Description

Technical Field

[0001] This invention relates to the field of transfer vehicle technology, and specifically to a transfer vehicle. Background Technology

[0002] Medical transport carts are medical transport equipment specifically designed for departments, primarily used for the safe transport and temporary storage of related items. They typically employ a layered structure, equipped with sealed storage spaces, collision-resistant protection, and silent casters. This prevents endoscopes from being contaminated, worn, or damaged during transport, while allowing for flexible movement between examination rooms, sterilization rooms, and wards, improving instrument turnover efficiency. Furthermore, some models support customized partitions to accommodate different sizes of endoscopes and accessories, meeting the core clinical needs for clean storage and convenient access. They are crucial auxiliary equipment for ensuring instrument safety and optimizing workflows in endoscopic diagnostic and treatment processes.

[0003] Chinese patent CN112451105A discloses an improved endoscope transport cart for gastroenterology and its usage method, including a support platform and a push support frame. The push support frame is mounted on the support platform, and two vertical support plates are symmetrically connected to opposite side walls of the push support frame, with vertical sliding grooves provided on the vertical support plates. The height of the storage mechanism in this invention can be easily adjusted, eliminating the need for medical personnel to bend over when retrieving instruments, thus saving time and effort. Furthermore, the storage mechanism features a push-type lid that remains attached to the storage box during the pushing process, ensuring that the lid does not occupy medical space during actual operation. Therefore, this improved endoscope transport cart for gastroenterology is more suitable for use by medical personnel and better aligns with the principle of maximizing the use of medical space. However, this device still has the following problems:

[0004] After medical staff use a digestive endoscope to examine a patient, the patient's blood may remain on the endoscope. Medical staff will pre-treat the blood and mucus on the surface of the endoscope at the bedside. However, if the patient carries an infectious virus, it cannot be completely eliminated. The equipment still needs to be touched by medical staff during use, which may leave the virus on the surface of the transport vehicle. There is a risk of virus transmission when the transport vehicle is pushed to the sterilization supply department for sterilization.

[0005] Based on this, the present invention designs a transfer vehicle to solve the above problems. Summary of the Invention

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0036] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 A transfer vehicle, comprising a transfer vehicle body 1;

[0037] The main body 1 of the transport vehicle is equipped with a self-avoidance mechanism 2 for automatically avoiding obstacles when placing digestive endoscopes to facilitate the retrieval and placement by medical staff.

[0038] The main body 1 of the transfer vehicle is also equipped with a self-opening and closing mechanism 3 for automatically controlling the opening and closing of the end cover when the self-avoiding mechanism 2 automatically avoids obstacles;

[0039] The self-avoidance mechanism 2 includes a drive assembly, a transmission assembly 22, a rotation assembly 23, and a gastroscope placement assembly 24; the transport vehicle body 1, the transmission assembly 22, and the rotation assembly 23 are all connected to the drive assembly; the transport vehicle body 1 and the transmission assembly 22 are both connected to the rotation assembly 23, and the transport vehicle body 1 and the rotation assembly 23 are both connected to the gastroscope placement assembly 24; the drive assembly is used to drive the transmission assembly 22; the transmission assembly 22 is used for transmission between the drive assembly and the rotation assembly 23, and the rotation assembly 23 is used to drive the gastroscope placement assembly 24 to rotate synchronously in opposite directions; the gastroscope placement assembly 24 is used to place a digestive endoscope.

[0040] In this invention, when medical staff need to place a digestive endoscope that needs to be disinfected into the transport vehicle, they use their feet to start the drive assembly. The drive assembly drives the endoscope placement assembly 24 to rotate synchronously in the opposite direction through the transmission assembly 22 and the rotation assembly 23 to avoid obstruction, making it easier to place the digestive endoscope on the lower side. At the same time as the endoscope placement assembly 24 rotates synchronously in the opposite direction, the opening and closing mechanism 3 automatically controls the upper end of the endoscope placement assembly 24 to open. The entire process does not require medical staff to contact the vehicle body, reducing the possibility of viruses adhering to the surface of the transport vehicle.

[0041] Example 2: In some embodiments, such as Figures 1-4As shown, in a preferred embodiment of the present invention, the drive assembly adopts a first drive assembly 21, which includes a self-locking motor 211, a reducer 212, and a switch 213; both the self-locking motor 211 and the reducer 212 are fixedly connected to the main body 1 of the transfer vehicle; the drive end of the self-locking motor 211 is fixedly connected to the input end of the reducer 212; the reducer 212 is connected to the transmission assembly 22; the self-locking motor 211 is electrically connected to the switch 213 through a controller; the switch 213 is fixedly connected to the main body 1 of the transfer vehicle.

[0042] The transmission assembly 22 includes a first bevel gear 221, a second bevel gear 222, and a third bevel gear 223; the first bevel gear 221 is fixedly connected to the output end of the reducer 212; the second bevel gear 222 and the third bevel gear 223 are symmetrically distributed vertically; both the second bevel gear 222 and the third bevel gear 223 are meshed with the first bevel gear 221; both the second bevel gear 222 and the third bevel gear 223 are connected to the rotating assembly 23.

[0043] The rotating assembly 23 includes a first rotating shaft 231, a second rotating shaft 232, and a sleeve shaft 233; the first rotating shaft 231 and the second rotating shaft 232 are both rotatably connected to the sleeve shaft 233; the first rotating shaft 231 is fixedly connected to the second bevel gear 222; the second rotating shaft 232 is fixedly connected to the third bevel gear 223; and the sleeve shaft 233 is fixedly connected to the main body 1 of the transfer vehicle.

[0044] Two sets of endoscope placement components are symmetrically and staggered vertically on both sides.

