Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and in particular to an examination bed for neurology. Background Art

[0002] The symptoms of neurological diseases vary, but usually involve dysfunction of the nervous system, which may directly or indirectly affect the patient's ability to move and conscious expression. Therefore, during the examination of neurological patients, medical staff often need to pay special attention to the patient's movement safety and take corresponding measures to reduce the patient's movement burden, which also makes it inconvenient to move the patient during the examination. In neurological examinations, neurological physical examinations are an indispensable part, which involves a series of neurological reflex tests, including neurological reflex tests of the upper and lower limbs. The transition between lying and sitting postures is more conducive to the examination. However, traditional examination beds often have a single function and cannot adjust the patient's position.

[0003] In response to the above problems, patent number CN113081629B discloses a neurology auxiliary examination bed, which can lift the patient's knee to a certain position by providing a flip mechanism between the first support frame, so that medical staff can check the knee jerk reaction. However, the patent still has the following problems: 1. It is difficult to examine the patient in a sitting position. The patented flip mechanism can be electrically controlled to lift the knee, which is convenient for knee jerk reflex testing, but it cannot convert the patient from a supine position to a sitting position, nor can it easily move the patient in a sitting position.

[0004] 2. It occupies a large area and is not suitable for medical places with limited space.

[0005] 3. Lack of protective measures. Patients in the Department of Neurology often have poor mobility and need to pay special attention to safety protection. The invention does not have protective measures such as handrails, which not only makes it difficult for patients to get in and out of bed, requiring medical staff or family members to pay special attention to safety, but also easily leads to patients lacking a sense of security.

[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. Embodiment 1

[0025] refer to Figure 1-5 The present invention provides an examination bed for neurology, including a bed body 1, the bed body 1 includes a support seat 11, a cushion 12, a backrest 13 and a front support plate 14; the angle of the backrest 13 is adjustable, and the bottom of the backrest 13 is connected with an electric push rod in the prior art to facilitate switching of the patient between a lying position and a sitting position; armrests are also provided on both sides of the backrest 13.

[0026] Two leg airbags 26 are provided on the front support plate 14; the leg airbags 26 match the shape of human legs, and include a thigh airbag 261 and a calf airbag 262 that are interconnected. Specifically, the rear end of the thigh airbag 261 is installed on the front support plate 14, and a storage slot 141 for storing the leg airbag 26 is provided on the front support plate 14, so as to reduce the space occupied when the leg airbag 26 is not in use; a sitting posture conversion mechanism 2 is installed on the bed body 1, and the sitting posture conversion mechanism 2 is used to control the forward and backward movement of the seat cushion 12, and inflate the leg airbag 26, and at the same time push the leg airbag 26 out of the storage slot 141, so as to provide support for the patient's legs, and facilitate the patient sitting on the seat cushion 12 to move forward for examination.

[0027] The sitting posture conversion mechanism 2 includes a motor 21, a lead screw 22, a nut 23, an inner tube 24 and an outer tube 25; the motor 21 is installed at the bottom of the support seat 11, the lead screw 22 is connected to the output end of the motor 21, the nut 23 matches the lead screw 22, and the nut 23 is installed at the bottom of the seat cushion 12; matchingly, a first slide groove 111 is provided on the support seat 11, and the first slide groove 111 is used to provide a sliding channel for the lead screw 22; an inner tube 24 is installed at the bottom of the seat cushion 12, and the outer tube 25 is connected to the rear end of the thigh airbag 261 and communicated with each other; the front end of the inner tube 24 is sleeved in the rear end of the outer tube 25, and is slidably and sealedly connected to the outer tube 25; two second slide grooves 112 are provided on the support seat 11, which are used to provide a channel for the inner tube 24 to move forward and backward with the seat cushion 12; a limiting ring 241 is sleeved on the outer side of the front end of the inner tube 24, and the limiting ring 241 is used to limit the inner tube 24.

