Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of puncture assistance devices, and particularly relates to a multifunctional puncture catheterization bed. Background Technique
[0002] Puncture catheterization is a medical operation used to establish a venous access in a patient's body for treatments such as intravenous infusion, blood sampling, and monitoring central venous pressure. This technique is widely used clinically, including but not limited to PICC (Peripherally Inserted Central Catheter), CVC (Central Venous Catheterization), and Port-a-Cath. However, some patients need to lie in bed due to their condition for the puncture catheterization operation. When performing the puncture, the patient usually needs to stretch out the hand so that the hand forms an angle of about 90° with the body, which is more conducive to the puncture. However, when the patient is in bed, the width of the bed is limited and cannot fully support the patient's puncture arm. As a result, the patient's arm is in a suspended state during the puncture, and medical staff need to support the patient's arm or move other operating table auxiliary devices to support the patient's arm. However, neither of these two methods can keep the patient's arm stable during the puncture. Second, moving the operating table is troublesome and time-consuming, and the operating table needs to be moved away after the puncture is completed, which not only affects the puncture efficiency but also increases the physical consumption of medical staff, making the entire puncture process laborious and cumbersome. Therefore, there is an urgent need for a hospital bed that can facilitate the puncture catheterization operation. Content of the Utility Model
[0003] The purpose of the utility model is to provide a multifunctional puncture catheterization bed to solve the problem of laborious and cumbersome operation when a patient undergoes a puncture catheterization operation in a hospital bed.
[0004] To solve the above technical problems, the utility model provides the following technical solution: A multifunctional puncture catheterization bed includes a bed body and two arm platforms. The two arm platforms are located on both sides of the bed body. The arm platform includes a support plate and a support frame. The support plate is installed at one end of the support frame, and the other end of the support frame is rotatably connected to the lower surface of the bed body;
[0005] The support plate is used to place the patient's arm during the puncture catheterization operation;
[0006] In the initial state, the support frame is used to keep the support plate in a vertical state on both sides of the bed body as a guardrail of the bed body. During the puncture catheterization operation, the support frame is used to rotate and adjust the support plate to a horizontal state, and the surface of the support plate is at the same horizontal plane as the bed surface of the bed body.
[0007] Working principle of the utility model: Before puncture, the patient lies flat on the bed body. At this time, two support plates are vertically supported on both sides of the bed body. At this time, the support plates act as the guardrails of the bed body to prevent the patient from falling out of the hospital bed when turning over in the bed, providing safety protection. When performing puncture and catheterization, select the support plate on the corresponding side of the bed body according to the arm of the patient that needs to be punctured and catheterized, and then move the support plate. At this time, the support plate rotates with the support frame as the fulcrum. After the support plate rotates to the same plane as the bed surface, stop the rotation of the support plate, and then place the patient's arm on the support plate to perform the operation of puncture and catheterization. After the puncture and catheterization are completed, lift the support plate upward. At this time, the support plate rotates upward until it returns to the initial state.
[0008] Beneficial effects of the utility model:
[0009] 1. This solution upgrades the guardrail of the hospital bed by replacing the guardrail of the hospital bed with a support plate that can place the arm. In this way, usually the support plate acts as the guardrail of the hospital bed to prevent the patient from rolling out of the hospital bed. When puncture and catheterization are needed, move the support plate downward to make the support plate rotate to a horizontal state. At this time, the patient can place the arm on the support plate, and the support plate lifts the patient's arm. At this time, the doctor can perform the operation of puncture and catheterization on the support plate. The whole process does not need to carry other auxiliary operating tables for placing the arm. Just move the support plate downward, and the operation is simple. After the puncture is completed, push the support plate upward to make it return to the initial state. It not only saves time and effort, but also is simple and convenient to operate.
[0010] 2. The support plate can be used to lift the patient's arm for the operation of puncture and catheterization, and can also be used as the guardrail of the hospital bed, serving two purposes with one object, increasing the usage of the support plate and improving the utilization rate of the support plate.
[0011] Further, the bed body includes a bed frame and a bed board. The bed board is detachably connected to the bed frame. On both sides of the lower surface of the bed frame, a set of slide rails are respectively installed. Each set of slide rails has two slide rails, and the slide rails are perpendicular to the length direction of the bed body. On one side of the slide rails facing each other, there is a first chute. At the bottom of the first chute, there is a second chute. The width of the second chute is smaller than that of the first chute, and both the first chute and the second chute extend to the end of the slide rail. The support frame is an "L"-shaped support frame composed of a cross bar and a long bar. On both sides of the bottom end of the support frame, there are rotatably connected cylindrical rotating blocks. The two rotating blocks are respectively slidably connected in the first chutes of the two slide rails. On the opposite sides of the middle of the long bar, there are respectively fixedly connected cylindrical sliders. The sliders are used to slide in the second chutes, and the sliders correspond to the second chutes one by one. The cross bar is connected to the support plate. There is a pin hole at the bottom of the long bar, and there is also a pin hole on the slide rail. In the initial state, the support frame is in a vertical state. At this time, the pin hole on the cross bar is aligned with the pin hole on the slide rail and a pin shaft is inserted. The support frame is fixed in the vertical state through the pin shaft to prevent it from loosening. When it is necessary to perform puncture and catheterization on the patient, the pin shaft is pulled out to release the fixation of the support frame. At this time, the support plate is pulled downward. The support plate rotates around the rotating block at the bottom of the support frame until the long bar and the support plate of the support frame are both in a horizontal state. At this time, the support plate is pushed horizontally towards the bed body. At this time, the rotating block slides in the first chute. When the slider on the long bar enters the second chute, the movement of the support plate is stopped. The horizontal support plate can be stably supported by the rotating block located in the first chute and the slider located in the second chute. After the puncture is completed, the support plate is pulled towards the outside of the bed body. After the slider exits the second chute, the support plate is pushed upward. The support plate rotates upward around the rotating block until the support plate returns to the initial state. When the pin hole on the slide rail is aligned with the pin hole on the cross bar, a pin shaft is inserted into the pin hole to fix the support frame.
[0012] Further, a transverse threaded rod is fixedly connected to the center of the support plate. The threaded rod passes through the central axis of the cross bar and passes out of the cross bar. The threaded rod is rotatably connected to the cross bar. A fastening knob is threadedly connected to the end of the threaded rod passing out of the cross bar. The purpose is that sometimes it is necessary to adjust the position of the arm during puncture and catheterization to find a more suitable puncture vein. Therefore, when it is necessary to adjust the position of the arm, the fastening knob can be rotated to loosen the support plate, and then the support plate is rotated horizontally. The rotation of the support plate drives the arm to rotate to adjust the angle of the arm. After finding the appropriate angle, the fastening knob is rotated in the reverse direction to fix the support plate again.
[0013] Furthermore, four bed legs distributed in a rectangular shape are provided on the lower surface of the bed frame, and the four bed legs are made of lifting rods. The purpose is that during the operation of puncture and catheterization, such as PICC or CVC, doctors usually operate in a standing position because standing operation can provide a better view, facilitate the observation of the patient's overall condition, and also facilitate the doctor's more flexible movement; while when implanting an upper arm port, because this kind of operation requires higher precision and a longer operation time, so doctors may choose to operate in a sitting position. Therefore, the bed legs made of lifting rods can adjust the height of the bed according to the doctor's needs to facilitate the doctor's operation.
[0014] Furthermore, each bed leg includes a fixed rod and a movable rod. The fixed rod is hollow, and a motor is fixedly connected to the inner bottom of the fixed rod. The output shaft of the motor is vertically upward and coaxially fixedly connected to a driving rod. The driving rod is provided with threads. An accommodation cavity is provided in the movable rod, and a threaded through hole is provided at the bottom end of the movable rod. The bottom end of the movable rod is vertically slidably connected in the fixed rod, and the top end of the movable rod is fixedly connected to the bed frame. The driving rod is threadedly connected to the threaded through hole. A control switch for synchronously controlling the forward and reverse rotation of the motors in the four bed legs is provided on the bed frame. When in use, the four motors are synchronously started and rotated forward through the control switch. When the motors rotate forward, the driving rod is driven to rotate by the output shaft. Since the driving rod is provided with threads and the driving rod is threadedly connected to the threaded through hole of the movable rod, when the driving rod rotates, the movable rod is pushed upward in the fixed rod by the threads. When the movable rod moves upward, it lifts the bed frame and then drives the patient on the hospital bed to rise synchronously; similarly, when the motors are controlled to run in reverse through the control switch, the bed frame starts to descend, so as to achieve the purpose of quickly lifting and lowering the hospital bed.
[0015] Furthermore, a self-locking roller is fixedly connected to the bottom end of each fixed rod. The purpose is that through this kind of setting, it is convenient to drive the patient to move through the hospital bed and facilitate the transfer of the patient.
[0016] Furthermore, the bed board includes a front board, a middle board, and a rear board. The front board and the rear board are respectively rotatably connected to both ends of the middle board. Two lifting mechanisms are provided below the bed frame, and the two lifting mechanisms are respectively located directly below the front board and the rear board. The top ends of the two lifting mechanisms are respectively rotatably connected to the lower surfaces of the front board and the rear board. The purpose is that for some patients with kyphosis or ankylosing spondylitis, they cannot lie flat on the hospital bed with their backs straight. Therefore, through this kind of setting, no matter which end of the hospital bed the patient's head lies on, the end of the patient's head can be lifted by the lifting mechanism to form an inclined state, so that patients with kyphosis or ankylosing spondylitis can lie on the hospital bed normally for the operation of puncture and catheterization.
