Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and particularly to an oil-based drug dispensing device. Background Art

[0002] Cod liver oil is widely used for nutritional supplementation due to its rich content of vitamin A / D. However, the swallowing function of newborns is not fully developed, and it is easy for granular cod liver oil capsules to adhere to the esophageal wall when fed, posing a risk of choking. Therefore, in the traditional method, medical staff need to puncture and aspirate granular cod liver oil capsules with a syringe, and then feed them through a dropper or a syringe. There are significant defects in the existing aspiration operation: First, when puncturing the capsule, the needle tip needs to be fixed by hand. Since the surface of the capsule is smooth and newborns are prone to movement, the needle is extremely easy to slip off and stab the operator's finger, causing the risk of occupational exposure. Second, at the moment when the needle penetrates the capsule, the cod liver oil will be squeezed and leak from the gap between the syringe barrel and the puncture hole of the capsule, not only polluting the operation environment, but also resulting in waste of some cod liver oil. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an oil-based drug dispensing device that does not require manual fixation for extraction and can reduce the waste of active ingredients.

The upper end surface of the fixing frame is provided with a placement groove for placing the oil-based drug. The placement groove corresponds to the pressing columns up and down, and the pressing columns can move into the placement groove and be hermetically connected to it; a jack communicating with the placement groove is arranged on the fixing frame; the mounting frame is arranged on the base for installing the syringe and setting it below the jack, and the liquid suction tube of the syringe is inserted into the jack; the lifting platform is arranged in the base, and its lifting end extends out of the surface of the base and is located below the mounting frame, and its lifting end is used to abut against the lower end of the mounting frame.

[0006] In some embodiments, the pressing-down component includes a fixing plate, a handle, a pressing-down rod, and a connecting piece; a first kidney-shaped hole is provided on the plate surface of the mounting plate, and the fixing plate is installed in the first kidney-shaped hole on the mounting plate by cooperating with bolts and nuts; fixing blocks extend outwards respectively from the upper end and the lower end of the plate surface of the fixing plate, and a sleeve is provided on the fixing block located below; the handle is in an "L" shape, its horizontal part is for grasping, and the end of its vertical part faces downwards and is hinged to the fixing block located above the fixing plate; the pressing-down rod is slidably arranged in the sleeve, and the lower end of the pressing-down rod is connected to the upper plate surface of the pressing plate; there are two connecting pieces, which are respectively arranged on both sides of the handle, one end of the connecting piece is hinged to the connection part of the horizontal part and the vertical part of the handle, and the other end is hinged to the upper end of the pressing-down rod; flipping the handle upwards can drive the pressing-down rod to move downwards.

[0007] In at least one embodiment, the oil-based drug dispensing device further includes a sliding rod and a sliding plate. There are two sliding rods, which are erected on the upper surface of the base and are located on both sides of the front end surface of the mounting plate; a limiting hole through which the pressing-down rod can pass is communicated with the bottom in the middle area of the upper surface of the sliding plate, through holes are respectively communicated with the upper and lower surfaces at both ends of the sliding plate, and a linear bearing is fixedly installed in each through hole, and the sliding plate is slidably arranged on the sliding rod through the linear bearing.

[0008] In at least one embodiment, the fixing frame is in an "n" shape and is installed on the base with its opening facing downwards; the placing groove is arranged on the upper surface of the fixing frame, and puncture needles for puncturing oil-based drugs are evenly distributed in the placing groove; a puncture hole is arranged on the bottom surface of the extrusion column to cooperate with the puncture needles in the placing groove.

[0021] The present invention will be described in detail below with reference to the exemplary embodiments in the drawings. It should be understood, however, that the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present invention more complete and to fully convey the concept of the present invention to those skilled in the art.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "transverse", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as limiting the protection scope of the present invention.

[0023] As Figures 1 to 7 shown, in the oil-based drug dispensing device of the present invention, it includes a syringe 1, a base 2, a mounting plate 3, a pressing-down assembly 4, a pressing plate 5, a fixing bracket 6, a mounting bracket 7, and a lifting platform 8.

[0024] The syringe 1 includes a syringe 100, a piston 110 movably arranged in the syringe 100, a push rod 120 connected to the piston 110, a push handle 1201 arranged at the end of the push rod 120, a liquid extraction tube 1001 connected to the front end of the syringe 100, and needle wings 1002 arranged on both sides of the end of the syringe 100. The mounting plate 3 is vertically arranged on the base 2. The pressing assembly 4 is mounted on the upper end of the mounting plate 3. The pressing assembly 4 has a telescopic end that can be telescopic up and down, and the squeezing plate 5 is arranged at the lower end of the telescopic end and can move up and down with the telescopic end. The lower plate surface of the squeezing plate 5 is provided with a squeezing column 51. The fixing frame 6 is installed on the base 2 and is located below the squeezing plate 5. The upper end surface of the fixing frame 6 is provided with a placement groove 61 for placing oily drugs. The placement groove 61 corresponds to the squeezing column 51 up and down, and the squeezing column 51 can move into the placement groove 61 and be sealed with it. The fixing frame 6 is provided with a jack 62 connected to the placement groove 61. The mounting frame 7 is arranged on the base 2, and is used to install the syringe 1 and is arranged below the jack 62, so that the liquid extraction tube 1001 of the syringe 1 is inserted into the jack 62. The lifting platform 8 is arranged in the base 2, and its lifting end extends out of the surface of the base 2 and is located below the mounting frame 7, and its lifting end is used to resist the lower end of the mounting frame 7. In this embodiment, the oil medicine is a capsule pill with fish oil, and the placement groove 61 is cylindrical, and its inner diameter is equal to the outer diameter of the extrusion column 51, so that the liquid can be prevented from splashing out when the oil medicine is squeezed. In order to facilitate the extrusion column 51 to be smoothly inserted into the placement groove 61, the notch edge of the placement groove 61 is chamfered.

