Description

Technical Field

[0001] The utility model relates to the field of needle-free syringe medicine dispensing devices, in particular to a novel single-syringe flexible medicine dispensing device. Background Art

[0002] The drug dispensing device of the needle-free syringe is an important component of the needle-free syringe, which is mainly responsible for the extraction and preparation of the drug solution. The needle-free syringe is a new type of transdermal drug delivery method. It can inject the drug solution into the subcutaneous tissue without the use of a needle, thereby reducing pain and skin damage. In the needle-free syringe, the drug dispensing device usually includes a drug solution container and an extraction mechanism. The drug solution container is used to store the drug solution, and the extraction mechanism is responsible for extracting the drug solution from the container in preparation for injection.

[0003] The inventor of this application found that there are the following problems in the practical use process:

[0004] The current insulin needle-free syringe dispensing device is mainly used to extract a fixed amount of insulin from the insulin bottle and inject it into an ampoule bottle for needle-free injection. However, there is a significant problem during operation: when the ampoule bottle is removed from the device, since there is still a large amount of insulin in the insulin bottle, most of the existing insulin infusion propulsion mechanisms use a threaded propulsion design, which has the risk of misoperation. Since this threaded propulsion mechanism itself has a certain degree of mobility, the user may accidentally touch or turn it during operation, thereby causing insulin leakage in the insulin bottle. This situation will not only cause waste of drugs, but may also cause drug contamination problems, posing potential safety risks to patients.

[0005] Therefore, it is necessary to provide a new single-piece flexible medicine dispensing device to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a novel single-piece flexible medicine taking device in view of the above-mentioned defects of the prior art.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a new type of single-piece flexible medicine dispensing device, including: a medicine dispensing component, an inner sleeve component, a medicine dispensing device, an ampoule bottle and an insulin medicine bottle, the medicine dispensing component includes an outer sleeve, a limiting mechanism is provided on one side of the outer sleeve, the limiting mechanism includes a fixed ring, the outer side of the fixed ring is threadedly connected to a rotating ring, the inner side of the fixed ring is provided with a spring sheet, and the outer side of the spring sheet and the inner side of the rotating ring are both formed with inclined surfaces.

[0008] By adopting the above technical solution, the rotating ring is rotated and the threaded connection between the rotating ring and the fixed ring is utilized to make the rotating ring move laterally. At the same time, this movement causes the inner side of the rotating ring to press against the spring sheet at an angle, causing the spring sheet to undergo elastic deformation. This deformation causes the friction sheet on the inner side of the spring sheet to fit tightly against the inner sleeve shell, thereby increasing the contact friction between the outer sleeve and the inner sleeve shell.

[0009] It is further provided that a plurality of the spring sheets are provided, and the plurality of the spring sheets are arranged in an equidistant ring shape along the central axis of the fixing ring, and a gap is formed between two adjacent spring sheets.

[0010] By adopting the above technical solution, multiple spring sheets are arranged in an equidistant ring along the central axis of the fixed ring, which can ensure that when the rotating ring moves and forms an inclined pressure with the spring sheets, the force distribution is more uniform. This uniform distribution not only enhances the stability of the structure, but also prevents damage caused by excessive stress at a single point.

[0011] It is further provided that the medicine dispensing assembly comprises an outer sleeve, and the outer sleeve is fixedly connected to the spring sheet.

[0012] By adopting the above technical solution, the fixed connection between the outer sleeve and the spring sheet ensures the stability and reliability of the medicine dispensing device. This connection method enables the spring sheet to be firmly attached to the outer sleeve and will not fall off or shift during operation.

[0013] It is further provided that the inner sleeve assembly comprises an inner sleeve shell, a friction sheet is provided on the inner side of the spring sheet, and the friction sheet abuts against the outer surface of the inner sleeve shell.

[0014] By adopting the above technical solution, the friction plate arranged on the inner side of the spring plate directly contacts the outer surface of the inner shell, which increases the friction between the two.

[0015] It is further provided that a groove is provided on the inner side of the inner shell, and the groove is adapted to fit the insulin bottle.

[0016] By adopting the above technical solution, the groove opened on the inner side of the inner shell is adapted to the insulin bottle, which ensures that the bottle can be firmly placed in the inner shell. At the same time, the adapted groove provides a safe storage space for the insulin bottle, which can effectively prevent the bottle from shaking or shifting during the drug removal process, thereby ensuring the accuracy and safety of drug removal.

[0017] It is further configured that a piston block is provided on one side of the interior of the insulin bottle, a pressure rod is provided at the central axis of the outer sleeve, the pressure rod is opposite to the piston block, and a rotating block is provided at the end of the pressure rod.

