Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of skin temperature monitoring and adjusting, and particularly relates to an intraoperative body temperature nursing intelligent temperature control system and a control method thereof. BACKGROUND

[0002] In modern surgical procedures, patients often need to maintain a supine and stationary state for a long time and are operated in an open wound environment, which can easily lead to abnormal body temperature fluctuations, especially in a low-temperature operating room environment, the risk of hypothermia in patients is greater. Intraoperative hypothermia not only causes postoperative shivering, decreased immunity, coagulation dysfunction and other complications, but also may affect the metabolic rate of anesthetic drugs and prolong postoperative recovery time. Therefore, accurate management and regulation of the body temperature of patients during surgery has become an important issue in clinical anesthesia and surgical nursing.

[0003] Traditional intraoperative body temperature regulation methods mainly rely on physical heating devices such as heating blankets, electric heating blankets, and hot water circulating pads to achieve the effect of heat preservation through overall or local heating. However, such devices generally have problems such as uneven temperature regulation, temperature control lag, slow temperature response, and cannot achieve zoned management of different body parts, which can easily cause some parts to overheat or other parts to remain in a low-temperature state, lack of personalized control means, and are difficult to meet the actual needs of high-precision surgical body temperature management.

[0004] In addition, existing devices often ignore the sweating phenomenon caused by tension, pain or environmental changes in patients during surgery, and sweat is easy to accumulate on the skin surface of patients, which not only affects comfort, but also can increase the risk of skin eczema or bedsores. Traditional devices usually do not have ventilation or dehumidification functions and cannot perform real-time drying treatment on the skin contact surface, which affects the quality of intraoperative nursing and has a large room for improvement.

[0005] Based on the above problems, there is an urgent need for an intraoperative body temperature nursing system and a control method thereof that has a reasonable structure, a high degree of intelligence, can achieve zoned temperature control, active dehumidification, and has heat preservation and ventilation functions to meet the body temperature control needs in different surgical scenarios, improve patient comfort and safety during surgery, and provide more efficient nursing means for medical staff.

[0009] Further, the placing groove is provided with a suction channel at the bottom, the lower end of the suction channel is connected with a suction pipe, and a gas flow valve four is arranged on the suction pipe.

[0010] Further, a temperature sensor is arranged on the breathable pad above each chamber, and the temperature sensor is used to detect the body surface temperature of the corresponding part of the human body.

[0011] Further, a heat preservation covering mechanism is arranged on the side surface of the mattress body; the heat preservation covering mechanism comprises a heat preservation cloth which can be pulled out; the heat preservation cloth can move forward and backward; a connecting rod is arranged at the outer end of the heat preservation cloth; the heat preservation covering mechanism further comprises a connecting barrel which is connected with the mattress body, a rotating rod which is rotatably arranged in the connecting barrel, a roller which is movably arranged on the rotating rod and can rotate, and the heat preservation cloth is wound on the roller; a heat preservation cloth limiting mechanism is arranged on the connecting barrel.

[0012] Further, the heat preservation cloth limiting mechanism comprises a connecting plate, a limiting roller which can move left and right is arranged in the connecting plate, a limiting plate and a moving plate which can move left and right are arranged in the connecting plate, a plurality of springs are uniformly distributed between the limiting plate and the moving plate, and the inner end of the moving plate and the limiting roller are rotationally connected; a threaded rod is rotatably arranged at the middle part of the outer end surface of the limiting plate, and the threaded rod is rotationally connected with the connecting plate; a limiting strip and a rotating rod are arranged on the connecting barrel, and the rotating rod is rotationally connected with the connecting barrel; the outer side surface of the limiting strip is an inner concave arc surface, and the center axis of the inner concave arc surface of the limiting strip is at the same height as the center axis of the limiting roller; a connecting ring is rotatably arranged on the side surface of the roller, a handle is arranged on the connecting ring, a cover plate is detachably arranged on the outer side surface of the connecting barrel, a moving groove is formed on the cover plate, the handle penetrates through the moving groove, the handle can move along the moving groove, the connecting plate moves along the moving groove, and the rear end of the connecting plate is connected with the handle. A reset mechanism is arranged on the connecting barrel, and the reset mechanism drives the rotating rod to rotate and reset.

