Background technology
In the venous transfusion process, when the medicinal liquid in the transfusion device during, if untimelyly stop transfusion or change infusion bottle near emptying, can cause blood back blood coagulation phenomenon, give and continue transfusion formation obstacle, increase extra misery to the patient, also form thrombosis easily, bring potential hazard to patient.Existing transfusion device comprises bottle plug puncture unit, air filter, flow observation bucket, tube for transfusion, flow regulator, liquid medicine filter, venoclysis needle, tool does not give the alarm and reminds medical personnel's function, all the time need people's nurse in the use, nursing work load is made mistakes greatly and easily, and conflict between doctors and patients takes place frequently.
Summary of the invention
The object of the present invention is to provide a kind of deficiency that prior art exists that overcomes, can change the monitor of realizing that transfusion finishes and reports to the police automatically according to tube for transfusion pressure.In order to achieve the above object, technical scheme of the present invention is achieved in that a kind of transfusion alarm monitor, particularly change the monitor of realizing alarm according to tube for transfusion pressure, comprise set of cells 7, alarm indicator 5, it is characterized in that it also includes needle-like joint 1, airway 3, air pressure microswitch 4, alarm device 6, its binding connects airway 3 for needle-like joint 1, airway 3 other ends and air pressure microswitch 4 are joined, air pressure microswitch 4 one ends are connected with set of cells 7 simultaneously, the other end is connected with an end of alarm indicator 5 and alarm device 6, and set of cells 7 other ends are connected with the other end of alarm indicator 5 with alarm device 6.
Described a kind of monitor according to tube for transfusion pressure variation realization alarm, its air pressure microswitch 4 is made up of pressure chamber 4-1, pressure-sensitive sheet 4-2, electrode 4-3, electrode contacts 4-4.
Described a kind of monitor of realizing alarm that changes according to tube for transfusion pressure, its pressure-sensitive sheet 4-2 can be arranged on the upside of pressure chamber 4-1, also can be arranged on the downside of pressure chamber 4-1, electrode 4-4 can be in the outside of pressure chamber 4-1, also can be in the inside of pressure chamber 4-1.
Described alarm monitor for transfusion adopts airway 3 to connect between its air pressure microswitch 4 and the tube for transfusion, airway 3 adopts the needle-like joint 1 that has protective cap 2 to be connected with tube for transfusion.
Described alarm monitor for transfusion, in order to reach hygienic requirements, airway 3, needle-like joint 1 can adopt disposable products.In addition, by design to barochamber 4-1 and airway 3 calibers, can be when tube for transfusion pressure change, control medicinal liquid liquid level rises in small scope, does not touch the needle-like joint, can not bring the liquid medicine contamination problem.
Beneficial effect
The intravenous transfusion device in addition of the applicant's accomplice application, they can be used in combination.The invention has the beneficial effects as follows: the monitoring infusion device can the complete monitoring infusion process, and finishing in transfusion produces warning signal at once, notifies medical personnel in time to handle, and reduces medical personnel's fruitless labour, harmonious doctor-patient relationship.The present invention adopts the air pressure principle to monitor, and does not consume any electric weight in the omnidistance work of infusion monitoring, only expends small amount of electrical energy when transfusion finishes alarm, meets the situation requirement of conservation-minded society's construction, is a kind of practical technique of low-cost high energy efficiency.