[0018] By adopting the above technical solution, the piston block and the pressure rod at the center axis of the outer sleeve are located opposite to each other, so that the pressure rod can accurately push the piston block.

[0019] It is further provided that the outer sleeve is threadedly connected to the inner shell, and the medicine dispenser comprises a sleeve block, and the sleeve block is threadedly connected to the inner shell.

[0020] By adopting the above technical solution, the threaded connection enables the two to be tightly and firmly combined together, ensuring the integrity and stability of the medicine dispensing device. At the same time, this connection method also makes it easy for the user to adjust the pressure of the pressure rod on the piston block by rotating the outer sleeve, thereby controlling the amount of insulin taken.

[0021] It is further provided that a limiting block is provided on one side of the inner shell, and a thimble is provided on one side of the inner sleeve block. The thimble passes through the limiting block and is used to puncture the insulin bottle.

[0022] By adopting the above technical solution, the limit block provides a stable support and positioning for the ejector pin, ensuring that the ejector pin can accurately puncture the insulin bottle.

[0023] It is further provided that a mounting sleeve is provided on the other side of the sleeve block, and the mounting sleeve is engaged with the thread of the ampoule bottle.

[0024] By adopting the above technical solution, the mounting sleeve provides a stable connection point for the ampoule bottle, and the ampoule bottle can be tightly and safely fixed on the medicine dispensing device through threaded engagement, which effectively prevents the ampoule bottle from falling off or loosening during the medicine dispensing process.

[0025] It is further provided that a plurality of anti-sliding blocks are provided on the outer sides of the rotating ring and the outer sleeve.

[0026] By adopting the above technical solution, multiple anti-slip blocks are provided on the outer sides of the rotating ring and the outer sleeve, which provides the user with a better hand grip when operating the medicine dispensing device. The anti-slip blocks increase the friction between the hand and the device, making the user more stable when rotating or holding the device and not easy to slip out of the hand.

[0027] Compared with the related art, the new single-piece flexible medicine dispensing device provided by the utility model has the following beneficial effects:

[0028] The utility model provides a novel single-piece flexible medicine taking device. Through a limiting mechanism, a rotating ring is rotated. This action utilizes the threaded connection between the rotating ring and the fixed ring. As the lateral position of the rotating ring moves, its inner side will form an inclined surface pressure with a spring sheet, thereby causing the spring sheet to undergo elastic deformation. This deformation in turn causes the friction sheet on the inner side of the spring sheet to tightly abut against the inner sleeve shell. This is done in order to increase the contact friction between the outer sleeve and the inner sleeve shell. Through this mechanism, further threaded rotation between the outer sleeve and the inner sleeve shell can be effectively prevented, thereby avoiding overflow of medicine inside the insulin medicine bottle after the ampoule bottle is released.

DETAILED DESCRIPTION

[0036] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0037] Embodiment 1:

[0038] like Figure 1 , Figure 5 , Figure 6As shown, the novel single-piece flexible medicine dispensing device of the utility model comprises: a medicine dispensing component 1, an inner sleeve component 2, a medicine dispensing device 3, an ampoule bottle 4 and an insulin medicine bottle 6, the medicine dispensing component 1 comprises an outer sleeve 101, a limiting mechanism 5 is arranged on one side of the outer sleeve 101, the limiting mechanism 5 comprises a fixed ring 501, a rotating ring 504 is threadedly connected to the outer side of the fixed ring 501, a spring sheet 502 is arranged on the inner side of the fixed ring 501, an inclined surface 505 is formed on the outer side of the spring sheet 502 and the inner side of the rotating ring 504, the rotating ring 504 is rotated, and the rotating ring 504 is threadedly connected to the fixed ring 501, so that the rotating ring 504 The outer sleeve 101 and the inner sleeve 201 are connected to each other with a screw thread to move laterally. At the same time, this movement causes the inner side of the rotating ring to be pressed against the spring sheet 502 at an angle, resulting in elastic deformation of the spring sheet. This deformation causes the friction sheet 503 on the inner side of the spring sheet 502 to fit tightly against the inner sleeve 201, thereby increasing the contact friction between the outer sleeve 101 and the inner sleeve 201, and effectively preventing further threaded rotation between the outer sleeve 101 and the inner sleeve 201, thereby avoiding overflow of the medicine inside the insulin bottle 6 after the ampoule bottle 4 is removed. In this way, the convenience of using the medicine taking device is significantly improved, and the safety of medicine use is also enhanced.

