Abstract

The invention relates to a medical intravenous injection system with real-time monitoring and timing control functions. The medical intravenous injection system comprises an infusion bottle, an infusion tube, a drip tube and a stopping and clamping wheel, wherein an infrared sensor is arranged on one side of the drip tube, the stopping and clamping wheel is of an eccentric wheel structure and is driven by a stopping and clamping motor, and the infrared sensor controls the stopping and clamping motor to turn on or turn off the stopping and clamping wheel by sensing the drip signals in the drip tube. The medical intravenous injection system further comprises a pressure sensor arranged at the injection end at the lower end of the infusion tube and a timing controller for controlling the stopping and clamping motor, and the pressure sensor detects the liquid pressure at the injection end to control the stopping and clamping motor. The medical intravenous injection system has the characteristics that the infrared sensor is used to detect the state signals of injection drips at the drip tube and the pressure sensor is used to detect the pressure signals at the injection end, the turning-on or turning-off of the stopping and clamping motor is controlled according to the signals respectively, and the clamping and loosening of the stopping and clamping wheel are controlled; safety injection operation is further guaranteed by the timing controller; the medical intravenous injection system does not need manual monitoring and is simple to operate, reliable in control and safe to use.

Description

Real-time monitoring and time-controlled medical intravenous system

Technical field

The present invention relates to field of medical technology, the watch-dog of especially intravenous drip.

Background technology

At present, use in hospital and during fluid infusion, drip bag or drop bottle height are hung on shelf, the weight power of injection is relied on to inject patient, easily cause due to blood backflow phenomenon under healthcare givers or the careless situation of patient during high hanging injection, therefore healthcare givers is needed constantly to monitor, and be easy to tired during manual monitoring, and high hanging injection uses inconvenience.

Summary of the invention

The applicant, for the above-mentioned shortcoming of existing transfusion injection device, provides one to monitor conveniently, manipulates simply real-time monitoring and time-controlled medical intravenous system.

The technical solution adopted in the present invention is as follows:

A kind of monitoring in real time and time-controlled medical intravenous system, comprise dropping bottle, tube for transfusion, dropper and stop clip wheel, the side device of described dropper has infrared sensor, described only clip wheel is eccentric wheel structure, it is by only folder motor driving, and the described infrared sensor drop signal passed through in induction dropper controls described stopping and presss from both sides electric motor starting or close described only clip wheel;

Also comprising the pressure transducer that is installed on dispensing end place, tube for transfusion lower end and the timing controller for controlling described only folder motor, described in the fluid pressure that described pressure transducer detects dispensing end place controls, only pressing from both sides motor.

Beneficial effect of the present invention is as follows:

The present invention adopts the status signal of the injection drop at infrared sensor detection dropper place, the pressure signal of pressure transducer detection dispensing end, only press from both sides startup or the closedown of motor respectively, thus control stops the clamping of clip wheel and relaxes according to signal control; Timing controller is adopted to ensure safe injection operation further.The present invention without the need to manual monitoring, have simple to operate, control feature that is reliable, use safety.

Accompanying drawing explanation

Fig. 1 is operation principle block diagram of the present invention.

In figure: 1, dropping bottle; 2, dropper; 3, clip wheel is stopped; 4, infrared sensor; 5, only motor is pressed from both sides; 6, tube for transfusion; 61, dispensing end; 7, pressure transducer; 8, timing controller.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As shown in Figure 1, the dropping point injection supervising device of the present embodiment, comprise dropping bottle 1, tube for transfusion 6, dropper 2 and stop clip wheel 3, the side device of dropper 2 has infrared sensor 4, only clip wheel 3 is eccentric wheel structure, it drives by only pressing from both sides motor 5, and infrared sensor 4 controls only to press from both sides motor 5 by the drop signal in induction dropper 2 and starts or close apolipsis clip wheel 3.Wherein, only the motor shaft of folder motor 5 is with only clip wheel 3 eccentric shaft to being connected, and only folder motor 5 drives only clip wheel 3 to rotate to realize to the clamping of tube for transfusion 6 or relaxes.

In order to improve the safety of transfusion further, only folder motor 5 is also electrically connected with timing controller 8, and timing controller 8 starts only folder motor 5 by setting maximum injection time controling; In dispensing end 61 place, tube for transfusion 6 lower end, device has pressure transducer 7, and the fluid pressure that pressure transducer 7 detects dispensing end 61 place controls only folder motor 5.

The present invention adopts the pressure signal that infrared sensor 4 detects the status signal of the injection drop at dropper 2 place, pressure transducer 7 detects dispensing end 61, controls startup or the closedown of only folder motor 5 respectively according to signal, thus controls the clamping of only clip wheel 3 and lax; Timing controller 8 is adopted to ensure the injection operation of safety further.The present invention without the need to manual monitoring, have simple to operate, control feature that is reliable, use safety.

More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
