Abstract
The utility model relates to a leukocyte filtering device, which comprises a soft bag body made from a plastic film, a polyester fiber filtering element, and an inner support. The polyester fiber filtering element is fixed and mounted inside the soft bag body made from the plastic film via the inner support, a liquid inlet is arranged on one side of the bag body, and a filtrate outlet is arranged at the lower end of the bag body. In the leukocyte filtering device, the inner support is fixed inside the bag body, and a filtered blood cavity formed by the inner support and the bag body communicates with the filtrate outlet. The polyester fiber filtering element is effectively supported, so that the blood components before and after filtering are separated.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of disposable use leucocyte-removing filter device.
Background technology
We know that human body blood contains leukocyte, and this leukocyte produces adverse influence to the donee sometimes, cause transfusion reaction in various degree.In addition, during storage, leukocyte also has adverse effect to blood constituent.So blood sampling, blood transfusion process are carried out leukoreduction filter and are very important.The structure of the leucocyte-removing filter that generally uses all is to adopt the filter box of hard plastic injection molding molding now, with the polyester fiber is filter element, with the treated polyester fiber filter element filter box of packing into, adopt ultrasound wave will filter the box welded seal up and down again, runner design in the filter box can effectively prevent side leakage, reaches requirement to guarantee filtration result.
Because at present filter generally all adopts rigid plastics as the filter box, the filter box of hard damages the blood bag when centrifugal, and filter generally can not carry out centrifugal with plastic blood bag connection bag simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of structure reasonable, operation, easy to use can be carried out leukoreduction filter to the blood of gathering, and can carry out centrifugal leucocyte-removing filter device simultaneously with plastic blood bag connection bag.
The technical scheme in the invention for solving the above technical problem is: a kind of leucocyte-removing filter device, it is characterized in that: comprise soft junction structure bag, polyester fiber filter element, inner support that plastic sheeting is made, the polyester fiber filter element is fixedly mounted in the soft junction structure bag of plastic sheeting making, soft junction structure bag one side is provided with liquid-inlet, and the lower end is provided with filtrate (liquid.
The said inner support of this utility model is fixed in the bag, its with filter that bag forms after blood chamber be communicated with filtrate (liquid.Guarantee effective support polyester fiber filter element, be convenient to separating and filtering, make before the filter and filter back blood constituent separately.
This utility model is because defecator is the soft junction structure that plastic sheeting is made, and is very soft, can be centrifugal in the high capacity centrifuge with the connection bag easily after the blood sampling, and carry out blood constituent and separate and leukoreduction filter.Against existing technologies, this utility model can fall the leukoreduction filter the effusive blood in blood donor's body, and its structure is reasonable, operation, easy to use, can carry out leukoreduction filter to the blood of gathering, and can carry out centrifugalize simultaneously with plastic blood bag connection bag.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that sketch map is looked on Fig. 1 left side.
1. bags among the figure, 2. polyester fiber filter element, 3. inner support, 4. liquid-inlet, 5. filtrate (liquid.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of leucocyte-removing filter device of this utility model, it comprises soft junction structure bag 1, polyester fiber filter element 2, inner support 3 that plastic sheeting is made.
This utility model plastic sheeting soft junction structure bag 1 adopts the shell of the thin film identical with the plastic blood bag material as defecator, by heat-seal mould, adopts the high frequency electric of certain intensity and pressure to make film side sealing.Bag 1 one sides are provided with liquid-inlet 4, and the lower end is provided with filtrate (liquid 5.
This utility model polyester fiber filter element 2 adopts polyester fiber to form with filter,plain equally.Polyester fiber filter element 2 is fixedly mounted in the soft junction structure bag 1 of plastic sheeting making by inner support 3.Said inner support 3 is fixed in the bag, and inner support 3 can be by the plastic flexible pipe processing and fabricating, and rounded or oval structure works to support polyester fiber filter element 2.It is divided into filter ante-chamber and filter back blood chamber with polyester fiber filter element 2 with bag, its with the filter of bag formation after blood chamber be communicated with filtrate (liquid 5.Guarantee that filter is preceding and filter the back blood constituent separately, be convenient to separating and filtering, the assurance filter effect.
This utility model can connect bag with plastic blood bag and connect use, adopts high-temperature steam sterilization back to use.Also can adopt oxirane or cobalt 60-γShe Xianmiejun, and the blood bag that need carry out the filtering blood constituent of leucocyte-removing is housed uses by the aseptic back of plugging into.Because defecator itself and connection bag all are membrane structures, and be very soft, can be centrifugal in the high capacity centrifuge with the connection bag easily after the blood sampling, carry out blood constituent and separate.After the separation, blood plasma can prepare fresh frozen plasma.When temperature reaches the filtering optimum temperature requirement of leucocyte-removing (2 ℃～4 ℃), red cell suspension is carried out leukoreduction filter, can satisfy the requirement that blood station or Blood Center prepare fresh frozen plasma and leucocyte-removing simultaneously.This utility model structure rationally, and is easy for operation, is applicable to that disposable blood sampling, leukoreduction filter use.
