Description

Technical Field

[0001] The invention relates to the technical field of skin cleaning and dressing change, and in particular to an integrated dressing change device. Background Art

[0002] Medical skin surface dressing change is a delicate nursing operation that involves using aseptic techniques to remove the old wound dressing, thoroughly clean the wound area, remove secretions and necrotic tissue, apply appropriate medications (such as disinfectants or antibacterial ointments), and finally cover the wound with a new sterile dressing to protect the wound from external contamination. This process is designed to maintain a clean wound environment, prevent infection, promote wound healing, while monitoring the progress of wound recovery, ensuring patient comfort and reducing the risk of complications.

[0003] When treating wounds, especially chronic wounds, and changing dressings by yourself, it is challenging for non-professionals to ensure aseptic operation because necessary disinfectants such as iodine tincture and saline are difficult to obtain in the home environment. This also invisibly increases the risk of wound infection, and the dressing process is extremely inconvenient.

[0004] For some larger wounds, they need to be sutured by pulling a certain length of suture and then cutting it with a cutting scissors. The processing efficiency is poor, and when the suture is removed, one side of the suture needs to be lifted up by other tools and then cut, which is difficult to use. Summary of the invention

[0008] The suture collecting sleeve is located in the middle groove of the support roller and is rotatably connected to a connecting column in the middle of the support roller. A suture limiting assembly is installed inside the groove of the support roller to realize the extraction and cutting of the suture.

[0009] Preferably, the roller push rod includes rotating rollers located on both sides of the gripping handle, the inner sides of the rotating rollers are rotatably connected with traction links, the top ends of the traction links are respectively rotatably connected to the bottom ends of the liquid push rods, and the top ends of the liquid push rods are fixedly connected with sealing rubber pads for sealing.

[0010] Preferably, the pressing plate includes pressing and flipping plates located on both sides of the gripping handle, the inner bottom of the pressing and flipping plates are fixedly connected with arc-shaped tooth plates, the bottom of the arc-shaped tooth plates fits the curvature inside the gripping handle, and the arc-shaped tooth plates are meshingly connected with the rotating roller.

[0011] Preferably, the cleaning sleeve includes multiple absorbent cotton layers located outside the supporting roller, the inner absorbent cotton layer is a liquid drying layer, the two middle absorbent cotton layers are saline cleaning layers, and the outer absorbent cotton layer is an iodine disinfection layer, and the multiple absorbent cotton layers are separated and pasted by multiple adhesive films.

[0012] Preferably, the suture limiting assembly includes a support column located inside the groove of the support roller, the side of the support column is fixedly connected to a triangular support arc plate, the top of the triangular support arc plate is fixedly connected to a suture limiting sleeve, and the bottom end of the suture limiting sleeve is fixedly connected to an inclined cutting knife.

[0013] Preferably, an adjusting sleeve is slidably connected to the outside of the liquid delivery pipe on the left side, an upper supporting ring is fixedly connected to the outside of the adjusting sleeve, the bottom end of the upper supporting ring is connected to the top of the supporting connecting seat through an extrusion spring, a sealing rubber sleeve for sealing is fixedly connected to the inner lower part of the adjusting sleeve, a transmission notch is provided on the outside of the iodine tincture disinfection layer, and the outside of the adjusting sleeve passes through the inside of the transmission notch and fits onto the outside of the brine cleaning layer.

[0014] Preferably, the interior of the rotating roller is connected to the interior of the gripping handle via a reset torsion spring, so as to realize automatic reversal of the rotating roller after the rotating roller is squeezed out of force.

[0015] Preferably, the liquid storage chamber on the left side stores physiological saline, and the liquid storage chamber on the right side stores iodine tincture.

[0016] Preferably, a limiting rubber sleeve is fixedly connected to the inner side of the suture limiting sleeve to achieve extrusion limitation of the suture.

[0017] Preferably, a limiting arc plate is fixedly connected to the side of the inner groove of the support roller, and a cutting angle is formed between the inclined cutting knife and the limiting arc plate.

