Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a gastrointestinal lavage device. Background Technique

[0002] Gastric lavage refers to pouring a certain component of liquid into the gastric cavity, mixing the gastric contents and then pumping them out. This process is repeated multiple times. Its purpose is to remove the unabsorbed poisons in the stomach or clean the gastric cavity, and it is clinically used for the preparation before gastric surgery and examination.

[0003] In the traditional gastric lavage device, during the long-term gastric lavage process, it is necessary to replace the gastric lavage fluid container multiple times, that is, it is necessary to insert and remove the gastric lavage fluid container and the gastric lavage fluid suction pipe multiple times, and take and place the empty gastric lavage fluid container and the gastric lavage fluid container containing gastric lavage fluid multiple times. This will not only increase the labor intensity, but also produce a large number of empty gastric lavage fluid containers, resulting in a waste of medical resources.

[0004] Moreover, for the waste liquid container used to collect waste liquid, if it is similar to the gastric lavage fluid container, it will also be replaced multiple times during the long-term gastric lavage process, greatly increasing the medical cost. If it is similar to a water bucket, although the large volume of the water bucket can avoid the problem of multiple replacements, the opening of the water bucket is open, and it is easy to have the problem of environmental pollution caused by the odor of waste liquid.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 7 , a gastrointestinal cleaning device, including the main body 1 of the gastric lavage machine, the bench 2 and the containing bottle 3.

[0021] The gastric lavage fluid inlet on the main body 1 of the gastric lavage machine is connected to the gastric lavage fluid suction tube 102 through the first flexible tube 101. The gastric lavage fluid suction tube 102 can be inserted into the containing bottle 3 containing the gastric lavage fluid through the bottle mouth of the containing bottle 3. The gastric tube interface of the main body 1 of the gastric lavage machine is connected to the gastric tube. The waste liquid discharge port of the main body 1 of the gastric lavage machine is connected to the waste liquid discharge tube 104 through the second flexible tube 103. The waste liquid discharge tube 104 can be inserted into the empty containing bottle 3 through the bottle mouth.

[0022] The main body 1 of the gastric lavage machine pumps the gastric lavage fluid in the containing bottle 3 into the gastric tube and the stomach through the gastric lavage fluid inlet, the first flexible tube 101 and the gastric lavage fluid suction tube 102.

[0023] The main body 1 of the gastric lavage machine pumps the waste liquid in the stomach into the empty containing bottle 3 through the gastric tube, the waste liquid discharge port, the second flexible tube 103 and the waste liquid discharge tube 104.

[0024] The bench 2 is used to carry the main body 1 of the gastric lavage machine, and the bench 2 can move and brake on the ground. By moving and braking the bench 2, the main body 1 of the gastric lavage machine can be moved to different positions for use and storage.

[0025] The mouth of the containing bottle 3 is screwed with a connecting cylinder 31. At the upper opening of the connecting cylinder 31, a multi-petal elastic diaphragm 32 is connected. The multi-petal elastic diaphragms 32 are distributed in an annular array along the axial direction of the connecting cylinder 31. The multi-petal elastic diaphragms 32 cooperate together to form a sealing assembly capable of closing and opening the upper opening of the connecting cylinder 31, so as to isolate the mouth of the containing bottle 3 from the external environment, prevent the gastric lavage fluid in the containing bottle 3 from being polluted by the external environment of the bottle, or prevent the waste liquid in the containing bottle 3 from polluting the external environment of the bottle.

[0026] A double-station switching mechanism 4 is installed in the bench 2. On two moving platforms 41 whose positions can be exchanged in the double-station switching mechanism 4, a clamping platform 42 is respectively rotatably installed. Both clamping platforms 42 can be used to clamp the containing bottle 3 and make the mouth of the containing bottle 3 face upward.

[0027] The track plate 43 in the double-station switching mechanism 4 is vertically fixed in the bench 2, and at one end of the track plate 43 facing outside the bench 2, a track groove 44 is opened. The track groove 44 is in the shape of an inverted isosceles trapezoid with both ends flush and the middle concave.

