Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of drain devices, and in particular to a portable drain device for thoracic surgery. Background Art
[0002] Closed chest drainage, also known as thoracostomy or chest tube surgery, is a relatively simple surgical procedure, mainly used to treat various pleural effusions, fluid accumulation and pneumothorax. The surgical operation is to first give local anesthesia, then place a catheter between the ribs as a drainage tube, and connect it to a water-sealed drainage bottle filled with saline, which can both expel gas and collect fluid in the chest cavity, so that the lung function can be slowly restored.
[0003] Generally, it will take some time after surgery for the patient to get out of bed and move around. The patient can be helped by family members or rehabilitation physicians to walk around in the ward. Before walking, the patient can try to put his feet on the ground and stand beside the bed. For patients who cannot leave the bed, they are still encouraged to do light limb stretching exercises in bed with the assistance of a rehabilitation physician. However, it is important to note when moving around: special attention should be paid to the drainage tube and drainage bottle when getting out of bed. For example, the drainage bottle can only be carried by the patient himself, and cannot be carried by others to prevent the drainage tube from slipping due to dragging. When the patient is carrying the drainage bottle, the drainage bottle must be below the waist, and the drainage bottle cannot be tilted at a large angle to ensure that the lower end of the drainage tube is always below the liquid level.
[0004] For easy carrying, the drainage bottle is equipped with a hanging rope on each side, and the patient must hold both hanging ropes at the same time. However, when getting out of bed, it is inconvenient to carry the bottle by hand, and the patient is inexperienced, which may lead to common problems: accidentally lifting the drainage bottle, causing the liquid to flow back; accidentally hanging or dragging the drainage tube, causing the drainage tube to fall off; the drainage bottle is tilted at too large an angle, causing the lower end of the drainage tube to be out of the liquid surface. Therefore, the existing thoracic surgical drains need to be improved to address the above problems. Summary of the invention
[0005] In view of the defects in the prior art, the tilting range of the drainage bottle is reduced, the probability of the drainage tube being pulled out is reduced, and the safety is improved. The invention provides a portable drainage device for thoracic surgery; it comprises a drainage bottle, a first tube body, a second tube body, a bottle bracket and a leg fixing frame; the drainage bottle is provided with a bottle cap, the first tube body and the second tube body both extend into the drainage bottle after passing through the bottle cap, and the lower end of the first tube body extends to the bottom of the drainage bottle, and the second tube body extends to the middle of the drainage bottle; the drainage bottle is placed on the inner side of the bottle bracket; the leg fixing frame comprises a base, a telescopic block and a rod end joint bearing; an open longitudinal slide groove is provided on the top of the base, and the lower end of the telescopic block is inserted into the longitudinal slide groove, so that the base and the telescopic block form a sliding connection; a rod end joint bearing is respectively provided on the bottom of the base and the top of the telescopic block, and each rod end joint bearing is provided with a strap connected to the leg; all the straps are facing one side of the base; a horizontal rotating shaft is provided on the other outer side of the base, and the rotating shaft is fixedly connected to the outer side of the bottle bracket, and is respectively bound to the upper part of the calf and the lower part of the thigh through two straps, so that the bottle bracket is located on the outer side of the knee joint.
[0006] The beneficial effects of this device are as follows: the second tube body is used for adding saline solution and connecting to the atmosphere, while the first tube body is connected to the drainage tube inserted into the patient's body. If the patient needs to get out of bed and walk or exercise after surgery, the leg bracket is fixed to the outer side of the knee joint, and the bottle holder and the saline solution therein are relied on by gravity. Whenever the leg swings forward and backward, the base will rotate relative to the bottle holder, while the bottle holder remains vertical and does not rotate or the amplitude of rotation is greatly reduced, thereby reducing the shaking of the saline solution as much as possible and greatly reducing the probability of the lower end of the first tube body being exposed to the liquid surface. In addition, the drainage bottle no longer needs to be carried by hand and can be installed near the knee joint without affecting walking. It also solves the problem of the drainage bottle being too high.
[0007] Preferably, the rotating shaft is provided with a ball head, and the ball head is connected to the ball head groove on the outer side of the base, so that the bottle holder can rotate and swing relative to the base. The ball head can rotate and swing in the ball head groove to meet the relative movement between the bottle holder and the leg fixing frame.
