Description

Technical Field

[0001] The present invention relates to a flow control regulator for infusion injection, and more particularly to a flow control regulator for infusion injection, which can prevent flow changes by blocking the rotation of an operating roller when adjusting the infusion flow. Background Art

[0002] Intravenous (IV) systems for intravenous infusions, such as Figure 1 As shown, it includes: an infusion bottle 1, which is filled with infusion; an insertion needle 11, which is inserted into the sealing bottle cap of the infusion bottle 1 and allows the infusion to flow out of the infusion bottle 1; a drip chamber 12 (Drip Chamber), which is fixed to the lower end of the insertion needle 11 and drips in the form of a drop 12a (drop, unit: gtt) inside; an injection needle 14, which is inserted into a vein, a tube 13, which connects the drip chamber 12 and the injection needle 14 and serves as an injection channel for the infusion; an infusion flow regulator 15, which is installed in the middle of the tube 13 and can adjust the flow of the infusion.

[0003] Usually, the insertion needle 11 , the drip chamber 12 , the tube 13 , the injection needle 14 and the infusion flow regulator 15 are manufactured into a set, and the manufactured set is called an infusion set 10 .

[0004] In addition, after the infusion set 10 is connected to the infusion bottle 1 and the infusion is injected, when the infusion is continuously injected into the same patient, only the exhausted infusion bottle 1 is replaced.

[0005] In addition, the drip 12a dripping from the inside of the drip chamber 12 is an infusion falling in the form of water drops. The insertion needle 11 and the drip chamber 12 are made to have a certain volume. For example, if it is made to have 20 drips per 1cc, the volume of one drip is 1 / 20cc, and if it is made to have 60 drips per 1cc, the volume of one drip is 1 / 60cc.

[0006] Therefore, if the period of the drip falling from the inside of the drip chamber 12 is measured, the flow rate of the infusion injected through the infusion set 10 can be calculated.

[0007] On the other hand, when the infusion is injected into the patient, a prescription for the infusion flow rate is issued according to the type of infusion, the type of medicine mixed in the infusion, the patient's condition, the type of disease, etc., so the infusion flow regulator 15 is adjusted in the form of injection at the prescribed flow rate.

[0008] Here, if the injected infusion flow rate does not meet the prescribed flow rate, it may cause a medical accident if one is not careful, so infusion flow rate regulation is very important. The infusion flow regulator 15 includes an operating part 15a for adjusting the cross-sectional area of ​​the infusion through the tube 13, so the injection flow rate of the infusion can be adjusted by operating the operating part 15a.

[0009] like Figure 1 The infusion flow regulator 15 shown in the figure is also called a roller clamp, and the operating part 15a is set to a roller type. If you look closely, after the tube 13 is inserted into the upper and lower open grooves 15b and penetrates, the operating part 15a of the pressing tube 13 is guided to the long groove 15c and can move up and down.

[0010] Here, the depth of the groove 15b becomes shallower toward the lower part, and the more the operating part 15a moves downward, the more the tube 15 is pressed. Therefore, while the operating part 15a moves, the flow rate at each moving position is measured, and the movement of the roller 15a is stopped when the desired flow rate is reached. In this way, the input injection flow rate is adjusted.

[0011] However, if Figure 1 The roller clamp type infusion flow regulator 15 shown has to measure the flow rate by looking at the drip chamber 12 every time the roller type operating part 15a is moved, so tedious measurement work needs to be repeated, and the accuracy of flow regulation is also reduced.

[0012] In addition, conventional infusion flow regulators adjust the infusion flow rate by moving a roller-type operating part up and down, but there is no separate locking device after the operating part is operated, thereby causing the following problem: when the patient continues to move or accidentally touches the operating part, the operating part will move unintentionally, causing the infusion flow rate to deviate from the set value, thereby causing a medical accident. Summary of the invention

[0013] Therefore, the present invention is proposed to solve the above-mentioned problems, and its purpose is to provide a flow control regulator for infusion injection, which connects a roller bracket for supporting an operating roller to a main body for inserting an infusion tube, thereby preventing the operating roller for adjusting the infusion volume from wandering at an adjusted position, and marking a flow scale, so that the infusion can be discharged safely and accurately according to the set amount, thereby improving product performance, safety of use and user trust.

[0014] In order to achieve the above-mentioned purpose, a flow control regulator for infusion injection according to an embodiment of the present invention may include: a main body, in which an infusion tube is inserted in an up-and-down manner and a roller connecting groove is formed on the front; an operating roller, which is inserted into the roller connecting groove of the main body and presses the tube while moving up and down, thereby adjusting the flow; and a roller bracket, which is connected to the main body for inserting the operating roller and supports the operating roller in a manner that prevents the operating roller from moving arbitrarily.

[0015] The flow rate adjustment scale can be marked on the main body so that the flow rate of the infusion discharged as the operating roller moves can be confirmed.

[0016] The roller bracket may include: an inserting portion, which is combined with the roller connecting groove; and a movement preventing portion, which is arranged on the front side of the inserting portion and is closely attached to a side surface of the operating roller, thereby blocking the movement of the operating roller.

