Description
Technical field
The utility model is related to field of medical device, and in particular to a kind of Blood culture bottle that bottle cap is linked together with bottle,
Bottle cap and bottle need not can separately be carried out to the Blood culture bottle of injection and the sampling of blood sample, bottle cap is not required to sterilize again
After use, integral asepsis is closed after rotation, prevent outside contamination may.
Background technology
Blood culture is one of most important inspection project in clinical medicine laboratory, and almost all of disease is such as a variety of thin
Bacterium infectious disease, pneumonia, meningitis, urinary system infection contamination, peritonitis, osteomyelitis, postpartum pyemia, bacterial endocarditis and
The patient etc. of fever of unknown may cause bacteremia, septicemia because bacterium enters blood.And this is serious and critical complete
Body sexuality contaminates, and is badly in need of finding out the pathogen in blood as early as possible, to give targetedly antibacterial therapy in time.Therefore, accurately and timely
Blood culture result is extremely important.Blood culture bottle used at present has two major classes, i.e., manual bottle and upper engine room.Wherein
Upper type Blood culture bottle not only higher price, and be to be matched with special instrument, and these special instruments are very expensive, because
This domestic hospitals is widely used that manual type Blood culture bottle.
Manual type Blood culture bottle existing at present is mainly diphase blood culture flask, nutrient broth class Blood culture bottle (also referred to as list
Phase Blood culture bottle), whether have in bottle bacterial growth need professional judgement by rule of thumb and blind kind, allow for observation knot in this way
Fruit is inconvenient, observes heavy workload, and observation parallax error is big.
The Blood culture bottle especially used is disposable outer cover, and bottle cap outer surface exposes after opening, cannot repeat cover back, bottle stopper
For rubber material, after syringe needle penetrates and squeezes into blood specimen, bottle stopper has surface of a wound gap, this surface of a wound gap is exposed to the external world
In environment, it is colony culture medium in Blood culture bottle, pollution risk is significantly greatly increased, causes blood culture error result, such as false positive knot
Fruit or environment flora rather than the flora growth of blood stream of patients's infection, this can cause the misdirection to clinical treatment medication, less serious case
Delay treatment, severe one jeopardize patient vitals.

Specific implementation mode
The utility model technical problem, technical solution and advantage are illustrated by reference to exemplary embodiment.However, this practicality
It is novel to be not limited to exemplary embodiment as disclosed below, it can be realized by different form.
A kind of Blood culture bottle of one embodiment of the utility model, as shown in Figure 1, including bottle 1 and bottle cap, bottle 1
Interior to carry negative pressure, 4 outer wall of bottleneck is equipped with external screw thread 6, and the inner wall of bottleneck 4 is equipped with the annular clamping groove of ring inner wall setting
9；Bottle cap and 4 mating setting of bottleneck, including inner cover 3 and outer cover 2, inner cover 3 are sealing-plug, surface stacking be coated with aluminium flake film and
Consider bacterium film, meanwhile, it is additionally provided on outer wall and coordinates embedded clamping protrusion 8 with above-mentioned clamping groove 9, clamping protrusion 8 is around interior
The outer wall of lid 3 is arranged；The inner wall of outer cover 2 is equipped with internal thread 7, and internal thread 7 is spirally connected with the external screw thread 6 on 4 outer wall of bottleneck, the two
Between be equipped with sealing consider bacterium film；It is rotatablely connected by rotation slot between the lower end and the outer wall of bottleneck 4 of outer cover 2, the two can not
Dismounting；
In order to be easy to sample, inner cover 3 is penetrated through from upper end to lower end is equipped with thief hole, and probe tube 5 is equipped in the thief hole,
Outer cover 2 is equipped with the exit orifice with thief hole rotatable engagement, and outer cover 2 counterclockwise turn around by rotation, thief hole and exit orifice face, outer cover 2
A circle is rotated clockwise, thief hole interlocks with exit orifice, and thief hole is closed by outer cover 2.
By the Blood culture bottle of above-mentioned offer, the bottle cap of Blood culture bottle need not be opened directly to expose to the open air and be led on experimental bench
Cause can not recycle, but by directly rotate outer cover 2 by the thief hole being arranged on inner cover 3 realize injection blood sample and
Sampling, and since outer cover 2 and 4 outer wall of bottleneck are rotatablely connected simultaneously, also closing connects, so only needing will be on 2 roof of outer cover
Through-hole closing can reach the effect of entire Blood culture bottle sealing.
A kind of Blood culture bottle of one embodiment of the utility model pushes up to improve the leakproofness of inner cover 3 in outer cover 2
Elasticity is connected between the side wall of inner cover 3 consider bacterium diaphragm seal item on the inner wall at end, after rotation that outer cover 2 is counterclockwise is turned around,
Sealing strip is punctured into former length, is located at the side of inner cover 3；After outer cover 2 rotates clockwise a circle, sealing strip is stretched will be on inner cover 3
Thief hole top closure.Since the sealing strip has elasticity, stretched so elasticity can be carried out while as outer cover 2 rotates
Contracting, when opening thief hole, sealing strip can return back to original length, and when by sampling bore closure, sealing day, which can be stretched, to be close to
On thief hole.
In order to improve the retractility of sealing strip, being unlikely to when flexible between inner cover 3 can not be real due to larger friction
Now normally elongation or elasticity are restored, and one end of preferably sealing strip is fixed on the center of the inner wall on 2 top of outer cover, the other end
It is fixed on the side wall of outer cover 2.In order to improve the leakproofness of bottle 1, the preferably side wall of inner cover 3 is equipped with the outer rim of bottleneck 4
The extension of package, extension is arranged around the outer wall of inner cover 3, parallel with the upper end of bottleneck 4, is wrapped in the outer rim of bottleneck 4.In order to
Convenient for closing the through-hole on 2 top of outer cover, preferably the roof of outer cover 2 is equipped with the placement for placing multiple sealing joint strips 10
Setting is pasted in slot, the stacking of multiple sealing joint strips 10, and when use only needs to take a sealing joint strip 10 off and can close exit orifice.
More than, although the description of several embodiments of the utility model, but these embodiments are intended only as example
It proposes, is not intended to limit the scope of the utility model.For these new embodiments, can with various other ways into
Row is implemented, and in the range of not departing from the main idea of the utility model, can carry out various omissions, displacement and change.These are implemented
Mode and its deformation, while being contained in the scope of the utility model and main idea, are also contained in described in claim
