Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical fixation devices, in particular to a patient body position fixing device for catheter room. BACKGROUND

[0002] In the process of catheter room intervention diagnosis and treatment, it is crucial to ensure that the patient maintains a stable and comfortable body position on the operating table, which not only relates to the accuracy of the operation, but also directly affects the safety and experience of the patient; at present, when fixing the patient in clinical practice, conventional restraint belts, fixing pads or rigid supports and other devices are usually used.

[0003] However, the existing fixing devices mostly focus on the constraint of the overall posture, and the separate treatment of the limbs often lacks sufficient flexibility and adaptability. Most of the fixing belts or supports are made of hard materials and have fixed shapes, which cannot well fit the physiological curvature and soft tissue characteristics of the patient's limbs. In the operation that requires a long time to maintain a specific posture, this rigid or semi-rigid fixing method is easy to cause local pressure on the patient's limbs, leading to a decrease in comfort, and may even cause pressure-induced nerve damage or poor local blood circulation, especially for elderly, thin or poor circulation patients, the risk is more prominent; due to the lack of effective flexible clamping and wrapping, the limbs of the patient may still displace when unconsciously moving or slightly moving, which not only affects the stability of the operation area, but also may increase the risk of catheter displacement or other operation accidents. SUMMARY

[0004] The present application provides a patient body position fixing device for catheter room, which has the advantages of flexible adaptation, stability and reliability, and can effectively improve the comfort of the patient, to solve the problem that the existing fixing device cannot fit the physiological curvature due to the hard material and fixed shape, which easily leads to pressure injury and poor blood circulation of the patient's limbs, and cannot effectively limit the micro-motion of the limbs during the operation, affecting the stability of the operation.

[0005] To achieve the above purpose, the technical scheme adopted by the present application is as follows: a patient body position fixing device for catheter room, comprising a moving assembly, a positioning assembly is fixedly installed on the top of the moving assembly, further comprising a linkage flexible fixing mechanism, the linkage flexible fixing mechanism comprises a first fixing assembly, the first fixing assembly is fixedly installed on the top of the positioning assembly, a lifting assembly is inserted into the left side of the first fixing assembly, four second fixing assemblies are fixedly installed on the left side of the lifting assembly; the second fixing assembly comprises a circular shaft, a C-shaped bent rod is fixedly connected to the outer edge of the circular shaft, two triangular bodies are fixedly sleeved to the outer edge of the C-shaped bent rod, rubber strips are fixedly connected to the top of the two triangular bodies, gas bags are fixedly connected to the other ends of the two rubber strips, friction grooves are arranged on the edges of the two gas bags, a second elastic belt is penetratingly installed inside the C-shaped bent rod on the inner side of the two triangular bodies, and air inlet tubes are fixedly connected to one end of the two gas bags.

[0007] Preferably, the moving component includes four omnidirectional wheels, with a fixing strip fixedly installed on the top of each pair of omnidirectional wheels, and a frame fixedly installed on the top of the two fixing strips. Two sets of semi-circular grooves are opened on the front and rear sides of the frame, and protruding rods are fixedly connected to the left and right sides of the frame.

[0008] Preferably, the frame is composed of a rectangular frame and multiple equidistant round rods, and round shafts are movably engaged in both sets of semicircular grooves, and the round shafts can rotate within the semicircular grooves.

[0009] Preferably, the positioning component includes a long plate, which is fixedly installed on the top of the frame. The long plate has multiple equidistant ventilation holes, a recessed groove on the top right side of the long plate, and two sets of notches on the left side of the groove.

[0010] Preferably, a first fixing component is fixedly installed in the groove, and the distance between the two notches on the right side is greater than that between the two notches on the left side.

[0011] Preferably, the first fixing component includes a fixing block, which is fixedly installed on the top of the groove. An air cushion is movably installed on the inner side of the fixing block. Two clamping blocks are fixedly installed on the top of the fixing block. A first elastic band is installed through the two clamping blocks. A sponge pad is fixedly sleeved on the middle position of the first elastic band.

