[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-9 A waste liquid collection device for medical care shown in the figure comprises a mobile base 1 and a cabinet 2 fixedly connected to the mobile base 1. A liquid suction mechanism 3 for absorbing waste liquid is provided on the cabinet 2. The liquid suction mechanism 3 is mainly composed of a pump body, a liquid suction head and backwashing components. It is a mature technology in the prior art and will not be described in detail here. An L-shaped tube 4 is fixedly connected to the top of the cabinet 2, and one end of the L-shaped tube 4 is fixedly connected to the liquid outlet end of the liquid suction mechanism 3. A fixed rod 5 is fixedly connected to the top of the mobile base 1. A cylinder 6 is rotatably connected to the top of the outer wall of the fixed rod 5, and a top cylinder 8 is provided on the inner side of the cylinder 6. When the waste liquid collection device is used, the device is first pushed to the location where the waste liquid needs to be collected through the mobile base 1, and then the medical staff inserts the pipette head into the waste liquid and starts the pipette mechanism 3. Then, under the action of the pump body and the transmission of the L-shaped tube 4, the bellows 27 and the conical rubber head 20, the waste liquid is sucked into the collection tube 13.

[0021] The outer wall of the cylinder 6 is fixedly connected to a circular frame 11 through four support rods 10, and the cross-section of the circular frame 11 is U-shaped, which is convenient for the residual waste liquid in the conical rubber head 20 to drip into the circular frame 11 during the conversion process, and to be collected and processed to avoid dripping on the ground, and to facilitate subsequent cleaning. A plurality of liquid inlet cylinders 12 are equidistantly fixedly connected to the top of the circular frame 11, and a collecting cylinder 13 is provided below the circular frame 11 and at a position corresponding to the liquid inlet cylinder 12. A mounting structure for mounting the collecting cylinder 13 is provided below the circular frame 11, and a push rod 9 is slidably connected to the inner side of the top cylinder 8. The inner side of the cylinder 6 and the liquid inlet cylinder 12 are provided with straight grooves 14 at corresponding positions, and oblique grooves 15 are provided between the straight grooves 14, and the top ends of the straight grooves 14 are provided with inwardly sunken grooves 16, and the connection between the grooves 16 and the oblique grooves 15 is inclined, and the push rod 9 is inserted into the inner side of the groove 16, and an upper spring 17 is fixedly connected between the outer wall of the push rod 9 and the inner side of the top tube 8, and the push rod 9 is conveniently pushed into the groove 16 through the upper spring 17, and the two ends of the oblique groove 15 are connected with the upper and lower ends of the two adjacent straight grooves 14, and the side wall of the push rod 9 is set as a smooth arc surface, so that the push rod 9 can slide out of the groove 16 better, thereby improving the silkiness during the operation of the device; A U-shaped seat 18 is fixedly connected to the top of the cabinet 2, and a sliding plate 19 is slidably connected to the inner side of the U-shaped seat 18. A conical rubber head 20 is fixedly connected to the top of the sliding plate 19 and is located above one of the liquid inlet cylinders 12. The setting of the conical rubber head 20 can ensure the sealed connection between the bellows 27 and the liquid inlet cylinder 12, avoid spilling of waste liquid, and improve the collection effect of the device. A conversion mechanism for alternately pushing the sliding plate 19 and the top cylinder 8 to slide downward is provided above the annular frame 11. A bellows 27 is fixedly connected between the top of the conical rubber head 20 and the other end of the L-shaped tube 4. The setting of the bellows 27 not only ensures the communication between the conical rubber head 20 and the L-shaped tube 4, but also stretches when the conical rubber head 20 moves downward to avoid hindering the movement of the conical rubber head 20. The conversion mechanism includes an electric telescopic cylinder 21, a pair of which are provided, and the electric telescopic cylinders 21 are fixedly connected to the top of the cabinet 2, the output ends of the electric telescopic cylinders 21 are fixedly connected to connecting rods 22, upper right-angle blocks 23 are fixedly connected between the connecting rods 22, the side wall of the sliding plate 19 is fixedly connected to the lower right-angle block 24, and three lower springs 25 are fixedly connected between the inner side of the U-shaped seat 18 and the top of the sliding plate 19; Round rods 26 are fixedly connected to both sides of the outer wall of the top cylinder 8, and conversion right-angle blocks 28 are fixedly connected to the side walls of the connecting rod 22 and the positions corresponding to the round rods 26. Side frames 32 are fixedly connected to both sides of the top of the cabinet 2, and a blocking mechanism for blocking the liquid inlet cylinder 12 is provided on the annular frame 11; During the use of the collecting device, when the collecting tube 13 is full or other medicines need to be collected and classified, the electric telescopic cylinder 21 can be controlled to start and drive the connecting rod 22 to slide, thereby driving the upper right-angle block 23 to gradually move out from above the lower right-angle block 24, thereby gradually releasing the squeezing of the lower right-angle block 24, and then pulling the sliding plate 19 to slide on the inner side of the U-shaped seat 18 under the elastic force of the lower spring 25, and driving the conical rubber head 20 to be pulled out of the liquid inlet cylinder 12, and then under the continued driving of the electric telescopic cylinder 21, the conversion right-angle block 28 on the side wall of the connecting rod 22 is driven to move above the round rod 26, so that the round rod 26 is gradually squeezed downward by the inclined surface of the conversion right-angle block 28 to slide, and the top tube 8 and the rectangular frame 38 are driven to slide on the rectangular rod 7, and the return spring 29 is gradually compressed downward; At the same time, the push rod 9 in the initial position is located in the groove 16. Since there is a step between the groove 16 and the straight groove 14 and the top cylinder 8 can only slide up and down, the cylinder 6 will be driven to rotate on the fixed rod 5 under the thrust of the push rod 9, and the annular frame 11 and multiple collecting cylinders 13 will be driven to rotate through the support rod 10, and at the same time, the push rod 9 will gradually slide out of the groove 16 and slide into the inclined groove 15, and squeeze the push rod 9 outward to stretch the upper spring 17, and then under the squeezing of the push rod 9, the collecting cylinder 13 collected under the conical rubber head 20 will be turned away, and the new collecting cylinder 13 will be turned to the bottom of the conical rubber head 20. At the same time, the push rod 9 will move out of the inclined groove 15 and slide into another straight groove 14, and then the electric telescopic cylinder 21 can be controlled to repeat. The upper right-angle block 23 is moved to the side of the lower right-angle block 24 under the drive of the electric telescopic cylinder 21, and then the inclined surface of the upper right-angle block 23 squeezes the inclined surface of the lower right-angle block 24, so that the sliding plate 19 gradually slides downward and gradually stretches the lower spring 25, and drives the conical rubber head 20 to be inserted into the replaced liquid inlet cylinder 12, thereby completing the automatic conversion of the collecting cylinder 13.

