Abstract
The utility model provides a self-close type transfusion device with an alarm interface, which is used in a medical system to realize the self-close when the transfusion finishes and the output of the automatic alarming signal. The lower part of the transfusion device is transformed into a cone-shaped funnel; a silica gel floating ball is added into an observing drum. The floating ball goes down to the cone-shaped funnel with the descending of a liquid surface when the transfusion of the liquid medicine finishes; so a liquid channel is sealed and the self-close of the liquid transfusion is realized and the blood returning problem is solved. A three-way tube is added at the lower part of the observing drum and an outlet is sealed by a silica gel cover. During the normal transfusion or when the liquid transfusion finishes, the air pressure direction in a branch tube changes; the changes of the pressure states can trigger an external alarming event and then a sound-light alarm and a remote alarm are produced.
Description
Affiliated technical field
This utility model relate to a kind of have alarm interface from the cut-off type transfusion device, can finish in the medical system transfusion back automatic cut-off that finishes, prevent that the blood back phenomenon from taking place, and can realize audible and visual alarm and remote alarm in conjunction with warner.
Background technology
At present, existing transfusion device device has a variety of, partly is made up of bottle plug puncture unit, air filter, observation drum (dropper and dropping funnel), pipeline, flow regulator, liquid medicine filter, venoclysis needle etc. basically.In the transfusion operation of reality, because transfusion device self can't carry out automatic cut-off after liquid is totally lost, therefore usually cause patient's blood back phenomenon easily, bring extra misery to patient, form obstacle for continuing transfusion.In addition,, need the staff wage adjustment whole though have flow regulator on the existing transfusion device, can automatic cut-off, if therefore transfusion finishes and finds untimelyly, still can cause blood back to take place.In addition, transfusion device is owing to be passive equipment, so self can't initiatively send warning signal, can't notify medical personnel in time to handle.
Summary of the invention
In order to solve this problem that present transfusion device exists, this utility model design improves existing transfusion device on structure.Not only realize the automatic cut-off that transfusion finishes, also reserved alarm interface, can produce triggering signal, send audible and visual alarm, notice families of patients or medical personnel in time handle.
The technical problem that solves
This utility model mainly solves two problems: solving 1, that existing transfusion device equipment transfusion finishes can not automatic cut-off, causes blood back, increases patient's misery, causing transfusion to interrupt, and by improving, can realize the transfusion automatic cut-off that finishes; 2, existing fluid delivery apparatus is infused to finish and can't be produced active alarm, the problem of notifying medical personnel or family members in time to handle.By increasing interface, realize the automatic triggering signal output that transfusion finishes.
The technical scheme that its technical problem that solves this utility model adopts is:
1, the observation drum bottom of transfusion device is improved, be transformed into funnel shape.Observing silica gel suspension ball of the inner increase of drum.The suspension ball adopts nontoxic insoluble silica gel goods, and density is less than general medicinal liquid density.When in observing drum medicinal liquid being arranged, ball float floats on the liquid level; After the bottle inner liquid medicine was totally lost, ball float can drop in the conical hopper of observing the drum bottom along with liquid level.Because the pliability of silica gel goods itself, slight deformation can take place in self, produces external pressure, and the complete closed fluid passage is realized by the transfusion effect, because external pressure and blood pressure balance can not cause blood back.
2, increase a three-way interface below observing drum, the 3rd arm direction is upwards 45 degree of horizontal plane, increases air filtration pieces in the arm, and the silica gel sheath shutoff is adopted in the exit.Because the action of gravity of air pressure and medicinal liquid self, when the normal infusion state, its pressure is greater than the medicinal liquid pressure in tee T external pressure and the threeway, therefore produce outside pressure, because air can't overflow in the silica gel shutoff, arm, medicinal liquid can not arrive the mouth of pipe.After medicinal liquid is totally lost, ball float shutoff liquid-transport pipe-line, therefore the transfusion device internal pressure can produce an inside pressure along tee T less than the medicinal liquid pressure in threeway external pressure and the threeway.Detect this pressure state and change, can trigger the external alarm incident, produce audible and visual alarm by external alarm equipment.When not connecing warner, the tee T interface maintains the original state and gets final product.In addition, this three-way interface also can be used for adding auxiliary medicinal liquid.
Beneficial effect
The beneficial effects of the utility model are, can realize the transfusion automatic cut-off of transfusion device in low cost, have reserved interface for outside audible and visual alarm simultaneously, can cooperate multiple mode to realize the transfusion notice that finishes.Little to former transfusion device structural modification, cost is low, realizes suitability for industrialized production easily, and does not change medical personnel's work habit, is easy to be extended and applied, and effectively improves nurse job efficient, reduces patient's misery.

The specific embodiment
In Fig. 1, the observation drum bottom of transfusion device is improved, be designed to funnel shape, conical hopper bottom and down pipe seamless combination.
In Fig. 1, observing drum indoor design suspension ball, suspension ball and conical hopper constitute globe valve.The suspension ball adopts nontoxic insoluble silica gel goods, and density is less than medicinal liquid density, the about 5mm of diameter.When in observing drum medicinal liquid being arranged, ball float floats on the liquid level.
In Fig. 2, after observation drum inner liquid medicine was totally lost, ball float can drop in the conical hopper of observing the drum bottom along with liquid level.Because the pliability of silica gel goods itself, self can produce slight deformation, produces external pressure, and the complete closed fluid passage is realized by the transfusion effect, because external pressure and blood pressure balance can not cause blood back.
In Fig. 1, the 3cm place increases a tee T interface below observing drum, and the 3rd arm direction is upwards 45 degree of horizontal plane, can increase air filtration pieces in case of necessity in arm, prevents outside unclean air admission.The soft silica gel sheath shutoff of insoluble in water is adopted in the arm exit.Silicone envelope requires material softness, and water insoluble and organic liquid can produce distortion under pressure, improves tightness.
