Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a sputum suction device for transporting critically ill patients. Background Art

[0002] During the transportation of critically ill patients, ensuring that the patient can breathe freely is a crucial medical link, and suction is one of the key means to maintain unobstructed breathing. Traditional suction devices can meet basic suction needs in daily ward environments, but when it comes to the transportation of critically ill patients, many problems are exposed. On the one hand, there are various bumps and vibrations during transportation, and ordinary suction devices lack effective anti-collision and balancing mechanisms. The device is easily damaged by collision, causing key components such as suction cans and suction pumps to fail to work properly, directly affecting the suction effect and endangering the patient's life. Moreover, on uneven roads or during emergency movement, the device is difficult to maintain balance, which may cause the internal structure to shift, further interfering with the stability of the suction operation. On the other hand, the suction device is not well compatible with the treatment bed during transportation. In actual operation, it is often necessary to fix the suction device on the treatment bed so that medical staff can operate it conveniently during transportation. However, the existing suction device lacks a convenient and reliable fixing device, and it is difficult to quickly and firmly connect to different types of treatment beds, which may cause the device to shake or slip during transportation, increasing the risk of operation.

[0003] For example, a sputum suction device for medical patient transportation with patent number CN210932951U includes a box body and a clamping structure, the clamping structure includes a clamping block, the upper end of the clamping block is fixedly connected to a connecting rod, the upper end of the connecting rod is fixedly connected to a connecting plate, the lower end of the clamping block is longitudinally threaded with a threaded rod, the upper end of the threaded rod is rotatably connected to a fixed plate, a negative pressure pump and a collecting cylinder are respectively provided in the inner cavity of the box body, a hose is provided on the outside of the collecting cylinder, the negative pressure pump and the collecting cylinder, as well as the collecting cylinder and the hose are connected through a connecting pipe, a ring sleeve is provided on the outer side of the hose, a clamp is provided in the inner cavity of the ring sleeve, the clamp is slidably connected to the outer side of the hose, and the sputum suction device is installed and used during the transportation of critically ill patients by pushing the fixed plate through a screw rod, and an elastic connection is provided between the fixed cylinder and the movable cylinder, as well as the protection of the hose by the clamp can effectively prevent the patient's teeth from biting the hose and affecting the sputum suction. It is obvious that the device only relies on the elastic connection between the fixed cylinder and the movable cylinder to buffer vibration, and cannot provide all-round protection. During the transportation process, once a violent collision occurs, the box and key internal components of the traditional device, such as the negative pressure pump and the collection cylinder, are easily damaged, resulting in the inability to properly perform the sputum suction function. The device does not have a balance system and cannot reduce the interference of tilting or shaking on the stability of the sputum suction operation. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems of the existing device being easily damaged by collision, difficult to maintain balance, and poor adaptability to the treatment bed.

[0005] In order to achieve the above-mentioned purpose, the technical ideas adopted by the present invention to solve the technical problems are as follows: In order to solve the problem of easy collision, an anti-collision frame is provided, in which the sputum suction device can be placed, and the gap is large for easy operation.

[0006] In terms of improving stability, a circular mounting groove that precisely fits the outer diameter of the universal ball is set on the side of the anti-collision frame in the top center area, and the rotating seat is installed in an interference fit manner to ensure the stable rotation of the universal ball, so that the L-shaped liquid chamber and related structures can flexibly adjust the angle to assist in balance adjustment. At the same time, the connection seat installation area is evenly distributed at the bottom of the corresponding counterweight block, and the connection seat at the bottom of the counterweight block is fastened with bolts. The spring of the traction part is used to effectively deal with the tilt of the device, ensuring the stability of the suction device during transportation.

[0007] In terms of adaptability to the treatment bed, the sliding rod and the fixed rod can be adjusted to different lengths by cooperation. The clamping piece connected to the end of the sliding rod has a U-shaped clamping groove. One end of the clamping rod is rotatably arranged in the clamping groove through a pin. Rotating the clamping rod can firmly clamp the edge of the treatment bed between the clamping groove and the clamping rod.