[0013] The application is used to place the mattress on the bed, and the patient lies on the mattress. During the operation, the temperature sensor detects the body surface temperature of different parts of the patient. When the local body surface temperature of the patient is detected to be too high, the gas flow valve two and the gas flow valve three on the air inlet pipe and the air outlet pipe are opened, cold gas is supplied to the chamber through the air inlet, the gas in the chamber is discharged through the air outlet, and then the temperature of the gas in the chamber is reduced. When the temperature in the chamber is reduced to a set value (the change of the gas temperature in the chamber is detected by the detection module), the gas flow valve two and the gas flow valve three on the air inlet pipe and the air outlet pipe are closed (or the replacement rate of the gas flow in the chamber is adjusted by adjusting the opening degree of the gas flow valve two and the gas flow valve three). The gas temperature is transmitted to the air-permeable pad through the upper part of the mattress body, and the temperature is transmitted through the air-permeable pad to reduce the local body temperature. Similarly, when it is needed to provide temperature to the human body, hot gas is supplied to the chamber.

[0014] When it is needed to blow and cool or warm the human body, the gas flow valve two and the gas flow valve one are opened, and the gas flow valve three is closed. The gas enters the air-permeable pad through the chamber, and the air-permeable pad cools or warms the human skin. The above-mentioned method can quickly adjust the temperature of the human skin, and the blowing can realize the air-permeable effect of the human skin, and remove the sweat odor generated by the human skin.

[0015] In addition, the air exhaust pipe and the grid groove are provided. Through the above-mentioned structure, the air-permeable pad, the air-permeable port and other structures, the air-permeable pad can be quickly dried, and the sweat generated by the human body can be removed. That is, the gas flow valve four is opened, the air is exhausted outward through the air exhaust pipe, the gas flow valve two on the air flow valve one and the local or whole chamber is opened (and the gas is supplied to the chamber), and the gas in the chamber is blown to the human body through the air-permeable pad. The air is exhausted through the air exhaust pipe, that is, the gas is removed through the grid groove, and then the local rapid cooling or warming of the human body is realized, and the sweat (keeping the body dry) and odor generated by the human skin are removed.

[0016] According to the need, the temperature of the gas in the chamber can be adjusted individually or integrally. The gas temperature required by the air inlet pipe is supplied to the chamber, and the gas supply device for supplying gas to the air inlet pipe is not limited in technology, which is the prior art and can realize the function required by the application.

[0017] According to the need, all the air inlet pipes and the air outlet pipes can be respectively connected to the air inlet main pipe and the air outlet main pipe, or can be connected to each gas supply device.

[0018] When the patient needs to be locally warmed, the local part of the human body can be covered and warmed by the warming cover mechanism. That is, the warming cloth limiting mechanism and the roller are moved forward and backward along the moving groove by holding the handle, so that the warming cloth is moved to the part of the human body that needs to be locally covered and warmed. The handle is pulled outward, at which time the warming cloth drives the roller to rotate, and in turn drives the rotating rod to rotate. When the rotating rod rotates, the reset mechanism is pressed (the reset mechanism can be a torsional spring provided on the rotating rod, and the two ends of the torsional spring are connected to the rotating rod and the connecting cylinder, respectively. That is, when the rotating rod rotates, the torsional spring is stressed, and when the rotating rod is not stressed, the torsional spring resets and drives the rotating rod to rotate and reset). At this time, the limiting roller moves outward under the extrusion of the warming cloth, the spring is stressed, the limiting roller and the limiting strip are disconnected from the extrusion of the warming cloth, and the limiting roller rotates when the warming cloth is pulled outward, which can avoid the friction between the warming cloth and the limiting roller, thereby preventing damage to the warming cloth. When the warming cloth is pulled to the required length, the warming cloth is pulled to the other side of the mattress body, at which time the limiting roller is not stressed by the warming cloth, the spring drives the moving plate to move, so that the limiting roller and the limiting strip cooperate to extrude and limit the warming cloth. The concave arc surface on the side of the limiting strip can increase the contact area with the warming cloth, increase the friction force, and avoid the movement of the warming cloth. The warming cloth is then covered on the human body to achieve local covering and warming of the human body. The distance between the limiting plate and the limiting strip can be adjusted by rotating the threaded rod, thereby changing the extrusion force of the limiting roller cooperating with the limiting strip on the warming cloth, and simultaneously changing the extrusion force of the limiting cloth on the limiting roller when it is pulled outward.

