Abstract
A medical infusion tube device with a non-return function is based on a structure in the prior art. The medical infusion tube device is characterized in that a flow tube display (3) is included, a floating ball (4) is arranged in the flow tube display (3), the diameter of the floating ball (4) is less than the inside diameter of the flow tube display (3) and greater than the infusion pore diameter at the lower part of the flow tube display (3); the overall process of the using method of the medical infusion tube device is identical with that of the prior art; and in order that the floating ball can finally float on the surface of liquid medicine (P) in the flow tube display (3) arranged vertically, the only differentia in the use of the medical infusion tube device is that the floating ball (4) in the flow tube display (3) is pinched by hands through the soft flow tube display (3), so that the liquid medicine (P) flows through the section parts of plump space formed on two sides of the floating ball (4) by deformation; or the hard flow tube display (3) is hold up by the hands, kept flat and is horizontally and vertically shook, so that the liquid medicine (P) flows through the side clearance of the floating ball (4).
Description
Technical field
The present invention relates to medical infusion dropper technology, especially related to a kind of dropper device that after transfusion finishes, can prevent (tracing back) function that refluxes on the blood of human body.
Background technology
At present, hospital is that the dropper device of patient infusion is after transfusion finishes, if in time do not found by the nurse, to the blood in the patient infusion blood vessel generally can be under the driving of human body internal pressure by penetrating blood vessel syringe needle and reflux (tracing back) to human body external a segment distance or height along tube for transfusion ...
Summary of the invention
The present invention's purpose: be exactly by addressing the above problem a kind of improvement that proposes prior art.---make infusion techn further be improved.
In order to realize the foregoing invention purpose, intend adopting following technology:
The present invention structurally comprises: the infusion needle that is arranged on the tube for transfusion bottom, be arranged on that the flow dropper display on the tube for transfusion---it is produced and can adopt the soft transparent material, for example: " plastics ", perhaps, can adopt hard transparent material, for example: " glass "---and with the placed in-line flow regulator of flow dropper display (belonging to prior art), it is characterized in that: in the middle of above-mentioned flow dropper display, also be provided with its diameter less than this flow dropper display internal diameter and greater than the ball float in transfusion aperture, this flow dropper display bottom, it can adopt light plastic or other light materials on the liquid level that can swim in medicinal liquid to make.
Characteristics of the present invention: improved safe class to patient infusion, promptly reduce the probability of the accident that meets accident, for example: the medicinal liquid in infusion bottle is used the light time, and the liquid ball float in the middle of the flow dropper display will fall the infusion hole of blocking this flow dropper display bottom: guarantee to avoid the blood backflow (tracing back) in the human vas to enter in the middle of the tube for transfusion to leaving blood vessel.Even if---for various reasons (for example: work be extremely busy) and in long-time the nurse do not find or when having little time in time to handle, also be difficult for betiding the disadvantageous unexpected situation of patient; In sum, the present invention finally is: improved the medical safety grade of guaranteeing " perfectly safe " character and created condition in the process of patient being used medical apparatus and instruments.
Description of drawings
Figure has illustrated embodiments of the invention (wherein having adopted soft flow dropper display).
1: infusion bottle; 2: tube for transfusion; 3: flow dropper display; 4: its diameter is between the ball float in flow dropper display internal diameter and transfusion aperture, flow dropper display bottom; 5: flow regulator; 6:: infusion needle; P: medicinal liquid.
The specific embodiment
Key of the present invention is: in the medicinal liquid P when to patient infusion was about to use up, the ball float 4 that is provided with in the infusion set can fall automatically carried out the continuation transfusion of blocking-up to patient.
---critical component of the present invention: flow dropper display 3 can adopt the method that the two is combined into one with them again after the machine-shaping respectively synthetic with the ball float 4 that is arranged on wherein, and should consider to allow ball float 4 fill in from the top hole of flow dropper display 3 this moment; Perhaps, can consider that also the flow dropper display 3 of this moment has just broken away from the ball float 4 that is arranged on wherein never with the ball float 4 of forming formerly the two comparatively complicated and advanced once through moulding technology with 3 molding of flow dropper display.
Using method of the present invention is very simple, and its overall process and prior art are identical, and for ball float 4 finally can be swum on the liquid level of flow dropper display 3 herb liquid P of vertical placement, difference unique when it uses is as follows:
Allow medicinal liquid P flow through one of method of soft flow dropper display 3 (flatten deformation method---more convenient):
Allow staff pinch the ball float 4 that wherein is arranged in flow dropper display 3, can allow medicinal liquid P from the section position, space of deformation tympanites is pinched in these ball float 4 both sides because of hands, flow through by soft flow dropper display 3.
Allow medicinal liquid P flow through two (high-order ditherings---comparatively trouble) of the method for hard flow dropper display 3:
Arms up (arriving the height of infusion bottle 1 basically) and keep flat hard flow dropper display 3 to allow the people, shakes this flow dropper display 3 slightly up and down back and forth, can allow medicinal liquid P flow through from the slit, side of this ball float 4.
Claims (2)
1. medical infusion dropper device with check function structurally comprises:
Be arranged on the infusion needle (6) of tube for transfusion (2) bottom, be arranged on the tube for transfusion (2) flow dropper display (3) and with this placed in-line flow regulator of flow dropper display (3) (5),
It is characterized in that:
In the middle of above-mentioned flow dropper display (3), also be provided with its diameter less than this flow dropper display (3) internal diameter and greater than the ball float (4) in transfusion aperture, this flow dropper display (3) bottom.