[0018] Working principle: When treating the patient's wound, press the right side pressing flip plate inward, reverse the arc-shaped tooth plate inward, mesh the arc-shaped tooth plate with the rotating roller, and rotate the rotating roller. The rotating roller generates an upward thrust on the traction connecting rod, thereby pushing the liquid push column upward, and the liquid stored in the liquid storage chamber also moves upward, so that it is gathered through the gathering sleeve and transported to the outside of the iodine disinfection layer through the liquid delivery pipe. The surface of the iodine disinfection layer is evenly distributed through the siphon of the cotton layer to disinfect the patient's wound, and the pressure on the pressing flip plate is released. After the pressure is applied, the reset torsion spring generates a rotational force in the opposite direction on the rotating roller, and the traction connecting rod generates a downward pulling force on the liquid push column, and the pressing flip plate is unfolded through the engagement of the rotating roller and the arc-shaped tooth plate. After the disinfection is completed, the adhesive film protrudes out of the reserved part, and the adhesive film is torn off to expose the saline cleaning layer. At this time, the left pressing flip plate is pressed down, and the liquid is squeezed upward by the liquid push column, so that the physiological saline is transmitted and distributed on the surface through the saline cleaning layer siphon. In some special cases, a single cleaning cannot completely guarantee the cleanliness of the patient's skin surface, and the saline cleaning layer is siphoned through the adhesive film again. The physiological layer is torn off, and the extrusion spring generates an upward thrust on the adjustment sleeve, which fits the outside of the saline cleaning layer. The left side pressing flip plate is pressed again to perform a secondary cleaning of the patient's wound. After the secondary cleaning ensures that the wound surface is clean, a certain amount of physiological saline will remain on the skin surface. At this time, the saline cleaning layer is torn off again to expose the liquid drying layer, and the physiological saline on the wound surface is directly wiped dry. The sutures wrapped around the outside of the suture collection sleeve are drawn out and pressed into the inside of the suture limiting sleeve from top to bottom to limit the inner side of the rubber sleeve from squeezing the sutures, exert a certain resistance on the sutures, pull the sutures, and adjust the direction. Downward, the suture collecting sleeve rotates accordingly, and when the length of the suture reaches a certain extent, the suture is wrapped around the lower side of the triangular supporting arc plate, and the suture is pulled upward, and the suture is cut through the interaction between the traction link and the inclined cutting knife. When the suture is removed, the suture is contacted by the pointed end of the triangular supporting arc plate, and the tip of the triangular supporting arc plate is inserted into the suture connection by flipping the holding handle, and the holding handle is flipped to a certain extent, and the suture slides on the outside of the inclined cutting knife, thereby cutting the suture and completing the beginning of suture removal.

[0019] The present invention provides an integrated dressing changing device, which has the following beneficial effects:

[0020] 1. The present invention adjusts the pressure of the pressing flip plate to rotate the rotating roller, and generates an upward thrust on the liquid push column through the traction connecting rod, so that iodine tincture and physiological saline are squeezed into the interior of the iodine tincture disinfection layer and the saline cleaning layer, and the patient's skin surface is disinfected and cleaned, and then wiped dry by the liquid drying layer, thereby improving the cleaning efficiency of the device on the patient's skin surface, and making it more convenient to disinfect and clean the patient's wound.

[0021] 2. The present invention draws out the suture from the suture collecting sleeve and presses the suture into the interior of the suture limiting sleeve. The inner limiting rubber sleeve fixes the suture to ensure the stability of the suture. When cutting the suture, the lower side of the suture is wrapped around the bottom of the triangular supporting arc plate and the suture is pulled upward to cut the suture, thereby improving the convenience of the device in cutting the suture.

[0022] 3. The present invention integrates skin surface disinfection, skin surface cleaning and wound suture into one device, so that a single device can meet the needs of multiple functions, and the use order of the device is the same as the order of wound cleaning, which is more convenient to use.

DETAILED DESCRIPTION

[0034] 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.

[0035] Example:

[0036] Please refer to the attached Figure 1 , Figure 6 and attached Figure 8 The embodiment of the present invention provides an integrated dressing changing device, including a gripping handle 1 for hand-holding, wherein both sides of the gripping handle 1 are provided with a liquid storage chamber 17, and the inside of the liquid storage chamber 17 is slidably connected with a liquid push column 19, and the inner sides of the gripping handle 1 are respectively connected to the bottom ends of the liquid push column 19 through roller push rods, and both sides of the gripping handle 1 are turned over with a pressing plate to enable the liquid push column 19 to push the liquid in the liquid storage chamber 17 to discharge, and the top end of the liquid storage chamber 17 is fixedly connected with a gathering sleeve 24 for gathering liquid, and the top end of the gathering sleeve 24 is fixedly connected with a liquid delivery pipe 5 for liquid transmission, and the roller push rod includes a roller push rod 24 located inside the gripping handle 1.

[0037] When treating the patient's wound, the operator needs to press the pressing and flipping plate 3 on the right side inward, and at the same time, reverse the arc-shaped tooth plate 25 inward to make it tightly mesh with the rotating roller 21. This action triggers the rotation of the rotating roller 21, and then applies an upward thrust to the traction link 20, so that the liquid push column 19 is pushed upward, pushing the liquid in the liquid storage chamber 17 to move upward, and the liquid is guided by the gathering sleeve 24 and evenly transported outward through the liquid delivery pipe 5, and through the siphon effect of the cotton layer, the patient's wound is evenly disinfected. After the operation is completed, the pressure on the pressing and flipping plate 3 is released. At this time, the reset torsion spring 28 will apply a rotational force in the opposite direction to the rotating roller 21, causing the traction link 20 to pull the liquid push column 19 downward. At the same time, the pressing and flipping plate 3 returns to its original position with the cooperation of the rotating roller 21 and the arc-shaped tooth plate 25. This series of actions ensures the accuracy and efficiency of wound treatment.

