Description

Cylinder type fluid flow control device

The present invention relates to a cylindrical infusion fluid control device, and more particularly, to an automatic infusion fluid flow rate control device capable of automatically adjusting the flow rate of the infusion fluid.

In order to maintain/replenish fluids, electrolytes, vitamins, proteins, fats and calories, or to maintain adequate blood composition in patients who are not normally able to adequately receive essential nutrients orally, or to rapidly supply drugs in emergency situations In order to do this, the hospital injects an intravenous fluid or drug into the patient's vein.

At this time, an IV (intravenous injection) set is commonly used as an essential item, and a fluid regulator is used to control the amount of fluid supplied to the patient.

When administering the drug, it is necessary to provide a change in the administration time of the drug depending on the circumstances. For example, in order to prevent blood clots and blockage of the fluid, a method of gradually reducing the supply of fluid after turning on the maximum amount of fluid for a certain period of time is sometimes used. However, this type of fluid supply control is manually controlled by the medical staff, but in actual clinical practice, the fluid is often over-administered because the timing of fluid adjustment is missed while doing other work with the fluid turned on to the maximum.

1 to 3, the cylindrical infusion control device 10 according to an embodiment of the present invention is a cylindrical infusion control that can adjust the flow rate of the infusion fluid by adjusting the strength of the pressing of the infusion tube over time. The device 10 includes a case 110 , a cylinder 120 , an elastic body 130 , a movable body 140 , and a piston 150 .

The case 110 is formed to be opened in the lateral direction so that the cylinder 120 can be mounted.

The cylinder 120 has an accommodating space therein, and a first through-hole 121 and a second through-hole 122 are formed at both ends, so that the receiving space is filled with oil (O) and coupled to the case 110 . do.

The elastic body 130 is disposed in the receiving space, and is preferably disposed between the upper inner peripheral surface of the cylinder 120 and the upper surface of the piston 150 to be compressed according to the movement of the movable body 140 .

The movable body 140 has one end extending upward through the first through hole 121 , and the other end extending downward through the second through hole 122 to move along the axial direction of the cylinder 120 .

The piston 150 is coupled to the outer circumferential surface of the movable body 140 , and is coupled to the movable body 140 so as to contact the lower surface of the elastic body 130 so that the movable body 140 contacts the elastic body 130 when the movable body 140 moves in one direction. ) is compressed, and when moving in the opposite direction by the restoring force of the elastic body 130, the oil of the cylinder 120 in which the elastic body 130 is accommodated is guided to move to the other receiving space. Through this, the movable body 140 may change the amount of infusion fluid to be moved according to time, thereby changing the degree of pressing the infusion tube T according to time. In this case, the piston 150 may be integrally formed with the movable body 140 .

Hereinafter, each configuration will be described in more detail.

Each configuration will be described in detail with reference to FIGS. 4 to 7 , and for necessary details, refer to FIGS. 1 to 3 .

The case 110 is opened in the lateral direction so that the cylinder 120 can be mounted, and includes a fixed body 111 , an intermediate partition wall 112 , and a cutout groove 113 .

The fixed body 111 is formed so that both sides are opened so that the cylinder 120 can be inserted and fixed. The upper end of the fixed body 111 may be formed with a step 1111 so that the inner diameter of the first adjustment knob 161 is widened to the outside so that the first adjustment knob 161 can be disposed.

The intermediate partition wall 112 is disposed along the horizontal direction at the lower end of the fixed body 111 to accommodate a cylinder accommodating space S1 capable of accommodating an upper cylinder and an adjustment knob accommodating space capable of accommodating the input amount control knob 170 . (S2). At this time, a hole 1121 may be formed on the inner circumferential surface of the intermediate angular wall 122 so that the tightening control hole 172 of the input amount adjustment knob 170 disposed in the adjustment knob accommodating space S2 passes through and extends upward. there is. The hole 1121 is not formed in a circular shape, but an approximate shape is formed in a shape such as a yaw (凹), and one side to which the tightening control member 172 is coupled may be formed in a shape corresponding thereto. Accordingly, the tightening control member 172 coupled to the hole 1121 may not be easily separated even in frequent contact with the infusion pipe T.

The incision groove 113 is formed at both ends of the side wall so that the infusion tube T can be fitted and seated at the lower end of the side wall of the fixed body 111 integrally formed with the upper end of the intermediate partition wall 112 . The infusion tube (T) is fixed so as not to move by being fitted at both ends of the incision groove (113). The incision groove 113 is preferably formed to have a width smaller than the diameter of a normal infusion tube (T).

The cylinder 120 is formed in a cylindrical shape and an accommodation space is formed therein, and the oil (O) is filled in the accommodation space, and it is preferable to be completely filled so that air does not enter.

In addition, grooves are formed in each of the first through-holes 121 and the second through-holes 122 respectively formed at both ends of the cylinder 120 , and sealing materials 1211 and 1212 are coupled to the inner circumferential surface of the grooves inside the accommodation space. It is possible to form an airtight structure so that the oil (O) contained in it does not leak out.

