Description

Technical Field

[0001] This utility model mainly relates to the field of medical equipment technology, specifically an integrated medical vacuum negative pressure machine. Background Technology

[0002] Medical vacuum negative pressure machines are widely used in hospitals for centralized negative pressure suction, generating suction at the end of operating rooms, emergency rooms, treatment rooms, and various wards for medical use.

[0003] Currently, conventional medical vacuum negative pressure systems mostly use conventional vacuum pumps. To ensure the negative pressure requirements of the entire hospital, these devices are large in size, have low integration, are inconvenient to install, and have low reliability in long-term stable operation. Water ring vacuum pumps have the advantages of strong negative pressure and stable structure, but they require a working fluid. Using traditional working fluid replenishment structures results in continuous water flow, leading to water waste and large wastewater discharge. Utility Model Content

[0004] To address the shortcomings of current technology, this utility model combines existing technology and, based on practical applications, provides an integrated medical vacuum negative pressure machine, which has advantages such as high equipment integration, stable and reliable operation, and low wastewater discharge.

[0005] The technical solution of this utility model is as follows:

[0006] An integrated medical vacuum negative pressure machine includes a frame, a vacuum pump mounted on the frame, and a vacuum storage tank. The frame is also equipped with a gas-water separator and a negative pressure exhaust sterilizer.

[0007] The vacuum pump is a water ring vacuum pump. The exhaust port of the vacuum pump is connected to the air inlet channel of the gas-water separator through a pipeline. The water inlet of the vacuum pump is connected to the water outlet of the gas-water separator. The exhaust channel of the gas-water separator is connected to the negative pressure exhaust sterilizer through a pipeline.

[0008] The air inlet of the vacuum pump is connected to the vacuum storage tank via a pipeline, and a sterilization filter is installed on the connected pipeline.

[0009] Furthermore, the gas-water separator includes a tank, and the air inlet channel and the exhaust channel are both located on the top of the tank.

[0010] Furthermore, an elbow is provided at the bottom of the air intake channel, so that the outlet of the air intake channel faces the inner wall of the tank.

[0011] Furthermore, the tank is also equipped with a liquid inlet, a temperature detection port, a liquid level display tube, an overflow port, and a drain port.

[0012] Furthermore, the cavitation port of the vacuum pump is connected to the gas-water separator via a PU tube.

[0013] Furthermore, there are two vacuum pumps arranged side by side. The exhaust ports of the two vacuum pumps are respectively connected to the corresponding air inlet channels of the gas-water separator. The air inlets of the two vacuum pumps converge and are then connected to the sterilization filter assembly.

[0014] Furthermore, both vacuum pumps are equipped with electromagnetic vacuum charging valves and check valves at the front end of their inlets.

[0015] Furthermore, the sterilization filtration assembly includes a biofilter and valves, with the valves installed at both the inlet and outlet of the biofilter.

[0016] Furthermore, the sterilization filter assembly is provided in two sets, and the two sets of sterilization filter assemblies are arranged in parallel.

[0017] Furthermore, the vacuum pump, vacuum storage tank, gas-liquid separator, and negative pressure exhaust sterilizer are respectively arranged at the four corners of the frame, with the vacuum pump and vacuum storage tank arranged diagonally, and the gas-liquid separator and negative pressure exhaust sterilizer arranged diagonally.

[0018] The beneficial effects of this utility model are:

[0019] 1. The vacuum negative pressure equipment provided by this utility model has a high degree of integration. The structure of using a water ring vacuum pump and a gas-water separator enables the equipment to operate efficiently and stably. It can also avoid the long water flow phenomenon common in similar products, thereby eliminating unnecessary water waste, reducing wastewater discharge, and lowering operating costs.

[0020] 2. The vacuum negative pressure machine provided by this utility model first passes through a biological filter and then through a negative pressure exhaust sterilization device before being discharged during the suction process, resulting in good environmental protection effect.

[0021] 3. The vacuum negative pressure machine provided by this utility model has two sets of vacuum pumps, one for backup and one for use, and they can automatically switch to the other when one fails. Two sets of sterilization filter components are also provided, which are for backup. When one set needs to replace the filter element, the equipment does not need to be stopped. Just close the valves before and after the set that needs to be replaced and start the other set to achieve the function.

