Abstract
The utility model discloses a liquid sample acquisition device. The liquid sample acquisition device is characterized by comprising a sampler chamber body (1), wherein a piston is sheathed in the sampler chamber body (1) and moveably connected with a hollow connecting rod (2), a syringe needle joint (4) is arranged at the front end of the hollow connecting rod (2), and a sample channel (8) in the hollow connecting rod (2) is communicated with the sampler chamber body (1) by a piston puncture tube (5). The liquid sample acquisition device is simple to operate and consumes fewer materials, samples are safer after acquisition, and environmental pollution is reduced.
Description
Technical field:
This utility model relates to a kind of liquid sample collecting device, is mainly used in the collection to liquid sample of medical institutions or scientific research institution.
Background technology:
Often need to gather human or animal's blood or body fluid in medical institutions or scientific research institution, present method is: at first with syringe blood or body fluid are extracted out in the patient body, and then got to blood or body fluid in vitro stand-by from syringe.The drawback of this method is: (1) step is many, has increased staff's working time.(2) link of sample process increases, and the contaminated probability of sample increases.(3) test tube that is adopted does not have seal cover mostly, and the safety and the rodability of sample reduce greatly, and sample in vitro has by the probability of contamination by dust, sample in vitro moisture can volatilize unfavorable to follow-up testing result.(4) after sample used, syringe and test tube all went out of use, and increased the pollution to environment.
The utility model content:
The purpose of this utility model be to overcome the deficiency of above-mentioned prior art and provide a kind of simple to operate, consumable material still less, safer after the sample collection, the liquid sample collecting device that reduces environmental pollution.
The purpose of this utility model can reach by following measure: a kind of liquid sample collecting device, it is characterized in that it has the sampler cavity, be with piston in the sampler cavity, piston and hollow connecting rod flexibly connect, the front end of hollow connecting rod is provided with the syringe needle joint, and the sample channel in the hollow connecting rod communicates with the sampler cavity by the piston puncture tube.
In order further to realize the purpose of this utility model, described piston is made up of piston only and piston brace rod retaining mechanism, and the hollow connecting rod embeds in the piston brace rod retaining mechanism by its rear end and is connected with piston.
In order further to realize the purpose of this utility model, described piston is made by elastomeric material.
In order further to realize the purpose of this utility model, the front portion of described hollow connecting rod is provided with the sampling handrail.
Compared with the prior art this utility model can produce following good effect: this utility model can directly be collected the liquid of gathering in the sampler cavity, and operating process is simple, step is few, has reduced staff's working time; The link of sample process is few, and sample can be not contaminated; And the sample of being gathered directly can be sealed in the sampler cavity, the safety and the rodability of sample improve greatly, and sample is not by the probability of contamination by dust, and sample can not influence follow-up testing result because of moisture evaporation yet in the sampler cavity; The sampler cavity can be used as common test tube and uses, and reduces the pollution to environment.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment: the specific embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: a kind of liquid sample collecting device (referring to accompanying drawing), it has sampler cavity 1, the profile of sampler cavity 1 is similar to common test tube, be with piston in the sampler cavity 1, piston is made up of piston only 6 and piston brace rod retaining mechanism 7, piston only 6 is connected as a single entity with piston brace rod retaining mechanism 7, the rear end of hollow connecting rod 2 embeds in the piston brace rod retaining mechanism 7, piston brace rod retaining mechanism 7 plays the effect that connects piston and hollow connecting rod 2 when sampling, after the sampling, can be used as the handle use of piston being extracted the sampler cavity.Piston plays sealing and locking hollow connecting rod during sampling, and after the sampling, the block that piston can be used as sampler cavity 1 uses.The front end of hollow connecting rod 2 is provided with syringe needle joint 4 (Luer joint), and the Luer joint can be installed various general syringe needle.The front portion of hollow connecting rod 2 is provided with sampling handrail 3.Sample channel 8 in the hollow connecting rod 2 communicates with sampler cavity 1 by the piston puncture tube 5 that passes piston.
Sampler cavity, hollow connecting rod, piston can adopt the method one-shot forming processing of die sinking injection moulding, and wherein sampler cavity and hollow connecting rod should adopt suitable transparent or semitransparent engineering plastics, and piston should adopt the rubber elastomeric material to make; The piston puncture tube should adopt suitable stainless steel tube.Directly annotate together or stick with glue after the injection moulding when piston puncture tube can adopt injection moulding with being connected of hollow connecting rod and connect.Fit together after sampler cavity, piston brace rod and piston machine, be finished product after sterilization and the packing.
During use, on luer joint 4, load onto earlier suitable syringe needle, confirm that piston is in sampler cavity 1 bottom; Behind the position that syringe needle arrival needs to sample, buttress sampling handrail 3 on the other hand, the another hands drags sampler cavity 1 and moves backward, and so just formation negative pressure in sampler cavity 1 needs the liquid of collection to flow to sampler cavity 1 under the effect of negative pressure; Behind the sample that collects suitable volumes, syringe needle is extracted; Allow the syringe needle direction upwards, pulling on the empty connecting rod 2 of disorder of internal organs moves upward, when piston brace rod retaining mechanism 7 is drawn out sampler cavity 1, this retaining mechanism opens and discharges hollow connecting rod 2, because the friction of piston and sampler cavity 1 is greater than the friction of piston puncture tube 5 and piston only 6, piston puncture tube 5 is extracted from piston only 6, and piston is stayed the outlet position of sampler cavity 1 with 1 sealing of sampler cavity; Hollow connecting rod and syringe needle is discarded, and 1 of sampler cavity can be used as common test tube and uses.