[0025] In this embodiment, the placement groove 61 and the squeezing column 51 are precisely matched to form a closed squeezing space, which directly solves the problem of drug leakage. At the same time, the drug is squeezed through the pressing component 4, eliminating the defect that the operator needs to fix the drug by hand to extract the liquid.

[0026] refer to Figure 2, specifically, the pressing component 4 includes a fixing plate 41, a handle 42, a pressing rod 43 and a connecting piece 44. A first waist-shaped hole 31 is provided on the plate surface of the mounting plate 3. The fixing plate 41 is installed in the first waist-shaped hole 31 on the mounting plate 3 by means of bolts and nuts. By setting it in this way, the position of the fixing plate 41 can be adjusted up and down. Fixed blocks 411 extend outward from the upper and lower ends of the plate surface of the fixing plate 41 respectively, and a sleeve 412 is provided on the fixed block 411 located below. The handle 42 is in an "L" shape, the horizontal part of which is for grasping, and the end of the vertical part faces downward and is hinged to the upper fixed block 411 of the fixing plate 41. The pressing rod 43 is slidably arranged in the sleeve 412, and the lower end of the pressing rod 43 is connected to the upper plate surface of the pressing plate 5. There are two connecting pieces 44, which are respectively arranged on both sides of the handle 42. One end of the connecting piece 44 is hinged to the connection part of the horizontal part and the vertical part of the handle 42, and the other end is hinged to the upper end of the pressing rod 43. Flipping the handle 42 upward can drive the pressing rod 43 to move downward. Through the lever structure setting of the L-shaped handle 42 and the connecting piece 44, the manual flipping can be converted into a vertical downward pressure, which is more labor-saving in operation and effectively avoids the hand approaching the needle; at the same time, the sleeve 412 guides the pressing rod 43 to ensure the vertical movement of the pressing column 51, prevent puncture deviation, and thus ensure the sealing performance.

[0027] In order to ensure the verticality of the downward pressing of the pressing column 51, the oil-based drug dispensing device further includes a sliding rod 9 and a sliding plate 10. There are two sliding rods 9, which are erected on the upper surface of the base 2 and are located on both sides of the front end surface of the mounting plate 3. In this embodiment, connecting plates 32 are provided on both sides of the front end surface of the upper end of the mounting plate 3. The connecting plates 32 are located directly above the sliding rods 9 and are fixedly connected to the sliding rods 9 to fix the sliding rods 9 and prevent them from shaking. A limiting hole 101 through which the pressing rod 43 can pass is provided in the middle area of the upper surface of the sliding plate 10 and communicates with the bottom. In this embodiment, the diameter of the limiting hole 101 is the same as the diameter of the pressing rod 43. Through holes 102 are respectively provided on the upper and lower surfaces of both ends of the sliding plate 10 in a communicating manner, and a linear bearing 11 is fixedly installed in each through hole 102. The sliding plate 10 is slidably arranged on the sliding rod 9 through the linear bearing 11. By setting it in this way, it can be ensured that the pressing column 51 on the lower plate surface of the pressing plate 5 can accurately insert into the placing groove 61 when moving downward; at the same time, the sliding plate 10 is restricted to move only along the Z-axis, eliminating horizontal shaking and ensuring that the pressing column 51 accurately inserts into the placing groove 61. The setting of the limiting hole 101 can correct the downward pressing path twice, avoid the sealing failure caused by processing errors, and further consolidate the anti-leakage effect.

[0028] The fixing bracket 6 is in an "n" shape and is installed on the base 2 with its opening facing downward. A placement groove 61 is provided on the upper surface of the fixing bracket 6, and puncturing needles 611 for puncturing oily medicine are evenly distributed in the placement groove 61. A puncturing hole 511 is provided on the bottom surface of the extrusion column 51 corresponding to the puncturing needles 611 in the placement groove 61. The puncturing needles 611 puncture the capsules in advance, and when extruded, the liquid directly flows into the syringe 1 through the insertion hole 62. The puncturing hole 511 accommodates the tip of the puncturing needle 611 to prevent the needle tip from bending.

[0029] To facilitate the quick locking of the syringe 1, the mounting bracket 7 is in a square structure with a hollow middle, and a clamping groove 71 for clamping the barrel 100 of the syringe 1 is provided at its upper end, and insertion slots 711 for inserting the needle wings 1002 of the syringe 1 are provided on both sides of the clamping groove 71.

