Abstract

The utility model relates to an autoblood recovery feedback bag, composed of a hard casing cover (1), a soft body bag (2), a filtering net (3), a connection port (4), a sealing piston (5), and an input interface (6), which are all made of medical macromolecular material. The integrated process of recovering, filtration, storage, and feedback of autoblood can be completed under the cooperation of a two-way suction device. Other containers do not need to change in the entire process. The collapse and the hemolysis of corpuscle can be avoided. When the utility model is used in emergency treatment, the utility model has the advantages of the time saving is effective, the blood source can be saved, the pollution can be reduced, and the early rehabilitation can be promoted. The utility model is suitable for emergency operations for the patients with extrauterine pregnancy, damage of traumatic livers, spleens, kidneys, hearts, lungs, and aorta rupture and hemorrhage.

Description

Reclaim the feedback bag from body blood

This utility model: reclaim the feedback bag from body blood, belong to medical device, clinical medicine, surgical operation blood recovery field.

Along with the continuous development of modern surgery operation, blood using amount grows with each passing day.But, in surgical intervention, usually running into ectopic pregnancy, liver,spleen,kidney breaks due to the wound, the heart, lung stab, and angiorrhexis massive hemorrhage shock is badly in need of the patient who rescues.The waste of urgent, patient self blood resource of the shortage in blood source, time, problem such as a series of complication that the allosome blood transfusion may cause, the quality of patients ' recovery, financial burden moment presents.In order to resolve above problem, reach in time, effectively rescue, hemorrhage critical patient is pulled through as soon as possible, the purpose of early recovery is utilized two-way principle of negative pressure to design from body blood and is reclaimed the feedback bag.From body blood reclaim to feed back bag combine with two-way negtive-pressure implement form collect recoverys, filter, store, be input as one from body blood recovery feedback device.

Traditional reclaims from body blood, the simple and easy multilamellar filtered through gauze of many employings, the method that vial reclaims, the method anthropic factor is many, enter blood as the gauze fiber, vial and connection tube thereof are cleaning dirty, the formation of pyrogen, and main is that unidirectional vacuum suction impulse force is big, easily cause blood cell to break, cause hemolytic reaction.The home and abroad scholar is exploring for addressing these problems hardy.Look into newly through special topic, at present, technical magazine does not also have identical report, the domestic patent of being found both at home and abroad:

1. hit recording mechanism 1: inhale defeated device notification number from body blood: 2264001

2. hit recording mechanism 2: medicinal blood reclaims the back-transfusion device notification number: 2265810

3. hit recording mechanism 3: autoblood recover notification number: 2274957

4. hit recording mechanism 4: reclaim the back-transfusion device notification number from blood: 2315958 there were significant differences with this utility model on structure, principle.

The purpose of this utility model: providing a kind of from body blood recovery feedback bag is a kind of simple to operate, quick, the practicability and effectiveness of using when rescuing the massive hemorrhage patient, collection reclaims, filters, stores, is input as one, that saves blood resource reclaims a kind of novelty that feeds back from body blood, practical novel medical device.

The purpose of this utility model realizes by following structure and method:

This utility model: reclaim to feed back bag from body blood, by duricrust lid (1), software bag (2), drainage screen (3), connector (4), seal piston (5), input interface (6), link (11) and form jointly, all make with medical macromolecular materials.It is characterized in that: the outer ledge of duricrust lid (1) has the link (11) that uses for hanging, the lower edge and tight-lipped closely connected the closing of software bag (2) inner frieze of duricrust lid (1), and forming an end has the duricrust lid, and the other end is the membranaceous closure capsule bag of software.Duricrust lid (1) and software bag (2) all have support fixation or storage purposes respectively.Connector (4) makes closure capsule bag chamber communicate with outside air, in use be beneficial to other tube chamber and be connected (as suction catheter, interior negative pressure pipe), connector (4) is furnished with and seals piston (5) accordingly, seals piston (5) closure capsule capable of blocking bag chamber and communicates with outside air.Drainage screen (3) is positioned at closure capsule bag intracavity, is fixed on connector (4) on the tubular body that closure capsule bag intracavity extends.Input interface (6) used for when blood transfusion, had the bivalve film in the interface tube chamber, rose and isolated sealing and supporting role.

During use, treated (through the sterilization, reclaiming from body blood the filling anticoagulant) feeds back bag, be placed in the outer vase of two-way negative pressure suction device, plug connection tube, start negative pressure device, because the effect of outer negative pressure, the outer vase of two-way negative pressure device and between body blood reclaiming bag, form negative pressure, the outward expansion force that this negative pressure produces makes from body blood recovery feedback bag unfolds expansion by curling the change, under the effect of interior negative pressure, and the suction pipe of blood process connection, drainage screen reclaims and preserves in the capsule bag, filtered in the bag from body blood, through the bag input interface at the end, tube for transfusion is imported back in the patient's blood vessel again.In the recovery of body blood, filtration, storage, need the auxiliary of two negative pressure suction devices, but feed back in the integrated process finishing, do not need to change other container, avoided the pollution section that break haemolysis and the operating process of blood cell may occur effectively and save time effectively.

The utility model is described in further detail below with reference to accompanying drawing:
