Problems solved by technology

The drip rate of ordinary infusion sets is often variable and requires constant manual adjustment, which is quite inconvenient and causes a great burden to nursing care; while the automatic infusion speed regulator currently used in clinical practice basically uses an infusion pump composed of electronic instruments and program-controlled software. , it is expensive, bulky, heavy, complex to operate, easy to damage, inconvenient to shift, and it is not easy to be widely used in clinical practice, and it can only take care of a very small number of patients who are critically ill and require special care.

Embodiment Construction

[0017] refer to figure 1 , 2 , 3, 4. As can be seen in the figure, the inner cavity of the box body 1 is provided with a medial septum 1 a , which divides the inner cavity of the body into a liquid inlet chamber 2 and a liquid outlet chamber 3 .

[0018] The top surface of the liquid inlet chamber 2 is provided with a liquid inlet 2a, and the liquid inlet 2a communicates with a drop bottle (not shown in the figure) through a transfusion tube. A liquid outlet 3a is opened on the bottom surface of the liquid outlet chamber 3, and the liquid outlet 3a communicates with a needle (not shown in the figure) through an infusion tube. The top surfaces of the liquid inlet chamber 2 and the liquid outlet chamber 3 are respectively provided with exhaust holes 2b, 3b, and the exhaust holes 2b, 3b communicate with the atmosphere through a common exhaust pipe, and a plug 4 is arranged in the exhaust pipe. 4 is connected to the top surface of the main body 1 through the belt 4a, so as to a...

Abstract

This invention provides an infusion flux speed regulator. It includes box that bore is separated into liquor feeding and filtrate room by longitudinal partition. Perforation hole is set at bottom of the partition, hollow barrel with piston, piston bar and release spring is set on one lateral wall of liquor feeding room, speed control baffle with liquor through hole is connected to bottom of piston bar, the baffle can vertical slide to insert the perforation hole of the partition. Speed adjusting turn table with crescent slot and cooperate with the partition is set in filtrate room, adjusting knob is set out of the box. Liquor enter liquor room and hollow barrel, and hydrostatic pressure to piston bar is generated to make the bar synchronization move follow the dropper bottle, so speed control baffle is driven to automatic adjust flow area of perforation hole and the slot, so the liquor drop speed or flux can reach the needed request. This adjustor is automatic adjust through piston, its using is convenient, price is low, it can be used as one-off product and is convenient to generalization.

Description

technical field [0001] The invention relates to medical equipment technology, in particular to an infusion flow speed regulator. Background technique [0002] During the infusion, the infusion speed should be determined according to the age, weight, condition of the infused person, the concentration of the drug in the liquid, the strength of the drug's side effects, and the functional status and blood pressure of the heart, liver, kidney and other important organs. Speed ​​regulation is very important. The drip rate of ordinary infusion sets is often variable and requires constant manual adjustment, which is quite inconvenient and causes a great burden to nursing care; while the automatic infusion speed regulator currently used in clinical practice basically uses an infusion pump composed of electronic instruments and program-controlled software. , it is expensive, bulky, heavy, complex to operate, easy to damage, inconvenient to shift, it is not easy to be widely used in c...
