Abstract

The invention provides a flow regulator for transfusion, which is a flow regulator used for a transfusion device. The flow regulator consists of a scale groove, a leather strip, an inclination groove and a roller, wherein the scale groove is transparent and provided with scale lines and corresponding flow readings, the leather strip is placed on the bottom part in the scale groove, and the inside of the leather strip is provided with the inclination groove which is inclined and is high at one end and low at the other end; the middle of one side of the roller is provided with a marker; and when the marker aligns the scale lines, the flow readings on the scale lines are the flow rate of the liquid medicine in the transfusion leather strip. The flow regulator has the advantages of high accuracy and quantization, and can replace the prior flow regulator for transfusion to be applied to the field of clinical transfusion.

Description

A kind of infusion flow adjuster

Technical field

The present invention relates to the flow regulator used on a kind of transfusion device, is scale to be arranged on a kind of specifically, can make the quantized infusion flow adjuster of infusion flow.

Background technology

Flow regulator on the transfusion device is made up of leather strap groove, roller at present, and the leather strap groove is gradient, and roller is placed in the leather strap groove, there is the transfusion leather strap roller below, the sliding roller, and roller is because the effect of leather strap slot slope, extruding transfusion leather strap, change transfusion leather strap inner chamber size, play a part to regulate infusion flow, because the leather strap groove is opaque, on do not have scale, it can only lean on the medicine number in several droppers to carry out, and can not quantize poor accuracy like this.

Summary of the invention

Purpose of the present invention is exactly in order to solve the shortcoming that above-mentioned infusion flow adjuster exists, and provides a kind of accuracy good, can make the quantized infusion flow adjuster of infusion flow.

For reaching this purpose, the present invention adopts following technical scheme:

The present invention is by the scale groove, leather strap, the gradient groove, roller is formed, the scale groove is transparent, one side has scale and corresponding flow reading, scale groove size shape is the leather strap groove of infusion flow adjuster roughly the same at present, but scale groove groove inner bottom part is circular-arc, scale groove groove inner bottom part is placed with leather strap, gradient groove in the leather strap, the gradient trench bottom is circular-arc, match with the leather strap inner chamber, gradient groove one end height, the other end is low, gradient in the gradient groove, there is roller the leather strap top, roller on the roughly the same present infusion flow adjuster of roller size shape, the underlined thing of centre one side of roller, roller can be along sliding before and after the scale groove, in the sliding process, roller extruding leather strap promptly is close to above the gradient groove by the top leather strap of roller crimping section, the leather strap inner chamber of the groove outside of this part that is squeezed all is blocked and clogs, medicinal liquid in this part leather strap can only flow through in groove, because leather strap inner liquid medicine flow velocity and the groove inner chamber relation of being in proportion, when roller sliding during to the high end of gradient groove, this end slot inner chamber is big, the leather strap inner liquid medicine by the time, the medicinal liquid flow velocity is also big, when roller sliding during to the lower of groove, the inner chamber of this end slot is little, the leather strap inner liquid medicine by the time, the medicinal liquid flow velocity is also little, wheel rolls before and after the scale groove everywhere the position all to a corresponding infusion flow should be arranged, when roller is fixed, when the graduation mark of a certain flow reading alignd on the label on the roller and the scale groove, at this moment, this scale reading was the infusion flow of leather strap inner liquid medicine, this flow reading accuracy height quantizes.

Compare with present infusion flow adjuster, it has increased a label on roller, change the leather strap groove into a graduated transparent body, and leather strap groove inner bottom part becomes circular-arc, and in leather strap, increased a gradient groove, make it transfusion and regulate quantification, accuracy height.

The specific embodiment

The present invention is by scale groove 1, leather strap 2, gradient groove 3, roller 4 is formed, scale groove 1 is transparent, on scale and corresponding flow reading are arranged, leather strap groove on the roughly the same present infusion flow adjuster of scale groove 1 size shape, scale groove 1 groove inner bottom part is circular-arc, scale groove 1 groove inner bottom part is placed with leather strap 2, leather strap 2 is the transfusion device leather strap, is placed with gradient groove 3 in the leather strap 2, and gradient groove 3 bottoms are circular-arc, supporting with leather strap 2 inner chambers, gradient groove 3 one end height, the other end is low, and is gradient in gradient groove 3 grooves, the width of groove is little, there is roller 4 leather strap 2 tops, underlined thing in the middle of roller 4 one sides, roller 4 activities, leather strap 2, gradient groove 3 is in scale groove 1 internal fixation inertia, during use, infusion bottle is hung over the calibrated altitude place, according to the needed flow of medicine, to the graduation mark of corresponding discharge reading, the flow reading of spending at this very moment on the line is the interior medicinal liquid flow velocity of transfusion leather strap with roller 4 slidings.
