Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specially a kind of infusion bottle preventing secondary pollution.
Background technology
At present, venous transfusion is the important method of hospital treatment patient, according to statistics, the needs of patients venous transfusion of 95% is had in inpatient, because venous transfusion is a kind of traumatic treatment, because many-sided reason causes untoward reaction to patient in infusion process, wherein venous transfusion pollutes and causes the complication such as infection and account for very large ratio, occur that the principal element of this reason has: one is because vial can not be flat flat, therefore need not cracked ends vent line in solution, introduce air in infusion process and produce pressure, and the dust in air, microorganism is (as antibacterial, fungus etc.) can enter in vial thus, cause the pollution of transfusion, two is the anthropic factors of violating sterile working's code, the author finds in basic unit's epidemic preventing working for many years and hygienic supervise work, grass-roots work condition and medical worker's level difference greatly, are usually met and are not worn masks, with hands direct mounting of syringe syringe needle etc. underproof operation.Even if County Hospital, some medical workers are after dosing, the bottle neck exposed is had nothing to fear in placement with during passing through ward corridor, some business personnels place a cotton ball soaked in alcohol to the bottle neck exposed, the author also often sees medicinal liquid and emerges after air chimney filter and extraneous contact and return in bottle, perhaps, this is indifferent thing at others, but the author worries really.
Application number 201010171455.1 discloses a kind of novel transfusion bottle, this invention comprises the bottle with internal cavities, described bottle is by upper bottle, lower bottle is formed, upper bottle, flexible partition is compressed with between lower bottle, flexible partition is by bottle, internal cavities is separated into drug storage chamber and air cavity, lower bottle place is provided with transfusion outlet, and upper bottle is provided with the passage connected with air cavity, passage place is provided with the seal head of this passage of sealing, although this invention solve flexible partition flat under atmospheric effect in air cavity under, namely drug storage intracavity can not enter air in use, stop air pollution, although feeding opening medicine outlet seals, but contact dosing mouth to be pulled out when dosing, insert transfusion device during transfusion and contact dosing mouth again, artificial hidden danger cannot be avoided, simultaneously seal head with passage with being threaded, operate inconvenience.
