Description

Technical Field

[0001] This invention relates to the field of electric suction device technology, and more particularly to an electric suction device that is easy to clean. Background Technology

[0002] Electric suction devices are important medical equipment primarily used to quickly and efficiently remove blood, secretions, body fluids, or other obstructions from a patient's body during surgery or emergency procedures, ensuring a clear airway or a clear surgical field. Their core function is to use negative pressure suction to remove liquids or semi-solid substances from body cavities or wounds. They are widely used in surgery, obstetrics, otolaryngology, anesthesiology, and intensive care.

[0003] Existing electric suction devices have shortcomings in use. First, they cannot automatically clean buffer bottles and collection containers, requiring manual handling, which is not only inefficient but also increases the risk of infectious disease transmission. Second, their disinfectant solutions cannot effectively disinfect buffer bottles and collection containers. Therefore, the inventors aim to optimize and improve existing electric suction devices. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems in conventional technology and provide an electric suction device that is easy to clean.

[0005] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: An easy-to-clean electric suction device includes a mobile trolley, a suction device body, a positioning seat, a buffer bottle, a collection container bottle, an overflow prevention cap, and a cleaning assembly. The suction device body and the positioning seat are mounted on the upper side of the trolley's platform. The buffer bottle with an overflow prevention cap, the collection container bottle, and the cleaning assembly for cleaning the buffer bottle and the collection container bottle are snapped onto the upper side of the positioning seat. The cleaning assembly includes an outer box and a horizontal support plate mounted above it. The outer box contains two sets of disinfectant storage cylinders and a waste liquid cylinder. The front panel of the outer box has a replenishment pipe for adding disinfectant to the storage cylinders and a drain pipe for discharging waste liquid from the waste liquid cylinders. The upper panel of the outer box has a waste liquid guide pipe extending into the waste liquid cylinder and a disinfectant pumping pipe extending into the disinfectant storage cylinder. The waste liquid guide pipe, embedded in the horizontal support plate, is connected to a waste liquid suction pipe. The disinfectant pumping pipe, embedded in the horizontal support plate, is connected to a protruding pipe. The bottom end of the protruding pipe is connected to the cleaning pipe via a liquid-guiding slip ring. Multiple nozzles are located on the outside of the cleaning pipe, and a baffle for achieving self-rotation is installed on the outside of the nozzles.

[0006] Furthermore, in the aforementioned easy-to-clean electric suction device, a first pump body connected to a disinfectant pumping pipe is installed inside the disinfectant storage cylinder, and a second pump body connected to a waste liquid guide pipe is installed inside the waste liquid cylinder.

[0007] Furthermore, in the aforementioned easy-to-clean electric suction device, vertical slide rails are symmetrically installed on the upper side of the outer box, and sliders that slide and are limited in the vertical slide rails are symmetrically installed on the lower side of the horizontal support plate. A locking screw is installed on the slider to lock its position in the vertical slide rail. The vertical slide rails, sliders, and locking screws together constitute a height fine-tuning mechanism.

[0008] Furthermore, in the aforementioned easy-to-clean electric suction device, the bottom end of the waste liquid suction tube is provided with a gravity ball with a suction port.

[0009] Furthermore, in the aforementioned easy-to-clean electric suction device, the bottom end of the cleaning tube is fitted with a weight to improve its stability during spin.

[0010] Furthermore, in the aforementioned easy-to-clean electric suction device, the bottom end of the weight is equipped with a suction cup that facilitates locking its position.

[0011] Furthermore, in the aforementioned easy-to-clean electric suction device, the overflow prevention cap on the buffer bottle is connected to the suction device body via a first suction hose, and a second suction hose is connected between the overflow prevention caps on the buffer bottle and the collection container bottle.

[0012] Furthermore, in the above-mentioned easy-to-clean electric suction device, the cleaning method of the electric suction device includes the following steps: S1. Pre-cleaning stage: Before the formal cleaning, inject a small amount of disinfectant into the buffer bottle and collection container bottle through the disinfectant pump pipe to allow the disinfectant to initially rinse the inner wall of the bottle and remove most of the easily detachable residues. S2, Disinfectant Cleaning Stage: Start the first pump to deliver the disinfectant from the storage tank to the cleaning tube through the disinfectant pumping pipe, convex pipe, and liquid guiding slip ring. The disinfectant is then sprayed out by the nozzle to thoroughly clean the inside of the buffer bottle and collection container. At the same time, the cleaning tube rotates under the action of the baffle, so that the disinfectant covers the inside more evenly, ensuring that every corner is thoroughly cleaned. S3, Immersion stage: After the disinfectant is sprayed, keep the disinfectant in the bottle for 5 to 10 minutes to kill any possible microorganisms and further dissolve stubborn residues; S4. Waste liquid suction stage: After soaking, start the second pump to suction the waste liquid into the waste liquid cylinder through the waste liquid suction pipe and waste liquid guide pipe. Periodically transfer the waste liquid collected in the waste liquid cylinder for treatment through the drain pipe.

