Abstract

The utility model relates to a medical temperature lowering instrument with a semiconductor for refrigeration. The utility model comprises a refrigerating cap, a temperature lowering plate, a circulating water pipe, a heat radiating fin, a control circuit, a base, a head support, etc., wherein, refrigerating units composed of refrigerating sheets and heat exchangers for the refrigerating sheets are arranged in the refrigerating cap and the refrigerating plate. The cold ends of the refrigerating sheets cling to the refrigerating caps and the inner wall of the refrigerating plate. The hot ends of the refrigerating sheets cling to the heat exchangers for the refrigerating sheets. Each heat exchanger for the refrigerating sheets penetrates the heat radiating fin through the circulating water pipe and is connected with a water tank for forming a water circulating system for cooling and heat radiation. The refrigerating cap arranged on the guideway of the base can slide along a track. The refrigerating plate is connected with the water circulating system through a flexible water pipe. The utility model in which the refrigerating cap and the refrigerating plate can flexibly move for temperature lowering physiotherapy for a patient can be widely applied to the field of medical care.

Description

Lowering-tempreture instrument with semiconductor medical freezer

This utility model relates to a kind of instrument that is used for the body temperature lowering physical therapy, and particularly the conductor refrigeration Medical Refrigerating Instruments belongs to medical instruments field.

At present, hospital is for cerebral trauma, cerebral edema, and cerebral hemorrhage in the treatment of diseases processes such as high fever, need use ice cube (bag), cold water to carry out cold compress and reduce patient temperature usually to the patient body processing of lowering the temperature.Its cooling-down effect is poor, and temperature is wayward, needs constantly to change ice, water, brings wound and intracranial infection also for easily postoperative patient, gives in the whole therapeutic process and brings great inconvenience.

The purpose of this utility model is to provide a kind of Medical Refrigerating Instruments, and it is fast to have cooling rate, and the control temperature is accurate, simple to operation, does not pollute characteristics such as wound.

Of the present utility model being contemplated that, by the refrigeration medicated cap, the cooling plate, semiconductor cooler, the cooling heat dissipation water circulation system, temperature-control circuit is formed this cooling instrument, utilize the conductor refrigeration principle with refrigerating sheet and refrigerating sheet heat exchanger as a frigorific unit, several frigorific units are placed on the refrigeration medicated cap, in the cold plate, the refrigerating sheet cold junction is close to the refrigeration medicated cap, the inwall of cold plate, hot junction are close to the refrigerating sheet heat exchanger, cooling water becomes the loop through refrigeration water of radiation blood circulation, take away its heat, make and constantly finish heat exchange between refrigeration medicated cap and the patient, thereby reach the effect that reduces body temperature.

Fig. 1 is this utility model schematic diagram.

Fig. 2 is this utility model refrigeration cap schematic diagram.

Below in conjunction with Fig. 1,2 further narrate this utility model, by refrigeration medicated cap 1, cooling plate 16, refrigerating sheet 2, refrigerating sheet heat exchanger 3, circulating water pipe 4, fin 5, fan 6, water pump 7, water tank 8, control circuit 9, temperature sensor 10, base 11, guide rail 12, head bracket 13, head rest 14 grades constitute the conductor refrigeration Medical Refrigerating Instruments, 3 is a frigorific unit in refrigerating sheet 2 and the refrigerating sheet heat exchange, refrigerating sheet 2, refrigerating sheet heat exchanger 3 is placed in the housing of refrigeration medicated cap 1 and cold plate 16, its circuit connection control circuit 9, refrigerating sheet 2 cold junctions are close to refrigeration medicated cap 1, on cooling plate 16 inwalls, the hot junction is close on the refrigerating sheet heat exchanger 3, and refrigerating sheet heat exchanger 3 passes fin 5 and water tank 8 by circulating water pipe 4, water pump 7 connects and composes the cooling heat dissipation water circulation system, its heat is blown away in the upper end that fan 6 is placed in fin 5, and the inwall of refrigeration medicated cap 1 and cold plate 16 is close in temperature sensor 10, its circuit connection control circuit 9, can establish a plurality of frigorific units in refrigeration medicated cap 1 and cold plate 16 shells, each unit is controlled respectively by control circuit 9 by circulating water pipe 4 string (also) connection, and refrigeration medicated cap (1) is placed on the guide rail 12 of base 11, can be along slide, make things convenient for the patient to adjust the cooling position, head bracket 13 is fixed on the base 11, and the other end is taken through pulley 15 and is placed on refrigeration medicated cap 1 inner shell, can slide front and back, head rest 14 is placed head for fabric is fixed on the head bracket 13 for the patient.

This utility model is in implementation process, refrigeration medicated cap, cold plate inwall are selected the good metal of heat conductivity for use, material such as foam plastics that housing filling thermal insulation is good, frigorific unit is distributed in four sides about reaching up and down of refrigeration medicated cap respectively, cold plate is connected with the cooling heat dissipation water circulation system by flexible water conduit, can move flexibly, the oxter that is placed on the patient maybe needs the position that lowers the temperature.

Characteristics of the present utility model are that cooling effect is obvious, cooling rate is fast, temperature is adjustable, do not pollute patient's wound, easy and simple to handle, owing to used refrigeration medicated cap removable frame and flexible cold plate just to make patient's head pass in and out refrigeration medicated cap adjustment cooling position at an easy rate, also available cold plate is to the processing of lowering the temperature of other position of patient.
