanometer, improves the production efficiency of the desktop electronic sphygmomanometer, and makes the internal structure of the desktop electronic sphygmomanometer more compact, so as to achieve the effect of facilitating the miniaturization design of the desktop electronic sphygmomanometer.

[0118] It should be noted that when the blood pressure is measured by auscultation method, if the pressure sensor 222 detects that the air pressure in the cuff 31 abnormally rises, the main control board 221 can also control the exhaust structure 212 to switch to the exhaust state, so that the gas in the cuff 31 is quickly exhausted, thereby ensuring the safety during the measurement of blood pressure.

[0119] Preferably, referring to Figure 5 The first branch 214 is communicated with the pressure sensor 222 through the communication pipe, so as to reduce the communication difficulty between the first branch 214 and the pressure sensor 222.

[0120] Further, referring to Figures 2 to 4 The detection main control unit 2 further comprises a housing 23 arranged on the upper cover 12, the housing 23 has a mounting cavity in the inside, the main control board 221 and the air path assembly 21 are arranged in the inside of the mounting cavity, the display detection assembly 22 further comprises a display screen 223, the display screen 223 is arranged on the side of the housing 23 away from the upper cover 12 and is electrically connected to the main control board 221, and the air path assembly 21 is located at the bottom of the display screen 223.

[0121] It can be understood that after the pressure sensor 222 transmits the air pressure information to the main control board 221, the main control board 221 processes the pressure information, and the display screen 223 displays the pressure information in the form of a column.

[0122] Since the main control board 221 and the air path assembly 21 are arranged inside the installation cavity, the main control board 221 and the air path assembly 21 can be protected by the shell 23 to ensure the service life of the main control board 221 and the air path assembly 21. Since the display screen 223 is arranged on the side of the shell 23 away from the upper cover 12, medical staff can easily check the pressure value of the patient, thereby improving the use experience of medical staff.

[0123] Since the display screen 223 is electrically connected to the main control board 221, the air pressure information processed by the main control board 221 can be displayed in the form of a column on the main control board 221. Since the air path assembly is located at the bottom of the display screen 223, on the one hand, the position of the display screen 223 is raised to facilitate medical staff to check the display content on the display screen 223, and on the other hand, the position of the air path assembly 21 is lowered to reduce the center of gravity when the upper cover 12 is in the open position, thereby increasing the stability of the upper cover 12 in the open position, and the connection position of the air path pipe 211 and the cuff 31 is located at the lower part of the upper cover 12, thereby further increasing the stability of the upper cover 12 in the open position.

[0124] Of course, in other embodiments, an LCD light column can also be used to replace the display screen 223 in the above embodiment.

[0125] The connection mode of the shell 23 and the upper cover 12 is not limited in the application, preferably, the shell 23 is provided with a fixing hole, the upper cover 12 is provided with a fixing column extending into the fixing hole, and the side of the shell 23 away from the upper cover 12 is provided with a screw threaded into the fixing hole, and the screw is screwed to the fixing column to fix the shell 23 to the upper cover 12 by the fixing column and the screw. In other embodiments, the shell 23 can also be fixedly connected to the upper cover 12 by clamping, gluing or other methods.

[0126] Preferably, referring to Figure 2 and Figure 3 , the side of the shell 23 away from the upper cover 12 is pasted with a decorative panel 233, the content displayed by the display screen 223 can be seen through the decorative panel 233, and the decorative panel 233 can shield the bolt to further improve the product quality of the desktop electronic sphygmomanometer.

[0127] The structure of the shell 23 is not limited in the application, preferably, referring to Figure 3 and Figure 4The housing 23 includes a rear housing 232 disposed on the upper cover 12 and a front housing 231 disposed on the rear housing 232. An installation cavity is formed between the front housing 231 and the rear housing 232. At least a portion of the bottom of the front housing 231 protrudes in a direction away from the rear housing 232 and forms a protrusion 234. The air passage assembly 21 is disposed corresponding to the protrusion 234.

