Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tissue decalcifiers, in particular to a temperature regulation system for an ultrasonic cylinder of a tissue decalcifier. Background Technique
[0002] When pathologists diagnose bone diseases and diseases related to bone changes, they often need to take bone specimens from the lesion site for pathological section examination. Bone specimens for pathological examination must be decalcified before being sectioned and observed under a microscope. The decalcification process needs to be completed by a tissue decalcifier. Some tissue decalcifiers use an ultrasonic generator and an ultrasonic controller to achieve decalcification treatment with the help of ultrasonic waves. In this process, in order to protect the sample, the temperature in the ultrasonic cylinder needs to be controlled. However, most ultrasonic cylinders only have a heating system and no cooling system. There are also some tissue decalcifiers that use a cooling fan to cool the cylinder body as a whole. In this process, the heat exchange with the external environment through the overall heat radiation of the cylinder shell is relatively slow, resulting in a slow temperature regulation speed of the device and low temperature regulation ability. It cannot well ensure that the reaction temperature of the tissue sample quickly returns to the set temperature range and needs to be improved. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0017] Please refer to Figure 1 , this embodiment provides a technical solution: a temperature regulation system for an ultrasonic cylinder of an tissue decalcifier, including an ultrasonic cylinder housing 1;
[0018] Ultrasonic cylinder housing 1: Radiating fins 3 are evenly distributed on both its left and right sides. Symmetrically distributed mounting brackets 4 are provided at the upper end of the ultrasonic cylinder housing 1. Uniformly distributed cooling fans 5 are provided on the front wall of the mounting brackets 4. The cooling fans 5 are installed in cooperation with the radiating fins 3. The material of the radiating fins 3 is copper or aluminum. A condensing pipe 6 is provided between the front and rear sides and the bottom surface of the ultrasonic cylinder housing 1. Flange plates are provided at both the liquid inlet and outlet of the condensing pipe 6. It also includes a single-chip microcomputer 2. The single-chip microcomputer 2 is located outside the ultrasonic cylinder housing 1. The input end of the single-chip microcomputer 2 is electrically connected to an external power supply. The output end of the single-chip microcomputer 2 is respectively electrically connected to the input ends of the cooling fans 5. A circulation pump 7 is connected in series at the liquid inlet of the condensing pipe 6. The input end of the circulation pump 7 is electrically connected to the output end of the single-chip microcomputer 2. The rear side of the circulation pump 7 is fixedly connected to the front side of the ultrasonic cylinder housing 1. A temperature sensor 9 is installed on the right wall of the ultrasonic cylinder housing 1. The temperature sensor 9 is bidirectionally electrically connected to the single-chip microcomputer 2. Uniformly distributed mounting holes 10 are provided on the upper side of the ultrasonic cylinder housing 1. A thermal conductive silicone grease coating is provided on the outside of the ultrasonic cylinder housing 1. The device is fixed to the corresponding position in the tissue decalcifier through the mounting holes 10 with bolts. Subsequently, both the liquid inlet and outlet of the condensing pipe 6 are connected to the supply pipe and outlet pipe of the external cooling liquid through flange plates. When the temperature is adjusted during the use of the ultrasonic cylinder of the tissue decalcifier, the single-chip microcomputer 2 activates the temperature sensor 9. The temperature sensor 9 detects the temperature inside the ultrasonic cylinder for the tissue decalcifier through the internal detection element and transmits the detection result to the single-chip microcomputer 2 in the form of an electrical signal. When the single-chip microcomputer 2 obtains that the temperature data is greater than the set value, the single-chip microcomputer 2 activates the circulation pump 7 to make the external cooling liquid enter the condensing pipe 6. The condensing pipe 6 is wrapped around the outside of the ultrasonic cylinder housing 1. The cooling liquid transfers heat through the wall of the ultrasonic cylinder housing 1 through the condensing pipe 6, thereby taking away the heat inside the ultrasonic cylinder for the tissue decalcifier and cooling it. At the same time, part of the heat inside the ultrasonic cylinder for the tissue decalcifier is released to the outside in the form of heat transfer through the radiating fins 3. And at this time, the single-chip microcomputer 2 activates the cooling fans 5. The cooling fans 5 operate to increase the gas flow speed