Embodiment 1

[0033] Such as Figure 1~2 Among them, a detachable combined squeeze pump includes a housing 3, and a tank 1 is provided on the housing 3. The tank 1 is provided with a side wall and a bottom wall along the length direction, and the two sides of the tank 1 are The end and the top are open, and the tank body 1 is used to place the pipeline 11;

[0034] On one side wall of the tank body 1 is provided a telescopic head 2 that moves along the width direction of the tank body 1 , and the telescopic head 2 is connected with a driving device to drive the telescopic head 2 to radially squeeze the pipeline 11 along the pipeline 11 . With this structure, the pipeline 11 can be squeezed intermittently, so that the liquid can be transported through the deformation of the pipeline.

[0035] The preferred solution is as Figure 1~2 Among them, the telescopic head 2 extends along the axial direction of the pipeline 11 to expand the length of the extruded pipeline 11 . This is structured t...

Embodiment 2

[0051] Such as figure 2 Among them, a liquid supply system using the above-mentioned detachable combined squeeze pump, it includes a liquid container 14, the liquid container 14 communicates with the pipeline 11, and the pipeline 11 is provided with a first one-way valve 12 and a second one-way valve. One-way valve 13, the liquid flow direction of the first one-way valve 12 and the second one-way valve 13 are the same;

[0052] The pipeline 11 between the first one-way valve 12 and the second one-way valve 13 is used to be arranged in the tank body 1 and can be squeezed and deformed by the telescoping head 2 . With this structure, when in use, the pipeline 11 with the first one-way valve 12 and the second one-way valve 13 is connected with the liquid container 14, and then the first one-way valve 12 and the second one-way valve 13 are connected to each other. The pipeline between them is snapped into the tank body 1, the switch 9 is activated, and the telescopic head 2 recip...

Abstract

The invention provides a convenient-to-disassemble combined extrusion pump and a liquid supply system. The convenient-to-disassemble combined extrusion pump comprises a shell. A tank body is formed inthe shell. The tank body is provided with side walls and a bottom wall in the length direction. The two ends and the top of the tank body are open, and the tank body is used for containing a pipeline. A telescopic head moving in the width direction of the tank body is arranged on the side wall of one side of the tank body and connected with a driving device so as to be driven to extrude the pipeline in the radial direction of the pipeline. According to the liquid supply system adopting the convenient-to-disassemble combined extrusion pump, a first one-way valve and a second one-way valve arearranged on the pipeline, and the liquid flow directions of the first one-way valve and the second one-way valve are the same. The pipeline between the first one-way valve and the second one-way valveis used for being arranged in the tank body and can be extruded by the telescopic head to deform. By means of the scheme, the telescopic head extrudes the pipeline to achieve liquid conveying, the pipeline is convenient to disassemble, the pipeline is separated from mechanical elements, and pollution cannot occur.

Description

technical field [0001] The invention relates to the field of medical pumps, in particular to a detachable combined extrusion pump and a liquid supply system. Background technique [0002] At present, most medical pumps on the market are diaphragm pumps or peristaltic pumps, which are used to transport liquids. The tubing of the peristaltic pump is not easy to disassemble. For its structure, refer to the Chinese patent CN209671175U "a medical peristaltic pump head". By setting a number of rollers evenly distributed in the circumferential direction on the main shaft, and setting concave holes and pressure relief mechanisms on the cylindrical surface, the liquid stops flowing out immediately when the motor stops. . This technical solution can solve the problem of liquid pollution, but the pipeline of the peristaltic pump is difficult to separate from the power system, and it is inconvenient to disassemble. In the existing diaphragm pump, it is impossible to separate the liqu...