[0039] like Figure 1 , Figure 5 , Figure 6 As shown, a plurality of spring sheets 502 are provided, and the plurality of spring sheets 502 are arranged in an equidistant ring shape along the central axis of the fixing ring 501, and a gap is formed between two adjacent spring sheets 502. The plurality of spring sheets 502 are arranged in an equidistant ring shape along the central axis of the fixing ring 501, so that when the rotating ring 504 moves and forms an inclined surface pressure with the spring sheets 502, the force distribution is more uniform. This uniform distribution not only enhances the stability of the structure, but also prevents damage caused by excessive stress at a single point. At the same time, a gap is formed between two adjacent spring sheets 502. This design not only ensures that the spring sheets 502 have enough space for elastic deformation, but also avoids mutual interference that may be caused by close arrangement.

[0040] Embodiment 2:

[0041] like Figure 1 , Figure 2 , Figure 3 As shown, the medicine dispensing assembly 1 includes an outer sleeve 101, and the outer sleeve 101 is fixedly connected to the spring sheet 502. The fixed connection between the outer sleeve 101 and the spring sheet 502 ensures the stability and reliability of the medicine dispensing device. This connection method enables the spring sheet 502 to be firmly attached to the outer sleeve 101 and will not fall off or shift during operation. At the same time, the fixed connection also means that when the rotating ring 504 is rotated, the spring sheet 502 can accurately respond and produce the required elastic deformation, thereby effectively adjusting the friction between the outer sleeve 101 and the inner sleeve shell 201 to prevent accidental spillage of medicine.

[0042] like Figure 1 , Figure 2 , Figure 3 As shown, the inner sleeve assembly 2 includes an inner sleeve shell 201, and a friction plate 503 is arranged on the inner side of the spring plate 502, and the friction plate 503 abuts against the outer surface of the inner sleeve shell 201. The friction plate 503 arranged on the inner side of the spring plate 502 directly abuts against the outer surface of the inner sleeve shell 201, which increases the friction between the two. At the same time, when the rotating ring 504 applies pressure to the inner sleeve shell 201 through the spring plate 502, the friction plate 503 can effectively prevent the relative rotation between the outer sleeve 101 and the inner sleeve shell 201, which not only improves the stability of the medicine dispensing device during use, but also effectively avoids the overflow of the medicine inside the insulin bottle 6 after the ampoule bottle 4 is released, thereby ensuring the safety and reliability of the medicine dispensing device.

[0043] like Figure 1 , Figure 2 , Figure 3 As shown, a groove 202 is provided on the inner side of the inner shell 201, and the groove 202 is adapted to the insulin bottle 6. The groove 202 provided on the inner side of the inner shell 201 is adapted to the insulin bottle 6, which ensures that the bottle can be firmly placed in the inner shell 201. At the same time, the adapted groove 202 provides a safe storage space for the insulin bottle 6, which can effectively prevent the bottle from shaking or shifting during the drug taking process, thereby ensuring the accuracy and safety of drug taking. In addition, the groove 202 also makes the placement and removal of the bottle simple and convenient, thereby improving the convenience of use of the drug taking device.

[0044] like Figure 1 , Figure 2 As shown, a piston block 7 is provided on one side of the interior of the insulin bottle 6, and a pressure rod 102 is provided at the central axis of the outer sleeve 101. The pressure rod 102 is opposite to the piston block 7, and a rotating block 103 is provided at the end of the pressure rod 102. The piston block 7 is opposite to the pressure rod 102 at the central axis of the outer sleeve 101, so that the pressure rod 102 can accurately push the piston block 7. At the same time, the rotating block 103 at the end of the pressure rod 102 can reduce friction, making the pressing process smoother and preventing jamming during the pushing process. Such a structure not only improves the efficiency of taking medicine, but also ensures the stability and accuracy of the medicine taking process.

[0045] like Figure 1 , Figure 2 , Figure 3As shown, the outer sleeve 101 is threadedly connected to the inner shell 201, and the medicine dispenser 3 includes a sleeve block 301, which is threadedly connected to the inner shell 201. The threaded connection allows the two to be tightly and firmly combined together, ensuring the integrity and stability of the medicine dispensing device. At the same time, this connection method is also convenient for the user to adjust the pressure of the pressure rod 102 on the piston block 7 by rotating the outer sleeve 101, thereby controlling the amount of insulin taken. In addition, the sleeve block 301 and the inner shell 201 are also threadedly connected, which not only enhances the stability of the medicine dispenser, but also facilitates the installation and disassembly of the medicine dispenser, making the entire medicine dispensing process simpler and faster.

