Technical field
The present invention relates to a kind of medical infusion method and apparatus, especially provide squeezing effect to apply pressure to transfusion bag by the compression spring and realize infusion process, be applicable to field hospital or transport wounded's process medium because the situation that condition is limited transfusion bag can not be hung up the time at simple and easy stretcher.
Background technology
At present, when generally in hospital, infusing, all be that transfusion bag or infusion bottle are hung on the drip stand, can utilize the gravity of medicinal liquid itself and atmospheric effect that liquid is flowed in the body smoothly like this.But in some special occasion, basic medical condition and facility are difficult to satisfy, and for example the field hospital on battlefield next door, possibility such as stretcher of transporting the wounded provide drip stand surely owing to condition restriction differs, and have brought difficulty to normal infusion thus.
The action of gravity that produces except the suspension mechanism that utilizes drip stand realizes the transfusion, can also utilize action of mechanical pressure to produce required hydraulic pressure and reach the purpose of exempting to hang transfusion in the plastic infusion bag with deformable mechanism.Can not only effectively solve the drawback in the traditional infusion process like this, and open up a new route for modern infusion techn.
On the one hand, when patient wants to leave the bed when walking about, do not need infusion bottle is held high, get final product and only need carry this device box, this is quite easily; Pressurizing unit box bottom can reserve a mechanism of wearing belt or strap, so that tie up on patient's belt or on the stretcher handle.
On the other hand, after transfusion is finished,, can not cause the backflow of blood problem even without in time pulling out pin yet, like this, the rest that patient just can feel at ease in infusion process.
Summary of the invention
Technical problem: traditional infusion needs infusion bottle or transfusion bag are hung, and utilizes the gravity of medicinal liquid itself and atmospheric effect messenger drug liquid stream to go into human body.And extrusion pressing type infusion method proposed by the invention and device will overcome this problem exactly, to adapt to some special occasions owing to also can finish the normal infusion process under the limited situation that drip stand can not be provided of conditioned disjunction equipment.
Technical scheme: extrusion pressing type transfusion device of the present invention is made of the box body that a top has movable upper cover plate, both sides in the upper shed of box body are respectively equipped with a baffle plate, in box body, the bottom of baffle plate is provided with an inner hard portable plate, between hard portable plate in inside and box body inner bottom part, be provided with the compression spring, be respectively equipped with a upper cover plate groove in the both sides of movable upper cover plate, this upper cover plate groove and baffle plate match, and the both sides outside box body are respectively equipped with a snap close.When the compression spring was one, the compression spring was positioned at the middle part of box body; When the compression spring was many, the compression spring was distributed in the box body.
Be noted that tube for transfusion that this device adopts insert that end of transfusion bag only single hole be used for medicinal fluid output, do not have tradition to hang the extra air inlet design that transfusion is adopted.
As mentioned above, this device mainly is to be made of the box body of a front openings and some compression springs.The range of activity that two baffle plates have limited hard portable plate about box body top makes it can not eject the box body.With movable upper cover plate lid down, and upper cover plate is buckled next with the snap close on box body both sides, then the groove part of upper cover plate and two baffle plates fit, the part (projection thickness is greater than baffle plate thickness) that upper cover plate protrudes then promotes hard portable plate and moves down, and the spring that just is in compressive state is originally compressed more.
The transfusion bag bag mouth that inserts tube for transfusion is placed up, and then the air suspension in the transfusion bag is pushed transfusion bag in the liquid level top with hands, and gas in the bag is discharged.The device for opening upper cover plate is placed on the transfusion bag bag mouth outwardly on the hard portable plate, covers upper cover plate, buckles snap close again, because transfusion bag has certain thickness, promoting hard portable plate, to move down quantitative change big, and the decrement of spring increases when not adding transfusion bag.At this moment, transfusion bag is under the cooperation extruding of hard portable plate and movable upper cover plate, and liquid hydraulic pressure increases in the bag.So, under this hydraulic effect, the transfusion beginning.In the infusion process, the gear of flow speed controller can reach the purpose of control flow velocity on the slip tube for transfusion.
Beneficial effect: this method and apparatus is realized exempting to hang the function of transfusion, and will in time pull out syringe needle after effectively solving traditional infusion and finishing, otherwise the problem that blood can flow backwards.Because along with the outflow of medicinal liquid, amount of spring compression reduces, the pressure that transfusion bag is subjected to also reduces, and the hydraulic pressure of liquid reduces in the bag.When liquid hydraulic pressure and blood pressure balanced each other, liquid that can not flowed into blood vessel again in the transfusion bag, and blood can not dash yet, and transfusion is finished.So this device untimely pin that pulls out after transfusion is finished can not bring injury to the people yet, need not extra interpolation transfusion and finish alarm device.The thickness of reasonably initial amount of spring compression and movable upper cover plate projection can make only surplus a little medicinal liquid in the transfusion bag, does not even remain medicinal liquid, does not therefore influence the normal infusion amount.If patient will leave the bed and walk about, then will transfusion bag not hold high, and only need be with device box to get final product.Because pressurizing unit box bottom has reserved a mechanism of wearing belt or strap, the man also can be through at device box between waist on the belt.Therefore this device another one benefit makes things convenient for patient to leave the bed to walk about exactly.Generally speaking, this method and apparatus principle is simple, and it is convenient to implement, and apparatus cost is low, and volume is little, need not power supply, and can recycle repeatedly.

