Description

Technical Field

[0001] The present invention relates to the technical field of surgical nursing, and specifically to a dressing change and disinfection device for surgical nursing. Background Technique

[0002] Dressing change and disinfection devices for surgical nursing are an essential part of the medical field. They are mainly used for wound cleaning, disinfection, and dressing change operations to ensure the safety and hygiene of patients during surgical nursing. After a surgical operation, medical staff usually determine the disinfection and dressing change frequency of the surgical wound according to the healing condition of the wound and the doctor's advice. Under normal circumstances, the first dressing change for a sterile incision is carried out around 3 days, and the infected incision should be dressed every day. By disinfecting and dressing the wound surface, wound secretions, foreign bodies, and necrotic tissues can be effectively removed, bacterial growth can be reduced, and good conditions for healing can be created. During the disinfection and dressing change process, medical staff first need to gently remove the dressing on the wound surface with forceps. If the dressing adheres to the wound surface during the removal process, it needs to be moistened with normal saline first and then slowly separated to avoid damaging the newly formed tissues. Subsequently, disinfection work can be carried out on the wound surface, and during the disinfection process, the corresponding cleaning order needs to be selected according to the type of wound surface (for example, for a normal wound surface, it needs to be disinfected in a circular manner from the center of the wound surface outwards, while for an infected wound surface, it is disinfected from the periphery to the center to avoid the spread of bacteria). After disinfection, multiple layers of gauze are covered on the wound surface; During the nursing process, medical staff usually carry out corresponding disinfection and dressing change treatments according to the specific conditions of the surgical wound. Among them, the skin folds of obese patients are prone to accumulating sweat and dander, thus forming a humid environment, which increases the risk of bacterial growth. Therefore, when treating the surgical wounds of some obese patients, the wound surface is usually rinsed with normal saline, and after drying, medicinal powders (such as zinc oxide powder, antibacterial powder, etc.) are sprinkled on the wound surface to reduce the risk of infection and promote wound healing. However, in the actual nursing process, since the application of medicinal powder on the wound surface is mostly manually operated by medical staff, during the application process, it is easily affected by factors such as the surrounding environment, resulting in uneven distribution of the medicinal powder on the wound surface. In the wound surface area with more distributed medicinal powder, the air permeability decreases, affecting oxygen exchange, and in the sparse area, an effective antibacterial barrier cannot be formed, thus affecting the postoperative rehabilitation of patients. For this reason, we propose a dressing change and disinfection device for surgical nursing. Summary of the Invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figures 1-11 The present invention provides a technical solution: a dressing change and disinfection device for surgical nursing, the present invention makes corresponding improvements to the technical problems in the background technology, including two bracket parts 1, each bracket part 1 includes a fixed bracket 11 and a movable bracket 12 located inside the fixed bracket 11 and slidably connected to the inner wall thereof, combined with the attached Figure 1 and attachedFigure 2 As shown, a flexible plate frame 117 made of flexible skin-friendly materials such as rubber or silica gel is installed at the bottom of each fixed bracket 11. Due to its flexible skin-friendly characteristics, the flexible plate frame 117 can fit the patient's skin. Subsequently, medical staff can fix the flexible plate frame 117 in the area near the patient's wound (not in contact with the wound) through medical adhesive tapes. The end of the movable bracket 12 is located outside the fixed bracket 11, and the ends of the two movable brackets 12 are connected by a telescopic unit 2. The telescopic unit 2 includes an aluminum frame 21 and an aluminum rod 22 with one end located inside the aluminum frame 21 and slidably connected to its inner wall. Thus, the position of the bracket part 1 can be changed through the aluminum