Anesthetic suction bottle capable of preventing needle stick injury and drug residue

Abstract

This invention discloses an anesthetic aspiration bottle designed to prevent needlestick injuries and medication residue. The bottle comprises a bottle structure, a needlestick-proof cap, and a medication residue-proof inner liner. The bottle structure includes a bottle body, a bottle head, and a rubber diaphragm, with an outer magnetic ring at the bottom of the bottle body. The needlestick-proof cap has a trumpet-shaped guide ring at the top, a clamp at the bottom, and an internal hollow cone structure. The medication residue-proof inner liner includes a top plate, a corrugated tube, and an inner magnetic ring. In use, the trumpet-shaped guide ring guides the needle tip into the hollow cone. The outer magnetic ring, through magnetic force, drives the inner magnetic ring, causing the corrugated tube to expand and contract, squeezing the medication from the inner liner into the hollow cone. The medication is then delivered to the syringe without residue through the inlet and inverted conical chamber. This design prevents needlestick injuries to medical personnel and avoids medication residue, improving the safety and efficiency of the anesthetic aspiration process.

Description

Technical Field

[0001] This invention relates to the field of anesthetic bottle technology, specifically to an anesthetic aspiration bottle that prevents needlestick injuries and drug residue. Background Technology

[0002] In the medical field, anesthetic aspiration is a common procedure in preoperative preparation. However, existing anesthetic aspiration devices have many problems, posing certain risks to medical staff and patient safety. Firstly, the risk of needlestick injuries is high. Traditional anesthetic vials lack an effective needle-guided design, making it easy for the needle to slip and prick the finger when medical staff insert it into the cap to draw the medication. This not only causes physical pain for medical staff but also carries the risk of contracting infectious diseases such as hepatitis B and HIV from contact with the patient's blood, seriously threatening the occupational health and safety of medical personnel.

[0003] On the other hand, the problem of drug residue is prominent. Existing anesthetic vials have a simple internal structure. During the extraction process, the angled needle tip cannot perfectly contact the inner wall of the vial, resulting in drug residue easily remaining on the inner wall and bottom of the vial, making complete extraction impossible. This not only wastes anesthetic and increases medical costs, but also, in some surgeries requiring precise dosage, the uncertain amount of residual drug may affect the anesthetic effect, thus impacting the success of the surgery and patient safety. Therefore, developing an anesthetic aspiration device that prevents needlestick injuries and avoids drug residue is of significant practical importance. Summary of the Invention

[0004] In view of the shortcomings mentioned above, this paper provides a technical solution for an anesthetic aspiration bottle that prevents needlestick injuries and drug residue.

[0005] The device includes a medicine bottle structure, with an inner liner to prevent medicine residue in the inner cavity of the medicine bottle structure. A bottle cap to prevent needle punctures is provided on the top of the medicine bottle structure. A clamp is fixedly connected to the bottom end face of the bottle cap to prevent needle punctures. A flared guide ring is fixed to the top end of the bottle cap to prevent needle punctures. A needle is provided above the flared guide ring. The bottom end of the needle is fixed with a needle tip that can be inserted into the bottle cap to prevent needle punctures.

[0006] The medicine bottle structure includes a bottle body, a bottle head fixedly connected to the top of the bottle body, and a rubber diaphragm fixed in the top port of the bottle head. A raised ring is fixedly connected to the outer surface of the bottle head, and an outer magnetic ring is fixed to the bottom of the outer ring of the bottle body.

[0007] The anti-needle puncture bottle cap includes a bottle cap, a hollow cone fixed to the top surface of the inner cavity of the bottle cap, and an inverted conical chamber opened at the bottom of the inner cavity of the hollow cone, with liquid inlets opened on the left and right side walls of the hollow cone.

[0008] The anti-residue liner includes a top plate, a corrugated pipe fixed to the bottom end face of the top plate, and an inner magnetic ring fixed to the bottom of the outer ring of the corrugated pipe. A liquid outlet is fixedly connected to the top of the top plate, and a silicone membrane is fixed in the top port of the liquid outlet.

[0009] In the above technical solution, preferably: the horn-shaped guide ring is in the shape of an inverted horn, and the diameter of the top port of the horn-shaped guide ring is larger than the diameter of the bottom port. The diameter of the internal cavity of the horn-shaped guide ring gradually decreases from top to bottom, which is used to guide the needle tip to pierce into the interior of the hollow cone.

[0010] In the above technical solution, preferably: the clamp is composed of 6-8 clamping blocks arranged in a ring array. When the anesthetic aspiration bottle is not opened, the clamp is clamped on the convex ring, and the bottom tip of the hollow cone is located above the rubber septum.

[0011] In the above technical solution, preferably: two sliding grooves are provided on the left and right sides of the outer ring surface of the bottle body for the outer magnetic ring to slide up and down, and the inside of each sliding groove is provided with a slider connected to the inner end face of the outer magnetic ring.

