Abstract
The utility model relates to a recovery and infusion device for patient oneself blood, and is used for recycling the blood of the patient, and the blood flows out in an operation and back transporting to the patient; the utility model is composed of a blood collecting bottle, a four way valve which is a whole with a bottle cover, a blood absorbing tube, a tube joint used for connecting an aspirator, a filter arranged on a bottle opening of the blood collecting bottle when the blood is transported back, an insert tube traversing the bottle bottom of an air needle, a blood transfusion needle which is installed on the filter and used for transporting the blood back and a soft tube. The utility model can reduce or avoid the transportation of the xenogenous blood so as to avoid or reduce the complication caused by the transportation of the xenogenous blood, can reduce the dilapidation of the erythrocyte, can reduce the medical cost of patient, can effectively solve the problem of blood source tension, and has convenient use.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly a kind ofly is used for collecting the effusive blood of patient's operation and feeds back to what disease was gone into again and reclaim back-transfusion device from blood.
In the prior art, it is conspicuous losing blood in the operation, all must fail the life that allosome blood gives emergency treatment to a patient under many situations.Patient's feedback from blood in operation also only limits to rupture of spleen at present, and the recovery that intraperitoneal such as ectopic pregnancy are assembled blood feeds back.The method that reclaims is with similar appliances such as bowl or spoons hematocele to be scooped out, and feeds back to go into to disease through after the filtered through gauze.Do not reclaim the utensil that feeds back because of being exclusively used in from blood, it is very low therefore to reclaim the feedback rate, also pollutes easily in the operation.Can't reclaim for the hemorrhage of position, non-abdominal cavity such as spinal column, extremity, brain are outer.Also there is following point in defeated allosome blood:
The one, still be the problem that all has inadequate blood source abroad at home.
The 2nd, because of incubation period and other technical reason of omission and disease infects multiple infectious disease.
The 3rd, multiple complications also can take place in defeated allosome blood, as anaphylaxis etc.
The 4th, increased medical expense to patient.
The purpose of this utility model provides a kind of patient's of being used for operation and reclaims the apparatus that feeds back from blood.
This utility model is realized by following structure.
It comprises the collection blood bottle of the transparent body of collecting blood, bottle cap, with bottle cap constitute integrally-built by blood flow channel, blood flow pass, gas flow channel, gas flow pass valve body and the symmetry that has of switching liquid flow direction switch the cross valve that the spool of groove becomes integral body with spool knob constitutes.The exit of the gas flow pass of valve body has with valve body and becomes the integrally-built pipe joint that is connected suction pump, the porch of blood flow channel has with valve body and becomes the integrally-built pipe joint that is connected blood sampling pipet, and the exit of blood flow pass has and becomes integrally-built row's blood vessel with valve body., there is being used to puncture and inserting the short tube of air inlet needle to the inner of bottle sunken inside sealing at the bottle end of collection blood bottle.Wait to collect blood collection in the blood bottle full after, back out and the integrant bottle cap of cross valve, load onto filter at bottleneck and be inverted to hang and feed back blood.Its filter is by the bottle cap that has female thread, with the integrant funnel of bottle cap, be contained in thick, the thin two-layer drainage screen in the bottle cap, the cage ring that separates two-layer drainage screen is pressed in the sealing ring on the drainage screen of upper strata, and the syringe needle that has blood transfusion tube that inserts funnel top Guan Jian constitutes.The air inlet needle that penetration port is arranged in the bottle end depression short tube of its collection blood bottle during blood transfusion.
Instructions for use, advantage and effect
The spool of rotary four-way valve at first when reclaiming blood, make the switching groove on the spool that the blood flow channel is communicated with the blood flow pass, the gas flow channel communicates with gas or liquid flow pass, connect the suction pump pipeline, start suction pump, gas in the collection blood bottle is drawn out of and produces negative pressure, the suction inlet of blood sampling pipet is placed on the operative hemorrhage position, blood just is inhaled into blood sampling pipet, the cross valve of flowing through is collected in the collection blood bottle, wait to collect in the blood bottle the full back of collection or reclaim finish after, bottle cap unloaded with the filter that is about to feed back blood be tightened on the bottleneck of collection blood bottle, reversal of the natural order of things is on drip stand, and air inlet needle is inserted in puncture in the pore of the depression short tube at the bottle end, the bottle inner blood feeds back blood to patient through blood transfusion needle just by behind the two-layer drainage screen.For a long time hemorrhage in the operation process, reclaim with above-mentioned, give patient according to above-mentioned requirements with blood recovery too after the recovery, during flushing liquor in the sucking-off operation back, only need spool is turned clockwise 90 °, the blood flow channel is communicated with the gas flow pass, and the flushing liquor in the operation just is sucked out, and reaches the purpose of a tractor serves several purposes.
Use during operation from blood recovery back-transfusion device and can make the defeated less or defeated allosome blood of patient effectively.The one, can reduce patient's medical expense; The 2nd, can avoid the complication that takes place because of defeated allosome blood and avoid propagating infectious disease; The 3rd, owing to can give patient with the blood recovery that reclaims at short notice, greatly reduce erythrocytic breakage rate; The 4th, can solve the problem of inadequate blood source effectively.
