Abstract
An alarm device for an infusion apparatus comprises an air bag, a sliding groove and a metal slider, the air bag is arranged in a dropper of the infusion apparatus, the sliding groove is communicatedwith the air bag, the metal slider is arranged in the sliding groove, and a far-end electrode and a near-end electrode are also arranged on the wall of the sliding groove, and are connected with a power supply and an alarm unit to form a circuit. The far end of the sliding groove is also provided with an air valve switch. Because the alarm device is arranged outside the dropper of the infusion apparatus, the alarm circuit is not directly contacted with the infusion, and thereby the hygienic standard is guaranteed; the air pressure of the alarm device can be regulated, regulation is accurate, and thereby an optimal alarm effect is ensured; and the alarm device has the advantages of simple structure arrangement, low cost, convenient use, good effect and easy popularization.
Description
Technical field
This utility model relates to a kind of medical transfusion equipment, is specifically related to a kind of transfusion device alarm device.
Background technology
Present transfusion device when infusing to patient, when transfusion is finished soon, needs patient's nursing staff to help to remind, and pulls out pin by the nurse.And patient or accompany and attend in case absent-minded or do not note observing delays the opportunity of pulling out pin or changing pin sometimes, causes suffering or even danger to patient.
Notification number: CN2850622, the Chinese patent literature of the day for announcing: 2006.12.27 has been announced " transfusion device alarm device ", it has solved present patient after transfusion is finished, can not in time find to cause blood back or input air, cause the problem of unnecessary misery to the patient, have simple in structure, the advantage that can behind the liquid of being totally lost, in time report to the police, its structure is: it has the transfusion device probe of drag-out hole and air inlet, 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.But this utility model exists mechanism complexity is set by floated switch is set, the cost height, and it is inaccurate to report to the police, and uses problems such as not enough health.
Summary of the invention
The purpose of this utility model is at existing transfusion device alarm device structure complexity to be set, the cost height, and it is inaccurate to report to the police, and uses deficiencies such as not enough health, provides a kind of structure to be provided with simply, and cost is low, reports to the police accurately, uses a kind of transfusion device alarm device of health.
The purpose of this utility model realizes by following technological means: the transfusion device alarm device, include and be arranged on transfusion device and drip air bag in the kettle, with sliding tray that is communicated with setting with air bag and sliding metal piece wherein, also be provided with remote electrode and proximal electrode on the sliding groove wall, remote electrode and proximal electrode are communicated with power supply and alarm device is formed a circuit loop.
The far-end of described sliding tray also is provided with an air valve switch.
Described sliding metal piece is set to the structure of hollow.
Described alarm device is set to voice guard and flash alarm is arranged in parallel.
Described remote electrode and proximal electrode are set to becket or sheet metal in sliding tray inside, and the sliding tray outer setting has binding post.
Compared with prior art the utlity model has following tangible advantage: 1, this transfusion device alarm device is arranged on the outside that transfusion device drips kettle, and warning circuit does not directly contact with the liquid of transfusion, has guaranteed sanitary standard.2, this transfusion device alarm device, air pressure is adjustable, regulates accurately, has guaranteed the warning best resultsization.3, this transfusion device alarm device structure is provided with simply, cost is low, easy to use, effective, is very easy to promote.
Description of drawings
Fig. 1 is a cross section structure sketch map of the present utility model;
Fig. 2 is the circuit diagram of utility model;
Among the figure, 1-air valve switch, 2-sliding metal piece, 3-air bag, DC-power supply, k-switch, a-remote electrode, b-proximal electrode, m-alarm device.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment this utility model is described in further detail: as shown in Figure 1, the transfusion device alarm device, include and be arranged on transfusion device and drip air bag 3 in the kettle, with sliding tray that is communicated with setting with air bag 3 and sliding metal piece 2 wherein, also be provided with remote electrode a and proximal electrode b on the sliding groove wall, remote electrode a and proximal electrode b are communicated with power supply DC and alarm device m forms a circuit loop.Described remote electrode a and proximal electrode b are set to becket or sheet metal in sliding tray inside, and the sliding tray outer setting has binding post.Such setting, in transfusion device drips kettle, drip when liquid is arranged, the pressure of liquid is greater than the pressure in the air bag 3, to promote sliding metal piece 2 to direction motion away from air bag 3, thereby disconnect being connected of remote electrode a and proximal electrode b, just disconnected switch k as shown in Figure 2, thereby made circuit for off-state.When dripping of transfusion device do not have transfusion liquid in the kettle, pressure in the air bag 3 will be greater than the pressure in the kettle of transfusion device, thereby promote sliding metal piece 2 to direction motion near air bag 3, thereby connected being connected of remote electrode a and proximal electrode b, just connected switch k as shown in Figure 2, thereby make circuit for "on" position, alarm device m starts working, and patient and medical personnel are carried out warning reminding.The far-end of described sliding tray also is provided with an air valve switch 1.The setting of air valve switch 1, can accurately adjust the position of sliding metal piece 2, by input gas or extracting gases in the space of sliding tray and air bag 3, change its inner air pressure, thereby select the exact position of suitable disconnection or connection remote electrode a and proximal electrode b.This transfusion device alarm device is arranged on the outside that transfusion device drips kettle, and warning circuit does not directly contact with the liquid of transfusion, has guaranteed sanitary standard.In addition, this transfusion device alarm device, air pressure is adjustable, regulates accurately, has guaranteed the warning best resultsization.
Described sliding metal piece 2 is set to the structure of hollow.Like this, can alleviate the weight of this transfusion device alarm device and improve the handling of this transfusion device alarm device, save operation and manufacturing cost.
Described alarm device m is set to voice guard and flash alarm is arranged in parallel.Like this, patient can select suitable alarm to carry out better warning reminding.
In a word, this transfusion device alarm device structure is provided with simply, cost is low, easy to use, effective, is very easy to promote.
