Abstract
The invention discloses a single-base dual-pipe dual-membrane infusion bag. The single-base dual-pipe dual-membrane infusion bag comprises an infusion bag body and a single-base dual-pipe dual-membrane connector, wherein the single-base dual-pipe dual-membrane connector is formed inside the top of the infusion bag body, the single-base dual-pipe dual-membrane connector and the infusion bag body are welded into a whole, and a medicine adding opening and an infusion opening are formed in the single-base dual-pipe dual-membrane connector. The single-base dual-pipe dual-membrane infusion bag has the advantages of being easy to weld, low in liquid leakage rate, capable of being provided with the medicine adding opening and the infusion opening which are independent of each other, good in leakproofness due to the adoption of the membrane covering mode, low in contamination risk, and convenient to operate in clinical use. The single-base dual-pipe dual-membrane connector is a single-ship-shaped connector.
Description
Technical field
The present invention relates to a kind of transfusion bag, relate in particular to two-tube pair of diaphragm transfusion bag of a kind of single seat, common saying medical packaging material technical field.
Background technology
Existing pair of hard tube transfusion bag, by by two independently hard tube connector be welded on bag, after fill, need to weld two dual-valve covers its interface is sealed.
There is following shortcoming in this pair of hard tube transfusion bag:
1. use the cost of two valve gaps relatively high, and device structure complexity, station is on the high side;
2. because hard tube connector is open type, strengthened the risk of secondary pollution in process of production.
In addition, also have a kind of two hard tube transfusion bags, by by two independently hard tube connector be welded on bag, after fill, adopts two the independently hard tube with diaphragm and co-extrusion film Combination Welding, formation transfusion bag.
There is following shortcoming in this pair of hard tube transfusion bag:
1. this structure is the integral type hard tube of overlay film sealing, is difficult for welding, larger to the stretcher strain of co-extrusion film after welding, easily produces damaged leakage problem;
2. bag quality stability is not high, higher to equipment precision requirement.
Summary of the invention
The object of the invention is to: provide a kind of single seat two-tube pair of diaphragm transfusion bag, can meet under the prerequisite of Production requirement guarantee Product quality and safety, can raise the efficiency again, save production cost, reduce product leakage rate, reduce quality risk, improve the convenience of clinical use; Solve in existing transfusion bag production process and be easily secondary polluted, and transfusion bag quality is not good, the technical problem that leakage rate is high, thus can effectively solve above-mentioned problems of the prior art.
The object of the invention is to realize by following technical proposals: two-tube pair of diaphragm transfusion bag of a kind of single seat, comprise two-tube pair of diaphragm interface of bag body of infusion bag and single seat, two-tube pair of diaphragm interface of single seat is located at the inner side at the top of bag body of infusion bag, and two-tube pair of diaphragm interface of single seat and bag body of infusion bag are welded as a whole, on two-tube pair of diaphragm interface of single seat, dosing mouth and infusion port are set respectively.
As optimal way, two-tube pair of diaphragm interface of described single seat is single ship type interface.
As optimal way, described dosing mouth and infusion port are arranged side by side, and both centers of circle are all positioned on the line of symmetry of bag body of infusion bag top.
As optimal way, the co-extrusion film of two-tube pair of diaphragm interface of described single seat and bag body of infusion bag is welded as a whole.
In the present invention, the effect of part is as follows:
Bag body of infusion bag: play the effect of powder charge liquid and storage medicinal liquid.
Two-tube pair of diaphragm interface of single seat: two-tube pair of diaphragm interface of single seat carries dosing mouth and infusion port.
Dosing mouth: use for clinical compatibility.
Infusion port: in production for liquid medicine filling; Clinical in transfusion.
Compared with prior art, beneficial effect of the present invention: two-tube pair of diaphragm transfusion bag of single seat of the present invention possesses easy welding, leakage rate is low, and pollution risk is low, adopts film mulching method good leak tightness, has independent dosing mouth and infusion port, the advantage that clinical use is easy to operate.
Brief description of the drawings
Fig. 1 is the structural representation of two-tube pair of diaphragm transfusion bag of single seat of the present invention;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the side view of Fig. 1.
In figure: two-tube pair of diaphragm interface of 1-single seat, 2-bag body of infusion bag, 3-dosing mouth, 4-infusion port, 21-co-extrusion film.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further illustrated.
Disclosed all features in this description, or step in disclosed all methods or process, except the speciality and/or step of mutual repulsion, all can combine by any way, unless narration especially, all can be replaced by other equivalences or the alternative features with similar object,, unless narration especially, an embodiment in a series of equivalences of each feature or similar characteristics.
As Figure 1-3, two-tube pair of diaphragm transfusion bag of single seat of the present invention comprises bag body of infusion bag 2 and two-tube pair of diaphragm interface 1 of single seat, two-tube pair of diaphragm interface 1 of single seat is located at the inner side at the top of bag body of infusion bag 2, and two-tube pair of diaphragm interface of single seat 1 is welded as a whole with bag body of infusion bag 2, two-tube pair of diaphragm interface of described single seat 1 is single ship type interface, joint weld adopts comparatively ripe single ship type joint weld mode, reduces the high-precision requirement to equipment, reduces production costs simultaneously; Reduce the risk being secondary polluted in the quality of production, improve transfusion bag quality, reduce leakage.On two-tube pair of diaphragm interface 1 of single seat, dosing mouth 3 and infusion port 4 are set respectively; Described dosing mouth 3 and infusion port 4 are arranged side by side, and both centers of circle are all positioned on bag body of infusion bag 2 top line of symmetries.By the advantage that it easily welds, leakage rate is low, be combined with the mode that dosing mouth independently separates with infusion port, meet welding demand, realize the function that chemical feed pipe and tube for transfusion independently use.
Specifically, two-tube pair of diaphragm interface of described single seat 1 is welded as a whole with the co-extrusion film 21 of bag body of infusion bag 2, arrange conveyor hopper by production with interface interface is arranged to appropriate location, and direction is consistent, carry with polypropylene co-extrusion film and combine by equipment, then be made into transfusion bag by high-temperature soldering, its simple in equipment, mature production technology, easily realizes and producing.
The principle that realizes of the present invention:
Two-tube pair of diaphragm transfusion bag of single seat of the present invention combined by two-tube pair of diaphragm interface of single seat and bag body of infusion bag, main by equipment bag station making bag body of infusion bag, two-tube single seat pair of diaphragm interface sent into transfusion bag simultaneously, by heat seal welding, cooling and shaping, two-tube single seat pair of diaphragm interface and bag body of infusion bag are closely welded together again.Two-tube pair of diaphragm interface of its single seat and bag body of infusion bag welding procedure are simple, easily welding, leakage rate are low, little to film material welding stretching loss, overlay film good airproof performance, quality risk are low; When clinical use, dosing mouth and infusion port can independently separate use, easy to operate, go for the production of 50ml ~ 500ml product.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
