Description
Technical field
This utility model relates to transfusion bag, particularly a kind of vertical polypropylene transfusion bag with Rotatable hanging hook.
Background technology
Infusion is the Therapeutic Method directly being inputted various sterile solution or medicine by vein, because its onset is rapid, determined curative effect, and becomes one of Therapeutic Method basic and the most the most frequently used in modern clinical treatment.
Infusion is developed so far existing nearly 180 years history:
British William in 1628 breathes out the blood circulation theory tieing up proposition and has established the basis of infusion;
Within 1831, Scotland doctor injects venous patient in order to treat cholera with the saline solution boiled, and becomes infusion and is applied to the first of human body;
1931 after 100 years, produced in USA go out first bottle of business infusion products, indicate the venous transfusion product introduction stage of industrialization development;
To nineteen sixty, the kind of whole world venous transfusion product has reached 200 kinds, and the development of infusion apparatus simultaneously has also promoted updating of venous transfusion administering mode.
Because venous transfusion is the Therapeutic Method directly entering blood circulation of human body, therefore how to guarantee that infusion safety is the key subjects concerning patient vitals's safety.
Make a general survey of the clinical practice of infusion products, venous transfusion mode goes through three changes: from full open model to semi open model, then to total closed type.
First time is changed: full open model transfusion is after infusion products is opened, being poured into by liquid is connected with in the wide mouth glass bottle of transfusion catheter, reinject the infusion model of human vein, because liquid is exposed in air very easily contaminated completely, in addition transfusion wide mouth glass bottle and transfusion catheter are the rear Reusability of sterilization, thus safety is very poor, is eliminated completely at present.
Second Revolution: half-open infusion model uses a transfusion device with airway to connect infusion products and human vein, be mainly used in the infusion products with vial and the PP plastic bottle rigidity that is representative and semi-rigid material packaging, constantly must import the normal infusion of air guarantee liquid during use in liquid, it is current domestic Clinical practice infusion model the most widely.
At present according to examining report, containing hundreds thousand of of diameter > 0.5 μm of microgranule in the every litres of air of hospital, about bacterial population 50,000/ware.The clean situation at most domestic hospital transfusion therapeutic room scene is generally poor, infuses in the environment that artificial abortion mixes, and very easily causes air to the secondary pollution of medicinal liquid; Even if lesion clean environment is slightly good, also cannot stops the secondary pollution of air to medicinal liquid, thus potential hazard is caused to the infusion safety of patient.
Import air to the pollution of medicinal liquid to reduce, the airway end of disposable transfusion device is provided with air filter film usually now.But research shows: have filter membrane and do not have filter membrane there is no significant difference in liquid contamination rate, do not solve the root problem of infusion safety from source.
Therefore, still there is larger potential safety hazard in half-open infusion model, substantially superseded in developed countries such as America and Europes, believes in the near future, and this infusion model also will inevitably progressively be abandoned by China.
Third time is changed: the maximum advantage of closed infusion model is without the need to importing air from the external world in infusion process, utilize atmospheric pressure to overcome human vein pressure completely, enter in blood circulation of human body process at medicinal liquid, infusion products, infusion apparatus, human vein form a complete total closed type system, thus arrive the effect of safe infusion.This is also the safe infusion mode that " venous transfusion special commission of the Nurses Association of China " advocates.
Total enclosing infusion model relies on outside atmospheric pressure to exert pressure to infusion vessel, extruding of infusing in container is entered blood circulation of human body system, therefore, infusion vessel can only use flexibility plastic as PVC(polrvinyl chloride) and the transfusion bag made such as non-PVC multi-layer co-extruded film, but showing through clinical practice for many years and other research, there is following problem in PVC and non-PVC multi-layer co-extruded film transfusion bag:
First be the safety issue of transfusion package material itself;
Secondly, the work efficiency problem of clinical nursing procedure;
3rd, environmental issue.PVC material is the plastic of bio-refractory, and can produce carcinogen bioxin after burning, and cause severe contamination to environment, the harmless treatment of discarded transfusion bag has become a difficult problem urgently to be resolved hurrily.
Therefore, market is infused in the urgent need to meeting the closed infusion model product of China's actual conditions.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provide a kind of hang and hang convenient, can uprightly place and the airtight vertical polypropylene transfusion bag with Rotatable hanging hook from discharge opeing.
The purpose of this utility model is achieved through the following technical solutions: a kind of vertical polypropylene transfusion bag with Rotatable hanging hook, it comprises bag mouth from top to bottom successively, bag neck, at the bottom of bag and bag, cave in cavity direction in bag in the middle part of at the bottom of described bag and form an annular groove with bag, described bag base thickness degree is greater than a bag neck depth degree, bag neck depth degree is greater than bag thickness, in the middle of the bag that front view is described in the radial direction, two ends are progressively thinning to the left and right, in the middle of bag described on front view axial direction, two ends are progressively thickening up and down, described bag bottom surface center is provided with a boss, a screwed hole is offered in boss, a plastic screw is connected with in screwed hole, the head of described plastic screw offers a cannelure, suspension ring are slidably connected with in cannelure, suspension ring are connected with a hook.
Described plastic screw head place horizontal line is higher than place, bottom surface horizontal line at the bottom of bag.
This utility model has the following advantages: transfusion bag of the present utility model, and bag base thickness degree is greater than a bag neck depth degree, and bag neck depth degree is greater than bag thickness, and transfusion bag can uprightly be placed, and facilitates Clinical practice; Bag intermediate thin, surrounding are thick, transfusion bag can be realized under atmospheric pressure airtight from draining function; The bag end, is provided with Rotatable hanging hook, and it is convenient to hang.