[0012] Preferably, a second air pump is installed inside the fixing block, the second air pump is fixedly connected to the side of the air cushion, and two round holes are opened at the left end of the fixing block.

[0013] Preferably, the support assembly includes a U-shaped rod, which is inserted into two round holes in a fixing block. The U-shaped rod is divided into a left rod and a right rod.

[0015] The beneficial effects of this invention are as follows: 1. This invention achieves three-dimensional wrapping fixation of the patient's limbs through the synergistic effect of an airbag assembly controlled by an air pump and a second elastic band. After inflation, the airbags can adaptively conform to the physiological curvature of the limbs, dispersing concentrated pressure into a large area of ​​surface contact. Combined with the friction groove structure on the surface of the airbags, sufficient friction is provided while avoiding local hard compression, thereby effectively preventing compressive nerve damage and poor blood circulation that may be caused by prolonged fixation. It is especially suitable for elderly, thin and other vulnerable patients, significantly improving patient comfort and surgical safety.

[0016] 2. This invention utilizes a flexible fixation mechanism that integrates trunk fixation, head and neck support, and limb restraint. Through an adjustable-height support component and an inflatable / deflatable air pillow, it precisely adjusts and stabilizes the patient's head and neck in a neutral and comfortable position. Simultaneously, an asymmetrically installed second fixation component, designed to address the different physiological characteristics of the upper and lower limbs, combined with trunk restraint, ensures the patient's overall stability on the operating table. This comprehensive and precise positioning management effectively prevents unintentional patient movement during surgery, providing a stable surgical environment for delicate procedures such as catheter intervention and reducing the risks associated with catheter displacement.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figures 1-7 The system includes a movable component 1, a positioning component 2 fixedly mounted on the top of the movable component 1, and a linkage flexible fixing mechanism, which includes a first fixing component 3 fixedly mounted on the top of the positioning component 2. A lifting component 4 is inserted into the left side of the first fixing component 3, and four second fixing components 5 are fixedly mounted on the left side of the lifting component 4. The second fixing components 5 include a round shaft 51, a C-shaped bent rod 52 fixedly connected to the outer edge of the round shaft 51, two triangular bodies 53 fixedly sleeved on the outer edge of the C-shaped bent rod 52, and rubber strips 54 fixedly connected to the top of each of the two triangular bodies 53. Each airbag 55 is fixedly connected to the other two airbags 55. Friction grooves 56 are provided on the edges of each airbag 55. A second elastic band 57 is installed through the C-shaped bent rods 52 inside the two triangular bodies 53. An air inlet pipe 58 is fixedly connected to one end of each airbag 55. The two sets of second fixing components 5 are symmetrically installed. The installation distance between the two second fixing components 5 on the right side is greater than the installation distance between the two second fixing components 5 on the left side. The second elastic band 57 is installed through the two symmetrically installed C-shaped bent rods 52. The air inlet pipe 58 is a one-to-four pipe and is fixedly connected to one end of each of the four airbags 55. The other end of the air inlet pipe 58 is connected to a first air pump. For the patient's limbs, two symmetrical triangular bodies 53 and their rubber strips 54 and air bladders 55 can form a preliminary embracing wrap around the limbs from the sides or all sides. The first air pump connected through the air inlet pipe 58 can simultaneously inflate or deflate the four air bladders 55. When inflated, the soft air bladders 55 will deform and closely fit the physiological curvature and soft tissue of the patient's limbs, changing the fixed surface contact into a softer three-dimensional wrapping contact. The friction groove 56 increases the friction of the contact surface, while its groove structure avoids complete sealing and compression, which is conducive to the microcirculation and air circulation of the local skin. Once the airbag 55 inflates and wraps around the limb, the second elastic band 57 provides a stretchable, centripetal restraint force, which works in conjunction with the wrapping force of the airbag 55 to stabilize the limb in the center position of the C-shaped bend 52, preventing it from swaying or rotating inside the airbag 55.

