Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically to scenarios in which a large open wound on the human chest is quickly treated and first aid is provided, such as the rapid treatment of a chest wound caused by a battlefield blast injury or the treatment of similar injuries in production and life scenarios. More specifically, it provides a chest wound blocking channel system. Background Art

[0002] In modern medicine, with the rapid advancement of science and technology, significant progress has been made in the technologies and medical devices used to rapidly and urgently manage various traumatic injuries. From trauma ambulances and portable monitoring equipment to advanced diagnostic imaging tools, medical professionals now have more resources to respond to various emergencies. However, while these advances have greatly improved treatment efficiency and survival rates, significant technical and methodological gaps remain in the management of specific types of injuries, particularly large open chest wounds.

[0003] The chest is home to vital organs, including the heart, lungs, and other critical organs. Severe open injuries to this area, particularly in settings lacking specialized medical support and equipment (such as battlefields or major industrial accidents), significantly reduce the patient's chances of survival. These injuries are often accompanied by life-threatening complications such as massive bleeding, pneumothorax, and even cardiac tamponade, requiring medical personnel to quickly and effectively stop bleeding, seal the wound, and stabilize the patient's vital signs.

[0004] Currently, although some emergency medical equipment such as temporary tourniquets and closed chest drainage devices are available, these devices are often inadequate for treating large open chest wounds. These devices may not provide sufficient coverage to control bleeding, or may require a relatively long time to operate, which can be fatal in emergency situations. In addition, the use of these devices usually requires a certain level of expertise and skills, which is often difficult to meet in frontline or non-professional rescue environments.

[0005] Therefore, it is particularly urgent to develop a rapid treatment system specifically for large-scale open chest wounds. Utility Model Content

[0006] Therefore, the purpose of the present invention is to solve the problem of rapid treatment and first aid in the case of large-scale open chest wounds, and to provide a chest wound sealing channel system.

[0007] The technical solution of the utility model is a chest wound blocking channel system, comprising:

[0008] A closed channel, with a flexible support wrapped on the outer wall and an elastic balloon inside, forming a balloon lumen inside the balloon, and the balloon is connected to a fluid-filled pipe and a connector;

[0009] a sealing cap, which is detachable and sealed at one end of the balloon, and has an elastic circular hole for the passage of surgical instruments, a circular hole plug for blocking the elastic circular hole, a drainage connector, and a suction connector;

[0010] The dual-purpose drainage ball has a fluid space inside, which also serves as a drainage space. It has a medical Luer connector that is unidirectionally connected to the pipeline and connector, and a drainage pipeline and a trumpet connector that are unidirectionally connected to the drainage connector or the suction connector. The bottom of the dual-purpose drainage ball has a liquid discharge valve.

[0011] According to the technical solution of the present invention, the balloon is made of a double-layer elastic membrane material, and the flexible support body wrapped by the outer wall is a foam sponge.

[0012] According to the technical solution of the present invention, one end of the balloon is connected to an elastic annular inner snap ring, and the other end is connected to an elastic annular outer snap ring, and the sealing cap is snap-connected to the elastic annular outer snap ring.

[0013] According to the technical solution of the present invention, the cross section of the elastic annular outer clamping ring is in the shape of "∞"; the sealing cap has an assembly structure adapted to the cross section of the elastic annular outer clamping ring.

[0014] According to the technical solution of the present invention, the fluid space of the dual-purpose drainage ball is pre-filled with fluid or left empty for filling the balloon with fluid.

[0015] According to the technical solution of the present invention, the medical Luer connector is provided with a duckbill-shaped one-way valve 1, the dual-purpose drainage ball is provided with a duckbill-shaped one-way valve 2, and the suction connector and the drainage connector are both provided with a duckbill-shaped one-way valve 3. The one-way direction of the duckbill-shaped one-way valve 1 is to flow out from the inside of the dual-purpose drainage ball to the outside, the one-way direction of the duckbill-shaped one-way valve 2 is to flow into the dual-purpose drainage ball from the outside, and the one-way direction of the duckbill-shaped one-way valve 3 is to flow out from the inner cavity of the balloon.

[0016] According to the technical solution of the present invention, the inner side of the sealing cap is provided with an inner drainage tube connected to the drainage joint, and the inner side of the sealing cap is provided with an air drainage tube connected to the suction joint.

[0017] The technical solution of the utility model also includes a foaming sponge block.

