Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a support frame for pleural effusion drainage. Background Technology

[0002] Pleural effusion is a common clinical syndrome characterized by the pathological accumulation of fluid in the pleural cavity. The pleural cavity is a potential space between the visceral and parietal pleura. In a normal person, the pleural cavity contains 5–15 ml of fluid, which plays a lubricating role during respiratory movements. 500–1000 ml of fluid is formed and absorbed in the pleural cavity daily. Pleural effusion can occur if any cause leads to increased fluid production or decreased fluid absorption in the pleural cavity. For patients with excessive pleural effusion, thoracentesis is a common, convenient, and simple diagnostic and treatment method.

[0003] Currently, in order to ensure that patients maintain a fixed posture during pleural effusion drainage, straps are usually used to fix patients to the chair. However, straps have poor stability, limited angle, and are not ideal for fixing the patient's chest and abdomen. Therefore, a support frame for pleural effusion drainage is provided. Summary of the Invention

[0004] The purpose of this application is to provide a support frame for pleural effusion drainage, so as to provide more stable support and fixation for the patient, ensure the stability of the patient during the drainage process, and facilitate the adjustment of the patient's forward and backward tilt angles.

[0005] To solve the above-mentioned technical problems, this application provides a support frame for pleural effusion aspiration, including two adjustable support frames for arm support and a fixed frame disposed between the two adjustable support frames, the fixed frame being used to fix the patient's chest and abdomen;

[0006] The adjustable support frame includes a support base plate, an adjusting rod, and an electric telescopic rod. One end of the adjusting rod and one end of the electric telescopic rod are rotatably connected to the support base plate via a first rotating shaft. The output end of the electric telescopic rod is rotatably connected to the end of the adjusting rod away from the support base plate via a second rotating shaft. The end of the adjusting rod away from the support base plate has an arc-shaped support plate rotatably connected to it via a rotating component.

[0007] The fixed frame includes two U-shaped plates with openings facing each other, a connector that can be detachably connected at both ends, and multiple adjusting plates. A ball block is fixedly installed on one side of each adjusting plate, and multiple ball holes for the ball block to rotate are opened on the inner wall of each of the two U-shaped plates.

[0008] Furthermore, each of the connecting components includes an elastic plate and a triangular locking block. One end of the elastic plate is fixed to the outer wall of one of the ends of the U-shaped plates, and the triangular locking block is fixed to the other end of the elastic plate.

[0009] Furthermore, the outer wall of the U-shaped plate, which is not connected to the elastic plate, is provided with a limiting groove for the triangular locking block to engage.

[0010] Furthermore, the U-shaped plate with the limiting groove is slidably disposed between the two elastic plates, and the cross-section of the elastic plate is U-shaped.

[0011] Furthermore, the adjusting rod and the electric telescopic rod are located at both ends of the supporting base plate.

[0012] Furthermore, telescopic sleeves are provided on both the front and rear sides of the fixed frame, and both ends of the telescopic sleeves are rotatably connected to the fixed frame and the supporting base plate respectively through the No. 3 rotating shaft.

[0013] Furthermore, the connection points of the telescopic sleeve and the electric telescopic rod with the supporting base plate are located in the same vertical plane.

[0014] Furthermore, the inner walls of both U-shaped plates are provided with multiple sets of annular notches for the rotation of the adjusting plate.

[0015] Furthermore, each of the U-shaped plates is provided with at least two adjustment plates, and the adjustment plates located within the U-shaped plates are evenly distributed.

[0016] Compared with the prior art, this application has at least the following beneficial effects:

[0017] 1. This pleural effusion aspiration support frame, through its arc-shaped support plate and U-shaped plate, can support the patient's arms and fix the position of the chest and abdomen during use, thereby ensuring the stability of the patient during the effusion aspiration process.

[0018] 2. The support frame for pleural effusion drainage can adjust the height and angle of the adjustable rod by extending and retracting the electric telescopic rod, thereby facilitating the adjustment of the patient's forward and backward tilt angles. Attached Figure Description

[0024] The pleural effusion drainage support frame of this application will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this application. It should be understood that those skilled in the art can modify the application described herein while still achieving the advantageous effects of this application. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this application.

[0025] The present application is described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present application will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present application.

[0026] like Figure 1-3 As shown in Figure 5, this application embodiment proposes a support frame for pleural effusion aspiration, including two adjustable support frames for arm support and a fixed frame disposed between the two adjustable support frames. The fixed frame is used to fix the patient's chest and abdomen. The adjustable support frame includes a support base plate 1 fixed to the armrest of a seat. The support base plate 1 can be fixed to the armrest of the seat by welding or clamping. It also includes an adjusting rod 2 and an electric telescopic rod 3. One end of the adjusting rod 2 and the electric telescopic rod 3 are rotatably connected to the support base plate 1 through a first rotating shaft. The output end of the electric telescopic rod 3 is rotatably connected to the end of the adjusting rod 2 away from the support base plate 1 through a second rotating shaft. The adjusting rod 2 and the electric telescopic rod 3 are located at opposite ends of the support base plate 1. The location of the adjusting rod 2 and the electric telescopic rod 3 at opposite ends of the support base plate 1 allows the electric telescopic rod 3 to better apply pressure to the adjusting rod 2, ensuring stability after adjustment. At the same time, the electric telescopic rod 3 is controlled to move up and down by an external wireless controller.

