Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a distal radial hemostat. Background Art

[0002] Compression hemostats are medical devices used to control bleeding and stop blood flow. They are primarily used in emergency, surgery, and other medical procedures to avoid the serious consequences of excessive blood loss. Compression hemostats work by applying pressure to create pressure on the bleeding site, helping to stop bleeding while stopping blood flow to the area.

[0003] Patent No. CN113545819 discloses a spiral compression hemostat with a safety lock, including a compression plate, a slider, a buckle, a mounting plate and a fixing belt. The outer side of the slider is sleeved with an adjusting knob, and the adjusting knob is threadedly connected to the slider; a mounting hole is provided on the mounting plate, and the slider can be slid up and down in the mounting hole, and a limiting groove is provided above the mounting hole and located on the outer side of the mounting hole. The first limiting boss at the bottom of the adjusting knob is embedded in the limiting groove. A notch is provided at the edge of the mounting plate, and the buckle can be detachably arranged at the notch. A plurality of first positioning teeth are provided on the buckle, and a plurality of second positioning teeth are provided at the bottom of the adjusting knob, and each second positioning tooth can mesh with the corresponding first positioning teeth. The compression plate is located below the mounting plate and is connected to the bottom of the slider; the two ends of the fixing belt are respectively connected to the mounting plate.

[0004] The above patented product is used for radial artery compression hemostasis, and can only perform puncture hemostasis on the radial artery. The location of the radial artery puncture point is generally at the wrist of the arm. However, if the distal radial artery is punctured for hemostasis, the distal radial artery puncture point is set on the back of the hand near the thumb. Since the fingers and wrist joints are often active and cannot be properly worn, it is difficult to stop bleeding at the puncture point on the back of the hand, which greatly limits the scope of application of the hemostat.

[0005] During the bleeding process, it is necessary to loosen the knob slightly at intervals to relieve the patient's pain. The rotation of the adjustment knob of the above existing hemostat depends on the personal experience of medical personnel and cannot achieve scientific and reasonable precise control.
