Description

Technical Field

[0001] This invention relates to the field of biomedical engineering technology, and in particular to a photoelectronic digital pet X-ray imaging device. Background Technology

[0002] During pet X-ray imaging, the pet usually needs to be restrained to avoid blurring of the image due to the animal's movement.

[0003] However, existing restraint methods (such as straps, sandbags, and harnesses) can easily trigger stress responses in pets, leading to urinary and fecal incontinence and contamination of the photography bed. This not only affects the hygiene of subsequent shooting but also increases the workload of manual cleaning. While some equipment uses pads on the bed, existing pads are prone to urine leakage from the edges, contaminating the bed. Furthermore, the pads become damp after absorbing urine, causing direct contact between the pet's body and the urine, further exacerbating stress. This makes the equipment less convenient to use and also increases the need for consumables. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a photoelectronic digital pet X-ray imaging device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A photoelectric digital pet X-ray imaging device includes: a bed, and an X-ray machine mounted on the bed, and also includes a fixing component mounted on the bed for fixing the pet during imaging, the fixing component including a fixing ring mounted on the bed for fixing the pet's body, and a foot fixing bracket mounted on the fixing ring for fixing the pet's feet.

[0007] The bed is equipped with a collection component for collecting pet excrement during pet photography. The collection component includes two collection slots on the bed, and a sealing plate is slidably disposed at the opening of the collection slot for sealing the collection slot. When the fixing ring is used to fix the pet, the sealing plate is opened, and when the fixing ring is open, the sealing plate flushes the inside of the collection slot.

[0008] Preferably, the collection assembly further includes two connecting pipes disposed between the two sealing plates. The sealing plates are hollow inside, and multiple nozzles are provided at the bottom of the sealing plates. When the sealing plates move to close the opening of the collection tank, the nozzles spray out cleaning fluid.

[0009] Preferably, one of the fixing rings is fixedly disposed on the bed frame, and the other fixing ring is slidably disposed on the bed frame.

[0010] Preferably, the collection tank is also equipped with a processing component for the unified collection of excrement.

[0011] Preferably, the processing component includes a frustum-shaped collection hopper disposed within a collection trough, wherein one collection hopper is fixedly disposed, and the other collection hopper is slidably disposed within the collection trough. A connecting frame is fixedly disposed on the sliding collection hopper, and the other end of the connecting frame is fixedly disposed on a sliding fixing ring. A corrugated plate is disposed between the collection hopper and the top surface of the inner wall of the collection trough, and a shielding plate for sealing the end of the collection trough is fixedly disposed on one side of the corrugated plate on the movable collection hopper. The shielding plate is slidably disposed within the bed body.

[0012] Preferably, the two collection hoppers are arranged one above the other, and the two collection hoppers are interconnected, with a collection box movably connected to one of the collection hoppers.

[0013] Preferably, the bed is provided with a drive assembly for driving the sealing plate to open and supplying liquid to the inside of the sealing plate.

[0014] Preferably, the drive assembly includes a straight drive shaft rotatably disposed on one side of the bed, a fixing ring disposed on the drive shaft, a cam disposed at the end of the drive shaft, two airbags disposed inside the bed, the ends of the airbags being fixedly disposed on one of the sealing plates, a spring sleeved on the outside of the airbags, a drainage section disposed on the bed and communicating with the sealing plate, and a liquid storage tank communicating with the drainage section disposed at the bottom of the bed.

[0015] Preferably, the liquid storage tank includes a fixed cylinder fixedly mounted on the bed, a piston rod slidably mounted inside the fixed cylinder, a piston plate fixedly mounted at the end of the piston rod, the connection between the fixed cylinder and the air bladder being located on the rear side of the piston plate, the connection between the fixed cylinder and the liquid storage tank being located on the front side of the piston plate, and a flexible hose communicating with a sealing plate being provided on the front side of the piston plate. Solenoid valves are provided at the connection points between the liquid storage tank and the sealing plate and the fixed cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By manually rotating the footrest, the cam drives the piston rod, simultaneously triggering the airbag. This causes the sealing plate to automatically open the collection trough when the pet is secured and automatically close and flush when released, achieving simultaneous waste collection and trough cleaning. No electricity is required, avoiding motor noise that could frighten the pet and reducing manual cleaning steps. The two interconnected collection troughs, one above the other, along with a sliding fixing ring, adjust their position to accommodate pets of different sizes and genders, ensuring precise waste collection and preventing surface contamination. After each pet photoshoot, the nozzle automatically sprays cleaning fluid to flush the collection trough when the pet is secured and the sealing plate closes. The waste fluid is collected in a collection box, ensuring immediate waste removal, reducing odor spread, and maintaining a clean bed environment for subsequent pet photoshoots. The shielding plate slides with the collection trough, adaptively covering the opening to accommodate different pet sizes, ensuring waste collection while maintaining the flatness of the bed surface and pet comfort.

