Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical care, and particularly relates to a conversion type bottle cap for an infusion bottle. Background Art
[0002] An infusion bottle is a bottle used to hold the liquid medicine configured for infusion into a patient's body. Abroad, since the 1960s, PP or PE plastic bottles with good chemical stability, excellent airtightness and high temperature resistance have been used to dispense large infusions, which has better improved the packaging quality and shelf life of drugs. However, during the use of plastic bottle infusions, an air circuit still needs to be formed for the liquid medicine to drip out, and microparticles and bacteria in the air can still enter the liquid medicine through the air circuit, and the probability of secondary pollution is still relatively high, and the potential harm to human health still exists. To solve this problem, polyvinyl chloride (PVC) soft bag infusions came into being. During the use of soft bag infusions, the liquid medicine can be forced to drip out by relying on its own tension without forming an air circuit, greatly reducing the probability of secondary pollution.
[0003] For existing infusion bottles, their openings are generally sealed with rubber stoppers. When preparing the liquid medicine, an injection needle is inserted into the inside of the rubber stopper. However, for patients after radiotherapy of the head and neck, a specific mouthwash needs to be prepared to clean the inside of the mouth. Therefore, it is necessary to use physiological saline to prepare it for the patient to use. However, for existing physiological saline infusion bottles, it is not convenient to pour the liquid into the patient's mouth at the rubber stopper. Therefore, it is necessary to remove the rubber stopper, and the infusion bottle after removal is not convenient for storing the internal solution. Therefore, the inventor designs a conversion type bottle cap for an infusion bottle. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a conversion type bottle cap for an infusion bottle. The conversion type bottle cap is directly plugged onto the infusion bottle for use, which combines the functions of liquid medicine preparation and direct pouring, is convenient to use and has various functions.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A conversion type bottle cap for an infusion bottle, which includes a rubber stopper plugged onto the upper end of the infusion bottle. A rubber column is fixed in the middle of the rubber stopper. The outside of the rubber column is rotatably connected with a first cover plate and a second cover plate. Both the first cover plate and the second cover plate are arc-shaped. A stepped groove is arranged on one side of the rubber stopper, and a rubber plate is embedded in the stepped groove. The first cover plate covers the rubber plate. A trapezoidal opening is integrally arranged with the rubber stopper on the side opposite to the stepped groove, and the second cover plate covers the trapezoidal opening.
[0006] Furthermore, lifting strips are fixed on the upper surfaces of both the first cover plate and the second cover plate, and the first cover plate is located below the second cover plate.
[0007] Further, a first protrusion is fixed to the side of the first cover plate facing the stepped groove. There are two first protrusions symmetrically arranged. At the position corresponding to the first protrusion, a first concave hole is provided on the rubber stopper.
[0008] Further, a clamping groove with a shape corresponding to the trapezoidal opening is fixed to the side of the second cover plate facing the trapezoidal opening. The clamping groove is in interference fit with the trapezoidal opening. Second protrusions are provided on both sides of the clamping groove. At the position corresponding to the second protrusion, a second concave hole is provided on the rubber stopper.
[0009] The beneficial effects of the present utility model are as follows:
[0010] The structure is simple. It is improved on the existing rubber stopper structure by adding a stepped groove and a trapezoidal opening. A rubber plate is arranged inside the stepped groove, which can be used for the syringe to insert for medicine preparation. At the same time, the trapezoidal opening can be directly used for the patient to pour, which is convenient for use. 2. The first cover plate and the second cover plate are provided and respectively cover above the stepped groove and the trapezoidal opening to seal the stepped groove and the trapezoidal opening, preventing sundries from entering the inside of the infusion bottle and facilitating the storage of the internal solution.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] In order to further understand the content, features and effects of the present utility model, the following embodiments are cited and detailed as follows in conjunction with the drawings.
[0015] Please refer to Figures 1 to 2 simultaneously. The conversion type bottle cap for an infusion bottle according to the embodiments of the present utility model will be described in detail below in conjunction with the drawings.
[0016] As Figure 1 shown, it is assumed that the conversion type bottle cap for an infusion bottle includes a rubber stopper 1 inserted into the upper end of the infusion bottle. A rubber column 2 is fixed in the middle of the rubber stopper 1. A first cover plate 3 and a second cover plate 4 are rotatably connected to the outside of the rubber column 2. Both the first cover plate 3 and the second cover plate 4 are arc-shaped. A stepped groove 5 is provided on one side of the rubber stopper 1. A rubber plate 6 is embedded inside the stepped groove 5. The first cover plate 3 covers the rubber plate 6. A trapezoidal opening 7 is integrally provided with the rubber stopper 1 on the side opposite to the stepped groove 5. The second cover plate 4 covers the trapezoidal opening 7.
[0017] The rubber plate 6 inside the stepped groove 5 can be used for the insertion of a syringe during liquid preparation. The trapezoidal opening 7 provided is communicated with the inside of the infusion bottle, which can facilitate the patient to pour the liquid medicine inside the infusion bottle into the mouth.
[0018] Among them, lifting strips 8 are fixedly arranged on the upper surfaces of the first cover plate 3 and the second cover plate 4, and the first cover plate 3 is located below the second cover plate 4.
[0019] At the same time, a first protrusion 9 is fixedly arranged on the side of the first cover plate 3 facing the stepped groove 5. There are two first protrusions 9 arranged symmetrically. At the position corresponding to the first protrusion 9, a first concave hole 10 is provided on the rubber stopper 1.
[0020] A clamping groove corresponding to the shape of the trapezoidal opening 7 is fixedly arranged on the side of the second cover plate 4 facing the trapezoidal opening 7. The clamping groove and the trapezoidal opening 7 are in interference fit. Second protrusions 11 are arranged on both sides of the clamping groove. At the position corresponding to the second protrusions 11, second concave holes 12 are provided on the rubber stopper 1.
[0021] Furthermore, the first cover plate 3 or the second cover plate 4 can be rotated by pinching the lifting strip 8. In this embodiment, when it is necessary to prepare liquid medicine, the first cover plate 3 is rotated to open the stepped groove 5, and the syringe is inserted along the rubber plate 6 for liquid preparation. After the liquid preparation is completed, the first cover plate 3 is rotated back to its original position, and at the same time, the first cover plate 3 is pressed so that the first protrusion 9 thereon is clamped inside the first concave hole 10. When the patient uses it, the second cover plate 4 can be rotated, and the prepared mouthwash is poured into the mouth through the trapezoidal opening 7. At the same time, when not in use, the second cover plate 4 can be rotated back to its original position, and at the same time, the second cover plate 4 is pressed so that the second protrusion 11 thereon is clamped inside the second concave hole 12.
