Description

Technical Field

[0001] The invention relates to medical auxiliary equipment, in particular to an embedded folding ladder based on a protective railing of a medical diagnosis and treatment bed. Background Art

[0002] In the medical field, high-precision examinations such as CT scans, magnetic resonance imaging (MRI), PET-CT, etc., electron accelerators, gamma knife and other radiotherapy equipment usually require patients to lie on the treatment bed, and then adjust the bed to different heights as needed. For example, when performing a CT scan or MRI examination, the medical treatment bed needs to be lowered to the lowest position first so that the patient can lie on it conveniently. Then, according to the requirements of the equipment, the bed will be raised to the corresponding height so that the patient can smoothly enter the CT scanner or MRI equipment for scanning.

[0003] However, in actual operation, the frequent lifting and lowering of the treatment bed has brought considerable burden to medical staff. Especially when facing a large number of patients who need to be examined, medical staff need to repeatedly operate the lifting and lowering buttons of the treatment bed, which not only increases the workload, but also the frequent operation may cause fatigue or even stiffness of the medical staff's fingers, affecting work efficiency. In addition, medical staff also need to repeatedly instruct each patient on how to lie on the treatment bed correctly, including details such as the direction of the head, which not only increases the communication burden of medical staff, but also prolongs the waiting time of patients and reduces the overall diagnosis and treatment efficiency.

[0004] In addition to being a burden on medical staff, frequent operations can also cause wear on the mechanical parts of medical examination equipment, which not only shortens the service life of the equipment, but also increases the risk of equipment failure, thus affecting the continuity of diagnosis and treatment and patient safety. The cost of equipment maintenance and replacement of parts will also bring additional financial burdens to medical institutions.

[0005] In addition, in the process of transferring the patient from the transfer bed to the movable bed surface of the treatment bed, the transfer bed often collides with the bed body, causing damage to the treatment bed. In severe cases, the treatment bed may not be able to operate normally. Summary of the invention

[0006] In order to solve the above technical problems or one of the technical problems, improve the efficiency of diagnosis and treatment, reduce the labor intensity of medical staff, optimize the patient's examination experience, and reduce equipment wear and extend the service life of the equipment, the present invention proposes a guardrail folding ladder based on a medical treatment bed, which aims to simplify the patient's bed-going process through auxiliary equipment, reduce the operating burden of medical staff, improve the efficiency of the diagnosis and treatment process, and reduce the wear rate of equipment.

DETAILED DESCRIPTION

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] As shown in the attached drawings, a medical bed guardrail includes a guardrail 100, which includes two rectangular frames 101, and a front vertical connecting rod 102 and a rear vertical connecting rod 103 are respectively fixed at the empty spaces in front of and behind the medical bed 200, and the two corresponding front vertical connecting rods 102 and rear vertical connecting rods 103 are respectively connected to the front horizontal connecting rod 105 and the rear horizontal connecting rod 106 through pipe clamps 104. In this way, the guardrail 100 can enclose the medical bed in the left, rear and right directions to prevent other moving objects including the transfer bed from hitting the medical bed. At the same time, it will not cause any impact on the original function of the medical bed.

[0041] The pipe clamp 104 can adjust its upper and lower position on the front vertical link 102 and / or the rear vertical link 103. The length of the front cross link 105 and the rear cross link 106 is slightly larger than the bed width of the medical treatment bed 200. Since the medical treatment bed may have different models and sizes, the adjustable pipe clamp enables the guardrail system to adapt to different bed types, increasing the versatility and flexibility of the product. The easy-to-adjust design reduces the workload of medical staff when installing or adjusting the guardrail and improves work efficiency. The length of the front cross link 105 and the rear cross link 106 is slightly larger than the bed width of the medical treatment bed 200, which means that there is a small gap between the guardrail and the treatment bed. When the treatment bed is lifted or other adjustment actions are performed, the small gap between the guardrail and the bed body can avoid interference between the two, ensuring that the function of the treatment bed is not affected. This design of the guardrail can provide better protection for patients, and even when the treatment bed is moving, the patient will not feel uncomfortable or injured due to the contact between the guardrail and the bed body. The guardrail will not hinder any mechanical movement of the treatment bed, such as lifting, tilting, etc., thereby maintaining the integrity and functionality of the bed. The smaller gap can reduce the noise that may be generated when the bed moves, providing a quieter environment for patients and medical staff.

