Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a drainage bag hanging height-adjustable hospital bed. Background Art

[0002] Clinically, some patients need drainage after surgery to discharge the contents of the body cavities to promote early healing of the body, such as ventricular drainage, abdominal drainage and chest drainage. At present, the beds used in hospitals lack drainage bag hanging mechanisms. Therefore, in actual work, nurses usually use straps or tapes to tie the drainage bag and hang it on the bed rails or bedside. However, there are problems with this operation: 1) The drainage bag has a poor fixing effect, and as the drainage fluid increases, the drainage bag is prone to fall; 2) It is more troublesome to adjust the height position of the drainage bag. In this way, when discharging the drainage fluid in the drainage bag, the patient's family usually lifts the basin with one hand and turns on the switch on the drainage bag with the other hand. One-handed operation is more dangerous, and the basin is easily overturned when it is empty. This causes the drainage fluid to spill on the floor of the ward; in addition, some drainage procedures have special requirements for the position of the drainage bag. For example, during ventricular drainage, the drainage bag cannot be placed below the patient's head. It is generally required that the drainage bag be 10-15 cm higher than the patient's head to maintain intracranial pressure stability. In this way, when the patient adjusts the height of the bed head according to the condition, the drainage bag also needs to be adjusted so that the height of the drainage bag is always 10-15 cm higher than the patient's head. However, the drainage bag is fixed to the bed rail or bed head with a strap or tape, which is difficult to operate and time-consuming and laborious. Therefore, it is necessary to design a hospital bed that can adjust the hanging height of the drainage bag. Summary of the invention

[0003] The present invention is intended to provide a hospital bed with adjustable drainage bag hanging height, so as to solve the problem that the height position of the drainage bag is difficult to adjust.

[0004] In order to achieve the above-mentioned purpose, the scheme of the present invention is: a drainage bag hanging height adjustable bed, including a bed body, a suspension component for hanging the drainage bag is installed on the bed body, the suspension component includes a mounting block, a bracket, a lifting plate and a ball screw pair, the side wall of the bed body is provided with a horizontally arranged T-slot, the mounting block is fixedly connected with a T-block that slides with the T-slot, the bracket is rotatably connected to the mounting block, and the mounting block is provided with a locking component for locking the bracket, the ball screw pair includes a screw and a nut, the two ends of the screw are respectively rotatably connected to the bracket, the nut is slidably connected to the bracket along the length direction of the bracket, the lifting plate is fixedly connected to the nut, and a hook for hanging the drainage bag is provided on the lifting plate.

[0005] The working principle and beneficial effect of this scheme are as follows: in this scheme, the mounting block is horizontally slidably connected to the bed body, so that the suspension assembly can be located at the head of the bed, the middle of the bed or the foot of the bed according to the actual situation, so as to adapt to the drainage position of the patient. Secondly, in this scheme, the height of the lifting plate is adjusted by using a ball screw pair to adjust the height of the lifting plate, so as to adjust the suspension height of the drainage bag, and the suspension height of the drainage bag can be adjusted by simply turning the screw, which is easy to operate. In this way, the height of the drainage bag can be quickly lowered so that the basin can be placed on the floor of the ward for drainage, and the height position of the drainage bag can also be quickly adjusted in accordance with the patient's head position during the patient's ventricular drainage process. In addition, in this scheme, the bracket is rotatably connected to the mounting block, and the bracket is locked by a locking assembly, so that the bracket can remain vertical relative to the ground when the head of the bed body of the bed is tilted, so as to avoid the bracket from tilting relative to the ground, thereby avoiding the bracket and the drainage bag from affecting the sight of the patient, the patient's family members and medical staff.

[0006] Optionally, the bracket is fixedly connected to a roller, a bearing is fixedly mounted on the mounting block, and the roller is coaxially connected to the bearing; the locking assembly includes a ring and a locking roller, the ring is fixedly connected to the mounting block, the locking roller is connected to the ring along a radial thread of the ring, a rubber pad is provided at one end of the locking roller located inside the ring, and a gear portion is coaxially provided on the roller.

[0007] In this solution, the locking roller can move radially along the ring, so that the rubber cushion layer is tightly pressed against the gear part on the roller, thereby locking the roller and preventing the roller from rotating. In this way, the bracket can be prevented from rotating and the bracket can be locked.

