Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an automated bandaging device for surgical care. Background Technology

[0002] Surgical nursing is a discipline that enables patients to recover as soon as possible through the observation, treatment, and medical instruments provided by nurses for surgical patients. In the treatment of patients, the relevant instruments and equipment used are necessary. In the current technology, when bandaging the wounds of the injured, the bandaging operation is done manually. The nurse treats the wounds with the appropriate medication and then holds the bandage to wrap the area to be bandaged. The operation is cumbersome, time-consuming, labor-intensive, and inefficient.

[0003] To improve the convenience of bandaging, invention application number 2020114500802 discloses an automated bandaging device for surgical care and its usage method. The automated bandaging device includes a box with a cover on top. A U-shaped handle is located on one end of the top side of the cover. Hollow cylinders are rotatably mounted on both sides of the box, with a first turntable and a second turntable rotatably mounted on the ends of the two cylinders that are close to each other. This device can process different medications and apply them to the bandage via spray, effectively improving bandaging efficiency. However, the hollow cylinders cannot position the affected limb, allowing it to move easily during bandaging, leading to poor disinfection and bandaging effects. Furthermore, the gauze cannot be taut during bandaging, resulting in loose bandages that easily fall off. Therefore, it is necessary to propose an automated bandaging device with a stable outer shell for surgical care. Summary of the Invention

[0004] The purpose of this invention is to provide an automated bandaging device for surgical care, in order to solve the problems of inaccurate disinfection and bandaging positions and insecure bandaging mentioned in the background art.

[0005] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0006] An automated bandaging device for surgical care includes a treatment box, a faucet, and a top cover. The faucet is installed at the bottom of the right side wall of the treatment box. The bottom of the treatment box's inner cavity is sloped, allowing liquid stored at the bottom of the treatment box to drain out through the faucet. The top cover is hinged to the top left of the treatment box and is transparent, allowing observation of the interior of the treatment box. The device also includes a positioning mechanism, a first external gear ring, a support rod, a disinfection mechanism, a bandaging mechanism, a first motor, and a first gear. Two positioning mechanisms are installed opposite each other on the left and right sides of the treatment box. The first external gear ring is rotatably mounted on the right inner wall of the treatment box via a support. The support rod is horizontally installed on the left side wall of the first external gear ring. The disinfection mechanism is installed on the right end of the upper surface of the treatment box. The bandaging mechanism is installed on the left end of the support rod, with the bottom ends of the bandaging mechanism corresponding to those of the disinfection mechanism. The first motor is installed at the top of the right side wall of the treatment box. The first gear is installed at the output end of the first motor and meshes with the first external gear ring.

[0007] The purpose is to clamp and position the affected limb to ensure that it does not shift and that the disinfection position is accurate. The positioning mechanism includes a sleeve, clamping plates, teeth, a dust cover, a second external toothed ring, a second motor, a second gear, and a steel belt. The sleeve is installed on the outer wall of the treatment box and is annular. There are at least three clamping plates, which are equidistantly inserted into the inner wall of the sleeve along the circumference. There are several teeth, which are equidistantly installed on the concave surface of the right side wall of the clamping plates from the inside to the outside. The dust cover is installed on the outer wall of the sleeve. The second external toothed ring is rotatably fitted onto the outer wall of the sleeve, and the inner cavity of the dust cover limits the movement of the second external toothed ring. The second motor is installed on the right side wall of the dust cover. The second gear is installed at the output end of the second motor and meshes with the second external toothed ring. When the motor drives the second gear to rotate clockwise or counterclockwise, the second external toothed ring can rotate clockwise or counterclockwise. The steel belt is installed on the left side wall of the second external toothed ring and meshes with the teeth.

[0008] As a further aspect of the present invention, an adhesive pad is bonded to the inner side of the clamping plate.

[0009] As a further aspect of the present invention: the steel strip is spirally distributed on the left side wall of the second outer toothed ring.

[0010] As a further aspect of the present invention: the purpose is to rinse and disinfect wounds. The disinfection mechanism includes a storage box, a water pump, an inlet pipe, and a nozzle. The storage box is fixedly connected to the right end of the upper surface of the treatment box and is used to store disinfectant. The water pump is installed on the upper surface of the treatment box and is located on the left side of the storage box. The two ends of the inlet pipe are respectively connected to the inlet of the water pump and the left side wall of the storage box. The nozzle is vertically installed in the middle of the upper surface of the treatment box, and the top of the nozzle is connected to the outlet of the water pump.

