Abstract
The utility model relates to a constant temp. infusion apparatus which is composed of a case, a cover, a panel, a circuit board, an electric heater and thermostat. Infusion device can be adjusted, and an adjusting button for positive and negative temperature, a temperature display, an electric source indicator, the work indicator of a heater, etc. are arranged on the panel. The utility model is especially supplied to hospitals and sanitation systems to be used for patients' constant temperature infusion.
Description
This utility model relates to the category of thermostat, particularly the constant-temp transfusion apparatus.
To patient infusion, it is the most common medical measure of health system treatment, when the transfusion temperature is lower than 10 ℃, patient often is afraid of cold, numb, or the sensation of pain, common way is that a section with tube for transfusion places one glass of hot water, temperature of liquid is risen to about 25 ℃, to remove patient's discomfort sensation, as China 2175615, patent name is: disposable constant temperature transfusion system (22 pages of world inventions magazine 2 phases of nineteen ninety-five) is exactly to utilize the temperature of human body to heat, also a kind of device that can heat with hot water, in this way Bu Fen solution patient infuse at low temperatures, problem does not feel like oneself, but this transfusion device clings to the body ice-cold transfusion device for old patient, can produce another discomfort, use hot water heating, easy really, but for the high temperature patient, or the obnubilation patient, must someone nurse, there is carelessness will cause the possibility of patient slightly with the hot water tipping.And the technology of thermostat is very ripe, is utilized in every field by people already, also this technology can be applied in the transfusion and go.
The design the purpose of this utility model provides a kind of, and by electronically controlled, the constant-temp transfusion device that can be regulated by electrically heated temperature is to remove the discomfort of patient in infusion process.
This utility model is by following structure, achieve the goal, this utility model is made up of parts such as box, lid, circuit board, control panel, electric heater, heat mediums, it is characterized in that in box, being equipped with wiring board, electric heater by heat medium to the transfusion heating, and be provided with temperature controller, when transfusion was higher than a certain temperature, power supply cut off automatically, can connect heater circuit automatically again when being lower than a certain temperature.
Accompanying drawing 1 is the outline drawing of constant temperature transfusion system, and accompanying drawing 2 is profiles of constant temperature transfusion system, and accompanying drawing 3 is electrical schematic diagrams of thermostat, below in conjunction with accompanying drawing this utility model is done further to describe.
Woven hose 1,7 places the centre of box 12 and lid 11, is provided with in a side of box Supply hub 8, power supply indicator 9, heater work indication 10 is on panel 14 Be provided with temperature and show 6, negative temperature regulates 5, positive adjustment 4, and power switch 3, The top of box also is provided with pendant 2, in order to constant temperature transfusion system is suspended on infusion support On, in the box 12, also be provided with wiring board 13, electric heater 18 heat mediums 17, The inside of lid 11 is filled with insulation material 15.
The utility model provides electric energy by low-tension supply, thereby has guaranteed the safety of using, Fig. 3 is its electrical schematic diagram, and its feature is by R1, and the D1 series connection inserts in the low-voltage circuit, forms Power supply indication, by R2, D2 is composed in series the work indication of heater, filter capacitor C with Integrated package of pressure-stabilizing 7805 consists of the temperature controller power supply, and temperature controller is connected with relay J, is connected on In the circuit, temperature controller adopts presses the temperature controller that key (4), (5) are controlled gradient of temperature.
This utility model compared with prior art has tangible advantage.Temperature controller, electric heater technology are very ripe, can use in the constant temperature transfusion system safely and reliably fully and go, and the transfusion temperature is adjustable, is applicable to different temperature, low-voltage power supply, and is safe and reliable.The solution that this utility model is more satisfactory the transfusion temperature low excessively, cause the uncomfortable problem of patient.
Further this utility model is further described with embodiment below, if use the transfusion personnel many at the large hospital transfusion room, on the sick bed next door low-voltage circuit and socket are installed in advance, as in scale than subsection, the few out-patient department of transfusion patient uses, can be at the 8-12V that buys a ready-made band plug on the market, 5W power supply (using power supply for recorder) utilizes civil power alternating current 220V power supply.Connect the power supply opening switch during use earlier, and notice whether power supply indicator is bright, constant temperature transfusion system is suspended on the drip stand, the attemperation lifting button shows a proper temperature on display, open the lid, sandwich tube for transfusion, build lid, it is shinny to notice that heating work indicates whether, can carry out constant-temp transfusion after two minutes.