[0022] 4. The vacuum negative pressure machine provided by this utility model adopts a unique gas-water separator structure, which can protect the water ring vacuum pump. The gas-water separator inlet pipe adopts the form of an elbow, so that the water flow will not be agitated by the air flow during the intake, which will cause water to be carried out during the exhaust. It can play the role of gas-water separation, and the water carried by the intake can also remain in the gas-water separator. Attached Figure Description

[0030] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0031] This embodiment provides an integrated medical vacuum negative pressure machine, the main structure of which is referenced. Figures 1-3 As shown.

[0032] The vacuum negative pressure machine mainly includes a frame 1, with a vacuum pump 2, a vacuum storage tank 5, an air-water separator 4, and a negative pressure exhaust sterilizer 3 fixedly installed at the four corners of the frame 1.

[0033] The vacuum pump 2 adopts a water ring vacuum pump structure, with two pumps arranged side by side. Each vacuum pump 2 is fixed to the frame 1 via rubber blocks. The exhaust port of the vacuum pump 2 is connected to the inlet channel 42 of the gas-water separator 4 through a piping system. The exhaust channel 41 of the gas-water separator 4 is connected to the negative pressure exhaust sterilizer 3, and the exhaust gas is discharged after sterilization. The cavitation port of the vacuum pump 2 is connected to the gas-water separator 4 through a PU pipe 9, thereby protecting the vacuum pump 2, preventing cavitation, and extending the service life of the vacuum pump.

[0034] The vacuum storage tank 5 is equipped with a negative pressure vacuum gauge, a pressure transmitter, and a bottom vent valve. The inlet of the vacuum pump 2 is connected to the vacuum storage tank 5 via a piping system. This piping system passes through a sterilization filter assembly 6, which mainly consists of a valve 62 and a biological filter 61. Two sets are arranged in parallel, serving as backups for each other. When one set needs filter replacement, the equipment does not need to be stopped; simply close the valves before and after the set requiring replacement and start the other set to resume operation. This piping system is divided into two parallel pipelines, which are then connected to the corresponding vacuum pumps 2 via two branch pipelines. An electromagnetic vacuum valve 8 and a check valve 7 are installed on the pipelines connecting to the vacuum pumps 2 to effectively ensure that the equipment reaches the required vacuum value and prevent backflow.

[0035] refer to Figure 4 , Figure 5 as well as Figure 6 As shown, this embodiment also provides a specific structure for a gas-water separator 4 used in the aforementioned vacuum negative pressure machine. This gas-water separator 4 is mainly used in medical vacuum negative pressure machines, serving as a water storage unit for the vacuum pump 2 and for discharging exhaust gas.

[0036] The air-water separator 4 mainly includes a tank 43. Two air inlet channels 42 and one exhaust channel 41 are provided on the top of the tank 43. The air inlet channels 42 are used to connect to the vacuum pump 2, and the exhaust channel 41 is used to connect to the negative pressure exhaust sterilizer 3. Meanwhile, an elbow 44 is provided at the bottom of the air inlet channel 42, so that the outlet of the air inlet channel 42 faces towards the inner wall of the tank 43. This structure prevents water flow from being stirred up during air intake, thus avoiding water being carried out during exhaust, achieving air-water separation. Simultaneously, water carried by the intake air can remain in the air-water separator 4.

[0037] Multiple openings are designed on the tank 43 for automatic control operation in conjunction with a medical vacuum negative pressure machine. A solenoid valve is installed at the liquid inlet 48 to enable automatic liquid intake in conjunction with the control system. A temperature sensor is installed at the temperature detection port 47 to monitor the internal water temperature in real time. The control system automatically replenishes the water when the temperature is too high, lowering the internal water temperature through mixing to meet the operating requirements of the vacuum pump 2. A float level gauge is installed at the level gauge mounting port 46 to detect the water level inside the device. When the level is low, the control program automatically replenishes the water; when the level is high, replenishment stops, protecting the pump. The level display tube 49 is equipped with two shut-off valves for easy replacement in case of damage, and also displays the liquid level for easy observation by operators. The water outlet 410 connects to the vacuum pump 2, enabling real-time water intake and ensuring normal operation of the vacuum pump 2. The drain port 411 facilitates the discharge of internal waste liquid during subsequent cleaning of the device. The overflow port 45 prevents the internal liquid level from becoming too high and affecting the equipment's venting when the liquid inlet control fails. Meanwhile, the tank 43 is equipped with four fixed feet, ensuring stable fixation to the frame 1 of the medical vacuum negative pressure machine.