[0022] In order to improve the stability of the device during operation, a rectangular rod 7 is fixedly connected to the top of the fixed rod 5 and located on the inner side of the cylinder 6, and a rectangular frame 38 is fixedly connected to the top end of the top cylinder 8, and the rectangular frame 38 is slidably connected to the outer wall of the rectangular rod 7. Through the setting of the rectangular rod 7 and the rectangular frame 38, the up and down sliding position of the top cylinder 8 can be restricted, thereby ensuring that the push rod 9 can only slide up and down to squeeze the cylinder 6 for rotation, thereby improving the stability of the device during operation. A reset spring 29 is fixedly connected between the top end of the top cylinder 8 and the top of the rectangular rod 7. Through the setting of the reset spring 29, it is convenient to push the top cylinder 8 to slide upward for reset.

[0023] In order to facilitate the subsequent removal of collected waste liquid for treatment, the installation structure includes a threaded barrel 30, and a plurality of threaded barrels 30 are provided, and the threaded barrels 30 are all fixedly connected to the bottom of the liquid inlet barrel 12, and the top of the collecting barrel 13 is threadedly connected to the inner side of the threaded barrel 30. During installation, the collecting barrel 13 can be inserted into the collecting bag and the collecting bag can be fixed. During subsequent installation, the collecting barrel 13 can be inserted into the bottom of the threaded barrel 30. Subsequently, during the collection process, the waste liquid entering from the liquid inlet barrel 12 will be discharged into the collecting bag, which is convenient for subsequent removal and treatment. The above operation is repeated in reverse during disassembly.

[0024] In order to be able to automatically block the liquid inlet cylinder 12 on a plurality of unused collection cylinders 13, the blocking mechanism includes a blocking right-angle block 31, a pair of blocking right-angle blocks 31 are provided, and the blocking right-angle blocks 31 are fixedly connected to the side away from the connecting rod 22, a three-quarter circular connecting ring 33 is provided at the top of the annular frame 11, side plates 34 are fixedly connected to the top of the connecting ring 33 on both sides, and the side plates 34 are slidably connected to the side walls of the side frame 32, a conical rubber plug 35 is fixedly connected to the bottom of the connecting ring 33 and the corresponding position of the liquid inlet cylinder 12, an extrusion right-angle block 36 is fixedly connected to the side close to the side plate 34, and the inclined surface of the blocking right-angle block 31 is fitted with the inclined surface of the extrusion right-angle block 36, and a plurality of extrusion springs 37 are fixedly connected between the top end of the side frame 32 and the top of the side plate 34, and the conical rubber plug 35 is conveniently pushed out of the liquid inlet cylinder 12 quickly through the provision of the extrusion spring 37; During the operation of the conversion mechanism, when the electric telescopic cylinder 21 pushes the connecting rod 22 and the upper right-angle block 23 to slide out from above the lower right-angle block 24 to release the squeezing of the conical rubber head 20, the blocking right-angle blocks 31 on both sides of the connecting rod 22 will gradually slide away from the inclined surface of the squeezing right-angle block 36, thereby gradually releasing the squeezing of the squeezing right-angle block 36, and then the side plate 34 is pulled upward by the elastic force of the squeezing spring 37, and at the same time, the connecting ring 33 and the conical rubber plug 35 are pulled out from the other several liquid inlet cylinders 12, so that the squeezing of the other several liquid inlet cylinders 12 can be released. The blocking of the collecting cylinder 13 facilitates the subsequent position conversion of the collecting cylinder 13. Then, the blocking right-angle block 31 is removed from the extruding right-angle block 36. Then, when the connecting rod 22 is reset after the conversion is completed, the blocking right-angle block 31 is driven to move to the side of the extruding right-angle block 36, and then the blocking right-angle block 31 is gradually squeezed downward by the inclined surface to make the extruding right-angle block 36 slide downward, and the extrusion spring 37 is gradually stretched, so that multiple conical rubber plugs 35 are inserted above the converted liquid inlet cylinder 12 to ensure that the smell of the waste liquid in the collecting cylinder 13 will not spread.
