Description

Technical Field

[0001] This utility model relates to the technical field of sealing caps, and more specifically, to a dual-valve combination cap. Background Technology

[0002] Currently, most large-volume parenteral solutions store drugs in storage bottles. Existing storage bottles consist of a bottle body and a combination cap. The bottle body is made of various materials, such as plastic and glass, but the combination cap is mostly made of polymer materials such as plastic and rubber.

[0003] Combination caps typically consist of an outer cap, a gasket, and an inner cap, which work together. The inner cap has strict material requirements and is expensive. During assembly, the inner cap is prone to misalignment with the outer cap and gasket, leading to issues such as plug loss and leakage, affecting normal use. Furthermore, existing combination caps often feature an easily detachable valve (the outer cap is removed by pinching the valve), which can easily fall off during transportation and use, contaminating the gasket and compromising medication safety. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-valve combination cap, which can effectively avoid problems such as leakage, plug loss, and chipping caused by improper combination cap assembly.

[0005] This utility model is achieved through the following technical solution: The dual-valve combination cap of this utility model includes a cap body, an infusion tube disposed on the upper side of the cap body, a drug delivery tube disposed on the upper side of the cap body, a first pad disposed in the infusion tube, a second pad disposed in the drug delivery tube, and a first diaphragm for sealing the infusion tube; the first pad is engaged in the infusion tube, and the second pad is detachably connected to the drug delivery tube.

[0006] Furthermore, the inner wall of the dosing tube is provided with internal threads, and the outer wall of the second pad is provided with external threads; the dosing tube is threadedly connected to the second pad.

[0007] Furthermore, one end of the second pad is located inside the dosing tube, and the other end is located outside the dosing tube; the end of the second pad located inside the dosing tube has a groove.

[0008] Furthermore, a sleeve is fitted on the outer wall of one end of the second pad outside the dosing tube, and a second diaphragm is covered on the upper end of the sleeve.

[0009] Furthermore, the upper end of the infusion tube is bent inward and then attached to the first pad.

[0010] Furthermore, the inner wall of the infusion tube is provided with an annular limiting ring; the first pad is placed on the limiting ring.

[0011] Furthermore, the thickness of the edge of the first pad is greater than the thickness of the center.

[0012] The technical solution of this utility model has at least the following advantages and beneficial effects: In use, the dual-valve combination cap of this utility model allows for infusion by tearing open the first diaphragm and then directly inserting the puncture needle through the first pad. When medication is needed, a syringe can be used to insert the medication through the second pad, or the second pad can be removed directly, and the bottle and cap can be cleaned through the medication insertion tube. Furthermore, this device eliminates the need for an inner cap, thus avoiding problems such as leakage, cap loss, and puncture debris caused by improper assembly of the inner and outer caps. It also eliminates the valve plate, preventing medication contamination caused by the valve plate falling off during transportation and use. Attached Figure Description

[0018] Example

[0019] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 4As shown, the dual-valve combination cap of this embodiment includes a cap body 1, an infusion tube 2 disposed on the upper side of the cap body 1, a drug delivery tube 3 disposed on the upper side of the cap body 1, a first pad 4 disposed in the infusion tube 2, a second pad 5 disposed in the drug delivery tube 3, and a first diaphragm 6 for sealing the infusion tube 2; the first pad 4 is snapped into the infusion tube 2, and the second pad 5 is detachably connected to the drug delivery tube 3. Specifically, in use, the first diaphragm 6 is torn open, and then the puncture needle can be directly passed through the first pad 4 for infusion. When drug delivery is required, a syringe can be used to deliver the drug through the second pad 5, or the second pad 5 can be directly removed, and then the bottle body and cap body 1 can be cleaned through the drug delivery tube 3. Furthermore, this device does not have an inner cap structure, thus avoiding problems such as leakage, plug loss, and puncture debris caused by improper assembly of the inner and outer caps. Also, the valve plate is eliminated, avoiding the problem of drug contamination caused by the valve plate falling off during transportation and use.

[0020] In this embodiment, the inner wall of the dosing tube 3 is provided with internal threads, and the outer wall of the second pad 5 is provided with external threads; the dosing tube 3 and the second pad 5 are threadedly connected. Specifically, this makes it easier to remove the second pad 5 from the dosing tube 3.

[0021] In this embodiment, one end of the second pad 5 is located inside the drug delivery tube 3, and the other end is located outside the drug delivery tube 3; the end of the second pad 5 located inside the drug delivery tube 3 has a groove 7. Specifically, providing a groove 7 on the second pad 5 can reduce the thickness of the middle part of the second pad 5. This allows the puncture needle to be directly passed through the second pad 5 without removing the second pad 5, effectively reducing puncture debris.

[0022] In this embodiment, the second pad 5 is fitted with a sleeve 8 on the outer wall of one end outside the dosing tube 3, and a second diaphragm 9 covers the upper end of the sleeve 8. Specifically, the sleeve 8 facilitates manual rotation of the second pad 5 to remove it. The second diaphragm 9 seals the upper end of the second pad 5 to prevent contamination.

[0023] In this embodiment, the upper end of the infusion tube 2 is bent inward and then attached to the first pad 4. Specifically, the bending of the upper end of the infusion tube 2 can seal the first pad 4, improve the sealing effect, and prevent the first pad 4 from falling off. The first pad 4 can be inserted into the infusion tube 2, then the end of the infusion tube 2 can be heated and softened, and then the pressure can be reduced and pressed to deform it into a bent shape.

[0024] In this embodiment, the inner wall of the infusion tube 2 is provided with an annular limiting ring 10; the first pad 4 is placed on the limiting ring 10. Specifically, the limiting ring 10 can support the first pad 4.

[0025] In this embodiment, the thickness of the edge of the first pad 4 is greater than the thickness of the center. Specifically, the edge of the first pad 4 is thicker, resulting in a better sealing effect, while the center is thinner, allowing the puncture needle to penetrate more effectively.

[0026] In summary, the dual-valve combination cap of this embodiment allows for infusion by tearing open the first diaphragm 6 and then directly inserting the puncture needle through the first pad 4. When medication is needed, a syringe can be inserted through the second pad 5 for administration, or the second pad 5 can be removed directly, and the bottle and cap 1 can be cleaned via the medication insertion tube 3. Furthermore, this device eliminates the need for an inner cap, thus avoiding problems such as leakage, cap loss, and puncture debris caused by improper assembly of the inner and outer caps. The elimination of the valve plate also prevents contamination of the medication caused by the valve plate falling off during transportation and use.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
