Abstract
The invention discloses a puncture sampling device for hemorheology detection. The puncture sampling device comprises a sampling needle and a blood sample vessel, wherein the sampling needle is connected with a sampling needle drive device, blood sampling is finished through the sampling needle drive device, and the blood sample vessel is a vacuum blood sampling tube. The sampling needle is provided with a sampling tube hole and a pressure balance tube hole; when blood sampling is conducted, an inlet end of the pressure balance tube hole is located outside a tube cap of the vacuum blood sampling tube, and multiple layers of filter nets are arranged in the inlet end of the pressure balance tube hole. Preferably, the filter nets are made of sterile gauze, and the pressure balance tube hole is of a stepped hole structure; the diameter of an inlet section of the pressure balance tube hole is larger than that of an outlet section of the pressure balance tube hole; the filter nets are arranged in the inlet section. The puncture sampling device has the benefits that a blood sample is free of pollution, the resistance to sampling is low, the structure is simple, and manufacturing and use costs are low.
Description
Technical field
The present invention relates to a kind of lectin from hemolymph checkout equipment, particularly a kind of lectin from hemolymph detects puncture sampler.
Background technology
Hemorheology is an emerging biomechanics and biorheology branch, it is research blood macroscopic view flowing property, the flowing of humans and animals body inner blood and cytomorphosis, and blood and blood vessel, heart interphase interaction, a science of haemocyte flowing property and biochemical composition.It is that recent two decades just develops into an independently emerging frontier branch of science.Current lectin from hemolymph is detected and is undertaken by lectin from hemolymph checkout equipment, and it specifically adds anti-coagulants being captured in vacuum test tube inner blood, after mixing, adopts puncture needle sampling.But existing puncture needle is only provided with sampling pore, during sampling, need the block of vacuum test tube to take down to form open-top receptacle, this sampling mode easily causes blood contamination.For this reason, need to improve.
Summary of the invention
The present invention seeks to for the deficiencies in the prior art, a kind of lectin from hemolymph is provided to detect puncture sampler, the sampling probe of this device is provided with sampling pore and pressure equilibrium pore, sampling probe inserts in vacuum test tube by puncture mode and samples, its sample of blood is stored in closed vacuum test tube, eliminate the pollution hidden trouble of blood sample in sampling link, and sampling smoothly.
For achieving the above object, the present invention adopts following technical scheme.
A kind of lectin from hemolymph detects puncture sampler, and comprise sampling probe, sample of blood vessel, sampling probe is connected with sampling probe drive unit, and completes blood sampling by sampling probe drive unit, and described sample of blood vessel are vacuum test tube; Described sampling probe is provided with sampling pore and pressure equilibrium pore, and when blood sampling, the entrance point of pressure equilibrium pore is positioned at the pipe cap outside of vacuum test tube, and its inside is provided with multistorey strainer mesh.
Adopt the present invention of preceding solution, because the vessel depositing blood sample are vacuum test tube, blood sampling carries out in the pipe of sealing, eliminates the pollution hidden trouble of sampling element; Wherein, the pressure equilibrium pore on sampling probe to supplementary pressure in pipe by multistorey strainer mesh, to reach pressure equilibrium, is eliminated the sampling resistance that in sampling process, in pipe, negative pressure causes, is reached and sample object smoothly.
Preferably, described pressure equilibrium pore is stepped hole structure, and its inducer diameter is greater than outlet section; Described filter screen is located in inducer.Filter screen can be avoided by negative pressure tail pipe, guarantee that sampling smoothly further.
Preferably, described filter screen is made up of antiseptic gauze.Antiseptic gauze is drawn materials conveniently, and manufacturing cost and use cost is low, and is convenient to change.
The invention has the beneficial effects as follows, sample of blood is pollution-free, and sampling resistance is little, and structure is simple, and manufacturing cost and use cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated, but therefore do not limit the present invention among described scope of embodiments.
See Fig. 1, a kind of lectin from hemolymph detects puncture sampler, and comprise sampling probe 1, sample of blood vessel 2, sampling probe 1 is connected with sampling probe drive unit 3, and completes blood sampling by sampling probe drive unit 3, and described sample of blood vessel 2 are vacuum test tube; Described sampling probe 1 is provided with sampling pore 11 and pressure equilibrium pore 12, when blood sampling, the entrance point of pressure equilibrium pore 12 is positioned at the pipe cap outside of vacuum test tube, pressure equilibrium pore 12 is in stepped hole structure, its inducer diameter is greater than exducer diameter, and inducer inside is provided with the filter screen 12a that multiple ply sterilization gauze is made.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
