After the patient vomits, the garbage bag can automatically fall into the collection bucket, and there is no need to manually handle the garbage bag, which improves the efficiency of handling vomit and reduces the contact between recycling personnel and garbage bags, thereby reducing the possibility of pathogens spreading from vomit to recycling personnel. After the garbage bag is collected, the garbage bag is separated from the air on the top of the cylinder, which can effectively prevent the odor of vomit in the garbage bag from emanating to the top of the cylinder. This allows the staff to reduce the impact of odor on the staff when putting on new garbage bags, providing a safer and more hygienic environment for patients and staff.

[0012] The present invention has the following beneficial effects: When the patient of the present invention shows a sign of vomiting, the patient tilts to one side from the chemotherapy bed body, and the elbow will press on the top of the pressing plate, thereby applying a downward pressure to the pressing plate and the return spring 1. After the pressing plate moves downward, it drives the connecting rod 1 to move downward. The cylinder is restricted by the slide groove. After the connecting rod 1 moves downward, it drives the slide rod 1 to force the cylinder to rotate. After the cylinder rotates, it provides rotational power for the gear. The gear is meshed with the rack 2. After the gear rotates, it forces the rotating ring to rotate. After the rotating ring rotates, it drives the plurality of racks 1 to drive the plurality of tooth plates to rotate. The tooth plates rotate and expand to the surroundings, and no longer block the top of the movable groove. At this time, the patient can vomit into the cylinder through the movable groove. After the patient finishes vomiting, he lies flat on the chemotherapy bed body and no longer applies a downward pressure to the pressing plate and the return spring 1. The return spring 1 drives the pressing plate back to its original position. After the pressing plate is reset, it drives the plurality of tooth plates to be reset, so that the plurality of tooth plates are aligned again. The top of the movable groove is blocked, so that the patient's vomit can be blocked to prevent the odor in the vomit from drifting into the surrounding environment. When the patient shows signs of vomiting and presses his elbow on the pressure plate, a series of mechanical actions can be quickly triggered to open the movable groove in a very short time, allowing the patient to vomit in time, avoiding vomitus splashing everywhere due to not being able to find a suitable vomiting position in time, increasing the difficulty of cleaning and the patient's discomfort. When the patient feels nauseous, the patient can quickly find a vomiting outlet, reducing the patient's tension and anxiety and improving the patient's comfort during chemotherapy. After the patient finishes vomiting, the tooth plate can be quickly reset to block the top of the movable groove, effectively blocking the odor in the vomit from drifting into the surrounding environment, which is very important for keeping the air in the ward or treatment area fresh. It can not only make the patient feel more comfortable, but also reduce the adverse effects of the odor on other patients and medical staff.

[0013] Before the present invention is used, a garbage bag is first put on the outer wall of the annular plate. At this time, there is no vomit in the garbage bag. When the patient presses the pressing plate to vomit, the pressing plate drives the second slide bar to move downward. After the second slide bar moves downward, the annular block is pulled downward by the connecting rod. Restricted by the inclined surface of the inclined surface block and the inclined surface of the inclined surface groove, the inclined surface groove contacts the inclined surface block when the annular block moves downward, forcing the inclined surface block to drive the circular rod to slide into the cylinder body, applying an extrusion force to the telescopic spring, and the circular rod slides inward and drives the clamping block to move inward. After the clamping block moves inward, a clamping force is applied to the garbage bag on the outer wall of the annular plate to clamp the garbage bag. The garbage bag on the outer wall of the annular plate is clamped and fixed. After the garbage bag is fixed, it can be prevented from sliding down due to the increase in weight when vomitus enters the garbage bag. By fixing the garbage bag, it can effectively prevent the garbage bag from sliding down when the weight of the vomitus increases. This allows patients to avoid worrying about the garbage bag falling off and causing vomitus to spill during vomiting, and can ensure that the vomitus is accurately collected in the bag, preventing the vomitus from spilling around the device or on the ground, thereby maintaining the cleanliness of the treatment environment. Reducing the risk of vomitus splashing onto the inner wall of the cylinder can reduce the risk of cross infection and reduce the possibility of infection for patients and medical staff.

[0014] After the garbage bag is put on the outer wall of the annular plate of the present invention, the garbage bag is in a state of not being fully expanded. When the annular block moves downward, the push plate is driven to move downward in the suction pipe through the connecting rod, so that the air at the bottom of the garbage bag can be sucked into the suction pipe. When the push plate moves downward in the suction pipe, a negative pressure is formed at the part of the bottom of the garbage bag connected with the suction pipe, while the air pressure outside the garbage bag is relatively high. Under the effect of the air pressure difference, the external air will squeeze the garbage bag, so that the concave part inside the garbage bag is expanded, thereby realizing the fully expanded state of the garbage bag. The expanded garbage bag provides a larger accommodating space for vomitus, and can more accurately collect the vomitus of the patient. When the patient vomits, the vomitus can directly fall into the fully expanded garbage bag, avoiding the situation that the vomitus splashes out or cannot accurately fall into the bag due to the garbage bag not being expanded, thereby improving the accuracy and efficiency of vomitus collection.

