Description

Disposable blood sample aseptic collection culture flask

The utility model belongs to the clinical examination utensil, mainly proposes a kind of disposable blood sample aseptic collection culture flask.

Normal human's blood is aseptic, infects when whole body is sent out and general infection occurs when the part, bacterium can occur in the blood; The blood cultivation technology not only can confirm bacteremia or septicemia, and can instruct the selection of clinical microbiotic to treat timely and effectively, the blood microbe growth is a routine work of hospital inspection, but continue to use traditional method for a long time: quantitatively be loaded on the glass triangle flask after earlier nutrient solution being prepared always, clog bottleneck with homemade gauze tampon, bottle stopper is wrapped up in packing sheet or paper outward to bottleneck, fraps, and the rearmounted refrigerator of autoclaving is preserved stand-by.Operation must be carried out culture flask and spirit lamp during collecting blood sample before patient bed, venous blood collection method routinely, after quantitatively extracting blood with asepsis injector, above spirit lamp flame, untie the culture flask jag, the bottle support with favored policy, carefully open bottle stopper, remove syringe needle then, blood is slowly injected in the culture flask, behind the bottleneck flame sterilization, again the bottleneck jam-pack is tied, take back section office and cultivate, when needing transferred species or plate coating checking in the incubation, must when opening bottle stopper, hold oese picking culture in addition.There is complex steps in this classic method and just use the structure of utensil, and operation is wasted time and energy, especially the defective that easily pollutes in the operating process.

The purpose of this utility model promptly is to propose a kind of disposable blood sample aseptic collection culture flask, makes it can finish blood collection smoothly and cultivates the transferred species program, have simultaneously simple in structure, easy operating and stop pollution characteristics.

The utility model is finished the technical scheme that its invention task taked: its main body is the plastic culture bottle of hard transparent, has built-in conduit on the bottle cap that combines and adopt the O-ring seal sheet to seal with whorl of bottleneck with its one, the conduit lower end is positioned at bottle and connects the stainless steel oese at opening part, it is bottle cap, built-in conduit, oese is connected as a single entity, built-in conduit upper end is positioned at bottle cap top and connects flexible blood sampling conduit by joint, the blood sampling catheter proximal end connects the venous blood collection syringe needle, thereby culture flask and hemostix are integrally combined, make hemostix, conduit, bottle, oese constitutes the sealed whole body structure.

The utility model use: divide and nutrient solution is housed and has sealed the transparent plastic triangular flask that extracts negative pressure, to the ward collecting blood sample, tourniquet and with after the conventional method sterilization on the bundle, when the thorn blood vessel is seen the conduit blood back, the blood sampling catheter clip of loosening immediately, because the effect of the interior negative pressure of vein pressure and culture flask, blood can successfully flow in the interior nutrient solution of bottle along blood sampling conduit and built-in conduit, can be according to the containing mark control blood sampling volume of triangular flask; Blood sampling finishes, hemostix is separated with built-in pipe joint on the bottle cap from the blood sampling conduit, simultaneously the lancet end protective cover is enclosed within the built-in pipe joint immediately, taking back Bacteriology Room cultivates, in incubation as must transferred species or plate coating checking, the sealing film of bottleneck is cultivated in unpacking, be that available built-in oese picking culture carries out transferred species or plate coating checking in the bottleneck of outwarding winding, but flame sterilization after the stainless steel oese is used, again inserting bottle inward turning upper bottle cover continues to cultivate, culture flask can carry out harmless treatment with other contaminated articles, disposable use after cultivation finished.

Scientific structure design of the present utility model is reasonable, culture flask and the hemostix one that links, and be negative pressure in the bottle, blood collection is very convenient, and in the ward of air dirt, sterile working is definitely reliable, and can quantitatively take a blood sample according to containing mark on the bottle; The built-in oese of the culture flask one that links to each other with bottle cap is that available oese takes out culture when opening bottle cap, and it is quite convenient to use, and it makes the whole operation process become simple orderly, and has fundamentally stopped contamination phenomenon.

Embodiment:

Accompanying drawing 1 is the utility model structural representation:

As shown in drawings: its main body is the plastics triangular flask 2 of hard transparent, quantitative culture liquid is housed interior branch and negative pressure has been extracted in sealing, bottle cap 5 combines and uses O-ring seal with whorl of bottleneck, the sheet sealing, with the impermeability inside and outside the triangular flask that guarantees to screw, has built-in conduit 4 on the bottle cap 5 with its one, built-in conduit 4 can adopt rigid plastic to make, built-in conduit 4 lower ending opening places 3 connect the handle of stainless steel oese 1, in the bottle cap of outwarding winding, can together take built-in oese 1 out of the picking culture, built-in conduit 4 openings 3 and oese 1 exceed the nutrient culture media liquid level in bottle, blood flows into during in order to interior negative pressure of extraction bottle and blood sampling; Built-in conduit upper end is positioned at bottle cap top; has the joint 6 that is connected with heparin tube; it can be a undergauge structure; be inserted in and guarantee excellent contact and impermeability in order to blood sampling conduit 7; blood sampling conduit 7 is the medical transparent plastic hose of high-quality; the front end place establishes a catheter clip 8; culture flask can be with catheter clip 8 chuckings after extracting negative pressure; to guarantee the negative pressure state in the preceding triangular flask of blood sampling puncture; the blood sampling catheter proximal end connects hemostix; it can be identical with existing disposable blood taking device structure, and promptly catheter proximal end connects lancet joint 9, connects venipuncture syringe needle 10; syringe needle (is cone barrel by plastic sheath 11; bore is slightly larger than the built-in pipe joint of bottle cap) protection, blood sampling conduit 7 in blood sampling back can separate from the joint with the built-in conduit of bottle cap, needle guard 11 is enclosed within on the joint of built-in conduit 4; the degree of tightness appropriateness; both can avoid air pollution, can guarantee the inside and outside certain aeration of culture flask again, help microbe growth.

The bottle general assembly after, the blood sampling conduit can coil neatly, with the bungee bundle in the triangular flask bottleneck.

The bottle assembly adopts aseptic external packing transparent bag sealing, reaches aseptic through the integral body of sterilizing.