[0018] It can be seen from the above technical solution that compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model can realize emergency treatment in special scenarios of large-scale open chest wounds:

[0020] 1. Rapid and effective wound closure to prevent secondary contamination:

[0021] The utility model quickly fills the inner cavity of the balloon with fluid (such as physiological saline or air), installs the sealing cap on the outer clamping ring of the blocking channel, and puts it into the wound, evaluates the size and shape of the wound, and can use a foam sponge block to fill it when the shape is irregular. The inner clamping ring of the blocking channel is placed in the wound, and the Luer connector of the dual-purpose drainage ball is connected to the balloon pipeline connector at the same time. The dual-purpose drainage ball is squeezed to allow the liquid or air inside it to enter the balloon on the blocking channel, so that the balloon expands. The expanded balloon squeezes the foam sponge wrapped outside the balloon to cause it to deform and compress and seal the edge of the wound. The balloon continues to expand, which can achieve compression hemostasis and firm sealing of the wound.

[0022] The closed channel design ensures a sterile environment during emergency wound treatment, preventing the intrusion of external bacteria and reducing the risk of infection. Furthermore, the elastic circular hole in the sealing cap allows surgical instruments to pass through. The elastic circular hole can be sealed with a circular hole plug before and after the surgical instruments are inserted and removed, further isolating the source of contamination.

[0023] The use of a flexible support body not only increases the stability of the closed channel, but also helps to restore the normal shape of the chest wall and reduce complications such as dyspnea caused by chest wall collapse.

[0024] 2. One-way flow control, efficient drainage system:

[0025] The design of the dual-purpose drainage ball integrates drainage space and fluid storage. It can not only collect fluid in the pleural cavity, but also maintain the expansion state of the balloon by filling it with fluid, thus achieving the dual functions of drainage and sealing.

[0026] The application of medical Luer connector and duckbill one-way valve ensures that the fluid can only flow in one direction, that is, flowing out or in from the inside of the dual-purpose drainage ball, and flowing out from the inner cavity of the balloon, effectively preventing backflow and ensuring the effectiveness and safety of the drainage system.

[0027] The design of the drainage tubing and liquid discharge valve allows medical staff to easily control and manage the drainage process, reducing the risk of infection.

[0028] 3. Convenient operation and assembly

[0029] The present utility model adopts a modular design concept, and the closed channel and the sealing cap can be quickly assembled and disassembled through a simple snap connection, which is convenient for rapid on-site deployment and use. The adaptive design of the elastic annular outer clamp and the closing cap enables the present utility model to adapt to chest wounds of different sizes and shapes, improving its versatility and practicality. The use of foam sponge blocks and flexible support bodies not only reduces the overall weight, but also facilitates folding and compression, making it convenient to carry and store. The above structure can be used without a certain degree of professional knowledge and skilled personnel, and is suitable for use in front-line or non-professional rescue environments. At the same time, even under the most severe conditions, medical staff can seize that ray of hope and provide timely and effective treatment to the injured, thereby saving more lives.

[0030] 4. Improve the success rate of treatment

[0031] This new device integrates sealing and drainage functions, providing a comprehensive solution for treating large, open chest wounds and significantly improving the success rate of treatment. Through effective hemostasis, sealing, and drainage, it significantly reduces the risk of death from complications such as excessive bleeding and infection. In an emergency, every second counts. The device's rapid response and high efficiency buy the injured precious time to survive and pave the way for subsequent professional medical treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] Although some emergency medical devices, such as temporary tourniquets and closed chest drainage devices, are currently available, they are often inadequate for treating large open chest wounds. These devices may not provide sufficient coverage to control bleeding, or may require a relatively long time to operate, which can be fatal in emergency situations. Furthermore, the use of these devices typically requires a certain level of expertise and skills, which is often difficult to meet on the front lines or in non-professional rescue environments.

[0041] Based on the problems existing in the prior art, the present invention can significantly reduce the probability of survival when a large open chest wound occurs in the human body without the support of professional environmental conditions, equipment and consumables. Depending on the degree of trauma, medical staff should always have a chance to save more lives through special medical equipment systems.

[0042] Such a system should possess at least the following characteristics: easy to carry and use, allowing for rapid deployment even in the absence of specialized medical facilities; effective control of extensive bleeding and provision of temporary chest closure; and flexibility to accommodate wounds of varying sizes and shapes. With such a system, even in the most adverse conditions, medical personnel can seize the glimmer of hope, provide timely and effective treatment, and ultimately save more lives.

