[0001] The present invention relates to the technical field of medical equipment, and in particular to a thoracic postoperative chest tube fixing device and a use method thereof. Background Art

[0002] A drainage tube is a medical device used for clinical surgical drainage. It guides the pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some are used for urinary catheterization, some are used for wounds, and are used in the chest cavity, brain cavity, gastrointestinal tract, bile duct, etc. The purpose of surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and affect wound healing.

[0003] After chest surgery, a chest drainage tube needs to be inserted into the patient. Most of the drainage tubes are fixed with tape. The tape sticks to the skin, especially in hot weather when the skin is prone to sweating. Since the area covered by the tape is not airtight, bacteria will breed, which may induce infection. In addition, if the patient accidentally pulls the drainage tube during activities, there is a risk that the tube will fall off due to the movement and pulling of the tube. Summary of the invention

The transmission gear (703) meshes with the transmission tooth plate (702).

[0014] Furthermore, for a thoracic postoperative thoracic duct fixing device, the method steps are as follows:

[0015] S1: When in use, pull the binding strap. During the tightening process of the binding strap, the hollow fixing block will be driven to descend. The hollow fixing block drives the mounting arc block to descend. The two mounting arc blocks drive the elastic fixing cable to descend. The elastic fixing cable will contact the drainage tube inserted into the body during the descending process and drive the drainage tube to closely adhere to the patient's skin. During the descending process of the hollow fixing block, the fixing rod will be driven to descend. The fixing rod drives the L-shaped plate to descend. The L-shaped plate drives the limit sliding plate to descend. The limit sliding plate drives the L-shaped connecting plate to descend. The descending of the hollow fixing block will drive the movable rod to move towards the binding strap. The movable rod drives the L-shaped reinforcing plate to move towards the binding strap. The L-shaped reinforcing plate drives the L-shaped connecting plate to move. The L-shaped connecting plate drives the limit strip bar to slide on the strip-shaped reinforcing bar. The two L-shaped connecting plates simultaneously drive the elastic fixing cable to move towards the binding strap. At this time, the elastic fixing cable will be tightened under the pulling of the L-shaped connecting plate to further reinforce the drainage tube;

[0016] S2: The part between the fixing part of the drainage tube and the part where it enters the cylinder is in a bent state. During the movement of the patient, the drainage tube will be pulled. The annular card slot on the drainage tube will drive the annular clamping plate to rise. When the annular clamping plate contacts the inner wall of the top of the cylinder, it will be stuck and stop moving. At this time, the movable spring undergoes a compression deformation to prevent the drainage tube from slipping out of the patient's chest cavity during the pulling of the drainage tube. When the pulling of the drainage tube stops, the annular clamping plate will reset under the elastic force of the movable spring. The annular clamping plate clamps the annular card slot and drives the drainage tube to descend and return to its original position;

[0017] S3: During the upward movement of the annular clamping plate, the annular clamping plate drives the U-shaped transmission plate to rise, the U-shaped transmission plate drives the transmission toothed plate to rise, and the transmission toothed plate drives the rotating shaft to rotate under the action of the transmission gear. The rotating shaft drives several suction fan blades to rotate, and the rotating shaft generates suction force to suck the outside air through the ventilation slot on the right side of the fixed box. When the air enters the ventilation slot, it will pass through the sterile filter plate, and the sterile filter plate disinfects the air to prevent germs and bacteria from entering the fixed box, thereby reducing the risk of infection. The air inhaled by the air box will pass through the Z-shaped air duct and the circular air duct and finally be discharged from the guiding air hood. The guiding air hood will discharge the air to the position where the drainage tube is inserted into the patient's body to dissipate heat from the patient's skin. Since most of the part where the patient's chest cavity is connected to the drainage tube is fixed by tape, accelerating the blowing and heat dissipation of this part can achieve the effect of cooling down.

