Abstract
The utility model relates to the technical field of medical equipment an interior prevent disposable drainage bag against current, including the stock solution bag body, the hot pressing of stock solution bag body four sides is sealed, the last side pressure equipment associated drainage catheter of the stock solution bag body, and the lower side pressure equipment of the stock solution bag body has a leakage fluid dram, and it is internal and be connected with the blade against the current of preventing of two surface laminatings that inlet that the feed liquor was taken over stretches into the stock solution bag, prevents against the current blade side press seal about, inlet intercommunication that upside and feed liquor were taken over, the inner chamber intercommunication of downside and the stock solution bag body has the liquid flow to prevent fashionably that the subsides of adverse current blade are kneaded dough when the inlet and is washed open the feed liquor by the liquid stream. The utility model discloses a drainage bag sets up the blade against the current of preventing of one -way feed liquor in inlet department, and two binding faces of blade are washed open the realization feed liquor under only the inlet has a circumstances of liquid stream to this blade, and flow channel is closed in the laminating of two blades when the aneroid flows the pressure differential, and the binding face of blade can't be opened to the liquid in the bag, has consequently avoided the adverse current of the interior liquid of bag.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly to the single use drainage bag of a kind of counterflow-preventing.
Background technology
Drainage bag is at the postoperative drainage of the patient with operation that medically can be not only used for such as thoracic cavity and abdominal cavity, it is also possible in long-term bed and the drain being difficult to patient or even the family special care person etc. that take care of oneself.Namely splanchnocoel postoperative patient is used and then shows as drainage bag worthy of the name by the former, and namely long-term bedridden patients or even home care patients are used mainly for bladder urethral catheterization by the latter, is therefore called urinary bag in medically custom.
The easy disposable drainage bag of the existing one of our company, its agent structure is by a piece of polyethylene soft plastic sheet doubling back edge hot sealing, and the direct high frequency heat seal drainage catheter of upper edge press seal, lower edge dress leakage fluid dram, leakage fluid dram blocks up by sealing cap seal, covers after taking lower sealing cover discharge opeing during discharge opeing again.The drainage bag of this structure, in use, when the liquid-liquid in liquid storing bag is full of soon, liquid is susceptible to flow backwards, and affects the health of user.It addition, leakage fluid dram by seal cap seal block up, during discharge opeing operation inconvenience, it is easy to be discharged to operator on hand or seal lid drop.
Utility model content
The deficiency that this utility model exists for drainage bag structure of the prior art, provides the single use drainage bag of a kind of counterflow-preventing.
The purpose of this utility model is realized in, a kind of single use drainage bag of counterflow-preventing, liquid storage bag including pvc material, described liquid storage bag four limit high frequency heat seal seals, the upside of liquid storage bag is equipped with hanger, the upside of liquid storage bag is connected to drainage catheter, the lower side of described liquid storage bag is equipped with leakage fluid dram, it is characterized in that, the inlet of described liquid storage bag stretches in liquid storing bag body and is connected to the counterflow-preventing blade of two panels surface laminating, the left and right side high frequency heat seal of described counterflow-preventing blade, upside connects with the inlet of feed liquor adapter, the inner space of downside and liquid storage bag, when inlet has liquid to flow into, the patch dough-making powder of counterflow-preventing blade is washed open feed liquor by liquid stream.
Drainage bag of the present utility model, the counterflow-preventing blade of unidirectional feed liquor is set at inlet place, can effectively prevent the liquid in bag from flowing backwards, when this blade only has inlet to have liquid stream, two binding faces of blade are washed open and realizes feed liquor, when without flow stream pressure difference, fluid course is closed in two blade laminatings, and the liquid in bag cannot open the binding face of blade, therefore avoids the adverse current of liquid in bag.
Assembling for ease of drainage catheter, described liquid storage bag upper side edge connects drainage catheter place and takes over equipped with feed liquor, described drainage catheter plug-in mounting enter feed liquor adapter in connect with liquid storing bag intracoelomic cavity, the other end of described drainage catheter is connected to taper joint, and described taper joint is encapsulated by conical lid.In this structure, drainage catheter is connected by feed liquor adapter with liquid storage bag junction, drainage catheter is connected with feed liquor adapter plug-in mounting, realize the connection of drainage catheter and liquid storage bag, namely can ensure that effective, connect reliably, it is also possible to prevent the pipe passage of junction from making feed pathway be obstructed through high frequency heat seal deformation.
For ease of the discharge of liquid in bag, the leakage fluid dram connected drainage adapter of described liquid storage bag lower side, the described drain connection port of export is connected to tapping valve.
For ease of the emptying of liquid in bag, described liquid storage bag includes anter and the rear panel of four limit high frequency heat seals, and described anter or rear sheet surface are provided with the scale graticule representing liquid storage bag liquid capacity；High frequency heat seal envelope line on the downside of described liquid storage bag is the arc that upwarps of two ends or fold-line-shaped, and the inlet of described drain connection is arranged on the minimum point place of the high frequency heat seal envelope line of downside.
Accompanying drawing explanation
Fig. 1 is the structural representation of the single use drainage bag of counterflow-preventing of the present utility model.
Wherein, 1 liquid storage bag；2 counterflow-preventing blades；3 feed liquor adapters；4 drainage catheters；5 hangers；6 taper joints；7 drain connections；8 tapping valves.
Detailed description of the invention
It is illustrated in figure 1 the single use drainage bag of counterflow-preventing of the present utility model, liquid storage bag 1 including pvc material, liquid storage bag 1 four limit high frequency heat seal seals, the upside of liquid storage bag 1 is equipped with hanger 5, the upside of liquid storage bag 1 connects drainage catheter 4, and the downside of liquid storage bag 1 is connected to leakage fluid dram 7；The inlet of liquid storage bag 1 stretches in liquid storage bag 1 and is connected to the counterflow-preventing blade 2 of two panels surface laminating, the left and right side high frequency heat seal of counterflow-preventing blade 2, upside connects with the inlet of feed liquor adapter 3, the inner space of downside and liquid storage bag 1, when inlet has liquid to flow into, the patch dough-making powder of counterflow-preventing blade 2 is washed open feed liquor by liquid stream.Drainage bag of the present utility model, the counterflow-preventing blade 2 of unidirectional feed liquor is set at inlet place, can effectively prevent the liquid in bag from flowing backwards, when this blade only has inlet to have liquid stream, two binding faces of blade are washed open and realizes feed liquor, when without flow stream pressure difference, fluid course is closed in two blade laminatings, and the liquid in bag cannot open the binding face of blade, therefore avoids the adverse current of liquid in bag.
