Embodiment 1

[0033] like Figure 1~2 Among them, a dismantled combined squeeze pump includes a casing 3, and a groove body 1 is provided on the casing 3. The groove body 1 is provided with side walls and a bottom wall along the length direction. The end and the top are open, and the tank body 1 is used to place the pipeline 11;

[0034] One side wall of the tank body 1 is provided with a telescopic head 2 that moves along the width direction of the tank body 1 . With this structure, the pipeline 11 can be squeezed intermittently, thereby facilitating the delivery of the liquid through the deformation of the pipeline.

[0035] The preferred solution is Figure 1~2 , the telescopic head 2 extends along the axial direction of the pipeline 11 to expand the length of the extrusion pipeline 11 . This structure increases the amount of liquid delivered per squeeze.

[0036] The preferred solution is figure 1 Among them, the side wall opposite to the telescopic head 2 is provided with an arc-s...

Embodiment 2

[0051] like figure 2 Among them, a liquid supply system using the above-mentioned easy-to-disassemble combined squeeze pump includes a liquid container 14, the liquid container 14 is communicated with the pipeline 11, and the pipeline 11 is provided with a first one-way valve 12 and a second one-way valve 12. One-way valve 13, the liquid flow direction of the first one-way valve 12 and the second one-way valve 13 is 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 telescopic head 2 . With this structure, when in use, connect the pipeline 11 with the first check valve 12 and the second check valve 13 to the liquid container 14, and then connect the first check valve 12 and the second check valve 13 between the first check valve 12 and the second check valve 13. The pipeline between the two is clamped into the tank body 1, the switch 9 is activ...

Abstract

The invention provides a convenient and dismantling combined squeeze pump and a liquid supply system, comprising a casing, a groove body is arranged on the casing, the groove body is provided with a side wall and a bottom wall along the length direction, and two sides of the groove body are provided. The end and the top are open, and the tank body is used to place the pipeline; one side wall of the tank body is provided with a telescopic head that moves along the width direction of the tank body. pressure line. A liquid supply system using the above-mentioned easy-to-disassemble combined squeeze pump, a first one-way valve and a second one-way valve are arranged 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 valve is used to be arranged in the tank body, and can be squeezed and deformed by the telescopic head. Through the above solution, the telescopic head squeezes the pipeline to realize the delivery of the liquid, and the pipeline is easy to disassemble, and the pipeline is separated from the mechanical components, so that pollution will not occur.

Description

technical field [0001] The invention relates to the field of medical pumps, in particular to a removable combined squeeze 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. Its structure is shown in Chinese patent CN209671175U "a medical peristaltic pump head". By setting several 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 immediately stops flowing out when the motor stops rotating. . The 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 the disassembly is inconvenient. In the existing diaphragm pump, the liquid cannot be separated from the mech...