[0017] Further, two slide rails in the same group are fixed by two connecting rods. The slide rails on both sides are slidably connected to the bed frames on both sides, and the sliding direction of the slide rails is the same as the length direction of the bed frames. The purpose is that since the heights of each patient are different and the positions of lying on the bed will also vary, the slide rails are provided to be slidable on the bed frames. The slide rails are pulled to move according to the position of the patient's arm, and then the support frame and the support plate are driven by the slide rails to move near the patient's arm.

[0027] Embodiment 1 is basically as shown in FIGS. Figure 1 ~FIGS. Figure 3 as follows:
[0028] A multi-functional catheterization bed for puncture, comprising a bed body and two arm platforms. The two arm platforms are located on both sides of the bed body. The arm platform includes a support plate 2 and a support frame 5. The support plate 2 is installed at one end of the support frame 5, and the other end of the support frame 5 is rotatably connected to the lower surface of the bed body;
[0029] The bed body includes a bed frame 1 and a bed board 3. The bed board 3 is detachably connected to the bed frame 1. Two slide rails 7 are respectively installed on both sides of the lower surface of the bed frame 1. The two slide rails 7 are perpendicular to the length direction of the bed body. A first chute 10 is provided on one side of the slide rails 7 facing each other. A second chute 11 is provided at the bottom of the first chute 10. The width of the second chute 11 is smaller than the width of the first chute 10, and both the first chute 10 and the second chute 11 extend to the end of the slide rail 7. The support frame 5 is an "L"-shaped support frame 5 composed of a cross bar 501 and a long bar 502. Two cylindrical rotating blocks 9 are rotatably connected to both sides of the bottom end of the support frame 5. The two rotating blocks 9 are respectively slidably connected in the first chutes 10 of the two slide rails 7. Two cylindrical sliders 6 are respectively fixedly connected to both sides of the middle part of the long bar 502. The sliders 6 are used for sliding in the second chutes 11, and the sliders 6 correspond to the second chutes 11 one by one. The cross bar 501 is connected to the support plate 2. A horizontal threaded rod 8 is fixedly connected to the center of the support plate 2. The threaded rod 8 passes through the central axis of the cross bar 501 and passes out of the cross bar 501. The threaded rod 8 is rotatably connected to the cross bar 501. A fastening knob 4 is threadedly connected to the end of the threaded rod 8 passing out of the cross bar 501. A pin hole is provided at the bottom of the long bar 502, and a pin hole is also provided on the slide rail 7.
[0030] The specific implementation process is as follows:
[0031] Before puncture, the patient lies flat on the bed body. At this time, the two support plates 2 are in a vertical state and support on both sides of the bed body. At this time, the support plates 2 act as the guardrails of the bed body to prevent the patient from falling out of the hospital bed to the ground when turning over in the bed, providing safety protection. At this time, the pin holes on the long rod 502 are aligned with the pin holes on the slide rail 7 and are inserted with a pin shaft to fix the support frame 5 in a vertical state to prevent it from loosening. When it is necessary to perform puncture and catheterization on the patient, pull out the pin shaft to release the fixation of the support frame 5. At this time, pull down the support plate 2, and the support plate 2 rotates around the rotating block 9 at the bottom of the support frame 5 until the long rod 502 of the support frame 5 and the support plate 2 are both in a horizontal state. At this time, push the support plate 2 horizontally towards the bed body. At this time, the rotating block 9 slides in the chute 10. When the slider 6 on the long rod 502 enters the chute 11, stop the movement of the support plate 2. Then, the horizontal support plate 2 can be stably supported by the rotating block 9 located in the chute 10 and the slider 6 located in the chute 11. After the puncture is completed, pull the support plate 2 in the direction away from the bed body. After the slider 6 exits the chute 11, push up the support plate 2, and the support plate 2 rotates upward around the rotating block 9 until the support plate 2 returns to the initial state. When the pin holes on the slide rail 7 are aligned with the pin holes on the long rod 502, insert the pin shaft into the pin holes to fix the support frame 5.
[0032] When performing puncture and catheterization, sometimes it is necessary to adjust the position of the arm to find a more suitable puncture vein. Therefore, when it is necessary to adjust the position of the arm, the fastening knob 4 can be rotated to loosen the support plate 2, and then the support plate 2 is rotated horizontally. The rotation of the support plate 2 drives the arm to rotate to adjust the angle of the arm. After finding the appropriate angle, rotate the fastening knob 4 in the reverse direction to fix the support plate 2 again.
