Description

[0001] FLOW REGULATOR FOR MEDICAL INFUSION SET [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow rate regulator for a fluid set, and more particularly, to a flow rate regulator for a fluid set that can be safely used by locking a flow rate control lever for controlling the flow rate of a fluid in a rotated state.

As shown in Fig. 1, an intravenous (IV) system for administering a sap into a vein is composed of an infusion bottle 1 containing a sap and a syringe which is inserted into a sealing cap of the infusion bottle 1, And a drip chamber 12 which is fixed to the lower end of the insertion needle 11 and allows the liquid to drop in the form of a drop 12a (unit: gtt) A tube 13 connected to the drip chamber 12 and the injection needle 14 to serve as an infusion passage for the infusion fluid and a tube 13 mounted in the middle of the tube 13 And a fluid flow regulator 15 for controlling the flow rate of the fluid.

Generally, the insertion needle 11, the drip chamber 12, the tube 13, the injection needle 14 and the liquid flow rate regulator 15 are made into one set, .

When the liquid set 10 is connected to the liquid infusion bottle 1 and the liquid is injected continuously to the same patient, only the spent liquid bottle 1 is replaced.

The drip 12a falling from the inside of the drip chamber 12 is manufactured by forming the insertion needle 11 and the drip chamber 12 such that the liquid drop drops in a water droplet form and has a constant volume. For example, If you make 20 dots, one dots volume will be 1/20 cc. If you make 60 dots per 1 cc solution, one dots volume will be 1/60 cc.

Therefore, the flow rate of the liquid to be injected through the liquid set 10 can be calculated by measuring the period in which the drop in the drip chamber 12 drops.

When the fluid is injected into the patient, the infusion rate is prescribed according to the type of the fluid, the type of medicament mixed with the fluid, the condition of the patient, the type of the ill afflicted, and the fluid flow rate controller 15, .

In this case, if the flow rate of the injected fluid can not be adjusted to the prescribed flow rate, it is a cause of medical accident. Therefore, it is very important to control the flow rate of the fluid, and the fluid flow rate controller 15 controls the cross- So that the injection flow rate of the liquid can be adjusted by operating the operating portion 15a.

The fluid flow controller 15 shown in FIG. 1 is a so-called Roller Clamp, and includes a control unit 15a as a roller type. The manipulating portion 15a for pressing the tube 13 after passing through the tube 13 in the upper and lower groove 15b can be guided to the groove groove 15c and moved up and down.

Since the depth of the groove 15b is shallower toward the bottom and the tube 15 is pressed further as the operating portion 15a is moved downward, the flow rate is measured for each moving position while moving the operating portion 15a, The injection flow rate of the import is adjusted in such a manner as to stop the movement of the roller 15a.

However, since the roller clamp type liquid flow rate regulator 15 shown in FIG. 1 has to measure the flow rate while observing the drip chamber 12 every time the roller type operating portion 15a is moved each time, the troublesome measurement operation is repeated And the accuracy of the flow control was also reduced.

FIG. 2 is a view showing an IV flow regulator type among the kinds of the fluid flow regulator 15. The IV flow regulator type fluid flow regulator 15 has a dial The flow rate of the operating portion 15a which can be turned as if the flow rate of the fluid is adjusted to the graduation 15d indicated by the numerical value 15e displayed on the body 15f.

This is because when the manipulation part 15a is aligned with the graduation 15d of the numerical value 15e on which the fluid flow value to be injected is engraved, a structure for adjusting the cross-sectional area of the fluid passage (not shown) so that the fluid is injected at a flow rate corresponding to the numerical value 15e It is equipped.

The numerical value 15e engraved here is a value obtained by measuring the flow rate of the fluid after the fluid bottle 1 is set at the reference height designated at the time of manufacturing the fluid flow controller and the fluid set 10 is set, The flow rate can be easily adjusted by fitting the bottle (1) to the reference height and adjusting the value (15e).

However, the flow rate of the liquid injected into the intravenous injection system is not determined solely by the installation height of the liquid bottle (1), but the viscosity of the liquid depending on the type of liquid, the thickness of the injection needle (14), the patient's venous pressure, , The quality of the tube, the ambient temperature, the atmospheric pressure, and the like. Therefore, in actual use, it is indicated by the numerical value 15e engraved in the IV flow regulator type IV flow regulator 15 described above There is a large difference between the flow rate and the actually measured flow rate in a state in which the operation portion 15a is matched to the numerical value 15e.

Accordingly, even after the operating portion 15e is operated in accordance with the engraved numerical value 15e, the flow measuring process has to be repeatedly adjusted as in the case of the roller clamp type fluid flow regulator.

The problem here is that if the operator adjusting the fluid flow rate according to the prescribed order after installing the fluid set is reliable in the flow regulation performance of the flow regulator (IV Flow Regulator), it can be misjudged that it is set to the prescribed flow rate, It can lead to medical accidents.

On the other hand, even if the person in charge has measured the flow rate at the confirmation level after confirming that the flow rate is not in accordance with the prescribed flow rate after operating the operation portion with the numerical value 15e corresponding to the prescribed flow rate, There is a concern that the flow rate is repeatedly measured and adjusted to a certain point at the measurement point or to one point inferred from the repeated measurement point.

In this case, the inaccuracy of the flow measurement is also a problem in the repeated flow measurement process. Moreover, since such inaccurate flow control can be mistaken when the fluid in the fluid bottle is exhausted, There is a problem in that it can not be removed or the exhausted bottle can not be replaced, leading to medical accidents.

In addition, the conventional fluid flow controller can be rotated clockwise or counterclockwise 360 degrees when operating the operating part, so that the operating part is placed in an open numerical position in a priming state and the priming is completed by opening the tube The operating portion is rotated to adjust the flow rate, and the operating portion is freely rotated from the body to return to the open position again, or to deviate from the set value, thereby deteriorating the quality and safety of the product.
