A system and method for taking non-invasive blood pressure and other vascular parameter measurements includes placing a vascular compression device about an appendage of a subject. An arterial / venous occlusion cuff is placed about a base of the appendage. The vascular compression device is activated to generate compression ischemia in the appendage. The arterial / venous occlusion cuff is pressurized to generate arterial / venous occlusion in the appendage. The vascular compression device is deactivated. The arterial / venous occlusion cuff is gradually depressurized to allow blood and other body fluids to flow into the appendage and thereupon determine vascular parameters such as, for example, systolic arterial blood pressure, diastolic arterial blood pressure, venous blood pressure, arterial blood flow, blood vessel compliance, and appendage blood volume.

An adjustable radial and ulnar vascular compression wristband assists in achieving partial or full occlusion of a blood vessel when applied to a patient's wrist during or following a medical procedure. At least two adjustably inflatable non-adjacent balloons on the wristband apply preferential compression to portions of the circumference of the wrist, including in particular those portions overlying the ulnar and radial arteries.

An adjustable radial and ulnar vascular compression wristband and its method of use assists in achieving partial or full occlusion of a blood vessel to achieve patent hemostasis when applied to a patient's wrist during or following a medical procedure. At least two adjustably inflatable non-adjacent balloons on the wristband apply preferential compression to portions of the circumference of the wrist, including in particular those portions overlying the ulnar and radial arteries.

A vascular compression apparatus and method for applying pressure onto an area of a patient generally including a blood vessel and a wound site, such as a blood vessel puncture after a cannulated procedure, for the purpose of controlling bleeding and achieving hemostasis.

A vascular compression apparatus and method for applying pressure onto an area of a patient generally including a blood vessel and a wound site, such as a blood vessel puncture, after a cannulated procedure for the purpose of controlling bleeding and achieving hemostasis. The vascular compression apparatus includes a handle, a shaft and a pad. The shaft extends generally downward from the center of the bottom side of the handle. The pad is connected generally off-center of its top side to the bottom end of the shaft. The bottom side of the pad is convex to allow the vascular compression device to be rocked back and forth. In use, the pad is generally placed proximal to the catheter insertion site and over the blood vessel containing the catheter. The device is rocked proximally to control blood flow while removing the catheter. After the catheter is removed from the puncture site, the device is rocked distally to the puncture site, where pressure is applied until hemostasis is achieved.

The purpose of the present invention is to provide information pertaining to a collapsed state of a blood vessel intended to be punctured, such collapse caused by the pressing of an ultrasonic probe when acquiring ultrasonic images of the blood vessel. A puncture assistance system 10 is provided with: a vascular diameter detecting means 18 for detecting a vascular diameter during acquisition of ultrasonic images from an ultrasonic diagnostic device 11; a puncture assistance information generating means 12 that generates puncture assistance information for determining whether puncturing is possible on the basis of the collapsed state of a blood vessel B due to pressing of an ultrasonic probe 15 against the skin S, such generation performed by comparing a current vascular diameter detected by the vascular diameter detecting means 18 and a pre-stored reference vascular diameter; and a monitor 19 for presenting the puncture assistance information. As the puncture assistance information, the following are found: a vascular compression rate representative of the ratio of the vascular diameter during ultrasonic image acquisition relative to the pre-stored reference vascular diameter; and a puncture feasibility rate representative of the current ease of puncturing at the blood vessel B due to the pressing of the ultrasonic probe 15.

A ratcheting adjustable vascular compression device assists in achieving partial or full occlusion of a blood vessel when applied to a patient's limb, during or following a medical procedure. During deployment, a compression pad on the device applies preferential compression to at least one portion of the circumference of the limb. Further, securement, adjustment and rapid release of the device are all enabled by an alternate ratcheting mechanism that enables gradual adjustments to be made to the tightness and thus to the compression applied without releasing the device, so as to permit patent blood flow through blood vessels in the limb during the compression period.

Provided is a bag-shaped structure capable of suppressing expansion of the side wall portion and improving blood vessel compressive properties. The bag-like structure (32) is used for the cuff (12) for the blood pressure monitor (1). (100) to compress, the bag-like structure has: an inner wall (41), which is arranged on the side of the living body (100); an outer wall (42), which is opposite to the inner wall (41); a pair of side walls ( 43), which are provided continuously with respect to the inner wall portion (41) and the outer wall portion (42), having a bent portion (43a) bent toward the inner space; and a reinforcing member (44), which is provided on a pair of side wall portions (43) has a hardness higher than that of the side wall portion (43), and has shape followability in a winding direction toward the living body (100).

The invention relates to medical apparatus and instruments, in particular to a vascular compression haemostatic device which is capable of stopping bleeding more exactly and more efficiently. The vascular compression haemostatic device comprises a shell and a motor, a drive system, a pressure applying piece as well as a controller contained in the shell; the motor is connected to a battery in the shell or an external power source outside the shell; the drive system is connected between the motor and the pressure applying piece to convert a rotary movement of an output shaft of the motor into a linear movement of the pressure applying piece; the controller is connected to the motor to control operation / stalling of the motor and a rotation direction of the output shaft of the motor; and the rotary movement of the output shaft of the motor along first and second rotation directions leads to the linear movement of the pressure applying piece along the direction towards or far away from the vessel.
