Description

Technical Field

[0001] The utility model relates to the technical field of medicine pushing speed regulators, in particular to a timing automatic medicine pushing speed regulator. Background Art

[0002] A drug push speed controller is a device used to control the speed at which drugs are pushed. When using a drug push speed controller, the drug is first injected into the syringe, and then the pushing speed setting is adjusted to control the drug to be slowly pushed out of the syringe, thereby ensuring that the drug is pushed at a stable speed within a specific time, which helps to reduce drug waste and improve treatment effects.

[0003] At present, conventional medicine pushing speed controllers are used in a manual pushing manner. Although the amount of medicine pushed each time can be kept consistent, it is not convenient to control the interval time of each medicine pushing to be consistent. In addition, continuous pushing of medicine by holding the handle tightly can easily cause soreness in the hands of medical staff, making it inconvenient to use.

[0004] In view of the above problems, the utility model document proposes a timed automatic medicine pushing speed controller. Utility Model Content

[0005] The utility model provides a timed automatic medicine pushing speed controller, which solves the problem that the conventional medicine pushing speed controller in the prior art adopts a manual pushing method when in use. Although it can keep the medicine pushing amount consistent each time, it is inconvenient to control the medicine pushing interval to be consistent each time, and continuously pushing medicine by holding the handle tightly can easily cause soreness symptoms in the hands of medical staff, which is inconvenient to use.

[0006] The utility model provides the following technical solutions:

[0007] A timed automatic medicine pushing speed controller, comprising:

[0008] An L-shaped shell, a medicine-pushing cartridge is fixedly arranged at the bottom of the inner wall of the L-shaped shell, a matching piston is slidably connected in the medicine-pushing cartridge, an output tube is connected to the end of the medicine-pushing cartridge, and the other end of the output tube penetrates the outer wall of the L-shaped shell and extends out of the through-hole;

[0009] A liquid storage tank is fixedly arranged at the sunken part of the L-shaped shell, and the liquid storage tank is connected to the drug pushing cylinder through a drug extraction tube, and a cross-cut hard film is fixedly arranged at the tube opening of the drug extraction tube located in the drug pushing cylinder;

[0010] A medicine pushing component is arranged in an L-shaped shell and is used for intermittently pushing medicine liquid. The medicine pushing component includes a U-shaped frame fixedly arranged at the bottom of the inner wall of the L-shaped shell, a rack is slidably connected in the U-shaped frame, one end of the rack is fixedly connected to one side of the piston, an L-shaped mounting frame is fixedly arranged on the inner wall of the L-shaped shell, a micro motor is fixedly installed on the L-shaped mounting frame, an output shaft of the micro motor passes through the outer wall of the L-shaped mounting frame and is fixedly arranged with an intermittent gear, and the intermittent gear is meshed with the rack.

[0011] In a possible design, a limit block is fixedly provided at the bottom of the inner wall of the L-shaped housing, a telescopic sleeve and a spring are fixedly provided between the limit block and the other end of the rack, and the spring is sleeved on the telescopic sleeve.

[0012] In a possible design, sliding bars are fixedly provided on both sides of the rack, and sliding grooves for clamping corresponding sliding bars are provided on the inner wall of the U-shaped frame.

[0013] In a possible design, a sealing plug is provided at the liquid filling port on the top of the liquid storage tank.

[0014] In a possible design, the L-shaped housing is provided with a plurality of heat dissipation holes in a rectangular array for dissipating heat from the micro motor.

[0015] In a possible design, a handle is fixedly provided at the bottom of the outer wall of the L-shaped housing, and a battery block for powering the micro motor is arranged inside the handle.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] In the present application, when in use, a micro motor is used to drive the intermittent gear to rotate, thereby driving the piston into the push cartridge through the rack, and pushing the liquid medicine out from the outlet of the output tube;

[0018] When the intermittent gear rotates until it no longer meshes with the rack, the stretched spring generates a contraction traction force, prompting the rack to drive the piston to reset. During the piston reset process, negative pressure is generated in the medicine pushing cartridge, prompting the cross-cut hard film membrane to deform into the medicine pushing cartridge and causing the cross-cut to open and expand, thereby allowing the medicine in the liquid storage tank to enter the medicine pushing cartridge through the medicine extraction tube. When the intermittent gear and the rack mesh again, the rack drives the piston to push into the medicine pushing cartridge again. At this time, positive pressure is generated in the medicine pushing cartridge, prompting the cross-cut hard film membrane to reset and close the cross-cut, so that the medicine in the liquid storage tank will not continue to enter the medicine pushing cartridge, and the medicine in the medicine pushing cartridge will be pushed out again from the outlet of the output tube, and this reciprocating cycle is used to achieve an intermittent and regular medicine pushing frequency.

[0019] The utility model has the following beneficial effects:

[0020] The utility model can quantitatively extract the medicine liquid in the liquid storage tank and realize intermittent and regular medicine pushing frequency, so as to control the medicine pushing interval time to be consistent each time, without manual pushing, thereby avoiding the soreness symptoms in the hands of medical staff caused by continuously pushing the medicine by holding the handle tightly, and is more convenient to use.

