Description

Technical Field

[0001] This invention relates to the field of medical engineering technology, and more specifically, to a skin surface cleaning and disinfection device. Background Technology

[0002] With the increasing health awareness and social responsibility of the people, more and more people are starting to have regular physical examinations and donate blood. Whether it is a physical examination or blood donation, blood needs to be drawn. Human skin contains a lot of bacteria, viruses and dirt. In order to prevent the needle from being contaminated after contacting the skin and bringing the contaminant into the body and causing infection after piercing the skin, the skin must be cleaned and disinfected before blood is drawn.

[0003] The current cleaning and disinfection method involves medical staff applying iodine or other disinfectant solutions to the skin surface with cotton swabs. While this method is effective, it is labor-intensive and burdensome during large-scale physical examinations and blood donation drives. Furthermore, manual disinfection carries the risk of oversight, especially during periods of high patient volume or when medical staff work continuously for extended periods. This can lead to small areas being missed during the process, affecting the effectiveness of disinfection and increasing the risk of infection. Summary of the Invention

[0016] The blade is positioned opposite to the cotton pad;

[0017] The end of the cotton pad hangs down through the drop groove.

[0018] Furthermore, a recessed groove is provided in the center of the soft pillow;

[0019] The recessed groove is elliptical in shape;

[0021] Furthermore, the dust removal mechanism includes two suspension rods connected to the bottom of the extended platform plate and located on both sides of the round head piece, a lower air outlet connected to the two suspension rods, a fan installed on the top of the base, a single-ended sealing pipe with one end connected to the air outlet of the fan and the other end penetrating through the right-angled upright plate, a second flexible hose connecting the lower air outlet to the single-ended sealing pipe, and a protective cover set on the top of the base and the back of the right-angled upright plate;

[0022] The fan is located inside the protective cover;

[0023] The lower air inlet is the same width as the soft pillow.

[0024] Furthermore, the masking mechanism also includes a fourth electric push rod installed on the bottom of the epitaxial platform plate, and a clamping bar connected to the output end of the fourth electric push rod;

[0025] The clip is attached to one side of the drop groove and faces the cotton sheet.

[0026] Furthermore, the masking mechanism also includes a second storage tank disposed on the epitaxial platform plate, an absorbent cotton block embedded on the epitaxial platform plate, a cotton strip disposed on the top of the clamp strip, and an absorbent cotton rod with one end inserted into the second storage tank and the other end inserted into the absorbent cotton block.

[0027] The absorbent cotton block is attached to the cotton strip;

[0028] The top surface of the cotton swab is flush with the surface of the outer platform plate;

[0029] The second storage tank contains water.

[0030] Furthermore, the ash removal mechanism also includes an oblique guide edge installed at the lower blowhole opening.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] The skin surface cleaning and disinfection device uses a first electric push rod and two second electric push rods as the basic driving force and relies on a right-angle vertical plate to smoothly drive the outer platform plate to move freely in the horizontal and vertical directions, so that the spraying mechanism, covering mechanism and dust removal mechanism can move and work as required to ensure automatic cleaning and disinfection of the skin surface.

[0033] This skin surface cleaning and disinfection device provides a good reference point through a soft cushion, making it easy to accurately and quickly place the arm in the appropriate position. This ensures that the skin surface to be disinfected corresponds to the spraying mechanism, the covering mechanism, and the dust removal mechanism, thus guaranteeing the smooth and effective execution of subsequent cleaning and disinfection work.

[0034] This skin surface cleaning and disinfection device can spray disinfectant in the form of water mist onto the skin surface to be disinfected through a spraying mechanism. It can also expand the spraying area by slightly oscillating, thereby ensuring that the skin surface to be disinfected is evenly and comprehensively sprayed with disinfectant, effectively preventing some small areas from being missed and not being cleaned and disinfected.

[0035] This skin surface cleaning and disinfection device uses a dust removal mechanism to first sweep the skin surface to be disinfected at an angle, thereby blowing away all the dust on the skin and cleaning it before spraying disinfectant, thus ensuring the cleanliness of the skin surface during disinfection and ensuring the disinfection effect.

[0036] This skin surface cleaning and disinfection device, through the cooperation of a covering mechanism and a re-spraying mechanism, can cover the skin surface after spraying disinfectant and continue spraying disinfectant, thereby completing the wet compress of the skin surface to be disinfected. This further prevents some small areas from being missed in cleaning and disinfection, ensuring disinfection effect, effectively reducing the risk of infection. At the same time, the longer-lasting disinfection effect allows the cleaning and disinfection steps to be carried out in advance, so as to complete the pre-disinfection in batches in an orderly manner, thereby effectively reducing the workload of medical staff and effectively improving efficiency.

