Description

Technical Field

[0001] This invention relates to the field of medical and nursing device technology, specifically to a vomiting purification device and method for gastroenterology. Background Technology

[0002] Patients in the gastroenterology department often experience nausea and recurrent vomiting, which is commonly seen in conditions such as acute gastroenteritis, gastric ulcers, pancreatitis, gastrointestinal reactions after chemotherapy, and upper gastrointestinal bleeding. When bedridden patients, elderly patients, and critically ill patients in the emergency department vomit, there are problems such as high nursing difficulty, high risk of contamination, and high probability of cross-infection. Therefore, it is necessary to use a vomit purification device for gastroenterology to purify the vomit of patients.

[0003] Existing vomit purification devices mostly operate on a constant negative pressure output, which cannot adapt to the pulsatile and intermittent output characteristics of human vomiting. During the peak of a patient's vomiting, insufficient constant negative pressure suction can easily lead to vomit splashing and odor diffusion. During the intervals between vomiting, continuous constant negative pressure suction can easily cause negative pressure irritation to the patient's mouth and nose, causing throat discomfort, choking, and worsening nausea, seriously affecting the patient's comfort and recovery. Furthermore, traditional vomit purification devices have a single purification mode, only achieving simple waste collection and preliminary odor filtration. They cannot perform graded and targeted treatment of food residue, gastric juice, bacteria, and odorous gases in vomit, resulting in incomplete purification. Odors may remain in the ward, and the subsequent waste cleaning process may expose bacteria, increasing the risk of infection for medical staff.

[0004] Combining the above problems, we find that existing vomit purification devices for gastroenterology have difficulty simultaneously avoiding the aforementioned issues during use. Even if they can solve these problems, they require external tools, thus failing to achieve the desired effect. Therefore, we propose a vomit purification device and method for gastroenterology.

[0015] A purification method for a vomit purification device used in gastroenterology includes the following steps: S1: First, a multi-stage processing box fixed on a movable base plate is used. Inside the multi-stage processing box, there are liquid storage chambers, air purification chambers, and solid filtration chambers to facilitate separate purification of the patient's vomit. The solid filtration chamber is connected to the installation enclosure by a pull frame and the top plate using two sets of mounting bolts, making it easy to install the pull frame into the solid filtration chamber. Two sliding frames are set inside the pull frame to facilitate the filtration and collection of solid matter in the vomit through a filter screen vibrated by a vibration motor. Two low-temperature plasma sterilization devices are fixed inside the air purification chamber to sterilize the substances passing through the air purification chamber with low-temperature plasma. A sliding liquid container is set inside the liquid storage chamber to collect the liquid in the vomit. S2: Next, the connecting pipe on the top plate is used to facilitate the connecting ring of one end of the conveying telescopic pipe to be fitted onto the outside of the connecting pipe. The mounting nut on the outside of the conveying telescopic pipe is threaded into the threaded groove on the top plate, so that the conveying telescopic pipe can be installed above the top plate. The vomit collection hood at one end of the conveying telescopic pipe is used to facilitate the conveying of the patient's vomit into the multi-stage treatment box. By connecting a check valve on the outer surface of the conveying telescopic pipe, the backflow of vomit, odor and germs is completely eliminated from the physical level, effectively avoiding secondary pollution and secondary vomiting of the patient. A pressure and flow sensor is installed in the conveying telescopic pipe to detect the flow pressure and flow signal of vomit in real time. S3: The odor is then transported from the multi-stage treatment chamber to the air purification chamber for treatment by activated carbon adsorption plates. The gas is then transported to the negative pressure pump via a negative pressure pipe. The pressure and flow sensor is connected to the negative pressure pump signal through the PLC controller. This technology can overcome the limitations of traditional constant negative pressure and accurately adapt to the physiological pattern of human pulse vomiting. It solves the problems of overflow of waste and diffusion of odor during the peak of vomiting, and avoids the stimulation of the patient's throat by continuous negative pressure during the intermittent period. This greatly improves the patient's comfort and nursing safety, and meets the actual needs of clinical nursing in gastroenterology.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention, by incorporating a multi-stage purification mechanism, utilizes a multi-stage processing box fixed to a movable base plate. Within this box are a liquid storage chamber, an air purification chamber, and a solid filtration chamber, facilitating separate purification of the patient's vomit. A pull-out frame within the solid filtration chamber is connected to a mounting bracket via two sets of mounting bolts on the top plate, allowing for easy installation. Two sliding frames within the pull-out frame facilitate the filtration and collection of solid matter from the vomit through a vibrating filter screen. Furthermore, two low-temperature plasma sterilization devices are fixed within the air purification chamber to sterilize the vomit. The device uses low-temperature plasma sterilization to collect vomit. A sliding liquid container within the liquid storage chamber collects the liquid. A sealing ring connects the pull plate to the multi-stage treatment box, and two sets of sealing strips on one side of the sealing ring engage with a sealing groove on the side of the multi-stage treatment box to improve the sealing of the connection. Two sets of magnetic columns on one side of the pull plate magnetically attract two sets of magnetic blocks fixed on one side of the multi-stage treatment box, ensuring the liquid container is stably installed in the liquid storage chamber to collect vomit. This system effectively classifies and treats food residue, gastric juice, bacteria, and odorous gases in the vomit, thus improving the purification effect of this gastroenterology vomit purification device.

