Description

A kind of little negative pressure triggers alarming device
Technical field
This utility model relates to a kind of little negative pressure and triggers alarming device, particularly relates to a kind of alarming device of realizing alarm according to transfusion device pressure minor variations.
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, not having gives the alarm 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 purpose of this utility model is to provide a kind of deficiency that prior art exists that overcomes, and can realize the alarming device that transfusion finishes and reports to the police automatically according to transfusion device pressure minor variations.In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of little negative pressure triggers alarming device, particularly a kind of alarming device of realizing alarm according to transfusion device pressure minor variations, comprise set of cells 7, alarm indicator 5, it is characterized in that it also includes seal nipple 1, capillary airway 3, little negative pressure trigger 4, alarm device 6, its structure is: seal nipple 1 connects capillary airway 3, and capillary airway 3 other ends join by sealing cap 2 and little negative pressure trigger 4; Little negative pressure trigger 4 one ends are connected with set of cells 7, and 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 alarming device according to transfusion device pressure minor variations realization alarm, its little negative pressure trigger 4 is made up of pressure detecting chamber 4-1, air pressure sensing chip 4-2, fixed electrode 4-3, oscillating electrode 4-4 and pressure detecting chamber capping 4-5.
Described alarming device according to transfusion device pressure minor variations realization alarm, its fixed electrode 4-3 is arranged on the side of pressure detecting chamber 4-1, and oscillating electrode 4-4 is corresponding every sky with fixed electrode 4-3, forms the open type trigger.
The described alarming device of realizing alarm according to transfusion device pressure minor variations, its air pressure sensing chip 4-2 is arranged on the outside of oscillating electrode 4-4,4-4 contacts with oscillating electrode, and the small depression action of air pressure sensing chip 4-2 can promote oscillating electrode 4-4 and move and connect with fixed electrode 4-3 to fixed electrode 4-3.
Described alarming device according to transfusion device pressure minor variations realization alarm adopts capillary airway 3 to connect between its little negative pressure trigger 4 and the transfusion device, capillary airway 3 adopts seal nipple 1 to be connected with tube for transfusion.
The applicant's accomplice application also have a kind of novel intravenous transfusion device, they can be used in combination.The beneficial effects of the utility model are: the monitoring infusion device can the complete monitoring infusion process, and finishing in transfusion produces alarm signal at once, notifies medical personnel in time to handle, and reduces medical personnel's fruitless labour, harmonious doctor-patient relationship.This utility model 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.
