Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a reusable ampoule opening device. Background Art

[0002] An ampoule is a small glass container used to hold liquid medicine. Its capacity typically ranges from 1 to 25 ml. It's commonly used to store injectable medications and is also used to package oral solutions. Doctors first grind the top of the ampoule with a grinding wheel, then forcefully break it off or directly smash it with a metal hammer. The existing operation has the following disadvantages: (1) Medical staff can easily scratch their hands by breaking off the head of the ampoule directly with their hands, causing infection. Moreover, if the amplitude is too large when breaking off the head of the ampoule, the liquid medicine in the ampoule will often splash out and be contaminated to a certain extent. (2) When using metal to smash the head of the ampoule, some glass fragments or powder will often fall into the liquid medicine, causing liquid medicine contamination. If the ampoule is smashed with too much force, the entire ampoule will shatter, which is more likely to cause scratches on the hands of medical staff. (3) When opening a standard ampoule, the opening of the ampoule must be disinfected. Only after disinfection can the head of the ampoule be polished with a grinding wheel. However, the efficiency of disinfection with cotton balls or disinfection sticks is particularly slow. When different ampoules need to be opened, a lot of time is often wasted on disinfection work.

[0021] In order to further understand the purpose, structure, features, and functions of the present invention, the following detailed description is given with reference to the following embodiments. Figure 1 As shown, a reusable ampoule opening device includes a first sleeve 100, a second sleeve 200 and a breaking device 300. The second sleeve 200 is sleeved on the outside of the first sleeve 100, and the first sleeve 100 and the second sleeve 200 are slidably matched. The breaking device 300 includes a first end 310 and a second end 320. The breaking device 300 passes through the side walls of the first sleeve 100 and the second sleeve 200. The first end 310 is located in the inner cavity of the first sleeve 100, and the second end 320 is on the outside of the second sleeve 200. A disinfection device 110 and a scratching device 120 are respectively provided on the left and right sides of the first sleeve 100.

[0022] In one embodiment, if Figure 1 As shown, the first sleeve 100 includes an upper end 130 and a lower end 140. The upper end 130 is a closed end, and the lower end 140 has an annular groove 141 for the ampoule to be inserted into. When the ampoule mouth is opened, the ampoule is inserted into the annular groove 141 to prevent the ampoule from tipping over and causing liquid splashing or leakage.

[0023] In one embodiment, if Figure 1As shown, the scratching device 120 includes a plug pin 121 and a cutter 122 fixed to one end of the plug pin. The plug pin 121 passes through the cavity wall of the first sleeve 100. A first spring 123 is sleeved on the plug pin 121. A spring fixing block is provided on the side wall of the plug pin. One end of the first spring 123 is fixed to the side wall of the inner cavity of the first sleeve 100, and the other end of the first spring 123 is fixed to the plug pin 121. The cutter 122 is located in the inner cavity of the first sleeve 100, and the plug end of the plug pin 121 is located outside the first sleeve. The cutter 122 is made of diamond. During use, the plug pin 121 can be squeezed inward by hand, and the cutting knife will be forced to move toward the inner cavity of the first sleeve 100, and the first spring 123 will extend and hit the side wall of the bottleneck of the ampoule bottle, so that the cutting knife 122 can scratch the bottleneck and open the bottle mouth of the ampoule bottle, simplifying the step of grinding the bottle mouth with a grinding wheel in the prior art. After the marking is completed, the plug pin is no longer under force, and the first spring contracts and returns to its original shape, so that the cutting knife is away from the bottleneck of the ampoule bottle.

[0024] In one embodiment, if Figure 1 As shown, a disinfection device 110 is provided at the same height of the scratching device. The disinfection device includes a first plug pin 111, a second spring 112 and a disinfection cotton swab 113. The first plug pin 111 passes through the cavity wall of the first sleeve 100. Figure 2 As shown, the upper portion of the first plug pin 111 has a cotton swab groove 111 (1), and the sterile cotton swab 113 is placed in the cotton swab groove 111 (1). Figure 1 As shown, the sterilizing cotton of the sterilizing cotton swab 113 faces the inner side of the first sleeve 100, the second spring 112 is sleeved on the first plug pin 111, and a second spring fixing block is provided on the side wall of the first plug pin 111. One end of the second spring 112 is fixed to the side wall of the inner cavity of the first sleeve 100, and the other end of the second spring 112 is fixed to the first plug pin. In addition to allowing the sterilizing cotton swab to move inward to contact the bottleneck of the ampoule and disinfect it, this arrangement also allows the first plug pin 111 to be pulled outward to replace the sterilizing cotton swab 113 in the cotton swab groove, making the present invention reusable multiple times without being limited by the number of sterilization times.

[0025] In one embodiment, if Figure 1As shown, the upper and lower ends of the second sleeve 200 are open. The lower end of the second sleeve 200 corresponds to the plug pin 121 and the first plug pin 111. The thickness of the sidewall of the inner cavity of the lower end of the second sleeve 200 gradually decreases from top to bottom. When the second sleeve 200 slides downward, it can contact the plug pin and the first plug pin, causing them to move into the inner cavity of the first sleeve 100 and contact the bottleneck of the ampoule. This avoids using the palm force to push the plug pin and the first plug pin inward, which would require constant contact there and cause fatigue to the medical staff's palms.