[0008] Optionally, a horizontal threaded hole is provided on the mounting block, the horizontal threaded hole extends into the T-block, a clamping screw is threadedly connected to the horizontal threaded hole, and the clamping screw can be abutted against the groove wall of the T-slot.

[0009] In this solution, after the tightening screw is rotated, it is pressed against the groove wall of the T-slot, so that the T-block is subjected to a reverse force, thereby fixing the T-block, preventing the T-block from sliding freely in the T-slot, and avoiding the movement of the drainage bag and involving the drainage tube.

[0010] Optionally, the hook includes a U-shaped hook body, an extension plate and a snap-fit ​​plate, one end of the extension plate is fixedly connected to the U-shaped hook body, the other end of the extension plate is connected to the lifting plate, a positioning column is fixedly connected to the extension plate, a locking piece is threadedly connected to the positioning column, a through hole is provided on the snap-fit ​​plate for the positioning column to pass through, and the snap-fit ​​plate can cover the open end of the U-shaped hook body.

[0011] In this solution, the opening end of the U-shaped hook body is covered by a buckling plate, thereby preventing the drainage bag from being separated from the U-shaped hook body and improving the suspension stability of the drainage bag.

[0012] Optionally, the buckling plate is provided with a lock hole for the end of the U-shaped hook body away from the extension plate to pass through.

[0013] In this solution, after the drainage bag is hung on the U-shaped hook body, the snap plate covers the open end of the U-shaped hook body, and there is no gap between the snap plate and the U-shaped hook body for the drainage bag to be detached, which is safer.

[0014] Optionally, a driving motor for driving the lead screw to rotate forward and reverse is fixedly mounted on the bracket.

[0015] In this solution, a driving motor is used to drive the lead screw to rotate forward and reverse, thereby realizing the lifting and lowering movement of the nut, and then realizing the adjustment of the suspension height of the drainage bag, avoiding manual rotation of the lead screw.

[0016] Optionally, the drive motor is electrically connected to a switch for controlling the start and stop of the drive motor, and the switch is electrically connected to the drive motor through an electric wire.

[0017] In this solution, the switch that controls the opening and closing of the drive motor can be located on the bed. When the patient is alone, the switch can be used to control the drive motor to work, so that the drainage bag rises for the patient to check the amount of drainage fluid in the drainage bag, so that the patient can call the nurse in time to help him drain the drainage fluid.

[0018] Optionally, the hook is hinged to the lifting plate, and a diagonal support rod is fixedly connected to the hook. A force plate is fixedly connected to the end of the diagonal support rod away from the hook. The force plate can fit with the lifting plate. A pressure sensor is provided on the side wall of the force plate facing the lifting plate. A warning piece and a controller are fixedly installed on the bracket. The pressure sensor and the warning piece are electrically connected to the controller. The controller controls the operation of the warning piece according to the pressure information detected by the pressure sensor.

[0019] In this solution, after the drainage bag is hung on the hook, as the amount of drainage fluid in the bag increases, the weight of the drainage bag gradually increases, the force applied to the hook gradually increases, and the pressure detected by the pressure sensor between the force plate and the lifting plate gradually increases. When the amount of drainage fluid in the drainage bag reaches the upper limit, the controller controls the alarm component to operate to alert the patient and the patient's family that the drainage fluid in the drainage bag needs to be discharged, thereby avoiding the patient and the patient's family from checking the condition of the drainage bag all the time.

[0020] Optionally, the warning element is a buzzer.

[0021] In this solution, when the warning element is a buzzer, the buzzing sound emitted by the buzzer can attract the attention of the patient, the patient's family members and the nurse, thereby playing a warning role.

[0022] Optionally, there are two locking rollers in the locking assembly, and the two locking rollers are arranged opposite to each other.

[0023] In this solution, the locking roller locks the bracket from two opposite directions, and the locking effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 1

[0033] This embodiment is basically Figure 1 , Figure 2 and Figure 3As shown: A drainage bag hanging height adjustable hospital bed, including a hospital bed body 1, a suspension assembly for hanging a drainage bag is installed on the hospital bed body 1, and the suspension assembly includes a mounting block 2, a bracket 3, a lifting plate 4 and a ball screw pair, wherein the mounting block 2 is horizontally slidably connected to the hospital bed body 1, specifically, a horizontally arranged T-slot 101 is provided on the side wall of the hospital bed body 1, and a T-block 5 slidably matched with the T-slot 101 is welded to the mounting block 2. In addition, a horizontal threaded hole is provided on the mounting block 2, and the horizontal threaded hole extends into the T-block 5, and a tightening screw 6 is threadedly connected to the horizontal threaded hole, and the tightening screw 6 can be abutted against the groove wall of the T-slot 101.

