Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a drainage suction clamp for minimally invasive chest surgery. Background Art

[0002] In the field of minimally invasive chest surgery, the drainage operation is an important part of postoperative care. The correct placement and fixation of the drainage tube play a key role in discharging the liquid and gas in the thoracic cavity and promoting wound healing. Currently, various drainage suction clamps are widely used clinically to fix the drainage tube to ensure the smooth progress of the drainage process;

[0003] However, there are still some problems to be solved urgently in the actual application of the existing drainage suction clamps. During the operation, blood and body fluids will continuously ooze from the reserved window of the patient's chest drainage tube. In the currently used device, since the skin patch is directly pasted on the skin at the wound, there are no effective anti-backflow and absorption measures, and the oozing blood and body fluids are likely to enter the patient's thoracic cavity through the wound. This not only may cause wound infection, increase the patient's pain and recovery time, but also may lead to complications such as fluid accumulation and blood accumulation in the thoracic cavity, affecting the surgical effect and even threatening the patient's life and health. Summary of the Invention

[0004] The main object of the present invention is to propose a drainage suction clamp for minimally invasive chest surgery, aiming to solve the problem that in minimally invasive chest surgery, the skin patch of the existing drainage suction clamp is pasted on the skin at the reserved window of the drainage tube, and it cannot effectively handle the blood and body fluids oozing from the wound, and it is easy for them to flow back into the patient's thoracic cavity, causing infection and complications.

[0005] To solve the above problems, the present invention proposes a drainage suction clamp for minimally invasive chest surgery, including a skin patch and a surface fixing piece A pasted and fixed on the outer wall of the top end of the skin patch. Tube holes are provided inside the centers of both the skin patch and the surface fixing piece A. Through openings are provided at the front ends of the centers of the skin patch and the surface fixing piece A. The rear end of the through opening is connected to the tube hole, and when the through opening expands outward, the tube hole can be synchronously expanded. An arc-shaped fixing piece is fixed to the top end of the surface fixing piece A. An elastic clamping sleeve is fixed to the top end of the arc-shaped fixing piece. The elastic clamping sleeve is vertically coincident with the center of the tube hole. A self-provided absorption device is provided at the bottom end of the skin patch.

[0006] In one embodiment, the self - contained absorption device includes a widened drainage tampon, a circular absorption cotton sheet, an absorption round hole, and a storage cotton sheet. An absorption round hole is provided inside the center of the circular absorption cotton sheet, and a through - type opening is also connected to the front end of the absorption round hole. The circular absorption cotton sheet is pasted at the center of the bottom end of the skin adhesive patch, and the absorption round hole is located outside the bottom end of the tube hole. The rear end of the circular absorption cotton sheet is connected to a widened drainage tampon, and the rear end of the widened drainage tampon is connected to a storage cotton sheet.

[0007] In one embodiment, the diameter of the absorption round hole is larger than the diameter of the tube hole, and the absorption round hole is perpendicularly coincident with the diameter of the tube hole. The rear end of the widened drainage tampon is located behind the outer wall of the rear end of the skin adhesive patch.

[0008] In one embodiment, the self - contained absorption device further includes a storage cover and a sealing piece. The top end of the storage cover is provided with an opening, and the storage cover is sleeved outside the storage cotton sheet. A sealing piece is arranged inside the opening at the top end of the storage cover.

[0009] In one embodiment, an anti - allergic adhesive is provided on the outer wall of the bottom end of the skin adhesive patch, and the skin adhesive patch is pasted on the skin at the reserved wound of the patient's chest drainage tube through the anti - allergic adhesive. A plurality of ventilation holes are densely arranged at equal intervals inside the skin adhesive patch.

[0010] In one embodiment, the front end of the elastic clamping sleeve is provided with an opening, and the elastic clamping sleeve can expand outward or contract inward through the front - end opening. A protective inner pad is pasted on the arc - shaped inner wall of the elastic clamping sleeve, and the protective inner pad is made of medical - grade soft silicone.

[0011] In one embodiment, a tightening and fixing adhesive strap is also pasted and fixed on the outer wall of the left end of the elastic clamping sleeve. After the elastic clamping sleeve is sleeved outside the drainage tube, it can be contracted through the front - end opening. After the elastic clamping sleeve is closely attached to the outer wall of the drainage tube through the protective inner pad, it can be tightened and fixed through the tightening and fixing adhesive strap to ensure that the elastic clamping sleeve tightly clamps the outside of the drainage tube through the protective inner pad.

