Abstract
The utility model relates to an electric-heating apparatus for an infusion apparatus for vein injection. The utility model is composed of an electric heater, a temperature controller and a power supply of alternating-current/direct-current. The electric heater is composed of outer shells (2) and (3), an electric heating wire (6) and a heat conducting fin (8). When vein injection infusion is processed under the condition of lower air temperature and insufficient indoor heating, injection liquid medicine can be heated to 30-40DEG. C, and thus a patient's pain is reduced. The state of the decomposition of some liquid medicines caused by excess temperature caused by using a hot-water bag or a hot towel to heat can be avoided. Use is convenient and safe.
Description
This utility model relates to a kind of electric heater unit of intravenous injection and transfusion device.
Existing intravenous injection and transfusion device does not have heater.When winter temperature is lower, when indoor heating was not enough, the medicinal liquid and the blood of human body temperature difference were big.During transfusion, medicinal liquid makes the blood vessel of flowing through meet cold contraction to cause pain.Pain when reducing patient infusion, the method that adopts hot water bag or hot towel hot compress that medicinal liquid is heated up, this method makes the fluid temperature instability, when temperature is too high, some medicinal liquid is decomposed, and needs frequent the replacing when using, and is very inconvenient.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and when providing a kind of patient to infuse, can medicinal liquid be heated near human body temperature, reduces pain, the electric heater unit of intravenous injection and transfusion device easy to use.
The purpose of this utility model realizes by following measure:
This utility model (Fig. 1, Fig. 2, Fig. 3, Fig. 4) is a kind of electric heater unit of intravenous injection and transfusion device, and it is made up of electric heater, temperature controller and ac-dc dual power supply three parts.Its electric heater is made up of shell (2) (3), heating wire (6), insulating barrier (7) and conducting strip (8), lead (4).Shell (2) (3) but be two parts of symmetry folding, closing up its profile of back is that a rectangle box body is (or cylindrical, the elliptical cylinder-shape box body), shell (2) (3) connects with hinge (9), the opening and closing place is provided with hasp (1), heating wire (6), insulating barrier (7) and conducting strip (8) are made into two parts, be laid in respectively successively in the groove of shell (2) (3), after shell (2) (3) closes, two parts conducting strip (8) closes up, form the cylindrical space that equates with the medicinal liquid conduit external diameter of intravenous injection and transfusion device, temperature-sensitive element (5) is pressed on conducting strip (8), little hook hot pressing is made in shell (2) in two of conducting strip (8), (3) on, electric heater shell (2), (3) the end lead (4) of drawing is connected with temperature controller and ac-dc dual power supply.
Because the electric heater unit of this utility model transfusion device is when carrying out intravenous injection, liquid medicine injection is heated to body temperature near the people and temperature stabilization, be easy to control, thereby alleviate patient's pain and trouble, and can not make medicinal liquid Yin Wendu too high and decompose, it is quite convenient to use.
Drawing of the present utility model is described as follows:
Fig. 1 is the structure chart of electric heater of the electric heater device of this utility model intravenous injection and transfusion device.
Fig. 2 is that the figure A-A of electric heater structure of electric heater unit of this utility model intravenous injection and transfusion device is to the 3:1 profile.
Fig. 3 is the B part 3:1 enlarged drawing of electric heater structure chart of the electric heater unit of this utility model intravenous injection and transfusion device.
Among the figure:
The 1-hasp; 2,3-electric heater shell; The 4-lead; The 5-temperature-sensitive element; The 6-heating wire; The 7-insulating barrier; The 8-conducting strip; The 9-hinge;
Fig. 4 is the circuit theory diagrams of the electric heater unit of this utility model intravenous injection and transfusion device.
The utility model is described in further detail below in conjunction with drawings and Examples:
The shell of electric heater (2) (3), hasp (1) and hinge (9) are integral with plastic injection-moulded among this utility model embodiment.Conducting strip (8) is pressed on temperature-sensitive element, is beneficial to temperature sensor and changes.The little hook hot pressing at conducting strip (8) two is in the groove of shell (2), (3).Electric heater is long to be 110mm, and the synthetic cylindrical hole internal diameter of conducting strip (8) is φ 4mm, and the heating wire resistance is 10 Ω.For reducing the weight and volume of heater section, temperature controller and power supply are placed in the plastic casing together, the two links up with electric heater with segment length's lead (4).There is plug to connect the 220V alternating current on the plastic casing, also can connects low-voltage DC by socket.The two 8.5V voltages of transformator output, electric heater capacity is 7.2W.During use, electric heater is clipped in the part of transfusion device medicinal liquid conduit near drainage screen.Energized, display lamp is lighted, and electric heater begins medicinal liquid is heated up.Be warmed up to 40 ℃ nearly, the normally-closed contact of temperature controller repeat circuit disconnects, and cuts off the power supply in the heating wire, and display lamp extinguishes, and the temperature of heater and medicinal liquid begins to descend.When temperature nearly drops to 30 ℃, the normally-closed contact closure of temperature controller repeat circuit, the power connection in the heating wire, display lamp is lighted again, and electric heater begins again medicinal liquid is heated up.Carry out and so forth, reach intensification and temperature control purpose liquid medicine injection.Fluid temperature is raise and be controlled between 30-40 ℃, approaching with people's body temperature.
The utility model compared with prior art has following advantage:
1, the temperature of liquid medicine injection is heated to body temperature near the people, thereby alleviates patient's pain.
2, easy to use with electrical heating.
3, heating-up temperature is stable, is easy to control, and some soup is decomposed because of excess Temperature.
