Description

Technical Field

[0001] This application relates to the technical field of medical devices, and specifically relates to a surgical nursing appliance. Background Art

[0002] Surgery is a scientific field that explores the origin, evolution law, clinical manifestations, diagnostic methods, preventive measures, and treatment plans of surgical diseases. It mainly relies on means such as surgical cutting and repair to treat diseases. Currently, when a patient is injured, especially in cases of large-area burns, medical staff need to prepare a large number of cotton balls, as well as disinfectants such as normal saline and iodophor, in order to clean and disinfect the wound area. When dealing with a large wound, since doctors constantly throw away the used cotton balls and replace them with new cotton balls dipped in medicine, it is easy for doctors to forget whether a certain position of the wound has been wiped.

[0003] The "Surgical Nursing Dressing Change Device" with the application number "202010917410.8" uses a driving and winding method to drive the cotton cloth, so that it is not necessary to constantly throw away the used cotton balls, thus avoiding the situation where doctors forget whether a certain position of the wound has been wiped.

[0004] However, since the cotton cloth is in a compacted state of winding before use, during the winding process, the cotton cloth strip is affected by external forces, and the gaps between the fibers are compressed, resulting in the whole becoming tight. The wound after burns is usually more sensitive, and wiping with the tight cotton cloth may exacerbate the pain and discomfort of the wound. If the cotton cloth is not soft enough, it may also cause friction to the wound during the wiping process, further damaging the wound tissue, thus affecting the comfort of dressing change.

[0037] Embodiment 1

[0038] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a surgical nursing dressing - changing device, including a housing 1. A storage wheel 2 is provided at the top end inside the housing 1. The housing 1 is divided into a front housing and a rear housing, and the front housing and the rear housing can be detachably connected by screws. A winding wheel 3 is provided on the right side inside the housing 1. A cotton cloth strip 4 is wound inside the storage wheel 2. One end of the cotton cloth strip 4 away from the storage wheel 2 passes out from the left side of the housing 1 and is wound around the outside of the housing 1, and one end of the cotton cloth strip 4 away from the storage wheel 2 passes into the housing 1 from the bottom right side of the housing 1 and is fixedly wound inside the winding wheel 3. A combing component 5 for fluffing the cotton cloth strip 4 is provided on the left part of the housing 1. The combing component 5 includes a mounting shell 51 fixedly connected to the left part of the housing 1. Through - slots 52 for the cotton cloth strip 4 to pass through are opened at both the top and bottom ends on the left part of the mounting shell 51. A rotating shaft 53 is rotatably connected inside the mounting shell 51. A combing wheel 54 is fixedly connected to the outer wall of the rotating shaft 53. A combing plate 55 is fixedly connected to the outer wall of the combing wheel 54. A driving component 6 is provided at the rear end of the housing 1. The driving component 6 includes a bent frame 61 fixedly connected to the rear end of the housing 1. A motor 62 is fixedly connected to the rear end of the bent frame 61. The output shaft of the motor 62 passes through the bent frame 61 and is fixedly connected to a first sprocket 63. A small shaft 65 is slidably connected inside the winding wheel 3. The outer wall of the small shaft 65 is rotatably connected to the housing 1 and its rear end passes out from the housing 1 and is fixedly connected to a third sprocket 66. A circular shaft 67 is rotatably connected to the rear end of the mounting shell 51. A second sprocket 64 is fixedly connected to the outer wall of the circular shaft 67. A chain 68 is connected between the second sprocket 64, the first sprocket 63 and the third sprocket 66 for transmission.

[0039] By adopting the above technical solution, a roller is rotatably connected to the outer side of the housing 1 for supporting the cotton strip 4 and facilitating the reduction of the resistance of the movement of the cotton strip 4. The side of the cotton strip 4 close to the housing 1 in this solution is made of a firm and highly water-permeable fabric, and the side of the cotton strip 4 away from the housing 1 is made of soft cotton floss. During use, the housing 1 is held by holding the hand-held frame fixedly connected to the rear end of the housing 1, and the cotton strip 4 at the bottom of the housing 1 is brought into contact with the skin of the patient's burn.