Fig. 2 is the sketch map of the movable upper cover plate of device when covering.
Have among the figure: movable upper cover plate 1, inner hard portable plate 2, snap close 3, baffle plate 4, upper cover plate groove 5, box body 6, compression spring 7.
The specific embodiment
This installs the inner hard portable plate of main use device box, is subjected to many compression spring impetuses, with movable upper cover plate cooperation extruding transfusion bag, makes the interior medicinal liquid of transfusion bag produce required hydraulic pressure and finishes the transfusion overall process.
Extrusion pressing type transfusion device is made of the box body 6 that a top has movable upper cover plate 1, both sides in the upper shed of box body 6 are respectively equipped with a baffle plate 4, in box body 6, the bottom of baffle plate 4 is provided with a hard portable plate 2 in inside, between hard portable plate 2 in inside and box body 6 inner bottom parts, be provided with compression spring 7, be respectively equipped with a upper cover plate groove 5 in the both sides of movable upper cover plate 1, this upper cover plate groove 5 matches with baffle plate 4, and the both sides outside box body 6 are respectively equipped with a snap close 3.When compression spring 7 was one, compression spring 7 was positioned at the middle part of box body 6; When compression spring 7 was many, compression spring 7 was distributed in the box body 6.
Extrusion pressing type transfusion device, comprise that the ultimate principle of utilizing two plane clamping plate extruding plastic transfusion bag realizes exempting from hanging the basic device of method and this method of realization of transfusion, promptly front openings, above the box of a movable upper cover plate (the box body is with lock to be buckled) is arranged, there is a hard treadmill inside, this flat board is parallel with movable upper cover plate, and realizes that under a plurality of spring supporting roles it and movable upper cover plate cooperation push the effect of transfusion bag.
There is the range of activity of hard portable plate in the baffle plate restraint device box both sides, extruding infusion set box top, in order to avoid eject or the loss of dropping, and movable upper cover plate has the groove design that cooperates two baffle plates, upper cover plate is covered under the situation, the groove lower surface can be fitted with baffle plate, and hard portable plate closely is harmonious with the upper cover plate projection under spring action, thereby guarantees to infuse when finishing, and hard portable plate and upper cover plate also have very big extruding force to transfusion bag.Just there is not residual liquid when transfusion finishes like this in the transfusion bag substantially.Pressurizing unit box body 6 bottoms can reserve a mechanism of wearing belt or strap, so that tie up on patient's belt or on the stretcher handle.
The tube for transfusion that is adopted insert that end of infusion bottle only single hole be used for medicinal fluid output, do not have tradition to hang the extra air inlet design that transfusion is adopted.It is as follows that transfusion bag is put process: the movable upper cover plate of device box is opened, and the transfusion bag bag mouth is flat on the hard portable plate outwardly, covers movable upper cover plate, fixes with snap close.This moment, hard portable plate moved down through the pressure that transfusion bag transmits because of being subjected to upper cover plate, and the spring of its below shrinks.Transfusion bag improves owing to the cooperation extruding that is subjected to upper cover plate and hard portable plate makes bag interior liquid hydraulic pressure, the transfusion beginning, and infusion flow rate can rely on the gear of the flow speed controller on the tube for transfusion to regulate.
For preventing that infusion process from having gas to be squeezed into blood vessel, require to use the transfusion bag of evacuation packing, inside does not have gas, perhaps go forward to carry out earlier emptying gas operation transfusion bag being placed on hard portable plate, specific practice is with the transfusion bag bag mouth up, implements transfusion behind the gas again with hands extruding transfusion bag in having arranged all transfusion bag.
The spring that connects at the bottom of hard portable plate and the box adopts the bigger spring of initial compression amount.This be because in the infusion process transfusion bag thickness reduce cause amount of spring compression to reduce, the hydraulic pressure of liquid reduces in the transfusion bag, thus transfusion speed is slack-off.Adopt the spring of initial compression amount, just can ignore the variation of infusion process medi-spring decrement, thereby make change in flow less, even ignore much larger than transfusion bag thickness.
Along with reducing of transfusion bag thickness, the hydraulic pressure of liquid also reduces in the transfusion bag, and when the hydraulic pressure of liquid and blood pressure balanced each other, transfusion was finished, that is: medicinal fluid no longer flows into blood vessel, and blood can not pour tube for transfusion yet.Certainly, if initial amount of spring compression is enough big, the thickness of perhaps movable upper cover plate projection is enough big, can guarantee that liquid hydraulic pressure is all the time greater than blood pressure in the transfusion bag, and at this moment, the transfusion bag herb liquid can be totally lost to greatest extent.Therefore this device can not only save transfusion and finish alarm device, and can accomplish medicinal liquid is totally lost to greatest extent.
