Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel disposable closed-loop infusion pipeline. Background Art

[0002] Medicine is a discipline that deals with issues related to the well-being of the human body, as defined by health. Its goal is to treat and prevent physical illness and improve the health of the human body. In a narrow sense, medicine encompasses the treatment of disease and the restoration of effective bodily functions. Broadly speaking, medicine also encompasses Chinese health preservation and its Western derivative, nutrition. The scientific nature of medicine lies in the continuous refinement and practical validation of basic medical theories, such as biochemistry, physiology, microbiology, anatomy, pathology, pharmacology, statistics, epidemiology, as well as Traditional Chinese Medicine (TCM) and its techniques, to treat disease and promote health. Medicine can be divided into various medical systems, including modern medicine and traditional Chinese medicine. Major research areas include basic medicine, clinical medicine, forensic medicine, laboratory medicine, preventive medicine, health care medicine, and rehabilitation medicine. Basic medicine includes: medical biomathematics, medical biochemistry, medical biophysics, human anatomy, medical cell biology, human physiology, human histology, human embryology, medical genetics, human immunology, medical parasitology, medical microbiology, medical virology, human pathology, pathophysiology, pharmacology, medical laboratory animal science, medical psychology, biomedical engineering, medical informatics, first aid, nursing, and the new central dogma.

[0003] Dispensing refers to the use of computer systems in hospitals and pharmacies to dispense and distribute medicines. It involves adding a certain ingredient, applying a certain medicine, or treating with a certain medicine to one or several known quantities of medicines. The process of dispensing medicines involves the use of disposable closed-loop infusion pipelines.

[0004] When it comes to medical dispensing, the use of disposable infusion closed-loop pipelines is involved. However, a common dispensing operation cycle on the market currently includes three syringe insertion and removal actions and two suction and injection of liquid medicine. On the other hand, a certain negative pressure is maintained in the infusion container, and the infusion solution cannot flow directly into the powder container. At the same time, the suspension in the powder container cannot flow directly into the infusion container. The same problem also exists in the aqueous dispensing device, thereby reducing the efficiency of dispensing. The multiple insertion and removal of the syringe also increases the risk of needle sticks for the user, which also brings inconvenience to the user. Moreover, the multiple insertion and removal of the disposable syringe can easily bring out particles of the liquid medicine, causing environmental pollution. Utility Model Content

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the utility model provides a new type of disposable infusion closed-loop pipeline, which solves the problem of air pressure in the powder container during medication dispensing and the problem of solutions in the powder container and infusion container flowing into each other, and also solves the problem of multiple insertions and removals of the syringe during medication dispensing.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] The present invention provides a new type of disposable closed-loop infusion pipeline. Figure 1 、 Figure 2As shown, it includes a handle shell 1, which has anti-slip grooves to facilitate user holding. A replacement needle 7 is connected to the top of the handle shell 1. The setting of the replacement needle 7 achieves the effect of being connected to the powder container. The surface of the replacement needle 7 is covered with a protective sleeve 9. The coordinated setting of the replacement needle 7 and the protective sleeve 9 achieves the effect of conveniently protecting the replacement needle 7. The bottom of the handle shell 1 is connected to the top of the Y-shaped shell 2. The bottom of the Y-shaped shell 2 is divided into a syringe end 3 and a hose end 4. The coordinated setting of the syringe end 3 and the hose end 4 achieves the effect of separately connecting the infusion container and the syringe. The syringe end 3 is connected to the syringe. The setting of the syringe end 3 achieves the effect of being connected to the syringe. The hose end 4 is connected to the hose 5. The hose 5 is connected to the needle tube connector 6 away from the Y-shaped shell end. The needle tube connector 6 is connected to the replacement needle 8. The setting of the replacement needle 8 achieves the effect of being connected to the infusion container. The surface of the replacement needle 8 is covered with a protective sleeve 10.

[0024] Displacement needle 1 (7) is connected to the Y-shaped housing syringe end (3) via a conduit (11). This conduit (11) reduces or increases the air pressure within the powder container. Displacement needle 1 (7) is connected to displacement needle 2 (8) at the hose end of the Y-shaped housing via a conduit (2). This conduit (2) allows for fluid flow between the powder container and the infusion container. The combination of conduits (11) and (12) allows the entire dispensing cycle to be completed with a single push and pull of the syringe.

[0025] Working Principle: Step 1: Remove protective cover 1 (9), insert disposable closed-loop infusion line replacement needle 1 (7) into the powder container stopper, remove protective cover 2 (10), insert disposable closed-loop infusion line replacement needle 2 (8) into the infusion container stopper, insert the needle of the disposable needle-free syringe into the syringe end (3), and pull out the syringe. The air pressure in the syringe decreases because the syringe and powder container are connected via pipe 1 (11). The air pressure in the powder container is reduced through pipe 1 (11), forming a negative pressure in the powder container. The powder container and infusion container are connected via pipe 2 (12). When negative pressure is formed in the powder container, the solution in the infusion container flows into the powder container via pipe 2 (12).

[0026] Step 2: The solution entering the powder container dissolves with the powder in the powder container to form a mixed liquid;

[0027] Step 3: Push the syringe again to press the gas in the syringe back into the powder container through pipe 11. The air pressure in the powder container increases. Since the powder container and the infusion container are connected through pipe 2 12, the mixed liquid in the powder container is pressed into the infusion container through pipe 2 12, completing one dispensing cycle.

[0028] In summary, the novel disposable infusion closed-loop pipeline achieves the effect of controlling the air pressure in the powder container through the syringe by configuring the syringe end 3, the handle housing 1, the replacement needle 7, and the pipeline 11, and achieves the effect of mutual circulation between the solutions in the powder container and the infusion container by configuring the replacement needle 8, the needle-tube connector 6, the hose 5, the hose end 4, the handle housing 1, and the replacement needle 7.

[0029] By coordinating the pipe 11 and the pipe 2 12, the entire dispensing cycle can be completed by pulling out and injecting the syringe once, which is convenient for users, improves the working efficiency of the syringe, reduces the volatilization of liquid medicine particles, and reduces the risk of environmental pollution.
