Description
Technical field
The utility model relates to a kind of disposable inherent filtration nutrition transfusion bags, belong to medical instruments field.
Background technique
Currently, access of the inlet pipe part of nutrition infusion bag as filling nutrient solution, it usually needs design is biggish
Hole size meets the needs of clinical efficiently filling to improve the filling speed of nutrient solution.But inlet pipe is biggish interior
The problem of larger particles foreign matter is readily incorporated when pore size also brings filling, such as bottle stopper, rubber scraps, these foreign matters are usual
Naked eyes as it can be seen that be suspended among the nutrient solution of bag body, when patient fluid infusion see these foreign matters after can generate the feelings such as anxiety, anxiety
Thread, it is serious or even medical trouble problem occur.
Therefore in process of production, a filter screen can be added in the connector between inlet tube and the inlet of bag body,
Or be welded on filter screen on the connector of bag body inlet, but during filling nutrient solution, filter screen can be by nutrition
Liquid is washed open, is fallen off from original position, and filling unsmooth problem is caused, and when the filter hole on filter screen is blocked by particle foreign matter, is needed
Connector is removed to clean filter screen, and filter screen is welded on the connector of bag body inlet, bag body inlet connects
Head cannot be dismantled due to the requirement of leakproofness, be made troubles for cleaning filter screen.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies of existing technologies, and is provided a kind of disposable
Inherent filtration nutrition transfusion bag, it can remove cleaning by filter screen fixation and when filter screen is blocked, and use
It is convenient and efficient.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is:
A kind of disposable inherent filtration nutrition transfusion bag, including bag body and inlet tube, the bottom of the bag body are set
It is equipped with inlet, the inlet tube is connected by inherent filtration locking device with inlet, and the inherent filtration locking device includes certainly
It filters locked joints and inherent filtration locks connector sleeve, inherent filtration locked joints, the inherent filtration lock are provided on the inlet
Determine the flow-guiding channel that is internally provided with of connector, the outside of the inherent filtration locked joints is provided with external screw thread, on the inlet tube
It is provided with inherent filtration locking connector sleeve, the inner wall of the inherent filtration locking connector sleeve is provided with internal screw thread, the inherent filtration locking
Connector sleeve is internally provided with diversion column, and filter screen is provided at the top of the diversion column, and the diversion column and filter screen are one
Forming structure, the diameter of the diversion column are less than the diameter of flow-guiding channel.
Further, the bottom of the inherent filtration locked joints and inherent filtration locking connector sleeve is provided with revolving fragment.
Further, the outer wall of the inherent filtration locking connector sleeve is uniformly arranged fluted.
Further, the bottom of the bag body is provided with fluid infusion port.
Further, the bottom of the bag body is additionally provided with injecting liquid drug end.
Using above-mentioned technical proposal, the utility model between inlet and inlet tube by increasing inherent filtration locking dress
It sets, the foreign matter in nutrient solution is filtered, inherent filtration locking device can carry out disassembly, cleaning, the mistake in inherent filtration locking device
Strainer is an integral molding structure with diversion column, is connected firmly, easy to use.