[0028] One of the moving platforms 41 slides horizontally along the upper end of the track plate 43, and the other moving platform 41 slides along the track groove 44. During the sliding, the upper surfaces of both moving platforms 41 are kept parallel to the horizontal plane.

[0029] On both sides of the double-station switching mechanism 4 in the bench 2, a storage rack one 5 and a storage rack two 6 are respectively installed. The storage rack one 5 is used to store the containing bottles 3 containing waste liquid and the empty containing bottles 3, and the storage rack two 6 is used to hold the containing bottles 3 containing gastric lavage fluid.

[0030] After the empty containing bottle 3 is sent into the storage rack one 5 by the double-station switching mechanism 4, it receives the waste liquid discharged from the waste liquid discharge pipe 104, so as to prevent the clamping platform 42 from being polluted by the waste liquid and reduce the safety risk.

[0031] After the containing bottle 3 containing gastric lavage fluid is clamped and removed from the storage rack two 6 by the double-station switching mechanism 4, it cooperates with the gastric lavage fluid suction pipe 102.

[0032] As a further description of the double-station switching mechanism 4, as Figure 4 shown, the clamping platform 42 includes a rotating platform 421, a clamping plate 422 and a first spring column 423. Among them, the rotating platform 421 vertically penetrates and rotatably connects the moving platform 41. On the outer circumferential surface of the rotating platform 421 above the moving platform 41, a clamping plate 422 is fixedly connected. At one end of the clamping plate 422 away from the rotating platform 421, a "U"-shaped clamping groove is opened. The clamping plate 422 can be sleeved on the containing bottle 3 through the "U"-shaped clamping groove to realize the clamping of the containing bottle 3; On both sides of the clamping groove on the clamping plate 422, a first spring column 423 is slidably installed respectively. One ends of the two first spring columns 423 close to each other extend into the clamping groove, and the sliding directions of the two first spring columns 423 are distributed in a "V" shape pointing to the side away from the turntable 421. By moving the moving ends of the two first spring columns 423 to the position with the smallest distance, the accommodation bottle 3 in the clamping groove can be prevented from detaching. By moving the moving ends of the two first spring columns 423 to the position with the largest distance, a channel for the accommodation bottle 3 to move out of the clamping groove between the two first spring columns 423 can be provided.

[0033] During the process of the clamping table 42 taking out the accommodation bottle 3 containing gastric lavage fluid from the storage rack two 6 and moving the accommodation bottle 3 below the gastric lavage fluid suction pipe 102, the clamping plate 422 first moves towards the storage rack two 6 and makes the clamping groove face the storage rack two 6, pushing the two first spring columns 423 to contact the accommodation bottle 3 respectively and open with the movement of the clamping plate 422, so that the accommodation bottle 3 is stuck in the clamping groove between the turntable 421 and the first spring column 423. The two first spring columns 423 then close together, restricting the accommodation bottle 3 in the clamping groove. Then the clamping plate 422 moves towards the storage rack one 5 side, moving the accommodation bottle 3 below the gastric lavage fluid suction pipe 102.

[0034] During the process of the clamping table 42 moving the empty accommodation bottle 3 from below the gastric lavage fluid suction pipe 102 to below the waste liquid discharge pipe 104, the clamping table 42 moves towards the storage rack one 5 and rotates 180° during the movement, making the clamping groove face the storage rack one 5. Then, the empty accommodation bottle 3 is pushed into the storage rack one 5. After that, the clamping table 42 moves towards the storage rack two 6 side, making the two first spring columns 423 move relative to the accommodation bottle 3 and open with each other and then close together after detaching from the accommodation bottle 3.

[0035] After the clamping table 42 detaches from the empty accommodation bottle 3 and continues to move towards the storage rack two 6 side, the clamping table 42 can rotate 180°, making the clamping groove face the storage rack two 6 again.

