Description

Technical Field

[0001] This utility model relates to the field of medical orthopedic devices, and in particular to a personalized pectus excavatum correction device. Background Technology

[0002] Pectus excavatum is a deformity of the thoracic skeleton, generally referring to the sternum, costal cartilage, and part of the ribs concave dorsally, forming a funnel shape. Pectus excavatum can compress organs within the thoracic cavity, such as the heart and lungs, restricting cardiopulmonary function during activity. Currently, patients with pectus excavatum are generally corrected using a negative pressure suction device. These devices are mostly made of flexible materials such as medical-grade rubber or silicone. A negative pressure is created through an air suction device, and patients gradually correct the deformity by wearing the device daily for an extended period. Typically, the device is worn for 1-2 hours daily, and the entire treatment cycle can last 1-2 years.

[0003] Existing orthodontic devices typically achieve negative pressure through manual suction, which can lead to unstable negative pressure levels and negatively impact treatment effectiveness. Furthermore, due to varying patient body shapes, standard suction cup orthodontic devices on the market suffer from poor fit; the suction cups struggle to accurately cover the areas requiring treatment, and wearing oversized devices can increase the burden on patients and cause significant inconvenience to their daily lives.

[0004] CN218528998U discloses an intelligent pectus excavatum negative pressure suction cup, including a base, a mounting cover on the base, the inner wall of the mounting cover and the inner wall of the base forming a negative pressure cavity, a mounting shell on the mounting cover, and a vacuum device detachably connected to the mounting shell; the mounting shell is equipped with a controller and a display electrically connected to the controller, the controller is equipped with a height detection module and a data storage and processing module, a piston is movably connected to the mounting shell, one end of the piston moves within the negative pressure cavity and is equipped with a distance sensing device, when the distance sensing device contacts the patient's chest and moves, the distance sensing device converts the displacement of the piston into an electrical signal through the height detection module and outputs it to the display.

[0005] The negative pressure suction cup in this patent document requires manual squeezing of the airbag to create the negative pressure required for treatment within the negative pressure chamber. On the one hand, a long hose needs to be connected to the airbag, which increases the complexity of the device; on the other hand, the negative pressure control method of manually squeezing the airbag is not precise and may not achieve the best negative pressure treatment effect.

[0006] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

[0007] In view of the shortcomings of the prior art, this application proposes a personalized pectus excavatum correction device, which aims to solve one or more technical problems in the prior art.

[0008] This utility model relates to a personalized pectus excavatum correction device, which includes a suction cup cover, the upper surface of which forms a base. A control box and an air pump are disposed inside the base. The control box has an end face corresponding to the air pump, so that the air pump can be inserted into the control box through the end face. The control box is detachably connected to an air tube. One end of the air tube away from the control box is connected to a first mounting hole that passes through the upper surface of the suction cup cover, and the other end passes through a second mounting hole on the surface of the control box to connect to the air pump. When the control box is placed inside the base, an adjustment member provided on the side of the control box provides the fastening force required for the installation of the control box by abutting against the base.

[0009] The suction cup cover of this invention features a personalized design, successfully solving the problem that standard suction cup products cannot adapt to patients of different body types. Using existing 3D scanning or 3D photography technology, three-dimensional data of the true shape of each patient's chest can be obtained. Based on this data, the suction cup cover of this invention can be designed to conform to the patient's actual body shape, effectively covering the area requiring treatment while reducing unnecessary space occupation, thereby improving patient comfort. Furthermore, the concave base of the suction cup cover effectively integrates the control box and air pump, improving the space utilization of the entire device, reducing the external structural volume, and ensuring a tight connection between components. The end-face connection design between the control box and the air pump simplifies the component installation process, improves disassembly, and makes maintenance and replacement of components (such as batteries) more convenient. In addition, the adjustable part allows the control box to be secured by abutting against the side wall of the base when it is inside the base, ensuring a stable installation of the control box and preventing loosening or displacement of components during use. This design enhances the stability of the device, ensuring a stable working state during treatment.

