Description
Technical field
The utility model is related to medical container technical field, specially peritoneal dialysis liquid bag.
Background technology
At present, when treating acute injury of kidney and chronic renal failure, peritoneal dialysis is the method for effective renal replacement therapies
One of, because its safe and simple, easily operated, expense is relatively low, treatment of the peritoneal dialysis for improving China's uremic patient has
Whether there is alternative effect.Sterile working is needed during peritoneal dialysis treatment, infection is otherwise easily caused to patient, harm patient's is strong
Health, so the air-tightness for device has strict requirements.Substantial amounts of peritoneal dialysis solution is deposited in peritoneal dialysis liquid bag, compared with
Easily it is contaminated by bacterial.Existing peritoneal dialysis liquid bag includes flexible film bag and turnover liquid pipe with liquid reservoir.Due to
Bag and turnover liquid pipe are made from a variety of materials, and turnover liquid pipe is cylinder, when bag is with fluid-through tube gluing, bag film meeting
The wide-angle for producing 90 degree is transferred, so the position of both connections is the place for gap most easily occur.Existing peritoneal dialysis
Liquid bag is in suspension, and the deadweight of peritoneal dialysis liquid bag inner liquid medicine is acted directly on the bond area of bag and turnover liquid pipe, can be gone out
Existing bond area disengages, caused the situation of leakage, in some instances it may even be possible to can cause patient's bacterial infection, cause a series of complication.For
The peritoneal dialysis liquid bag is set to have enough sealings, Chinese patent Authorization Notice No.：CN203555990U, authorized announcement date 2014
On April 23, in, entitled " attachment structure of the transfusion port tube of peritoneal dialysis liquid bag and the valve that fractures " discloses a kind of peritoneal dialysis
The transfusion port tube of liquid bag and the attachment structure for the valve that fractures, including transfusion port tube and the valve that fractures, transfusion port tube and the valve that fractures are used
Rigid plastics.Outer is provided with the top of transfusion port tube, the valve bottom that fractures is provided with outer rim, and the bottom face of outer rim and the top end face of outer are logical
Cross thermoplastic processes seamless connection.Its thinking is the installation gap between elimination transfusion port tube and the valve that fractures, and it is disadvantageous in that
Feed tube is separate with drain pipe, and neither one is accurately positioned；Pass in and out liquid pipe outer section still for circle, turnover liquid pipe with
The turnover of wide-angle makes the link position of turnover liquid pipe and bag connect built on the sand when bag is connected, and tie point easily floats, easily
Leakage causes potential safety hazard；Sealing propertytest is difficult, it is impossible to intuitively find out bag whether gas leakage.
Utility model content
The utility model will overcome peritoneal dialysis liquid bag and the connecting portion of turnover liquid pipe, easily reveal sealing propertytest hardly possible
Deficiency, devises a kind of structure of peritoneal dialysis liquid bag, can effectively increase peritoneal dialysis liquid bag and the connection of turnover liquid pipe
Intensity, makes peritoneal dialysis liquid bag and the connecting portion of turnover liquid pipe be difficult leakage, and the overall tightness inspection of peritoneal dialysis liquid bag
Survey easy.
To solve the above problems, the utility model uses following technical scheme：
A kind of structure of peritoneal dialysis liquid bag, including bag, are disposed on the feed tube of the top edge of bag and go out liquid
Pipe, feed tube connects into an overall structure with drain pipe by connector；One is embedded with the endoporus of drain pipe to fracture valve；Even
Junctor gluing inside bag, bag marginating compartment provided with interior sealing while and during external seal so that in interior sealing strip and outer close
An air chamber is formed between edge sealing, provided with No. two air chambers between the upper surface of connector and the external seal side of bag.
Feed tube is fixed on connector with drain pipe, so feed tube links into an integrated entity with drain pipe, and in bag
On position fix so that convenient install.The valve that fractures is embedded in drain pipe, and both are seamlessly connected, and air is prevented from root
Entrance, make the sealing of structure more preferable.When bag interior sealing side is leaked, an air chamber is flow to outside bag liquid, can be with
Directly find out whether leak by naked eyes.Connector in the inside of bag, the upper surface of connector and the external seal side of bag it
Between provided with No. two air chambers, when the bonding part of bag and connector is leaked, the dialyzate in bag flows to No. two air
Intracavitary, can conveniently visually observe the sealing of bag and connector.
Preferably, connector includes middle roomy portion and the round and smooth head tip for being connected to roomy portion two is constituted, from
And making connector be in fusiformis, the top of head tip extends outwardly to form a connection thin slice.The connection of connector and bag is gentle, keeps away
The wide-angle turnover of vertical circular arc tangential line is exempted from, connection dead angle will not be formed, make connection more firm, the bonding of bag and connector
Place is difficult leakage.
Preferably, the relative edge in roomy subordinate side two is respectively equipped with connection thin slice, connection thin slice is glued respectively to pair
Answer on the bag of side, the connection area of increase connector and bag prevents the connection edge of connector and bag due to bag liquid
Pressure and be deformed, improve both bonding strengths.
Preferably, the valve that fractures has the output port of up-small and down-big taper, output port and the connection of trisection part
Locate section small, stress concentration, the valve that can conveniently fracture, which fractures, to be used.
Preferably, the break-off portion for the valve that fractures is cylinder.The intensity for ensureing break-off portion enough, will not break easily
Split, so that the generation that fractures, while cylinder injection is simple, saves technique in output port and the link position of break-off portion
Cost.
Preferably, side relative with connector in bag is provided with a circular hole, the both sides of circular hole vertically pass in and out liquid pipe
Straight line is provided with axisymmetric two triangle hole, and three holes are separated with bag by the toe of an arc-shaped.Peritoneal dialysis liquid bag makes
Used time convenient hang-up, simultaneously because power is concentrated on the air ring that circular arc is constituted with hole when hanging up, it is to avoid stress concentration, effectively prevents
Only bag is destroyed.
The utility model has the advantages that：
1, bag compartment of terrain provided with interior sealing while and during external seal, so as to form one between interior sealing strip and external seal side
Number air chamber, when interior sealing side is leaked, dialyzate is flowed in an air chamber, can directly find out peritoneal dialysis solution by naked eyes
Whether bag leaks；
2, connector upper surface is provided with No. two air chambers with bag external seal side, when the bonding part of bag and connector occurs
During leakage, the dialyzate in bag flows to No. two air chambers, can conveniently detect the sealing of bag and fluid-through tube.