[0036] As a further description of the double-station switching mechanism 4, such as Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, a first gear shaft 45 is fixedly connected to the lower end of a turntable 421 that slides along the upper end of a track plate 43, and a second gear shaft 46 is fixedly connected to the lower end of the turntable 421 that slides along a track groove 44. A first rack 47 and a second rack 48 are fixedly installed on the track plate 43. The first rack 47 cooperates with the first gear shaft 45 to achieve a 180° forward and reverse swing during the sliding process of the first gear shaft 45, and the second rack 48 and the second gear shaft 46 cooperate to achieve a 180° forward and reverse swing during the sliding process of the second gear shaft 46, so as to achieve a 180° forward and reverse swing when the two clamping platforms 42 reciprocally slide between a first storage rack 5 and a second storage rack 6, enabling the two clamping grooves to alternately face the first storage rack 5 and alternately face the second storage rack 6.

[0037] As Figure 3 shown in the figure, two lead screws 431 are respectively rotatably installed on both sides of the track plate 43. The threads on the two lead screws 431 have opposite helix directions, and the two lead screws 431 are driven by the same synchronous pulley and synchronous belt drive device and rotate synchronously in the same direction. The fixed part of the synchronous pulley and synchronous belt drive device is fixedly installed in the bench 2; A first sliding table 432 and a second sliding table 433 are respectively screwed onto the outer circumferential surfaces of the two lead screws 431. The first sliding table 432 is fixedly connected to a moving table 41 that slides along the upper end of the track plate 43. The second sliding table 433 is slidably installed on the track plate 43, and the second sliding table 433 penetrates along the central axis of the second gear shaft 46 and slidably connects with the second gear shaft 46 and the turntable 421.

[0038] The usage method of this gastrointestinal cleaning device is as follows: Step S1, make the clamping groove that slides along the upper end of the track plate 43 face the first storage rack 5, and the clamping groove that slides along the track groove 44 face the second storage rack 6, and no receiving bottle 3 is installed in both clamping grooves; at this time, the first rack 47 and the second rack 48 are located between the two clamping platforms 42; Step S2, fill the receiving bottle 3 containing gastric lavage fluid in the second storage rack 6, and install an empty receiving bottle 3 in the clamping groove facing the first storage rack 5; Step S3, drive the two lead screws 431 to rotate simultaneously in the first direction through the synchronous pulley and synchronous belt drive device, move the two moving tables 41 away from each other, make the clamping platform 42 with the receiving bottle 3 extend into the first storage rack 5, cooperate with the first storage rack 5 to place the empty receiving bottle 3 in the first storage rack 5, and make the bottle mouth of the empty receiving bottle 3 face the waste liquid discharge pipe 104, make the clamping platform 42 with the empty clamping groove extend into the second storage rack 6, and sleeved the receiving bottle 3 containing gastric lavage fluid through the empty clamping groove; at this time, the first rack 47 and the second rack 48 are still located between the two clamping platforms 42; Step S4, drive two lead screws 431 to rotate simultaneously in the second direction through a synchronous pulley and synchronous belt drive device, so that the two clamping platforms 42 approach each other, move the clamping platform 42 extending into the first storage rack 5 out of the first storage rack 5, move the clamping platform 42 extending into the second storage rack 6 out of the second storage rack 6, and move a containing bottle 3 containing gastric lavage fluid from the second storage rack 6 to below the gastric lavage fluid suction pipe 102. Then, make the two clamping platforms 42 stationary; at this time, the first rack 47 and the second rack 48 are still located between the two clamping platforms 42; Step S5, insert the gastric lavage fluid suction pipe 102 into the containing bottle 3 containing gastric lavage fluid, insert the waste liquid discharge pipe 104 into the empty containing bottle 3, and insert the gastric tube into the gastric cavity; then, alternately pump the gastric lavage fluid into the gastric cavity and pump the waste liquid in the stomach into the containing bottle 3 through the main body 1 of the gastric lavage machine; Step S6, after the use of the gastric lavage fluid in one containing bottle 3 is completed, pause the main body 1 of the gastric lavage machine, and pull out the gastric lavage fluid suction pipe 102 and the waste liquid discharge pipe 104 from the corresponding containing bottle; Step S7, drive two lead screws 431 to rotate simultaneously in the second direction through a synchronous pulley and synchronous belt drive device, so that the two clamping platforms 42 approach each other and then move away from each other, move the clamping platform 42 with the original clamping groove facing the first storage rack 5 to the side of the second storage rack 6, and rotate 180 degrees through the cooperation of the first gear shaft 45 and the first rack 47 during the movement, so that the clamping groove on the clamping platform 42 faces the second storage rack 6, and make the clamping platform 42 sleeved on the containing bottle 3 containing gastric lavage fluid through the clamping groove; Move the clamping platform 42 clamping the originally empty containing bottle 3 after containing gastric lavage fluid along the track groove 44 to the first storage rack 5, and rotate 180° through the cooperation of the second gear shaft 46 and the second rack 48 during the movement, turn the containing bottle 3 towards the first storage rack 5, then, put the containing bottle 3 into the first storage rack 5, and push the containing bottle 3 located below the waste liquid discharge pipe 104 in the first storage rack 5 deeper into the first storage rack 5; Step S8, repeat steps S4, S5, S6, and S7.

