Description

Technical Field

[0001] The present invention relates to the technical field of cardiothoracic surgery, and in particular to a lung protection device. Background Art

[0002] After cardiothoracic surgery, patients' chests often require special care and protection to promote wound healing, prevent complications, and relieve pain. Traditional care methods often include using simple chest straps or bandages to immobilize the chest, however, these methods have many limitations.

[0003] First, traditional chest straps or bandages cannot be individually adjusted to the patient's specific chest contours, making it difficult to closely fit the patient's rib cage. This not only causes discomfort and pressure when worn, but also may affect the fixation effect and reduce the quality of care.

[0004] Secondly, postoperative patients often require respiratory function training to prevent lung complications such as atelectasis and pneumonia. However, traditional nursing devices lack the function of assisting respiratory training, and patients need to use respiratory training devices, which increases the complexity and inconvenience of nursing care.

[0005] In addition, postoperative patients may also need local medication or hot compress therapy to relieve pain, promote blood circulation and wound healing. Traditional nursing devices cannot integrate these auxiliary treatment functions, and patients need to use different devices separately, which increases the complexity and cost of nursing.

[0006] In response to the above problems, it is urgently necessary to carry out innovative designs based on the original lung protection devices. Summary of the Invention

[0007] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too single, and provides a lung protection device that is significantly different from the existing technology to solve the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a lung protection device comprising a base plate, the bottom of which is connected to an elastic plate. The elastic plate is made of an elastic material and is configured in an arcuate structure to better conform to the natural curve of the human thorax. The base plate and the elastic plate together form an I-shaped structure, which not only ensures the overall stability of the device but also provides sufficient operating space for adjusting the structure. A number of straps are symmetrically connected to both sides of the elastic plate to secure the device to the patient and ensure its stability during use.

[0009] Preferably, an adjustment structure is connected to the top of the base plate, which is used to control the bending curvature of the side of the elastic plate to adapt to the chest shape of different patients. The adjustment structure includes a cylinder, a screw, a groove, a piston rod, a trachea and a two-way air pump. Four cylinders are provided at equal angles on the top of the base plate, and each cylinder is rotatably connected to the base plate. A screw is threadedly connected in each cylinder, and a groove is provided at the lower end of the screw, and a piston rod is provided in the groove, and the lower end of the piston rod is rotatably connected to the elastic plate. The outer wall of each screw is provided with a trachea, which is connected to the groove inside it, and all trachea are connected to a two-way air pump. By squeezing the two-way air pump, air can be inflated into the groove, thereby changing the position of the piston rod in the groove, thereby achieving precise adjustment of the bending curvature of the side of the elastic plate.

[0010] Preferably, to achieve synchronous rotation of the multiple cylinders, a chain is connected between the cylinders on the base plate near the curved side of the elastic plate. The end of the piston rod is configured as a polygonal structure, and the inner wall of the groove is configured as a corresponding polygonal structure, so that the piston rod and the groove can be engaged in a snap-fit ​​sliding connection. This design not only ensures stable movement of the piston rod within the groove, but also facilitates adjustment operation.

[0011] Preferably, a mounting groove is provided at the bottom of the elastic plate, and the mounting groove can be used to fill medicine and place a heating plate so as to provide local treatment or warming to the patient when needed.

[0012] Preferably, the straps include a fastener and an airbag belt. Each strap end is connected to a fastener, which can be configured as a snap-on buckle or Velcro structure to quickly secure and position the straps, facilitating operation by medical personnel. Furthermore, each strap is provided with an airbag belt near the elastic plate. The airbag belt can be adjusted in inflation based on the patient's body shape and comfort requirements to ensure stability and comfort during wear.

[0013] Compared with existing technologies, the present invention offers the following advantages: the lung protector can be individually adjusted to the specific contours of the patient's chest, closely fitting the shape of the thorax, providing a more fitted and comfortable support experience, and reducing the discomfort and pressure caused by a poor fit. This personalized adaptation ensures comfort and stability during wear.

[0014] Secondly, the device is equipped with a bidirectional air pump that periodically delivers and withdraws air from the groove, simulating breathing movements. This helps patients practice deep breathing, promotes lung expansion and contraction, and effectively prevents pulmonary complications such as atelectasis and pneumonia. This function plays a crucial role in assisting recovery for postoperative patients or those with weak respiratory function, helping to accelerate their recovery.

