Problems solved by technology

[0004] Purpose of the invention: The purpose of the present invention is to provide a compound microfluidic channel drug-loaded airbag hemostatic device and its use method. By inserting the drug-loaded airbag into the wound, the wound is compressed to stop bleeding; the drug enters through the injection hole, and finally passes through the infiltration The flow holes deliver the drug to the surface of the wound to achieve secondary hemostasis, which solves the problem that it is impossible to quickly stop the bleeding of wounds of different depths in an emergency

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0029] Such as figure 1 As shown, a composite microfluidic channel drug-loaded airbag hemostatic device of the present invention includes a drug-loaded airbag 1 and a check valve 2, and the drug-loaded airbag 1 and the check valve 2 are connected in series.

[0030] Such as Figure 2 to Figure 4 As shown, a central hole 11 is provided at the center of one end of the drug-loaded airbag 1, and a boss 12 is provided along the length direction of the drug-loaded airbag 1 on the side of the end of the drug-loaded airbag 1 where the center hole 11 is located. The drug injection hole 13 is connected with the joint of the syringe 4 through the drug-loaded tube 3, and the syringe 4 can inject the hemostatic drug into the drug-filled hole 13 through the drug-loaded tube 3; There are 4 annular drug-loading chambers 14. The drug-loaded airbag 1 and the annular drug-loa...

Abstract

The invention discloses a compound micro flow channel medicine-loading air bag hemostatic device and a using method thereof. The device comprises a medicine-loading air bag and a non-return valve, wherein the center of one end of the medicine-loading air bag is provided with a central hole; a boss is arranged at the end part, with the central hole, of the medicine-loading air bag in the longitudinal direction of the medicine-loading air bag; a medicine injecting hole is formed in the boss. The method comprises the steps that the medicine-loading air bag is inserted into a wound, gas enters aninner cavity of the medicine-loading air bag through the non-return valve, the medicine-loading air bag expands for hemostasis by compression on the wound; a medicine flows to each annular medicine-loading chamber via a first channel, and is conveyed to the surface of the wound via transfusion through holes to achieve secondary hemostasis. The device has the advantages of simple structure, simpleoperation and the like, and is particularly suitable for wounds of different depths, has the function of secondary hemostasis, and has high promotion value.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a composite microfluidic channel drug-loaded air bag hemostatic device and a method for using the same. Background technique [0002] In daily life, the wounds caused by the huge impact of sharp objects are generally irregular in shape, even passing through the ends of the limbs, and often cause a lot of bleeding. If not treated in time, the wounded will suffer from shock and even casualties due to excessive blood loss. The main means of hemostasis to this type of wound at present has the method for tourniquet and packing hemostasis. The tourniquet achieves the effect of hemostasis by compressing the blood vessels into an obstructed state, but prolonged blood stasis may lead to necrosis of the distal extremities. Packing hemostasis achieves the purpose of hemostasis by filling the penetrating wound with cotton fabric, but cotton fabric will absorb a large amount of bloo...