[0019] When the warming cloth needs to be stored, the limiting cloth is straightened, the limiting roller is extruded by the warming cloth, the limiting roller is moved away from the limiting strip, the warming cloth is not limited by the friction of the limiting roller cooperating with the limiting strip, and the warming cloth is stored on the roller under the driving of the reset mechanism (that is, when the reset mechanism resets, the rotating rod is driven to rotate and reset, and in turn the roller is driven to rotate and reset, thereby achieving storage of the warming cloth). The above temperature sensor, detection module, control of the valve, gas temperature supplied by the gas supply mechanism, and air extraction start-stop of the air extraction mechanism are all controlled by the controller. The connection relationship between them is all prior art, and will not be described in detail. The controller and the above-mentioned electrical devices are all prior art, and can achieve the functions required by the present application.

[0020] An intraoperative body temperature care intelligent temperature control method includes the following use steps:

[0021] S1: Preoperative preparation and system initialization

[0022] S1.1 Place the mattress body flat on the operating bed surface to ensure that it fully conforms to the patient's body;

[0023] S1.2 Check whether the air inlet pipe, air outlet pipe, air extraction pipe, and air source system, air extraction mechanism are firmly connected to ensure that each pipeline is unobstructed;

[0024] S1.3 Power on and start the controller system, set the target temperature range for each compartment, and activate all detection modules and sensors;

[0025] S1.4 Check the surface cleanliness of the breathable pad and confirm that it is placed in the placement slot and properly aligned with the air vent.

[0026] S2, Automatic intraoperative temperature control

[0027] The S2.1 controller receives data in real time from the temperature sensing modules of each compartment and the temperature sensor of the breathable pad.

[0028] S2.2 If the temperature of a certain compartment exceeds the set value or the body surface temperature of a person needs to be changed, the controller controls the gas flow valves two and three to open, the air inlet pipe delivers high-temperature / low-temperature gas to the compartment, and the exhaust pipe discharges the original gas, thereby realizing gas replacement and temperature regulation.

[0029] After the gas temperature inside the S2.3 chamber is regulated, the gas is transferred to the breathable pad and then to the patient's body surface through the vent, forming a localized and precise temperature control.

[0030] S2.4 When the temperature returns to the set range, the controller controls the gas flow valve to automatically close or maintain a constant flow rate for fine-tuning and heat preservation.

[0031] S3. Intraoperative ventilation and dehumidification procedures

[0032] S3.1 When the patient's local skin surface humidity is high or there is sweat accumulation, the system can activate the ventilation and dehumidification function;

[0033] S3.2 Open gas flow valve one and gas flow valve two on the relevant compartment, and at the same time close gas flow valve three at the exhaust port;

[0034] S3.3 The relatively dry gas enters the corresponding chamber through the air inlet and is then introduced into the breathable pad through the air vent, delivering airflow to the human body surface;

[0035] S3.4 Simultaneously open the gas flow valve four and start the air extraction mechanism. The residual gas and human sweat odor at the bottom of the placement tank are quickly extracted through the air extraction pipe and the mesh groove to achieve dryness and breathability.

