An adjustable vascular compression device assists in achieving partial or full occlusion of a blood vessel when applied to a patient's limb, for example, during or following a medical procedure. Pads on the device apply preferential compression to portions of the circumference of the limb so as to enable blood flow through adjacent blood vessels during the compression period. Further, rapid fastening, tightening, loosening and release is enabled by a single mechanism, and gradual adjustments to the tightness may be made without releasing said mechanism.

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 invention discloses pneumatic automatic hemostasis equipment and a pneumatic automatic hemostasis method. The method includes the steps of starting a timer to compute hemostasis time of a tourniquet acting on a wound surface; controlling a miniature air pump to suck in air via air inlet holes to inflate the tourniquet and acquiring an air pressure value in the tourniquet by an air pressure sensor; when the air pressure value is smaller than a first preset value, continuing controlling the miniature air pump to suck in the air via the air inlet holes to inflate the tourniquet; when the air pressure value is larger than a second preset value, controlling the miniature air pump to deflate the tourniquet via air outlet holes; when the air pressure value is between the first preset value and the second preset value, judging whether the hemostasis time reaches preset time or not; when the hemostasis time reaches the preset time, controlling a loudspeaker to play voice information to inform medical personnel of checking hemostasis conditions of the wound surface. The pneumatic automatic hemostasis equipment and the pneumatic automatic hemostasis method have the advantages that the problems of poor hemostatic effects caused by too high or too low hemostasis pressure of the tourniquet acting on the wound surface and wound tissue necrosis caused by long-time continuous vascular compression can be avoided effectively.
