Abstract
The utility model provides a medical magnetic control transfusion alarm with automatic cut-off. The embodiment comprises a dropper (1), a liquid inlet (8) and a liquid outlet (6), wherein a column-shaped floater (2), the specific gravity of which is smaller than that of a transfusion medium, is arranged in the dropper (1); the bottom of the floater is provided with a permanent magnet (3) and a cushion (4); the liquid outlet is arranged just below the dropper (1); the outer bottom of the dropper (1) is provided with an armature (5); the outer side of the bottom of the dropper is provided with a magneto sensor (7) which is used as a trigger switch for an alarm system, and the magneto sensor (7) can be connected with various acoustooptic circuits. The alarm can automatically close a transfusion device to stop transfusion and to trigger the alarm system when the transfusion medium is about to be transfused up; the alarm can also connected to a calling system in a sickroom to realize united monitoring, which reduces nursing intensity.
Description
Affiliated technical field
This utility model relates to a kind of fluid level control device of medical infusion.
Background technology
At present, existing technology by a float valve realizes mainly that to the control of damming of medical infusion a proportion promptly is set less than infusion medium proportion in dropper, diameter is less than the float of dropper diameter greater than the liquid outlet diameter; When infusion medium used up, the liquid level in the dropper descended, and float with the liquid outlet sealing, is realized damming along with decline naturally.But this fluid level control device has only utilized the gravity of a float to the sealing of transfusion, and the pressure of its sealing is limited, therefore can not effectively realize damming.Can not avoid the backflow phenomenon of blood fully.Existing technology can not realize by a device the automatic-diversion closure and the warning of transfusion simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, provides a kind of automatic-diversion closure more effective, and the medical magnetic control transfusion automatic-diversion closure alarm device of can realize simultaneously infusing automatic-diversion closure and warning.
Technical solution of the present utility model is the magnetic characteristic that has utilized permanent magnet, a proportion is set less than infusion medium proportion in the dropper tube chamber of prior art; Diameter is connected with the gum elastic packing of suitable permanent magnet of a diameter and float and float bottom less than the column type float of dropper internal diameter greater than liquid outlet below float, three's glue is one.Liquid outlet is located under the packing, and establishes an armature under outside dropper.Further solution of the present utility model is to be provided with magneto sensor on the position of dropper near bottom outside, as the trigger switch of alarm or calling system.When transfusion liquid level higher, float buoyancy is the float come-up during greater than gravity and magnetic pull, becomes suspended state, the dropper conducting; Permanent magnet is away from magneto sensor, and magneto sensor is not under the action of a magnetic field of permanent magnet, and magnetron is opened a way.When infusion medium was intact soon, liquid level descended, and when float buoyancy during less than gravity and magnetic pull, float descends rapidly, and under the captivation extruding of permanent magnet and armature and the airtight liquid outlet that tightly coincide of dropper bottom, dropper stops to infuse.Magneto sensor is sensed under the action of a magnetic field of permanent magnet simultaneously, and the magnetron short circuit triggers and reports to the police or calling system.
The beneficial effects of the utility model are, can work under the situation that does not have nursing, reduce nursing staff's working strength, and it can automatically close tube for transfusion when infusion medium is intact soon; Trigger alarm or calling system simultaneously, notify the nursing staff in time to stop or change transfusion.Under the situation that the nursing staff can not in time arrive and handle, avoid bubble to enter the danger of human body and the backflow of body inner blood, patient is infused under the situation of safety, reduced intensity and the patient and the psychological pressure of nursing staff of transfusion nursing work.And the calling system that can be docked with in the ward just can be realized unified monitoring.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing is the vertical section structural map of this utility model and embodiment.
Among the figure 1, dropper, 2, float, 3, permanent magnet, 4, packing, 5, armature, 6, liquid outlet, 7, magneto sensor, 8, inlet.
The specific embodiment
In the accompanying drawings, dropper (1) is a garden column type hard tube; Dropper (1) outer bottom is connected with a u type armature (5) and can does and horizontally rotate, and system resets when changing liquid.A proportion is set less than infusion medium proportion in dropper (1) tube chamber; Diameter is connected with diameter permanent magnet (3) suitable with float (2) and the gum elastic packing (4) bottom float (2) less than the garden column type float (2) of dropper (1) internal diameter greater than liquid outlet (6) in the below of float (2); Float (2), permanent magnet (3) and packing (4) three's glue are one; Liquid outlet (6) is under packing (4); Magneto sensor (7) is located at dropper (1) outside near lower portion; Inlet (8) is on dropper (1) top.
Claims (2)
1, a kind of medical magnetic control transfusion automatic-diversion closure alarm device, comprise dropper, inlet and liquid outlet, it is characterized in that: dropper is the column type hard tube, in burette chamber, be provided with one than weighing less than infusion medium, diameter is less than the dropper internal diameter, greater than the column type float of liquid outlet, below float, be connected with suitable permanent magnet of a diameter and float and the gum elastic packing bottom float; Float, permanent magnet and packing three glue are one; The dropper outer bottom is connected with a u type armature; Liquid outlet is located at center under the dropper.
2, medical magnetic control transfusion automatic-diversion closure alarm device according to claim 1 is characterized in that: below the column type float permanent magnet is housed, is provided with magneto sensor in the dropper outside near lower portion.
