The utility model discloses an automatic alarm control device for Murphy tube transfusion. The automatic alarm control device comprises an infrared sensor, an electromagnetic valve switch, an alarm, a controller and a shell, wherein the infrared sensor comprises an infrared ray emitting end and an infrared ray receiving end; the infrared ray emitting end is used for emitting inclined infrared light to the inside of a Murphy tube; the infrared ray receiving end is used for receiving infrared light emitted by the infrared ray emitting end through the inner liquid surface of the Murphy tube; the electromagnetic switch is used for closing the transfusion tube; the alarm is used for transmitting an alarm signal; the controller is used for controlling the electromagnetic valve switch and the alarm; and the shell is fixed on the Murphy tube, and is used for fixing the infrared sensor, the electromagnetic valve switch, the alarm and the controller. Due to the adoption of the automatic alarm control device, a liquid can be stopped from flowing downwards automatically, a certain liquid surface is left in the Murphy tube, and medical personnel can replace bottles for performing continuous transfusion conveniently; and meanwhile, an alarm is made, so that the phenomenon of blood return caused by late stop is avoided, the transfusion safety feel of a patient is improved under the condition of freeness from accompanying personnel or night transfusion, and the working strength of the medical personnel can be lowered.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically relates to a kind of can automatically control, and the controller for transfusion device of alarm.
Technical background
Because existing transfusion device does not possess after the liquid of being totally lost and automatically stops, and reach the function of alarm, so in the process of transfusion, must someone see, supervising at any time transfusion and whether finishing, brought a lot of inconvenience for household and medical personnel.Owing to can not when being totally lost liquid, stop timely, may cause blood back, cause patient's fear.Simultaneously, also may be lower than Mo Feiguan by the liquid level in the tube for transfusion when medical personnel change infusion bottle, the air in the Mo Feiguan not inputted human body for making when infusing, cause thrombosis, this just brings the inconvenience of a lot of operations to medical personnel.
Patent Office of the People's Republic of China discloses a CN 2827400Y patent on October 18th, 2006, name is called automatic alarm transfusion device.This transfusion device is by switch, and infrared emitting end and infrared receiver end form.Float falls the luxuriant and rich with fragrance pipe of China ink lower end closed when transfusion finishes, medicinal liquid stops to flow, and infrared emitting end and receiving terminal are positioned at homonymy simultaneously, because float has dropped to the position of appointment, the signal that reflects through float that the infrared receiver end has received that transmitting terminal sends begins to report to the police this moment.The shortcoming of this transfusion device is, is switch because this transfusion device adopts, so when transfusion finished, float was with the channel enclosed between the tube for transfusion of the luxuriant and rich with fragrance Guan Yuqi of China ink lower end, causes in the Mo Feiguan airtightly, can not directly change infusion bottle and carry out continuous transfusion.Simultaneously, existing other infusion alarm, remaining liquid level in the luxuriant and rich with fragrance pipe of China ink after can not being controlled at freely transfusion and finishing, since clinically the doctor generally in Mo Feiguan the residue liquid level be not less than three/for the moment changing-over infusion bottle carries out continuous transfusion, and (being convenient to after the complete transfusion of the changing-over luxuriant and rich with fragrance pipe of extruded ink makes under the liquid Rapid Flow in the bottle, and be unlikely to the air extrusion in the Mo Feiguan is entered in the tube for transfusion of Mo Fei pipe lower end, cause thrombosis), carry out continuous transfusion so also be not easy to medical personnel's changing-over infusion bottle.
Summary of the invention
The problem that this utility model solves is, remaining medicinal liquid can stop to flow automatically in the tube for transfusion after transfusion is finished, and remaining liquid level can freely be controlled (be convenient to the changing-over infusion bottle and carry out continuous transfusion) in the Mo Feiguan, give the alarm simultaneously, remind medical personnel's changing-over infusion bottle to carry out continuous transfusion, or extract the syringe needle stopping infusion.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of automatic alarm control device for the luxuriant and rich with fragrance pipe transfusion of China ink is characterized in that, comprising:
One infrared sensor, comprise infrared emitting end and infrared receiver end, described infrared emitting end is used for the infrared light that emission one is tilted in the luxuriant and rich with fragrance pipe of described China ink, and described infrared receiver end is used for receiving from the infrared ray of the infrared emission end emission infrared light through the luxuriant and rich with fragrance intraluminal fluid surface launching of China ink;
One electromagnetic valve switch is arranged on the tube for transfusion of Mo Fei pipe lower end for closing tube for transfusion;
One alarm is used for sending alarm signal;
One controller is used for controlling described electromagnetic valve switch and alarm, and when described infrared receiver termination was received infrared light through the luxuriant and rich with fragrance intraluminal fluid surface launching of China ink, controller controlled described alarm equipment alarm and cuts out described electromagnetic valve switch;
One housing is fixed on the luxuriant and rich with fragrance pipe of described China ink, is used for fixing described infrared device sensor, electromagnetic valve switch, alarm and controller.
The upper end of described shell is provided with the upper fixedly clip that is connected with the Mo Feiguan upper end, and the lower end of shell is provided with the lower fixedly clip that is connected with the luxuriant and rich with fragrance pipe of China ink lower end.
Be provided with groove on the described electromagnetic valve switch, the luxuriant and rich with fragrance pipe of described China ink lower end tube for transfusion is arranged in the described groove.
Liquid level when transfusion finishes in the luxuriant and rich with fragrance pipe of China ink can constantly descend, when dropping to preset height, total reflection can occur on the surface of liquid level in the infrared ray that the infrared emitting end sends, infrared ray after total reflection is mapped to the infrared receiver end, and receiving terminal passes to the infrared induction circuit with the infrared signal that receives.The infrared induction circuit is connected, and signal amplification circuit and solenoid valve control circuit are also connected simultaneously.Because the connection of signal amplification circuit, alarm is started working.Simultaneously, because the connection of solenoid valve control circuit, the tube for transfusion that electromagnetic valve switch will be clipped in wherein flattens, and the liquid in the tube for transfusion stops to flow.
This utility model is behind infusion-completed, can automatically make liquid stop to give the alarm simultaneously to dirty, avoid the blood back phenomenon because in time not stopping to occur, increase the patient without accompany personnel the time or the security of transfusion when infusing night, can alleviate medical personnel's working strength.And remaining liquid level can be by regulating the angle of infrared emitting end in the Mo Feiguan, realize that free control (prevents after having changed infusion bottle, air in the Mo Feiguan enters in the tube for transfusion of Mo Fei pipe lower end, thrombosis occurs), be very easy to medical personnel and carry out the operation of continuous transfusion to patient's changing-over infusion bottle.Utilized simultaneously all reflective light principle, make the infrared ray of launching substantially the same with the ultrared intensity that receives, effectively be different from other light, the signal that the infrared receiver end identification of being more convenient for receives, the precision when greatly having improved controller work.
