It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention. The terms "first," "second," "third," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

An embodiment of the present application provides a wound protection device, please refer to fig. 1 and fig. 2, where the wound protection device includes a fixing portion 1 and a protrusion portion 2 disposed on a surface of the fixing portion 1. The boss 2 has a receiving space therein for receiving articles to be used. For example, the boss 2 is connected to the fixing portion 1.

The boss 2 includes a lower bottom surface and an outer surface, wherein the lower bottom surface is constituted by an area of the fixing portion 1 covered by the boss 2; the outer surface is a part of the protruding part 2 protruding from the fixing part 1.

In this embodiment, at least one first hole 3 is disposed on an outer surface of the protruding portion 2, and the first hole 3 is in fluid communication with the accommodating space. For example, the first hole 3 may be formed on the outer surface of the boss 2 except for the lower bottom surface, as shown in fig. 1. The height of the first hole 3 on the boss 2 can be set according to requirements. Preferably, the first hole 3 is arranged at or near the top of the boss 2, so that the wound protection device can contain more drugs.

Specifically, the first hole 3 may be used as a drug injection hole, and may be used to inject a desired drug, such as a liquid drug, into the accommodating space.

In this embodiment, at least one second hole 4 (not clearly shown in the figure due to an angle) is formed in the lower bottom surface of the protruding portion 2, and the second hole 4 is in fluid communication with the accommodating space. For example, the second hole 4 may be a rectangular slot. The second hole 4 can allow the drug in the accommodating space to be transferred to the wound surface so as to act on the wound surface. Conceivably, the first holes 3 and the second holes 4 can also be used together as ventilation holes, so as to improve ventilation of the wound area, so as to ensure that the wound area has sufficient oxygen.

In some embodiments, the wound protection device is a transparent structure. In this way, the shape of the wound and the conditions in the receiving space of the wound protection device can be observed visually. For example, in practical application, the application type or other experimental operations can be adjusted according to the real-time change of the wound surface, and meanwhile, the change condition of the wound surface covered by the wound surface protection device and the use condition of the medicament in the accommodating cavity can be visually observed.

The shape of the fixation part 1 may be determined according to the wound surface. The edge of the fixing part 1 is of an arc-shaped structure, so that the wound area and soft tissues around the wound area can be prevented from being damaged. For example, in some embodiments, the outer circumference of the fixation portion 1 is circular.

In some embodiments, the diameter of the fixing portion 1 is 15-25 mm. For example, the diameter of the fixing part 1 may be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25 mm.

In some embodiments, the lower bottom surface of the boss 2 is circular or polygonal.

In some embodiments, the protrusions 2 have a bottom dimension of (8-10) mm by (3-5) mm and a height of 4-6 mm. The size of the boss 2 may be determined according to actual circumstances. For example, the size of the lower bottom surface of the boss 2 is 9mm by 4mm, and the height of the boss 2 is 5 mm.

In one embodiment, the boss 2 is preferably a truncated cone structure.

In some embodiments, the protrusions 2 are of a trapezoidal structure. In this case, the outer surface of the boss 2 includes four side surfaces and an upper bottom surface, and the first hole 3 is located on the four side surfaces and/or the upper bottom surface. The number of the first holes 3 can be determined according to actual requirements. In addition, the position of the first hole 3 is preferably close to the upper bottom surface, i.e. the position far away from the fixing part 1 as much as possible, so that the accommodating space can accommodate more medicine.

In an embodiment, referring to fig. 1 or fig. 2, the cross section of the protrusion 2 is an isosceles trapezoid, and includes an upper bottom surface, a side surface, and the lower bottom surface. It can be seen that the four side surfaces and the upper bottom surface may be provided with first holes 3 for injecting a medicine or venting air. The second hole 4 is a rectangular slotted hole and is arranged on the lower bottom surface of the boss 2; further, the second hole 4 is disposed near a boundary between the protruding portion 2 and the fixing portion 1.

In one embodiment, the size of the upper bottom surface of the boss 2 may be 6mm by 2 mm.

In some embodiments, the material of the wound protection device is soft rubber. It is conceivable that the soft rubber is easily penetrated by a needle or the like. Thus, when the wound surface protection device is applied to a rat experiment, a line can penetrate through the position of the fixing part 1 and be fixed in the wound surface area if necessary.

In some embodiments, the wound protection device may be a unitary structure.

The utility model also provides an application of surface of a wound protection device in the rat experiment specifically as follows:

when a rat back wound experiment is carried out, the edge of the fixing part 1 is sewn on the skin around the rat back wound, so that the phenomena of adhesion and shrinkage of a wound model can be effectively prevented, and the relative cleanness of the wound is kept; meanwhile, experimental drugs are injected through the first holes 3 (drug injection holes) formed in the protruding portions 2, and the drugs flow into the wound surface of the rat through the first holes 3 and the second holes 4. The wound surface protection device not only can conveniently inject medicine into the wound surface of a rat, but also can ventilate oxygen to the wound surface of the rat, so that the accuracy of the experimental data is improved.

In conclusion, when a rat back wound experiment is carried out, the fixing part 1 at the bottom is sewn on the skin around the rat back wound, so that the phenomena of adhesion and shrinkage of a wound model can be effectively prevented, and the relative cleanness of the wound can be kept; the medicine injection holes 3 formed in the protruding portions 2 can conveniently inject medicine to the wound surface of a rat and can also introduce oxygen to the wound surface of the rat, and therefore accuracy of experimental data is improved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
