Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a multi-interface small animal ventilation device. Background Technique

[0002] Mechanical ventilation (MV) plays an important role in the treatment of critically ill patients and the maintenance of anesthesia. However, improper use of MV itself can induce severe lung injury. Higher tidal volume (VT) during MV can damage the alveolar-capillary mucosal barrier, destroy the endothelial cells and epithelial cells of lung tissue, and increase its permeability. Therefore, animal experiments of external lung injury are usually required.

[0003] The existing small animal ventilation devices can only ventilate one small animal at a time, greatly reducing the use efficiency and working efficiency.

[0004] A Chinese patent discloses a multi-interface small animal ventilation device (publication number: CN 216136104 U). The patented technology can include a breathing circuit, a ventilator, and a plurality of breathing three-way connectors. The ventilator and all breathing three-way connectors are connected to the breathing circuit, and the breathing three-way connectors are connected end to end in sequence. The breathing three-way connector includes an air inlet end, an air outlet end, and a breathing end. The air inlet end and the air outlet end are connected to the breathing circuit, and the breathing end is docked with the small animal's breathing. However, the small animal closest to the ventilator in the center receives less breathing, and the breathing pressure received is much lower compared to the small animals on the left and right sides. Therefore, those skilled in the art provide a multi-interface small animal ventilation device to solve the problems raised in the above background technique. Summary of the Invention

[0005] The purpose of the utility model is to provide a multi-interface small animal ventilation device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A multi-interface small animal ventilation device includes an air pump, a transmission structure, and a ventilator structure. It is characterized in that a transmission structure is arranged at the upper end of the air pump, and a plurality of ventilator structures are arranged at the upper end of the transmission structure.

[0008] As a further scheme of the utility model: an air outlet pipe is arranged at the upper end of the air pump, and an air inlet pipe is arranged at the lower end of the air pump. Transmission pipes are arranged at the upper ends of the air outlet pipe and the air inlet pipe. A filter is arranged at the upper end of the upper transmission pipe, and a breathing mask is arranged at the upper end of the lower transmission pipe.

[0009] As a further solution of the utility model: A plurality of ventilators are arranged at the upper end of the transmission pipeline. Air inlets are arranged on the left side of each ventilator, and ventilators are arranged on the right side of each ventilator. Switch valves are arranged inside each ventilator. Telescopic transmission pipes are fixedly connected to the upper ends of the ventilators. A breathing mask is arranged on the other end surface of the telescopic transmission pipe. A sealing block is arranged at the connection between the breathing mask and the telescopic transmission pipe, and the breathing mask is movably connected to the telescopic transmission pipe.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: Firstly, by using different small animals and replacing the corresponding breathing masks, gas transmission is carried out through the air pump and the transmission pipeline. Open the switch valve arranged at the upper end of the ventilator to ventilate the small animals. Since the utility model is provided with a breathing mask, the breathing mask adopts a soft material and a humanized shape design, which reduces the discomfort of animals, improves the ventilation effect and guarantees the welfare of animals. Since a plurality of ventilators are provided, traditional small animal ventilation devices usually only provide a single type of interface, while the multi-interface device can provide a variety of interface options to adapt to different types and sizes of small animals. This can better meet the ventilation needs of various animals, increase the applicability and flexibility of the device, and the design positions between the ventilators are reasonable, so that small animals at any position can receive the same ventilation effect. Since a filter and a pressure sensor are provided, the device is internally provided with a filter to remove impurities and particles in the gas, ensuring the safety of the ventilation process. The device is equipped with a pressure sensor to monitor the ventilation pressure in real time, ensuring the safety of the ventilation process. Description of the Drawings