[0028] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0029] Embodiment 1

[0030] Please refer to Figure 1-4 , a timed automatic medicine pushing speed controller, which is used in the field of medicine pushing speed controller, including:

[0031] An L-shaped housing 1, a medicine-pushing cartridge 2 is fixedly arranged at the bottom of the inner wall of the L-shaped housing 1, a matching piston 12 is slidably connected in the medicine-pushing cartridge 2, an output pipe 3 is connected to the end of the medicine-pushing cartridge 2, and the other end of the output pipe 3 penetrates the outer wall of the L-shaped housing 1 and extends out of the through-opening;

[0032] A liquid storage tank 4 is fixedly arranged at the sunken part of the L-shaped shell 1, and a sealing plug 5 is arranged at the liquid filling port on the top of the liquid storage tank 4. The liquid storage tank 4 is connected to the medicine pushing barrel 2 through a medicine extraction tube 6. A cross-cut hard film 7 is fixedly arranged at the tube mouth of the medicine extraction tube 6 located in the medicine pushing barrel 2. During the resetting process of the piston 12, a negative pressure is generated in the medicine pushing barrel 2, which prompts the cross-cut hard film 7 to deform into the medicine pushing barrel 2 and makes the cross-cut open and expand, so that the medicine in the liquid storage tank 4 enters the medicine pushing barrel 2 through the medicine extraction tube 6. When the intermittent gear 15 and the rack 9 are meshed again, the rack 9 drives the piston 12 to push into the medicine pushing barrel 2 again. At this time, a positive pressure is generated in the medicine pushing barrel 2, which prompts the cross-cut hard film 7 to reset and close the cross-cut, so that the medicine in the liquid storage tank 4 will not continue to enter the medicine pushing barrel 2, thereby achieving the effect of quantitatively extracting the medicine.

[0033] The medicine pushing component is arranged in the L-shaped shell 1 and is used for intermittently pushing the medicine liquid. The medicine pushing component includes a U-shaped frame 8 fixedly arranged at the bottom of the inner wall of the L-shaped shell 1. A rack 9 is slidably connected in the U-shaped frame 8. Slide bars 10 are fixedly arranged on both sides of the rack 9. A slide groove 11 for clamping the corresponding slide bar 10 is arranged on the inner wall of the U-shaped frame 8. When the rack 9 slides in the U-shaped frame 8, the slide bar 10 slides synchronously in the slide groove 11, which not only improves the stability of the rack 9 when sliding, but also can prevent the rack 9 from falling off. The U-shaped frame 8 is separated from the U-shaped frame 8, thereby limiting the position of the rack 9, one end of the rack 9 is fixedly connected to one side of the piston 12, an L-shaped mounting frame 13 is fixedly arranged on the inner wall of the L-shaped housing 1, a micro motor 14 is fixedly arranged on the L-shaped mounting frame 13, the output shaft of the micro motor 14 passes through the outer wall of the L-shaped mounting frame 13 and is fixedly arranged with an intermittent gear 15, the intermittent gear 15 is meshed with the rack 9, and the intermittent gear 15 is driven by the micro motor 14 to intermittently mesh with the rack 9, thereby achieving a regular medicine pushing frequency;

[0034] A limit block 17 is fixedly arranged at the bottom of the inner wall of the L-shaped housing 1, and a telescopic sleeve 18 and a spring 19 are fixedly arranged between the limit block 17 and the other end of the rack 9. When the intermittent gear 15 rotates to no longer mesh with the rack 9, the extended spring 19 generates a contraction traction force, prompting the rack 9 to drive the piston 12 to reset. The spring 19 is sleeved on the telescopic sleeve 18, and the setting of the telescopic sleeve 18 ensures the stability of the spring 19 during the extension and contraction process;

[0035] More specifically, in this embodiment, when in use, the micro motor 14 is used to drive the intermittent gear 15 to rotate, thereby driving the piston 12 to push into the push cartridge 2 through the rack 9, and pushing the liquid medicine out of the outlet tube 3. When the intermittent gear 15 rotates to no longer mesh with the rack 9, the extended spring 19 generates a contraction traction force, prompting the rack 9 to drive the piston 12 to reset. During the reset process of the piston 12, negative pressure is generated in the push cartridge 2, prompting the cross-cut hard film 7 to deform into the push cartridge 2 and cause the cross-cut to open and expand, so that the liquid medicine in the liquid storage tank 4 can be discharged through the drug extraction tube. 6 enters the medicine pushing barrel 2, and when the intermittent gear 15 and the rack 9 are meshed again, the rack 9 drives the piston 12 to push into the medicine pushing barrel 2 again. At this time, positive pressure is generated in the medicine pushing barrel 2, prompting the cross-cut hard film 7 to reset and close the cross-cut, so that the medicine liquid in the liquid storage tank 4 will not continue to enter the medicine pushing barrel 2, and the medicine liquid in the medicine pushing barrel 2 is pushed out again from the mouth of the output tube 3, and this reciprocating process is used to achieve an intermittent and regular medicine pushing frequency, and there is no need to push manually, thereby avoiding the soreness of the hands of medical staff caused by continuous pushing of medicine by holding the handle tightly, and it is more convenient to use.
