Description

Technical Field

[0001] The present invention relates to the technical field of medical care, and in particular to a leg bandaging device for medical care. Background Art

[0002] In clinical practice, medical staff need to change dressings regularly for patients with wounds. Dressing change is a commonly used treatment method in clinical practice. Medical staff examine the patient's wound and change the dressing to promote wound healing and prevent complications. During the dressing change process, the patient can observe changes in the wound, clean and disinfect the purulent wound, remove secretions, foreign matter, and necrotic tissue from the wound, maintain unobstructed drainage, eliminate factors that are not conducive to healing, control local infection, promote the growth of granulation tissue, and accelerate wound healing. Dressing change for clean wounds is mainly to observe the growth of the wound granulation tissue and whether there is secondary infection, and choose medication, drainage or other treatments according to different situations. Some patients with leg injuries need regular dressing changes to make the wound heal more quickly. After the dressing change, the patient's wound usually needs to be bandaged. Assisted bandaging with a bandaging device can effectively reduce work intensity.

[0003] After searching, the Chinese invention patent, publication number: CN113303977B, named: A leg bandaging device for medical care, the invention can quickly wrap the patient's wound in multiple layers through the winding mechanism. The winding mechanism changes its position under the action of the telescopic rod, thereby wrapping the patient's wound over a large area. The entire process only requires the assistance of medical staff, which greatly reduces the workload while improving work efficiency.

[0004] However, in actual use, the above and similar technical solutions still have some problems:

[0005] 1. In existing bandaging solutions, the bandage moves on a closed loop structure to perform the bandaging operation. In actual use, the leg needs to be inserted into the closed loop to complete the bandaging. However, after the bandage is completed, it is difficult to smoothly pull the leg out of the closed loop due to the thickening of the leg and the limited diameter of the closed loop. In addition, during the removal process, if the closed loop accidentally collides with the leg wound, it is very easy to cause secondary tearing of the wound, affecting the wound healing and the patient's recovery process;

[0006] 2. The current technical solution uses a bed-type flat bandage method, which has limitations. On the one hand, the bed-type structure is bulky and inconvenient to carry outside, and cannot meet the patient's bandage needs in non-fixed places. On the other hand, when the patient's legs cannot bend, it is difficult to smoothly extend the legs into the closed loop for bandaging. This brings great trouble to patients, especially those with limited mobility or severe leg injuries.

[0007] 3. During the bandaging process, the existing scheme lacks effective auxiliary mechanisms. When the bandage is directly wrapped, the tension generated by the bandage wrapped in the same direction will directly act on the wound. This continuous tension can easily cause pulling on the wound, which will not only increase the patient's pain, but may also damage the tissue structure around the wound, interfere with the normal healing process of the wound, and delay the patient's recovery time. Summary of the Invention

[0048] On the basis of Example 2, a leg bandaging device for medical care is provided, wherein an application mechanism 7 is connected to the end plate 41, and the application mechanism 7 includes a storage box 72, wherein a pair of end plates 41 are connected to the storage box 72, and a pair of support plates 73 are slidably connected to the storage box 72, and the pair of support plates 73 extend into the inner side of the protective shell 1, and a pair of support plates 73 are provided with cotton strips 74, and a break 77 is provided on the guide plate 43 close to the side of the storage box 72, so as to ensure that the gear section 47 can pass through the pair of support plates 73, so as to facilitate wrapping the cotton strips 74 inside and make it fit the leg.

[0049] In the present invention, a guide block 78 is installed on the guide plate 43 at the fracture 77, and a partition 71 is fixed between a pair of end plates 41 located on one side of the storage box 72. The guide block 78 is slidably connected to the partition 71, and a sliding shaft 75 is installed on the partition 71. The storage box 72 is slidably connected to the sliding shaft 75, and the storage box 72 is movably connected to the partition 71, thereby facilitating the placement of the cotton strips 74.

[0050] In the present invention, a control component 76 is connected to the support plate 73, and the control component 76 includes a rack 761. The rack 761 is installed on the support plate 73, and a third motor 762 is installed on the storage box 72. A first gear 763 is installed on the output shaft of the third motor 762. The first gear 763 is engaged with the rack 761 to facilitate pushing the cotton strip 74 to contact the leg.

