5. Precautions and suggestive instructions
5.1 Potential hazards and restrictions on use
5.1.1 This product is a single-use device. After the expiration date, it cannot be used normally, and after use, it should be disposed of in accordance with the country's existing medical waste safety management regulations.
5.1.2 This product is sterilized by ethylene oxide. If the inner packaging is damaged, please do not use it.
5.1.3 If the product cannot block the blood flow of the patient's limbs, it should be removed immediately.
5.1.4 The hemostasis time of this product should not exceed 90 minutes.
5.1.5 Do not place the elastic ring of this product on the elbow (where it is likely to cause damage to the ulnar nerve) or the knee (where it is likely to cause damage to the common peroneal nerve). Confirm that the circumference of the mid-upper part of the patient's upper arm is between 14-40cm and the middle thigh between 28-85cm. If the measured circumference exceeds the above range, please use other methods to conduct hemostasis. If the systolic blood pressure is higher than 180mmHg, please take other methods to conduct hemostasis.
5.2 Before using this product, the operator should read this manual carefully, be familiar with the performance and the use of the device.
5.3 It is recommended to use the device when the patient is under anesthesia. If not, the patient will feel uncomfortable. Explain to the patient before use.

6. Warnings
Possible adverse reactions
6.1.1 Numbness, edema, and hematoma at the site of hemostasis.
6.1.2 Skin ecchymosis, blisters and necrosis.
6.1.3 Ineffective hemostasis and worsening bleeding.
6.1.4 Tourniquet pain.
6.1.5 Tourniquet shock.
6.1.6 Muscle nerve injury.
6.1.7 Vascular damage, thrombosis.
6.1.8 Other complications of combined surgery.
6.2 The elastic contraction ring of this product must not roll to the distal end of the limb after reaching the working part.

8. Instructions

8.1 Measure the circumference of the patient's limb at the exsanguination site (mid-upper part of the upper arm; middle thigh). Confirm that the circumference is within the applicable range of Table 1. If it exceeds the above range, please use other methods to conduct hemostasis.
8.2 Take out the product according to the aseptic procedure in the operating room and then place it on the table. Ensure that the plastic card is available at the end of the operation.
8.3 Disinfect the limb up to the mid-upper part of the upper arm or above the middle thigh depending on the surgical site and use a sterile transparent drape to cover the edge of the disinfected area.
8.4 Product application
8.4.1 Upper limb type: If the patient is conscious, ask the patient to gather the fingers together. If the patient is unconscious, the assistant (wearing sterile gloves) should hold the patient's fingers together, squeeze them into the ring (the handles facing away from the patient) and pull the handles to the proximal end, while the other assistant (wearing sterile gloves) grasps the end of the limb to fight against the traction, so that the device could scroll up to the proximal end smoothly.
8.4.2 Lower limb type: the assistant (wearing sterile gloves) should squeeze the patient's toes into the ring (the handles facing away from the patient), and pull the handles to the proximal end, while the other assistant (wearing sterile gloves) grasp the end of the limb to fight against the traction so that the device could scroll up to the proximal end smoothly.
8.4.3 Pull the handles until the elastic ring is on the surgical site: 10cm above the wrist joint or the mid-upper part of the upper arm; 5-15cm above the lateral malleolus that is below the calf muscle, or the middle of the thigh. The device should be kept within the disinfection area.
8.5 Use sterile injection water or 0.9% injection sodium chloride to infiltrate the elastic sleeve at the surgical site and then cut it. Wetting the sleeve before cutting can minimize fabric fragments. The surgical site can be covered with a sterile transparent drape.
8.6 When the operation is over, insert the plastic card from the distal end under the elastic ring, and cut the ring with a scalpel. Use scissors to cut up the sleeve and remove it from the patient's limbs. At this time, blood circulation will be resuming. Hemodynamic changes should be paid attention to and treated in time.

9. Storage and transportation conditions
9.1 Storage: The product should be placed in a clean room with a relative humidity of no more than 80% RH, no corrosive gas, and good ventilation.
9.2 Transportation: During transportation, the packaging must neither be bumped nor be exposed to rain.

10. Technical Principles
The diameter of the elastic ring is smaller than the minimum size of the limb (even the extremity). When the limb is inserted into the ring, the ring will be expanded, therefore exerts a counter-effect on the limb, squeezing the blood out of vessels. In order to generate enough force to resist the blood pressure, in the meantime not to generate excessive force to damage the tissues, the material of the ring must be selected reasonably.
