Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a wound and stoma infection prevention and care device. Background Technology

[0002] An ostomy, caused by a disease of the digestive or urinary system, requires surgical treatment to separate the intestinal tract and bring one end of the intestinal tract to the body surface (the anus or urethra is moved to the abdominal wall) to form an opening. Currently, cleaning the stoma often requires the use of a cleaning device. With existing cleaning devices, medical staff directly apply saline solution to the stoma surface. Because the saline solution easily flows onto the cleaning equipment and bed surface during cleaning, it requires subsequent handling by medical staff, causing inconvenience.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN217286691U discloses a cleaning device for wound and stoma care, comprising an adhesive fabric; a cleaning cover is provided at the top surface of the adhesive fabric, and a spray shell is provided at the top inner surface of the cleaning cover; a mounting component is provided at the bottom of the cleaning cover at the top of the adhesive fabric, and a groove is provided on the surface of the mounting component at the corresponding position of the slider; a water passage chamber is provided inside the spray shell, and vertical through holes are provided at equal intervals at the top inner surface of the spray shell, and inclined through holes are provided at equal intervals on the inner side surface of the spray shell. This device covers the surface space of the patient's stoma with the cleaning cover, thereby preventing saline solution from flowing everywhere during the cleaning process, thus avoiding the trouble of subsequent treatment by medical staff, and improving cleaning efficiency.

[0004] The above-mentioned device has the following problems in actual use: When the device uses the adhesive layer of the adhesive cloth to fit tightly against the patient's skin, the fixing principle of the adhesive cloth relies on mechanical adhesion, which depends on stickiness or friction and cannot form a seal. It is easily loosened by skin movement and sweat, thus failing to provide a continuous and stable negative pressure, which means that the adhesive cloth has a certain risk of loosening. Summary of the Invention

[0005] This invention provides a wound and stoma infection prevention and care device to solve the problem that the adhesive fabric of existing care devices has a certain risk of loosening during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wound and stoma infection prevention and care device, comprising a receiving box with an open bottom, a care mechanism disposed within the receiving box, and a care box with open ends; the receiving box has an inlet; the care box is fixedly connected to the receiving box and communicates with the inlet; the care mechanism includes a care component and auxiliary components symmetrically arranged on both sides of the receiving box along the width direction; the care component includes an inner plate, a water plate, an inner hole on the inner plate, and several water holes on the water plate; the inner plate is fixedly connected to the inner wall of the care box; the water plate is connected to the inner hole; the auxiliary components include a piston cylinder, a piston block, a suction tube, a drain pipe, a drain hole on the receiving box, several suction holes on the suction tube, and a power unit for driving the piston block to reciprocate along the length direction of the piston cylinder; the piston cylinder is fixedly connected to the receiving box; the piston block is slidably connected to the piston cylinder; the suction tube communicates with the piston cylinder; the two ends of the drain pipe are respectively connected to the piston cylinder and the drain hole.

[0007] The principles and advantages of this scheme are: The opening of the container is placed against the patient's stoma skin, placing the stoma within the care box. Due to the gap between the care box and the container, a sealed cavity is formed between the patient's skin, the inner wall of the container, and the outer wall of the care box. During cavity formation, the interaction of the piston block and piston cylinder allows the suction tube to completely remove air from the cavity, which is then discharged outside the container through the drain tube and drain hole. Therefore, under the combined action of the piston block and piston cylinder, a pressure difference exists between the air pressure inside the cavity and the external atmospheric pressure, causing the external atmospheric pressure to tightly adhere the container and care box to the patient's skin surface, thus achieving a stable suction effect.

[0008] After the container and care box are attached to the patient's surface, saline solution is discharged through the water hole and acts on the patient's stoma to clean it, thereby effectively washing away foreign objects and bacteria at the stoma, reducing the risk of infection and promoting the healing of the patient's stoma.

[0009] Furthermore, it also includes auxiliary tubes symmetrically arranged on both sides of the container along its length; the auxiliary tubes have several auxiliary holes; both ends of the auxiliary tubes are connected to flexible tubes, which are connected to the suction tube; the auxiliary part also includes an auxiliary unit; the auxiliary unit includes an auxiliary block and a bottom block; the auxiliary block is fixedly connected to the piston block; the bottom block is fixedly connected to the auxiliary block, and both ends of the bottom block are fixedly connected to the two auxiliary tubes respectively.

[0010] The auxiliary tube is designed to expand the air intake range within the cavity, thereby accelerating air absorption and enhancing the effect of negative pressure formation within the cavity.

[0011] As the auxiliary tube moves synchronously with the auxiliary block, its effective range is expanded, allowing it to absorb air from the cavity at different locations, thus enhancing its effectiveness. Therefore, through the static absorption of air by the suction tube and the dynamic absorption of air by the auxiliary tube, the efficiency and quality of cavity formation are further improved.

[0012] Furthermore, it also includes a nursing section installed in the nursing box; the nursing section includes a rectangular hollow plate, a sponge block, a slide groove opened on the nursing box, and a power unit for driving the rectangular hollow plate to reciprocate along the length of the slide groove; the rectangular hollow plate is slidably connected to the slide groove; the sponge block is fixedly connected to the rectangular hollow plate.