frame 21 and the aluminum rod 22 to adapt to wound surfaces of different sizes. A sliding frame 3 is arranged on the telescopic unit 2. The initial position of the sliding frame 3 can be on the aluminum frame or the aluminum rod 22. In the initial state, the sliding frame 3 is fixed to the telescopic unit 2 by bolts. Refer to the attached Figure 5 and the attached Figure 6 As shown, a roller part 118 is installed on the sliding frame 3. Through the roller part 118, the sliding frame 3 can be limited to slide on the aluminum frame 21 and the aluminum rod 22. Further explanation, the roller part 118 is composed of a roller body, a slider rotatably connected to the roller body, and a spring. When the roller body is limited to slide on the aluminum frame 21, the spring is in a compressed state. When the roller body slides onto the aluminum rod 22, the spring resets so that the roller body contacts the aluminum rod 22, thereby ensuring the stable sliding of the sliding frame 3 on the aluminum frame 21 and the aluminum rod 22. A connecting frame 4 is also fixedly installed on the sliding frame 3. A connecting shaft body 41 rotatably connected to its inner wall is installed inside the connecting frame 4. Both ends of the connecting shaft body 41 are located outside the connecting frame 4, and a roller one 42 and a roller two 43 are installed in parallel on the connecting shaft body 41. Refer to the attached Figure 6 As shown, the radius of the roller two 43 is greater than that of the roller one 42, and the roller one 42 contacts the bottom of the aluminum frame 21, and the roller two 43 contacts the bottom of the aluminum rod 22. A mounting frame 5 is also connected to the connecting frame 4. A material bin 51 is arranged inside the mounting frame 5. A silica gel discharge port 52 is installed at the discharge end of the mounting frame 5. A sealing plate frame 53 is arranged in the material bin 51, and the sealing plate frame 53 is connected to the connecting shaft body 41 through a transmission unit 6. An aluminum ring 59 for placing a water pipe is fixedly installed on one side of the mounting frame 5, and a reel 50 for placing gauze is installed on the other side of the mounting frame 5.

[0019] Refer to the attached Figure 1 and the attached Figure 2As shown, during the process of applying medicine to the wound surface of a patient, medical staff can fix the flexible plate frame 117 near the patient's wound through a medical adhesive tape, that is, the wound is located between the two fixed brackets 11. Subsequently, when the sliding frame 3 moves on the aluminum frame and the aluminum rod 22, the connecting frame 4 can drive the additional frame 5 to move synchronously. During the movement of the additional frame 5, the sealing plate frame 53 inside it is opened under the action of the transmission unit 6, so that the medicine powder in the material bin 51 enters the silicone discharge port 52 from the discharge end of the additional frame 5 and flows out along the silicone discharge port 52 to be sprinkled on the patient's wound surface.

[0020] Combined with the attached Figure 3 and the attached Figure 4As shown, during actual use, the surgical wounds of patients vary, and thus the distances between the silicone discharge port 52 and the wounds also differ. If the silicone discharge port 52 is relatively close to the wound, it is likely to result in excessive medicated powder scattered on the wound. If the distance is relatively far, the scattered medicated powder is likely to be affected by surrounding environmental factors. Therefore, the present invention makes the following design: A reset spring 13 is also connected between the bottoms of the movable support 12 and the fixed support 11. One side of the movable support 12 is also provided with a scale groove. Through the scale groove, the overall height of the support part 1 formed by the movable support 12 and the fixed support 11 can be known. A plurality of clamping plate frames 121 are fixedly installed on the movable support 12. One side of each clamping plate frame 121 is an inclined surface and the other side is a right-angle surface. The plurality of clamping plate frames 121 are located inside the fixed support 11. A clamping roller part 111 slidably connected to the fixed support 11 is also installed inside the fixed support 11, and the clamping roller part 111 is located on the movement track of the clamping plate frame 121. A constant force spring 112 is connected between the clamping roller part 111 and the inner wall of the fixed support 11. A driving shaft body 113 slidably connected to the inner wall of the