Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a medical chemical device that can replace traditional syringes for drug dissolution and preparation. Background Technology

[0002] Currently, clinical drug preparation primarily relies on traditional syringes for dissolving and transferring drugs. This method has several drawbacks:

[0003] 1. Repeated puncture of the stopper: Traditional needles need to be repeatedly punctured into the stopper of the medicine bottle, which can easily cause stopper debris to contaminate the medicine.

[0004] 2. Occupational safety issues: Traditional metal needles may cause puncture wounds to medical staff during insertion and removal, increasing the risk of infection.

[0005] 3. Drug loss and environmental pollution: Due to the large puncture diameter of the needle, drug leakage may occur, affecting drug utilization and polluting the environment.

[0006] 4. Without an air intake channel, the negative pressure during the solution preparation process cannot be controlled, making it easy for the solution to overflow and potentially causing the syringe and vial to detach.

[0007] Currently, there is no device that can fully solve the above problems and is easy to use. Summary of the Invention

[0008] To address these problems in the prior art, this utility model provides a novel dispensing device. This device adopts an integrated molding design, incorporates a liquid storage bag, uses a non-sharp needle, and combines a cross-shaped concave handle to improve dispensing safety and ease of operation.

[0009] The device includes:

[0010] Bottle needle (1) and liquid bag (2): The two are connected as one unit to improve the sealing and reduce the risk of liquid leakage.

[0011] Connecting part (3): The end of the bottle needle is provided with a conical male head, which can be directly inserted into the opening of the liquid bag to form a tight connection.

[0012] Threaded connection method: The connecting part (3) of the bottle needle (1) can also be provided with an integrally formed external thread, which matches the integrally formed internal thread inside the opening of the liquid bag (2) to achieve a more secure connection.

[0013] Dual-channel structure: The syringe (5) is equipped with an air intake channel (7) and a liquid delivery channel (8) to ensure smooth delivery of the drug and balance the pressure inside the bottle.

[0014] Air filtration system: The air inlet (9) of the air intake pipe (7) is located on the side wall of the needle tube, and the air outlet (10) is located on the side wall near the needle (4). An air filter membrane is installed inside the air inlet to effectively prevent external pollutants from entering and ensure the safety of the medicine.

[0015] Cross-shaped handle (6): Ergonomically designed for easy hand holding and dispensing, improving operational stability.

[0016] Non-sharp needles (4): The needle diameter is set at 3-5mm to reduce occupational injuries, while still being able to pierce the bottle stopper smoothly.

[0017] The components of this invention are integrated and connected, making it easy to operate and use. It has a simple structure, low cost, and is very suitable for clinical use. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This embodiment provides a device suitable for chemical drugs, the structure and function of which conform to the above claims. This embodiment describes the specific usage method of this utility model's medical chemical drug device in a hospital dispensing scenario.

[0027] (1) Equipment preparation 1. Remove the medical chemical device, including the vial needle (1) and the liquid bag (2). 2. Ensure that the needle (4) of the vial is sterile and check that the air filter membrane (6) is intact.

[0028] (2) Medication preparation process 1. Before dispensing the medication, the operator wipes the surface of the vial stopper with disinfectant to ensure sterility. 2. Insert the needle (4) of the vial needle (1) vertically into the vial stopper, ensuring that the liquid delivery channel (8) inside the needle tube (5) is unobstructed after penetrating the stopper. 3. Gently squeeze the liquid bag (2) to allow the solvent to enter the vial through the liquid delivery channel (8) and the drug to dissolve fully. 4. After the medicine is prepared, adjust the angle of the vial needle (1) to allow the medicine to flow back smoothly into the liquid bag (2) and ensure that the medicine is transferred cleanly without any residue. 5. Ensure pressure balance inside the bottle through the air intake pipe (7) and filter membrane (6) to avoid splashing.

[0029] (3) Equipment removal and handling 1. Slowly pull out the vial needle (1) to avoid leaving any medicine residue on the stopper surface. 2. After taking it out, immediately seal the opening of the liquid bag (2) to prevent contamination or leakage of the medicine. 3. Dispose of used vials in accordance with medical waste management regulations (1).