[0040] When it is necessary to replace the cotton strip 4 at the wiping position after wiping for a period of time, the output shaft of the motor 62 rotates, causing the first sprocket 63 to rotate. At this time, under the driving action of the chain 68, the third sprocket 66 and the second sprocket 64 rotate, so that the stub shaft 65 drives the winding wheel 3 to rotate. At this time, the winding wheel 3 winds the cotton strip 4, thereby replacing the cotton strip 4 at the bottom of the housing 1. Under the traction of the cotton strip 4, the storage wheel 2 also rotates accordingly.

[0041] It should be noted that the storage wheel 2 is detachable from the housing 1, and the winding wheel 3 can also be detached from the stub shaft 65 of the housing 1. The detachable part between the storage wheel 2 and the housing 1 is rotatable, and a rubber particle material is provided at the rotating part, and the resistance provided by the rubber particle material is less than the pulling force provided by the rotation of the motor 62.

[0042] When replacing the cotton strip 4 at the bottom of the housing 1, since the first sprocket 63 on the output shaft of the motor 62 rotates, under the driving action of the chain 68, the second sprocket 64 and the round shaft 67 rotate. Under the meshing action of the first gear 610 and the second gear 69, the rotating shaft 53 rotates accordingly. When the rotating shaft 53 rotates, the combing wheel 54 located inside the mounting shell 51 can be rotated. At this time, the plurality of combing plates 55 rotate to comb the wound and compacted cotton strip 4, making the side of the compacted cotton strip 4 away from the housing 1 softer, thereby reducing the friction of the cotton strip 4 on the wound when wiping the wound and reducing the damage to the wound tissue, thereby improving the comfort of dressing change.

[0043] Specifically, as Figures 2 to 5 shown, the rear end of the rotating shaft 53 passes through the rear part of the mounting shell 51 and is fixedly connected with a first gear 610. The outer wall of the round shaft 67 is fixedly connected with a second gear 69 at the rear end of the second sprocket 64. The first gear 610 meshes with the second gear 69.

[0044] By adopting the above technical solution, when replacing the cotton strip 4 at the bottom of the housing 1, the winding wheel 3 rotates in the clockwise direction, and the cotton strip 4 at the left part of the housing 1 moves downward. Under the action of the round shaft 67, the first gear 610 and the second gear 69, the first gear 610 and the rotating shaft 53 rotate in the direction opposite to that of the winding wheel 3. The rotating shaft 53, the carding wheel 54 and the carding plate 55 rotate in the counterclockwise direction, so that when the cotton strip 4 moves downward, the carding plate 55 combs the cotton strip 4 upward, further improving the carding effect on the cotton strip 4, thereby further improving the softness of the cotton strip 4 and further improving the comfort of dressing change.

[0045] Specifically, as Figure 2 and Figure 5 shown, a first magnetic ring 10 is fixedly connected to the front end of the outer wall of the rotating shaft 53, a second magnetic ring 11 is fixedly connected to the front end of the carding wheel 54, a bump 12 is fixedly connected to the rear end of the carding wheel 54 in an annular array, the rear end of the bump 12 is inclined, and a limiting strip 13 is fixedly connected to the inner rear end of the mounting shell 51. The magnetic poles of the side of the second magnetic ring 11 close to the first magnetic ring 10 are the same.

[0046] By adopting the above technical solution, since the magnetic poles of the side of the second magnetic ring 11 close to the first magnetic ring 10 are the same, in the initial state, according to the principle of like poles repelling each other, the carding wheel 54 is located relatively far from the first magnetic ring 10. At this time, the front end of the limiting strip 13 is close to the right side of the carding wheel 54. As the rotating shaft 53 rotates, the bump 12 will rotate. The bump 12 approaches the limiting strip 13 and is limited by the limiting strip 13, so that the carding wheel 54 and the carding plate 55 move slightly forward against the magnetic force, and then the carding wheel 54 and the carding plate 55 can swing in the front-back direction during carding, further improving the carding effect on the cotton strip 4, thereby further improving the comfort during dressing change.

