It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

1 and 2, FIG. 1 is a preferred embodiment of a gas barrier sealing device applied to an inflatable tourniquet of the present invention. FIG. 2 is a schematic cross-sectional view of the gas barrier sealing device applied to the inflatable tourniquet along the line A-B.

[0016] In the present embodiment, the gas barrier sealing device 100 applied to the inflatable tourniquet includes a fixed strip 1 and a rotating bead 5. The upper side of the fixed strip 1 is provided with a card slot 2, which is a U-shaped groove, and the length of the card slot 2 matches the length of the fixed strip 1 for placing the The bead 5 is rotated, the length of which is matched to the length of the fixed strip 1. One side of the card slot 2 is provided with a first silicone strip 3 and the other side is provided with a second silicone strip 4. The first silicone strip 3 and the second silicone strip 4 are deformed by the air pressure in the inflation tourniquet 11 (shown in Fig. 3), and the inflation tourniquet 11 can be pressed and sealed.

[0017] One end (for example, the right end) of the fixed strip 1 is provided with a card end 6 , and the other end of the fixed strip 1 (for example, the left end) is provided with a fixed end 7 , and the fixed end 7 is provided with Rotate the pin 8. One side of the card end 6 is provided with a positioning knob 9, and the other side is provided with a positioning bead 10. One end (for example, the left end) of the rotating bead 5 is fixed to the fixed end 7 by a rotating pin 8, and the other end (for example, the right end) of the rotating bead 5 is in contact with the card end 6 Both ends of the inflatable tourniquet 11 are sealed and clamped in the card slot 2. In this embodiment, the left end of the rotating bead 5 can be rotated with the rotating pin 8 as a fulcrum. The left end of the rotating bead 5 rotates backward around the rotating pin 8, and the right end of the rotating bead 5 falls on the fixed strip 1. The card slot 2 is in contact with the card end 6 . When the right end of the rotating bead 5 contacts the card end 6 , the positioning bead 10 positions the right end of the rotating bead 5 to the card slot. 2, the user can manually rotate the positioning knob 9 to lock the right end of the rotating bead 5 in the card slot 2, so that both ends of the inflatable tourniquet 11 are sealed and clamped in the card slot In the second, the inflatable tourniquet 11 is automatically sealed and clamped without leaking, so that the air pressure in the tourniquet 11 can be stabilized to improve the hemostatic effect of the inflatable tourniquet 11, and the operation is convenient to meet the demand for rapid hemostasis.

[0018]

[0019] As shown in FIG. 3, FIG. 3 is a schematic plan view showing the use state of the gas barrier sealing device applied to the inflatable tourniquet of the present invention. In the present embodiment, the gas barrier sealing device 100 is applied to the inflatable tourniquet 11, which is hermetically connected to the air bag 12 through the air guiding tube 15. The user can inflate the inflatable tourniquet 11 by pinching the balloon 12. The air bag 12 is a rubber capsule having an elliptical shape or a spherical shape. The inflatable tourniquet 11 has a non-encapsulated ribbon structure and has wear resistance, oil resistance, elasticity, etc. Features. The inner surface of the inflatable tourniquet 11 is coated with a gas-permeable silicone layer to increase the hermeticity of the inflatable tourniquet 11, and it is possible to prevent the inflation of the inflatable tourniquet 11 from causing gas leakage after inflation.

[0020] The air bag 12 is provided with an intake valve 13 and an exhaust valve 14. The intake valve 13 is used by the user to inflate the inflation tourniquet 11 with the air bag 12 to inhale the outside air. The exhaust valve 14 is for venting the inflatable tourniquet 11 and discharging the gas in the inflatable tourniquet 11. When the user inflates the inflated hemostatic band 11 by pinching the air bag 12, the exhaust valve 14 is in a closed state. The intake valve 13 and the exhaust valve 14 may be disposed at any position of the air bag 12, and in the embodiment, the intake valve 13 and the exhaust valve 14 are both disposed on the air bag 12 At the bottom, the user can inflate or deflate the inflatable tourniquet 11 by hand gripping the balloon 12.

[0021] After the inflation tourniquet 11 is inflated, the gas barrier sealing device 100 seals both ends of the inflatable tourniquet 11 by the fixed strip 1 and the rotating bead 5 so that the user can fix the inflatable tourniquet 11 Hemostasis is performed on the wound site where hemostasis is required. The gas barrier sealing device 100 can automatically seal and clamp the gas-filled tourniquet 11 without leaking, thereby maintaining the stability of the blood pressure in the tourniquet and improving the hemostatic effect, and the operation is convenient to meet the demand for rapid hemostasis.

[0022] In the use of the gas barrier sealing device 100 to clamp the inflatable tourniquet 11 for hemostasis, the user first puts the inflatable tourniquet 11 on the hemostatic site (such as the arm or leg) before inflating, and then inflates the blood to stop bleeding. Both ends of the belt 11 are overlapped and placed in the card slot 2 of the fixed strip 1. The user presses the right end of the rotating bead 5 so that both ends of the inflatable tourniquet 11 are caught in the card slot 2 of the fixed strip 1. The positioning bead 10 positions the right end of the rotating bead 5 into the card slot 2 so that the rotating bead 5 cannot be bounced, and the user manually rotates the positioning knob 9 to lock the right end of the rotating bead 5 to the card position. The inflatable tourniquet 11 is caught between the rotating bead 5 and the card slot 2 in the slot 2. Here, the user inflates the inflatable tourniquet 11 by inflating the balloon 12 to pressure the patient's blood port to stop bleeding. The deformation of the first silicone strip 3 and the second silicone strip 4 by the air pressure in the inflatable tourniquet 11 further deforms the inflated tourniquet 11 by a compression seal. When the bleeding is completed, the user slams the exhaust valve 14 to discharge the gas in the inflatable tourniquet 11. When the inflatable tourniquet 11 is to be removed, the inflatable tourniquet 11 can be removed from the gas barrier by simply loosening the positioning knob 9 and slamming the rotating bead 5 from the locking slot 2 of the fixed strip 1. The 100 is taken out, so that the user can conveniently clean the inflatable tourniquet 11 and carry it with him or her.

[0023] The above is only a preferred embodiment of the present invention, and thus does not limit the scope of the patent of the present invention, and the equivalent structure or equivalent function transformation made by the specification and the drawings of the present invention, or directly or indirectly In other related technical fields, the same is included in the scope of patent protection of the present invention.
