Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a device for cleaning and drying injection ampoules. Background Art

[0002] Ampoules are small glass containers for holding liquid medicine, with a capacity of generally 1 to 25 ml. They are commonly used to store injectable drugs, vaccines, sera, etc. They are widely used to hold injectable preparations and high-purity chemicals that must be isolated from the air. The bottle mouth is sealed with an open flame to isolate the air, and the neck of the bottle is marked. When pressure is applied, the neck of the bottle will break to extract the liquid medicine. The ampoule must be rinsed with pure water before use to ensure that the ampoule is clean. Therefore, cleaning glass ampoules is an important task for pharmaceutical manufacturers. Currently, ultrasonic bottle washing machines are usually used to clean ampoules with pure water. However, the equipment structure used to prepare pure water for cleaning ampoules in traditional technologies is relatively complex and inconvenient to use, resulting in low work efficiency.

[0003] After searching, the Chinese patent (publication number: CN214022492U) disclosed "a small-volume injection ampoule cleaning and drying device, comprising a clamping mechanism and a lifting mechanism, wherein the top of the clamping mechanism is fixedly connected to the lifting mechanism, the clamping mechanism comprises a clamping ring and a suction cup, the interior of the clamping ring is provided with an inner cavity, the inner cavity is provided with two through grooves, the inner wall of the inner cavity is slidably interspersed with two symmetrical push rods, and the two push rods are respectively located in the two through grooves, and the opposite surfaces of the two push rods are fixedly connected to suction cups, which are elastic, It can firmly absorb smooth curved surfaces. The top of the clamping ring is fixedly connected to a lifting mechanism; the lifting mechanism includes a cylinder and a brush. Two cylinders are provided, and their bottoms are respectively fixedly connected to the two sides of the top surface of the clamping ring.

The motor controls the heating and rotation of the heating rod to enable the brush to clean.

[0004] However, in the process of implementing relevant technologies, this type of patent has certain technical defects: First, this patent uses a brush to directly contact the inner wall of the bottle, which causes great friction between the brush and the inner wall of the bottle, which can easily cause scratches on the inner wall of the bottle. Moreover, after the brush cleans the stains, it cannot ensure that the residual particles on the bristles are removed, which can easily cause cross-contamination during the next cleaning.

[0005] Second, the heating rod of this patent relies solely on contact heat transfer and cannot achieve the uniform high temperature required for sterilizing ampoules. Moreover, due to insufficient temperature, the drying time is long, which greatly reduces the drying efficiency.

[0026] During cleaning, the ampoule is placed inside the holder 2, and then the ampoule is fixed by the positioning mechanism 4. Then, the two cylinders 5 are controlled to drive the mounting plate 6 downward, so that the rotating drum 72 is inserted into the ampoule from the bottle mouth of the ampoule, so that the silicone strip 73 contacts the inner wall of the ampoule. By starting the driving member 74 to drive the hollow shaft 71 to rotate, the rotating drum 72 drives the silicone strip 73 to rotate circumferentially and clean the inner wall of the ampoule.

[0027] Furthermore, the positioning mechanism 4 includes two sliders 41 distributed along the center line of the card seat 2. The two sliders 41 are slidably connected to the sliders 41 inside the two side seats 3 respectively. One side of the two sliders 41 is fixedly connected to a connecting rod 43.

The joint 45 includes two screw rods 451, the screw threads of the two screw rods 451 are in opposite directions, and the two screw rods 451 are distributed along the center line of the card base 2. The two screw rods 451 are respectively rotatably connected to the bottom of the two side seats 3, the screw threads of the two screw rods 451 are in opposite directions, and the two screw rods 451 are distributed along the center line of the card base 2.

[0028] By starting the motor 1 453 to drive the bevel gear 2 454 to rotate, the two bevel gears 1 452 rotate synchronously in the same direction, and the two screw rods 451 rotate synchronously. Since the screw threads of the two screw rods 451 are in opposite directions, the two sliders 41 can rotate towards or away from each other. When the two sliders 41 move towards each other, the two connecting rods 43 will drive the two suction cups 44 to move towards each other and clamp the ampoule bottle, thereby fixing the ampoule bottle and keeping the ampoule bottle stable during the cleaning process.

[0029] Furthermore, the driving member 74 includes a spur gear 1 741 fixedly connected to the top of the hollow shaft 71, one end of the top of the mounting plate 6 is fixedly connected to a fixing bracket 742, a motor 2 743 is fixedly installed on the top of the fixing bracket 742, and the output shaft of the motor 2 743 is fixedly connected to a spur gear 2 744, which is engaged with the spur gear 1 741.