[0036] S4, Localized Insulation Covering Operation

[0037] S4.1 Manually hold the lever and push it along the moving groove on the cover plate to release the limiting mechanism from the limiting state;

[0038] S4.2 Continue to pull the insulation cloth out above the target area, and unfold the insulation cloth by moving the connecting rod to achieve coverage and insulation;

[0039] S4.3 After the handle is released, the limiting roller and the limiting strip are reset, and the heat preservation cloth is limited and fixed;

[0040] S4.4 After the heat preservation cloth is covered, the gas temperature control is matched, the constant temperature of the covered area can be maintained, and the intraoperative heat preservation effect is enhanced;

[0041] S4.5 When the heat preservation cloth needs to be withdrawn after the operation, the heat preservation cloth is straightened again and is separated from the limiting structure, the rotating rod and the roller are driven to rotate by means of the reset mechanism, and the automatic rolling and storage of the heat preservation cloth are realized.

[0042] At the same time, the following use method can be adopted to enhance the local wind blowing temperature adjustment mode:

[0043] 1. Without changing the overall temperature control state, in order to enhance the cooling or heating efficiency of a certain part, the operator can individually select to open the gas flow valve two of the specific chamber, and at the same time, the flow valve one is opened;

[0044] 2. The temperature adjustment gas is directly sent into the corresponding chamber, and is quickly blown to the patient's skin surface through the air permeable pad;

[0045] 3. If it is necessary to simultaneously discharge moisture or odor, the gas flow valve four and the air extraction mechanism are opened, the air extraction pipe is used to quickly extract and discharge the gas from the grid groove, and the heat dissipation and drying effect is improved;

[0046] 4. This mode is suitable for local sweating within a short time during the operation, and the intraoperative body temperature regulation response is not sensitive, and is helpful to improve the temperature control response speed and comfort.

[0047] Beneficial effects:

[0048] The technical scheme of the present application has the following remarkable beneficial effects:

[0049] 1. Realize accurate intelligent temperature control during operation, and protect the stability of the body temperature of the patient

[0050] By arranging a plurality of parallel chambers in the mattress body, and using the temperature sensing module to monitor the gas temperature in each chamber in real time, and combining the body surface temperature sensor arranged on the air permeable pad, the body temperature change of different parts of the patient during the operation can be accurately perceived. The system intelligently judges whether the temperature exceeds the set range through the controller, and automatically adjusts the temperature and flow of the incoming and outgoing gas, so as to realize dynamic regulation of the gas temperature in the chamber, so that the temperature transmitted to the human body by the air permeable pad is always maintained in the ideal range, effectively preventing adverse reactions such as intraoperative hypothermia or overheating, and improving the intraoperative safety and comfort.

[0051] 2. With a multifunctional gas circulation system, the heat exchange and dehumidification capacity are improved

[0052] The application designs a ventilation structure between the chamber and the ventilation mattress, and combines the air inlet and outlet arranged at the bottom of the chamber and the air extraction pipe and the grid groove arranged at the bottom of the bed mattress to construct a complete circulating air system. By adjusting the air flow valve, the air blowing, temperature rising and temperature lowering operations of the local or overall area can be realized, and the air extraction structure can quickly take away the local sweat and odor, so that the dryness and comfort of the patient's body during the operation are effectively maintained. The system increases the body surface dehumidification and ventilation functions on the basis of the gas temperature regulation, and has strong practicality and comprehensive regulation performance.

[0053] 3. Provide an innovative thermal covering mechanism to realize local rapid thermal insulation and convenient storage

[0054] The application also introduces a novel thermal covering mechanism, which realizes the local covering and thermal insulation function of the specific part of the patient through the movable thermal blanket and the matching limiting and resetting mechanism. The thermal blanket can be freely stretched or stored according to the needs, and the limiting structure effectively prevents the sliding of the thermal blanket through the cooperation of the limiting roller and the limiting strip, thereby improving the stability and durability of the thermal blanket during use. The setting of the resetting mechanism also enables the thermal blanket to be automatically and quickly recovered after use, thereby improving the convenience and neatness of the system. The thermal mechanism has strong adaptability and can flexibly cooperate with the temperature control system to improve the overall temperature control efficiency.

