Description

Technical Field

[0001] The invention relates to the technical field of structural design of equipment used for postoperative rehabilitation of cardiothoracic surgery, and in particular to a postoperative postoperative drainage support frame for cardiothoracic surgery. Background Art

[0002] Postural drainage therapy (PDT) is one of the commonly used airway clearance techniques in clinical practice. The technique was invented by Jean Chevaller in 1967. Its principle is to change the patient's body position and use gravity to drain sputum from the alveoli to the bronchi, thereby draining sputum. Prone position is a commonly used position in postural drainage, especially for patients after chest surgery, because the prone position can better use gravity to help sputum discharge and reduce pressure on the wound.

[0003] Postural drainage after cardiothoracic surgery is an important treatment technique, especially prone drainage, which can help patients more effectively discharge sputum and secretions from the lungs, thereby improving respiratory function and promoting postoperative recovery. In this postural drainage process, the use of cushions plays a vital role.

[0004] Postoperative cardiac surgery patients may have difficulty in coughing up sputum and increased airway secretions due to respiratory temperature and humidity regulation, lung exudation, anesthesia, pain, etc.; in addition, due to long-term bed rest, lung atelectasis, inability to cough, etc., the infection rate of lung infection is high, which is also the main cause of death in patients after cardiac surgery.

[0005] Conventional treatments for lung infections include postural drainage, prone ventilation, antibiotics, and endotracheal intubation followed by suction to maintain airway patency. Based on clinical practice, when patients undergo postural drainage, multiple sponge pads or pillows are placed on the patient's forehead and chest, and the patient's head is tilted to one side. This has disadvantages:

[0006] ① The patient's head and neck tilt to one side for a long time, and there is discomfort in the head and neck;

[0007] ② The tube of a patient with endotracheal tube is easily compressed and folded, affecting airway ventilation;

[0008] ③ There is a risk of pipeline slippage and pressure damage;

[0009] ④It is not convenient to move and has poor flexibility and adjustability. It can only meet the needs of bedridden patients, but cannot meet the drainage needs of patients in the recovery period when they sit at different times.

[0010] It can be seen that in the prior art, some patients need walking exercises in the later stage of rehabilitation, which is more conducive to the recovery of their condition. However, due to lack of physical strength after surgery, they can only do short-distance walking exercises and need to sit up in time to avoid secondary injuries to the patients. However, the prior art cannot meet the defects of patients doing short-distance exercises and sitting up in time. In addition, when sitting up or standing up, patients need to lie prone to drain phlegm to improve the rehabilitation effect. Summary of the invention

[0083] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0084] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0085] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0086] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0087] like Figure 1-Figure 11 As shown, the postoperative drainage support frame for cardiothoracic surgery includes: an auxiliary seat 01 for patients to sit and use, and a cushion pad 02 for patients to lie prone for drainage; the auxiliary seat 01 is fixedly connected to the cushion pad 02 via a support rod 51;

[0088] In order to meet the requirement of relatively fixed height of the auxiliary seat 01 and to meet the requirements of the cushion 02 for people of different heights, the support rod 51 includes: a lower fixed rod 53 for fixedly supporting the seat body 01 and an upper telescopic rod 54 for adjusting the height of the cushion 02. The upper end of the lower fixed rod 53 is fixedly connected to the upper telescopic rod 54, the lower end of the lower fixed rod 53 is fixedly connected to the upper side of the auxiliary seat 01, and the upper end of the upper telescopic rod 54 is fixedly connected to the cushion 02.

[0089] The cushion pad 02 includes: a fixed seat 1 for main support and an adjustment seat 2 that can be bent and adjusted or raised for support. The fixed seat 1 and the adjustment seat 2 can conveniently meet the patient's prone support, which is beneficial to the discharge of sputum in the patient's body and the patient's breathing. In order to adapt to the human head structure, especially to facilitate a certain amount of accommodation space for the facial trachea, the eyes, nose and mouth will not be compressed for a long time. The fixed seat 1 is a U-shaped structure. At the two U-shaped ports of the fixed seat 1 (the two ends of the U-shaped structure extending out of the side wall), the connection is made between the rotating adjustment device 3 and the adjustment seat 2. In particular, to avoid patients with endotracheal intubation who need to lie on their side, or medical staff who need to replace the endotracheal intubation or other medical care processes, the adjustment seat 2 can be bent down, and the patient can lie on his side to facilitate the retention of the endotracheal intubation and avoid interference.

