[0025] This utility model embodiment provides a special sitting cushion for hemorrhoid surgery, such as... Figure 1-4 As shown below:

[0026] Seat cushion structure: including air pressure relief zone, memory foam layer 2, breathable surface layer 3, adjustable airbag 41, temperature-sensing physiotherapy module 5, etc.

[0027] Hollow Pressure Relief Zone 1: A hollow area is carefully designed in the center of the cushion. The precise location and size of this area are rationally planned to ensure that the anus and wound area are completely protected from direct pressure when the patient uses the cushion, greatly reducing the pressure on the wound while the patient is in a sitting position and providing a good external environment for wound healing.

[0028] Memory Foam Layer 2: High-density, high-quality memory foam is used as the main support material. This memory foam has excellent properties, automatically adjusting and evenly distributing the pressure applied to the buttocks according to the shape and pressure distribution of the human buttocks, providing all-round and comfortable support and effectively reducing buttock fatigue caused by prolonged sitting.

[0029] Breathable Surface Layer 3: The surface layer of the cushion is made of a material with both breathable and antibacterial properties. The breathability ensures local air circulation, avoiding stuffiness and dampness caused by prolonged contact; the antibacterial properties effectively inhibit the growth and reproduction of bacteria, preventing wound infection and providing a safe and hygienic environment for the patient's recovery.

[0030] Adjustable airbags 41: Adjustable airbags 41 are built into both sides of the seat cushion. Through special design and construction, these airbags 41 allow users to easily inflate or deflate them according to their actual needs, thereby flexibly adjusting the height and firmness of the seat cushion to meet the personalized comfort requirements of different patients at different stages of recovery. The airbags 41 are inflated through the air nozzles 42, which can be done manually or with an electric air pump. The deflation valve 44 is existing technology and can be selected according to actual needs, such as the Shanghai Youtai adjustable uniform speed deflation valve 44.

[0031] Thermotherapy Module 5: The seat cushion integrates a thermotherapy module 5, which mainly consists of a heating element 52. Through precise circuit design and a temperature control system, it can provide patients with gentle heat therapy. A suitable temperature can promote local blood circulation, accelerate metabolism, help wounds heal quickly, and relieve pain to some extent. This can be achieved by combining the heating element 52 (heating wire) and a controller 51, based on Joule's law (Q=I). 2 RT (where Q is heat, I is current, R is resistance, and T is time) – current flows through heating element 52 (heating wire), generating heat. A temperature sensor can also be included to monitor the surface temperature of the seat cushion. When the temperature reaches the set value, controller 51 adjusts the current to the heating wire, maintaining the seat cushion temperature within a comfortable range and preventing overheating. Both the temperature sensor and controller 51 are existing technologies, selected based on actual needs. For example, Dongguan Jinshun Sensor MF52 series is an NTC thermistor temperature sensor with high accuracy and sensitivity, capable of quickly and accurately sensing changes in the electric blanket's temperature. Different resistance and B values ​​can be selected according to different temperature measurement requirements, offering strong interchangeability. Controller 51 can be a Rainbow electric blanket intelligent timer dual-control temperature controller; main control chip: STC8H8K64U. Features: Includes a screen display, allowing for manual / automatic temperature adjustment control of ten levels, and allows for custom preheating time, custom constant temperature levels, and automatic screen-off and scheduled shutdown functions. Using a square wave to control the periodic switching of the load via optocoupler isolation by adjusting the duty cycle of the thyristor, temperature regulation is achieved. This is a typical application of low-voltage control over high-voltage systems.

[0032] Functional design:

[0033] Decompression function: The existence of the hollow decompression zone 1 fundamentally avoids direct pressure on the wound, significantly reduces the patient's pain sensation when sitting, and creates good conditions for wound healing without pressure interference.

[0034] Comfortable support: The memory foam layer 2, with its excellent pressure distribution properties, evenly bears the weight of the buttocks, keeping the buttocks in a comfortable state during long-term use and reducing discomfort and fatigue caused by uneven local pressure.