[0055] In summary, the intraoperative body temperature nursing intelligent temperature control system of the application not only has reasonable structure and complete function, but also integrates intelligent temperature control, gas circulation regulation, sweat and odor removal and local intelligent thermal insulation, thereby significantly improving the intraoperative nursing quality and patient comfort experience, and having good clinical application prospect and promotion value.

[0070] The temperature sensor 3 is arranged on the air-permeable pad 2 above each chamber, and can detect the body surface temperature of the human body part above each chamber.

[0071] The side of the mattress body 1 is provided with a heat preservation covering mechanism; the heat preservation covering mechanism can preserve the heat of the covered part of the human body, and the temperature of the gas transmitted by the air-permeable pad 2 can well keep the temperature of the covered part constant, the heat preservation covering mechanism comprises a heat preservation cloth 29 which can be pulled out and stored quickly when not in use; the heat preservation cloth 29 can move forward and backward to cover different positions of the human body; the outer end of the heat preservation cloth 29 is provided with a connecting rod 23; the heat preservation covering mechanism further comprises a connecting barrel 16 connected with the mattress body 1, a rotating rod 30 is rotatably arranged in the connecting barrel 16, a roller is movably and rotatably arranged on the rotating rod 30, and the heat preservation cloth 29 is wound on the roller; a heat preservation cloth 29 limiting mechanism is arranged on the connecting barrel 16, and the heat preservation cloth 29 limiting mechanism can limit the heat preservation cloth 29 to avoid movement.

[0072] The heat preservation cloth 29 limiting mechanism comprises a connecting plate 19, a limiting roller 25 is movably arranged in the connecting plate 19, a limiting plate 28 and a moving plate 26 are movably arranged in the connecting plate 19, a plurality of springs 27 are uniformly distributed between the limiting plate 28 and the moving plate 26, and the inner end of the moving plate 26 is rotationally connected with the limiting roller 25; a threaded rod 18 is rotatably arranged on the middle part of the outer end surface of the limiting plate 28, and the threaded rod 18 is rotationally connected with the connecting plate 19; a limiting strip 24 and a rotating rod 30 are arranged on the connecting barrel 16, and the rotating rod 30 is rotationally connected with the connecting barrel 16; the outer side surface of the limiting strip 24 is an inner concave arc surface, and the center axis of the inner concave arc surface of the limiting strip 24 is at the same height as the center axis of the limiting roller 25; a connecting ring 31 is rotatably arranged on the side of the roller, a handle 22 is arranged on the connecting ring 31, a cover plate 21 is detachably arranged on the outer side surface of the connecting barrel 16, a moving groove 20 is formed in the cover plate 21, the handle 22 penetrates the moving groove 20, the handle 22 can move along the moving groove 20, the connecting plate 19 moves along the moving groove 20, and the rear end of the connecting plate 19 is connected with the handle 22; a reset mechanism 17 is arranged on the connecting barrel 16, and the reset mechanism 17 drives the rotating rod 30 to rotate and reset.

[0073] In use, the mattress is placed on a bed, a patient lies on the mattress, and the temperature sensor 3 detects the body surface temperature of different parts of the patient during the operation. When the local body surface temperature of the patient is detected to be too high, the gas flow valve two 13 and the gas flow valve three 12 on the gas inlet pipe and the gas outlet pipe are opened, cold gas is supplied to the chamber through the gas inlet 7, and the gas in the chamber is discharged through the gas outlet 8, thereby reducing the temperature of the gas in the chamber. When the temperature in the chamber is reduced to a set value (the change of the gas temperature in the chamber is detected by the detection module 32), the gas flow valve two 13 and the gas flow valve three 12 on the gas inlet pipe and the gas outlet pipe are closed (or the replacement rate of the gas flow in the chamber is adjusted by adjusting the opening degree of the gas flow valve two 13 and the gas flow valve three 12). The gas temperature is transferred to the air-permeable pad 2 through the upper part of the mattress body 1, and the temperature is transferred through the air-permeable pad 2 to reduce the local body temperature. Similarly, when it is needed to provide temperature to the human body, hot gas can be supplied to the chamber.

