Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular is a device suitable for fixing and protecting a drainage tube after thoracic surgery. Background Art

[0002] Thoracic surgery is an important means of treating chest diseases. Leaving a drainage tube after surgery can effectively discharge accumulated air and fluid in the chest cavity, promote lung re-expansion and chest closure, and play a key role in the patient's recovery. The drainage tube is generally used in conjunction with a fixing device to ensure that the drainage tube remains in a stable and safe position after surgery, so as to effectively drain the fluid or gas in the chest cavity while reducing the risk of infection and other complications.

[0003] At present, the commonly used methods for fixing thoracic postoperative drainage tubes in clinical practice mainly include suture fixation, adhesive tape fixation and simple clip fixation, but the above fixation methods all have some disadvantages. For example, although suture fixation can provide a certain fixation strength, there is a risk of damaging the skin and increasing infection, and suture fixation is not convenient for adjusting the position of the drainage tube; and adhesive tape fixation is easily affected by factors such as patient sweating and skin oil, resulting in a decrease in the viscosity of the adhesive tape, thereby making the drainage tube fixation ineffective; and the simple clip fixation method lacks effective protection for the drainage tube, and it is difficult to stably fix drainage tubes of different diameters. Therefore, a device for fixing and protecting drainage tubes after thoracic surgery is proposed to solve the problems raised in the background technology. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a device for fixing and protecting drainage tubes after thoracic surgery, which has the advantage of being convenient for stably fixing drainage tubes of different diameters.

[0005] To achieve the above object, the present invention provides the following technical solution: a device for fixing and protecting drainage tubes after thoracic surgery, comprising a waist elastic belt, and also comprising: A support block, wherein the support block is adhered to the surface of the waist elastic band by Velcro; and a moving component is movably connected inside the support block, and a drainage tube body is placed inside the waist elastic band; Clamping assemblies, the number of which is six, and the clamping assemblies are movably connected in an annular manner at equal distances inside the support block; An early warning component, which is arranged on one side of the waist elastic belt; Wherein, the moving assembly comprises a square block, and six rectangular plates are arranged at equal distances in a ring at the bottom of the square block, and oblique grooves are provided on the surfaces of the upper and lower ends of the rectangular plates; The clamping assembly comprises a support plate, the upper and lower ends of the support plate are fixedly connected with round rods, and the side of the support plate close to the drainage tube body is movably connected with an arc gasket.

[0006] Preferably, pressing blocks are movably connected to the interiors of both sides of the square block. One side of each pressing block is fixedly connected to an elastic member, and the other side of each pressing block penetrates through the outer wall of the support block and extends to the outside of the support block.

[0007] Preferably, the pressing blocks are elastically connected to the square block through the elastic members, and tooth blocks are fixedly connected to both ends of each pressing block; A toothed plate adapted to the tooth blocks is fixedly connected to the interior of the waist elastic band, and the tooth blocks are engaged with the toothed plate in the initial state.

[0008] Preferably, circular grooves are formed in the middles of the square block and the support block. The diameter of the main body of the drainage tube is smaller than the diameter of the circular groove, and square grooves for limiting the pressing blocks in the vertical direction are formed in both sides of the support block.

[0009] Preferably, the round rod is movably clamped inside the rectangular plate. A rectangular groove adapted to the round rod is formed in the inner wall of the waist elastic band. When the rectangular plate moves downward, the round rod and the support plate are driven to linearly move toward the main body of the drainage tube through the inclined groove.

[0010] Preferably, the arc-shaped gasket is corrugated. The arc-shaped gasket is made of medical soft silicone material, and the arc-shaped gasket abuts against the outer wall of the main body of the drainage tube.

[0011] Preferably, a plastic T-shaped block is arranged on the side of the arc-shaped gasket away from the main body of the drainage tube. A T-shaped groove is formed in the inner wall of the round rod, and the T-shaped groove is used for limiting the arc-shaped gasket in the vertical direction.

