Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to a chest cavity pipeline positioning device for thoracic surgery nursing. Background Art

[0002] Thoracic tube positioning is of great significance in medical practice. It involves the correct placement of multiple tubes and catheters in the chest cavity to ensure treatment effect and patient safety. Thoracic tubes mainly include endotracheal tubes, tracheotomy tubes, central venous tubes, PICC tubes, pulmonary artery floating catheters, chest drainage tubes, etc. The positions of these tubes in the chest cavity are different, and each has its specific function. Thoracic tube positioning is a complex and delicate medical operation that requires doctors to have rich professional knowledge and clinical experience. Correct tube positioning is crucial to the treatment effect and life safety of patients.

[0003] During the positioning process of the various types of tubes mentioned above, X-rays, B-ultrasound and other imaging technologies are usually used to assist in positioning. These technologies can provide clear images of the internal structure of the chest cavity, helping doctors to accurately determine the position and depth of the tube. At the same time, doctors also need to choose the appropriate tube type and insertion method according to the patient's specific situation and lesion characteristics. For example, the insertion position of the chest drainage tube is usually at the position of the chest ribs. After the drainage tube is inserted, it can effectively discharge the effusion and gas in the chest cavity, significantly improve respiratory function, and effectively prevent and treat infection. After the chest tube is positioned, it needs to be fixed again with a dressing. However, when the patient turns over, sits, lies or walks, the drainage tube may cause a noticeable feeling of falling or pulling. This discomfort may increase the tension of the wound, and then cause the wound to crack, which not only delays the healing process, but also leads to poor recovery sensation. Summary of the invention

[0004] The purpose of the present invention is to provide a chest tube positioning device for thoracic surgery nursing, which can effectively reduce the discomfort caused by the falling or pulling of the drainage tube due to the patient's daily activities, and the downward pulling force will not directly act on the wound, reducing the tearing situation. For patients who need long-term indwelling chest tubes, it greatly improves the patient's quality of life and reduces the risk of secondary trauma caused by improper tube management.

[0005] The technical solution adopted by the present invention is as follows:

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0042] Example 1

[0043] Please see attached Figure 1 As shown, the present invention provides a chest cavity pipeline positioning device for thoracic surgery nursing, comprising a first dressing part 1, a medical rubber ring 2, a second dressing part 5, a catheter fixing 6, a clamping ring assembly 3 and a clamping strip 4 arranged on the clamping ring assembly 3, the first dressing part 1 covers the medical rubber ring 2 and is attached to the skin, one end of the clamping strip 4 can be inserted into the interior of the clamping ring assembly 3 and change the clamping degree of the clamping ring assembly 3, the clamping ring assembly 3 is sleeved on the medical rubber ring 2, clamps the medical rubber ring 2 and the chest cavity pipeline and keeps them fixed, the second dressing part 5 and the first dressing part 1 have a spacing, the catheter fixing 6 is arranged on the second dressing part 5, the chest cavity pipeline passes through the clamping ring assembly 3 and is clamped on the catheter fixing 6, and a reserved part of the chest cavity pipeline is located between the second dressing part 5 and the first dressing part 1, so that the chest cavity pipeline pre-stored between the second dressing part 5 and the first dressing part 1 is in a relaxed state.

[0044] Please see attached Figure 1 or Figure 7 As shown, a perforated line 7 is provided at the connection position between the first dressing part 1 and the second dressing part 5, allowing the first dressing part 1 and the second dressing part 5 to be separated and adapted to be placed at different positions on the skin, wherein the connection structure between the first dressing part 1 and the second dressing part 5 can be made of a material that does not have the ability to fit, and two perforated lines 7 can also be provided, that is, in addition to the above-mentioned position close to the first dressing part 1, an additional perforated line 7 can also be provided at a position close to the second dressing part 5.

[0045] Specifically, the first dressing part 1 and the second dressing part 5 are both medical sterile breathable dressings, which are in smooth contact with the skin surface.

[0046] More specifically, for ease of use, the first dressing part 1 and the medical rubber ring 2 are provided with a slit, and the first dressing part 1 and the medical rubber ring 2 are put on the chest tube along the slit, and then the first dressing part 1 is attached to the skin. Since the first dressing part 1 and the second dressing part 5 can be separated by the punch line 7, the separation distance between the first dressing part 1 and the second dressing part 5 can be flexibly adjusted according to actual operating conditions, and a part of the chest tube between the two dressing parts can be reserved to keep the chest tube in a relaxed state. When the chest tube is accidentally pulled, the reserved part of the tube will fall out naturally, effectively reducing the discomfort of the drainage tube falling or pulling caused by the patient's daily activities.

[0047] Please see attached Figure 2 As shown, the medical rubber ring 2 is configured as an annular disc 201, a cavity 202 is provided at the bottom of the disc 201, and the side surface thereof protrudes so that the bottom surface is higher than the epidermis, and the cavity 202 can be filled with a suitable sterile cotton compress, a plug hole is provided in the middle of the disc 201 adapted to the chest cavity duct, a ring sleeve 203 is provided on the top surface of the disc 201 and around the aperture of the plug hole, and the clamping ring assembly 3 is clamped on the outside of the ring sleeve 203 and clamped.

