Description

A small therapeutic instrument for wound repair

technical field

The utility model relates to the field of related technical equipment of medical instruments, in particular to a small therapeutic instrument for wound repair.

Background technique

As the prevalence of various chronic diseases increases year by year, the related chronic wounds such as pressure sores, diabetic feet, and venous lower extremity ulcers also show a high incidence. Wound repair itself is a complicated process, affected by various factors, the repair process of many difficult-to-heal wounds is very long. For the treatment and treatment of acute and chronic wounds, most of them still adopt the method of bandaging for primary care in the early stage, and the form is single. For infected refractory wounds, gauze wet compresses are often used for treatment. This method requires frequent dressing changes, tearing and pain during dressing changes, and hinders normal activities during the dressing process, which brings burdens to medical staff and creates pain for patients. Painful and even slows down wound healing.

Among the existing wound treatment methods, the common one is drip therapy. Wound healing using a liquid (an infusion) to irrigate a wound is called instillation therapy, and this type of device is also called an infusion therapy device. The drip therapy device treats wounds with the aid of fluid irrigation.

A significant advantage of instillation therapy over conventional wound treatment is the ability to eliminate bandage changes and to continuously use the instillation solution for irrigation. The instillation solution can stay in the wound for a certain period of time under appropriate conditions and can be sucked away with the help of negative pressure. Instillation therapy in this way can help wound debridement and create a wound environment that can promote wound healing.

In the drip treatment of wounds there is always the problem of dispensing the infusion solution. When the delivered dose of infusion solution is insufficient, the flushing effect will not be achieved and the supply of healing active ingredients will be insufficient, which will not sufficiently obtain the expected effect of promoting wound healing. The delivery of large doses of infusion solution will cause overpressure inside the wound bandage, which will endanger the wound, and will hinder the fit of the bandage on the wound, increasing the possibility of wound damage, causing patient pain and increased labor costs.

The existing method of controlling the amount of infusion solution, such as introducing the infusion solution and observing and controlling the swelling of the wound dressing, has certain disadvantages. The assessment of the timing of interruption of the infusion solution is realized through the subjective observation of the user, so it cannot be accurately judged for various situations. At the same time, most of the existing infusion therapy instruments have no temperature control for the infusion liquid, so that the liquid medicine cannot exert the best therapeutic effect; or the control method is inconvenient. The common method is to heat the closed container, which is large in size and is not suitable for small instruments. .

The function of a common negative pressure therapy device is to suck out the wound fluid and form a negative pressure environment. For the infusion of medicine, the infusion bag is usually set at a height higher than the absorber, and gravity is used to make the treatment liquid flow into the absorber along the flushing pipe. The body cannot realize the flow adjustment of the treatment liquid flexibly and conveniently, and the instrument is bulky and inconvenient to carry.

As another disadvantage, during the treatment process of the existing negative pressure therapeutic apparatus, its heating module heats the outer wall of the infusion pipeline, and in the flushing mode, the flow rate of the liquid medicine is faster, so there is a disadvantage of insufficient heating. affect the therapeutic effect.

In recent years, traditional Chinese medicine has been widely used clinically in the treatment of chronic refractory wounds and infected wounds because of its comprehensive treatment mechanism and reasonable dosage form advantages. Compound Cortex Phellodendron Liquid is the first new surgical traditional Chinese medicine preparation in China. It is based on the theory of traditional Chinese medicine and selects a successful traditional prescription. Stuffed into the sinus tract or applied externally, etc.

Modern studies have shown that Compound Cortex Phellodendron Liquid not only has the functions of antibacterial, anti-infection, promoting wound healing, and protecting the nervous system, but also enhances the phagocytosis of monocytes and macrophages, improves non-specific immunity, and reduces the intensity of local inflammatory reactions. Has obvious curative effect. Clinical practice has shown that it has a broad-spectrum antibacterial effect, can quickly eliminate wound redness, promote the elimination of purulent secretions, reduce secretions, accelerate the drying of erosive surfaces, the growth of granulation tissue and wound healing.

Based on above-mentioned reasons, how to design a kind of therapeutic apparatus that can cooperate with the instillation of compound Phellodendron Phellodendri, is the problem that those skilled in the art urgently need to solve.
