Description

Technical Field

[0001] This utility model relates to the field of medical beds, and in particular to a medical bed guardrail with an anti-tripping function. Background Technology

[0002] A medical bed is a common type of bed. Its bed board, bed frame, and wheels can all be manually operated, which makes it convenient for medical staff to adjust the height and angle of the bed. In order to facilitate patients to enter or leave the bed, the guardrails of the medical bed are usually movable. By lowering the guardrails, it is convenient for the operator to get out of bed and move around.

[0003] In existing medical bed rails, protrusions at both ends are commonly used to improve coverage. While these protrusions increase the coverage area, they can restrict patient movement when the rail is retracted. Furthermore, when patients get out of bed, these protrusions can easily snag on their trouser legs, causing them to fall. Moreover, most existing medical bed rails only lock when raised; if the protrusions snag on the patient's trouser legs, continued movement will cause the rail to rotate, further increasing the probability of a fall. The entire device poses a risk of tripping during use. Therefore, a medical bed rail with anti-tripping functionality is proposed to address these problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a medical bed rail with an anti-tripping function, which aims to improve the problem that "the existing medical bed rail has defects in use, which will increase the risk of the device tripping the patient".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a medical bed rail with anti-tripping function, comprising a fixed frame, a support rod hinged to the upper surface of the fixed frame, a hinge seat hinged to the upper surface of the support rod, a guardrail fixedly connected to the outer wall of the hinge seat, a blocking component provided on the inner wall of the guardrail, the blocking component comprising a blocking rod inserted into the inner wall of the guardrail, a rotating shaft fixedly connected to the outer wall of the support rod, the rotating shaft passing through and rotatably connected to the front surface of the hinge seat, a transmission wheel fixedly connected to the outer wall of the rotating shaft, a rack meshing with the transmission wheel fixedly connected to the end of the blocking rod near the transmission wheel, a fixing component provided on the outer wall of the support rod, the fixing component comprising a plug rod passing through and slidably connected to the lower surface of the support rod, a first slot provided on the upper surface of the fixed frame, and a second slot obliquely provided on the inner wall of the fixed frame.

[0006] As a further description of the above technical solution:

[0007] The fixing assembly also includes a support plate, which is fixedly connected to the upper end of the insertion rod. The upper surface of the support plate is elastically connected to the inner wall of the support rod by a fixing spring.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by setting a movable blocking component, during the process of the support rod rotating to the tilting state, the support rod will drive the rotating shaft to rotate, and the rotating shaft will drive the transmission wheel to rotate. In this way, the two sets of blocking rods can be pulled into the guardrail. At the same time, after the support rod is tilted, the insert rod can be inserted into the second slot to fix the whole device in the tilting state. This setting can reduce the probability of the device catching the patient's trouser leg, and at the same time prevent the device from moving further after catching the patient's trouser leg. The overall device has good safety.

[0022] 2. In this utility model, by setting a locking component, when the patient is in a state such as sleeping and does not need to get out of bed, the locking plate can be inserted into the middle position of the unlocking block. At this time, the unlocking block will be restricted and cannot be pressed down. This can prevent the patient from unlocking the entire device unconsciously, and can further improve the safety of the device. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a medical bed rail with anti-tripping function, including a fixed frame 1 for supporting the overall device. A support rod 2 for supporting the rotation of a hinge seat 8 is hinged to the upper surface of the fixed frame 1. A hinge seat 8 for supporting a guardrail 3 is hinged to the upper surface of the support rod 2. A guardrail 3 for blocking patient movement is fixedly connected to the outer wall of the hinge seat 8. A blocking component 4 for increasing the coverage area of ​​the guardrail 3 is provided on the inner wall of the guardrail 3. The blocking component 4 includes a blocking bar 41 for directly blocking the patient. The blocking bar 41 is inserted into the inner wall of the guardrail 3 and is a U-shaped hollow bar, which can be inserted to the left or right inside the blocking bar 41. Moving to the right, the outer wall of the support rod 2 is fixedly connected to a rotating shaft 45 for driving the transmission wheel 42 to rotate. The rotating shaft 45 passes through and is rotatably connected to the front surface of the hinge seat 8. The outer wall of the rotating shaft 45 is fixedly connected to a transmission wheel 42 for transmitting power. The end of the barrier bar 41 near the transmission wheel 42 is fixedly connected to a rack 43 that meshes with the transmission wheel 42. When the support rod 2 rotates downward and tilts, it will drive the transmission wheel 42 to rotate through the rotating shaft 45. This will drive the rack 43 to move into the guardrail 3. The rack 43 will drive the barrier bar 41 to move into the guardrail 3. The outer wall of the support rod 2 is provided with a fixing component 5 for fixing the tilt angle of the support rod 2.