[0010] According to a preferred embodiment, the adjusting member includes a head and an insertion portion, wherein the peripheral surface of the insertion portion has an external thread corresponding to an internal thread disposed on the side of the control box, so that the adjusting member can rotate to adjust the distance between its head and the control box, thereby changing the contact force between the adjusting member and the base. The adjusting member can adjust its head position through a simple rotational operation, eliminating the need for medical personnel to use complex tools or perform cumbersome operations during installation and maintenance, thus improving the convenience of the device and the patient experience. The adjusted stability effectively prevents the control box from loosening or shifting during use, thereby ensuring that the device maintains good performance during operation.

[0011] According to a preferred embodiment, the air pump includes a mounting base and a motor connected to the mounting base. The motor is electrically connected to a control box. The mounting base partially seals the end face of the control box with a pre-reserved gap. The mounting base is equipped with an air inlet and an air outlet. An air pipe is detachably connected to the air inlet, and the air outlet communicates with the outside atmosphere through the gap. The configuration of the air inlet and outlet further enhances the functionality of the air pump. The detachable connection between the air inlet and the air pipe allows the air pump to be easily connected to a negative pressure chamber, facilitating pressure regulation within the negative pressure chamber. The air outlet's communication with the outside atmosphere through the pre-reserved gap ensures smooth release of the gas discharged from the air pump, preventing pressure abnormalities caused by gas accumulation and improving safety.

[0012] According to a preferred embodiment, a one-way valve is fitted onto one end of the air tube that connects to the first mounting hole on the upper surface of the suction cup cover. The diameter of the one-way valve matches the inner diameter of the first mounting hole, allowing the air tube to maintain an airtight connection with the suction cup cover via the one-way valve. The one-way valve design allows gas to flow from the negative pressure chamber to the air pump while effectively preventing reverse gas flow. This feature ensures an airtight connection between the air tube and the suction cup cover, helping to maintain pressure stability in the negative pressure chamber, thereby improving the device's operating efficiency. Furthermore, the matching diameter of the one-way valve with the inner diameter of the first mounting hole ensures a tight connection and unobstructed fluid passage. This matching design reduces eddies and resistance that may be generated when the airflow passes through the connection point, optimizes the airflow path, and improves the overall performance of the air pump.

[0013] According to a preferred embodiment, the suction cup cover is detachably connected to a suction cup skirt. The top surface of the suction cup skirt has a corresponding engagement groove surrounding the suction cup cover, allowing the suction cup cover to be inserted into the engagement groove along with the suction cup skirt to jointly enclose a negative pressure cavity. This plug-in connection provides convenient disassembly and installation, enabling medical personnel to perform maintenance or component replacement quickly and easily. Furthermore, the design of the suction cup skirt corresponds to the size of the suction cup cover, ensuring a tight fit between the two, thereby effectively enclosing a negative pressure cavity for the treatment of pectus excavatum.

[0014] According to a preferred embodiment, the control box is equipped with a pressure sensor and a buzzer. An opening is provided in the base corresponding to the pressure sensor, allowing the pressure-sensitive element of the pressure sensor to be placed inside the negative pressure chamber. This placement of the pressure-sensitive element enables the pressure sensor to monitor changes in the negative pressure chamber in real time, helping medical staff to take timely measures based on the pressure, thus ensuring the patient's treatment effectiveness.

[0015] According to a preferred embodiment, the surface of the control box is equipped with a display screen electrically connected to the pressure sensor. The display screen can show the negative pressure data monitored by the pressure sensor in real time. This allows medical personnel to intuitively understand the pressure status within the negative pressure chamber, thus providing a basis for timely adjustments to the equipment.

[0016] According to a preferred embodiment, the surface of the control box is equipped with several buttons, which are electrically connected to the motor and buzzer inside the control box. The button design allows medical personnel to directly operate the equipment and conveniently control the working status of the motor and buzzer. Users can quickly adjust the equipment's operating parameters, such as starting or stopping the air pump and setting a timer for the buzzer, through simple pressing operations, improving operational convenience.