on the surface of the radiating fins 3, accelerate the heat exchange speed, and further improve the heat dissipation efficiency of the radiating fins 3 for the ultrasonic cylinder of the tissue decalcifier, accelerate the temperature adjustment speed of the ultrasonic cylinder of the tissue decalcifier, and protect the samples inside the ultrasonic cylinder of the tissue decalcifier. The thermal conductive silicone grease coating improves the thermal conductivity of the ultrasonic cylinder housing 1, thereby increasing its heat conduction and heat dissipation speed and accelerating the cooling. This device combines air-cooled heat dissipation and water-cooled heat dissipation, can quickly cool and adjust the temperature inside the ultrasonic cylinder for the tissue decalcifier, and then improve the adjustment speed of the temperature of the tissue sample returning to the set value range during the decalcification process, and avoid the interference of temperature fluctuations on the decalcification of the tissue sample;
[0019] Among them, heating sheets 8 are evenly distributed on the front and rear walls of the ultrasonic cylinder housing 1. The input ends of the heating sheets 8 are electrically connected to the output end of the single-chip microcomputer 2. The heating sheets 8 can be ceramic heating sheets. When the temperature data is less than the set value, the single-chip microcomputer 2 activates the heating sheets 8, so as to quickly heat the ultrasonic cylinder for tissue decalcification instrument, ensuring that the reaction temperature in the ultrasonic cylinder for tissue decalcification instrument always remains within the set range.
[0020] The working principle of the temperature regulation system of the ultrasonic cylinder for tissue decalcification instrument provided by the present utility model is as follows: The device is fixed to the corresponding position in the tissue decalcification instrument through the mounting holes 10 with bolts. Subsequently, both the liquid inlet and outlet of the condenser tube 6 are connected to the liquid supply pipe and the liquid discharge pipe of the external cooling liquid through flange plates. When the temperature is regulated during the use of the ultrasonic cylinder of the tissue decalcification instrument, the single-chip microcomputer 2 activates the temperature sensor 9. The temperature sensor 9 detects the temperature inside the ultrasonic cylinder for tissue decalcification instrument through the internal detection element, and transmits the detection result to the single-chip microcomputer 2 in the form of an electrical signal. When the single-chip microcomputer 2 obtains that the temperature data is greater than the set value, the single-chip microcomputer 2 activates the circulation pump 7 to make the external cooling liquid enter the condenser tube 6. The condenser tube 6 is wrapped around the outside of the ultrasonic cylinder housing 1. The cooling liquid transfers heat through the wall of the ultrasonic cylinder housing 1 through the condenser tube 6, thereby taking away the heat inside the ultrasonic cylinder for tissue decalcification instrument and cooling it. At the same time, part of the heat inside the ultrasonic cylinder for tissue decalcification instrument is released to the outside in the form of heat transfer through the heat dissipation fins 3. And at this time, the single-chip microcomputer 2 activates the heat dissipation fan 5. The operation of the heat dissipation fan 5 increases the gas flow velocity on the surface of the heat dissipation fins 3, speeds up the heat exchange speed, and further improves the heat dissipation efficiency of the heat dissipation fins 3 for the ultrasonic cylinder for tissue decalcification instrument, speeds up the temperature regulation speed of the ultrasonic cylinder for tissue decalcification instrument, and protects the sample inside the ultrasonic cylinder for tissue decalcification instrument. The heat conductivity of the ultrasonic cylinder housing 1 is improved through the thermal conductive silicone grease coating, and further the heat conduction and heat dissipation speed is improved. When the temperature data is less than the set value, the single-chip microcomputer 2 activates the heating sheets 8, so as to quickly heat the ultrasonic cylinder for tissue decalcification instrument, ensuring that the reaction temperature in the ultrasonic cylinder for tissue decalcification instrument always remains within the set range.
[0021] It should be noted that, in the above embodiments, the single-chip microcomputer 2 disclosed can be STM32, the heat dissipation fan 5 can be AS05006L5, the circulation pump 7 can be mzr-11557, the heating sheets 8 can be MCH ceramic heating elements, the temperature sensor 9 can be AM2303, and the single-chip microcomputer 2 controls the heat dissipation fan 5, the circulation pump 7, the heating sheets 8 and the temperature sensor 9 to work using the commonly used methods in the prior art.
