Problems solved by technology

[0002] In the current situation, hospitals mainly use manual cleaning or spray machines to clean rigid endoscopes. Because some rigid endoscopes have small lumen apertures, it brings great difficulty to cleaning, especially when using spray machines. When cleaning, the perfusion tube inside is completely impassable, so in the process of decontamination, it is often found that the cleaning is not clean and backwashing. If it is completely manual cleaning, the labor intensity of medical staff will be very high, and infection incidents are prone to occur, because Most of the operations performed by rigid endoscopes are susceptible to infection, and are greatly affected by human factors, making it difficult to stabilize the cleaning quality
[0003] At present, hospitals mainly rely on manual scrubbing for the cleaning of rigid endoscopes. However, the lumen diameter of some rigid endoscopes is extremely small, which brings a lot of trouble to the cleaning staff, and it is difficult to guarantee the cleaning quality. If the cleaning is not thorough, it will bring the risk of infection to the follow-up surgeons, and the surgical operations performed by rigid endoscopes are generally relatively high-risk and susceptible to infection, so the problem of endoscope cleaning has always plagued major In hospitals, our multi-stage pulse cleaning technology has a good cleaning effect on rigid endoscopes and conventional instruments, and can effectively solve this problem

Embodiment 1

[0040] A multi-stage pressure-changing pulse cleaning system, which consists of a water supply valve 01 and connecting pipelines 10 at both ends, the inlet of the connecting pipeline is connected to an external water inlet, and the outlet is connected to a cleaning cabin; the cleaning cabin 12 consists of a cleaning tank and a tank cover Composition; M-type heating pipes 11 are evenly arranged at the bottom of the cleaning cabin 12; the detection hole of the digital display vacuum pressure gauge 13 is at the upper end of the cleaning cabin 12 and above the water level; the water inlet end of the drain pipe and the bottom of the cleaning cabin 12 The liquid outlet is connected, and the water outlet is connected with the external drain; the air-break valve 03 and the liquid-break valve 04 are connected to the filter 14 at the inlet end, and the air-break valve 03 is connected to the air-break hole 19 on the upper part of the cleaning cabin 12 , the gas outlet end of the liquid br...

Embodiment 2

[0042] A cleaning method for a multi-stage pressure-changing pulse cleaning system. For the cleaning of surgical instruments, we first put the parts to be cleaned into the cleaning cabin as required, close the cleaning cabin door, and replenish water to the cleaning cabin 12. After setting the water level, heat the cleaning liquid in the cleaning cabin, and set the temperature at 45°C to 55°C. After the temperature reaches the set temperature, turn on the vacuum valve 02 and the vacuum pump to vacuumize the cleaning cabin. During the process, the gas in the cleaning chamber is pumped out. With the gradual increase of the vacuum degree, the water in the tank gradually begins to roll and tremble. After the pressure sensor detects that the pressure reaches the set pressure and maintains it for a period of time, open the liquid The breaking valve 04X0 is closed after 0 seconds. Due to the huge pressure difference inside and outside, a large amount of air through the liquid breaking...

Embodiment 3

[0044] A cleaning method for a multi-stage pressure-changing pulse cleaning system. For the cleaning of lumen instruments, we first put the parts to be cleaned into the cleaning cabin as required, close the cleaning cabin door, and replenish water to the cleaning cabin 12. After reaching the set water level, heat the cleaning fluid in the cleaning cabin at a temperature of 45°C to 55°C. After the temperature reaches the set temperature, turn on the vacuum valve 02 and the vacuum pump to vacuumize the cleaning cabin. During the process, the air in the cleaning cabin is pumped out, and as the vacuum gradually increases, the water in the tank gradually begins to roll and tremble, and the air in the lumen device to be cleaned in the cleaning cabin is pumped out and gradually The hot steam generated in the tube cavity replaces it. After the pressure sensor detects that the pressure reaches the set pressure and maintains it for a period of time, close the vacuum valve 02, open the ai...

Abstract

The invention provides a multistage variable-pressure pulse washing system and a washing method thereof. The washing system mainly comprises a water charging system, a heating device, a washing cabin, a pressure detection device, a drainage system, a gas breaking system, a water level detection system and a vacuum pump circulation system. The washing method comprises the steps of putting an object to be washed into the washing cabin, closing a cabin door, and supplementing cleaning fluid; when the cleaning fluid reaches a set liquid level, starting to heat to be 45 DEG C to 55 DEG C; when the temperature reaches set temperature, starting a vacuum pump to pump out gas in the washing cabin; reducing the boiling point of the cleaning fluid in a tank along with the continuous reduction of the vacuum degree in the tank, starting to shaking and boiling the liquid in the tank when the liquid in the tank reaches the boiling point, after maintaining the state for a while, switching on a liquid breaking valve or a gas breaking valve for 1s to 30s, and quickly recovering the pressure in the washing tank; repeating the steps of vacuum pumping and switching on the liquid breaking valve or the gas breaking valve for washing; after the washing is finished, taking the washed object out. According to the multistage variable-pressure pulse washing system and the washing method thereof provided by the invention, the manpower is saved, the simplicity and the convenience in operation are realized, and the washing effect is good.
