Description

TECHNICAL FIELD

[0001] The utility model belongs to drainage tube technical field, concretely relates to a kind of anti-pressing drainage tube and drainage tube assembly. BACKGROUND

[0002] In clinical nursing in general surgery, thoracic surgery and urology, the indwelling of drainage tube is an important means for draining effusion, gas and promoting wound healing. If the long-term indwelling drainage tube is not fixed properly, it is easy to press the skin around the stoma, causing medical device-related pressure injury, causing pain to the patient and increasing the risk of infection.

[0003] To solve the problem of skin compression by drainage tube, the existing technical solution usually uses a flexible pad (such as foam dressing, non-woven soft pad or hydrocolloid pressure-reducing paste) between the drainage tube body and the skin. This flexible pad can increase the contact area between the tube body and the skin, and has a certain buffering and pressure-reducing effect, and the drainage tube body is relatively fixed on the pad by medical tape or adhesive, so as to avoid direct pressure on the skin by the tube wall.

[0004] However, when the patient turns over, coughs, gets out of bed or changes position due to pain, the external drainage tube is often pulled or twisted and deformed. Since there is a lack of relative rotation freedom between the drainage tube and the flexible pad, the twisting moment generated by the tube body cannot be released, and even if there is a flexible pad under the tube, it is difficult to offset this concentrated pressure, and serious point pressure injury may still occur.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0043] Please refer to Figures 1-5 The specific embodiments provided by the utility model are as follows:

[0044] As Figure 1As shown in the figure, an embodiment of the present invention proposes a drainage tube to prevent pressure injury, which mainly consists of a drainage tube body 1 and a pressure-resistant base 2.

[0045] The drainage tube body 1 includes an intubation tube section 101 and an external tube section 102, which are independent of each other.

[0046] The pressure-resistant base 2 has a through-flow channel 201 formed inside, used to construct a transmission path for the drainage fluid. A first connecting end 202 and a second connecting end 203, corresponding to the internal flow channel 201, are provided on the pressure-resistant base 2, serving as the inlet and outlet interfaces of the flow path, respectively. Furthermore, the pressure-resistant base 2 has a flat or human-curved bottom surface, which serves as the mounting surface in contact with the patient's skin.

[0047] The insertion tube segment 101 is sealed and fixedly connected to the first connection end 202 of the pressure-resistant base 2. This connection method ensures that the insertion tube segment 101 and the pressure-resistant base 2 remain relatively stationary, ensuring that the tube portion inserted into the patient's body is stable and will not pull on the internal tissue of the wound due to shaking at the connection point. It also ensures the sealing of the connection point to prevent leakage of drainage fluid.

[0048] like Figures 2 to 5 As shown, one end of the external tubing segment 102 is connected to the second connecting end 203 of the pressure-resistant base 2 by a sealed rotational connection. That is, the external tubing segment 102 can rotate circumferentially relative to the pressure-resistant base 2. When the external tubing segment 102 is subjected to external torsional or tensile forces, it can eliminate stress through its own rotational movement, thereby avoiding the transmission of torque to the pressure-resistant base 2.

[0049] An adhesive portion 204 is provided on the bottom surface of the pressure-resistant base 2. In use, the pressure-resistant base 2 is adhered and fixed to the skin around the stoma through the adhesive portion 204. The pressure-resistant base 2 is used to bear the weight and tension of the external tubing. In conjunction with the aforementioned rotating connection structure, it effectively reduces the shearing and compressive forces on the skin at the stoma.

[0050] In a preferred embodiment, a hollow ball head 301 is provided at one end of the external tube segment 102 connected to the pressure-resistant base 2. The hollow ball head 301 can be integrally formed at the end of the tube body or it can be an independent component that is assembled and fixed. The interior of the hollow ball head 301 is hollow, and the hollow part is directly and smoothly connected to the internal flow channel of the external tube segment 102, thereby ensuring that the drainage fluid can pass smoothly through the ball head structure.

[0051] Accordingly, a spherical cavity 302 is formed inside the second connecting end 203 of the pressure-resistant base 2. The inner diameter of the spherical cavity 302 is adapted to the outer diameter of the hollow ball head 301.

[0052] In the assembled state, the hollow ball head 301 is accommodated in the spherical cavity 302, and the two constitute a pivotal connection. Based on this, on the one hand, the hollow ball head 301 can rotate 360 degrees around its own axis in the spherical cavity 302, eliminating torsional stress; on the other hand, the hollow ball head 301 can also tilt or swing by a certain angle relative to the spherical cavity 302. This allows the extracorporeal tube segment 102 to flexibly follow the patient's turning over, sitting up and other actions to adjust the lead angle, greatly reducing the lateral overturning moment on the pressure relief base 2 due to the rigidity of the pipeline, thereby ensuring that the bottom surface is always smoothly attached to the skin.

[0053] In a preferred embodiment, the adhesive part 204 includes double-sided tape, hydrocolloid dressing or foam dressing;

[0054] The adhesive part 204 is detachably connected to the bottom surface of the pressure relief base 2 by a magic repeated adhesive layer.

[0055] In a preferred embodiment, the outer surface of the hollow ball head 301 is covered with an elastic sealing layer 303. The elastic sealing layer 303 can be made of medical silicone, thermoplastic polyurethane or other soft polymer materials, and is integrally combined with the hard ball head surface through secondary injection molding or coating process. When the ball head with the elastic sealing layer 303 is installed in the spherical cavity 302, the soft sealing layer will have a slight interference fit with the hard inner wall of the cavity. The elastic material fills the gap between the two parts and forms a reliable liquid barrier.

