Abstract
The invention discloses a safe and reliable device for automatically detecting ending of transfusion and relates to the technical field of medical auxiliary equipment. A shading shell is internally provided with a liquid tube groove, a transfusion tube is fixed into the liquid tube groove, a light-emitting unit and a light detection unit is arranged on the two sides of the transfusion tube, the light-emitting unit emits incident rays of a certain angle, the light detection unit detects reflection rays of a certain angle, and a specific geometric included angle is formed by the direction of the incident rays and the direction of the reflection rays and the liquid tube groove according to the optical principle of total reflection. Through an optical total reflection effect of a gas-liquid interface, whether the gas-liquid interface passes through a preset detection point or not is detected, and thus whether transfusion is ended or not is judged; the device can automatically judge whether transfusion is ended or not and give out an audible and visual alarm to remind medical staff, can be widely applied to the medical field, avoids occurrence of transfusion accidents and relieves the care burden of patients, families and medical workers, materials used for the device is simple and convenient and easy to obtain, and the device is convenient to implement and low in cost.
Description
Technical field
The present invention relates to the device that a kind of safe and reliable automatic detection transfusion terminates, belong to technical field of medical auxiliary equipment.
Background technology
During current medical infusion instils, the monitoring terminated for infusing is main wastes time and energy still based on manual observation, there is no reliable and effective especially method to the automatic detection that transfusion instillation terminates.
Summary of the invention
For the problems referred to above, the technical problem to be solved in the present invention is to provide the device that a kind of safe and reliable automatic detection transfusion terminates.
The device that the automatic detection transfusion that the present invention is safe and reliable terminates, it comprises luminescence unit, inspection light unit, liquid tube seat, incident ray, reflection ray, tube for transfusion, emergent ray, liquid-gas interface and shading shell, liquid tube seat is provided with in shading shell, tube for transfusion is fixed in liquid tube seat, luminescence unit and inspection light unit are arranged on the both sides of tube for transfusion, luminescence unit sends the incident ray of special angle, the reflection ray of inspection light unit inspection special angle, the direction of incident ray and reflection ray forms specific geometric angle according to optical total-reflection principle and liquid tube seat.
Beneficial effect of the present invention: it can overcome the drawback of prior art, structural design is unique novel, by the optical total-reflection effect of liquid-gas interface, whether detect liquid-gas interface through default test point, and then judge whether transfusion terminates, this device can differentiate that whether transfusion terminates automatically, and send acousto-optic warning prompting medical personnel, can apply widely and medical field, avoid the generation of transfusion accident, alleviate patient, the nurse burden of family members and health care workers, and the equipment that this device uses is easy, be easy to obtain, device is convenient to realize, cost is comparatively cheap.
accompanying drawing illustrates:
For ease of illustrating, the present invention is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is that the present invention is at the ongoing status architecture schematic diagram of transfusion;
Fig. 2 is that the present invention infuses the status architecture schematic diagram after terminating.
detailed description of the invention:
As shown in Figure 1-2, this detailed description of the invention is by the following technical solutions: it comprises luminescence unit 1, inspection light unit 2, liquid tube seat 3, incident ray 4, reflection ray 5, tube for transfusion 6, emergent ray 7, liquid-gas interface 8 and shading shell 9, liquid tube seat 3 is provided with in shading shell 9, tube for transfusion 6 is fixed in liquid tube seat 3, luminescence unit 1 and inspection light unit 2 are arranged on the both sides of tube for transfusion 6, luminescence unit 1 sends the incident ray 4 of special angle, inspection light unit 2 detects the reflection ray 5 of special angle, the direction of incident ray 4 and reflection ray 5 forms specific geometric angle according to optical total-reflection principle and liquid tube seat 3.
Operation principle of the present invention is: when transfusion is carried out, liquid is full of in tube for transfusion 6, the direction that now incident ray 4 can keep original forms emergent ray 7 through tube for transfusion 6, emergent ray 7 is consistent with the direction of incident ray 4, can not sense by tested smooth unit 2, with this, system judges that liquid-gas interface 8 does not arrive test point, and then judge that medicinal liquid is not totally lost, can not alert trigger;
At the end of transfusion, liquid-gas interface 8 in tube for transfusion 6 declines gradually, when liquid-gas interface 8 is through the default test point of this device, incident ray 4 is mapped on liquid-gas interface 8, because liquid is optically denser medium, gas is optically thinner medium, incident ray 4 can be totally reflected on liquid-gas interface 8, form reflection ray 5, reflection ray 5 can arrive inspection light unit 2 according to total reflection principle along the reflection path preset, inspection light unit 2 senses reflection ray 5, judges that liquid-gas interface 8 arrives test point, sends the alarm sounds that medicinal liquid has been totally lost.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