[0030] By starting motor 2 743 to drive spur gear 2 744 to rotate, spur gear 1 741 drives hollow shaft 71 to rotate synchronously, so that rotating drum 72 drives silicone strip 73 to rotate circumferentially and clean the inner wall of ampoule bottle. At the same time, negative pressure component 79 guides the water inside water tank 78 into connecting pipe 77, and then continues to guide it into the hollow shaft 71 through pipe joint 76, and then guides it into the rotating drum 72 and outputs it through leakage hole 721. In conjunction with the circumferential movement of silicone strip 73, the inner wall of ampoule bottle can be dynamically washed with water.

[0031] Furthermore, the negative pressure assembly 79 includes a cylinder 791 fixedly connected to the top of the mounting plate 6, one end of the cylinder 791 is slidably connected to a slide rod 792 that passes through the side wall of the cylinder 791, one end of the slide rod 792 is fixedly connected to a piston 793, the piston 793 is slidably connected to the inner wall of the cylinder 791, and the other end of the slide rod 792 is provided with a linkage part 798 that drives the slide rod 792 to slide back and forth by cooperating with the rotation of the hollow shaft 71, the inlet end of the cylinder 791 is fixedly connected to a water inlet one-way valve 795, the inlet end of the water inlet one-way valve 795 is fixedly connected to a water inlet hose 794, the inlet end of the water inlet hose 794 is connected to the inside of the water tank 78, the outlet end of the cylinder 791 is fixedly connected to a water outlet one-way valve 797, the outlet end of the water outlet one-way valve 797 is fixedly connected to a water outlet pipe 796, and the outlet end of the water outlet pipe 796 is connected to the inside of the connecting pipe 77.

[0032] The linkage member 798 includes a mounting seat 7981 fixedly connected to the end of the slide rod 792, the inner side of the mounting seat 7981 is rotatably connected to a pressure wheel 7982, the outer side of the hollow shaft 71 is fixedly connected to a cam 7983, the cam 7983 intermittently conflicts with the pressure wheel 7982 by cooperating with the rotation of the hollow shaft 71, and the outer side of the slide rod 792 is provided with a return spring 7984, one end of the return spring 7984 conflicts with the cylinder 791, and the other end of the return spring 7984 conflicts with the mounting seat 7981.

[0033] By starting the second motor 743 to drive the second spur gear 744 to rotate, the first spur gear 741 drives the hollow shaft 71 to rotate synchronously, so that the rotating drum 72 drives the silicone strip 73 to rotate circumferentially and clean the inner wall of the ampoule bottle. At the same time, the hollow shaft 71 drives the cam 7983 to rotate synchronously. When the cam 7983 contacts the pressure wheel 7982, the pressure wheel 7982 is squeezed and drives the slide bar 792 to slide. At this time, the return spring 7984 is compressed and accumulates potential energy. When the cam 7983 is separated from the pressure wheel 7982, the potential energy of the return spring 7984 causes the slide bar 792 to slide in the opposite direction. This cycle repeats, and the slide bar 792 slides back and forth, causing the piston 793 to slide back and forth inside the cylinder 791, thereby causing the pressure inside the cylinder 791 to intermittently increase and the gap. When the internal pressure of the cylinder 791 decreases, the water inlet hose 794 will guide the water in the water tank 78 into the cylinder 791. When the internal pressure of the cylinder 791 increases, the water outlet pipe 796 will guide the water in the cylinder 791 into the connecting pipe 77. This cycle will continue. The water outlet pipe 796 can intermittently guide water into the connecting pipe 77, and then continue to guide it into the hollow shaft 71 through the pipe joint 76, and then guide it into the rotating drum 72 and out through the leakage hole 721. In conjunction with the circumferential movement of the silicone strip 73, the inner wall of the ampoule bottle can be dynamically washed with water, which greatly improves the cleaning effect of the ampoule bottle.

[0034] Furthermore, the drying mechanism 8 includes a hot air blower 81 fixedly connected to the top of the mounting plate 6, the outlet end of the hot air blower 81 is fixedly connected to an air duct 82, the outlet end of the air duct 82 is connected to the inside of the connecting pipe 77, and a control valve 83 is fixedly connected to the air duct 82.

[0035] After cleaning is completed, the ampoule is taken out and the water inside is poured out, and then it is fixed again by the positioning mechanism 4, and then the two cylinders 5 are controlled to drive the mounting plate 6 to move downward, so that the rotating drum 72 is inserted into the ampoule from the bottle mouth of the ampoule, and then the hot air blower 81 is started and the control valve 83 is opened, so that the air guide pipe 82 guides the hot air into the connecting pipe 77, and then into the hollow shaft 71 through the pipe joint 76, and then into the rotating drum 72 and the hot air is evenly discharged through the water leakage hole 721. The hot air temperature is high, so that the internal temperature of the ampoule rises rapidly, thereby achieving sterilization and drying effects.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
