Description

The transfusion device alarm device

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of transfusion device with warning function.

Background technology

Existing transfusion device has a probe that has liquid outlet and air inlet, and this probe thrusts in the medicated bag and by tube for transfusion and syringe needle medicament injected in patient's body then.In infusion process and when finishing, due to illness sleeping the or entourage of people does not note causing easily and stops dripping or cause phenomenons such as input air, blood back to take place, and causes unnecessary misery to patient.

Summary of the invention

This utility model is exactly in order to address the above problem, and a kind of acousto-optic and wireless signal that can in time send warning when transfusion is finished is provided, and notifies medical personnel in time to carry out the transfusion device of relevant treatment, and it has simple in structure, and is easy to use, the advantage of safety and sanitation.

This utility model has adopted following technical scheme for achieving the above object: a kind of transfusion device alarm device, liquid outlet and air inlet that it will have the transfusion device probe now improve, it is characterized in that: floated switching device is arranged respectively in liquid outlet and air inlet, and they connect with alarm device by lead.Described floated alarm device is, both sides, bottom at liquid outlet and air inlet, a pair of corresponding lead is respectively arranged, every pair of lead upper end all is that the symmetric tube wall that penetrates liquid outlet and air inlet along same horizontal line forms a pair of discontiguous contact, lower end edge probe outer wall and its handle holder are adhered to, and connect with respective wire; Upper end at liquid outlet and air inlet has a limited block respectively, is a suspension piece between contact and limited block, and its width matches with gap size between the contact, and itself and contacted position, contact have conductive material.

At least one perforate that penetrates tube wall is arranged below the contact in the described liquid outlet.

Described alarm is an audible-visual annunciator, and it has the delay circuit of the anti-error energy of reporting achievement, and contact switch.

Described warning utensil also has radio alarming circuit and receptor, can realize radio alarming.

This utility model is provided with the suspension switch block in the liquid outlet of transfusion device probe and air inlet, after probe thrusts medicinal fluid bag, medicinal liquid enters liquid outlet, the suspension piece is at liquid buoyancy effect float downward, limited block by liquid outlet top blocks, medicinal liquid flows out along liquid outlet, impacting the suspension piece when preventing that medicinal liquid from flowing down makes it and does not contact the contact and contact, simultaneously do not contacting 1-2 the perforate that penetrates tube wall under the contact in addition, this perforate enters in the medicinal fluid bag in the lump in company with probe, and medicinal liquid also can flow out from this perforate, so just can not make the suspension piece be subjected to too big impulsive force, also be convenient to simultaneously the outflow of residue medicinal liquid in the medicinal fluid bag, avoided waste.Do not contact the contact and be have a pair of along both sides, liquid outlet bottom on same horizontal line symmetry penetrate that the lead of hole wall forms, after the other end of lead adheres to along probe outer wall and its handle holder, device taking alarm.When medicinal liquid is totally lost, there is not liquid in the liquid outlet, the suspension piece falls in the effect of own wt and does not contact between the contact, thereby make circuit turn-on, alarm equipment alarm, alarm can send optical signal when reporting to the police, and carry out music alarm or audio alert, this alarm price is low, and technology is simple, is suitable for family transfusion or small-sized outpatient service transfusion and is suitable for; Alarm also can be equipped with wireless transmitter, form wireless alarm system with the receptor of ward or nurse's body band, when alarm equipment alarm is sent electric wave, the receptor signal of sounding shows the sick bed number simultaneously, the prompting operator on duty, make patient, family members, medical personnel can in time understand the transfusion situation, accurately and timely handle relevant situation, improve the medical treatment level of hospital, emitter wherein and receptor adopt known equipment.The position that does not contact the contact can be installed on the probe according to actual needs, to reserve a period of time wait nurse's arrival.

Identical in suspension switching device structure in the air inlet and the liquid outlet, it is to utilize in the air inlet buoyancy of gas that the suspension hole is floated to leave not contact the contact, no longer including gas after medicinal liquid is totally lost enters in the medicated bag, the suspension piece falls in the own wt effect and does not contact between the contact, make circuit connect alarm work.For avoiding wrong report occurring because of the air-flow instability causes suspension piece and contact frequently to contact, alarm has delay circuit, can delay time 5-10 second.For preventing that alarm device and medicinal liquid from reacting, the suspension piece that is suitable for should with the plastics homogeneity of probe, lead should with the infusion needle homogeneity.By above-mentioned analysis, the beneficial effect that the utlity model has as can be known is: simple in structure, after transfusion is finished, can in time report to the police by acousto-optic and wireless signal, effectively having avoided transfusion to finish after the problem of blood back or input air, alleviated patient's misery.

The specific embodiment

Structure of the present utility model as shown in Figure 1 and Figure 2, liquid outlet 2 and air inlet 3 on the probe 1, be distributed with couple of conductor 8 in liquid outlet 2 bottom lateral symmetry, the one end penetrates hole wall and forms a pair of contact 4 that do not contact on same horizontal line, the tight probe of the other end of lead 81 outer wall adheres to the back with the handle holder and connects with alarm 5.One limited block 6 is arranged in the upper end of liquid outlet 2, it can be a tinsel or the plastics bolt that crosses in the hole, not contacting 6 of contact 4 and limited blocks is suspension piece 7, it can be bar-shaped or spherical, its width matches with the gap size that does not contact 4 of contacts, with the place that does not contact contact 4 connections conductive material is arranged, the below that does not contact contact 4 on the liquid outlet 2 penetrates 1-2 perforate 9 of tube wall in addition, as shown in Figure 2.

Floated switching device in the air inlet 3 does not have the perforate 9 except that not contacting 4 belows, contact, and all the other structures are identical with floated switching device structure in the liquid outlet 2, as shown in Figure 1, do not repeat them here.

The structure of alarm 5 has light emitting diode and contact switch as shown in Figure 3 on it.The delay circuit that links to each other with the floated switching device of air inlet 3 in alarm 5 simultaneously can carry out 5-10 with ining addition delays time second, causes suspension piece 7 and does not contact contact 4 and frequently contact and report by mistake because of the air-flow shakiness preventing.
