Abstract
The utility model relates to a warmer for intravenous infusion, comprising a backing, an electrothermic core, a power socket, a heat-insulating layer, a disinfecting sleeve, a lacing. The utility model can carry out liquid warm of intravenous infusion, which provides the sense of comfort and safety, reducing or avoiding infusion reaction which possibly happens in the process of the infusion of patients.
Description
Venous transfusion warmer of the present utility model relates to a kind of electric-heating technology.
Medical personnel often carry out the venous transfusion therapy to patient clinically.But occur serious complication such as infusion reaction in infusion process sometimes, wherein a part of patient's infusion reaction is because the temperature of liquid of input and human body temperature differ too greatly and cause.Especially old, weak, child, patients such as (ante cibum) on an empty stomach, the low excessively liquid of the big amount temperature of input under the lower situation of ambient temperature, fear of cold occurs easilier, shiver, symptom such as hyperpyrexia, need take to stop transfusion and other emergency measures, severe patient or rescue improper can causing death.In the past, the method for prevention taked hot water bag to heat, add a cover warming, the transfusion speed etc. that slows down of cotton-wadded quilt more, but was to use inconvenience, effect undesirable, did not still have special device so far.
This utility model aims to provide a kind of venous transfusion warmer.It can be heated to venous transfusion time institute transfusion, makes patient that comfort, the security be arranged, and reduces or avoids patient's contingent infusion reaction in infusion process.
The purpose of this utility model is achieved in that
The venous transfusion warmer is made up of substrate, heating core, supply socket, heat-insulation layer, sterilizing covers, frenulum.Substrate is a cotton.With heating core, by copper wire, constantan wire, manganese-copper filament, nickel filament or other the conductor wire material of outsourcing insulant made down by heating core for substrate.These wire rods all have certain resistance value, as alternating current or DC current by the time produce electrocaloric effect, reach the purpose of heating.The heating core two ends are connected with supply socket.This socket can be connected with the outer low pressure power supply, and external low-tension supply comprises that voltage is not more than 36 volts alternating current power supply or dc source.Heating core has heat-insulation layer outward, and heat-insulation layer is sewn into the multilamellar cotton.Heat-insulation layer has the sterilizing covers of the bag shape of cotton system outward.Frenulum is arranged on the sterilizing covers, and frenulum is used for making this device location.When this device uses, connect external power source, tube for transfusion is clipped in the thermal treatment zone of heating core formation, and tube for transfusion just is heated, and the liquid that flows through tube for transfusion is just heated, and the degree of heating can be by the voltage-regulation of external power source.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Substrate (1) is a cotton, long 150～250 millimeters, wide 15～40 millimeters.Below the substrate (1) heating core (2).Heating core (2) is that the enamel covered wire of 0.19～0.25 millimeter of 8～17 ohm, diameter is made by the two ends resistance value, can be made into any geometric figure and is distributed under the substrate (1).The two ends of heating core (2) are connected with supply socket (3).Be heat-insulation layer (4) below the heating core (2), heat-insulation layer (4) is made by the multilamellar cotton and is formed.Sterilizing covers (5) is the satchel that cotton is sewn into, and it is enclosed within the outside of heat-insulation layer (4).Frenulum (6) is made by banded cotton, is used for the location.When present embodiment used, it was that 150～250 millimeters part is clipped in by in the reduced venous transfusion warmer of the centrage among the figure that tube for transfusion has length, when external power source with after supply socket (3) is connected, tube for transfusion is heated, the liquid that flows through tube for transfusion is just heated.External power source is to be not more than 36 volts alternating current power supply or dc source, and the degree that liquid is heated can be regulated by the voltage of external power source.
