Description

Medical cold and hot compress instrument

This utility model relates to a kind of medical apparatus and instruments, relates to a kind of apparatus that can carry out cold compress or hot compress to patient particularly.

Hospital often needs coma patient, hyperpyrexia patient and Patients Receiving Chemotherapy are carried out head and body part cooling, helps the coma patient recovery, forces the hyperpyrexia patient to bring down a fever, prevent wound infection, prevents chemotherapy patients's alopecia etc.Hospital also often needs hot compress is carried out in the patient body part, promotes local blood circulation, to reach the purpose of physical therapy and rehabilitation.

At present the widely used cold compress method of hospital is that ice cube is packed in the sack of hat that rubber makes and band shape, is worn on patient's head or local cooling is carried out at the position of required cold compress.Its poor refrigerating efficiency, service time is short, temperature is non-adjustable, is only applicable to the less demanding occasion of heat dissipation capacity.Some apparatuses in order to cold compress were arranged in recent years, as " head Semiconductor Physics cooling instrument " (notification number 2188363), " medical ice cap machine " (2123299), " automatic control cranium brain cooling hat " (2135349), " Medical freezing head hood " (2195314) etc., the employing semiconductor refrigerating that it has, the employing cold-producing medium that has refrigeration." head ice water circulation formula cooling machine " (2160369) then are will pump into the ice water circulation that ice cube is made with electromagnetic pump to give cold compress in the medicated cap.

Hot compress then is to use hot water bag, or is similar to various hot compress bands, the medicated cap of electric blanket, and the former heating effect is poor, service time short, and the latter uses heating wire, and is both dangerous, again can not temperature control.

The purpose of this utility model is at cold compress or the hot compress separately of above-mentioned apparatus, and problems such as cooling or heating effect is poor, service time is short, be intended to design good, safe in utilization comfortable, flexible to operation, the energy continuous operation, temperature automatically controlled of a kind of cooling or heating effect, can cold compress, again can hot compress, not only can separately use, but also the cold and hot deposited machine that can use simultaneously at head, body part.

The implementation of this utility model purpose is that Medical cold and hot compress instrument includes head-shield, hot and cold water generator 1, temperature demonstration and the controller of water cycle power set, band circulation water channel 24, deposited band, the bolster of band circulation water channel 35.Micropump 4, water container 5, electrothermal tube 13 are arranged in the hot and cold water generator.The refrigeration system that constitutes by compressor 8, filter and capillary tube 9, fan 10, condenser 11, evaporation coil 12.The outlet pipe 3 of water container passes through micropump 4 difference splice housings and/or applies the circulation water channel 24,35 of band, bolster, is back to return pipe 2 again.The temperature display controller is made of thermal resistance 14 that is attached to the water container outer wall and controller 15.

This utility model is described in detail in detail with reference to the accompanying drawings.

With reference to Fig. 1, have one to have insulating 6, uncap in top and the water container 5 that is incubated loam cake 7 is arranged in the hot and cold water generator.Evaporation coil 12 is installed in the water container, and cold-producing medium freezes to the recirculated water in the container in the in-tube evaporation heat absorption; A tubular heater 13 is installed in the bottom in the water container, and the recirculated water in the container is heated.Electromagnetic pump or other micropump 4 pump into head-shield 16 with the water in the container respectively by outlet pipe and/or apply with 17, in the circulation water channel 24,25 of bolster 18, are back in the water container by return pipe 2 after heat exchange.If cold compress requires zubzero temperature, then in water container, contain saline or other not congelative at low temperatures liquid.Thermostat 15 is measured temperature of liquid by the thermal resistance 14 that is attached to the water container outer wall, and adopts the break-make of two formula control mode control refrigeration compressors 8, electrothermal tube 13, temperature of liquid is controlled at the arbitrary steady temperature in-5 ℃～70 ℃.

Head-shield, deposited band and bolster are furnished with the aerating gasbag formula structure of circulation water channel, and are lined with sponge heat-insulating layer 26 and cotton cover 27,36 for the rubberized fabric flooring is pressed into.Hand aerating ballon 22 forms through inflating air bag 25,38,39 inflations in head-shield applies band and bolster of check valve 23, gas tube 21,33,34, can form the head-shield with certain rigidity, shape, deposited band and bolster.

When using this utility model, water inlet pipe 19,29,31 and outlet pipe 20,30,32 with head-shield, deposited band and bolster is communicated with the outlet pipe 3 and the return pipe 2 of hot and cold water generator respectively earlier, presses temperature required injection hot water, normal-temperature water, frozen water or saline in the water container.The temperature of thermostat is set in desirable value, refrigeration system or electrothermal tube are started working, and connect micropump 4, and then constant temperature frozen water in the water container or hot water pump into head-shield continuously and/or applies in band, the bolster, after the patient is carried out heat exchange by deposited position, return in the container.

This utility model to water in the water container or brinish refrigeration principle is, when the temperature of the water in the container is lower than the temperature controller design temperature, and refrigeration system work.Compressor 8 compresses the refrigerant vapour in the evaporation coil 12, make it to become high temperature and high pressure gas and enter condenser 11, at this, the heat that cold-producing medium will absorb from evaporation coil 12 forces through fan 10 passes to outside air, make condensation of refrigerant become liquid, flow through filter and capillary tube 9 expenditure and pressures and enter evaporation coil 12 evaporation, absorb the heat of water from container and make water for cooling; The cold-producing medium that is vaporized in the evaporation coil is inhaled into compressor again, and so constantly circulation is carried out cold compress to applying the position continuously.For making head-shield cover jail, also be provided with velcro 28 on it.

With reference to Fig. 2,3,4,5, circulation water channel 24 and aerating gasbag 25 parallel being spirally coiled on the head-shield 16 apply bandwidth 15cm, and long have three kinds of 25cm, 60cm and 120cm, can enclose respectively in position such as upper and lower extremities, thigh and breast waist and by velcro 37 to buckle.The wide 40cm of bolster, long 60cm can pillow head down, also can fill up in the back of the body down.

This utility model promptly can be used for hot compress, also can be used for cold compress, can use simultaneously head, body part, also can separately use.This utility model heat refrigeration reliable, safe in utilization comfortable, form is simply various, flexible to operation, can continuous operation, temperature automatically controlled, be the desirable cold and hot applicator tool of hospital ward, emergency room, physical therapy center, home care.
