Description

An automatic drug delivery infusion device

technical field

The utility model relates to the field of medical appliances, in particular to an infusion device for automatic drug delivery.

Background technique

The infusion bottle is a bottle used for the medical configuration of the liquid in the human body in the patient's infusion. In foreign countries, PP or PE plastics with good chemical stability, excellent air tightness and high temperature resistance have been used since the 1960s. It can better improve the packaging quality and shelf life of the drug, but the plastic bottle infusion still needs to form an air circuit before dripping out, and the particles and bacteria in the air can still pass through the air. When the circuit enters the liquid medicine, the probability of secondary pollution is still high, and the potential harm to human health still exists. In order to solve this problem, PVC soft bag infusion came into being. The soft bag infusion can rely on its own tension to force the drug droplets out during use, without forming an air circuit, which greatly reduces the probability of secondary pollution. However, the plasticizer DEHP is added to the PVC material in order to change its properties during the polymerization process. Studies have shown that a small amount of DEHP may be dissolved in PVC soft bags during use. DEHP is a harmful substance that seriously harms human health. Secondly, the PVC soft bag is thick in texture, which is not conducive to processing. Its permeability to oxygen and water vapor is high, its temperature adaptability is poor, it is easily deformed by high temperature sterilization, and its tensile strength is poor. These defects seriously limit its use in infusion. Developments in packaging.

In this case, polyolefin multi-layer co-extruded film non-PVC film came into being. The non-PVC multi-layer co-extruded film was successfully developed in the 1990s. The structure of the polyolefin multi-layer co-extrusion film and the strictly controlled production process determine that it not only has glass bottles, plastic bottles, and PVC films. Advantages, and no toxic and side effects to the human body, is an ideal packaging material for infusion products.

The current infusion bottle has a single structure and function, is not convenient enough to use, and has many disadvantages. Therefore, it is imperative to design an infusion device for automatic drug delivery.

Utility model content

The technical problem to be solved by the utility model is that when all medical staff at present add medicines to small-volume injections, firstly, the medicines in the vials or ampoules must be extracted through a common syringe. It is necessary to repeatedly puncture with an ordinary syringe to 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. Repeated puncturing and extraction of medicines through the above operations can cause rubber particles to enter the infusion bottle, which is complicated and inefficient. It is easy to contaminate the liquid if the medicine is in contact with the air for many times. For hospital infection control, the safety of infusion cannot be guaranteed, and it is easy to cut fingers when opening ampoules, increasing the risk of occupational exposure, and even adding wrong medicines during busy hours, increasing the risk of medical errors.

In order to solve the above-mentioned technical problems, the technical scheme provided by the present utility model is as follows: an automatic drug injection infusion device, comprising an upper mechanism, a movable hook is arranged on the upper mechanism, a pressure balance port is arranged on one side of the movable hook, and a lower mechanism is provided with a movable hook. The solvent liquid chamber is provided with a drug channel, and the lower part of the solvent liquid chamber is connected with an infusion set connection port. Thread 2 with matching size, and the upper mechanism is connected with a release switch device through connecting piece 1.

Compared with the prior art, the utility model has the advantages that: the whole process of filling the medicines is completed successfully in a sterile and airtight environment without direct contact with the air, so the medicines are effectively prevented from being polluted during the filling process. possible. The device omits the operation process of frequently extracting medicines by medical staff, which saves a lot of labor intensity. In most clinical infusions that need to be filled with medicines, the operation process of frequently extracting medicines is omitted, and the occurrence of operation processes by medical staff is also eliminated. In particular, the vial needs to be repeatedly punctured to extract the liquid, and rubber particles enter the infusion bottle, which endangers the patient's infusion safety, and saves the dispensing workflow and the use of dispensing infusion sets. , reduce the medical expenses of patients and reduce the discharge of medical waste. In addition, when the workload is large, the clinical medical staff often have the wrong medicine, which increases the risk of patient infusion, and wastes medicine, which avoids the above-mentioned various ways of medicine contamination and error accidents. , effectively avoiding the possibility of drug liquid pollution in the process of dispensing and dosing, omitting the dosing process, effectively liberating the labor force of clinical dispensing workers, and being able to devote more time and energy to patient service work, It effectively saves the use of the injector and reduces the generation of medical waste. Effectively avoid staff mistakes while busy, causing unnecessary errors and disputes in clinical practice.

As an improvement, the movable hook includes a hook main body, and one end of the hook main body is connected with the main shaft through the second connecting piece.