[0034] The bracket 3 is rotatably connected to the mounting block 2. Specifically, Figure 4 As shown, a roller 7 is welded on the bracket 3, a bearing 8 is fixedly mounted on the mounting block 2, and the roller 7 is coaxially connected to the bearing 8, so as to realize the rotation connection between the bracket 3 and the mounting block 2. A locking assembly for locking the bracket 3 is provided on the mounting block 2, and the locking assembly includes a ring 9 and a locking roller 10. The ring 9 is welded to the mounting block 2, and the locking roller 10 is threadedly connected to the ring 9 along the radial direction of the ring 9. A rubber cushion layer 11 is bonded to one end of the locking roller 10 located inside the ring 9, and a gear part 12 is coaxially provided on the roller 7, so that the rubber cushion layer 11 is used to press against the gear part 12 to realize the locking of the roller 7, and then the locking of the bracket 3 is realized. In addition, in this embodiment, there are two locking rollers 10 in the locking assembly, and the two locking rollers 10 are arranged opposite to each other, and the axial direction of the locking roller 10 is perpendicular to the length direction of the bracket 3.

[0035] The ball screw pair includes a lead screw 13 and a nut 14. The two ends of the lead screw 13 are rotatably connected to the bracket 3. Specifically, the two ends of the lead screw 13 are rotatably connected to the bracket 3 through bearings 8. The nut 14 is slidably connected to the bracket 3 along the length direction of the bracket 3. Specifically, the bracket 3 is provided with a vertical slide groove 301 along its length direction. The nut 14 is welded with a vertical slider 15 that slides with the vertical slide groove 301. The lifting plate 4 is welded with the nut 14, and the lifting plate 4 is provided with a hook 16 for hanging the drainage bag. In addition, a driving motor 17 for driving the lead screw 13 to rotate forward and reverse is fixedly installed on the bracket 3. The driving motor 17 is electrically connected to a switch 18 for controlling the opening and closing of the driving motor 17 through electric wires.

[0036] During actual use, according to the drainage site of the patient, push the mounting block 2 to slide horizontally until the mounting block 2 moves to a suitable position, then rotate the tightening screw 6 so that the tightening screw 6 is pressed against the groove wall of the T-slot 101, and the T-block 5 is subjected to a reverse force and pressed against the groove wall of the T-slot 101, thereby fixing the mounting block 2 and preventing the suspension assembly from moving at will.

[0037] Next, the switch 18 controls the driving motor 17 to work, and the driving motor 17 drives the lead screw 13 to rotate forward or reverse, thereby driving the nut 14 to rise and fall along the lead screw 13, thereby realizing the lifting and lowering of the lifting plate 4, until the hook 16 on the lifting plate 4 moves to a suitable height. Then, the nurse hangs the drainage bag on the hook 16.

[0038] During the drainage process, when the drainage fluid in the drainage bag needs to be discharged, the switch 18 is used to control the drive motor 17 to work, the drive motor 17 drives the lead screw 13 to reverse, the nut 14 drives the lifting plate 4 to descend, and the drainage bag descends until the discharge port of the drainage bag is close to the basin placed on the ground. At this time, the patient's family can open the discharge switch on the drainage bag to discharge the drainage fluid without lifting the basin, which effectively prevents the basin from tipping over. The patient's family can fix the drainage bag with one hand and control the discharge switch of the drainage bag with the other hand, which has a higher safety factor. After the drainage fluid is discharged, the discharge switch of the drainage bag is closed, and the switch 18 is used to control the drive motor 17 to work again. The drive motor 17 drives the lead screw 13 to rotate forward, and the nut 14 drives the lifting plate 4 to rise and reset, thereby realizing the rise and reset of the drainage bag.

[0039] Furthermore, during the drainage process, when the patient has no family members or nursing staff to accompany him, the patient can control the drive motor 17 through the switch 18 to make the drainage bag rise, so that the patient can observe the amount of drainage fluid in the drainage bag while lying flat on the bed, and call the nurse in time when the drainage fluid is large, so as to avoid the patient getting up to check, thereby avoiding the patient pulling the wound and causing pain.

