Description

Electronic control shading device for infusion

The present invention belongs to the field of medical appliances, and more particularly to a light shielding device, and more particularly to a light shielding device for infusion.

There are many intravenous drugs that are easily degraded by light, for example, sodium nitroprusside, pyridine drugs (such as nifedipine, nitrendipine, cilnidipine, nimodipine and cilnidipine), water-soluble vitamins ( For example, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin C and folic acid), thiazides (such as promethazine hydrochloride and chlorpromazine hydrochloride), quinolones antibiotics (such as moxifloxacin, sparfloxacin) , ciprofloxacin, ofloxacin, levofloxacin, lomefloxacin, enoxacin, fleroxacin and gemifloxacin), phenolic drugs (eg phenethylamine, adrenaline, isoproterenol, Norepinephrine, dopamine and morphine), arylamine drugs (such as sodium p-aminosalicylate), hormonal drugs (such as estradiol benzoate), drugs containing unsaturated carbon bonds (such as amphotericin B), parts Chemotherapeutic drugs (eg cisplatin, carboplatin, oxaliplatin, cyclophosphamide, cytarabine, nimustine, thiotepa, methotrexate, and fluorouracil), etc., these drugs are administered intravenously Time, Infusion to use. Therefore, how to keep the drugs in the dark state is a very important problem in the process of using the infusion set for intravenous injection. Many publications today provide different methods of protecting against light to address the aforementioned problem of avoiding light to minimize the extent to which the drug is decomposed by illumination.

However, current practices or existing methods of avoiding light in the published literature still have different limitations. For example, in practice, an infusion set containing a light-shielding agent is often used to protect the infusion from light. A light-shieling agent is added to the material of the infusion device to reduce the degree of decomposition of the drug due to illumination, or a hood is used to shield the infusion solution. Device. For the infusion set containing the light-shielding agent, the light-protecting agent used in the early light-proof infusion set is directly in contact with the liquid medicine, and the light-proofing agent will enter the human body with the liquid medicine during the infusion process, which is harmful to health; The device has been improved with the evolution of the times. Compared with the general infusion set, the whole black light insufflator has higher manufacturing cost, the manufacturing process is more complicated, and it is disposable, which is easy to cause light-proof agent pollution.

As for the cover of the infusion set with the hood, the cover design of the existing hood still has problems such as unfavorable observation of the infusion, confidentiality of the patient medication information, and inconvenient use. Taking the unfavorable observation of the infusion case as an example, since the cover body only leaves a small window for observing the infusion condition, the infusion condition cannot be known outside the window observable range, which is not conducive to comprehensively grasping the dosage of the medicine; The total amount of the drug can only be taken out of the cover, which leads to exposure of the drug and also reveals information on the patient's medication. As for the ease of use, some covers are made of Velcro or pull-down zippers, and it is inconvenient for medical personnel to replace the vials with one-hand operation; the cover design does not take into account the factors that require different patient sizes and different vials. The result is poor versatility; other problems such as insufficient length of the cover after the suspension is caused by the exposure of the medicine, or the length of the cover after the cover is too long, which affects the space of the ward and the patient experience. In view of this, there is a need for a new hood to assist in the prevention of light infusion, and to provide better experience and effects for both patients.

The novel content is intended to provide a simplified summary of the disclosure in order to provide a basic understanding of the disclosure. This Summary is not an extensive overview of the disclosure, and is not intended to identify key/critical elements of the novel embodiments or the scope of the invention.