[0028] The working principle of the neurology examination bed in this embodiment is as follows: when it is necessary to change a patient in a supine position to a sitting position and then lift up the lower leg for further physical examination, the motor 21 is started, the motor 21 drives the lead screw 22 to rotate, and the rotation of the lead screw 22 drives the nut 23 to move forward, thereby moving the patient sitting on the cushion 12 forward; when the cushion 12 moves forward, it drives the inner tube 24 to move forward, thereby increasing the air pressure in the outer tube 25 and inflating the leg airbag 26. When the limiting ring 241 contacts the outer tube 25, it pushes the outer tube 25 forward and pushes the leg airbag 26 in the storage groove 141 forward to support the patient's legs. This can reduce the space occupied when the leg airbag 26 is not in use, and can support the patient's legs when needed, and the length of the support seat 11 is extended, so that the present invention is suitable for patients with larger bodies.

[0029] Neurological physical examination requires a large number of instruments. In order to store the examination instruments, a storage basket 7 and a storage ring 8 are also provided on the bed body 1 of the present invention; the storage basket 7 is connected under the bottom plate of the support seat 11 and is used to store general examination instruments; the storage ring 8 is used to place a percussion hammer. Embodiment 2

[0030] On the basis of the first embodiment, in order to be able to raise the patient's calf and facilitate the examination of the patient's leg, the second embodiment provides a preferred solution of the present invention.

[0031] refer to Figure 1-12A connecting rod 37 and a leg lifting mechanism 3 for lifting the patient's calf are provided between the thigh airbag 261 and the calf airbag 262. The leg-lifting mechanism 3 includes a foot pedal 31, a first spring 32, a rope 33 and a rotating block 34; the first spring 32 and the rope 33 are arranged in the front support plate 14, and specifically, the front support plate 14 is provided with a channel for the extension and contraction of the first spring 32 and the movement of the rope 33; the foot pedal 31 is installed on the side of the front support plate 14 to connect the first spring 32 and the rope 33; the rope 33 is connected to the rotating block 34 after passing through the connecting rod 37, and the rotating block 34 is connected to the calf airbag 262, specifically, a first connecting plate 35 is provided at the bottom of the thigh airbag 261, and a second connecting plate 36 is provided on the inner side of the calf airbag 262, a connecting rod 37 is installed at the lower end of the first connecting plate 35, and two blocks are provided on the connecting rod 37, and the blocks are used to limit the rope 33 along the axial direction of the connecting rod 37; the connecting rod 37 is connected to the rotating block 34, and the rotating block 34 is connected to the second connecting plate 36. When the doctor steps on the foot pedal 31 downward, the first spring 32 is compressed, and the end of the rope 33 connected to the foot pedal 31 moves downward, driving the rope 33 to be tensioned, so that the other end of the rope 33 drives the rotating block 34 to rotate around the connecting rod 37, driving the second connecting plate 36 to rotate, thereby lifting the calf airbag 262 upward, making it easier for the doctor to perform checks such as the jumping reflex.

