Background

Fibrin adhesives, also known as Fibrin glues, bio-protein glues (British name Fibrin Sealant or Fibrin glue), are commonly used medically to treat bleeding from incised wounds. The main action mechanism is that the fibrinogen is hydrolyzed into insoluble fibrin under the catalysis of thrombin, and forms a firm fibrin network structure under the action of blood coagulation factor XIII, and the fibrin network structure can be quickly adhered after covering the wound surface, thereby playing the roles of stopping bleeding, adhering and sealing the wound surface. Among them, the adhesive strength and hemostatic effect of a fibrin adhesive are closely related to the concentration of fibrinogen, and increasing the protein concentration of a fibrinogen solution is limited by many technical conditions, so that it is best to change the concentration of fibrinogen by changing the volume ratio of the fibrinogen solution and the thrombin solution.

Thus, when the first syringe 21 and the second syringe 22 are detached from the duplex base 10, the first piston rod 42 and the second piston rod 43 are respectively removed from the first groove and the second groove, and then are respectively used for sucking the fibrinogen solution and the thrombin solution, after a sufficient amount of suction, the first syringe 21 and the second syringe 22 are mounted on the duplex base 10, the first piston rod 42 is clamped in the first groove, the second piston rod 43 is clamped in the second groove, when the pushing part 41 is pushed with force, the pushing part 41 and the push-pull rod 45 move towards the direction close to the syringe assembly 20, during the process, the moving direction of the push-pull rod 45 penetrating through the fixing part 44 is limited by the through hole formed in the fixing part 44, and only can move slowly along the direction parallel to the axial direction of the syringes, so as to limit the movement of the pushing part 41, and the pushing part 41 drives the first piston rod 42 and the second piston rod 43 to move towards the first liquid outlet 212 and the second liquid outlet 222 smoothly, so that the fibrinogen solution in the first syringe 21 and the thrombin solution in the second syringe 22 smoothly flow out from the respective liquid outlet ports.

Further preferably, the duplex base 10 has an inverted Y-shaped bracket 5, so that the liquid outlet structure 30 of the duplex dispensing apparatus faces upward when the duplex dispensing apparatus is placed on a horizontal table, and the liquid outlet structure 30 of the dispensing apparatus faces upward in the gap between uses, thereby preventing the fibrinogen solution and the thrombin solution remaining in the three-way structure 31 from leaking out of the spray head 32. The liquid outlet structure 30 and the duplex base 10 are integrally formed to simplify the manufacturing process.

It should also be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

To sum up, the utility model provides a pair medicine dispenser can improve the fibrinogen concentration in the fibrin adhesive that its configured, reinforcing adhesive strength and hemostatic effect have higher application and popularization value.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
