Abstract

The utility model relates to a low-pressure electronic transfusion heater which can heat a transfusion tube when a patient is in transfusion under the conditions of low temperature or in winter. The heater is composed of a miniature power supply device, a special socket and a heater. When the utility model is used, the power supply device converts 220V voltage into 36V safety voltage through a transformer, and the 36V safety voltage enters the heater through the special socket. Electric energy is changed into heat energy by a resistance wire. Finally, physic liquor is heated by the transfusion tube circled on the heater. The utility model is widely suitable for heating when liquid is transfused at hospital wards or medical clinics.

Description

The Low-voltage Electronic infusion warmer

This utility model relates to a kind of medical apparatus and instruments, specifically can be during patient infusion under the situation that a kind of winter or temperature are lower to the Low-voltage Electronic infusion warmer of tube for transfusion heating, and it is widely used in hospital ward or the medical clinic transfusion is used.

At present, when known patient infusion need be heated, usually use that hot water bag or high temp glass are bottled goes into hot water and heat to tube for transfusion, need families of patients to provide for oneself, when attending to the patient, increase a lot of troubles again, there is a kind of infusion warmer to use in addition in minority medical institutions, it is to be contained in the sealed plastic bag after being mixed by several chemical drugss, add less during use and rub with regard to producing heat and can medicinal liquid be heated up to the tube for transfusion heating, the longest service time, less than was three hours, and temperature can reduce gradually, will use two if each transfusion time surpasses three hours, and expense is up to quaternary, because this infusion warmer is disposable, not only increase the weight of patient economy burden, and can cause environmental pollution, so its use has been subjected to great limitation.In view of the foregoing, numerous medical personnel and patient press for a kind of all sense operations, easy to use, infusion warmer tool flexibly.

The purpose of this utility model be exactly to provide in order to overcome weak point of the prior art a kind of with electric energy as thermal source, and the temperature height can be regulated and control stable work in work, the infusion warmer of Low-voltage Electronic flexibly easy for operation.

The purpose of this utility model can be finished in the following manner: this Low-voltage Electronic infusion warmer is made up of miniature charger, private jack, heater three parts.Described miniature charger is that the side at the micro plastic housing is equipped with a voltmeter, a display lamp, a single-pole switch, two sockets, and a fuse is arranged in the housing, transformator and resistance, and the opposite side of housing leads to the 220V attaching plug.Connected mode is: plug cord connects voltmeter, single-pole switch, fuse, transformator, resistance, display lamp, socket.Described private jack is to be made of two display lamps, two single-pole switch, two resistance and two sockets.Described heater is to be distributed with a plurality of holes equably in the middle part of the interior circle of an earthenware and cylindrical, is preferably 12 holes, and the inside, 12 holes is wound with resistance wire, and resistance wire connection lead-out wire, lead-out wire connect a special-purpose latch.The outside of earthenware bag one deck insulant, the insulant top is overlapped a metal tube again, also can be aluminum, copper, but be preferably stainless.Respectively there is an insulation, heat insulation and have the end socket of tube for transfusion draw-in groove at the metal tube two ends, and two end sockets are fixed by a long filament.The heater latch is inserted private jack, and charger has dedicated line to be connected with private jack, and the socket on miniature charger and the private jack is the circle hole shape socket.Its operation principle is that charger becomes the 36V safe voltage with the 220V power supply through transformator, enters heater through private jack again, changes electric energy into heat energy by resistance wire, after the tube for transfusion on heater heats up medicinal liquid.

This utility model has been compared following remarkable advantage with prior art: first, this Low-voltage Electronic infusion warmer is the 36V safe voltage, so in use can not produce any harm to human body, not only can not produce new polluter, and the use of can be for a long time heating during for hospital ward or medical clinic transfusion, both can also can many people use simultaneously for single use.The second, hospital installs and uses this warmer and had both made things convenient for patient, can increase income again, and can too much not increase the weight of patient's financial burden, and each needs several expenses of sharing money.The 3rd, its fitting operation is easy to use, flexible, in use only need the increase and decrease tube for transfusion on heater around the number of turns what or increase and decrease amount of infusion, just temperature can be adjusted to steady temperature.The 4th, it extensively is suitable for hospital ward and medical clinic, is convenient to promote the use of.

Below in conjunction with circuit theory diagrams and embodiment structure of the present utility model and operating position are further described.

Fig. 1 is circuit theory diagrams of the present utility model.

Sequence number and title among the figure

(1) miniature charger, (2) private jack, (3) heater.

With reference to Fig. 1, this Low-voltage Electronic infusion warmer is by miniature charger (1), private jack (2), heater (3) three portion of tissue.Attaching plug on miniature charger (1) and 220V power connection, the voltmeter on miniature charger (1) housing just shows its voltage value, opens single-pole switch, and transformator is started working, and fuse shields to transformator in the housing.The bright explanation transformator of display lamp on the housing is in work.Miniature charger (1) has a dedicated line to be connected with private jack plug (2), and the special-purpose latch on the heater (3) is connected with private jack (2), and electric current enters heater (3) by private jack (2), and the resistance wire in the heater (3) just produces heat.To be wrapped on heater (3) metal tube 3～4 circles to the disposable transfusion device flexible pipe of patient infusion, the two ends of flexible pipe are stuck in the draw-in groove at heater (3) two ends, cause the infusion tube can not play, have guaranteed the safety of patient infusion.Heater (3) can be directly installed on ward or outpatient service, and a miniature charger (1) can ensure two wards, heats when two patient infusions can be given simultaneously with a private jack (2) in each ward.