[0039] Through the above steps, multiple containing bottles 3 containing gastric lavage fluid are pre-stored in the second storage rack 6, and then, are sequentially moved to the position of the gastric lavage fluid suction pipe 102, and the gastric lavage fluid is emptied to form an empty containing bottle 3. The empty containing bottle 3 is then moved to the position of the waste liquid discharge pipe 104 to receive waste liquid, realizing the automatic movement and feeding of the containing bottle 3, realizing the reuse of the containing bottle 3, saving medical resources, and reducing medical costs.

[0040] It should be noted that the first direction and the second direction are opposite, that is, when the first direction is the clockwise direction, the second direction is the counterclockwise direction; conversely, when the first direction is the counterclockwise direction, the second direction is the clockwise direction.

[0041] It should be noted that the gastric lavage fluid suction pipe 102 and the waste liquid discharge pipe 104 are driven by the same lifting device to move up and down synchronously, so as to realize the automatic insertion and extraction of the gastric lavage fluid suction pipe 102 into and out of the containing bottle 3, and the automatic insertion and extraction of the waste liquid discharge pipe 104 into and out of the containing bottle 3, avoiding manual insertion and extraction of the gastric lavage fluid suction pipe 102 and the waste liquid discharge pipe 104, reducing the labor intensity, and avoiding the risk of waste liquid pollution caused by manual insertion and extraction.

[0042] As Figure 1 shown, the lifting device includes a lifting unit 7 and a sliding rod 8. The installation part of the lifting unit 7 is fixedly installed on the bench 2, and the output end of the lifting unit 7 is fixedly connected to the sliding rod 8. The sliding rod 8 is driven by the lifting unit 7 to move up and down; the sliding rod 8 is fixedly connected to the gastric lavage fluid suction pipe 102 and the waste liquid discharge pipe 104, so that the gastric lavage fluid suction pipe 102 and the waste liquid discharge pipe 104 can be driven by the lifting unit 7 to move up and down simultaneously, realizing the automatic insertion and extraction of the gastric lavage fluid suction pipe 102 and the waste liquid discharge pipe 104.

[0043] The lifting unit 7 can be an electric push rod, a linear rotary drive unit module, a hydraulic cylinder or other devices capable of outputting linear movement in the prior art. The sliding rod 8 can be slidably installed on the bench 2.

[0044] As a further description of a gastrointestinal lavage device of the present invention, as Figure 4 shown, the first storage rack 5 includes an arc-shaped trough rack 51 and a straight trough rack 52 that are interconnected. One end of the straight trough rack 52 away from the arc-shaped trough rack 51 is open as the entrance of the containing bottle 3.

