Description

A kind of universal automatic alarm for transfusion

Technical field

This utility model belongs to technical field of medical instruments, is particularly a kind ofly implementing the autoalarm of intravenous injection when complete.

Background technology

A kind of important conventional treatments when intravenous injection is clinical treatment, because of this process duration longer, and each individuality causes inject time different because of the injection speed difference, needing to change medicinal liquid or finishing injection just needs entourage and medical and nursing work person to pay close attention to, this has increased medical and nursing work person's work load on the one hand, causes unnecessary mental pressure and has further increased again medical personnel's work load because the entourage judges different this on opportunity that needs to change medicinal liquid or finish injection to the patient.Cause easily in patient's blood back or the tube for transfusion and be filled with air etc. because can not in time changing medicinal liquid or finishing injection, may cause malpractice to occur when serious.Especially, when the groupment medical treatment occured, medical personnel were short, phenomenon tired out is serious, more were necessary to alleviate medical personnel's labor intensity by technological means.Patent 200520078480.X discloses a kind of automatic alarm for infusion, and it comprises housing and is installed in a cover voice circuit of casing upper half.A T-shaped suspension rod of metal is arranged in the latter half housing, and cover has a ring spring on this suspension rod, hangs the centre bore that club head stretches out the housing bottom end cover.As a kind of improvement, tube wall at the latter half housing has two corresponding vertical grooves, and at the outer wall of bottom shelf half cover a screw shell is arranged, helicla flute corresponding to twice arranged on the screw shell inwall, the direct through groove on the housing is passed in two terminations of the round key of two electrical contact lifting positions in the control sound circuit, and is embedded in the corresponding helicla flute.When the medicine bottle dose on the above-mentioned alarm that hangs was gradually reduced to minimum limiting the quantity of, sound circuit was switched on, and signal gives the alarm.In this patent, although can adjust by the dose specification that hangs the high and low position of two electrical contacts in the sound circuit, but need rotary manipulation when needing to change the infusion bottle of different size in practical operation, the exchange bottle causes very big inconvenience like this, runs counter to the invention original intention.Patent 20092007233.9 discloses a kind of infusion alarm, and it is simple in structure, volume is little can to the effective monitoring of transfusion process, in time send chimes of doom when transfusion is finished.But this invention can not adapt to the transfusion of plurality of specifications, can only tackle specific standard, has greatly limited the practical suitability of this patent.

Summary of the invention

This utility model provides a kind of autoalarm for the deficiencies in the prior art, is particularly a kind ofly implementing the autoalarm of intravenous injection when complete.In order to realize the versatility to existing injection specification, the present invention adopts the gravity carry to change the principle that causes spring position to change, this universal automatic alarm for transfusion includes hook, overcoat, is provided with a spring housing in the overcoat on the motion bar with hook.The motion bar upper end is UNICOM's bar fixedly, motion bar and the simultaneously upper and lower motion of UNICOM's bar.Relatively have chute on the inwall of overcoat, relatively be provided with the transfusion bag binding post in the chute from top to bottom, 100ml infusion bottle binding post, 250ml infusion bottle binding post, and 500ml infusion bottle binding post.UNICOM's bar is provided with contact flat spring, and on UNICOM's bar and the two ends of contact flat spring are arranged in the chute, and contact flat spring can upper and lower slip in chute.The outer wall of said overcoat is provided with gear on-off.Every group of relatively every pair of wire connection terminals of switch in the gear on-off, and be connected in the warning circuit.The warning circuit of being furnished with battery, warning light, loudspeaker is positioned at overcoat 3 tops.

This utility model is realized the general of different size infusion bottle and transfusion bag by simple structure; Alleviate caregiver

Member's labor intensity alleviates patient and entourage's mental burden; Safe, reliable, economical, be beneficial to and use on a large scale and promote; Do not pollute medicinal liquid, can realize the quick-setting when the different size medicine bottle is changed dressings.

The specific embodiment

Below in conjunction with embodiment this utility model is described further, but is not limited to this.

With reference to accompanying drawing, this universal automatic alarm for transfusion includes hook 17, overcoat 3, is provided with a spring 4 in the overcoat 3 and is enclosed within on hook 6 the motion bar 5.Motion bar 5 upper ends are UNICOM's bar 1 fixedly, motion bar 5 and simultaneously upper and lower motion of UNICOM's bar 1.Relatively have chute 7 on the inwall of overcoat 3, relatively be provided with transfusion bag binding post 8 in the chute 7 from top to bottom, 100ml infusion bottle binding post 9,250ml infusion bottle binding post 10, and 500ml infusion bottle binding post 11.UNICOM's bar 1 is provided with contact flat spring 2, and on UNICOM's bar 1 and two ends of contact flat spring 2 are arranged in the chute 7, and contact flat spring 2 can be in chute 7 interior upper and lower slips.The outer wall of said overcoat 3 is provided with gear on-off 12.The relatively every pair of wire connection terminals of gear on-off 12 interior every group of switches, and be connected in the warning circuit 13.The warning circuit 13 of being furnished with battery 14, warning light 15, loudspeaker 16 is positioned at overcoat 3 tops.

Work process of the present utility model is as follows:

When on the hook 6 when carry infusion bottle or transfusion bag under action of gravity, spring 4 is subjected to gravity compressed, along with transfusion is carried out, gravity reduces, spring is resilience gradually.In sleeve side wall 3 inwall chutes 7, be provided with the fourth gear contact chip, distinguish from top to bottom corresponding transfusion bag binding post 8,100ml infusion bottle binding post 9,250ml infusion bottle binding post 10 and 500ml infusion bottle binding post 11, contact flat spring 2 positions on transfusion is near when finishing corresponding motion bar 5 first line of a couplet through rods 1, wherein transfusion bag is little because of the bag deadweight, so the transfusion bag of 100ml, 250ml, 500ml is corresponding same binding post 8 positions all, can be implemented in transfusion and approaching and finish alarm.Infusion bottle is larger because of bottle deadweight difference, so corresponding three gears are put respectively, contact is reported to the police respectively.The warning circuit of being furnished with battery, warning light, loudspeaker is positioned at overcoat 3 tops.Wherein gear on-off is four independent folding switches.When for example injecting separately one bottle of 500ml medicinal liquid, the 500ml that gear on-off is corresponding is in closure, then contact by two contact chips in the internal chute 7 on the contact flat spring 2 on UNICOM's bar 1 and overcoat 3 sidewalls when complete in that injection is near, make circuit turn-on, the warning circuit warning.When needs were changed other specifications, the specification place switch that gear on-off is corresponding was beaten to closure state and is got final product first.
