Abstract

The utility model relates to a medical instrument for warm keeping treatment after repairing wounds of acropodium of hands and feet, in particular to a constant-temperature constant-humidity acropodium warm keeping box, which consists of a warm keeping box and a CPU temperature and humidity self control system, wherein the warm keeping box is provided with an acropodium extending opening and a viewing window, and the CPU temperature and humidity self control system controls temperature and humidity inside the warm keeping box. The CPU temperature and humidity self control system is formed by connecting a CPU control chip with a temperature acquisition circuit, a humidity acquisition circuit, a digital display circuit, a keyboard setting circuit and a solid relay control circuit, and the solid relay control circuit is respectively connected with a heater and a humidifier which are arranged into the control warm keeping box. The constant-temperature constant-humidity acropodium warm keeping box overcomes shortages that temperature and humidity can not be controlled and strong light interferes sleep of patients during a heat lamp warm keeping treatment process, provides the best warm keeping recovery environment for recovery of acropodium wound surfaces, avoids thrombus caused by pachyhemia due to drying, provides a rest environment without interference for the patients, is more favorable for recovery of wound surfaces, and increases postoperation treatment effect of the acropodium.

Description

Constant temperature, constant humidity acra thermal protection box

Technical field:

This utility model relates to a kind of Medical Instruments, a kind of specifically constant temperature, constant humidity acra thermal protection box that uses when wound surface needed warming treatment that be applied in after the repair in trauma of brothers' acra position.

Background technology:

After the repair in trauma of brothers' acra position, some cases is as from disconnected replanting, needing wound surface is carried out warming treatment after the operation such as blood vessel injury, though the roasting lamp that uses during treatment can provide a partial hot environment to wound surface, but in use be prone to phenomenon too high or too low for temperature, can't realize constant control temperature; Also can't realize control simultaneously,, blood is concentrated easily make thrombosis because of dry environment causes limbs moisture content excessive vaporization to humidity; The high light that roasting lamp is sent also seriously disturbs patient's sleep, influences the recovery effects of patient's wound.

Summary of the invention:

This utility model provides a kind of constant temperature, constant humidity acra thermal protection box, be used for after the repair in trauma of brothers' acra position the insulation of wound surface postoperative being treated, it has overcome uses in the roasting lamp process and can not control moisture temperature reach the deficiency of baking the strong influence of light patient's rest of distributing of lamp.

This utility model comprise a thermal protection box that constitutes by closed box and the warming the temperature inside the box of control at 25 ℃～55 ℃, humidity in the CPU of 80%～90%RH humiture robot control system(RCS), described thermal protection box has acra to stretch into mouthful and observes wound surface and recover the transparent observation window that uses; Heater and the humidifier of regulating humiture are installed in the thermal protection box, CPU humiture robot control system(RCS) by a CPU control chip as central data processor, also have temperature collection circuit, humidity Acquisition Circuit, digital display circuit, the keyboard that are connected with the CPU control chip are provided with circuit and solid-state relay control circuit, wherein the solid-state relay control circuit connects heater and the humidifier in the control thermal protection box respectively, more than is the new basic design of this practicality.

For being easy to hands or sufficient acra stretches into thermal protection box, the acra of thermal protection box stretches into mouthful to be fit to do and overarches; Observe the recovery situation of wound surface postoperative for convenience, with the position of observation window be arranged on thermal protection box above, observation window can constitute the transparent sliding door that draws back with two.

In the thermal protection box Burdick lamp and illuminating lamp can be installed, Burdick lamp is used for using during sterilizing in the thermal protection box; Illuminating lamp uses when being used to observe the wound surface recovery situation.

In thermal protection box, utilize tank wall to do two interlayers, interlayer is by the interlayer wall and the thermal protection box tank wall is airtight constitutes, interlayer wall upper end leave with thermal protection box in the ventilation mouth of ventilating, different heating element heaters is installed in respectively in the interlayer, and the heating element heater in a side interlayer and the interlayer constitutes the heater in the thermal protection box; Water filling is used in another interlayer, constitutes humidifier in the thermal protection box with the undersurface heating element heater of interlayer after the water filling.

In order to make CPU humiture automatic control system have higher performance and to reach necessary requirement, the CPU control chip has adopted the LPC931 chip as central processing unit; Temperature collection circuit has adopted the DS18B20 digital temperature sensor, and the humidity Acquisition Circuit has adopted the DHT11 humidity sensor.

This utility model is 0～50 ℃ in temperature, humidity＜85%RH, do not have in the working environment of the no strong electromagnetic of corrosion, can control the interior temperature of couveuse 25 ℃～55 ℃ scopes, humidity is at the constant temperature of 80%～90%RH scope, constant humidity control, the warming recovery environment an of the best is provided for the recovery of acra wound surface, prevented that also high temperature drying from making blood concentrate the thrombosis that causes, also eliminated simultaneously the influence of high light to patient's sleep, for patient provides a glitch-free rest environment, help the recovery of wound surface more, improved the therapeutic effect of acra postoperative.