[0074] When it is needed to blow and cool or warm the human body, the gas flow valve two 13 and the gas flow valve one 6 are opened, and the gas flow valve three 12 is closed. The gas enters the air-permeable pad 2 through the chamber, and the air-permeable pad 2 cools or warms the human skin. The above-mentioned method can quickly adjust the temperature of the human skin, and the blowing can achieve the air-permeable effect of the human skin, and remove the sweat odor generated by the human skin.

[0075] In addition, the air exhaust pipe 10 and the grid groove 4 are provided. Through the cooperation of the above-mentioned structure, the air-permeable pad 2, the air-permeable port 5 and the like, the air-permeable pad 2 can be quickly dried, and the like. That is, the gas flow valve four 11 is opened, air is exhausted outward through the air exhaust pipe 10, the gas flow valve two 13 on the gas flow valve one 6 and the local or whole chamber is opened (and gas is supplied to the chamber), and the gas in the chamber is blown to the human body through the air-permeable pad 2. The air is exhausted through the air exhaust pipe 10, that is, the gas is taken away through the grid groove 4, thereby achieving the local rapid cooling or warming of the human body while taking away the sweat generated by the human skin (keeping the body dry) and the odor.

[0076] According to the need, the temperature of the gas in the chamber can be adjusted individually or integrally. The gas temperature required for the gas supply to the chamber is supplied to the gas inlet pipe, and the gas supply device for supplying gas to the gas inlet pipe is not limited in technology, and is a prior art which can achieve the functions required by the present application.

[0077] According to the need, all the gas inlet pipes and the gas outlet pipes can be respectively communicated to the gas inlet main pipe 15 and the gas outlet main pipe 14, or can be connected to each gas supply device.

[0078] When the patient needs to be locally warmed, the local part of the human body can be covered and warmed by the warming covering mechanism. That is, the warming cloth 29 is moved to the part of the human body that needs to be locally covered and warmed by moving the warming cloth 29 limiting mechanism and the roller along the moving groove 20 forward and backward by holding the handle 22. The warming cloth 29 is pulled outward by holding the connecting rod 23, at which time the warming cloth 29 pulls the roller to rotate, thereby driving the rotating rod 30 to rotate. The rotating rod 30 drives the reset mechanism 17 to be pressed when rotating (the reset mechanism 17 can be a torsional spring provided on the rotating rod 30, the two ends of the torsional spring are connected with the rotating rod 30 and the connecting cylinder 16, etc., that is, when the rotating rod 30 rotates, the torsional spring is stressed, and when the rotating rod 30 is not stressed, the torsional spring resets to drive the rotating rod 30 to rotate and reset), at which time the limiting roller 25 is moved outward under the extrusion of the warming cloth 29, the spring 27 is stressed, the limiting roller 25 and the limiting strip 24 are disconnected from the extrusion of the warming cloth 29, and the limiting roller 25 rotates when the warming cloth 29 is pulled outward, which can avoid the friction between the warming cloth 29 and the limiting roller 25, thereby preventing the warming cloth 29 from being damaged. When the warming cloth 29 is pulled to the required length, the warming cloth 29 is pulled to the other side of the mattress body 1, at which time the limiting roller 25 is not stressed by the warming cloth 29, the moving plate 26 is moved by the spring 27, so that the limiting roller 25 and the limiting strip 24 extrude and limit the warming cloth 29. The side of the limiting strip 24 is concave arc-shaped, which can increase the contact area with the warming cloth 29, increase the friction, and avoid the movement of the warming cloth 29. The warming cloth 29 is covered on the human body to realize the local covering and warming of the human body. The distance position of the limiting plate 28 from the limiting strip 24 can be adjusted by rotating the threaded rod 18, thereby changing the extrusion degree of the limiting roller 25 cooperating with the limiting strip 24 on the warming cloth 29, and changing the extrusion degree of the limiting cloth on the limiting roller 25 when pulled outward.
