Description
Technical field
This utility model relates to a kind of defecator and includes its filtration infusion vessel.
Background technology
Clinical transfusion is an important clinical subject of modern medicine.It includes the important content such as water and the Balance disorders of electrolyte, acid base imbalance and threpsology, and these Balance disorders occur together in multiple pathological process.While nursing one's health these Balance disorders, the different state of an illness corresponding medicine of direct intravenous injection is can also be for, to reach rapidly and efficiently to alleviate and treat the purpose of disease by reasonably transfusion.
Along with the needs of medical treatment and improving constantly of pharmaceutical technology, therapeutic transfusion kind enters clinic the most successively.Therefore, infusing by the attention of clinicians at different levels and be employed, the consumption of infusion preparation the most quickly increases, current China year consumption per capita reached more than 3 bottles.In order to adapt to the demand of medical treatment, infusion solutions manufacturing industry increase while yield for improve product quality and safe medication, the lifting of preparation packaging level and by the great attention in pharmacy industry.And the hard plastic bottle emerged in the recent period and non-PVC-soft plastic bag packaging large infusion production line, bringing one new trend to infusion solutions commercial production, clinical practice is the most safe and reliable.But also occur in that some new problems simultaneously.Packed in flexible pouchy technology is reviewed for discussion by transfusion package state of development emphasis.
Owing to medicinal liquid is directly entered blood, moment (< 1 minute) just can be distributed whole body, venous transfusion clinical treatment at home is highly important base therapy means.The data that drug-induced disease Professional Committee of Chinese Pharmacological Society provides show: the domestic inpatient more than 70% has carried out infusion.
" existing infusion mode mostly is carrier transfusion, and carrier transfusion person is more than 90% clinically；Carrier transfusion causes thermal source and particulate matter superposition, easily increases infusion safety risk." particulate matter exceeds standard and endotoxin increase is one of the main cause that transfusion occurs untoward reaction.The multiple disease harm that particulate matter entrance human capillary vessel blocks initiation is huge.
Particulate matter all may be had to be mixed into from producing clinical links, such as pharmaceutical production links control is strict, packaging material, operation link, supporting apparatus, environment are brought into.
" Chinese Pharmacopoeia " right >=and the particulate matter of 10 μm and >=25 μm defines, but not yet relates to the microgranule of 2～10 μm.And once the particulate matter of 2～10 μm enters human body, the time of discharge is even more than 20 years.
At present, a lot of children's hospitals and Grade A hospital at home, a kind of precision transfusion filter extremely sells well, and the major function of this product is to filter out in transfusion the impurity such as particulate matters more than 2 μm and visible foreign matters, but this kind of product is higher in price, brings burden to patient.And existing filter for transfusion is arranged on tube for transfusion so that the structure on tube for transfusion is complicated, it is unfavorable for producing.
Therefore infusion products particulate matter control standard should just be improved manufacturing link, a Novel filter device is studied for this our company, this device can be matched on the infusion vessel such as infusion solutions bottle, soft bag bottle, it is possible to is directly connected on transfusion bottle/bag interface manufacturing link.
Utility model content