The elastic body 130 is disposed in the receiving space of the cylinder 120 . The elastic body 130 may be formed of a coil spring, and is disposed to abut against the upper surface of the piston 150 coupled to the outer circumferential surface of the movable body 140 . The elastic body 130 is formed to have a relatively smaller length than the axial length of the receiving space of the cylinder 120, and is compressed by contacting the piston 150 according to the movement of the movable body 140, or as the compressed state is restored. Together with 150 , the movable body 140 may be moved in the opposite direction. In the present invention, the elastic body 130 is exemplified as a coil spring, but as long as it has a structure capable of moving in contact with the piston 150 through compression and restoration, various deformations may be applied.

The movable body 140 is formed in a cylindrical rod shape extending in one direction, and both ends extend through the first through-hole 121 and the second through-hole 122 of the cylinder, respectively.

A screw thread 141 is formed at one end of the movable body 140 passing through the first through hole 121 , and the first adjustment knob 161 is coupled to the screw thread 141 . At this time, the screw thread 141 formed on the movable body 140 may be formed of a multiple thread screw, preferably a triple thread screw. For example, if a multiple thread screw is formed as a triple thread screw, the time is adjusted to move 3 mm along the axial direction because the lead is formed three times the pitch. It is enough to turn the knob 161 only one turn. Accordingly, in the present invention, the axial length of the movable body 140 can be shortened through a multiple thread screw, thereby making the overall structure more compact. If the screw thread is formed as a single thread screw, the axial length of the screw thread becomes longer because the time adjustment knob 161 has to be turned three times to move 3 mm, thereby increasing the overall shape. . In the present invention, although it has been described that a multiple thread screw is formed as a triple thread screw as an example, it may be formed in two or more rows, but is not limited thereto.

The other end of the movable body 140 passing through the second through hole 122 is disposed on the upper surface of the intermediate partition wall 112 to form a pressing hole 142 to press the infusion tube T. The pressing sphere 142 may have an approximate shape and an approximate groove 1421 may be formed, and may be formed protruding from the center to more effectively press the infusion tube (T).

Through this, it is possible to adjust the amount of fluid flowing through the infusion tube T to decrease as the degree of pressing of the infusion tube T increases with time.

The piston 150 is coupled to the outer circumferential surface of the movable body 140 located inside the cylinder 120 to compress the elastic body 130 or the oil (O) accommodated in the cylinder 120 according to the restoration of the elastic body 130 . ), which can control the amount of movement, may include a body 151 , an O-ring 152 and an oil cover 153 . The piston 150 may be integrally formed on the outer peripheral surface of the movable body 140 .

The body 151 is formed in a plate-shaped cylindrical shape and is coupled to the outer circumferential surface of the movable body 140 , and includes a plurality of holes 1512 and 1513 , and a receiving groove 1514 .

The plurality of holes 1512 and 1513 may be formed of the first hole 1512 and the second hole 1513 and may be provided in at least one axial direction of the cylinder 120 . In this case, the first hole 1512 may be formed relatively more than the second hole 1513 , and may be formed to have a larger size. At this time, the first hole 1512 communicates with or does not communicate with the oil 0 positioned below the piston 150 according to the driving state of the oil cover 153 to be described later. When the first hole 1512 is larger and more formed than the second hole 1513 , the oil O located on the upper side of the cylinder 120 is rapidly moved to the lower side to increase the operating efficiency. Conversely, the second hole 1513 is formed to be smaller and smaller than the first hole 1512, so that the oil O located on the lower side can be moved to the upper side later, and this feature will be described later. Described specifically.

The receiving groove 1514 is formed in a groove shape concave upward so that the oil cover 153 can be coupled to the bottom surface of the body 151, and between the oil cover 153 and the body 151 disposed therein. Adhesion can be increased.

The O-ring 152 is coupled to the stepped groove 1511 on the outer circumferential surface of the body 151 to be in close contact with the inner circumferential surface of the cylinder 120 to prevent the oil O from leaking along the contact surface of the piston 150 .

The oil cover 153 is formed in a plate shape and can be coupled to the bottom surface of the body 151 on which the elastic body 130 is disposed, and includes a third hole 1531 and an oil cover fixing hole 1532 .

The third hole 1531 is formed at the same position as the position where the second hole 1513 is formed, and is formed in the same or larger size than the second hole 1513 to communicate the upper space and the lower space of the cylinder 120 . can

The oil cover fixing hole 1532 is disposed to face each other in the radial direction on the oil cover 153 and is coupled to the receiving groove 1514 of the body 151 . Since the oil cover 153 is coupled through the oil cover fixing hole 1532 disposed to face in the radial direction, the first rotation section and the second rotation are in both directions about the axis X of the oil cover fixing hole 1532 . section can be formed. At this time, the body 151 is formed with a groove or a hole corresponding to the oil cover fixing hole 1532 and is coupled to the oil cover fixing hole 1532 through the fixing tool 1515 to maintain a solid fastening state.