[0013] The sponge block can wrap around the stoma, preventing the care box from coming into contact with the stoma and thus reducing the risk of damage. At the same time, the sponge block can absorb flowing saline solution, reducing the amount of saline solution that seeps into the cavity and prolonging the cavity formation time.

[0014] The design of the sponge block to vibrate is intended to prevent saline solution from concentrating in a localized area of ​​the sponge block and to accelerate the overall penetration of saline solution into the sponge block, thereby enabling the sponge block to absorb saline solution more efficiently and fully.

[0015] Furthermore, the nursing component also includes a linkage unit; the linkage unit includes an annular hollow block and a motion unit for driving the annular hollow block to rotate; the annular hollow block is rotatably connected to the inner hole, and the water plate is fixedly connected to the annular hollow block.

[0016] During the rotation of the annular hollow block, the water plate rotates synchronously. The rotation of the water holes allows for spraying from different locations, thus expanding the drainage range of the saline solution and ensuring more thorough and complete contact between the saline solution and the stoma, thereby enhancing the effectiveness of the saline solution.

[0017] Furthermore, the linkage also includes several linkage pipes; the linkage pipes are hinged to the water plate and communicate with the water holes; several linkage rods are fixed to the inner wall of the nursing box; the linkage rods are located on the movement trajectory of the linkage pipes.

[0018] The linkage tube is designed to oscillate relative to the water inlet during its circumferential movement. This oscillation, in conjunction with the linkage rod, allows the tube to swing relative to the inlet. This oscillation diversifies the locations from which saline solution is discharged, ensuring comprehensive and efficient contact between the saline solution and the stoma, thus expanding its effective range and enhancing its therapeutic effect.

[0019] Furthermore, the water plate has several sets of sub-holes; each set of sub-holes consists of several sub-holes.

[0020] The design of the perforations is to change the pressure of the saline solution discharged from the water plate, thereby allowing for different pressures when the saline solution is discharged. This enables diversified cleaning of the patient's stoma, thus further enhancing the cleaning effect on the stoma.

[0021] Furthermore, the linkage also includes a cleaning unit; the cleaning unit includes a cleaning rod and a cleaning brush; the cleaning rod is fixedly connected to the inner wall of the care box; one end of the cleaning brush is fixedly connected to the cleaning rod, and the other end of the cleaning brush abuts against the water plate.

[0022] During the rotation of the water plate, the saline solution rotates synchronously. Under the action of the cleaning rod, the saline solution is mixed more thoroughly and comprehensively, so that the salt can be completely dissolved, avoiding local concentrations that are too high or too low, thus improving the uniformity of the saline solution.

[0023] The cleaning brush is designed to remove salt residue from the orifices and water holes, thereby reducing the probability of blockage and allowing saline solution to flow efficiently and fully through them, thus enhancing the saline solution drainage effect.

[0024] Furthermore, the power unit includes a power shaft, a cam, a recess, a first spring, and a power component for driving the power shaft to rotate; the power shaft is rotatably connected to the housing; the cam is fixedly connected to the power shaft and abuts against the piston block; the recess is fixedly connected to the housing; the piston block and the recess are slidably connected; and the two ends of the first spring are respectively connected to the piston block and the recess.

[0025] During the rotation of the drive shaft, the cam rotates synchronously. During cam rotation, when the cam's protrusion abuts against the piston block, the piston block moves vertically downwards, compressing the first spring; when the piston block's protrusion no longer abuts against the piston block, the piston block returns to its original position under the action of the first spring, and the piston block moves vertically upwards. Therefore, the piston block can perform vertical reciprocating motion.

[0026] Furthermore, the motion unit includes an inner shaft, a gear, and a ring rack; the inner shaft is rotatably connected to the nursing box and fixedly connected to the power shaft; the gear is fixedly connected to the inner shaft; the ring rack is fixedly connected to the ring hollow block and meshes with the gear.

[0027] During the rotation of the power shaft, the inner shaft rotates synchronously. During the rotation of the inner shaft, the gears rotate synchronously. During the rotation of the gears, the gears mesh with the ring rack, thus enabling the ring rack to perform circumferential motion.

[0028] Furthermore, the auxiliary unit also includes a wall block, a fixing block, and a wall hole on the nursing box; the auxiliary block is attached to the outer wall of the nursing box and can seal the wall hole; the wall block is fixedly connected to the auxiliary block and can make vertical reciprocating motion in the wall hole; the fixing block is fixedly connected to the rectangular hollow plate and is located on the movement trajectory of the wall block; the power unit is a second spring; the two ends of the second spring are respectively connected to the rectangular hollow plate and the slide groove.

[0029] During the piston block's movement, the auxiliary block rotates synchronously. During the auxiliary block's movement, the wall block moves synchronously. During the wall block's movement, under the combined action of the wall block and the second spring, the fixed block can drive the rectangular hollow plate to perform intermittent reciprocating vibration.

