Description

Automatic alarming transfusion support

This utility model belongs to introduces the intravital technical field of medical instruments of people, particularly venous transfusion utensil with medium.

Before this utility model, the venous transfusion device of existing polytype and function, as YBDS-11 micro computer infusion pump, SE-1 transfusion controller etc. can be realized controlling automatically transfusion speed and report to the police automatically.In addition, CN86204200 automatic closing and alarm infusion set and transfusion magnetic controlled choked flow electronic alarm etc. can be realized the automatic warning of infusing and close.In hospital clinical practice, patient's number of infusing constantly increases, and medical personnel's labor intensity also constantly increases, no accompany personnel or when infusing night especially like this.Therefore, need the renewal product of a kind of simple, practical, safe, cheap automatic warning drip stand especially as existing drip stand.CN86204200 automatic closing and alarm infusion set is the principle design that equates with spring tension according to load on spring weight, it is simple in structure, but at present domestic each hospital uses the infusion bottle specification many, vial, plastic bottle are arranged, reach bottle falling etc., therefore this device versatility is poor, is subjected to certain limitation on the scope of application.The magnetic controlled choked flow electronic alarm of infusing in addition is in the Mo Feishi pipe, gravitation with magnetic float valve in managing, the process that controlling liquid is following realizes warning automatically, and this device is sensitive reliable, but uses this device will be equipped with special-purpose Mo Feishi pipe and increase transfusion device disinfectant workload, in addition, its transfusion surplus is minimum, does not meet the requirement of nursing staff to the transfusion surplus, and makes troubles to changing the continuous transfusion of bottle, therefore, practicality is relatively poor.For overcoming defective and the deficiency in the prior art, and designed a kind of new automatic warning drip stand.

The purpose of this utility model is a kind of infusion set that can report to the police automatically, close automatically of design, this device is applicable to various infusion bottles (as vial and plastic bottle), the transfusion surplus is about 30 milliliters, when transfusion is about to finish, automatically send alarm signal, remind medical personnel in time to handle, and can close automatically, avoid because the malpractice that the tube for transfusion air inlet is caused.This device is safe, reliable, simple, practical, and cost is low, alleviates medical personnel's labor intensity greatly.

Main points of the present utility model are: this drip stand includes the column on a Height Adjustable band chassis, a signal generator that is fixed on column cross bar one side, an electric appliance control box that is fixed on column cross bar opposite side, one is installed in the vertical electromagnetic valve of column, an electronic buzzer that is placed in the electric appliance control box, and end of bringing the air tube head into is connected to the polyethylene catheter on the electromagnetic valve.Utilize the light refraction principle, when liquid level drops to certain position in the infusion bottle, signal generator just sends signal, it is the photoelectric sensing signal, through comparing amplifying circuit, directly control electronic buzzer and report to the police, also directly control electromagnetism simultaneously and close action, close the infusion bottle intake channel, reach the effect of reporting to the police and closing.This principle of device is simple, and is simple in structure, is quick on the draw, safe and reliable.

Below in conjunction with drawings and Examples this utility model is described in further detail.

Fig. 1 is the drip stand structural representation of reporting to the police automatically.

Fig. 2 is this device automatic control circuit schematic diagram.

Automatically the warning drip stand includes a Height Adjustable column that has the chassis ［ 1 ］, a signal generation apparatus ［ 2 ］ that is fixed on column cross bar one side.Signal generation apparatus includes a fixed light source ［ 7 ］, can select 6.3V, 0.15A spot light lamp bulb for use.An emission unthreaded hole road ［ 8 ］, diameter is 5 millimeters.One receives unthreaded hole road ［ 9 ］, and straight line is 8 millimeters.The silicon photoelectric cell slice of a receiving optical signals ［ 10 ］, specification are 5 * 10 silicon cells.For preventing the interference of veiling glare in the ward, a cone ［ 11 ］ between emission duct and the reception unthreaded hole road of being fixed on that wraps in infusion bottle outside is arranged, select the opaque plastics material for use.In addition, a position adjustable board ［ 12 ］ of regulating the infusion bottle position is arranged, its important function just is to control the angle of light refraction and the surplus of regulating liquid.

The principle of its photoelectric sensing is: utilize the body of infusion bottle and the character shape of the tapering transition between the bottleneck, when light when the bottle of liquid is arranged, light reflects, light is departed from receive the unthreaded hole road, signal on the silicon cell a little less than, this moment, control circuit was in the normal infusion state, in the time of near the liquid in the bottle drops to light path gradually, the light refraction angle diminishes gradually, the optical signal that receives the unthreaded hole road strengthens the process comparison amplifier gradually and compares with the signal that presets, and provides corresponding alarm signal and drives relay with the air inlet closed electromagnetic valve.

Each element of the automatic control circuit of this device is placed in the electric appliance control box ［ 3 ］ that is fixed on column cross bar opposite side.Electronic buzzer ［ 4 ］ is selected FMO-27 type electronic buzzer for use, automatically send alarm sound, remind medical personnel in time to handle, one is installed in the polyethylene catheter ［ 6 ］ that a end that the vertical electromagnetic valve of column ［ 5 ］ and one has the air inlet syringe needle is connected on the electromagnetic valve and realizes closing automatically, when signal generator sends alarm signal, by relay control closed electromagnetic valve, cut off the air inlet gas circuit in the infusion bottle like this, transfusion slows down gradually, at last to stopping, preventing that bubble from entering in the transfusion catheter and the accident that causes.The DF-2-2 type electromagnetic valve that electromagnetic valve selects for use stainless steel material to make, power supply 220V, air pressure 0.8kgt/cm ²

This drip stand is simple in structure and adopt circuit common to realize automatic control, is quick on the draw, and is safe and reliable, is convenient to medical personnel's operation.Applicable to glass infusion bottle and plastic infusion bottle, the medicinal liquid surplus is about 30 milliliters, is convenient to change bottle transfusion continuously, through the hospital clinical probationary certificate, uses this drip stand patient to have a sense of security, and has alleviated medical personnel's labor intensity simultaneously greatly.This drip stand cost is low, easy to utilize.
