Description

A semi-automatic tourniquet with a sphygmomanometer

technical field

The invention belongs to the technical field of tourniquets, in particular to a semi-automatic tourniquet with a sphygmomanometer.

Background technique

The use of the tourniquet has a history of more than 100 years. It was invented by Essmacher in 1886. It was originally a rubber tube, mainly used for larger arterial ruptures. It was used when other hemostasis methods were useless, but there were many risks. . Since the tourniquet is an indispensable equipment in the medical industry, especially in the ambulance, hand and foot trauma surgery, and orthopedics, and modern medical care has proved that: timely and reasonable use of the tourniquet will effectively reduce the risk of economic losses and casualties of patients, so medical work The author has been committed to the research and upgrade of the tourniquet.

After the continuous improvement of tourniquets, the tourniquets currently used in clinical emergency work are disposable tourniquets (or rubber tubes) and pneumatic tourniquets. Both tourniquets have good hemostatic effect, but there are many deficiencies, the main deficiencies are as follows: 1. Both are not easy to control the tightness of the tourniquet cuff, and the pressure is too large and the tourniquet is too tight. Damage to the skin, nerves, blood vessels and muscles at the site, and even cause necrosis of the extremities, which is not conducive to the recovery of the function of the affected limb. If the air pressure is too small, it can only compress the veins but not the arteries. 2. Since the tourniquet is not equipped with a corresponding timer, the time of use must be marked when using the tourniquet. The medical staff determines the duration of hemostasis by marking the time. When the marked time is lost or the medical staff forgets, it is easy to cause the patient The affected limb is oppressed for a long time, which leads to adverse consequences; 3. There is no corresponding gas flow control valve. When the tourniquet is loosened, due to the rapid release of gas in the tourniquet cuff, the blood vessels at the binding site stretch rapidly from the original compression state. It is easy to cause the patient to reduce the amount of blood returned to the heart, resulting in shock performance, and even death; 4. A separate sphygmomanometer or a separate tourniquet will be basically scrapped as long as a certain component is damaged. When it is in an emergency, the inability to use the equipment will delay the patient. time for diagnosis and treatment, putting patients at greater risk, and reducing medical equipment usage.
