[0001] The present invention relates to the technical field of medical equipment, in particular to a tumor chemotherapy bed. Background Art
[0002] During cancer chemotherapy, patients need to stay in bed for a long time, and existing cancer chemotherapy beds have many shortcomings. On the one hand, the posture adjustment function of traditional chemotherapy beds is relatively simple, and usually only simple angle adjustments can be made. It is difficult to make precise posture adjustments according to the patient's specific body shape and treatment needs, causing patients to maintain uncomfortable postures for a long time, which can easily lead to problems such as pressure sores. On the other hand, existing chemotherapy beds lack effective heating devices and cannot provide patients with a suitable temperature environment, especially in cold environments, which may make patients feel uncomfortable and affect the treatment effect. In addition, traditional chemotherapy beds do not have physiological monitoring functions. Medical staff cannot obtain patients' physiological indicators in real time, and it is difficult to detect and deal with abnormal conditions of patients in a timely manner. Summary of the Invention

[0028] In this embodiment, as a preferred technical solution, the airbag array 3 is composed of multiple airbags arranged in a matrix form, each airbag is independent of each other, and each airbag is connected to the air pump 8 through an independent air pipe. The air pump 8 is arranged at the bottom of the bed 1 and is electrically connected to the controller.
[0029] In this embodiment, as a preferred technical solution, the temperature feedback module includes a temperature sensor 9, which is arranged on the flexible electric heating film 4 and is used to collect temperature data of the flexible electric heating film. The temperature sensor 9 is electrically connected to the controller 7 and is used to transmit the temperature data to the controller.
[0030] In this embodiment, as a preferred technical solution, the bioimpedance sensor 6 and the optical blood oxygen probe 6 are provided in plurality and are evenly embedded and fixed inside the memory foam 2 with the monitoring end facing upwards in contact with the patient.
[0031] In this embodiment, as a preferred technical solution, a vomit collection assembly is provided on one side of the bed 1. The vomit collection assembly includes a collection trough 10, a diversion tube 11, a collection box 12, and a cleaning device. The collection trough 10 is fixed to the front edge of the bed 1. One end of the diversion tube 11 is connected to the bottom of the collection trough 10 and the other end is connected to the top of the collection box 12. The cleaning device includes a nozzle 13 and a water pump 14. The nozzle 13 is located inside the collection trough 10. The water pump 14 is connected to the nozzle 13 via a pipe, and the other end of the water pump is connected to an external water source.
[0032] The working principle of the present invention is as follows: This tumor chemotherapy bed coordinates the various components, such as the position adjustment mechanism, the heating layer, and the physiological monitoring module, through a controller 7 to work together to provide patients with a comfortable and safe chemotherapy environment. The position adjustment mechanism utilizes the adaptive fit of the memory foam 2 and the independent inflation adjustment function of the airbag array 3 to achieve precise adjustment of the patient's position; the heating layer generates heat through the flexible electric heating film 4 and uses the temperature feedback module to monitor the temperature in real time, thereby achieving automatic adjustment of the bed temperature; the bioimpedance sensor 5 and the optical blood oxygen probe 6 of the physiological monitoring module collect the patient's physiological indicators in real time, providing medical staff with a basis for monitoring the condition. At the same time, when abnormalities are detected, the position adjustment mechanism is linked to prevent pressure sores and other problems. In addition, the vomit collection component can promptly collect and clean up the patient's vomit, keeping the area around the bed clean.
[0033] The working process of the present invention is as follows:
[0034] 1. Patient lying down: The patient lies on the bed 1 covered with memory foam 2. The memory foam 2 adaptively fits the patient's body shape to provide initial comfortable support for the patient.
[0035] 2. Body Position Adjustment: Medical personnel operate controller 7 to send commands to air pump 8, which inflates or deflates the individual airbags in different areas of airbag array 3 through independent air tubes. For example, when a patient's waist needs support, controller 7 controls air pump 8 to inflate the airbags in the corresponding area of the waist, causing them to inflate and provide support. This allows for precise adjustment of the patient's body position, helping the patient find a comfortable position and avoiding pressure sores caused by prolonged posture.
[0036] 3. Temperature Regulation: The flexible heating film 4 is placed inside the memory foam 2, near the upper surface, and begins to generate heat evenly, providing a warm bed environment for the patient. A temperature sensor 9 is mounted on the flexible heating film 4, collecting real-time temperature data from the film and transmitting it to the controller 7. The controller 7 compares the received temperature data with a set temperature range. If the temperature falls below the lower limit of the range, the controller 7 increases the heating power of the flexible heating film 4; if the temperature rises above the upper limit, the controller 7 reduces the heating power of the flexible heating film 4, thereby maintaining a suitable bed surface temperature.
[0037] 4. Physiological Monitoring: A bioimpedance sensor 5 and an optical oximeter probe 6, evenly embedded and fixed within the memory foam 2 with the monitoring end facing upward, maintain real-time contact with the patient, collecting bioimpedance signals and blood oxygen saturation data, respectively. This collected data is transmitted to a controller 7. If the bioimpedance sensor 5 detects excessive local pressure on the patient, or if the optical oximeter probe 6 detects abnormal blood oxygen saturation, signals that could lead to pressure sores, the controller 7 automatically adjusts the inflation state of the airbag array 3 and changes the patient's position to further prevent the occurrence of pressure sores. Medical staff can also access these physiological indicators through the controller 7 to keep abreast of changes in the patient's condition.
[0038] 5. Vomitus Management: When a patient vomits, the vomitus falls into a collection trough 10 fixed to the front edge of the bed 1. It is then directed through a diversion tube 11 to a collection box 12 for collection. When it is necessary to clean the collection trough 10, medical personnel activate a water pump 14, which delivers water from an external source through a pipe to a nozzle 13. The nozzle 13 then sprays water into the collection trough 10, flushing and cleaning it and keeping the area around the bed clean and hygienic.
[0039] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