[0017] The insertion portion may include an insertion piece, which is inserted into the roller connecting groove and moves up and down in the roller connecting groove, and a hanging piece is arranged on the outer side of the end of the insertion piece so that it can be hung on the inner side of the roller connecting groove to prevent the roller bracket from falling off.

[0018] A plurality of inserting pieces can be provided in a form of being closely attached to the inner wall surfaces on both sides of the roller connecting groove.

[0019] The movement preventing portion may be formed as a " " shape so that the outer periphery of the operating roller can be inserted and fit tightly.

[0020] In order to make the roller bracket close to the operating roller, a plurality of moving protrusions can be provided on the front side of the movement prevention portion in the form of protruding upwards, so that the roller bracket can be easily moved along the roller connecting groove.

[0021] The roller bracket may include: a connecting portion, which is inserted into the roller connecting groove and connected to the operating roller; and a locking portion, which is arranged on the side of the connecting portion and is hooked on the outer side of the body to prevent the roller bracket from moving, thereby locking the operating roller.

[0022] The connecting part may include: a movable plate, which is tightly attached to the upper part of the main body and is formed with an insertion groove in the form of a part of the operating roller being inserted and protruding; and a connecting rod, which is arranged on both sides of the lower part of the movable plate and is formed with a fixing groove so that the rotating shaft of the roller can be inserted into the roller connecting groove and at the same time, so that the roller bracket can move together with the operating roller.

[0023] The locking parts are arranged on both side surfaces of the connecting part, and a locking ring can be arranged at the lower part so as to be hung on the hanging ridge formed on the outer side surface of the main body, so that the roller bracket can be locked on the main body.

[0024] The locking portion may be connected in a flexible form so as to be smoothly rotated upward and downward from the connection portion.

[0025] As described above, according to the flow control regulator for infusion injection of the present invention, a roller bracket for temporarily stopping the movement of the operating roller is installed on the main body for inserting the infusion tube, so as to prevent the operating roller for adjusting the infusion amount through the roller bracket from being locked in the moved position in a form of arbitrarily moving. Even if the patient continues to move or accidentally touches the operating roller, the operating roller will not move easily, so that the set infusion amount is discharged constantly to prevent medical accidents and maximize the efficiency of the product.

[0058] like Figures 2 to 7 As shown, the flow control regulator for infusion injection according to the present invention includes a main body 100 , an operating roller 200 , and a roller bracket 300 .

[0059] The main body 10 is formed with a space portion 110 in a through-going manner, into which an infusion tube 13 for supplying infusion is inserted and connected, and a roller connection groove 120 may be formed on the front side so that the operating roller 200 can be connected.

[0060] At this time, the bottom surface of the space portion 110 may be formed in an inclined form so that the pressing depth of the infusion tube 13 can be adjusted according to the movement of the operating roller 200 .

[0061] In addition, a hanging ridge 130 may be formed on the outer side of the body 100 .

[0062] A flow rate adjustment scale 140 may be marked on the side of the body 100 so that the flow rate of the infusion discharged through the infusion tube 13 as the operating roller 200 moves can be confirmed.

[0063] The operating roller 200 is inserted into the roller connection groove 120 of the body 100 and moves up and down while pressing the infusion tube 13, so that the flow rate can be adjusted.

[0064] In addition, a rotating shaft 210 may be formed on both sides of the operating roller 200 so as to be inserted into the side of the roller connecting groove 120 , so that the operating roller 200 moves up and down along with the roller connecting groove 120 .

[0065] The roller support 300 is inserted into the roller connection groove 120 of the body 100 and is closely attached to one side of the operating roller 200, thereby supporting the operating roller 200 in a manner that prevents the operating roller 200 from moving arbitrarily.

[0066] like Figure 2 and Figure 6 to Figure 7 As shown, the roller bracket 300 includes an insertion portion 310 and a movement preventing portion 320.

[0067] The inserting portion 310 is inserted into the roller connecting groove 120 of the body 100 and can move up and down.

[0068] The inserting portion 310 includes an inserting piece 311 which is inserted into the roller connecting groove 120 and moves up and down in the roller connecting groove 120 .

[0069] In addition, a plurality of inserting pieces 311 may be provided in a form of being closely attached to the inner wall surfaces on both sides of the roller connecting groove 120 .

[0070] In other words, a plurality of insertion pieces 311 are provided for inserting into the roller connecting groove 120 , and are closely attached to the inner wall surfaces on both sides of the roller connecting groove 120 , so that the roller bracket is not easy to move in the roller connecting groove 120 unless the administrator adjusts it.

[0071] A hanging piece 312 may be provided at the outer side of the end of the inserting piece 311 , and the hanging piece 312 is hung on the inner side of the roller connecting groove 120 to prevent the roller bracket 300 from being separated from the roller connecting groove 120 .

[0072] In addition, the hanging piece 312 is formed to protrude outward from the insertion piece 311 and may be formed in a “∠” shape so as to be easily inserted into the roller connecting groove 120 but not fall off.

[0073] The movement preventing portion 320 is disposed on the front side of the inserting portion 310 and is closely attached to a side surface of the operating roller 200 , thereby preventing the operating roller 200 from moving.