[0012] In one embodiment, a watch fixing piece B is provided at the rear end of the watch fixing piece A. The watch fixing piece B is pasted and fixed on the outer wall of the top end of the skin adhesive patch. Tube guiding and fixing blocks are arranged on both the front and rear sides of the center of the outer wall of the top end of the watch fixing piece B. Arc - shaped grooves are arranged inside both of the tube guiding and fixing blocks, and the opening direction of the arc - shaped grooves is upward.

[0013] In one embodiment, tube fixing adhesive straps are arranged on the outer wall of the left end of the tube guiding and fixing block at the rear side of the center of the watch fixing piece B and on the outer wall of the right end of the tube guiding and fixing block at the front side of the center. After the drainage tube is fixed by the elastic clamping sleeve, it can be bent backward into a horizontal state, and the horizontal drainage tube can be directly placed in the arc - shaped grooves inside the two tube guiding and fixing blocks and fixed through the tube fixing adhesive straps.

[0014] Beneficial effects: The technical solution of the present invention adds a new self-absorbing device at the bottom of the skin patch. After the skin patch is pasted on the skin at the reserved wound of the patient's chest drainage tube through the anti-allergic adhesive, at this time, the drainage tube passes through the skin patch and the tube hole inside the surface fixing piece A, and the elastic clamping sleeve on the surface fixing piece clamps and fixes the outside of the drainage tube to ensure the normal and stable use of the drainage tube. However, during the operation, blood and body fluids will continuously ooze from the reserved window of the patient's chest drainage tube. Because the skin patch is pasted on the skin at this place, the oozing blood and body fluids will enter the patient's thoracic cavity through the wound. The self-absorbing device can continuously absorb the blood and body fluids oozing from the reserved wound of the drainage tube, and guide the absorbed blood and body fluids outward through the widened absorbent cotton pad, thus avoiding the accumulation of blood and body fluids at the wound and reducing the risk of infection, providing a cleaner and safer recovery environment for the patient. At the same time, the storage cover and sealing piece design of the self-absorbing device facilitate the storage and sealing of the storage cotton pad, prevent the overflow of the absorbed blood and body fluids from polluting the surrounding environment, and also facilitate the timely replacement of the storage cotton pad. Moreover, the device has a simple structure and low cost, does not require additional complex operations and equipment, and can be easily operated by medical staff, which helps to improve the nursing efficiency, reduce the work burden, and further improve the overall quality of chest minimally invasive surgery drainage care.

[0027] The present invention provides a drainage suction clamp for minimally invasive chest surgery as shown in Figures 1-5 which includes a skin adhesive patch 8 and a surface fixing piece A9 adhesively fixed to the top outer wall of the skin adhesive patch 8. Tube holes 2 are provided inside the centers of both the skin adhesive patch 8 and the surface fixing piece A9. Through openings 13 are provided at the front ends of the centers of the skin adhesive patch 8 and the surface fixing piece A9. The rear end of the through opening 13 is connected to the tube hole 2, and when the through opening 13 expands outwards, the tube hole 2 can be synchronously expanded. An arc-shaped fixing piece 3 is fixed to the top of the surface fixing piece A9. The arc-shaped fixing piece 3 can stably connect the elastic clamping sleeve 10 to the surface fixing piece A9, ensuring that the elastic clamping sleeve 10 is vertically coincident with the center of the tube hole 2, so that the elastic clamping sleeve 10 can accurately clamp the drainage tube. An elastic clamping sleeve 10 is fixed to the top of the arc-shaped fixing piece 3, and the elastic clamping sleeve 10 is vertically coincident with the center of the tube hole 2. The surface fixing piece A9 is adhesively fixed to the top outer wall of the skin adhesive patch 8. The tube hole 2 at the center cooperates with the tube hole 2 of the skin adhesive patch 8 to allow the drainage tube to pass through smoothly. The arc-shaped fixing piece 3 at the top is used to fix the elastic clamping sleeve 10 and provides an installation basis for the elastic clamping sleeve 10. An anti-allergic adhesive is provided on the bottom outer wall of the skin adhesive patch 8, and the skin adhesive patch 8 is adhered to the skin at the reserved wound of the patient's chest drainage tube through the anti-allergic adhesive. A plurality of air holes 11 are densely arranged at equal intervals inside the skin adhesive patch 8. The skin adhesive patch 8 is adhered to the skin at the reserved wound of the patient's chest drainage tube through the anti-allergic adhesive at the bottom, playing a role in fixing the entire device. The tube hole 2 inside its center provides a passing channel for the drainage tube. The through opening 13 at the front end expands outwards to expand the tube hole 2, facilitating the sliding of the drainage tube. The plurality of air holes 11 densely arranged at equal intervals inside can ensure skin ventilation and improve the comfort of the patient.

