Abstract

The utility model relates to a transfusion autoalarm capable of calling nurse automatically after the transfusion, which uses the quality change of a transfusion bag to control the alarm. The transfusion autoalarm consists of an adjusting screw plate, a spring, a tension rod pothook, an upper junction, a lower junction, a battery unit, an alarm lamp and alarm sound. When the transfusion is in progress, the transfusion bag (or bottle) is hung on the tension rod pothook and the gravity of the transfusion bag makes the tension rod pothook compress the spring which contracts downwards and then the upper junction is separated from the lower junction. When the liquid medicine in the transfusion bag is used up, the tension rod pothook ascends under the elasticity action of the spring and the junctions are connected; the power supply current forms a path; the alarm lamp and the alarm sound are switched on; and the alarm is realized. The utility model has the advantages of simple structure, convenient use, safety and reliability, thus avoiding the blood backflow and other medical malpractices caused by not changing the transfusion bag (or bottle) and stoping the transfusion timely.

Description

Automatic alarm for infusion

Technical field

Automatic alarm for infusion relates to a kind of transfusion safety device, belongs to medical instruments field.

Technical background

Though hospital has developed calling device for patient infusion at present, still needs the personnel of cultivating and looking after to observe transfusion at any time, so that nurse call is not incured loss through delay in transfusion when being over.But often transfusion finishes and fails in time to be found, causes blood to reflux, even malpractice takes place.In order to prevent that accident from taking place, need a kind of autoalarm that can call out automatically of exploitation, when transfusion finishes, can at once the nurse please be removed transfusion.

Summary of the invention

This utility model is to utilize the quality of transfusion bag to realize reporting to the police automatically.Automatic alarm for infusion is by alarm lamp, alarm sound, set of cells, contact, spring, pull bar hook, circuit connection, switch, annular electro fishplate bar, plastics fixed block, shell etc. are formed up and down.

Suspension ring [1] are connected with shell [13], alarm lamp [2], alarm sound [3], set of cells [4] and upper contact [5] are installed in series in the last plastics fixed block [14] in shell [13], ring plate electricity fishplate bar [17] connects electric loop line [10], is fixed on the plastics fixed block [14] with hold-down screw [16].Pull bar hook [8] and the cover spring [7] outside of hanging transfusion bag [9] are contained in down in the interstitial hole of plastics fixed block [15], and adjusting sea whelk [6] is enclosed within pull bar hook [8] top and forms down contact [11]; On and off switch [12] is contained in down on the plastics fixed block [15], and following plastics fixed block [15] is connected with shell [13] by peripheral thread.

When the transfusion beginning, transfusion bag [9] to be hung on the pull bar hook [8] of automatic alarm for infusion, the gravity compression spring [7] of transfusion bag [9] makes down under the contact [11] and contracts, and breaks away from upper contact [5], and alarm circuit disconnects.When the medicinal liquid in the transfusion bag when being over, weight saving, under the elastic force effect of spring [7], pull bar hook [8] and contact [11] rising down, close with upper contact [5], alarm circuit is connected, and alarm lamp [2] is lighted, alarm sound [3] makes a noise rings, and calls out the nursing staff to remove transfusion or replacing transfusion bag.Beneficial effect

1, this utility model is simple in structure, esy to use, safe and reliable.The malpractice of having avoided transfusion blood to reflux and cause.

When 2, using this utility model transfusion, no longer must specially monitor transfusion with the entourage.