[0012] In the above technical solution, preferably, the bottle cap has an internal cavity that is adapted to and coupled with the shape of the outer surface of the bottle head.

[0013] In the above technical solution, preferably: a funnel-shaped groove communicating with the inner cavity of the hollow cone is provided at the top center of the bottle cap, and the inverted conical chamber, the liquid inlet and the inner cavity of the hollow cone are interconnected.

[0014] In the above technical solution, preferably: the inverted conical chamber is in the shape of an inverted pointed cone, and the shape of the inverted conical chamber is adapted and coupled to the tip of the needle and has a gap for the flow of anesthetic.

[0015] In the above technical solution, preferably, the outer ring surface of the top plate is fixedly connected to the top of the inner cavity side wall of the bottle body.

[0016] In the above technical solution, preferably, the inner diameter of the liquid outlet nozzle is the same as the outer diameter of the hollow cone.

[0017] In the above technical solution, preferably: the magnetism of the inner magnetic ring and the magnetism of the outer magnetic ring attract each other, and the outer surface of the corrugated tube is provided with corrugations for its vertical expansion and contraction.

[0018] As can be seen from the above technical solution, the anesthetic aspiration bottle provided by the present invention, which prevents needlestick injuries and drug residue, has the following beneficial effects compared with the prior art:

[0019] To prevent needlestick injuries, the top-mounted flared cap guides the needle tip downwards, preventing slippage and reducing the risk of needlestick injuries to medical personnel. For preventing drug residue, the bottle features an inner liner. Magnetic attraction between the outer and inner magnetic rings causes the outer ring to move, expanding and contracting the bellows to squeeze the medication into the hollow cone, ensuring no anesthetic residue is delivered to the syringe and minimizing waste. Furthermore, a clamp engages with a raised ring when unopened, ensuring a tight seal; the cap's internal cavity fits snugly against the bottle head's outer surface, enhancing connection stability; and the inverted conical chamber fits the needle tip with a gap, facilitating drug flow. This overall design improves the safety, convenience, and efficiency of anesthetic aspiration. Attached Figure Description

In order to provide a clearer explanation and description of the technical solutions and implementation methods of the present invention, the following describes specific embodiments that implement the preferred technical solutions of the present invention.

[0029] Example 1: The anesthetic aspiration bottle for preventing needlestick injuries and drug residue in this example includes a bottle structure 1. An outer magnetic ring 1-5 is fixed to the bottom of the outer ring of the bottle body 1-1. Two sliding grooves are provided on the left and right sides of the outer ring surface of the bottle body 1-1 for the outer magnetic ring 1-5 to slide up and down. There are sliders in the sliding grooves that are connected to the inner end face of the outer magnetic ring 1-5. A bottle head 1-2 is fixedly connected to the top of the bottle body 1-1. A rubber septum 1-3 is fixed in the top port of the bottle head 1-2. A raised ring 1-4 is fixedly connected to the outer ring surface of the bottle head 1-2. The medicine bottle structure 1 has an inner liner 6 for preventing medicine residue in its inner cavity. The outer surface of the top plate 6-1 of the inner liner 6 is fixedly connected to the top of the inner wall of the bottle body 1-1. A corrugated tube 6-4 is fixed to the bottom end face of the top plate 6-1. The outer surface of the corrugated tube 6-4 has corrugations that allow it to expand and contract. An inner magnetic ring 6-5 is fixed to the bottom of the outer ring of the corrugated tube 6-4. The magnetism of the inner magnetic ring 6-5 and the magnetism of the outer magnetic ring 1-5 attract each other. A dispensing nozzle 6-3 is fixedly connected to the top of the top plate 6-1. The inner diameter of the dispensing nozzle 6-3 is the same as the outer diameter of the hollow cone 2-5. A silicone membrane 6-2 is fixed in the top port of the dispensing nozzle 6-3. The bottle structure 1 is equipped with a needle-proof cap 2. The cap 2-1 of the needle-proof cap 2 has a cavity 2-2 inside that is adapted to and coupled with the outer surface of the bottle head 1-2. The bottom end face of the cap 2-1 is fixedly connected to a clamp 7. The clamp 7 consists of 6 clamping blocks arranged in a ring array. When the anesthetic aspiration bottle is not opened, the clamp 7 is locked on the convex ring 1-4.