[0015] After the patient vomits, the vomit is collected by the garbage bag and the patient no longer applies downward pressure to the pressure plate. At this time, the annular block moves upward to reset. After the annular block is reset, the inclined groove at the bottom of the annular block no longer contacts the inclined block, and the extrusion force exerted on the telescopic spring disappears, thereby forcing the circular rod to drive the clamping block to move outward. After the clamping block moves outward, it no longer exerts a clamping force on the garbage bag. At this time, the garbage bag is affected by the weight of the vomit and falls downward. The garbage bag falls downward on the top of the sealing plate. The sealing plate is affected by the weight of the garbage bag and rotates with the V-shaped plate as the midpoint. After the sealing plate rotates, an extrusion force is exerted on the arc spring. At this time, a gap is formed between the sealing plate and the cylinder body, and the garbage bag falls to the bottom of the cylinder through the gap. By opening the door on the outer wall of the cylinder, the collection bucket can be placed at the bottom of the cylinder. The inner wall of the cylinder is fixed with the garbage bag at the bottom, so that the fallen garbage bag can fall directly into the collection barrel. When the garbage bag falls into the collection barrel, the pressure on the top of the sealing plate disappears, and the arc spring drives the sealing plate back to its original position to seal the space between the cylinder body and the garbage bag. After the patient vomits, the garbage bag can automatically fall into the collection barrel, and there is no need to manually handle the garbage bag, which improves the efficiency of handling vomitus and reduces the contact between recycling personnel and garbage bags, thereby reducing the possibility of pathogens spreading from vomitus to recycling personnel. After the garbage bag is collected, the garbage bag is separated from the air on the top of the cylinder body, which can effectively prevent the odor of vomitus in the garbage bag from emanating to the top of the cylinder body. This allows the staff to reduce the impact of odor on the staff when putting on new garbage bags, providing a safer and more hygienic environment for patients and staff.

When the garbage bag falls into the collection bin, the pressure on the top of the sealing plate 302 disappears, and the arc spring 303 drives the sealing plate 302 back to its original position to seal the space between the cylinder 102 and the garbage bag. After the patient vomits, the garbage bag can automatically fall into the collection bin, and there is no need to manually handle the garbage bag, which improves the efficiency of handling vomit and reduces the contact between the recycling personnel and the garbage bag, thereby reducing the possibility of pathogens spreading from vomit to the recycling personnel. After the garbage bag is collected, the garbage bag is separated from the air at the top of the cylinder 102, which can effectively prevent the odor of vomit in the garbage bag from emanating to the top of the cylinder 102. This allows the staff to reduce the impact of the odor on the staff when putting on new garbage bags, providing a safer and more hygienic environment for patients and staff.

[0028] A specific application of this embodiment is: Before use, a garbage bag is first put on the outer wall of the annular plate 207. At this time, there is no vomit in the garbage bag. When the patient presses the pressing plate 203 to vomit, the pressing plate 203 drives the sliding bar 202 to move downward. After the sliding bar 202 moves downward, the annular block 214 is pulled downward by the connecting rod 205. Restricted by the inclined surfaces of the inclined block 212 and the inclined groove 215, the annular block 214 is in contact with the inclined block 212 when it moves downward, forcing the inclined block 212 to drive the circular rod 208 to slide into the cylinder 102, applying an extrusion force to the telescopic spring 211, and the circular rod 208 slides inward and drives the clamping block 209 to move inward. After the clamping block 209 moves inward, A clamping force is applied to the garbage bag on the outer wall of the annular plate 207 to clamp and fix the garbage bag on the outer wall of the annular plate 207. After the garbage bag is fixed, it can be prevented from sliding down due to the increase in weight when vomitus enters the garbage bag. By fixing the garbage bag, it can be effectively prevented from sliding down when the weight of the vomitus increases. This allows patients to avoid having to worry about the garbage bag falling off and causing vomitus to spill during vomiting, and can ensure that the vomitus is accurately collected in the bag to prevent vomitus from spilling around the device or on the ground, thereby keeping the treatment environment clean. Reducing the risk of vomitus splashing onto the inner wall of the cylinder 102 can reduce the risk of cross infection and reduce the possibility of infection for patients and medical staff.

