[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] See also Figures 1 to 10 The present invention provides a technical solution: a medical multifunctional nursing cart, comprising: a frame 1,

[0034] The vehicle frame 1 further comprises a turntable mechanism 2, which is arranged inside the vehicle frame 1 and adjusts its position according to the number of ampoules taken.

[0035] The cutting mechanism 3 is arranged inside the frame 1. The cutting mechanism 3 adjusts the cutting height and the rotation speed according to the type of ampoule bottle taken.

[0036] The turntable mechanism 2 includes a first drawer 201 slidably connected to the inside of the frame 1, a support plate 202 is fixedly connected to the inside of the first drawer 201, a first connecting rod 203 is rotatably connected to the inside of the support plate 202, a rotating member 204 is fixedly connected to the top of the first connecting rod 203, a friction limiter 205 is fixedly connected to one end of the rotating member 204, a second connecting rod 206 is fixedly connected to the inside of the friction limiter 205, a spring 207 is fixedly connected to the surface of the second connecting rod 206, one end of the spring 207 is fixedly connected to a limiting box 208, one end of the second connecting rod 206 is fixedly connected to a placement box 209, a placement slot is provided in the placement box 209, and the placement slot is fixedly connected to the inside of the placement slot. There is a fixed spring 210, one end of the fixed spring 210 is fixedly connected to a lifting platform 211, one end of the lifting platform 211 is fixedly connected to a moving block 212, the inside of the placement groove is fixedly connected to an airbag ring 213, one end of the airbag ring 213 is fixedly connected to a first air outlet pipe 214, the bottom of the first connecting rod 203 is fixedly connected to a rotary joint 215, one side of the rotary joint 215 is fixedly connected to a second air outlet pipe 216, one end of the second air outlet pipe 216 is fixedly connected to a fixed pipe 217, the inside of the fixed pipe 217 is fixedly connected to a first spring 218, one end of the first spring 218 is fixedly connected to a moving ball 219, and one side of the fixed pipe 217 is fixedly connected to a photoelectric sensor 220.

[0037] The first drawer 201 is connected to the inside of the vehicle frame 1 by a guide rail, providing an installation foundation and activity space for other components of the turntable mechanism 2, making it convenient for medical personnel to pull it out for operation. The support plate 202 is fixed inside the first drawer 201 to support components such as the first connecting rod 203, ensuring the stability of the entire turntable mechanism 2. The first connecting rod 203 passes through the support plate 202 and is rotatably connected thereto, serving as the central axis of the turntable mechanism 2. The rotating member 204 is fixed to the top of the first connecting rod 203. The first drawer 201 moves through the rotating member 204 to accumulate elastic potential energy for the spring 207, and the second connecting rod 206 drives the placement box 209 to partially reset, and works together with the friction limiter 205 to achieve accurate positioning of the placement box 209. The friction limiter can accurately position the placement box 209 and prevent the spring 207 from overloading. When the spring 207 accumulates enough energy, the friction limiter slips to protect the turntable mechanism 2. When rotation is required, the placement box 209 is placed. When the placement box 209 loses the restriction of the clamping plate 221, the mainspring 207 resets and drives itself to rotate, thereby driving the entire turntable mechanism 2 to rotate, making it convenient to adjust the position of the placement box 209 to take out different numbers of ampoules. The second connecting rod 206, the mainspring 207 and the limit box 208 inside the friction limiter 205 form an energy storage and limiting structure. The mainspring 207 is stretched when the placement box 209 rotates, storing elastic potential energy. When the placement box 209 reaches the target position, the mainspring 207 releases energy, and the airbag ring 213 surrounds the placement groove. When the ampoule is taken out, the internal gas of the fixed tube 217 returns to the airbag ring 213 through the first air outlet pipe 214, the rotary joint 215, and the second air outlet pipe 216. The first spring 218 resets and drives the moving ball 219 to move. When the moving ball 219 moves, it triggers the photoelectric sensor 220 for detecting the placement status and quantity of the ampoules, and converts the detection data into an electrical signal and transmits it to the control device 6.

[0038] A limiting groove is provided on the surface of the placement box 209, and a card plate 221 is clamped inside the limiting groove. One end of the card plate 221 is rotatably connected to a support rod 222, and the support rod 222 is rotatably connected to the inside of the first drawer 201. One side of the card plate 221 is fixedly connected to a second spring 223, and the second spring 223 is fixedly connected to the inside of the first drawer 201.

[0039] The limiting groove on the surface of the placement box 209 cooperates with the card plate 221. The card plate 221 is engaged with the limiting groove through the action of the second spring 223 and the support rod 222. After the placement box 209 is rotated to the appropriate position, the card plate 221 is locked into the limiting groove, further fixing the placement box 209 to prevent it from accidentally rotating and ensuring the stability during the ampoule bottle removal process. After the ampoule bottle is taken out from the placement groove, the fixed spring 210, the lifting platform 211 and the moving block 212 inside the placement box 209 lose pressure and reset to push the lifting platform 211 to move. The movement of the lifting platform 211 drives the moving block 212 to move. The moving block 212 squeezes the card plate 221 and pushes it out, so that the placement box 209 loses the restriction of the card plate 221 and is driven to rotate by the reset of the clockwork 207.