[0040] In addition, in this embodiment, if the patient is undergoing ventricular drainage, the suspension assembly is moved to the head of the bed body 1, and the height of the lifting plate 4 is adjusted by the drive motor 17 and the ball screw pair, so that when the drainage bag is hung on the hook 16, the drainage bag is 10-15 cm higher than the patient's head. During the drainage process, when adjusting the height of the head of the bed (the bed body 1 in this embodiment is a single-crank bed), the height position of the drainage bag is adjusted at the same time. Specifically, the locking assembly is first unlocked from the bracket 3. Since the drive motor 17 is located at the bottom end of the bracket 3, it is equivalent to having a counterweight at the bottom end of the bracket 3. Therefore, the bracket 3 is likely to remain in a vertical state. Further, to ensure that the bracket 3 does not rotate freely to a large extent, the nurse or the patient's family member holds the bracket 3 by hand after unlocking the bracket 3. In this way, during the adjustment process of the head of the bed body 1, the bracket 3 can always remain in a vertical state, and the height adjustment of the drainage bag is achieved by the drive motor 17 and the ball screw pair, ensuring that the height of the drainage bag is always 10-15 cm higher than the patient's head, which is convenient to operate. After the height adjustment of the bedside is completed, the locking roller 10 is rotated so that the locking roller 10 is pressed against the gear portion 12 of the rotating roller 7 again, thereby restoring the locking of the bracket 3 .

[0041] In summary, in this embodiment, the position of the suspension assembly can be adjusted according to the drainage site of the patient, and the height and position of the drainage bag can be adjusted during the drainage process, which is particularly suitable for patients with ventricular drainage.

[0042] Embodiment 2

[0043] The difference between this embodiment and the first embodiment is that: Figure 5 and Figure 6 As shown, the hook 16 in this embodiment adopts a special structure. Specifically, the hook 16 in this embodiment includes a U-shaped hook body 161, an extension plate 162 and a buckle plate 163. One end of the extension plate 162 is welded to the U-shaped hook body 161, and the other end of the extension plate 162 is hinged to the lifting plate 4 through a hinge 19. A positioning column 20 is welded on the extension plate 162, and a locking member 21 is threadedly connected to the positioning column 20. In this embodiment, the locking member 21 is an ordinary nut. A through hole is provided on the buckle plate 163 for the positioning column 20 to pass through. The buckle plate 163 can cover the open end of the U-shaped hook body 161, and the buckle plate 163 is also provided with a locking hole for the end of the U-shaped hook body 161 away from the extension plate 162 to pass through.

[0044] The extension plate 162 is welded with an oblique support rod 22, and a force plate 23 is welded at one end of the oblique support rod 22 away from the extension plate 162. The force plate 23 can fit with the lifting plate 4. A pressure sensor 24 is bonded to one side wall of the force plate 23 facing the lifting plate 4. The pressure sensor 24 is located between the force plate 23 and the lifting plate 4. A warning member 25 and a controller 26 are bonded to the bracket 3. The pressure sensor 24 and the warning member 25 are both electrically connected to the controller 26. The controller 26 controls the warning member 25 to work according to the pressure information detected by the pressure sensor 24. In this embodiment, the warning member 25 is a buzzer.

[0045] In this embodiment, the locking member 21 on the positioning column 20 does not lock the snap plate 163. At this time, the end of the U-shaped hook body 161 can be separated from the lock hole on the snap plate 163. After the drainage bag is hung on the U-shaped hook body 161, the lock hole on the snap plate 163 passes through the corresponding end of the U-shaped hook body 161, and the snap plate 163 covers the open end of the U-shaped hook body 161. The locking member 21 is rotated to make the snap plate 163 close to the extension plate 162 to achieve the sealing of the U-shaped hook body 161 and prevent the drainage bag from being unhooked. Moreover, in this embodiment, during the drainage process, the pressure information detected by the pressure sensor 24 can reflect the amount of drainage fluid in the drainage bag. When the drainage fluid in the drainage bag reaches the upper limit, the pressure information detected by the pressure sensor 24 reaches the threshold value, and the controller 26 controls the warning member 25 to work and emit a buzzer to warn the patient, the patient's family members and other personnel, and remind the patient, the patient's family members and other personnel to discharge the drainage fluid in time to avoid forgetting to discharge the drainage fluid.
