Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an infusion set flow regulator. Background Art

[0002] The infusion flow regulator is used in the process of regulating the flow of liquid medicine. Using the regulator to control the precise flow can give full play to the effect of the liquid medicine and reduce the adverse reactions of excessive infusion to the human body. According to the prior art, such as the infusion flow regulator with a one-button switch described in Chinese patent document CN201821486379.1, the disclosed technical solution is to add a push button switch and mark it in Chinese for the convenience of the elderly to identify. The function of the push button switch is to control the stop and resumption of infusion at any time, further prevent accidents from happening, and greatly improve the clinical work efficiency of medical staff.

[0003] According to the technical solution disclosed by the infusion device, the flow regulator in the prior art realizes the flow regulation process by moving the rubbing wheel to produce different degrees of squeezing effect on the surface of the input pipe. However, since the input pipe is a hose structure, after the rubbing wheel is squeezed at the same position for a long time, even if the rubbing wheel is removed to increase the flow, the input pipe will still be unable to recover due to the long-term squeezing, thus affecting the subsequent flow regulation effect. On the other hand, the specific regulated flow value cannot be accurately and intuitively judged. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an infusion flow regulator to solve the problems raised in the above-mentioned background technology. The utility model can avoid the situation where the pipeline cannot be restored after maintaining a flow state for a long time, and the flow value after regulation is more intuitive.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: an infusion flow regulator, including a flow regulator body, the flow regulator body including a shell, an adjustment mechanism, a diverter hose and a throttling assembly, the top and bottom of the shell are provided with diverter bins, the diverter bin at the top of the shell is connected to an input pipeline, the diverter bin at the bottom of the shell is connected to an output pipeline, the diverter bins are connected by multiple diverter hoses, and an independent throttling assembly is installed on the surface of each diverter hose, and the adjustment mechanism is installed on the surface of the throttling assembly.

[0006] Furthermore, a back plate is provided inside the shell, a plurality of bosses are provided on the surface of the back plate, a diversion hose is mounted on the surface of each boss, and gaps are provided between adjacent bosses.

[0007] Furthermore, each of the diverter hoses is provided with through holes at the top and bottom, and the diverter hose is connected with the interior of the diverter bin through the through holes, and the width of each gap is the same.

[0008] Furthermore, the throttling assembly includes a clamping plate and an inclined plate, an adhesive plate is provided at the rear end of the inclined plate, a pull rod is provided on one side of the adhesive plate, and a magnet sheet is installed at the end of the pull rod.

[0009] Furthermore, a slide groove is provided on the inner side of the splint, a magnetic plate is installed at the end of the slide groove, the magnetic sheet is embedded in the slide groove, and the magnetic sheet and the magnetic plate are adsorbed and fitted, the pull rod passes through the middle of the two magnetic sheets, and a splint is installed inside each of the gaps.

[0010] Furthermore, the number of the throttling components and the diverter hose is the same, and the installation height of each throttling component is different, and the inclined plate is attached to the surface of the diverter hose through the adhesive plate at the rear end.

[0011] Furthermore, the adjustment mechanism includes a lifting slot and an extrusion plate, the lifting slot is opened on the surface of the shell, a linkage column is inserted into the interior of the slot, the extrusion plate is installed at the end of the linkage column, and a push plate is installed at the front end of the linkage column.

[0012] Furthermore, the push plate is pressed against the surface of the shell, and a marking line is printed on the shell on the side of the lifting slide groove. The rear end of the push plate is pressed and contacted with the surface of the inclined plate after the lifting movement.

[0013] Beneficial effects of the utility model:

[0014] The infusion flow regulator uses the diversion chamber to transfer the liquid medicine in the input pipeline into multiple independent diversion hoses respectively, and controls the adjustment mechanism to move downward, and cooperates with the throttling components at different heights to seal the diversion hoses one by one, so as to achieve a multi-level control effect on the flow rate. The actual flow rate after adjustment is accurate and reliable, and can be judged more intuitively without the need for verification.

[0015] In each throttling component of the infusion set flow regulator, each is bonded and connected to the surface of the shunt hose through an adhesive plate. Therefore, even if the shunt hose is squeezed for a long time, as long as the squeezing effect is released, the throttling component can be pushed outward by the magnetic structure, and then the squeezed position on the surface of the shunt hose can be pulled outward by the adhesive plate to expand, thereby preventing the hose from maintaining an squeezed and deformed state for a long time, thereby improving the effectiveness and reliability of regulation.

[0016] After the infusion flow regulator completes the adjustment, since each diversion hose can only achieve two states: fully open or fully closed, it can avoid the problem of a small amount of liquid medicine continuing to flow downward due to loose closure after adjustment. Therefore, it can ensure that the flow rate after adjustment can accurately reach the set flow rate for delivery, thereby improving the adjustment accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4The utility model provides a technical solution: an infusion flow regulator, comprising a flow regulator body, the flow regulator body comprising a shell 1, an adjusting mechanism 5, a shunt hose 9 and a throttling assembly 6, the top and bottom of the shell 1 are both provided with a shunt bin 3, the shunt bin 3 at the top of the shell 1 is connected to an input pipe 2, the shunt bin 3 at the bottom of the shell 1 is connected to an output pipe 4, the shunt bins 3 are connected by a plurality of shunt hoses 9, and an independent throttling assembly 6 is installed on the surface of each shunt hose 9, the adjusting mechanism 5 is arranged Installed on the surface of the throttling component 6, the infusion flow regulator is installed on the infusion set, and the drug solution flows into the input pipe 2 through the infusion tube, enters into the multiple shunt hoses 9 inside the shell 1 through the input pipe 2 and the shunt chamber 3, and flows downward along the shunt hoses 9 until it enters the shunt chamber 3 at the bottom of the shell 1, and finally flows out from the output pipe 4, and is delivered to the patient's body from the syringe at the end of the infusion set, while the shunt hoses 9 inside the shell 1 trigger the throttling component 6 through the adjustment mechanism 5 to control the number of shunt hoses 9 used.