[0030] A hollow cone 2-5 is fixed to the top surface of the inner cavity of the bottle cap 2-1. An inverted cone-shaped chamber 2-3 is opened at the bottom of the inner cavity of the hollow cone 2-5. The inverted cone-shaped chamber 2-3 is in the shape of an inverted pointed cone, and its shape is adapted to and coupled with the tip of the needle 3 and has a gap for the flow of anesthetic. Liquid inlets 2-4 are opened on the left and right side walls of the hollow cone 2-5. A funnel-shaped groove 2-6 is opened at the center of the top of the bottle cap 2-1, which communicates with the inner cavity of the hollow cone 2-5. The inverted cone-shaped chamber 2-3, the liquid inlet 2-4 and the inner cavity of the hollow cone 2-5 are interconnected. The top port of the anti-needle puncture bottle cap 2 is fixed with a flared guide ring 5. The flared guide ring 5 is in the shape of an inverted flared flare, with the diameter of the top port being larger than that of the bottom port. The diameter of the internal chamber gradually decreases from top to bottom. It is used to guide the needle tip 3 to pierce into the hollow cone 2-5. A needle 4 is set above the flared guide ring 5. The bottom end of the needle 4 is fixed with the needle tip 3 that is inserted into the hollow cone 2-5 inside the anti-needle puncture bottle cap 2. When the anesthetic aspiration bottle is not opened, the bottom tip of the hollow cone 2-5 is located above the rubber septum 1-3. In use, insert the syringe needle 4 along the trumpet-shaped guide ring 5, and the needle tip 3 enters the inverted conical chamber 2-3 of the hollow cone 2-5, allowing the hollow cone 2-5 to pierce the rubber septum 1-3 and the silicone membrane 6-2. Then, push the outer magnetic ring 1-5 to slide upward in the groove, and the inner magnetic ring 6-5 will move upward through the magnetic force, causing the bellows 6-4 to contract, squeezing the medicine in the anti-medication residue inner liner 6 into the hollow cone 2-5, and then entering the syringe through the gap between the liquid inlet 2-4 and the inverted conical chamber 2-3 to avoid medicine residue.

[0031] Example 2: The anesthetic aspiration bottle of this example, designed to prevent needlestick injuries and drug residue, has an outer magnetic ring 1-5 fixed to the bottom of the outer ring of the bottle body 1-1. The outer ring surface of the bottle body 1-1 is provided with a groove and a slider for the outer magnetic ring 1-5 to slide up and down. The top of the bottle body 1-1 is connected to a bottle head 1-2, which has a rubber diaphragm 1-3 on top and a raised ring 1-4 on its outer ring. The top plate 6-1 of the inner liner 6, designed to prevent drug residue, is connected to the top of the inner wall of the bottle body 1-1. The bottom of the top plate 6-1 has a corrugated tube 6-4, and the bottom of the corrugated tube 6-4 has an inner magnetic ring 6-5, which is magnetically attracted to the outer magnetic ring 1-5. The top of the top plate 6-1 has a dispensing nozzle 6-3, and the top of the dispensing nozzle 6-3 has a silicone membrane 6-2. The bottle cap 2-1 of the anti-needle puncture bottle cap component 2 has a cavity 2-2 inside that fits the bottle head 1-2. The bottom of the bottle cap 2-1 has a clamp 7, which consists of 7 clamping blocks and is locked on the convex ring 1-4 when not opened. The bottle cap 2-1 has a hollow cone 2-5 inside. The bottom of the hollow cone 2-5 has an inverted conical chamber 2-3 and liquid inlets 2-4 on both sides. The top of the bottle cap 2-1 has a funnel-shaped groove 2-6 that communicates with the inner cavity of the hollow cone 2-5. The top of the bottle cap 2-1 has a trumpet-shaped guide ring 5, and above it is a needle 4. The bottom of the needle 4 has a needle tip 3. When not opened, the tip of the bottom of the hollow cone 2-5 is above the rubber septum 1-3. During operation, the hollow cone 2-5 punctures the rubber septum 1-3 and the silicone membrane 6-2, and then pushes the outer magnetic ring 1-5 upward. The magnetic force causes the inner magnetic ring 6-5 to drive the bellows 6-4 to contract, squeezing the medicine in the anti-medication liquid residue inner liner 6 through the liquid outlet 6-3 into the hollow cone 2-5. The medicine then enters the syringe through the gap between the liquid inlet 2-4 and the inverted cone-shaped chamber 2-3, preventing medicine residue and needle slippage.