[0128] Since a mounting cavity is formed between the front shell 231 and the rear shell 232, it is convenient to assemble the main control board 221 and the air circuit assembly 21 into the mounting cavity, thereby further improving the production efficiency of the desktop electronic blood pressure monitor. Furthermore, since at least a portion of the bottom of the front shell 231 protrudes in the direction away from the rear shell 232 and forms a protrusion 234, it increases the space of the mounting cavity on the one hand, so as to facilitate the installation and arrangement of multiple components. On the other hand, it ensures that the end face of the rear shell 232 facing the upper cover 12 is flat, so as to facilitate the installation of the housing 23 onto the upper cover 12. At the same time, it can also increase the connection stability between the housing 23 and the upper cover 12.

[0129] Furthermore, since the air circuit component is provided corresponding to the protrusion 234, the air circuit component is installed inside the protrusion 234, which facilitates the arrangement and installation of the air circuit component 21. At the same time, it increases the weight of the lower part of the housing 23, which further increases the stability of the top cover 12 when it is in the open position. Compared with the solution of increasing the volume of the entire front housing 231, it also reduces the volume of the housing 23, which facilitates the miniaturization design of the desktop electronic blood pressure monitor.

[0130] This application does not specify the connection method between the front shell 231 and the rear shell 232. Preferably, the front shell 231 and the rear shell 232 are fixedly connected by screws to increase the connection stability.

Figure 3 , Figure 4 , Figure 8 and Figure 9 The protrusion 234 has a square structure to ensure that there is sufficient space inside the mounting cavity for installing the air passage assembly 21. In other embodiments, the protrusion 234 can also be other shapes, such as semi-circular, as long as it can increase the space of the mounting cavity.

[0132] Furthermore, refer to Figure 5 , Figure 6 and Figure 8, the air path assembly 21 further comprises a mounting plate 224, the mounting plate 224 is provided with fixing rib positions 225 for fixing the air path pipe 211 and the exhaust structure 212, the front shell 231 is provided with a support plate 235 located in the mounting cavity, and the support plate 235 is located at the bottom of the mounting plate 224.

[0133] When assembling the air path assembly 21, the air path pipe 211 and the exhaust structure 212 are first mounted on the mounting plate 224 to fix the air path pipe 211 and the exhaust structure 212 by using the fixing rib positions 225, and then the mounting plate 224 is mounted above the support plate 235 to support the mounting plate 224 by using the support plate 235, thereby increasing the stability of the air path assembly 21, avoiding abnormal noise caused by the relative movement of the air path pipe 211 and the exhaust structure 212 with the cavity wall of the mounting cavity, improving the product quality of the desktop electronic sphygmomanometer, and achieving the effect of facilitating the assembly of the air path assembly 21, thereby improving the assembly efficiency of the air path assembly 21.

[0134] Preferably, the fixing rib positions 225 are arranged on the outer periphery of the main pipe 213 and the outer periphery of the first control valve 218 and the second control valve 219, and at least one fixing rib position 225 can be engaged with the main pipe 213, the first control valve 218 and the second control valve 219 to increase the stability of the main pipe 213, the first control valve 218 and the second control valve 219.

[0135] Further, referring to Figures 2 to 4 The top of the protruding portion 234 has a mounting surface 238, and the mounting surface 238 is provided with a key module 25, and the key module 25 is electrically connected to the main control board 221.

[0137] Since the key module 25 is arranged on the mounting surface 238, the mounting surface 238 is located at the top of the protruding portion 234, thereby achieving the effect of facilitating the operation of the key module 25 by medical personnel, and reasonably utilizing the top space of the protruding portion 234 to further achieve the effect of facilitating the miniaturization design of the desktop electronic sphygmomanometer; and since the key module 25 is electrically connected to the main control board 221, the start and stop of the desktop electronic sphygmomanometer and the switching of the measurement mode can be controlled by using the key module 25, thereby achieving the effect of facilitating the control of the start and stop of the desktop electronic sphygmomanometer and the switching of the measurement mode by medical personnel.

[0138] Further, referring to Figure 2And Figure 4 The mounting surface 238 is arranged to be inclined downward in a direction away from the rear shell 232.

[0139] It should be noted that the mounting surface 238 is arranged to be inclined downward in a direction away from the rear shell 232, which refers to the relative upper cover 12 in the open position.

[0140] Due to the mounting surface 238 being arranged to be inclined downward in a direction away from the rear shell 232, the key module 25 is arranged to be inclined downward in a direction away from the rear shell 232, so that medical personnel can more directly view the key module 25, thereby achieving the effect of facilitating medical personnel to operate the key module 25.