Detailed Implementation

[0054] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0055] like Figure 1-14 As shown, a skin surface cleaning and disinfection device includes: a base 1, a soft cushion 2 disposed on the base 1, a right-angled plate 3 integrally connected to the base 1 and located on one side of the soft cushion 2, a horizontal bar 4 vertically slidably mounted on the right-angled plate 3, an extended platform plate 5 horizontally slidably inserted into the horizontal bar 4, a spraying mechanism 6 and a masking mechanism 7 disposed on the extended platform plate 5, a dust removal mechanism 8 disposed on the extended platform plate 5, the right-angled plate 3 and the base 1, a first electric push rod 9 mounted on the horizontal bar 4 and the output end of the first electric push rod 9 connected to the extended platform plate 5, and two second electric push rods 10 vertically disposed on the base 1 and located between the soft cushion 2 and the right-angled plate 3, and the output ends of the two second electric push rods 10 respectively connected to the bottom of the horizontal bar 4 from both ends;

[0056] The spraying mechanism 6, the covering mechanism 7, and the dust-removing mechanism 8 are all partially centered directly above the soft cushion 2, wherein:

[0057] The soft cushion 2 is suitable for forming a placement reference so that the skin surface to be disinfected can be accurately placed;

[0058] The dust removal mechanism 8 is adapted to blow on the skin surface to be disinfected to remove the dust on it;

[0059] The spraying mechanism 6 is adapted to evenly release disinfectant onto the skin surface to be disinfected, so as to cover the skin surface to be disinfected;

[0060] The covering mechanism 7 and the spraying mechanism 6 are adapted to automatically cover and wet-apply disinfected skin surfaces. This skin surface cleaning and disinfection device uses a first electric push rod 9 and two second electric push rods 10 as the basic driving force and relies on the right-angle upright plate 3 to smoothly drive the extended platform plate 5 to move freely in the horizontal and vertical directions. This allows the spraying mechanism 6, covering mechanism 7, and dust-removing mechanism 8 to operate as required, ensuring automatic cleaning and disinfection of the skin surface. The soft cushion 2 provides a good reference point, facilitating accurate and quick placement of the arm in a suitable position, ensuring that the skin surface to be disinfected corresponds to the spraying mechanism 6, covering mechanism 7, and dust-removing mechanism 8, guaranteeing the smooth and effective execution of subsequent cleaning and disinfection. The spraying mechanism 6 sprays the disinfectant as a water mist onto the skin surface to be disinfected and can expand the spraying area with slight oscillations, ensuring thorough disinfection. The disinfectant is sprayed evenly and comprehensively onto the skin surface, effectively preventing any small areas from being missed during disinfection. The dust removal mechanism 8 first uses an oblique blowing motion to sweep away all dust from the skin before the disinfectant is sprayed, ensuring the cleanliness of the skin surface and guaranteeing the disinfection effect. With the cooperation of the covering mechanism 7 and the spraying mechanism 6, the skin surface is covered after the disinfectant is sprayed, and the disinfectant continues to be sprayed, completing a wet compress of the skin surface to be disinfected. This further prevents any small areas from being missed during disinfection, ensuring the disinfection effect and effectively reducing the risk of infection. The longer-lasting disinfection effect allows for pre-disinfection steps to be performed in batches and in an orderly manner, effectively reducing the workload of medical staff and improving efficiency.

[0061] Optionally, the spraying mechanism 6 includes a lifting plate 61 connected to the front side of the extended platform plate 5, a first storage tank 62 disposed on the lifting plate 61, a water pump 63 disposed on the extended platform plate 5, a first hose 64 with one end connected to the outlet of the water pump 63 and the other end penetrating downward through the extended platform plate 5, a spray head 65 connected to the other end of the first hose 64, and a delivery pipe 66 with one end connected to the inlet of the water pump 63 and the other end connected to the first storage tank 62;

[0062] The first storage tank 62 contains disinfectant. Simultaneously, two second electric actuators 10 are driven to pull the horizontal bar 4 up and down on the right-angled vertical plate 3, while the first electric actuator 9 is driven to push and pull the outer platform plate 5 laterally. This causes the spray head 65 to gradually approach the skin surface to be disinfected. The driving of the two second electric actuators 10 and the first electric actuator 9 stops when the spray head 65 is close to the skin surface. Then, the water pump 63 is activated to extract the disinfectant from the first storage tank 62. Finally, the disinfectant is converted into a water mist and sprayed onto the skin surface through the spray head 65. During spraying, the first electric actuator 9 is driven again at a uniform speed to move the outer platform plate 5, ensuring that the disinfectant is sprayed evenly and comprehensively onto the skin surface while effectively reducing the workload of medical staff.

