Technical field
The utility model relates to a kind of acquisition device, in particular to a kind of disposable saliva protects acquisition device.
Background technique
With the fast development of domestic and international medical level, in recent years, institute is detected to human body fluid by each medical inspection testing agency
The instrument of use and more stringent requirements are proposed to the accuracy of testing result；Again in clinical medicine detection, to understand patient
Health index, it is often necessary to acquire clinical samples, detect its data and referred to as clinical diagnosis, common sample has blood
Liquid, saliva and urine etc.；The medical worker that acquisition blood needs profession has carried out traumatic donor source to patient, gives
Patient causes certain pain and easily causes the transmission of haematogenous, then can be by patient certainly for saliva and urine
Row acquisition and preservation, and hurtless measure, without pain, operation is also extremely convenient, but can not acquire whenever and wherever possible relative to urine,
It is restricted in time and location, and saliva can then be sampled whenever and wherever possible.
In recent years, saliva is detected medical inspection method popular as one and is gradually risen, and it is complete to there is reflection in saliva
The biomarker of body health status contains a large amount of biological information, such as contains various protein, DNA, fatty acid
And other microorganisms；The study found that various protein components also exist in saliva in blood, saliva can reflect blood
In various protein levels variation, important information can be provided for clinical diagnosis.
The detection of saliva first must be acquired and be saved, but existing acquisition method and preserving type are not perfect, for example, making
It is directly picked in patient oral cavity with cotton swab, since institute's collection capacity is few, is unable to satisfy clinical demand, and be completely exposed to air
In, it is easily contaminated, salivary component in the short time is made to change to affect testing result；Equally, with plastic cup
Unavoidable saliva contacts with air, in view of the above-mentioned problems, some start with the receiving flask with lid, but air cannot in bottle
It excludes, saliva in bottle is equally also made to be affected during storage.
Summary of the invention
The utility model provides a kind of disposable saliva protection acquisition device, can solve saliva acquisition in the prior art
What device there is a problem of being easily contaminated and gone bad using more inconvenient, saliva.
A kind of disposable saliva protection acquisition device, comprising:
Inert gas or nitrogen is arranged inside for storing saliva in test tube；
Rubber stopper, for blocking the opening of the test tube；
Sting device comprising funnel and puncture outfit, the lower end of the funnel are connected to the puncture outfit, the puncture outfit
Including puncture post and the circumferential wing plate for being uniformly arranged on the puncture post side, the wing plate has far from the end of the funnel
The inclined-plane gradually tapered up to the direction far from the funnel, the puncture post gradually contract along the orient diameter far from the funnel
It is small, runner is offered in the puncture post, described runner one end, which is penetrated through to the side wall of the puncture post, the other end, to be penetrated through to described
In funnel.
More preferably, the rubber stopper has interconnecting piece, and the upper end of the test tube offers external screw thread, opens on the interconnecting piece
Equipped with the internal screw thread matched with the external screw thread, the rubber stopper, which is connected through a screw thread, to be arranged in the test tube port.
More preferably, the side of the funnel is provided with shield, and the shield is set along the extending direction extension of puncture post
It sets and is accommodated puncture post completely, the rubber stopper and the test tube can be accommodated in the shield, the protection
Cover is made of transparent material.
More preferably, further include rubber base, be provided with the maintaining part for wrapping test tube bottom, the rubber base
Bottom offers adsorbent chamber, for generating negative pressure to be adsorbed on body surface.
More preferably, scale is provided on the funnel.
More preferably, filter screen is provided in the funnel.
The utility model provides a kind of disposable saliva protection acquisition device, by being in vitro full of inert gas, saliva
, can be rotten against pollution and oxidation by air under the protection of inert gas after liquid is sent into test tube, influence detection accuracy；It utilizes
Puncture outfit can be convenient ground pierces through rubber stopper, avoid the problem that needle-shaped sting device since rigidity is small, easily snaps off, due to runner
The side wall of puncture post is extended to, puncture post first can be partially penetrated into rubber stopper to block runner, prevents saliva during acquisition
Liquid stream goes out, and at this time since rubber stopper blocks runner, it can be to avoid the evolution of inert gas in test tube and the entrance of air, saliva
Liquid is spat into after funnel to be continued to be pierced into rubber stopper so that runner opens wide in perforation to test tube by puncture post again, and whole process is kept away completely
The evolution and air for having exempted from inert gas enter in test tube, can effectively save saliva for a long time.

Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this
The protection scope of utility model is not limited by the specific implementation.
Embodiment one: as shown in Figures 1 to 5, a kind of disposable saliva protection acquisition provided by the embodiment of the utility model
Device, comprising:
Inert gas 11 or nitrogen is arranged inside for storing saliva in test tube 10；
Rubber stopper 12, for blocking the opening of the test tube 10；
Sting device 20 comprising funnel 21 and puncture outfit 23, the lower end of the funnel 21 are connected to the puncture outfit 23,
The puncture outfit 23 includes puncture post 232 and the circumferential wing plate 231 for being uniformly arranged on 232 side of puncture post, the wing plate
231 ends far from the funnel 21 have the inclined-plane gradually tapered up to the direction far from the funnel 21, the puncture post 232
It is gradually reduced along the orient diameter far from the funnel 21, runner 233, the runner 233 1 is offered in the puncture post 232
Side wall, the other end of end perforation to the puncture post 232 are penetrated through to the funnel 21.
Embodiment two: on the basis of example 1, the rubber stopper 12 have interconnecting piece 121, the test tube 10 it is upper
End offers external screw thread, and the internal screw thread matched with the external screw thread is offered on the interconnecting piece 121, and the rubber stopper 12 is logical
Threaded connection is crossed to be arranged in 10 port of test tube.It is threadedly coupled it is possible to prevente effectively from having can when sting device 20 is extracted
The problem of rubber stopper 12 capable of being taken out of together, the evolution of inert gas 11 is avoided, can achieve better sealing.
Embodiment three: on the basis of embodiment one or two, the side of the funnel 21 is provided with shield 22, described anti-
Shield 22 is extended and is accommodated puncture post 232 completely, the rubber stopper 12 and institute along the extending direction of puncture post 232
Stating test tube 10 can be accommodated in the shield 22, and the shield 22 is made of transparent material, since puncture post 232 is complete
It is accommodated in shield 22, therefore can prevent from surprisingly stabbing, shield 22 is made of transparent material, observes with can be convenient
The piercing situation of runner 233, prevent from being pierced into it is too deep cause saliva to spit into funnel 21 before make in the perforation to test tube 10 of runner 233.
Example IV: unlike embodiment three, the present embodiment further includes rubber base 30, is provided with for wrapping up
The bottom of the firmly maintaining part 32 of 10 bottom of test tube, the rubber base 30 offers adsorbent chamber 31, for generating negative pressure to be adsorbed on