[0043] In view of this, the present invention provides a chest wound blocking channel system, see attached Figure 1 and 2, at least includes: a closed channel 1, a sealing cap 2 and a dual-purpose drainage ball 3; a flexible support body is wrapped around the outer wall of the closed channel 1, and an elastic balloon 14 is provided inside the closed channel 1, and a balloon inner cavity 15 is formed inside the balloon 14. The balloon inner cavity 15 corresponding to the balloon 14 is connected to a fluid-filled pipeline and a joint 16 to expand the balloon 14; the inner layer of the balloon 14 is an operating channel 17, which allows various surgical instruments 5 to pass through. The sealing cap 2 is detachable and sealed at one end of the balloon 14, and is provided with an elastic circular hole 21 for the surgical instrument 5 to pass through, a circular hole plug 22 for blocking the elastic circular hole 21, a drainage joint 23 and a suction joint 24; the circular hole plug 22 is connected to the sealing cap 2 and is movable. It can be inserted into the elastic circular hole 21 to block it, and can also be removed to make it unobstructed. The dual-purpose drainage ball 3 has a fluid space inside, which also serves as a drainage space. It has a medical Luer connector 32 that is unidirectionally connected to the tubing and connector 16. It also has a drainage tubing and a horn connector 33 that are unidirectionally connected to the drainage connector 23 and the suction connector 24. A liquid discharge valve 34 is located at the bottom of the dual-purpose drainage ball 3. The medical Luer connector 32 is interconnected with the tubing and connector 16.

[0044] See attached Figure 2 and 3 In the embodiment of the present invention, the balloon 14 is made of a double-layer elastic membrane material, and the flexible support body wrapped around its outer wall is a foam sponge 11. The foam sponge 11 should be made of elastic medical polyurethane and should have high resilience and airtightness. The foam sponge is placed on the outside of the balloon to block the channel, protecting the balloon on one side and contacting the wound edge on the other side.

[0045] The channel blocking balloon should be made of a high-pressure resistant film material with elasticity. The space between the two layers of film material constitutes the balloon. The joint connected to the outer wall of the balloon relative to the inside of the blocking channel should be composed of a soft pipe and a medical standard one-way valve joint.

[0046] In one embodiment of the present invention, see the attached Figure 2 One end of the balloon 14 is connected to an elastic annular inner snap ring 12, which is inserted into the wound, and the other end is connected to an elastic annular outer snap ring 13, and the sealing cap 2 is snap-fitted to the elastic annular outer snap ring 13.

[0047] The elastic annular inner clasp 12 and the elastic annular outer clasp 13 should be made of a medical polyurethane material having elasticity and good support. The two clasps should be tightly connected to the balloon.

[0048] The elastic annular outer retaining ring 13 should be matched with the sealing cap, can be assembled and disassembled, and its cross-section is "∞"-shaped; the sealing cap 2 has an assembly structure 27 that is adapted to the cross-section of the elastic annular outer retaining ring 13, so that the sealing cap can be firmly assembled on the elastic annular outer retaining ring 13.

[0049] In addition, the size of the elastic circular hole on the sealing cap 2 should allow the most basic laparoscopic surgical instruments or smaller-sized medical instruments to pass through.

[0050] In the present invention, the fluid space of the dual-purpose drainage ball 3 is pre-filled with fluid or left empty for filling the balloon 14. The fluid may be physiological saline or gas.

[0051] In the embodiment of the present utility model, see the attached Figure 3 The drainage line and the horn connector 33 can be connected to the drainage connector 23 or the suction connector 24. The suction connector 24 and the drainage connector 23 on the sealing cap 2 are equipped with duckbill-shaped one-way valves. The one-way valves only allow gas and liquid to pass through in one direction. One-way means that gas and liquid are only allowed to flow out of the human body.

[0052] The dual-purpose drainage ball 3, which is supplied in at least one unit, has a medical Luer connector that allows only one direction of gas and liquid flow. This unidirectional function is achieved by a duckbill-shaped one-way valve inside the ball. The drainage tubing and trumpet-shaped connector on the dual-purpose drainage ball allow only one direction of gas and liquid flow. This unidirectional function is achieved by a duckbill-shaped one-way valve inside the ball.

[0053] For details, see the attached Figure 4 and 5 The medical Luer connector 32 has a duckbill-shaped one-way valve 321, the dual-purpose drainage ball 3 has a duckbill-shaped one-way valve 351, and the suction connector 24 and the drainage connector 23 both have a duckbill-shaped one-way valve 3 241. The one-way direction of the duckbill-shaped one-way valve 321 is to flow out from the inside of the dual-purpose drainage ball 3 to the outside, the one-way direction of the duckbill-shaped one-way valve 351 is to flow into the dual-purpose drainage ball 3 from the outside, and the one-way direction of the duckbill-shaped one-way valve 3 241 is to flow out from the balloon lumen 15.

[0054] See attached Figure 3Specifically, the drainage connector 23 has a one-way gas-liquid passage function and passes through the sealing cap body. The side of the sealing cap facing the human body is connected to an internal drainage tube 26 for liquid drainage. The sealing cap also has a suction connector 24. The side of the sealing cap facing the human body is connected to an air duct 25 for extracting gas. This air duct 25 has a one-way gas-liquid passage function and passes through the sealing cap body.