[0046] like Figure 1 , Figure 2 As shown, a limiting block 203 is provided on one side of the inner sleeve shell 201, and a ejector pin 302 is provided on one side of the inner sleeve block 301. The ejector pin 302 penetrates the limiting block 203 and is used to puncture the insulin vial 6. The limiting block 203 provides a stable support and positioning for the ejector pin 302, ensuring that the ejector pin can accurately puncture the insulin vial 6. At the same time, the ejector pin 302 inside the sleeve block 301 penetrates the limiting block 203, so that the ejector pin 302 can directly and accurately puncture the sealing port of the vial, thereby establishing a smooth channel, allowing the insulin to be smoothly transferred from the vial to the ampoule bottle 4.

[0047] like Figure 3 As shown, a mounting sleeve 303 is provided on the other side of the interior of the socket block 301, and the mounting sleeve 303 is threadedly engaged with the ampoule bottle 4. The mounting sleeve 303 provides a stable connection point for the ampoule bottle 4. Through the threaded engagement, the ampoule bottle 4 can be tightly and safely fixed on the medicine dispensing device, which effectively prevents the ampoule bottle 4 from falling off or loosening during the medicine dispensing process. At the same time, this threaded connection method also makes the installation and disassembly of the ampoule bottle 4 simple and quick, greatly improving the convenience of use of the medicine dispensing device. In general, the threaded engagement between the mounting sleeve 303 and the ampoule bottle 4 enhances the stability and ease of use of the medicine dispensing device.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, multiple anti-sliding blocks 8 are provided on the outer sides of the rotating ring 504 and the outer sleeve 101. Multiple anti-sliding blocks 8 are provided on the outer sides of the rotating ring 504 and the outer sleeve 101, which provide the user with a better hand grip when operating the medicine dispensing device. The anti-sliding blocks 8 increase the friction between the hand and the device, so that the user can be more stable when rotating or holding the device and it is not easy to slip out of the hand. At the same time, the anti-sliding blocks 8 also reduce the risk of slipping caused by hand sweat, thereby improving the safety of the use process. In general, the setting of the anti-sliding blocks 8 enhances the operational stability and safety of the medicine dispensing device.

[0049] During implementation, the insulin bottle 6 is placed inside the groove 202, and then the outer sleeve 101 is rotated, and the threaded connection between the outer sleeve 101 and the inner shell 201 is used to cause the inner pressing rod 102 to abut against one side of the insulin bottle 6, and then the sleeve block 301 is threadedly connected to the other side of the inner shell 201, and the ejector pin 302 is used to penetrate the limit block 203 to puncture the insulin bottle 6, and then the end of the ampoule bottle 4 is threadedly engaged with the mounting sleeve 303 on one side of the sleeve block 301, and then, the threaded connection between the outer sleeve 101 and the inner shell 201 causes the inner pressing rod 102 to move the piston block 7 inside the insulin bottle 6, at this time, the insulin inside the insulin bottle 6 is transported to the inside of the ampoule bottle 4 through the gap inside the ejector pin 302 due to the high pressure, until an appropriate amount of insulin is taken out, and the insulin removal operation of the ampoule bottle 4 is completed;

[0050] After the medicine is taken out, first, rotate the rotating ring 504, and use the threaded connection between the rotating ring 504 and the fixed ring 501 to prompt the rotating ring 504 to move in the lateral position. At the same time, the inner side is pressed against the spring sheet 502 at an inclined surface, causing the spring sheet 502 to elastically deform, and use the friction plate 503 on the inner side of the spring sheet 502 to abut against the inner shell 201, which is beneficial to increase the contact friction between the outer sleeve 101 and the inner shell 201, and prevent the outer sleeve 101 and the inner shell 201 from further threading. This prevents the overflow of medicine inside the insulin bottle 6 after the ampoule bottle 4 is released, thereby improving the convenience of use of the medicine taking device. Afterwards, release the connection between the ampoule bottle 4 and the mounting sleeve 303.

[0051] The advantages of this technical solution in practical applications include but are not limited to the following:

[0052] 1. The friction plate 503 on the inner side of the spring plate 502 is tightly against the inner casing 201. The purpose of this is to increase the contact friction between the outer sleeve 101 and the inner casing 201. Through this mechanism, further thread rotation between the outer sleeve 101 and the inner casing 201 can be effectively prevented, thereby avoiding the overflow of the medicine inside the insulin bottle 6 after the ampoule bottle 4 is released;

[0053] 2. By further rotating the threaded connection between the outer sleeve 101 and the inner sleeve shell 201, the inner pressure rod 102 pushes the piston block 7 inside the insulin bottle 6 to move its position. This action generates high pressure, forcing the insulin inside the insulin bottle 6 to be accurately delivered to the inside of the ampoule bottle 4 through the gap inside the ejector pin 302.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
