Detailed description of the invention
With reference to the accompanying drawings embodiment of the present utility model is described in detail below:
As Fig. 1, 2, shown in 3, a kind of disposable transfusion device with heating function, it is characterized in that: comprise bottle plug puncture unit (1), air inlet pipe air filter (2), drip kettle (3), infusion tube (4), flow regulator (5), PTC heater (6), intravenous needle (7), helmet (8), wherein PTC heater (6) comprises ptc heater (9), power line (10), power interface (11), ptc heater (9) is by PTC thermal sensitive ceramics element layer (12), aluminum heat dissipating layer (13), heat-insulation layer (14), injection casing (15) composition, described a kind of disposable transfusion device with heating function, its structure is followed successively by bottle plug puncture unit (1), drip kettle (3), flow regulator (5), PTC heater (6), intravenous needle (7), all parts are connected by infusion tube (4).
Described air inlet pipe air filter (2) in the one end identical with bottle plug puncture unit (1) of the disposable transfusion device with heating function, the infusion tube connected (4) and air inlet pipe air filter (2) and bottle plug puncture unit (1) is Y-shaped is connected.
Described PTC heater (6) comprises ptc heater (9), power line (10), power interface (11), power line (10) one is connected with PTC thermal sensitive ceramics element layer (12), and other end is connected with power interface (11).Power interface (11) can be multiple interfaces mode, as USB interface, DC interface etc.
Described ptc heater is made up of PTC thermal sensitive ceramics element layer (12), aluminum heat dissipating layer (13), heat-insulation layer (14), an injection casing (15).Its arrangement mode as shown in Figure 3.
A described injection casing (15) is rectangle or column type is arranged.
Described helmet (8) is for the protection of intravenous needle (7).
The arcuation PTC element that described PTC thermal sensitive ceramics element layer (12) adopts under low pressure can carry out the PTC heating element heater of high temperature exothermic by 3.7-7.4V.
This utility model is when normally working, liquid originally has a transfusion device of heating function from medicinal glass bottle through bottle plug puncture unit (1) inflow, liquid to enter before PTC heater (6) and flow through the same with common disposable transfusion device drips kettle (3), flow regulator (5) and an intravenous needle (7) afterwards, enters human body from intravenous needle (7).
When liquid enters PTC heater (6), ptc heater (9) can heat liquid.The work process of PTC heater (6) is: power supply connects external power supply by power interface (11), is connected into ptc heater (9) via power line (10).
During normal work, PTC thermal sensitive ceramics element layer (12) generates heat, and transfers heat to the liquid flowed through, thus the temperature of the liquid flowed through is raised rapidly by aluminum heat dissipating layer (13).Heat-insulation layer (14) plays the effect of insulation, and thermal conversion efficiency is improved.
In use, when the temperature of medicinal liquid is about to arrive 35-38 DEG C, the resistance value of PTC thermal sensitive ceramics element layer (12) sharply increases 10
4doubly left and right, only with weak current maintenance heat balance, PTC heater (6) is in the duty that energy-saving constant-temperature keeps.Ptc heater (9) Automatic Control temperature, the output of ptc heater (9) progressively reduces along with the rising of temperature, energy-conservation highly significant.Be in the duty automatically adjusting heating power with variation of ambient temperature eventually, give full play to the power savings advantages that temperature memory intellectual material is temperature automatically controlled with the change of ambient temperature, vary with temperature adjustment heating power.This utility model is prior art low, easy to use, the simple feature that possesses cost comparatively.Meet low pressure or battery powered simultaneously, meet the job requirement of armarium low-voltage.
For the full bottle ejection situation of conventional 500ml infusion bottle, transfusion caliber Φ 3.5-4mm, one piece of output voltage 7.4V, capacity are the lithium battery energy continuous heating 1 bottle of 2.6Ah, flow velocity 50-90 drip/minute condition under, make liquid can reach about 27-33 DEG C when entering in body.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to this utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
