Description
Technical Field
[0001] This invention belongs to the field of medical device technology, specifically a head surgery skin preparation device. Background Technology
[0002] Prep is a crucial preparatory step before head surgery. Its core purpose is to shave the hair in the surgical area to reduce the risk of hair falling into the wound and causing infection during the operation, while also providing a clear view for the surgical procedure.
[0003] Currently, the routine preoperative skin preparation procedure for head surgery in clinical practice mostly involves medical staff using handheld traditional electric shavers to shave the hair in the surgical area. While this type of traditional shaver can meet basic hair removal needs and is easy to operate, it is widely used in clinical practice. However, during the shaving process, the shaved hair tends to scatter everywhere, not only contaminating the surgical environment but also potentially landing in the surgical wound area, increasing the probability of postoperative infection. Furthermore, cleaning up the scattered hair is a laborious task that consumes a significant amount of time for medical staff. Therefore, improvements are needed. Summary of the Invention
[0004] The purpose of this invention is to provide a head surgery preparation device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a head surgical skin preparation device, comprising an electric shaver, a razor fixedly mounted at the end of the electric shaver, an adsorption head fixedly connected to the outer surface of the electric shaver and located directly above the razor, a connecting hose fixedly connected to the top of the adsorption head, an installation box fixedly sleeved on the outer surface of the other end of the connecting hose, a movable tube movably sleeved on the inner wall of the connecting hose, a suction pipe movably sleeved on the outer surface of the movable tube, a fan fixedly connected to one end of the suction pipe, one end of the fan fixedly connected to the outside of the installation box, an exhaust pipe fixedly connected to the right side of the fan, the suction pipe and the exhaust pipe communicating with each other, and a filter screen fixedly installed inside the suction pipe.
[0006] Preferably, a dual-axis motor is fixedly connected to the top of the mounting box, and a rotating shaft is fixedly sleeved at the other end of the output shaft of the dual-axis motor. A rotating rod is fixedly sleeved on the outer surface of the rotating shaft, and a round rod is slidably connected to the inner surface of the rotating rod. There are two round rods, and the inner sides of the two round rods are fixedly connected to the outer surface of the movable tube. A collection box is movably installed at the bottom of the inner cavity of the mounting box.
[0007] Preferably, the outer side of the mounting box is provided with two sliding grooves, and the inner surface of the two sliding grooves is slidably connected to the outer surface of the two round rods respectively.
[0008] Preferably, a lifting motor located to the left of the dual-axis motor is fixedly connected to the top of the mounting box, and a transmission shaft is fixedly sleeved at the other end of the output shaft of the lifting motor, and a cam is fixedly sleeved on the outer surface of the transmission shaft.
[0009] Preferably, a T-shaped rod is movably sleeved on the inner surface of the top of the mounting box, and a brush is fixedly connected to the bottom of the T-shaped rod, with the brush located directly above the filter screen.
[0010] Preferably, the top of the brush is fixedly connected to a spring, and there are two springs, the tops of which are fixedly connected to the top of the inner cavity of the mounting box.
[0011] Preferably, a limiting rod is fixedly connected to the top of the mounting box, and the outer surface of the limiting rod is movably sleeved with the inner surface of the T-shaped rod.
[0012] Preferably, there are two limiting rods, the two limiting rods are the same size, and the two limiting rods are symmetrical about the center of the T-shaped rod.
[0013] Preferably, the brush surface of the brush is at the same horizontal plane as the filter screen.
[0014] The beneficial effects of this invention are as follows:
[0015] 1. This invention, by setting up an adsorption head, connecting hose, movable tube, suction tube, and fan, allows medical staff to hold the electric shaver close to the patient's head and precisely shave the hair in the surgical area with the help of the razor when the electric shaver is started. At the same time, the fan is started to create a negative pressure adsorption channel. Under the continuous negative pressure, the adsorption head, connecting hose, movable tube, and suction tube work together to capture the shaved hair in real time. The hair is filtered and intercepted by the filter screen and adheres to the surface of the screen. The purified air is then smoothly discharged through the exhaust pipe, eliminating the source of shaved hair from spreading and contaminating the surgical environment. This completely avoids the risk of hair falling into the wound and causing infection, and greatly improves the cleanliness and safety of head preparation procedures.