[0017] Secondly, this invention, by incorporating an adaptive purification mechanism, utilizes a connecting pipe on the upper plate to facilitate the fitting of a connecting ring at one end of the conveying telescopic pipe onto the outside of the connecting pipe. A threaded mounting nut on the outside of the conveying telescopic pipe connects to a threaded groove on the upper plate, allowing the conveying telescopic pipe to be installed above the upper plate. A vomit collection hood at one end of the conveying telescopic pipe facilitates the transport of the patient's vomit to the multi-stage treatment box. A check valve connected to the outer surface of the conveying telescopic pipe physically prevents the backflow of vomit, odors, and bacteria, effectively avoiding secondary contamination and secondary vomiting by the patient. A pressure and flow sensor is installed inside the conveying telescopic pipe to... This device monitors the flow pressure and volume of vomit in real time. Odors from the multi-stage treatment chamber are transported to an air purification chamber where activated carbon adsorption plates process them. A negative pressure pipe then delivers the gas to a negative pressure pump. Pressure and flow sensors connected to the negative pressure pump via a PLC controller overcome the limitations of traditional constant negative pressure technology. It precisely adapts to the physiological rhythm of pulsatile vomiting, solving the problems of vomit overflow and odor diffusion during peak vomiting periods while avoiding the irritation of the patient's throat caused by continuous negative pressure during intermittent periods. This significantly improves patient comfort and nursing safety, aligning with the actual needs of clinical nursing in gastroenterology and further enhancing the purification effect of this vomit purification device for gastroenterology.

Two limiting strips 209 are fixedly connected to the inner bottom wall of the liquid storage cavity 202. The two limiting strips 209 are slidably connected to the inside of the two limiting grooves 208 respectively. By using the two limiting strips 209 inside the limiting grooves 208, the pulling liquid holding tank 206 can be limited, thereby improving the pulling stability of the liquid holding tank 206.

[0026] Please see Figure 2 Each set of mounting bolts 218 has a buffer pad 219 on its outer surface.

When a patient in the gastroenterology department needs to use this vomit purification device to purify the patient's vomit, firstly, use two sets of movable legs 4 and casters 5 to form a movable structure under the movable base plate 1, thereby facilitating the movement of the vomit purification device to the required position. Utilize the multi-stage processing box 201 fixed on the movable base plate 1, and within the multi-stage processing box 201, open a liquid storage chamber 202, an air purification chamber 203, and a solid filter chamber 204 to facilitate separate purification of the patient's vomit.