[0022] The movable component 1 includes four casters 11. A fixing strip 12 is fixedly installed on the top of every two sets of casters 11. A frame 13 is fixedly installed on the top of the two fixing strips 12. Two sets of semi-circular grooves 14 are opened on the front and rear sides of the frame 13.

A round shaft 51 is movably engaged in the two sets of semi-circular grooves 14. The round shaft 51 can rotate within the semi-circular grooves 14. The four casters 11 at the bottom enable the entire device to move flexibly, making it easy to position and move within the conduit chamber. The frame 13 and its semi-circular groove 14 provide the mounting base for the superstructure.

[0023] The positioning component 2 includes a long plate 21, which is fixedly installed on the top of the frame 13. The long plate 21 has multiple equidistant ventilation holes 22. A recessed groove 23 is provided on the top right side of the long plate 21. Two sets of notches 24 are provided on the left side of the groove 23.

Then, the neck pillow 48 is installed. After that, the second air pump is started to control the inflation and deflation. The head pillow will fit the patient's head, so that the neck pillow 48 and the first elastic band 34 can be precisely adjusted to the most suitable height for the patient, ensuring that the head and neck are in a neutral and comfortable position and preventing displacement during the operation.

[0025] The lifting component 4 includes a U-shaped rod 41, which is inserted into two round holes in the fixing block 31. The U-shaped rod 41 is divided into a left rod and a right rod. The outer edge of the right rod has multiple equidistant triangular holes 42. A shell 43 is sleeved on the outside of the triangular holes 42.

Insert the U-shaped rod 41 into the fixing block 31. Through the engagement of the spring 44 and the triangular block 45 with the triangular hole 42, the height can be adjusted to multiple positions. After that, start the second air pump to control the inflation and deflation. The head pillow will fit the patient's head, so that the neck pillow 48 and the first elastic band 34 can be precisely adjusted to the most suitable height for the patient, ensuring that the head and neck are in a neutral and comfortable position and preventing displacement during the operation.

[0026] Working principle: When using this device, the four casters 11 at the bottom enable the entire device to move flexibly, facilitating positioning and transfer within the catheterization chamber. The frame 13 and its semi-circular groove 14 provide the mounting base for the upper structure. The long plate 21 serves as the main support surface for the patient's torso, and the ventilation holes 22 on it enhance breathability and improve comfort. The recessed groove 23 and its notch 24 are used for precise installation of the first fixation component 3 and guidance of the second fixation component 5, achieving structural integration and order. The first elastic band 34 and the sponge pad 35 work together to flexibly restrain the patient's head. Then, the U-shaped rod 41 is inserted into the fixing block 31. Through the engagement of the spring 44 and the triangular block 45 with the triangular hole 42, multiple height adjustments are achieved. After that, the second air pump is started to control the inflation and deflation. The head pillow will fit the patient's head, so that the neck pillow 48 and the first elastic band 34 can be precisely adjusted to the most suitable height for the patient, ensuring that the head and neck are in a neutral and comfortable position and preventing displacement during the operation. For the patient's limbs, two symmetrical triangular bodies 53 and their rubber strips 54 and air bladders 55 can form a preliminary embracing wrap around the limbs from the sides or all sides. The first air pump connected through the air inlet pipe 58 can simultaneously inflate or deflate the four air bladders 55. When inflated, the soft air bladders 55 will deform and closely fit the physiological curvature and soft tissue of the patient's limbs, changing the fixed surface contact into a softer three-dimensional wrapping contact. The friction groove 56 increases the friction of the contact surface, while its groove structure avoids complete sealing and compression, which is conducive to the microcirculation and air circulation of the local skin. Once the airbag 55 inflates and wraps around the limb, the second elastic band 57 provides a stretchable, centripetal restraint force, which works in conjunction with the wrapping force of the airbag 55 to stabilize the limb in the center position of the C-shaped bend 52, preventing it from swaying or rotating inside the airbag 55.