[0047] Specifically, as Figures 2 to 7As shown in the figure, a medicine adding component 7 is arranged at the inner bottom end of the shell 1. The medicine adding component 7 includes a medicine storage frame 71 fixedly connected to the inner bottom end of the shell 1. A medicine adding pipe 72 is fixedly inserted at the top of the medicine storage frame 71. The medicine adding component 7 further includes an empty slot 73 opened at the bottom of the shell 1. A discharge slot 74 is opened at the bottom of the shell 1 below the empty slot 73. A lifting rod 75 is fixedly connected to the top of the medicine storage frame 71 at the rear end of the medicine adding pipe 72. A small frame 76 is fixedly connected to the bottom of the lifting rod 75. An extrusion plate 77 is fixedly connected to the bottom of the small frame 76. A plugging rod 78 is fixedly connected to the bottom of the extrusion plate 77. A pipe fitting 79 is arranged between the inside of the medicine storage frame 71 and the empty slot 73. The outer part of the pipe fitting 79 is fixedly connected to the shell 1. An inlet hole 710 is opened at the top of the shell 1. A plugging hole 711 is opened at the bottom of the shell 1. A chamfer is opened at the bottom of the plugging rod 78. The diameter of the plugging hole 711 is adapted to the plugging rod 78. The diameter of the extrusion plate 77 is larger than that of the inlet hole 710. A long plate 712 is fixedly connected to the top of the lifting rod 75. A spring 713 is fixedly connected between the long plate 712 and the medicine storage frame 71. The output shaft of the motor 62 penetrates into the inside of the shell 1 and is fixedly connected with a cam 9.

[0048] By adopting the above technical solution, when the medicine adding component 7 is used to add the liquid medicine for wiping into the cotton strip 4, the top of the medicine adding pipe 72 extends out from the front end of the shell 1. Before use, at this time, the bottom of the plugging rod 78 does not block the plugging hole 711. The liquid medicine is added into the inside of the medicine storage frame 71 from the medicine adding pipe. In the initial state, the protruding part of the cam 9 faces upward. Under the elastic force of the spring 713, the top of the extrusion plate 77 blocks the inlet hole 710, and the liquid medicine will not enter the inside of the pipe fitting 79. When the output shaft of the motor 62 rotates to replace the cotton strip 4 at the bottom of the shell 1, the cam 9 rotates accordingly. When the protruding side of the cam 9 rotates close to the long plate 712 and squeezes the long plate 712, the long plate 712 moves downward, and the spring 713 is in a compressed state, so that the lifting rod 75 moves downward, the small frame 76 moves downward accordingly, the extrusion plate 77 no longer blocks the inlet hole 710, the liquid medicine enters the inside of the pipe fitting 79, and the plugging rod 78 is inserted into the inside of the plugging hole 711, and the liquid medicine cannot be discharged from the plugging hole 711. When the cam 9 continues to rotate and its protruding end faces upward, under the elastic force of the spring 713, the lifting rod 75 moves upward, the small frame 76 moves upward accordingly, the extrusion plate 77 blocks the inlet hole 710. At this time, the liquid medicine enters the inside of the empty slot 73 from the plugging hole 711 and is discharged from the discharge slot 74. Such a design can realize the automatic addition of the liquid medicine to moisten the cotton strip 4.

[0049] It should be noted that when replacing the cotton strip 4 at the bottom of the shell 1, the output shaft of the motor 62 rotates one week.

[0050] Specifically, as Figures 6 to 7 shown, by adopting the above technical solution, slow-down components 8 are arranged on both sides of the bottom of the long board 712. The slow-down components 8 include through rods 81 fixedly connected to both sides of the bottom of the long board 712. Sleeve rods 82 are fixedly connected to the outer walls of the through rods 81. The bottom of the through rod 81 extends into the interior of the sleeve rod 82 and is fixedly connected with a round plate 83. The bottom of the round plate 83 is inclined, and inclined strips 84 are fixedly connected to the interior of the sleeve rod 82.