[0056] Alternatively, an elastic gasket is provided on the inner wall of the spherical cavity 302 in the second connecting end 203. The elastic gasket can be a separate rubber bowl-shaped insert or a soft rubber layer formed on the inner wall of the cavity by two-color injection molding. In this structure, the hard hollow ball head 301 always abuts against the soft elastic gasket when rotating. This not only has the sealing effect described above, but the friction coefficient of the soft material can also provide moderate rotational damping to prevent the extracorporeal tube segment 102 from swinging or sagging due to its own gravity, making the positioning of the pipeline more stable.

[0057] In a preferred embodiment, a sealing sleeve 4 is further included. The sealing sleeve 4 is in the overall structure of a corrugated tube and is made of soft material with good elasticity, such as medical silicone or soft rubber.

[0058] The sealing sleeve 4 is sleeved outside the connection position of the extracorporeal pipe section 102 and the second connection end 203. Specifically, one end of the sealing sleeve 4 is tightly clamped or bonded to the outer wall of the second connection end 203 of the pressure-proof base 2, and the other end is wrapped and fixed to the root position of the extracorporeal pipe section 102 close to the ball head. When the extracorporeal pipe section 102 is angularly deviated, tilted or rotated relative to the pressure-proof base 2, the corrugated sealing sleeve 4 can be freely stretched, compressed or bent, without mechanical interference or obstruction to the flexible movement of the pipe section. It effectively prevents the invasion of external dust, bacteria or foreign matter into the joint to cause jamming or infection, and also plays an auxiliary sealing and beautifying role to prevent internal lubricant from spilling or micro-leakage from polluting the patient's clothes.

[0059] In a preferred embodiment, in order to avoid rigid collision or dead folding of the pipe body with the hard base, an elastic support pad 5 is further provided.

[0060] The elastic support pad 5 is arranged on the top surface of the pressure-proof base 2, and specifically located directly below the connection position of the extracorporeal pipe section 102 and the second connection end 203. The elastic support can be integrally formed with the pressure-proof base 2 body by two-color injection molding or encapsulation process, so as to obtain good bonding strength; or it can be a separate soft rubber part or a silicone block, which is fixed on the surface of the pressure-proof base 2 by the back glue on the bottom.

[0061] In actual use, when the extracorporeal pipe section 102 is deviated downward, the elastic support can flexibly support the drooping pipe body, avoiding direct impact of the pipe wall on the surface of the hard pressure-proof base 2, and more importantly, providing a support point with a certain height for the root of the pipe, preventing the pipe body from forming an excessively sharp corner at the connection root, so as to ensure that the drainage channel is always unobstructed.

[0062] In a preferred embodiment, a plurality of air-permeable flow guide grooves 6 extending to the edge of the base are reserved on the skin-adhesive surface of the adhesive part 204. These air-permeable flow guide grooves 6 form air flow channels between the skin surface and the external environment.

[0063] Among them, the air-permeable flow guide grooves 6 can be radially distributed, that is, the center (or stoma position) of the pressure-proof base 2 as the origin, extending to the periphery in a divergent manner, which is conducive to quickly guiding the sweat or exudate accumulated in the center to the periphery of the base for discharge; or the air-permeable flow guide grooves 6 can be distributed in a grid shape, forming a longitudinal and transverse air exhaust network to ensure that any area under the adhesive part 204 has good air permeability.

[0064] When the pressure-protecting base 2 is pasted on the skin of a patient for a long time, the sweat and micro-amount of exudate secreted by the skin surface can be discharged along the flow grooves in time without being sealed under the adhesive layer, and meanwhile, fresh air from outside can enter the pasting area through the grooves to keep the skin surface dry. This not only effectively reduces the probability of skin allergy, eczema or immersion injury, but also helps to maintain the long-lasting adhesion of the adhesive and prevent the base from being loosened due to moisture.

[0065] In a preferred embodiment, the pressure-protecting base 2 is composed of a hard framework layer for maintaining shape and a soft buffer layer coated outside the hard framework layer.

[0066] The hard framework layer constitutes the internal core support structure of the pressure-protecting base 2 and is usually made of polypropylene, polycarbonate or other hard plastic with high mechanical strength. The main function of the hard framework layer is to provide a shaped support for the flow channel 201 to prevent the channel from being deformed under pressure, and to provide an anchoring base for the first connecting end 202 and the second connecting end 203 to ensure the reliability of the rotating or fixed connection.

[0067] The soft buffer layer is made of medical-grade silicone, thermoplastic elastomer or other low-hardness soft glue material. The soft buffer layer is tightly coated on the outer surface of the hard framework layer through two-color injection molding or secondary encapsulation process, especially covering the edges and bottom area of the base. Therefore, the bottom surface of the pressure-protecting base 2 for pasting on the skin is actually formed by the soft buffer layer.

[0068] The utility model also provides a drainage tube assembly, it includes:

[0069] The pressure-protecting drainage tube as claimed in any one of the above embodiments;

[0070] A drainage container, which is in communication with the one end of the extracorporeal tube segment 102 of the pressure-protecting drainage tube away from the pressure-protecting base 2;

[0071] The drainage container is one of a drainage bag, a negative pressure drainage bottle or a metering urine bag.

[0072] In this embodiment, it has all the beneficial effects described above, which will not be repeated here.

[0073] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and deformations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
