Abstract
The invention relates to a device of a medical injector type centrifuge tube and a projecting jacket. Based on a conventional centrifuge tube, a centrifuge tube is designed to be of a structure of an injector sample, a cap is additionally arranged on a conical head in front of the centrifuge tube to play the role of sealing, after sucking the centrifugal liquid, a pull rod is broken at an opening, a projecting jacket is put in the position at which the centrifuge tube is coincident to a groove in the projecting jacket, and the projecting jacket plays the role of fixing. The injector type centrifuge tube has the characteristics that the forward centrifuge and the backward centrifuge are needed to discharge the unnecessary contents, the needed contents of an interlayer can be obtained directly and conveniently, the polluted occasions are reduced, and the concentration of isolates is increased; and the device is mainly used for separating 1-100ml of venous blood to extract blood cells.
Description
Technical field
The present invention relates to the device of a kind of medical syringe type centrifuge tube and protective sleeve.Be on traditional centrifuge tube basis, centrifuge tube be designed to the structure of syringe-like, add forwardly a cap on the conehead; play the sealing effect; pull bar opening position after absorption needs centrifugal liquid fractures, and puts into protective sleeve by the groove anastomosis in centrifugal body and the protective sleeve, and protective sleeve plays fixation.The characteristics of this syringe type centrifuge tube are after needing positive and negative secondary centrifuging, secondary to discharge unwanted composition, directly, obtain easily required intermediate layer composition, reduce the concentration of contaminated chance and raising separator, be mainly used in clinically 1-100ml venous blood separation and Extraction blood platelet.
Technical background
Since Centrifuge Techniques occurred, centrifuge tube also had the effect of fixing centrifugal material and balance centrifugal force except the effect that container is arranged.It mainly is towards the variation of material and two future developments of variation of form along with the development of centrifuge.
The one, there is plastic centrifuge tube the material aspect, the glass centrifuge tube, and steel centrifuge tube etc., for example, the present material of plastic centrifuge tube has polyethylene (PE), Merlon (PC), polypropylene (PP) etc.
The 2nd, in modal various variations, uncovered, that lid is arranged, flat, the bottom of a pan sample is arranged, with perforate, etc.
, still rest on behind the diversified development of centrifuge tube at present in the concept as container, and must be from now on a trend to having the function affect future development concurrently.
Summary of the invention
The present invention is on traditional centrifuge tube basis, centrifuge tube is designed to the structure of syringe-like, and this syringe type centrifuge tube obtains required intermediate layer composition directly, easily after positive and negative secondary centrifuging, secondary are discharged unwanted composition,
Purpose of the present invention, the one, the syringe type centrifuge tube is behind venous blood samples, putting into can be directly centrifugal behind the protective sleeve, needs stretch into outside common centrifuge tube the contaminated problem of secondary that the discarded red blood cell of suction in the common centrifuge tube pipe and supernatant bring in the time of can solving present extraction blood platelet; The 2nd, convenient, practical than existing methods when extracting the blood platelet in intermediate layer, subtract and hematoblastic loss.
The composition of syringe type centrifuge tube (seeing accompanying drawing 1) comprising: 1, conehead 2, syringe type centrifuge tube overcoat 3, syringe type centrifuge tube piston 4, syringe type centrifuge tube pull bar 5, syringe type centrifuge tube overcoat crimping 6, conehead cap 7, protective sleeve.
Feature of the present invention is:
1, combination: piston is connected on the syringe type centrifuge tube pull bar and is integral, and is inserted in the overcoat, and the annexation of conehead and syringe needle or conehead cap is screw type or direct insertion, namely conehead cap or syringe needle through the screw socket lemon or cover on conehead; The conehead position is enclosed within outward on the same axis with the syringe type centrifuge tube at the positive meta (seeing accompanying drawing 1) in syringe type centrifuge tube overcoat the place ahead, also can be the conehead position at the inclined to one side meta in overcoat the place ahead, parallel with the axis of syringe type centrifuge tube overcoat.
2, the gap that fractures is arranged: syringe type centrifuge tube overcoat, piston, to draw the main body of (core) bar all be cylindrical shape, one gap (seeing Fig. 1) is arranged on the pull bar, the gap degree of depth is the 1/10--9/10 of pull bar cross section half warp, pull bar can fracture through opening position behind venous blood samples by hand, shortens length in order to put into protective sleeve; Gap is apart from plunger distance 5-50mm place.
3, the conehead cap can be screwed in or be inserted on the syringe type centrifuge tube conehead before centrifugal.
4, protective sleeve is arranged: the groove male and female size in centrifugal body and the protective sleeve matches (seeing accompanying drawing 2), the syringe type centrifuge tube is fixed and is difficult for moving up and down, in case the conehead content that fractureed flows out when centrifugal in centrifuge.
The syringe type centrifuge tube also has the further feature of general syringe:
1, the syringe type centrifuge tube can be used as disposable medical article, namely extracts arteriovenous blood after the syringe needle sterilization on the conehead band.
2, the syringe type centrifuge tube can be made into the utensil of the metering specifications at different levels in 1ml to the 100ml scope, and with the graduation mark of standard.
3, between the piston of syringe type centrifuge tube and the syringe type centrifuge tube overcoat, can in suction, move by elastomeric rubber, can also reach the effect of airtight inner chamber.
4, syringe type centrifuge tube overcoat has overcoat crimping (seeing accompanying drawing 1), and conehead is screw socket shape or direct insertion, uses when syringe needle is blood drawing.
5, the material of syringe type centrifuge tube is polypropylene (PP) material or other new material of medical grade, is disposable transparent vessel; Piston is made with medical grade high resiliency, low temperature resistant rubber.
Dimethyl silicone polymer when 7, the syringe type centrifuge tube is made in the usefulness China national pharmacopeia is as lubricant, and consumption is less than every square centimeter of 0.25mg/.
8, the motion of push-and-pull core bar is manual mode.
