Abstract
The utility model relates to a disposable transfusion flow regulator, which is composed of a casing, a damping sleeve which is arranged in the casing, a sealing ring, a rotating core, a turn knob which is connected with the rotating core into integration and connecting nozzles of an inlet and an outlet, wherein the connecting nozzles are respectively connected with a transfusion tube, and an outer circle of the turn knob is designed into a tooth-shaped structure; an arm-shaped collapse-resistant device and a balance block which is symmetrical with the collapse-resistant device are arranged on the casing; the collapse-resistant device is engaged with the turn knob. The utility model has the advantages that the utility model can be engaged with teeth on the periphery of the turn button to play the role of positioning by the arm-shaped collapse-resistant device and the balance block which is symmetrical with the collapse-resistant device; besides, the damping sleeve in the casing can be protected, therefore deformation can not be caused to affect the accuracy of the flow. Because the regulator does not need driving by energy sources, the utility model can be operated simply and used conveniently; therefore, the utility model can widely satisfy the operating requirements in any occasion.
Description
Technical field
This utility model belongs to the Dispoable medical apparatus, particularly relate to a kind of in continuing micro-infusion treatment, can meticulous adjusting fluid flow and need not driven by energy, disposable infusion flow regulator simple to operate, easy to use.
Background technology
Infusion is still clinical main means of administration so far, domestic existing infusion method and supporting for it disposable transfusion device can only satisfy heavy dose of transfusion needs at present, as Drug therapy, heavy dose of transfusion often makes excessive unnecessary moisture inject in the body, and this patient to some disease (as edema patient, nephrotic etc.) can produce very adverse influence undoubtedly.In the modern medicine, the treatment and the Drug therapy that require to continue the trace transfusion day by day increase, so the various medical apparatus and instruments that continues the trace transfusion of serving arises at the historic moment.
Usually, the fluid flow during infusion is to control with the roller type in the disposable transfusion device " water ends ", and this accurately regulates ask for something and the transfusion occasion of trace control medicinal liquid flow velocity can't meet the demands at all.Import nitroglycerin as the patient for the need controlling blood pressure, the Pu Na that disappears during medicines such as erbanin, generally needs the defeated 8-15 of control per minute to drip the speed of (approximately 20-40ml/hour), uses the traditional infusion device to regulate and to observe.Although being arranged, employing " volumetric infusion pump " accurately controls patient's dosage, transfusion speed and amount of infusion, but this apparatus needs power drives, and operation requires high, and price is expensive, so can not be extensive use of, bring certain influence for the treatment technology of promoting lasting trace transfusion.
Summary of the invention
This utility model provides a kind of in continuing micro-infusion treatment for solving the technical problem that exists in the known technology, can meticulous adjusting fluid flow and need not driven by energy, disposable infusion flow regulator simple to operate, easy to use.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
The disposable infusion flow regulator, by shell, in the enclosure damping cover, sealing ring be set, revolve core, form with revolving the knob that core is connected as a single entity and the gateway that is connected tube for transfusion connect to chew, it is characterized in that: the knob cylindrical is designed to tooth-shape structure, and design has arm shape gram to collapse and collapses symmetric balance weight with gram on described shell, and this gram collapses and meshes with knob.
This utility model can also adopt following technical measures:
Tube for transfusion gateway on the described shell connects to chew and is one-line arrangement, and collapses with balance weight with arm shape gram and to be 90 ° of angles.
Design has circle-shaped demonstration to regulate the graduated disc of flow above the described knob.
Advantage and the good effect that the utlity model has are: because this utility model is used for reference the form and the damp type flow-control principle of industrial knob pressure valve, accomplish to realize the purpose of trace adjusting flow.Utilize the arm shape gram on the shell to collapse and symmetric balance weight simultaneously, can play the role of positioning, can guarantee under the little situation of external force, to avoid knob to misroute the moving flow that changes again with the tooth engagement of knob periphery; The effect of balance weight be the internally-damped cover of protection not reason gram collapse the side force that produces with knob and deform so that may influence flow accurately.This product provides a kind of infusion flow adjuster that can meticulous adjusting fluid flow for needing to continue micro-infusion treatment clinically.Because this actuator does not need driven by energy, and is simple to operate and easy to use, therefore can extensively be satisfied with the instructions for use under any occasion.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cut-away view of the present utility model.
Among the figure: 1 knob graduated disc, 2 knobs, 3 arm shapes gram collapse, 4 gateways connect and chew, 5 shells, 6 damping covers, 7 revolve core, 8 sealing rings, 9 balance weights.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the disposable infusion flow regulator, by shell 5, in the enclosure damping cover 6, sealing ring 8 be set, revolve core 7, chew 4 and form with revolving the knob 2 that core is connected as a single entity and connect the gateway that is connected tube for transfusion, the knob cylindrical is designed to tooth-shape structure, design has the arm shape gram that is connected as a single entity with it to collapse 3 and collapse symmetric balance weight 9 with gram on described shell, this arm shape gram collapses with knob and is the engagement shape, described tube for transfusion gateway connects chews 4 and is one-line arrangement, and collapses with balance weight with arm shape gram and to be 90 ° of angles.Design has circle-shaped demonstration to regulate the graduated disc 1 of flow on knob, mark on this graduated disc actuator " pass " (off), scale and " maximum " position (max) between 15 (ml/hour) → 300 (ml/hour).
Operation principle of the present utility model is: at first the gateway of this actuator is connect and chew the two ends up and down that are connected to tube for transfusion, operator's rotary knob 2 in a clockwise direction then collapses three cornet marks on 3 by arm shape gram and controls the size of infusion flow in alignment with the scale on the knob graduated disc or close.
Claims (3)
1. disposable infusion flow regulator, by shell, in the enclosure damping cover be set, revolve core, with revolve knob that core is connected as a single entity and the gateway that is connected tube for transfusion and form by chewing, it is characterized in that: the knob cylindrical is designed to tooth-shape structure, and design has arm shape gram to collapse and collapses symmetric balance weight with gram on described shell, and this gram collapses with knob and meshes.
