Abstract

The utility model relates to a cooling device for medical treatment, comprising a vapor compression refrigeration system, a casing, a helmet, a cold room, and a temperature controller. The refrigeration system, the helmet, and the cold room are respectively arranged in the casing; the temperature controller is arranged on a panel on the upper part of the front surface of the casing. As the evaporator of the refrigeration system is contacted with the helmet, accordingly, the temperature in the helmet can be reduced through the working of the refrigeration system. In addition, the temperature of the helmet can be kept within the temperature range which is regarded necessary for the medical staff forever under the action of the temperature controller. The patient who has a high fever can be continuously, stably, and effectively cooled through the utility model.

Description

Temp. reducing device

This utility model relates to a kind of medical heat sink.

Carry out safe and effective Physical temperature-lowering is the thing that medical personnel dream of for a long time to the hyperpyrexia patient." science magazine " the 7th phase of nineteen eighty-three report, the someone trial-produces successfully a kind of by the Electronic ice cap that semiconductor refrigeration system constitutes is installed on common medicated cap.It is said, this Electronic ice cap except that be mainly used in make summer people's brains keep clear-headed, in hospital, also can replace ice bag is hyperpyrexia patient cooling.But this Electronic ice cap per hour just can reduce by 0.1 ℃ with hyperpyrexia patient's body temperature, and efficient is too low, is difficult to reach the purpose of rescue patient.

Task of the present utility model is to make a kind of new medical treatment device, for the hyperpyrexia patient continues, stable effectively cooling, thereby alleviates the patient suffering, and the disease controlling development impels disease to take a turn for the better.

Its solution is: compressor, vaporizer, device for drying and filtering, the capillary tube of a vapour compression refrigeration system all are loaded in the housing, and condenser is loaded on this back side of shell.

The helmet and cold house also are housed in the housing, temperature controller, display lamp, on and off switch and cold house's wicket are housed on the housing front upper panel, fix a winter protection shoulder pad on the panel that is positioned at helmet bottom, this winter protection shoulder pad is made with artificial leather parcel sponge.

The helmet comprises helmet shell, band and the headrest three parts.Helmet shell is to be made of inside and outside two cylinders that weld together, and seals between two cylinders, and interior dress solidification temperature is greater than 0 ℃ liquid (as ethanol etc.), and the vaporizer of refrigeration system promptly coils on inner cylinder; Band is to make with screw thread cloth parcel one deck sponge on the Elastic Steel guide frame, is loaded on the helmet shell opening part; The headrest places the helmet shell bottom in the band, makes with artificial leather parcel sponge.

The cold house is a cuboid, places on the helmet shell, and eight little cold bags made from rubber place in the cold house in two batches by turns and patient oxter, femoral artery place, and little cold bag can pick and place by cold house's wicket on the housing.

All make with galvanized iron sheet or aluminium sheet housing, helmet shell, cold house, but also plastic compression forms.Post heat-insulation layer on the inner walls, between helmet shell and the housing, between cold house and the housing and the back side of cold house's wicket.

Temperature controller links to each other with the power line of refrigeration system, and its temperature-sensitive bag contacts with helmet shell, and temperature-control range is between-15～37 ℃.For medical personnel can be regulated at any time according to conditions of patients, temperature controller can divide several retainings in its temperature-control range.

Because this utility model is equipped with vapour compression refrigeration system and temperature controller, continue, stablize and effectively cooling so can be the hyperpyrexia patient, thereby the disease controlling development promotes the disease improvement.The special construction of the helmet had both played heat-blocking action, had guaranteed the comfortable of patient's head and the convenience of using again.Other eight little cold bags also can place cold house and patient's oxter, femoral artery place in two batches by turns, further increase cooling-down effect.

Further improvement of the utility model is: the band of the helmet in the scope of internal diameter 100～200mm, can prepare a plurality of so that medical personnel arbitrarily select for use according to different patients' capitiform.

Accompanying drawing has been described an embodiment of the present utility model.

Figure one is overall structure figure of the present utility model, wherein: 1. housing, 2. cold house's wicket, the 3. helmet, 4. temperature controller, 5. display lamp, 6. on and off switch, 7. compressor.

Figure two is profiles of the present utility model, wherein: 8. helmet shell, 9. cold house, 10. heat-insulation layer, (11) headrest, (12) winter protection shoulder pad, (13) condenser, (14) vaporizer, (15) band.

When turning on the power switch 6., refrigeration system of the present utility model is promptly started working.Because the vaporizer (14) of refrigeration system coils on helmet shell inner cylinder 8., so in the refrigeration system work process, the helmet temperature 3. temperature with the vaporizer (14) of refrigeration system all the time is identical.Again because temperature controller temperature-sensitive bag 4. is 8. to contact with helmet shell, so be brought down below temperature controller 4. during the lower limit temperature of temperature-control range when helmet temperature 3., temperature controller is i.e. disconnection 4., thereby cuts off the electricity supply, and 7. compressor is quit work; When helmet temperature 3. rises to temperature controller 4. during the ceiling temperature of temperature-control range, 4. temperature controller is energized, and 7. compressor is reworked.So go round and begin again, can guarantee that patient's head places helmet temperature 3. in it to be in medical personnel forever and thinks in the necessary temperature range.(this temperature range has several retainings between-15～37 ℃, 4. medical personnel can select arbitrarily by temperature controller according to conditions of patients.）

Meanwhile, four the little cold bags of cold house in 9. can from housing 1. the cold house's wicket on the front upper panel take out 2., place patient oxter, femoral artery place, thereby play the effect that increases cooling area, increase cooling-down effect.In addition, when taking out four little cold bags 9. from the cold house, four little cold bags that can simultaneously will be standby be put into the cold house, like this, can guarantee when the little cold bag cooling-down effect that places patient oxter, femoral artery place weakens replacement at any time.

Be positioned at the helmet 3. the winter protection shoulder pad (12) on the lower case panel can prevent that patient's shoulder from catching cold.Place in the band (15) helmet shell 8. the headrest (15) of bottom then guaranteed patient's the comfortable of position of resting the head on.

By the above-mentioned a series of activities of this utility model, finally be reached for the purpose that the hyperpyrexia patient continues, stablizes and effectively lowers the temperature.
