Description

Self-inflating balloon applicator

technical field

The utility model belongs to the technical field of medical devices, and relates to a wound applicator, in particular to a self-inflating airbag applicator for subcutaneous active bleeding wounds.

Background technique

At present, after local trauma or large-area skin flap peeling operations, such as radical mastectomy, it is easy to cause extensive bleeding under the skin of the wound. Therefore, it is necessary to apply local pressure to stop bleeding to reduce hematoma and even shock reaction caused by subcutaneous bleeding. In clinical treatment of wounds, synthetic fiber dressings are often used. These types of dressings have no compressive effect and are not fixed. When there is a lot of wound exudate, it will adhere to the dressing and cause secondary damage to the wound. Elastic tourniquets and bandages are used. Or gauze or the like for pressure winding, which often needs to be removed due to the needs of extremity blood supply or dressing change. Repeating the process is cumbersome and increases the clinical workload. Repeated use of certain pressurized materials can also increase the probability of contamination. In order to achieve a good hemostasis effect, doctors usually wrap and pressurize with a large pressure. If the bandaging time is too long, the patient will feel local discomfort, try to break free, and even affect the local blood supply. In addition, the currently used medical sterile dressings are mainly synthetic fiber dressings. In addition to the simple wound protection function, the hemostatic effect is limited. Some patients also cause allergies due to long-term compression of the dressing and close contact with the skin, which affects the hemostatic effect.

The compression airbag port is connected to the inflatable one-way valve, and is connected to the microinflatable device through an inflatable tube. The self-inflating airbag applicator provides unidirectional air supply for the compression airbag by operating the micro-inflating device, so as to achieve hemostasis of the local subcutaneous active bleeding wound.

Preferably, the dressing layer is connected with the plastic film A, and is arranged within the boundary of the compression balloon.

Preferably, the adhesive layer adopts medical tape to adhere to the wound. The adhesive layer is pasted on the non-wound place of the patient when in use, and is covered with a layer of isolation film for protection when not in use.

Preferably, the dressing layer is made of chitin fiber non-woven fabric.

Preferably, the miniature inflatable device adopts a miniature hand-pinch inflatable pump.

Further, an air inlet is provided on the surface of the miniature hand-pinch air pump, and the air inlet is designed in a "meter" character structure. The miniature hand-kneaded air pump is recommended to be of a cuboid structure and made of silicone material.

Preferably, a medical tape layer is attached to the lower surface of the miniature hand-pinch air pump, which is protected by an isolation film when not in use, and can be pasted on the non-wound place of the patient when in use.

Compared with the prior art, the beneficial effect of the present invention is that the compression airbag in the self-inflating airbag application of the present invention is plastic-sealed and fixed between the plastic film A and the plastic film B. The medical sterile dressing layer is made of chitin fiber non-woven fabric, which has the functions of antibacterial and anti-inflammatory, dehumidification and pain relief, and skin allergy prevention, which is conducive to the healing of wounds on the patient's surface. The miniature hand-kneaded air pump is a cuboid structure and is made of silicone material, which has good resilience. The degree of compression on the wound can be adjusted by controlling the number of times of pressing the micro-pinch air pump. There is an air inlet on the upper surface of the miniature hand-kneaded air pump. The air inlet is designed with a "m"-shaped structure. This design allows the outside air to enter the air pump smoothly and prevents large particles from being brought in. The lower surface of the miniature hand-pinch air pump is attached with a medical tape layer, which is protected by an isolation film when not in use, and can be pasted on the non-wound area of the patient when it is in use.