[0051] In the present invention, a fixing plate 768 is installed on the side where the two support plates 73 are close to each other, and the end of the support plate 73 close to the fixing plate 768 is rotatably connected to the pressing plate 767. The end of the cotton strip 74 is arranged between the fixing plate 768 and the pressing plate 767. A pull rod 766 is slidably connected to the support plate 73, and one end of the pull rod 766 is slidably connected to one side of the pressing plate 767. An electric push rod 765 is installed between the pair of support plates 73, and a control bar 764 is installed on the telescopic end of the electric push rod 765. The pull rod 766 is fixedly connected to the control bar 764, so as to facilitate the clamping and release of the cotton strip 74.

[0052] Working principle: When bandaging a wound, grasp the pair of handles 5 and rotate them to both sides, so that the pair of protective shells 1 rotate and open around the rotation axis 45, thereby driving the two pairs of end plates 41 to open and the pair of guide plates 43 to separate. Place the injured leg between the two pairs of end plates 41, plug the rotating bandage roll 46 into the mounting block 48, so that the free end of the bandage roll 46 extends out of the protective shell 1, grasp it with your hands, close the protective shell 1, close the two pairs of end plates 41, close the pair of guide plates 43, and close the pair of guide plates 43. The inner diameter of the C-shaped end of the protective shell 1 and the end plate 41 is smaller than the diameter of the guide plate 43, so that it is easy to put on the leg, so that the protective shell 1 and the end plate 41 can contact the leg wall, thereby supporting the protective shell 1 and preventing the guide plate 43 from contacting the leg when moving. When placed flat, the protective shell 1 and the end plate 41 can support the leg, and a pair of first motors 444 are started by the controller 2 and powered by the battery 3, thereby driving the two pairs of drive rods 42 to rotate through the pulley 442 and the belt 441. The gear groove 49 on the driving rod 42 drives the gear segment 47 to rotate. The gear segment 47 is in a quarter ring shape, so that the gear segment 47 contacts the two driving rods 42 each time, thereby ensuring that the driving gear segment 47 rotates in a circular manner, thereby driving the bandage roll 46 to rotate, so that the bandage is wrapped around the leg, and the second motor 445 is started to drive the screw rod 443 to rotate. The screw rod 443 drives the guide plate 43 to slide, thereby driving the pair of guide plates 43 and the gear segment 47 to move, thereby driving the bandage roll 46 to move. The rotating end of the bandage roll 46 is made of rubber material with a certain friction force, thereby preventing the bandage roll 46 from rotating freely, ensuring the tension when the bandage is wrapped, thereby facilitating the wrapping of the entire leg and making it firmly wrapped. After the bandage is completed, the protective shell 1 is opened, and the gear segment 47 moves to the side away from the storage box 72, thereby facilitating the opening of the pair of guide plates 43, thereby facilitating the cutting of the bandage and taking out the leg. The portable shell is used, which is easy to carry and operate, and can be operated without lifting the leg.

[0053] When bandaging, disinfectant can be injected into the storage box 62 in advance through the pointed mouth pot. The pointed mouth pot contacts the valve block 66, pushing the valve block 66 to open, thereby injecting the disinfectant into the storage box 62. Before bandaging, the storage box 62 is driven to move around the leg, and the water pump 63 is started. The water pump 63 sucks the disinfectant through the hose 64 and pumps it out through the nozzle 61, so that the disinfectant is sprayed on the leg, thereby disinfecting the wound and preventing infection.

[0054] Different medicines can be injected into the storage box 62 as needed. When changing the dressing, recovery medicine can be injected. Before bandaging, the storage box 72 is pulled outward, and the storage box 72 slides through the sliding shaft 75. After the storage box 72 is pulled out, it is rotated downward around the sliding shaft 75. At this time, the pair of support plates 73 are in the state of being stored in the storage box 72, so that the storage box 72 is convenient to be rotated outward. The electric push rod 765 is started to pull the control bar 764 to move, and the pull rod 766 is pushed toward the pressing piece 767 to push the pressing piece 767 outward. At this time, a new sterile cotton strip 74 can be placed between the pair of pressing pieces 767, and the electric push rod 765 is started again to extend it, so that the pressing piece 767 is pulled to rotate and reset by the pull rod 766, and the fixing piece 768 is used. The gear section 47 can pass through between the pair of support plates 73 to wrap the bandage around the leg and wrap the bandage 74. Under the action of the bandage 74, the wound is protected to avoid pulling the bandage on the wound and causing discomfort.

[0055] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
