A kind of the pre- of no-needle transfusion connector rushes formula catheter flusherTechnical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of the pre- of no-needle transfusion connector rushes the punching of formula conduitWash device.
Background technique
In clinical position, in adjoint various peripheral vein tubulatures, arterial duct and central vein/long duct useIt is universal, nursing staff correctly can effectively rush, tube sealing becomes the important link implemented in catheter manipulation.The injection of formula washing pipe is rushed in advanceDevice as a kind of disposable punching, pipe sealing device, the gap for different pharmaceutical treatment rinses, the line end of closing conduit can be withEffectively pre- anti-blood back prevents the generation of plugging and infection.According to the management in 2016 editions INS guides to vascular access device,Even if before the connection of each vascular access device (including after disinfectant cap is removed), being required in catheter tip application disinfectant capIt with mechanical strength wiping method, is carried out disinfection to no-needle transfusion connector with cotton swab, carries out the operation such as washing pipe again after dry.
Summary of the invention
To solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of the pre- of no-needle transfusion connector and rushes formula conduitFlusher.
The technical solution of the utility model is as follows:
A kind of the pre- of no-needle transfusion connector rushes formula catheter flusher, including syringe, which includes injector cartridgeAnd injector push-rod, injector push-rod front end are equipped with piston, piston is the structure for pushing medical fluid to be injected, the piston and noteIt is piston handle that emitter cylinder, which is combined together to form compressible cavity for storing sterile washing pipe liquid, injector push-rod rear end,；
The injector cartridge front end is connect by hickey with disinfectant cap, is equipped in the disinfectant cap and is compressed and be bondedAseptic cotton on inner wall, an aluminium foil seal disinfectant cap, guarantee that the aseptic cotton in disinfectant cap is in sterile sealing state, this disappearsThe diameter of the disinfection cavity in " recessed " type formed in malicious cap is greater than the end face diameter of no-needle transfusion connector and sterilizes the depth of cavityDegree is equal to the outer end face of no-needle transfusion connector to the distance of cylinder root.
Preferably, the piston is rubber piston.
Preferably, the aluminium foil includes the covering part on top and the tearing end of lower part.
The utility model has an advantage that
1, the utility model is convenient for carrying out no-needle transfusion connector when the gap that different pharmaceutical is treated is rinsed, closes conduitDisinfection reduces general swab stick sterilizing operation bring and sterilizes halfway risk, and mitigate medical staff rush, tube sealingWorking strength when operation reduces medical treatment cost.
2, it is carried out disinfection using the pre- aseptic cotton in disinfectant cap to no-needle transfusion connector, by the elastoplasticity of aseptic cottonDeformation, ties it closely in disinfecting process with the outer end face of no-needle transfusion connector and side, the outer surface of hickey, cylinderIt closes, the sterilization operation that Mechanical Method strength wiping is completed during by screwing on no-needle transfusion connector, screwing out disinfectant cap is wantedIt asks.
3, sterilization operation operation of the endface of disinfectant cap using sealing foil sealing, before farthest reducing washing pipeTime and its labor intensity.

Specific embodiment
Now in conjunction with implementation and attached drawing to the construction of the utility model, shape and the further details of explanation of feature.It should manageSolution, the present embodiment is merely to illustrate the utility model, rather than limits the protection scope of the utility model.
A kind of the pre- of no-needle transfusion connector rushes formula catheter flusher, including syringe, which includes: injector cartridge1, injector push-rod 2,2 front end of injector push-rod are equipped with rubber piston 3, and injector push-rod rear end is equipped with piston handle 4, and rubber is livingPlug 3 and injector cartridge 1 are combined together to form compressible cavity, for storing sterile washing pipe liquid 5.1 front end of injector cartridgeIt is connect by hickey 6 with disinfectant cap 7, the aseptic cotton 8 for compressing and being fitted on inner wall is equipped in disinfectant cap 7, an aluminium foil 9 willDisinfectant cap 7 seals, and guarantees that the aseptic cotton 8 in disinfectant cap 7 is in sterile sealing state, aluminium foil includes the covering part 91 on top underThe tearing end 92 (as shown in Figure 3) in portion, it is defeated that the diameter of the interior disinfection cavity 10 in " recessed " type formed of the disinfectant cap 8 is greater than needlelessThe end face diameter of liquid connector and the depth for sterilizing cavity 10 are equal to the outer end face of no-needle transfusion connector to the distance of cylinder root.
It is the structure chart for being sterilized part no-needle transfusion connector as shown in Figure 4, by the operating instruction of washing pipe, needs to disappear before washing pipeThe part of poison includes: the outer end face and side, the outer surface of hickey 15, cylinder 11 of no-needle transfusion connector 12.Application methodIt is as follows:
Syringe inserts aseptic cotton 8 using preceding in disinfectant cap 7, and the disinfection surrounded by aseptic cotton 8 is formed in disinfectant cap 7Cavity 10, the diameter of the disinfection cavity 10 are slightly larger than the end face diameter of no-needle transfusion connector 12, sterilize the depth and nothing of cavity 10The distance of the outer end face of needle infusion connector 12 to cylinder root 13 is consistent, and disinfectant cap 7 is sealed the sealing of aluminium foil 9, guarantees disinfectant cap 7Interior aseptic cotton 8 is in sterile sealing state, and disinfectant cap 7 passes through the hickey 6 of 1 front end of injector cartridge to sterile washing pipeLiquid 5 is sealed.The lower part tearing end 92 for sealing aluminium foil 9 to disinfectant cap 7 when use, which applies, avulses power as shown in dotted line 14, tearsOpening aluminium foil 1.
The cavity 7 of disinfectant cap 2 is directed at no-needle transfusion connector 12, hold injector cartridge 1 and disinfectant cap 7 is slightly compressed to nothingOn needle infusion connector 12, disinfectant cap 7 is rotated by right-handed helix direction, by the elastic-plastic deformation and hickey 15 of aseptic cotton 8,Disinfecting surface needed for no-needle transfusion connector 12 can be screwed in disinfectant cap 7, rear opposite direction screws out on earth, in the process can be primaryProperty complete for the outer end face of no-needle transfusion connector 12 and side, the outer surface of hickey 15, cylinder 11 sterilization operation, intoDisinfectant cap 7 can be screwed out after row disinfection and carries out washing pipe operation.The utility model disappears when greatly reducing general swab stick sterilizing operationThe halfway risk of poison, while nursery work intensity when alleviating washing pipe and reducing medical treatment cost.
The description of the utility model is merely illustrative above, and not restrictive, those skilled in the art should be managedSolution can carry out many modifications, variation or equivalent modification within the spirit and scope that claim limits to it, but they are allIt will fall into the protection scope of the utility model.
