Abstract
The utility model belongs to the technical field of medical appliances, which is a self blood retrieving unit comprising a vacuum portion, a blood purifying and absorbing portion and a storing and transfusing portion. The lost blood of the human body can be absorbed, purified, deposited and then re-transfused into the body under the function of vacuum negative pressure, the cross infection caused by the blood transfusion from different bodies is avoided, and the insufficiency state of the blood source is released. The self blood retrieving unit has more important meaning for the field rescue of the surgical operation of field operations.
Description
This utility model relates to medical apparatus and instruments.
In clinical treatment work, often run into massive hemorrhage, the traffic accident in the patient operation and other traumatic internal organs break and the massive hemorrhage of gynecological's ectopic pregnancy or the like, these blood of past are all fallen seldom to utilize by drain, and posthemorrhagic patient is badly in need of enriching blood and must be carried out allosome blood transfusion, so the danger of cross infection is just inevitable.Besides as run into the blood source when nervous, military first aid particularly, the preciousness of blood well imagines that the life that often is related to a people is with dead.
The purpose of this utility model is exactly the waste that causes at the blood of present loss and design the blood that can make loss and carry out the self-blood recover that utilizes again after the purified treatment.
Embodiment of the present utility model is such: the design of self-blood recover is to utilize the vacuum principle to make to produce in the sealed container negative pressure that the blood absorption that runs off is purified natural sedimentation to store and re-enter in the human body body.It is made up of the vacuum section that produces vacuum, negative pressure, blood purification absorption portion and storage importation.
Self-blood recover according to this utility model design, can make the blood of original loss used for the he or she again, the cross infection of having avoided patient to cause because of the allosome blood transfusion, stopped acquired immune deficiency syndrome (AIDS), the infection of diseases such as hepatitis B, also alleviated blood source tense situation, and saved medical expense for patient, the patient of a rupture of spleen for example, minimum amount of bleeding is more than 2500 milliliters, as utilize the design's recover, by the response rate 70%, per 100 milliliters of 30 yuan of meters of blood valency can be patient and save nearly 600 yuan, concerning aseptic sursery, have more immeasurable economic benefit and social benefit.
Fig. 1 is a structural representation of the present utility model.
Below be described in detail at accompanying drawing embodiment.
With reference to Fig. 1: the self-blood recover is by producing negative pressure of vacuum and can regulating the vacuum section of negative-pressure balancing, disposable purification absorption portion and store the importation and form.
Vacuum section comprises vacuum pump (5) and negative pressure bottle (6), vacuum pump (5) is the power source of this recover, negative pressure bottle (6) is round ampuliform, plastics are made, two root rubber pipes (4), (3) on the rubber stopper of bottle top link to each other with reservoir (7) with vacuum pump (5) respectively and communicate, and the effect of negative pressure bottle (6) is conduction negative pressure, adjusting negative-pressure balancing.
The plastic tube (2) that purifies absorption portion plays the purification and the Absorption of blood, under negative pressure, make the intravital blood of people be equipped with by the end that 400 purpose filter membranes (1) and afterbody are equipped with that 200 purpose bag shape filter membranes (8) filter blood and self-purification and the further precipitation of input reservoir (7) continuously, because this part directly contacts with blood, the disposable use of historical facts or anecdotes row.
Storing the importation is made up of reservoir (7) and blood bag (11) that downside has silica gel plug (9), the round ampuliform of reservoir (7), about 3000 milliliters of volumes, plastics are made, can bear pressure 3.5-4Kg, work the plastic tube (2) that purifies Absorption and stretch in the reservoir (7), and have rubber tube (3) to be connected, in order to the conduction negative pressure with negative pressure bottle (6) by the sealing rubber plug above the bottleneck.Reservoir (7) bottle is marked with scale, the storage capacity of record blood.In reservoir (7) downside silica gel plug (9) and the pipeline that blood bag (11) is connected actuator (10) is housed, it had not only played on-off action but also had played the regulating action of velocity of blood flow, make aseptic blood input blood bag (11) by puncture needle, connect the blood exchange transfusion set and can import human body, this part also is disposable use.
In order to prevent blood coagulation, 100 milliliters of blood of every drain need inject 10 milliliters of anticoagulant in reservoir, are added by puncture on the silica gel plug of reservoir downside, and anticoagulant adopts sodium citrate or heparin solution.
Disposable use part-structure all after cyclohexane sterilization by plastic bag packaging, storage life is a year and a half.
The used rubber tube of the design, plastic tube, bottle, silica gel plug or the like are medical material and make.Each matching part needs strict seal.
Claims (4)
1, a kind of self-blood recover is characterized in that this recover comprises that the vacuum section that produces negative pressure of vacuum, the purification absorption portion of carrying out the blood purification absorption and storage importation are formed by connecting by connecting pipe is sealed to each other.
2, self-blood recover as claimed in claim 1 is characterized in that described vacuum section is made up of vacuum pump (5) and negative pressure bottle (6), and with rubber tube (4) one that links to each other.
3, self-blood recover as claimed in claim 1 is characterized in that described purification absorption portion is made up of the plastic tube (2) that two ends have filter membrane (1), (8), and an end that wherein has filter membrane (8) stretches into to be stored in the importation.
4, as claim 1 or 3 described self-blood recovers, it is characterized in that described storage importation is made up of reservoir that has silica gel plug (9) (7) and blood bag (11), in the connecting pipe of reservoir (7) and blood bag (11) actuator (10) is housed, links to each other with the negative pressure bottle (6) of vacuum section by rubber tube (3) on the rubber stopper of reservoir (7) top.
