Abstract
The utility model relates to an air filtration venous infusion device, belonging to the field of medical appliances, which is composed of an infusion bottle (bag), an infusion pipe, a Mophy type burette, a needle head and an air inlet pipe. The utility model is characterized in that a filter is arranged in the air inlet pipe of the infusion device to achieve the aim of filtering and decontaminating the air entering the infusion bottle (bag); the contamination of infusion is prevented, and the infusion reaction of patients is reduced. The air filter of the utility model is respectively made of mixed cellulose ether microporous filtering films, sponges, plastics, resin, cottons and porous ceramic materials, and the clinical use is convenient.
Description
This utility model belongs to medical instruments field
On modern age clinical treatment history, venous transfusion (blood transfusion) is to be used for the treatment of, to rescue one of effective treatment means than the critical patient always, in application process, be the cross infection that wards off disease, intravenous transfusion device is by venous transfusion (blood transfusion) device of the sterilization repeatedly used muptiple-use application in back, progressively use instead and be disposable venous transfusion (blood transfusion) device, but the air inlet pipe of transfusion device does not but have any improvement so far.Usually, through the air inlet pipe of transfusion device enter air in the infusion bottle (bag) be in the environment without the air of any processing, so the cleaning of air will inevitably have influence on bottle (bag) interior liquid, and then have influence on the patient effect.Especially be subjected under the situation of pollutions such as extraneous dust, flue dust, pollen and other pyrogeies at air, as in the open air, reach transfusion (blood) under the specific conditions such as battlefield during the journey, very easily cause patient's infusion reaction, to patient cause unnecessary transfusion contaminated and harm patient.
Goal of the invention of the present utility model provides a kind of venous transfusion (blood transfusion) device that has air filter (device), enters the interior air of transfusion (blood transfusion) bottle (bag) with filtration, purification, prevents that transfusion (blood transfusion) is contaminated.
Goal of the invention of the present utility model reaches by the following technical programs: defecator (device) is installed in the air inlet pipe of disposable and muptiple-use use venous transfusion (blood transfusion) device.Filtering material adopts composite fibre ester microporous filter membrane, various different materials such as sponge, plastics, resin, Cotton Gossypii respectively.Defecator (device) can be made into different-thickness according to medical worker's needs, and is installed in the interior any part of air inlet pipe of the intravenous transfusion device of disposable and muptiple-use use.
This utility model air filtration venous transfusion (blood transfusion) device has following advantage compared with prior art:
Owing in the air inlet pipe of venous transfusion (blood transfusion) device defecator (device) has been installed, make the air that enters in the infusion bottle (transfusion bags) through filtration, purification, make airborne pathogenic bacteria, dust, pollen and other pyrogeies etc. can not enter transfusion (blood transfusion) bottle (bag), make transfusion (blood transfusion) reach cleaning sterile, it is contaminated and endanger patient in transfusion (blood transfusion) afterreaction and transfusion (blood transfusion) to reduce patient.
This utility model embodiment: through test, emergency case observation ward in certain hospital, get 6 bottles of normal saline, respectively join the disposable use intravenous transfusion device of a cover, be divided into two groups, one group air filter (device) is installed in air inlet pipe, another group compares, and the simulation titration is when treating that normal saline remains 10 milliliters of left and right sides in the infusion bottle, stop titration, respectively get 1 milliliter of residue normal saline with aseptic method then, with plain agar and blood plate culture medium antibacterial culturing, the result is that to add one group of antibacterial culturing of air filter all negative, matched group does not promptly add a group of air filter, and wherein one bottle normal saline finds to have bacterial growth through cultivating.Prompting directly enters infusion bottle without the air that purifies and has the danger of polluting transfusion liquid.
Do not examine the data of this respect through literature searches in March, 92 in 84 years to.
