Embodiment Construction
[0031] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0032] Such as figure 1 , 2 As shown, the pump base 1 includes a rotating pump core 2 with rollers and its driving motor 3, etc., and the inner side of the pump cover 4 has an annular guide groove 5 for placing the pump tube 16 and a hole that can pass through the transmission shaft of the mechanical indication system 17 of the watch. , There are also two grooves 6 on the pump cover 4 for the pump tube 16 to pass into and out of the pump cover 4 and communicate with the annular guide groove 5 . There is a watch mechanical indication system 17 on the outside of the pump cover 4. The pump base 1 and the pump cover 4 are connected by a hinge 7. The positioning angle 8 protruding from the edge of the pump base 1 has a positioning function to ensure the po...

The invention relates to an end face peristaltic infusion pump and a control method thereof. The end face peristaltic infusion pump comprises a pump base, a pump cover and a locking member of an end face peristaltic pump, wherein a cylindrical pump core is arranged in a cylindrical inner cavity of the pump base, the pump core is provided with a motor and a variable-speed gear, and an annular guide slot for accommodating a pump tube and two grooves which allow the pump tube to penetrate into and come out of the pump cover and are connected with the annular guide slot are formed on the inner side of the pump cover; an annular positioning gasket is arranged in the annular guide slot; a position sensor is arranged on the pump cover; a mechanical indicating device is arranged on the outer side of the pump cover; a coupling member coupled with a main drive shaft of the mechanical indicating device is arranged at the position of one side, on which a roller is arranged, of the pump core; and an ant-sliding card is fixedly connected with the pump tube and positioned at the inlet of a channel of the pump cover. The end face peristaltic infusion pump has the advantages that: the exchange of the infusion tube is convenient, the squeezing points of the infusion tube are increased and reliability is improved; the pump tube is squeezed in a continuous multi-point mode, a liquid infusion process is smooth and control precision is high; the structure is simple, a rolling part is used for improving the mechanical efficiency, manufacturing cost is reduced, maintenance is convenient and efficiency is high; and software control is adopted, and the degree of automation is high.
Description
technical field [0001] The invention belongs to an infusion pump for infusion of medicinal liquid, in particular to an end face peristaltic infusion pump for infusion of medicinal liquid and a control method thereof. Background technique [0002] Infusion is the basic medical work at present. With the development of medical technology, the application of infusion is becoming more and more extensive. Every outpatient clinic of a hospital has more than a dozen or even dozens of seats dedicated to infusion. In the ward, infusion is an indispensable part of daily care. However, the gravity-type infusion method with manual adjustment relies on manual observation of the droplet velocity for accuracy and manual control operation for reliability, making it difficult to effectively control the accident rate. In addition, medical nutrient solution usually relies on manual injection, which is very inconvenient. For this reason, the infusion pump was invented abroad, which can automat...