[0008] In order to achieve the above object, the technical solution adopted by the present invention to solve the technical problem is: A sputum suction device for transferring critically ill patients comprises a sputum suction device, wherein the sputum suction device is placed in an anti-collision frame, a balancing device and a base rotatably connected to the bottom of the balancing device are arranged at the bottom of the anti-collision frame.

[0009] Furthermore, the balancing device comprises: The L-shaped column has an L-shaped liquid cavity filled with liquid inside, a piston rod 1 is movably arranged in the vertical cavity of the L-shaped liquid cavity, the other end of the piston rod 1 is fixed to the bottom of the anti-collision frame, and a piston rod 2 is movably arranged in the horizontal cavity of the L-shaped liquid cavity; The counterweight block is arranged below the anti-collision frame, and its side is movably connected with the second piston rod. A traction part is arranged at the bottom of the counterweight block for traction and resetting the counterweight block; The top of the rotating part is fixedly connected to the bottom of the L-shaped liquid chamber, and the bottom is rotatably connected to the base.

[0010] Further, the rotating part comprises: A universal ball is arranged on the top of the base through a rotating seat, and its top is fixedly connected to the bottom of the vertical chamber; The buffer is arranged at the bottom of the universal ball and is used to limit the rotation range of the universal ball.

[0011] Furthermore, the buffer comprises: A rotating column is fixed to the bottom of the universal ball and is provided with an active cavity inside. A spring is provided in the cavity. A telescopic rod is fixed to the other end of the spring. The telescopic end of the telescopic rod is located outside the rotating column. The ellipsoid cavity is arranged in the base and located at the bottom of the rotating seat, and the telescopic end of the telescopic rod slides and abuts against the ellipsoid cavity.

[0012] Furthermore, the L-shaped liquid cavity is filled with damping liquid, and the damping liquid flows in the vertical cavity and the horizontal cavity.

[0013] Furthermore, the traction part is a plurality of springs, which are arranged in a circle with the counterweight as the center, with one end of the springs being arranged at the top of the base and the other end being arranged at the bottom of the counterweight.

[0014] Furthermore, a fixing device is provided on one side of the base, including: There are several fixing rods, one end of which is fixed to the outside of the base; A sliding rod is sleeved on the other end of the fixed rod, and a locking device is provided at the end thereof; The clamping piece is connected to the other end of the sliding rod and is used for clamping the treatment bed.

[0015] Further, the clamping member comprises: Card slot; The clamping rod is rotatably arranged in the clamping groove.

[0016] Furthermore, a placement groove is provided on the top of the base, which is arranged below the counterweight block and is used to place the traction part. A ring-shaped inclined arc-shaped slide is provided on the top edge of the placement groove to guide the counterweight block to swing.

[0017] Furthermore, a plurality of rubber strips are arranged on the edge of the inner ring of the landslide to prevent foreign objects from falling into the placement groove and reduce the swing resistance below the counterweight block.

[0018] The beneficial effects of the present invention are: 1. By setting up an anti-collision frame, all-round protection is provided for the suction pump, which effectively reduces the risk of damage to the suction pump due to collision during transportation and ensures the continuous suction operation.

[0019] 2. The use of a balancing device, including an L-shaped liquid chamber, a counterweight and other structures, can automatically adjust the center of gravity of the equipment under bumpy road conditions, ensuring that the suction device always maintains a constant height and reducing interference with the stability of the suction operation.

[0020] When the equipment suddenly encounters a tilting condition during operation, the traction unit and the buffer immediately work together. The traction unit quickly applies a stable and moderate traction force to the balancing device by means of the pulling and thrust forces applied to the counterweight in multiple directions, thus preventing the device from excessively responding to the tilt and causing drastic displacement. The buffer absorbs and resolves the impact energy caused by the tilt of the universal ball through the coordination of the telescopic rod and the ellipsoidal cavity, effectively suppressing unnecessary swinging of the universal ball during the tilting process. The two complement each other to ensure that the entire return process is smooth and orderly, so that the equipment can still maintain a relatively stable posture in a tilted state. As the tilt angle gradually decreases, the equipment tends to be stable. At this time, the traction unit and the buffer continue to play a role, further fine-tuning the state of the balancing device so that it can return to its position accurately, ensuring the stability and reliability of the subsequent operation of the equipment.

[0021] 4. With the help of adjustable fixing devices, such as a combination of a fixing rod, a sliding rod and a clamping piece, it can quickly adapt to the structure of different types of treatment beds, realize the firm installation of the suction device on the treatment bed, and facilitate the operation of medical staff.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments.

[0025] In the description of the present invention, it is necessary to understand that the terms "front", "rear", "left", "right", "up", "down", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] refer to Figure 1-13 The present invention provides a sputum suction device for the transfer of critically ill patients, including a sputum suction device 10, which is placed in an anti-collision frame 20. A balancing device 30 and a base 40 rotatably connected to the bottom of the balancing device 30 are provided at the bottom of the anti-collision frame 20.

[0027] In specific implementation, the sputum suction device 10 is an existing structure, including a sputum suction cup 11 and a suction pump 12. The sputum suction cup 11 is a cylindrical container with an opening on the top for connecting the connecting pipe and the suction pipe. The material is transparent and chemically resistant polycarbonate, which is convenient for observing the sputum collection. It is tightly connected to the connecting pipe through a threaded connection to ensure sealing and prevent sputum leakage. The suction pipe is used to connect to the patient's mouth to extract sputum.

[0028] The suction pump 12 adopts a small and efficient electric diaphragm pump. Its shell is made of aluminum alloy, which has good heat dissipation and corrosion resistance. The suction pump 12 is connected to the sputum suction cup 11 through a special connecting pipe, and the two ends of the connecting pipe are fixed with sealing rubber rings and clamps to ensure that the connection is firm and leak-proof.

[0029] When in use, the suction pump 12 is started to generate negative pressure in the sputum suction cup 11 through the connecting pipe, and the suction pipe draws sputum into the sputum suction cup 11.

[0030] During specific implementation, the anti-collision frame 20 is an elliptical frame structure, which is slightly larger than the suction pump 10 and can fully accommodate the suction pump 10. The main body of the frame is made of high-strength aluminum alloy, which has the characteristics of light weight and high strength. The edges are connected into one by welding, and the welding points are uniform and firm, ensuring the stability of the overall structure of the frame. The top is hollowed out to observe the internal situation of the suction pump, and the hollow gap is large enough to put your hand in for fine-tuning. The bottom surface is a metal base plate, and the suction pump 10 is fixed to it by bolts. During transportation, if a collision occurs, the frame can absorb and disperse the impact force, effectively reducing the risk of damage to the suction pump 10, ensuring the integrity of the internal electronic components and structure of the suction pump 10, and ensuring that the suction operation can proceed normally.

[0031] In a specific implementation, the balancing device 30 includes an L-shaped column, a counterweight block 31 and a rotating portion 33 .

[0032] An L-shaped liquid chamber 32 is provided in the L-shaped column. The L-shaped liquid chamber 32 is formed by vertically connecting a vertical chamber 320 and a horizontal chamber 321 to form an L-shape. The two are connected through and four L-shaped liquid chambers 32 are evenly distributed in a cross shape below the anti-collision frame 20. The vertical chamber 320 and the horizontal chamber 321 are both cylindrical. The chamber is made of high-strength, impact-resistant engineering plastics, such as polyoxymethylene, or metal, and the interior is smooth, which is convenient for the flow of damping liquid. The top of the vertical chamber 320 is open, and it is movably connected to the piston rod 1 322 through a sealing rubber pad and a fastening bolt to ensure that the piston rod 1 322 can slide freely up and down in the vertical chamber 320 without leaking. The other end of the piston rod 1 322 is fixed to the bottom of the anti-collision frame 20, and one end of the horizontal chamber 321 is open, and it is also movably connected to the piston rod 2 323 through a sealing rubber pad and a fastening bolt. And the piston rod 1 322 and the piston rod 2 323 can rotate in the L-shaped liquid chamber 32.

[0033] When the anti-collision frame 20 tilts to one side, the piston rod 1 322 on the corresponding side slides downward in the vertical chamber 320, causing the damping liquid in the L-shaped liquid chamber 32 to flow between the vertical and horizontal chambers, and making the damping liquid in the horizontal chamber 321 tend to flow outward, driving the piston rod 2 323 to move outward for shock absorption, thereby preventing the suction device 10 from generating excessive vibrations and causing the liquid level in the suction cup 11 to shake.

[0034] The counterweight block 31 is conical and made of high-density cast iron to ensure sufficient mass for balance adjustment. An annular groove 311 is provided on its side to engage with the clamping head at the end of the second piston rod 323, which is tightly connected and can ensure that the second piston rod 323 can move sideways and drive the counterweight block 31 to move freely. Several connecting seats are welded on its bottom for connecting the traction part 310.

[0035] The traction part 310 is located at the bottom of the counterweight 31 and is arranged in a circle with the counterweight 31 as the center. One end of the traction part 310 is tightly fixed to the top of the base 40 by welding, and the other end is connected to the connection seat at the bottom of the counterweight 31. This position structure allows the counterweight 31 to move and stretch the spring when the device tilts to offset the impact force caused by the sudden tilt, and when the device restores the balance trend, the spring contracts to pull the counterweight 31 to return to its original position.

[0036] When the anti-collision frame 20 tilts, the counterweight 31 moves to the tilted side, driving the piston rod 2 323 to slide in the horizontal chamber 321, and the piston rod 1 322 to slide in the vertical chamber 320, causing the damping fluid in the L-shaped liquid chamber 32 to flow between the vertical and horizontal chambers. The damping fluid converts the horizontal force into the vertical force, pushing the counterweight piston rod 1 322 to slide slowly upward, thereby helping the anti-collision frame 20 to restore balance.

[0037] The rotating part 33, including the universal ball 331 and the buffer 332, is made of stainless steel with a smooth surface and high hardness. It is installed on the top of the base 40 through the rotating seat 42. The inner ring of the rotating seat 42 is tightly matched with the universal ball 331, and the outer ring is fixedly connected to the mounting groove on the base 40. The bottom of the rotating seat 42 is hollowed out and connected with the ellipsoid cavity 3323. The top of the universal ball 331 is fixed to the bottom of the vertical chamber 320 by welding to ensure a firm connection.

[0038] When the device tilts or turns, the universal ball 331 rotates freely in the rotating seat 42, driving the L-shaped liquid chamber 32 and the upper structure to adjust the angle, thereby assisting in balance adjustment.

[0039] The buffer 332 includes a rotating column and an ellipsoidal cavity 3323 opened at the top of the base 40, wherein the rotating column is provided with an active cavity 3321, and the rotating column is cylindrical and fixed to the bottom of the universal ball 331 and connected by welding. A spring is welded at the top of the active cavity 3321, one end of the spring is fixed in the cavity, and the other end is connected to the telescopic rod 3322. The ellipsoidal cavity 3323 is half ellipsoidal and is arranged in the base 40, at the bottom of the rotating seat 42. The telescopic rod 3322 is cylindrical and has a smooth round head at the bottom, and can slide freely in the ellipsoidal cavity 3323.

[0040] When the universal ball 331 rotates, the telescopic rod 3322 slides in the ellipsoid cavity 3323, and the spring is compressed or stretched. The spring force and the constraint of the ellipsoid cavity 3323 are used to limit the rotation range of the universal ball 331 to avoid excessive rotation causing the device to be unbalanced.

[0041] Working principle: When the device tilts and causes the anti-collision frame 20 to tilt, the piston rod 1 322 on the tilted side will move in the vertical chamber 320, and due to the blocking effect of the damping fluid, it will show a tendency to slowly slide down. Since the vertical chamber 320 and the horizontal chamber 321 are interconnected, the sliding of the piston rod 1 322 drives the damping fluid to circulate between the two chambers. The damping fluid in the horizontal chamber 321 is squeezed outward due to the flow trend, pushing the piston rod 2 323 to move outward synchronously. This series of actions effectively absorbs vibration energy, greatly reduces the vibration amplitude of the sputum suction device 10, and prevents the sputum in the sputum suction cup 11 from affecting the sputum suction operation due to excessive shaking. At the same time, under the action of gravity, the counterweight 31 moves in the tilting direction. During this period, the damping fluid in the L-shaped liquid chamber 32, by virtue of its viscosity, converts the horizontal force caused by the tilt into a vertical force, pushing the piston rod 1 322 to slowly slide upward, and the piston rod 2 323 in the opposite direction of the tilt is pulled by the counterweight 31 to gradually slide outward. At this time, due to the vacuum state in the L-shaped liquid chamber 32, the piston rod 2 323 sliding outward drives the damping fluid to flow in the horizontal chamber 321, thereby generating a downward attraction on the piston rod 1 322, alleviating the tilting trend of the anti-collision frame 20.

[0042] The traction part 310 is distributed in a circle with the counterweight 31 as the center, with one end firmly fixed to the top of the base 40 and the other end firmly connected to the connection seat at the bottom of the counterweight 31. During the movement of the counterweight 31, the spring of the traction part 310 is stretched, effectively offsetting the strong impact force generated by the sliding of the counterweight 31 at the moment of tilting. When the device tends to return to stability, the spring contracts, accurately pulling the counterweight 31 back to its original position, further strengthening the stability of the balance adjustment and preventing the counterweight 31 from swinging too much. The universal ball 331 in the rotating part 33 is installed on the top of the base 40 through the rotating seat 42, and the top is firmly welded to the bottom of the vertical chamber 320. When the posture of the device changes, the universal ball 331 rotates flexibly in the rotating seat 42, and the center is offset when tilted under the action of the upper half counterweight 31 and the L-shaped liquid chamber 32. The universal ball 331 drives the L-shaped liquid chamber 32 and the upper structure to quickly adjust the angle, providing strong support for balance adjustment. The buffer 332 that works in conjunction with it has an active cavity 3321 fixed at the bottom of the universal ball 331, and the bottom of the telescopic rod 3322 connected to the spring in the cavity slides smoothly in the ellipsoid cavity 3323 in the base 40. When the universal ball 331 rotates, the telescopic rod 3322 slides in the ellipsoid cavity 3323 accordingly, and the spring is compressed or stretched accordingly. Through the dual constraints of the spring elastic force and the ellipsoid cavity 3323, the rotation amplitude of the universal ball 331 is accurately controlled to prevent new imbalance problems caused by excessive rotation, ensuring that the balance adjustment process is stable and accurate.

[0043] In specific implementation, the base 40 is a columnar structure that is narrow at the top and wide at the bottom, which is convenient for both hanging and clamping and for flat use. It is made of high-strength aluminum alloy and is hollowed out inside for placing the control unit 41. Its upper surface is used to carry components such as the balancing device 30 and the sputum suction device 10, and the side is connected to the fixing rod 51.

[0044] A rotating seat 42 is provided at the top of the base 40, and four of them are arranged one-to-one with the universal balls 331. The mounting groove is circular, and the rotating seat 42 is fixed inside. The size of the rotating seat 42 is precisely adapted to the outer diameter of the universal ball 331. The depth of the mounting groove ensures that after the universal ball 331 is installed, its top can be smoothly welded and fixed to the bottom of the vertical chamber 320, and when the device is tilted or turned, the universal ball 331 can be flexibly rotated in the mounting groove through the rotating seat 42, and the bottom of the mounting groove is hollowed out to connect with the ellipsoid cavity 3323 to facilitate the rotation of the telescopic rod 3322 driven by the universal ball 331.

