Abstract
The invention discloses an automatic blood plasma separating clip, and belongs to the field of medical apparatus. The automatic plasma separating clip comprises a base, and a fixed plate and a movable plate which are arranged on the base and parallel to each other, wherein a hook for hanging a blood bag is arranged at the upper end of one side of the fixed plate; a power component for driving the opening and closing of the movable plate and the fixed plate is arranged in the base; horizontally stretching waist-shaped holes are formed on two sides of the base; and the lower end of the movable plate stretches into the waist-shaped holes and is connected with the power component. The plasma separating clip has a simple and practical structure, and the friction resistance of a system is reduced and the stability of a device is improved when the clips are arranged in multiple places. The plasma separating clip is convenient to use; and compared with a foreign full-automatic blood separation instrument, the plasma separating clip has the advantage that: production cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of medicine equipment, relate in particular to the automatic plasma-separating clip of a kind of blood.
Background technology
Blood is divided into three layers after centrifugal, be plasma layer topmost, and the bottom is the red blood cell layer, the centre for being called the tunica albuginea layer, mainly comprise blood platelet and leucocyte.Blood constituent through after separating is widely used in clinical treatment.Because each composition in the whole blood plays a different role in human body, sometimes hospital or blood station only need provide one or both compositions of blood to the patient according to the needs of disease treatment, realize the many usefulness of a blood, have better practiced thrift blood resource.Therefore high-quality blood constituent separates and just seems particularly important.
Chinese patent " a kind of blood plasma-separating clip " (patent No. ZL94236708.1) discloses a kind of device of manual extruding separating blood constituents.This device utilizes manually propelling movement and elastic hinge that the blood bag is pushed, operation inconvenience, and also the stability of the arrangement of levers of this patent is not high.
The full-automatic instrument of separated plasma is abroad also arranged now, control automatically through the weight of measuring isolated each component of blood.But these instruments is expensive, uses, the expense of maintenance is very high, is unfavorable in China to public service and promote the use of.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of automatic plasma-separating clip of blood of practicing thrift cost, be used for the whole blood after centrifugal is separated through automatic extruding.
Technical scheme: for realizing above-mentioned purpose; The automatic plasma-separating clip of a kind of blood of the present invention; The fixed head and the portable plate that comprise base, be installed on the base and be parallel to each other, the upper end of said fixed head one side is provided with the hook that is used to hang the blood bag, is provided with the Power Component that drives mutual folding between portable plate and the fixed head in the said base; Said base both sides have horizontally extending waist-shaped hole, and said portable plate lower end extends in the said waist-shaped hole and links to each other with Power Component.
Said portable plate comprises the sliding shoe of crossbearer between two waist-shaped holes, link to each other near the two ends of waist-shaped hole with sliding shoe and cover the stand of base upper surface and be installed in the clamping plate in the stand.
Said Power Component comprises the sliding rail that is used for stablizing portable plate perpendicular to portable plate and the linear stepping motor that links to each other with portable plate and the both sides that are positioned at the linear stepping motor rotor.
The present invention has realized the automatic folding between portable plate and the fixed head through adding linear stepping motor.The rotor of said linear stepping motor crosses the sliding shoe of portable plate and is fixed to the base opposite side from the side that base is equipped with motor body; Be positioned at the rotor outer end at base and be provided with the deep groove ball bearing that is socketed in outside the rotor, play the effect that reduces frictional resistance.
Only depend on the rotor supports portable plate can cause swinging of portable plate,, therefore added two rail plates that parallel in order to improve the stability of portable plate.Simultaneously, for the frictional resistance of sliding shoe on rail plate that reduces portable plate, the place of corresponding two sliding rails of said sliding shoe is embedded with and is socketed in the outer linear bearing of sliding rail.The place of said sliding shoe line correspondence stepping motor rotor has the hole, is provided with the screwed flange that is socketed in outside the linear stepping motor rotor and is fixed on the sliding shoe side in the said hole.When the rotor rotation of linear stepping motor, drive portable plate and move through being fixed on screwed flange on the sliding shoe.The precision of this type of drive, stability height.
Said stand has near a side of fixed head is convenient to the transverse groove that the descending conduit of blood bag stretches out.Like this when portable plate and fixed head close up extruding blood bag, the descending conduit of blood bag can overflexing, influence the interior flow of pipeline.
When preventing that portable plate and fixed head from closing up, hinder and close up thereby the hook of fixed head arrives to portable plate, the place of the corresponding hook of said clamping plate has groove.
As further optimization of the present invention, the said fixed head and the clamping plate outside are provided with reinforcement.Said fixed head and clamping plate all are fixed head and the clamping plate that adopt the PVC plastic material to process.
Beneficial effect: the automatic plasma-separating clip of a kind of blood of the present invention is simple in structure, practical, has more the stability that design has reduced the system friction resistance and improved device.Plasma-separating clip of the present invention is very easy to use, and compared to external fully automatic blood separate apparatus, production and the cost that uses reduce widely.