[0045] A through hole for the containing bottle 3 to move out of the arc-shaped trough rack 51 from top to bottom is provided on one side of the arc-shaped trough rack 51 away from the straight trough rack 52. A storage bucket 9 is arranged below the through hole. The storage bucket 9 is detachably installed in the bench 2 through a bolt, as Figure 2 shown. The storage bucket 9 can collect a plurality of containing bottles 3 and can pour out the containing bottles 3 in a dumping manner, avoiding direct contact between medical staff and the containing bottles containing waste liquid.

[0046] The first storage rack 5 further includes a guide rod 53 fixed in the bench 2. A peeling block 54 is slidably sleeved on the guide rod 53. The peeling block 54 is used to peel the empty containing bottle 3 from the clamping table 42; Specifically, during the process of the containing bottle 3 entering the first storage rack 5, the containing bottle 3 first enters the straight trough rack 52, pushing the peeling block 54 to move up. After the containing bottle 3 moves below the waste liquid discharge pipe 104, the peeling block 54 moves up to the highest position and then moves down to contact the side of the containing bottle 3 close to the moving table 41, as Figure 4 shown; Then, as the mobile station 41 drives the clamping table 42 to move away from the storage rack 1 5, the accommodating bottle 3 is restricted by the peeling block 54 and cannot move out of the storage rack 1 5 accordingly. This enables the clamping table 42 to move relative to the accommodating bottle 3, driving the movable ends of the two first spring columns 423 to extend into the clamping plate 422 and move away from each other to form a channel for the accommodating bottle 3 to pass through, thus realizing the separation from the accommodating bottle 3.

[0047] The automatic separation between the empty accommodating bottle 3 and the clamping plate 422 is achieved through the storage rack 1 5, realizing the collection of the accommodating bottle 3. Through the cooperation of the storage rack 1 5 and the lifting device, the automatic insertion and extraction between the accommodating bottle 3 and the waste liquid discharge pipe 104 are realized. By making the clamping table 42 slide along the track plate 43 and performing the insertion and extraction of the waste liquid discharge pipe 104 after the clamping table 42 is separated from the accommodating bottle 3, a small amount of waste liquid that may fall from the waste liquid discharge pipe 104 will not fall on the clamping table 42, avoiding the contamination of the clamping table 42 by the waste liquid, thereby reducing the pollution risk.

[0048] In the prior art, for example, a gastric lavage device for automatically switching gastric lavage collection bottles disclosed in a Chinese invention patent with the publication number CN113289113A realizes the temporary storage of the bottle body through a rotating turntable and the position switching of the bottle body between the sewage discharge position and the gastric lavage aspiration position. Although the reuse of the bottle body can also be achieved and the medical cost can be reduced, the turntable rotates continuously at the sewage discharge position and the gastric lavage aspiration position, and medical staff need to directly install the bottle body containing gastric lavage on the turntable. It is easy for the waste liquid falling from the sewage discharge position to contaminate the turntable, and then contaminate the bottle body containing gastric lavage and contaminate the medical staff, resulting in a relatively high medical risk.

[0049] It should be noted that the accommodating bottle 3 containing waste liquid in the storage rack 1 5 will gradually penetrate into the arc-shaped trough rack 51, move away from the waste liquid discharge pipe 104, and finally fall into the storage barrel 9 through the through hole as the empty accommodating bottle 3 is continuously fed into the straight trough rack 52.

[0050] As Figure 2 shown, the part of the storage barrel 9 in contact with the outer circumferential surface of the accommodating bottle 3 is in a C-shaped tubular structure, and the opening can be expanded to facilitate the removal of the accommodating bottle 3 from the storage barrel 9 through the expanded opening.