[0015] Furthermore, the mounting slots at the bottom of the elastic plate can be filled with therapeutic agents or placed with a heating pad, depending on the patient's needs. This allows for a synergistic combination of physical support, respiratory assistance, medication, and heat therapy. For example, filling with therapeutic agents can deliver localized therapeutic effects, relieving pain and promoting blood circulation, while placing a heating pad can provide a warm compress to relieve muscle tension.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The present invention provides a technical solution: a lung protection device, comprising a base plate 1, an elastic plate 2, an adjustment structure 3, a strap 4, a fixer 401, an airbag belt 402, and a mounting groove 5. The bottom of the base plate 1 is connected to the elastic plate 2, and the top of the base plate 1 is connected to the adjustment structure 3, which is used to control the curvature of the side of the elastic plate 2 to better fit the chest shape of different patients. A number of straps 4 are symmetrically connected to both sides of the elastic plate 2 for fixing the device to the patient. A mounting groove 5 is also provided at the bottom of the elastic plate 2, which can be used to load medicine and place a heating plate so as to provide local treatment or warming to the patient when needed.

[0023] The elastic plate 2 is designed as an arc-shaped structure and is made of an elastic material to ensure that it can adapt to the natural curve of the patient's thorax and has a certain degree of deformation. The base plate 1 and the elastic plate 2 together form an "I"-shaped structure, which not only ensures the overall stability of the device but also provides sufficient operating space for the adjustment structure 3.

[0024] The adjustment structure 3 is one of the key components of this device, which specifically includes a cylinder 301, a screw 302, a groove 303, a piston rod 304, an air pipe 305 and a two-way air pump 306. Four cylinders 301 are provided at equal angles on the top of the base plate 1, and each cylinder 301 is rotatably connected to the base plate 1. A screw 302 is threadedly connected in each cylinder 301, and a groove 303 is provided at the lower end of the screw 302. A piston rod 304 is then provided in the groove 303, and the lower end of the piston rod 304 is rotatably connected to the elastic plate 2. In addition, the outer wall of each screw 302 is provided with an air pipe 305, which is connected to the groove 303 inside it, and all air pipes 305 are connected to a two-way air pump 306. By pinching the two-way air pump 306, air can be inflated in the groove 303, thereby changing the position of the piston rod 304 in the groove 303, and then realizing precise adjustment of the curvature of the side of the elastic plate 2.

[0025] To achieve synchronous rotation of the multiple cylinders 301, chains are connected between the cylinders 301 on the curved side of the base plate 1 near the elastic plate 2. The end of the piston rod 304 is designed with a polygonal structure, and the inner wall of the groove 303 is provided with a corresponding polygonal structure, so that the piston rod 304 and the groove 303 can be connected in a snap-fit ​​sliding connection. This design ensures stable movement of the piston rod 304 within the groove 303 and facilitates adjustment operation.

[0026] The strap 4 is a key component for securing the device to the patient and includes a fastener 401 and an airbag strap 402. Each strap 4 is connected to a fastener 401 at its end. The fastener 401 can be configured as a snap-on buckle or Velcro structure, allowing for quick fastening and positioning of the strap 4, facilitating operation by medical personnel. Furthermore, each strap 4 is provided with an airbag strap 402 on the side near the elastic plate 2. The airbag strap 402 can be adjusted to the patient's body shape and comfort requirements to ensure stability and comfort during wear.

[0027] Working principle: According to Figure 1As shown, first, according to the contour of the patient's chest, the cylinders 301 on both sides are rotated, and the other cylinder 301 on the same side is driven to rotate synchronously by a chain. As the cylinder 301 rotates, the screw 302 connected to the inner thread of the cylinder 301 is moved downward out of the cylinder 301 under the auxiliary limit of the piston rod 304. The screw 302 and the piston rod 304 push the side of the elastic plate 2 to bend to adapt to the contour of the patient's chest. Then, the strap 4 is wrapped around the patient's chest and fixed by the fixator 401. The airbag belt 402 is used to better fit the patient's body and reduce the sense of oppression.

[0028] The bidirectional air pump 306 is activated to periodically deliver and extract air into the groove 303 through the trachea 305 to help the patient perform deep breathing training and prevent lung complications;

[0029] The installation slot 5 can be filled with therapeutic agents or heating plates according to the patient's needs for auxiliary treatment. This is the working principle of the lung protection device.

[0030] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