[0027] The end of the adjusting rod 2 away from the supporting base plate 1 is rotated by a rotating component to have an arc-shaped support plate 4. The fixed frame includes two U-shaped plates 5 with openings facing each other, a connector 6 for detachable connection between the two ends of the two U-shaped plates 5, and multiple adjusting plates 7. A ball block 8 is fixedly installed on one side of each of the multiple adjusting plates 7. Multiple ball holes for circumferential rotation of the ball block 8 are opened on the inner wall of each of the two U-shaped plates 5. Multiple sets of annular notches for rotation of the adjusting plates 7 are opened on the inner wall of each of the two U-shaped plates 5. The annular notches can increase the angle of circumferential rotation of the ball block 8 and the adjusting plate 7 within a specified range, such as a rotation range of 0-35°, so as to better and more stably contact the body of different patients.

[0028] The following are preferred embodiments of the support frame for pleural effusion drainage to clearly illustrate the content of this application. It should be understood that the content of this application is not limited to the following embodiments, and other improvements made by conventional technical means by those skilled in the art are also within the scope of this application.

[0029] like Figure 1 and 4 As shown. In this embodiment, each connector 6 includes an elastic plate 61 and a triangular locking block 62. One end of the elastic plate 61 is fixed to the outer wall of one of the U-shaped plates 5 ends, and the triangular locking block 62 is fixed to the other end of the elastic plate 61. The outer wall of the U-shaped plate 5, which is not connected to the elastic plate 61, is provided with a limiting groove for the triangular locking block 62 to engage.

[0030] When the two U-shaped plates 5 are spliced ​​together, the inclined surface of the triangular locking block 62 will abut against the side wall of the U-shaped plate 5, thereby generating a horizontal reverse force that can cause the elastic plate 61 to deform. When the triangular locking block 62 corresponds to the limiting groove, the elasticity of the elastic plate 61 itself can make the triangular locking block 62 quickly engage into the limiting groove, realizing the mutual connection of the two U-shaped plates 5. At the same time, according to the different limiting grooves set, it can realize the use of patients of different body types, increasing the applicability of the device.

[0031] A U-shaped plate 5 with a limiting groove is slidably disposed between two elastic plates 61. The cross-section of the elastic plate 61 is U-shaped, which can limit the position of the upper and lower sides of the connected U-shaped plate 5 after the two U-shaped plates 5 are spliced ​​together, effectively reducing the separation and rotation of the U-shaped plate 5 from the elastic plate 61. At the same time, the end of the elastic plate 61 near the triangular block 62 has an inclined surface, which makes it easy to manually move the elastic plate 61 to deform it and make the triangular block 62 separate from the limiting groove.

[0032] like Figure 2 As shown. In this embodiment, telescopic sleeves 9 are provided on both the front and rear sides of the fixed frame. Both ends of the telescopic sleeves 9 are rotatably connected to the fixed frame and the support base plate 1 respectively through the No. 3 rotating shaft, so that the fixed frame can be fixed to the two support base plates 1.

[0033] Through the No. 3 rotating shaft and the telescopic sleeve 9, the telescopic sleeve 9 can extend and retract during the lifting and lowering adjustment of the adjusting rod 2, and rotate with the No. 3 rotating shaft, so that the fixed frame and the adjusting rod 2 are linked together, and the fixed frame is prevented from being lost. The connection point between the telescopic sleeve 9 and the electric telescopic rod 3 and the supporting base plate 1 is located in the same vertical plane.

[0034] In summary, this pleural effusion aspiration support frame, when in use, has its support base plate 1 installed on the armrest of a chair. The patient sits on the chair, with their chest and abdomen positioned within a U-shaped plate 5. Another U-shaped plate 5 is then slidably inserted between the two elastic plates 61. When the two U-shaped plates 5 are joined together, the inclined surface of the triangular locking block 62 abuts against the sidewall of the U-shaped plate 5, generating a horizontal, opposing force that deforms the elastic plate 61. When the triangular locking block 62 aligns with the limiting groove, the elasticity of the elastic plate 61 itself... The triangular locking block 62 quickly engages into the limiting groove, connecting the two U-shaped plates 5 to fix the patient's chest and abdomen. The ball block 8 and the circumferentially rotating adjusting plate 7 automatically adjust the angle according to the patient's position, ensuring continuous stability. The arc-shaped support plate 4 allows the patient's arms to rest on top, supported by the adjusting rod 2 and the electric telescopic rod 3. The electric telescopic rod 3 extends and retracts, adjusting the angle of the adjusting rod 2. Ultimately, the patient assumes a reverse riding position, facilitating pleural effusion drainage by medical staff.

[0035] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
