Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of change-blood bloodletting instrument.
Background technology
Neonatal exchange transfusion therapy is with blood plasma and hemocyte in storehouse blood replacement patient body, is replaced by the pathological product in blood
Out, reach the purpose for the treatment of, be the treatment most effective and the most rapid method of hyperbilirubinemia of newborn, be mainly used in serious symptom
The hemolytic disease of newborn of mother and baby's blood group incompatibility is redemption life, the important measures of sequela are reduced or avoided.This technology starts from
The 1950's, classical change-blood method is that umbilical vein is put pipe single tube alternately pumping and completed change-blood, but because pumping process can not
Synchronization is carried out, thus causes infant blood pressure surging, and then affects the blood supply balance of each internal organs.The most current domestic often adopt
By peripheral artery vein synchronizing design method, i.e. transfuse blood from peripheral vein, draw blood from peripheral arterial simultaneously, but taking out of using at present
Blood mode, blood need to have part residual through apparatuses such as blood drawing pumps, be therefore difficult to accurate measurement blood drawing amount, exist relatively unavoidably
Big medical-risk.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of change-blood bloodletting instrument, energy accurate measurement blood drawing amount, reduces
Medical-risk.
This utility model solves the problems referred to above by techniques below means: a kind of change-blood bloodletting instrument, including remaining needle, blood
Liquid quantifier and asepwirator pump, described remaining needle is connected with blood-pressure meters measuring device top by blood transfusion tube, described blood-pressure meters measuring device table
Face is provided with scale, is provided with through hole bottom blood-pressure meters measuring device, and described through hole is provided with breathing waterproof film, and described asepwirator pump leads to
Cross gas flow tube to connect with through hole.
Further, being provided with collecting tank bottom described blood-pressure meters measuring device, blood-pressure meters measuring device is by leakage mouth with collecting tank even
Logical, it is provided with pressure switch at described leakage mouth, in described collecting tank, is provided with sensor, also include controller and alarm,
Described sensor is electrically connected with the controller, and described alarm also has controller to electrically connect.
Further, protection set it is arranged with outside described remaining needle.
The beneficial effects of the utility model: change-blood bloodletting instrument of the present utility model, including remaining needle, blood-pressure meters measuring device with
And asepwirator pump, described remaining needle is connected with blood-pressure meters measuring device top by blood transfusion tube, and described blood-pressure meters measuring device surface configuration has quarter
Degree, be provided with through hole bottom blood-pressure meters measuring device, described through hole is provided with breathing waterproof film, described asepwirator pump by gas flow tube with
Through hole connects.The change-blood bloodletting instrument of this structure, energy accurate measurement blood drawing amount, greatly reduce medical-risk.
Accompanying drawing explanation
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is described in detail, as shown in Figure 1: a kind of change-blood bloodletting instrument, bag
Including remaining needle 1, blood-pressure meters measuring device 2 and asepwirator pump 3, described remaining needle is connected with blood-pressure meters measuring device top by blood transfusion tube 4, institute
Stating blood-pressure meters measuring device surface configuration and have scale 5, be provided with through hole 6 bottom blood-pressure meters measuring device, described through hole is provided with ventilative anti-
Moisture film 7, described asepwirator pump is connected with through hole by gas flow tube 8, and described remaining needle is neonate shallow table needle of retaining on artery, in indwelling
Being arranged with protection set 15 outside pin, one is to avoid remaining needle syringe needle to hurt sb.'s feelings, and two is to avoid remaining needle to be contaminated, and uses
Time, take off protection and overlap.When carrying out change-blood blood drawing, retained needle puncture enters infant tremulous pulse, is generally selected elbow tremulous pulse, subsequently air-breathing
Pump work, forms negative pressure, thus is extracted out by blood in making blood transfusion tube and blood-pressure meters measuring device, blood flows into blood-pressure meters after blood transfusion tube
Storing in measuring device, blood flow rate is controlled by asepwirator pump, can be the most accurate by the scale being arranged on blood-pressure meters measuring device
Display blood drawing amount.The change-blood bloodletting instrument of this structure, during change-blood blood drawing, blood need not pass through asepwirator pump, it is only necessary to logical
Cross a bit of blood transfusion tube to be i.e. directly entered in blood-pressure meters measuring device and measure, substantially increase the measuring accuracy of blood drawing amount, reduce
Medical-risk.
As the further improvement to technique scheme, bottom described blood-pressure meters measuring device, it is provided with collecting tank 9, blood-pressure meters
Measuring device is connected with collecting tank by leakage mouth 10, is provided with pressure switch 11, is provided with in described collecting tank at described leakage mouth
Sensor 12, also includes controller 13 and alarm 14, and described sensor is electrically connected with the controller, and described alarm also has control
Device electrically connects.When in blood-pressure meters measuring device, blood reaches the capacity set, and the pressure i.e. caused to pressure switch reaches the big of setting
Little, pressure switch is opened, and fraction blood flows in collecting tank, and sensor is humidity sensor, and sensor sensing is wet to blood
Degree, passes to controller by signal, and controller controls alarm equipment alarm, reminds medical personnel to stop blood drawing in time, drops further
Low medical-risk.
Finally illustrating, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although ginseng
According to preferred embodiment, this utility model is described in detail, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent, without deviating from objective and the model of technical solutions of the utility model
Enclosing, it all should be contained in the middle of right of the present utility model.