[0017] According to a preferred embodiment, the buttons and display screen are arranged at both ends of the control box surface with a spacing, such that the trachea connecting the first mounting hole and the second mounting hole passes over the gap between them without obstructing the buttons and display screen. By arranging the buttons and display screen at a reasonable interval, medical staff can conveniently press the buttons or view the displayed information when operating the equipment without being disturbed by the trachea. This reduces the risk of misoperation and improves the operating experience for medical staff.

[0018] According to a preferred embodiment, a flange is provided on the circumferential sidewall of the suction cup skirt, and the bottom surface of the flange is recessed towards the top surface to form a lifting groove. Medical personnel can apply an upward lifting force to the suction cup skirt by inserting their fingers into the lifting groove, thereby effectively prying open a corner of the suction cup skirt, eliminating the negative pressure environment in the negative pressure chamber, and smoothly removing it from the patient's chest skin.

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] This utility model relates to a personalized pectus excavatum correction device, such as... Figure 1 As shown, the device includes a suction cup cover 100 and a suction cup skirt 300 detachably connected thereto. The suction cup cover 100 has an approximately circular or elliptical upper surface and a circumferential surface fixedly connected thereto. This circumferential surface is not on the same plane as the upper surface, but extends at a certain angle to the back side of the upper surface, thus forming an open space with the back side of the upper surface. The portion of the circumferential surface of the suction cup cover 100 away from the upper surface can be folded towards the open space to form an edge, which is not on the same plane as the circumferential surface and is orthogonal to the upper surface. With this arrangement, the suction cup cover 100 can be inserted into the surrounding engagement groove 310 provided on the annular top surface of the suction cup skirt 300 through this edge, ensuring an effective and secure connection.

[0027] Preferably, such as Figure 1 As shown, the suction cup skirt 300 with a hollow annular structure can be made of medical-grade soft silicone. Its bottom surface, opposite the top surface of the annular structure, forms an annular edge of a certain width, providing a good structural foundation for easy adhesion to the patient's chest skin and reducing skin irritation. When the suction cup skirt 300 is tightly attached to the patient's chest skin, the suction cup cover 100 can be inserted into the annular engaging groove 310 on the top surface of the suction cup skirt 300, thus forming a negative pressure chamber enclosed by the suction cup skirt 300, the suction cup cover 100, and the chest skin. The edge of the suction cup skirt 300 is designed to be slightly folded outwards to increase the contact area with the skin surface, enhance adhesion, and ensure no air leakage occurs when negative pressure is applied. By adjusting the air pressure changes within the negative pressure chamber, the therapeutic effect of this corrective device can be optimized. In particular, as... Figure 1As shown, the circumferential sidewall of the suction cup skirt 300 is provided with an outwardly protruding block-shaped flange 320. The flange 320 is square or circular and has a certain thickness and width. A lifting groove 330 with a certain curvature is formed on the bottom surface of the flange 320 towards its top surface. This lifting groove 330 matches the curvature of the fingertip, providing a point of application for the medical staff's fingers. After completing the pectus excavatum correction treatment, especially when a certain negative pressure is still maintained in the negative pressure cavity, the medical staff can easily lift the suction cup skirt 300 by inserting their fingers into the lifting groove 330, thereby effectively opening a corner of the suction cup skirt 300, eliminating the negative pressure environment in the negative pressure cavity, and safely removing it from the patient's chest skin.

[0028] Preferably, such as Figure 1 As shown, the upper surface of the suction cup cover 100 is designed as a recessed base 110 of a certain depth. This base 110 is preferably rectangular, with a recess depth less than the height of the negative pressure chamber to prevent contact with the patient's skin and subsequent scratches. The base 110 can accommodate a control box 200 and an air pump 210. The control box 200 is designed to be rectangular, with a length matching the length of the base 110, but a width slightly smaller than the width of the base 110 to ensure adequate installation clearance. The control box 200 is open at one end in the width direction so that the air pump 210 can be smoothly inserted into the control box 200 from this open end.