[0141] Further, referring to Figure 2 And Figure 9 The front shell 231 is provided with a gas connector 236 in communication with the gas path pipe 211, the gas connector 236 is located on the side of the front shell 231 away from the rear shell 232, and the gas connector 236 is located above the protruding portion 234, and the cuff 31 is connected to the gas path pipe 211 through the gas connector 236.

[0142] It can be understood that the cuff 31 is connected to the gas connector 236 through the cuff pipe possessed by itself.

[0143] Since the gas connector 236 is located on the side of the front shell 231 away from the rear side, and the gas connector 236 is located above the protruding portion 234, on the one hand, it can reasonably utilize the space above the protruding portion 234 to further reduce the volume of the desktop electronic sphygmomanometer, on the other hand, it can also facilitate the communication between the gas path pipe 211 and the gas connector 236, and on the other hand, it can also achieve the effect of facilitating the communication between the gas path pipe 211 and the cuff 31, and since the mounting surface 238 is inclined, at least part of the area at the top of the protruding portion 234 is formed to avoid the gas connector 236, so as to achieve the effect of facilitating the communication between the cuff 31 and the gas connector 236, and reduce the position where the gas path pipe 211 and the cuff 31 are connected, thereby increasing the stability when the upper cover 12 is in the open position.

[0146] The power supply mode of the desktop electronic sphygmomanometer is not specifically limited in the present application, preferably, referring to Figure 3 AndFigure 4 The battery 24 is arranged in the installation cavity and is electrically connected with the main control board 221. The battery 24 is located below the air path assembly 21 and is electrically connected with the main control board 221.

[0147] It can be understood that the desktop electronic sphygmomanometer is powered by the battery 24.

[0148] Since the battery 24 is electrically connected with the main control board 221, the battery 24 of the desktop electronic sphygmomanometer itself is used to power the power components of the desktop electronic sphygmomanometer, so that the desktop electronic sphygmomanometer no longer relies on external power supply, thereby the use scene of the desktop electronic sphygmomanometer is no longer limited by the power supply, so as to increase the flexibility of the desktop electronic sphygmomanometer. Since the battery 24 is located below the air path assembly 21, the center of gravity when the upper cover 12 is in the open position is further reduced, thereby the stability when the upper cover 12 is in the open position is further increased, and the force required by the medical staff to open the upper cover 12 is reduced to a certain extent, so as to facilitate the medical staff to open the upper cover 12, thereby improving the use experience of the medical staff.

[0149] The application does not make specific limitation on the connection mode of the battery 24 and the shell 23. Preferably, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 10 The shell 23 is detachably connected with the battery compartment 241. The battery 24 is arranged in the interior of the battery compartment 241. The battery 24 is electrically connected with the main control board 221 through the battery compartment 241.

[0150] It can be understood that the battery 24 is detachably connected with the shell 23 through the battery compartment 241.

[0151] Since the battery 24 is arranged in the interior of the battery compartment 241 and the battery compartment 241 is detachably connected with the shell 23, when the battery 24 is insufficient, the battery compartment 241 can be taken off from the shell 23, and then the battery 24 in the battery compartment 241 can be replaced, thereby achieving the effect of facilitating the replacement of the battery 24. Since the battery 24 is electrically connected with the main control board 221 through the battery compartment 241, after the battery compartment 241 is installed on the shell 23, the battery 24 can be electrically connected with the main control board 221, so as to reduce the connection difficulty of the battery 24 and the main control board 221, thereby simplifying the structure design of the desktop electronic sphygmomanometer and reducing the production cost of the desktop electronic sphygmomanometer.

[0152] And, in the application, the battery 24 is arranged in the battery compartment 241, and the battery compartment 241 is arranged in a detachable manner with the shell 23, which reduces the difficulty of replacing the battery 24 compared with the case that the battery 24 is arranged in a detachable manner with the shell 23, thereby further improving the use experience of medical staff.

[0153] Preferably, the battery 24 is a dry battery, which can be replaced at any time and reduces the production cost of the desktop electronic sphygmomanometer compared with the case that the battery 24 is a lithium battery.

