Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a protective dressing for high exudative wound incisions. Background Art

[0002] At present, facial minimally invasive surgery or injection beauty is widely used, so choosing a wound dressing that is beneficial to wound healing and disease recovery has become one of the important issues that the people and medical workers are increasingly concerned about. The physiological, psychological, and economic acceptance of the patient for the dressing is also very important. With the progress of society and the improvement of people's quality of life, patients' requirements for wound healing and comfort have also increased accordingly. However, postoperative wound compression generally uses traditional gauze compression to stop bleeding. In this way, although the operation of medical staff is simple and convenient, the patient's compression is prone to displacement or falling off, and there will be a series of situations that affect the effect of facial surgery and injections, such as uneven strength control.

[0003] For example, a medical dressing is proposed in publication number CN204636717U, which includes an absorbent pad and a sticky pad made of a sticky material; the sticky pad is arranged on the outer edge of the absorbent pad, and the absorbent pad is placed on the inner side thereof, and a plurality of tear strips are arranged on the sticky pad, and the plurality of tear strips can be detachably adhered to the sticky pad to form a separation structure for protecting the stickiness of the sticky pad. The medical dressing of the utility model is simple to use, and can effectively compress and stop bleeding, protect the wound surface, prevent infection, and promote healing after minimally invasive facial surgery or injection. At the same time, it has many advantages such as shape fitting, simple use, easy to carry, good breathability, and reliable efficacy.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned medical dressings still have the following problems: the above-mentioned device can effectively compress and stop bleeding, protect the wound surface, prevent infection and promote healing after minimally invasive facial surgery or injection, but since it is impossible to add medicine to the inside of the dressing when using it on the wound, the healing effect of the wound is affected, resulting in a certain degree of limitation in the practicality of the device. Utility Model Content

[0005] The utility model proposes a protective dressing for high exudative wound incisions, which solves the problem in the related art that when the dressing is used on the wound, drugs cannot be added into the dressing, which affects the healing effect of the wound:

[0006] The technical solution of the utility model is as follows: a protective dressing for high exudative wound incisions, comprising a drainage fluid collection bag, a catheter is arranged in the middle of the front of the drainage fluid collection bag, a drainage fluid discharge valve is arranged in the middle of the catheter, a drainage hose is arranged inside the drainage fluid collection bag, the rear end of the catheter is connected to the drainage hose, and a breathable and waterproof outer film is arranged on the surface of the drainage fluid collection bag.

[0007] Preferably, a one-way liquid guide film is provided at the bottom of the drainage fluid collection bag, and a waterproof coating is sprayed on the surface of the one-way liquid guide film.

[0008] Preferably, a first antibacterial biological particle layer is provided at the bottom of the one-way liquid guide membrane. The first antibacterial biological particle layer is amoxicillin particles, which can kill bacteria by inhibiting the synthesis of cell walls.

[0009] Preferably, a first two-way flow guide membrane is disposed at the bottom of the first antibacterial biological particle layer, and a two-way channel is disposed inside the first two-way flow guide membrane to increase the flow rate of the fluid.

[0010] Preferably, a second antibacterial biological particle layer is disposed at the bottom of the first two-way flow-guiding membrane, and a second two-way flow-guiding membrane is disposed at the bottom of the second antibacterial biological particle layer.

[0011] Preferably, a skin self-adhesive edge is provided at the bottom of the second two-way flow guide membrane, and an antibacterial coating slip film is provided at the middle of the bottom end of the second two-way flow guide membrane.

[0012] Preferably, the thickness of the skin self-adhesive edge is higher than the thickness of the antibacterial coating synovial membrane, and the skin self-adhesive edge surrounds the outer side of the antibacterial coating synovial membrane.

[0013] Preferably, an adhesive paper is provided at the bottom of the second two-way flow-guiding membrane.

[0014] The working principle and beneficial effects of the utility model are:

[0015] 1. In this embodiment, a drainage fluid collection bag, a drainage hose, a catheter, and a drainage fluid discharge valve are provided. The traditional protective dressing can only protect the wound to prevent the wound from contacting water and causing wound infection, which affects the wound recovery effect. By opening the drainage fluid discharge valve, the drug is added to the catheter. The drug is added to the drainage fluid collection bag and flows through the drainage hose to the bottom of the breathable and waterproof outer membrane, so that the drug contacts the wound. When the drug is replaced, the drainage fluid discharge valve is opened, and the drug overflows through the catheter, thereby replacing the drug. The structure is simple and the use is more convenient. With the assistance of the drug, the healing rate of the wound is accelerated, and the practicality of the device is improved.

[0016] 2. In this embodiment, a unidirectional liquid guide membrane, a first antibacterial biological particle layer, a first bidirectional flow guide membrane, a second antibacterial biological particle layer, and a second bidirectional flow guide membrane are provided. The infused drugs will pass through the unidirectional liquid guide membrane respectively. Since the unidirectional liquid guide membrane can only conduct unidirectional flow, the drug liquid can only flow to the wound, so that the drug liquid contacts the wound, and the bacteria grown in the wound are mixed with the drug and retained in the first bidirectional flow guide membrane and the second bidirectional flow guide membrane. The first antibacterial biological particle layer is arranged in the middle of the unidirectional liquid guide membrane and the first bidirectional flow guide membrane, and the second antibacterial biological particle layer is located in the middle of the first bidirectional flow guide membrane and the second bidirectional flow guide membrane. The mixture of bacteria and drugs will be sterilized under the action of the first antibacterial biological particle layer and the second antibacterial biological particle layer, thereby avoiding bacterial growth, reducing wound infection, and improving the safety of the device.