[0024] In this embodiment, a back plate 7 is provided inside the housing 1, and a plurality of bosses 8 are provided on the surface of the back plate 7. A diverter hose 9 is mounted on the surface of each boss 8, and gaps 10 are provided between adjacent bosses 8. Through holes 11 are provided on the top and bottom of each diverter hose 9, and the diverter hose 9 is connected to the inside of the diverter bin 3 through the through holes 11, and the width of each gap 10 is the same. After the adjustment is completed, since each diverter hose 9 can only be fully opened or fully closed, the problem of a small amount of liquid medicine continuing to flow downward due to lax closure after adjustment can be avoided, so that the flow rate after adjustment can be ensured to accurately reach the set flow rate for delivery, thereby improving the adjustment accuracy. Specifically, each diverter hose 9 inside the shell 1 is in an independent state, and the surface of each diverter hose 9 is covered with a corresponding throttling component 6. When in use, the throttling component 6 is located close to the surface of the shell 1, so the corresponding diverter hose 9 is not squeezed at all, and can directly transfer the medicine inside the top diverter bin 3 to the bottom. After the throttling component 6 is controlled by the adjustment mechanism 5 to squeeze the diverter hose 9, the diverter hose 9 can be directly completely sealed, which can completely prevent the diverter hose 9 from transferring the medicine, thereby achieving the control effect of the total flow rate of the medicine.

[0025] In this embodiment, the throttling assembly 6 includes a clamping plate 12 and an inclined plate 17, an adhesive plate 18 is provided at the rear end of the inclined plate 17, a pull rod 16 is provided on one side of the adhesive plate 18, a magnet sheet 15 is installed at the end of the pull rod 16, a slide groove 13 is provided on the inner side of the clamping plate 12, a magnetic plate 14 is installed at the end of the slide groove 13, the magnet sheet 15 is embedded in the interior of the slide groove 13, and the magnet sheet 15 and the magnetic plate 14 are adsorbed and fitted, the pull rod 16 passes through the middle of the two magnet sheets 15, a clamping plate 12 is installed inside each of the gaps 10, the number of the throttling assemblies 6 and the diversion hose 9 is the same, and the installation height of each throttling assembly 6 is different, and the inclined plate 17 is attached to the surface of the diversion hose 9 through the adhesive plate 18 at the rear end. In each throttling component 6, it is fitted and connected to the surface of the diverter hose 9 through an adhesive plate 18. Therefore, even if the diverter hose 9 is squeezed for a long time, as long as the squeezing effect is released, the throttling component 6 can be pushed outward by the magnetic structure, and then the squeezed position on the surface of the diverter hose 9 can be pulled outward by the adhesive plate 18 to expand, thereby avoiding the hose from maintaining an squeezed and deformed state for a long time, thereby improving the effectiveness and reliability of regulation.

[0026] Specifically, after the adjusting mechanism 5 moves downward, the inclined structure on the surface of the inclined plate 17 can be cooperated to push the entire inclined plate 17 toward the rear end, and the position contacted by the diverter hose 9 can be squeezed backward through the adhesive plate 18, and finally, the part of the protruding column 8 fixed at the rear end can be cooperated to achieve the effect of closing the diverter hose 9. When the adjusting mechanism 5 moves upward from the position of the throttling component 6, the throttling component 6 is not blocked, and the magnetic sheet 15 is adsorbed onto the magnetic suction plate 14, driving the inclined plate 17 to move outward, and then pulling the squeezed position of the diverter hose 9 to expand toward the outside through the adhesive plate 18, thereby achieving the effect of restoring deformation.

[0027] In this embodiment, the regulating mechanism 5 includes a lifting chute 19 and a squeeze plate 22. The lifting chute 19 is provided on the surface of the housing 1. A linkage column 20 is inserted into the interior of the chute 13. The squeeze plate 22 is installed at the end of the linkage column 20. A push plate 21 is installed at the front end of the linkage column 20. The push plate 21 is pressed against the surface of the housing 1. An identification line 23 is printed on the housing 1 on the side of the lifting chute 19. The rear end of the push plate 21 is squeezed and contacted with the surface of the inclined plate 17 after the lifting movement. The liquid medicine in the input pipeline 2 is respectively introduced into a plurality of independent split hoses 9 through the split chamber 3. By controlling the regulating mechanism 5 to move downward, the split hoses 9 are sealed one by one in cooperation with the throttling components 6 at different heights, so that a multi-level control effect of the flow rate can be achieved. The actual flow rate after adjustment is accurate and reliable, and can also be judged more intuitively without the need for verification.

[0028] Specifically, by pushing the push plate 21 downward, the extrusion plate 22 can be moved downward, so that during the movement process, each throttling component 6 can be contacted one by one to complete the above-mentioned closing process, and the number of closed diversion hoses 9 can be judged through the corresponding position of the push plate 21 and the side identification line 23, so that the flow judgment is faster and more intuitive.
