Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical skin preparation knife, in particular to a disposable medical underarm skin preparation knife. BACKGROUND

[0002] Skin preparation refers to the removal of hair from the surgical site and the cleaning of the body surface for patients undergoing surgery. The purpose of skin preparation is to reduce the number of skin bacteria and the infection rate of surgical incisions without damaging the integrity of the skin. Generally, the skin preparation area is 15-30 cm around the surgical area, and in special cases, the skin preparation area needs to be expanded. Breast surgery, upper limb surgery, and chest surgery all require skin preparation under the armpit.

[0003] In the prior art, disposable skin preparation knives are commonly used. For example, CN216372309U discloses a medical skin preparation knife, and the transparent handle can facilitate observation of the solution usage state in the liquid storage cavity, thereby improving the operation efficiency of medical personnel. For example, CN216781926U discloses a skin preparation knife with lubricating function, which does not require the use of cotton swabs for application, allowing the scraper to be fully lubricated for skin preparation operation. However, there are still some problems with this skin preparation knife with lubricating function in the prior art: 1) Generally, this commonly used clinical skin preparation knife has a rectangular double-sided blade head of about 4.3 cm and a width of 2.5 cm, which is not suitable for the physiological curvature of various parts of the human body; 2) For some thin patients, the armpit has little fat and the armpit is concave, so the rectangular skin preparation knife cannot enter the armpit, and the hair under the armpit cannot be removed, which may cause surgical incision infection and prolong the hospitalization time of the patient. Therefore, there is an urgent need for a skin preparation knife device that can highly adapt to armpit skin preparation. SUMMARY

[0004] To solve the above problems, the present scheme provides a disposable medical underarm skin preparation knife. The hollow spherical blade head designed to fit the curvature of the armpit, equipped with arc-shaped blades and liquid outlets, and the handle containing lubricating liquid, solves the problem that the existing skin preparation knife is not suitable for the physiological curvature of the human armpit, and reduces the risk of surgical incision infection.

[0005] To achieve the above purpose, the present scheme specifically adopts the following technical means:

[0006] A disposable medical underarm skin preparation knife includes a hollow spherical blade head that fits the curvature of the armpit, the outer surface of the blade head is equipped with several rows of arc-shaped blades that match its contour, and a plurality of liquid outlets are arranged between the blades; the blade head and the cavity handle are integrally formed; the handle contains lubricating liquid, and a piston push rod is built-in.

[0007] Further, the arc-shaped blade is downwardly oriented and forms an angle with the tangent line of the hollow spherical cutter head, which helps to reach the deep armpit and better remove the hard-to-reach hair.

[0008] Further, the handle comprises a curved section, which can enhance the operation convenience.

[0009] Further, the arc-shaped blades are arranged in rows on the outer surface of the cutter head.

[0010] Compared with the prior art, the disposable medical armpit skin preparation cutter has the following beneficial technical effects:

[0011] The hollow spherical cutter head is designed to fit the armpit curve and can better adapt to the shape of the human armpit depression, and the arc-shaped blades are adapted to the contour shape of the outer surface of the cutter head, which ensures comprehensive and effective hair removal and completes the skin preparation.

[0012] The liquid outlet holes arranged between the blades allow the lubricating liquid to be uniformly distributed between the blades and the skin, which helps to reduce the irritation and damage to the skin during skin preparation and improves the safety of skin preparation. The cutter head and the handle are integrally formed and are in communication with each other, and the handle is provided with a piston push rod, which can push the lubricating liquid during use to ensure that the blades are always lubricated during skin preparation. The handle comprises a curved section, which allows medical personnel to perform skin scraping operation in a slightly horizontal position without needing to wrap their hands to the bottom of the armpit, significantly improving the operation convenience and efficiency.

[0013] The armpit skin preparation cutter is easy to operate and safe and reliable, which not only improves the skin preparation efficiency and safety but also reduces the damage to the skin and the risk of surgical incision infection, and has good effect on the armpit skin preparation work of patients with thin body type.

[0020] The advantages and effects of the present application can be easily understood by those skilled in the art from the disclosure of the present application. The present application can also be implemented or applied in different specific embodiments, and various modifications or changes can be made to the details in the present application based on different views and applications without departing from the spirit of the present application. It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0021] Please refer to Figs. 1-5 The head 1 of the disposable medical underarm skin preparation knife adopts a hollow spherical shape with a diameter of 2.5 cm. The spherical design can better adapt to the curve of the human underarm, thereby reducing damage to the skin during skin preparation. In addition, the outer surface of the head 1 is uniformly provided with three rows of arc-shaped blades 2, which match the contour of the head 1, thereby enabling smoother skin preparation.

[0022] Between the blades 2, there are 9-12 tiny liquid outlets 3 for releasing lubricating liquid during skin preparation. The lubricating liquid serves to reduce skin friction, reduce the risk of damage, and maintain the lubricating state between the blades and the skin. The head 1 and the handle 4 are integrally formed, and the above design can ensure the stability and safety of the entire skin preparation process. The handle 4 is provided with a pattern on the outer surface to prevent slipping when held. The handle 4 contains lubricating liquid and is provided with a piston push rod 5 for pushing the release of lubricating liquid. In this way, the blades always maintain a lubricating state during the entire skin preparation process, thereby reducing the risk of skin damage and surgical incision infection.

[0023] In the present embodiment, the arc-shaped blades 2 are oriented downward, forming an inclination angle of about 5-10° with the tangent line of the hollow spherical head 1. The above design helps the blades to penetrate deep into the underarm, better removing hard-to-reach hair. In addition, the head 1 is made of transparent plastic material, which allows the user to intuitively see the lubricating liquid condition inside the head, ensuring safety and hygiene during use. At the same time, the transparent plastic material needs to have sufficient mechanical strength and wear resistance.

[0024] The handle 4 can be made of medical-grade plastic, such as polycarbonate (PC) or other medical-grade plastic with good chemical resistance and impact resistance. In this way, the handle can withstand various environmental and operating conditions during long-term use, ensuring its stability and durability. The disposable medical underarm skin preparation knife of the present application can be integrally formed by injection molding or other methods during production, which has high production efficiency and low cost.

[0025] In addition, a protective cover can be designed on the periphery of the head 1 to form a protective layer. The protective cover can be covered on the head when not in use to prevent the blade from being contaminated by the outside world and ensure hygiene before use. The protective cover can also prevent accidental injury to the blade when not in use. The material of the protective cover can be selected from medical grade plastic or silicone material to ensure its safety and durability.

[0026] In specific use, the protective cover of the head is removed, and the medical staff only needs to attach the head 1 to the armpit of the patient, use the arc-shaped design of the blade to fit the skin, and remove the hair by the contact between the blade and the skin and the shaving of the handle 4. During the skin preparation process, the outlet hole 3 will continuously release lubricating liquid to keep the blade and the skin lubricated and reduce the damage to the skin. At the same time, the curved section of the handle 4 makes the head 1 deviate from the straight line of the handle, allowing the medical staff to shave the skin in a slightly horizontal position without having to turn their hands to the bottom of the armpit, thereby improving the convenience and efficiency of the operation.

[0027] The disposable medical armpit skin preparation knife provided by the utility model can better adapt to the physiological arc of the armpit of the human body through the spherical head, improve the skin preparation efficiency and safety, reduce the damage to the skin, and reduce the risk of surgical incision infection. In particular, it has significant advantages in the armpit skin preparation work for patients with a thin body type.
