Abstract

The utility model discloses a transfusion liquid heater, which is composed of a bag-shaped heating body, a controller and a leading wire whose one end is connected with a power supply plug, and the other end of the leading wire is connected to the bag-shaped heating body via the controller. The bag-shaped heating body is made of flexible insulation materials, the side of the bag-shaped heating body is provided with an observation hole, electric heating wires are arranged in the middle of the bag wall of the bag-shaped heating body, and the heating temperature of the electric heating wires making not more than the temperature of the human body as standard. The outer sides of the electric heating wires are additionally provided with heat-proof and heat-insulation cloth to prevent temperature loss. The utility model has the advantages of reasonable structure, scientific design, low cost, convenient operation and safety.

Description

Transfusion liquid heater

This utility model belongs to ohmage heater technical field, relates to a kind of heater of expanded surface area in a two dimensional surface basically, particularly a kind of transfusion liquid heater (H05B3/20).

When patient needs intravenous drip, usually directly use room temperature state medicinal liquid down, and instil when entering in the patient body when temperature is lower than 36 ℃ medicinal liquid, will inevitably make the decline of patients'blood temperature, to the cold sensation of people, in the time of seriously even cause monospasm.Running into above-mentioned situation, generally is to impose hot compress to patient, with the temperature at raising instillation position, but does not often have than obvious effects.

The purpose of this utility model is to provide a kind of transfusion liquid heater, with it transfusion liquid is heated to temperature near human body, to avoid the problems referred to above.

Task of the present utility model realizes in the following manner, form transfusion liquid heater by bag shape calandria, controller and lead-in wire, one end of lead-in wire connects attaching plug, other end via controller is connected to a bag shape calandria, its key is that a bag shape calandria is made with flexible insulating material, and the side of bag shape calandria offers observation port, so that observe the residue injection, preventing that medicinal liquid from using up makes air mistake enter human body, is arranged with electric heating material in the middle of the bag wall of bag shape calandria.

Above-mentioned electric heating material can adopt heating wire or Electric radiant Heating Film, and its heating temp is as the criterion to be no more than human body temperature.Heating wire preferably adopts withstand voltage 300 volts, the high tenacity heating wire that normal temperature resistance is 810 ohm.

For ease of the processing and fabricating of bag shape calandria, above-mentioned flexible insulating material is preferably waterproof insulation cloth or flexible asbestos cloth, also can directly use cotton.

For preventing the loss of temperature, in the middle of the bag wall of bag shape calandria, can set up the heat-resisting insulation cloth of one deck, this heat-resisting insulation cloth should be in the outside of heating wire or Electric radiant Heating Film.

Below in conjunction with accompanying drawing shown in the embodiment this utility model is described in further detail.

Fig. 1 is the structure cut-away view of transfusion liquid heater;

Fig. 2 is the structure cut-away view of bag shape calandria in the transfusion liquid heater;

Fig. 3 is the electrical schematic diagram of transfusion liquid heater middle controller;

Fig. 4 is the user mode reference diagram of transfusion liquid heater.

With reference to Fig. 1, bag shape calandria 1 via controller 2 and the 3 connection attaching plugs 4 that go between, the side of bag shape calandria 1 offers observation port 5, so that observe the residue injection, preventing that medicinal liquid from using up makes air mistake enter human body, the bag of bag shape calandria 1 is arranged with high tenacity heating wire 6 in the middle of keeping away, and high tenacity heating wire 6 is kept away middle with the bag that U type mode is arranged in bag shape calandria 1.

In conjunction with Fig. 2, the bag wall of bag shape calandria 1 adopts multiple structure, is respectively waterproof insulation cloth 7, freestone cotton 8, high tenacity heating wire 9, heat-resisting fabric 10 and empire cloth or cotton 11 from inside to outside.

With reference to Fig. 3, controller 2 carries out power control by resistance 12 series connection blood pressure lowerings to high tenacity heating wire 9, switch 13 in the controller 2 is used for controlling the duty of this transfusion liquid heater, and light emitting diode 14 then is used for showing the duty of this transfusion liquid heater.

Fig. 4 is the user mode reference diagram of transfusion liquid heater, as can be seen from Figure 4, the container 15 that transfusion liquid is housed is placed in the bag shape calandria 1 of transfusion liquid heater, by the observation port 5 that bag shape calandria 1 side is offered, the surplus that can observe injection easily.

In order to realize the purpose to the transfusion liquid heating, above-mentioned bag shape calandria also can be made simple shape, perhaps makes more simple rectangle blanket shape.In the occasion of making rectangle blanket shape, should add velcro at two minor face place, so that it is coated on the container of transfusion liquid easily.

Because above-mentioned electric heating material adopts heating wire or Electric radiant Heating Film, and its heating temp can not surpass human body temperature, do not taking place under the prerequisite that quality changes so can guarantee medicinal liquid, has that to alleviate patient painful and be beneficial to the effect that drug effect is brought into play.

Because the bag at bag shape calandria has additional heat-resisting insulation cloth in the middle of the wall, and this heat-resisting insulation cloth is in the outside of heating wire or Electric radiant Heating Film, so can effectively prevent the loss of temperature.

This transfusion liquid heater is rational in infrastructure, design science, with low cost, esy to use, safe and reliable.
