Abstract
The invention discloses a use method for a medical infusion device capable of improving absolutely safe safety level. Based on the structure in the prior art, the device is characterized in that: a floating ball (4) of which the diameter is less than the inner diameter of a flow dropper display (3) and is greater than the infusion aperture on the lower part of the flow dropper display (3) is also arranged in flow dropper display (3) component; the overall process of the use method of the device is similar to that of the prior art; in order to finally float the floating ball (4) on liquid level of liquid medicine (P) in the vertical flow dropper display (3), the unique difference in the use of the device is that: the floating ball (4) which is positioned in the flow dropper display (3) is held by a hand through a soft flow dropper display (3), so that the liquid medicine (P) flows by a section part of a bulging space which is formed by deformation on the two sides; or, the hand is lifted and flatly placed on a hard flow dropper display (3), and the hard flow dropper display (3) is shaken left and right, and up and down, so that the liquid medicine (P) flows by a lateral gap 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 and the method for using thereof 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 through penetrating blood vessel syringe needle and along tube for transfusion reflux (tracing back) to human body external a segment distance or height ...
Summary of the invention
The present invention's purpose: be exactly through addressing the above problem a kind of improvement that proposes prior art.---make infusion techn further improved.
Key of the present invention is: in the medicinal liquid when to patient infusion was about to use up, the ball float in the infusion set can fall automatically carried out the continuation transfusion of blocking-up to patient.
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 get 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: in the process of patient being used medical apparatus and instruments, improved the medical safety grade of guaranteeing " perfectly safe " character and created condition.
Description of drawings
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
In order to realize the foregoing invention purpose, intend the technology below adopting:
The present invention structurally comprises: the infusion needle 6 that is arranged on tube for transfusion 2 bottoms; Be arranged on that the flow dropper display 3 on the tube for transfusion 2---it is produced and can adopt the soft transparent material; For example: " plastics "; Perhaps; Can adopt hard transparent material; For example: " glass "---and with flow dropper display 3 placed in-line flow regulators 5 (belonging to prior art), it is characterized in that: in the middle of above-mentioned flow dropper display 3, also be provided with its diameter less than these flow dropper display 3 internal diameters and greater than the ball float 4 in transfusion aperture, this flow dropper display 3 bottoms, it can adopt light plastic or other light materials on the liquid level that can swim in medicinal liquid P to process.
Method for using 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 following:
Let medicinal liquid P flow through one of method of soft flow dropper display 3 (flatten deformation method---more convenient):
Let staff pinch the ball float 4 that wherein is arranged in flow dropper display 3, can let 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 through soft flow dropper display 3.
Let 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 let the people, shakes this flow dropper display 3 slightly up and down back and forth, can let medicinal liquid P from the slit, side of this ball float 4, flow through.
---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 let ball float 4 from the top hole of flow dropper display 3, fill in 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.