By fixing a magnetic plate 207 on one side of the liquid holding box 206, it is attracted to the inner wall of the liquid storage cavity 202, thereby improving the stability of the liquid holding box 206 installed in the liquid storage cavity 202. This allows the liquid holding box 206 to be stably installed in the liquid storage cavity 202 to collect vomit. By using two limiting slide strips 209 inside the limiting slide grooves 208, the pulling liquid holding box 206 can be limited, thereby improving the pulling stability of the liquid holding box 206. This allows for the graded and targeted treatment of food residue, gastric juice, bacteria and odorous gases in the vomit.

The outer surface of the conveying telescopic pipe 305 is fixedly connected to a check valve 306. The check valve 306 is a valve that automatically opens and closes its valve disc based on the flow of the medium itself, used to prevent the medium from flowing back. The input end of the conveying telescopic pipe 305 is fixedly connected to a vomit collection hood 307. The outer surface of the multi-stage treatment box 201 is fixedly connected to an air purification box 308. The air purification box 308 is connected to the air purification chamber 203. The air purification box 308 has activated carbon adsorption plates arranged at equal intervals snapped into its interior. 311, a mounting plate 309 is fixedly connected to the left side of several activated carbon adsorption plates 311.

[0032] The specific implementation of this embodiment is as follows: In use, first connect the negative pressure pump 313 and the pressure and flow sensor to the power supply. When a patient in the gastroenterology department needs to use this vomit purification device to purify the patient's vomit, first use the connecting pipe 301 connected to the upper top plate 216 to facilitate the connecting ring 303 at one end of the conveying telescopic pipe 305 to be sleeved on the outside of the connecting pipe 301. Then, the mounting nut 304 threaded on the outside of the conveying telescopic pipe 305 is threadedly connected to the threaded groove 302 opened on the upper top plate 216, so that the conveying telescopic pipe 305 can be installed above the upper top plate 216. The vomit collection cover 307 at one end of the conveying telescopic pipe 305 is used to facilitate the conveying of the patient's vomit to the multi-stage processing box 201. By connecting a check valve 306 on the outer surface of the conveying telescopic pipe 305, the vomit is physically prevented from being discharged. To completely prevent the backflow of vomit, odors, and germs, effectively avoiding secondary pollution and re-vomiting of patients, a pressure and flow sensor is installed in the delivery telescopic pipe 305 to detect the flow pressure and flow signal of vomit in real time. The odor in the multi-stage treatment box 201 is transported to the air purification box 308 for treatment by the activated carbon adsorption plate 311. The gas is then transported to the negative pressure pump 313 through the negative pressure pipe 312. The pressure and flow sensor is connected to the negative pressure pump 313 through the PLC controller. This technology can overcome the limitations of traditional constant negative pressure technology and accurately adapt to the physiological pattern of human pulse vomiting. It not only solves the problems of vomit overflow and odor diffusion during the peak of vomiting, but also avoids the stimulation of the patient's throat by continuous negative pressure during the intermittent period, greatly improving patient comfort and nursing safety, and meeting the actual needs of clinical nursing in gastroenterology.

