Abstract
The utility model discloses a constant temp transfusion system, mainly composed of a transfusion pipe (2), an insulating hood (1) and a base (5). The insulating hood (1) is connected with the base (5), and a reservoir (3) communicated with the transfusion pipe (2) is arranged between the insulating hood (1) and a heat storing block (4). A PTC electric heater (6) is arranged between the heat storing block (4) and the base (5) and is appressed with the heat storing block (4), and the PTC electric heater (6) is connected with a power supply by a plug (10). The utility model can carry out the temp limited heating to liquid medicine (7). So the utility model has the advantage of convenient operation and is particularly suitable for use in low temperature season and cold area. The utility model can avoid the paradoxical reactions of ague and chill of the patient caused by the low temperature liquid medicine.
Description
This utility model relates to a kind of constant temperature transfusion system that can limit temperature heating medicinal liquid, especially limits the constant temperature transfusion system of temperature heating with the PTC heater element.
In the clinical treatment work, infusion treatment is the Therapeutic Method of using always.But,, more obvious by abnormal response, particularly infant and person worn with age that transfusion person often feels cold, shivers with cold in temperature lower season and area.The reason that takes place, except that quilt transfusion person body constitution difference, the fluid temperature of main the is defeated person is too low.
The purpose of this utility model provides a kind of easy to use, the constant temperature transfusion system that can limit temperature heating.This constant temperature transfusion system has electric heater.Electric heater is powered by external power supply.
For achieving the above object, the technical solution adopted in the utility model is: constant temperature transfusion system mainly is made up of tube for transfusion, thermal insulation cover, base.Thermal insulation cover and base are for flexibly connecting.Tube for transfusion places between thermal insulation cover and the base, and is communicated with the reservoir between thermal insulation cover and the base.Reservoir is placed on the heat accumulation piece.Between heat accumulation piece and base, be close to an energising of installation rear surface, heat accumulation piece bottom surface temperature and be not more than 70 ℃ PTC electric heater.Thermal insulation cover, base, tube for transfusion, reservoir are made of metal of metal or plastic production, heat accumulation piece.Power supply is civilian alternating current.Employed heater element has positive temperature coefficient in the technical solution adopted in the utility model, i.e. ptc characteristics.Under the situation of energized, PTC element self temperature raises.When temperature reached the element curie point, the resistance value of this element sharply increased, and component temperature no longer raises.Utilize this characteristic, just can limit the temperature heating heated object.
After adopting such structure, this kind transfusion device bottom is equipped with the PTC electric heater, after energized, the heat that electric heater sends gathers heat by the heat accumulation piece, the reservoir and the medicinal liquid of containing are heated to predetermined temperature and keep constant temperature, and homothermic medicinal liquid flow to the infusion needle injection by in transfusion person's body from the tube for transfusion of the reservoir port of export.Solved by the low excessively problem of transfusion person institute loading liquid temp, avoided feeling cold, chill reaction, easy to use.Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is the cutaway view of a specific embodiment of constant temperature transfusion system of the present utility model;
Fig. 2 is the circuit diagram of a specific embodiment of constant temperature transfusion system of the present utility model.
Constant temperature transfusion system shown in Figure 1 is made up of tube for transfusion (2), thermal insulation cover (1), base (5); Thermal insulation cover (1) is the hinge type combination with base (5), and closes fixing by the trip pass.Tube for transfusion (2) is by being communicated with between thermal insulation cover (1) and the base (5) and with reservoir (3), and a heat accumulation piece (4) is arranged at reservoir (3) bottom, is close to heat accumulation piece (4) bottom surface between heat accumulation piece (4) and base (5) bottom surface electric heater (6) is installed.Heat accumulation piece (4), electric heater (6), base (5) connect with screw (8).Electric heater (6) connecting line is drawn from the lateral hole of base (5), and by attaching plug (9) energized.Reservoir (3) cross section is a rectangle, and heat accumulation piece (4) upper surface has a groove, and the tube for transfusion (2) that is communicated with reservoir (3) two ends is not or not same plane, and high-end is liquid feeding end, and low side is a liquid outlet.This constant temperature transfusion system profile is a cuboid.
Circuit shown in Figure 2 is formed by connecting by PTC heater element R and lead.When plug (9) inserts supply socket, a, b termination energize, the PTC heater element is with regard to the evolution of heat and steady temperature heating reservoir (3) medicinal liquid of containing.
During use, attaching plug (9) is inserted supply socket, the joint of disposable transfusion device transfusion needle one end is unpluged, and the tube for transfusion (2) of disinfectant reservoir (3) liquid feeding end is communicated with the disposable transfusion device liquid outlet again, and the tube for transfusion (2) of reservoir (3) liquid outlet is communicated with transfusion needle.Feed liquor pin and air needle with disposable transfusion device pierce through the infusion bottle plug that fills medicinal liquid, the reversing infusion bottle, and its bottleneck is downward.Infusion bottle is hung up drip stand, and transfusion capsule (3) and transfusion needle are put in the position that is lower than infusion bottle, utilize atm difference, make the tube for transfusion of disposable transfusion device, the reservoir of constant temperature transfusion system (3) to transfusion needle be full of medicinal liquid (7), close transfuse switch.The reservoir (3) that will be full of medicinal liquid (7) is put in heat accumulation piece (4) groove, covers thermal insulation cover (1).Thrust a little at the selected on one's body transfusion needle of quilt transfusion person, the sterilization local skin thrusts its skin and vein blood vessel with transfusion needle, opens the transfuse switch of disposable transfusion device, regulates drip velocity.At this moment, by transfusion person institute loading liquid temp promptly near body temperature.
Certainly, the profile of constant temperature transfusion system and reservoir (3) can also be made other shapes, and also available other modes in each coupling part connect.Electric heater (6) also can use other heated at constant temperature elements.Also available other low-voltage alternating current power supplies of power supply or dc source.These conversion all drop within the protection domain of the present utility model.
Claims (5)
1, a kind of constant temperature transfusion system is made up of tube for transfusion (2), thermal insulation cover (1), base (5); Thermal insulation cover (1) is flexible connection with base (5); Tube for transfusion (2) places between thermal insulation cover (1) and the base (5); It is characterized in that: tube for transfusion (2) is by being communicated with between thermal insulation cover (1) and the base (5) and with reservoir (3), there is a heat accumulation piece (4) in reservoir (3) bottom, and being close to heat accumulation piece (4) bottom surface between heat accumulation piece (4) and the base (5) has an energising rear surface temperature to be not more than 70 ℃ electric heater (6).