[0031] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0032] Combination Figures 1-7 This invention provides a photoelectronic digital pet X-ray imaging device, including: a bed 1, and an X-ray machine 2 mounted on the bed 1, and a fixing component 3 mounted on the bed 1 for fixing the pet during imaging. The fixing component 3 includes a fixing ring 31 mounted on the bed 1 for fixing the pet's body, and a foot fixing bracket 32 ​​mounted on the fixing ring 31 for fixing the pet's feet.

[0033] The bed frame 1 is equipped with a collection component 4 for collecting pet excrement during pet photography. The collection component 4 includes two collection slots 41 formed on the bed frame 1, and a sealing plate 42 for sealing the collection slots 41 is slidably disposed at the opening of the collection slots 41; Reference Figure 2 and Figure 3 When the fixing ring 31 secures the pet, the sealing plate 42 opens, and the sealing plate 42 rinses the inside of the collection tank 41. The pet to be photographed is placed on the bed 1, with its rear end facing one of the sealing plates 42 and its belly facing the other. Then, the two fixing rings 31 are rotated to fasten around the pet's body, and the two foot fixing brackets 32 on the fixing rings 31 are used to secure the pet's feet, preventing the pet's paws from moving around during the photographing process and causing blurry images. As the fixing ring 31 rotates, the sealing plate 42 slides, exposing the two collection slots 41. When the collection slots 41 are exposed, they can collect the excrement produced during pet photography. There is a distance between the two collection slots 41, so one collection slot 41 can collect the pet's feces. At the same time, there are male and female pets, and their excretory organs are located in different positions. The two collection slots 41 can complete the collection of the pet's urine and feces, and adapt to the differences between male and female pets, avoiding foreign objects being excreted during photography and causing contamination of the surface of the bed 1, thereby reducing the number of manual cleaning steps.

[0034] Preferred, Reference Figure 1 One of the fixing rings 31 is fixedly mounted on the bed frame 1, and the other fixing ring 31 is slidably mounted on the bed frame 1. The sliding fixing ring 31 can be adjusted according to the size of the pet.

[0035] Preferred, Reference Figure 5 and Figure 7The collection assembly 4 also includes two connecting pipes 43 that pass through the two sealing plates 42; the sealing plates 42 are hollow inside, and multiple nozzles 44 are provided at the bottom of the sealing plates 42; when the sealing plates 42 move to close the opening of the collection tank 41, the nozzles 44 spray cleaning fluid; when the pet is fixed, the sealing plates 42 are gradually pushed open, exposing the collection tank 41, thereby collecting the pet's excrement; when the pet is released, the sealing plates 42 close the collection tank 41 to prevent the spread of odor, and at the same time, during the closing process, the sealing plates 42 spray cleaning fluid to rinse the collection tank 41, so as to prevent the excrement in the collection tank 41 from being too pungent and affecting the environment.

[0036] Preferred, Reference Figure 7 The collection tank 41 is also equipped with a processing component 5 for unified collection of excrement. The processing component 5 can collect and process the excrement in a unified manner, so as to avoid the excrement being stored in the collection tank 41 and causing foreign matter to pollute the environment during the next use, and at the same time, to prevent the bed 1 from being contaminated.

