Abstract
The utility model discloses a disposable hangless transfusion system. The utility model has a pressurized cylinder utilized for extruding the soft liquor bottle, and the soft liquor bottle is arranged in the pressurized cylinder, the sealing surface is communicated with a flow equalization pressure valve through a catheter, the flow equalization pressure valve is communicated with the flow rate conditioner and the syringe needle orderly through the catheter. Aiming to ensure the flow rate of the liquor truly, a flow-meter can be connected in the injector. By adopting the transfusion system, put the soft liquor bottle (such as the liquor bottle of plastic bag-type and the liquor bottle of soft wood corner-type) into the pressurized cylinder, when the soft liquor bottle receives the extrusion, the liquor flows into the flow equalization pressure valve through the sealing face, and the liquor flows through the flow rate conditioner and the syringe needle. Because the power of outleting the liquid is the pressure of the pressurized cylinder, the liquor bottle needs not hanging in the high place.
Description
Technical field
This utility model relates to a kind of transfusion device.
Background technology
Existing transfusion device structure is very simple, and during use, an end inserts in the medicinal liquid bottle, and an other end inserts in the patient's blood vessel, and the medicinal liquid product are suspended on eminence, infuses by the gravity of liquid, and controls the flow of medicinal liquid by a flow controller.Some transfusion devices like this, because general transfusion time is longer, patient can only lie or sit in bed and can not walk about, and uses extremely inconvenient.
Summary of the invention
This utility model provides a kind of disposable transfusion device of exempting to hang, and this transfusion device need not a medicinal liquid bottle and hangs on eminence when transfusion.
Described in the utility modelly disposablely exempt to hang transfusion device one pressure measuring cylinder that is used to push soft medicinal liquid bottle is arranged, soft medicinal liquid bottle places pressure measuring cylinder, its bottleneck is communicated with the current-sharing pressure valve by a conduit, and the current-sharing pressure valve is communicated with flow regulator and injection needle successively by conduit.
In order to determine in above-mentioned syringe, can to insert an effusion meter by medicinal liquid flow accurately.
Adopt transfusion device described in the utility model, soft medicinal liquid bottle, for example plastics pocket type medicinal liquid bottle, cork angie type medicinal liquid bottle are placed in the pressure measuring cylinder, in pressure, receive extruding, medicinal liquid just can flow into the current-sharing pressure valve from bottleneck, make the flow stream pressure equilibrium after, flow through flow regulator and injection needle, owing to adopt the power of the pressure of recipient, and no longer need the medicinal liquid bottle is hung on eminence as transfusion.
Description of drawings
Fig. 1 is the structural representation of transfusion device described in the utility model;
Fig. 2 is the structural representation of described pressure measuring cylinder;
Fig. 3 is the structural representation of soft medicinal liquid bottle;
Fig. 4 is the structural representation of current-sharing pressure valve.
The specific embodiment
As shown in Figure 1, describedly disposablely exempt to hang transfusion device one pressure measuring cylinder 1 that is used to push soft medicinal liquid bottle is arranged, soft medicinal liquid bottle 2 places pressure measuring cylinder 1, and its bottleneck is communicated with current-sharing pressure valve 3 by a conduit, and current-sharing pressure valve 3 is communicated with flow regulator 4, effusion meter 5 and injection needle 6 successively by conduit.
As shown in Figure 2, pressure measuring cylinder is the urceolus tube 1a and the inner core 1b of two mutual back-offs, and urceolus and inner core all adopt transparent material to make, and a stage clip 1c is arranged in pressure measuring cylinder.
Be illustrated in figure 3 as the infusion bottle 2 of a cork angie type.Infusion bottle 2 is placed in the urceolus 1a of pressure measuring cylinder 1, and stage clip 1c is pushed down in its underpart, and inner core 1b back-off is gone in the urceolus, and blocks the barrel of inner/outer tube with card post 1d; The bottleneck of infusion bottle 2 protrudes from the top of urceolus.Said structure makes transfusion tube 1 be subjected to the compressing of stage clip and don't can eject from pressure measuring cylinder.
Be illustrated in figure 4 as the structural representation of current-sharing pressure valve 3.It comprises a both ends open body 3a, and the two ends of body 3a are respectively into head piece 3b and go out head piece 3d; Going into head piece 3b upward has a blood return prevention valve 3c in the top, at body 3a internal fixation one filter 3e is arranged, and is a bowl-shape promotion bowl 3f under the filter, seals the inner separated into two parts of body by cushion rubber 3g between its outer wall and the body inwall; Promote lower part of bowl and be pressed with spring 3j, blood return prevention valve 3c fuses with the promotion bowl by the connecting rod 3h that passes filter 3e; The bottom that promotes bowl is equipped with a hollow pipe 3i, hollow pipe 3i is also in aggregates in promoting bowl, and the side on hollow pipe 3i top has an inlet 3k, and lower side has an outlet 3m, and an accent stream bar 3n has been inserted in the lower end of hollow pipe, transfers the stream bar to be fixed on the body bottom.
The extruding of tube because infusion bottle is stressed and medicinal liquid extruding is gone into head piece 3b as for current-sharing valve 3, the pressure of the liquid stream of this moment is anisobaric, after medicinal liquid is pushed blood return prevention valve 3c open, filter pusher dynamic pressure bowl through filter 3e, compression spring 3j, medicinal liquid flows into hollow pipe from the lateral inlet 3k of hollow pipe 3i, and flows out to the body bottom from its outlet 3m, flows into out head piece 3d from flow-out hole 3p at last.When flowing into the flow stream pressure of current-sharing valve 3 when big from going into head piece, the pressure that the pressure bowl is subjected to is also bigger, thereby cause the compression degree of spring 3j to strengthen, hollow pipe also just moves down with promoting bowl, the degree of transferring stream bar 3n to insert hollow pipe increases, the outlet that part is stopped up hollow pipe reduces the space of outlet 3m, and flow quantity also just reduces thereupon; When from going into flow stream pressure that head piece flows into current-sharing valve 3 hour, then in contrast.Thereby can keep out all amounts output of medicinal liquid flow.
