Embodiment 1

[0031] The specific structures of the first N-way distributor and the second N-way distributor of this embodiment are as follows: image 3 shown. When N=4, the first N-way distributor and the second N-way distributor include a main path and four branch paths. As mentioned above, N=4 is only an example, and N can also be equal to 2, 6, 8, 10 and so on.

[0032] figure 2 The first four-way allocator and the second four-way allocator are generally realized by a simple one-way-multiplex branch structure. However, this traditional branch pipeline can only approximately distribute the gas flow evenly in the case of fewer branches. When multiple branches are connected to the main path at the same time, it is easy to generate eddy current and pipeline vibration, resulting in uneven flow distribution of the system.

Embodiment 2

[0044] Such as Figure 5 Shown is a schematic structural diagram of the first four-way distributor and the second four-way distributor in the second embodiment. Compared with Embodiment 1, the pipe diameters of the first branch path 12, the second branch path 13, the third branch path 14, and the fourth branch path 15 of the four-way distributor of this embodiment gradually increase along the length direction of the main path . Thereby, the pitch between the branch paths can be shortened. Preferably, the diameter ratio of each branch path of the four-way distributor in this embodiment is h 1 :h 2 :h 3 :h 4 =1:1.3:1.7:2. At this time, the distance G' between the shortened branch paths is only about half of the distance G in Embodiment 1, that is, G'=0.55G. As a result, a more compact four-way distributor can be obtained, and this advantage is more prominent when there are many branch paths.

[0045] Such as Image 6 Shown are schematic diagrams of various embodiments o...

Embodiment 3

[0051] Such as Figure 7 Shown is the third embodiment of the present invention. Compared with the first embodiment, in the third embodiment, an opening (not shown) is provided at the terminal end of the main path 11, and an adjusting screw 114 is sleeved in the opening to adjust An adjusting washer 113 is connected to the end of the screw 114 in the main path 11 away from the constant diameter section 111 . Rotating the adjusting screw 114 can adjust the position of the adjusting washer 113 in the main path 11 , so as to fine-tune the airflow resistance in the main path 11 and reduce the possibility of eddy current generation. Preferably, the outer diameter of the adjusting washer 113 is equal to the inner diameter of the end of the main path 11 away from the constant diameter section 111 . The material of the adjusting gasket 113 can be silicone to provide good airtightness.

Abstract

A ventilator adapter and a ventilator system. A ventilator adapter includes: a first N-way distributor (1), a second N-way distributor (2), and N Y-shaped adapters; the N-way distributor includes a main path (11) and an N-way branch path, The main path (11) comprises a main path constant diameter section (111) and a main path variable diameter section (112); the pipeline diameter of the main path variable diameter section (112) is along the length away from the main path constant diameter section (111) The direction decreases linearly. A ventilator adapter proposed by the present invention can be connected to a ventilator in the prior art so that multiple patients can share one ventilator, and each branch pipeline obtains a relatively average flow rate, which is conducive to expanding the capacity of a single ventilator. The number of patients supported, maximizing the efficiency of the ventilator.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a ventilator adapter and a ventilator system. Background technique [0002] As an effective means of artificially replacing the function of spontaneous ventilation, the ventilator has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. Such as figure 1 Shown is a schematic structural diagram of a ventilator system in the prior art. The ventilator system in the prior art includes a ventilator 1', a humidifier 2', a Y-shaped adapter 3', a pressure flow meter 4', a pressure sensor 5' and a first A pressure detection tube 51' and a second pressure detection tube 52'. [0003] The upper one connected to the ventilator 1' receives exhaled air from the patient through a first branch, as indicated by the first large arrow pointing towards the ventilator 1', ...