[0045] The installation area of ​​the traction part 310 is based on the top center of the base 40, and a placement groove 312 is opened at the position corresponding to the bottom of the counterweight block 31. The bottom of the placement groove 312 is a circular plane, and the top edge is provided with a ring-shaped inclined arc landslide, which is adapted to the bottom of the counterweight block 31 to prevent the counterweight block 31 from generating resistance when it tilts to the edge of the placement groove 312, and can cause the counterweight block 31 to slide along the arc surface and guide it back to the right position. A number of rubber strips 313 are provided along the inner ring edge of the landslide to prevent foreign objects from falling into the groove while reducing the resistance to the counterweight block 31. The bottom of the placement groove 312 is evenly distributed with a number of connecting seats, one end of the traction part 310 is connected to the connecting seat, and the other end is connected to the connecting column extending downward from the counterweight block 31.

[0046] When transporting in a vehicle, when a tilt occurs, the base 40 tilts in the same direction as the vehicle, and the counterweight 31 moves in the placement groove 312 along the tilt direction under the action of gravity to squeeze the rubber strip 313. The design of the rubber strip 313 reduces the resistance to the movement of the counterweight, and at the same time cooperates with the traction part 310 to keep the counterweight 31 centered in the vertical direction.

[0047] The fixing rod 51 is cylindrical and made of aluminum alloy. One end is fixed to the outside of the base 40 by welding. The fixing rod 51 consists of three fixing rods 51. The fixing rod 51 in the middle is shorter, and the fixing rods on both sides are longer and bent, so that the three fixing rods 51 face the same direction.

[0048] The sliding rod 52 is also cylindrical and made of aluminum alloy. Its inner diameter is precisely adapted to the outer diameter of the fixed rod 51, and it can slide smoothly along the axial direction outside the fixed rod 51, and the position is fixed by the locking device 521. The locking device 521 adopts a quick-release structure similar to the bicycle seat tube clamp, and is composed of a clamp body, a screw, a handle and other components. The clamp body is semi-circular and made of high-strength alloy steel. It has good toughness and strength and can withstand a large clamping force. The clamp body is movably connected to the end of the sliding rod 52 through a pin shaft to ensure that the clamp body can flexibly rotate around the pin shaft to achieve clamping operations at different positions. One end of the screw rod passes through the threaded hole on the clamp body and is fixedly connected to the handle, and the other end has a nut. When the position of the sliding rod 52 needs to be fixed, the handle is rotated, and the screw rod rotates in the threaded hole of the clamp body, pushing the clamp body to gradually hold the fixed rod 51, thereby achieving the position locking of the sliding rod 52.

[0049] The connection part of the clamping piece 53: The clamping piece 53 is connected to the end of the sliding rod 52 by bolts. The clamping groove 531 is in the shape of a U-shaped groove, and is made of high-strength engineering plastic with a certain elasticity, which can effectively adapt to the edge shapes of different treatment beds and avoid damage to the treatment bed. A threaded hole is opened on the lower side wall of the clamping groove 531. The clamping rod 532 is a cylindrical rod, one end of which is rotatably arranged in the threaded hole through a pin shaft, and a rubber plate is provided at the end to increase friction. A rotating block is provided at the other end of the clamping rod 532, which is processed with anti-slip grooves to facilitate the operator's rotation operation. Medical staff can slide the sliding rod 52 to adjust the position of the clamping piece 53 according to the structure of the treatment bed, align the clamping groove 531 with the edge of the treatment bed, and rotate the clamping rod 532 to clamp.

[0050] In the specific implementation, the control unit 41 uses an existing high-performance lithium battery pack, and two batteries are provided that can be replaced at any time. The battery is fixed inside the base 40 through a special battery box, and a sliding door is also provided on the outside of the base 40 for maintenance and replacement of batteries. The control unit 410 is a circuit board that integrates the power switch, suction pump control module, etc. for the existing touch-controlled intelligent sputum suction device. The control unit 410 is fixed inside the base 40 by bolts, and the touch panel is fixed on the outside of the base 40 for easy operation. The control unit 410 is connected to the battery and the connection wires of the suction pump 12 through connectors.