[0037] Preferred, Reference Figure 5 , Figure 6 and Figure 7 The processing component 5 includes a frustum-shaped collection hopper 51 disposed within the collection trough 41, with one collection hopper 51 fixedly disposed and the other collection hopper 51 slidably disposed within the collection trough 41; a connecting frame 53 is fixedly disposed on the sliding collection hopper 51, and the other end of the connecting frame 53 is fixedly disposed on the sliding fixing ring 31; a corrugated plate 52 is disposed between the collection hopper 51 and the top surface of the inner wall of the collection trough 41, and a shielding plate 7 for sealing the end of the collection trough 41 is fixedly disposed on one side of the corrugated plate 52 on the movable collection hopper 51, and the shielding plate 7 is slidably disposed within the bed body 1; when excrement enters the collection trough 41 from the opening of the collection trough 41, the excrement will enter the collection hopper 51 and be collected by the collection hopper 51; one of the collection hoppers 51 is fixedly disposed... The collection bucket 51 is fixed on the movable ring 31. This means that when the ring 31 changes position according to the pet's size, the position of the collection bucket 51 changes accordingly. At this time, the collection bucket 51 can still adapt to pets of different sizes and still ensure the collection of pet excrement. When the collection bucket 51 moves, it means that the pet's size has become smaller. In order to improve the comfort of the bed 1, the adjustment of the collection bucket 51 will drive the cover plate 7 to move. At this time, the cover plate 7 can appropriately cover the opening of the collection trough 41, thereby reducing the opening size of the collection trough 41 and preventing the opening from being too large and causing the pet to lie down uncomfortably. Each time the collection bucket 51 moves, the corrugated plate 52 set on the collection bucket 51 can be adjusted appropriately to ensure that the collection bucket 51 always collects excrement and prevents excrement from leaking out.

[0038] Preferred, Reference Figure 5The two collection hoppers 51 are arranged one above the other and are interconnected. A collection box 54 is movably connected to one of the collection hoppers 51 to facilitate the unified collection and treatment of excrement. The collection box 54 is detachable and washable to reduce environmental pollution.

[0039] Preferred, Reference Figure 7 The bed body 1 is equipped with a drive assembly 6 for driving the sealing plate 42 to open and supplying liquid inside the sealing plate 42, which facilitates the control of the movement of the sealing plate 42 and also facilitates the cleaning of the inside of the collection tank 41.

[0040] Preferred, Reference Figure 6 and Figure 7 The drive assembly 6 includes a straight drive shaft 61 rotatably mounted on one side of the bed 1, with a fixing ring 31 mounted on the drive shaft 61; a cam 62 is provided at the end of the drive shaft 61; two airbags 64 are provided inside the bed 1, and the ends of the airbags 64 are fixedly mounted on one of the sealing plates 42; a spring is sleeved on the outside of the airbags 64; a drainage section 63 is provided on the bed 1, and the drainage section 63 communicates with the sealing plate 42; a liquid storage tank 65 communicating with the drainage section 63 is provided at the bottom of the bed 1; when the pet is secured, the foot restraint bracket 32 ​​needs to rotate downwards, at which time the cam 62 on the foot restraint bracket 32... 2. Squeeze the liquid storage tank 65 to generate gas, which enters the air bladder 64. The air bladder 64 expands and pushes the sealing plate 42 to move. As the sealing plate 42 moves, the opening of the collection trough 41 is gradually exposed, facilitating the collection of subsequent excrement. When the pet is released, the foot restraint 32 needs to rotate upward. At this time, the liquid storage tank 65 extracts the gas from the air bladder 64, causing the sealing plate 42 to close the collection trough 41. During the movement of the sealing plate 42, the liquid storage tank 65 presses liquid into the sealing plate 42, which is then sprayed out by the nozzle 44, thereby rinsing the surface of the collection hopper 51 and preventing the collection hopper 51 from having a strong odor that could cause environmental pollution.

[0041] Preferred, Reference Figure 6 and Figure 7The liquid storage tank 65 includes a fixed cylinder fixedly mounted on the bed 1. A piston rod is slidably mounted inside the fixed cylinder, and a piston plate is fixedly mounted at the end of the piston rod. The connection between the fixed cylinder and the air bladder 64 is located on the rear side of the piston plate, and the connection between the fixed cylinder and the liquid storage tank 65 is located on the front side of the piston plate. A flexible hose communicating with the sealing plate 42 is also provided on the front side of the piston plate. Solenoid valves are provided at the connection points between the liquid storage tank 65, the sealing plate 42, and the fixed cylinder. When the pet is fixed, i.e., the foot holder 32 drives the drive shaft 61 to drive the cam 62 to rotate counterclockwise, at which time the cam 62 squeezes the piston rod, causing the piston rod to force the air on the rear side of the piston plate into the air bladder 64. The air bladder 64 expands, thereby pushing the sealing plate 42 to move, so that the collection tank 41 is in the open state. When the piston plate forces air into the airbag 64, the other side of the piston plate is in an air-inhaling state. At this time, the piston plate draws the cleaning fluid from the storage tank 65 into the fixed cylinder. When the pet opens, the foot holder 32 rotates clockwise to drive the cam 62. At this time, the spring on the piston rod drives the piston rod to return to its original position. During the piston rod's return process, the gas in the airbag 64 is extracted, causing the sealing plate 42 to gradually seal the collection tank 41. Simultaneously, the connection between the fixed cylinder and the storage tank 65 closes. The piston plate forces the liquid in the fixed cylinder into the sealing plate 42, which is then sprayed out by the nozzle 44, thus forming a moving spray cleaning. The cleaning fluid and excrement are collected in the collection tank 54. The entire device is manually operated, avoiding the use of pumps and other electrical components, thus preventing the pet from being frightened.

