Description

Technical Field

[0001] The invention belongs to the field of negative pressure suction tube flushing, and in particular relates to a medical negative pressure flushing device. Background Art

[0002] Sputum suction is a common treatment technique in clinical practice, and is often used for patients with decreased spontaneous breathing function, weakened or absent cough reflex, etc. Sputum suction is an important measure to protect the airway of respiratory patients. The device used is a negative pressure device connected to a negative pressure suction tube placed beside the bed for standby use. When the patient needs sputum suction, the disposable sputum suction tube is connected to complete the operation.

[0003] After each suction, a small amount of sputum will remain in the negative pressure suction tube, which will cause the reproduction of pathogens, and the suction tube must be fully rinsed. Clinically, after suction, according to the principle of aseptic operation, the normal saline for flushing is poured into the prepared disposable medicine cup in advance, 30-50ml each time, the suction tube and the negative pressure suction tube are separated, the suction tube is discarded, and the joint of the negative pressure suction tube is immersed in the medicine cup with normal saline for negative pressure flushing. A medicine cup can only be used once. If it needs to be flushed again, the medicine cup needs to be replaced until the pipe is flushed clean. Finally, the joint of the suction tube is inserted into the interface at the top of the sputum collection bag and dried for storage. Although this method prevents contamination in the suction tube very well, it is time-consuming and labor-intensive, inconvenient to operate, and not environmentally friendly.

When the rotating disk 6 rotates, the medicine cup 2 passes through the negative pressure suction tube 10, the flushing device, and the dosing device in sequence. The sealing component 3 is arranged at the bottom of the medicine cup 2 to seal the bottom opening of the medicine cup 2, and when the medicine cup 2 moves to below the flushing device, the sealing component 3 releases the seal.

[0026] During the specific implementation, the negative pressure suction tube 10 is inserted downward into the medicine cup 2 where there is no other equipment above, and the other end of the negative pressure suction tube 10 is connected to the negative pressure equipment. The negative pressure equipment can be started to suck the cleaning solution into the negative pressure suction tube 10 for cleaning. After the cleaning solution in the medicine cup 2 is drained, the cleaning of the negative pressure suction tube 10 is completed. After completion, the driving device 8 is started, and the medicine cup 2 rotates sequentially. The rotation angle is the central angle between two adjacent medicine cups 2. The evacuated medicine cup 2 is cleaned by the flushing device to clean the residual medicine liquid on the inner wall of the medicine cup 2, and then the new cleaning solution is injected into the medicine cup 2 through the dosing device. When the medicine cup 2 is added with medicine and the negative pressure suction tube 10 is cleaned, the sealing component 3 seals the opening at the bottom of the medicine cup 2; when the medicine cup 2 is cleaned, the sealing component 3 releases the seal and the flushing water flows downward. Compared with the prior art, the present invention realizes the cleaning, adding and cleaning of the medicine cup 2 and the negative pressure suction tube 10 in sequence through the rotation of multiple medicine cups 2. The operation is simple and quick. No external factors contact the medicine cup 2 during the process. It is safer and more reliable and can avoid pollution. Moreover, the medicine cup 2 can be reused many times, which is more environmentally friendly.

[0027] Specifically, Figure 3 Preferably, two flushing devices are provided, that is, the medicine cup 2 needs to be flushed by two flushing devices. Through the secondary cleaning method, the medicine cup 2 can be cleaned more thoroughly.

[0029] In addition, other implementations may be adopted to adjust the number of medicine cups 2, flushing devices and dosing devices.

[0030] Furthermore, it also includes a box body 1, the top opening of the box body 1 is detachably connected to the cover plate 9, the rotating disk 6 and the medicine cup 2 are arranged in the box body 1, and the box body 1 and the cover plate 9 form a sealing structure to prevent external factors from contaminating the medicine cup 2.

[0031] Furthermore, the flushing device includes a flushing pipe 11, which is fixed on the cover plate 9, and its bottom passes through the cover plate 9 and is provided with a nozzle. The flushing pipe 11 is connected to a water supply device, and the water supply device is a prior art, such as a combination of a water pump and a water tank. Cleaning water is injected into the flushing pipe 11 and sprayed into the medicine cup 2 in a fan-shaped spray manner through the nozzle for flushing.

[0032] Furthermore, the dosing device includes a dosing pipe 14, which is fixed on the cover plate 9, and its bottom passes through the cover plate 9 and is provided with a nozzle. The dosing pipe 14 is connected to a drug supply device, and the drug supply device is a prior art, such as a combination of a water pump and a water tank. The cleaning solution is injected into the dosing pipe 14 and sprayed into the medicine cup 2 in a straight line through the nozzle, and the sprayed amount just fills the medicine cup 2.

[0033] Furthermore, the driving device 8 is a motor, which is installed on the top of the cover plate 9, and its output end is fixedly connected to the main shaft 5. The rotating disk 6 is fixed on the main shaft 5. The side of the rotating disk 6 is connected to the medicine cup 2 through a clamping ring 7. The clamping ring 7 is sleeved on the medicine cup 2 and can be detachably connected to the medicine cup 2. The side of the clamping ring 7 is fixedly connected to the outer side of the rotating disk 6.

[0034] The connection between the clamp ring 7 and the medicine cup 2 can be screws, buckles, etc., which are easy to dismantle and can remove the medicine cup 2 to achieve the purpose of replacing the medicine cup 2.

[0035] Furthermore, a filter screen 12 is arranged in the box body 1, a drainage cavity is formed below the filter screen 12, and a drainage pipe 13 connected to the drainage cavity is arranged on the side of the box body 1. The function of the filter screen 12 is to filter impurities in the flushing water during flushing and perform preliminary treatment on the wastewater.

[0037] The bottom of the connecting rod 304 is connected to a lifting component for pushing the connecting rod 304 up and down. When the medicine cup 2 is located directly below the flushing device, the lifting component pushes the connecting rod 304 to move downward, so that the waist-shaped hole 303 is separated from the opening at the bottom of the medicine cup 2. During the lifting process of the connecting rod 304, the plug 301 is always located in the opening at the bottom of the medicine cup 2.

[0038] Furthermore, the lifting component is an annular guide rail 4, which is annular and includes an elevated section 401 with the same height as the elevated section 401, and a descending section 403 with a height lower than the elevated section 401;

The connecting rod 304 is rotatably connected to a rotating rod 305, and the two ends of the rotating rod 305 are slidably connected to the outer rail 4A and the inner rail 4B respectively.

[0042] like Figure 3 In (a), the inner diameter of the outer rail 4A is larger than the outer diameter of the inner rail 4B, and the two annular guide rails 4 can constrain the two ends of the connecting rod 304, better limit the connecting rod 304, and make the lifting of the plug 301 more stable. Annular grooves can be respectively provided on the inner side of the outer rail 4A and the outer side of the inner rail 4B, and the two ends of the rotating rod 305 are inserted into the annular grooves of the outer rail 4A and the inner rail 4B to realize the vertical constraint.