[0048] Specific implementation process: The opening of the receiving box 1 is placed against the patient's stoma skin, so that the stoma is located inside the nursing box 31. Due to the gap between the nursing box 31 and the receiving box 1, a sealed cavity is formed between the patient's skin, the inner wall of the receiving box 1, and the outer wall of the nursing box 31. During cavity formation, the motor 25 is started, and the output shaft of the motor 25 drives the power shaft 22 to rotate. During the rotation of the power shaft 22, the cam 23 rotates synchronously. During the rotation of the cam 23, when the protrusion of the cam 23 abuts against the piston block 7, the piston block 7 moves vertically downwards, compressing the first spring; when the protrusion of the piston block 7 no longer abuts against the piston block 7, the piston block 7 returns to its original position under the action of the first spring, and the piston block 7 moves vertically upwards. Therefore, the piston block 7 can perform vertical reciprocating motion.

[0049] Through the cooperation of piston block 7 and piston cylinder 6, suction tube 8 can completely suck out the air in the cavity, and finally discharge it outside the receiving box 1 through discharge tube 9 and discharge hole 10. Therefore, under the combined action of piston block 7 and piston cylinder 6, there is a pressure difference between the air pressure inside the cavity and the external atmospheric pressure, which causes the external atmospheric pressure to tightly adhere the receiving box 1 and nursing box 31 to the patient's skin surface, thereby achieving a stable adsorption effect.

[0050] After the container 1 and the nursing box 31 are attached to the patient's surface, the saline solution in the storage cavity will be discharged through the water hole 5 and act on the patient's stoma to clean it, thereby effectively washing away foreign objects and bacteria at the stoma, thus reducing the risk of infection and promoting the healing of the patient's stoma.

[0051] The auxiliary tube 11 is designed to expand the range of air intake within the cavity, thereby accelerating air absorption and enhancing the effect of negative pressure formation within the cavity.

[0052] During the synchronous movement of the auxiliary tube 11 with the auxiliary block 12, the effective range of the auxiliary tube 11 is expanded, enabling it to absorb air from the cavity at different positions, thus further enhancing its effectiveness. Therefore, through the static absorption of air by the suction tube 8 and the dynamic absorption of air by the auxiliary tube 11, the efficiency and quality of cavity formation are further improved.

[0053] The sponge block 15 can wrap around the stoma, thus preventing the nursing box 31 from coming into contact with the stoma and reducing the damage caused by the nursing box 31 to the stoma. At the same time, the sponge block 15 can also absorb the flowing saline, thereby reducing the amount of saline that seeps into the cavity and prolonging the cavity formation time.

[0054] During the movement of auxiliary block 12, wall block 29 moves synchronously. During the movement of wall block 29, under the combined action of wall block 29 and the second spring, fixed block 30 can drive rectangular hollow plate 14 to reciprocate intermittently.

[0055] The vibration of the sponge block 15 is designed to prevent saline solution from concentrating in a localized area of ​​the sponge block 15 and to accelerate the overall penetration of saline solution into the sponge block 15, thereby enabling the sponge block 15 to absorb saline solution more efficiently and fully.

[0056] During the rotation of the power shaft 22, the inner shaft 26 rotates synchronously. During the rotation of the inner shaft 26, the gear 27 rotates synchronously. During the rotation of the gear 27, since the gear 27 meshes with the ring rack 28, the ring rack 28 can perform circumferential motion. During the motion of the ring rack 28, the annular hollow block 16 rotates synchronously.

[0057] During the rotation of the annular hollow block 16, the water plate 4 rotates synchronously. The rotation of the water hole 5 allows it to spray from different locations, thereby expanding the range of saline drainage and enabling the saline to come into more thorough and complete contact with the stoma, thus enhancing the effectiveness of the saline.

[0058] The linkage tube 17 is designed to swing relative to the water hole 5 during its circumferential movement with the water hole 5, in conjunction with the linkage rod 18. This swinging motion of the linkage tube 17 diversifies the locations from which saline solution is discharged, ensuring comprehensive and efficient contact between the saline solution and the stoma, thus expanding the range of action and enhancing its effectiveness.

[0059] The purpose of the perforation 19 is to change the pressure of the saline solution discharged from the water plate 4, thereby allowing the saline solution to be discharged at different pressures, thus enabling diversified cleaning of the patient's stoma and further enhancing the cleaning effect of the stoma.

[0060] During the rotation of the water plate 4, the saline solution rotates synchronously. Under the action of the cleaning rod 20, the saline solution is mixed more thoroughly and comprehensively, so that the salt can be completely dissolved, avoiding local concentrations that are too high or too low, thus improving the uniformity of the saline solution.

[0061] The cleaning brush 21 is designed to remove salt residue from the orifice 19 and water hole 5, thereby reducing the probability of blockage in the orifice 19 and water hole 5. This allows the saline solution to flow efficiently and fully through the water hole 5 and orifice 19, thus enhancing the saline solution drainage effect.

[0062] In summary, by creating negative air pressure, the flow range of saline solution is restricted. This allows the saline solution to thoroughly and efficiently clean the stoma, thereby reducing the probability of stoma infection and improving the efficiency and quality of the saline solution's effect.