[0018] The present invention has the following beneficial effects:

[0019] (1) For the thoracic postoperative thoracic cavity pipeline fixing device of the present invention, when in use, pull the binding strap. During the tightening process of the binding strap, it drives the hollow fixing block to descend, the hollow fixing block drives the mounting arc block to descend, the two mounting arc blocks drive the elastic fixing cable to descend, and the elastic fixing cable will contact the drainage tube inserted into the body during the descending process and drive the drainage tube to closely adhere to the patient's skin. During the descending process of the hollow fixing block, it drives the fixing rod to descend, the fixing rod drives the L-shaped plate to descend, the L-shaped plate drives the limit sliding plate to descend, the limit sliding plate drives the L-shaped connecting plate to descend. The descending of the hollow fixing block drives the movable rod to move towards the binding strap, the movable rod drives the L-shaped reinforcement plate to move towards the binding strap, the L-shaped reinforcement plate drives the L-shaped connecting plate to move, the L-shaped connecting plate drives the limit strip rod to slide on the strip reinforcement rod, and the two L-shaped connecting plates simultaneously drive the elastic fixing cable to move towards the binding strap. At this time, the elastic fixing cable will be tightened under the pulling of the L-shaped connecting plate to further reinforce the drainage tube and improve the fixing effect on the drainage tube;

[0020] (2) For the thoracic postoperative thoracic cavity pipeline fixing device of the present invention, the part between the fixed part of the drainage tube and the entrance of the cylinder is in a bent state. During the movement of the patient, the drainage tube will be pulled. The annular card slot on the drainage tube drives the annular clamping plate to rise. When the annular clamping plate touches the inner wall of the top of the cylinder, it will be stuck and stop moving. At this time, the movable spring undergoes compressive deformation to prevent the drainage tube from slipping out of the patient's thoracic cavity during the pulling process of the drainage tube, thereby avoiding the patient from suffering pain and the risk of infection. When the pulling of the drainage tube stops, the annular clamping plate resets under the elastic force of the movable spring, the annular clamping plate clamps the annular card slot and drives the drainage tube to descend and return to its original position;

[0021] (3) In a thoracic cavity pipeline fixing device of the present invention, during the ascending process of the annular clamping plate, the annular clamping plate drives the C-shaped transmission plate to ascend, the C-shaped transmission plate drives the transmission gear plate to ascend, the transmission gear plate drives the rotating shaft to rotate under the action of the transmission gear, the rotating shaft drives several suction fan blades to rotate, the rotating shaft generates suction force to suck the outside air through the ventilation slot on the right side of the fixed box, when the air enters the ventilation slot, it will pass through the sterile filter plate, and the sterile filter plate disinfects the air to avoid germs and bacteria from entering the fixed box, thereby reducing the risk of infection. The air inhaled by the air box will pass through the Z-shaped air duct and the circular air duct and finally be discharged from the guiding air hood. The guiding air hood will discharge the air to the position where the drainage tube is inserted into the patient, which has a heat dissipation effect on the patient's skin. Since most patients' thoracic cavities are fixed to the drainage tube by adhesive tapes, accelerating the blowing and heat dissipation of this part can play a cooling effect, avoiding the risk of bacteria breeding due to overheating and sweating at the connection position between the thoracic cavity and the drainage tube, and further reducing the risk of inducing infection.

[0022] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

The sides of the two limiting sliding plates 111 that are away from each other extend into the two limiting sliding grooves 112 and are slidably connected to the two limiting sliding grooves 112 respectively.

[0037] like Figure 3 As shown, two reinforcement mechanisms 2 are arranged in the fixed box 1, and the reinforcement mechanism 2 includes a strip reinforcement rod 201 fixedly installed in the fixed box 1, and a limiting strip rod 202 is slidably installed in the strip reinforcement rod 201, and the top of the limiting strip rod 202 extends to the outside of the strip reinforcement rod 201, and the limiting strip rod 202 passes through the L-shaped connecting plate 109 and is slidably connected to the L-shaped connecting plate 109, and an L-shaped reinforcement plate 203 is slidably sleeved on the strip reinforcement rod 201, and a movable rod 204 is hingedly installed on the back of the L-shaped reinforcement plate 203, and the top of the movable rod 204 is hinged to the hollow fixed block 102.