[0016] 2. This invention, through the configuration of a dual-axis motor, rotating shafts, rotating rods, round rods, and a collection box, enables the two rotating shafts to rotate when the dual-axis motor is running. As the rotating rods rotate, their inner surfaces continuously compress the two round rods, causing them to move smoothly horizontally. This, in turn, pulls the movable tube to retract horizontally into the suction tube, releasing the blockage of the adsorption passage. At this time, the hair intercepted on the filter screen naturally falls into the collection box below under its own gravity, achieving automatic hair collection. Hair can be easily cleaned without disassembling the device, significantly saving the operation time of medical staff and improving the efficiency of skin preparation.
[0017] 3. This invention, by setting up a lifting motor, a cam, a T-shaped rod, a brush, and springs, ensures that when the lifting motor is running, the transmission shaft drives the cam to rotate. As the cam rotates, its protruding part contacts the top of the T-shaped rod and generates a downward thrust, pushing the T-shaped rod to move the brush downwards synchronously. The brush adheres to the surface of the filter screen, thoroughly scraping off any attached residual hair and collecting it in the collection box below. As the brush moves downwards, it simultaneously stretches two springs. When the cam protrusion separates from the T-shaped rod, the springs, under their restoring force, quickly reset the T-shaped rod and brush, achieving rapid up-and-down scraping. This ensures the filter screen is clean, prevents hair residue from affecting the negative pressure adsorption effect, and guarantees the continuous and stable operation of the skin preparation process.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] like Figures 1 to 7 As shown, this embodiment of the invention provides a head surgery skin preparation device, including an electric shaver 1, a razor 2 fixedly mounted at the end of the electric shaver 1, an adsorption head 3 fixedly connected to the outer surface of the electric shaver 1 located directly above the razor 2, a connecting hose 4 fixedly connected to the top of the adsorption head 3, an installation box 5 fixedly sleeved on the outer surface of the other end of the connecting hose 4, a movable tube 6 movably sleeved on the inner wall of the connecting hose 4, a suction pipe 7 movably sleeved on the outer surface of the movable tube 6, a fan 8 fixedly connected to one end of the suction pipe 7, one end of the fan 8 fixedly connected to the outside of the installation box 5, an exhaust pipe 9 fixedly connected to the right side of the fan 8, the suction pipe 7 and the exhaust pipe 9 are connected, and a filter screen 10 is fixedly installed inside the suction pipe 7.
[0028] When the electric hair shaver 1 is started, the medical staff takes the electric hair shaver 1 and shaves the hair off the patient's head under the action of the razor 2. At the same time, the fan 8 is started. Under the action of negative pressure, the suction head 3, connecting hose 4, movable tube 6 and suction tube 7 will be used to absorb the shaved hair. The hair is filtered through the filter screen 10 and then adsorbed on its surface. The filtered air is then discharged through the exhaust pipe 9.
[0029] The top of the mounting box 5 is fixedly connected to a dual-axis motor 11. The other end of the output shaft of the dual-axis motor 11 is fixedly sleeved with a rotating shaft 12. The outer surface of the rotating shaft 12 is fixedly sleeved with a rotating rod 13. The inner surface of the rotating rod 13 is slidably connected with a round rod 14. There are two round rods 14. The inner sides of the two round rods 14 are fixedly connected to the outer surface of the movable tube 6. A collection box 15 is movably installed at the bottom of the inner cavity of the mounting box 5.
[0030] When the dual-axis motor 11 is running, the two rotating shafts 12 will drive the two rotating rods 13 to rotate. As the two rotating rods 13 rotate, their inner surfaces will squeeze the two round rods 14 and drive them to move horizontally. This will drive the movable tube 6 to move horizontally and retract into the air suction tube 7, releasing the sealing effect on the tube. At this time, the hair adsorbed on the surface of the filter screen 10 will fall into the collection box 15 under the action of gravity and be collected, thus achieving the purpose of automatic hair collection.
[0031] The mounting box 5 has two sliding grooves 16 on its outer side. The inner surfaces of the two sliding grooves 16 are slidably connected to the outer surfaces of the two round rods 14 respectively.
