Device for controlling liquid flow

Abstract

A device for controlling liquid flow comprises a clamp body, a through hole is formed in the center of the clamp body, a groove is formed in the radial direction from the center of the through hole to the outer edge of the clamp body, the first end and the second end of the clamp body are formed on the two sides of the groove, and the clamp body is arranged in a spiral line mode from the second end to the first end. The flow adjusting mechanism comprises a buckle and a plurality of clamping grooves, the buckle is arranged at the first end, the clamping grooves are arranged inwards along the second end, and the buckle and the clamping grooves can be connected in a clamped mode. Due to the fact that the second end and the first end are arranged in a spiral line mode, when the first end and the second end are extruded, the axial distance between the first end and the second end is increased, the first end circumferentially moves relative to the second end, when the first end reaches the proper clamping groove position, force applied to the first end and the second end is released, the first end and the second end are reset, and the buckle is clamped into the corresponding clamping groove to be fixed. The infusion flow rate can be conveniently controlled by adjusting the position relation between the buckle and the clamping groove, and one-hand operation is facilitated.

Description

Technical Field

[0001] The utility model relates to a flow control device, in particular to a device for controlling liquid flow. Background Art

[0002] Clinically, enema is a common treatment method, which is to use a catheter to insert liquid from the anus through the rectum into the colon to achieve a defecation and gas treatment method. Enema can achieve the following purposes: 1. Stimulate intestinal peristalsis, relieve constipation, and eliminate intestinal flatulence; 2. Use low-temperature solutions to cool down patients with high fever; 3. Clean the intestines to prepare for certain surgeries, examinations or childbirth; 4. Dilute and remove harmful substances in the intestines to reduce poisoning. However, the existing enema device has disadvantages: 1) Its adjustment buckle plays a water-stopping role, causing the hose to switch between liquid flow and locking, and its flow rate cannot be adjusted; 2) The adjustment buckle requires two-handed operation, and it is difficult to control when adjusting the buckle with one hand, and it is very easy to leak and difficult to adjust. Utility Model Content

[0003] In view of the problems raised by the background technology, the utility model studies and designs a device for controlling liquid flow, which is easy to control and operate, and convenient for adjusting the liquid flow rate.

[0004] The technical solution adopted by the utility model is: a device for controlling liquid flow, comprising:

[0005] The clamp body has a through hole at its center, and a groove is radially formed from the center of the through hole to the outer edge of the clamp body, forming a first end and a second end of the clamp body on both sides of the groove, and the clamp body is arranged in a spiral line from the second end to the first end;

[0006] The flow regulating mechanism comprises a buckle and a slot, wherein the buckle is arranged at the first end, and a plurality of slots are arranged inwardly along the second end, and the buckle and the slot can be engaged with each other.

[0007] Furthermore, the first end and the second end are arranged alternately.

[0008] Furthermore, a limiting flange is provided on the edge of the second end along the length direction of the groove.

[0009] Furthermore, the clamp body is rectangular, square, circular or elliptical.

[0010] Furthermore, when the clip body is rectangular or square, the sides away from the first end and the second end are configured as arc structures.

[0011] Furthermore, when the clamp body is rectangular or square, the groove is arranged perpendicular to one side of the clamp body.

[0012] Furthermore, the groove is located at the midline of one of the sides of the clamp body to which it is perpendicular.

[0013] Due to the application of the above technology, compared with the prior art, the utility model has the following good effects: pinching the first end and the second end of the clamp body with one hand, when pinching them together with fingers, the through hole is deformed and shrunk, forming a certain squeeze on the infusion hose, so that its flow rate is reduced; and because the second end is arranged in a spiral line from the first end to the second end, when squeezing the first end and the second end, the axial distance between the first end and the second end increases, so that the first end moves circumferentially relative to the second end, and when it reaches a suitable slot position, the force applied to the first end and the second end is released, the first end and the second end are reset, and the buckle is fixed in the corresponding slot, so that the through hole maintains the clamping of the infusion hose, and the positional relationship between the buckle and the slot can be adjusted to conveniently control the infusion flow rate, which is convenient for one-handed operation.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 5 As shown, a device for controlling liquid flow includes a clamp body 1, a through hole 12 is opened in the center, a groove 13 is radially opened from the center of the through hole 12 to the outer edge of the clamp body 1, a first end 14 and a second end 15 of the clamp body are formed on both sides of the groove 13, and the clamp body is arranged in a spiral line from the second end 15 to the first end 14.

[0022] like Figure 1-6 As shown, the clamp body 1 is rectangular, square, circular or elliptical.

[0023] like Figure 1 , 3 As shown, when the clip body 1 is rectangular or square, the side 16 away from the first end 14 and the second end 15 is set to an arc structure.

[0024] When the clamp body 1 is rectangular or square, the groove 13 is disposed perpendicular to one of the sides 17 of the clamp body 1 .

[0025] The groove 13 is located at the midline of one of the sides 17 of the clamp body 1 to which the groove 13 is perpendicular.

[0026] like Figure 2 , 4 As shown, a limiting flange 151 is provided on the edge of the second end 15 along the length direction of the groove 13, so that the first end 14 and the second end 15 are maintained in a staggered state when not in use, preventing the first end 14 and the second end 15 from being separated and affecting normal operation.

[0027] like Figure 1-5 As shown, the flow regulating mechanism 2 includes a buckle 21 and a slot 22 . The buckle 21 is arranged at the first end 14 , and a plurality of slots 22 are arranged inwardly along the second end 15 . The buckle 21 and the slots 22 can be engaged with each other.

[0028] Instructions for use:

[0029] Insert the infusion hose into the through hole 12 through the groove 13, and pinch the first end 14 and the second end 15 of the clamp body 1 with one hand. Figure 5 The first end 14 and the second end 15 are forced in the direction shown, so that the two move toward each other; because the first end and the second end are arranged in a spiral line, when radial force is applied to the two, the spiral line is deformed, and while the aperture of the through hole 12 becomes smaller, the axial distance between the first end and the second end increases, and the first end 14 and the second end 15 are in an axial separation state. At this time, it is convenient to adjust the length of the horizontal staggered first end and the second end, that is, it is convenient to adjust the aperture size of the through hole 12, and then adjust its clamping force on the hose to achieve the purpose of adjusting the liquid flow rate. Subsequently, the force applied to the first end 14 and the second end 15 is released, and under the action of the spiral line, the second end 15 and the first end 14 are axially close to each other, and the buckle on the first end is inserted into the slot of the second end, so that the through hole 12 maintains the clamping state of the hose, and the flow rate of the infusion hose is controlled.

[0030] In the above process, the buckle 21 can be overlapped and engaged with different slots 22 to adjust the size of the through hole 12 to different degrees and control the liquid flow rate. When adjusted to the innermost slot 22, the catheter is squeezed and deformed until no liquid flows out.

[0031] In actual operation, the flow rate is adjusted according to actual needs.