[0063] Optionally, the spraying mechanism 6 further includes an annular body 67 mounted on the spray head 65, a round head member 68 and a half-frame plate 69 connected to the bottom of the extended platform plate 5, wherein the half-frame plate 69 is located behind the round head member 68, an arc-shaped through groove 691 is formed on the round head member 68, a first motor 692 is provided on the half-frame plate 69, a circular plate 693 is mounted on the output shaft of the first motor 692, a slot 694 is formed on the circular plate 693, and a rod 695 connected to the annular body 67;

[0064] The rod 695 passes sequentially through the arc-shaped through groove 691 and the slot 694. When spraying disinfectant, the first motor 692 is activated to drive the circular plate 693 to rotate back and forth slightly, so that the rod 695 swings synchronously in the arc-shaped through groove 691. This causes the spray head 65 to spray the disinfectant in a back-and-forth swinging state, thereby expanding the spraying area and ensuring that the skin surface to be disinfected is evenly and comprehensively sprayed with disinfectant, effectively preventing some small areas from being missed and not being cleaned and disinfected.

[0065] Optionally, the masking mechanism 7 includes two upright arms 71 spaced apart on the extension platform plate 5, a spindle 72 rotatably mounted on the two upright arms 71, with one end of the spindle 72 passing through one of the upright arms 71, a support platform 73 mounted on the extension platform plate 5, a second motor 74 disposed on the support platform 73, with the output end of the second motor 74 connected to the outwardly penetrating end of the spindle 72, a third electric push rod 75 disposed on the extension platform plate 5, a blade 76 attached to the surface of the extension platform plate 5 and embedded in one of the upright arms 71, with the blade 76 connected to the output end of the third electric push rod 75, a cotton sheet 77 wound on the spindle 72, and a drop groove 78 opened on the extension platform plate 5 and located between the two upright arms 71;

[0066] The blade 76 is positioned opposite to the cotton pad 77;

[0067] The cotton pad 77 hangs down through the drop groove 78. After the spraying mechanism 6 has fully sprayed the disinfectant, the cotton pad 77 is moved to contact the skin surface by the first electric push rod 9 and the two second electric push rods 10. Then, the first electric push rod 9 is driven again to translate the outer platform plate 5 and at the same time, the second motor 74 is started to drive the spindle 72 to rotate, gradually releasing the cotton pad 77 wound on the spindle 72, so that the cotton pad 77 is gradually laid flat on the skin surface until the cotton pad 77 can completely cover the skin surface to be disinfected. Then the first electric push rod 9 and the second motor 74 are stopped. Then, the third electric push rod 75 is driven to move the blade 76 forward at a constant speed. The cotton pad 77 is cut open using blade 76, allowing the section of cotton pad 77 to fall completely onto the skin surface. Then, disinfectant is sprayed onto the cotton pad 77 again via spraying mechanism 6, wetting it and providing continuous wet compress disinfection to the skin surface. This further prevents any small areas from being missed during cleaning and disinfection, ensuring effective disinfection and reducing the risk of infection. The longer-lasting disinfection effect allows for pre-treatment of multiple people's skin before blood draws, further reducing the workload of medical staff and improving efficiency.

[0068] Optionally, a recessed groove 21 is provided in the center of the soft pillow 2;

[0069] The recessed groove 21 is elliptical;

[0070] The soft cushion 2 is equipped with a sensor 22, and the emitting end face of the sensor 22 is flush with the inner bottom surface of the recessed groove 21. Blood is usually drawn from the elbow vein. When a person places their arm on the soft cushion 2, the recessed groove 21 provides a reference point, that is, the elbow joint is placed on the recessed groove 21, thereby accurately locating the skin to be disinfected on the soft cushion 2. This ensures that the person places their arm accurately and quickly as required, and thus ensures that the surface of the skin to be disinfected corresponds to the spraying mechanism 6, the covering mechanism 7, and the dust removal mechanism 8, so as to complete the cleaning and disinfection of the surface of the skin to be disinfected smoothly, orderly, and effectively. The sensor 22 is used to transmit information to the spraying mechanism 6, the covering mechanism 7, and the dust removal mechanism 8 after the person places their arm on the soft cushion 2 as required, so as to control them to start working in an orderly manner for cleaning and disinfection. For example, it controls the spraying mechanism 6, the covering mechanism 7, and the dust removal mechanism 8 to work in an orderly manner after the arm is placed on the soft cushion 2 for five or ten seconds.