[0155] When replacing the battery 24, first apply a force to the battery compartment 241 away from the upper cover 12 to make the battery compartment 241 move away from the upper cover 12, and then make the battery compartment 241 move to the outside of the shell 23 through the through port and separate from the shell 23, then take out the battery 24 from the battery compartment 241, install a new battery 24 in the battery compartment 241, and then install the battery compartment 241 in the shell 23 through the through port, thereby reducing the disassembly difficulty of the battery compartment 241, and further improving the replacement efficiency of the battery 24.

[0156] In other embodiments, the through port can also be arranged on the side of the shell 23 to take and place the battery compartment 241 on the side of the shell 23.

[0157] The application does not make specific limitation on the electrical connection manner of the battery compartment 241 and the main control board 221, and preferably, referring to Figure 4 , the shell 23 includes a rear shell 232 and a front shell 231, the rear shell 232 is provided with a conductive sheet 237 electrically connected with the main control board 221, and the battery compartment 241 can abut against the conductive sheet 237 to make the battery compartment 241 electrically connected with the main control board 221 through the conductive sheet 237.

[0158] It can be understood that the conductive sheet 237 is electrically connected with the main control board 221 through the wire, so that when the battery compartment 241 is electrically connected with the conductive sheet 237, the battery 24 in the battery compartment 241 can supply power to the main control board 221; the inside of the battery compartment 241 is provided with a spring capable of contacting the electrode of the battery 24, and the outside of the battery compartment 241 is provided with a battery spring electrically connected with the spring. After the battery compartment 241 is installed in the shell 23, the battery spring contacts the conductive sheet 237 to realize the electrical connection between the battery 24 and the main control board 221, and the battery spring can also increase the contact stability between the battery compartment 241 and the conductive sheet 237 to ensure the electrical connection stability between the battery 24 and the main control board 221.

[0159] After the battery compartment 241 is installed in the shell 23, the battery compartment 241 contacts the conductive sheet 237, and then the battery compartment 241 is electrically connected with the conductive sheet 237. Since the conductive sheet 237 is electrically connected with the main control board 221, the electrical connection between the battery 24 and the main control board 221 is realized, thereby reducing the electrical connection difficulty between the battery 24 and the main control board 221.

[0160] In other embodiments, the battery compartment 241 can also be electrically connected with the main control board 221 through a wire, or the electrical connection between the battery compartment 241 and the main control board 221 can be realized by using a pin.

[0161] Further, referring to Figure 9 The front shell 231 is provided with an elastic arm 239, which is located on the side or top of the battery compartment 241. The side of the elastic arm 239 facing the battery compartment 241 is provided with a clamping part, and the side of the battery compartment 241 facing the elastic arm 239 is provided with a matching part capable of clamping cooperation with the clamping part.

[0162] After the battery compartment 241 is installed in the shell 23, the clamping part on the elastic arm 239 extends into the matching part on the battery compartment 241 to limit the battery compartment 241 by cooperation of the clamping part and the matching part, thereby increasing the connection stability between the battery compartment 241 and the shell 23, and ensuring the electrical connection stability between the battery 24 and the main control board 221. When the battery compartment 241 is separated from the shell 23, a pressing force is first applied to the elastic arm 239 in a direction away from the battery compartment 241, so that the clamping part is separated from the matching part, and then a pulling force is applied to the battery compartment 241 in a direction away from the upper cover 12, so that the battery compartment 241 is finally separated from the shell 23, thereby achieving the effect of facilitating the separation of the battery compartment 241 from the shell 23.

[0163] More preferably, referring to Figure 9The elastic arm 239 is located at the bottom of the battery compartment 241, so that when the battery compartment 241 is disassembled, only downward pressure is applied to the elastic arm 239 to facilitate disassembly of the battery compartment 241, and the appearance quality of the desktop electronic sphygmomanometer is improved. Of course, in other embodiments, the elastic arm 239 can also be provided on the side of the battery compartment 241.

[0164] Preferably, the bottom of the shell 23 is provided with at least two partitioning ribs at the through port, and the shell 23 between the partitioning ribs constitutes the elastic arm 239, so as to reduce the production difficulty and cost of the shell 23.

[0165] Preferably, the clamping part is a protrusion provided on the side of the elastic arm 239 facing the battery compartment 241, and the cooperating part is a groove-shaped structure provided on the side of the battery compartment 241 facing the elastic arm 239, so as to limit the battery compartment 241 by clamping the protrusion and the groove-shaped structure, thereby increasing the stability of the battery compartment 241. Of course, in other embodiments, the clamping part can also be a groove-shaped structure, the cooperating part can also be a block-shaped structure, or both can be block-shaped structures.

