Abstract
A hemostatic device has a band for being wrapped around a puncture site P of a wrist W, securing means for securing the band in a state where the band is wrapped around the wrist, an inflation portion that interlocks with the band, and that is inflated by injecting gas, and an injection portion that can inject gas into the inflation portion. The injection portion is disposed in the band, and is foldable so as to decrease a space formed inside the injection portion. The hemostatic device can thus inflate an inflation portion without using a separate dedicated instrument, which can prevent a hemostasis-requiring site from being unintentionally compressed more than necessary.
Claims20
A hemostatic device comprising:
- a band for being wrapped around a hemostasis-requiring site of a limb;
- securing means for securing the band in a state where the band is wrapped around the limb;
- an inflation portion that interlocks with the band, and that is inflated by injecting gas;
- and
- an injection portion that can inject gas into the inflation portion,
- wherein the injection portion is disposed on the band, and is configured to be foldable so as to decrease a space formed inside the injection portion.
A hemostatic device comprising:
- a band adapted to be wrapped around a limb of a patient at a site on the limb where bleeding is to be stopped;
- securing means for securing the band in a wrapped state around the limb;
- an inflation portion disposed on an inner peripheral surface of the band, and adapted to be inflated by injecting gas;
- and
- an injection portion adapted to inject gas into the inflation portion,
- wherein the injection portion is configured to be foldable so as to thereby decrease an accommodation space formed inside the injection portion and the injection portion includes a securing mechanism adapted to maintain the injection portion in a folded state.
A method for performing hemostasis on a puncture site of a blood vessel of a patient's limb, the method comprising:
- securing a band of a hemostatic device on a patient's limb, the hemostatic device including the band for being wrapped around the limb of the patient at a site on the limb where bleeding is to be stopped, securing means for securing the band in a state where the band is wrapped around the limb, an inflation portion that interlocks with the band, and that is inflated by injecting gas, and an injection portion adapted to inject a gaseous substance into the inflation portion;
- when the band of the hemostatic device is worn on the patient's limb in a state where the inflation portion is not inflated, causing an introducer sheath to indwell the puncture site;
- aligning the inflation portion with the puncture site so that the inflation portion covers the puncture site;
- folding the injection portion so as to decrease a space formed inside the injection portion and thereby injecting the gas contained within the injection portion into the inflation portion to inflate the inflation portion;
- and
- in a state where the inflation portion is inflated, applying a compressing force to the puncture site by the inflation portion.
