[0002] Skin preparation is a common tool used in surgery. It is used to shave the hair at the surgical site to facilitate the operation. The purpose of skin preparation is to reduce the number of skin bacteria without damaging the integrity of the skin and reduce the infection rate of the incision after surgery. Hair from the armpits, abdomen, thighs, perineum, etc. needs to be removed during surgical skin preparation.

[0003] In addition to using a skin preparation knife, skin preparation also requires the use of soap liquid and a soap liquid application tool. Before skin preparation, the soap liquid needs to be squeezed onto the skin preparation area to lubricate and soften the hair, facilitate skin preparation and protect the skin. Since the items used are all separate, preparation and use are not very convenient. Some patents disclose skin preparation bags that package skin preparation items together, such as ZL202020670796.2, ZL202022272092.2, ZL201721562421.9, etc., but in these patents, the skin preparation knife, soap liquid and soap liquid application tool still exist separately and are not integrated together.

[0004] Therefore, a skin preparation knife with built-in lubricant is designed. When preparing skin, only the skin preparation knife is needed, which makes skin preparation more convenient. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a skin preparation knife with self-lubricating liquid. When preparing skin, only the skin preparation knife needs to be prepared, which facilitates the skin preparation.

[0015] The present invention will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present invention can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present invention more complete and to fully convey the concept of the present invention to those skilled in the art.

[0016] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0017] The drawback that the skin preparation knife, soap liquid and soap liquid application tool in the prior art still exist separately. After careful analysis, the inventor found that the reason for the above technical problems is mainly that the structure of the skin preparation knife is similar to that of a razor, and it only has the function of shaving hair. However, in addition to using the skin preparation knife, soap liquid and soap liquid application tool are also needed in the skin preparation process. Before skin preparation, soap liquid needs to be squeezed to the skin preparation area to play a role in lubrication and softening hair, which is convenient for skin preparation and can protect the skin. Since the items used are all separate, it is not very convenient to prepare and use. Based on the above analysis, the inventor designed a skin preparation knife with its own lubricant. When preparing skin, only the skin preparation knife needs to be prepared, which is convenient for skin preparation.

[0018] like Figures 1 to 3As shown, in the first embodiment of the utility model, a skin preparation knife with self-lubricating liquid comprises a handle 1, a knife seat 2, a soft bottle body 3 and a blade 4, the knife seat 2 is arranged at the front end of the handle 1, the blade 4 is installed on the knife seat 2, the knife seat 2 is provided with a liquid outlet 21, one end of the handle 1 is provided with a flow hole 11, and the other end is connected to the soft bottle body 3, and a flow channel connecting the flow hole 11 and the soft bottle body 3 is provided in the handle 1. The middle part of the soft bottle body 3 is concave to form a groove 31, the upper part of the soft bottle body 3 is covered with a hard shell 32, and a non-slip layer is applied on the hard shell 32.

[0019] A connecting hole 22 is provided in the center of the knife holder 2, and an internal thread is provided in the connecting hole 22, and an external thread matching the internal thread is provided on the knife handle 1; the liquid outlet 21 is provided on the inner wall of the connecting hole 22. A sealing ring 23 is provided on the top wall of the connecting hole 22, and the knife handle 1 is inserted into the connecting hole 22 and pressed under the sealing ring 23. The knife holder 2 and the knife handle 1 are detachably connected, and the knife handle 1 can be removed, and the soap liquid can be injected from the outlet hole 11 of the knife handle 1. After the skin preparation is completed, the knife handle 1 can be removed for reuse, thereby reducing resource waste. The knife holder 2 and the knife handle 1 are connected by threads, and the knife handle 1 is pressed on the sealing ring 23. When the soft bottle body 3 is squeezed, the soap liquid in the soft bottle body 3 is not easy to overflow from the connection between the knife holder 2 and the knife handle 1.

[0020] Among them, a rollable ball 5 is provided on the top of the knife seat 2, and a liquid outlet gap is provided between the ball 5 and the knife seat 2, and the liquid outlet gap is connected to the liquid outlet hole 21. There are multiple liquid outlet holes 21, and multiple liquid outlet holes 21 are evenly arranged around the knife handle 1. When there are not many hairs to be removed, only a small amount of lubricant needs to be applied, and the skin preparation knife is directly inverted, and the ball 5 is brought into contact with the patient's skin and rolled on it. The lubricant will be evenly applied to the patient's skin, which can achieve lubrication and save lubricant, and the patient's comfort is improved. When a large amount of lubricant needs to be applied, the soft bottle body 3 can be squeezed to speed up the speed of the lubricant coming out and improve work efficiency.

[0021] The blade 4 includes a short blade 41 and a long blade 42, and the short blade 41 and the long blade 42 are respectively arranged on both sides of the blade holder 2. The blade holder 2 is trapezoidal and has a short side and a long side. The short blade 41 is installed on the short side of the blade holder 2, and the long blade 42 is arranged on the long side of the blade holder 2. The short blade 41 is used to remove hair from the narrower parts of the perineum or armpits; the long blade 42 is used to remove hair from wider parts such as the abdomen and thighs, which can meet the requirements of shaving in wider and narrower spaces at the same time, and has strong applicability. The blade holder 2 is trapezoidal, and the length of the long side corresponds to the length of the long blade 42, and the length of the short side corresponds to the length of the short blade 41; so that the blade holder 2 can still stretch well in narrow places, and it is not easy to affect the short blade 41 to remove hair from the narrower parts of the perineum or armpits.

[0022] The method of using the skin preparation knife with self-lubricating liquid is as follows:

[0023] When shaving and skin preparation are required, first, the handle 1 is disassembled and the soap solution is injected from the outlet hole 11 of the handle 1. Secondly, the skin preparation knife is inverted, and the lubricating liquid enters the outlet hole 21 under the action of gravity and is applied to the patient's skin using the ball 5. If a large amount of lubricating liquid is needed, the soft bottle body 3 is squeezed to speed up the speed of the lubricating liquid coming out and improve work efficiency. Finally, the operator grabs the hard shell 32 and shaves. When the operator grabs the hard shell 32, it is not easy to squeeze the soft bottle body 3 when shaving, and the lubricating liquid is not easy to overflow.

[0024] All of the above embodiments are illustrative rather than restrictive. Various modifications or variations made by those skilled in the art to the above-described specific embodiments under the concept of the present utility model should all be within the protection scope of the present utility model.