[0035] Breathable and infection-preventing: The breathable and antibacterial surface material effectively solves the problems of localized dampness and bacterial growth that are common in traditional seat cushions. Continuous air circulation keeps the area dry, while the antibacterial properties further reduce the risk of infection, providing a clean and healthy environment for wound healing.

[0036] Personalized Adjustment: The adjustable airbag 41 is designed with the individual physical differences and recovery needs of different patients in mind. Patients can adjust the height and firmness of the seat cushion at any time according to their own comfort level, achieving a personalized comfort experience.

[0037] Thermotherapy: The thermotherapy function provided by the thermotherapy module 5 can effectively promote local blood circulation, enhance the nutritional supply and metabolic capacity of tissues, and play a positive role in accelerating wound healing and relieving pain.

[0038] Material selection

[0039] Memory Foam Layer 2: High-density, high-resilience slow-rebound foam is selected, and its thickness is rigorously selected and set within the range of 5-10 cm. This thickness ensures sufficient support while fully utilizing the pressure-dispersing properties of memory foam, providing patients with a comfortable support experience.

[0040] Surface material: Use fabrics with excellent breathability and antibacterial effects, such as bamboo fiber fabric. Its natural breathability ensures smooth air circulation, while bamboo fiber itself has certain antibacterial properties; or use silver ion antibacterial fabric. Silver ions can effectively inhibit the growth and reproduction of various bacteria, providing antibacterial protection for wounds.

[0041] Airbag 41: Medical-grade silicone is used as the material for airbag 41. This material has good flexibility, sealing properties, and biocompatibility. After inflation, the height of airbag 41 is adjustable from 2 to 5 centimeters, which can meet the diverse adjustment needs of different patients for seat height and firmness.

[0042] Heating Module: The heating module uses heating wires or low-temperature heating elements, such as heating plates, which can operate stably within a safe temperature range. Through precise temperature control circuit design, the heating temperature range is set between 30-45℃. This temperature range effectively promotes local blood circulation without posing a risk of burns to the patient's skin. The heating module also features a timer function, allowing patients to set the therapy time according to their needs. After the set time is reached, the heating module automatically stops working, avoiding safety hazards caused by prolonged overheating.

[0043] Size Design: The overall dimensions of the seat cushion are 40cm x 40cm. This size meets the needs of most patients and is also compatible with common chair and bed sizes. The diameter of the hollow area has been carefully calculated and verified in practice, set between 10-15cm to ensure complete coverage of the anus and wound area, achieving effective pressure relief and protection.

[0044] Working principle: The post-hemorrhoid surgery special cushion is used as follows:

[0045] Placement and alignment: When using the cushion, the patient should place it stably on a suitable support surface such as a chair or bed, and carefully adjust the position of the cushion to ensure that the hollow area in the center of the cushion is accurately aligned with the anus, thereby achieving effective pressure relief and protection for the wound.

[0046] Airbag 41 Adjustment: Through a specially designed inflation and deflation device, patients can easily operate the airbags 41 on both sides of the seat cushion according to their own perception of comfort. By appropriately increasing or decreasing the amount of gas in the airbags 41, the patient can achieve the most suitable seat cushion height and firmness for their physical condition and comfort requirements.

[0047] Activate thermal therapy: Start thermal therapy module 5 and set the appropriate heat therapy temperature using the control buttons on the module or the control interface connected to external devices. This temperature range has been verified through professional medical research and practice, providing patients with the best thermal therapy effect without damaging the skin, promoting local blood circulation and wound healing.

[0048] Cleaning and Maintenance: After each use, the surface of the cushion should be cleaned promptly. Use a mild detergent and a soft, damp cloth to gently wipe the surface of the cushion to remove stains and bacteria, keeping the cushion clean and hygienic and providing good conditions for the next use.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