[0048] Specifically, the medical rubber ring 2 is heightened by the provided disc 201 so as to be higher than the skin surface. When applying the first dressing part 1 to the patient, the medical rubber ring 2 is filled with a suitable sterile cotton compress to quickly absorb wound exudate. In addition, the design of the ring sleeve 203 enables the clamping ring assembly 3 to clamp and tighten the chest tube and the ring sleeve 203. When the chest tube falls, the ring sleeve 203 and the first dressing part 1 adhered to the epidermis can relieve force to a certain extent, so that the downward pulling force will not directly act on the wound, thereby reducing tearing.

[0049] More specifically, the ring sleeve 203 is made of medical rubber material, which is both soft and tough. It can fit the patient's skin closely and reduce the discomfort caused by friction. It is worth mentioning that the combination of the first dressing part 1 and the medical rubber ring 2 ensures that the patient can remain fixed in different body positions and will not shift or loosen due to the patient's activities. This structure greatly improves the quality of life of patients who need long-term indwelling chest tubes and reduces the risk of secondary trauma caused by improper tube management.

[0050] Please see attached Figure 2-Figure 4As shown, the clamping ring assembly 3 includes two inferior arc ring plates 301 arranged opposite to each other; and a connecting ring plate 302, both ends of the connecting ring plate 302 are connected to the common end of the two inferior arc ring plates 301, and the inferior arc ring plates 301 can elastically move away from or close to each other, one of the inferior arc ring plates 301 is provided with a first wrench 303 extending obliquely outward, and the other inferior arc ring plate 301 is provided with a second wrench 304 consistent with the above structure. Specifically, the two inferior arc ring plates 301 form an elastic structure through the connecting ring plate 302, and can return to their original state after moving away from or close to each other.

[0051] Please see attached Figure 3-Figure 5 As shown, the clamping strip 4 is disposed on the first wrench 303 and faces the second wrench 304;

[0052] An adjustment groove 306 is provided on the minor arc ring plate 301 located at the second wrench 304, and one end portion of the clamping strip 4 is inserted into the adjustment groove 306 and moves relative to the minor arc ring plate 301;

[0053] A fixing block 310 is provided on the minor arc ring plate 301 of the second wrench 304 , and an adjusting fastener 307 is provided on the same side and above the adjusting slot 306 , and the adjusting fastener 307 cooperates with the clamping strip 4 to lock or loosen.

[0054] Please see attached Figure 6 As shown, a connecting piece 311 is provided between the adjusting fastener 307 and the fixing block 310 , and a flexible connection is formed between the adjusting fastener 307 and the fixing block 310 through the connecting piece 311 .

[0055] Specifically, the flexibility between the adjusting fastener 307 and the fixing block 310 comes from the connecting piece 311, so that the adjusting fastener 307 can return to its original state after the force of deformation or displacement disappears.

[0056] Please see attached Figure 3 or Figure 4 As shown, the top of the adjusting fastener 307 extends upward to form a buckle plate 308, and the bottom thereof extends downward to form a buckle tooth 309, which is located on the second wrench 304, and a through groove 305 is provided corresponding to the buckle plate 308. The clamping strip 4 has clamping teeth 401 arranged at equal intervals, and a tooth groove 402 is between the two clamping teeth 401. When one end portion of the clamping strip 4 is located inside the adjusting groove 306, the buckle tooth 309 is stuck in the tooth groove 402.

[0057] Specifically, when the clamping strip 4 is buckled in the adjustment groove 306, the buckle teeth 309 on the adjustment fastener 307 are stuck in the tooth groove 402 of the clamping strip 4, so that the two inferior arc ring plates 301 are constrained and cannot be moved away or relaxed. When the clamping strip 4 needs to be removed, the buckle plate 308 is pressed to make the buckle plate 308 deviate toward the through groove 305, and the buckle teeth 309 at the bottom of the adjustment fastener 307 are disengaged from the tooth groove 402, so that the clamping strip 4 is in a relaxed state, and the clamping ring assembly 3 is removed. Since the adjustment fastener 307 is a flexible connection, it can be used again after being reset.

[0058] According to the above structure, after the chest tube is covered along the slit, the clamping strip 4 is inserted into the adjustment groove 306, and the first wrench 303 and the second wrench 304 are pinched at the same time to force the clamping strip 4 to move toward the inside of the adjustment groove 306. As the clamping strip 4 moves toward the inside of the adjustment groove 306, the gap between the first wrench 303 and the second wrench 304 gradually decreases, and vice versa, the gap between the first wrench 303 and the second wrench 304 increases, thereby adjusting the degree of fixation of the chest tube by the clamping ring assembly 3.

[0059] Please see attached Figure 7 or Figure 8 As shown, the catheter fixing 6 includes two tube clamps 601 arranged opposite to each other, and the tube clamps 601 are provided with notches for inserting the chest tube. A patch 602 is provided between the two tube clamps 601, and one end of the patch 602 is fixed and sticky, and the other end is movable and sticky. When the chest tube is inserted, the movable end of the patch 602 is folded over and adhered to the fixed end.