[0090] In order to facilitate the fixing and connecting function of the entire fixing seat 1, especially to cooperate with other components, the bottom of one end of the fixing seat 1 away from the adjustment seat 2 is fixedly connected to a support frame 5, and the other end of the support frame 5 is connected to an upper telescopic rod 54. The upper telescopic rod 54 satisfies the use of the entire buffer pad 02 to set an adjustable height, thereby improving the use effect.

[0091] The auxiliary seat 01 includes: a support seat 6 for supporting and rolling, a curved rod 7 for supporting the seat body 8, and a seat body 8 for supporting the patient when sitting down. When the seat body 8 is not in use, it can be lifted off the ground to meet the needs of patients for walking exercises, and when needed, it can be easily rotated under the patient's body to meet the needs of patients for sitting. The upper side of the support seat 6 is fixedly connected to the lower fixed rod 53, and the outer wall of the lower fixed rod 53 is rotatably connected to the curved rod 7, and the other end of the curved rod 7 is fixedly connected to the seat body 8. It meets the requirements of convenient for patients to sit and use, and during walking exercises, the seat body 8 can be supported by the curved rod 7, which is convenient for patients to use with walking auxiliary support.

[0092] In order to facilitate the connection between the fixed seat 1 and the adjustment seat 2, and to facilitate the smooth bending of the adjustment seat 2 and the horizontal support of the patient. The rotation adjustment device 3 includes: a fixed groove 31 and a hinge groove 32 (both are channel steel structures), the side of the fixed groove 31 away from the opening is fixedly connected to the hinge groove 32 (that is, the bottom of the channel steel), and the opening directions of the hinge groove 32 and the fixed groove 31 are perpendicular; the opening direction of the fixed groove 31 is horizontal, and the opening direction of the hinge groove 32 is vertical. It is convenient to hinge the adjustment seat 2 and rotate it in the vertical plane. The fixed groove 31 and the fixed seat 1 are detachably connected; the adjustment seat can be easily assembled, and it can also meet the environment where the fixed seat 1 is used alone. The hinge groove 31 can adjustably hinge the adjustment seat 2. Adjustable hinge means that the adjustment seat 2 can rotate relative to the fixed seat 1, and the adjustment seat 2 can support the patient's head in a horizontal state. In order to facilitate the articulation of the adjustment seat 2 and to satisfy the two actions of supporting the patient's head in a horizontal state, a hinge slot 21 is provided at the end of the adjustment seat 2, and the hinge slot 21 is in the shape of a long strip. A hinge shaft 33 is fixedly connected between the two side walls of the hinge slot 32, and the hinge shaft 33 passes through the hinge slot 21; at the lower side of the hinge slot 21 (the lower side here refers to the lower side of the hinge slot 21 when the adjustment seat 2 is in a horizontal state), the bottom of the adjustment seat 2 is in an arc shape (the bottom here refers to the lower bottom surface of the adjustment seat 2 close to one end of the fixed seat 1 when the adjustment seat 2 is in a horizontal state);

[0093] When the hinge shaft 33 is at the lower end position of the hinge slot 21, the adjustment seat 2 rotates relative to the hinge slot 21;

[0094] The distance between the hinge slot 21 and the end of the adjustment seat 2 is the same as the distance between the hinge shaft 33 and the bottom of the hinge slot 21 , so that when the hinge shaft 33 is at the upper end of the hinge slot 21 , the adjustment seat 2 and the fixed seat 1 are relatively fixed.

[0095] That is to say, the adjustment seat 2 needs to realize two actions, the first is bending downwards, and the second is horizontal support.

[0096] First horizontal support: the hinge shaft 33 is in the hinge slot 21 , at which time the end of the adjustment seat 2 and the hinge slot 32 are in close contact, and due to the support of the hinge slot 32 , the adjustment seat 2 will not rotate.

[0097] The second downward bending: lift the adjustment seat 2, and the hinge shaft 33 slides downward along the hinge slot 21. When the hinge shaft 33 slides to the lowermost end of the hinge slot 21, the arc shape at the bottom of the adjustment seat 21 can rotate relative to the hinge slot 32 without interference, so that the adjustment seat 2 can be easily bent downward. Furthermore, in order to facilitate the adjustment of the adjustment seat 2 in the process of bending downward, the hinge slot 32 supported by the end of the adjustment seat 2 can be lowered more smoothly, and the adjustment of the adjustment seat 2 is inconvenient, and the rotation radius of the lower end of the hinge slot 21 is reduced. In particular, it is convenient for the adjustment seat 2 to be smoothly adjusted from a bent state to a horizontal state. It also includes: an extension slot 22, which extends from the lower end of the hinge slot 21 to one end close to the bottom of the hinge slot 32. When the adjustment seat rotates, the hinge shaft 33 is inside the extension slot 22, so the rotation radius of the arc-shaped lower end of the adjustment seat is reduced, which can increase the distance between the end of the adjustment seat 2 and the hinge slot 32 during the bending adjustment to the horizontal direction, so that the adjustment seat 2 can be bent downward smoothly.

