Apparatus and methods are described including an implantable device having first and second longitudinal ends, the device having a length of less than 80 mm when the device is unconstrained. The device includes struts arranged such that, when the device is unconstrained, along a continuous portion of the device having a length that is at least 5 mm, a maximum inter-strut distance defined by any set of two adjacent struts is more than 1.5 times as great as a maximum inter-strut distance defined by any set of two adjacent struts within longitudinal portions of the device within 3 mm of the longitudinal ends of the device. Other applications are also described.

To provide a non-invasive blood pressure estimation apparatus, which can accurately estimate systolic blood pressure from blood flow sound of a dialysis patient and continuously estimate systolic blood pressure by continuously picking up the blood flow sound. A blood pressure estimation apparatus creates a standard pulse curve by relating a start point and end point of a rising phase of a pulse wave to diastolic blood pressure and systolic blood pressure, respectively, creates a correspondence curve between blood flow sound power and estimated blood pressure by contrasting the standard pulse curve with the blood flow sound power curve obtained from blood flow sound at a shut site, with the two curves plotted on the same time axis, derives a systolic blood pressure estimation linear function from the correspondence curve, inputs a measured maximum value of the blood flow sound power into the linear function, and thereby estimates systolic blood pressure.

The invention belongs to the technical field of non-invasive blood pressure detection and particularly relates to a non-invasive blood pressure continuous detection device and a non-invasive blood pressure continuous detection method. The non-invasive blood pressure continuous detection device comprises a volume pulse wave image detection module, an electrocardiogram detection module and a signal analysis processing module; the volume pulse wave image detection module is used for acquiring a direct current component and an alternate current component in a blood volume pulse wave; the electrocardiogram detection module is used for acquiring an electrocardiosignal of a human body; and the signal analysis processing module is used for acquiring PWV (Pulse Wave Velocity) information according to the electrocardiosignal acquired by the electrocardiogram detection module and the alternate current component detected by the volume pulse wave image detection module, acquiring blood vessel radius information according to the alternate current component and the direct current component and acquiring continuous blood pressure information according to the PWV information and the blood vessel radius information. Due to implementation of the non-invasive blood pressure continuous detection device and the non-invasive blood pressure continuous detection method which are disclosed by the invention, influence of variation of the blood vessel radius on the blood pressure in the long-term non-invasive blood pressure measurement process is removed, accuracy of long-term detection is improved, and times of continuously calibrating the blood pressure are reduced.

The invention discloses a set of devices used for measuring blood pressure of a primate in the waking state. The set of devices comprises a general monkey chair (1) provided with a cross-shaped separation and fixing plate (2) for limbs and a blood pressure instrument rack (3). The cross-shaped separation and fixing plate (2) is mounted to an upper horizontal support rack of the general monkey chair (1) through screws. The blood pressure instrument rack (3) is installed on the side surface of a lower horizontal support rack of the general monkey chair (1). The set of devices used for measuring blood pressure of the primate in the waking state has following beneficial effects: the set of devices has a simple structure and is reasonably designed; by proper limitation of an animal, the animal can be adapted and subjected to blood pressure measurement in a short time in the waking state; and therefore more accurate data of blood pressure is obtained and time spent on training is largely shortened.

The invention relates to a medical appliance for detecting blood pressure, in particular to an ambulatory blood pressure monitor. Due to a blood pressure aberration rate analysis module arranged on a traditional blood pressure monitor, the ambulatory blood pressure monitor can perform statistical analysis on blood pressure value to obtain the fluctuation of the blood pressure so as to provide the blood pressure aberration parameter within a time space (24h), so that the blood pressure monitor is beneficial for doctors to adopt the most optimized treatment solution and evaluate the risk of hypertension complications.
