specific Embodiment approach 2

[0030] On the basis of the specific implementation of the specific embodiment one, just as the accompanying drawings of the description figure 2 Shown, just: its weight meter 6 is a platform weighing shape structure, and the upper shelf of support body 1 places weight meter 6, places liquid bottle 2 on weight meter 6; Obtained the good effect of anticipation equally.

specific Embodiment approach 3

[0031] Carry out specific implementation on the specific implementation basis of specific embodiment one, a kind of using method of high-precision infusion pump, according to the following operation steps:

[0032] (1), apply the high-precision infusion pump described in Embodiment 1;

[0033] (2), according to the doctor's order, input the infusion amount and the infusion time into the single-chip microcomputer 301 of the infusion pump 3;

[0034] (3), the liquid bottle 2 that liquid medicine is housed is hooked on the weighing device 6;

[0035] (4), the liquid bottle 2 is connected with the infusion pump 3 by the flexible pipe 4;

[0036] (5), start the infusion pump 3 until the medicinal liquid flows out from the end of the infusion tube 5, then close the infusion pump 3;

[0037] (6), the needle on the end of the infusion tube 5 is inserted into the patient's venous blood vessel, and the infusion pump 3 is started again to perform infusion to the patient.

[0038] Thro...

specific Embodiment approach 4

[0039] Carry out concrete implementation on the specific implementation basis of specific embodiment two, three, namely: apply the high-precision infusion pump described in specific embodiment two, press the operation described in the using method of high-precision infusion pump described in specific embodiment three steps to implement. Also received the expected good results.

[0040] The embodiments provided by the present invention are only representative of the present invention and not all; as: the single-chip microcomputer 301, soft Pipe 4, infusion tube 5 all are existing known technology, just set up well-known weight meter 6, and the electrical connection of the weight signal output end of weight meter 6 and single-chip microcomputer 301; The technology provided can not only be applied in the specific implementation mode provided by the present invention, but also can be retrofitted and improved on other forms of infusion pumps, whether it is the "high-precision infu...

Abstract

The invention relates to a high-precision infusion pump and a using method thereof, belonging to the field of medical devices. The key is to always maintain accurate speed by carrying out the immediate implementation and the adjustment by a single-chip microcomputer according to a weight signal; the pump is characterized in that: the single-chip microcomputer is arranged in the infusion pump, an upper transverse frame of a frame body is hung with a weight meter, the weight meter is hung with a liquid bottle, the infusion pump is arranged on a lower transverse frame of the frame body, the liquid bottle is inserted with one end of a soft tube, the other end of the soft tube is inserted with an input end of the infusion pump, an output end of the infusion pump is inserted with an infusion tube, and the output end of the weight signal of the weight meter is electrically connected with the single-chip microcomputer. The operation steps of the method are as follows: the infusion amount and the infusion time are input to the single-chip microcomputer according to the order of doctor by the high-precision infusion pump, the liquid bottle is hung on the weight meter, the soft tube is use for connecting the liquid bottle with the infusion pump, the infusion pump is started to allow liquid medicine to be flowed out of the infusion tube, then the infusion pump is closed, and the infusion pump is started to carry out the infusion after a needle of the infusion tube is punctured into a vein of a patient. The high-precision infusion pump is used for infusion of the patient. The operation is simple, and the self-weight of liquid is a control signal for carrying out the immediate implementation and adjustment and maintaining the infusion speed.

Description

Technical field: [0001] The high-precision infusion pump and its use method of the present invention relate to the technical field of medical devices; in particular, it relates to the technical field of an instrument for medical infusion and its use method; in particular, it relates to the high-precision infusion pump and its use method technical field. Background technique: [0002] Due to the objective needs of the patient's specific condition, it is required that in the course of treatment, the amount of intravenous infusion and the speed of infusion per unit time have certain requirements, otherwise it may affect the therapeutic effect and even endanger the patient's life, so it is used for measurement. And instruments for controlling the amount and speed of infusion per unit time have emerged at the historic moment. What are commonly used in hospitals are medical devices called "infusion pumps". When using the existing "infusion pump" to infuse the patient, it is necess...