[0060] Based on the above structure, after the first dressing part 1 is fixed, the second dressing part 5 is attached to the epidermis at a suitable position, leaving part of the chest tube and clamping the tube body on the tube clamp 601, and then the patch 602 is folded and glued to fix it, restraining the chest tube to prevent dislocation, and completing the coordination and fixation of the first dressing part 1 and the second dressing part 5.

[0061] The working principle of the present invention is as follows: the first dressing part 1 and the medical rubber ring 2 are put on the chest tube along the slit, and then the first dressing part 1 is attached to the skin. Since the first dressing part 1 and the second dressing part 5 can be separated by the punching line 7, the separation distance between the first dressing part 1 and the second dressing part 5 can be flexibly adjusted according to the actual operation situation. After the chest tube is put on along the slit, the clamping strip 4 is clamped into the adjustment groove 306, and the first wrench 303 and the second wrench 304 are pinched at the same time to force the clamping strip 4 to move toward the inside of the adjustment groove 306. As the clamping strip 4 moves toward the inside of the adjustment groove 306, the first wrench 303 and the second wrench 304 are pressed together. 4 gradually decreases, and vice versa, the gap between the first wrench 303 and the second wrench 304 becomes larger, so as to adjust the degree of fixation of the chest tube by the clamp assembly 3. Finally, after the first dressing part 1 is fixed, the second dressing part 5 is attached to the epidermis at a suitable position, leaving part of the chest tube and clamping the tube body on the tube clamp 601, and then the patch 602 is folded and glued to fix it, so as to restrain the chest tube and prevent dislocation, and complete the coordination and fixation of the first dressing part 1 and the second dressing part 5. When replacing, it is necessary to remove the second dressing part 5 first, then remove the clamp assembly 3, and finally uncover the first dressing part 1 for replacement.

[0062] Example 2

[0063] The difference between it and Example 1 is only in the different usage, specifically:

[0064] When medical staff use the device, they can first adjust the patient's body position, and then apply the first dressing part 1 and the second dressing part 5 to the required positions of the body respectively, wherein the first dressing part 1 is applied first, and then the skin below the first dressing part 1 is slightly squeezed downwards, and then the second dressing part 5 is applied, and then the squeezing process is released. When the body relaxes, the skin relaxes, so that the first dressing part 1 and the second dressing part 5 are in a relaxed state (similar to the process of turning the wrist over and straightening it). When the patient generally turns over or walks slightly, the pipeline will give priority to applying pressure to the second dressing part 5. Due to the slight movement and the space between the first dressing part 1 and the second dressing part 5, In a relaxed state, the second auxiliary material part 5 can bear most of the traction, and the relaxed state between the two can share the feeling of falling caused by slight movements, that is, it is not easy to cause traction to the first dressing part 1. When there is a violent movement or the chest tube is pulled, its end is pulled strongly, the pulling force is first transmitted to the second dressing part 5 and then to the first dressing part 1. Due to the large pulling force, when the force exceeds the bearing limit of the perforated line 7, the perforated line 7 breaks quickly, and the perforated line 7 breaks, so that the first dressing part 1 is separated from the second dressing part 5. At this time, the second dressing part 5 bears all the pressure, thereby reducing the pressure of the first dressing part 1 for the patient.

[0065] Example 3

[0066] The difference between it and Example 2 is only the application method, specifically:

[0067] Generally, there is a certain elasticity between the first dressing part 1 and the second dressing part 5 (film dressing). The patient's body position can be adjusted first, and then the first dressing part 1 and the second dressing part 5 are applied to the required positions of the body respectively. The first dressing part 1 is applied first, and then the skin below the first dressing part 1 is slightly squeezed upwards, and then the second dressing part 5 is applied. After the application is completed, the skin recovers slightly, and the first dressing part 1 and the second dressing part 5 are tightened (so that it is easier to be pulled apart when subjected to a large pull. In addition, in order to achieve the effect of being easier to break, The size of the holes in the perforated line 7 should meet the requirement of being pulled apart, that is, a slight pull will not easily cause the dressing to be pulled apart, and the protective effect can be achieved by relying solely on the elasticity between the dressings. In the case of a larger pulling force, the force transmission is larger, and the dressing can be smoothly pulled apart). However, the skin between the two is loose. Therefore, when subjected to a slight pulling force, the dressing connection has a certain elasticity, and the elasticity cooperates with the loose skin, and the effect is basically the same as in Example 2. When pulled violently, the perforated line 7 is more likely to break, and the subsequent process is basically the same as in Example 2.

[0068] The size of the holes in the perforated line 7 in the above embodiments 2 and 3 should satisfy the requirement that it is not easily broken by slight pulling, and when pulled harder, the instantaneous pulling force increases, so it can be broken. The specific parameter design can be fine-tuned according to the material selection. Of course, other material designs that can meet the above requirements should fall within the protection scope of this application.

[0069] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