[0032] In order to lock the leg-lifting mechanism 3 after the patient's calf is lifted to a certain angle, so that the calf airbag 262 is fixed, the present invention is also provided with a locking mechanism 4, which includes a sleeve 41, a pressing plate 42, a second spring 43 and a locking rod 44; the sleeve 41 is installed on the support seat 11 and is located above the foot pedal 31, which is convenient for the doctor to operate; the sleeve 41 is sleeved with a pressing plate 42, a second spring 43 and a locking rod 44, and specifically, the sleeve 41 is provided with an internal channel matching the pressing plate 42, the second spring 43 and the locking rod 44, and the lower end of the pressing plate 42 is connected to the locking rod 44. The locking rod 44 is connected to the front support plate 14, and the locking rod 44 is provided with a second spring 43 on its outer sleeve. The bottom of the second spring 43 is installed in the sleeve 41, and the lower end of the locking rod 44 passes through the second spring 43 and the sleeve 41, and is connected to the rope 33 in the front support plate 14; specifically, the lower end of the locking rod 44 is provided with a through hole 441 for the rope 33 to pass through, and the front support plate 14 is provided with a through groove 142, which is connected to the internal channel of the sleeve 41, and the locking rod 44 can slide along the internal channel of the sleeve 41 and the through groove 142. The inner diameter of the through groove 142 is smaller than the thickness of the lower end of the locking rod 44 and the sum of the diameters of the two ropes 33. When the pressing plate 42 is pressed downward, the locking rod 44 moves downward until it contacts the bottom of the through slot 142, the second spring 43 is compressed, and the ropes 33 on both sides of the locking rod 44 are in a straight line; when the pressing plate 42 is released, the elastic force of the second spring 43 resets the pressing plate 42, the locking rod 44 moves upward, and the ropes 33 on both sides of the locking rod 44 are bent. Since the inner diameter of the through slot 142 is smaller than the thickness of the lower end of the locking rod 44 and the sum of the diameters of the two ropes 33, the ropes 33 are stuck in the through slot 142, so that the ropes 33 stop moving and the leg lifting mechanism 3 is locked in place. In order to prevent the doctor from being unstable when stepping on the foot pedal 31 and pressing the pressing plate 42 with his hand, a handrail is connected to the rear end of the sleeve 41.

[0033] The working principle of the neurology examination bed in this embodiment is as follows: the pressing plate 42 is pressed, the locking rod 44 moves downward until it contacts the bottom of the through slot 142, the second spring 43 is compressed, the ropes 33 on both sides of the locking rod 44 are in a straight line, the rope 33 is able to slide in the front support plate 14, and the leg lifting mechanism 3 is unlocked. The doctor steps on the foot pedal 31, the first spring 32 is compressed, the end of the rope 33 connected to the foot pedal 31 moves downward, driving the rope 33 to be tensioned, so that the other end of the rope 33 drives the rotating block 34 to rotate around the connecting rod 37, driving the second connecting plate 36 to rotate, so that the calf airbag 262 is lifted upward, which is convenient for the doctor to perform knee jerk reflex and other examinations. After the leg-lifting mechanism 3 lifts the patient's calf to an appropriate angle, the pressing plate 42 is released, the elastic force of the second spring 43 resets the pressing plate 42, the locking rod 44 moves upward, and the ropes 33 on both sides of the locking rod 44 are bent. Because the inner diameter of the through groove 142 is smaller than the sum of the thickness of the lower end of the locking rod 44 and the diameter of the two ropes 33, the ropes 33 are stuck in the through groove 142, thereby stopping the ropes 33 from moving and locking the leg-lifting mechanism 3 in an appropriate position. Embodiment 3

[0034] On the basis of the first embodiment, in order to support the patient's shoulders and prevent the patient from feeling weightless during the downward rotation of the backrest 13, and to lengthen the armrests on both sides of the backrest 13 when the patient is in a supine position, the third embodiment provides a preferred solution of the present invention.

[0035] refer to Fig.13 The backrest 13 is provided with a shoulder support mechanism 5, which includes a back airbag 51 and a shoulder airbag 52; the back airbag 51 and the shoulder airbag 52 are connected to each other, and the back airbag 51 and the shoulder airbag 52 are in a semi-inflated state. When the patient approaches the backrest 13 and adjusts the angle of the backrest 13, and changes from a sitting position to a supine position, the back airbag 51 is squeezed, and the gas in the back airbag 51 flows into the shoulder airbag 52, inflating the shoulder airbag 52, and the shoulder airbag 52 is inflated, supporting the patient's shoulders, and avoiding the patient from feeling weightless when lying down.