[0008] Preferably, a plurality of telescopic rods are arranged between the bottle holder and the base, and all the telescopic rods are evenly distributed along the circumference of the rotating shaft. A tension spring is arranged inside the telescopic rod, and each time the telescopic rod is extended, the elastic force of the tension spring can cause the telescopic rod to generate tensile stress, which is used to limit the maximum swing amplitude of the bottle holder to the left or right side of the leg during walking, that is, to avoid the bottle holder colliding with the leg and affecting walking.
[0009] Preferably, a thrust bearing sleeved on the outside of the rotating shaft is provided on the side of the bottle holder, the seat of the thrust bearing is fixedly connected to the bottle holder, and the shaft of the thrust bearing is fixedly connected to one end of all telescopic rods. A fixed ring opposite to the shaft is provided on the side of the base, and the other ends of all telescopic rods are fixedly connected to the side of the fixed ring. The thrust bearing and the fixed ring ensure the rotation relationship between the bottle holder and the base, while not affecting the swing amplitude of the telescopic rod controlling the bottle holder in the left and right directions.
[0010] Preferably, both ends of each telescopic rod are provided with end connection seats for connection.
[0011] Preferably, the rotating shaft is provided with a limit ring for limiting the axial movement of the shaft piece, so as to meet the safety requirements of the thrust bearing and prevent the seat piece and the shaft piece from separating due to excessive distance.
[0012] Preferably, each rod end joint bearing is provided with two fixing rods, the two fixing rods of each rod end joint bearing are located in the same horizontal plane and are distributed in an "eight" shape, and a binding strap is provided at the end of each fixing rod.

DETAILED DESCRIPTION
[0021] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.
[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.
[0023] like Figure 1 As shown, the present embodiment provides a portable drainage device for thoracic surgery, including a drainage bottle 1, a first tube body 2, a second tube body 3, a bottle bracket 4 and a leg fixing frame 5. The drainage bottle 1 is provided with a bottle cap, the first tube body 2 and the second tube body 3 both extend into the drainage bottle 1 after passing through the bottle cap, and the lower end of the first tube body 2 extends to the bottom of the drainage bottle 1, and the second tube body 3 extends to the middle of the drainage bottle 1. The second tube body 3 in this embodiment is used for adding physiological saline and connecting to the atmosphere, while the first tube body 2 is connected to the drainage tube inserted into the patient's body. In order to reduce the shaking of physiological saline in the drainage bottle 1, four horizontal partitions 6 are provided inside the drainage bottle 1, and all the horizontal partitions 6 are longitudinally evenly spaced and distributed in the lower part of the drainage bottle 1; each horizontal partition 6 is provided with a flow hole 7, and the flow holes 7 of every two adjacent horizontal partitions 6 are staggered. The physiological saline shakes in the drainage bottle 1 and is restricted by the horizontal partition 6. The shaking of the physiological saline is blocked, and the blocking effect of multiple horizontal partitions 6 is better. The principle of the horizontal partition 6 blocking the physiological saline is as follows:
[0024] After the physiological saline solution sways and floats upward, it is blocked by the lowest horizontal partition 6, which prevents the physiological saline solution from floating upward. If the tilt angle is large and the lowest water level exceeds the flow hole 7 of the lowest horizontal partition 6, part of the physiological saline solution will flow from the flow hole 7 to the bottom of the upper horizontal partition 6. Similarly, the shaking of this part of the physiological saline solution will also be blocked by this horizontal partition 6, and it can only flow upward from the flow hole 7 of this horizontal partition 6. The flow holes 7 of the four horizontal partitions 6 are staggered, which extends the flow path and greatly reduces the probability of the lower end of the first tube 2 being exposed to the liquid surface, thereby ensuring the negative pressure state of the first tube 2 and not affecting the recovery of the lungs.