[0029] Preferably, such as Figure 2 As shown, the air pump 210 includes a mounting base 211 and a motor 214 mounted thereon. The motor 214 is powered by components such as a button battery to enable the air pump 210 to perform its gas suction function. The motor 214 is electrically connected to a control box 200, allowing the control box 200 to manage the start and stop of the air pump 210. The width of the mounting base 211 is designed to correspond to the width dimension of the end face of the control box 200, while its height is slightly lower than the height of that end face. This dimensional design aims to achieve the following: when the air pump 210 assembly is inserted from the open port of the control box 200 and fixed to the mounting base 211, the mounting base 211 can fit tightly with the end face of the control box 200 in the width direction, while leaving an appropriate gap in the height direction, thereby partially covering the end face of the control box 200. This design not only ensures a stable connection between the air pump 210 and the control box 200, but also maintains a channel for air circulation inside and outside the control box 200, ensuring smooth and efficient gas exchange.

[0030] Preferably, such as Figures 1-3As shown, the control box 200 is equipped with an air tube 230 to facilitate gas flow between the air pump 210 and the negative pressure chamber. One end of the air tube 230 is detachably connected to the control box 200, while the other end is guided and connected to a first mounting hole 120 on the upper surface of the suction cup cover 100. This hole is a through-hole design. Simultaneously, another extension of the air tube 230 passes through a pre-set second mounting hole 121 on the outer surface of the control box 200, thus connecting with the air pump 210. The mounting base of the air pump 210 integrates two functional interfaces: an air inlet 212 and an air outlet 213. Specifically, the corresponding end of the air tube 230 can be detachably and securely connected to the air inlet 212, while the air outlet 213 communicates with the external atmospheric environment through a pre-reserved gap between the mounting base 211 and the end face of the control box 200.

[0031] Preferably, such as Figure 4 As shown, the control box 200 has an adjusting member 220 on its side, comprising a head 221 and an insertion portion 222. The outer peripheral surface of the insertion portion 222 of the adjusting member 220 is machined with an external thread structure, which forms a threaded engagement with a pre-set internal thread hole on the side wall of the control box 200. Figure 3 As shown, during installation, when the control box 200 is placed inside the base 110, the adjusting member 220 abuts against the inner wall of the base 110 with its head 221. This tight physical contact between the adjusting member 220 and the base 110 provides the necessary mounting force for the control box 200. Furthermore, by rotating the head 221 of the adjusting member 220, medical personnel can precisely adjust the axial distance between its head 221 and the main body of the control box 200, thereby flexibly changing the contact force between the adjusting member 220 and the contact surface of the base 110, facilitating the assembly and disassembly of the box.

[0032] Preferably, in addition to being formed by recessing the upper surface of the suction cup cover 100, the base 110 can also have a hollow frame formed on the upper surface of the suction cup cover 100 to accommodate the control box 200. This design allows the control box 200 to be mounted on the base 110 in a manner that is approximately flush with or slightly higher than the suction cup cover 100 (depending on the bottom height of the base 110). Because of this arrangement, the base 110 does not intrude into the space of the negative pressure chamber, thus avoiding compression of the negative pressure chamber space. This design eliminates the need to create a recessed area on the suction cup cover 100 to accommodate the control box 200, which reduces the area requirements of the suction cup cover 100 and the suction cup skirt 300. The suction cup cover 100 and the suction cup skirt 300 can be designed to be more compact while still providing sufficient negative pressure chamber space for effective pectus excavatum correction treatment.

[0033] Preferably, the adjusting member 220 can also be a plurality of vertical, parallel protrusions provided on the side of the control box 200. In this configuration, the adjusting member 220 fixes the control box 200 by engaging with the base 110. Specifically, the side of the base 110 is pre-set with grooves that correspond in size, number, and position to the adjusting members 220 (protrusions) on the side of the control box 200. This configuration allows the control box 200 to engage with the adjusting members 220 (protrusions) along the extension direction of the adjusting members 220 (protrusions) in the corresponding grooves of the base 110, achieving a detachable connection between the control box 200 and the base 110. This engaging mechanism provides a simple fixing method, as the adjusting members 220 (protrusions) guide the control box 200 to slide into the inner wall groove of the base 110, ensuring the stability and safety of the control box 200 on the suction cup cover 100. In addition, the combination of ribs and grooves helps to reduce the movement or rotation of the control box 200 on the suction cup cover 100, ensuring the stability of the correction device during use.