[0038] The descent of the hollow fixed block 102 will drive the movable rod 204 to move toward the direction close to the binding strap 302, and the movable rod 204 will drive the L-shaped reinforcement plate 203 to move toward the direction of the binding strap 302. The L-shaped reinforcement plate 203 will drive the L-shaped connecting plate 109 to move, and the L-shaped connecting plate 109 will drive the limiting strip rod 202 to slide on the strip reinforcement rod 201. The elastic fixing rope 106 will be tightened under the traction of the L-shaped connecting plate 109 to further reinforce the drainage tube 104, thereby improving the fixing effect of the drainage tube 104.

[0039] like Figure 1 and Figure 4 As shown, a binding mechanism 3 is provided on the fixed box 1, and the binding mechanism 3 includes a rubber pad 301 fixedly installed on the fixed box 1, a strap 302 is fixedly installed on the top of the rubber pad 301, the strap 302 passes through the fixed box 1 and the hollow fixed block 102 and is slidably connected with the fixed box 1 and the hollow fixed block 102, a lock 303 is fixedly installed on the left side of the rubber pad 301, and a plug 304 is fixedly installed on the right end of the strap 302, and the lock 303 is adapted to the plug 304.

[0040] Pull the binding belt 302 , and the binding belt 302 will drive the hollow fixing block 102 to descend during the tightening process, and the hollow fixing block 102 will drive the installation arc block 105 to descend, and the two installation arc blocks 105 will drive the elastic fixing rope 106 to descend.

[0041] like Figure 2 As shown, two ventilation mechanisms 4 are provided on the fixed box 1 . The ventilation mechanism 4 includes a ventilation slot 401 opened on the left side of the fixed box 1 . A sterile filter plate 402 is fixedly installed in the ventilation slot 401 .

[0042] When the air enters the ventilation slot 401, it passes through the sterile filter plate 402, which sterilizes the air to prevent germs and bacteria from entering the fixed box 1, thereby reducing the risk of infection.

[0043] like Figure 4 and Figure 6 As shown, a movable mechanism 5 is arranged on the fixed box 1, and the movable mechanism 5 includes a cylinder 501 fixedly installed in the fixed box 1, the drainage tube 104 passes through the fixed box 1 and the cylinder 501, an annular groove 502 is opened on the outer wall of the drainage tube 104, a plurality of arc guide plates 503 are fixedly installed in the cylinder 501, an annular clamping plate 504 is fixedly installed in the cylinder 501, the inner wall of the annular clamping plate 504 passes through the gap between the plurality of arc guide plates 503 and contacts with the drainage tube 104, the bottom of the annular clamping plate 504 contacts with the bottom inner wall of the annular groove 502, a movable spring 505 is fixedly installed on the bottom inner wall of the cylinder 501, and the top of the movable spring 505 is fixedly connected with the annular clamping plate 504.

[0044] When the annular clamping plate 504 contacts the top inner wall of the cylinder 501, it will get stuck and stop moving. At this time, the movable spring 505 will be compressed and deformed to prevent the drainage tube 104 from slipping out of the patient's chest cavity during the process of pulling the drainage tube 104, thereby avoiding the patient from suffering from pain and the risk of infection. When the drainage tube 104 stops pulling, the annular clamping plate 504 is reset under the elastic force of the movable spring 505, and the annular clamping plate 504 is stuck in the annular groove 502 and drives the drainage tube 104 to descend and return to its original position.

[0045] like Figure 7As shown in the figure, a drying mechanism 6 is arranged in the fixed box 1. The drying mechanism 6 includes a wind box 601 fixedly installed in the fixed box 1. A rotating shaft 602 is rotatably installed in the wind box 601. The right end of the rotating shaft 602 extends outside the wind box 601. A plurality of suction fan blades 603 are fixedly installed on the rotating shaft 602. Two Z-shaped air ducts 604 are fixedly installed on the left side of the wind box 601.

