Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, a kind of specifically infusion alarm.
Background technology:
At present, transfusion is very important means in the medical treatment, when one bottle of medicine is totally lost, should in time syringe needle be pulled out, otherwise occur easily in the air admission blood, jeopardize people's phenomenons such as life, there is the defective that design is comparatively complicated, price is more expensive in existing infusion alarm more, and time of fire alarming fixes, and can not regulate according to the size of medicine bottle, the medicine bottle that only adapts to certain dose has limited the application of infusion alarm.
Summary of the invention:
The purpose of this utility model is to overcome existing infusion alarm time of fire alarming and fixes, and the defective that design is comparatively complicated, price is more expensive, design a kind of simple in structure, with low cost, power consumption is few and can report to the police when how many doses of residue according to the size of medicine bottle or needs, regulates the time of fire alarming of infusion alarm easily.
The technical scheme that this utility model provides is:
Infusion alarm, its shell inner bottom part is fixed a cylinder, and a spring is arranged in the cylinder, and the spring upper end connects contact chip, contact chip bottom cylinder lever connecting rod hook, the pull bar hook passes spring and reaches outside the shell, and the cylinder top installs and fixes dish, fixes a nut shape on the fixed disk and connects electroplax, set of cells one utmost point is connected with electric wire with buzzer, buzzer connects contact chip, and another utmost point of set of cells connects switch, and switch attaching nut shape connects electroplax.
Concrete, nut shape connects electroplax and is provided with adjusting rod, and shell is stretched out in the adjusting rod upper end, and the lower end is relative with the contact chip locus.Preferably, nut shape connects electroplax and adjusting rod is a threaded engagement.
Shell is provided with lifting rope.
Adjusting rod be positioned at contact chip directly over, adjusting rod can move up and down according to demand, and adjusting rod and contact chip position contacting are changed, thereby changes the time of fire alarming of alarm.Wherein nut shape connect electroplax, adjusting rod and contact chip by electric conductivity preferably material make.
The center that the shell of this alarm, cylinder, spring, contact chip, pull bar hook, nut shape connect electroplax, adjusting rod point-blank, keep vertical state when making alarm work, reduce unnecessary collision, friction between the parts, the accuracy and the service life of improving alarm.
During use, infusion alarm utilizes lifting rope to be suspended on the drip stand, after medicine bottle is suspended on the pull bar hook, opens switch, because the effect of gravity, contact chip is to the lower compression spring, and contact chip breaks away from adjusting rod, along with the minimizing of liquid medicine, contact moves upward gradually, when contact chip contact adjusting rod, circuit loop is connected, buzzer warning.。
This utility model is simple in structure, and is easy to use, with low cost, and power consumption is few, lasting and can regulate time of fire alarming to be suitable for the medicine bottle with Different Weight according to practical situation.

The specific embodiment
Describe this utility model in detail below in conjunction with accompanying drawing:
A kind of infusion alarm, shell 4 is provided with lifting rope 6.Shell 4 inner bottom parts are fixed a cylinder 8, one spring 11 is arranged in the cylinder 8, spring 11 lower ends connect shell 4 bottoms, the upper end connects contact chip 9, because the restriction of cylinder 8, contact chip 9 is stretching motion up and down, a pull bar hook 12 is fixed in the center of contact chip 9 bottoms, the hook of pull bar hook 12 passes spring 11 and shell 4 bottom centre's apertures stretch out shell 4, is used for hanging medicine bottle, and contact chip 9 is connected with buzzer 10 usefulness electric wires.One utmost point of set of cells 1 connects buzzer 10 with electric wire, and another utmost point then connects switch 2, and switch 2 attaching nut's shapes connect electroplax 3.
The superjacent air space of cylinder 8 is equipped with fixed disk 7, and hold-down nut shape connects electroplax 3 on the fixed disk 7, and nut shape connects electroplax 3 centers screw and adjusting rod 5 threaded engagement work, and rotation adjusting rod 5 can make adjusting rod 5 move up and down.
It all is to adopt the good material of electric conductivity that nut shape connects electroplax 3, adjusting rod 5 and contact chip 9.
The center that the shell 4 of this alarm, cylinder 8, spring 11, contact chip 9, pull bar hook 12, nut shape connect electroplax 3, adjusting rod 5 point-blank.
During use, infusion alarm utilizes lifting rope 6 to be suspended on the drip stand, after medicine bottle is suspended on the pull bar hook 12, opens switch, because the effect of gravity, contact chip 9 is to lower compression spring 11, and contact chip 9 breaks away from adjusting rod 5, along with the minimizing of liquid medicine, contact chip 9 moves upward gradually, when contact chip 9 contact adjusting rods 5, circuit loop is connected, and buzzer 11 is reported to the police.Because adjusting rod 5 can move up and down, the adjusting rod 5 and the contact position of contact chip can be changed, thereby change time of fire alarming, when using for the first time, at first rotate adjusting rod 5 to determine time of fire alarming, have only later on when needs conversion time of fire alarming or just need rotate adjusting rod 5 to change time of fire alarming when changing vial size.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment this utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that this utility model asks for protection.
