Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compression pumps, in particular to a meterable compression pump device. Background Art
[0002] Flexible endoscopes are increasingly used as equipment for disease diagnosis and treatment in medical institutions, and higher requirements are being placed on the quality of endoscope disinfection. Multi-enzyme detergent is a commonly used cleaning solution for flexible endoscopes and is used in major medical institutions. Currently, the container for multi-enzyme detergent is a barreled device, and the dilution ratio of multi-enzyme detergent is 1:1000. Usually, 10,000 mL of water is required to clean a respiratory endoscope, which means 10 mL of multi-enzyme detergent is required, while 20,000 mL of water is required to clean a digestive endoscope, which means 20 mL of multi-enzyme detergent is required. During the cleaning process, endoscope disinfection personnel need to open the barrel lid, then use a 10 mL or 20 mL empty needle to extract the multi-enzyme detergent from the bottle mouth and inject it into the water. However, the inventors of this application found through on-site use research that using an empty needle for aspiration each time is costly and inconvenient. At the same time, opening the barrel lid for aspiration also increases the chance of contaminating the multi-enzyme solution. Without using empty needles for quantitative extraction, some decontamination personnel, for the sake of convenience, will estimate the required amount of multi-enzyme detergent and then pour it. However, this may result in insufficient amount, seriously affecting the quality of endoscope decontamination, or excessive amount, resulting in unnecessary waste. Therefore, it is urgent to change this situation. Utility Model Content
[0003] In view of the technical problems that the existing soft endoscope decontamination method uses an empty needle to aspirate the multi-enzyme cleaning agent each time, which is costly and inconvenient, and opening the barrel cover to aspirate also increases the chance of contaminating the multi-enzyme liquid. If pouring is used, there is a possibility that the amount taken is insufficient or excessive, the utility model provides a metered pressing pump device.
[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

On the other hand, each time the slider slides, the pump volume of the hollow cavity inside the pump body is compressed to a preset amount, which is 10mL or 20mL. That is, a measurable pressing pump device with a preset amount of 10mL or 20mL can be made respectively. When the pressing head is pressed to the bottom, the volume of the multi-enzyme liquid flowing out of the liquid outlet channel of the pressing head is 10mL or 20mL. Therefore, each time the pressing head is pressed to the bottom, 10mL or 20mL of the multi-enzyme liquid can be taken out. At the same time, the scale mark of the same amount as the preset amount is set on the wall of the liquid reservoir, and the amount of 10mL or 20mL of the multi-enzyme liquid flowing out can be confirmed and measured again, so that the required amount can be accurately taken out by pressing once, thereby meeting the amount required for cleaning of respiratory endoscopes and digestive endoscopes commonly used in clinical practice, and the measurement is accurate and efficient.