[0046] The air inhaled by the wind box 601 will pass through the Z-shaped air duct 604 and the circular air duct 605 and finally be discharged from the guide wind cover 606. The guide wind cover 606 will discharge the air to the position where the patient inserts the drainage tube 104 to dissipate heat from the patient's skin. Since most of the part where the patient's chest cavity is connected to the drainage tube 104 is fixed by tape, the effect of cooling can be achieved by accelerating the blowing and heat dissipation of this part, avoiding the risk of bacteria breeding due to overheating and sweating at the position where the chest cavity is connected to the drainage tube 104, and further reducing the risk of inducing infection.

[0047] As Figure 5 and Figure 7 As shown in the figure, a transmission mechanism 7 is arranged on the top of the annular clamping plate 504.

[0048] During the rising process of the annular clamping plate 504, the annular clamping plate 504 drives the U-shaped transmission plate 701 to rise. The U-shaped transmission plate 701 drives the transmission gear plate 702 to rise. The transmission gear plate 702 drives the rotating shaft 602 to rotate under the action of the transmission gear 703.

[0049] As Figure 1-8 shown, a thoracic postoperative thoracic cavity pipeline fixing device, the method steps are as follows:

[0050] S1: When in use, pull the strap 302. The strap 302 will drive the hollow fixed block 102 to descend during the tightening process. The hollow fixed block 102 will drive the installation arc block 105 to descend. The two installation arc blocks 105 will drive the elastic fixing rope 106 to descend. The elastic fixing rope 106 will contact the drainage tube 104 inserted into the body during the descent process and drive the drainage tube 104 to adhere to the patient's skin. During the descent process of the hollow fixed block 102, the fixing rod 107 will be driven down. The fixing rod 107 will drive the L-shaped plate 108 to descend. The L-shaped plate 108 will drive the limit sliding plate 111 to descend. The limit sliding plate 111 The L-shaped connecting plate 109 is driven to descend, and the hollow fixed block 102 is driven to descend, which will drive the movable rod 204 to move in the direction close to the binding belt 302. The movable rod 204 drives the L-shaped reinforcement plate 203 to move in the direction of the binding belt 302. The L-shaped reinforcement plate 203 drives the L-shaped connecting plate 109 to move. The L-shaped connecting plate 109 drives the limiting strip rod 202 to slide on the strip reinforcement rod 201. The two L-shaped connecting plates 109 simultaneously drive the elastic fixing rope 106 to move in the direction close to the binding belt 302. At this time, the elastic fixing rope 106 will be pulled tight by the L-shaped connecting plate 109 to further reinforce the drainage tube 104.

[0051] S2: The portion between the fixed part of the drainage tube 104 and the part where it enters the cylinder 501 is in a bent state. The drainage tube 104 will be pulled during the patient's activities. The annular groove 502 on the drainage tube 104 will drive the annular clamping plate 504 to rise. The annular clamping plate 504 will be stuck and stop moving when it contacts the top inner wall of the cylinder 501. At this time, the movable spring 505 is compressed and deformed to prevent the drainage tube 104 from slipping out of the patient's chest cavity during the process of pulling the drainage tube 104. When the drainage tube 104 stops being pulled, the annular clamping plate 504 is reset under the elastic force of the movable spring 505, and the annular clamping plate 504 is stuck in the annular groove 502 and drives the drainage tube 104 to descend and return to its original position.

[0052] S3: During the upward movement of the annular clamping plate 504, the annular clamping plate 504 drives the U-shaped drive plate 701 to rise. The U-shaped drive plate 701 drives the drive gear plate 702 to rise. Under the action of the drive gear 703, the drive gear plate 702 drives the rotating shaft 602 to rotate. The rotating shaft 602 drives a plurality of suction fan blades 603 to rotate. The rotating shaft 602 generates a suction force to suck the outside air through the ventilation slot 401 on the right side of the fixed box 1. When the air enters the ventilation slot 401, it will pass through the sterile filter plate 402. The sterile filter plate 402 disinfects the air to prevent germs and bacteria from entering the fixed box 1, thereby reducing the risk of infection. The air inhaled by the air box 601 will pass through the Z-shaped air duct 604 and the circular air duct 605 and finally be discharged from the guiding air hood 606. The guiding air hood 606 will discharge the air to the position where the drainage tube 104 is inserted into the patient, which has a heat dissipation effect on the patient's skin. Since most of the part where the patient's chest cavity is connected to the drainage tube 104 is fixed by tape, the cooling effect can be achieved by accelerating the blowing and heat dissipation of this part.