[0034] Preferably, such as Figures 1-3 As shown, the end of the air tube 230 connected to the pre-set first mounting hole 120 on the upper surface of the suction cup cover 100 is equipped with a one-way valve 240, such as the Lee Company's LHQ series or the Clippard NIV series. The diameter of these valves matches the inner diameter of the first mounting hole 120, thereby achieving a highly airtight connection between the air tube 230 and the suction cup cover 100. The one-way valve 240 has an internal valve disc structure that opens or closes according to the gas flow direction. This structure typically employs a spring-loaded or gravity-driven design to ensure reliable performance under different pressure conditions. Specifically, when gas flows from the negative pressure chamber to the mounting box, the valve disc opens under the pressure difference, allowing gas to pass smoothly while maintaining low pressure loss. Conversely, when gas attempts to flow back from the mounting box to the negative pressure chamber, the valve disc closes rapidly under the action of the spring or gravity, thus forming an effective seal and preventing gas backflow. This design mechanism not only ensures the unidirectional flow of gas but also provides excellent response speed and sealing performance, preventing abnormal pressure increases within the negative pressure chamber due to backflow and ensuring the stability and reliability of the device.

[0035] Preferably, the control box 200 is equipped with a pressure sensor and a buzzer. The pressure sensor can be an MS5803-14BA, which has a small package size and is suitable for installation in the space-constrained control box 200. The buzzer can be a Buzzer-5B, which also features a small design and is suitable for integration into the compact control box 200. Particularly preferably, the base 110 has an opening corresponding to the pressure sensor, allowing the pressure-sensitive element of the pressure sensor to be placed into the negative pressure chamber. The base 110 has a regularly shaped opening corresponding to the pressure-sensitive element of the pressure sensor, allowing the pressure-sensitive element to directly extend into the preset negative pressure chamber, thus enabling it to directly sense pressure changes within the negative pressure chamber.

[0036] Preferably, such as Figure 3 As shown, the control box 200 has a display screen 260 on its surface, which is electrically connected to the air pressure sensor to display the air pressure changes monitored by the sensor in real time. The control box 200 also has several buttons 250 on its surface for electrical connection to the internal motor 214 and buzzer. Medical personnel can set the treatment time using the buzzer timer button 250 and control the operation of the air pump 210 using the air pump 210 start / stop function button 250. When the set treatment time is reached, the buzzer will sound to remind medical personnel to press the corresponding button 250 to stop the air pump 210 from continuing to operate.

[0037] Preferably, such as Figure 3 As shown, buttons 250 and displays 260 are arranged at both ends of the surface of the control box 200 with appropriate spacing, ensuring sufficient space in the central area of ​​the control box 200. Both buttons 250 and displays 260 are planar structures. Buttons 250 are in a regular shape such as a circle or rectangle, with a clearly defined touch area; displays 260 are preferably LED displays, capable of intuitively displaying air pressure information. This arrangement allows the air tube 230, connecting the first mounting hole 120 and the second mounting hole 121, to pass over the gap between buttons 250 and displays 260, avoiding obstruction of the operating interface. The layout of the air tube 230 is rationally designed, ensuring unobstructed airflow and facilitating clear viewing of information on the displays 260 and easy activation of buttons 250 by medical personnel during operation.

[0038] Preferably, addressing the issue that standard suction cup products cannot fit patients with different body shapes, the suction cup cover 100 of this invention is designed in a customized manner. Three-dimensional data of the patient's chest shape is obtained through techniques such as 3D scanning or 3D photography. Based on this data, a suction cup cover 100 conforming to the patient's actual body shape can be designed to effectively cover the area requiring treatment while reducing unnecessary space occupation, thereby improving the patient's wearing comfort.

[0039] It should be noted that the above specific embodiments are exemplary.