[0055] See attached Figure 6 , further comprising a foam sponge block 4 having a rectangular cross-section. The foam sponge block 4 comprises a plurality of independent blocks, and can be in the form of sheets, strips, or other shapes. The number of foam sponge blocks 4 is at least one, and their shape is not limited to the strip shape shown in the schematic diagram; other simple shapes that can be achieved by industrial methods, such as sheet-like blocks, can also be used.

[0056] A chest wound sealing system should include at least: a balloon channel, a sealing cap, a dual-purpose drainage ball, and a foam sponge block.

[0057] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0058] See also Figure 6 The utility model can realize emergency treatment in the special scenario of large-sized open chest wounds. The sealing cap is installed on the elastic annular outer clamping ring of the blocking channel and placed in the wound (Z in the figure indicates human tissue). The size and shape of the wound are evaluated. When the shape is irregular, a foam sponge block can be used to fill it. The inner clamping ring of the blocking channel is placed in the wound. At the same time, the medical Luer connector of the dual-purpose drainage ball is connected to the balloon pipeline connector. The dual-purpose drainage ball is squeezed to allow the liquid or air inside it to enter the balloon on the blocking channel, so that the balloon expands. The expanded balloon will squeeze the foam sponge wrapped outside it to deform and compress and seal it at the edge of the wound. Continuing to expand the balloon can achieve compression hemostasis and firm sealing of the wound.

[0059] After completion, the dual-use drainage ball can be removed for future use, and the remaining liquid in the dual-use drainage ball can be discharged through the liquid discharge valve at the bottom of the dual-use drainage ball. At this time, use the negative pressure drainage pipeline and trumpet-shaped connector on the dual-use drainage ball to connect to the suction connector on the sealing cap. Press the dual-use drainage ball to aspirate the gas inside the chest cavity. If it is connected to the drainage connector of the sealing cap, pressing the dual-use drainage ball can aspirate the liquid inside the chest cavity. The aspirated liquid will be stored in the dual-use drainage ball. When the liquid is full, it can be discharged through the liquid discharge valve at the bottom of the dual-use drainage ball. The above operation can be repeated.

[0060] The elastic hole in the sealing cap should be sealed with a hole plug. When the hole plug is removed, air will enter the chest cavity through the hole. In this case, the laparoscopic instrument should be quickly inserted into the elastic hole for operation. While operating, continue to use the dual-purpose drainage ball to aspirate air or fluid. After the operation is completed, the laparoscopic instrument should be withdrawn and the elastic hole should be quickly sealed with the hole plug.

[0061] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0062] See attached Figure 3 In the illustrated state, 311 in the figure can be a preset physiological saline solution, and the dual-purpose drainage ball 3 has been connected to the connector 16 of the balloon pipeline. The liquid inside it can be filled into the balloon 14 through the one-way structure shown in the figure to make it expand; the medical Luer connector 32 on the dual-purpose drainage ball 3 realizes one-way passage of gas and liquid through the duckbill-shaped one-way valve 321 inside, and this one-way flow is from the inside of the dual-purpose drainage ball to the outside; the drainage pipeline and the trumpet-shaped connector 33 on the dual-purpose drainage ball 3 realize one-way passage of gas and liquid through the duckbill-shaped one-way valve 351 inside the dual-purpose drainage ball, and this one-way flow is from the outside to the inside of the drainage ball.

[0063] In the embodiment of the utility model, the above-mentioned sealing cap 2 has been assembled with the above-mentioned elastic annular outer retaining ring 13; the drainage joint 23 and the suction joint 24 on the sealing cap both realize one-way passage of gas and liquid through the duckbill-shaped one-way valve 241, and this one-way flow is from the blocked channel to the outside of the human body.

[0064] See attached Figure 6In the illustrated state, the present invention is applied to a wound, with the balloon 14 already inflated and supporting the foam sponge 11 to press against the edge of the human tissue Z. Relative to the lower portion of the schematic diagram of the present system application, the space between the human tissue Z and the blocked channel is filled with a foam sponge block 4. The round hole plug 22 on the sealing cap has been removed from the elastic round hole 21 and a laparoscopic surgical instrument has been passed through it. The drainage pipe and trumpet-shaped connector 33 on the dual-purpose drainage ball have been connected to the drainage connector 23 on the sealing cap, and the accumulated fluid in the blocked channel and inside the human body can be drained into the dual-purpose drainage ball through the inner 26. When the liquid volume in the dual-purpose drainage ball is full, the liquid discharge valve 34 can be opened for discharge. The drainage pipe and trumpet-shaped connector 33 on the dual-purpose drainage ball can also be connected to the suction connector 24 on the sealing cap, and the gas in the blocked channel and inside the human body can be drained into the dual-purpose drainage ball through the air duct 25.