A magnetic plate 207 is fixed on one side of the liquid collection box 206 to attract the liquid into the liquid storage chamber 2. The inner wall of 02 improves the stability of the liquid holding tank 206 installed in the liquid storage cavity 202, allowing the liquid holding tank 206 to be stably installed in the liquid storage cavity 202 for vomit collection. Two limiting slide bars 209 are located inside the limiting slide grooves 208, which can limit the movement of the liquid holding tank 206, thereby improving the stability of the liquid holding tank 206. This allows for the graded and targeted treatment of food residue, gastric juice, bacteria, and odorous gases in the vomit. In use, first connect the negative pressure pump 313 and the pressure and flow sensor to the power supply. When a patient in the gastroenterology department needs to use this vomit purification device to purify their vomit, first use the connecting pipe 301 on the upper top plate 216...To facilitate the connection of the connecting ring 303 at one end of the conveying telescopic pipe 305 to the outside of the connecting pipe 301, and to connect the mounting nut 304 threaded onto the outside of the conveying telescopic pipe 305 to the threaded groove 302 on the upper top plate 216, the conveying telescopic pipe 305 can be installed above the upper top plate 216. The vomit collection hood 307 at one end of the conveying telescopic pipe 305 facilitates the transport of the patient's vomit to the multi-stage treatment box 201. A check valve 306 connected to the outer surface of the conveying telescopic pipe 305 completely prevents the backflow of vomit, odors, and bacteria, effectively avoiding secondary contamination and secondary vomiting by the patient. A pressure is set inside the conveying telescopic pipe 305. A flow sensor is used to detect the flow pressure and flow rate of vomit in real time. Odors from the multi-stage treatment chamber 201 are transported to the air purification chamber 308 for treatment by activated carbon adsorption plates 311. The gas is then transported to a negative pressure pump 313 via a negative pressure pipe 312. The pressure and flow sensor, connected to the negative pressure pump 313 via a PLC controller, overcomes the limitations of traditional constant negative pressure technology. This method precisely adapts to the physiological rhythm of pulsatile vomiting, solving the problems of overflow and odor diffusion during peak vomiting periods while avoiding the irritation to the patient's throat caused by continuous negative pressure during intermittent periods. This significantly improves patient comfort and nursing safety, meeting the actual needs of clinical nursing in gastroenterology.

[0034] A purification method for a vomit purification device used in gastroenterology includes the following steps: S1: First, a multi-stage treatment box 201 fixed on a movable base plate 1 is used. Within the multi-stage treatment box 201, a liquid storage chamber 202, an air purification chamber 203, and a solid filter chamber 204 are provided to facilitate separate purification of the patient's vomit. A pull-out bracket 220 within the solid filter chamber 204 is used, connected and fixed to the installation enclosure 217 via two sets of mounting bolts 218 using the top plate 216. This allows for easy installation of the pull-out bracket 220 into the solid filter chamber 204. Because... Two sliding frames 221 are installed inside the pull frame 220 to facilitate the filtration and collection of solid matter in vomit through the filter screen 222 vibrated by the vibration motor 223 inside the sliding frame 221. Two low-temperature plasma sterilization devices 205 are fixed inside the air purification chamber 203 to sterilize the substances passing through the air purification chamber 203 with low-temperature plasma. A sliding liquid container 206 is installed inside the liquid storage chamber 202 to collect the liquid in the vomit. S2: Next, the connecting pipe 301 on the upper top plate 216 is used to facilitate the connecting ring 303 at one end of the conveying telescopic pipe 305 to be sleeved on the outside of the connecting pipe 301. The mounting nut 304 on the outside of the conveying telescopic pipe 305 is threadedly connected to the threaded groove 302 on the upper top plate 216, so that the conveying telescopic pipe 305 can be installed above the upper top plate 216. The vomit collection cover 307 at one end of the conveying telescopic pipe 305 is used to facilitate the conveying of the patient's vomit into the multi-stage treatment box 201. By connecting a check valve 306 on the outer surface of the conveying telescopic pipe 305, the backflow of vomit, odor and germs is completely eliminated from the physical level, effectively avoiding secondary pollution and secondary vomiting of the patient. A pressure and flow sensing sensor is installed in the conveying telescopic pipe 305 to detect the flow pressure and flow signal of vomit in real time. S3: The odor is then transported from the multi-stage treatment box 201 to the air purification box 308 for treatment by the activated carbon adsorption plate 311. The gas is then transported to the negative pressure pump 313 via the negative pressure pipe 312. The pressure and flow sensor is connected to the negative pressure pump 313 via the PLC controller. This technology can overcome the limitations of traditional constant negative pressure and accurately adapt to the physiological pattern of human pulse vomiting. It solves the problems of overflow of waste and diffusion of odor during the peak of vomiting and avoids the stimulation of the patient's throat by continuous negative pressure during the intermittent period. This greatly improves the patient's comfort and nursing safety and meets the actual needs of clinical nursing in gastroenterology.
