Abstract
The utility model relates to a signal switch for a transfusion bottle lack of medicine. The utility model mainly solves the technical problems that the liquid level of a transfusion bottle of a transfusion device of the existing hospital bed needs to be monitored by people, a tail end switch of an alarm sick bed is controlled manually, etc. The utility model has the technical scheme that a bottle opening of a medicine bottle is sheathed with a rubber bottle cover in a matching mode; a tail end switch of an alarm sick bed is arranged on a sick bed or near the sick bed; the end of a needle tip of a liquid level needle penetrates through the rubber bottle cover of the medicine bottle to enter the medicine bottle; the end of the needle tip of the liquid level needle is provided with liquid level detecting poles and liquid lower poles with different heights; the liquid level detecting poles of the liquid level needle are higher than the liquid lower poles and are respectively connected with the input end of an amplifying circuit; the output end of the amplifying circuit is connected with a coil of a miniature relay; a normal opened contact switch of the miniature relay is connected with the tail end switch of the alarm sick bed. Through the electrical conductivity of physic liquor in the transfusion bottle, the utility model uses the liquid level needle to detect the liquid level in the bottle and generate electric potential, the utility model controls the tail end switch of the alarm sick bed to be turned off or be automatically turned on through the amplifying circuit and the miniature relay, and the automatic alarm function is realized.
Description
Technical field
This utility model relates to a kind of signaling switch, and particularly a kind of medical infusion bottle lacks the Signal-controlled switch that medicine is reminded.
Background technology
At present, the infusion bottle of hospital bed infusion set lacks medicine, generally is after observing discovery by the entourage, more manually by or pull alarm sick bed limit switch, send the signal prompt medical personnel.This by the artificial device that monitors the infusion bottle liquid level and manually send signal, when entourage's carelessness or when dozing off, infusion bottle be in case scarce medicine then can't allow medical personnel know, so that into phenomenon such as air, blood back appears in tube for transfusion, influences patient treatment.Therefore, it requires the entourage must concentrate one's energy to observe, and more can not sleep.
Summary of the invention
The purpose of this utility model provides a kind of energy and adapts to the signaling switch medical alarm device of various differences, can trigger alarm sick bed termination automatically when infusion bottle lacks medicine.
The technical scheme that its technical problem that solves this utility model adopts is: it cooperates suit rubber bottle cap 5 on the bottleneck of the medicine bottle 1 that medicinal liquid 4 is housed, and on one's sick bed or alarm sick bed limit switch 10 is installed near it, the rubber bottle cap 5 that the needle tip of liquid level pin 6 passes medicine bottle 1 is gone forward side by side in the medicine bottle 1, the needle tip of liquid level pin 6 is established the utmost point 3 under the highly different Level Detection utmost points 2 and the liquid, the Level Detection utmost point 2 of liquid level pin 6 is higher than the utmost point 3 under the liquid and joins with the input of amplifying circuit 7 respectively, the coil of the outfan of amplifying circuit 7 and miniature relay 8 joins, and the normally opened contact switch of miniature relay 8 and alarm sick bed limit switch 10 join.Described liquid level pin 6 is a bipolar pin or is formed in parallel by two one pole pins.Described amplifying circuit 7 is coupled to each other the signal amplification circuit that constitutes for integrated circuit or modular circuit or by discrete original paper.It is power autonomous that amplifying circuit 7 and miniature relay 8 connect this device, or the power supply of device sick bed limit switch 10 taking alarm.
The beneficial effects of the utility model are, the electric conductivity that it has utilized the infusion bottle inner liquid medicine to have usually, break-make by the utmost point under the Level Detection utmost point and the liquid on the liquid level control liquid level pin in the bottle, allow the potential balance of input amplifier be zero or unbalance generation current potential, make the outfan control miniature relay coil losing electricity or the energising of amplifying circuit, allow the miniature relay normally opened contact keep open circuit or adhesive conducting, control that medical alarm sick bed limit switch cuts out or open automatically.It must the entourage level condition of the medicine bottle of look-out transfusion constantly, when the infusion bottle inner liquid medicine when dripping off, will connect medical alarm sick bed limit switch automatically, make alarm send signal, the prompting medical personnel in time handle.
Description of drawings
Fig. 1 is a structural principle sketch map of the present utility model.
Among the figure: 1. medicine bottle, 2. the Level Detection utmost point, the 3. utmost point under the liquid, 4. medicinal liquid, 5. rubber bottle cap, 6. liquid level pin, 7. amplifying circuit, 8. miniature relay, 9. hand switch, 10. alarm sick bed limit switch.
The specific embodiment
Embodiment 1, this utility model is by intert liquid level pin 6 in rubber bottle cap 5, liquid level pin 6 enters in the medicine bottle 1, the utmost point 3 often is immersed in the medicinal liquid 4 in the medicine bottle 1 under the liquid of liquid level pin 6, the Level Detection utmost point 2 of liquid level pin 6 is higher than the utmost point 3 under the liquid, the utmost point 3 all joins with the input of amplifying circuit 7 under the Level Detection utmost point 2 of liquid level pin 6 and the liquid, the coil of the outfan of amplifying circuit 7 and miniature relay 8 joins, the scarce medicine signaling switch of infusion bottle that the normally opened contact of miniature relay 8 and alarm sick bed limit switch 10 join and constitute, when the medicinal liquid position in the infusion bottle is higher than the Level Detection utmost point 2 of liquid level pin 6, the utmost point 3 is that the medium conduction forms the loop by medicinal liquid 4 under the Level Detection utmost point 2 and the liquid, after manually switch 9 conductings provide power supply, allow amplifying circuit 7 the input conducting and obtain a current potential opposite with operating potential, the potential balance that causes amplifying circuit 7 inputs is zero, outfan does not have voltage, miniature relay 8 is not worked, the 10 not conductings of medical alarm sick bed limit switch, the infusion set operate as normal.When the medicinal liquid position in the infusion bottle is lower than the Level Detection utmost point 2 of liquid level pin 6, even hand switch 9 conductings provide power supply, there is not medicinal liquid 4 to open circuit under the Level Detection utmost point 2 of liquid level pin 6 and the liquid between the utmost point 3 for the medium conduction becomes, cause current potential opposite on amplifying circuit 7 inputs to disappear with operating potential, amplifying circuit 7 is provided the signal amplification back of operating potential to the coil of miniature relay 8, drive miniature relay 8, allow the normally opened contact adhesive of miniature relay 8, make medical alarm sick bed limit switch 10 automatic conductings, make alarm send signal, the prompting medical personnel in time handle.It is mainly by utilizing the electric conductivity of infusion bottle inner liquid medicine, producing current potential by liquid level in the liquid level pin induction bottle closes or opens automatically through amplifying circuit and miniature relay control alarm sick bed limit switch, thereby realize automatic warning function, it can adapt to various medical alarm device.Consult Fig. 1.
Obviously, described liquid level pin 6 both can adopt a bipolar pin, also can adopt by two one pole pins to be formed in parallel.Described amplifying circuit 7 both can adopt common integrated amplifier, also can adopt the modular circuit amplifying circuit, can also be to be coupled to each other the common amplifying circuit that constitutes by discrete original paper.The power supply of amplifying circuit 7 and miniature relay 8 both can install power autonomous power supply by this, also can be by the power supply power supply of alarm sick bed limit switch 10.