[0032] Reference Figure 1 - Figure 3 The fixing component 5 includes a plug rod 53, which passes through and is slidably connected to the lower surface of the support rod 2. The plug rod 53 can move up and down on the inner wall of the support rod 2. The upper surface of the fixing frame 1 is provided with a first slot 51 for accommodating the plug rod 53. The inner wall of the fixing frame 1 is provided with a second slot 52 at an angle. When the support rod 2 is in a vertical state, the plug rod 53 can move downward and insert into the interior of the first slot 51. When the support rod 2 is in a tilted state, the plug rod 53 can move obliquely to the lower left and insert into the interior of the second slot 52. In this way, the support rod 2 can also be fixed.

[0033] Reference Figure 2 - Figure 4The fixing component 5 also includes a support plate 54 for moving the insertion rod 53. The support plate 54 is fixedly connected to the upper end of the insertion rod 53. When the support plate 54 moves up and down, the insertion rod 53 will be moved synchronously. The upper surface of the support plate 54 is elastically connected to the inner wall of the support rod 2 through a fixing spring 55. The fixing spring 55 will support the support plate 54 downward at all times. The front and rear surfaces of the support plate 54 are fixedly connected to cylindrical blocks 57 for moving the support plate 54. The left end of the support rod 2 is slidably connected to an unlocking block 56 for pressing the cylindrical block 57. The right surface of the unlocking block 56 is set in an inclined shape. By pressing the unlocking block 56, the unlocking block 56 can be driven to press the cylindrical block 57, thus driving the cylindrical block 57 to move upward. The upward movement of the cylindrical block 57 can drive the insertion rod 53 to move upward. The unlocking block 56 is set in a U-shape. The inner wall of the unlocking block 56 is provided with a locking component 6 for restricting the movement of the unlocking block 56.

[0034] Reference Figure 2 - Figure 4 The locking assembly 6 includes a locking plate 61 for blocking the movement of the unlocking block 56. The locking plate 61 is inserted into the inner wall of the unlocking block 56. When the locking plate 61 is inside the unlocking block 56, the unlocking block 56 will be restricted from moving into the support rod 2. The outer wall of the locking plate 61 is fixedly connected to a rubber block 63 for preventing the locking plate 61 from moving arbitrarily. The inner wall of the unlocking block 56 is provided with a positioning groove 64 that matches the rubber block 63. When the rubber block 63 is inserted into the positioning groove 64, the locking plate 61 will be restricted from moving arbitrarily. The upper surface of the locking plate 61 is fixedly connected to a limiting plate 62 for limiting the insertion depth of the locking plate 61. The front surface of the locking plate 61 is provided with a locking hole 65 for locking the locking plate 61. The end of the barrier rod 41 away from the guardrail 3 is fixedly connected to a rubber head 44 for protecting the patient. By setting the rubber head 44, the injury to the patient when hitting the device can be reduced. The front surface of the fixing frame 1 is provided with a mounting hole 7.

[0035] Working principle: When it is necessary to lower the guardrail to facilitate the patient's movement, first press the unlocking block 56. Since the right surface of the unlocking block 56 is inclined, it will move to the left and squeeze the cylindrical block 57 when pressed. The cylindrical block 57 drives the support plate 54 to move upward against the elastic force of the fixing spring 55, thereby causing the insertion rod 53 to be pulled out from the first slot 51. Then, the support rod 2 is rotated downward and tilted. During the rotation of the support rod 2, the rotating shaft 45 is driven to rotate. The rotating shaft 45 drives the transmission wheel 42 to rotate. The rack 43 meshing with the transmission wheel 42 will drive the blocking rod 41 to move into the guardrail 3 until it is completely retracted into the guardrail 3. When the entire device is rotated to the tilted state, the unlocking block 56 can be released. In this way, the insertion rod 53 will move diagonally to the lower left under the action of the fixing spring 55 and insert into the second slot 52, fixing the support rod 2 in the tilted state, thereby preventing the retracted guardrail from catching on the patient's trouser leg and reducing the risk of the patient tripping.

[0036] When the patient does not need to get out of bed, such as when they are asleep, to prevent the patient from unconsciously unlocking the guardrail, the locking component 6 can be used. The locking plate 61 is inserted into the inner wall of the unlocking block 56. The rubber block 63 on the outer wall of the locking plate 61 will be engaged in the positioning groove 64 on the inner wall of the unlocking block 56, thus fixing the locking plate 61. At the same time, the limiting plate 62 can limit the insertion depth of the locking plate 61. After the locking plate 61 is inserted, the unlocking block 56 is restricted from moving into the support rod 2, and therefore cannot be pressed to disengage the insertion rod 53 from the slot. This prevents the patient from unconsciously unlocking the entire device and further improves the safety of the device.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