[0036] Two adjustable armrests 6 are provided on the side of the backrest 13, and the adjustable armrest 6 includes an armrest outer tube 61, an armrest inner rod 62, a first connecting block 63, a second connecting block 64 and a third spring 65; one end of the armrest inner rod 62 is sleeved in the armrest outer tube 61 and is slidably connected with the armrest outer tube 61, and the armrest inner rod 62 is located at the rear side of the armrest outer tube 61. When in the sitting position, the armrest inner rod 62 is located at the upper end of the armrest outer tube 61; the armrest outer tube 61 is connected to the first connecting block 63, and the armrest inner rod 62 is connected to the second connecting block 64. The second connecting block 64 is located at the rear end of the first connecting block 63. When in the sitting position, the second connecting block 64 is located at the upper end of the first connecting block 63. The first connecting block 63 and the second connecting block 64 are slidably connected by the third spring 65, and the second connecting block 64 is filled with a fluid, and the fluid is preferably water.

[0037] When the backrest 13 is in an upright state, the fluid in the second connecting block 64 squeezes the third spring 65 under the action of gravity, so that the third spring 65 is in a compressed state, thereby reducing the total length of the adjustable armrest 6; when the patient adjusts the angle of the backrest 13 and converts it to a supine position, the pressure of the fluid in the second connecting block 64 on the third spring 65 gradually decreases, and the distance between the first connecting block 63 and the second connecting block 64 gradually increases, thereby reducing the length of the armrest inner rod 62 sleeved in the armrest outer tube 61, thereby increasing the total length of the adjustable armrest 6. Application Examples

[0038] Neurological physical examination usually includes general examination, cranial nerve examination, motor system, sensory system, reflex examination and autonomic nerve function examination, etc., involving the patient's switching between supine and sitting positions. Now, taking the example of using the present invention to perform a general examination in a supine position, then switching to a sitting position to perform a knee jerk reflex examination, and then raising the calf to a certain height to perform an ankle reflex, the operation method of the neurological examination bed of the present invention is specifically described.

[0039] Step 1: The patient sits on the cushion 12, starts the electric push rod, and slowly lays the backrest 13 flat. The patient squeezes the back airbag 51, so that the gas in the back airbag 51 flows into the shoulder airbag 52 to support the patient's shoulders. At the same time, as the backrest 13 rotates, the pressure of the fluid in the second connecting block 64 on the third spring 65 decreases, so that under the action of the elastic force, the distance between the first connecting block 63 and the second connecting block 64 gradually increases, and the adjustable armrest 6 is lengthened to strengthen the protection of the patient.

[0040] Step 2: Perform a physical examination on the patient in the supine position. After the examination, start the electric push rod again to raise the backrest 13, so that the patient can be turned to a sitting position, and the length of the adjustable armrest 6 can be shortened.

[0041] Step 3: Start the motor 21 to drive the lead screw 22 to rotate, thereby driving the nut 23 to move forward. The nut 23 drives the patient sitting on the cushion 12 to move forward. At the same time, the cushion 12 drives the inner tube 24 to slide forward in the outer tube 25 to inflate the leg airbag 26. When the limit ring 241 contacts the outer tube 25, the inner tube 24 drives the outer tube 25 to move forward, thereby pushing the leg airbag 26 out of the storage groove 141. The leg airbag 26 supports the patient's legs to improve the patient's comfort when sitting.

[0042] Step 4: Perform a physical examination with the patient in a sitting or standing position.

[0043] Step 5: The doctor holds the handrails on both sides of the support seat 11 with one hand and presses the pressing plate 42 with the other hand to compress the second spring 43, so that the locking rod 44 contacts the bottom of the through slot 142. At this time, the ropes 33 on both sides of the locking rod 44 are located in a straight line, unlocking the leg-lifting mechanism 3. Then the doctor steps on the foot pedal 31, stretches the first spring 32 downward, and causes the rope 33 to drive the rotating block 34 to rotate. When the rotating block 34 rotates to a proper position, the pressing plate 42 is released, and the second spring 43 drives the locking rod 44 to move upward. The ropes 33 on both sides of the locking rod 44 are no longer in the same straight line and are clamped by the through slot 142, and the calf airbag 262 is adjusted to a proper angle.

[0044] Step 6: Test the patient's ankle reflexes.