fixed support 11 is fixedly installed on one side of the clamping roller part 111, and a chuck 114 rotatably connected to the driving shaft body 113 is installed at the end of the driving shaft body 113. A fixed shaft body 115 is fixedly installed on the chuck 114. A clamping hole 116 is provided on the outer wall of the fixed support 11, and the fixed shaft body 115 is located inside the clamping hole 116. Then, when medical staff use it, they can pull up the movable support 12. During the process of pulling up the movable support 12, the clamping plate frames 121 on the movable support 12 will move synchronously with it, that is, the inclined surface of the clamping plate frame 121 will contact the clamping roller part 111 and exert a force on it, so that the clamping roller part 111 is subjected to the force to squeeze the constant force spring 112, and the driving shaft body 113 drives the chuck 114 to move in a specific direction. During the process of pulling up the movable support 12, the reset spring 13 is in a stretched state. Therefore, the movable support 12 has a tendency to move downward, but the right-angle surface of the clamping plate frame 121 contacts the clamping roller part 111, that is, the clamping roller part 111 hinders the downward movement of the clamping plate frame 121. When it is necessary to reset the movable support 12, the chuck 114 can be pulled, so that the fixed shaft body 115 on the chuck 114 leaves the clamping hole 116. During the process of pulling the chuck 114, the driving shaft body 113 moves synchronously with the chuck 114 and drives the clamping roller part 111 to leave the movement track of the clamping plate frame 121. In order to facilitate the medical staff to reset the two movable supports 12, the medical staff can rotate the chuck 114 when pulling the chuck 114, so that the clamping shaft body 69 will not enter the clamping hole 116 during the reverse movement, and thus the clamping roller part 111 will not be located on the movement track of the clamping plate frame 121. Then, the movable support 12 performs a reset movement under the action of the reset spring 13.

[0021] Combined with the attached Figures 7-11As shown in the figure, as a further limitation in the present invention, the transmission unit 6 includes a circular disc frame 61 fixedly installed on the rotating shaft body 54, and a fixed frame body 62 is fixedly installed on each circular disc frame 61. One end of the fixed frame body 62 is provided with a force application rod frame 63, and the force application rod frame 63 is rotatably connected to the end of the fixed frame body 62 through a pin shaft 64. A first torsion spring 65 is connected between the pin shaft 64 and the fixed frame body 62. A force receiving disc frame 66 is arranged below the circular disc frame 61, and a force receiving rod frame 67 is fixedly installed on the force receiving disc frame 66. The force receiving rod frame 67 is located on the movement track of the force application rod frame 63. A rotating shaft body 54 is fixedly installed on the sealing plate frame 53. One end of the rotating shaft body 54 penetrates through the inner wall of the installation frame 5 and extends to the outside thereof, and an annular disc 55 is fixedly installed at the end of the rotating shaft body 54. A transmission shaft body 56 is fixedly installed on the annular disc 55. The force receiving disc frame 66 is limited and slides on the transmission shaft body 56. A limit disc frame 57 is fixedly installed on one side of the installation frame 5, and a card slot 571 is opened on the limit disc frame 57. A second torsion spring 58 is connected between the annular disc 55 and the limit disc frame 57. The card slot 571 is located on the movement track of the force receiving rod frame 67. A fixed sleeve 68 fixedly connected to the circular disc frame 61 is also arranged between each fixed frame body 62, and a clamping shaft body 69 slidably connected to its inner wall is installed inside the fixed sleeve 68. A plastic spring 60 is connected between the clamping shaft body 69 and the fixed sleeve 68. A through hole 631 is arranged on the force application rod frame 63, and the through hole 631 is located on the movement track of the clamping shaft body 69. It should be noted that the plastic spring 60 of the present invention is preferably a spring with a relatively low elastic coefficient to ensure that when the fixed sleeve 68 rotates with the circular disc frame 61, the clamping shaft body 69 overcomes the pulling force of the plastic spring 60 under the action of centrifugal force to enter the through hole 631.