[0051] As a further description of a gastrointestinal cleaning device of the present invention, as Figure 5 、 Figure 6 、 Figure 7 and Figure 8 shown, the storage rack 2 6 includes a bottle box 61, a bottle rack 62, a guide plate 63 and a bottle pushing mechanism; Among them, the bottle box 61 is fixedly installed in the table frame 2. The upper end of the bottle box 61 is open, and an outlet for the accommodating bottle 3 to move out of the bottle box 61 is provided on the side surface of the bottle box 61. The bottle rack 62 is columnar with a smaller bottom and a larger top. The bottle rack 62 can rotate around its own central axis. The smaller-diameter end of the bottle rack 62 is the small end, and the larger-diameter end is the large end. The large end of the bottle rack 62 is located above the bottle box 61, and a plurality of bottle-holding cavities are provided inside, and the plurality of bottle-holding cavities are evenly spaced along the circumferential direction of the bottle rack 62; the small end of the bottle rack 62 extends downward and is rotatably installed on the platform 2 through a bearing; By rotating the bottle rack 62, a plurality of bottle-holding cavities can be sequentially moved above the bottle box 61, so that a plurality of receiving bottles 3 on the bottle rack 62 can sequentially fall into the inner cavity of the bottle box 61; The guide plate 63 is fixed to the platform 2. The guide plate 63 is located between the lower part of the bottle-holding cavity and the bottle box 61, and a guide hole for the receiving bottle 3 to pass through is provided on the guide plate 63; after the bottle-holding cavity is aligned with the guide hole, the receiving bottle 3 in the bottle-holding cavity moves downward under its own gravity, passes through the guide hole, and enters the inner cavity of the bottle box 61; The bottle pushing mechanism is used to drive the bottle rack 62 to rotate, and after any one of the bottle-holding cavities moves above the guide hole, it pushes the receiving bottle 3 located below the guide hole to move towards the outlet, vacating the inner cavity of the bottle box 61 below the guide hole, so that when the receiving bottle 3 on the bottle rack 62 beside the guide hole moves above the guide hole, it can fall into the inner cavity of the bottle box 61 through the guide hole.

[0052] The bottle pushing mechanism includes a gear 621, a driving disk 64, a bottle pushing block 65, a bottle pushing rod 66, and a rotation driving unit 67.

[0053] Among them, the gear 621 is coaxially fixed to the lower end of the small end of the bottle rack 62. A driving disk 64 is arranged beside the gear 621. The driving disk 64 can rotate around its own central axis. A plurality of arc-shaped racks are evenly spaced along the circumferential direction on the outer circumferential surface of the driving disk 64. The plurality of arc-shaped racks are sequentially engaged with the gear 621 during the rotation of the driving disk 64, driving the bottle rack 62 to rotate intermittently with a rotation amplitude of 360° / the number of arc-shaped racks for a single rotation; The upper end of the driving disk 64 is provided with a "plum blossom"-shaped driving groove. The "petals" of the "plum blossom"-shaped driving groove have the same odd number as the arc-shaped racks. The "petals" and the arc-shaped racks are in one-to-one correspondence in position, and the position-corresponding "petals" and arc-shaped racks have the same symmetry plane. The connection part between two adjacent "petals" is in an arc-shaped groove structure concentric with the driving disk 64; Furthermore, as Figure 8 shown, the sector angle formed by clamping two adjacent "petals" is a, the sector angle swept by a single arc-shaped rack is b, the sector angle swept by a single "petal" is c, and the sector angle of a single arc-shaped groove structure is d. a = 360° / the number of "petals", a = c + d, c < d, b < c / 2 < d; And before use, as Figure 6As shown, the bottle pushing rod 66 is located within one "petal" of the driving groove and at the farthest position from the central axis of the driving disk 64. The bottle pushing block 65 is located outside the inner cavity of the bottle box 61, and the gear 621 is located exactly in the middle between two adjacent arc-shaped racks.