[0074] In addition, if Figure 4 As shown, the movement preventing portion 320 may be located above the operating roller 200 .

[0075] In other words, when the operating roller 200 moves downward, the pressing force of the infusion tube 13 gradually becomes stronger and the infusion volume gradually decreases, so that the operating roller 200 is not easy to move downward, but can move upward, thereby making the roller bracket 300 located above the operating roller 200.

[0076] The movement preventing portion 320 may be configured to form a support groove 321 on the inner side surface. ” shape so that one side periphery of the operating roller 200 can be inserted and tightly attached, thereby blocking the movement of the operating roller 200.

[0077] Furthermore, in order to block the movement of the operating roller 200 by making the roller holder 300 closely attached to the operating roller 200 , a moving protrusion 322 may be provided on the front surface of the movement prevention portion 320 in a form that can be easily moved along the roller connecting groove 120 and closely attached to the operating roller 200 .

[0078] In addition, a plurality of the moving protrusions 322 may be provided in the form of being protruded upward.

[0079] In addition, as another embodiment of the present invention, Figures 8 to 14 As shown, the roller bracket 301 includes a connecting portion 330 and a locking portion 340.

[0080] The connection portion 330 may be inserted into the roller connection groove 120 , connected to the operating roller 200 , and moved together with the operating roller 200 .

[0081] The connecting portion 330 includes a moving plate 331 and a connecting rod 332 .

[0082] The movable plate 331 is closely attached to the upper surface of the body 100 , and an insertion groove 331 a is formed inside the movable plate 331 in a manner that allows the protruding portion of the operating roller 200 protruding upward to be inserted into the roller connecting groove 120 and inserted therein.

[0083] In other words, when the moving plate 331 is closely attached to the body 100 and the operating roller 200 is inserted into the insertion groove 331 a , the moving plate 331 may move together with the movement of the operating roller 200 .

[0084] The connecting rod 332 is vertically arranged on both sides of the lower part of the moving plate 331 , and is inserted into the roller connecting groove 120 , and at the same time, is inserted into the rotating shaft 210 of the operating roller 200 and fixed to the operating roller 200 , thereby moving the roller bracket 301 together with the operating roller 200 .

[0085] In addition, a fixing groove 332 a may be formed at a lower portion of the connection rod 332 so that the rotating shaft 210 of the operating roller 200 may be inserted.

[0086] In other words, while the connecting rod 332 is inserted between the roller connecting groove 120 and the operating roller 200, the rotating shaft 210 is inserted into the fixing groove 332a, so that the connecting rod 332 and the operating roller 200 are connected, whereby the operating roller 200 and the roller bracket 301 can move simultaneously.

[0087] The locking portion 340 is disposed on a side surface of the connecting portion 330 and is hung on a hanging portion 130 formed on an outer side surface of the body 100 as it rotates, thereby preventing the roller bracket 301 from moving and locking the operating roller 200 .

[0088] In addition, the locking portion 340 may be disposed on both side surfaces of the connecting portion 330 .

[0089] A locking ring 341 may be provided at the lower portion of the locking portion 340 so as to be hooked on a hooking cutter 130 formed on the outer side of the body 100 , thereby enabling the roller bracket 301 to be locked on the body 100 .

[0090] At this time, the locking ring 341 may be formed by bending a cut portion formed by cutting a portion of the locking portion 340 downward.

[0091] Furthermore, the locking portion 340 may be connected in a flexible form so that the connection portion with the connection portion 330 can be smoothly rotated upward and downward from the connection portion 330 , thereby locking or unlocking the roller bracket 301 to the body 100 .

[0092] The operating state of the flow rate control regulator for infusion injection according to the present invention having the above-mentioned structure is observed as follows.

[0093] The operating roller 200 is connected to the roller connecting groove 120 of the main body 100 for inserting the infusion tube 13, and the roller brackets 300 and 301 are inserted into the roller connecting groove 120 connected with the operating roller 200, so that the movement of the operating roller 200 moving in the roller connecting groove 120 can be blocked by the roller brackets 300 and 301.

[0094] Furthermore, the roller supports 300, 301 inserted into the roller connecting groove 120 support or lock the operating roller 200, so that the operating roller 200 adjusted according to the set infusion volume will not move arbitrarily unless the administrator operates it, so the infusion volume can always be discharged constantly according to the set volume.

[0095] At the same time, a flow adjustment scale 140 is marked on the side of the main body 100, so the administrator does not need to roughly confirm the infusion volume generated by the movement of the operating roller 200 with the naked eye, but can accurately confirm it through the flow adjustment scale 140, so that the infusion volume can be discharged according to the prescription, which can maximize the product efficiency.

[0096] In addition, the roller brackets 300 and 301 can be easily assembled and separated from the roller connecting groove 120 of the main body 100, so that they can be easily disassembled as needed, thereby improving convenience.

[0097] As described above, the present invention is not limited to the above-mentioned specific preferred embodiments. Without departing from the gist of the present invention as claimed in the claims, it is natural that anyone with general knowledge of the technical field to which the present invention belongs can carry out various modified implementations, and such changes are within the scope recorded in the claims.