The characteristics of the oil cover 153 coupled to the body 151 and mutually driven will be described in more detail as follows.

The oil cover 153 maintains a state in close contact with the receiving groove 1514 before the time adjustment furnace 161 is driven. Then, when the movable body 140 moves upward through the time adjustment knob 160, the piston 150 coupled to the movable body 140 moves upward while compressing the elastic body 130 and the elastic body 130 is positioned. The oil cover 153 that was in close contact with the bottom surface of the body 151 while the oil O accommodated on the side moves in the other direction of the body 151 in which the elastic body 130 is located is the oil cover fixing hole 1532. It moves in the downward direction of the piston 150 while rotating in both directions about the axis (O). Accordingly, the oil O moves along the first hole 1512 and the second hole 1513 .

Then, when the movement of the movable body 140 is stopped, the oil cover 153 comes into close contact with the bottom surface of the body 151 again in the rotated state. At this time, the oil cover 153 has a third hole 1531 formed at the same position as the position where the second hole 1513 is formed, so that the oil O can move, but the position where the first hole 1512 is formed. is closed, so that the oil O cannot move through the first hole 1512, so that the inflow speed and the outflow speed are different. That is, as the compression state of the elastic body 130 is restored, the oil O moves only through the second hole 1513 and the third hole 1531 , and as the movable body 140 moves downward, the infusion tube T ) will change the pressure.

At this time, since the second hole 1513 is relatively small compared to the first hole 1512, the amount of oil (O) moving in the downward direction can slow down the moving speed of the movable body 140, and By slowly increasing the degree of pressing of the infusion tube T through the movable body 140 , it is possible to reduce the amount of the infusion fluid moving along the infusion tube T. Then, when the elastic body 130 is completely moved to the preset position, the fluid moving along the infusion tube moves at the lowest speed.

Therefore, it is inconvenient to continuously monitor the patient's condition in order to control the amount of infusion because the injection amount of the infusion can be decreased according to a certain time, and the movement speed of the fluid can be maintained to be injected at the lowest speed after a certain period of time. can be removed.

The time adjustment knob 160 is disposed on the upper end of the cylinder 120 and is coupled to the screw thread 141 of the movable body 140 to move the movable body upward to compress the elastic body 130 , and the first control knob (161) and a spring spring 162 may be provided.

The first adjustment knob 161 is formed in a disk shape, a hole 1611 is formed in the center, is coupled to the screw thread 141 formed in the movable body 140, and a receiving space 1612 is formed on the lower surface. And, the first control knob 161 is seated on the step 1111 formed at the top of the case 110 is exposed in both directions to operate rotatably. In addition, a plurality of grooves are formed on the outer peripheral surface of the first adjustment furnace 161 to increase frictional force when in contact with the hand so that it can be operated without slipping.

The spring spring 162 is disposed and coupled to the receiving space 1612 formed on the lower surface of the first adjustment knob 161, so that when the first adjustment knob 161 rotates in one direction, the spring spring 162 is compressed while being wound. become a state At this time, when the one-way rotation of the first adjustment knob 161 is stopped, the spring spring 162 provides a restoring force to rotate in the opposite direction to the rotational direction of the first adjustment knob 161 while the winding state is released to provide the first adjustment The knob 161 may be restored to its original position. Therefore, there is no need to take a separate action to move the first adjustment furnace 161 to the original position.

The input amount control knob 170 is disposed in the control knob accommodating space S2 formed through the intermediate partition wall 112 at the lower end of the cylinder 120, and includes a second control knob 171 and a tightening control member 172. do.

The second control knob 171 is formed in a disk shape, and a hole 1711 is formed on the inner circumferential surface to be disposed in the control knob accommodating space S2 to operate rotatably. At this time, a screw thread (not shown) is formed in the hole 171 , and the screw thread of the tightening control member 172 may be coupled thereto. In addition, the second adjustment furnace 111 has a plurality of grooves formed on its outer peripheral surface to increase friction when it comes into contact with the hand so that it can be operated without slipping.

The screw thread is formed so that one end is coupled to the screw thread formed in the hole 1711 formed in the second adjustment knob 171 , and the other end is disposed to pass through the hole 1121 formed in the intermediate partition wall 112 . A protrusion 1721 is formed. Accordingly, the tightening control member 172 moves up and down according to the rotational operation of the second control knob 171 and controls the tightening amount of the infusion tube T together with the pressing member 142 coupled to the other end of the movable body 140 . can be adjusted

As such, the cylindrical infusion control device 10 according to the present invention can automatically adjust the flow rate of the infusion, and even if a nurse or doctor forgets to adjust the flow rate of the infusion, over time, the patient has an excessive amount of infusion. It can be prevented from being administered, so that it is possible to provide safe fluid administration.
