DETAILED DESCRIPTION
[0026] The utility model will be further explained in connection with the drawings.
[0027] Referring to Figures 1-5 The thoracic cavity drainage tube fixer of the embodiment includes clamping assembly 1, and the clamping assembly 1 has two, and the two clamping assemblies 1 can mutually fit in front and back to clamp and fix the drainage tube. Each clamping assembly 1 includes clamping piece 11 and binding piece 12.
[0028] In the embodiment, the lower end of clamping piece 11 has outwardly extended pressing sheet 111, and the pressing sheet 111 is a sheet structure and is a long rectangle, and the pressing sheet 111 is used to provide the adhesive base for the adhesive tape 2. The splicing surface of clamping piece 11 has accommodating groove 112 for accommodating the drainage tube, and the cross section of accommodating groove 112 is semicircular, and this shape can better adapt to the shape of the drainage tube. The upper end of clamping piece 11 has extruding portion 113 that extends into accommodating groove 112 and is used to extrude and fix the drainage tube, and the extruding portion 113 of the embodiment is crescent-shaped, and the crescent-shaped design ingeniously utilizes the mechanical advantage of the arc structure, can tightly fit the circular outer wall of the drainage tube, increases the contact area, makes the extruding force evenly distribute, effectively limits the displacement of the drainage tube in the vertical direction, and eliminates its up-and-down movement.
[0029] In this embodiment, the binding member 12 is a flexible structure, and the specific material can be adhesive tape. One end of the binding member 12 is connected to the side of the clamping member 11 away from the receiving groove 112, and the other end is a free end. One side of the binding member 12 is an adhesive surface, which is used to bond and fix it to the clamping member 11 of another clamping assembly 1.
[0030] In this embodiment, an adhesive layer 122 is provided on one side of the fastener 12, and the fastener 12 forms an adhesive surface through the adhesive layer 122. In this embodiment, the adhesive layer 122 is glue. Besides glue, other structures, such as hook and loop fasteners, can also be considered for the adhesive layer 122 in other embodiments. It is worth mentioning that if the adhesive layer 122 on the side of the fastener 12 is a hook and loop fastener with burrs, a corresponding hook and loop fastener with rounded burrs should be provided on the outside of the clamping member 11 to facilitate bonding of the fastener 12; similarly, if the adhesive layer 122 on the side of the fastener 12 is a hook and loop fastener with rounded burrs, a corresponding hook and loop fastener with burrs should be provided on the outside of the clamping member 11.
[0031] When using the chest drainage tube fixation device of this utility model, firstly, medical staff hold the drainage tube and place it into the receiving groove 112 of one of the clamping components 1.
[0032] Next, pick up another clamping component 1 to assemble the two clamping components 1 together. At this time, the two crescent-shaped extrusion parts 113 apply force simultaneously to tightly clamp the drainage tube, thereby restricting the drainage tube from moving vertically relative to the clamping components 1.
[0033] Subsequently, the free ends of the two binding members 12 are pulled towards the clamping member 11 of the opposite clamping component 1 and tightly bonded to the clamping member 11 of the opposite clamping component 1 using the adhesive surface, so that the two clamping components 1 are tightly locked together to form a whole, and the drainage tube is fixed to the two clamping components 1.
[0034] Finally, select four sections of adhesive tape 2 and attach them to the upper end of the pressure plate 111 in a crisscross pattern. During adhesion, the two sections of tape 2 in the front-to-back direction are individually adhered to each of the two pressure plates 111, while the two sections of tape 2 in the left-to-right direction are simultaneously adhered to both pressure plates 111. Furthermore, the pressure plate 111 should be positioned in the middle of the tape 2 during adhesion. After the tape 2 is adhered to the pressure plate 111, the portion of the tape 2 extending beyond the pressure plate 111, along with the pressure plate 111 itself, is then applied to the patient's skin. This secures the fixator to the patient's body surface.
[0035] As can be seen from the above, the chest drainage tube fixator proposed in this utility model effectively solves many drawbacks of the traditional tape fixation method through two combinable clamping components 1.
[0036] After using the fixer, the drainage tube can be stably clamped in the accommodating groove 112 of the clamping assembly 1, the crescent-shaped extrusion part 113 of the clamping assembly 1 provides reliable vertical limiting force, greatly reduces the risk of accidental movement and displacement of the drainage tube caused by changes in the patient's body position or daily activities, and guarantees the smoothness of the drainage process. Moreover, the adhesive tape is no longer in direct contact with the drainage tube, avoiding the residue of the glue liquid, which enables medical staff to clean the drainage tube more conveniently and efficiently during dressing change, significantly reducing the nursing burden and the infection risk caused by cleaning difficulties.
[0037] In clinical practice, medical staff can quickly master the operation method, compared with the traditional way of relying on rich nursing experience to fix the drainage tube, the fixer can provide a standardized process for nursing work, even if the nursing staff is slightly experienced, the fixing operation can also be accurately completed, improving the overall work efficiency and quality of the nursing team.
