Description

Technical Field

[0001] The present invention relates to the field of medical appliances, in particular to an automatic drug delivery and infusion device. Background Art

[0002] Infusion bottles are bottles for medical liquids that are infused into the human body during infusion. In foreign countries, PP or PE plastic bottles with good chemical stability, excellent air tightness, and high temperature resistance have been used to pack large infusions since the 1960s, which has greatly improved the packaging quality and shelf life of drugs. However, plastic bottle infusions still need to form an air circuit to allow the liquid to drip out during use. Particles and bacteria in the air can still enter the liquid through the air circuit. The probability of secondary pollution is still high, and potential harm to human health still exists. To solve this problem, polyvinyl chloride (PVC) soft bag infusion came into being. During use, the soft bag infusion can rely on its own tension to press the liquid to drip out without forming an air circuit, which greatly reduces the probability of secondary pollution. However, the plasticizer DEHP is added to the PVC material during the polymerization process to change its performance. Studies have shown that PVC soft bags may dissolve a trace of DEHP when used. DEHP is a harmful substance that seriously endangers human health. Secondly, the PVC soft bag is thick in texture, which is not conducive to processing. It has a high permeability to oxygen and water vapor, poor temperature adaptability, is easily deformed during high-temperature sterilization, and has poor tensile strength. These defects seriously limit its development in infusion packaging.

[0003] Under such circumstances, polyolefin multilayer co-extruded film non-PVC film came into being. Non-PVC multilayer co-extruded film was successfully developed internationally in the 1990s. The structure and strictly controlled production process of polyolefin multilayer co-extruded film determine that it not only has all the advantages of glass bottles, plastic bottles, and PVC films, but also has no toxic side effects on the human body, making it an ideal packaging material for infusion products.

[0004] The current infusion bottle has a single structure and function, is not convenient to use, and has many disadvantages. Therefore, it is imperative to design an automatic drug delivery infusion device. Summary of the invention

[0005] The technical problem to be solved by the present invention is that currently all medical staff need to first extract the medicine in the vial or ampoule bottle with an ordinary syringe when adding medicine to small-volume injections. When adding medicine to powder injections, they need to use an ordinary syringe to repeatedly puncture and extract a sufficient amount of injection solution and other solvents into the powder injection bottle, shake to dissolve, and then extract the dissolved solution into the infusion bottle. The above operation of repeated puncture and extraction of medicines may cause rubber particles to enter the infusion bottle, which is complicated and inefficient. Repeated contact of medicines with air can easily contaminate the medicine solution. In addition, hospital infection control cannot guarantee the safety of infusions. Moreover, it is easy to cut fingers when breaking open the ampoule, increasing the risk of occupational exposure. Even when busy, the wrong medicine may be added, increasing the risk of medical errors.

[0006] In order to solve the above technical problems, the technical solution provided by the present invention is: an automatic drug delivery and infusion device, comprising an upper mechanism, a movable hook is provided on the upper structure, a pressure balance port is provided on one side of the movable hook, a solvent liquid warehouse is provided under the upper structure, a drug channel is provided in the solvent liquid warehouse, an infusion device connection port is connected below the solvent liquid warehouse, the upper structure comprises an upper cover and a lower cover, a thread 1 is provided in the upper cover, a thread 2 matching the specification and size of the thread 1 is provided on the lower cover, the upper mechanism is connected to a delivery switch device through a connecting piece 1, a drug delivery port is provided in the delivery switch device, and an isolation device is provided below the drug delivery port; the main body of the drug channel is an inverted cone structure, the diameter specification of the upper end part of the drug channel is consistent with the diameter specification of the lower cover, and the diameter specification of the upper end part of the drug channel is consistent with the diameter specification of the isolation device.

[0007] Compared with the prior art, the advantages of the present invention are that the filling of the medicine is successfully performed in a sterile and closed environment from beginning to end, and there is no direct contact with the air, so the possibility of the medicine being contaminated during the filling process is effectively avoided. The device omits the operation process of medical staff frequently extracting medicines, saving a lot of labor intensity. In most clinical infusions that require the filling of medicines, the operation process of frequently extracting medicines is omitted, and the possibility of medical staff being contaminated during the operation is also eliminated, especially the syringe bottle needs to be repeatedly punctured to extract the medicine liquid, and rubber particles enter the infusion bottle, endangering the patient's infusion safety. In addition, the dispensing workflow is saved, and at the same time, the use of the dispensing infusion device is saved, reducing the patient's medical expenses and reducing the discharge of medical waste. In addition, when the workload is heavy, clinical medical staff often make mistakes in drug preparation, which increases the risk of infusion for patients and wastes drugs. This avoids drug contamination and error accidents in the above-mentioned ways, effectively avoids the possibility of drug liquid contamination in the drug preparation and dosing process, omits the dosing process, effectively liberates the labor of clinical drug dispensing workers, and allows them to devote more time and energy to serving patients, effectively saves the use of injectors, and reduces the generation of medical waste. It effectively avoids mistakes made by staff in a hurry and causes unnecessary errors and disputes in the clinic.

[0008] As an improvement, the movable hook comprises a hook body, one end of which is connected to a main shaft via a second connecting member.

[0009] As an improvement, the main body of the medicine delivery port is a through groove with circular holes at both ends.

[0010] As an improvement, the isolation device adopts an X-shaped rotating closing design, which rotates counterclockwise to open the drug delivery port and clockwise to close the drug delivery port.

[0011] As an improvement, the main body of the air pressure balance port is a cover port provided with a closable lid.

[0012] As an improvement, the isolating device rotates synchronously with the upper cover through a connecting piece 1. BRIEF DESCRIPTION OF THE DRAWINGS
