Abstract
The utility model discloses one and independently use filter for intravenous, for medical instruments field, the feed tube comprising filter and drawn by described filter and drain pipe, described filter interior is provided with filter membrane between described feed tube and drain pipe, the outer end of described feed tube is provided with syringe union joint, and the outer end of described drain pipe is provided with puncture needle union joint.This independence uses filter for intravenous to arrange feed tube and drain pipe on the filter, intravenous injection and when being undertaken infusing by transfusion extension tube clinically, syringe can be connected with feed tube by syringe union joint, puncture needle is connected with drain pipe by puncture needle union joint, so, venous patient is entered after the medicine filter membrane just can be passed through in filter filters, this utility model compact structure, can be applied in various venous transfusion mode neatly, venous transfusion safety can be improved better, and ensure the safety of patient.
Description
Technical field
This utility model is used for medical instruments field, particularly relates to one and independently uses filter for intravenous.
Background technology
Clinical vein infusion safety is more and more subject to people's attention, and precision infusion set is also applied in the infusion of different liquids more and more widely.Requirement in " the venous transfusion nursing practice standard " published according to 2006, enters into the medicines such as the powder in human body, mannitol, has to pass through filtration! But for intravenous injection with when being undertaken infusing by transfusion extension tube, also do not carry out clinically filtering or the device of secondary filter available.
Utility model content
For solving the problem, this utility model provides one can be applied in various venous transfusion mode neatly, improves venous transfusion safety better, ensures that the independence of patient safety uses filter for intravenous.
This utility model solves the technical scheme that its technical problem adopts: a kind ofly independently use filter for intravenous, the feed tube comprising filter and drawn by described filter and drain pipe, described filter interior is provided with filter membrane between described feed tube and drain pipe, the outer end of described feed tube is provided with syringe union joint, and the outer end of described drain pipe is provided with puncture needle union joint.
Be further used as the improvement of technical solutions of the utility model, described filter comprises hollow and the housing of open at one end and can close the end cap of described housing, described housing is provided with the inlet connecting feed tube, described end cap is provided with the liquid outlet connecting drain pipe, described end cap inwall is provided with liquid outlet conducting and the filter membrane stretched in described housing supports rack, and described filter membrane is wrapped in outside filter membrane grid frame supported described inlet and liquid outlet to be separated.
Be further used as the improvement of technical solutions of the utility model, described inlet and liquid outlet are just to coaxial setting, and described filter membrane grid frame supported is vertically stretched out by end cap, and tapers off to a point in the inner side of described inlet.
Be further used as the improvement of technical solutions of the utility model, the sidewall of described housing is provided with some steam vents, and the inwall of described housing is provided with the waterproof ventilated membrane covering each described steam vent.
Be further used as the improvement of technical solutions of the utility model, described end cap and housing are threaded connection, and between end cap and housing, sealing ring are housed.
The beneficial effects of the utility model: this independence uses filter for intravenous to arrange feed tube and drain pipe on the filter, intravenous injection and when being undertaken infusing by transfusion extension tube clinically, syringe can be connected with feed tube by syringe union joint, puncture needle is connected with drain pipe by puncture needle union joint, so, venous patient is entered after the medicine filter membrane just can be passed through in filter filters, this utility model compact structure, can be applied in various venous transfusion mode neatly, venous transfusion safety can be improved better, and ensure the safety of patient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is this utility model embodiment overall structure schematic diagram;
Fig. 2 is this utility model embodiment filter structure schematic representation.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, this utility model provides one and independently uses filter for intravenous, the feed tube 2 comprising filter 1 and drawn by described filter 1 and drain pipe 3, described filter 1 inside is provided with filter membrane 4 between described feed tube 2 and drain pipe 3, the outer end of described feed tube 2 is provided with syringe union joint 5, and the outer end of described drain pipe 3 is provided with puncture needle union joint 6.
Wherein, described filter 1 comprises hollow and the housing 11 of open at one end and can close the end cap 12 of described housing 11, and described end cap 12 and housing 11 are threaded connection, and sealing ring (not shown) is housed between end cap 12 and housing 11.Described housing 11 is provided with the inlet 13 connecting feed tube 2, described end cap 12 is provided with the liquid outlet 14 connecting drain pipe 3, described end cap 12 inwall is provided with liquid outlet 14 conducting and the filter membrane stretched in described housing 11 supports rack 15, and described filter membrane 4 is wrapped in outside filter membrane grid frame supported 15 described inlet 13 and liquid outlet 14 to be separated.Described inlet 13 and liquid outlet 14 are just to coaxial setting, and described filter membrane grid frame supported 15 is vertically stretched out by end cap 12, and taper off to a point 16 in the inner side of described inlet 13.The sidewall of described housing 11 is provided with some steam vents 17, and the inwall of described housing 11 is provided with the waterproof ventilated membrane 18 covering each described steam vent 17, and the air in medicinal liquid can be discharged by steam vent 17, ensures infusion safety.
This independence uses filter for intravenous on filter 1, arrange feed tube 2 and drain pipe 3, intravenous injection and when being undertaken infusing by transfusion extension tube clinically, syringe can be connected with feed tube 2 by syringe union joint 5, puncture needle is connected with drain pipe 3 by puncture needle union joint 6, so, venous patient is entered after the medicine filter membrane 4 just can be passed through in filter 1 filters, this utility model compact structure, can be applied in various venous transfusion mode neatly, venous transfusion safety can be improved better, and ensure the safety of patient.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to this utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