[0166] In other embodiments, the battery 24 can also be fixedly connected to the mounting cavity, and the battery 24 can be a lithium battery that can be charged.

[0167] In other embodiments, the battery 24 can also be omitted, so that the desktop electronic sphygmomanometer is powered by an external power source; or, on the basis of the battery 24, a power interface is added to realize power supply by one of the battery 24 and the external power source.

[0168] In other embodiments, the display detection assembly 22 can also only include the main control board 221, the pressure sensor 222, and the display screen 223, and the main control board 221 and the display screen 223 are fixedly connected to the upper cover 12, so as to reduce the production cost of the desktop electronic sphygmomanometer.

[0169] In a preferred embodiment, referring to Figure 3 , Figure 11 , Figure 12 and Figure 13 , the upper cover 12 has a closed position covering the lower shell 11 and an open position opening the lower shell 11, the upper cover 12 is provided with a hinge shaft 121 and a limiting piece 122, the hinge shaft 121 penetrates the lower shell 11, the limiting piece 122 is provided with a receiving groove 123, the lower shell 11 is provided with a limiting column 111 located in the receiving groove 123, a side wall of the receiving groove 123 is provided with a protrusion 127 capable of blocking the limiting column 111, and cooperation of the protrusion 127 and the limiting column 111 can limit the upper cover 12 in the open position or the closed position.

[0170] It can be understood that the upper cover 12 is hinged to the lower shell 11 through the hinge shaft 121; when the upper cover 12 is in the closed position, the upper cover 12 and the lower shell 11 together form a containing cavity, and the cuff 31 and the pressurizing ball 32 can be accommodated in the containing cavity; the protrusions 127 are provided with two protrusions corresponding to the positions of the limiting posts 111 when the upper cover 12 is in the open position and when the upper cover 12 is in the closed position, so that when the upper cover 12 is in the open position, the protrusions 127 corresponding to the open position cooperate with the limiting posts 111 to limit the upper cover 12 in the open position, and when the upper cover 12 is in the closed position, the protrusions 127 corresponding to the closed position cooperate with the limiting posts 111 to limit the upper cover 12 in the closed position.

[0171] When the upper cover 12 is opened, an upward rotating force is first applied to one end of the upper cover 12 away from the hinge shaft 121, so that the upper cover 12 drives the limiting member 122 to move, and then the limiting post 111 slides relative to the groove wall of the containing groove 123 by overcoming the protrusion 127 provided on the side wall of the containing groove 123, and when the upper cover 12 is about to move to the open position, the limiting post 111 contacts the protrusion 127 corresponding to the open position, and then a rotating force is continuously applied to the upper cover 12 in a direction away from the lower shell 11, so that the limiting post 111 overcomes the protrusion 127 corresponding to the open position and cooperates with the protrusion 127 to stop together, thereby realizing the limitation of the upper cover 12 in the open position by the stop cooperation of the protrusion 127 and the limiting portion.

[0172] Since the cooperation of the protrusion 127 and the limiting post 111 in the present application can limit the upper cover 12 in the open position or the closed position, the stability of the upper cover 12 in the open position is increased, so as to avoid the situation that the upper cover 12 moves towards the closed position due to the misoperation of medical staff or other personnel when the upper cover 12 is in the open position, thereby improving the use experience of medical staff and the use safety of the desktop electronic sphygmomanometer, and increasing the stability of the upper cover 12 in the closed position, avoiding the situation that the upper cover 12 moves from the closed position to the open position due to the inversion of the desktop electronic sphygmomanometer when the desktop electronic sphygmomanometer is taken, thereby improving the use experience of the user, medical staff.

[0173] Preferably, the cross-sectional shape of the protrusion 127 is semicircular, so as to ensure that when the medical staff applies a larger force to the upper cover 12, the limiting post 111 can overcome the protrusion 127, and the limiting member 122 is made of plastic material, so that when the limiting post 111 extrudes the protrusion 127, the protrusion 127 can deform slightly, so as to further ensure that the limiting post 111 can overcome the protrusion 127.

