Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a disposable self-destructing needle-puncture-proof dispensing device. Background Technology

[0002] During medication preparation, reusing medication preparation devices or syringes cannot ensure that there is no residual medication inside the device. Reusing different medications may cause physicochemical reactions such as neutralization, hydrolysis, and destruction, and may even lead to drug allergic reactions in patients. Furthermore, reuse can accumulate infusion microparticles, which are non-metabolizable particulate impurities in infusion fluids. When the needle repeatedly punctures the rubber stopper of the medication bottle, it is easier to generate infusion microparticles. If patients receive a large amount of fluid containing insoluble microparticles, it may lead to phlebitis, vascular embolism, infarction, granuloma, and pyrogenic reactions.

[0003] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings and defects of the existing technology by providing a disposable, self-destructing, needle-puncture-proof dispensing device to solve the aforementioned problems.

[0005] The technical problem to be solved by this utility model can be achieved by the following technical solution:

[0006] A disposable, self-destructing, needle-puncture-proof dispensing device, characterized in that it comprises:

[0007] Sliding top cover;

[0008] An upper needle is disposed at one end of the upper cover and used for piercing the vial;

[0009] An elastic element disposed on the upper cover and used to trigger the self-destruction action of the upper needle;

[0010] A lower cover that provides a sliding fit with the upper cover;

[0011] A lower needle is disposed at one end of the lower cap and used to puncture another vial;

[0012] A retrieval cavity is provided on the lower cover for retrieving the upper needle.

[0013] In use, the upper needle of the top cap pierces the upper vial, and the lower needle of the bottom cap pierces the lower vial. The medication in the upper vial then flows through the upper needle into the lower vial for mixing. After mixing, sliding the top cap will trigger the upper needle to self-destruct when the elastic element reaches the retrieval cavity of the lower cap. At this time, the upper vial should be aligned with the waste medical device collection box. When self-destruction is triggered, the upper vial will automatically fall due to the retrieval of the upper needle. After self-destruction is complete, gently shake to mix the medication, and then have a nurse draw out the mixed medication using a syringe.

[0014] In a preferred embodiment of this utility model, the other end of the top cover is provided with a handle for easy pushing and pulling.

[0015] In a preferred embodiment of the present invention, one end of the top cover is further provided with a platform for horizontal placement of the vial and located at the puncture site of the upper needle.

[0016] In a preferred embodiment of this utility model, the other end of the lower cover is provided with a Luer connector for docking with a syringe.

[0017] In a preferred embodiment of the present invention, a sealing component is further provided at one end of the lower cover.

[0018] In a preferred embodiment of the present invention, the sealing component is an O-ring fitted on the lower cover.

[0019] In a preferred embodiment of this utility model, the bottom of the lower cover is provided with a hoop for fixing the vial.

[0020] In a preferred embodiment of this utility model, the elastic element is a spring.

[0021] In a preferred embodiment of this utility model, the upper needle and the lower needle are made of non-metallic injection molding.

[0022] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: This utility model achieves the purpose of preventing needle pricks by using disposable needles and using non-metallic needles instead of metal needles. Moreover, when this utility model is used, the nurse pushes the upper cover and activates the spring, which in turn springs the upper needle into the recycling cavity of the lower cover. At the same time, the nurse can use a syringe to draw up the mixed medicine solution. The O-ring can also play a good role in sealing between the upper and lower covers. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0029] See Figures 1 to 4 The disposable, self-destructive, needle-proof dispensing device shown includes an upper cover 10, an upper needle 20, an elastic element 30, a lower cover 40, a lower needle 50, and a recovery cavity 60. In this embodiment, the upper needle 20 and the lower needle 50 are made of non-metallic injection molding.

[0030] The upper cover 10 is slidably mounted on the lower cover 40, while the upper needle 20 is located at one end of the upper cover 10 and is used to puncture the vial above.

[0031] An elastic element 30 is disposed on the upper cover 10 and is used to trigger the self-destruction action of the upper needle 20. In this embodiment, the elastic element 30 is preferably a spring. Specifically, one end of the upper cover 10 has a cavity for energizing the spring 30 and the upper needle 20.

[0032] The lower cap 40 is provided, and the lower needle 50 is located at one end of the lower cap 40 and is used to puncture another vial.

[0033] The recovery cavity 60 is disposed on the lower cover 40 and is used to recover the upper needle 20. In this embodiment, the recovery cavity 60 is located at one end of the lower cover 40.

[0034] To facilitate operation by nurses, a handle 11 for easy pushing and pulling is provided at the other end of the top cover 10. In this embodiment, one end of the top cover 10 is also provided with a platform 12 for horizontal placement of the vial and located at the puncture site of the upper needle 20. The platform 12 can prevent the vial from tilting even when placed upside down.

[0035] To facilitate nurses' operation, a Luer connector 41 for docking with a syringe is provided at the other end of the lower cover 40. In this embodiment, a sealing component 42 is also provided at one end of the lower cover 40, which is preferably an O-ring embedded in the lower cover 40.

[0036] To secure the vial, a hoop 43 is provided at the bottom of the lower cap 40 for securing the vial.

[0037] In use, the upper needle 20 of the upper cover 10 punctures the upper vial, and the lower needle 50 of the lower cover 40 punctures the lower vial. The medication in the upper vial then flows through the upper needle 20 into the lower needle 50 and mixes with the medication in the lower vial. After mixing, the nurse pushes and pulls the upper cover 10. When the elastic element 30 reaches the recovery cavity 60 of the lower cover 40, it triggers the upper needle 20 to self-destruct. At this time, the upper vial should be aligned with the waste medical device storage box. When self-destruction is triggered, the upper vial will automatically fall onto the platform 12 due to the recovery of the upper needle 20. After self-destruction is triggered, the medication is gently shaken to mix. The nurse then uses a syringe to align with the Luer connector 41 of the lower cover 40 for installation, and then draws out the mixed medication.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
