Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to Fig. 1-3, in the utility model embodiment, a kind of accurate anti-clogging with filter screen Quick dredging function Two nozzles of blood transfusion apparatus, including Y-tubes 1, the top of the Y-tubes 1 are separately connected blood bag puncture needle 2 and bag of saline is worn Pricker 3, blood bag puncture needle 2 are connected in blood bag for puncturing blood bag, and bag of saline puncture needle 3 is for being punctured in bag of saline；Y type One nozzle of the lower section of pipeline 1 is connected to the top inlet of quantitative dividing device 4, and the outlet at bottom of quantitative dividing device 4 passes through pipe The import at 5 top of road connection drop pot, the outlet for dripping 5 bottom of pot connects Rapid screwed nipple 6 by pipeline；The inside of drop pot 5 is set There is a filter screen 7, filter screen 7 is fixed on the inner wall of drop pot 5, and middle part is equipped with upward protrusion, and the lower end for dripping pot has one A bubble interlayer 8, for the shape of bubble interlayer in cone shape of tail, the upper end for dripping pot is equipped with the ballonet 9 being connected.

Further, the filter screen is that inverted V type structure is divide into upper part and lower part pot is dripped.

Further, the bubble sandwich design of internal airbag replacement drop pot lower end, the filter screen are elastic filter screen, bullet Property filter screen in the middle part of be equipped with and be respectively placed in the interconnected internal airbag in its both ends: upper end air bag 11 and lower end air bag 12, Upper end air bag 11 is connected with lower end air bag 12 by being connected to hose 13, and lower end air bag 12 is greater than upper end air bag 11.

Further, flow controller is equipped in the Liang Ge branch of the top of Y-tubes 1.

Further, it drips the pipeline between pot 5 and Rapid screwed nipple 6 and is equipped with automatic liquid-stopping folder 10.Pipeline can be saved The liquid level of interior certain altitude.

Further, Rapid screwed nipple 6 is equipped with internal screw thread.Safety can be used when big blood loss, rescue and operation need Needleless linking, bolus injection blood product is conducive to rescue, meanwhile, safe needleless linking can reduce medical staff because of blood transfusion Bring occupational exposure risk.

Further, the position that the flushing-back filtering net 7 in pot 5 is located at lower 1/3 height in inside drop pot 5 is dripped, filter screen 7 A high position can reduce plasminogen accumulation in filtering sieve bottom blood, conducive to the unimpeded of clinical blood transfusion, especially in winter, hang Plasminogen accumulation easy to form in floating red blood cell, be unfavorable for transfusing blood goes on smoothly, and the design energy of the utility model It is enough effectively to avoid this phenomenon.

Further, the lateral wall of quantitative dividing device 4 is equipped with graduation mark, 50ml capacity (using 2ml as unit scale).This is fixed It measures dispenser 4 and uses polyester fiber material, material is conducive to transfusion safety, while this design is able to satisfy the clinical need accurately transfused blood It wants, especially quantitatively transfuses blood newborn, infant, cardiopulmonary insufficiency and disease in the blood system infant and play the work of accurate blood volume With.

The design feature and its working principle of the utility model: advantage one, the utility model designs Y-tubes 1 can be by blood Liquid product is synchronous with physiological saline to be connected, and pollution is reduced, and the quantitative dividing device 4 that Y-tubes 1 are connected to is able to satisfy clinical accurate blood transfusion Needs, especially quantitatively transfuse blood newborn, infant, cardiopulmonary insufficiency and disease in the blood system infant and play accurate blood volume Effect.

Advantage two can reduce plasminogen in filtering sieve bottom blood by improving drop 5 filtering net of pot displacement Accumulation, conducive to the unimpeded of clinical blood transfusion, especially in winter, plasminogen accumulation easy to form in Red Blood Cells Suspension, no Conducive to going on smoothly for blood transfusion.

Advantage three, blood transfusion apparatus scalp acupuncture joining place are designed using spiral hat shape, and pipeline forms screw socket with scalp acupuncture and is connected, head Sword-shaped needle is not easy to slide;Safe needleless can be used when big blood loss, rescue and operation need to be connected, bolus injection blood product, Conducive to rescue, meanwhile, safe needleless linking can reduce medical staff because of bring occupational exposure risk of transfusing blood.

Advantage four can press bubble interlayer with quick-moving speed, at this time when needing to carry out Quick dredging operation to filter screen Due to the shape design directed downwardly of the cone tail of bubble interlayer, so that the blood of drop pot inner lower point is made by the extruding of bubble interlayer With to flow up, so that acting in opposition is in filter screen, and the quick recoil effect of realization, be under pressure upward power, pressure The air of contracting drop pot internal upper part, at this time on partial air not enter in ballonet and collect, will not influence top blood transfusion tube Normal effect, is realized using the recoil to filter screen and is rinsed, the blood constituent of easy accumulation is re-mixed, and realizes Quick dredging The function of filter screen, it is convenient and effective to operate, and also will not influence blood transfusion effect.

Advantage five, the another way of the utility model: can be when needing to carry out Quick dredging operation to filter screen, fastly The bottom of speed pressing drop pot, to squeeze the lower end air bag of internal airbag, lower end air bag is squeezed, and internal gas passes through connection Hose is transmitted to upper end air bag, since filter screen is resilient material, the transmission process of gas can act on filter screen and be formed One gas pulses effect from the bottom to top is put after gas is pressed into upper end air bag so that filter screen generates corresponding vibration Hand, lower end air bag lose squeezing action power, and gas is by flowing back to lower end air bag from upper end air bag, and during which gas is worn again by hose Filter screen is crossed, acts on filter screen again, shock effect is realized to it, it is heavy on filter screen can be effectively deposited in this way Product blood constituent vibration is floated, and realizes the Quick dredging operation of filter screen, effect of the extrusion process to pressure in drop pot, Ke Yitong The gas and ballonet crossed above drop pot are balanced effect, and pressing operation will not influence blood transfusion effect.