[0174] Further, with reference to Figure 3 , Figure 11 andFigure 12 The upper cover 12 is provided with a connecting piece 124 located between the upper cover 12 and the limiting piece 122, the hinge shaft 121 is threaded through the connecting piece 124 and fixedly connected to the limiting piece 122 by a fastener, and the rigidity of the connecting piece 124 is greater than that of the limiting piece 122.

[0175] Since the hinge shaft 121 is threaded through the connecting piece 124 and fixedly connected to the limiting piece 122 by a fastener, on the one hand, the stability of the hinge shaft 121 is increased to ensure the stability of the hinge connection between the upper cover 12 and the lower shell 11, and on the other hand, the effect of facilitating the assembly of the hinge shaft 121 is achieved; at the same time, since the connecting piece 124 is located between the upper cover 12 and the limiting piece 122, the limiting piece 122 can be fixedly connected to the upper cover 12 by the connecting piece 124 to increase the stability of the limiting piece 122, thereby further increasing the stability of the upper cover 12 in the open position or the closed position.

[0176] The structure of the fastener is not specifically limited in the application, preferably, the fastener is a screw, that is, the hinge shaft 121 is fixedly connected to the limiting piece 122 by a screw. In other embodiments, the fastener can also be other structures capable of fixedly connecting the hinge shaft 121 to the limiting piece 122.

[0177] Preferably, the connecting piece 124 is a plate-shaped structure, and the connecting piece 124 is made of aluminum alloy or other metal materials, the limiting piece 122 is fixedly connected to the connecting piece 124, and the connecting piece 124 is fixedly connected to the upper cover 12 to ensure the stability of the limiting piece 122.

[0178] Further, referring to Figure 14 The direction in which the upper cover 12 moves from the closed position to the open position is the first direction, and the width of the accommodating groove 123 gradually decreases along the first direction, so that the friction between the limiting column 111 and the accommodating groove 123 becomes larger and larger when the upper cover 12 is driven from the open position to the closed position, thereby making the required force larger and larger during the closing process of the upper cover 12, to avoid the sudden closing of the upper cover 12 under the action of its own gravity and inertia, thereby avoiding the situation that the upper cover 12 squeezes the fingers of the medical staff when it is about to move to the closed position, to improve the use experience of the medical staff; at the same time, the upper cover 12 can produce a damping feeling when moving from the open position to the closed position, thereby improving the product quality of the desktop electronic sphygmomanometer and further improving the use experience of the medical staff.

[0179] Further, referring to Figure 15The limiting member 122 has a first wall body 125 and a second wall body 126 which is spaced from the first wall body 125, and the first wall body 125 and the second wall body 126 form a containing groove 123, the convex 127 is arranged on the side of the first wall body 125 facing the second wall body 126, one end of the bottom of the second wall body 126 is fixedly connected with the limiting member 122, and the other end of the top of the second wall body 126 can move relative to the first wall body 125, so that when the upper cover 12 is driven towards the closing position, the limiting column 111 can move relative to the second wall body 126, and the limiting column 111 needs to exert a extrusion force on the second wall body 126 in a direction away from the first wall body 125, so that the second wall body 126 moves relative to the first wall body 125, thereby making the damping force of the limiting member 122 when the upper cover 12 is closed in a preferable range, to avoid the situation that the damping force is too large to cause the closing to be difficult, and at the same time avoid the situation that the second wall body 126 is easily damaged due to the large extrusion force of the second wall body 126 on the limiting column 111, thereby ensuring the product quality of the desktop electronic blood pressure meter.

[0180] The application does not make specific limitations on the manufacturing material of the limiting column 111, preferably, the limiting column 111 is made of rubber or silicone material, so that the limiting column 111 has elasticity, thereby on the one hand, the damping effect on the upper cover 12 can be improved, to improve the hand feeling of the medical staff when opening or closing the upper cover 12, on the other hand, the situation that one of the limiting column 111 or the limiting member 122 is damaged can be avoided, thereby further ensuring the service life of the desktop electronic blood pressure meter, and on the other hand, the noise generated when the upper cover 12 moves can be reduced, to further improve the product quality of the desktop electronic blood pressure meter.

[0181] In other embodiments, the limiting column can also be made of plastic, aluminum alloy or other materials.

[0182] The places not described in the application can be realized by adopting or referring to the existing technology.
