Abstract

The utility model relates to a technical field of blood recycling apparatus of medical device, which is designed for enhancing the better effect of filtration and optimizing the structure. The blood recycling apparatus comprises a blood inlet port (1), a blood outlet port (9), a negative pressure absorption socket (4), a blood storage bucket (12), and a filtration mesh bag (11). Wherein, the top of the mesh bag in the blood storage bucket is communicated with the blood inlet port (1) through a blood channel (13), the blood storage bucket is provided with the negative pressure absorption socket (4) on the top, and the blood outlet port (9) is arranged at the lower part. The utility model is characterized in that: a support frame (6) which is enwrapped by a defoaming sponge (7) is arranged in the filtration mesh bag. The utility model has the advantages of maxim storage amount, good defoaming filtration effect, reasonable and compact structure, rapid blood flowing speed, convenient operation, which is adapted to blood recycling for the clinical patients in operation.

Description

Blood collector

Technical field

This utility model relates to blood collector technical field in a kind of medical apparatus and instruments.

Background technology

People are in usual injured or operative treatment, the phenomenon of bleeding profusely runs off in vain for fear of the blood of preciousness, and people have invented the blood retracting device, patients'blood is carried out processing such as vacuum suction, filtration, froth breaking, recovery, import in the human body more again.It as the patent No. 93247338.5 Chinese patent " blood collector ", it has mainly solved present blood source anxiety, the problem that patient with operation catches because of blood transfusion, but its shortcoming, the froth breaking sponge is not set in the filtering mesh bag, fail to make in the blood foam to clear up rapidly, blood is through behind the mesh bag simultaneously, directly crash in the staving, make the blood cell cell pour subject to damage, easily condense in staving, stopping simultaneously, do not have conditioner in the vacuum suction from eminence, be subject to clinical in the influence of changeable situation, limit it and promote the use of.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of blood collector that patient blood is had better vacuum suction, froth breaking, filtration, recovery effect, project organization compactness at existing background technology.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: this blood collector comprises blood inlet, blood outlet, vacuum suction socket, storage blood bucket, filtering mesh bag, the filtering mesh bag top communicates with blood inlet by blood channel in the storage blood bucket, storage blood bucket top is provided with the vacuum suction socket, blood outlet is arranged at the bottom, it is characterized in that in the described filtering mesh bag bearing support being arranged, the bearing support outside is surrounded by the froth breaking sponge.

Above-mentioned storage blood drum head portion is inclination shape, and the bottom is provided with supporting base, supports a circular housings, has the hole on the carriage; Blood inlet is the joint of a plurality of different-diameters, and horizontally is fan-like pattern, and storage blood bucket has storage blood bung, and it is connected for being threaded or patching with staving; Be directed upwardly circular groove above the storage blood bung, be halved together with the circular periphery bottom of baffle liner, blood channel, its reverse side circular protrusions surface socket-connects with drainage screen bearing support top circle.

This blood collector has following distinguishing feature: 1. the storage blood bucket that combines bottom design conical staving and the inclination shape, and shaped design like this, under same material, equal height prerequisite, volume is bigger, can significantly increase the storage blood volume; The bottom that tilts shape simultaneously, help blood from around concentrate rapidly to the bottom and to flow, can not cause in the stop at a certain position and condense.2. design many specifications, multiduty four groups of blood inlets, diameter is from little extremely big, all design certain conicity, can patch the blood transfusion tube of internal diameter 4～10mm different size, the connection needs that adapt to multitube diameter specifications pipeline, the medical apparatus and the equipment that also can connect four kinds of different purposes simultaneously, be convenient to all types of severely injured patients is in time implemented to rescue and treatment, of many uses, four groups of blood inlets are fan-like pattern and arrange, equate that with the radius of central point spacing distance equates, collision phenomenon when preventing that blood transfusion tube from patching.Simultaneously, four groups of blood inlets and vacuum suction socket are symmetric shape, can bring into play the effect of vacuum suction to greatest extent.3. designed circular housings, hold filtering mesh bag and froth breaking sponge, make filtering mesh bag be unlikely to drop because of the gravity and the impulse force of blood flow, while is in the centre of blood inlet and blood outlet, made a buffered ladder, play the effect of shortening blood drop height in fact, help reducing the blood cell cell and sweep away the damage that is caused from eminence, positive role is arranged, circular housings is provided with diffluence pass, blood after froth breaking is filtered can spill out from the filtering mesh bag bottom along storage blood bucket, prevents the stop of blood and condenses.

The specific embodiment

Embodiment describes in further detail this utility model below in conjunction with accompanying drawing.

As shown in the figure, four blood inlets 1 that level is the employing different-diameter joint of fan-like pattern arrangement connect blood channel 13, rectilinear baffle liner 2, on storage blood bung 5, vacuum suction socket 4 is housed, there is the circular groove 3 that is directed upwardly at position near the center above the storage blood bung 5, be halved together with the circular periphery bottom of baffle liner 2, blood channel 13, the following of it socket-connects near the surface, projection 14 positions at center and the bearing support 6 top circles of filtering mesh bag.The periphery of storage blood bung 5 has circle direction groove down, plug with the staving 15 top periphery projecting member of storage blood bucket, bearing support 6 outsides are from outside to inside being surrounded by filtering mesh bag 11 and froth breaking sponge 7, and they are play supporting role, the outstanding position at the edge of the top circle of bearing support 6, leave fixed position for again filtering mesh bag 11, storage blood bucket 12 bottoms are provided with circular housings supporting base 10, be used for fixing circular housings 8, circular housings 8 is held the bottom of filtering mesh bag 11 and froth breaking sponge 7, simultaneously have diffluence pass on its bottom, the inclination shape bottom of storage blood bucket 12 is provided with the blood outlet 9 of blood after the filtration.

In surgical operation, when the doctor carries out blood attraction and recovery to surgical patient, earlier the negative pressure suction device in the operating room is opened, the vacuum suction pipe is received above the vacuum suction socket, then patient's blood transfusion tube that is used for the blood recovery is on one's body inserted the blood inlet of blood collector, the blood of make attraction, retrieving along the baffle liner wall, slide into blood channel, flow in the filtering mesh bag.Blood is earlier through the froth breaking sponge, foam in the blood is cleared up rapidly, pass through filtering mesh bag again, make the small embolus filtering in the blood, then, blood around filtering mesh bag and the diffluence pass of circular housings flow out, the flow speed and direction blood outlet soon along the round tank wall of storage blood bucket and inclination shape bottom is failed back in the patient body at last again.