[0040] The rotating member 204 includes an inner gear ring 2041 fixedly connected to the top of the first connecting rod 203, a third spring 2042 fixedly connected to one side of the inner gear ring 2041, a limiting ball 2043 fixedly connected to one end of the third spring 2042, an outer gear ring 2044 rotatably connected to the surface of the inner gear ring 2041, a fixed gear plate 2045 meshing between the teeth of the outer gear ring 2044, the fixed gear plate 2045 fixedly connected to the inside of the frame 1, and a first empty groove adapted to the fixed gear plate 2045 is opened on the surface of the first drawer 201.

[0041] The outer gear ring 2044 moves when it is engaged with the fixed gear plate 2045. The outer gear ring 2044 drives the inner gear ring 2041 to rotate through the third spring 2042 and the limiting ball 2043, thereby positioning the rotating part 204 and accumulating elastic potential energy for the mainspring 207. The first drawer 201 fixes the position of the fixed gear plate 2045 to ensure that the position of the fixed gear plate 2045 will not change. The first empty groove facilitates the engagement of the fixed gear plate 2045 and the outer gear ring 2044.

[0042] The cutting mechanism 3 includes a second drawer 301 slidably connected to the inside of the frame 1, a placement rack 302 is fixedly connected to the inside of the second drawer 301, a limiting plate 303 is fixedly connected to the top of the placement rack 302, a resistance plate 304 is slidably connected to the top of the limiting plate 303, a limiting rod 305 is fixedly connected to one end of the resistance plate 304, a surface of the limiting rod 305 is rotatably connected to a rotating gear plate 306, an arc groove is provided on the surface of the rotating gear plate 306, the limiting rod 305 is slidably connected to the inside of the arc groove, and a movable gear plate 307 is engaged between the teeth of the rotating gear plate 306.

[0043] The second drawer 301 is slidably connected to the inside of the frame 1 and can be pulled out as needed to facilitate medical staff to perform ampoule cutting operations. The placement rack 302 is fixed inside the second drawer 301 and is used to place the ampoules to be cut. When the first electric push rod 308 pushes the movable tooth plate 307 to move, the movable tooth plate 307 engages the rotating tooth plate 306 to rotate, and the arc groove on the surface of the rotating tooth plate 306 cooperates with the limiting rod 305. The limiting rod 305 sleeved on the surface of the rotating tooth plate 306 moves, and the resistance plate 304 slides on the top of the limiting plate 303 under the synchronous action of the limiting rod 305, thereby adjusting the resistance force and position of the ampoule to meet the cutting requirements of different types of ampoules.

[0044] One end of the movable tooth plate 307 is fixedly connected to the first electric push rod 308, and the first electric push rod 308 is fixedly connected to the inside of the second drawer 301. The bottom of the movable tooth plate 307 is fixedly connected to the sliding rheostat 309, and the sliding rheostat 309 is fixedly connected to the inside of the second drawer 301.

[0045] Moving tooth plate 307 and sliding rheostat 309: When the moving tooth plate 307 engages with the rotating tooth plate 306 and rotates, the moving tooth plate 307 pushes the slider of the sliding rheostat 309 to move. The slider slides on the surface of the sliding rheostat 309 to change the resistance of the device, thereby reducing the resistance experienced by the device, thereby adjusting the rotation speed of the second motor 314 to adapt to the cutting requirements of different types of ampoules.

[0046] A first motor 310 is fixedly connected to one side inside the second drawer 301, and an output end of the first motor 310 is fixedly connected to a first connecting ring 311.

A second motor 314 is fixedly connected to the bottom of the arc plate 313. A second connecting ring 315 is fixedly connected to the output end of the second motor 314. A friction member 4 is fixedly connected to the bottom of the second connecting ring 315.

[0047] The control device 6 controls the first motor 310 through the received electrical signal. The first motor 310 drives the curved plate 313 to rotate through the first connecting ring 311 and the second electric push rod 312 so that it rotates to a suitable angle. The control device 6 controls the second electric push rod 312 to adjust the height of the curved plate 313, thereby adjusting the height of the cutting component to adapt to different types of ampoules. The second motor 314 is connected to the friction member 4 through the second connecting ring 315. The second motor 314 drives the friction member 4 to rotate to realize the cutting operation of the ampoule.

[0048] The friction member 4 includes a square plate 401 fixedly connected to the bottom of the second connecting ring 315. A telescopic rod 402 is fixedly connected inside the square plate 401. One end of the telescopic rod 402 is fixedly connected to a synchronization rod 403. A grinding wheel 404 is rotatably connected to the surface of the synchronization rod 403.

[0049] The square plate 401 in the friction member 4 serves as the installation base, and the telescopic rod 402 and the synchronization rod 403 ensure that the grinding wheel 404 can stably contact the ampoule during the cutting process and make a certain degree of adaptive adjustment according to the shape and size of the ampoule to ensure the cutting effect.

[0050] A protective frame 5 is fixedly connected to one side of the second drawer 301 , a control device 6 is fixedly connected inside the protective frame 5 , and a second empty slot adapted to the control device 6 is provided inside the second drawer 301 .

[0051] The protective frame 5 protects the control device 6 to prevent it from being hit or damaged during the use of the cart. The control device 6 receives the signal from the photoelectric sensor 220 and controls the actions of the first electric push rod 308, the second electric push rod 312, the first motor 310 and the second motor 314 according to a preset program to achieve automatic adjustment of the cutting height and the rotation speed.
