There are three types of<unk> s: surgical<unk> s, emergency<unk> s, and rehabilitation<unk> s. A<unk>  is used by the phlebotomist to assess and determine the location of a suitable vein for venipuncture Surgical<unk> s<unk> <unk>  cuff with a releasable application handle stabilizer Silicone ring<unk> s, or elastic ring<unk> s, are self-contained mechanical devices that do not require any electricity, wires or tubes. The<unk>  comes in a variety of sizes. To determine the correct product size, the patient's limb circumference at the desired occlusion location should be measured, as well as their blood pressure to determine the best model. Once the correct model is selected, typically two sterile medical personnel will be needed to apply the device. Unlike with the pneumatic<unk> , the silicone ring<unk>  should be applied after the drapes have been placed on the patient. This is due to the device being completely sterile. The majority of the devices require a two-man operation (with the exception of the extra large model): # One person is responsible for holding the patient's limb, the other will place the device on the limb (with the extra-large there are two people needed). # Application: ## Place the elastic ring<unk>  on the hand/foot. Take care to ensure that all the fingers/toes are enclosed within the device. ## The handles of the<unk>  should be positioned medial-lateral on the upper extremity or posterior-anterior on the lower extremity. ## The person applying the device should start rolling the device while the individual responsible for the limb should hold the limb straight and maintain axial traction. ## Once the desired occlusion location is reached, the straps can be cut off or tied just below the ring. ## A window can be cut or the section of stockinet can be completely removed. ## Once the surgery is completed the device is cut off with a supplied cutting card. The elastic ring<unk>  follows similar recommendations noted for pneumatic<unk>  use: # It should not be used on a patient's limb for more than 120 minutes. # The<unk>  should not be placed on the ulnar/peroneal nerve. # The silicone ring device cannot be used on patients with blood problems such as DVT, edema, etc. # A patient suffering from skin lesions or a malignancy should use this type of<unk> . In knee replacement The current body of evidence suggests if a<unk>  is used in knee replacement surgery, it probably increases the risk of severe side effects and postoperative pain. The evidence did not show any clear benefit on patient function, treatment success, or quality of life. Emergency<unk> s Silicone ring auto-transfusion<unk>  The silicone ring auto-transfusion<unk>  (SRT/ATT/EED), or surgical auto-transfusion<unk>  (HemaClear), is a simple to use, self-contained, mechanical<unk>  that consists of a silicone ring, stockinet, and pull straps that results in the limb being exsanguinated and occluded within seconds of application. The<unk>  can be used for limb procedures in the operating room, or in emergency medicine as a means to stabilize a patient until further treatment can be applied. Combat application<unk>  The combat application<unk>  (CAT) was developed by Ted Westmoreland. It is used by the U.S. and coalition militaries to provide soldiers a small and effective<unk>  in field combat situations. It is also used in the UK by NHS ambulance services, along with some UK fire and rescue services. The unit utilizes a windlass with a locking mechanism and can be self-applied. The CAT has been adopted by military and emergency personnel around the world.