[0042] The length of the frame 101 is slightly smaller than that of the medical bed 200. The upper edge height of the frame 101 is less than 600 mm. The smaller frame length can reduce interference with the movable parts of the bed, such as the lifting, tilting and other actions of the bed, to ensure that the function of the bed is not affected. When the patient moves from the transfer bed to the bed, the smaller frame length can reduce obstacles in the transfer process, making the transfer process smoother. The frame length is slightly smaller than the bed, which can maintain visual coordination and will not appear too abrupt, which helps to improve the overall aesthetics of the medical environment. In some cases, the bed may need to be used in conjunction with other medical equipment such as a mobile X-ray machine, and a shorter frame length can provide more flexibility to adapt to different medical scenarios. The appropriate frame upper edge height makes it more convenient for patients to move from the transfer bed to the bed, especially for patients with limited mobility or who need assistance. When medical staff transfer or examine patients, the appropriate guardrail height enables them to see the patient's status more easily, thereby improving the convenience and efficiency of operation.

[0043] An embedded folding ladder 300 is installed on one of the frames 101, which is located near one end of the diagnosis and treatment equipment. The folding ladder 300 includes a fixed vertical plate 301 fixedly connected to the frame 101, and two guide rails 302 with a stroke in the up-down direction are fixed on the fixed vertical plate 301. Sliders 304 are fixed at the four corners of the movable vertical plate 303, and the slides 304 are slidably matched with the guide rails 302; the inner end of the upper pedal 305 is rotated on the upper circular tube of the frame 101, and the front and rear sides of the upper pedal 305 are respectively connected by two parallel first connecting rods 304. 06 hinged lower pedal 307; the two upper corners of the movable vertical plate 303 are hinged to the middle of the upper pedal 305 through a second connecting rod 308, and the two lower corners of the movable vertical plate 303 are hinged to the inner end of the lower pedal 307 through a third connecting rod 309; it also includes a locking unit, and the locking unit includes a locking tongue 310. When the upper pedal 305 and the lower pedal 307 are in a horizontal state, the locking tongue 310 enters the locking hole 3011 opened in the middle of the fixed vertical plate 301 to lock the upper pedal 305 and the lower pedal 307.

[0044] The specific structure of the locking unit is as follows: The locking tongue 310 comprises a base block 3101, the inner end surface and half of the upper end surface of the base block 3101 extend outwards to form a protrusion 3102, the inner top corner of the protrusion 3102 is beveled to form a contact surface 3103, the inner bottom corner of the protrusion 3102 extends downwards to form a hook 3104, a circular groove 3105 is provided on the right end surface of the protrusion 3102, and a U-groove 3106 with an open upper end surface and a right side surface is provided on the base block 3101, and the groove bottom of the U-groove 3106 has the same radius as the circular groove 3105, and the center of the circle coincides with that of the circular groove 3105; A lock tongue guide hole 3031 is provided at the lower middle portion of the movable vertical plate 303 , and the shape of the lock tongue guide hole 3031 corresponds to the contour of the lock tongue 310 ; The locking unit further comprises: The contact block 311 is fixed on the fixed vertical plate 301 above the locking hole 3011, and a sloped guide surface is provided at one end close to the locking hole 3011, and the sloped guide surface can contact the contact surface 3103; The locking tongue limiting plate 312 has a first limiting hole 3121 in the middle thereof corresponding to the cross-sectional shape of the base block 3101, and the upper end surface of the limiting hole 3121 extends downward to form a stop ear 3122 extending into the U groove 3106; the lower end extends inward to form a bottom plate 3123, and a second elongated limiting hole 3124 is formed in the middle of the bottom plate 3123; The spring 313 is placed in the circular groove 3105 and the U groove 3106, with one end abutting against the bottom of the circular groove 3105 and the other end abutting against the stop ear 3122; The T-shaped plate 314 includes a horizontal bar portion 3141 and a vertical bar portion 3143. The upper section of the vertical bar portion 3143 extends to both sides to form an enlarged portion 3142. The enlarged portion 3142 defines a third limiting hole 3144. The lower portion 31441 of the third limiting hole corresponds to the cross-sectional shape of the base block 3101. The width of the upper portion 31442 of the third limiting hole is greater than the width of the protrusion 3102 and less than the width of the base block 3101. The vertical bar portion 3143 enters the second limiting hole 3124. Two tension springs 315, the upper ends of which are respectively connected to the two ends of the horizontal strip 3141, and the lower ends of which are respectively connected to the two ends of the bottom plate 3123; The four guide wheels 316 are respectively rotated on the inner surface of the movable vertical plate 303 on both sides of the lock tongue guide hole 3031, with the axial direction being the left and right direction, and an annular groove is provided on the circumferential circular surface, and the enlarged part 3142 enters the annular groove.