[0038] Please refer to the attached Figure 2 , Attachment Figure 3 and Figure 7 A cleaning seat is installed on the top of the gripping handle 1, and the cleaning seat includes a supporting connection seat 4 located at the top of the gripping handle 1, and a supporting roller 9 is fixedly connected to the inner side of the supporting connection seat 4. A cleaning sleeve is installed on the outside of the supporting roller 9 to realize convenient cleaning of the patient's skin surface. The cleaning sleeve includes a plurality of adsorbent cotton layers located on the outer side of the supporting roller 9, the inner adsorbent cotton layer is a liquid drying layer 11, the two middle adsorbent cotton layers are saline cleaning layers 10, and the outer adsorbent cotton layer is an iodine disinfection layer 7. The plurality of adsorbent cotton layers are separated and pasted by a plurality of adhesive films 8. An adjusting sleeve 22 is slidably connected to the outside of the left liquid delivery pipe 5, an upper supporting ring 27 is fixedly connected to the outside of the adjusting sleeve 22, the bottom end of the upper supporting ring 27 is connected to the top of the supporting connecting seat 4 through an extrusion spring 23, a sealing rubber sleeve 26 for sealing is fixedly connected to the inner lower part of the adjusting sleeve 22, a transmission slot 6 is provided on the outside of the iodine tincture disinfection layer 7, the outside of the adjusting sleeve 22 passes through the inside of the transmission slot 6 and fits on the outside of the saline cleaning layer 10, the left liquid storage chamber 17 stores physiological saline, and the right liquid storage chamber 17 stores iodine tincture.

[0039] Utilizing the siphon effect of the cotton layer, the disinfectant is evenly covered on the surface of the iodine disinfection layer 7, and the patient's wound is thoroughly disinfected. After the disinfection step is completed, the operator pushes the adhesive film 8 outwardly out of its reserved part and tears it off to expose a new saline cleaning layer 10. Then, the operator presses the pressing flip plate 3 on the left side, and applies pressure upward through the liquid push column 19 to cause the physiological saline to flow and be evenly distributed on the wound surface again in a siphon manner through the saline cleaning layer 10. In special circumstances, if one cleaning is not enough to ensure the thorough cleaning of the skin surface, the operator needs to tear off the adhesive film 8 again to expose the saline cleaning layer 10. At this time, the extrusion spring 23 applies an upward thrust to the adjustment sleeve 22 to make it closely fit the outside of the saline cleaning layer 10. The operator presses the pressing flip plate 3 on the left side again to perform secondary cleaning of the wound. After secondary cleaning, it is ensured that the wound surface is clean. At this time, there may be physiological saline residue on the skin surface. Therefore, the operator tears off the saline cleaning layer 10 again to expose the liquid drying layer 11, which is directly used to wipe the physiological saline on the wound surface to complete the drying process.

[0040] Please refer to the attached Figure 4 , Attachment Figure 5 and attached Fig.10 , the suture collecting sleeve 12, the suture collecting sleeve 12 is located in the middle groove of the support roller 9, and is rotatably connected to the connecting column in the middle of the support roller 9, a suture limiting assembly is installed inside the groove of the support roller 9 to realize the extraction and cutting of the suture, and the suture limiting assembly includes a support column 13 located inside the groove of the support roller 9, a triangular support arc plate 15 is fixedly connected to the side of the support column 13, a suture limiting sleeve 14 is fixedly connected to the top of the triangular support arc plate 15, and an inclined cutting knife 16 is fixedly connected to the bottom of the suture limiting sleeve 14, refer to the attached Fig. 9 The inner side of the suture limiting sleeve 14 is fixedly connected with a limiting rubber sleeve 29 to limit the extrusion of the suture, and the inner groove side of the support roller 9 is fixedly connected with a limiting arc plate 2, and a cutting angle is formed between the inclined cutting knife 16 and the limiting arc plate 2;

[0041] A portion of the suture wrapped around the outside of the suture collecting sleeve 12 is taken out, and the operator inserts it into the inner cavity of the suture limiting sleeve 14 from top to bottom. At this time, the inner side of the limiting rubber sleeve 29 applies pressure to the suture to provide necessary resistance for the suture. As the operator pulls the suture downward, the suture collecting sleeve 12 begins to rotate. When the suture is pulled to an appropriate length, it is passed around the bottom of the triangular supporting arc plate 15 and pulled upward. In this process, the interaction force between the traction link 20 and the inclined cutting knife 16 comes into play to accurately cut the suture. This operation step is cleverly designed to ensure the accuracy and efficiency of suture cutting. The suture is contacted with the pointed end of the triangular supporting arc plate 15, and the tip of the triangular supporting arc plate 15 is inserted into the suture connection by flipping the holding handle 1, and the holding handle 1 is flipped to a certain extent. The suture slides on the outside of the inclined cutting knife 16, thereby cutting the suture and completing the beginning of suture removal.
