Technical Field

[0001] The present invention relates to the field of medical nursing equipment, and in particular to a tumor chemotherapy nursing method and equipment. Background Art

[0002] Neurotoxicity caused by chemotherapy drugs is one of the common clinical problems in cancer treatment, especially for patients who need long-term treatment. Neurotoxicity caused by chemotherapy drugs may manifest as discomfort symptoms such as pain, paresthesia and movement disorders, which reduce the quality of life of patients to varying degrees.

[0003] At present, the following methods are usually used in clinical treatment of neurotoxicity caused by chemotherapy drugs: reducing drug dosage, suspending treatment, using neurotrophic drugs and rehabilitation therapy. These methods are less effective in preventing and improving neurotoxicity and may reduce the effectiveness of chemotherapy itself. Summary of the invention

During the infusion of chemotherapy drugs, pressure is applied to or the temperature is lowered on the patient's limbs to increase the centripetal blood flow of the limbs and reduce the accumulation of chemotherapy drugs in the nerves of the limbs, thereby reducing the risk of peripheral nerve toxicity in the limbs.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a structural block diagram of the present invention. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example: See Figure 1 As shown, on the one hand, the present invention provides a tumor chemotherapy care method. During the infusion of chemotherapy drugs, the patient's limbs are pressurized or cooled to increase the centripetal blood flow of the limbs, reduce the accumulation of chemotherapy drugs in the limb nerves, and thus reduce the risk of peripheral nerve toxicity in the limbs.

[0021] On the other hand, the present invention provides a tumor chemotherapy nursing device, which includes a monitoring system, an actuator liquid air bag, an air pressure control system and a liquid temperature control system.

[0022] The actuator liquid air bag is a flexible and deformable bag structure filled with gas or liquid or a combination thereof, and the actuator liquid air bag is used to wrap around the patient's limb to control pressurization and cooling;

[0023] The air pressure control system includes a pressurizing system, which is connected to the actuator liquid air bag and is used to provide a constant and controllable gas pressure to the actuator liquid air bag;

[0024] The liquid temperature control system includes a liquid storage tank, a refrigeration unit and a heating unit. The liquid storage tank is connected to the actuator liquid gas bag and is used to provide temperature-controllable liquid to the actuator liquid gas bag. The refrigeration unit and the heating unit are both arranged in the liquid storage tank and are used to cool or heat the liquid storage tank.

[0025] The monitoring system includes a monitoring unit and a control unit. The monitoring unit includes a peripheral circulation monitor, which is used to monitor the peripheral blood supply status of the patient's limbs; the control unit controls the gas pressure provided by the pressurization system and the liquid temperature provided by the liquid storage tank according to the monitoring parameters of the monitoring unit.

[0026] The monitoring unit may also include other biological parameter monitoring devices, such as heart rate monitors, blood pressure monitors, etc., to monitor the patient's physiological response. These devices will continuously measure the biological parameters and transmit the data to the control unit. The control unit uses the data from the biological parameter monitoring devices to adjust the liquid temperature and balloon pressure according to the patient's physiological condition, thereby ensuring individualized and safe treatment.

[0027] The execution liquid air bag is a bag structure with at least two mutually isolated cavities, and the plurality of cavities can directly contact the patient's limbs through the surface of the execution liquid air bag, at least one of which is used to fill gas, and at least one of which is used to fill liquid. The volume of the execution liquid air bag can be adjusted by controlling the gas pressure of the cavity filled with gas to adjust the tightness of the patient's limb. The temperature of the cavity filled with liquid can be adjusted by controlling the temperature of the execution liquid air bag covering the limb.

[0028] Furthermore, the execution liquid airbag is a double-layered bag structure formed by an outer airbag and an inner liquid bag. The inner liquid bag controls the temperature of the outer airbag, and the outer airbag controls the air pressure when the execution liquid airbag is wrapped.

[0029] On the basis of the above embodiment, the pressurization system includes a pressure source, which can be an air pump and connected to the execution liquid air bag through a gas delivery pipeline, for delivering positive pressure gas to the execution liquid air bag, an air inlet valve is provided on the gas delivery pipeline, an air pressure sensor is installed in the execution liquid air bag, an air outlet valve is provided on the execution liquid air bag, and the air pressure sensor, the air inlet valve and the air outlet valve are all electrically connected to the control unit. The air pressure sensor is used to detect the air pressure in the execution liquid air bag, and the control unit controls the opening and closing degree or opening and closing of the air inlet valve and the air outlet valve to control the air pressure in the execution liquid air bag. In order to reduce the risk of peripheral nerve toxicity in the patient's limbs, the execution liquid air bag maintains a stable positive pressure and covers the patient's limbs, forcing the limb blood to flow toward the heart, thereby reducing the accumulation of chemotherapy drugs in the limb nerves.

[0030] On the basis of the above-mentioned embodiment, the liquid storage tank is connected to the execution liquid air bag through the water inlet pipe and the water outlet pipe to form a water circulation loop, and the water inlet pipe and the water outlet pipe are provided with a circulation pump; a temperature sensor is installed in the liquid storage tank, and the temperature sensor, the refrigeration unit and the heating unit are electrically connected to the control unit. The temperature sensor is used to detect the water temperature in the liquid storage tank, and the control unit controls the refrigeration unit and the heating unit to adjust the water temperature in the liquid storage tank. In order to reduce the risk of peripheral neurotoxicity in the patient's limbs, the water temperature in the liquid storage tank is maintained at a relatively low temperature and is coated by the execution liquid air bag and acts on the patient's limbs, forcing the limb blood temperature and flow rate to decrease, thereby reducing the accumulation of chemotherapy drugs in the limb nerves. The refrigeration unit can use compression refrigeration technology for refrigeration, and the heating unit can use an electric heater. Since both are mature technologies, they will not be repeated here.

[0031] On the basis of the above embodiment, the control unit includes a main control chip and a timer. At regular intervals, the timer outputs a signal to the main control chip. After receiving the signal, the main control chip starts the contraction and relaxation of the executive liquid air bag to prevent the limb blood vessels from being compressed for a long time and causing tissue necrosis. The contraction and relaxation regulation can be achieved by controlling the opening and closing degree of the inlet valve and the outlet valve to control the volume contraction of the executive liquid air bag.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
