Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary devices, specifically relating to a constant temperature heating device platform. Background Technology

[0002] Intraoperative hypothermia refers to a patient's core body temperature falling below 36°C at any point during surgery, excluding therapeutic and planned hypothermia. It is a common perioperative complication. Perioperative hypothermia can lead to various serious complications such as coagulation disorders, postoperative chills, infection, and postoperative reactive mental disorders, increasing hospital stay and mortality. Guidelines emphasize that medical staff should strengthen the monitoring and prevention of intraoperative hypothermia. The standard operating room temperature is typically set between 21°C and 25°C. In clinical practice, to ensure the comfort of surgical personnel, the temperature is often set lower, significantly lower than the normal core body temperature. Furthermore, the laminar flow environment increases air convection, facilitating heat dissipation from objects in the environment. Surgical instruments are mostly made of metal, which has a high thermal conductivity, meaning they can rapidly transfer heat and cold. Exposure to the low temperature and laminar flow environment of the operating room will cause the surface temperature of surgical instruments to decrease with increasing exposure time. When medical staff use these instruments to manipulate internal tissues, it accelerates the loss of body heat, increasing the likelihood of intraoperative hypothermia.

[0003] Therefore, there is an urgent need for a new type of surgical instrument table to meet the requirements of constant temperature heating or insulation of surgical instruments. Utility Model Content

[0030] The output of the temperature control unit 28 is connected to the input of the safety protection circuit 27, and also to the temperature sensor 25. The temperature control unit 28 is used to control the heating power of the heating layer 23 according to the temperature detected by the temperature sensor 25, so that the heating layer 23 is kept at a constant temperature.

[0031] The output terminal of the power supply module 29 is connected to the input terminal of the temperature control unit 28. The power supply module 29 is used to rectify the external AC power into DC power and transmit it to the temperature control unit 28.

[0032] In this embodiment, the safety protection circuit 27, the temperature control unit 28, and the power module 29 are disposed on the same circuit board 1 and arranged between the heat insulation layer 21 and the instrument table body 10.

[0034] The number of lifting table legs 31 is four, which are vertically distributed at the four corners of the bottom of the main body of the instrument table 10. The bottom of the lifting table legs 31 is equipped with lockable casters 31a.

[0035] There are 4 connecting rods 32, which are arranged horizontally to fix adjacent lifting table legs 31, thereby reducing the degree of horizontal swaying of the constant temperature heating instrument table 100.

[0050] The role and effect of the embodiments

[0051] According to this embodiment, a constant temperature heating instrument table includes: an instrument table body; a heating assembly, which includes: a first insulating layer, a heating layer, and a second insulating layer, which are sequentially disposed on the instrument table body from bottom to top to heat surgical instruments placed thereon; a temperature sensor disposed on the second insulating layer for detecting the temperature generated by the heating layer; a temperature control unit connected to the temperature sensor and the heating layer, which controls the heating power of the heating layer based on the temperature detected by the temperature sensor to maintain constant temperature heating of the heating layer; and an integrated controller connected to the temperature control unit, which controls the start-up of the heating layer and sets the detection temperature of the temperature sensor. The integrated controller is also connected to an external power supply to power the various power-consuming components in the constant temperature heating instrument table.

[0052] Therefore, the constant temperature heating instrument table in this embodiment can heat or keep the surgical instruments at a constant temperature, accurately sense the temperature changes at different positions on the table, and thus control the temperature within a preset range.

[0053] Furthermore, the heating assembly also includes a heat insulation layer disposed at the bottom of the first insulating layer. This arrangement reduces the downward heat loss generated by the heating layer, allowing the heat generated by the heating layer to be transferred upwards as much as possible to heat the surgical instruments.

[0054] Furthermore, the heating assembly also includes a surface layer that covers the second insulating layer and the temperature sensor, on which surgical instruments are placed for heating. This arrangement protects the second insulating layer and the temperature sensor, preventing the surgical instruments from scratching them.

[0055] Furthermore, the heating assembly also includes a power module, which is connected in series in the line connecting the temperature control unit and the integrated controller. This power module rectifies the AC power transmitted from the integrated controller into DC power before transmitting it to the temperature control unit. The heating assembly also includes a safety protection circuit, which is connected in series in the line connecting the temperature control unit and the heating layer. This configuration further protects the heating layer from damage caused by current overload.

[0056] Furthermore, the constant-temperature heating instrument table also includes a lifting assembly, which comprises: lifting table legs, at least three in number, evenly distributed vertically at the bottom of the instrument table body; a lead screw drive component, located at the bottom of the instrument table body and connected to the lifting table legs, for driving the lifting table legs to move; a lifting motor, connected to the lead screw drive component, for driving the lead screw drive component to move; and a lifting controller, connected to the integrated controller and the lifting motor, for controlling the number of current pulses input to the lifting motor according to the instructions input from the integrated controller. This configuration allows the constant-temperature heating instrument table to be manually raised and lowered, facilitating the surgical personnel's access to surgical instruments.

[0057] Furthermore, the integrated controller features a display screen that shows in real-time the temperature detected by the temperature sensor, the preset temperature, and the height of the adjustable table legs. This configuration allows surgical personnel to easily monitor parameters such as temperature and instrument table height.

[0058] Furthermore, the lifting assembly also includes several connecting rods arranged horizontally to securely connect adjacent lifting table legs. This design reduces the degree of horizontal swaying of the thermostat when the thermostat is moved.

[0059] Furthermore, the bottom of the adjustable table legs is equipped with lockable casters. This design allows the temperature-controlled instrument table to be easily moved and repositioned.

[0060] Furthermore, the constant-temperature heating instrument table also includes a battery, which is electrically connected to the temperature control unit, the lifting controller, and the integrated controller to provide power. The battery is connected to an external power source through the integrated controller, allowing it to be charged by an external power source. This configuration enables the constant-temperature heating instrument table to provide heating and insulation functions for surgical instruments even when there is a power outage.
