[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a drainage fixing pad for thoracic surgery. Background Technique
[0002] In thoracic surgery, a drainage fixing pad is a commonly used medical device for fixing the drainage tube in the thoracic cavity. The role of the drainage tube is to drain the accumulated gas, liquid or blood in the thoracic cavity to promote wound healing and prevent infection.
[0003] However, there are some problems in the use of traditional drainage fixing pads. The existing drainage fixing pads for thoracic surgery adopt a bandage fixing method, and the bandage often has a fixed tightness, which is difficult to adapt to the changes in the patient's body during the postoperative recovery process. An overly tight bandage may cause compression on the patient's skin and affect blood circulation; an overly loose one cannot effectively fix the drainage tube. Based on the above problems, this application document proposes a drainage fixing pad for thoracic surgery to improve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a drainage fixing pad for thoracic surgery, which can adjust the tightness of the bandage according to the patient, reduce the pressure and friction on the patient's skin, and reduce the risk of skin damage and pain. Secondly, the appropriate bandage tightness and the use of splints can reduce the occurrence of complications such as drainage tube displacement and infection.

[0024] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.
[0025] As Figures 1 to 5 shown, a drainage fixation pad for thoracic surgery includes a drainage pad 10. A through hole is provided in the middle of the drainage pad 10. Grooves are provided on both sides inside the drainage pad 10. A bracket 11 is fixed inside the groove. A rotating rod 12 is rotatably connected inside the bracket 11, and the rotating rod 12 penetrates through both ends of the bracket 11 and extends into the groove. A rotating disc 13 is fixed at one end of the rotating rod 12 and outside the bracket 11. A ratchet 14 is fixed at the end of the rotating rod 12 away from the rotating disc 13. A moving rod 15 is slidably connected to one end of the bracket 11, and the moving rod 15 penetrates through one end of the bracket 11 and extends to the upper end of the ratchet 14. A pawl 16 is fixed at the upper end of the moving rod 15 and on the ratchet 14. A first spring 17 is provided at the end of the moving rod 15 away from the pawl 16, and the first spring 17 is located outside the moving rod 15, and the upper end of the moving rod 15 penetrates through the upper end of the drainage pad 10.
[0026] In the above implementation method, when it is necessary to tighten the bandage 18, by rotating the rotating disk 13 counterclockwise, the rotation of the rotating disk 13 drives the rotation of the rotating rod 12. When the rotating rod 12 rotates, it drives the rotation of the ratchet 14. At the same time, when the rotating rod 12 rotates, it can wind up the bandage 18, so as to adjust the tightness of the bandage 18. At the same time, the cooperation of the ratchet 14 and the pawl 16 prevents the ratchet 14 from rotating clockwise. When it is necessary to loosen the bandage 18, by pushing the moving rod 15 to move towards one end of the ratchet 14 (it should be noted that in the initial state, the first spring 17 pushes the moving rod 15 through elastic force to limit the positions of the ratchet 14 and the pawl 16). When the moving rod 15 moves, it squeezes the first spring 17. At the same time, the pawl 16 no longer limits the ratchet 14. At this time, the rotating rod 12 rotates to adjust the tightness of the bandage 18.
[0027] Further, one side of the two brackets 11 away from each other is fixedly connected by a bandage 18, and the material of the bandage 18 is an elastic material.
[0028] In the above implementation method, the elastic bandage 18 usually has better air permeability, avoiding eczema or other skin problems caused by dampness. Secondly, the elastic bandage 18 can be appropriately stretched according to the body shape of the patient.
[0029] Further, anti-slip patterns are provided on the outer side of the rotating disk 13, and the material of the anti-slip patterns is rubber material.
[0030] In the above implementation method, the rubber anti-slip patterns can provide additional gripping force when rotating the rotating disk 13, preventing slipping during the rotation process. The rubber material itself has a certain elasticity, which can provide a more comfortable hand-held feeling and reduce hand fatigue caused by operation.
[0031] As Figure 1 、 Figure 6 and Figure 7 shown, cavities are respectively opened on both sides of the through hole inside the drainage pad 10. Circular cavities are respectively opened on one side of the two cavities away from each other. A clamping plate 20 is slidably connected inside the cavity. Fixing rods 21 are respectively fixed at both ends of one side of the two clamping plates 20 away from each other. One side of the two fixing rods 21 penetrates through the cavity and extends into the circular cavity. A limiting plate 22 is fixed on the side of the two fixing rods 21 away from the clamping plate 20, and the limiting plate 22 is located inside the circular cavity. A second spring 23 is arranged inside the circular cavity and on the outer side of the fixing rod 21.
[0032] In the implementation of the above method, fixing rods 21 are fixed at both ends of the clamping plate 20. A second spring 23 is arranged on the outer side of the fixing rod 21, and the second spring 23 is located inside the circular cavity. In the initial state, the second spring 23 pushes the limiting plate 22 to move close to one end of the circular cavity away from the clamping plate 20, and at the same time drives the clamping plate 20 and the fixing rod 21 to move. Secondly, the drainage tube can move from the inside of the cavity of the drainage pad 10.
[0033] Furthermore, threaded rods 24 are threadedly connected to both sides of the through hole. Knobs 25 are fixed to the upper ends of the two threaded rods 24. The lower ends of the threaded rods 24 penetrate through the cavity and extend into the drainage pad 10, and cams 26 are fixed on the outer sides of the threaded rods 24 and inside the cavity.
[0034] In the implementation of the above method, by rotating the knob 25, the knob 25 drives the threaded rod 24 to rotate inside the drainage pad 10. At the same time, the cam 26 is fixed on the threaded rod 24. When the threaded rod 24 rotates, the cam 26 can push the clamping plate 20 to move towards one side of the cavity. The two clamping plates 20 can fix the drainage tube. Using the two clamping plates 20 can effectively fix the drainage tube and prevent the drainage tube from shifting due to actions such as the patient turning over or moving.
[0035] Furthermore, the lower end of the drainage pad 10 is made of a flexible material.
[0036] In the implementation of the above method, the flexible material can evenly disperse the pressure and reduce the problems of skin tenderness and redness caused by long-term fixation.
[0037] The working principle of the present utility model is as follows:
[0038] When it is necessary to tighten the bandage 18, by rotating the rotating disk 13 counterclockwise, the rotating disk 13 drives the rotating rod 12 to wind up the bandage 18. At the same time, the ratchet 14 and the pawl 16 cooperate with each other to prevent the rotating rod 12 from rotating in the opposite direction. When it is necessary to loosen the bandage 18, by pushing the moving rod 15 to squeeze the first spring 17 and at the same time drive the pawl 16 to move forward. When the pawl 16 no longer limits the ratchet 14, the tightness of the bandage 18 can be adjusted. By rotating the knob 25, the cam 26 can be rotated so that the clamping plate 20 can move. When the two clamping plates 20 move, they will fix the drainage tube.
[0039] The above are only the preferred implementation manners of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