[0045] A handle hole 3051 for four fingers to be inserted is provided in the middle of the outer end of the upper pedal 305 , and a handle sleeve 319 is fixedly arranged on the lower surface of the upper pedal 305 corresponding to the handle hole 3051 .

[0046] Assume that the initial state is Fig.11As shown, the upper pedal 305 and the lower pedal 307 are both in a retracted state, at which time the protrusion 3102 of the locking tongue 310 passes through the locking hole 3011 of the movable vertical plate 303 and the lower part 31441 of the third limiting hole of the T-shaped plate 314, and the inner end surface of the protrusion 3102 abuts against the inner surface of the fixed vertical plate 301 under the action of the spring 313. At this time, the folding ladder 300 is very small and will not affect the surrounding people and equipment. When encountering an elderly or weak patient who has difficulty climbing onto the treatment bed 200, the operator can reach into the handle hole 3051 provided on the upper pedal 305 and pull up the upper pedal 305. When the upper pedal 305 flips upward, it also drives the lower pedal 307 to flip upward synchronously, and at the same time drives the movable vertical plate 303 to move upward linearly relative to the fixed vertical plate 301. When the upper pedal 305 flips upward to a state slightly greater than the horizontal state, the protrusion 3102 of the locking tongue 310 reaches the locking hole 3011 provided in the middle of the fixed vertical plate 301 and enters it. At this time, the operator flips the upper pedal 305 downward slightly, and the hook head 3104 of the locking tongue 310 hooks on the lower edge of the locking hole 3011, and the upper pedal 305 and the lower pedal 307 are both in a horizontal state. Fig.12 As shown, since the hook 3104 of the lock tongue 310 is hooked on the lower side of the lock hole 3011, the upper pedal 305 or the lower pedal 307 will not sink when stepped on. It is convenient for the elderly or the weak to climb onto the diagnosis and treatment bed 200. Since the folding ladder 300 is close to one end of the diagnosis and treatment equipment, after the patient climbs up, the head naturally faces one side of the diagnosis and treatment equipment, and the medical staff no longer need to give cumbersome instructions and guidance to each patient.

[0047] When the upper pedal 305 and the lower pedal 307 are no longer needed, the operator again reaches into the handle hole 3051 provided on the upper pedal 305 to pull up the upper pedal 305. When the upper pedal 305 flips upward, it also drives the movable vertical plate 303 to continue to move linearly upward relative to the fixed vertical plate 301. First, the hook head 3104 of the lock tongue 310 disengages from the lower edge of the lock hole 3011, and then the contact surface 3103 of the protrusion 3102 of the lock tongue 310 contacts the sloped guide surface of the contact block 311, forcing the lock tongue 310 to move outward. At this time, under the action of the two tension springs 315, the T-shaped plate 314 moves downward relative to the movable vertical plate 303, and the upper portion 31442 of the third limiting hole blocks the inner end surface of the base block 3101 of the lock tongue 310, so that the lock tongue 310 can no longer move inward. At this time, the operator presses down the upper pedal 305, and the upper pedal 305 flips downward while driving the lower pedal 307 to flip downward synchronously, and also driving the movable vertical plate 303 to move linearly downward relative to the fixed vertical plate 301. Since the locking tongue 310 can no longer move inward, even if it descends to the locking hole 3011 opened in the middle of the fixed vertical plate 301, the locking tongue 310 will not enter and lock. In this way, until the vertical bar 3143 of the T-shaped plate 314 contacts the ground or the bottom plate 3012 formed by the lower end of the fixed vertical plate 301 extending outward, the T-shaped plate 314 moves upward relative to the movable vertical plate 303, and the upper portion 31442 of the third limiting hole no longer blocks the inner end surface of the base block 3101 of the locking tongue 310. The base block 3101 of the locking tongue 310 enters the lower portion 31441 of the third limiting hole of the T-shaped plate 314, so that the inner end surface of the protrusion 3102 of the locking tongue 310 abuts against the inner surface of the fixed vertical plate 301 under the action of the spring 313 to return to the initial state, ready for the next round of operation.