[0011] As a further aspect of the present invention: the purpose is to adjust the tension of the rotating shaft to make the gauze wrap more tightly during bandaging and prevent the gauze from falling off at the wound. The bandaging mechanism includes a box body, a rotating shaft, a friction disc, a pressure plate, a friction pad, a spring, a knob, a baffle, a gauze roll, and positioning bolts. The box body is fixedly connected to the left end of the support rod, and slide tracks are provided at the top of the left and right inner walls of the box body. The rotating shaft is installed at the center of the box body and can rotate around its own axis through bearings. The friction disc is installed at the right end of the outer wall of the rotating shaft. The pressure plate and the friction pad are respectively inserted into the upper and lower slide tracks of the box body. At both ends; a spring is placed between the friction disc and the pressure plate, pressing down the friction plate to contact the friction disc under the spring force; a knob is screwed to the center of the upper surface of the box, and the bottom end of the knob is connected to the top end of the pressure plate through a bearing. When the knob is rotated clockwise or counterclockwise, the knob drives the pressure plate to move up or down, adjusting the pressure of the pressure plate on the spring; a baffle is locked in the middle of the outer wall of the rotating shaft by a set screw; a gauze roll is sleeved on the outer wall of the rotating shaft, and the gauze roll is located on the left side of the baffle; a positioning bolt is screwed to the left end of the rotating shaft, and the gauze roll is clamped and positioned by the positioning bolt cooperating with the baffle.

[0012] As a further aspect of the present invention: the lower surface of the friction pad is curved, and the curvature is the same as that of the side wall of the friction disc.

[0013] As a further aspect of the present invention: the left side wall of the baffle is uniformly provided with conical protrusions.

[0014] Compared with the prior art, the beneficial effects of the embodiments of the present invention are:

[0015] 1. This invention uses a second motor to drive a second gear to rotate clockwise or counterclockwise, causing the second external gear ring to rotate counterclockwise or clockwise, thereby causing the curved surface of the steel belt to press the teeth outward or inward, and the clamp to move outward or inward. The clamp is used to hold the affected limb, which has the function of positioning the affected limb and ensures accurate disinfection and bandaging.

[0016] 2. This invention uses clockwise or counterclockwise rotation of the positioning bolt to cause the positioning bolt to move the pressure plate upward or downward, increasing or decreasing the distance between the pressure plate and the friction plate. The pressure plate compresses the spring, causing the spring force to compress the friction plate and the friction disc, providing adjustable tension for the rotation of the gauze roll on the rotating shaft. This allows for adjustment of the tightness of the gauze wrapping, resulting in a good wrapping effect. Attached Figure Description

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1

[0026] Please see Figure 1-5 As shown in the embodiment of the present invention, an automated bandaging device for surgical care includes a treatment box 1, a faucet 2, and a top cover 3. The bottom of the right side wall of the treatment box 1 is fixedly connected to the left end of the faucet 2. The bottom of the inner cavity of the treatment box 1 is inclined, allowing liquid in the treatment box 1 to be discharged from the faucet 2. The top cover 3 is installed on the top left end of the treatment box 1 via a hinge. The top cover 3 is transparent, allowing observation of the interior of the treatment box 1. Positioning mechanisms 4 are installed on both the left and right sides of the treatment box 1. A first external toothed ring 5, which can rotate, is installed on the right inner wall of the treatment box 1 via a support. A support rod 6 is installed laterally on the left side wall of the first external toothed ring 5. A disinfection mechanism 7 for disinfecting wounds is installed on the right side of the upper surface of the treatment box 1. A bandaging mechanism 8 is installed on the left end of the support rod 6. The disinfection mechanism 7 and the bandaging mechanism 8 correspond vertically to each other for bandaging the disinfected wound. A first motor 9 is installed at the top of the right side wall of the treatment box 1. A first gear 10, which meshes with the first external toothed ring 5, is installed at the output end of the first motor 9.

[0027] Furthermore, the positioning mechanism 4 includes a sleeve 41 fixedly connected to the outer wall of the treatment box 1. The sleeve 41 is annular, allowing the patient's affected limb to pass through the sleeve 41 and enter the treatment box 1. Several clamps 42 are equidistantly inserted into the outer wall of the sleeve 41 along the circumference, with at least three clamps 42. Rubber pads are adhered to the inner side of the clamps 42. The clamps 42 move inward to clamp and position the affected limb. The high elasticity of the rubber pads can prevent pressure sores from forming on the surface of the affected limb. Teeth 43 are installed equidistantly from the inside to the outside on the concave surface of the right side of the clamps 42. A dust cover 44 is installed on the outer wall of the sleeve 41, and a rotatable second external toothed ring is fitted onto the outer wall of the sleeve 41. 45. The dust cover 44 limits the second external gear ring 45. A second motor 46 is installed on the right side wall of the dust cover 44. A second gear 47 is installed at the output end of the second motor 46 and meshes with the second external gear ring 45. The second gear 47 can drive the second external gear ring 45 to rotate counterclockwise or clockwise by the second motor 46. A steel belt 48 is installed on the left side wall of the second external gear ring 45. The steel belt 48 is arranged in a spiral shape and meshes with the teeth 43. When the second external gear ring 45 drives the steel belt 48 to rotate clockwise or counterclockwise, the curved surface of the steel belt 48 can squeeze the teeth 43 inward or outward.