[0033] Embodiment 2
[0034] The difference between Embodiment 2 and Embodiment 1 is as shown in the attached Figure 4 : Four bed legs 12 distributed in a rectangular shape are provided on the lower surface of the bed frame 1. The bed legs 12 include a fixed rod 1204 and a movable rod 1201. The fixed rod 1204 is hollow. A motor 1205 is fixedly connected to the inner bottom of the fixed rod 1204. The output shaft of the motor 1205 is vertically upward and coaxially fixedly connected to a driving rod 1203. The driving rod 1203 is provided with a thread. An accommodating cavity 1202 is provided in the movable rod 1201. A threaded through hole is provided at the bottom end of the movable rod 1201. The bottom end of the movable rod 1201 is vertically slidably connected in the fixed rod 1204. The top end of the movable rod 1201 is fixedly connected to the bed frame 1. The driving rod 1203 is threadedly connected to the threaded through hole. A control switch for synchronously controlling the forward and reverse rotation of the motors 1205 in the four bed legs 12 is provided on the bed frame 1. A self-locking roller 1206 is fixedly connected to the bottom end of each fixed rod 1204.
[0035] In use, the four motors 1205 are controlled by a control switch to start synchronously and rotate forward. When the motors 1205 rotate forward, the output shafts drive the drive rods 1203 to rotate. Since the drive rods 1203 are provided with threads and are threadedly connected to the threaded through holes of the moving rods 1201, when the drive rods 1203 rotate, the moving rods 1201 are pushed upward in the fixed rods 1204 through the threads. When the moving rods 1201 move upward, they lift the bed frame 1, thereby driving the patient on the hospital bed to rise synchronously. Similarly, when the motors 1205 are controlled to run in the reverse direction through the control switch, the bed frame 1 starts to descend, so as to achieve the purpose of quickly lifting and lowering the hospital bed.
[0036] Embodiment 3
[0037] The difference between Embodiment 3 and Embodiment 2 is as shown in the appended Figure 5 ~appended Figure 7 : The bed board 3 includes a front board 301, a middle board 302 and a rear board 303. The front board 301 and the rear board 303 are respectively rotatably connected to both ends of the middle board 302. Both ends below the bed frame 1 are respectively fixedly connected with "U"-shaped support rods 13. Lifting mechanisms are fixedly connected to both support rods 13. The two lifting mechanisms are respectively located below the front board 301 and the rear board 303. Taking the lifting mechanism located below the front board 301 as an example, the lifting structure includes a moving block 16 that slides horizontally on the support rod 13. The top end of the moving block 16 is fixedly connected with a moving ring 15. The upper surface of the moving ring 15 is rotatably connected with an inclined top rod 14. The top end of the top rod 14 is rotatably connected to the lower surface of the front board 301. A limiting ring 18 is fixedly connected to the lower surface of the bed frame 1. A rocker 17 is rotatably connected in the limiting ring 18. The rocker 17 is provided with threads. One end of the rocker 17 passes through the moving ring 15 and is threadedly connected to the moving ring 15. The other end of the rocker 17 is fixedly connected with a rotating handle 19.
[0038] Taking the need to raise the front board 301 as an example, rotate the rotating handle 19. The rotating handle 19 drives the rocker 17 to rotate in the limiting ring 18. When the rocker 17 rotates, the moving ring 15 is pushed to move through the threads. When the moving ring 15 moves, the top rod 14 is synchronously pulled, so that the top rod 14 gradually changes from an inclined state to a vertical state. When the top rod 14 changes to a vertical state, the top rod 14 supports the front board 301, so that the front board 301 rotates around the rotation connection with the middle board 302, and the front board 301 changes from a horizontal state to an inclined state. When it is necessary to lower the front board 301, rotate the rotating handle 19 in the reverse direction, and the rocker 17 can rotate in the reverse direction, thereby causing the moving ring 15 to move in the reverse direction, and then driving the top rod 14 to change from a vertical state to an inclined state to lower the front board 301.
[0039] The difference between Example 4 and Example 3 is that: two slide rails 7 in the same group are fixed by two connecting rods, the two sides of the slide rails 7 are slidably connected to the two sides of the bed frame 1, and the sliding direction of the slide rails 7 is the same as the length direction of the bed frame 1. Since the height of each patient is different and the positions of the patients in bed will also vary, the slide rails 7 are provided to be slidable on the bed frame 1. The slide rails 7 are pulled to move according to the position of the patient's arm, and then the support frame 5 and the support plate 2 are driven by the slide rails 7 to move near the patient's arm.