[0098] In order to facilitate the fixed connection between the rotation adjustment device 3 and the fixed seat 1, it also includes: a locking member 4 with a locking and fixing function, the locking member 4 is fixedly connected to the lower side of the fixing groove 31, and the locking member 4 locks and fixes the fixing groove 31 and the fixing seat 1. In order to achieve detachability, especially to facilitate installation and disassembly operations. The locking member 4 includes: a pressing plate 41 that presses the fixing seat 1, a threaded rod 42 that is telescopic relative to the fixing groove 31, and an adjusting handle 43 that adjusts the rotation of the threaded rod 42. A threaded hole is provided through the lower side plate of the fixing seat 1, and the threaded rod 42 is threadedly connected through the threaded hole. The pressing plate 41 is fixedly connected to the upper end of the threaded rod 42, and the lower end of the threaded rod 42 is connected to the adjusting handle 43. In order to improve the patient's comfort, especially to avoid the occurrence of pressure sores during long-term prone use. A buffer layer 11 is fixedly connected to the upper side of the fixing seat 1 and / or the adjusting seat 2. The buffer layer 11 set on the upper side of the fixing seat 1 and the adjusting seat 2 here is set independently to avoid the buffer layer 11 interfering with the angle adjustment of the adjusting seat 2. In order to facilitate the fixed connection of the buffer layer 11, especially the buffer layer 11 can be screwed and fixedly connected with the fixing seat 1 after being produced in a separate process. The bottom of the buffer layer 11 is bonded with a fixing plate 12, and the fixing plate 12 and the fixing seat 1 and / or the adjustment seat 2 are fixedly connected by screws. In order to facilitate the patient's walking use, especially during the patient's walking exercise, the patient can be supported by the auxiliary support. The end of the adjustment seat 2 away from the fixing seat 1 is fixedly connected with an auxiliary handle 23. In order to facilitate the patient's sitting, it can also provide auxiliary support during the leaning process to avoid the bending rod 7 from bearing too much weight and bending the bending rod 7 to affect the use effect. The chair body 8 includes: a seat cushion 81 that supports the patient's buttocks, a connecting tube 82 that supports the support column 83, and a support column 83 that supports the ground. The upper end of the support column 83 is fixedly connected to the seat cushion 81, and the support column 83 is set through the connecting tube 82. The outer wall of the connecting tube 82 is fixedly connected to the bending rod 7. In order to realize that the support column 83 can be supported by the ground when the patient is sitting; when the patient is not sitting, such as when the patient is walking or standing, the lower end of the support column 83 can be smoothly separated from the ground. First, it is avoided that the lower end of the support column 83 will not rub against the ground during the walking process, affecting the movement of the crossbeam 62; second, when the patient is sitting, the support column 83 can be pressed down to support the ground, which can not only prevent the entire structure from slipping and avoid slippage affecting safety, but also avoid the patient's entire weight being carried on the curved rod 7, resulting in the bending of the curved rod 7. The inner wall of the connecting tube 82 is provided with a support cavity 84, and the outer wall of the support column 83 is fixedly connected with a support ring 85, which slides along the support cavity 84, and a support spring 86 is arranged between the support ring 85 and the bottom of the support cavity 84. That is to say, during the patient's walking process, due to the supporting effect of the support spring 86, the support column 83 will be pushed to move upward, the lower end of the support column 83 will be separated from the ground, and can be conveniently driven to rotate by the curved rod 7 to avoid affecting the patient's walking exercise.

[0099] When the patient needs to sit, the curved rod 7 can be used to drive the rotating support column 83 to the bottom of the patient's buttocks, so that the patient can sit conveniently. In addition, during the sitting process, due to the downward pressure of the patient's weight, the support column 83 can compress the support spring 86, the support spring 86 shrinks, and the support column 83 is supported in contact with the ground, avoiding the defect of being completely supported by the curved rod 7 and bending the curved rod 7. In addition, the anti-slip effect can be improved when the support column 83 and the ground are supported.