[0051] By adopting the above technical solution, when the extrusion plate 77 moves downward, the bottom of the plugging rod 78 starts to insert into the interior of the plugging hole 711. The inclined strip 84 is inclined downward and elastic. When the long board 712 is pressed and moves downward, the round plate 83 moves downward, facilitating the squeezing open of the inclined strip 84. When the long board 712 resets under the elastic force of the spring 713, under the restricting action of the inclined strip 84, the upward movement and reset speed of the long board 712 can be slowed down, so that after the cotton cloth strip 4 is replaced, the bottom of the plugging rod 78 completely leaves the plugging hole 711, realizing the addition of the liquid medicine after the cotton cloth strip 4 is replaced, and reducing the waste of the liquid medicine.

[0052] Working principle: When in use, hold the hand-held frame fixedly connected to the rear end of the housing 1 and bring the cotton cloth strip 4 at the bottom of the housing 1 into contact with the skin of the burn of the patient. When it is necessary to replace the cotton cloth strip 4 at the wiping position after wiping for a period of time, rotate the output shaft of the motor 62, so that the first sprocket 63 rotates. At this time, under the driving action of the chain 68, the third sprocket 66 and the second sprocket 64 rotate, so that the small shaft 65 drives the winding wheel 3 to rotate. At this time, the winding wheel 3 winds the cotton cloth strip 4, so as to replace the cotton cloth strip 4 at the bottom of the housing 1. Under the traction action of the cotton cloth strip 4, the storage wheel 2 also rotates accordingly. When replacing the cotton cloth strip 4 at the bottom of the housing 1, since the first sprocket 63 on the output shaft of the motor 62 rotates, under the driving action of the chain 68, the second sprocket 64 and the round shaft 67 rotate. Under the meshing action of the first gear 610 and the second gear 69, the rotating shaft 53 rotates accordingly. When the rotating shaft 53 rotates, the combing wheel 54 located inside the mounting shell 51 can be rotated. At this time, the plurality of combing plates 55 rotate to comb the cotton cloth strip 4 that is wound and compacted, so that the side of the cotton cloth strip 4 away from the housing 1 becomes softer.

[0053] In the initial state, according to the principle of like charges repelling each other, the combing wheel 54 is located relatively far from the first magnetic ring 10. At this time, the front end of the limiting strip 13 is close to the right side of the combing wheel 54. As the rotating shaft 53 rotates, the convex block 12 will rotate. The convex block 12 approaches the limiting strip 13 and is limited by the limiting strip 13, causing the combing wheel 54 and the combing plate 55 to move slightly forward in the direction of the front end against the magnetic force. Thus, when combing, the combing wheel 54 and the combing plate 55 can swing in the front-back direction, further improving the effect of combing the incoming cotton strip 4, and thus further improving the comfort during dressing change.

[0054] When the output shaft of the motor 62 rotates to replace the cotton strip 4 at the bottom of the housing 1, the cam 9 rotates accordingly. When the protruding side of the cam 9 rotates close to the long plate 712 and squeezes the long plate 712, the long plate 712 moves downward, the spring 713 is in a compressed state, the lifting rod 75 moves downward, and the small frame 76 moves downward accordingly. The pressing plate 77 no longer blocks the inlet hole 710, and the liquid medicine enters the interior of the pipe fitting 79. Moreover, the blocking rod 78 is inserted into the blocking hole 711, and the liquid medicine cannot be discharged from the blocking hole 711. When the cam 9 continues to rotate and its protruding end faces upward, under the elastic force of the spring 713, the lifting rod 75 moves upward, the small frame 76 moves upward accordingly, and the pressing plate 77 blocks the inlet hole 710. At this time, the liquid medicine enters the interior of the empty groove 73 from the blocking hole 711 and is discharged from the discharge groove 74.

[0055] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be considered to be within the scope described in this specification.