[0042] Working principle

[0043] Adjust the position of one of the fixing rings 31 on the bed 1 according to the pet's size. Place the pet on the bed 1 so that its rump and abdomen correspond to the positions of the two collection slots 41, with the pet's body positioned between the two fixing rings 31. Manually rotate the foot restraint 32 downwards. The foot restraint 32 drives the straight drive shaft 61 to rotate counterclockwise. The cam 62 at the end of the drive shaft 61 rotates accordingly and squeezes the piston rod. The piston rod overcomes the spring resistance and pushes the piston plate to one side inside the fixed cylinder, forcing the air behind the piston plate into the airbag 64. The airbag 64 expands and pushes one of the sealing plates 42 outwards, opening the opening of the collection slot 41. At the same time, a negative pressure is generated on the other side of the piston plate, drawing the cleaning fluid from the reservoir 65 into the fixed cylinder. The two sealing plates 42 are linked by a connecting pipe 43 to achieve synchronous opening. Then, fasten the two fixing rings 31 around the pet's body and use the foot restraint 32 to secure the pet's limbs.

[0044] During the X-ray imaging process, the pet's excrement falls into the collection hopper 51 within the collection trough 41. Since the two collection hoppers 51 are positioned one above the other and interconnected, they can accommodate the different excretory organ positions of pets of different genders. When the sliding fixing ring 31 is adjusted, the connected collection hopper 51 and the shielding plate 7 move synchronously. The corrugated plate 52 extends and retracts to adapt to the positional changes, and the shielding plate 7 appropriately shields the opening of the collection trough 41, keeping the surface of the bed 1 flat and comfortable.

[0045] After filming, rotate the foot mount 32 upwards, causing the drive shaft 61 to rotate clockwise. The cam 62 disengages from the piston rod, and the spring pushes the piston rod back to its original position. During the piston rod's reset, the gas inside the airbag 64 is drawn back, and the sealing plate 42 slides towards the closing direction under negative pressure. Simultaneously, the solenoid valve between the fixed cylinder and the storage tank 65 closes, while the solenoid valve on the hose connected to the sealing plate 42 opens. The piston plate forces the cleaning fluid from the fixed cylinder into the sealing plate 42, which is then sprayed out through the nozzle 44 at the bottom of the sealing plate 42 to rinse the collection hopper 51. The rinsed waste liquid and excrement enter the collection tank 54 for unified treatment. After the sealing plate 42 is completely closed, the nozzle 44 stops spraying liquid.

[0046] Beneficial effects

[0047] By manually rotating the footrest bracket 32, the cam 62 is driven to compress the piston rod, simultaneously triggering the airbag 64. This causes the sealing plate 42 to automatically open the collection trough 41 when the pet is secured and automatically close and flush when released, achieving simultaneous collection of excrement and cleaning of the trough. This eliminates the need for electricity, avoiding motor noise that could frighten the pet and reducing manual cleaning steps. The two collection hoppers 51, one above the other, are designed to be interconnected, and the sliding fixing ring 31 allows for adjustment of the hopper 51's position, accommodating different sizes and genders of pets to ensure precise collection of excrement and prevent contamination. To prevent surface contamination of the bed 1, each time the equipment finishes shooting and the pet is secured, the nozzle 44 automatically sprays cleaning fluid to rinse the collection hopper 51 when the sealing plate 42 closes. This, combined with the collection box 54, collects the waste fluid, achieving the effect of immediate cleaning of excrement, reducing odor diffusion, and keeping the bed 1 clean. This provides a hygienic environment for subsequent pet shooting. In addition, the shielding plate 7 slides with the collection hopper 51 to adaptively shield the opening of the collection hopper 41, achieving the effect of adjusting the opening size according to different pet sizes. This ensures both the excrement collection function and maintains the flatness of the bed 1 surface and the pet's lying comfort.

[0048] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