[0100] In order to improve the stability of the support seat 6, the support seat 6 can be stably moved when the patient needs to walk. The support seat 6 includes: a support plate 61 for supporting and fixing, and a crossbeam 62 for increasing the support area and improving stability. The lower sides of the two ends of the support plate 61 are fixedly connected to the crossbeam 62, and the bottom of the crossbeam 62 is fixedly connected to the rolling wheel 63; in order to meet the support function of a certain height, the upper side of the support plate 61 is fixedly connected to the lower fixed rod 53 to support and fix the curved rod 7. The lower fixed rod 53 meets the support function of the set height, thereby meeting the support function of the curved rod 7 for the set height of the support column 83.

[0101] In order to ensure that when the patient is not sitting, the curved rod 7 can fully support the support column 83, and can achieve that the support column 83 does not interfere with the cross beam 62 during the rotation process, increase the rotation angle of the seat body 8, and reduce the impact on the patient during the patient's walking exercise. The height of the support cavity 84 is greater than the height of the upper surface of the cross beam 62 from the ground. When the patient is not sitting, the seat body 8 can be supported by the support cavity 84 to the height of the support cavity 84, thereby ensuring that the seat body 8 is completely off the ground and does not interfere with the cross beam 62. In order to maximize the support area of ​​the cross beam 62, the patient's walking space can be increased, thereby reducing the impact on the patient's walking. The cross beam 62 is provided with two, and the two cross beams 62 are inclined away from the side of the support plate 61 to the side away from each other. Increase the patient's activity space, and will not reduce the support area. Under the premise of ensuring stability, it can facilitate the patient's activities. In order to further increase the activity space, under the requirement of ensuring the strength of the support plate 61, a circular arc transition port 64 is opened on the side of the support plate 61 close to the cross beam 62 to further increase the patient's activity space. In order to meet the adjustment of the position of the support plate 61, meet the requirements of comfort under different body shapes, heights or different physical conditions, the position of the support plate 61 can be easily adjusted. A plurality of connecting holes 65 are provided on the upper side of the crossbeam 62, and the support plate 61 is connected through the connecting holes 65 in an adjustable position. The number of holes provided on the support plate 61 is less than the number of connecting holes 65, so that the position of the support plate 61 can be adjusted. In order to increase the friction between the chair body 8 and the ground, the support stability of the chair body 8 is improved. The chair body 8 also includes: a base 87 for increasing the support area and a backrest 88 for improving the comfort of the patient, the bottom of the support column 83 is fixedly connected to the base 87, the bottom of the base 87 is provided with an anti-slip protrusion, and the backrest 88 is fixedly connected to the backrest 88 at the rear side of the seat cushion 81.

[0102] Preferably, the base 87 is a thin plate structure, so the base 87 can extend into the lower side of the cross beam 62. That is to say, when the patient stands up temporarily, the base 87 can extend into the lower side of the cross beam 62 to limit the rotation angle of the base 87. When the patient does not need the seat body 8 at all, the seat body 8 can be assisted to be pulled out from the lower side of the cross beam, and then pushed upward under the action of the support spring 86, so that the base 87 can be separated from the limit of the cross beam 62. In order to realize that the curved rod 7 can be easily rotated relative to the support rod 51, the curved rod 7 is connected to the support rod 51 through a rotating ring 71. In order to meet the support function of the rotating ring 71, the rotation of the rotating ring 71 can be met under the requirement of the support height. The outer wall of the support rod 51 is convexly provided with a fixed ring 52, and the rotating ring 71 is supported and connected to the upper side of the fixed ring 52; in order to limit the rotation angle of the rotating ring 71, and then meet the setting of the rotation position of the seat body 8, a movable groove 72 is opened on the inner wall of the rotating ring 71, and the support rod 51 extends into the limiting protrusion 73 inside the movable groove 72. By adjusting the rotation angle of the limiting protrusion 73 along the movable groove 72, the rotation position of the seat body 8 is set, so as to avoid the seat body 8 rotating too far and failing to meet the patient's need to sit. The seat body 8 can be rotated to the bottom of the patient's buttocks in time, and the rotation angle should not be too large, so that the patient can manually move the seat body 8 to the bottom of the patient's buttocks. In order to meet the requirement that the seat body 8 is in a position away from the patient in a natural state, the seat body 8 can be rotated when necessary so that the seat body 8 can be away from the patient during the patient's walking exercise, thereby reducing the possibility of interference. A return spring 74 is connected to the support of one side of the limiting protrusion 73 and the movable groove 72. Driven by the return spring 74, the rotating ring 71 rotates, driving the seat body 8 to rotate, and the seat body 8 is away from the patient, so as not to affect the patient during the patient's walking.