[0045] The endoscope placement assembly 24 includes a connecting block 241 and a placement chamber 242; two connecting blocks 241 from different groups are fixedly connected to the side walls of the first rotating shaft 231 and the second rotating shaft 232, respectively; two limiting grooves 243 are provided on the side wall of the sleeve shaft 233; the connecting block 241 is slidably connected to the limiting grooves 243; one end of the connecting block 241 away from the first rotating shaft 231 and the second rotating shaft 232 is fixedly connected to the placement chamber 242.

[0046] In this invention, when medical staff need to place a digestive endoscope that needs to be disinfected into a transport vehicle, they use a foot kick switch 213. The switch 213 activates a self-locking motor 211 via a controller. The self-locking motor 211 drives the first bevel gear 221 to rotate via a reducer 212. The rotation of the first bevel gear 221 drives the second bevel gear 222 and the third bevel gear 223 to rotate synchronously in opposite directions. This causes the first rotating shaft 231 and the second rotating shaft 232 to rotate synchronously in opposite directions. The first rotating shaft 231 and the second rotating shaft 232 each drive the two placement chambers 242 to rotate synchronously in opposite directions via a connecting block 241. This allows the upper and lower placement chambers 242 to complete an avoidance action via a limiting slide groove 243, making it easier for medical staff to place the digestive endoscope.

[0047] like Figures 1-5As shown, each placement compartment 242 is equipped with a set of self-opening and closing mechanisms 3 at its upper end; the two sets of self-opening and closing mechanisms 3 are symmetrically distributed from left to right and staggered vertically; each self-opening and closing mechanism 3 includes an opening and closing component 31 and a self-opening and closing drive component 32; the opening and closing component 31 is connected to the placement compartment 242; the self-opening and closing drive component 32 is connected to the sleeve shaft 233; the opening and closing component 31 is used to seal the placement compartment 242; the self-opening and closing drive component 32 is used to control the opening and closing of the opening and closing component 31.

[0048] The opening and closing assembly 31 includes an end cap 311 and an end cap pivot 312; the end cap 311 and the end cap pivot 312 are fixedly connected; the end cap pivot 312 is rotatably connected to the placement compartment 242; a torsion spring is sleeved on the end cap pivot 312, one end of the torsion spring is fixedly connected to the end cap pivot 312, and the other end of the torsion spring is fixedly connected to the placement compartment 242, and the torsion spring is used to drive the end cap pivot 312 to rotate and drive the end cap 311 to open;

[0049] The self-opening and closing drive assembly 32 includes a connecting rod 321 and an abutting rod 322; the connecting rod 321 is fixedly connected to the side wall of the sleeve shaft 233; the connecting rod 321 and the abutting rod 322 are fixedly connected.

[0050] In this invention, before the self-locking motor 211 starts and drives the two placement chambers 242 to avoid each other, the abutment rod 322 abuts against the upper end of the end cover 311, so that the end cover 311 is tightly sealed against the placement chamber 242. When avoiding each other, the placement chamber 242 rotates around the sleeve shaft 233, causing the abutment rod 322 to roll on the end cover 311 until the abutment rod 322 leaves the upper end of the end cover 311. At this time, the end cover 311 is driven by the torsion spring to rotate around the end cover shaft 312, so that the end cover 311 opens, making it easier to place the digestive endoscope into the placement chamber 242. After the digestive endoscope is placed, the self-locking motor 211 drives the placement chamber 242 to reset, so that the abutment rod 322 abuts against the upper side of the end cover 311 again. The abutment rod 322 pushes the end cover 311 to rotate around the end cover shaft 312 to reset and seal the placement chamber 242.

[0051] Example 4: In some embodiments, such as Figures 6-7As shown, in a preferred embodiment of the present invention, the driving assembly adopts a second driving assembly 25; the second driving assembly 25 includes a driving gear 251, a rack 252, a sliding block 253, a first limiting slide rod 254, a return spring 255, a locking groove 256, a locking block 257, a second limiting rod 258, and a locking spring 259; the driving gear 251 is fixedly connected to the first bevel gear 221; the rack 252 is meshed with the driving gear 251; the sliding block 253 is fixedly connected to the rack 252; the lower end of the sliding block 253 is fixedly connected to a plurality of first limiting slide rods 254; a foot pedal is fixedly installed on the upper end of the sliding block 253; the first limiting slide rods 254 and... The sleeve shaft 233 is in a limiting sliding connection; a return spring 255 is sleeved on the outside of the first limiting slide rod 254; the lower end of the return spring 255 is fixedly connected to the sleeve shaft 233; the upper end of the return spring 255 is fixedly connected to the sliding block 253; a locking groove 256 is provided on the sliding block 253; a locking block 257 is engaged with the locking groove 256; one end of the locking block 257 away from the sliding block 253 is fixedly connected to a plurality of second limiting rods 258, and the second limiting rods 258 are in a limiting sliding connection with the sleeve shaft 233; a locking spring 259 is sleeved on the outside of the second limiting rod 258; one end of the locking spring 259 is fixedly connected to the locking block 257; the other end of the locking spring 259 is fixedly connected to the sleeve shaft 233.

[0052] In this invention, the operator steps on the foot pedal, causing the sliding block 253 to move downward under the limit of the first limiting slide bar 254. The movement of the sliding block 253 drives the drive gear 251 to rotate through the rack 252. The rotation of the sliding block 253 drives the first bevel gear 221 to rotate until the locking groove 256 is aligned with the locking block 257. The locking block 257 is pushed by the locking spring 259 and slides under the limit of the second limiting rod 258, so that the locking block 257 and the locking groove 256 are engaged to lock the position of the sliding block 253. When unlocking is required, simply kick the locking block 257 to reset it. The sliding block 253 is then reset under the push of the reset spring 255, so that the reset of the sliding block 253 drives the first bevel gear 221 to reset.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