[0038] In the embodiment, the splicing surface of the clamping piece 11 has a positioning protrusion 114 protruding outward and a positioning groove 115 matched with the positioning protrusion 114, and the positioning protrusion 114 and the positioning groove 115 are symmetrically arranged on the left and right sides of the accommodating groove 112. Specifically, the positioning protrusion 114 and the positioning groove 115 are both longitudinally spaced multiple. In this way, when the two clamping assemblies 1 are spliced, the positioning protrusion 114 can be embedded in the corresponding positioning groove 115. This effectively prevents the two clamping pieces 11 from being misaligned during splicing, ensuring that the accommodating groove 112 can be accurately connected to enable the drainage tube to be stably clamped in the ideal position. Multiple longitudinally spaced positioning structures also greatly enhance the overall stability after splicing.
[0039] When medical staff frequently check the drainage condition or perform peripheral nursing operations, even if the fixer is accidentally touched, the clamping assembly 1 is not easy to spread or displace, reducing the tedious process of re-adjusting and fixing due to accidental movement of the fixer, to help the smooth progress of the entire treatment process.
[0040] In the embodiment, the clamping piece 11 has a semicircular cross section concentric with the accommodating groove 112. The clamping piece 11 of this shape has a smooth appearance without sharp corners, reducing the risk of accidental scratches on the hands during operation by medical staff, and also avoiding potential harm to the patient's body and clothes.
[0041] In the embodiment, the clamping member 11 is a hollow structure with an open upper end, and a reinforcing plate 116 extending front-to-back is arranged inside the clamping member 11. The hollow structure design can reduce the overall weight of the clamping member 11. Compared with a solid structure, it reduces the amount of material used, making the fixator more lightweight, and whether it is held by medical staff or worn by patients, it will not cause excessive additional burden, improving the comfort of use.
[0042] The front-to-back extending reinforcing plate 116 added inside can play a reinforcing role. The reinforcing plate 116 effectively distributes the pressure from the outside. When the drainage tube is pulled, squeezed by external force, or the fixator is subjected to collision, bending, etc., the reinforcing plate 116 can disperse stress along the front-to-back direction like a framework, preventing the clamping member 11 from being damaged due to uneven stress, such as indentation, fracture, etc., maintaining the integrity of the shape of the clamping member 11, ensuring that the accommodation groove 112 is always in a stable state, and ensuring that the drainage tube is firmly fixed and will not be loose, displaced, etc. affect the drainage effect.
[0043] In the embodiment, the clamping member 11 has a through groove 117 arranged left and right on the side away from the accommodation groove 112, and the non-free end of the binding member 12 is fixedly connected with a connecting part 121 penetrating through the through groove 117 and winding back from the side of the clamping member 11 away from the accommodation groove 112 to the non-free end of the binding member 12. Such arrangement can form a stable connection between the non-free end of the binding member 12 and the clamping member 11.
[0044] In the embodiment, the clamping assembly 1 further comprises a pad 13 covering the splicing surface of the clamping member 11, the inner side surface of the accommodation groove 112, and the lower end surface of the pressing plate 111. In the embodiment, the pad 13 is configured as sterile cotton.
[0045] The sterile cotton pad 13 adds a protective barrier to the process of closed thoracic drainage. It covers the splicing surface of the clamping member 11, which can fill the small gaps when two clamping assemblies 1 are combined to ensure airtightness and prevent external bacteria, dust and other pollutants from invading the surrounding area of the drainage tube, reducing the risk of infection.
[0046] The sterile cotton pad 13 placed on the inner side surface of the accommodation groove 112 can quickly absorb a small amount of body fluid, exudate, etc. that may be contaminated on the outer wall of the drainage tube due to its good water absorption, keeping the surrounding area of the drainage tube dry and preventing the accumulation of liquid to breed bacteria, thereby strengthening the anti-infection line of defense.
[0047] The sterile cotton pad 13 covering the lower end face of the pressing sheet 111 can play a buffering role before the pressing sheet 111 contacts the skin of the patient, avoid direct contact between the pressing sheet 111 and the skin, and improve comfort. In addition, it can also be used to fill small gaps, further ensure the sealing effect, prevent external bacteria, dust and other pollutants from invading the lower side area of the pressing sheet 111, and reduce the risk of infection. In addition, it can quickly absorb the exuded body fluid at the drainage hole, maintain the dryness around the drainage hole, prevent the accumulation of liquid and the breeding of bacteria, and further strengthen the anti-infection line of defense.
[0048] In summary, the utility model discloses a thoracic drainage tube fixing device, which effectively solves the many drawbacks of the traditional adhesive tape fixing thoracic drainage tube mode through a series of carefully designed structural components. From the clamping assembly, two clamping pieces that can be precisely spliced, with the accommodation groove precisely matching the shape of the drainage tube, the crescent-shaped extrusion part stably limiting the vertical displacement, and the outwardly extending pressing sheet providing a reliable basis for adhesive bonding, and the positioning protrusion and the positioning groove ensure accurate splicing, the semicircular cross section of the clamping piece and the hollow reinforced plate structure inside guarantee mechanical properties and also consider lightness and durability. The binding piece is made of flexible adhesive tape material combined with a specific adhesive layer and a connection part design, allowing the two clamping assemblies to be securely locked, convenient and efficient to operate. The pad is made of sterile cotton material and covers all key parts, providing sealing protection, reducing friction, moisture absorption, antibacterial properties, and improving patient comfort in many ways. Overall, the fixing device not only improves the stability and reliability of the drainage tube fixation, reduces the risk of tube detachment and displacement, but also greatly reduces the difficulty and workload of medical care, reduces the risk of infection due to inconvenience in cleaning, improves the patient experience, and is beneficial to clinical practice and widespread application.