[0032] The design of the two slides 16 serves to limit and guide the round rod 14, ensuring the stability of the horizontal movement of the round rod 14.
[0033] The top of the mounting box 5 is fixedly connected to a lifting motor 17 located to the left of the dual-axis motor 11. The other end of the output shaft of the lifting motor 17 is fixedly sleeved with a transmission shaft 18, and a cam 19 is fixedly sleeved on the outer surface of the transmission shaft 18.
[0034] When the lifting motor 17 is running, it will cause the drive shaft 18 to drive the cam 19 to rotate.
[0035] Among them, a T-shaped rod 20 is movably sleeved on the inner surface of the top of the mounting box 5, and a brush 21 is fixedly connected to the bottom of the T-shaped rod 20. The brush 21 is located directly above the filter screen plate 10.
[0036] As the cam 19 rotates and contacts the top of the T-shaped rod 20, it will push the T-shaped rod 20 and the brush 21 downward to scrape the hair remaining on the surface of the filter screen 10 into the collection box 15 for collection.
[0037] Among them, the top of the brush 21 is fixedly connected to a spring 22, and there are two springs 22. The top of both springs 22 is fixedly connected to the top of the inner cavity of the mounting box 5.
[0038] When the brush 21 moves downward, it will stretch the two springs 22. When the cam 19 separates from the T-shaped rod 20, the T-shaped rod 20 and the brush 21 will quickly return to their original positions under the restoring force of the two springs 22, thus achieving the purpose of quickly scraping the surface of the filter screen 10 by going down and up.
[0039] Among them, the top of the mounting box 5 is fixedly connected to a limiting rod 23, and the outer surface of the limiting rod 23 is movably sleeved with the inner surface of the T-shaped rod 20.
[0040] The design of the limit rod 23 serves to limit the T-shaped rod 20, ensuring the stability of the lifting and lowering movement of the T-shaped rod 20.
[0041] There are two limit rods 23, and the two limit rods 23 are the same size and are symmetrical about the center of the T-shaped rod 20.
[0042] The design of two limit rods 23 provides better limiting and guiding effect for the T-shaped rod 20.
[0043] The brush surface of the brush 21 is at the same horizontal plane as the filter screen 10.
[0044] This design allows the brush 21 to come into contact with the surface of the filter plate 10, thereby removing residual hair from the surface of the filter plate 10.
[0045] Working principle and usage process:
[0046] When preparing the patient's head, the electric shaver 1 and the blower 8 are first turned on. Then, the medical staff take the electric shaver 1 and shave the hair off the patient's head under the action of the razor 2. At the same time, under the action of negative pressure, the suction head 3, connecting hose 4, movable tube 6 and suction tube 7 will be used to absorb the shaved hair. After the hair is filtered by the filter plate 10, it is adsorbed on the surface. The filtered air is then discharged through the exhaust tube 9, which prevents the shaved hair from scattering everywhere.
[0047] After shaving, stop the fan 8 and start the dual-axis motor 11, causing the two rotating shafts 12 to drive the two rotating rods 13 to rotate. As the two rotating rods 13 rotate, their inner surfaces will squeeze the two round rods 14 and drive them to move horizontally. This will cause the movable tube 6 to move horizontally and retract into the suction tube 7, releasing the sealing effect on the tube. At this time, the hair adsorbed on the surface of the filter plate 10 will fall into the collection box 15 under the action of gravity and be collected. This achieves the purpose of automatic hair collection, and the hair can be cleaned without disassembly.
[0048] Then, the lifting motor 17 is started, causing the drive shaft 18 to drive the cam 19 to rotate. As the cam 19 rotates and contacts the top of the T-shaped rod 20, it will push the T-shaped rod 20 and the brush 21 to move downwards, scraping the hair remaining on the surface of the filter screen 10 into the collection box 15 for collection. The downward movement of the brush 21 will stretch the two springs 22. When the cam 19 separates from the T-shaped rod 20, the spring force of the two springs 22 will restore the T-shaped rod 20 and the brush 21 to quickly return to their original positions. This achieves the purpose of quickly scraping the surface of the filter screen 10 from bottom to top, avoiding hair residue on the surface of the filter screen 10 from affecting the negative pressure effect.