[0028] As shown in Figure 1 、 Figure 2 and Figure 3As shown, the front end of the elastic clamping sleeve 10 is open, and the elastic clamping sleeve 10 can expand outward or contract inward through the front opening. A protective inner pad 1 is pasted on the arc-shaped inner wall of the elastic clamping sleeve 10. The protective inner pad 1 is made of medical-grade soft silicone. The front opening of the elastic clamping sleeve 10 can expand outward or contract inward, which is convenient for sleeving it onto the outside of the drainage tube. After the tightening and fixing adhesive strap 12 is contracted, the medical-grade soft silicone protective inner pad 1 pasted on the inner wall closely fits and clamps the drainage tube, playing a role in fixing the drainage tube. The protective inner pad 1 can prevent the drainage tube from being clamped and damaged. A tightening and fixing adhesive strap 12 is also fixedly pasted on the outer wall of the left end of the elastic clamping sleeve 10. After the elastic clamping sleeve 10 is sleeved onto the outside of the drainage tube, it can be contracted through the front opening. After the elastic clamping sleeve 10 closely fits the outer wall of the drainage tube through the protective inner pad 1, it can be tightened and fixed through the tightening and fixing adhesive strap 12 to ensure that the elastic clamping sleeve 10 tightly clamps the outside of the drainage tube through the protective inner pad 1. After the elastic clamping sleeve 10 is sleeved onto the drainage tube and contracted through the front opening, the tightening and fixing adhesive strap 12 is pasted on the outer wall of the right end of the elastic clamping sleeve 10, which can maintain the tightened state of the elastic clamping sleeve 10 and ensure the stable clamping of the drainage tube. A watch fixing piece B7 is provided at the rear end of the watch fixing piece A9, and the watch fixing piece B7 is fixedly pasted on the top outer wall of the skin sticking piece 8. Pipe guiding and fixing blocks 5 are provided on both the front and rear sides at the center of the top outer wall of the watch fixing piece B7. Arc-shaped grooves are provided inside both of the two pipe guiding and fixing blocks 5, and the opening directions of the arc-shaped grooves face upward. The upward-facing opening of the arc-shaped groove is used to place the drainage tube bent into a horizontal state, playing a role in guiding and positioning the drainage tube. Pipe fixing adhesive straps 4 are provided on the left outer wall of the pipe guiding and fixing block 5 at the rear side of the center of the watch fixing piece B7 and on the right outer wall of the pipe guiding and fixing block 5 at the front side of the center. After the drainage tube is fixed by the elastic clamping sleeve 10, it can be bent backward into a horizontal state, and the horizontal drainage tube can be directly placed in the arc-shaped grooves inside the two pipe guiding and fixing blocks 5 and fixed by the pipe fixing adhesive straps 4. The pipe fixing adhesive straps 4 are used to further fix the drainage tube placed in the arc-shaped groove to prevent the drainage tube from shifting.

[0029] As Figure 1 , Figure 2 and Figure 3As shown, the design of this drainage suction clamp for minimally invasive chest surgery aims to provide a reliable, convenient, and comfortable way of fixing and guiding for the drainage operation after minimally invasive chest surgery. First, after the drainage tube has been inserted by the doctor into the reserved wound of the patient's chest drainage tube, it is installed using the design features of the skin patch 8. By tearing off the protective film at the bottom of the skin patch 8, the through-opening 13 is sleeved on the drainage tube outside the skin, and then the skin patch 8 is pushed towards the drainage tube to make the drainage tube smoothly slide into the tube hole 2. Subsequently, the skin patch 8 is firmly adhered to the skin using the anti-allergic adhesive. During this process, the ventilation holes 11 can ensure skin breathability and reduce patient discomfort. Next, for the elastic clamping sleeve 10, it is expanded through the front-end opening and then sleeved outside the drainage tube, and then tightened by means of the tightening and fixing adhesive strap 12, so that the elastic clamping sleeve 10 closely adheres to and clamps the drainage tube through the protective inner pad 1 made of medical-grade soft silicone. The protective inner pad 1 can not only prevent the drainage tube from being damaged but also enhance the clamping stability. Finally, considering the subsequent placement and fixation of the drainage tube, since the initially clamped drainage tube is in a vertically upward state, it needs to be bent backward into a horizontal state and placed in the arc-shaped grooves of the two tube guiding and fixing blocks 5 on the surface fixing piece B7, and the tube fixing adhesive strap 4 is used for further fixation. This design not only makes the position of the drainage tube stable but also facilitates the drainage operation. Each component works together to provide all-round support and guarantee for the drainage process of minimally invasive chest surgery.