[0028] Furthermore, the disinfection mechanism 7 includes a storage box 71 and a water pump 72 installed on the right end of the upper surface of the treatment box 1. The water pump 72 is located on the left side of the storage box 71. The storage box 71 is used for storing disinfectant. The inlet of the water pump 72 is connected to the bottom left side of the storage box 71 through an inlet pipe 73. A nozzle 74 is installed at the center of the upper surface of the treatment box 1 along the vertical direction. The top of the nozzle 74 is connected to the outlet of the water pump 72. Under the sharp action of the water pump 72, the disinfectant in the storage box 71 is drawn out and delivered to the nozzle 74. The nozzle 74 sprays the disinfectant onto the wound of the affected limb to disinfect the wound.

[0029] Furthermore, the bandaging mechanism 8 includes a box 81 fixedly connected to the left end of the support rod 6. Slides are provided at the top of the left and right inner walls of the box 81. A rotating shaft 82, capable of rotating around its own axis, is mounted at the center of the box 81 via a bearing. A friction disc 83 is mounted on the right end of the outer wall of the rotating shaft 82. Pressure plates 84 and friction plates 85 are respectively inserted into the upper and lower ends of the slides of the box 81. A spring 86 is placed between the pressure plate 84 and the friction plate 85. Under the elastic force of the spring 86, the friction plate 85 is pressed down to contact the friction disc 83, providing tension for the rotation of the rotating shaft 82. The lower surface of the friction plate 85 is curved, and its curvature is the same as the side wall curvature of the friction disc 83. The friction plate 85 is in full contact with the friction disc 83, and the friction plate 85 provides tension to the friction disc 83. The resistance is stable. A knob 87 is screwed to the center of the upper surface of the box 81. The bottom end of the knob 87 is connected to the pressure plate 84 through a bearing. When the knob 87 rotates clockwise or counterclockwise, it can pull the pressure plate 84 to move up or down. A baffle 88 is locked in the middle of the outer wall of the rotating shaft 82 by a set screw. The position of the baffle 88 on the rotating shaft 82 can be changed by the set screw. A gauze roll 89 is sleeved on the outer wall of the rotating shaft 82. The position of the gauze roll 89 is restricted by the baffle 88. A positioning bolt 810 is screwed to the left end of the rotating shaft 82. The positioning bolt 810 cooperates with the baffle 88 to clamp and position the gauze roll 89. The left side wall of the baffle 88 is evenly provided with conical protrusions to increase the friction with the gauze roll 89 and realize the synchronous rotation of the gauze roll 89 and the rotating shaft 82.

[0030] Working principle

[0031] Step 1: The affected limb is inserted into the treatment box 1 through the sleeve 41 and observed through the top cover 3. The wound is positioned directly below the nozzle 74. The second motor 46 drives the second gear 47 to rotate the second external toothed ring 45 clockwise. The steel belt 48 presses the teeth 43 inward, thereby causing all the splints 42 to move inward simultaneously. The splints 42 clamp and position the affected limb.

[0032] Step 2: The water pump 72 draws out the disinfectant from the storage tank 71 under its own suction and delivers it to the nozzle 74. The nozzle 74 sprays the disinfectant onto the wound to rinse and disinfect it.

[0033] Step 3: The outer end of the gauze roll 89 is fixed to the wound. The first motor 9 drives the first gear 10 to rotate, which in turn causes the first external gear ring 5 to drive the support rod 6 to make a circular motion. The gauze roll gradually wraps around the wound. Under the traction of the gauze roll, the shaft drives the friction disc 83 to rotate. Due to the elasticity of the spring 86, the friction plate 85 is pressed down. The friction plate 85 and the friction disc 83 cooperate to provide tension to the gauze roll 89 and prevent the bandage from loosening.

[0034] Step 4: When it is necessary to adjust the tension of the gauze roll 89, rotate the positioning bolt 810 clockwise or counterclockwise to cause the positioning bolt 810 to move the pressure plate 84 up or down. The distance between the pressure plate 84 and the friction plate 85 will increase or decrease, and the pressure plate 84 will compress the spring 86 to a lesser or greater degree, thereby achieving the adjustment of the tension of the gauze roll 89.

[0035] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
