Description

Waste fluid bag
Technical field
The utility model belongs to medical instruments field, more particularly, to a kind of waste fluid bag.
Background technique
Red blood cell washing machine be mainly used for remove Red Blood Cells Concentrate in contain a small amount of blood plasma, leucocyte, blood platelet and Their fragment.Red Blood Cells Concentrate bag is connected into building confined condition with washing consumptive material using sterile tube machine, it will using blood pump Red blood cell is pumped into Centrifuge Cup, drives Centrifuge Cup rotation by centrifuge, the ingredient of different specific weight is centrifugated, solution is then passed through It is pumped into cleaning solution to eluriate red blood cell, to obtain Washed Red Blood Cells.Red blood cell washing needs to adopt during separating Waste liquid is acquired with waste fluid bag.
Application number: 201120221520.7 disclose a kind of waste fluid bag, which includes upper conduit and downcomer, also wrap It includes: air filtration hole.It is arranged on the waste fluid bag.The air filtration hole is set to the top of the waste fluid bag.Close on institute State conduit.Filter medium is provided in the air filtration hole.The filter medium is cellulose acetate filter stick.The waste liquid Bag, can be avoided waste reflux contaminated blood, to guarantee entire Blood calldack process safety operation.
The waste fluid bag air filtration hole of the prior art is set up directly on the side wall of waste fluid bag, is easy blocking and pollution.
Summary of the invention
The waste fluid bag that simple, air filtration hole that the purpose of the utility model is to provide a kind of structures is not easy to plug, it is especially suitable It closes and is applied in red blood cell washing pipeline.
The technical solution of the utility model is:
Waste fluid bag, including bag body, the upper end of bag body are equipped with sealing part, and the middle part of sealing part is equipped with connecting tube and snorkel, Connecting tube and snorkel are respectively perpendicular to sealing part and are heat sealing inside sealing part, and the length of connecting tube and snorkel is greater than sealing part Width, air-filtering membrane is equipped in snorkel.
Air-filtering membrane is arranged in the snorkel of bag body upper end sealing part, is not easy to plug, and it is good that effect is discharged in air.
The lower end of the connecting tube and snorkel flushes below with sealing part.
Internal diameter in the middle part of connecting tube is greater than the internal diameter at connecting tube both ends, and the internal diameter in the middle part of snorkel is greater than snorkel both ends Internal diameter.
The internal diameter that connecting tube and snorkel are located at sealing part interior section increases, and can be avoided connecting tube and snorkel in heat Deformation occurs when conjunction, so as to cause connecting tube and the deflated blocking of snorkel.
The width of sealing part is 1.5-4cm.
Connecting tube and the length of snorkel are respectively greater than the width 0.5-1cm of sealing part.
The width of sealing part can guarantee that connecting tube and snorkel are firmly fixed to sealing part, avoid connecting tube and ventilation Pipe generates the leakage for being displaced and causing waste fluid bag.
Seal convexity is equipped in the middle part of the top of the sealing part, the following of seal convexity is connected with sealing part top, close It seals and is spaced setting between the top and connecting tube and the upper end of snorkel of protrusion, the length of seal convexity is greater than connecting tube and ventilation The distance between pipe.
The utility model has the advantages and positive effects of: adding snorkel in sealing part, air-filtering membrane is arranged Inside snorkel, it can be avoided air-filtering membrane blocking, keep gas pressure balancing in waste fluid bag, be conducive to the addition of waste liquid And discharge.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model waste fluid bag
Fig. 2 is the partial enlarged view of the utility model waste fluid bag
In figure:
1, bag body 2, sealing part 3, connecting tube 4, snorkel 5, air-filtering membrane 6, seal convexity
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model waste fluid bag, including bag body 1, the upper end of bag body 1 are equipped with sealing part 2, sealing The middle part at place 2 is equipped with connecting tube 3 and snorkel 4, and connecting tube 3 and snorkel 4 are respectively perpendicular to sealing part 2 and are heat sealing at sealing part 2 The length of inside, connecting tube 3 and snorkel 4 is greater than the width of sealing part 2, is equipped with air-filtering membrane 5 in snorkel 4.
Air-filtering membrane 5 is arranged in the snorkel 4 of 1 upper end sealing part of bag body, is not easy to plug, and it is good that effect is discharged in air.
Further, the lower end of connecting tube 3 and snorkel 4 is flushed with the following of sealing part 2.
The internal diameter at 3 middle part of connecting tube is greater than the internal diameter at 3 both ends of connecting tube, and the internal diameter at 4 middle part of snorkel is greater than 4 liang of snorkel The internal diameter at end.The internal diameter that connecting tube 3 and snorkel 4 are located at 2 interior section of sealing part increases, and can be avoided connecting tube 3 and ventilation Deformation occurs in heat seal for pipe 4, so as to cause connecting tube 3 and the deflated blocking of snorkel 4.
The width of sealing part 2 is 1.5-4cm.
Connecting tube 3 and the length of snorkel 4 are respectively greater than the width 0.5-1cm of sealing part.
The width of sealing part 2 can guarantee that connecting tube 3 and snorkel 4 are firmly fixed to sealing part, avoid 3 He of connecting tube Snorkel 4 generates the leakage for being displaced and causing waste fluid bag.
It, can be in the top of sealing part 2 in order to further increase connecting tube 3 and snorkel 4 in the firmness of sealing part 2 Portion is equipped with seal convexity 6, and 2 top of following and sealing part of seal convexity 6 is connected, the top of seal convexity 6 and connecting tube 3 and Setting is spaced between the upper end of snorkel 4, the length of seal convexity 6 is greater than the distance between connecting tube 3 and snorkel 4.
One embodiment of the utility model is described in detail above, but the content is only the utility model Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