[0030] As Figure 1 , Figure 4 and Figure 5As shown, a self - contained absorption device 6 is provided at the bottom end of the skin patch 8. The self - contained absorption device 6 includes a widened drainage cotton strip 16, a circular absorption cotton sheet 17, an absorption round hole 18, and a storage cotton sheet 19. An absorption round hole 18 is provided inside the center of the circular absorption cotton sheet 17, and a through - type opening 13 is also connected to the front end of the absorption round hole 18. The circular absorption cotton sheet 17 is pasted at the center of the bottom end of the skin patch 8, and the absorption round hole 18 is located outside the bottom end of the tube hole 2. The widened drainage cotton strip 16 is connected to the rear end of the circular absorption cotton sheet 17, and the storage cotton sheet 19 is connected to the rear end of the widened drainage cotton strip 16. The self - contained absorption device 6 further includes a storage cover 14 and a sealing piece 15. The top end of the storage cover 14 is open, and the storage cover 14 is sleeved outside the storage cotton sheet 19. A sealing piece 15 is provided inside the top - end opening of the storage cover 14. The design of the position of the rear end of the widened drainage cotton strip 16 at the rear side of the outer wall of the rear end of the skin patch 8 not only avoids interfering with the normal placement and fixation of the drainage tube, but also can use gravity to assist the liquid to flow better to the storage cotton sheet 19. The storage cover 14 is sleeved outside the storage cotton sheet 19, and its top - end opening facilitates the installation and replacement of the storage cotton sheet 19. When the storage cotton sheet 19 is saturated with absorption, medical staff can open the sealing piece 15 and easily take out and replace the storage cotton sheet 19. The presence of the sealing piece 15 can prevent the blood and body fluids absorbed in the storage cotton sheet 19 from overflowing, avoid polluting the surrounding environment of the patient, and maintain the cleanliness and hygiene of the entire nursing environment. Through such a coordinated working mechanism, the self - contained absorption device 6 effectively realizes the functions of absorbing, guiding, and storing the exudates from the reserved wound of the drainage tube.

[0031] As Figure 1 , Figure 4 and Figure 5As shown, the diameter of the absorption round hole 18 is larger than that of the tube hole 2, and the absorption round hole 18 is vertically coincident with the tube hole 2 in diameter. The rear end of the widened drainage cotton strip 16 is located at the rear side of the outer wall of the rear end of the skin adhesive patch 8. The design purpose of the self-prepared absorption device 6 is to solve the problems of blood leakage and fluid leakage at the wound reserved by the drainage tube after minimally invasive chest surgery, and to provide a clean and safe recovery environment for the patient's wound. When the skin adhesive patch 8 is pasted on the skin at the wound reserved by the drainage tube of the patient through the anti-allergic adhesive, the drainage tube passes through the tube hole 2 inside the skin adhesive patch 8 and the surface fixing piece A9, and the whole device is in a normal working state. At this time, the blood and body fluid exuded from the wound reserved by the drainage tube will flow downward naturally due to factors such as gravity and the pressure difference between the wound and the outside world. Since the circular absorption cotton sheet 17 is pasted at the center of the bottom end of the skin adhesive patch 8, and the absorption round hole 18 is located outside the bottom end of the tube hole 2, and at the same time the diameter of the absorption round hole 18 is larger than that of the tube hole 2 and is vertically coincident with it, the exuded blood and body fluid will first converge at the through-opening 13 at the front end of the absorption round hole 18. The through-opening 13 is like an "entrance", and its design at the position opposite to the tube hole 2 enables the exudate to smoothly enter the absorption round hole 18. The blood and body fluid entering the absorption round hole 18 are then absorbed by the circular absorption cotton sheet 17. The circular absorption cotton sheet 17 has good water absorption and can quickly adsorb and hold a certain amount of exudate. Then, the absorbed liquid is guided outward through the widened drainage cotton strip 16 connected to the rear end. The widened drainage cotton strip 16 plays the role of a "bridge". It has a large cross-sectional area and can ensure that the liquid flows backward quickly and smoothly. The storage cotton sheet 19 connected to the rear end of the widened drainage cotton strip 16 serves as the final "storage container". The storage cotton sheet 19 has a large absorption capacity and can store a large amount of blood and body fluid guided over, thus avoiding the accumulation of exudate around the wound.

[0032] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