[0013] Furthermore, in the aforementioned easy-to-clean electric suction device, the disinfectant solution is formulated as follows (taking 1000ml as an example): 35ml of 30% hydrogen peroxide solution; 650ml of 95% ethanol; 8ml of cocamidopropyl betaine; 2g of sodium benzoate; and purified water added to 1000ml.

[0014] Furthermore, in the aforementioned easy-to-clean electric aspirator, the preparation steps of the disinfectant solution are as follows: 95% ethanol is filtered through a 0.22μm filter membrane for sterilization; hydrogen peroxide solution is pre-cooled to 10℃; each component is added in sequence, and the mixture is stirred at 200-350rpm for 15-20min.

[0015] The beneficial effects of this invention are: 1. Automatic cleaning function: It can automatically clean the buffer bottle and collection container bottle, which solves the problems of low efficiency and increased safety risks caused by the need for manual cleaning of existing electric suction devices.

[0016] 2. Spinning Cleaning Design: The outside of the cleaning tube is equipped with a baffle to enable spinning. During the cleaning process, the spinning allows the disinfectant sprayed from the nozzle to more evenly cover the inside of the buffer bottle and the collection container bottle, improving the cleaning effect.

[0017] 3. Height Adjustable: The height of the horizontal support plate can be finely adjusted by a height fine-tuning mechanism consisting of a vertical slide rail, a slider, and a locking screw, thereby adapting to different sizes of buffer bottles and collection container bottles and improving the versatility of the equipment.

[0018] 4. Convenient waste liquid treatment: Equipped with a waste liquid cylinder, the waste liquid after cleaning can be collected into the waste liquid cylinder through the waste liquid guide pipe and the waste liquid suction pipe, and discharged through the drain pipe, which facilitates the treatment of waste liquid.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0031] In this embodiment, the disinfectant solution is formulated for 1000ml as follows: 35ml of 30% hydrogen peroxide solution; 650ml of 95% ethanol; 8ml of cocamidopropyl betaine; 2g of sodium benzoate; and purified water added to 1000ml.

[0032] In this embodiment, the preparation steps of the disinfectant are as follows: 95% ethanol is filtered through a 0.22μm filter membrane for sterilization; hydrogen peroxide solution is pre-cooled to 10℃; each component is added in sequence, and the mixture is stirred at 200-350rpm for 15-20min.

[0033] In this embodiment, the disinfectant formula is reasonable and can effectively disinfect the buffer bottle and collection container bottle, kill any microorganisms that may be present, and further reduce the risk of infection.

[0034] The working principle of this embodiment is as follows: Overall structural layout: The suction device body 2 and the positioning seat 3 are installed on the upper side of the mobile cart 1. The buffer bottle 4 with an overflow cover 6, the collection container bottle 5, and the cleaning assembly 7 are snapped onto the upper side of the positioning seat 3.

A second suction hose is connected between the overflow covers on the buffer bottle 4 and the collection container bottle 5 to form a channel for suctioning liquid.

[0035] Cleaning component structure: The outer box 701 of the cleaning component 7 is equipped with two sets of disinfectant storage cylinders and waste liquid cylinders. The front side plate of the outer box 701 is provided with a replenishment pipe 702 and a drain pipe 703, which are used to replenish the disinfectant storage cylinders and drain the waste liquid from the waste liquid cylinders, respectively. The upper side panel of the outer box 701 is equipped with a waste liquid guide pipe 708 and a disinfectant pumping pipe 709. The waste liquid guide pipe 708 is embedded in the horizontal support plate 704 and connects to the waste liquid suction pipe 710.

Locking screws 707 are installed on the sliders 706. By adjusting the position of the locking screws 707 in the vertical slide rails 705, the height of the horizontal support plate 704 can be finely adjusted to ensure that the weight 715 can contact the bottom surface of the corresponding bottle inner cavity.

[0037] Cleaning Process: When cleaning is required for buffer bottle 4 and collection container bottle 5, the first pump is activated, and the disinfectant in the disinfectant storage cylinder is delivered to the cleaning pipe 714 through the disinfectant pumping pipe 709, the convex pipe 712, and the liquid guiding slip ring 713. The disinfectant is then sprayed out by the nozzle 716 to clean the inside of buffer bottle 4 and collection container bottle 5. Simultaneously, under the action of the baffle 717, the cleaning pipe 714 rotates, ensuring a more even distribution of the disinfectant inside. After cleaning, the second pump is activated, and the waste liquid is drawn into the waste liquid cylinder through the waste liquid suction pipe 710 and the waste liquid guide pipe 708. Finally, the waste liquid is discharged through the drain pipe 703.
