Technical Field
The utility model relates to a medical equipment, especially a last negative pressure wound therapeutic instrument equipment.
Background
Many different types of wound dressings are known for assisting the healing process in humans or animals. These different types of wound dressings include many different types of materials and layers, such as gauze, pads, foam pads, or multi-layer wound dressings. Topical negative pressure "TNP" therapy, sometimes referred to as vacuum assisted closure, negative pressure wound therapy or reduced pressure wound therapy, is widely recognized as a beneficial mechanism for increasing the rate of wound healing. Such treatments are applicable to a wide variety of wounds, such as incisions, open wounds, abdominal wounds, and the like.
TNP therapy aids in wound closure and healing by reducing tissue edema, promoting blood flow, stimulating the formation of granulation tissue, removing excess exudate, and may reduce bacterial load and thus infection of the wound. And TNP therapy can reduce external disturbance of the wound and promote faster healing.
The prior art has the defects and reasons that:
the existing negative pressure therapeutic products realize the principle of negative pressure: detecting the wound dressing position through an air pressure sensor; adjusting the negative pressure value at the wound dressing by controlling the negative pressure pump to be switched on and off in stages; namely, the system presets an ideal negative pressure value and a negative pressure threshold value, and when the wound dressing position reaches the ideal negative pressure value, the negative pressure pump stops working; when the negative pressure at the wound dressing exceeds a negative pressure threshold, the negative pressure pump stops working.
The wound dressing is in a non-completely closed environment, namely the negative pressure value at the wound dressing exceeds the negative pressure threshold value in a staged manner, so that the negative pressure pump needs to be started in a staged manner, the time period is about 1.5-3 hours, the wound dressing is determined according to the sealing condition, and the starting time is about 2-4 minutes each time; this kind of control scheme causes the negative pressure value that wound dressing department stir range great on the one hand, and on the other hand, the patient needs to receive the noise influence that the negative pressure pump work produced in stage time.
In addition, negative pressure at the position of the existing wound dressing is applied discontinuously, the negative pressure is maintained unstably, and the hidden trouble of negative pressure monitoring failure exists in the working process of equipment.