[0030] To facilitate the timely collection of the squeezed liquid medicine, the oily medicine dispensing device further includes a linkage rod 12. The linkage rod 12 is arranged between the fixing bracket 6 and the mounting plate 3, and its upper end is connected to the lower plate surface of the sliding plate 10. Specifically, it is fixedly connected by screws. The other end is provided with a clamping block 121, and the clamping block 121 is used for clamping the push rod 120 of the syringe 1 and blocking above the push handle 1201. By such a setting, the syringe 1 can be synchronously sucked while the pressing component 4 is pressed downward.

[0031] Reference Figure 7, specifically, the lifting platform 8 includes a bottom plate 81, a top plate 82, a scissor arm group 83, a first cross bar 84, a second cross bar 85, a nut 86, a lead screw 87 and a motor 88. The top plate 82 is arranged above the bottom plate 81, and the top plate 82 is the lifting end of the lifting platform 8. First sliding grooves 811 are arranged on both sides of the upper plate surface of the bottom plate 81, and second sliding grooves 821 are arranged on both sides of the lower plate surface of the top plate 82. Two groups of scissor arm groups 83 are arranged between the bottom plate 81 and the top plate 82. The two groups of scissor arm groups 83 are respectively located on both sides of the bottom plate 81, and each group of scissor arm groups 83 includes a first connecting rod 831 and a second connecting rod 832. The middle parts of the first connecting rod 831 and the second connecting rod 832 are hinged. The lower end of the first connecting rod 831 is hinged to the front end of the bottom plate 81, and the upper end of the second connecting rod 832 is hinged to the front end of the top plate 82. The upper ends of the first connecting rods 831 of the two groups of scissor arm groups 83 are respectively hinged to the rod body of the first cross bar 84. The two ends of the first cross bar 84 respectively penetrate into the second sliding grooves 821 on both sides of the top plate 82 and can move in the second sliding grooves 821. The lower ends of the second connecting rods 832 of the two groups of scissor arm groups 83 are respectively hinged to the rod body of the second cross bar 85. The two ends of the second cross bar 85 respectively penetrate into the first sliding grooves 811 on both sides of the bottom plate 81 and can move in the first sliding grooves 811. The nut 86 is installed in the middle of the second cross bar 85. One end of the lead screw 87 penetrates into the bottom plate 81 and is connected to the nut 86, and the other end is connected to the rotating shaft of the motor 88. The motor 88 is used to drive the lead screw 87 to rotate and drive the nut 86 and the second cross bar 85 to move along the first sliding groove 811. A control button 89 for controlling the rotation of the motor 88 is arranged on the surface of the base 2. In this embodiment, the lifting platform 8 further includes a controller 90 and a power supply 91. The controller 90 and the power supply 91 are arranged inside the base 2. The controller 90 receives instructions through the control button 89 and drives the motor 88 to rotate forward and backward to drive the top plate 82 to lift. The power supply 91 is used to provide the working voltage, and the motor 88 is a stepping motor. The control button 89 includes a switch button 891, a forward rotation button 892 for the motor 88 to rotate forward and a reverse rotation button 893 for the motor 88 to rotate backward. When the motor 88 rotates forward or backward, the scissor arm group 83 composed of the first connecting rod 831 and the second connecting rod 832 will tighten or expand, so that the top plate 82 arranged on the first connecting rod 831 and the second connecting rod 832 will rise or fall. By setting like this, it is ensured that after the liquid suction tube 1001 of the syringe 1 is inserted into the jack 62, the syringe 1 will not fall down due to gravity.

[0032] The usage method of the oil agent medicine dispensing device is as follows: When in use, first clip the syringe 1 into the card slot 71 and the insertion slot 711 of the mounting bracket 7, then lower the lifting platform 8, place the mounting bracket 7 with the syringe 1 installed on the lowered lifting platform 8, lift the lifting platform 8, hold the mounting bracket 7 by hand to align the liquid suction tube 1001 of the syringe 1 with the insertion hole 62, and lift the top plate 82 through the control button 89 of the lifting platform 8 to tightly insert the liquid suction tube 1001 into the insertion hole 62 of the fixing bracket 6; place the cod liver oil capsule in the placement groove 61; turn up the L-shaped handle 42, and through the connecting piece 44, the lever pushes the lower pressing rod 43 to vertically move downward along the sleeve 412, so that the extrusion column 51 breaks the cod liver oil capsule in the placement groove 61. Due to the setting of the linkage rod 12, when the lower pressing assembly 4 presses down, the syringe 1 also simultaneously performs a liquid suction action; finally, after releasing the handle 42, the extrusion column 51 rises, lower the lifting platform 8, then the mounting bracket 7 can be taken out, and the syringe 1 can be removed.

[0033] It should be understood that all of the above embodiments are exemplary rather than restrictive. Under the concept of the present invention, various modifications or deformations made by those skilled in the art to the specific embodiments described above should fall within the protection scope of the present invention.