6. A method for using a postoperative chest tube fixing device for thoracic surgery, using the postoperative chest tube fixing device for thoracic surgery as claimed in claim 5, characterized in that: The method steps are as follows: S1: When in use, the binding strap (302) is pulled. During the tightening process, the binding strap (302) drives the hollow fixing block (102) to descend. The hollow fixing block (102) drives the installation arc block (105) to descend. The two installation arc blocks (105) drive the elastic fixing rope (106) to descend. During the descent process, the elastic fixing rope (106) contacts the drainage tube (104) inserted into the body and drives the drainage tube (104) to be closely attached to the patient's skin. During the descent process of the hollow fixing block (102), the fixing rod (107) is driven to descend. The fixing rod (107) drives the L-shaped plate (108) to descend. The L-shaped plate (108) drives the limit sliding plate (111) to descend. The limit sliding plate (111) drives the limit sliding plate (111) to descend. The movable L-shaped connecting plate (109) descends, and the hollow fixed block (102) descends, which drives the movable rod (204) to move in the direction close to the binding belt (302). The movable rod (204) drives the L-shaped reinforcement plate (203) to move in the direction of the binding belt (302). The L-shaped reinforcement plate (203) drives the L-shaped connecting plate (109) to move. The L-shaped connecting plate (109) drives the limiting strip rod (202) to slide on the strip reinforcement rod (201). The two L-shaped connecting plates (109) simultaneously drive the elastic fixing rope (106) to move in the direction close to the binding belt (302). At this time, the elastic fixing rope (106) is pulled tight by the L-shaped connecting plate (109) to further reinforce the drainage tube (104). S2: The portion between the fixed part of the drainage tube (104) and the part entering the cylinder (501) is in a bent state. When the patient moves, the drainage tube (104) is pulled, and the annular groove (502) on the drainage tube (104) drives the annular clamping plate (504) to rise. When the annular clamping plate (504) contacts the top inner wall of the cylinder (501), it is stuck and stops moving. At this time, the movable spring (505) is compressed and deformed to prevent the drainage tube (104) from slipping out of the patient's chest cavity during the process of pulling the drainage tube (104). When the drainage tube (104) stops being pulled, the annular clamping plate (504) is reset under the elastic force of the movable spring (505), and the annular clamping plate (504) is stuck in the annular groove (502) and drives the drainage tube (104) to descend and return to its original position; S3: During the upward movement of the annular clamping plate (504), the annular clamping plate (504) drives the C-shaped drive plate (701) to rise. The C-shaped drive plate (701) drives the drive gear plate (702) to rise. Under the action of the drive gear (703), the drive gear plate (702) drives the rotating shaft (602) to rotate. The rotating shaft (602) drives a plurality of suction fan blades (603) to rotate. The rotating shaft (602) generates a suction force to suck the outside air through the ventilation slot (401) on the right side of the fixed box (1). When the air enters the ventilation slot (401), it will pass through the sterile filter plate (402). The sterile filter plate (402) disinfects the air to prevent germs and bacteria from entering the fixed box (1), thereby reducing the risk of infection. The air inhaled by the air box (601) will pass through the Z-shaped air duct (604) and the circular air duct (605) and finally be discharged from the guiding air hood (606). The guiding air hood (606) will discharge the air to the position where the patient inserts the drainage tube (104) to dissipate heat from the patient's skin. Since most of the part where the patient's chest cavity is connected to the drainage tube (104) is fixed by tape, accelerating the blowing and heat dissipation of this part can achieve a cooling effect.