[0025] The specific structure of the leg fixing frame 5 in this embodiment is as follows:
[0026] like Figure 2 , Figure 4 As shown, the leg fixing frame 5 includes a base 8, a telescopic block 9 and a rod end joint bearing 10; an open longitudinal slide groove is provided on the top of the base 8, and the lower end of the telescopic block 9 is inserted into the longitudinal slide groove, so that the base 8 and the telescopic block 9 form a sliding connection. A rod end joint bearing 10 is provided below the base 8 and above the telescopic block 9, respectively, and each rod end joint bearing 10 is provided with a strap 14 connected to the leg; a screw 11 adapted to the through hole of the rod end joint bearing 10 is provided below the base 8, and each screw 11 is equipped with a nut 12. The screw 11 passes through the through hole of the rod end joint bearing 10, and then the nut 12 is tightened. In this embodiment, all the straps 14 are facing one side of the base 8. Specifically, each rod end joint bearing 10 is provided with two fixing rods 13, and the two fixing rods 13 of each rod end joint bearing 10 are located in the same horizontal plane and are distributed in an eight-shaped pattern, and a strap 14 is provided at the end of each fixing rod 13. The binding strap 14 is provided with a Japanese-shaped buckle 15 , and the tightness of the binding strap 14 can be quickly adjusted by the Japanese-shaped buckle 15 .
[0027] like Figure 2 , Figure 3 As shown, the drainage bottle 1 in this embodiment is placed on the inner side of the bottle holder 4, and a horizontal rotating shaft 16 is provided on the other outer side of the base 8. The rotating shaft 16 is fixedly connected to the outer side of the bottle holder 4, and is respectively tied to the upper part of the calf and the lower part of the thigh through two straps 14, so that the bottle holder 4 is located on the outer side of the knee joint. The rotating shaft 16 is not only required to rotate, but also needs to swing, so a ball head 17 is provided on the rotating shaft 16, and the ball head 17 is connected to the ball head groove 18 on the outer side of the base 8, so that the bottle holder 4 can rotate and swing relative to the base 8. The ball head 17 can rotate and swing in the ball head groove 18 to meet the relative movement between the bottle holder 4 and the leg fixing frame 5.
[0028] like Figure 3 , Figure 4As shown, the purpose of the swing is to prevent the drainage bottle 1 from swinging with the shaking of the thigh in the left and right directions, but at the same time, the drainage bottle 1 cannot collide with the legs and affect walking. Therefore, four telescopic rods 19 are provided between the bottle holder 4 and the base 8, and all the telescopic rods 19 are evenly distributed along the circumference of the rotating shaft 16. A tension spring is provided inside the telescopic rod 19. Whenever it is extended, the elastic force of the tension spring can cause the telescopic rod 19 to generate tensile stress, which is used to limit the maximum swing amplitude of the bottle holder 4 to the left or right side of the leg during walking, that is, to prevent the bottle holder 4 from colliding with the legs and affecting walking. Further, a thrust bearing 20 is provided on the side of the bottle holder 4 and is sleeved on the outside of the rotating shaft 16. The seat plate 21 of the thrust bearing 20 is fixedly connected to the bottle holder 4, and the shaft plate 22 of the thrust bearing 20 is fixedly connected to one end of all the telescopic rods 19. A fixed ring 23 opposite to the shaft plate 22 is provided on the side of the base 8, and the other ends of all the telescopic rods 19 are fixedly connected to the side of the fixed ring 23. The thrust bearing 20 and the fixed ring 23 ensure the rotation relationship between the bottle holder 4 and the base 8, while not affecting the swing amplitude of the bottle holder 4 in the left and right directions controlled by the telescopic rod 19. Both ends of each telescopic rod 19 are provided with an end connection seat 25 for connection. In addition, the rotating shaft 16 is provided with a limit ring 24 for limiting the axial movement of the shaft piece 22. The safety requirements of the thrust bearing 20 are met to prevent the seat piece 21 and the shaft piece 22 from being separated due to excessive distance.
[0029] In this embodiment, the two fixing rods 13 above the leg fixing frame 5 are clamped on the front and rear sides of the lower thigh, and then the thigh is tightened with the bandage 14. Similarly, the two fixing rods 13 on the side of the leg fixing frame 5 are clamped on the front and rear sides of the upper calf, and then the calf is tightened with the bandage 14. During walking, the knee joint is bent, and the telescopic block 9 telescopes and slides in the base 8. At the same time, the rod end joint bearing 10 of the telescopic block 9 and the rod end joint bearing 10 of the base 8 swing accordingly, which greatly reduces the walking resistance. At the same time, relying on the gravity of the bottle holder 4 and the saline solution therein, whenever the leg swings forward and backward, the base 8 will rotate relative to the bottle holder 4, and the bottle holder 4 remains vertical and does not rotate with it or the amplitude of rotation is greatly reduced, which reduces the shaking of the saline solution as much as possible and reduces the probability of the lower end of the first tube 2 being exposed to the liquid surface.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