[0022] Specifically, in the actual use process, medical staff perform disinfection and dressing change work on the patient's wound surface. During the dressing change process, medicinal powder is sprinkled on the patient's wound surface. Before the dressing change, the wound surface of the patient needs to be disinfected. When the wound surface is exposed to the field of vision, the medical staff will fix the flexible plate frame 117 near the patient's wound through a medical adhesive tape, that is, the wound is located between the two fixed brackets 11. Referring to Figure 1 and Figure 5 As shown, a medical absorbent cloth is pasted between the two flexible plate frames 117. Subsequently, the medical staff fixes the pipeline for outputting physiological saline on the aluminum ring 59, and pulls the sliding frame 3 to move it on the aluminum frame 21 and the aluminum rod 22. Referring to Figure 1As shown in the middle figure, during the movement of the sliding frame 3, physiological saline is sprayed from the pipeline on the aluminum ring 59 to wash the wound surface of the patient, that is, to carry out cleaning and disinfection work. The flowing physiological saline will be absorbed by the medical absorbent fabric between the two flexible plate frames 117. It should be noted that medical staff need to judge whether further disinfection work is required according to the actual situation of the patient's wound surface. After the physiological saline flushing is completed, the medical staff remove the installation frame 5 and add medicinal powder to the bin 51 in the installation frame 5. Before adding the medicinal powder, the sealing plate frame 53 is in a state of sealing the bin 51, and the force receiving disc frame 66 is moved into the annular limit disc frame 57, that is, the force receiving rod frame 67 is located in the card slot 571. At this time, the force receiving disc cannot rotate, and thus the sealing plate frame 53 cannot rotate, that is, the sealing plate frame 53 is in a sealed state. After the medicinal powder is added to the bin 51, the installation frame 5 is fixed on the connection frame 4. It is judged whether to wind gauze on the reel 50 according to the characteristics of the added medicinal powder. If the medicinal powder needs to be exposed to the environment after being sprinkled on the wound surface, the wound surface is not bandaged with gauze. If the wound surface needs to be bandaged after the medicinal powder is sprinkled, gauze can be wound on the reel 50. One end of the gauze is connected to the skin in the area near the patient's wound surface through medical adhesive tape. Then, during the movement of the sliding frame 3, the silicone discharge port 52 first sprinkles the medicinal powder on the patient's wound surface, and the wound surface will be bandaged with gauze in the area where the medicinal powder is sprinkled; During the treatment of the patient's wound surface, first judge whether to change the height of the moving bracket 12 according to the area where the patient's wound surface is located, that is, to change the distance between the silicone discharge port 52 and the wound surface. If it is necessary to pull up the moving bracket 12, the medical staff can directly pull the moving bracket 12. During the upward movement of the moving bracket 12, the inclined surface of the clamping plate frame 121 will contact the clamping roller part 111 to apply a force to the inclined surface of the clamping roller part 111. The clamping roller part 111 is subjected to the force to squeeze the constant force spring 112, and the driving shaft body 113 drives the chuck 114 to move in a fixed direction. After pulling up to the specified height, no upward pulling force is applied to the moving bracket 12, and the clamping roller part 111 returns to its original position under the action of the constant force spring 112. At this time, the moving bracket 12 has a tendency to move downward. When the clamping roller part 111 will block the right-angle surface of the clamping plate frame 121, the moving bracket 12 cannot move downward; When the moving bracket 12 needs to move downward, the chuck 114 can be pulled so that the fixed shaft body 115 on the chuck 114 leaves the clamping hole 116. During the pulling process of the chuck 114, the driving shaft body 113 moves synchronously with the chuck 114 and drives the clamping roller part 111 to leave the movement track of the clamping plate frame 121. Then, the right-angle surface of the clamping plate frame 121 is no longer blocked by the clamping roller part 111, so that the moving bracket 12 moves downward; After the position of the mobile support 12 is determined, the medical staff pulls the sliding frame 3 to move on the aluminum frame 21 and the aluminum rod 22. During the movement of the sliding