[0012] Preferably, a gap is left between the top of the arc-shaped gasket and the top end of the inner wall of the T-shaped groove. A button is arranged at the top end of the inner cavity of one of the T-shaped grooves, and the arc-shaped gasket abuts against the button after moving upward.

[0013] Preferably, the support block is made of transparent medical plastic material. A male surface magic tape with hooked fibers is fixedly connected to the side of the support block away from the warning component, and a female surface magic tape with fluffy fibers is arranged on the surface of the waist elastic band.

[0014] Preferably, male and female surface magic tapes are respectively arranged on the inner and outer walls at both ends of the waist elastic band. The two ends of the waist elastic band are adhered together through the complementarity of the magic tapes and form an oval ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation among structures such as the support block, the moving component, and the clamping component, the present invention facilitates the stable fixation of drainage tubes with different diameters. The round rod is movably clamped inside the inclined groove, so that when the rectangular plate moves downward, the cooperation between the two can drive the support plate to move horizontally and linearly toward the drainage tube body, and then the support plate drives the arc gasket to clamp the drainage tube body. Subsequently, by adjusting the downward movement distance of the square block to drive the rectangular plate, the horizontal movement distance of the arc gasket is adjusted, thereby facilitating the clamping and fixation of drainage tubes with different diameters.

[0016] Through the cooperation among structures such as the clamping component, the button, and the warning component, the present invention prevents the drainage tube from being overly pulled. The drainage tube body is clamped by several arc gaskets, thereby increasing the friction and contact area between the two. When the drainage tube body is pulled, the arc gasket can be driven to move together. After the arc gasket moves, it presses the button, and then the warning component is triggered by the button to emit an alarm, and the patient is reminded by the alarm sound, thereby preventing the drainage tube body from being overly pulled and causing tube detachment, and improving the overall practicality of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 7 shown, the present invention provides a fixing and protecting device suitable for a thoracic drainage tube, including a waist elastic band 1, and further including: A support block 2, the support block 2 is adhered to the surface of the waist elastic band 1 through a magic tape; and a moving component 3 is movably connected inside the support block 2, and a drainage tube body 7 is placed inside the waist elastic band 1; A clamping component 4, the number of the clamping components 4 is six, and the clamping components 4 are annularly and equidistantly movably connected inside the support block 2; An early warning component 6, the early warning component 6 is arranged on one side of the waist elastic band 1; Among them, the moving component 3 includes a square block 31, six rectangular plates 32 are annularly and equidistantly arranged at the bottom of the square block 31, and inclined grooves 33 are formed on the upper and lower surfaces of the rectangular plates 32; The clamping component 4 includes a support plate 41, round rods 42 are fixedly connected to the upper and lower ends of the support plate 41, and an arc-shaped gasket 43 is movably connected to one side of the support plate 41 close to the drainage tube body 7.

[0021] Adopting the above solution: by movably clamping the round rod 42 inside the inclined groove 33, when the rectangular plate 32 moves downward, the cooperation between the two can drive the support plate 41 to move horizontally and linearly in the direction of the drainage tube body 7, and then drive the arc-shaped gasket 43 to clamp the drainage tube body 7 through the support plate 41. Subsequently, by adjusting the downward movement distance of the square block 31 to drive the rectangular plate 32, the horizontal movement distance of the arc-shaped gasket 43 can be adjusted, thereby facilitating the clamping and fixing of drainage tubes with different diameters.

[0022] As Figures 2 to 5 、 Figure 7 shown, pressing blocks 34 are movably connected to the inner sides of both sides of the square block 31, an elastic member 35 is fixedly connected to one side of the pressing block 34, the other side of the pressing block 34 penetrates through the outer wall of the support block 2 and extends to the outside of the support block 2, the pressing block 34 is elastically connected to the square block 31 through the elastic member 35, tooth blocks 36 are fixedly connected to both ends of the pressing block 34, and a tooth plate 37 matched with the tooth blocks 36 is fixedly connected inside the waist elastic band 1, and the tooth blocks 36 are clamped with the tooth plate 37 in the initial state.