[0054] The bottle pushing block 65 is slidably mounted on the bottle box 61, and one end of the bottle pushing block 65 can enter and exit the inner cavity of the bottle box 61 to push the accommodating bottle 3 away from below the guide hole and move it towards the outlet, and at the same time create a space below the guide hole that can accommodate the accommodating bottle 3. The other end of the bottle pushing block 65 is fixedly connected to a bottle pushing rod 66. The bottle pushing rod 66 is vertically arranged and slidably connected to the bench 2. The lower end of the bottle pushing rod 66 extends into the driving groove. By the rotation of the driving disk 64, the intermittent rotation of the bottle rack 62 is realized, and after each rotation of the bottle rack 62, the bottle pushing block 65 enters and exits the bottle box 61, realizing the movement of the accommodating bottle 3 from the bottle rack 62 to the bottle box 61, and realizing the movement of the accommodating bottle 3 from below the guide hole to the outlet. The lower end of the driving disk 64 is fixedly connected to the output end of the rotation driving unit 67. The fixed part of the rotation driving unit 67 is fixedly connected to the bench 2. The rotation driving unit 67 is used to drive the driving disk 64 to rotate. The rotation driving unit 67 is a power device such as a motor or a motor in the prior art that can directly output rotational motion.

[0055] After the clamping table 42 clamps an accommodating bottle 3 containing gastric lavage fluid from the outlet of the bottle box 61, the inner cavity of the bottle box 61 corresponding to the outlet becomes empty. Then, the rotation driving unit 67 is started to drive the driving disk 64 to rotate, so that the bottle pushing rod 66 moves from the position farthest from the central axis of the driving disk 64 in the "petal" to the confluence of the "petal" and the arc-shaped groove structure, and pushes the bottle pushing block 65 to slide deeply into the inner cavity of the bottle box 61, pushing the accommodating bottle 3 below the guide hole towards the outlet, and making the arc-shaped rack rotate close to the gear 621. Then, the driving disk 64 continues to rotate, the bottle pushing rod 66 moves in the arc-shaped groove structure and approaches the next "petal", driving the arc-shaped rack to rotate and engage with the gear 621, driving the bottle rack 62 to rotate, so that the accommodating bottle 3 located beside the guide hole moves above the guide hole. Then, the arc-shaped rack disengages from the gear 621, making the bottle rack 62 stationary, and the accommodating bottle 3 falls on the upper surface of the bottle pushing block 65 under its own gravity. Then, the driving disk 64 continues to rotate, making the bottle pushing rod 66 move into the next "petal" and be located at the position farthest from the central axis of the driving disk 64 in this "petal", driving the bottle pushing block 65 to move out of the inner cavity of the bottle box 61, and the accommodating bottle 3 falls completely into the bottle box 61 smoothly. Then, the driving disk 64 stops, and at this time, the gear 621 is again located between two adjacent arc-shaped racks.

[0056] The storage rack two 6 stores and conveys the accommodation bottles 3, enabling multiple accommodation bottles 3 containing gastric lavage fluid to be temporarily stored at one time before use, and enabling the automatic movement of the accommodation bottles 3 containing gastric lavage fluid to the lower part of the gastric lavage fluid suction pipe 102. The placement speed of the accommodation bottles 3 in the storage rack two 6 is not affected by the insertion and extraction speed at the gastric lavage fluid suction pipe 102, and the medical staff can be kept away from the gastric lavage fluid suction pipe 102 to avoid cross-contamination among the medical staff, the gastric lavage fluid suction pipe 102, and the accommodation bottles 3.

[0057] It should be noted that during the rotation of the bottle rack 62, to ensure that the bottle loading cavity can be aligned with the guide hole, a spring post two 622 is embedded at one end of the bottle rack 62 facing the guide disk 63. The guide disk 63 is provided with a number of limit grooves equal to the number of bottle loading cavities, and the movable end of the spring post two 622 can be inserted and removed into the limit grooves. By inserting the movable end of the spring post two 622 into the limit grooves, the positioning of the bottle rack 62 is achieved.
