The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0033] Freeze-dried mitomycin C has high stability and can be quickly reconstituted in organic solvents to form a solution for injection into the human body. However, the current freeze-dried mitomycin C injection preparation lacks dedicated preparation tools. When non-medical personnel prepare it, it is not only easy to contaminate the drug solution, but also insufficient dissolution will lead to its efficacy not being fully exerted.

[0034] In view of this, the utility model provides a drug dispensing device for mitomycin lyophilized powder. Figure 1-6 For an embodiment of the drug dispensing device for mitomycin lyophilized powder provided by the utility model, please refer to Figure 1-6 The drug dispenser 100 for mitomycin lyophilized powder includes a container 1 , a drug-filled component 2 and a cover plate 3 .

[0035] The container 1 is cup-shaped, with an opening 1a on the top, an injection port 1c for inserting a syringe on the side wall of the container 1, a medicine-filled part 2 is movably arranged at the opening 1a, and has a sink 21 arranged inside the container 1 for placing freeze-dried powder, and a cover plate 3 is movably connected to the container 1, and is used to open or close the opening 1a to prevent the medicine from splashing out from the opening 1a during injection. When the medicine-filled part 2 moves, the groove wall of the sink 21 can open or close the injection port 1c, and the movement here can be either circumferential rotation, or up and down, left and right movement, or a combination of multiple movements. The way the cover plate 3 is connected to the container 1 can be hinged, snap-fitted, etc. This embodiment is a hinged relationship, which can make the cover plate 3 open or close, and will not be described in detail here; the cover plate 3 and the container 1 have an interlocking snap-fit ​​structure (not shown in the figure) to prevent the cover plate 3 from being opened at will.

[0036] In the technical solution of the utility model, by movably installing the medicine-filling part 2 at the opening 1a of the container 1, and making the injection port 1c of the container 1 open and connected to the inside of the container 1, the syringe can inject a solvent to dissolve the lyophilized powder in the medicine-filling part 2, and the medicine-filling part 2 continues to move to close the injection port 1c to prevent the incompletely dissolved liquid medicine from flowing back into the syringe. The device can close the injection port 1c when configured, and open the injection port 1c after the dissolution is completed, effectively preventing the liquid medicine from flowing back into the syringe, so that its drug efficacy can be guaranteed.

[0037] In addition, after the syringe is inserted into the injection port 1c, it does not need to be pulled out until the freeze-dried powder is completely dissolved, and then the solution is drawn out, thereby avoiding contamination of the syringe and the external environment.

[0038] To ensure adequate contact between the lyophilized powder and the solvent, please refer to Figure 5 and Figure 6In one embodiment of the utility model, a first through hole 2a is provided on the side wall of the sink 21. When the medicine-filling member 2 moves relative to the container 1, the first through hole 2a can be connected to the injection port 1c. When the syringe is inserted into the injection port 1c, the medicine is sprayed onto the freeze-dried powder in the sink 21 through the first through hole 2a, thereby accelerating the dissolution rate of the freeze-dried powder.

[0039] To allow the dissolved solution to enter container 1, refer to Figure 4 and Figure 5 In one embodiment of the present utility model, a second through hole 2b is provided on the bottom wall of the sedimentation tank 21, and the prepared solution enters the container 1 through the second through hole 2b.

[0040] In order to enable the medicine-filling member 2 to move relative to the container 1, please refer to Figure 3-6 In one embodiment of the present invention, a matching portion 11 is provided on the end surface of the outer periphery of the opening 1a, and the medicine-filling member 2 is correspondingly provided with a sliding portion 22 that slidably matches the matching portion 11. It should be noted that when the medicine-filling member 2 slides relative to the container 1, the sliding mode thereof can be longitudinal, transverse or circumferential.

[0041] For further information, see Figure 3-6 In one embodiment of the present invention, the sliding portion 22 and the matching portion 11 are both wedge-shaped structures with inclined surfaces, and when the medicine-filling member 2 rotates around the opening 1a, the sliding portion 22 slides relative to the inclined surface of the matching portion 11, so that the medicine-filling member 2 moves upward in a spiral, and the side wall of the sink 21 closes the injection port 1c. In addition, in order to prevent the sliding fit from failing during rotation, a mutual limiting structure is provided between the sliding portion 22 and the matching portion 11.

[0042] To make the action of the charge 2 smoother, please refer to Figure 5 and Figure 6 In one embodiment of the present invention, the matching portion 11 and the sliding portion 22 are provided in plurality and are evenly distributed along the circumference of the opening 1a. In this embodiment, three are preferred.

[0043] In order to facilitate the user to manually drive the medicine-filled member 2 to rotate, please refer to Figure 4-5 In one embodiment of the utility model, a plurality of rack-shaped anti-skid ribs 23 are provided on the outer periphery of the medicine-filling member 2, which increases the friction between the hand and the medicine-filling member 2. The user manually pushes the anti-skid ribs 23 on the medicine-filling member 2, thereby driving the medicine-filling member 2 to rotate.

[0044] To prevent leakage from the syringe during injection, refer to Figure 1 and Figure 6 In one embodiment of the present invention, the injection port 1c is a tapered port with a diameter gradually increasing from the inside to the outside, so that the port of the syringe can be tightly connected to the injection port 1c.

[0045] To prevent the medicine-filled component 2 from falling during the upward rotation, please refer to Figure 5 and Figure 6 In one embodiment of the utility model, an arc-shaped bayonet 1b is provided on the end surface of the outer periphery of the opening 1a, and a buckle 24 is correspondingly provided on the medicine-filling member 2 to be clamped on the bayonet 1b. The design of the buckle 24 limits the height of the medicine-filling member 2 and the arc of rotation, and effectively prevents the medicine-filling member 2 from falling off. It should be understood that the buckle 24 can move circumferentially along the bayonet 1b, and the arc of the bayonet 1b is the rotation range of the medicine-filling member 2.

[0046] For better limiting effect, please refer to Figure 5 and Figure 6 In one embodiment of the present invention, the bayonet 1b and the buckle 24 are provided in plurality and are evenly distributed along the circumference of the opening 1a. Preferably, the bayonet 1b and the matching portion 11 are arranged close to each other, and the buckle 24 and the sliding portion 22 are arranged close to each other, and the number of the two corresponds to each other.

[0047] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