[0048] The design of the embedded folding ladder 300 of this embodiment has the following excellent technical effects: 1. Improved convenience: Patients can easily climb onto the treatment bed via the folding ladder, which provides great convenience especially for patients with limited mobility, such as the elderly or the weak.

[0049] 2. Reduce the burden on medical staff: Through automated auxiliary equipment, the physical labor of medical staff in helping patients get in and out of bed is reduced, and the work intensity is reduced.

In summary, the design of the folding ladder 300 in Example 3 not only improves the auxiliary function of the medical treatment bed, but also brings practical convenience and safety protection to patients and medical staff through its innovative structure and operation mode.

[0061] In another preferred embodiment, a pin 317 with an axial direction in the front-to-back direction is provided on the protrusion 3102, and rollers 318 are provided on the pins 317 on both sides of the protrusion 3102; the width of the upper portion 31442 of the third limiting hole is greater than the length of the pin 317. The design of providing the pin 317 and the roller 318 on the protrusion 3102 is mainly to convert sliding friction into rolling friction, and the following are the excellent technical effects brought by this design: 1. Reduce friction: The rolling contact of the roller 318 replaces the traditional sliding friction, which significantly reduces the friction between the protrusion 3102 and the fixed vertical plate 301, which helps to improve the smoothness of the unfolding and folding of the folding ladder 300.

[0062] 2. Reduce noise: Compared with sliding friction, rolling friction can significantly reduce noise during operation, providing a quieter medical environment for patients and medical staff.

[0063] 3. Improved durability: Reduced friction means less wear on the bumps 3102 and the fixed riser 301, thereby improving the durability and service life of the components.

[0064] 4. Smooth operation: Rolling friction makes the operation smoother, reduces the force required by the operator when unfolding or folding the folding ladder, and improves the user experience.

[0065] 5. Easy maintenance: Due to reduced wear and tear, related maintenance work will also be reduced accordingly, reducing maintenance costs and workload.

[0066] 6. Improved response speed: The rolling friction makes the action of the locking tongue 310 more rapid and accurate, thereby improving the response speed and use efficiency of the folding ladder 300.

[0067] 7. Enhanced stability: The roller 318 provides a more stable contact method, making the lock tongue 310 more stable during the locking and unlocking process, reducing the risk of accidental unlocking.

[0068] 8. Optimized design: This design optimizes the structure of the folding ladder, making the entire system more compact and efficient.

[0069] 9. Strong adaptability: The improved rolling friction mechanism enables the Folding Ladder 300 to adapt to a wider range of usage environments and conditions, including frequent use or extreme environments.

[0070] 10. Improved overall performance: By reducing friction and noise, the overall performance of the folding ladder 300 is improved, making it more reliable and efficient.

[0071] In another preferred embodiment, damping rods 320 are respectively installed on the bottom plate 3123 on both sides of the second limiting hole 3124. The damping rod 320 can provide a steady resistance, so that the unfolding and folding actions of the folding ladder 300 are smoother, reducing impact and vibration. The damping rod 320 helps to reduce the noise generated when the folding ladder moves, providing a quieter use environment. The damping rod 320 can prevent the folding ladder from moving suddenly and quickly during the unfolding or folding process, thereby reducing the risk of the user's hand being pinched. The damping rod 320 can control the unfolding and folding speed of the folding ladder, avoid injuries caused by rapid movements, and improve the safety of use. The damping rod 320 helps to maintain stability when the folding ladder is unfolded, reducing accidental folding caused by accidental collisions or unstable operations. The damping rod 320 helps to extend the service life of the folding ladder and its components by reducing the impact and wear of the folding ladder.

[0072] In another preferred embodiment, the lower end of the fixed vertical plate 301 extends outward to form a bottom plate 3012, and the bottom plate 3012 abuts against the ground to replace one of the support rods 107. By replacing the support rod 107 with the bottom plate 3012, the overall structure is simplified, the number of components is reduced, and the folding ladder 300 is more concise. The direct contact between the bottom plate 3012 and the ground provides an additional support point, which enhances the stability of the folding ladder 300 when in use. The bottom plate 3012 provides a fixed point, so that the folding ladder 300 can adapt to different ground conditions, including uneven ground.
