The device comprises a blood storing bottle, wherein the blood storing bottle is cylindrical; a blood corpuscle and blood plasma separator is arranged in the blood storing bottle, can slide upwards and downwards in the blood storing bottle, and comprises a piston rod; the piston rod is tubular, and a sealing plug is fixed on an open part of the piston rod which extends into a part of the blood storing bottle; a reverse osmosis film is arranged on the sealing plug which is opposite to the pipe orifice of the piston rod; and the outer diameter of the sealing plug corresponds to the inner diameter of the blood storing bottle. Compared with the prior art, the blood corpuscle and blood plasma separating device for trace blood collection has the characteristics of reasonable design, simple structure, convenience in using and the like, has a wide application range, is simple and rapid in a blood corpuscle and blood plasma separating process, and can be used for separating blood corpuscle from blood plasma at the normal temperature and under a constant pressure, and the working difficulty of inspection personnel can be effectively lowered.
Description
Technical field
The utility model relates to a kind of medical treatment and detects apparatus, specifically a kind of trace blood easy to use blood cell plasma separating unit.
Background technology
At present, the finger trace blood is generally adopted by clinical examination, namely with behind the spike pierces finger, firmly pinches micropipet and draws blood sample, and blood sampling will be separated the serum in the whole blood or blood plasma after finishing with the composition that contains blood cell.As one of method of separating, have at the blood of the material that has been equipped with the middle proportion with serum etc. and blood cell composition and take to take in the pipe whole blood sample, make this material be positioned at the centre position of serum etc. and blood cell composition by centrifugation operation, thus the method for separating.But this method need to use instrument to finish, and can not carry out at normal temperatures blood and separate, thereby it is necessary designing a kind of easy device of can normal temperature separating blood cell blood plasma.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, trace blood blood cell plasma separating unit is provided.
The technical solution of the utility model realizes in the following manner, a kind of trace blood blood cell plasma separating unit, its structure comprises the blood storing bottle, this blood storing bottle is long tubular, the built-in blood cell plasma separator of described blood storing bottle, this blood cell plasma separator can slide up and down in the blood storing bottle, described blood cell plasma separator comprises a piston rod, piston rod in a tubular form and its stretch into blood and place opening portion of bottle part and be fixed with sealing-plug, at the sealing-plug place relative with the piston rod mouth of pipe one reverse osmosis membrane is set, described sealing-plug external diameter is corresponding with the internal diameter of blood storing bottle.
Further, the seal cover that can slide up and down along the piston rod inwall at described piston rod built-in, sealing lid from top to bottom order comprises gland, sealing, tightening latch, isolation bolt, the gland diameter is far longer than the diameter of sealing, and the design seal cover is destroyed in transit in order to prevent blood sample.
As preferably, described sealing is column and its external diameter is corresponding with the internal orifice dimension of piston rod, and sealing just can be realized the sealing to piston rod part like this.
As preferably, to isolate bolt and be designed to a round and elastic transparent plastic sheet, the isolation bolt is that whether the design of transparent sheet is to carry out smoothly in order to observe clearly in use isolated instances with blood cell and plasma separation after separating.
The beneficial effect that the utility model compared with prior art produces is:
A kind of trace blood of the present utility model with the blood cell plasma separating unit have simple in structure, easy to use, the characteristics such as be skillfully constructed, blood cell plasma separation Simple fast, can level pressure separate blood cell and blood plasma under the normal temperature, the working strength that effectively reduces a staff, compare with other separate apparatus, of the present utility model cheap for manufacturing cost, have good value for applications.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Mark in the accompanying drawing represents respectively:
1, gland, 2, piston rod, 3, the blood storing bottle, 4, reverse osmosis membrane, 5, sealing-plug, 6, the isolation bolt, 7, tightening latch, 8, sealing.
The specific embodiment
Below in conjunction with accompanying drawing a kind of trace blood of the present utility model is described in detail below with the blood cell plasma separating unit.
As shown in Figure 1, a kind of trace blood blood cell plasma separating unit, its structure comprises blood storing bottle 3, this blood storing bottle 3 is long tubular, described blood storing bottle 3 built-in blood cell plasma separators, this blood cell plasma separator comprises a piston rod 2, piston rod 2 in a tubular form and its front opening by sealing-plug 5 sealing, sealing plug 5 is by described piston rod 2 mouths of pipe of a reverse osmosis membrane 4 sealings, the inner tube wall close contact of described sealing-plug 5 and blood storing bottle 3, that is to say that described sealing-plug 5 external diameters are corresponding with the internal diameter size of blood storing bottle 3.
Described piston rod 2 built-in seal covers, sealing lid from top to bottom order comprises gland 1, sealing 8, tightening latch 7, isolation bolt 6, described sealing 8 is column and its external diameter is corresponding with the internal orifice dimension of piston rod 2, and isolation bolt 6 is designed to a round and elastic transparent plastic sheet.
The 270 μ l that in blood storing bottle 3, pack into first during use adjust in advance can with the solution of the absorbance reaction of detecting instrument, to adopt to such an extent that blood places this solution, then by fully stirring, the detection material of adhering on the blood cell is sneaked in the solution, why stir be because in the trace detection plasma fraction to sneak in the solution be very important.Then press the blood cell plasma separator, along with piston rod 2 is pressed, slightly yellowish transparent blood plasma will enter into the inner tube of piston rod 2 toward floating by reverse osmosis membrane 4, has realized that level pressure is separated blood cell and blood plasma under the normal temperature.Be in contact with one another for fear of the blood cell and the blood plasma that in transportation, have separated, must be with 6 sealings of isolation bolt, be transported to inspection center after, pull out seal cover after, blood storing bottle 3 remained untouched to be placed on the detecting instrument and can to detect.
In the above-described embodiments, preferred forms of the present utility model being described, obviously, under inventive concept of the present utility model, still can make a lot of variations, is several layers of special film and one deck reverse osmosis membrane composition etc. such as the internal structure of piston.Therefore, should illustrate that any change of making all should fall in the protection domain of the present utility model under inventive concept of the present utility model.
