Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. 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.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

One embodiment of the non-invasive arterial blood pressure monitor shown in fig. 1 and 2 comprises afixing ring 1 adapted to a monitored site, a sensor assembly mounted on thefixing ring 1, and anair supply device 2 communicated with the sensor assembly.

Thefixing ring 1 is an elastic ring to adapt to different requirements of patients, and when the fixing ring is used, thefixing ring 1 is sleeved on the part to be monitored of the wrist of the patient.

The sensor assembly comprises amounting structure 3 connected with thefixing ring 1 and a sucker structure arranged on themounting structure 3 and a pressure sensor arranged inside the sucker structure. Themounting structure 3 is a flexible plate which can be detachably connected with thefixing ring 1. Be equipped with basically and cover completely onmounting structure 3 is towards theslide rail 4 of the one side of monitored site,slide rail 4 is followedmounting structure 3 is towards the one side distribution of buckling of monitored site. Theslide rail 4 does not penetrate through theinstallation structure 3, namely is arranged on one side of theinstallation structure 3 close to the part to be monitored. Pressure sensor includesarc base 5 and locatespressure sensing unit 6 on thearc base 5, the setting ofarc base 5 further improves and the firmness of being laminated by the monitoring position. When the pressuresensitive unit 6 is in contact with the radial artery of the wrist, pressure change generated inside the artery can penetrate through the artery wall, subcutaneous tissues and skin to form pulse beat, and the pressuresensitive unit 6 converts mechanical wave signals of the pulse into electric signals and transmits the electric signals to the subsequent conditioning circuit module through the internal gold wire and the signal acquisition circuit module. The sucking disc structure include with theslider 7 of 4 adaptations of slide rail and with thedisk body 8 thatslider 7 is connected,slider 7 slides alongslide rail 4, drivesdisk body 8 and pressure sensor synchronous motion to monitor patient's monitored position comprehensively, thereby confirm the strongest point that the pulse is beated, then begin continuous monitoring. Be equipped with in theslider 7 with thecavity 9 ofdisk body 8 intercommunication, pressure sensorfixes disk body 8 is kept away from one side ofslider 7,disk body 8 is for leaking hopper-shaped, and pressure sensor is close to the monitored site setting of patient to more closely laminate rather than.

Thegas supply device 2 is communicated with thecavity 9 of the slidingblock 7 through a connectingpipeline 10, and the connectingpipeline 10 is arranged on the side wall of thecavity 9. The chuck structure has a first state in which a pressing force toward the monitored site is applied to the pressure sensor inside under the gas pressure supplied from thegas supply device 2, and a second state in which the pressing force against the pressure sensor is released when the gas pressure disappears. Because the pulse of the patient's position of treating monitoring intensity differs, consequently need the sensor module to treat the pulse of each department of monitoring position and monitor the comparison to obtain the strongest point of pulse beat, then carry out continuous monitoring again. When carrying out the monitoring of a certain specific position like this, just need to laminate closely pressure sensor and this specific position to guarantee the accuracy of monitoring, and when removing pressure sensor's position, then need remove pressure sensor and this specific position's closely laminating, realize pressure sensor and specific position's laminating through aerifing and deflating to thedisk body 8 of sucker structure, the mode is simple, easily realizes.

Because a certain distance needs to be reserved between two adjacent slidingrails 4, in order to ensure that the pressure sensor can completely cover the monitored part when moving, thetray body 8 is a disc, the slidingrails 4 are long-strip-shaped, and the diameter of the disc is 1.1-1.2 times of the width of the slidingrails 4.

Theslider 7 is also connected with a driving structure, and the driving structure can be a micro motor and is integrated in theslider 7.

When the blood pressure of a patient needs to be monitored, the elastic ring is sleeved on the wrist of the patient, then theair supply device 2 sucks air in thedisk body 8 through the connectingpipeline 10, so that the pressure sensor is tightly attached to a certain specific position of a part to be monitored, the blood pressure value of the position is obtained, and the blood pressure value is recorded and stored. Theair supply device 2 inflates air into thedisc body 8 through the connectingpipeline 10, the pressure sensor is separated from the joint with a specific position, the sensor assembly is moved to the next position along theslide rail 4 of themounting structure 3, the air suction and inflation steps are repeated, and therefore the strongest point of pulse jumping is determined, and continuous monitoring is conducted on the strongest point.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