[0032] Example 3: The anesthetic aspiration bottle of this example, designed to prevent needlestick injuries and drug residue, has an outer magnetic ring 1-5 fixed to the bottom of the outer ring of the bottle body 1-1. The outer ring surface of the bottle body 1-1 has a groove and a slider for the outer magnetic ring 1-5 to slide up and down. The top of the bottle body 1-1 is connected to a bottle head 1-2, which has a rubber diaphragm 1-3 on top and a raised ring 1-4 on its outer ring. The top plate 6-1 of the inner liner 6, designed to prevent drug residue, is fixed to the top of the inner wall of the bottle body 1-1. The bottom of the top plate 6-1 has a corrugated tube 6-4, and the bottom of the corrugated tube 6-4 has an inner magnetic ring 6-5. The inner magnetic ring 6-5 is magnetically attracted to the outer magnetic ring 1-5. The top of the top plate 6-1 has a dispensing nozzle 6-3, and the top of the dispensing nozzle 6-3 has a silicone membrane 6-2. The bottle cap 2-1 of the anti-needle puncture bottle cap component 2 has a cavity 2-2 inside that fits the bottle head 1-2. The bottom of the bottle cap 2-1 has a clamp 7, which consists of 8 clamping blocks and is locked on the convex ring 1-4 when not opened. The bottle cap 2-1 has a hollow cone 2-5 inside. The bottom of the hollow cone 2-5 has an inverted conical chamber 2-3 and liquid inlets 2-4 on both sides. The top of the bottle cap 2-1 has a funnel-shaped groove 2-6 that communicates with the inner cavity of the hollow cone 2-5. The top of the bottle cap 2-1 has a trumpet-shaped guide ring 5, and above it is a needle 4. The bottom of the needle 4 has a needle tip 3. When not opened, the tip of the bottom of the hollow cone 2-5 is above the rubber septum 1-3. When in use, continuously press down on the anti-needle puncture bottle cap 2, and let the hollow cone 2-5 puncture the rubber septum 1-3 and the silicone membrane 6-2. Then push the outer magnetic ring 1-5 upward, and use the magnetic force to make the inner magnetic ring 6-5 drive the bellows 6-4 to contract, squeezing the medicine in the anti-medicine residue inner liner 6 through the dispensing nozzle 6-3 into the hollow cone 2-5, and then into the syringe through the gap between the inlet 2-4 and the inverted cone-shaped chamber 2-3, avoiding medicine residue and needle slippage injury.

[0033] Based on the above-described preferred technical solution, the working principle of the technical solution is explained as follows: In the unopened state, the anti-needle puncture bottle cap 2 is clamped onto the convex ring 1-4 of the bottle head 1-2 of the medicine bottle structure 1 by the clamp 7. At this time, the bottom tip of the hollow cone 2-5 is located above the rubber diaphragm 1-3. The cavity 2-2 inside the bottle cap 2-1, which is adapted to and coupled with the shape of the outer surface of the bottle head 1-2, is tightly connected to the bottle head 1-2. The outer ring surface of the top plate 6-1 is fixedly connected to the top of the inner cavity side wall of the bottle body 1-1. The inner magnetic ring 6-5 and the outer magnetic ring 1-5 are attracted to each other by magnetism. However, at this time, the outer magnetic ring 1-5 is at the bottom of the outer ring of the bottle body 1-1, and the inner magnetic ring 6-5 is at the bottom of the anti-medicine residue inner liner 6. The two are in a relatively far position, and the corrugated tube 6-4 is in a naturally extended state. When anesthetic is needed, the needle 4 is placed above the trumpet-shaped guide ring 5. Since the trumpet-shaped guide ring 5 is an inverted trumpet shape, its top port diameter is larger than its bottom port diameter, and the internal chamber diameter gradually decreases from top to bottom. This guides the needle tip 3 into the hollow cone 2-5. The hollow cone 2-5 continues downward, passing through the rubber septum 1-3 and entering the inner cavity of the vial structure 1. Next, the operator pushes the outer magnetic ring 1-5 at the bottom of the outer ring of the vial body 1-1 upwards. Two grooves are provided on the left and right sides of the outer ring surface of the vial body 1-1 for the outer magnetic ring 1-5 to slide up and down. Each groove has a slider connected to the inner end face of the outer magnetic ring 1-5, ensuring stable up-and-down sliding of the outer magnetic ring 1-5. The outer magnetic ring 1-5 attracts the inner magnetic ring 6-5 due to its magnetism, causing the inner magnetic ring 6-5 to move upwards. This causes the bellows 6-4 to contract, reducing the internal space of the inner liner 6 to prevent drug residue. The internal drug is then squeezed out from the outlet 6-3. The inner diameter of the dispensing nozzle 6-3 is the same as the outer diameter of the hollow cone 2-5, allowing the medication to enter smoothly. A funnel-shaped groove 2-6, located at the center of the top of the cap 2-1, communicates with the inner cavity of the hollow cone 2-5. The inverted conical chamber 2-3, the inlet 2-4, and the inner cavity of the hollow cone 2-5 are interconnected. The inverted conical chamber 2-3 is shaped like an inverted cone, its shape matching the tip of the needle 3 and leaving a gap for the anesthetic to flow through. The medication enters the inverted conical chamber 2-3 through the inlet 2-4, then flows through the gap into the needle tip 3, and finally is delivered into the syringe, achieving residue-free delivery of the anesthetic. After use, the needle 4 can be removed from the vial.