[0023] Adopting the above solution: By pressing the pressing block 34 through the outer wall of the support block 2, its function is, specifically Figure 2 As can be seen, the surface of one end of the pressing block 34 passing through the support block 2 is flush with the outer wall of the support block 2. Therefore, by making the two flush, it can effectively prevent one end of the pressing block 34 from being accidentally touched and pressed. Subsequently, by pressing the pressing block 34 towards the inside of the support block 2 for a certain distance, the pressing block 34 can drive the toothed block 36 to disengage from the toothed plate 37, thus facilitating the adjustment of the position of the pressing block 34.

[0024] As Figure 3 , Figure 5 and Figure 6 shown, circular grooves are provided in the middle of both the square block 31 and the support block 2. The diameter of the drainage tube body 7 is smaller than the diameter of the circular groove. Square grooves for limiting the pressing block 34 in the vertical direction are provided on both sides of the support block 2. The round rod 42 is movably clamped inside the rectangular plate 32. A rectangular groove adapted to the round rod 42 is provided on the inner wall of the waist elastic band 1. When the rectangular plate 32 moves downward, the round rod 42 and the support plate 41 are driven to move linearly towards the drainage tube body 7 through the inclined groove 33. The arc-shaped gasket 43 is corrugated. The arc-shaped gasket 43 is made of medical soft silicone material. The arc-shaped gasket 43 abuts against the outer wall of the drainage tube body 7.

[0025] Adopting the above solution: Since the arc-shaped gasket 43 is corrugated, its function is that because there are corrugated textures on the surface of the arc-shaped gasket 43, when it contacts the drainage tube, these textures can increase the contact area and roughness, thereby generating greater friction, so that the drainage tube is firmly clamped between the gaskets and is not easy to slide or shift. Moreover, since the arc-shaped gasket 43 is corrugated, it can also evenly disperse the clamping force around the drainage tube body 7, avoiding excessive local pressure on the drainage tube body 7 and causing damage. Therefore, this uniform pressure distribution can not only better fix the drainage tube body 7, but also reduce the risk of deformation or blockage of the drainage tube body 7 caused by uneven pressure, ensuring the smoothness of the drainage tube body 7. As Figure 4 and Figure 6 shown, a plastic T-shaped block is provided on the side of the arc-shaped gasket 43 away from the drainage tube body 7. A T-shaped groove 44 is provided in the inner wall of the round rod 42. The T-shaped groove 44 is used to limit the arc-shaped gasket 43 in the vertical direction. There is a gap between the top of the arc-shaped gasket 43 and the top end of the inner wall of the T-shaped groove 44. A button 5 is provided at the top end of the inner cavity of one of the T-shaped grooves 44. The arc-shaped gasket 43 abuts against the button 5 after moving upward.

[0026] Adopt the above solution: Clamp the drainage tube body 7 by a plurality of arc-shaped gaskets 43, so as to increase the friction force and contact area between the two, and then when the drainage tube body 7 is pulled, it can drive the arc-shaped gasket 43 to move together. After the arc-shaped gasket 43 moves, it presses the button 5, so as to trigger the warning component 6 to send out an alarm through the button 5, and then remind the patient through the alarm sound, so as to prevent the drainage tube body 7 from being pulled excessively and causing tube detachment, and then improve the overall practicability of the device.

[0027] As Figure 1 shown, the support block 2 is made of transparent medical plastic material. A male surface magic tape with hooked fibers is fixedly connected to the side of the support block 2 away from the warning component 6. A female surface magic tape with fluffy fibers is arranged on the surface of the waist elastic band 1. The inner and outer walls of both ends of the waist elastic band 1 are respectively provided with male and female surface magic tapes. The two ends of the waist elastic band 1 are adhered together through the complementarity of the magic tapes and form an oval ring.

