A liquid adding device for hydrogen peroxide low temperature sterilization equipment

Abstract

The invention discloses a liquid adding device for hydrogen peroxide low-temperature sterilization equipment, which includes an acupuncture system, a cassette with multiple capsules, a clamping part, a base, a positioning plate, a guide rail and a linear motor. There is a leakage hole on the top, the acupuncture system is connected to the screw of the linear motor, and the rotation of the screw of the linear motor drives the acupuncture system to move left and right along the guide rail for precise positioning. The card slot and the boss supporting the cassette, the clamping part is connected with the positioning plate through the linear sliding bearing, and is close together under the action of the spring. Under normal conditions, the cassette is clamped on the positioning plate and the clamping part to form a joint in the card slot. The invention can automatically store empty cassettes, and move the acupuncture system relative to the cassette during the liquid extraction process, which changes the installation of the cassette and the movement mode of liquid extraction, saves the space occupied by the equipment, and is conducive to the realization of the equipment. Miniaturization and compaction.

Description

technical field [0001] The invention relates to a liquid filling device for low-temperature sterilization equipment, in particular to a hydrogen peroxide solution filling system for low-temperature plasma sterilization equipment, and belongs to the technical field of medical device disinfection. Background technique [0002] In the medical field, the disinfection and sterilization of medical devices is particularly important. At present, the main sterilization methods are high-temperature sterilization and low-temperature sterilization. Sterilize medical devices that are not resistant to high temperatures, such as polymer materials and plastic materials. The most advantageous and popular low-temperature disinfection and sterilization method today is the use of hydrogen peroxide medium for disinfection and sterilization, among which hydrogen peroxide low-temperature plasma sterilization technology is the most widely used, and is widely used in biology, pharmaceuticals, medica...

Problems solved by technology

The working principle of its multi-capsule cassette injection is: insert the cassette into the liquid filling device from the window of the device along its long direction, and then push the cassette forward and backward by the cylinder, so that each capsule in the cassette is aligned with the needle one by one. The needle of the acupuncture system is used to extract the liquid, that is, the acupuncture system is fixed, and the cassette moves back and forth relative to the acupuncture system. Due to its structural limitations, the multi-capsule cassette injection system with this structure only It is suitable to be installed at a higher position. If it is installed at a lower position, it is inconvenient to operate and it is difficult to observe the actual state of the cassette during work. At the same time, the cassette moves back and forth and the acupuncture system does not move. Ensuring that the longer size cassette has sufficient displacement space in the length direction will inevitably increase the space occupied by the device in the length direction and increase the volume of the device. In addition, when the hydrogen peroxide solution in all capsules in the cassette After being taken out, manual participation is required to remove the empty cassette, and manual contact with the unsealed or used hydrogen peroxide cassette may pose a safety hazard to the operator due to the residual hydrogen peroxide solution

[0005] In the prior art, there is also a turntable liquid injection technology for the injection of hydrogen peroxide solution, as shown in Chinese patent 201110428927.1, but because the turntable liquid injection device needs to rotate, it takes up a lot of space, and there is also a need for manual participation. Insufficient removal of used hydrogen peroxide cartridges or clips