[0026] In one embodiment, if Figure 1 As shown, a cotton swab removing device 150 is provided on the outer side wall of the first sleeve 100 , and the cotton swab removing device 150 is fixed above the first plug pin 111 .

[0027] like Figure 3 As shown, the cotton swab cleaning device 150 includes a storage box 151 and a toggle plate 152. The storage box 151 is fixed on the outer wall of the first sleeve. A first strip hole 151 (1) is provided on the side wall of the storage box 151. The toggle plate 152 is placed inside the storage box 151. A push block 152 (1) is provided on the side of the toggle plate 152. The push block 152 (1) is exposed from the first strip hole 151 (1). The lower end of the toggle plate 152 is exposed from the storage box 151. The toggle plate 152 can slide up and down. When in use, the toggle plate can be inserted into the cotton swab groove. The toggle plate conflicts with the non-sterile end of the sterile cotton swab. When the first plug pin is pulled outward by hand, the sterile cotton swab can fall off from the cotton swab groove, making the cotton swab cleaning more simple and quick, saving cotton swab replacement time.

[0028] In one embodiment, if Figure 4 As shown, the breaking device 300 includes a first push block 330, a second push block 340, a first spring 350 and a connecting rod 360. The two ends of the connecting rod 360 are respectively fixedly connected to the first push block 330 and the second push block 340. The first spring 350 is sleeved on the connecting rod 360. Figure 1 As shown, one end of the first spring 350 is fixed on the outer wall of the second sleeve 200, and the other end of the first spring 350 is fixed on the second push block 340. The first push block 330 is located in the inner cavity of the first sleeve 100, and the connecting rod 360 passes through the side walls of the first sleeve 100 and the second sleeve 200. The second push block 340 is located on the outside of the second sleeve 200.

[0029] like Figure 1As shown, the side wall of the first sleeve 100 is provided with a strip-shaped hole 160, through which the connecting rod 360 passes. This allows the second sleeve 200 of the present invention to slide on the first sleeve 100 but not to separate from the first sleeve 100, causing separation of the first and second sleeves 100, or damage to the device if one of the sleeves is lost. The sliding range corresponds to the length of the strip-shaped hole 160. When the first spring 350 is not deformed, the length of the connecting rod 360 between the outer wall of the second sleeve 200 and the second push block 340 is equal to the radius of the inner cavity of the first sleeve 100. The length of the connecting rod outside the outer wall of the second sleeve is limited. When the connecting rod 360 is pushed into the inner cavity of the first sleeve, it can only be pushed to the position of the central axis of the first sleeve and cannot continue to be pushed inward. This prevents the situation where the thrust is too large when the length is not limited, and the connecting rod is pushed inward for a long length, causing the upper part of the ampoule bottle to collide with the inner cavity of the first sleeve 100 and break, and glass fragments or powder fall into the medicine liquid and contaminate the medicine liquid.

[0030] In one embodiment, if Figure 4 As shown, the side of the first push block 330 away from the second push block 340 has a semicircular groove 331, with a rubber pad disposed within the groove 331. The semicircular groove 331 prevents the neck of the ampoule from coming loose from the side of the first push block during use, thereby preventing the ampoule from being opened. Furthermore, the rubber pad disposed within the groove 331 ensures a non-rigid contact between the first push block and the neck of the ampoule, preventing the neck of the ampoule from breaking and glass fragments or powder from falling into the liquid medicine and contaminating it.

[0031] How to use: Figure 5 As shown, first, the bottleneck of the ampoule bottle is inserted into the inner cavity of the first sleeve 100, and the upper part of the bottle body of the ampoule bottle is embedded in the annular groove 141. Then, the second sleeve 200 is slid downward, and the inner wall of the second sleeve 200 can abut the plug pin 121 and the first plug pin 111, so that they both move toward the inner cavity of the first sleeve 100 and abut against the bottleneck of the ampoule bottle; then, the first sleeve 100 is rotated at least one circle to scratch and disinfect the bottleneck of the ampoule bottle; then, the second push block 340 is pushed toward the inner side of the first sleeve 100, so that the breaking device 300 moves inward as a whole, abuts the bottleneck of the ampoule bottle and breaks the bottleneck; finally, the bottle body of the ampoule bottle is removed, as shown in FIG. Figure 6As shown, the second sleeve 200 is slid upward so that the scratching device 120 and the disinfection device 110 return to their original positions, and the toggle piece 152 is slid down so that the toggle piece can enter the cotton swab groove. The toggle piece conflicts with the non-sterile end of the disinfected cotton swab, and the first connecting pin 111 is pulled outward by hand. The disinfected cotton swab 113 and the broken head of the ampoule can be removed from the first sleeve 100. The toggle piece 152 is slid upward and a new disinfected cotton swab is placed in the cotton swab groove. Stop pulling the first connecting pin 111. The first connecting pin is restored to its original position under the influence of the recovery deformation of the second spring 112, completing the replacement of the disinfected cotton swab and providing preliminary preparations for opening the ampoule next time.

[0032] The present invention has been described with reference to the above embodiments. However, the above embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements that do not depart from the spirit and scope of the present invention are intended to be protected by the present invention.