[0028] Adopt the above solution: Since the support block 2 is made of transparent medical plastic material, its function is that because the medical plastic material is relatively light, it will not bring too much burden to the patient, thus facilitating the patient to carry and move, and then being beneficial to improving the comfort and convenience of the patient. At the same time, the medical plastic also has good transparency. Therefore, it is convenient for medical staff to observe the clamping force on the drainage tube body 7, and then improve the convenience and practicability of the device; Since a magic tape is arranged on one side of the support block 2, it is convenient to paste the support block 2 onto the surface of the waist elastic band 1 according to needs through the male surface magic tape. The working principle and usage process of the present invention: First, the patient opens the connection part at both ends of the waist elastic band 1, wraps it around the waist, and fixes the waist elastic band 1 at the waist according to the patient's waist circumference through the complementarity of the magic tapes at both ends of the waist elastic band 1. Subsequently, the medical staff passes one end of the drainage tube body 7 through the circular groove in the middle of the support block 2, so that a part of the drainage tube body 7 is located inside the support block 2. Then, the medical staff presses the two pressing blocks 34 towards the inside of the support block 2, so that the two pressing blocks 34 move towards each other and drive the tooth blocks 36 at their two ends to move synchronously, and then the tooth blocks 36 are disengaged from the tooth plate 37 after moving; When the tooth block 36 is disengaged from the tooth plate 37, at this time, while holding down the pressing block 34, the medical staff pulls downward, so as to drive the square block 31 and several rectangular plates 32 fixed to its bottom to move downward together through the pressing block 34. While the rectangular plate 32 moves downward, the round rod 42 slides along the track of the inclined groove 33. Since the support plate 41 is linearly limited in the horizontal direction by the rectangular groove, therefore, the round rod 42 can only drive the support plate 41 to move horizontally in a straight line in the direction of the drainage tube body 7 along the track of the inclined groove 33. Subsequently, the support plate 41 drives the arc gasket 43 to move in the same direction through the T-shaped groove 44, so that several arc gaskets 43 are all attached to the outer wall of the drainage tube body 7, thereby fixing the position of the drainage tube body 7 inside the support block 2, and further reducing the occurrence of the phenomenon of the drainage tube body 7 being disconnected; When the arc gasket 43 moves to the predetermined position and stably clamps the drainage tube body 7, at this time, the operator releases the pressing on the pressing block 34, so that the two pressing blocks 34 move in opposite directions under the action of the elastic force of the elastic member 35, and then drive the tooth block 36 to reset through the pressing block 34. After the tooth block 36 is reset, it will re-engage into the inside of the tooth plate 37, so as to fix the position of the square block 31 after it moves downward through the engagement of the tooth block 36 and the tooth plate 37, and further achieve the effect of stably fixing the drainage tube body 7 with different diameters according to different downward distances of the square block 31; When the patient makes movements such as raising the hand or turning over, at this time, the drainage tube body 7 may be slightly pulled. Due to the clamping of the outer wall of the drainage tube body 7 by several arc gaskets 43, the friction force and the contact area between the two will be increased. Therefore, when the drainage tube body 7 is pulled by an external force, it will drive several arc gaskets 43 to move upward, thereby making up for the pulling distance of the drainage tube body 7. When one of the arc gaskets 43 moves upward for a certain distance, the metal T-shaped block on one side thereof will abut against the button 5, thereby pressing the button 5, and then the button 5 drives the circuit inside the support block 2 to close after being pressed, so that the current of the closed circuit is transmitted into the warning component 6, and then drives the warning component 6 to emit an alarm, thereby reminding the patient through the alarm sound to prevent the drainage tube body 7 from being pulled excessively and causing the tube to be disconnected, and further improving the practicability of the device.