[0071] Optionally, the dust removal mechanism 8 includes two suspension rods 81 connected to the bottom of the extended platform plate 5 and located on both sides of the round head piece 68, a lower air outlet 82 connected to the two suspension rods 81, a fan installed on the top of the base 1, one end of which is connected to the air outlet of the fan and the other end of which passes through the single-ended sealing pipe 84 of the right-angle upright plate 3, a second flexible hose 85 connecting the lower air outlet 82 and the single-ended sealing pipe 84, and a protective cover 86 provided on the top of the base 1 and the back of the right-angle upright plate 3;

[0072] The fan is located inside the protective cover 86;

[0073] The lower nozzle 82 is the same width as the soft pillow 2. Before the spraying mechanism 6 sprays disinfectant onto the skin, the lower nozzle 82 is adjusted to a position close to the skin surface by the first electric push rod 9 and two second electric push rods 10. Then, the fan is started, and the lower nozzle 82 starts blowing air under the sequential transmission of the single-head sealing tube 84 and the second flexible tube 85. At the same time, the first electric push rod 9 is started to make the lower nozzle 82 move horizontally at a uniform speed, thereby blowing away the skin surface. This ensures that all the dust on the skin is blown away and cleaned before spraying disinfectant onto the skin, ensuring the cleanliness of the skin surface during disinfection and ensuring the disinfection effect.

[0074] Optionally, the masking mechanism 7 further includes a fourth electric push rod 79 mounted on the bottom of the extension platform plate 5, and a clamping strip 791 connected to the output end of the fourth electric push rod 79;

[0075] The clamping strip 791 is attached to one side of the drop groove 78 and faces the cotton pad 77. Before the cotton pad 77 is cut by the blade 76, the fourth electric push rod 79 is driven to push the clamping strip 791 forward until the clamping strip 791 presses the cotton pad 77 against the outer platform plate 5 in the drop groove 78, and the cotton pad 77 is fixed in place before it is cut. This ensures that it can be successfully cut open, while preventing the cotton pad 77 from being dragged away from the skin surface to be disinfected due to the lack of restraint when it is cut directly without restraint. This would destroy the covering state of the cotton pad 77 on the skin surface at the predetermined position and affect the subsequent continuous wet compress disinfection.

[0076] Optionally, the covering mechanism 7 further includes a second storage tank 792 disposed on the outer extension platform plate 5, an absorbent cotton block 793 embedded on the outer extension platform plate 5, a cotton strip 794 disposed on the top of the clamping strip 791, and an absorbent cotton rod 795 with one end inserted into the second storage tank 792 and the other end inserted into the absorbent cotton block 793.

[0077] The absorbent cotton block 793 is attached to the cotton strip 794;

[0078] The top surface of the cotton sliver 794 is flush with the surface of the extended platform plate 5;

[0079] The second storage tank 792 contains water. The water in the second storage tank 792 is continuously absorbed by the absorbent cotton swab 795 and transferred to the absorbent cotton block 793. The absorbent cotton block 793 then transfers the water to the cotton strip 794, keeping the cotton strip 794 moist. When the clamp 791 holds the cotton pad 77 in place, the cotton strip 794 is simultaneously squeezed, which quickly transfers the water it contains to the cotton pad 77. This rapidly wets and spreads the water to the corresponding area on the cotton pad 77, ensuring that the ends of each section of the cotton pad 77 are moist to a certain extent. This increases the weight of the cotton pad 77 and keeps the ends of the cotton pad 77 hanging down, ensuring that the cotton pad 77 can smoothly contact the skin surface and be gradually laid flat on the skin surface for wet compress.

[0080] Optionally, the dust removal mechanism 8 also includes an oblique guide edge 87 installed at the opening of the lower air outlet 82. The oblique guide edge 87 guides the air obliquely to ensure that the dust on the skin is completely blown away, so as to prevent the dust from falling back onto the skin after being blown up by the straight wind, resulting in incomplete dust removal.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