[0029] After the garbage bag is put on the outer wall of the annular plate 207, the garbage bag is in a state of not being fully expanded. When the annular block 214 moves downward, the push plate 306 is driven to move downward in the suction pipe 305 through the connecting rod 307, so that the air at the bottom of the garbage bag can be sucked into the suction pipe 305. When the push plate 306 moves downward in the suction pipe 305, a negative pressure is formed at the part of the bottom of the garbage bag connected to the suction pipe 305, and the air pressure outside the garbage bag is relatively high. Under the action of the air pressure difference, the external air will squeeze the garbage bag, so that the concave part inside the garbage bag is expanded, thereby realizing the fully expanded state of the garbage bag. The expanded garbage bag provides a larger accommodation space for vomitus, and can more accurately collect the patient's vomitus. When the patient vomits, the vomitus can directly fall into the fully expanded garbage bag, avoiding the situation where vomitus splashes or cannot accurately fall into the bag due to the garbage bag not being expanded, thereby improving the accuracy and efficiency of vomitus collection.

[0030] When the patient shows signs of vomiting, the patient leans to one side from the chemotherapy bed 101, and the elbow presses on the top of the pressing plate 203, thereby applying a downward pressure to the pressing plate 203 and the return spring 1 204. The pressing plate 203 moves downward and drives the connecting rod 114 to move downward. The cylinder 111 is restricted by the slide groove 112. The connecting rod 114 moves downward and drives the slide rod 113 to force the cylinder 111 to rotate. The rotation of the cylinder 111 provides rotation power for the gear 110, and the gear 110 and the rack 104 are connected. 9 meshes, and the gear 110 rotates to force the rotating ring 105 to rotate. After the rotating ring 105 rotates, it drives a plurality of racks 108 to drive a plurality of tooth plates 107 to rotate. The tooth plates 107 rotate and expand to the surroundings, and no longer block the top of the movable groove 104. At this time, the patient can vomit into the cylinder 102 through the movable groove 104. After the patient finishes vomiting, he lies flat on the chemotherapy bed 101, and no longer applies a downward pressure to the pressure plate 203 and the return spring 204. The return spring 204 drives the pressure plate 203 and the return spring 204 to move. When the plate 203 returns to its original position, the pressure plate 203 resets and drives the plurality of tooth plates 107 to reset, so that the plurality of tooth plates 107 block the top of the movable groove 104 again, so that the vomit of the patient can be blocked to prevent the odor in the vomit from drifting into the surrounding environment. When the patient shows signs of vomiting and presses his elbow on the pressure plate, a series of mechanical actions can be quickly triggered to open the movable groove in a very short time, so that the patient can vomit in time, and avoid vomitus splashing everywhere due to not being able to find a suitable vomiting position in time, which increases the difficulty of cleaning and the discomfort of the patient. When the patient feels nauseous, he can quickly find a vomiting outlet, which reduces the patient's tension and anxiety and improves the patient's comfort during chemotherapy. After the patient finishes vomiting, the tooth plate can be quickly reset to block the top of the movable groove, effectively preventing the odor in the vomit from drifting into the surrounding environment, which is very important for keeping the air in the ward or treatment area fresh, not only making the patient feel more comfortable, but also reducing the adverse effects of the odor on other patients and medical staff.

[0031] After the patient vomits, the vomit is collected by the garbage bag, and the patient no longer applies downward pressure to the pressure plate 203. At this time, the annular block 214 moves upward to reset. After the annular block 214 is reset, the inclined groove 215 at the bottom of the annular block 214 no longer contacts the inclined block 212, and the extrusion force exerted on the telescopic spring 211 disappears, thereby forcing the circular rod 208 to drive the clamping block 209 to move outward. After the clamping block 209 moves outward, it no longer exerts a clamping force on the garbage bag. At this time, the garbage bag is affected by the weight of the vomit and will fall downward. The garbage bag falls downward on the top of the sealing plate 302. The sealing plate 302 is affected by the weight of the garbage bag and rotates with the V-shaped plate 301 as the midpoint. After the sealing plate 302 rotates, an extrusion force is exerted on the arc spring 303. At this time, a gap is formed between the sealing plate 302 and the cylinder 102, and the garbage bag falls to the bottom of the cylinder 102 through the gap. By opening the outer surface of the cylinder 102 The door on the wall can place the collection bucket on the bottom inner wall of the cylinder 102, so that the fallen garbage bag can fall directly into the collection bucket. When the garbage bag falls into the collection bucket, the pressure on the top of the sealing plate 302 disappears, and the arc spring 303 drives the sealing plate 302 back to its original position to seal the space between the cylinder 102 and the garbage bag. After the patient vomits, the garbage bag can automatically fall into the collection bucket, and there is no need to manually handle the garbage bag, which improves the efficiency of handling vomitus and reduces the contact between recycling personnel and garbage bags, thereby reducing the possibility of pathogens spreading from vomitus to recycling personnel. After the garbage bag is collected, the garbage bag is separated from the air at the top of the cylinder 102, which can effectively prevent the odor of vomitus in the garbage bag from emanating to the top of the cylinder 102. This can reduce the impact of odor on the staff when the staff puts on new garbage bags, providing a safer and more hygienic environment for patients and staff.