frame 3, the first roller 42 and the second roller 43 will move synchronously with it. On the aluminum frame 21 and the aluminum rod 22, the first roller 42 and the second roller 43 will rotate. The first roller 42 and the second roller 43 will drive the connecting shaft body 41 to rotate synchronously. The connecting shaft body 41 will drive the circular disc frame 61 to rotate. During the rotation of the circular disc frame 61, the fixed frame body 62 on it will rotate synchronously, so that the force-applying rod frame 63 on the fixed frame body 62 will perform a circular motion. During the movement of the force-applying rod frame 63, it will apply a force to the force-receiving rod frame 67. During this process, since the fixed sleeve 68 is fixedly connected to the circular disc frame 61, the fixed sleeve 68 will rotate with the circular disc frame 61. During the rotation of the clamping shaft body 69 in the fixed sleeve 68, it will move into the through hole 631 under the action of centrifugal force, that is, finally enter the through hole 631. Since the clamping shaft body 69 is located in the through hole 631, when the force-applying rod frame 63 contacts the force-receiving rod frame 67 during rotation, the force-applying rod frame 63 cannot rotate, so that the force-receiving rod frame 67 is affected by the force to drive the force-receiving disc to rotate. During the rotation of the force-receiving disc, it will drive the annular disc 55 and the rotating shaft body 54 to rotate through the transmission shaft body 56, so that the sealing plate frame 53 is adjusted in angle in the silo 51, that is, the sealing plate frame 53 no longer obstructs the medicine powder in the silo 51. The medicine powder enters the silica gel discharge port 52 through the discharge end of the installation frame 5 to sprinkle the medicine powder on the wound surface of the patient. During this process, when the force-receiving rod frame 67 leaves the movement track of the force-applying rod frame 63, the annular disc 55 will perform a reset movement under the action of the second torsion spring 58. During the reset process, the force-receiving rod frame 67 will continue to rotate under the action of other force-applying rod frames 63, so that the sealing plate frame 53 performs repeated angle adjustments in the silo 51 but does not seal the medicine powder. The repeated angle adjustment of the sealing plate frame 53 in the silo 51 is beneficial to the movement of the medicine powder in the silo 51, avoiding situations such as "arch bridges" of the medicine powder and reducing the probability of blockage. When the sliding frame 3 stops moving, that is, the first roller 42 and the second roller 43 do not rotate, at this time, components such as the connecting shaft body 41 and the circular disc frame 61 will not rotate, so that the clamping shaft body 69 is no longer affected by centrifugal force, and under the action of the plastic spring 60, the clamping shaft body 69 leaves the through hole 631. At this time, the force-applying rod frame 63 can rotate under the action of the pin shaft 64, and the force-receiving rod frame 67 will perform a reverse movement through the annular disc 55 under the action of the second torsion spring 58, and contact the force-applying rod frame 63 during the movement to make the force-applying rod frame 63 rotate under the action of the pin shaft 64. It should be noted that the elastic coefficient of the second torsion spring 58 is greater than the elastic coefficient of the first torsion spring 65. During the reset process, the annular disc 55 will drive the sealing plate frame 53 to reset through the rotating shaft body 54,Thus, the sealing plate frame 53 seals the silo 51 to prevent the outflow of the medicinal powder. Furthermore, in the actual application process, when applying the medicinal powder to the wound surface, if medical staff find that some areas of the patient's wound surface are not cleaned properly or there are other conditions, they can stop applying the medicinal powder at any time. If it is necessary to increase the spraying amount of the medicinal powder in a certain area, the medical staff can directly rotate the force-receiving disc frame 66. Under the driving action of the above components, the sealing plate frame 53 is opened, that is, the medicinal powder flows out to cover the wound surface. Furthermore, through the structural design of the present invention, the operation of applying medicine to the patient's wound surface can be effectively carried out, the influence of environmental factors on the operation of applying medicine can be reduced, and at the same time, the medical staff can determine the spraying amount of the medicinal powder according to the actual situation of the patient's wound surface to improve the nursing quality.
