4. Description of Creation (1) [Technical Field] The present invention relates to a tourniquet, particularly a controllable tourniquet that improves patient's discomfort and maintains the effectiveness of the tourniquet by improving its finger pressure structure. [Prior art]

The tourniquet was invented by Esmacher in 1886. At first it was a rubber tube, which was mainly used for rupture of large arterial blood vessels. It was not used in other cases to stop bleeding. When using a tourniquet, it should be tied above the bleeding wound on the extremities (to stop the bleeding), the affected limb should be raised for several minutes in advance, and a towel or its soft tissue should be placed on the part to prevent tissue abrasion. After the tourniquet is used, the blood supply to the tissue below the ligature site is interrupted, which can easily cause tissue ischemia and necrosis for a long time. Therefore, the time to tie the tourniquet should not be too long. It should be relaxed every 30 minutes, about half to one minute To make blood circulate. For this reason, the place where the tourniquet is used should be clearly marked, indicating the time when the tourniquet is tied, so that it can be transferred, and the receiving unit can relax by referring to this mark and take necessary treatment.

In addition to the use of tourniquets for emergency hemostasis, it has also evolved into a tourniquet for intravenous injections or blood draws. The main use of a tourniquet on the limb above the injection site can make the venous blood vessels that are not obvious appear under the skin. Use the vein at the injection point below the tourniquet. The vein is blood returning to the heart. It is affected by the compression of the tourniquet. The vein is deformed by an applied pressure. The cross-sectional area of the jk tube is reduced and blood flow is blocked. Because the pressure of the vein increased and the blood vessels expanded locally, the veins appeared under the skin. When using a tourniquet to assist injection, the traditional tourniquet is a slender rubber round tube. When used, the rubber round tube is usually pulled directly to a position, often during the pulling process, which also affects the skin, which will make the patient feel uncomfortable. And tourniquet

M248408 IV. Creation instructions (2) The injection needle is often punctured when loosening, which increases the patient's pain. At the end of the injection or blood drawing, the needle is usually pulled out and a hemostatic cotton ball is used to directly pressure the place. To achieve the effect of hemostasis, and this way also allows medical staff to have access to the patient's blood, increasing the risk of infection. Therefore, the creator disclosed a controllable tourniquet structure in the patent case of the Republic of China Patent Publication No. 0195523 4. This new type proposes a solution to the traditional rubber round tube for skin pulling and needle puncture; as shown in Figure 1 As shown, the tourniquet uses a flat long elastic band 1 and a set of fine-adjusting fasteners 2 and a finger pressing member 3 to use the fine-adjusting fasteners to adjust the elasticity of the elastic band 1; Pressing the Shiatsu member Γ Er Xun as the medical staff to use the Shiatsu member 3 to press the dust injection part to stop the movement of Zhiyong Λ Ding through the Shiatsu member 3, which can be applied to different patients . However, the creator used the new type = there are still some problems with the new type, that is, the fine adjustment of the fasteners Ϊ:: f skin caused the patient's discomfort due to pulling, but there is a problem in the design of the finger pressure member 3, which must be used again in use Hemostatic effect can be achieved by applying an external force to press the pressure member 3, and the average blood clotting time of ordinary people is about 30 to 60 minutes per day, while patients with hemophilia or patients with abnormal liver function have abnormal platelet metabolism in the blood. The blood coagulation time is longer, so applying force to the finger pressing member 3 for a long time will cause a distress to the medical staff or the patient. [Content] The main purpose of this type is to change the design of the acupressure member so that it can be fixed simultaneously with a tourniquet during long-term compression and hemostasis. Another purpose of this new model is to avoid skin damage during tourniquet adjustment.

The two ends of the finger-pressing member and the button are respectively pressed by a knob. When the knob is moved up and down, the fingertip structure will not affect the skin, and the skin will be in contact with the skin. Therefore, when the knob is turned, the fixing members at both ends of the fingertip member can be = :, and will not cause the patient Discomfort, when positioning, you can adjust by level =: adjustment 'tourniquet pull to-amplitude adjustment. It must be known that the fixing parts on both sides of the pressing member are made a small [implementation method] The details # about this new model are as follows: 月 月 and technical content, now with the illustration of the schematic diagram, J is installed. The appearance of the new and preferred embodiment is different from that of a fixed part 4 (^ is shown at both ends of the finger pressing member 3), the car, the dagger, the tail end 41 of the fixed part 4, and the elasticity. The belt (not shown in the figure is pulled and the heart pressure member 3 is provided with a plurality of hole grooves 30 on both sides, which can be used to fix the end of the 49 area 42 in the hole groove 30 to adjust. When the pivot end is to be adjusted, the drag The terminal 4 2 is pulled out on both sides, and the pivoting terminal 4 2 can be moved in the water in the slot 30. When the positioning is adjusted to a certain position, the pivoting terminal 4 2 is pushed back to fit lightly with the slot 3. 'And the fixing member 4 is provided with a square engaging groove 44 and an engaging portion 4 3 1 of an oval piece 43 connected to each other, and the engaging portion 4 3 1 of the oval piece 4 3 is in the square engaging groove 4 4 of the fixing piece 4 It is in an adjustable state. The elliptical piece 43 is used to fix the limb. The distance between the two fixing members 4 and the elliptical piece 43 can be adjusted according to the size of the fixed limb.
